You can use jsoup or wffweb (HTML5) based.
Sample code for jsoup:-
Document doc = Jsoup.parse("<html></html>");
doc.body().addClass("body-styles-cls");
doc.body().appendElement("div");
System.out.println(doc.toString());
prints
<html>
<head></head>
<body class=" body-styles-cls">
<div></div>
</body>
</html>
Sample code for wffweb:-
Html html = new Html(null) {{
new Head(this);
new Body(this,
new ClassAttribute("body-styles-cls"));
}};
Body body = TagRepository.findOneTagAssignableToTag(Body.class, html);
body.appendChild(new Div(null));
System.out.println(html.toHtmlString());
//directly writes to file
html.toOutputStream(new FileOutputStream("/home/user/filepath/filename.html"), "UTF-8");
prints (in minified format):-
<html>
<head></head>
<body class="body-styles-cls">
<div></div>
</body>
</html>
An Identifying relationship specifies that a child object cannot exist without the parent object
Non-identifying relationships specifies a regular association between objects, 1:1 or 1:n cardinality.
Non-identifying relationships can be specified as optional where a parent is not required or mandatory where a parent is required by setting the parent table cardinality...
You can use the IPython.display.clear_output to clear the output as mentioned in cel's answer. I would add that for me the best solution was to use this combination of parameters to print without any "shakiness" of the notebook:
from IPython.display import clear_output
for i in range(10):
clear_output(wait=True)
print(i, flush=True)
It is always dependent on where is your html file that refers to the path of the static resource (in this case the image).
Example A:
src
|__assests
|__images
|__myimage.png
|__yourmodule
|__yourpage.html
As you can see, yourpage.html is one folder away from the root (src folder), for this reason it needs one amount of ../ to go back to the root then you can walk to the image from root:
<img class="img-responsive" src="../assests/images/myimage.png">
Example B:
src
|__assests
|__images
|__myimage.png
|__yourmodule
|__yoursubmodule
|__yourpage.html
Here you have to go u in the tree by 2 folders:
<img class="img-responsive" src="../../assests/images/myimage.png">
public static class EnumEx
{
public static T GetValueFromDescription<T>(string description) where T : Enum
{
foreach(var field in typeof(T).GetFields())
{
if (Attribute.GetCustomAttribute(field,
typeof(DescriptionAttribute)) is DescriptionAttribute attribute)
{
if (attribute.Description == description)
return (T)field.GetValue(null);
}
else
{
if (field.Name == description)
return (T)field.GetValue(null);
}
}
throw new ArgumentException("Not found.", nameof(description));
// Or return default(T);
}
}
Usage:
var panda = EnumEx.GetValueFromDescription<Animal>("Giant Panda");
Thank you for the suggested solutions! Unfortunately, none of them worked for my case: receiving a list of CLOB objects from Oracle database through JPA - Hibernate, using a native query.
All of the proposed approaches gave me either a ClassCastException or just returned java Proxy object (which deeply inside contained the desired Clob).
So my solution is the following (based on several above approaches):
Query sqlQuery = manager.createNativeQuery(queryStr);
List resultList = sqlQuery.getResultList();
for ( Object resultProxy : resultList ) {
String unproxiedClob = unproxyClob(resultProxy);
if ( unproxiedClob != null ) {
resultCollection.add(unproxiedClob);
}
}
private String unproxyClob(Object proxy) {
try {
BeanInfo beanInfo = Introspector.getBeanInfo(proxy.getClass());
for (PropertyDescriptor property : beanInfo.getPropertyDescriptors()) {
Method readMethod = property.getReadMethod();
if ( readMethod.getName().contains("getWrappedClob") ) {
Object result = readMethod.invoke(proxy);
return clobToString((Clob) result);
}
}
}
catch (InvocationTargetException | IntrospectionException | IllegalAccessException | SQLException | IOException e) {
LOG.error("Unable to unproxy CLOB value.", e);
}
return null;
}
private String clobToString(Clob data) throws SQLException, IOException {
StringBuilder sb = new StringBuilder();
Reader reader = data.getCharacterStream();
BufferedReader br = new BufferedReader(reader);
String line;
while( null != (line = br.readLine()) ) {
sb.append(line);
}
br.close();
return sb.toString();
}
Hope this will help somebody!
Dictionary
is probably the closest. System.Collections.Generic.Dictionary
implements the System.Collections.Generic.IDictionary
interface (which is similar to Java's Map
interface).
Some notable differences that you should be aware of:
put
and get
methods for setting/getting items
myMap.put(key, value)
MyObject value = myMap.get(key)
[]
indexing for setting/getting items
myDictionary[key] = value
MyObject value = myDictionary[key]
null
keys
HashMap
allows null keysDictionary
throws an ArgumentNullException
if you try to add a null keyHashMap
will replace the existing value with the new one.Dictionary
will replace the existing value with the new one if you use []
indexing. If you use the Add
method, it will instead throw an ArgumentException
.HashMap
will return null.Dictionary
will throw a KeyNotFoundException
. You can use the TryGetValue
method instead of the []
indexing to avoid this:MyObject value = null;
if (!myDictionary.TryGetValue(key, out value)) { /* key doesn't exist */ }
Dictionary
's has a ContainsKey
method that can help deal with the previous two problems.
To test if the POST variable has an element called 'userID' you would be better off using array_key_exists .. which actually tests for the existence of the array key not whether its value has been set .. a subtle and probably only semantic difference, but it does improve readability.
and right now your $uid is being set to a boolean value depending whether $__POST['userID'] is set or not ... If I recall from memory you might want to try ...
$uid = (array_key_exists('userID', $_POST)?$_POST['userID']:'guest';
Then you can use an identifiable 'guest' user and render your code that much more readable :)
Another point re isset() even though it is unlikely to apply in this scenario, it's worth remembering if you don't want to get caught out later ... an array element can be legitimately set to NULL ... i.e. it can exist, but be as yet unpopulated, and this could be a valid, acceptable, and testable condition. but :
a = array('one'=>1, 'two'=>null, 'three'=>3);
isset(a['one']) == true
isset(a['two']) == false
array_key_exists(a['one']) == true
array_key_exists(a['two']) == true
Bw sure you know which function you want to use for which purpose.
grep LMN20113456 LMN2011*
or if you want to search recursively through subdirectories:
find . -type f -name 'LMN2011*' -exec grep LMN20113456 {} \;
If you have a SSHClient, you can also use open_sftp()
:
import paramiko
# lets say you have SSH client...
client = paramiko.SSHClient()
sftp = client.open_sftp()
# then you can use upload & download as shown above
...
The tail
program can do this:
ls -lart | tail -n +2
The -n +2
means “start passing through on the second line of output”.
Grepping the URL before and after might give you some peace of mind:
svn info | grep URL
URL: svn://svnrepo.rz.mycompany.org/repos/trunk/DataPortal
Relative URL: (...doesn't matter...)
And checking on your version (to be >1.7) to ensure, svn relocate
is the right thing to use:
svn --version
Lastly, adding to the above, if your repository url change also involves a change of protocol you might need to state the before and after url (also see here)
svn relocate svn://svnrepo.rz.mycompany.org/repos/trunk/DataPortal
https://svngate.mycompany.org/svn/repos/trunk/DataPortal
All in one single line of course.Thereafter, get the good feeling, that all went smoothly:
svn info | grep URL:
If you feel like it, a bit more of self-assurance, the new svn repo URL is connected and working:
svn status --show-updates
svn diff
You cannot use || operators in between 2 case. But you can use multiple case values without using a break between them. The program will then jump to the respective case and then it will look for code to execute until it finds a "break". As a result these cases will share the same code.
switch(value)
{
case 0:
case 1:
// do stuff for if case 0 || case 1
break;
// other cases
default:
break;
}
Make sure to use the !important attribute. This dramatically increases the likelihood your styles are retained when printed.
#example1 {
background:url(image.png) no-repeat !important;
}
#example2 {
background-color: #123456 !important;
}

