Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.
If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.
I had the same issue while adding firebase to my Ionic App. To fix the issue I followed these steps:
npm install @angular/fire firebase --save
In my app/app.module.ts:
...
import { AngularFireModule } from '@angular/fire';
import { environment } from '../environments/environment';
import { AngularFirestoreModule, SETTINGS } from '@angular/fire/firestore';
@NgModule({
declarations: [AppComponent],
entryComponents: [],
imports: [
BrowserModule,
AppRoutingModule,
AngularFireModule.initializeApp(environment.firebase),
AngularFirestoreModule
],
providers: [
{ provide: SETTINGS, useValue: {} }
],
bootstrap: [AppComponent]
})
Previously we used FirestoreSettingsToken instead of SETTINGS. But that bug got resolved, now we use SETTINGS. (link)
In my app/services/myService.ts I imported as:
import { AngularFirestore } from "@angular/fire/firestore";
For some reason vscode was importing it as "@angular/fire/firestore/firestore";I After changing it for "@angular/fire/firestore"; the issue got resolved!

I ran into this error while trying to click some element (or its overlay, I didn't care), and the other answers didn't work for me. I fixed it by using the elementFromPoint
DOM API to find the element that Selenium wanted me to click on instead:
element_i_care_about = something()
loc = element_i_care_about.location
element_to_click = driver.execute_script(
"return document.elementFromPoint(arguments[0], arguments[1]);",
loc['x'],
loc['y'])
element_to_click.click()
I've also had situations where an element was moving, for example because an element above it on the page was doing an animated expand or collapse. In that case, this Expected Condition class helped. You give it the elements that are animated, not the ones you want to click. This version only works for jQuery animations.
class elements_not_to_be_animated(object):
def __init__(self, locator):
self.locator = locator
def __call__(self, driver):
try:
elements = EC._find_elements(driver, self.locator)
# :animated is an artificial jQuery selector for things that are
# currently animated by jQuery.
return driver.execute_script(
'return !jQuery(arguments[0]).filter(":animated").length;',
elements)
except StaleElementReferenceException:
return False
You have to use setState
to set a property that will render the <Redirect>
inside your render()
method.
E.g.
class MyComponent extends React.Component {
state = {
redirect: false
}
handleSubmit () {
axios.post(/**/)
.then(() => this.setState({ redirect: true }));
}
render () {
const { redirect } = this.state;
if (redirect) {
return <Redirect to='/somewhere'/>;
}
return <RenderYourForm/>;
}
You can also see an example in the official documentation: https://reacttraining.com/react-router/web/example/auth-workflow
That said, I would suggest you to put the API call inside a service or something. Then you could just use the history
object to route programatically. This is how the integration with redux works.
But I guess you have your reasons to do it this way.
Another variant to POST this content type and which does not use a dictionary would be:
StringContent postData = new StringContent(JSON_CONTENT, Encoding.UTF8, "application/x-www-form-urlencoded");
using (HttpResponseMessage result = httpClient.PostAsync(url, postData).Result)
{
string resultJson = result.Content.ReadAsStringAsync().Result;
}
All nice solutions, borrowing and improvising for special case -> If you want to add a label near the arrowhead:
arr = [2,3]
txt = “Vector X”
ax.annotate(txt, arr)
ax.arrow(0, 0, *arr, head_width=0.05, head_length=0.1)
On client:
axios.get('/api', {
params: {
foo: 'bar'
}
});
On server:
function get(req, res, next) {
let param = req.query.foo
.....
}
You need to include jQueryUI

The apiKey in this configuration snippet just identifies your Firebase project on the Google servers. It is not a security risk for someone to know it. In fact, it is necessary for them to know it, in order for them to interact with your Firebase project. This same configuration data is also included in every iOS and Android app that uses Firebase as its backend.
In that sense it is very similar to the database URL that identifies the back-end database associated with your project in the same snippet: https://<app-id>.firebaseio.com
. See this question on why this is not a security risk: How to restrict Firebase data modification?, including the use of Firebase's server side security rules to ensure only authorized users can access the backend services.
If you want to learn how to secure all data access to your Firebase backend services is authorized, read up on the documentation on Firebase security rules. These rules control access to file storage and database access, and are enforced on the Firebase servers. So no matter if it's your code, or somebody else's code that uses you configuration data, it can only do what the security rules allow it to do.
For another explanation of what Firebase uses these values for, and for which of them you can set quotas, see the Firebase documentation on using and managing API keys.
If you'd like to reduce the risk of committing this configuration data to version control, consider using the SDK auto-configuration of Firebase Hosting. While the keys will still end up in the browser in the same format, they won't be hard-coded into your code anymore with that.

Angular4
Instead of
this.renderer.invokeElementMethod(
this.fileInput.nativeElement, 'dispatchEvent', [event]);
use
this.fileInput.nativeElement.dispatchEvent(event);
because invokeElementMethod
won't be part of the renderer anymore.
Angular2
Use ViewChild with a template variable to get a reference to the file input, then use the Renderer to invoke dispatchEvent
to fire the event:
import { Component, Renderer, ElementRef, ViewChild } from '@angular/core';
@Component({
...
template: `
...
<input #fileInput type="file" id="imgFile" (click)="onChange($event)" >
...`
})
class MyComponent {
@ViewChild('fileInput') fileInput:ElementRef;
constructor(private renderer:Renderer) {}
showImageBrowseDlg() {
// from http://stackoverflow.com/a/32010791/217408
let event = new MouseEvent('click', {bubbles: true});
this.renderer.invokeElementMethod(
this.fileInput.nativeElement, 'dispatchEvent', [event]);
}
}
Update
Since direct DOM access isn't discouraged anymore by the Angular team this simpler code can be used as well
this.fileInput.nativeElement.click()
See also https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/dispatchEvent
You can run CMD as Administrator and change the permission of the directory using cacls.exe. For example:
cacls.exe c: /t /e /g everyone:F # means everyone can totally control the C: disc
When I align elements in center I use the bootstrap class text-center:
<div class="text-center">Centered content goes here</div>
Uploading Files using Retrofit is Quite Simple You need to build your api interface as
public interface Api {
String BASE_URL = "http://192.168.43.124/ImageUploadApi/";
@Multipart
@POST("yourapipath")
Call<MyResponse> uploadImage(@Part("image\"; filename=\"myfile.jpg\" ") RequestBody file, @Part("desc") RequestBody desc);
}
in the above code image is the key name so if you are using php you will write $_FILES['image']['tmp_name'] to get this. And filename="myfile.jpg" is the name of your file that is being sent with the request.
Now to upload the file you need a method that will give you the absolute path from the Uri.
private String getRealPathFromURI(Uri contentUri) {
String[] proj = {MediaStore.Images.Media.DATA};
CursorLoader loader = new CursorLoader(this, contentUri, proj, null, null, null);
Cursor cursor = loader.loadInBackground();
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String result = cursor.getString(column_index);
cursor.close();
return result;
}
Now you can use the below code to upload your file.
private void uploadFile(Uri fileUri, String desc) {
//creating a file
File file = new File(getRealPathFromURI(fileUri));
//creating request body for file
RequestBody requestFile = RequestBody.create(MediaType.parse(getContentResolver().getType(fileUri)), file);
RequestBody descBody = RequestBody.create(MediaType.parse("text/plain"), desc);
//The gson builder
Gson gson = new GsonBuilder()
.setLenient()
.create();
//creating retrofit object
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Api.BASE_URL)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
//creating our api
Api api = retrofit.create(Api.class);
//creating a call and calling the upload image method
Call<MyResponse> call = api.uploadImage(requestFile, descBody);
//finally performing the call
call.enqueue(new Callback<MyResponse>() {
@Override
public void onResponse(Call<MyResponse> call, Response<MyResponse> response) {
if (!response.body().error) {
Toast.makeText(getApplicationContext(), "File Uploaded Successfully...", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), "Some error occurred...", Toast.LENGTH_LONG).show();
}
}
@Override
public void onFailure(Call<MyResponse> call, Throwable t) {
Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_LONG).show();
}
});
}

To get specific view from recycler view list OR show error at edittext of recycler view.
private void popupErrorMessageAtPosition(int itemPosition) {
RecyclerView.ViewHolder viewHolder = recyclerView.findViewHolderForAdapterPosition(itemPosition);
View view = viewHolder.itemView;
EditText etDesc = (EditText) view.findViewById(R.id.et_description);
etDesc.setError("Error message here !");
}
Actually you can add in your manifest these lines android:hardwareAccelerated="false"
, android:largeHeap="true"
it is working for some situations, but be aware that the other part of code can be arguing with this.
<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme">
If your data changes a lot, you can use
mAdapter.notifyItemRangeChanged(0, yourData.size());
or some single items in your data set changes, your can use
mAdapter.notifyItemChanged(pos);
For detailed methods usage, you can refer the doc, in a way, try not to directly use mAdapter.notifyDataSetChanged()
.
Another option is to use diffutil . It will compare the original list against the new list and use the new list as the update if there is a change.
Basically, we can use DiffUtil to compare the old data vs new data and let it call notifyItemRangeRemoved, and notifyItemRangeChanged and notifyItemRangeInserted on your behalf.
A quick example of using diffUtil instead of notifyDataSetChanged:
DiffResult diffResult = DiffUtil
.calculateDiff(new MyDiffUtilCB(getItems(), items));
//any clear up on memory here and then
diffResult.dispatchUpdatesTo(this);
//and then, if necessary
items.clear()
items.addAll(newItems)
I do the calculateDiff work off the main thread in case it's a big list.
"How can I directly (without saving the file on 2nd server) download the file from 1st server to client's machine?"
Just use the Client
API and get the InputStream
from the response
Client client = ClientBuilder.newClient();
String url = "...";
final InputStream responseStream = client.target(url).request().get(InputStream.class);
There are two flavors to get the InputStream
. You can also use
Response response = client.target(url).request().get();
InputStream is = (InputStream)response.getEntity();
Which one is the more efficient? I'm not sure, but the returned InputStream
s are different classes, so you may want to look into that if you care to.
From 2nd server I can get a ByteArrayOutputStream to get the file from 1st server, can I pass this stream further to the client using the REST service?
So most of the answers you'll see in the link provided by @GradyGCooper seem to favor the use of StreamingOutput
. An example implementation might be something like
final InputStream responseStream = client.target(url).request().get(InputStream.class);
System.out.println(responseStream.getClass());
StreamingOutput output = new StreamingOutput() {
@Override
public void write(OutputStream out) throws IOException, WebApplicationException {
int length;
byte[] buffer = new byte[1024];
while((length = responseStream.read(buffer)) != -1) {
out.write(buffer, 0, length);
}
out.flush();
responseStream.close();
}
};
return Response.ok(output).header(
"Content-Disposition", "attachment, filename=\"...\"").build();
But if we look at the source code for StreamingOutputProvider, you'll see in the writeTo
, that it simply writes the data from one stream to another. So with our implementation above, we have to write twice.
How can we get only one write? Simple return the InputStream
as the Response
final InputStream responseStream = client.target(url).request().get(InputStream.class);
return Response.ok(responseStream).header(
"Content-Disposition", "attachment, filename=\"...\"").build();
If we look at the source code for InputStreamProvider, it simply delegates to ReadWriter.writeTo(in, out)
, which simply does what we did above in the StreamingOutput
implementation
public static void writeTo(InputStream in, OutputStream out) throws IOException {
int read;
final byte[] data = new byte[BUFFER_SIZE];
while ((read = in.read(data)) != -1) {
out.write(data, 0, read);
}
}
Asides:
Client
objects are expensive resources. You may want to reuse the same Client
for request. You can extract a WebTarget
from the client for each request.
WebTarget target = client.target(url);
InputStream is = target.request().get(InputStream.class);
I think the WebTarget
can even be shared. I can't find anything in the Jersey 2.x documentation (only because it is a larger document, and I'm too lazy to scan through it right now :-), but in the Jersey 1.x documentation, it says the Client
and WebResource
(which is equivalent to WebTarget
in 2.x) can be shared between threads. So I'm guessing Jersey 2.x would be the same. but you may want to confirm for yourself.
You don't have to make use of the Client
API. A download can be easily achieved with the java.net
package APIs. But since you're already using Jersey, it doesn't hurt to use its APIs
The above is assuming Jersey 2.x. For Jersey 1.x, a simple Google search should get you a bunch of hits for working with the API (or the documentation I linked to above)
I'm such a dufus. While the OP and I are contemplating ways to turn a ByteArrayOutputStream
to an InputStream
, I missed the simplest solution, which is simply to write a MessageBodyWriter
for the ByteArrayOutputStream
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.MessageBodyWriter;
import javax.ws.rs.ext.Provider;
@Provider
public class OutputStreamWriter implements MessageBodyWriter<ByteArrayOutputStream> {
@Override
public boolean isWriteable(Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType) {
return ByteArrayOutputStream.class == type;
}
@Override
public long getSize(ByteArrayOutputStream t, Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType) {
return -1;
}
@Override
public void writeTo(ByteArrayOutputStream t, Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType,
MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream)
throws IOException, WebApplicationException {
t.writeTo(entityStream);
}
}
Then we can simply return the ByteArrayOutputStream
in the response
return Response.ok(baos).build();
D'OH!
Here are the tests I used (
Resource class
@Path("test")
public class TestResource {
final String path = "some_150_mb_file";
@GET
@Produces(MediaType.APPLICATION_OCTET_STREAM)
public Response doTest() throws Exception {
InputStream is = new FileInputStream(path);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int len;
byte[] buffer = new byte[4096];
while ((len = is.read(buffer, 0, buffer.length)) != -1) {
baos.write(buffer, 0, len);
}
System.out.println("Server size: " + baos.size());
return Response.ok(baos).build();
}
}
Client test
public class Main {
public static void main(String[] args) throws Exception {
Client client = ClientBuilder.newClient();
String url = "http://localhost:8080/api/test";
Response response = client.target(url).request().get();
String location = "some_location";
FileOutputStream out = new FileOutputStream(location);
InputStream is = (InputStream)response.getEntity();
int len = 0;
byte[] buffer = new byte[4096];
while((len = is.read(buffer)) != -1) {
out.write(buffer, 0, len);
}
out.flush();
out.close();
is.close();
}
}
So the final solution for this particular use case was for the OP to simply pass the OutputStream
from the StreamingOutput
's write
method. Seems the third-party API, required a OutputStream
as an argument.
StreamingOutput output = new StreamingOutput() {
@Override
public void write(OutputStream out) {
thirdPartyApi.downloadFile(.., .., .., out);
}
}
return Response.ok(output).build();
Not quite sure, but seems the reading/writing within the resource method, using ByteArrayOutputStream`, realized something into memory.
The point of the downloadFile
method accepting an OutputStream
is so that it can write the result directly to the OutputStream
provided. For instance a FileOutputStream
, if you wrote it to file, while the download is coming in, it would get directly streamed to the file.
It's not meant for us to keep a reference to the OutputStream
, as you were trying to do with the baos
, which is where the memory realization comes in.
So with the way that works, we are writing directly to the response stream provided for us. The method write
doesn't actually get called until the writeTo
method (in the MessageBodyWriter
), where the OutputStream
is passed to it.
You can get a better picture looking at the MessageBodyWriter
I wrote. Basically in the writeTo
method, replace the ByteArrayOutputStream
with StreamingOutput
, then inside the method, call streamingOutput.write(entityStream)
. You can see the link I provided in the earlier part of the answer, where I link to the StreamingOutputProvider
. This is exactly what happens
Turns out the binding of style to a string doesn't work. The solution would be to bind the background of the style.
<div class="circle" [style.background]="color">
In the model, write the below code;
public $timestamps = false;
This would work.

Not a specific answer to your question but I had got this error when I hadn't set an initial value for an enum while declaring it as a property. I assigned a initial value to the enum to resolve this error. Posting here as it might help someone.
Make this entry in dimens
<!--Floating action button-->
<dimen name="design_fab_image_size" tools:override="true">36dp</dimen>
Here 36dp is icon size on floating point button. This will set 36dp size for all icons for floating action button.
Updates As Per Comments
If you want to set icon size to particular Floating Action Button just go with Floating action button attributes like app:fabSize="normal" and android:scaleType="center".
<!--app:fabSize decides size of floating action button You can use normal, auto or mini as per need-->
app:fabSize="normal"
<!--android:scaleType decides how the icon drawable will be scaled on Floating action button. You can use center(to show scr image as original), fitXY, centerCrop, fitCenter, fitEnd, fitStart, centerInside.-->
android:scaleType="center"
Here is one aditional free Floating Action Button library for Android It has many customizations and requires SDK version 9 and higher
Final working solution:
public static String getFileName(Uri uri) {
try {
String path = uri.getLastPathSegment();
return path != null ? path.substring(path.lastIndexOf("/") + 1) : "unknown";
} catch (Exception e) {
e.printStackTrace();
}
return "unknown";
}
First you need to declare your resources in dispatcher-servlet file like this :
<mvc:resources mapping="/resources/**" location="/resources/folder/" />
Any request with url mapping /resources/** will directly look for /resources/folder/.
Now in jsp file you need to include your css file like this :
<link href="<c:url value="/resources/css/main.css" />" rel="stylesheet">
Similarly you can include js files.
Hope this solves your problem.

Old post, but I thought I would share my solution because there aren't many solutions out there for this issue.
If you're running an old Windows Server 2003 machine, you likely need to install a hotfix (KB938397).
This problem occurs because the Cryptography API 2 (CAPI2) in Windows Server 2003 does not support the SHA2 family of hashing algorithms. CAPI2 is the part of the Cryptography API that handles certificates.
https://support.microsoft.com/en-us/kb/938397
For whatever reason, Microsoft wants to email you this hotfix instead of allowing you to download directly. Here's a direct link to the hotfix from the email:

As a different approach to the other answer, instead of indicating the user upon image creation on the Dockerfile, you can do so via command-line on a particular container as a per-command basis.
With docker exec
, use --user
to specify which user account the interactive terminal will use (the container should be running and the user has to exist in the containerized system):
docker exec -it --user [username] [container] bash
See https://docs.docker.com/engine/reference/commandline/exec/
I had this when build my application with "All cpu" target while it referenced a 3rd party x64-only (managed) dll.
I had the same error, although in my case the problem was with the formatting of the DESTINATION path. The comments above are correct with respect to debugging the path string formatting, but there seems to be a bug in the File.Copy exception reporting where it still throws back the SOURCE path instead of the DESTINATION path. So don't forget to look here as well.

The solution for this problem is just to add overflow: auto;
to the .content for making the content wrapper scrollable.
Furthermore, there are circumstances occurring along with Flexbox wrapper and overflowed
scrollable content like this codepen.
The solution is to add overflow: hidden (or auto);
to the parent of the wrapper (set with overflow: auto;) around large contents.

Near the top of the code with the Public Workshop(), I am assumeing this bit,
suitButton = new JCheckBox("Suit");
suitButton.setMnemonic(KeyEvent.VK_Y);
suitButton = new JCheckBox("Denim Jeans");
suitButton.setMnemonic(KeyEvent.VK_U);
should maybe be,
suitButton = new JCheckBox("Suit");
suitButton.setMnemonic(KeyEvent.VK_Y);
denimjeansButton = new JCheckBox("Denim Jeans");
denimjeansButton.setMnemonic(KeyEvent.VK_U);
Setting these exact configurations helped resolving the issue.

You Can not Use the Intent's Context
for Creating Intent. So You need to use your Fragment's
Parent Activity
Context
Intent intent = new Intent(getActivity(),MyClass.class);
I used the solution below to export all datagrid values to a text file, rather than using the column names you can use the column index instead.
foreach (DataGridViewRow row in xxxCsvDG.Rows)
{
File.AppendAllText(csvLocation, row.Cells[0].Value + "," + row.Cells[1].Value + "," + row.Cells[2].Value + "," + row.Cells[3].Value + Environment.NewLine);
}
For managing DataBase Objects in SQL Server i would suggest using Server Management Objects
ListView myListView = (ListView) rootView.findViewById(R.id.myListView);
ArrayList<String> myStringArray1 = new ArrayList<String>();
myStringArray1.add("something");
adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
myListView.setAdapter(adapter);
Try it like this
public OnClickListener moreListener = new OnClickListener() {
@Override
public void onClick(View v) {
adapter = null;
myStringArray1.add("Andrea");
adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
myListView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
};

Here is simple way using HTML5 and jQuery:
1) include two JS file
<script src="jslibs/jquery.js" type="text/javascript"></script>
<script src="jslibs/ajaxupload-min.js" type="text/javascript"></script>
2) include CSS to have cool buttons
<link rel="stylesheet" href="css/baseTheme/style.css" type="text/css" media="all" />
3) create DIV or SPAN
<div class="demo" > </div>
4) write this code in your HTML page
$('.demo').ajaxupload({
url:'upload.php'
});
5) create you upload.php file to have PHP code to upload data.
You can download required JS file from here Here is Example
Its too cool and too fast And easy too! :)
My Code to insert data is not working. It showing no error but data is not showing in my database.
public partial class Form1 : Form { OleDbConnection connection = new OleDbConnection(check.Properties.Settings.Default.KitchenConnectionString); public Form1() { InitializeComponent(); }
private void Form1_Load(object sender, EventArgs e)
{
}
private void btn_add_Click(object sender, EventArgs e)
{
OleDbDataAdapter items = new OleDbDataAdapter();
connection.Open();
OleDbCommand command = new OleDbCommand("insert into Sets(SetId, SetName, SetPassword) values('"+txt_id.Text+ "','" + txt_setname.Text + "','" + txt_password.Text + "');", connection);
command.CommandType = CommandType.Text;
command.ExecuteReader();
connection.Close();
MessageBox.Show("Insertd!");
}
}
Update or Delete with sql transaction
private void SQLTransaction() {
try {
string sConnectionString = "My Connection String";
string query = "UPDATE [dbo].[MyTable] SET ColumnName = '{0}' WHERE ID = {1}";
SqlConnection connection = new SqlConnection(sConnectionString);
SqlCommand command = connection.CreateCommand();
connection.Open();
SqlTransaction transaction = connection.BeginTransaction("");
command.Transaction = transaction;
try {
foreach(DataRow row in dt_MyData.Rows) {
command.CommandText = string.Format(query, row["ColumnName"].ToString(), row["ID"].ToString());
command.ExecuteNonQuery();
}
transaction.Commit();
} catch (Exception ex) {
transaction.Rollback();
MessageBox.Show(ex.Message, "Error");
}
} catch (Exception ex) {
MessageBox.Show("Problem connect to database.", "Error");
}
}
I have a sample program for this:
public class BrowserBackForward {
/**
* @param args
* @throws InterruptedException
*/
public static void main(String[] args) throws InterruptedException {
WebDriver driver = new FirefoxDriver();
driver.get("http://seleniumhq.org/");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
//maximize the window
driver.manage().window().maximize();
driver.findElement(By.linkText("Documentation")).click();
System.out.println(driver.getCurrentUrl());
driver.navigate().back();
System.out.println(driver.getCurrentUrl());
Thread.sleep(30000);
driver.navigate().forward();
System.out.println("Forward");
Thread.sleep(30000);
driver.navigate().refresh();
}
}
There are many ways, for example:
Method one:
public string test()
{
string ErrMsg = string.Empty;
try
{
int num = int.Parse("gagw");
}
catch (Exception ex)
{
ErrMsg = ex.Message;
}
return ErrMsg
}
Method two:
public void test(ref string ErrMsg )
{
ErrMsg = string.Empty;
try
{
int num = int.Parse("gagw");
}
catch (Exception ex)
{
ErrMsg = ex.Message;
}
}
From what I know, the correct syntax is:
function ChangeBackgroungImageOfTab(tabName, imagePrefix)
{
document.getElementById(tabName).style.backgroundImage = "url('buttons/" + imagePrefix + ".png')";
}
So basically, getElementById(tabName).backgroundImage
and split the string like:
"cssInHere('and" + javascriptOutHere + "/cssAgain')";
Try this in your constructor
MainActivity maniActivity = (MainActivity)context;
EditText firstName = (EditText) maniActivity.findViewById(R.id.display_name);
<gradient android:startColor="#ffdd00"
android:endColor="@color/colorPrimary"
android:centerColor="#ffff" />
<corners android:radius="33dp"/>
<padding
android:bottom="7dp"
android:left="7dp"
android:right="7dp"
android:top="7dp"
/>
Setting CommandTimeout to 120 is not recommended. Try using pagination as mentioned above. Setting CommandTimeout to 30 is considered as normal. Anything more than that is consider bad approach and that usually concludes something wrong with the Implementation. Now the world is running on MiliSeconds Approach.
Create an init() function and point the table layout. Then create the needed rows and columns.
public void init() {
TableLayout stk = (TableLayout) findViewById(R.id.table_main);
TableRow tbrow0 = new TableRow(this);
TextView tv0 = new TextView(this);
tv0.setText(" Sl.No ");
tv0.setTextColor(Color.WHITE);
tbrow0.addView(tv0);
TextView tv1 = new TextView(this);
tv1.setText(" Product ");
tv1.setTextColor(Color.WHITE);
tbrow0.addView(tv1);
TextView tv2 = new TextView(this);
tv2.setText(" Unit Price ");
tv2.setTextColor(Color.WHITE);
tbrow0.addView(tv2);
TextView tv3 = new TextView(this);
tv3.setText(" Stock Remaining ");
tv3.setTextColor(Color.WHITE);
tbrow0.addView(tv3);
stk.addView(tbrow0);
for (int i = 0; i < 25; i++) {
TableRow tbrow = new TableRow(this);
TextView t1v = new TextView(this);
t1v.setText("" + i);
t1v.setTextColor(Color.WHITE);
t1v.setGravity(Gravity.CENTER);
tbrow.addView(t1v);
TextView t2v = new TextView(this);
t2v.setText("Product " + i);
t2v.setTextColor(Color.WHITE);
t2v.setGravity(Gravity.CENTER);
tbrow.addView(t2v);
TextView t3v = new TextView(this);
t3v.setText("Rs." + i);
t3v.setTextColor(Color.WHITE);
t3v.setGravity(Gravity.CENTER);
tbrow.addView(t3v);
TextView t4v = new TextView(this);
t4v.setText("" + i * 15 / 32 * 10);
t4v.setTextColor(Color.WHITE);
t4v.setGravity(Gravity.CENTER);
tbrow.addView(t4v);
stk.addView(tbrow);
}
}
Call init function in your onCreate method:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
init();
}
Layout file like:
<ScrollView
android:id="@+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#3d455b"
android:layout_alignParentLeft="true" >
<HorizontalScrollView
android:id="@+id/hscrll1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<RelativeLayout
android:id="@+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_gravity="center"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TableLayout
android:id="@+id/table_main"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" >
</TableLayout>
</RelativeLayout>
</HorizontalScrollView>
</ScrollView>
Will look like:
Where you've written "OffenceBox.Text()", you need to replace this with "OffenceBox.Text". It's a property, not a method - the clue's in the error!
Without using any custom classes or libraries:
<ImageView
android:id="@id/img"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitCenter" />
scaleType="fitCenter"
(default when omitted)
scaleType="centerInside"
src
is smaller than parent widthsrc
is larger than parent widthIt doesn't matter if you use android:src
or ImageView.setImage*
methods and the key is probably the adjustViewBounds
.
android:gravity
can be used on a Layout to align its children.
android:layout_gravity
can be used on any view to align itself in its parent.
NOTE: If self or children is not centering as expected, check if width/height is
match_parent
and change to something else
private void mainForm_FormClosing(object sender, FormClosingEventArgs e)
{
if (MessageBox.Show("This will close down the whole application. Confirm?", "Close Application", MessageBoxButtons.YesNo) == DialogResult.Yes)
{
MessageBox.Show("The application has been closed successfully.", "Application Closed!", MessageBoxButtons.OK);
System.Windows.Forms.Application.Exit();
}
else
{
this.Activate();
}
}
I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.
I wasn't using Azure, but I got the same error locally. Using <customErrors mode="Off" />
seemed to have no effect, but checking the Application logs in Event Viewer revealed a warning from ASP.NET which contained all the detail I needed to resolve the issue.
Try:
SqlConnection myConnection = new SqlConnection("Database=testDB;Server=Paul-PC\\SQLEXPRESS;Integrated Security=True;connect timeout = 30");
It works for me:
File imgFile = new File("/sdcard/Images/test_image.jpg");
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
//Drawable d = new BitmapDrawable(getResources(), myBitmap);
ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);
myImage.setImageBitmap(myBitmap);
}
Edit:
If above hard-coded sdcard directory is not working in your case, you can fetch the sdcard path:
String sdcardPath = Environment.getExternalStorageDirectory().toString();
File imgFile = new File(sdcardPath);
Things seems a little confused in the code in your question, so I am going to give you an example of what I think you are try to do.
First considerations are about mixing HTML, Javascript and CSS:
Why is using onClick() in HTML a bad practice?
I will be removing inline content and splitting these into their appropriate files.
Next, I am going to go with the "click" event and displose of the "change" event, as it is not clear that you want or need both.
Your function changeBackground
sets both the backround color and the text color to the same value (your text will not be seen), so I am caching the color value as we don't need to look it up in the DOM twice.
CSS
#TheForm {
margin-left: 396px;
}
#submitColor {
margin-left: 48px;
margin-top: 5px;
}
HTML
<form id="TheForm">
<input id="color" type="text" />
<br/>
<input id="submitColor" value="Submit" type="button" />
</form>
<span id="coltext">This text should have the same color as you put in the text box</span>
Javascript
function changeBackground() {
var color = document.getElementById("color").value; // cached
// The working function for changing background color.
document.bgColor = color;
// The code I'd like to use for changing the text simultaneously - however it does not work.
document.getElementById("coltext").style.color = color;
}
document.getElementById("submitColor").addEventListener("click", changeBackground, false);

CSS colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF).
Hex values are written as 3 double digit numbers, starting with a # sign.
Update: as pointed out by @Ian
Hex can be either 3 or 6 characters long
Source: W3C
The format of an RGB value in hexadecimal notation is a ‘#’ immediately followed by either three or six hexadecimal characters. The three-digit RGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This ensures that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the display.
Here is an alternative function that will check that your input is a valid CSS Hex Color, it will set the text color only or throw an alert if it is not valid.
For regex testing, I will use this pattern
/^#(?:[0-9a-f]{3}){1,2}$/i
but if you were regex matching and wanted to break the numbers into groups then you would require a different pattern
function changeBackground() {
var color = document.getElementById("color").value.trim(),
rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i;
if (rxValidHex.test(color)) {
document.getElementById("coltext").style.color = color;
} else {
alert("Invalid CSS Hex Color");
}
}
document.getElementById("submitColor").addEventListener("click", changeBackground, false);
On jsfiddle
Here is a further modification that will allow colours by name along with by hex.
function changeBackground() {
var names = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond", "Blue", "BlueViolet", "Brown", "BurlyWood", "CadetBlue", "Chartreuse", "Chocolate", "Coral", "CornflowerBlue", "Cornsilk", "Crimson", "Cyan", "DarkBlue", "DarkCyan", "DarkGoldenRod", "DarkGray", "DarkGrey", "DarkGreen", "DarkKhaki", "DarkMagenta", "DarkOliveGreen", "Darkorange", "DarkOrchid", "DarkRed", "DarkSalmon", "DarkSeaGreen", "DarkSlateBlue", "DarkSlateGray", "DarkSlateGrey", "DarkTurquoise", "DarkViolet", "DeepPink", "DeepSkyBlue", "DimGray", "DimGrey", "DodgerBlue", "FireBrick", "FloralWhite", "ForestGreen", "Fuchsia", "Gainsboro", "GhostWhite", "Gold", "GoldenRod", "Gray", "Grey", "Green", "GreenYellow", "HoneyDew", "HotPink", "IndianRed", "Indigo", "Ivory", "Khaki", "Lavender", "LavenderBlush", "LawnGreen", "LemonChiffon", "LightBlue", "LightCoral", "LightCyan", "LightGoldenRodYellow", "LightGray", "LightGrey", "LightGreen", "LightPink", "LightSalmon", "LightSeaGreen", "LightSkyBlue", "LightSlateGray", "LightSlateGrey", "LightSteelBlue", "LightYellow", "Lime", "LimeGreen", "Linen", "Magenta", "Maroon", "MediumAquaMarine", "MediumBlue", "MediumOrchid", "MediumPurple", "MediumSeaGreen", "MediumSlateBlue", "MediumSpringGreen", "MediumTurquoise", "MediumVioletRed", "MidnightBlue", "MintCream", "MistyRose", "Moccasin", "NavajoWhite", "Navy", "OldLace", "Olive", "OliveDrab", "Orange", "OrangeRed", "Orchid", "PaleGoldenRod", "PaleGreen", "PaleTurquoise", "PaleVioletRed", "PapayaWhip", "PeachPuff", "Peru", "Pink", "Plum", "PowderBlue", "Purple", "Red", "RosyBrown", "RoyalBlue", "SaddleBrown", "Salmon", "SandyBrown", "SeaGreen", "SeaShell", "Sienna", "Silver", "SkyBlue", "SlateBlue", "SlateGray", "SlateGrey", "Snow", "SpringGreen", "SteelBlue", "Tan", "Teal", "Thistle", "Tomato", "Turquoise", "Violet", "Wheat", "White", "WhiteSmoke", "Yellow", "YellowGreen"],
color = document.getElementById("color").value.trim(),
rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i,
formattedName = color.charAt(0).toUpperCase() + color.slice(1).toLowerCase();
if (names.indexOf(formattedName) !== -1 || rxValidHex.test(color)) {

If you are looking for the amount of time that the associated thread has spent running code inside the application.
You can use ProcessThread.UserProcessorTime
Property which you can get under System.Diagnostics
namespace.
TimeSpan startTime= Process.GetCurrentProcess().Threads[i].UserProcessorTime; // i being your thread number, make it 0 for main
//Write your function here
TimeSpan duration = Process.GetCurrentProcess().Threads[i].UserProcessorTime.Subtract(startTime);
Console.WriteLine($"Time caluclated by CurrentProcess method: {duration.TotalSeconds}"); // This syntax works only with C# 6.0 and above
Note: If you are using multi threads, you can calculate the time of each thread individually and sum it up for calculating the total duration.
The problem you are having is the query command is taking too long. I believe that the default timeout for a query to execute is 15 seconds. You need to set the CommandTimeout (in seconds) so that it is long enough for the command to complete its execution. The "CommandTimeout" is different than the "Connection Timeout" in your connection string and must be set for each command.
In your sql Selecting Event, use the command:
e.Command.CommandTimeout = 60
for example:
Protected Sub SqlDataSource1_Selecting(sender As Object, e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs)
e.Command.CommandTimeout = 60
End Sub
Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.
Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .
if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .
if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .
after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).
if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.
If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.
If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.
If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.
if you further face any difficulty then you need to provide more information about your web site and sql server .
I too needed a rounded ImageView, I used the below code, you can modify it accordingly:
import android.content.Context;

import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;
public class RoundedImageView extends ImageView {
public RoundedImageView(Context context) {
super(context);
}
public RoundedImageView(Context context, AttributeSet attrs) {

You can pass the window to your ViewModel using the CommandParameter
. See my Example below.
I've implemented an CloseWindow
Method which takes a Windows as parameter and closes it. The window is passed to the ViewModel via CommandParameter
. Note that you need to define an x:Name
for the window which should be close. In my XAML Window i call this method via Command
and pass the window itself as a parameter to the ViewModel using CommandParameter
.
Command="{Binding CloseWindowCommand, Mode=OneWay}"
CommandParameter="{Binding ElementName=TestWindow}"
ViewModel
public RelayCommand<Window> CloseWindowCommand { get; private set; }
public MainViewModel()
{
this.CloseWindowCommand = new RelayCommand<Window>(this.CloseWindow);
}
private void CloseWindow(Window window)
{
if (window != null)
{
window.Close();
}
}
View
<Window x:Class="ClientLibTestTool.ErrorView"
x:Name="TestWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:localization="clr-namespace:ClientLibTestTool.ViewLanguages"
DataContext="{Binding Main, Source={StaticResource Locator}}"

Note that i'm using the MVVM light framework, but the principal applies to every wpf application.
This solution violates of the MVVM pattern, because the view-model shouldn't know anything about the UI Implementation. If you want to strictly follow the MVVM programming paradigm you have to abstract the type of the view with an interface.
MVVM conform solution (Former EDIT2)
the user Crono mentions a valid point in the comment section:
Passing the Window object to the view model breaks the MVVM pattern IMHO, because it forces your vm to know what it's being viewed in.
You can fix this by introducing an interface containing a close method.
Interface:
public interface ICloseable
{
void Close();
}
Your refactored ViewModel will look like this:
ViewModel
public RelayCommand<ICloseable> CloseWindowCommand { get; private set; }
public MainViewModel()
{
this.CloseWindowCommand = new RelayCommand<IClosable>(this.CloseWindow);
}
private void CloseWindow(ICloseable window)
{
if (window != null)
{
window.Close();
}
}
You have to reference and implement the ICloseable
interface in your view
View (Code behind)
public partial class MainWindow : Window, ICloseable
{
public MainWindow()
{
InitializeComponent();
}
}
Answer to the original question: (former EDIT1)
Your Login Button (Added CommandParameter):
<Button Name="btnLogin" IsDefault="True" Content="Login" Command="{Binding ShowLoginCommand}" CommandParameter="{Binding ElementName=LoginWindow}"/>
Your code:
public RelayCommand<Window> CloseWindowCommand { get; private set; } // the <Window> is important for your solution!
public MainViewModel()
{
//initialize the CloseWindowCommand. Again, mind the <Window>
//you don't have to do this in your constructor but it is good practice, thought
this.CloseWindowCommand = new RelayCommand<Window>(this.CloseWindow);
}
public bool CheckLogin(Window loginWindow) //Added loginWindow Parameter
{
var user = context.Users.Where(i => i.Username == this.Username).SingleOrDefault();
if (user == null)
{
MessageBox.Show("Unable to Login, incorrect credentials.");
return false;
}
else if (this.Username == user.Username || this.Password.ToString() == user.Password)
{
MessageBox.Show("Welcome "+ user.Username + ", you have successfully logged in.");
this.CloseWindow(loginWindow); //Added call to CloseWindow Method
return true;
}
else
{
MessageBox.Show("Unable to Login, incorrect credentials.");
return false;
}
}
//Added CloseWindow Method
private void CloseWindow(Window window)
{
if (window != null)
{
window.Close();
}
}
using System.IO;
this next code contains 2 methods of reading the text, the first will read single lines and stores them in a string variable, the second one reads the whole text and saves it in a string variable(including "\n" (enters))
both should be quite easy to understand and use.
string pathToFile = "";//to save the location of the selected object
private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
OpenFileDialog theDialog = new OpenFileDialog();
theDialog.Title = "Open Text File";
theDialog.Filter = "TXT files|*.txt";
theDialog.InitialDirectory = @"C:\";
if (theDialog.ShowDialog() == DialogResult.OK)
{
MessageBox.Show(theDialog.FileName.ToString());
pathToFile = theDialog.FileName;//doesn't need .tostring because .filename returns a string// saves the location of the selected object
}
if (File.Exists(pathToFile))// only executes if the file at pathtofile exists//you need to add the using System.IO reference at the top of te code to use this
{
//method1
string firstLine = File.ReadAllLines(pathToFile).Skip(0).Take(1).First();//selects first line of the file
string secondLine = File.ReadAllLines(pathToFile).Skip(1).Take(1).First();
//method2
string text = "";
using(StreamReader sr =new StreamReader(pathToFile))
{
text = sr.ReadToEnd();//all text wil be saved in text enters are also saved
}
}
}
To split the text you can use .Split(" ") and use a loop to put the name back into one string. if you don't want to use .Split() then you could also use foreach and ad an if statement to split it where needed.
to add the data to your class you can use the constructor to add the data like:
public Employee(int EMPLOYEENUM, string NAME, string ADRESS, double WAGE, double HOURS)
{
EmployeeNum = EMPLOYEENUM;
Name = NAME;
Address = ADRESS;
Wage = WAGE;
Hours = HOURS;
}
or you can add it using the set by typing .variablename after the name of the instance(if they are public and have a set this will work). to read the data you can use the get by typing .variablename after the name of the instance(if they are public and have a get this will work).
Take a look at the write.csv
or the write.table
functions. You just have to supply the file name the user selects to the file
parameter, and the dataframe to the x
parameter:
write.csv(x=df, file="myFileName")
You can take the SelectedItem
and cast it back to your class
and access its properties
.
MessageBox.Show(((ComboboxItem)ComboBox_Countries_In_Silvers.SelectedItem).Value);
Edit You can try using DataTextField and DataValueField, I used it with DataSource.
ComboBox_Servers.DataTextField = "Text";
ComboBox_Servers.DataValueField = "Value";
for refresh data gridview in any where you just need this code:
datagridview1.DataSource = "your DataSource";
datagridview1.Refresh();
Click "view details" to find the inner exception.
No need for a StringBuilder
:
string path = @"c:\hereIAm.txt";
if (!File.Exists(path))
{
// Create a file to write to.
using (StreamWriter sw = File.CreateText(path))
{
sw.WriteLine("Here");
sw.WriteLine("I");
sw.WriteLine("am.");
}
}
But of course you can use the StringBuilder
to create all lines and write them to the file at once.
sw.Write(stringBuilder.ToString());
StreamWriter.Write
Method (String) (.NET Framework 1.1)
I am doing this on click of Button.
private static final int CAMERA_PIC_REQUEST = 1;
private View.OnClickListener OpenCamera=new View.OnClickListener() {
@Override
public void onClick(View paramView) {
// TODO Auto-generated method stub
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
NewSelectedImageURL=null;
//outfile where we are thinking of saving it
Date date = new Date();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss");
String newPicFile = RecipeName+ df.format(date) + ".png";
String outPath =Environment.getExternalStorageDirectory() + "/myFolderName/"+ newPicFile ;
File outFile = new File(outPath);
CapturedImageURL=outFile.toString();
Uri outuri = Uri.fromFile(outFile);
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, outuri);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
};
You can get the URL of the recently Captured Image from variable CapturedImageURL
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//////////////////////////////////////
if (requestCode == CAMERA_PIC_REQUEST) {
// do something
if (resultCode == RESULT_OK)
{
Uri uri = null;
if (data != null)
{
uri = data.getData();
}
if (uri == null && CapturedImageURL != null)
{
uri = Uri.fromFile(new File(CapturedImageURL));
}
File file = new File(CapturedImageURL);
if (!file.exists()) {
file.mkdir();
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+Environment.getExternalStorageDirectory())));
}
}
}
There is a library named Picasso which can efficiently load images from a URL. It can also load an image from a file.
Examples:
Load URL into ImageView without generating a bitmap:
Picasso.with(context) // Context
.load("http://abc.imgur.com/gxsg.png") // URL or file
.into(imageView); // An ImageView object to show the loaded image
Load URL into ImageView by generating a bitmap:
Picasso.with(this)
.load(artistImageUrl)
.into(new Target() {
@Override
public void onBitmapLoaded(final Bitmap bitmap, Picasso.LoadedFrom from) {
/* Save the bitmap or do something with it here */
// Set it in the ImageView
theView.setImageBitmap(bitmap)
}
@Override
public void onBitmapFailed(Drawable errorDrawable) {
}
@Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
}
});
There are many more options available in Picasso. Here is the documentation.