I just had this issue. So there are a few approaches. The first is that new browsers support the
var formData = new FormData();
Follow this link to a blog with info about how support is limited to modern browsers but otherwise it totally solves this issue.
Otherwise you can post the form to an iframe using the target attribute. When you post the form be sure to set the target to an iframe with its display property set to none. The target is the name of the iframe. (Just so you know.)
I hope this helps
I am a beginner so here is a beginners answer. The if in the for loop gives i which can then be used however needed such as Numbers[i] in another vector. Most is fluff for examples sake, the for/if really says it all.
int main(){
vector<string>names{"Sara", "Harold", "Frank", "Taylor", "Sasha", "Seymore"};
string req_name;
cout<<"Enter search name: "<<'\n';
cin>>req_name;
for(int i=0; i<=names.size()-1; ++i) {
if(names[i]==req_name){
cout<<"The index number for "<<req_name<<" is "<<i<<'\n';
return 0;
}
else if(names[i]!=req_name && i==names.size()-1) {
cout<<"That name is not an element in this vector"<<'\n';
} else {
continue;
}
}
SecretKeySpec
expects a key, not a password. See belowThe problem is number 1: you are passing the password instead of the key.
AES only supports key sizes of 16, 24 or 32 bytes. You either need to provide exactly that amount or you derive the key from what you type in.
There are different ways to derive the key from a passphrase. Java provides a PBKDF2 implementation for such a purpose.
I used erickson's answer to paint a complete picture (only encryption, since the decryption is similar, but includes splitting the ciphertext):
SecureRandom random = new SecureRandom();
byte[] salt = new byte[16];
random.nextBytes(salt);
KeySpec spec = new PBEKeySpec("password".toCharArray(), salt, 65536, 256); // AES-256
SecretKeyFactory f = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
byte[] key = f.generateSecret(spec).getEncoded();
SecretKeySpec keySpec = new SecretKeySpec(key, "AES");
byte[] ivBytes = new byte[16];
random.nextBytes(ivBytes);
IvParameterSpec iv = new IvParameterSpec(ivBytes);
Cipher c = Cipher.getInstance("AES/CBC/PKCS5Padding");
c.init(Cipher.ENCRYPT_MODE, keySpec, iv);
byte[] encValue = c.doFinal(valueToEnc.getBytes());
byte[] finalCiphertext = new byte[encValue.length+2*16];
System.arraycopy(ivBytes, 0, finalCiphertext, 0, 16);
System.arraycopy(salt, 0, finalCiphertext, 16, 16);
System.arraycopy(encValue, 0, finalCiphertext, 32, encValue.length);
return finalCiphertext;
Other things to keep in mind:
AES
is not appropriate in such a case, because different JVMs/JCE providers may use different defaults for mode of operation and padding. Use AES/CBC/PKCS5Padding
. Don't use ECB mode, because it is not semantically secure.cipherInstance.getIV()
.Using LIKE:
SELECT *
FROM TABLE
WHERE column LIKE '%cats%' --case-insensitive
It turns out this is 100% possible, though a little hacky.
If you want it to work on Android you need to use this format:
<a href="sms:/* phone number here */?body=/* body text here */">Link</a>
If you want it to work on iOS, you need this:
<a href="sms:/* phone number here */;body=/* body text here */">Link</a>
Live demo here: http://bradorego.com/test/sms.html (note the "Phone and ?body" and "Phone and ;body" should autofill both the to: field and the body text. View the source for more info)
UPDATE:
Apparently iOS8 had to go and change things on us, so thanks to some of the other commenters/responders, there's a new style for iOS:
<a href="sms:/* phone number here */&body=/* body text here */">Link</a>
(phone number is optional)
scanf("%s",str)
scans only until it finds a whitespace character. With the input "A 1"
, it will scan only the first character, hence s2
points at the garbage that happened to be in str
, since that array wasn't initialised.
I think this is a file problem, you simple saved your file in 1-byte encoding like latin-1. Google up your editor and how to set files to utf-8.
I wonder why there are editors that don't default to utf-8.
Install setuptools
and try again.
try command:
sudo apt-get install -y python-setuptools
Not sure if this solution works for you or not but just want to heads you up on compiler and build tools version compatibility issues.
This could be because of Java and Gradle version mismatch.
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
Gradle 4.4 is compatible with only Java 7 and 8. So, point your global variable JAVA_HOME to Java 7 or 8.
In mac, add below line to your ~/.bash_profile
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_191.jdk/Contents/Home
You can have multiple java versions. Just change the JAVA_HOME path based on need. You can do it easily, check this
VPNs can sometimes cause this error as well, if they provide some type of auto-blocking. Disabling the VPN worked for my case.
Well in order to do this, you are not limited with the Class
abstraction of ES6. Accessing the parent constructor's prototype methods is possible through the __proto__
property (I am pretty sure there will be fellow JS coders to complain that it's depreciated) which is depreciated but at the same time discovered that it is actually an essential tool for sub-classing needs (especially for the Array sub-classing needs though). So while the __proto__
property is still available in all major JS engines that i know, ES6 introduced the Object.getPrototypeOf()
functionality on top of it. The super()
tool in the Class
abstraction is a syntactical sugar of this.
So in case you don't have access to the parent constructor's name and don't want to use the Class
abstraction you may still do as follows;
function ChildObject(name) {
// call the parent's constructor
ParentObject.call(this, name);
this.myMethod = function(arg) {
//this.__proto__.__proto__.myMethod.call(this,arg);
Object.getPrototypeOf(Object.getPrototypeOf(this)).myMethod.call(this,arg);
}
}
Try using scrolling=no
attribute on the iframe tag. Mozilla also has an overflow-x
and overflow-y
CSS property you may look into.
In terms of the height, you could also try height=100%
on the iframe tag.
SELECT * INTO < new_table > FROM < existing_table > WHERE < clause >
If you don't want to save method into jQuery.fn you can use
[].reverse.call($('li'));
Use DefinePlugin.
The DefinePlugin allows you to create global constants which can be configured at compile time.
new webpack.DefinePlugin(definitions)
plugins: [
new webpack.DefinePlugin({
PRODUCTION: JSON.stringify(true)
})
//...
]
console.log(`Environment is in production: ${PRODUCTION}`);
When you use git push origin :staleStuff
, it automatically removes origin/staleStuff
, so when you ran git remote prune origin
, you have pruned some branch that was removed by someone else. It's more likely that your co-workers now need to run git prune
to get rid of branches you have removed.
So what exactly git remote prune
does? Main idea: local branches (not tracking branches) are not touched by git remote prune
command and should be removed manually.
Now, a real-world example for better understanding:
You have a remote repository with 2 branches: master
and feature
. Let's assume that you are working on both branches, so as a result you have these references in your local repository (full reference names are given to avoid any confusion):
refs/heads/master
(short name master
)refs/heads/feature
(short name feature
)refs/remotes/origin/master
(short name origin/master
)refs/remotes/origin/feature
(short name origin/feature
)Now, a typical scenario:
feature
, merges it into master
and removes feature
branch from remote repository.git fetch
(or git pull
), no references are removed from your local repository, so you still have all those 4 references.git remote prune origin
.feature
branch no longer exists, so refs/remotes/origin/feature
is a stale branch which should be removed. refs/heads/feature
, because git remote prune
does not remove any refs/heads/*
references.It is possible to identify local branches, associated with remote tracking branches, by branch.<branch_name>.merge
configuration parameter. This parameter is not really required for anything to work (probably except git pull
), so it might be missing.
(updated with example & useful info from comments)
Just thought i might add
RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
would be the .htaccess and be sure to edit your application/config.php variable in the following manner:
replace
$config['uri_protocol'] = “AUTO”
with
$config['uri_protocol'] = “REQUEST_URI”
I'm posting this here, because I've spent like 3 and 4 hours on it, and I've only found answers like those one above, that say do add the executionTime
, but it doesn't solve the problem in the case that you're using ASP .NET Core. For it, this would work:
At web.config file, add the requestTimeout
attribute at aspNetCore
node.
<system.webServer>
<aspNetCore requestTimeout="00:10:00" ... (other configs goes here) />
</system.webServer>
In this example, I'm setting the value for 10 minutes.
As far as I know, there isn't anything on the HTML specs because browsers aren't supposed to do anything different for these fields. They just send them as they normally do and PHP is the one that does the parsing into an array, as do other languages.
neither fgets nor getchar works to solve the problem. the only workaround is keeping a space before %c while using scanf scanf(" %c",ch); // will only work
In the follwing fgets also not work..
char line[256];
char ch;
int i;
printf("Enter a num : ");
scanf("%d",&i);
printf("Enter a char : ");
if (fgets(line, sizeof line, stdin) == NULL) {
printf("Input error.\n");
exit(1);
}
ch = line[0];
printf("Character read: %c\n", ch);

Thanks for all the replies. I went through all of them and came up with a function that gives the first an last index of each occurrence of the 'needle' substring . I am posting it here in case it will help someone.
Please note, it is not the same as the original request for only the beginning of each occurrence. It suits my usecase better because you don't need to keep the needle length.
function findRegexIndices(text, needle, caseSensitive){
var needleLen = needle.length,
reg = new RegExp(needle, caseSensitive ? 'gi' : 'g'),
indices = [],
result;
while ( (result = reg.exec(text)) ) {
indices.push([result.index, result.index + needleLen]);
}
return indices

I had this same issue with a project and some data files that I wasn't able to move inside the repo context for HIPAA reasons. I ended up using 2 Dockerfiles. One builds the main application without the stuff I needed outside the container and publishes that to internal repo. Then a second dockerfile pulls that image and adds the data and creates a new image which is then deployed and never stored anywhere. Not ideal, but it worked for my purposes of keeping sensitive information out of the repo.
I had a similar issue from the console after building a Jar in Intellij. Using the Java configuration to update to a newer version (Windows -> Configure Java -> Update -> Update Now) didn't work and stuck at version 1.8 (Java 8).
To switch to a more recent version locally I had to install the Java 15 JDK from https://www.oracle.com/uk/java/technologies/javase-jdk15-downloads.html and add that to my Java runtime environment settings.
You might also think about taking a different approach, and replacing the call to the network resource with a stub or mock object. Using Sinon, you can decouple the app from the network service, focusing your development efforts.

if you want to ask the user number of lines first:
//array to save line by line
let xInputs = [];
const getInput = async (resolve)=>{
const readline = require('readline').createInterface({
input: process.stdin,
output: process.stdout,
});
readline.on('line',(line)=>{
readline.close();
xInputs.push(line);
resolve(line);
})
}
const getMultiInput = (numberOfInputLines,callback)=>{
let i = 0;
let p = Promise.resolve();
for (; i < numberOfInputLines; i++) {
p = p.then(_ => new Promise(resolve => getInput(resolve)));
}
p.then(()=>{
callback();
});
}
//get number of lines
const readline = require('readline').createInterface({
input: process.stdin,
output: process.stdout,
terminal: false
});
readline.on('line',(line)=>{
getMultiInput(line,()=>{
//get here the inputs from xinputs array
});
readline.close();
})