I recently found out by accident that since you have more control on a ImageView that you can set an onclicklistener for an image here is a sample of a dynamically created image button
private int id;
private bitmap bmp;
LinearLayout.LayoutParams familyimagelayout = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT );
final ImageView familyimage = new ImageView(this);
familyimage.setBackground(null);
familyimage.setImageBitmap(bmp);
familyimage.setScaleType(ImageView.ScaleType.FIT_START);
familyimage.setAdjustViewBounds(true);
familyimage.setId(id);
familyimage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//what you want to do put here
}
});
Beyond the problematic use of async
as pointed out by @Servy, the other issue is that you need to explicitly get T
from Task<T>
by calling Task.Result. Note that the Result property will block async code, and should be used carefully.
Try:
private async void button1_Click(object sender, EventArgs e)
{
var s = await methodAsync();
MessageBox.Show(s.Result);
}
If you don't mind muddying your references a bit, you can include Microsoft.Visualbasic,
and use this very short way.
Display the MessageBox
(new System.Threading.Thread(CloseIt)).Start();
MessageBox.Show("HI");
CloseIt Function:
public void CloseIt()
{
System.Threading.Thread.Sleep(2000);
Microsoft.VisualBasic.Interaction.AppActivate(
System.Diagnostics.Process.GetCurrentProcess().Id);
System.Windows.Forms.SendKeys.SendWait(" ");
}
Now go wash your hands!
There is not official api support which means that it is not documented for the public and the libraries may change at any time. I realize you don't want to leave the application but here's how you do it with an intent for anyone else wondering.
public void sendData(int num){
String fileString = "..."; //put the location of the file here
Intent mmsIntent = new Intent(Intent.ACTION_SEND);
mmsIntent.putExtra("sms_body", "text");
mmsIntent.putExtra("address", num);
mmsIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(fileString)));
mmsIntent.setType("image/jpeg");
startActivity(Intent.createChooser(mmsIntent, "Send"));
}
I haven't completely figured out how to do things like track the delivery of the message but this should get it sent.
You can be alerted to the receipt of mms the same way as sms. The intent filter on the receiver should look like this.
<intent-filter>
<action android:name="android.provider.Telephony.WAP_PUSH_RECEIVED" />
<data android:mimeType="application/vnd.wap.mms-message" />
</intent-filter>
If you try to call requestFocus()
before layout is inflated, it will return false. This code runs after layout get inflated. You don't need 200 ms delay as mentioned above.
editText.post(Runnable {
if(editText.requestFocus()) {
val imm = editText.context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager?
imm?.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0)
}
})
you can use something like this :
string [] filePaths = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories);
instead of using "." you can type the name of the file or just the type like "*.txt" also SearchOption.AllDirectories is to search in all subfolders you can change that if you only want one level more about how to use it on here
Just a speculation, I have not enough experience to try it... )-:
Since GoogleMap is a fragment, it should be possible to catch marker onClick event and show custom fragment view. A map fragment will be still visible on the background. Does anybody tried it? Any reason why it could not work?
The disadvantage is that map fragment would be freezed on backgroud, until a custom info fragment return control to it.
Your TextView Attributes need to be something like,
<TextView ...
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical|right" ../>
Now, Description why these need to be done,
android:layout_width="match_parent"
android:layout_height="match_parent"
Makes your TextView to match_parent
or fill_parent
if You don't want to be it like, match_parent
you have to give some specified values to layout_height
so it get space for vertical center gravity. android:layout_width="match_parent"
necessary because it align your TextView in Right side so you can recognize respect to Parent Layout of TextView.
Now, its about android:gravity
which makes the content of Your TextView alignment. android:layout_gravity
makes alignment of TextView respected to its Parent Layout.
Update:
As below comment says use fill_parent
instead of match_parent
. (Problem in some device.)
This maybe goes without saying but always remember that you can handle some of these image handling issues on your server. I used responses like the ones contained in this thread to handle the immediate display of the image. However my application requires images to be stored on the server (this is probably a common requirement if you want the image to persist as users switch phones).
The solutions contained in many of the threads concerning this topic don't discuss the lack of persistence of the EXIF data which doesn't survive the Bitmap's image compression, meaning you'll need to rotate the image each time your server loads it. Alternatively, you can send the EXIF orientation data to your server, and then rotate the image there if needed.
It was easier for me to create a permanent solution on a server because I didn't have to worry about Android's clandestine file paths.
Observer a.k.a callback is registered at Observable.
It is used for informing e.g. about events that happened at some point of time. It is widely used in Swing, Ajax, GWT for dispatching operations on e.g. UI events (button clicks, textfields changed etc).
In Swing you find methods like addXXXListener(Listener l), in GWT you have (Async)callbacks.
As list of observers is dynamic, observers can register and unregister during runtime. It is also a good way do decouple observable from observers, as interfaces are used.
Including this in the read.csv
command worked for me: strip.white = TRUE
(I found this solution here.)
This will work, make sure your control Event is assigned to this code, it has probably been lost, I also noticed that Double click will only work if the cell is not empty. Try double clicking on a cell with content, don't mess with the designer
private void dgvReport_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
{
//do something
}
If you came here because your VSTS build job is failing with the above error message. Ensure that you are using at least version 2.* of the nuget task to restore your packages.
Fairly old question but incase someone goes back.
This isn't as compact as the other answers above, but fairly readable and easier to type using Visual Studio Multi-Line selection shortcut [Alt+ Shift + ?] (or other directions)
string Camnr = string.Empty;
string Klantnr = string.Empty;
Type out all variable names on new lines. Multi-Select in front of them an type "string". Multi-Select behind them and type "= string.Empty;".
This can also be done in the following way:
JObject data = JObject.Parse(File.ReadAllText(MyFilePath));
Filter the data directly from DataTable
or Dataset
:
"MyTable".DefaultView.RowFilter = "<DataTable Field> LIKE '%" + textBox1.Text + "%'";
this.dataGridView1.DataSource = "MyTable".DefaultView;
Use this code on event KeyUp
of Textbox
, replace "MyTable" for you table name or dataset, replace for the field where you want make the search.
I'm a little late, but, since some time ago in TypeScript you can define the type of callback with
type MyCallback = (KeyboardEvent) => void;
Example of use:
this.addEvent(document, "keydown", (e) => {
if (e.keyCode === 1) {
e.preventDefault();
}
});
addEvent(element, eventName, callback: MyCallback) {
element.addEventListener(eventName, callback, false);
}
Python equivalent code for a QMessageBox which consist of a question in it and Yes and No button. When Yes Button is clicked it will pop up another message box saying yes is clicked and same for No button also. You can push your own code after if block.
button_reply = QMessageBox.question(self,"Test", "Are you sure want to quit??", QMessageBox.Yes,QMessageBox.No,)
if button_reply == QMessageBox.Yes:
QMessageBox.information(self, "Test", "Yes Button Was Clicked")
else :
QMessageBox.information(self, "Test", "No Button Was Clicked")
I would either one of the following:
Application.Exit();
for a winform or
Environment.Exit(0);
for a console application (works on winforms too).
Thanks!
REPLACE(<your xml column>,'&',chr(38)||'amp;')
There's no way to evaluate multiple values in one 'case'. You could either use an if statement (as others have suggested) or call a method which evaluates the range that the integer belongs to and returns a value which represents that range (such as "minor", "adult", etc.), then evaluate this returned value in the switch statement. Of course, you'd probably still be using an if statement in the custom method.
You would still need to go through the DataTable
class. But you can do so using your DataRow
instance by using the Table
property.
foreach (DataColumn c in dr.Table.Columns) //loop through the columns.
{
MessageBox.Show(c.ColumnName);
}
You will have to completely re-write your code. DisplayMember and ValueMember point to columnNames! Furthermore you should really use a using block
- so the connection gets disposed (and closed) after query execution.
Instead of using a dataReader to access the values I choosed a dataTable and bound it as dataSource onto the comboBox.
using (SqlConnection conn = new SqlConnection(@"Data Source=SHARKAWY;Initial Catalog=Booking;Persist Security Info=True;User ID=sa;Password=123456"))
{
try
{
string query = "select FleetName, FleetID from fleets";
SqlDataAdapter da = new SqlDataAdapter(query, conn);
conn.Open();
DataSet ds = new DataSet();
da.Fill(ds, "Fleet");
cmbTripName.DisplayMember = "FleetName";
cmbTripName.ValueMember = "FleetID";
cmbTripName.DataSource = ds.Tables["Fleet"];
}
catch (Exception ex)
{
// write exception info to log or anything else
MessageBox.Show("Error occured!");
}
}
Using a dataTable may be a little bit slower than a dataReader but I do not have to create my own class. If you really have to/want to make use of a DataReader you may choose @Nattrass approach. In any case you should write a using block!
EDIT
If you want to get the current Value of the combobox try this
private void cmbTripName_SelectedIndexChanged(object sender, EventArgs e)
{
if (cmbTripName.SelectedItem != null)
{
DataRowView drv = cmbTripName.SelectedItem as DataRowView;
Debug.WriteLine("Item: " + drv.Row["FleetName"].ToString());
Debug.WriteLine("Value: " + drv.Row["FleetID"].ToString());
Debug.WriteLine("Value: " + cmbTripName.SelectedValue.ToString());
}
}
Try to use this :
private void button1_Click(object sender, EventArgs e)
{
for (int i = 0; i < chBoxListTables.Items.Count; i++)
if (chBoxListTables.GetItemCheckState(i) == CheckState.Checked)
{
txtBx.text += chBoxListTables.Items[i].ToString() + " \n";
}
}
private void TextBox1_KeyUp(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
MessageBox.Show("Enter pressed");
}
}
Worked for me.
You have assing button to your imgButton
variable:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imgButton = (Button) findViewById(R.id.imgButton);
imgButton.setOnClickListener(imgButtonHandler);
}
string saveStaff = "INSERT into student (stud_id,stud_name) " + " VALUES ('" + SI+ "', '" + SN + "');";
cmd = new SqlCommand(saveStaff,con);
cmd.ExecuteNonQuery();
You should form the command with the contents of the textboxes:
sql = "insert into Main (Firt Name, Last Name) values(" + textbox2.Text +
"," + textbox3.Text+ ")";
This, of course, provided that you manage to open the connection correctly.
It would be helpful to know what is happening with your current code. If you are getting some error displayed in that message box, it would be great to know what it's saying.
You should also validate the inputs before actually running the command (i.e. make sure they don't contain malicious code).
One thing to check for...
If your class is defined as a typedef:
typedef struct myclass { };
Then you try to refer to it as struct myclass
anywhere else, you'll get Incomplete Type errors left and right. It's sometimes a mistake to forget the class/struct was typedef'ed. If that's the case, remove "struct" from:
typedef struct mystruct {}...
struct mystruct *myvar = value;
Instead use...
mystruct *myvar = value;
Common mistake.
It seems that in VBA macro code for an ActiveX checkbox control you use
If (ActiveSheet.OLEObjects("CheckBox1").Object.Value = True)
and for a Form checkbox control you use
If (ActiveSheet.Shapes("CheckBox1").OLEFormat.Object.Value = 1)
Less no longer evaluates expression inside calc
by default since v3.00
.
Original answer (Less v1.x...2.x
):
Do this:
body { width: calc(~"100% - 250px - 1.5em"); }
In Less 1.4.0 we will have a strictMaths
option which requires all Less calculations to be within brackets, so the calc
will work "out-of-the-box". This is an option since it is a major breaking change. Early betas of 1.4.0 had this option on by default. The release version has it off by default.
OnClick is triggered when the user releases the button. But if you still want to use the TouchListener you need to add it in code. It's just:
myView.setOnTouchListener(new View.OnTouchListener()
{
// Implementation;
});
The best way to go about it would be to get a SynchronizationContext
from the UI thread and use it. This class abstracts marshalling calls to other threads, and makes testing easier (in contrast to using WPF's Dispatcher
directly). For example:
class MyViewModel
{
private readonly SynchronizationContext _syncContext;
public MyViewModel()
{
// we assume this ctor is called from the UI thread!
_syncContext = SynchronizationContext.Current;
}
// ...
private void watcher_Changed(object sender, FileSystemEventArgs e)
{
_syncContext.Post(o => DGAddRow(crp.Protocol, ft), null);
}
}
In WPF there is a control named Popup.
Popup myPopup = new Popup();
//(...)
myPopup.IsOpen = true;
This code may be helpful for you.
from tkinter import filedialog
from tkinter import *
root = Tk()
root.withdraw()
folder_selected = filedialog.askdirectory()
Here's a more valid way which also check if your textbox is filled with only blanks.
// When spaces are not allowed
if (string.IsNullOrWhiteSpace(txtBox1.Text) || string.IsNullOrWhiteSpace(txtBox2.Text))
//...give error...
// When spaces are allowed
if (string.IsNullOrEmpty(txtBox1.Text) || string.IsNullOrEmpty(txtBox2.Text))
//...give error...
The edited answer of @Habib.OSU is also fine, this is just another approach.
You should check your designer file. Open Form1.Designer.cs and
find this line: windows Form Designer Generated Code.
Expand this and you will see a lot of code. So check Whether this line is there inside datagridview1 controls if not place it.
this.dataGridView1.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView1_CellClick);
I hope it helps.

This post will be useful to you.
You can reference Microsoft.VisualBasic.dll
.
Then using the code below.
Microsoft.VisualBasic.Interaction.InputBox("Question?","Title","Default Text");
Alternatively, by adding a using
directive allowing for a shorter syntax in your code (which I'd personally prefer).
using Microsoft.VisualBasic;
...
Interaction.InputBox("Question?","Title","Default Text");
Or you can do what Pranay Rana suggests, that's what I would've done too...
DialogResult result = MessageBox.Show("Do you want to save changes?", "Confirmation", MessageBoxButtons.YesNoCancel);
if(result == DialogResult.Yes)
{
//...
}
else if (result == DialogResult.No)
{
//...
}
else
{
//...
}
If you only want to solve the extremely limited set of equations mx + c = y
for positive integer m, c, y
, then this will do:
import re
def solve_linear_equation ( equ ):
"""
Given an input string of the format "3x+2=6", solves for x.
The format must be as shown - no whitespace, no decimal numbers,
no negative numbers.
"""
match = re.match(r"(\d+)x\+(\d+)=(\d+)", equ)
m, c, y = match.groups()
m, c, y = float(m), float(c), float(y) # Convert from strings to numbers
x = (y-c)/m
print ("x = %f" % x)
Some tests:
>>> solve_linear_equation("2x+4=12")
x = 4.000000
>>> solve_linear_equation("123x+456=789")
x = 2.707317
>>>
If you want to recognise and solve arbitrary equations, like sin(x) + e^(i*pi*x) = 1
, then you will need to implement some kind of symbolic maths engine, similar to maxima
, Mathematica
, MATLAB's solve()
or Symbolic Toolbox, etc. As a novice, this is beyond your ken.
Intent ImageIntent = new Intent(Intent.ACTION_PICK,

Uri ImagePathAndName = data.getData();
imgpicture.setImageURI(ImagePathAndName);
I got this same issue when working with Bolts.framework. It turns out that when Bolts gets corrupted, no amount of re-importing will fix the issue. I had to go back to the original download file and reimport it completely from scratch. This fixed it right away. It was such a weird issue that it took me forever to figure it out... hopefully this tip will spare some of you from the same frustrations :)