Using Javascript's es6 or node, you can do the following:
var [a,b,c,d] = [0,1,2,3]
And if you want to easily print multiple variables in a single line, just do this:
console.log(a, b, c, d)
0 1 2 3
This is similar to @alex gray 's answer here, but this example is in Javascript instead of CoffeeScript.
Note that this uses Javascript's array destructuring assignment
Use %in%
as follows
A$C %in% B$C
Which will tell you which values of column C of A are in B.
What is returned is a logical vector. In the specific case of your example, you get:
A$C %in% B$C
# [1] TRUE FALSE TRUE TRUE
Which you can use as an index to the rows of A
or as an index to A$C
to get the actual values:
# as a row index
A[A$C %in% B$C, ] # note the comma to indicate we are indexing rows
# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4 # returns all values of A$C that are in B$C
We can negate it too:
A$C[!A$C %in% B$C]
[1] 2 # returns all values of A$C that are NOT in B$C
2 %in% B$C # "is the value 2 in B$C ?"
# FALSE
A$C[2] %in% B$C # "is the 2nd element of A$C in B$C ?"
# FALSE
I could achieve a button using jQueryMobile with following code:
<label for="ppt" data-role="button" data-inline="true" data-mini="true" data-corners="false">Upload</label>
<input id="ppt" type="file" name="ppt" multiple data-role="button" data-inline="true" data-mini="true" data-corners="false" style="opacity: 0;"/>
Above code creates a "Upload" button (custom text). On click of upload button, file browse is launched. Tested with Chrome 25 & IE9.
I had a similar problem when running my solution from VS2012:
Unable to launch the IIS Express Web server.
The start URL specified is not valid. https://localhost:44301/
I had the incorrect project selected as Startup Project. I made the Cloud project the Startup (right click on project -> Set as Startup Project) and everything started working fine.
When solving Stacking modals scrolls the main page when one is closed i found that newer versions of Bootstrap (at least since version 3.0.3) do not require any additional code to stack modals.
You can add more than one modal (of course having a different ID) to your page. The only issue found when opening more than one modal will be that closing one remove the modal-open
class for the body selector.
You can use the following Javascript code to re-add the modal-open
:
$('.modal').on('hidden.bs.modal', function (e) {
if($('.modal').hasClass('in')) {
$('body').addClass('modal-open');
}
});
In the case that do not need the backdrop effect for the stacked modal you can set data-backdrop="false"
.
Version 3.1.1. fixed Fix modal backdrop overlaying the modal's scrollbar, but the above solution seems also to work with earlier versions.
The WiX project I was using was hard-set in the configuration manager for x64
across the board. When making the Custom Action project for the solution, it defaulted everything to x86
within the .csproj
file. So I unloaded the project, edited it by changing all x86
to x64
, saved, reloaded, and was good to go after that.
I don't understand why I had to do this. The configuration manager was set to build as x64, but just wouldn't get set in the csproj
file :(
if you're just looking to make sure the individual parts of the date stay the same for display purposes, *this appears to work, even when I change my timezone:
var doo = new Date("2011-09-24 00:00:00")
just add the zeros in there.
In my code I do this:
let dateForDisplayToUser =
new Date( `${YYYYMMDDdateStringSeparatedByHyphensFromAPI} 00:00:00` )
.toLocaleDateString(
'en-GB',
{ day: 'numeric', month: 'short', year: 'numeric' }
)
And I switch around my timezone on my computer and the date stays the same as the yyyy-mm-dd date string I get from the API.
But am I missing something/is this a bad idea ?
*at least in chrome. This Doesn't work in Safari ! as of this writing
The input shape you have defined is the shape of a single sample. The model itself expects some array of samples as input (even if its an array of length 1).
Your output really should be 4-d, with the 1st dimension to enumerate the samples. i.e. for a single image you should return a shape of (1, 32, 32, 3).
You can find more information here under "Convolution2D"/"Input shape"
Edit: Based on Danny's comment below, if you want a batch size of 1, you can add the missing dimension using this:
image = np.expand_dims(image, axis=0)
Great Answer Lain!
There were a couple things I did to make this work in a broader set of devices. At the end I will list the clients I tested on.
I added a new build constructor that did not contain the parameter attachments and did not use MimeMultipart("mixed"). There is no need for mixed if you are sending only inline images.
public Multipart build(String messageText, String messageHtml, List<URL> messageHtmlInline) throws MessagingException {
final Multipart mpAlternative = new MimeMultipart("alternative");
{
// Note: MUST RENDER HTML LAST otherwise iPad mail client only renders
// the last image and no email
addTextVersion(mpAlternative,messageText);
addHtmlVersion(mpAlternative,messageHtml, messageHtmlInline);
}
return mpAlternative;
}
In addTextVersion method I added charset when adding content this probably could/should be passed in, but I just added it statically.
textPart.setContent(messageText, "text/plain");
to
textPart.setContent(messageText, "text/plain; charset=UTF-8");
The last item was adding to the addImagesInline method. I added setting the image filename to the header by the following code. If you don't do this then at least on Android default mail client it will have inline images that have a name of Unknown and will not automatically download them and present in email.
for (URL img : embeded) {
final MimeBodyPart htmlPartImg = new MimeBodyPart();
DataSource htmlPartImgDs = new URLDataSource(img);
htmlPartImg.setDataHandler(new DataHandler(htmlPartImgDs));
String fileName = img.getFile();
fileName = getFileName(fileName);
String newFileName = cids.get(fileName);
boolean imageNotReferencedInHtml = newFileName == null;
if (imageNotReferencedInHtml) continue;
htmlPartImg.setHeader("Content-ID", "<"+newFileName+">");
htmlPartImg.setDisposition(BodyPart.INLINE);
**htmlPartImg.setFileName(newFileName);**
parent.addBodyPart(htmlPartImg);
}
So finally, this is the list of clients I tested on. Outlook 2010, Outlook Web App, Internet Explorer 11, Firefox, Chrome, Outlook using Apple’s native app, Email going through Gmail - Browser mail client, Internet Explorer 11, Firefox, Chrome, Android default mail client, osx IPhone default mail client, Gmail mail client on Android, Gmail mail client on IPhone, Email going through Yahoo - Browser mail client, Internet Explorer 11, Firefox, Chrome, Android default mail client, osx IPhone default mail client.
Hope that helps anyone else.
As mentioned in the error, the official manual and the comments:
Replace
public function TSStatus($host, $queryPort)
with
public function __construct($host, $queryPort)
You might consider using the :checked
selector, provided by jQuery. Something like this:
$('.pChk').click(function() {
if( $('.pChk:checked').length > 0 ) {
$("#ProjectListButton").show();
} else {
$("#ProjectListButton").hide();
}
});
You can use os.walk
, and that is probably the easiest solution, but here is another idea to explore:
import sys, os
FILES = False
def main():
if len(sys.argv) > 2 and sys.argv[2].upper() == '/F':
global FILES; FILES = True
try:
tree(sys.argv[1])
except:
print('Usage: {} <directory>'.format(os.path.basename(sys.argv[0])))
def tree(path):
path = os.path.abspath(path)
dirs, files = listdir(path)[:2]
print(path)
walk(path, dirs, files)
if not dirs:
print('No subfolders exist')
def walk(root, dirs, files, prefix=''):
if FILES and files:
file_prefix = prefix + ('|' if dirs else ' ') + ' '
for name in files:
print(file_prefix + name)
print(file_prefix)
dir_prefix, walk_prefix = prefix + '+---', prefix + '| '
for pos, neg, name in enumerate2(dirs):
if neg == -1:
dir_prefix, walk_prefix = prefix + '\\---', prefix + ' '
print(dir_prefix + name)
path = os.path.join(root, name)
try:
dirs, files = listdir(path)[:2]
except:
pass
else:
walk(path, dirs, files, walk_prefix)
def listdir(path):
dirs, files, links = [], [], []
for name in os.listdir(path):
path_name = os.path.join(path, name)
if os.path.isdir(path_name):
dirs.append(name)
elif os.path.isfile(path_name):
files.append(name)
elif os.path.islink(path_name):
links.append(name)
return dirs, files, links
def enumerate2(sequence):
length = len(sequence)
for count, value in enumerate(sequence):
yield count, count - length, value
if __name__ == '__main__':
main()
You might recognize the following documentation from the TREE command in the Windows terminal:
Graphically displays the folder structure of a drive or path.
TREE [drive:][path] [/F] [/A]
/F Display the names of the files in each folder.
/A Use ASCII instead of extended characters.
In case that you're interested in specific lines, use a result-array:
declare RESULT=($(./myscript)) # (..) = array
echo "First line: ${RESULT[0]}"
echo "Second line: ${RESULT[1]}"
echo "N-th line: ${RESULT[N]}"
When you run a shell script, it's done in a sub-shell so it cannot affect the parent shell's environment. You want to source the script by doing:
. ./setfoo.sh
This executes it in the context of the current shell, not as a sub shell.
From the bash man page:
. filename [arguments]
source filename [arguments]Read and execute commands from filename in the current shell environment and return the exit status of the last command executed from filename.
If filename does not contain a slash, file names in PATH are used to find the directory containing filename.
The file searched for in PATH need not be executable. When bash is not in POSIX mode, the current directory is searched if no file is found in PATH.
If the sourcepath option to the shopt builtin command is turned off, the PATH is not searched.
If any arguments are supplied, they become the positional parameters when filename is executed.
Otherwise the positional parameters are unchanged. The return status is the status of the last command exited within the script (0 if no commands are executed), and false if filename is not found or cannot be read.
I had a similar issue.
The problem was, on Windows, in the index, the file was added in a case different from what was in the unstaged area. For example, in the index, the file was name xx.txt
and in the unstaged area, the file was names Xx.txt
.
Removed the file with the incorrect case from the index (xx.txt
). Then, I have been able to add the file with the correct case (Xx.txt
).
See the javadoc. It's an inclusive index for the first argument and exclusive for the second.
Your debut
and fin
values are floating point values, not integers, because taille
is a float.
Make those values integers instead:
item = plateau[int(debut):int(fin)]
Alternatively, make taille
an integer:
taille = int(sqrt(len(plateau)))
You can use Process.GetProcesses()
to get the currently running processes, then Process.Kill()
to kill a process.

return bean.getFreePhysicalMemorySize();

On Mac OS for IntelliJ v12, shut down the IDE, and then you can execute:
rm -rf ~/Library/Preferences/IdeaIC12/*
Restart the IDE, or open a pom.xml of your choosing. You will be asked whether you want to import the preferences from an existing IntelliJ instance. Select the "No, I do not have a previous IntelliJ version" radio button.
Short answer:

You should learn the basics of crontab
.
Edit the cron by command crontab -e
and then ^ (CTRL) + X then Y and finally press ENTER (return) on mac to save the file. You can check the new crons have been installed of not by crontab -l
A crontab file has five fields for specifying mins, hours, the day of the month, month, and the day of the week followed by the command to be run at that interval.
* * * * * command to be executed
- - - - -
| | | | |
| | | | +----- day of week (0-6) (Sunday=0)
| | | +------- month (1-12)
| | +--------- day of month (1-31)
| +----------- hour (0-23)
+------------- min (0-59)
*
in the value field above means all legal values as in braces for that column.
Here, I wrote a detailed post about it: Setup Cron in Unix

The easiest solution works for me is simply put in
$ export JAVA_HOME=$(/usr/libexec/java_home)