I've used HttpClient in .NET 4.0 applications on numerous occasions. If you are familiar with NuGet, you can do an Install-Package Microsoft.Net.Http to add it to your project. See the link below for further details.
I would suggest doing this in a more functional style :P
function CreateMessageboard(BoardMessages) {
var htmlMessageboardString = BoardMessages
.map(function(BoardMessage) {
return MessageToHTMLString(BoardMessage);
})
.join('');
}
Try this
Server:
namespace SocketServer
{
class Program
{
static Socket klient;
static void Main(string[] args)
{
Socket server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPEndPoint endPoint = new IPEndPoint(IPAddress.Any, 8888);
server.Bind(endPoint);
server.Listen(20);
while(true)
{
Console.WriteLine("Waiting...");
klient = server.Accept();
Console.WriteLine("Client connected");
Task t = new Task(ServisClient);
t.Start();
}
}
static void ServisClient()
{
try
{
while (true)
{
byte[] buffer = new byte[64];
Console.WriteLine("Waiting for answer...");
klient.Receive(buffer, 0, buffer.Length, 0);
string message = Encoding.UTF8.GetString(buffer);
Console.WriteLine("Answer: " + message);
string answer = "Actualy date is " + DateTime.Now;
buffer = Encoding.UTF8.GetBytes(answer);
Console.WriteLine("Sending {0}", answer);
klient.Send(buffer);
}
}
catch
{
Console.WriteLine("Disconnected");
}
}
}
}
You can use the root.configure(background='your colour') example:-
import tkinter root=tkiner.Tk() root.configure(background='pink')
A constructor should no have a return type . remove void before each constructor .
Some very basic characteristic of a constructor :
a. Same name as class b. no return type. c. will be called every time an object is made with the class. for eg- in your program if u made two objects of Flow, Flow flow1=new Flow(); Flow flow2=new Flow(); then Flow constructor will be called for 2 times.
d. If you want to call the constructor just for once then declare that as static (static constructor) and dont forget to remove any access modifier from static constructor ..
If the problem is 100% here
EffectSelectorForm effectSelectorForm = new EffectSelectorForm(Effects);
There's only one possible explanation: property/variable "Effects" is not initialized properly... Debug your code to see what you pass to your objects.
EDIT after several hours
There were some problems:
MEF attribute [Import] didn't work as expected, so we replaced it for the time being with a manually populated List<>. While the collection was null, it was causing exceptions later in the code, when the method tried to get the type of the selected item and there was none.
several event handlers weren't wired up to control events
Some problems are still present, but I believe OP's original problem has been fixed. Other problems are not related to this one.
I know this post is old but I want to share my code.
Private Sub txtbox1_TextChanged(sender As Object, e As EventArgs) Handles txtbox1.TextChanged
If txtbox1.Text.Length > 0 Then
If Not IsNumeric(txtbox1.Text) Then
Dim sel As Integer = txtbox1.SelectionStart
txtbox1.Text = txtbox1.Text.Remove(sel - 1, 1)
txtbox1.SelectionStart = sel - 1
End If
End If
End Sub
Here's a simple example that simply returns the last line without need to sort anything from any column:
"SELECT * FROM TableName ORDER BY rowid DESC LIMIT 1;"
And in Kotlin:
tailrec fun Context.activity(): Activity? = when {
this is Activity -> this
else -> (this as? ContextWrapper)?.baseContext?.activity()
}
After much try and study, I was able to figure it out. First, the variable data from Intent will always be null so, therefore, checking for !null
will crash your app so long you are passing a URI to startActivityForResult.Follow the example below.
I will be using Kotlin.
Open the camera intent
fun addBathroomPhoto(){
addbathroomphoto.setOnClickListener{
request_capture_image=2
var takePictureIntent:Intent?
takePictureIntent =Intent(MediaStore.ACTION_IMAGE_CAPTURE)
if(takePictureIntent.resolveActivity(activity?.getPackageManager()) != null){
val photoFile: File? = try {
createImageFile()
} catch (ex: IOException) {
// Error occurred while creating the File
null
}
if (photoFile != null) {
val photoURI: Uri = FileProvider.getUriForFile(
activity!!,
"ogavenue.ng.hotelroomkeeping.fileprovider",photoFile)
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
photoURI);
startActivityForResult(takePictureIntent,
request_capture_image);
}
}
}
}`
Create the createImageFile().But you MUST make the imageFilePath variable global. Example on how to create it is on Android official documentation and pretty straightforward
Get Intent
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (requestCode == 1 && resultCode == RESULT_OK) {
add_room_photo_txt.text=""
var myBitmap=BitmapFactory.decodeFile(imageFilePath)
addroomphoto.setImageBitmap(myBitmap)
var file=File(imageFilePath)
var fis=FileInputStream(file)
var bm = BitmapFactory.decodeStream(fis);
roomphoto=getBytesFromBitmap(bm) }}
The getBytesFromBitmap method
fun getBytesFromBitmap(bitmap:Bitmap):ByteArray{
var stream=ByteArrayOutputStream()
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
return stream.toByteArray();
}
I hope this helps.
Use OnCommand event of imagebutton. Within it do
<asp:Button id="Button1" Text="Click" CommandName="Something" CommandArgument="your command arg" OnCommand="CommandBtn_Click" runat="server"/>
Code-behind:
void CommandBtn_Click(Object sender, CommandEventArgs e)
{
switch(e.CommandName)
{
case "Something":
// Do your code
break;
default:
break;
}
}
You need to do it on the UI thread. Use:
Dispatcher.BeginInvoke(new Action(() => {GetGridData(null, 0)}));
Just want to give one example why we decided to store image in DB not files or CDN, it is storing images of signatures.
We have tried to do so via CDN, cloud storage, files, and finally decided to store in DB and happy about the decision as it was proven us right in our subsequent events when we moved, upgraded our scripts and migrated the sites serveral times.
For my case, we wanted the signatures to be with the records that belong to the author of documents.
Storing in files format risks missing them or deleted by accident.
We store it as a blob binary format in MySQL, and later as based64 encoded image in a text field. The decision to change to based64 was due to smaller size as result for some reason, and faster loading. Blob was slowing down the page load for some reason.
In our case, this solution to store signature images in DB, (whether as blob or based64), was driven by:
AC
Here's a method that I just wrote today, so that I can pass as many message boxes to the page as I want to:
/// <summary>
/// Shows a basic MessageBox on the passed in page
/// </summary>
/// <param name="page">The Page object to show the message on</param>
/// <param name="message">The message to show</param>
/// <returns></returns>
public static ShowMessageBox(Page page, string message)
{
Type cstype = page.GetType();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = page.ClientScript;
// Find the first unregistered script number
int ScriptNumber = 0;
bool ScriptRegistered = false;
do
{
ScriptNumber++;
ScriptRegistered = cs.IsStartupScriptRegistered(cstype, "PopupScript" + ScriptNumber);
} while (ScriptRegistered == true);
//Execute the new script number that we found
cs.RegisterStartupScript(cstype, "PopupScript" + ScriptNumber, "alert('" + message + "');", true);
}
I could not restart IIexpress. This is the solution that worked for me
A console application does not automatically add a reference to System.Windows.Forms.dll.
Right-click your project in Solution Explorer and select Add reference... and then find System.Windows.Forms and add it.
You're right that you should use the Dispatcher
to update controls on the UI thread, and also right that long-running processes should not run on the UI thread. Even if you run the long-running process asynchronously on the UI thread, it can still cause performance issues.
It should be noted that Dispatcher.CurrentDispatcher
will return the dispatcher for the current thread, not necessarily the UI thread. I think you can use Application.Current.Dispatcher
to get a reference to the UI thread's dispatcher if that's available to you, but if not you'll have to pass the UI dispatcher in to your background thread.
Typically I use the Task Parallel Library for threading operations instead of a BackgroundWorker
. I just find it easier to use.
For example,
Task.Factory.StartNew(() =>
SomeObject.RunLongProcess(someDataObject));
where
void RunLongProcess(SomeViewModel someDataObject)
{
for (int i = 0; i <= 1000; i++)
{
Thread.Sleep(10);
// Update every 10 executions
if (i % 10 == 0)
{
// Send message to UI thread
Application.Current.Dispatcher.BeginInvoke(
DispatcherPriority.Normal,
(Action)(() => someDataObject.ProgressValue = (i / 1000)));
}
}
}
private void DeleteProductButton_Click(object sender, EventArgs e)
{
string ProductID = deleteProductButton.Text;
if (string.IsNullOrEmpty(ProductID))
{
MessageBox.Show("Please enter valid ProductID");
deleteProductButton.Focus();
}
try
{
string SelectDelete = "Delete from Products where ProductID=" + deleteProductButton.Text;
SqlCommand command = new SqlCommand(SelectDelete, Conn);
command.CommandType = CommandType.Text;
command.CommandTimeout = 15;
DialogResult comfirmDelete = MessageBox.Show("Are you sure you want to delete this record?");
if (comfirmDelete == DialogResult.No)
{
return;
}
}
catch (Exception Ex)
{
MessageBox.Show(Ex.Message);
}
}
Did you try adding the self prefix to the fileName and replacing the method above the Button ? With the self, it becomes visible between methods.
...
def load_file(self):
self.fileName = filedialog.askopenfilename(filetypes = (("Template files", "*.tplate")
,("HTML files", "*.html;*.htm")
,("All files", "*.*") ))
...
IF(compliment IN('set','Y',1), 'Y', 'N') AS customer_compliment
Will do the job as Buttle Butkus suggested.
Another simple way to rotate an ImageView
:
UPDATE:
Required imports:
import android.graphics.Matrix;
import android.widget.ImageView;
Code: (Assuming imageView
, angle
, pivotX
& pivotY
are already defined)
Matrix matrix = new Matrix();
imageView.setScaleType(ImageView.ScaleType.MATRIX); //required
matrix.postRotate((float) angle, pivotX, pivotY);
imageView.setImageMatrix(matrix);
This method does not require creating a new bitmap each time.
NOTE: To rotate an
ImageView
on ontouch at runtime you can set onTouchListener onImageView
& rotate it by adding last two lines(i.e. postRotate matrix & set it on imageView) in above code section in your touch listener ACTION_MOVE part.
string sqlCon = @"Data Source=.\SQLEXPRESS;" +
@"AttachDbFilename=|DataDirectory|\SampleDB.mdf;
Integrated Security=True;
Connect Timeout=30;
User Instance=True";
SqlConnection Con = new SqlConnection(sqlCon);
The filepath should have |DataDirectory| which actually links to "current project directory\App_Data\" or "current project directory" and get the .mdf file.....Place the .mdf in either of these places and should work in visual studio 2010.And when you use the standalone application on production system, then the current path where the executable file is, should have the .mdf file.
File myFile = new File(uri.toString());
myFile.getAbsolutePath()
should return u the correct path
EDIT
As @Tron suggested the working code is
File myFile = new File(uri.getPath());
myFile.getAbsolutePath()
Based on Aladin Q's solution, here is a helper function that I wrote, that will change the image in an imageview while running a little fade out / fade in animation:
public static void ImageViewAnimatedChange(Context c, final ImageView v, final Bitmap new_image) {
final Animation anim_out = AnimationUtils.loadAnimation(c, android.R.anim.fade_out);
final Animation anim_in = AnimationUtils.loadAnimation(c, android.R.anim.fade_in);
anim_out.setAnimationListener(new AnimationListener()
{
@Override public void onAnimationStart(Animation animation) {}
@Override public void onAnimationRepeat(Animation animation) {}
@Override public void onAnimationEnd(Animation animation)
{
v.setImageBitmap(new_image);
anim_in.setAnimationListener(new AnimationListener() {
@Override public void onAnimationStart(Animation animation) {}
@Override public void onAnimationRepeat(Animation animation) {}
@Override public void onAnimationEnd(Animation animation) {}
});
v.startAnimation(anim_in);
}
});
v.startAnimation(anim_out);
}
As others have noted, "SKU" stands for stock keeping unit. Here's what I find currently (3 February 2017) in the Apple documentation regarding the "SKU Number:"
SKU Number
A unique ID for your app in the Apple system that is not seen by users. You can use letters, numbers, hyphens, periods, and underscores. The SKU can’t
start with a hyphen, period, or underscore. Use a value that is meaningful to your organization. Can’t be edited after saving the iTunes Connect record.
(internet archive link:) iTunes Connect Properties
As has been suggested, using the string.format method is nice and simple and very readable.
In vb.net the " + " is used for addition and the " & " is used for string concatenation.
In your example:
MsgBox("Variable = " + variable)
becomes:
MsgBox("Variable = " & variable)
I may have been a bit quick answering this as it appears these operators can both be used for concatenation, but recommended use is the "&", source http://msdn.microsoft.com/en-us/library/te2585xw(v=VS.100).aspx
maybe call
variable.ToString()
update:
Use string interpolation (vs2015 onwards I believe):
MsgBox($"Variable = {variable}")
Rijndael/AES is a block cypher. It encrypts data in 128 bit (16 character) blocks. Cryptographic padding is used to make sure that the last block of the message is always the correct size.
Your decryption method is expecting whatever its default padding is, and is not finding it. As @NetSquirrel says, you need to explicitly set the padding for both encryption and decryption. Unless you have a reason to do otherwise, use PKCS#7 padding.
For Kotlin Users don't forget to add ? in data: Intent?
like
public override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {}
This will get you a Bitmap
from the ImageView
. Though, it is not the same bitmap object that you've set. It is a new one.
imageView.buildDrawingCache();
Bitmap bitmap = imageView.getDrawingCache();
=== EDIT ===
imageView.setDrawingCacheEnabled(true);
imageView.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
imageView.layout(0, 0,
imageView.getMeasuredWidth(), imageView.getMeasuredHeight());
imageView.buildDrawingCache(true);
Bitmap bitmap = Bitmap.createBitmap(imageView.getDrawingCache());
imageView.setDrawingCacheEnabled(false);
One touch point I found that needs to be put in place is "hidden" away in the Proguard configuration. While the HTML reader invokes through the javascript interface just fine when debugging the app, this works no longer as soon as the app was run through Proguard, unless the HTML reader function is declared in the Proguard config file, like so:
-keepclassmembers class <your.fully.qualified.HTML.reader.classname.here> {
public *;
}
Tested and confirmed on Android 2.3.6, 4.1.1 and 4.2.1.
You can do it using string.indexOf("{item}")
. If the result is greater than -1 {item}
is in the string
@outis's answer is good: concise and correct as regards relations.
However, the situation is slightly more complicated as regards SQL.
Consider the usual suppliers and parts database but implemented in SQL:
SELECT * FROM S NATURAL JOIN SP;
would return a resultset** with columns
SNO, SNAME, STATUS, CITY, PNO, QTY
The join is performed on the column with the same name in both tables, SNO
. Note that the resultset has six columns and only contains one column for SNO
.
Now consider a theta eqijoin, where the column names for the join must be explicitly specified (plus range variables S
and SP
are required):
SELECT * FROM S JOIN SP ON S.SNO = SP.SNO;
The resultset will have seven columns, including two columns for SNO
. The names of the resultset are what the SQL Standard refers to as "implementation dependent" but could look like this:
SNO, SNAME, STATUS, CITY, SNO, PNO, QTY
or perhaps this
S.SNO, SNAME, STATUS, CITY, SP.SNO, PNO, QTY
In other words, NATURAL JOIN
in SQL can be considered to remove columns with duplicated names from the resultset (but alas will not remove duplicate rows - you must remember to change SELECT
to SELECT DISTINCT
yourself).
** I don't quite know what the result of SELECT * FROM table_expression;
is. I know it is not a relation because, among other reasons, it can have columns with duplicate names or a column with no name. I know it is not a set because, among other reasons, the column order is significant. It's not even a SQL table or SQL table expression. I call it a resultset.
You need to close the connection before you can use the output parameters. Something like this
con.Close();
MessageBox.Show(cmd.Parameters["@code"].Value.ToString());
listPaired = (ListView) findViewById( R.id.listView1 );
listPairedData = new ArrayList < String >();
araPaired = new ArrayAdapter( this, android.R.layout.simple_list_item_1, listPairedData );
listPaired.setAdapter( araPaired );
listPaired.setOnItemClickListener( listPairedClickItem );
private OnItemClickListener listPairedClickItem = new OnItemClickListener() {
@Override
public void onItemClick(AdapterView < ? > arg0, View arg1, int arg2, long arg3) {
String info = ( (TextView) arg1 ).getText().toString();
Toast.makeText( getBaseContext(), "Item " + info, Toast.LENGTH_LONG ).show();
}
};
Using MS SQL Server 2008, in DELETE dialog with Close connection options, this is the generated script, I guess it is the best:
EXEC msdb.dbo.sp_delete_database_backuphistory @database_name = N'YOUR_DATABASE_NAME'
GO
USE [master]
GO
ALTER DATABASE [YOUR_DATABASE_NAME] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
GO
USE [master]
GO
/****** Object: Database [YOUR_DATABASE_NAME] Script Date: 01/08/2014 21:36:29 ******/
DROP DATABASE [YOUR_DATABASE_NAME]
GO
based on Sam Holder's answer, you could make an extension method for that
namespace adonet.extensions
{
public static class AdonetExt
{
public static int GetInt32(this SqlDataReader reader, string columnName)
{
return reader.GetInt32(reader.GetOrdinal(columnName));
}
}
}
and use it like this
using adonet.extensions;
//...
int farmsize = reader.GetInt32("farmsize");
assuming there is no GetInt32(string) already in SqlDataReader - if there is any, just use some other method name instead
in the DBAdaper i.e Data Base helper class declare the table like this
private static final String USERDETAILS=
"create table userdetails(usersno integer primary key autoincrement,userid text not null ,username text not null,password text not null,photo BLOB,visibility text not null);";
insert the values like this,
first convert the images as byte[]
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Bitmap bitmap = ((BitmapDrawable)getResources().getDrawable(R.drawable.common)).getBitmap();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] photo = baos.toByteArray();
db.insertUserDetails(value1,value2, value3, photo,value2);
in DEAdaper class
public long insertUserDetails(String uname,String userid, String pass, byte[] photo,String visibility)
{
ContentValues initialValues = new ContentValues();
initialValues.put("username", uname);
initialValues.put("userid",userid);
initialValues.put("password", pass);
initialValues.put("photo",photo);
initialValues.put("visibility",visibility);
return db.insert("userdetails", null, initialValues);
}
retrieve the image as follows
Cursor cur=your query;
while(cur.moveToNext())
{
byte[] photo=cur.getBlob(index of blob cloumn);
}
convert the byte[] into image
ByteArrayInputStream imageStream = new ByteArrayInputStream(photo);
Bitmap theImage= BitmapFactory.decodeStream(imageStream);

JObject.ContainsKey(string propertyName)
has been made as public method in 11.0.1 release
Documentation - https://www.newtonsoft.com/json/help/html/M_Newtonsoft_Json_Linq_JObject_ContainsKey.htm
Simple:

You need to convert your wildcard expression to a regular expression. For example:
private bool WildcardMatch(String s, String wildcard, bool case_sensitive)
{
// Replace the * with an .* and the ? with a dot. Put ^ at the
// beginning and a $ at the end
String pattern = "^" + Regex.Escape(wildcard).Replace(@"\*", ".*").Replace(@"\?", ".") + "$";
// Now, run the Regex as you already know
Regex regex;
if(case_sensitive)
regex = new Regex(pattern);
else
regex = new Regex(pattern, RegexOptions.IgnoreCase);
return(regex.IsMatch(s));
}
Try this:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
ComboBox cmb = (ComboBox)sender;
int selectedIndex = cmb.SelectedIndex;
int selectedValue = (int)cmb.SelectedValue;
ComboboxItem selectedCar = (ComboboxItem)cmb.SelectedItem;
MessageBox.Show(String.Format("Index: [{0}] CarName={1}; Value={2}", selectedIndex, selectedCar.Text, selecteVal));
}

int RowIndex = gvr.RowIndex;
I tried all of the solutions above trying to figure out why one of my unit tests were failing to pick up the configuration from an app.config file that is perfect.
I had 2 references to the same assembly like so:
Removing the (duplicate) reference in yellow fixed it for me.
I hope this works for someone else, it drove me nuts for a while.
I know it's a bit late but, Microsoft has made their Xaml.Behaviors open source and it's now much easier to use interactivity with just one namespace.
Then use it like this,
<Button Width="150" Style="{DynamicResource MaterialDesignRaisedDarkButton}">
<behaviours:Interaction.Triggers>
<behaviours:EventTrigger EventName="Click">
<behaviours:InvokeCommandAction Command="{Binding OpenCommand}" PassEventArgsToCommand="True"/>
</behaviours:EventTrigger>
</behaviours:Interaction.Triggers>
Open
</Button>
PassEventArgsToCommand="True" should be set as True and the RelayCommand that you implement can take RoutedEventArgs or objects as template. If you are using object as the parameter type just cast it to the appropriate event type.
The command will look something like this,
OpenCommand = new RelayCommand<object>(OnOpenClicked, (o) => { return true; });
The command method will look something like this,
private void OnOpenClicked(object parameter)
{
Logger.Info(parameter?.GetType().Name);
}
The 'parameter' will be the Routed event object.
And the log incase you are curious,
2020-12-15 11:40:36.3600|INFO|MyApplication.ViewModels.MainWindowViewModel|RoutedEventArgs
As you can see the TypeName logged is RoutedEventArgs
RelayCommand impelmentation can be found here.
PS : You can bind to any event of any control. Like Closing event of Window and you will get the corresponding events.
Well, you are clearing the textbox right before you check if it's empty
/* !! This clears the textbox BEFORE you check if it's empty */
MaterialTextBox.Clear();
HoursNumericUpDown.Value = HoursNumericUpDown.Minimum;
MarkNumericUpDown.Value = MarkNumericUpDown.Minimum;
if (String.IsNullOrEmpty(MaterialTextBox.Text))
{
MessageBox.Show("Enter Material Name Please.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Warning);
//dataGridView1.Rows.Clear();
}
If you are using nested fragments, this is also working:
getParentFragment().startActivityForResult(intent, RequestCode);
In addition to this, you have to call super.onActivityResult
from parent activity and fill the onActivityResult
method of the fragment.
The key is to set the drawable as the image of the button, not as a background. Like this:
rb.setButtonDrawable(R.drawable.whatever_drawable);
You could create a DataView object from your datasource. This would allow you to filter and sort your data without directly modifying the datasource.
Also, remember to call dataGridView1.DataBind();
after you set the data source.
First you need to set a reference (Menu: Tools->References) to the Microsoft Excel Object Library then you can access all Excel Objects.
After you added the Reference you have full access to all Excel Objects. You need to add Excel in front of everything for example:
Dim xlApp as Excel.Application
Let's say you added an Excel Workbook Object in your Form and named it xLObject.
Here is how you Access a Sheet of this Object and change a Range
Dim sheet As Excel.Worksheet
Set sheet = xlObject.Object.Sheets(1)
sheet.Range("A1") = "Hello World"
(I copied the above from my answer to this question)
Another way to use Excel in Access is to start Excel through a Access Module (the way shahkalpesh described it in his answer)
Sum all cells
double X=0;
if (datagrid.Rows.Count-1 > 0)
{
for(int i = 0; i < datagrid.Rows.Count-1; i++)
{
for(int j = 0; j < datagrid.Rows.Count-1; j++)
{
X+=Convert.ToDouble(datagrid.Rows[i].Cells[j].Value.ToString());
}
}
}
I couldn't figure out how to use the API using the first Google results. Fortunately a thread somewhere pointed me to this link: http://access.mvps.org/access/api/api0049.htm
Which works nicely. :)
System.Diagnostics.Process.Start("c:\\batchfilename.bat");
this simple line will execute the batch file.
Select extract rows from the relation with some condition and Project extract particular number of attribute/column from the relation with or without some condition.
You need to create your own Prompt dialog. You could perhaps create a class for this.
public static class Prompt
{
public static string ShowDialog(string text, string caption)
{
Form prompt = new Form()
{
Width = 500,
Height = 150,
FormBorderStyle = FormBorderStyle.FixedDialog,
Text = caption,
StartPosition = FormStartPosition.CenterScreen
};
Label textLabel = new Label() { Left = 50, Top=20, Text=text };
TextBox textBox = new TextBox() { Left = 50, Top=50, Width=400 };
Button confirmation = new Button() { Text = "Ok", Left=350, Width=100, Top=70, DialogResult = DialogResult.OK };
confirmation.Click += (sender, e) => { prompt.Close(); };
prompt.Controls.Add(textBox);
prompt.Controls.Add(confirmation);
prompt.Controls.Add(textLabel);
prompt.AcceptButton = confirmation;
return prompt.ShowDialog() == DialogResult.OK ? textBox.Text : "";
}
}
And calling it:
string promptValue = Prompt.ShowDialog("Test", "123");
Update:
Added default button (enter key) and initial focus based on comments and another question.
An updated version of the correct answer for .NET 4.5 would be.
if (MessageBox.Show("Are you sure?", "Confirm", MessageBoxImage.Question)
== MessageBoxResult.Yes)
{
// If yes
}
else
{
// If no
}
Additionally, if you wanted to bind the button to a command in a view model you could use the following. This is compatible with MvvmLite:
public RelayCommand ShowPopUpCommand
{
get
{
return _showPopUpCommand ??
(_showPopUpCommand = new RelayCommand(
() =>
{
// Put if statement here
}
}));
}
}
Here is working code for converting an image from a base64 string to an Image
object and storing it in a folder with unique file name:
public void SaveImage()
{
string strm = "R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7";
//this is a simple white background image
var myfilename= string.Format(@"{0}", Guid.NewGuid());
//Generate unique filename
string filepath= "~/UserImages/" + myfilename+ ".jpeg";
var bytess = Convert.FromBase64String(strm);
using (var imageFile = new FileStream(filepath, FileMode.Create))
{
imageFile.Write(bytess, 0, bytess.Length);
imageFile.Flush();
}
}
android:Layout_weight
can be used when you don't attach a fix value to your width already like fill_parent
etc.
Do something like this :
<Button>
Android:layout_width="0dp"
Android:layout_weight=1
-----other parameters
</Button>
I have written a quick example to demonstrate how to create a layout programmatically.
public class CodeLayout extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Creating a new RelativeLayout
RelativeLayout relativeLayout = new RelativeLayout(this);
// Defining the RelativeLayout layout parameters.
// In this case I want to fill its parent
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT);
// Creating a new TextView
TextView tv = new TextView(this);
tv.setText("Test");
// Defining the layout parameters of the TextView
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.CENTER_IN_PARENT);
// Setting the parameters on the TextView
tv.setLayoutParams(lp);
// Adding the TextView to the RelativeLayout as a child
relativeLayout.addView(tv);
// Setting the RelativeLayout as our content view
setContentView(relativeLayout, rlp);
}
}
In theory everything should be clear as it is commented. If you don't understand something just tell me.
If you don't want to expand or collapse all the way - here is a simple HeightAnimation -
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.Transformation;
public class HeightAnimation extends Animation {
protected final int originalHeight;
protected final View view;
protected float perValue;
public HeightAnimation(View view, int fromHeight, int toHeight) {
this.view = view;
this.originalHeight = fromHeight;
this.perValue = (toHeight - fromHeight);
}
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
view.getLayoutParams().height = (int) (originalHeight + perValue * interpolatedTime);
view.requestLayout();
}
@Override
public boolean willChangeBounds() {
return true;
}
}
Usage:
HeightAnimation heightAnim = new HeightAnimation(view, view.getHeight(), viewPager.getHeight() - otherView.getHeight());
heightAnim.setDuration(1000);
view.startAnimation(heightAnim);
Scale a bitmap with a target maximum size and width, while maintaining aspect ratio:
int maxHeight = 2000;
int maxWidth = 2000;
float scale = Math.min(((float)maxHeight / bitmap.getWidth()), ((float)maxWidth / bitmap.getHeight()));
Matrix matrix = new Matrix();
matrix.postScale(scale, scale);
bitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
Try this:
private int hour;
public int Hour
{
get { return hour; }
set
{
//make sure hour is positive
if (value < MIN_HOUR)
{
hour = 0;
MessageBox.Show("Hour value " + value.ToString() + " cannot be negative. Reset to " + MIN_HOUR.ToString(),
"Invalid Hour", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
else
{
//take the modulus to ensure always less than 24 hours
//works even if the value is already within range, or value equal to 24
hour = value % MAX_HOUR;
}
}
}
I would do this the other way round.
In the OnLoad event for your Main form show the Logon form as a dialog. If the dialog result of that is OK then allow Main to continue loading, if the result is authentication failure then abort the load and show the message box.
EDIT Code sample(s)
private void MainForm_Load(object sender, EventArgs e)
{
this.Hide();
LogonForm logon = new LogonForm();
if (logon.ShowDialog() != DialogResult.OK)
{
//Handle authentication failures as necessary, for example:
Application.Exit();
}
else
{
this.Show();
}
}
Another solution would be to show the LogonForm from the Main method in program.cs, something like this:
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
LogonForm logon = new LogonForm();
Application.Run(logon);
if (logon.LogonSuccessful)
{
Application.Run(new MainForm());
}
}
In this example your LogonForm would have to expose out a LogonSuccessful bool property that is set to true when the user has entered valid credentials
what you are trying to do is more a segmentedbutton than an imagebutton list.
here http://blog.bookworm.at/2010/10/segmented-controls-in-android.html is an example on how to do so. The basic idea is to customize RadioButton instead of ImageButton, since the RadioButton will have the checked state you need
yourNode.Toggle();
//use that function on your node, it toggles it
DON'T USE A TRANSAPENT OR NULL LAYOUT because then the button
(or the generic view) will no more highlight at click!!!
I had the same problem and finally I found the correct attribute from Android API to solve the problem. It can apply to any view
Use this in the button specifications
android:background="?android:selectableItemBackground"
This requires API 11
Another MySQL option that may look more like Oracle's DECODE
is a combination of FIELD
and ELT
. In the code that follows, FIELD()
returns the argument list position of the string that matches Age. ELT()
returns the string from ELT
s argument list at the position provided by FIELD()
. For example, if Age
is 14
, FIELD(Age, ...)
returns 2
because 14
is the 2nd argument of FIELD
(not counting Age
). Then, ELT(2, ...)
returns 'Fourteen'
, which is the 2nd argument of ELT
(not counting the FIELD()
argument). IFNULL
returns the default AgeBracket
if no match to Age
is found in the list.
Select Name, IFNULL(ELT(FIELD(Age,
13, 14, 15, 16, 17, 18, 19),'Thirteen','Fourteen','Fifteen','Sixteen',
'Seventeen','Eighteen','Nineteen'),
'Adult') AS AgeBracket
FROM Person
While I don't think this is the best solution to the question either in terms of performance or readability it is interesting as an exploration of MySQL's string functions. Keep in mind that FIELD
's output does not seem to be case sensitive. I.e., FIELD('A','A')
and FIELD('a','A')
both return 1
.
You've probably got Option Strict turned on (which is a good thing), and the compiler is telling you that you can't add a string and an int. Try this:
t = s1 & i.ToString()
I solved this by putting the ImageButton
and TextView
inside a LinearLayout
with vertical orientation. Works great!
<LinearLayout
android:id="@+id/linLayout"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageButton
android:id="@+id/camera_ibtn"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_gravity="center"
android:background="@drawable/camera" />
<TextView
android:id="@+id/textView2"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:gravity="center"
android:text="@string/take_pic"
android:textColor="#FFFFFF"
android:textStyle="bold" />
</LinearLayout>
WinForms
Add an event handler for the Control.DoubleClick
event for your ListBox
, and in that event handler open up a MessageBox
displaying the selected item.
E.g.:
private void ListBox1_DoubleClick(object sender, EventArgs e)
{
if (ListBox1.SelectedItem != null)
{
MessageBox.Show(ListBox1.SelectedItem.ToString());
}
}
Where ListBox1
is the name of your ListBox
.
Note that you would assign the event handler like this:
ListBox1.DoubleClick += new EventHandler(ListBox1_DoubleClick);
WPF
Pretty much the same as above, but you'd use the MouseDoubleClick
event instead:
ListBox1.MouseDoubleClick += new RoutedEventHandler(ListBox1_MouseDoubleClick);
And the event handler:
private void ListBox1_MouseDoubleClick(object sender, RoutedEventArgs e)
{
if (ListBox1.SelectedItem != null)
{
MessageBox.Show(ListBox1.SelectedItem.ToString());
}
}
Edit: Sisya's answer checks to see if the double-click occurred over an item, which would need to be incorporated into this code to fix the issue mentioned in the comments (MessageBox shown if ListBox is double-clicked while an item is selected, but not clicked over an item).
Hope this helps!
import inspect
def s(template, **kwargs):
"Usage: s(string, **locals())"
if not kwargs:
frame = inspect.currentframe()
try:
kwargs = frame.f_back.f_locals
finally:
del frame
if not kwargs:
kwargs = globals()
return template.format(**kwargs)
Usage:
a = 123
s('{a}', locals()) # print '123'
s('{a}') # it is equal to the above statement: print '123'
s('{b}') # raise an KeyError: b variable not found
PS: performance may be a problem. This is useful for local scripts, not for production logs.
Duplicated:
You can use online Minify, it removes these invisible characters efficiently but also changes your code. So be careful.
You can any time switch between type of applications, to console or windows. So, you will not write special logic to see the stdout. Also, when running application in debugger, you will see all the stdout in output window. You might also just add a breakpoint, and in breakpoint properties change "When Hit...", you can output any messages, and variables. Also you can check/uncheck "Continue execution", and your breakpoint will become square shaped. So, the breakpoint messages without changhing anything in the application in the debug output window.
For Visual Studio 2005:
If you do have an installed Visual Studio 2005 however, and want to find out the serial number you’ve used to install it because you don’t have a clue where you put that shiny sticker, you can. It is, like most things in Windows, in the registry.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Registration\PIDKEY
In order to convert the value in that key to an actual serial number you have to put a dash ( – ) after evert 5 characters of the code.
From: http://www.gooli.org/blog/visual-studio-2005-serial-number/
For Visual Studio 2008 it's supposed to be:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Registration\PIDKEY
However I noted that the the Data field for PIDKEY is only filled in the 1000.0x000
(or 2000.0x000) sub folder of the above paths.
This has probably been corrected, but... apparently firefox has a caching problem which is the cause of javascript functions not being recognized.. I really don't know the specifics, but if you clear your cache that will fix the problem (until your cache is full again... not a good solution).. I've been looking around to see if firefox has a real solution to this, but so far nothing... oh not all versions, I think it may be only in some 3.6.x versions, not sure...
https://github.com/adrianmay/rhaboo is a localStorage sugar layer that lets you write things like this:
var store = Rhaboo.persistent('Some name');
store.write('count', store.count ? store.count+1 : 1);
store.write('somethingfancy', {
one: ['man', 'went'],
2: 'mow',
went: [ 2, { mow: ['a', 'meadow' ] }, {} ]
});
store.somethingfancy.went[1].mow.write(1, 'lawn');
It doesn't use JSON.stringify/parse because that would be inaccurate and slow on big objects. Instead, each terminal value has its own localStorage entry.
You can probably guess that I might have something to do with rhaboo.
I ended up using a normal hyperlink along with Url.Action
, as in:
<a href='<%= Url.Action("Show", new { controller = "Browse", id = node.Id }) %>'
data-nodeId='<%= node.Id %>'>
<%: node.Name %>
</a>
It's uglier, but you've got a little more control over the a
tag, which is sometimes useful in heavily AJAXified sites.
HTH
It’s easy; just do the following:
rvm implode
or
rm -rf ~/.rvm
And don’t forget to remove the script calls in the following files:
~/.bashrc
~/.bash_profile
~/.profile
And maybe others depending on whatever shell you’re using.
Postgrseql 9.1 provides for a new command CREATE EXTENSION
. You should use it to install modules.
Modules provided in 9.1 can be found here.. The include,
adminpack , auth_delay , auto_explain , btree_gin , btree_gist
, chkpass , citext , cube , dblink , dict_int
, dict_xsyn , dummy_seclabel , earthdistance , file_fdw , fuzzystrmatch
, hstore , intagg , intarray , isn , lo
, ltree , oid2name , pageinspect , passwordcheck , pg_archivecleanup
, pgbench , pg_buffercache , pgcrypto , pg_freespacemap , pgrowlocks
, pg_standby , pg_stat_statements , pgstattuple , pg_test_fsync , pg_trgm
, pg_upgrade , seg , sepgsql , spi , sslinfo , tablefunc
, test_parser , tsearch2 , unaccent , uuid-ossp , vacuumlo
, xml2
If for instance you wanted to install earthdistance
, simply use this command:
CREATE EXTENSION earthdistance;
If you wanted to install an extension with a hyphen in its name, like uuid-ossp
, you need to enclose the extension name in double quotes:
CREATE EXTENSION "uuid-ossp";
DROP EXTENSION
. You can also get an extension list, and there is basic support for version numbers.I think when everything need a screen to show ( button, dialog,layout...) we have to use context activity, and everything doesn't need a screen to show or process ( toast, service telelphone,contact...) we could use a application context
In my case, resetting ADB didn't make a difference. I also needed to delete my existing virtual devices, which were pretty old, and create new ones.
You can still get not-a-number (NaN) values from simple arithmetic involving inf
:
>>> 0 * float("inf")
nan
Note that you will normally not get an inf
value through usual arithmetic calculations:
>>> 2.0**2
4.0
>>> _**2
16.0
>>> _**2
256.0
>>> _**2
65536.0
>>> _**2
4294967296.0
>>> _**2
1.8446744073709552e+19
>>> _**2
3.4028236692093846e+38
>>> _**2
1.157920892373162e+77
>>> _**2
1.3407807929942597e+154
>>> _**2
Traceback (most recent call last):
File "<stdin>", line 1, in ?
OverflowError: (34, 'Numerical result out of range')
The inf
value is considered a very special value with unusual semantics, so it's better to know about an OverflowError
straight away through an exception, rather than having an inf
value silently injected into your calculations.
Yes, each package must be defined in its own directory.
The source structure is defined in How to Write Go Code.
A package is a component that you can use in more than one program, that you can publish, import, get from an URL, etc. So it makes sense for it to have its own directory as much as a program can have a directory.
Razz's answer is good if you're willing to rewrite what you have done.
Was in the same trouble and worked it out with the following:

Throw it away when Bootstrap comes with a fix for this problem.
MDN suggests that there's a much cleaner way of doing this in modern browsers:
// Assuming we're listening for e.g. a 'change' event on `element`
// Create a new 'change' event
var event = new Event('change');
// Dispatch it.
element.dispatchEvent(event);
Good answers above- if you're looking for something reusable here is the code. Note that you might want to check the decimal places value, and this may overflow.
public static decimal TruncateToDecimalPlace(this decimal numberToTruncate, int decimalPlaces)
{
decimal power = (decimal)(Math.Pow(10.0, (double)decimalPlaces));
return Math.Truncate((power * numberToTruncate)) / power;
}
Addendum
If the branch to which you wish to return was the last checkout that you had made, you can simply use checkout @{-1}
. This will take you back to your previous checkout.
Further, you can alias this command with, for example, git global --config alias.prev
so that you just need to type git prev
to toggle back to the previous checkout.
The first argument to parse() is the expected format. You have to change that to Date.parse("E MMM dd H:m:s z yyyy", testDate)
for it to work. (Note you don't need to create a new Date object, it's a static method)
If you don't know in advance what format, you'll have to find a special parsing library for that. In Ruby there's a library called Chronic, but I'm not aware of a Groovy equivalent. Edit: There is a Java port of the library called jChronic, you might want to check it out.
First, ensure that your version of Eclipse and JDK match, either both 64-bit or both 32-bit (you can't mix-and-match 32-bit with 64-bit).
Second, the -vm argument in eclipse.ini
should point to the java executable. See
http://wiki.eclipse.org/Eclipse.ini for examples.
If you're unsure of what version (64-bit or 32-bit) of Eclipse you have installed, you can determine that a few different ways. See How to find out if an installed Eclipse is 32 or 64 bit version?
just to make the Answer 2 much easier, you can also define the folder where you can put your saved file
spool /home/admin/myoutputfile.txt
select * from table_name;
spool off;
after that only with nano or vi myoutputfile.txt, you will see all the sql track.
hope is that help :)
If you want to assign dynamic bitmap image to bitmap variables
Example for kotlin
backgroundImage = Glide.with(applicationContext).asBitmap().load(PresignedUrl().getUrl(items!![position].img)).into(100, 100).get();
The above answers did not work for me
.asBitmap
should be before the .load("http://....")
I had this problem, understand this isn't what was wrong in the OP's case, but in my case I did have a Startup class, it just wasn't finding it by default.
My problem was the I had spaces in my Assembly Name, and hence the default namespace was different from assembly name, hence the namespace for the startup class was different than the assembly name.
As the error suggests, by convention it looks for [Assembly Name].Startup for the class... so be sure the namespace for your Startup class is the same as the Assembly name. Fixed the problem for me.
you should try this
g++-4.4 -std=c++0x or g++-4.7 -std=c++0x
It's not too hard. Firstly, take a look at FileReader Interface.
So, when the form is submitted, catch the submission process and
var file = document.getElementById('fileBox').files[0]; //Files[0] = 1st file
var reader = new FileReader();
reader.readAsText(file, 'UTF-8');
reader.onload = shipOff;
//reader.onloadstart = ...
//reader.onprogress = ... <-- Allows you to update a progress bar.
//reader.onabort = ...
//reader.onerror = ...
//reader.onloadend = ...
function shipOff(event) {
var result = event.target.result;
var fileName = document.getElementById('fileBox').files[0].name; //Should be 'picture.jpg'
$.post('/myscript.php', { data: result, name: fileName }, continueSubmission);
}
Then, on the server side (i.e. myscript.php):
$data = $_POST['data'];
$fileName = $_POST['name'];
$serverFile = time().$fileName;
$fp = fopen('/uploads/'.$serverFile,'w'); //Prepends timestamp to prevent overwriting
fwrite($fp, $data);
fclose($fp);
$returnData = array( "serverFile" => $serverFile );
echo json_encode($returnData);
Or something like it. I may be mistaken (and if I am, please, correct me), but this should store the file as something like 1287916771myPicture.jpg
in /uploads/
on your server, and respond with a JSON variable (to a continueSubmission()
function) containing the fileName on the server.
Check out fwrite()
and jQuery.post()
.
On the above page it details how to use readAsBinaryString()
, readAsDataUrl()
, and readAsArrayBuffer()
for your other needs (e.g. images, videos, etc).
If you just want to change the color, change the variable (recommended):
@input-border-focus: red;
$input-border-focus: red;
If you wan't to remove it completely, you'll have to overwrite the Mixin that sets the outline.
.form-control-focus(@color: @input-border-focus) {}
If you are using css overwrite it via:
.form-control:focus{
border-color: #cccccc;
-webkit-box-shadow: none;
box-shadow: none;
}
You can also try this: Go to the path where Python is installed in your system. For me it was something like C:\Users\\Local Settings\Application Data\Programs\Python\Python37 In this folder, you'll find a python executable. Just create a duplicate and rename it to python3. Works every time.