I had the same problem, here's how I solved it. Following the first section of this very excellent Django tutorial, I did the following:
python manage.py startapp new_app
settings.py
file, adding the following to the list of INSTALLED_APPS
: 'new_app',
new_app
package named new_app_tags
.{% extends 'base_template_name.html' %}
: {% load new_app_tags %}
new_app_tags
module file, create a custom template tag (see below).{% multiply_by_two | "5.0" %}
Example from step 5 above:
from django import template
register = template.Library()
@register.simple_tag
def multiply_by_two(value):
return float(value) * 2.0
If you don't mind leaving pure C# and going for WinApi calls, then you might want to consider the PathIsDirectoryEmpty() function. According to the MSDN, the function:
Returns TRUE if pszPath is an empty directory. Returns FALSE if pszPath is not a directory, or if it contains at least one file other than "." or "..".
That seems to be a function which does exactly what you want, so it is probably well optimised for that task (although I haven't tested that).
To call it from C#, the pinvoke.net site should help you. (Unfortunately, it doesn't describe this certain function yet, but you should be able to find some functions with similar arguments and return type there and use them as the basis for your call. If you look again into the MSDN, it says that the DLL to import from is shlwapi.dll
)
See this table.
A 101x101 QR code, with high level error correction, can hold 3248 bits, or 406 bytes. Probably not enough for any meaningful SVG/XML data.
A 177x177 grid, depending on desired level of error correction, can store between 1273 and 2953 bytes. Maybe enough to store something small.
C++11 added alias declarations, which are generalization of typedef
, allowing templates:
template <size_t N>
using Vector = Matrix<N, 1>;
The type Vector<3>
is equivalent to Matrix<3, 1>
.
In C++03, the closest approximation was:
template <size_t N>
struct Vector
{
typedef Matrix<N, 1> type;
};
Here, the type Vector<3>::type
is equivalent to Matrix<3, 1>
.
instead of ng-model you can use this code:
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
template: `<input #box (keyup)="0">
<p>{{box.value}}</p>`,
})
export class AppComponent {}
inside your app.component.ts
Out of curiosity, I wanted to see how Value
performed against Value2
. After about 12 trials of similar processes, I could not see any significant differences in speed so I would always recommend using Value
. I used the below code to run some tests with various ranges.
If anyone sees anything contrary regarding performance, please post.
Sub Trial_RUN()
For t = 0 To 5
TestValueMethod (True)
TestValueMethod (False)
Next t
End Sub
Sub TestValueMethod(useValue2 As Boolean)
Dim beginTime As Date, aCell As Range, rngAddress As String, ResultsColumn As Long
ResultsColumn = 5
'have some values in your RngAddress. in my case i put =Rand() in the cells, and then set to values
rngAddress = "A2:A399999" 'I changed this around on my sets.
With ThisWorkbook.Sheets(1)
.Range(rngAddress).Offset(0, 1).ClearContents
beginTime = Now
For Each aCell In .Range(rngAddress).Cells
If useValue2 Then
aCell.Offset(0, 1).Value2 = aCell.Value2 + aCell.Offset(-1, 1).Value2
Else
aCell.Offset(0, 1).Value = aCell.Value + aCell.Offset(-1, 1).Value
End If
Next aCell
Dim Answer As String
If useValue2 Then Answer = " using Value2"
.Cells(Rows.Count, ResultsColumn).End(xlUp).Offset(1, 0) = DateDiff("S", beginTime, Now) & _
" seconds. For " & .Range(rngAddress).Cells.Count & " cells, at " & Now & Answer
End With

My general understanding is that any object variable (such as a list or a dict, among others) can be modified through its functions. What I believe you are not able to do is reassign the parameter - i.e., assign it by reference within a callable function.
That is consistent with many other languages.
Run the following short script to see how it works:
def func1(x, l1):
x = 5
l1.append("nonsense")
y = 10
list1 = ["meaning"]
func1(y, list1)
print(y)
print(list1)
variable=" Hello..."
print (variable)
print("This is the Test File "+variable)
for integer type ...
variable=" 10"
print (variable)
print("This is the Test File "+str(variable))
The answer that the OP accepted is wildly different from the question I thought was asked. I thought the OP wanted a way to auto-align =
signs or +
signs, similar to the tabularize plugin for vim.
For this task, I found the Columns4Eclipse plugin to be just what I needed.
There is a wonderful print_r
implementation for JavaScript in php.js library.
Note, you should also add echo
support in the code.
I think the best way to run this command:
**rake db:reset** it does db:drop, db:setup
rake db:setup does db:create, db:schema:load, db:seed
You can use this code(Recommended)
MemoryStream objMS = new MemoryStream();
DataTable oDT = new DataTable();//Your DataTable which you want to convert
oDT.WriteXml(objMS);
objMS.Position = 0;
XPathDocument result = new XPathDocument(objMS);
This is another way but first ex. is recommended
StringWriter objSW = new StringWriter();
DataTable oDt = new DataTable();//Your DataTable which you want to convert
oDt.WriteXml(objSW);
string result = objSW.ToString();
You can also use get_object_or_404(), it will raise a Http404
if the object wasn't found:
user_pass = log_in(request.POST) #form class
if user_pass.is_valid():
cleaned_info = user_pass.cleaned_data
user_object = get_object_or_404(User, email=cleaned_info['username'])
# User object found, you are good to go!
...
In Python 2.6 or greater it's a bit cleaner:
except Exception as e: print(e)
In older versions it's still quite readable:
except Exception, e: print e
The if statement uses the results of a logical expression to decide if one of two code blocks will be executed.
With this code
if (logical expression) {
code block 1;
} else {
code block 2;
}
if the logical expression is true, only the statements in code block 1 will be executed; if false, only the statements in code block 2.
In the case that there are multiple similar tests to be done (for instance if we are testing a number to be less than zero, equal to zero or more than zero) then the second test can be placed as the first statement of the else code block.
if (logical expression 1) {
code block 1;
} else {
if (logical expression 2) {
code block 2;
} else {
code block 3;
}
}
In this case, code block 1 is executed if logical expression 1 is true; code block 2 if logical expression 1 is false and logical expression 2 is true; code block 3 if both logical expressions are false.
Obviously this can be repeated with another if statement as the first statement of code block 3.
The else if statement is simply a reformatted version of this code.
if (logical expression 1) {
code block 1;
} else if (logical expression 2) {
code block 2;
} else {
code block 3;
}
Based on this article, I have put together the following snippet that provides some very basic functionality:
<div id = "container"></div>
<script>
function setPDFHeight(){
$("#pdfObject")[0].height = $("#pdfObject")[0].offsetHeight;
}
$('#container').append('<div align="center" style="width: 100%; height:100%; overflow: auto !important; -webkit-overflow-scrolling: touch !important;">\
<object id="pdfObject" width="100%" height="1000000000000" align="center" data="content/lessons/12/t.pdf" type="application/pdf" onload="setPDFHeight()">You have no plugin installed</object></div>');
</script>
Obviously it is far from perfect (given that it practically expands your page height to infinity), but it's the only viable workaround I've found so far.
You can use either File.Copy(oldFilePath, newFilePath) method or other way is, read file using StreamReader into an string and then use StreamWriter to write the file to destination location.
Your code might look like this :
StreamReader reader = new StreamReader("C:\foo.txt");
string fileContent = reader.ReadToEnd();
StreamWriter writer = new StreamWriter("D:\bar.txt");
writer.Write(fileContent);
You can add exception handling code...
Yes it is possible using ProcessBuilder.
ProcessBuilder example:
import java.io.*;
import java.util.*;
public class CmdProcessBuilder {
public static void main(String args[])
throws InterruptedException,IOException
{
List<String> command = new ArrayList<String>();
command.add(args[0]);
ProcessBuilder builder = new ProcessBuilder(command);
Map<String, String> environ = builder.environment();
final Process process = builder.start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
System.out.println("Program terminated!");
}
}
Check these examples:

There are two approaches in the standard library. One is to use java.text.DecimalFormat. The other more cryptic methods (String.format, PrintStream.printf, etc) based around java.util.Formatter should keep C programmers happy(ish).