'username':'username-value'
});
// sample send broadcast json data for user left
//(I added the following with an event listener for 'beforeunload'):
// socket.emit('user joined', {
// 'userid': 'userid-value',
// 'username':'username-value'
// });
// sample send broadcast json data for any named-event:
socket.emit('named-event', {
'data1': 'value1',
'data2':'value2'
});
In this example when the JS loads, it will emit to the socket a "named-event" sending the data in JSON to the node.js/socket.io server.
Using the io and socket on the server under path /nodejs (connected by client), receives the data an then resends it as a broadcast. Any other users in the socket would receive the data with their listener "named-event-broadcast". Note that the sender does not receive their own broadcast.

You can use pandas.Dataframe.isin
.
pandas.Dateframe.isin
will return boolean values depending on whether each element is inside the list a
or not. You then invert this with the ~
to convert True
to False
and vice versa.
import pandas as pd
a = ['2015-01-01' , '2015-02-01']
df = pd.DataFrame(data={'date':['2015-01-01' , '2015-02-01', '2015-03-01' , '2015-04-01', '2015-05-01' , '2015-06-01']})
print(df)
# date
#0 2015-01-01
#1 2015-02-01
#2 2015-03-01
#3 2015-04-01
#4 2015-05-01
#5 2015-06-01
df = df[~df['date'].isin(a)]
print(df)
# date
#2 2015-03-01

Yes you can do it yourself. It is just a matter of grabbing the sources of the page and parsing them the way you want.
There are various possibilities. A good combo is using python-requests (built on top of urllib2, it is urllib.request
in Python3) and BeautifulSoup4, which has its methods to select elements and also permits CSS selectors:
import requests
from BeautifulSoup4 import BeautifulSoup as bs
request = requests.get("http://foo.bar")
soup = bs(request.text)
some_elements = soup.find_all("div", class_="myCssClass")
Some will prefer xpath parsing or jquery-like pyquery, lxml or something else.
When the data you want is produced by some JavaScript, the above won't work. You either need python-ghost or Selenium. I prefer the latter combined with PhantomJS, much lighter and simpler to install, and easy to use:
from selenium import webdriver
client = webdriver.PhantomJS()
client.get("http://foo")
soup = bs(client.page_source)

If you want to selectively remove links without having to copy/edit entire xml files, a nice solution can be found in this post in the magento forums
In this solution, you override the Mage_Customer_Block_Account_Navigation
block with a local version, that adds a removeLinkByName
method, which you then use in your layout.xml
files, like so:
<?xml version="1.0"?>
<layout version="0.1.0">
<customer_account>
<reference name="customer_account_navigation" >
<!-- remove the link using your custom method -->
<action method="removeLinkByName">
<name>recurring_profiles</name>
</action>
<action method="removeLinkByName">
<name>billing_agreements</name>
</action>
</reference>
</customer_account>
</layout>
There's a couple ways of doing this. As long as the WAR file is expanded (a set of files instead of one .war file), you can use this API:
ServletContext context = getContext();
String fullPath = context.getRealPath("/WEB-INF/test/foo.txt");
That will get you the full system path to the resource you are looking for. However, that won't work if the Servlet Container never expands the WAR file (like Tomcat). What will work is using the ServletContext's getResource
methods.
ServletContext context = getContext();
URL resourceUrl = context.getResource("/WEB-INF/test/foo.txt");
or alternatively if you just want the input stream:
InputStream resourceContent = context.getResourceAsStream("/WEB-INF/test/foo.txt");
The latter approach will work no matter what Servlet Container you use and where the application is installed. The former approach will only work if the WAR file is unzipped before deployment.
EDIT:
The getContext() method is obviously something you would have to implement. JSP pages make it available as the context
field. In a servlet you get it from your ServletConfig
which is passed into the servlet's init()
method. If you store it at that time, you can get your ServletContext any time you want after that.

MongoDB has a simple web based administrative port at 28017 by default.
There is no HTTP access at the default port of 27017 (which is what the error message is trying to suggest). The default port is used for native driver access, not HTTP traffic.
To access MongoDB, you'll need to use a driver like the MongoDB native driver for NodeJS. You won't "POST" to MongoDB directly (but you might create a RESTful API using express which uses the native drivers). Instead, you'll use a wrapper library that makes accessing MongoDB convenient. You might also consider using Mongoose (which uses the native driver) which adds an ORM-like model for MongoDB in NodeJS.
If you can't get to the web interface, it may be disabled. Normally, I wouldn't expect that you'd need it for doing development unless you're checking logs and such.

It's worth mentioning that the validation properties are different for forms and form elements (note that touched and untouched are for fields only):
Input fields have the following states: $untouched The field has not been touched yet $touched The field has been touched $pristine The field has not been modified yet $dirty The field has been modified $invalid The field content is not valid $valid The field content is valid They are all properties of the input field, and are either true or false. Forms have the following states: $pristine No fields have been modified yet $dirty One or more have been modified $invalid The form content is not valid $valid The form content is valid $submitted The form is submitted They are all properties of the form, and are either true or false.
Update PHP 7.4
Curly brace access syntax is deprecated since PHP 7.4
Update 2019
Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.
Simply iterate its using {}
Example:
$videos{0}->id
This way your object is not destroyed and you can easily iterate through object.
For PHP 5.6 and below use this
$videos{0}['id']
Both array() and the stdClass objects can be accessed using the
current()
key()
next()
prev()
reset()
end()
functions.
So, if your object looks like
object(stdClass)#19 (3) {
[0]=>
object(stdClass)#20 (22) {
["id"]=>
string(1) "123"
etc...
Then you can just do;
$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object
If you need the key for some reason, you can do;
reset($obj); //Ensure that we're at the first element
$key = key($obj);
Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4
2022 Update:
After PHP 7.4, using current()
, end()
, etc functions on objects is deprecated.
In newer versions of PHP, use the ArrayIterator class:
$objIterator = new ArrayIterator($obj);
$id = $objIterator->current()->id; // Gets the 'id' attr of the first entry in the object
$key = $objIterator->key(); // and gets the key

If one line code is definitely going to happen for you, Python 3.8 introduces assignment expressions affectionately known as “the walrus operator”.

someBoolValue and (num := 20)
The 20

if the first boolean expression is True
. The assignment must be inside parentheses here otherwise you will get a syntax error.

This answer is based on Array.forEach
, without any library, just native vanilla.
To basically call something()
3 times, use:
[1,2,3].forEach(function(i) {
something();
});
considering the following function:
function something(){ console.log('something') }
The outpout will be
something
something
something
To complete this questions, here's a way to do call something()
1, 2 and 3 times respectively:
[1,2,3].forEach(i => Array(i).fill(i).forEach(_ => {
something()
}))
[1,2,3].forEach(function(i) {
Array(i).fill(i).forEach(function() {
something()
})
}))
In both cases, the outpout will be
The outpout will be
something
something
something
something
something
something
(once, then twice, then 3 times)

Regardless of what you're trying to do there should be no need to read to and write to a file at the same time. It would also use more memory which should always be avoided. I'd suggest reading the entire file using the .ReadAll method and then close it and do whatever you need to do with the data (assuming you read the contents into a variable) and then do a write to the same file and overwrite the file. If you're concerned with having something go wrong when over-writing the current file you could always try to write it to a different file and throw an error if that doesn't work before trying to over-write the original.

You need to make the strings raw and use latex:

As of matplotlib 2.0 the default font supports most western alphabets and can simple do
ax.set_xlabel('?')
with unicode.
(This answer might seem needlessly complicated, but it’s easily extensible and robust regarding whitespace and special characters, as far as I know.)
You can feed data right through the standard input of the ssh
command and read
that from the remote location.
In the following example,
ssh
a null-terminated line giving the name and value of the variable.shh
command itself, we loop through these lines to initialise the required variables.# Initialize examples of variables.
# The first one even contains whitespace and a newline.
readonly FOO=$'apjlljs ailsi \n ajlls\t éjij'
readonly BAR=ygnàgyààynygbjrbjrb
# Make a list of what you want to pass through SSH.
# (The “unset” is just in case someone exported
# an associative array with this name.)
unset -v VAR_NAMES
readonly VAR_NAMES=(
FOO
BAR
)
for name in "${VAR_NAMES[@]}"
do
printf '%s %s\0' "$name" "${!name}"
done | ssh [email protected] '
while read -rd '"''"' name value
do
export "$name"="$value"
done
# Check
printf "FOO = [%q]; BAR = [%q]\n" "$FOO" "$BAR"
'
Output:
FOO = [$'apjlljs ailsi \n ajlls\t éjij']; BAR = [ygnàgyààynygbjrbjrb]
If you don’t need to export
those, you should be able to use declare
instead of export
.
A really simplified version (if you don’t need the extensibility, have a single variable to process, etc.) would look like:
$ ssh [email protected] 'read foo' <<< "$foo"
EXEC sp_helpuser
or
SELECT * FROM sysusers
Both of these select all the users of the current database (not the server).
If I understand correctly, what you want to do, in pseudo-code is the following:
for (Tweet tweet : tweets) {
if (!db.containsTweet(tweet.getId())) {
db.insertTweet(tweet.getText(), tweet.getId());
}
}
I assume your db class actually uses an sqlite database as a backend? What you could do is implement containsTweet
directly and just query the database each time, but that seems less than perfect. The easiest solution if we go by your base code is to just keep a Set
around that indexes the tweets. Since I can't be sure what the equals()
method of Tweet
looks like, I'll just store the identifiers in there. Then you get:
Set<Integer> tweetIds = new HashSet<Integer>(); // or long, whatever
for (Tweet tweet : tweets) {
if (!tweetIds.contains(tweet.getId())) {
db.insertTweet(tweet.getText(), tweet.getId());
tweetIds.add(tweet.getId());
}
}
It would probably be better to save a tiny bit of this work, by sorting the list of tweets
to begin with and then just filtering out duplicate tweets. You could use:
// if tweets is a List
Collections.sort(tweets, new Comparator() {
public int compare (Object t1, Object t2) {
// might be the wrong way around
return ((Tweet)t1).getId() - ((Tweet)t2).getId();
}
}
Then process it
Integer oldId;
for (Tweet tweet : tweets) {
if (oldId == null || oldId != tweet.getId()) {
db.insertTweet(tweet.getText(), tweet.getId());
}
oldId = tweet.getId();
}
Yes, you could do this using a second for-loop, but you'll run into performance problems much more quickly than with this approach (although what we're doing here is trading time for memory performance, of course).
Change your config.php:
$config['sess_use_database'] = TRUE;

Use Assembly.GetTypes
. For example:
Assembly mscorlib = typeof(string).Assembly;
foreach (Type type in mscorlib.GetTypes())
{
Console.WriteLine(type.FullName);
}
I wouldn't risk it because you might end up losing data that should have been preserved. hbm2ddl.auto=update is purely an easy way to keep your dev database up to date.
You haven't properly cased your onchange
prop in the input
. It needs to be onChange
in JSX.
<input
type="text"
value={this.props.searchString}
ref="searchStringInput"
onchange={this.handleChange} <--[should be onChange]
/>
The topic of passing a value
prop to an <input>
, and then somehow changing the value passed in response to user interaction using an onChange
handler is pretty well-considered in the docs.
They refer to such inputs as Controlled Components, and refer to inputs that instead let the DOM natively handle the input's value and subsequent changes from the user as Uncontrolled Components.
Whenever you set the value
prop of an input
to some variable, you have a Controlled Component. This means you must change the value of the variable by some programmatic means or else the input will always hold that value and will never change, even when you type -- the native behaviour of the input, to update its value on typing, is overridden by React here.
So, you're correctly taking that variable from state, and have a handler to update the state all set up fine. The problem was because you have onchange
and not the correct onChange
the handler was never being called and so the value
was never being updated when you type into the input. When you do use onChange
the handler is called, the value
is updated when you type, and you see your changes.
List<String> arrayList = new ArrayList<String>();
for (String s : arrayList) {
if(s.equals(value)){
//do something
}
}
or
for (int i = 0; i < arrayList.size(); i++) {
if(arrayList.get(i).equals(value)){
//do something
}
}
But be carefull ArrayList can hold null values. So comparation should be
value.equals(arrayList.get(i))
when you are sure that value is not null or you should check if given element is null.
Yay recursion!
def trunc(s,l):
if l > 0:
return s[:l] + trunc(s, l - len(s))
return ''
Won't scale forever, but it's fine for smaller strings. And it's pretty.
I admit I just read the Little Schemer and I like recursion right now.

element to be a fullworthy URL. It still remains #
.
<h:form>
<h:commandLink value="link text" action="destination?faces-redirect=true" />
</h:form>
Since JSF 2.0, there's also the <h:link>
which can take a view ID (a navigation case outcome) instead of an URL. It will generate a HTML <a>
element as well with the proper URL in href
.
<h:link value="link text" outcome="destination" />
So, if it's for pure and bookmarkable page-to-page navigation like the SO username link, then use <h:outputLink>
or <h:link>
. That's also better for SEO since bots usually doesn't cipher POST forms nor JS code. Also, UX will be improved as the pages are now bookmarkable and the URL is not "one behind" anymore.
When necessary, you can do the preprocessing job in the constructor or @PostConstruct
of a @RequestScoped
or @ViewScoped
@ManagedBean
which is attached to the destination page in question. You can make use of @ManagedProperty
or <f:viewParam>
to set GET parameters as bean properties.
You can create a function that returns a boolean value and checks every attribute. You can call that function to do the job for you.
Alternatively, you can initialize the object with default values. That way there is no need for you to do any checking.
If you're using Python 2.5 or later, the uuid module is already included with the Python standard distribution.
Ex:
>>> import uuid
>>> uuid.uuid4()
UUID('5361a11b-615c-42bf-9bdb-e2c3790ada14')
You have to do a result.next() before you can access the result. It's a very common idiom to do
ResultSet rs = stmt.executeQuery();
while (rs.next())
{
int foo = rs.getInt(1);
...
}
From this news group posting by Mark Zbikowski himself:
The differences between .CMD and .BAT as far as CMD.EXE is concerned are: With extensions enabled, PATH/APPEND/PROMPT/SET/ASSOC in .CMD files will set ERRORLEVEL regardless of error. .BAT sets ERRORLEVEL only on errors.
In other words, if ERRORLEVEL is set to non-0 and then you run one of those commands, the resulting ERRORLEVEL will be:
onchange
is only triggered when the control is blurred. Try onkeypress
instead.
You are still in the context of your CategoryController

Below is my code for fetch. Took me while researching because jQuery.active doesn't work with fetch. Here is the answer helped me proxy fetch, but its only for ajax not fetch mock for selenium
public static void customPatchXMLHttpRequest(WebDriver driver) {

JavascriptExecutor jsDriver = (JavascriptExecutor) driver;
Object numberOfAjaxConnections = jsDriver.executeScript("return window.openHTTPs");

why do I have to pass seconds = uptime to timedelta
Because timedelta objects can be passed seconds, milliseconds, days, etc... so you need to specify what are you passing in (this is why you use the explicit key). Typecasting to int
is superfluous as they could also accept floats.
and why does the string casting works so nicely that I get HH:MM:SS ?
It's not the typecasting that formats, is the internal __str__
method of the object. In fact you will achieve the same result if you write:
print datetime.timedelta(seconds=int(uptime))
To close ajax fancybox window, use this:
onclick event -> $.fancybox.close();
return false;
If you're using Owl Carousel 2

navText : ["<i class='fa fa-chevron-left'></i>","<i class='fa fa-chevron-right'></i>"]
});

I would like to suggest a method using the LAB color channel. Wikipedia has enough information regarding what the LAB color channel is about.
I have done the following using OpenCV 3.0.0 and python:
import cv2
#-----Reading the image-----------------------------------------------------
img = cv2.imread('Dog.jpg', 1)
cv2.imshow("img",img)
#-----Converting image to LAB Color model-----------------------------------
lab= cv2.cvtColor(img, cv2.COLOR_BGR2LAB)
cv2.imshow("lab",lab)
#-----Splitting the LAB image to different channels-------------------------
l, a, b = cv2.split(lab)
cv2.imshow('l_channel', l)
cv2.imshow('a_channel', a)
cv2.imshow('b_channel', b)
#-----Applying CLAHE to L-channel-------------------------------------------
clahe = cv2.createCLAHE(clipLimit=3.0, tileGridSize=(8,8))
cl = clahe.apply(l)
cv2.imshow('CLAHE output', cl)
#-----Merge the CLAHE enhanced L-channel with the a and b channel-----------
limg = cv2.merge((cl,a,b))
cv2.imshow('limg', limg)
#-----Converting image from LAB Color model to RGB model--------------------
final = cv2.cvtColor(limg, cv2.COLOR_LAB2BGR)
cv2.imshow('final', final)
#_____END_____#
You can run the code as it is. To know what CLAHE (Contrast Limited Adaptive Histogram Equalization)is about, you can again check Wikipedia.
this will do the job easily to get the last part of the required URL
$url="http://domain.com/artist/song/music-videos/song-title/9393903";
$requred_string= substr(strrchr($url, "/"), 1);
this will get you the string after first "/" from the right.
Any other solution/library is in the end going to use reflection to introspect the type...
HttpContext.Response.AddHeader("content-disposition","attachment; filename=form.pdf");
if the filename is generating dynamically then how to define filename here, it is generating through guid here.
Here are the steps:
click File > Import. The Import window opens.
Under Select an import source, click J2EE > App Client JAR file.
Click Next.
In the Application Client file field, enter the location and name of the application client JAR file that you want to import. You can click the Browse button to select the JAR file from the file system.
In the Application Client project field, type a new project name or select an application client project from the drop-down list. If you type a new name in this field, the application client project will be created based on the version of the application client JAR file, and it will use the default location.
In the Target runtime drop-down list, select the application server that you want to target for your development. This selection affects the run time settings by modifying the class path entries for the project.
If you want to add the new module to an enterprise application project, select the Add project to an EAR check box and then select an existing enterprise application project from the list or create a new one by clicking New.
Note: If you type a new enterprise application project name, the enterprise application project will be created in the default location with the lowest compatible J2EE version based on the version of the project being created. If you want to specify a different version or a different location for the enterprise application, you must use the New Enterprise Application Project wizard.
Click Finish to import the application client JAR file.
If you want to parse using InputStreams
public Object xmlToObject(String xmlDataString) {
Object converted = null;
try {
JAXBContext jc = JAXBContext.newInstance(Response.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
InputStream stream = new ByteArrayInputStream(xmlDataString.getBytes(StandardCharsets.UTF_8));
converted = unmarshaller.unmarshal(stream);
} catch (JAXBException e) {
e.printStackTrace();
}
return converted;
}
You can use StringFormat in Silverlight 4 to provide a custom formatting of the value you bind to.
The date formatting has a huge range of options.
For the DateTime of “April 17, 2004, 1:52:45 PM”
You can either use a set of standard formats (standard formats)…
StringFormat=f : “Saturday, April 17, 2004 1:52 PM”
StringFormat=g : “4/17/2004 1:52 PM”
StringFormat=m : “April 17”
StringFormat=y : “April, 2004”
StringFormat=t : “1:52 PM”
StringFormat=u : “2004-04-17 13:52:45Z”
StringFormat=o : “2004-04-17T13:52:45.0000000”
… or you can create your own date formatting using letters (custom formats)
StringFormat=’MM/dd/yy’ : “04/17/04”
StringFormat=’MMMM dd, yyyy g’ : “April 17, 2004 A.D.”
StringFormat=’hh:mm:ss.fff tt’ : “01:52:45.000 PM”
In case you haven't come to a conclusion... I took Henrique's answer and gave a better logic solution. This is completely compatible with PHPSpreadSheet in case someone is using PHPSpreadSheet or PHPExcel.
$spreadOrPhpExcel = new SpreadSheet(); // or new PHPExcel();
print_in_sheet($spreadOrPhpExcel);
function print_in_sheet($spread)
{
$sheet = 0;
foreach( getData() as $report => $value ){
# If number of sheet is 0 then no new worksheets are created
if( $sheet > 0 ){
$spread->createSheet();
}
# Index for the worksheet is setted and a title is assigned
$wSheet = $spread->setActiveSheetIndex($sheet)->setTitle($report);
# Printing data
$wSheet->setCellValue("A1", "Hello World!");
# Index number is incremented for the next worksheet
$sheet++;
}
return $spread;
}

branch HEAD.
$ git add .
$ git stash
$ git checkout master
Jump Over Commits Back and Forth:
Go to a specific commit-sha

$ git checkout - # back to the previous state
Here's a neat solution:
String upToNCharacters = s.substring(0, Math.min(s.length(), n));
Opinion: while this solution is "neat", I think it is actually less readable than a solution that uses if
/ else
in the obvious way. If the reader hasn't seen this trick, he/she has to think harder to understand the code. IMO, the code's meaning is more obvious in the if
/ else
version. For a cleaner / more readable solution, see @paxdiablo's answer.
Just add autofocus
in first input or textarea.
<input type="text" name="name" id="xax" autofocus="autofocus" />
In case someone else stumbles onto this topic - here's a more "one size fits all" solution.
If you are using .git
or .svn
, you can use the --exclude-vcs
option for tar. This will ignore many different files/folders required by different version control systems.