I had the same problem yet. After comparing several modules that seem to have this feature, I decided to do it myself, it's simpler than I thought.
gist: https://gist.github.com/deemstone/8279565
var fetchBlock = lineByline(filepath, onEnd);
fetchBlock(function(lines, start){ ... }); //lines{array} start{int} lines[0] No.
It cover the file opened in a closure, that fetchBlock()
returned will fetch a block from the file, end split to array (will deal the segment from last fetch).
I've set the block size to 1024 for each read operation. This may have bugs, but code logic is obvious, try it yourself.
if the database is InnoDB you dont need to do joins in deletion. only
DELETE FROM spawnlist WHERE spawnlist.type = "monster";
can be used to delete the all the records that linked with foreign keys in other tables, to do that you have to first linked your tables in design time.
CREATE TABLE IF NOT EXIST spawnlist (
npc_templateid VARCHAR(20) NOT NULL PRIMARY KEY
)ENGINE=InnoDB;
CREATE TABLE IF NOT EXIST npc (
idTemplate VARCHAR(20) NOT NULL,
FOREIGN KEY (idTemplate) REFERENCES spawnlist(npc_templateid) ON DELETE CASCADE
)ENGINE=InnoDB;
if you uses MyISAM you can delete records joining like this
DELETE a,b
FROM `spawnlist` a
JOIN `npc` b
ON a.`npc_templateid` = b.`idTemplate`
WHERE a.`type` = 'monster';
in first line i have initialized the two temp tables for delet the record, in second line i have assigned the existance table to both a and b but here i have linked both tables together with join keyword, and i have matched the primary and foreign key for both tables that make link, in last line i have filtered the record by field to delete.
You can also use a service called Filepicker
which will store your image to their servers and Filepicker which is now called Filestack, will provide you with a url to the image. You can than store the url to Firebase.
To fix this, I did a reinstall of xcode (This also presented user agreement). I used the following command:
xcode-select --install
Try this way, more efficient and compatible:
SimpleDateFormat time_formatter = new SimpleDateFormat("yyyy-MM-dd_HH:mm:ss.SSS");
String current_time_str = time_formatter.format(System.currentTimeMillis());
//Log.i("test", "current_time_str:" + current_time_str);
November 2019:
onclick="self.close()"
still works in Chrome while Edge gives a warning that must be confirmed before it will close.
On the other hand the solution onclick="window.open('', '_self', ''); window.close();"
works in both.
I like the approach using list.files()
, lapply()
and list2env()
(or fs::dir_ls()
, purrr::map()
and list2env()
). That seems simple and flexible.
Alternatively, you may try the small package {tor} (to-R): By default it imports files from the working directory into a list (list_*()
variants) or into the global environment (load_*()
variants).
For example, here I read all the .csv files from my working directory into a list using tor::list_csv()
:
library(tor)
dir()
#> [1] "_pkgdown.yml" "cran-comments.md" "csv1.csv"
#> [4] "csv2.csv" "datasets" "DESCRIPTION"
#> [7] "docs" "inst" "LICENSE.md"
#> [10] "man" "NAMESPACE" "NEWS.md"
#> [13] "R" "README.md" "README.Rmd"
#> [16] "tests" "tmp.R" "tor.Rproj"
list_csv()
#> $csv1
#> x
#> 1 1
#> 2 2
#>
#> $csv2
#> y
#> 1 a
#> 2 b
And now I load those files into my global environment with tor::load_csv()
:
# The working directory contains .csv files
dir()
#> [1] "_pkgdown.yml" "cran-comments.md" "CRAN-RELEASE"
#> [4] "csv1.csv" "csv2.csv" "datasets"
#> [7] "DESCRIPTION" "docs" "inst"
#> [10] "LICENSE.md" "man" "NAMESPACE"
#> [13] "NEWS.md" "R" "README.md"
#> [16] "README.Rmd" "tests" "tmp.R"
#> [19] "tor.Rproj"
load_csv()
# Each file is now available as a dataframe in the global environment
csv1
#> x
#> 1 1
#> 2 2
csv2
#> y
#> 1 a
#> 2 b
Should you need to read specific files, you can match their file-path with regexp
, ignore.case
and invert
.
For even more flexibility use list_any()
. It allows you to supply the reader function via the argument .f
.
(path_csv <- tor_example("csv"))
#> [1] "C:/Users/LeporeM/Documents/R/R-3.5.2/library/tor/extdata/csv"
dir(path_csv)
#> [1] "file1.csv" "file2.csv"
list_any(path_csv, read.csv)
#> $file1
#> x
#> 1 1
#> 2 2
#>
#> $file2
#> y
#> 1 a
#> 2 b
Pass additional arguments via ... or inside the lambda function.
path_csv %>%
list_any(readr::read_csv, skip = 1)
#> Parsed with column specification:
#> cols(
#> `1` = col_double()
#> )
#> Parsed with column specification:
#> cols(
#> a = col_character()
#> )
#> $file1
#> # A tibble: 1 x 1
#> `1`
#> <dbl>
#> 1 2
#>
#> $file2
#> # A tibble: 1 x 1
#> a
#> <chr>
#> 1 b
path_csv %>%
list_any(~read.csv(., stringsAsFactors = FALSE)) %>%
map(as_tibble)
#> $file1
#> # A tibble: 2 x 1
#> x
#> <int>
#> 1 1
#> 2 2
#>
#> $file2
#> # A tibble: 2 x 1
#> y
#> <chr>
#> 1 a
#> 2 b
After Many attempts in getting this fixed, it was found out that the issue was with Mysql users not being allowed to login
netstat -na | grep -i 3306
If it is listening on all interfaces, then you can assign any of your interfaces to this
$cfg['Servers'][$i]['host'] = 'ANY INTERFACE';
Try to Login using the above IP using the comand line
mysql -u bla -p -h <Above_IP_address>
If this works then your phpmyadmin will also work, If not fix the mysql.user table so that the above command works and allows you to login to mysql.
The more common reason for this message to be printed is because you forgot to include the directory in which the source file resides. As a result, gcc "thinks" this file does not exist.
You can add the directory using the -I argument to gcc.
You want the following:
ALTER TABLE mytable MODIFY mycolumn VARCHAR(255);
Columns are nullable by default. As long as the column is not declared UNIQUE
or NOT NULL
, there shouldn't be any problems.
I had an application that used a ListPreference
where the user was required to select the location of where they wanted to save something.
In that app, I scanned /proc/mounts
and /system/etc/vold.fstab
for sdcard mount points. I stored the mount points from each file into two separate ArrayList
s.
Then, I compared one list with the other and discarded items that were not in both lists. That gave me a list of root paths to each sdcard.
From there, I tested the paths with File.exists()
, File.isDirectory()
, and File.canWrite()
. If any of those tests were false, I discarded that path from the list.
Whatever was left in the list, I converted to a String[]
array so it could be used by the ListPreference
values attribute.
You can view the code here: http://sapienmobile.com/?p=204
#!/usr/bin/env python
# -*- coding: utf-8 -*-
s = u"6Â 918Â 417Â 712"
s = s.replace(u"Â", "")
print s
This will print out 6 918 417 712
The query execution happens on all get methods like
$this->db->get('table_name');
$this->db->get_where('table_name',$array);
While last_query contains the last query which was run
$this->db->last_query();
If you want to get query string without execution you will have to do this. Go to system/database/DB_active_rec.php Remove public or protected keyword from these functions
public function _compile_select($select_override = FALSE)
public function _reset_select()
Now you can write query and get it in a variable
$this->db->select('trans_id');
$this->db->from('myTable');
$this->db->where('code','B');
$subQuery = $this->db->_compile_select();
Now reset query so if you want to write another query the object will be cleared.
$this->db->_reset_select();
And the thing is done. Cheers!!! Note : While using this way you must use
$this->db->from('myTable')
instead of
$this->db->get('myTable')
which runs the query.
I would like to suggest a much cleaner way. This will be useful when we have multiple storyboards
1.Create a structure with all your storyboards
struct Storyboard {
static let main = "Main"
static let login = "login"
static let profile = "profile"
static let home = "home"
}
2. Create a UIStoryboard extension like this
extension UIStoryboard {
@nonobjc class var main: UIStoryboard {
return UIStoryboard(name: Storyboard.main, bundle: nil)
}
@nonobjc class var journey: UIStoryboard {
return UIStoryboard(name: Storyboard.login, bundle: nil)
}
@nonobjc class var quiz: UIStoryboard {
return UIStoryboard(name: Storyboard.profile, bundle: nil)
}
@nonobjc class var home: UIStoryboard {
return UIStoryboard(name: Storyboard.home, bundle: nil)
}
}
Give the storyboard identifier as the class name, and use the below code to instantiate
let loginVc = UIStoryboard.login.instantiateViewController(withIdentifier: "\(LoginViewController.self)") as! LoginViewController
To keep the color and prevent an underline on the link:
legend.green-color a{
color:green;
text-decoration: none;
}
No there isn't and it's probably not there, because there are very few valid uses for it. I would think twice before using it. Also, it is indeed easy to create yourself.
Please refer to this discussion about why it's even in .NET.
I guess UnsupportedOperationException
comes close, although it doesn't say the operation is just not implemented, but unsupported even. That could imply no valid implementation is possible. Why would the operation be unsupported? Should it even be there?
Interface segregation or Liskov substitution issues maybe?
If it's work in progress I'd go for ToBeImplementedException
, but I've never caught myself defining a concrete method and then leave it for so long it makes it into production and there would be a need for such an exception.
Here's one way in XSLT 2
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"','''')"/> </xsl:template> </xsl:stylesheet>
Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:variable name="apos">'</xsl:variable> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"',$apos)"/> </xsl:template> </xsl:stylesheet>
That is not possible without intercepting addEventListener
calls and keep track of the listeners or use a library that allows such features unfortunately. It would have been if the listeners collection was accessible but the feature wasn't implemented.
The closest thing you can do is to remove all listeners by cloning the element, which will not clone the listeners collection.
Note: This will also remove listeners on element's children.
var el = document.getElementById('el-id'),
elClone = el.cloneNode(true);
el.parentNode.replaceChild(elClone, el);
Simple first create a class
public class ViewDialog {
public void showDialog(Activity activity, String msg){
final Dialog dialog = new Dialog(activity);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(false);
dialog.setContentView(R.layout.custom_dialogbox_otp);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
TextView text = (TextView) dialog.findViewById(R.id.txt_file_path);
text.setText(msg);
Button dialogBtn_cancel = (Button) dialog.findViewById(R.id.btn_cancel);
dialogBtn_cancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Toast.makeText(getApplicationContext(),"Cancel" ,Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
});
Button dialogBtn_okay = (Button) dialog.findViewById(R.id.btn_okay);
dialogBtn_okay.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Toast.makeText(getApplicationContext(),"Okay" ,Toast.LENGTH_SHORT).show();
dialog.cancel();
}
});
dialog.show();
}
}
then create a custom_dialogbox_otp

Enjoy Coding.
.catch(error => { throw error})
is a no-op. It results in unhandled rejection in route handler.
As explained in this answer, Express doesn't support promises, all rejections should be handled manually:
router.get("/emailfetch", authCheck, async (req, res, next) => {
try {
//listing messages in users mailbox
let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
emailFetch = emailFetch.data
res.send(emailFetch)
} catch (err) {
next(err);
}
})
You should normally be able to run a php file (after a successful installation) just by running this command:
$ /path/to/php myfile.php // unix way
C:\php\php.exe myfile.php // windows way
You can read more about running PHP in CLI mode here.
It's worth adding that PHP from version 5.4 onwards is able to run a web server on its own. You can do it by running this code in a folder which you want to serve the pages from:
$ php -S localhost:8000
You can read more about running a PHP in a Web Server mode here.
I know it has been quite sometime that you asked this but, if someone else needs, I did what was saying here " How to upload a project to Github " and after the top answer of this question right here. And after was the top answer was saying here "git error: failed to push some refs to" I don't know what exactly made everything work. But now is working.
Just use a one-cell table inside the div! Just set the cell and table height and with to 100% and you can use the vertical-align.
A one-cell table inside the div handles the vertical-align and is backward compatible back to the Stone Age!
Based on Tim's second edit and this page you could do this:
@echo off
if "%1"=="loop" (
for /l %%f in (1,1,1000000) do (
echo %%f
if exist %%f exit
)
goto :eof
)
cmd /v:on /q /d /c "%0 loop"
echo done
This page suggests a way to use a goto inside a loop, it seems it does work, but it takes some time in a large loop. So internally it finishes the loop before the goto is executed.
<style type="text/css" media="print">
.landscape {
width: 100%;
height: 100%;
margin: 0% 0% 0% 0%; filter: progid:DXImageTransform.Microsoft.BasicImage(Rotation=1);
}
</style>
If you want this style to be applied to a table then create one div tag with this style class and add the table tag within this div tag and close the div tag at the end.
This table will only print in landscape and all other pages will print in portrait mode only. But the problem is if the table size is more than the page width then we may loose some of the rows and sometimes headers also are missed. Be careful.
Have a good day.
Thank you, Naveen Mettapally.
self.tableView.tableHeaderView = segmentedControl;
If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.

Just append #[id of the div you want to scroll to]
to your page url. For example, if I wanted to scroll to the copyright section of this stackoverflow question, the URL would change from
http://stackoverflow.com/questions/9757625/jquery-how-to-scroll-to-certain-anchor-div-on-page-load
to
http://stackoverflow.com/questions/9757625/jquery-how-to-scroll-to-certain-anchor-div-on-page-load#copyright
notice the #copyright

We can solve it in data.table
way with tidyr::repalce_na
function and lapply
library(data.table)
library(tidyr)
setDT(df)
df[,c("a","b","c"):=lapply(.SD,function(x) replace_na(x,0)),.SDcols=c("a","b","c")]
In this way, we can also solve paste columns with NA
string. First, we replace_na(x,"")
,then we can use stringr::str_c
to combine columns!
Honestly, the best way to limit files is on the server side. People can spoof file type on the client so taking in the full file name at server transfer time, parsing out the file type, and then returning a message is usually the best bet.
Thinking about it in general, I would strongly consider hiding coordinate system behind well-designed abstraction. Quoting Uncle Bob and his book:
class Point(object)
def setCartesian(self, x, y)
def setPolar(self, rho, theta)
def getX(self)
def getY(self)
def getRho(self)
def setTheta(self)
With interface like that any user of Point class may choose convenient representation, no explicit conversions will be performed. All this ugly sines, cosines etc. will be hidden in one place. Point class. Only place where you should care which representation is used in computer memory.
Check out this list of lightbox plugins, depending on your exact requirements you can find the plugin of your choice from there easier than asking here. If you need a specific lightbox which can do just about anything and everything, try NyroModal.
Assume time column is in timestamp integer msec format
1 day = 86400000 ms
Here you go:

df['time'] = df['time'].values.astype(dtype='datetime64[ms]') # for msec format
df['time'] = (df['time']/day_divider).values.astype(dtype='datetime64[D]') # for day format
In 1985, individuals from companies throughout the computer industry joined together to develop the POSIX (Portable Operating System Interface for Computer Environments) standard, which is based largely on the UNIX System V Interface Definition (SVID) and other earlier standardization efforts. These efforts were spurred by the U.S. government, which needed a standard computing environment to minimize its training and procurement costs. Released in 1988, POSIX is a group of IEEE standards that define the API, shell, and utility interfaces for an operating system. Although aimed at UNIX-like systems, the standards can apply to any compatible operating system. Now that these stan- dards have gained acceptance, software developers are able to develop applications that run on all conforming versions of UNIX, Linux, and other operating systems.

First add the collections and then apply lookup on these collections. Don't use $unwind
as unwind will simply separate all the documents of each collections. So apply simple lookup and then use $project
for projection.
Here is mongoDB query:
db.userInfo.aggregate([
{
$lookup: {
from: "userRole",
localField: "userId",
foreignField: "userId",
as: "userRole"
}
},
{
$lookup: {
from: "userInfo",
localField: "userId",
foreignField: "userId",
as: "userInfo"
}
},
{$project: {
"_id":0,
"userRole._id":0,
"userInfo._id":0
}
} ])
Here is the output:
/* 1 */ {
"userId" : "AD",
"phone" : "0000000000",
"userRole" : [
{
"userId" : "AD",
"role" : "admin"
}
],
"userInfo" : [
{
"userId" : "AD",
"phone" : "0000000000"
}
] }
Thanks.
Just a piece of advice. Instead of writing
for (int i=0; i=((Main.size())-1); i++) {
cout << Main[i] << '\n';
}
as suggested above, write a:
for (vector<double>::iterator it=Main.begin(); it!=Main.end(); it++) {
cout << *it << '\n';
}
to use iterators. If you have C++11
support, you can declare i
as auto i=Main.begin()
(just a handy shortcut though)
This avoids the nasty one-position-out-of-bound error caused by leaving out a -1
unintentionally.
Just another way of doing it.

I know this is a very old question but this is more for someone else who might have the same problem and I think this is more accurate to what was wanted.
SELECT * FROM member WHERE email = (Select email From member Where login_id = [email protected])
This will return all records that have [email protected] as a login_id value.
The top answer is flawed in my opinion. Hopefully, no one is mass importing all of pandas into their namespace with from pandas import *
. Also, the map
method should be reserved for those times when passing it a dictionary or Series. It can take a function but this is what apply
is used for.
So, if you must use the above approach, I would write it like this
df["A1"], df["A2"] = zip(*df["a"].apply(calculate))
There's actually no reason to use zip here. You can simply do this:
df["A1"], df["A2"] = calculate(df['a'])
This second method is also much faster on larger DataFrames
df = pd.DataFrame({'a': [1,2,3] * 100000, 'b': [2,3,4] * 100000})
DataFrame created with 300,000 rows
%timeit df["A1"], df["A2"] = calculate(df['a'])
2.65 ms ± 92.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
%timeit df["A1"], df["A2"] = zip(*df["a"].apply(calculate))
159 ms ± 5.24 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
60x faster than zip
Apply is generally not much faster than iterating over a Python list. Let's test the performance of a for-loop to do the same thing as above
%%timeit
A1, A2 = [], []
for val in df['a']:
A1.append(val**2)
A2.append(val**3)
df['A1'] = A1
df['A2'] = A2
298 ms ± 7.14 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
So this is twice as slow which isn't a terrible performance regression, but if we cythonize the above, we get much better performance. Assuming, you are using ipython:
%load_ext cython
%%cython
cpdef power(vals):
A1, A2 = [], []
cdef double val
for val in vals:
A1.append(val**2)
A2.append(val**3)
return A1, A2
%timeit df['A1'], df['A2'] = power(df['a'])
72.7 ms ± 2.16 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
You can get even greater speed improvements if you use the direct vectorized operations.
%timeit df['A1'], df['A2'] = df['a'] ** 2, df['a'] ** 3
5.13 ms ± 320 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
This takes advantage of NumPy's extremely fast vectorized operations instead of our loops. We now have a 30x speedup over the original.
apply
The above example should clearly show how slow apply
can be, but just so its extra clear let's look at the most basic example. Let's square a Series of 10 million numbers with and without apply
s = pd.Series(np.random.rand(10000000))
%timeit s.apply(calc)
3.3 s ± 57.4 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
Without apply is 50x faster
%timeit s ** 2
66 ms ± 2 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
You are not comparing dates. You are comparing strings. In the world of string comparisons, 09/17/2015
> 01/02/2016
because 09
> 01
. You need to either put your date in a comparable string format or compare DateTime
objects which are comparable.
<?php
$date_now = date("Y-m-d"); // this format is string comparable
if ($date_now > '2016-01-02') {
echo 'greater than';
}else{
echo 'Less than';
}
Or
<?php
$date_now = new DateTime();
$date2 = new DateTime("01/02/2016");
if ($date_now > $date2) {
echo 'greater than';
}else{
echo 'Less than';
}
The literal answer to your question (to do exactly what you asked, changing only the wrapper, not the functions or the function calls) is simply to alter the line
func(args)
to read
func(*args)
This tells Python to take the list given (in this case, args
) and pass its contents to the function as positional arguments.
This trick works on both "sides" of the function call, so a function defined like this:
def func2(*args):
return sum(args)
would be able to accept as many positional arguments as you throw at it, and place them all into a list called args
.
I hope this helps to clarify things a little. Note that this is all possible with dicts/keyword arguments as well, using **
instead of *
.
If you work in MVC 4, you can watch this solution, it worked for me.
Add the following Application_Error method to my Global.asax
:
protected void Application_Error(object sender, EventArgs e)
{
Exception exception = Server.GetLastError();
Server.ClearError();
RouteData routeData = new RouteData();
routeData.Values.Add("controller", "Error");
routeData.Values.Add("action", "Index");
routeData.Values.Add("exception", exception);
if (exception.GetType() == typeof(HttpException))
{
routeData.Values.Add("statusCode", ((HttpException)exception).GetHttpCode());
}
else
{
routeData.Values.Add("statusCode", 500);
}
IController controller = new ErrorController();
controller.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
Response.End();
The controller itself is really simple:
public class ErrorController : Controller
{
public ActionResult Index(int statusCode, Exception exception)
{
Response.StatusCode = statusCode;
return View();
}
}
Check the full source code of Mvc4CustomErrorPage at GitHub.
Here's a very good very simple solution on MSDN:
<TextBox
MouseDoubleClick="SelectAddress"
GotKeyboardFocus="SelectAddress"
PreviewMouseLeftButtonDown="SelectivelyIgnoreMouseButton" />
Here's the code behind:
private void SelectAddress(object sender, RoutedEventArgs e)
{
TextBox tb = (sender as TextBox);
if (tb != null)
{
tb.SelectAll();
}
}
private void SelectivelyIgnoreMouseButton(object sender,
MouseButtonEventArgs e)
{
TextBox tb = (sender as TextBox);
if (tb != null)
{
if (!tb.IsKeyboardFocusWithin)
{
e.Handled = true;
tb.Focus();
}
}
}
You can do it like this:
string tmp = "Hello 'World'";
tmp.replace("'", "");
But that will just replace single quotes. To replace double quotes, you must first escape them, like so:
string tmp = "Hello, \"World\"";
tmp.replace("\"", "");
You can replace it with a space, or just leave it empty (I believe you wanted it to be left blank, but your question title implies otherwise.
gawk can get the matching part of every line using this as action:
{ if (match($0,/your regexp/,m)) print m[0] }
match(string, regexp [, array]) If array is present, it is cleared, and then the zeroth element of array is set to the entire portion of string matched by regexp. If regexp contains parentheses, the integer-indexed elements of array are set to contain the portion of string matching the corresponding parenthesized subexpression. http://www.gnu.org/software/gawk/manual/gawk.html#String-Functions
You should add that you have to add an extra ' to escape an exising ' in SQL Server:
smith's -> smith''s
No there isn't. Instead use a while
loop such as:
while 1:
...statements...
if cond:
break
for others there are a solution for any API level , you can place a item on top of each other example :
<?xml version="1.0" encoding="utf-8"?>