Just a side note to the discussion about JVM and JIT Compilation. This is the same principle as with C# and the CLR and to some extent in Python, and when somebody says that the code runs "directly on hardware" that is actually true in that instructions that is already compiled will be able to take advantage of optimization on the machine/cpu it's being run on. So even if the initial compilation of a module is rather slow, the next time this module is run, the code being executed runs at native speed and thus runs directly on hardware so to say.
Other alternative:
JAXBElement<String> element = new JAXBElement<>(new QName("Your localPart"),
String.class, "Your message");
Then:
System.out.println(element.getValue()); // Result: Your message
In some cases, i.e. when (if) you're just using float
to have elements flow on the same "line", you might use
display: inline-block;
instead of
float: left;
Otherwise, using a clear
element at the end works, even if it may go against the grain to need an element to do what should be CSS work.
You should read this getopts tutorial.

done
Like greybot said(getopt
!= getopts
) :
The external command getopt(1) is never safe to use, unless you know it is GNU getopt, you call it in a GNU-specific way, and you ensure that GETOPT_COMPATIBLE is not in the environment. Use getopts (shell builtin) instead, or simply loop over the positional parameters.
If you want the threads to stop when your program exits (as implied by your example), then make them daemon threads.
If you want your threads to die on command, then you have to do it by hand. There are various methods, but all involve doing a check in your thread's loop to see if it's time to exit (see Nix's example).
EDIT:
I don't think Any of the commands will work. In linux Ctrl-L will do the job. in windows there is no equivalent. You can only Exit MySql, Type CLS
and then re-enter MySql.
I'd like to add to @MBK's answer. Although I found @MBK's answer to be very helpful in solving a similar problem, it'd be better if @MBK included a screenshot of how to filter a particular column.
Use is simple:
convert(date, Btch_Time)
Example below:
Table:
Efft_d Loan_I Loan_Purp_Type_C Orig_LTV Curr_LTV Schd_LTV Un_drwn_Bal_a Btch_Time Strm_I Btch_Ins_I
2014-05-31 200312500 HL03 NULL 1.0000 1.0000 1.0000 2014-06-17 11:10:57.330 1005 24851e0a-53983699-14b4-69109
Select * from helios.dbo.CBA_SRD_Loan where Loan_I in ('200312500') and convert(date, Btch_Time) = '2014-06-17'
There are two types of exception, You can recover from checked exception if you get such kind of exception. Runtime exception are irrecoverable, runtime exceptions are programming errors, and programmer should take care of it while writing the code, and continue execution of this might give you incorrect result. Runtime exceptions are about violating precondition ex. you have an array of size 10, and you are trying to access 11 th element, it will throw ArrayIndexOutOfBoundException
All answers were just a suggested solutions or workarounds. But still don't get answer to the question: why margin:auto works with position:relative but does not with position:absolute.
Following explanation was helpful for me:
"Margins make little sense on absolutely positioned elements since such elements are removed from the normal flow, thus they cannot push away any other elements on the page. Using margins like this can only affect the placement of the element to which the margin is applied, not any other element." http://www.justskins.com/forums/css-margins-and-absolute-82168.html

use Python OS module to find csv file in a directory.
the simple example is here :
import os
# This is the path where you want to search
path = r'd:'
# this is the extension you want to detect
extension = '.csv'
for root, dirs_list, files_list in os.walk(path):
for file_name in files_list:
if os.path.splitext(file_name)[-1] == extension:
file_name_path = os.path.join(root, file_name)
print file_name
print file_name_path # This is the full path of the filter file
Assuming there is a column named business:
SELECT Business, COUNT(*) FROM eventsTable GROUP BY Business
If you need just file names like:
dir/subdir/file1.txt
dir/subdir2/file2.sql
dir2/subdir3/file6.php
(which I use as a source for tar command) you will also need to filter out commit messages.
In order to do this I use following command:
git log --name-only --oneline | grep -v '.{7} '
Grep command excludes (-v
param) every line which starts with seven symbols (which is the length of my git hash for git log
command) followed by space. So it filters out every git hash message
line and leave only lines with file names.
One useful improvement is to append uniq
to remove duplicate lines so it will looks as follow:
git log --name-only --oneline | grep -v '.{7} ' | uniq
I was getting this error by saving an object to the shared preferences as a gson converted string. The gson String was no good, so retrieving and deserializing the object was not actually working correctly. This meant any subsequent accesses to the object resulted in this error. Scary :)
This should work:
$("#table-filters>ul>li.active").removeClass("active");
//Find all `li`s with class `active`, children of `ul`s, children of `table-filters`
See jQuery.scroll(). You can bind this to the window element to get your desired event hook.
On scroll, then simply check your scroll position:
$(window).scroll(function() {
var scrollTop = $(window).scrollTop();
if ( scrollTop > $(headerElem).offset().top ) {
// display add
}
});
Unicode is a fairly complex standard. Don’t be too afraid, but be prepared for some work! [2]
Because a credible resource is always needed, but the official report is massive, I suggest reading the following:
A brief explanation:
Computers read bytes and people read characters, so we use encoding standards to map characters to bytes. ASCII was the first widely used standard, but covers only Latin (7 bits/character can represent 128 different characters). Unicode is a standard with the goal to cover all possible characters in the world (can hold up to 1,114,112 characters, meaning 21 bits/character max. Current Unicode 8.0 specifies 120,737 characters in total, and that's all).
The main difference is that an ASCII character can fit to a byte (8 bits), but most Unicode characters cannot. So encoding forms/schemes (like UTF-8 and UTF-16) are used, and the character model goes like this:
Every character holds an enumerated position from 0 to 1,114,111 (hex: 0-10FFFF) called code point.
An encoding form maps a code point to a code unit sequence. A code unit is the way you want characters to be organized in memory, 8-bit units, 16-bit units and so on. UTF-8 uses 1 to 4 units of 8 bits, and UTF-16 uses 1 or 2 units of 16 bits, to cover the entire Unicode of 21 bits max. Units use prefixes so that character boundaries can be spotted, and more units mean more prefixes that occupy bits. So, although UTF-8 uses 1 byte for the Latin script it needs 3 bytes for later scripts inside Basic Multilingual Plane, while UTF-16 uses 2 bytes for all these. And that's their main difference.
Lastly, an encoding scheme (like UTF-16BE or UTF-16LE) maps (serializes) a code unit sequence to a byte sequence.
character: p
code point: U+03C0
encoding forms (code units):
UTF-8: CF 80
UTF-16: 03C0
encoding schemes (bytes):
UTF-8: CF 80
UTF-16BE: 03 C0
UTF-16LE: C0 03
Tip: a hex digit represents 4 bits, so a two-digit hex number represents a byte
Also take a look at Plane maps in Wikipedia to get a feeling of the character set layout
You can reference gems with source:
source: 'https://source.com', git repository (:github => 'git/url')
and with local path
:path => '.../path/gem_name'
.
You can learn more about [Gemfiles and how to use them] (https://kolosek.com/rails-bundle-install-and-gemfile) in this article.
If you have a full DB dump:
PGPASSWORD="your_pass" psql -h "your_host" -U "your_user" -d "your_database" -f backup.sql
If you have schemas kept separately, however, that won't work. Then you'll need to disable triggers for data insertion, akin to pg_restore --disable-triggers
. You can then use this:
cat database_data_only.gzip | gunzip | PGPASSWORD="your_pass" psql -h "your_host" -U root "your_database" -c 'SET session_replication_role = replica;' -f /dev/stdin
On a side note, it is a very unfortunate downside of postgres, I think. The default way of creating a dump in pg_dump
is incompatible with pg_restore
. With some additional keys, however, it is. WTF?
Unless you're writing code that will be called millions of times per second (such as, e.g., drawing a line to the screen in a graphics application), integer vs. floating-point arithmetic is rarely the bottleneck.
The usual first step to the efficiency questions is to profile your code to see where the run-time is really spent. The linux command for this is gprof
.
Edit:
Though I suppose you can always implement the line drawing algorithm using integers and floating-point numbers, call it a large number of times and see if it makes a difference:
I use the following one liner in Terminal.
$ rake db:drop && rake db:create && rake db:migrate && rake db:schema:dump && rake db:test:prepare
I put this as a shell alias and named it remigrate
By now, you can easily "chain" Rails tasks:
$ rake db:drop db:create db:migrate db:schema:dump db:test:prepare # db:test:prepare no longer available since Rails 4.1.0.rc1+
In case you're here looking for something to list the keys of an n-depth nested object as a flat array:
const getObjectKeys = (obj, prefix = '') => {_x000D_
return Object.entries(obj).reduce((collector, [key, val]) => {_x000D_
const newKeys = [ ...collector, prefix ? `${prefix}.${key}` : key ]_x000D_
if (Object.prototype.toString.call(val) === '[object Object]') {_x000D_
const newPrefix = prefix ? `${prefix}.${key}` : key_x000D_
const otherKeys = getObjectKeys(val, newPrefix)_x000D_
return [ ...newKeys, ...otherKeys ]_x000D_
}_x000D_
return newKeys_x000D_
}, [])_x000D_
}_x000D_
_x000D_
console.log(getObjectKeys({a: 1, b: 2, c: { d: 3, e: { f: 4 }}}))
_x000D_

The most accepted answer as of this writing (January 2014) is:
drop schema public cascade;
create schema public;
This does work, however if your intention is to restore the public schema to its virgin state this does not fully accomplish the task. Under pgAdmin III for PostgreSQL 9.3.1, if you click on the "public" schema created this way and look in the "SQL pane" you will see the following:
-- Schema: public
-- DROP SCHEMA public;
CREATE SCHEMA public
AUTHORIZATION postgres;
However, by contrast a brand new database will have the following:
-- Schema: public
-- DROP SCHEMA public;
CREATE SCHEMA public
AUTHORIZATION postgres;
GRANT ALL ON SCHEMA public TO postgres;
GRANT ALL ON SCHEMA public TO public;
COMMENT ON SCHEMA public
IS 'standard public schema';
For me using a python web framework which creates database tables (web2py), using the former caused problems:
<class 'psycopg2.ProgrammingError'> no schema has been selected to create in
So to my mind the fully correct answer is:
DROP SCHEMA public CASCADE;
CREATE SCHEMA public;
GRANT ALL ON SCHEMA public TO postgres;
GRANT ALL ON SCHEMA public TO public;
COMMENT ON SCHEMA public IS 'standard public schema';
Also note to issue these commands in pgAdmin III, I used the Query tool ( magnifying glass icon "Execute abritrary SQL queries") or you could use Plugins-> PSQL Console
Note
If you have any extensions installed they will be dropped when you drop the schema, so you should make note of what you need installed and then execute statements as necessary. E.g.
CREATE EXTENSION postgis;
start cmd.exe
opens a separate window
start file.cmd
opens the batch file and executes it in another command prompt
Updating to use tibble()
You can pass a named vector of length greater than 1 to the by
argument of left_join()
:
library(dplyr)
d1 <- tibble(
x = letters[1:3],
y = LETTERS[1:3],
a = rnorm(3)
)
d2 <- tibble(
x2 = letters[3:1],
y2 = LETTERS[3:1],
b = rnorm(3)
)
left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))
You used wrong letter case for year in line:
@JsonFormat(pattern = "YYYY-MM-dd HH:mm")
Should be:
@JsonFormat(pattern = "yyyy-MM-dd HH:mm")
With this change everything is working as expected.
From the docs:-
Your app gradle file now has to explicitly list
com.google.firebase:firebase-core
as a dependency for Firebase services to work as expected.
Add:
implementation 'com.google.firebase:firebase-core:16.0.1'
and in top level gradle file use the latest version of google play services:
classpath 'com.google.gms:google-services:4.0.2'
https://firebase.google.com/support/release-notes/android
https://bintray.com/android/android-tools/com.google.gms.google-services
Note:
You need to add the google()
repo in the top level gradle file, as specified in the firebase docs and also it should be before jcenter()
:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:4.0.2'
}
}
allprojects {
repositories {
google()
jcenter()
}

If we use Kotlin it is shorter. Example of class which responds for provide call logs:
import android.content.Context
import android.database.Cursor
import android.provider.CallLog.Calls.*
class CallsLoader {
fun getCallLogs(context: Context): List<List<String?>> {
val c = context.applicationContext
val projection = arrayOf(CACHED_NAME, NUMBER, TYPE, DATE, DURATION)
val cursor = c.contentResolver.query(
CONTENT_URI,
projection,
null,
null,
null,
null
)
return cursorToMatrix(cursor)
}
private fun cursorToMatrix(cursor: Cursor?): List<List<String?>> {
val matrix = mutableListOf<List<String?>>()
cursor?.use {
while (it.moveToNext()) {
val list = listOf(
it.getStringFromColumn(CACHED_NAME),
it.getStringFromColumn(NUMBER),
it.getStringFromColumn(TYPE),
it.getStringFromColumn(DATE),
it.getStringFromColumn(DURATION)
)
matrix.add(list.toList())
}
}
return matrix
}
private fun Cursor.getStringFromColumn(columnName: String) =
getString(getColumnIndex(columnName))
}
We can also convert cursor to map:
fun getCallLogs(context: Context): Map<String, Array<String?>> {
val c = context.applicationContext
val projection = arrayOf(CACHED_NAME, NUMBER, TYPE, DATE, DURATION)
val cursor = c.contentResolver.query(
CONTENT_URI,
projection,
null,
null,
null,
null
)
return cursorToMap(cursor)
}
private fun cursorToMap(cursor: Cursor?): Map<String, Array<String?>> {
val arraySize = cursor?.count ?: 0
val map = mapOf(
CACHED_NAME to Array<String?>(arraySize) { "" },
NUMBER to Array<String?>(arraySize) { "" },
TYPE to Array<String?>(arraySize) { "" },
DATE to Array<String?>(arraySize) { "" },
DURATION to Array<String?>(arraySize) { "" }
)
cursor?.use {
for (i in 0 until arraySize) {
it.moveToNext()
map[CACHED_NAME]?.set(i, it.getStringFromColumn(CACHED_NAME))
map[NUMBER]?.set(i, it.getStringFromColumn(NUMBER))
map[TYPE]?.set(i, it.getStringFromColumn(TYPE))
map[DATE]?.set(i, it.getStringFromColumn(DATE))
map[DURATION]?.set(i, it.getStringFromColumn(DURATION))
}
}
return map
}
This same issue happened to me when I had more than one API function in the module and tried to wrap each function with 2 decorators:
I got this same exception because I tried to wrap more than one function with those two decorators:
@app.route("/path1")
@exception_handler
def func1():
pass
@app.route("/path2")
@exception_handler
def func2():
pass
Specifically, it is caused by trying to register a few functions with the name wrapper:
def exception_handler(func):
def wrapper(*args, **kwargs):
try:
return func(*args, **kwargs)
except Exception as e:
error_code = getattr(e, "code", 500)
logger.exception("Service exception: %s", e)
r = dict_to_json({"message": e.message, "matches": e.message, "error_code": error_code})
return Response(r, status=error_code, mimetype='application/json')
return wrapper
Changing the name of the function solved it for me (wrapper.__name__ = func.__name__):
def exception_handler(func):
def wrapper(*args, **kwargs):
try:
return func(*args, **kwargs)
except Exception as e:
error_code = getattr(e, "code", 500)
logger.exception("Service exception: %s", e)
r = dict_to_json({"message": e.message, "matches": e.message, "error_code": error_code})
return Response(r, status=error_code, mimetype='application/json')
# Renaming the function name:
wrapper.__name__ = func.__name__
return wrapper
Then, decorating more than one endpoint worked.
How to Bold entire row 10 example:
workSheet.Cells[10, 1].EntireRow.Font.Bold = true;
More formally:
Microsoft.Office.Interop.Excel.Range rng = workSheet.Cells[10, 1] as Xl.Range;
rng.EntireRow.Font.Bold = true;
How to Bold Specific Cell 'A10' for example:
workSheet.Cells[10, 1].Font.Bold = true;
Little more formal:
int row = 1;
int column = 1; /// 1 = 'A' in Excel
Microsoft.Office.Interop.Excel.Range rng = workSheet.Cells[row, column] as Xl.Range;
rng.Font.Bold = true;
You mentioned getting the result list from the Query, since you don't know that there is a UniqueResult (hence the exception) you could use list and check the size?
if (query.list().size() == 1)
Since you're not doing a get() to get your unique object a query will be executed whether you call uniqueResult or list.
I encounter a problem in quasar
which is a mobile framework based vue
, the tidle syntax ~assets/cover.jpg
works in normal component, but not in my dynamic defined component, that is defined by
let c=Vue.component('compName',{...})
finally this work:
computed: {
coverUri() {
return require('../assets/cover.jpg');
}
}
<q-img class="coverImg" :src="coverUri" :height="uiBook.coverHeight" spinner-color="white"/>
according to the explain at https://quasar.dev/quasar-cli/handling-assets
In *.vue components, all your templates and CSS are parsed by vue-html-loader and css-loader to look for asset URLs. For example, in <img src="./logo.png"> and background: url(./logo.png), "./logo.png" is a relative asset path and will be resolved by Webpack as a module dependency.
python -m timeit -h
Set style= "display:none;"
. By setting visible=false
, it will not render button in the browser. Thus,client side script wont execute.
<asp:Button ID="savebtn" runat="server" OnClick="savebtn_Click" style="display:none" />
html markup should be
<button id="btnsave" onclick="fncsave()">Save</button>
Change javascript to
<script type="text/javascript">
function fncsave()
{
document.getElementById('<%= savebtn.ClientID %>').click();

You might be trying to access a control inside a control, maybe a GridView or DetailsView.
Try using something like this:
empsalary = Convert.ToInt32(((TextBox)DetailsView1.Rows[1].Cells[1].Controls[0]).Text);
You probablly have 2 different versions of hibernate-jpa-api on the classpath. To check that run:
mvn dependency:tree >dep.txt
Then search if there are hibernate-jpa-2.0-api and hibernate-jpa-2.1-api. And exclude the excess one.
You need to have installed Microsoft Visual Studio Tools for Office (VSTO).
VSTO can be selected in the Visual Studio installer under Workloads > Web & Cloud > Office/SharePoint Development.
After that create common .NET project and add the reference to Microsoft.Office.Interop.Excel
via 'Add Reference... > Assemblies' dialog.
Application excel = new Application();
Workbook wb = excel.Workbooks.Open(path);
Missing.Value
is a special reflection struct for unnecessary parameters replacement
In newer versions, the assembly reference required is called Microsoft Excel 16.0 Object Library
. If you do not have the latest version installed you might have Microsoft Excel 15.0 Object Library
, or an older version, but it is the same process to include.
By C89, variable can only be defined at the top of a block.

I think concat
is a nice way to do this. If they are present it uses the name attributes of the Series as the columns (otherwise it simply numbers them):
In [1]: s1 = pd.Series([1, 2], index=['A', 'B'], name='s1')
In [2]: s2 = pd.Series([3, 4], index=['A', 'B'], name='s2')
In [3]: pd.concat([s1, s2], axis=1)
Out[3]:
s1 s2
A 1 3
B 2 4
In [4]: pd.concat([s1, s2], axis=1).reset_index()
Out[4]:
index s1 s2
0 A 1 3
1 B 2 4
Note: This extends to more than 2 Series.
Shell scripts, no matter how they are executed, execute one command after the other. So your code will execute results.sh
after the last command of st_new.sh
has finished.
Now there is a special command which messes this up: &
cmd &
means: "Start a new background process and execute cmd
in it. After starting the background process, immediately continue with the next command in the script."
That means &
doesn't wait for cmd
to do it's work. My guess is that st_new.sh
contains such a command. If that is the case, then you need to modify the script:
cmd &
BACK_PID=$!
This puts the process ID (PID) of the new background process in the variable BACK_PID
. You can then wait for it to end:
while kill -0 $BACK_PID ; do
echo "Process is still active..."
sleep 1
# You can add a timeout here if you want
done
or, if you don't want any special handling/output simply
wait $BACK_PID
Note that some programs automatically start a background process when you run them, even if you omit the &
. Check the documentation, they often have an option to write their PID to a file or you can run them in the foreground with an option and then use the shell's &
command instead to get the PID.
call EnumProcesses()
and check if the PID is in the list.