<!-- my firt item with 4 corners radius(8dp)
-->
<item>
<shape>
<solid
android:angle="270.0"
android:color="#3D689A" />
<corners android:topLeftRadius="8dp" />
</shape>
</item>
<!-- my second item is on top right for a fake corner radius(0dp)
-->
<item
android:bottom="30dp"
android:left="50dp">
<shape>
<solid android:color="#5C83AF" />
</shape>
</item>
<!-- my third item is on bottom left for a fake corner radius(0dp)
-->
<item
android:right="50dp"
android:top="30dp">
<shape>
<solid android:color="#5C83AF" />
</shape>
</item>
</layer-list>
the result with light color to show you the three items :

Try this way, almost same.. but that's what I did, and working.
<configuration>

<error statusCode="404" redirect="404.aspx" />
<error statusCode="500" redirect="500.aspx" />

or try to change the 404 error page from IIS settings, if required urgently.
This the simplest way to assign an async
arrow function expression to a named variable:
const foo = async () => {
// do something
}
(Note that this is not strictly equivalent to async function foo() { }
. Besides the differences between the function
keyword and an arrow expression, the function in this answer is not "hoisted to the top".)
/^0|[1-9]\d*$/
The question:
Does one unknown equal another unknown?
(NULL = NULL)
That question is something no one can answer so it defaults to true or false depending on your ansi_nulls setting.
However the question:
Is this unknown variable unknown?
This question is quite different and can be answered with true.
nullVariable = null is comparing the values
nullVariable is null is comparing the state of the variable
try this:
if($('input').attr('readonly') == undefined){
alert("foo");
}
if it is not there it will be undefined

What does res.render do and what does the html file look like?
res.render()
function compiles your template (please don't use ejs), inserts locals there, and creates html output out of those two things.
Answering Edit 2 part.
// here you set that all templates are located in `/views` directory
app.set('views', __dirname + '/views');
// here you set that you're using `ejs` template engine, and the
// default extension is `ejs`
app.set('view engine', 'ejs');
// here you render `orders` template
response.render("orders", {orders: orders_json});
So, the template path is views/
(first part) + orders
(second part) + .ejs
(third part) === views/orders.ejs
Anyway, express.js documentation is good for what it does. It is API reference, not a "how to use node.js" book.
I use the following Interactivity Behavior to provide an unloading event to WPF UserControls. You can include the behavior in the UserControls XAML. So you can have the functionality without placing the logic it in every single UserControl.
XAML declaration:
xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
<i:Interaction.Behaviors>
<behaviors:UserControlSupportsUnloadingEventBehavior UserControlClosing="UserControlClosingHandler" />
</i:Interaction.Behaviors>
CodeBehind handler:
private void UserControlClosingHandler(object sender, EventArgs e)
{
// to unloading stuff here
}
Behavior Code:
/// <summary>
/// This behavior raises an event when the containing window of a <see cref="UserControl"/> is closing.
/// </summary>
public class UserControlSupportsUnloadingEventBehavior : System.Windows.Interactivity.Behavior<UserControl>
{
protected override void OnAttached()
{
AssociatedObject.Loaded += UserControlLoadedHandler;
}
protected override void OnDetaching()
{
AssociatedObject.Loaded -= UserControlLoadedHandler;
var window = Window.GetWindow(AssociatedObject);
if (window != null)
window.Closing -= WindowClosingHandler;
}
/// <summary>
/// Registers to the containing windows Closing event when the UserControl is loaded.
/// </summary>
private void UserControlLoadedHandler(object sender, RoutedEventArgs e)
{
var window = Window.GetWindow(AssociatedObject);
if (window == null)
throw new Exception(
"The UserControl {0} is not contained within a Window. The UserControlSupportsUnloadingEventBehavior cannot be used."
.FormatWith(AssociatedObject.GetType().Name));
window.Closing += WindowClosingHandler;
}
/// <summary>
/// The containing window is closing, raise the UserControlClosing event.
/// </summary>
private void WindowClosingHandler(object sender, CancelEventArgs e)
{
OnUserControlClosing();
}
/// <summary>
/// This event will be raised when the containing window of the associated <see cref="UserControl"/> is closing.
/// </summary>
public event EventHandler UserControlClosing;
protected virtual void OnUserControlClosing()
{
var handler = UserControlClosing;
if (handler != null)
handler(this, EventArgs.Empty);
}
}
if you need to select multiple columns from dataframe use 2 pairs of square brackets eg.
df[["product_id","customer_id","store_id"]]
Following is another way of doing it using plain PHP without the information_schema database:
$chkcol = mysql_query("SELECT * FROM `my_table_name` LIMIT 1");
$mycol = mysql_fetch_array($chkcol);
if(!isset($mycol['my_new_column']))
mysql_query("ALTER TABLE `my_table_name` ADD `my_new_column` BOOL NOT NULL DEFAULT '0'");
This is for swift 2.3 Version. You can get the width of string.
var sizeOfString = CGSize()
if let font = UIFont(name: "Helvetica", size: 14.0)
{
let finalDate = "Your Text Here"
let fontAttributes = [NSFontAttributeName: font] // it says name, but a UIFont works
sizeOfString = (finalDate as NSString).sizeWithAttributes(fontAttributes)
}
As per the maven's documentation, there are two possible settings.xml locations
One is the global maven's repo (Your initial download and subsequent unzipped files from apache maven) $M2_HOME/conf/settings.xml
And the second is the user created one (Your local copy) ${user.home}/.m2/settings.xml
The local copy takes precedence over the global copy in terms of settings information. But it is said that they both get merged during "runtime". If you need to have your local copy of the settings.xml, simply copy from the global copy and paste in your .m2 folder and adjust the details as needed
In my case, I installed Android studio, and have some apps (rust lang) that changes the ~/.profile
, and adding adb
to ~/.bash_profile
made the rust un-executable, so I made the changes to the ~/.profile

$ source ~/.profile
$ adb --version

If you are using Oracle 10g, you can use the DECODE
function to pivot the rows into columns:
CREATE TABLE doc_tab (
loan_number VARCHAR2(20),
document_type VARCHAR2(20),
document_id VARCHAR2(20)
);
INSERT INTO doc_tab VALUES('992452533663', 'Voters ID', 'XPD0355636');
INSERT INTO doc_tab VALUES('992452533663', 'Pan card', 'CHXPS5522D');
INSERT INTO doc_tab VALUES('992452533663', 'Drivers licence', 'DL-0420110141769');
COMMIT;
SELECT
loan_number,
MAX(DECODE(document_type, 'Voters ID', document_id)) AS voters_id,
MAX(DECODE(document_type, 'Pan card', document_id)) AS pan_card,
MAX(DECODE(document_type, 'Drivers licence', document_id)) AS drivers_licence
FROM
doc_tab
GROUP BY loan_number
ORDER BY loan_number;
Output:
LOAN_NUMBER VOTERS_ID PAN_CARD DRIVERS_LICENCE ------------- -------------------- -------------------- -------------------- 992452533663 XPD0355636 CHXPS5522D DL-0420110141769
You can achieve the same using Oracle PIVOT
clause, introduced in 11g:
SELECT *
FROM doc_tab
PIVOT (
MAX(document_id) FOR document_type IN ('Voters ID','Pan card','Drivers licence')
);

An addition to the answer: when you do not want to list the folders, only the files in the subfolders, use /A-D switch like this:

http://www.connectionstrings.com is a site where you can find a lot of connection strings. All that you need to do is copy-paste and modify it to suit your needs. It is sure to have all the connection strings for all of your needs.
The color for your buttons comes from the btn-x classes (e.g., btn-primary, btn-success), so if you want to manually change the colors by writing your own custom css rules, you'll need to change:
/*This is modifying the btn-primary colors but you could create your own .btn-something class as well*/
.btn-primary {
color: #fff;
background-color: #0495c9;
border-color: #357ebd; /*set the color you want here*/
}
.btn-primary:hover, .btn-primary:focus, .btn-primary:active, .btn-primary.active, .open>.dropdown-toggle.btn-primary {
color: #fff;
background-color: #00b3db;
border-color: #285e8e; /*set the color you want here*/

Add PresentationCore.dll

As of the time of this writing, Swift natively supports comparing Dates with all comparison operators (i.e. <
, <=
, ==
, >=
, and >
). You can also compare optional Dates but are limited to <
, ==
, and >
. If you need to compare two optional dates using <=
or >=
, i.e.
let date1: Date? = ...
let date2: Date? = ...
if date1 >= date2 { ... }
You can overload the <=
and >=
operators to support optionals:
func <= <T: Comparable>(lhs: T?, rhs: T?) -> Bool {
return lhs == rhs || lhs < rhs
}
func >= <T: Comparable>(lhs: T?, rhs: T?) -> Bool {
return lhs == rhs || lhs > rhs
}

you can use Dependency Walker to view the function name. you can see the function's parameters only if it's decorated. read the following from the FAQ:
How do I view the parameter and return types of a function? For most functions, this information is simply not present in the module. The Windows' module file format only provides a single text string to identify each function. There is no structured way to list the number of parameters, the parameter types, or the return type. However, some languages do something called function "decoration" or "mangling", which is the process of encoding information into the text string. For example, a function like int Foo(int, int) encoded with simple decoration might be exported as _Foo@8. The 8 refers to the number of bytes used by the parameters. If C++ decoration is used, the function would be exported as ?Foo@@YGHHH@Z, which can be directly decoded back to the function's original prototype: int Foo(int, int). Dependency Walker supports C++ undecoration by using the Undecorate C++ Functions Command.
If $AccountNumber
or $Balance
is a node-set, then this behavior could easily happen. It's not because and
is being treated as or
.
For example, if $AccountNumber
referred to nodes with the values 12345
and 66
and $Balance
referred to nodes with the values 55
and 0
, then
$AccountNumber != '12345'
would be true (because 66
is not equal to 12345
) and $Balance != '0'
would be true (because 55
is not equal to 0
).
I'd suggest trying this instead:
<xsl:when test="not($AccountNumber = '12345' or $Balance = '0')">
$AccountNumber = '12345' or $Balance = '0'
will be true any time there is an $AccountNumber
with the value 12345
or there is a $Balance
with the value 0
, and if you apply not()
to that, you will get a false result.

Iterate over the array and do whatever you want with the individual values.
foreach ($array as $key => $value) {

I've used this trick to center an absolutely positioned element. Though, you have to know the element's width.
.divtagABS {
width: 100px;
position: absolute;
left: 50%;
margin-left: -50px;
}
Basically, you use left: 50%, then back it out half of it's width with a negative margin.
This happens when you do not include a message when you try to commit using:
git commit
It launches an editor environment. Quit it by typing :q!
and hitting enter.
It's going to take you back to the terminal without committing, so make sure to try again, this time pass in a message:
git commit -m 'Initial commit'
} means move cursor to next paragraph. so, use v}
to select entire paragraph.
Calling a Sub Procedure – 3 Way technique
Once you have a procedure, whether you created it or it is part of the Visual Basic language, you can use it. Using a procedure is also referred to as calling it.
Before calling a procedure, you should first locate the section of code in which you want to use it. To call a simple procedure, type its name. Here is an example:
Sub CreateCustomer()
Dim strFullName As String
strFullName = "Paul Bertrand Yamaguchi"
msgbox strFullName
End Sub
Sub Exercise()
CreateCustomer
End Sub
Besides using the name of a procedure to call it, you can also precede it with the Call keyword. Here is an example:
Sub CreateCustomer()
Dim strFullName As String
strFullName = "Paul Bertrand Yamaguchi"
End Sub
Sub Exercise()
Call CreateCustomer
End Sub
When calling a procedure, without or without the Call keyword, you can optionally type an opening and a closing parentheses on the right side of its name. Here is an example:
Sub CreateCustomer()
Dim strFullName As String
strFullName = "Paul Bertrand Yamaguchi"
End Sub
Sub Exercise()
CreateCustomer()
End Sub
Procedures and Access Levels
Like a variable access, the access to a procedure can be controlled by an access level. A procedure can be made private or public. To specify the access level of a procedure, precede it with the Private or the Public keyword. Here is an example:
Private Sub CreateCustomer()
Dim strFullName As String
strFullName = "Paul Bertrand Yamaguchi"
End Sub
The rules that were applied to global variables are the same:
Private: If a procedure is made private, it can be called by other procedures of the same module. Procedures of outside modules cannot access such a procedure.
Also, when a procedure is private, its name does not appear in the Macros dialog box
Public: A procedure created as public can be called by procedures of the same module and by procedures of other modules.
Also, if a procedure was created as public, when you access the Macros dialog box, its name appears and you can run it from there
The variable in the for loop is an integer sequence, and so eventually you do this:
> y=as.integer(60000)*as.integer(60000)
Warning message:
In as.integer(60000) * as.integer(60000) : NAs produced by integer overflow
whereas in the while loop you are creating a floating point number.
Its also the reason these things are different:
> seq(0,2,1)
[1] 0 1 2
> seq(0,2)
[1] 0 1 2
Don't believe me?
> identical(seq(0,2),seq(0,2,1))
[1] FALSE
because:
> is.integer(seq(0,2))
[1] TRUE
> is.integer(seq(0,2,1))
[1] FALSE

Another option is
if (myString?.trim()) {
...
}
in C# there is no Java like hidden override, without keyword override on overriding method! see these C# implementations:
variant 1 without override: result is 200
class Car {
public int topSpeed() {
return 200;
}
}
class Ferrari : Car {
public int topSpeed(){
return 400;
}
}
static void Main(string[] args){
Car car = new Ferrari();
int num= car.topSpeed();
Console.WriteLine("Top speed for this car is: "+num);
Console.ReadLine();
}
variant 2 with override keyword: result is 400
class Car {
public virtual int topSpeed() {
return 200;
}
}
class Ferrari : Car {
public override int topSpeed(){
return 400;
}
}
static void Main(string[] args){
Car car = new Ferrari();
int num= car.topSpeed();
Console.WriteLine("Top speed for this car is: "+num);
Console.ReadLine();
}
keyword virtual on Car class is opposite for final on Java, means not final, you can override, or implement if Car was abstract
Organizing your application using class make it easy to you and others who work with you to debug problems and improve the app easily.
You can easily organize your application like this:
class hello(Tk):
def __init__(self):
super(hello, self).__init__()
self.btn = Button(text = "Click me", command=close)
self.btn.pack()
def close():
self.destroy()
app = hello()
app.mainloop()
It depends.
Start with Basic I/O, take a look at Properties, take a look at Preferences API and maybe even Java API for XML Processing and Java Architecture for XML Binding
And if none of those meet your particular needs, you could even look at using some kind of Database
As others have posted: rails server -e production
Or, my personal fave: RAILS_ENV=production
rails s
If you're stuck with SQL Server <2017, you can use GroupConcat. The syntax and the performance is far better than the FOR XML PATH sollution.

GroupConcat does not support ordering, though. You could use PIVOT, CTE's and windows functions if you need ordering:
drop table if exists #students;
create table #students (
name varchar(20),
institution varchar(20),
year int -- order by year
)
go
insert into #students(name, institution, year)
values
('Simon', 'INSTITUTION1', 2005),
('Simon', 'INSTITUTION2', 2008);
with cte as (
select name,
institution,
rn = row_number() over (partition by name order by year)
from #students
)

I tried the standard library's calendar.timegm and it works quite well:
# convert a datetime to milliseconds since Epoch
def datetime_to_utc_milliseconds(aDateTime):
return int(calendar.timegm(aDateTime.timetuple())*1000)
Ref: https://docs.python.org/2/library/calendar.html#calendar.timegm
This is working for me:
$user_info = DB::table('usermetas')
->select('browser', DB::raw('count(*) as total'))
->groupBy('browser')
->get();
List<EmailParameterClass> parameterList = new List<EmailParameterClass>{param1, param2, param3...};
parameterList = parameterList.Where(param => param != null).ToList();
I wrote telegram bot, and have some problem with update rows. Use this example, if you have Model
def update_state(chat_id, state):
try:
value = Users.query.filter(Users.chat_id == str(chat_id)).first()
value.state = str(state)
db.session.flush()
db.session.commit()
#db.session.close()
except:
print('Error in def update_state')
Why use db.session.flush()
? That's why >>> SQLAlchemy: What's the difference between flush() and commit()?
If you are using Asp.Identity UseManager, it automatically sets the value of
RequestContext.Principal.Identity.GetUserId()
based on IdentityUser you use in creating the IdentityDbContext.
If ever you are implementing a custom user table and owin token bearer authentication, kindly check on my answer.
How to get user context during Web Api calls?
Hope it still helps. :)
You just need to write the first query as a subquery (derived table), inside parentheses, pick an alias for it (t
below) and alias the columns as well.
The DISTINCT
can also be safely removed as the internal GROUP BY
makes it redundant:
SELECT DATE(`date`) AS `date` , COUNT(`player_name`) AS `player_count`
FROM (
SELECT MIN(`date`) AS `date`, `player_name`
FROM `player_playtime`
GROUP BY `player_name`
) AS t
GROUP BY DATE( `date`) DESC LIMIT 60 ;
Since the COUNT
is now obvious that is only counting rows of the derived table, you can replace it with COUNT(*)
and further simplify the query:
SELECT t.date , COUNT(*) AS player_count
FROM (
SELECT DATE(MIN(`date`)) AS date
FROM player_playtime
GROUP BY player_name
) AS t
GROUP BY t.date DESC LIMIT 60 ;
Since 1.25.4, docker-compose supports the option --env-file
that enables you to specify a file containing variables.
Yours should look like this:
hostname=my-host-name
And the command:
docker-compose --env-file /path/to/my-env-file config
You can use replace()
For example:
> x <- c(-1,0,1,0,NA,0,1,1)
> x1 <- replace(x,5,1)
> x1
[1] -1 0 1 0 1 0 1 1
> x1 <- replace(x,5,mean(x,na.rm=T))
> x1
[1] -1.00 0.00 1.00 0.00 0.29 0.00 1.00 1.00
In one Line : From [12,0,1,78,12] to 12 0 1 78 12
String srt= list.toString().replaceAll("\\[|\\]|,","");
Here is my solution:
dependencies: Gmaps.js, jQuery
var Maps = function($) {
var lost_addresses = [],
geocode_count = 0;
var addMarker = function() { console.log('Marker Added!') };
return {
getGecodeFor: function(addresses) {
var latlng;
lost_addresses = [];
for(i=0;i<addresses.length;i++) {
GMaps.geocode({
address: addresses[i],
callback: function(response, status) {
if(status == google.maps.GeocoderStatus.OK) {
addMarker();
} else if(status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
lost_addresses.push(addresses[i]);
}
geocode_count++;
// notify listeners when the geocode is done
if(geocode_count == addresses.length) {
$.event.trigger({ type: 'done:geocoder' });
}
}
});
}
},
processLostAddresses: function() {
if(lost_addresses.length > 0) {
this.getGeocodeFor(lost_addresses);
}
}
};
}(jQuery);
Maps.getGeocodeFor(address);
// listen to done:geocode event and process the lost addresses after 1.5s
$(document).on('done:geocode', function() {
setTimeout(function() {
Maps.processLostAddresses();
}, 1500);
});
Here an example that I used in my TubeCount app.
I also use the fields parameter to filter the JSON result, so only the fields that I need are returned.
var fields = "fields=openSearch:totalResults,entry(title,media:group(yt:videoid),media:group(yt:duration),media:group(media:description),media:group(media:thumbnail[@yt:name='default'](@url)),yt:statistics,yt:rating,published,gd:comments(gd:feedLink(@countHint)))";
var channel = "wiibart";
$.ajax({
url: "http://gdata.youtube.com/feeds/api/users/"+channel+"/uploads?"+fields+"&v=2&alt=json",
success: function(data){
var len = data.feed.entry.length;
for(var k =0; k<len; k++){
var yt = data.feed.entry[k];
v.count = Number(yt.yt$statistics != undefined && yt.yt$statistics.viewCount != undefined ? yt.yt$statistics.viewCount : 0);
}
}
});
You could also supply variables on the command line with -PmavenUser=user -PmavenPassword=password
.
This might be useful you can't use a gradle.properties file for some reason. E.g. on a build server we're using Gradle with the -g
option so that each build plan has it's own GRADLE_HOME
.
You might also be interested in go-libucl, a set of Go bindings for UCL, the Universal Configuration Language. UCL is a bit like JSON, but with better support for humans: it supports comments and human-readable constructs like SI multipliers (10k, 40M, etc.) and has a little bit less boilerplate (e.g., quotes around keys). It's actually pretty close to the nginx configuration file format, if you're already familiar with that.