Another option is
devtools::unload("your-package")
This apparently also deals with the issue of registered S3 methods that are not removed with unloadNamespace()
Give your button a custom background: @drawable/material_btn_blue
When I received this error I believe it was a bug, however you should keep in mind that if you do a separate query with a SELECT statement and the same WHERE clause, then you can grab the primary ID's from that SELECT: SELECT CONCAT(primary_id, ',')
) statement and insert them into the failed UPDATE query with conditions -> "WHERE [primary_id] IN ([list of comma-separated primary ID's from the SELECT statement)" which allows you to alleviate any issues being caused by the original (failed) query's WHERE clause.
For me, personally, when I was using quotes for the values in the "WHERE ____ IN ([values here])", only 10 of the 300 expected entries were being affected which, in my opinion, seems like a bug.
For i = 0 To dt.Rows.Count - 1

.getBoundingClientRect() returns the size of an element and its position relative to the viewport.We can easily get following
Example :

element.getBoundingClientRect().width;
Simply saying, Java context means Java native
methods all together.
In next Java code two lines of code needs context: // (1)
and // (2)
import java.io.*;
public class Runner{
public static void main(String[] args) throws IOException { // (1)
File file = new File("D:/text.txt");
String text = "";
BufferedReader reader = new BufferedReader(new FileReader(file));
String line;
while ((line = reader.readLine()) != null){ // (2)
text += line;
}
System.out.println(text);
}
}
(1) needs context because is invoked by Java native method private native void java.lang.Thread.start0();
(2) reader.readLine()
needs context because invokes Java native method public static native void java.lang.System.arraycopy(Object src, int srcPos, Object dest, int destPos, int length);
PS.
That is what BalusC is sayed about pattern Facade more strictly.
tl;dr What to do in modern (2018) times? Assume tel:
is supported, use it and forget about anything else.
The tel:
URI scheme RFC5431 (as well as sms:
but also feed:
, maps:
, youtube:
and others) is handled by protocol handlers (as mailto:
and http:
are).
They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto:
protocol handler with same meaning and behaviour of tel:
but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.
What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler()
and related functions) simplifying also the check for their support through isProtocolHandlerRegistered()
function.
There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).
In general what I suggest is:
tel:
is supported (yes, it's not true for very old devices but IMO you can ignore them).tel:
isn't supported then change links to use callto:
and repeat check desctibed in 3.tel:
and callto:
aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href
with javascript:void(0)
and (if number isn't repeated in text span) putting, telephone number in title
. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto:
and tel:
.Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:
tel:
is supported.tel:
with callto:
.tel:
or leave it as is (assuming there are good chances Skype is installed).Uri is serializable, so you can save strings and convert it back when loading
when saving
String str = myUri.toString();
and when loading
Uri myUri = Uri.parse(str);
If you want to sort based on first column (which contains number value), then try this:
arr.sort(function(a,b){
return a[0]-b[0]
})
If you want to sort based on second column (which contains string value), then try this:
arr.sort(function(a,b){
return a[1].charCodeAt(0)-b[1].charCodeAt(0)
})
P.S. for the second case, you need to compare between their ASCII values.
Hope this helps.
I know this question is a few years old and there have been a few answers to this but I thought I would add my solution just in case it helps anyone. It's in the same vein as the answer given by user2795540 and involves an array iterator.
If you're just wanting to get the first child that has the four
class then you could use the find
array iterator. Your browser will need to be able to support ES6 or you can use Babel to compile your JS into something all browsers will support. IE will not support this without a polyfill.
Using the same details you provided in your question it could look something like this:
const parentNode = document.getElementById('test');
const childNode = Array.from(parentNode.childNodes).find(({ className }) => className === 'four');
The above solution will return the node you want to target and store it in the childNode
variable.
You can find out more about the find
array iterator at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find
Expand your one liner into multiple lines. Then it becomes easy:
f.write(re.split("Tech ID:|Name:|Account #:",line)[-1])
parts = re.split("Tech ID:|Name:|Account #:",line)
wanted_part = parts[-1]
wanted_part_stripped = wanted_part.strip()
f.write(wanted_part_stripped)
SELECT DATENAME(MONTH, GETDATE())
+ RIGHT(CONVERT(VARCHAR(12), GETDATE(), 107), 9) AS [Month DD, YYYY]
OR Date without Comma Between date and year, you can use the following
SELECT DATENAME(MONTH, GETDATE()) + ' ' + CAST(DAY(GETDATE()) AS VARCHAR(2))
+ ' ' + CAST(YEAR(GETDATE()) AS VARCHAR(4)) AS [Month DD YYYY]
Basically, Serializable
is a marker interface that implies that a class is safe for serialization and the JVM determines how it is serialized. Externalizable
contains 2 methods, readExternal
and writeExternal
. Externalizable
allows the implementer to decide how an object is serialized, where as Serializable
serializes objects the default way.
If you still want to show the item but make it not clickable and look disabled with CSS:
CSS:
.disabled {
pointer-events:none; //This makes it not clickable
opacity:0.6; //This grays it out to look disabled
}
HTML:
<li class="disabled">Disabled List Item</li>
Also, if you are using BootStrap, they already have a class called disabled for this purpose. See this example.
As @LV98 pointed out, users could change this on the client side and submit a selection you weren't expecting. You will want to validate at the server as well.
Yes, there is a difference. Html.ActionLink
generates an <a href=".."></a>
tag whereas Url.Action
returns only an url.
For example:
@Html.ActionLink("link text", "someaction", "somecontroller", new { id = "123" }, null)
generates:
<a href="/somecontroller/someaction/123">link text</a>
and Url.Action("someaction", "somecontroller", new { id = "123" })
generates:
/somecontroller/someaction/123
There is also Html.Action which executes a child controller action.
Sydius outlined the types fairly well:
How about when you should use them? You will either make heavy use of scoped pointers or shared pointers. How many threads are running in your application? If the answer is "potentially a lot", shared pointers can turn out to be a performance bottleneck if used everywhere. The reason being that creating/copying/destructing a shared pointer needs to be an atomic operation, and this can hinder performance if you have many threads running. However, it won't always be the case - only testing will tell you for sure.
There is an argument (that I like) against shared pointers - by using them, you are allowing programmers to ignore who owns a pointer. This can lead to tricky situations with circular references (Java will detect these, but shared pointers cannot) or general programmer laziness in a large code base.
There are two reasons to use scoped pointers. The first is for simple exception safety and cleanup operations - if you want to guarantee that an object is cleaned up no matter what in the face of exceptions, and you don't want to stack allocate that object, put it in a scoped pointer. If the operation is a success, you can feel free to transfer it over to a shared pointer, but in the meantime save the overhead with a scoped pointer.
The other case is when you want clear object ownership. Some teams prefer this, some do not. For instance, a data structure may return pointers to internal objects. Under a scoped pointer, it would return a raw pointer or reference that should be treated as a weak reference - it is an error to access that pointer after the data structure that owns it is destructed, and it is an error to delete it. Under a shared pointer, the owning object can't destruct the internal data it returned if someone still holds a handle on it - this could leave resources open for much longer than necessary, or much worse depending on the code.
The error string is quite simply exactly what libcurl sees: since it is receiving a chunked encoding stream it knows when there is data left in a chunk to receive. When the connection is closed, libcurl knows that the last received chunk was incomplete. Then you get this error code.
There's nothing you can do to avoid this error with the request unmodified, but you can try to work around it by issuing a HTTP 1.0 request instead (since chunked encoding won't happen then) but the fact is that this is most likely a flaw in the server or in your network/setup somehow.
It's a linker error. ld
is the linker, so if you get an error message ending with "ld returned 1 exit status", that tells you that it's a linker error.
The error message tells you that none of the object files you're linking against contains a definition for avergecolumns
. The reason for that is that the function you've defined is called averagecolumns
(in other words: you misspelled the function name when calling the function (and presumably in the header file as well - otherwise you'd have gotten a different error at compile time)).

The most underrated method is insertAdjacentElement

You can literally add your HTML using one single line.
document.body.insertAdjacentElement('beforeend', html)

Similar to @Dominykas's answer, this is a decorator that converts multiargument-accepting functions into tuple-accepting functions:
apply_tuple = lambda f: lambda args: f(*args)
Example 1:
def add(a, b):
return a + b
three = apply_tuple(add)((1, 2))
Example 2:
@apply_tuple
def add(a, b):
return a + b
three = add((1, 2))
DON'T FORGET - Use parseFloat();
if your dealing with decimals.
Kaleb Pederson's solution worked for me. I updated the ColumnAttributeTypeMapper to allow a custom attribute (had requirement for two different mappings on same domain object) and updated properties to allow private setters in cases where a field needed to be derived and the types differed.
public class ColumnAttributeTypeMapper<T,A> : FallbackTypeMapper where A : ColumnAttribute
{
public ColumnAttributeTypeMapper()
: base(new SqlMapper.ITypeMap[]
{
new CustomPropertyTypeMap(
typeof(T),
(type, columnName) =>
type.GetProperties( BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance).FirstOrDefault(prop =>
prop.GetCustomAttributes(true)
.OfType<A>()
.Any(attr => attr.Name == columnName)
)
),
new DefaultTypeMap(typeof(T))
})
{
//
}
}
Just the $ (dollar sign) key. You can use A to move to the end of the line and switch to editing mode (Append). To jump the last non-blank character, you can press g then _ keys.
The opposite of A is I (Insert mode at beginning of line), as an aside. Pressing just the ^ will place your cursor at the first non-white-space character of the line.
A variation on codefin's answer
public static String concatStringsWSep(Iterable<String> strings, String separator) {
StringBuilder sb = new StringBuilder();
String sep = "";
for(String s: strings) {
sb.append(sep).append(s);
sep = separator;
}
return sb.toString();
}
Edit This will create a link with Edit after clicking on editing a function name as edit will be called.

$request = $client->post($base_url, array('content-type' => 'application/json'), json_encode($appUrl['query']));
There is a another best/effective way to solve this error,
for example, let's take a loop which counts till 10 thousand, here you may get the error Out of memory
, do to solve it you can give the computer time to recover.
So, you can sleep for 400-500ms
before you're loop counts the next number :
new Thread(new Runnable() {
public void run() {
try {
sleep(550); // 550 ms (milli seconds)
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
By doing this, will make you're program slower but you don't get any error till the heap space
is full again, so by waiting some ms
, you can prevent that error.
You can apply this method other than loop.
Hope it helped you, :D
An even simpler solution to the above:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<color android:color="@color/semitransparent_white" />
</item>
<item>
<color android:color="@color/transparent" />
</item>
</selector>
Save that in the drawable folder and you're good to go.
Sometime even after setting all it may not work. I have tried all the methods like
Nothing worked. Then I did the following which worked instantly.
Goto eclipse Run --> run configurations. Under Android Applications you can see you application. Now, on the right hand side click on the Target tab. Under the 'Additional Emulator Command line options' add the following.
-dns-server <DNS servers from your local machine upto three> -http-proxy http://<your proxy>:<your proxy port>
The catch here is that the DNS Server setting should be from your local system. Goto cmd prompt and run ipconfig to check your DNS servers. Same with the proxy server and port. Whatever works for your browser should be put in here.
You can convert it to a string, and then to an int:
print(int("".join(str(x) for x in [7,7,7,7])))
According to this : we can write this help function :
public static int convertBinaryToDecimal(String str) {
int result = 0;
for (int i = 0; i < str.length(); i++) {
int value = Character.getNumericValue(str.charAt(i));
result = result * 2 + value;
}
return result;
}
There a 3 ways to implement validation:
Validation rule example:
public class NumericValidationRule : ValidationRule
{
public Type ValidationType { get; set; }
public override ValidationResult Validate(object value, CultureInfo cultureInfo)
{
string strValue = Convert.ToString(value);
if (string.IsNullOrEmpty(strValue))
return new ValidationResult(false, $"Value cannot be coverted to string.");
bool canConvert = false;
switch (ValidationType.Name)
{
case "Boolean":
bool boolVal = false;
canConvert = bool.TryParse(strValue, out boolVal);
return canConvert ? new ValidationResult(true, null) : new ValidationResult(false, $"Input should be type of boolean");
case "Int32":
int intVal = 0;
canConvert = int.TryParse(strValue, out intVal);
return canConvert ? new ValidationResult(true, null) : new ValidationResult(false, $"Input should be type of Int32");
case "Double":
double doubleVal = 0;
canConvert = double.TryParse(strValue, out doubleVal);
return canConvert ? new ValidationResult(true, null) : new ValidationResult(false, $"Input should be type of Double");
case "Int64":
long longVal = 0;
canConvert = long.TryParse(strValue, out longVal);
return canConvert ? new ValidationResult(true, null) : new ValidationResult(false, $"Input should be type of Int64");
default:
throw new InvalidCastException($"{ValidationType.Name} is not supported");
}
}
}
XAML:
Very important: don't forget to set ValidatesOnTargetUpdated="True"
it won't work without this definition.

There are 3 problems.
1) Incorrect decimal separator
Different cultures use different decimal separators (namely ,
and .
).
If you replace .
with ,
it should work as expected:
Console.WriteLine(Convert.ToDouble("52,8725945"));
You can parse your doubles using overloaded method which takes culture as a second parameter. In this case you can use InvariantCulture
(What is the invariant culture) e.g. using double.Parse
:
double.Parse("52.8725945", System.Globalization.CultureInfo.InvariantCulture);
You should also take a look at double.TryParse
, you can use it with many options and it is especially useful to check wheter or not your string is a valid double
.
2) You have an incorrect double
One of your values is incorrect, because it contains two dots:
15.5859949000000662452.23862099999999
3) Your array has an empty value at the end, which is an incorrect double
You can use overloaded Split
which removes empty values:
string[] someArray = a.Split(new char[] { '#' }, StringSplitOptions.RemoveEmptyEntries);
The problem is that the columns used in the ORDER BY
aren't specified in the DISTINCT
. To do this, you need to use an aggregate function to sort on, and use a GROUP BY
to make the DISTINCT
work.
Try something like this:
SELECT DISTINCT Category, MAX(CreationDate)
FROM MonitoringJob
GROUP BY Category
ORDER BY MAX(CreationDate) DESC, Category
I'm sure you are using a old version. You must use the last version available at master branch:
The methods in the other answers will not work properly when the yticks are large. The ylabel will either overlap with ticks, be clipped on the left or completely invisible/outside of the figure.
I've modified Hagne's answer so it works with more than 1 column of subplots, for both xlabel and ylabel, and it shifts the plot to keep the ylabel visible in the figure.
def set_shared_ylabel(a, xlabel, ylabel, labelpad = 0.01, figleftpad=0.05):
"""Set a y label shared by multiple axes
Parameters
----------
a: list of axes
ylabel: string
labelpad: float
Sets the padding between ticklabels and axis label"""
f = a[0,0].get_figure()
f.canvas.draw() #sets f.canvas.renderer needed below
# get the center position for all plots
top = a[0,0].get_position().y1
bottom = a[-1,-1].get_position().y0
# get the coordinates of the left side of the tick labels
x0 = 1
x1 = 1
for at_row in a:
at = at_row[0]
at.set_ylabel('') # just to make sure we don't and up with multiple labels
bboxes, _ = at.yaxis.get_ticklabel_extents(f.canvas.renderer)
bboxes = bboxes.inverse_transformed(f.transFigure)
xt = bboxes.x0
if xt < x0:
x0 = xt
x1 = bboxes.x1
tick_label_left = x0
# shrink plot on left to prevent ylabel clipping
# (x1 - tick_label_left) is the x coordinate of right end of tick label,
# basically how much padding is needed to fit tick labels in the figure
# figleftpad is additional padding to fit the ylabel
plt.subplots_adjust(left=(x1 - tick_label_left) + figleftpad)
# set position of label,
# note that (figleftpad-labelpad) refers to the middle of the ylabel
a[-1,-1].set_ylabel(ylabel)
a[-1,-1].yaxis.set_label_coords(figleftpad-labelpad,(bottom + top)/2, transform=f.transFigure)
# set xlabel
y0 = 1
for at in axes[-1]:
at.set_xlabel('') # just to make sure we don't and up with multiple labels
bboxes, _ = at.xaxis.get_ticklabel_extents(fig.canvas.renderer)
bboxes = bboxes.inverse_transformed(fig.transFigure)
yt = bboxes.y0
if yt < y0:
y0 = yt
tick_label_bottom = y0
axes[-1, -1].set_xlabel(xlabel)
axes[-1, -1].xaxis.set_label_coords((left + right) / 2, tick_label_bottom - labelpad, transform=fig.transFigure)
It works for the following example, while Hagne's answer won't draw ylabel (since it's outside of the canvas) and KYC's ylabel overlaps with the tick labels:
import matplotlib.pyplot as plt
import itertools
fig, axes = plt.subplots(3, 4, sharey='row', sharex=True, squeeze=False)
fig.subplots_adjust(hspace=.5)
for i, a in enumerate(itertools.chain(*axes)):
a.plot([0,4**i], [0,4**i])
a.set_title(i)
set_shared_ylabel(axes, 'common X', 'common Y')
plt.show()
Alternatively, if you are fine with colorless axis, I've modified Julian Chen's solution so ylabel won't overlap with tick labels.
Basically, we just have to set ylims of the colorless so it matches the largest ylims of the subplots so the colorless tick labels sets the correct location for the ylabel.
Again, we have to shrink the plot to prevent clipping. Here I've hard coded the amount to shrink, but you can play around to find a number that works for you or calculate it like in the method above.
import matplotlib.pyplot as plt
import itertools
fig, axes = plt.subplots(3, 4, sharey='row', sharex=True, squeeze=False)
fig.subplots_adjust(hspace=.5)
miny = maxy = 0
for i, a in enumerate(itertools.chain(*axes)):
a.plot([0,4**i], [0,4**i])
a.set_title(i)
miny = min(miny, a.get_ylim()[0])
maxy = max(maxy, a.get_ylim()[1])
# add a big axes, hide frame
# set ylim to match the largest range of any subplot
ax_invis = fig.add_subplot(111, frameon=False)
ax_invis.set_ylim([miny, maxy])
# hide tick and tick label of the big axis
plt.tick_params(labelcolor='none', top=False, bottom=False, left=False, right=False)
plt.xlabel("common X")
plt.ylabel("common Y")
# shrink plot to prevent clipping
plt.subplots_adjust(left=0.15)
plt.show()
This can be done without regex:
>>> string = "Special $#! characters spaces 888323"
>>> ''.join(e for e in string if e.isalnum())
'Specialcharactersspaces888323'
You can use str.isalnum
:
S.isalnum() -> bool Return True if all characters in S are alphanumeric and there is at least one character in S, False otherwise.
If you insist on using regex, other solutions will do fine. However note that if it can be done without using a regular expression, that's the best way to go about it.
I'll have to add an answer here, because the other answers are either not covering my case or are needlessly complicated.
I use github with other developers and I just want all the local branches whose remotes were (possibly merged and) deleted from a github PR to be deleted in one go from my machine. No, things like git branch -r --merged
don't cover the branches that were not merged locally, or the ones that were not merged at all (abandoned) etc, so a different solution is needed.
Anyway, the first step I got it from other answers:
git fetch --prune
A dry run of git remote prune origin
seemed like it would do the same thing in my case, so I went with the shortest version to keep it simple.
Now, a git branch -v
should mark the branches whose remotes are deleted as [gone]
.
Therefore, all I need to do is:
git branch -v|grep \\[gone\\]|awk '{print $1}'|xargs -I{} git branch -D {}
As simple as that, it deletes everything I want for the above scenario.
The less common xargs
syntax is so that it also works on Mac & BSD in addition to Linux.
Careful, this command is not a dry run so it will force-delete all the branches marked as [gone]
. Obviously, this being git nothing is gone forever, if you see branches deleted that you remember you wanted kept you can always undelete them (the above command will have listed their hash on deletion, so a simple git checkout -b <branch> <hash>
.
Edit: Just add this alias to your .bashrc/.bash_profile, the two commands made into one and I updated the second to work on all shells:
alias old_branch_delete='git fetch -p && git branch -vv | awk "/: gone]/{print \$1}" | xargs git branch -D'
Wrote a tutorial so that you can animate your activity's in and out,
