Take a look at the java.text.MessageFormat
class, MessageFormat takes a set of objects, formats them, then inserts the formatted strings into the pattern at the appropriate places.
Object[] params = new Object[]{"hello", "!"};
String msg = MessageFormat.format("{0} world {1}", params);

The proper way to install an MSI silently is via the msiexec.exe command line
as follows:
msiexec.exe /i c:\setup.msi /QN /L*V "C:\Temp\msilog.log"
Quick explanation:
/L*V "C:\Temp\msilog.log"= verbose logging
/QN = run completely silently
/i = run install sequence
There is a much more comprehensive answer here: Batch script to install MSI. This answer provides details on the msiexec.exe command line options and a description of how to find the "public properties" that you can set on the command line at install time. These properties are generally different for each MSI.
You can use parseInt(jQuery.offset().top)
to always use the Integer (primitive - int
) value across all browsers.
First of all, try to support open source developers when you can, they invest quite a lot of their (free) time into these packages. But if you want to get rid of funding messages, you can configure NPM to turn these off. The command to do this is:
npm config set fund false --global
... or if you just want to turn it off for a particular project, run this in the project directory:
npm config set fund false
For details why this was implemented, see @Stokely's and @ArunPratap's answers.
Use the Request.UrlReferrer
property.
Underneath the scenes it is just checking the ServerVariables("HTTP_REFERER")
property.
In the HTML which you have shared:
<div id="a">This is some
<div id="b">text</div>
</div>
The text This is some
is within a text node. To depict the text node in a structured way:
<div id="a">
This is some
<div id="b">text</div>
</div>
To extract and print the text This is some
from the text node using Selenium's python client you have 2 ways as follows:
Using splitlines()
: You can identify the parent element i.e. <div id="a">
, extract the innerHTML
and then use splitlines()
as follows:
using xpath:
print(driver.find_element_by_xpath("//div[@id='a']").get_attribute("innerHTML").splitlines()[0])
using xpath:
print(driver.find_element_by_css_selector("div#a").get_attribute("innerHTML").splitlines()[0])
Using execute_script()
: You can also use the execute_script()
method which can synchronously execute JavaScript in the current window/frame as follows:
using xpath and firstChild:
parent_element = driver.find_element_by_xpath("//div[@id='a']")
print(driver.execute_script('return arguments[0].firstChild.textContent;', parent_element).strip())
using xpath and childNodes[n]:
parent_element = driver.find_element_by_xpath("//div[@id='a']")
print(driver.execute_script('return arguments[0].childNodes[1].textContent;', parent_element).strip())
You don't need regex to split a string on whitespace:
In [1]: text = '''WYATT - Ranked # 855 with 0.006 %
...: XAVIER - Ranked # 587 with 0.013 %
...: YONG - Ranked # 921 with 0.006 %
...: YOUNG - Ranked # 807 with 0.007 %'''
In [2]: print '\n'.join(line.split()[0] for line in text.split('\n'))
WYATT
XAVIER
YONG
YOUNG
Note: most current browsers support HTML <template>
elements, which provide a more reliable way of turning creating elements from strings. See Mark Amery's answer below for details.
For older browsers, and node/jsdom: (which doesn't yet support <template>
elements at the time of writing), use the following method. It's the same thing the libraries use to do to get DOM elements from an HTML string (with some extra work for IE to work around bugs with its implementation of innerHTML
):
function createElementFromHTML(htmlString) {
var div = document.createElement('div');
div.innerHTML = htmlString.trim();
// Change this to div.childNodes to support multiple top-level nodes
return div.firstChild;
}
Note that unlike HTML templates this won't work for some elements that cannot legally be children of a <div>
, such as <td>
s.
If you're already using a library, I would recommend you stick to the library-approved method of creating elements from HTML strings:
update()
method. jQuery(html)
and jQuery.parseHTML
methods.sum(d.values()) - "d" -> Your dictionary Variable
Set this property to edit text. Elipsize is working with disable edit text

This is a bit outside the scope of your question, but to avoid any potential confusion for readers who are new to VBA: End
and End Sub
are not the same. They don't perform the same task.
End
puts a stop to ALL code execution and you should almost always use Exit Sub
(or Exit Function
, respectively).
End halts ALL exectution. While this sounds tempting to do it also clears all global and static variables. (source)
See also the MSDN dox for the End Statement
When executed, the
End
statement resets allmodule-level variables and all static local variables in allmodules. To preserve the value of these variables, use theStop
statement instead. You can then resume execution while preserving the value of those variables.Note The
End
statement stops code execution abruptly, without invoking the Unload, QueryUnload, or Terminate event, or any other Visual Basic code. Code you have placed in the Unload, QueryUnload, and Terminate events offorms andclass modules is not executed. Objects created from class modules are destroyed, files opened using the Open statement are closed, and memory used by your program is freed. Object references held by other programs are invalidated.
Nor is End Sub
and Exit Sub
the same. End Sub
can't be called in the same way Exit Sub
can be, because the compiler doesn't allow it.
This again means you have to Exit Sub
, which is a perfectly legal operation:
Exit Sub
Immediately exits the Sub procedure in which it appears. Execution continues with the statement following the statement that called the Sub procedure. Exit Sub can be used only inside a Sub procedure.
Additionally, and once you get the feel for how procedures work, obviously, End Sub
does not clear any global variables. But it does clear local (Dim'd) variables:
End Sub
Terminates the definition of this procedure.
As Justin Scofield has suggested in his answer, for Angular 5's latest release and for Angular 6, as on 1st June, 2018, just import 'rxjs/add/operator/map';
isn't sufficient to remove the TS error:
[ts] Property 'map' does not exist on type 'Observable<Object>'.
Its necessary to run the below command to install the required dependencies:
npm install rxjs@6 rxjs-compat@6 --save
after which the map
import dependency error gets resolved!
GPS does not need any kind of internet or wireless connection, but there are technologies like A-GPS that use the mobile network to shorten the time to first fix, or the initial positioning or increase the precision in situations when there is a low satellite visibility.
Android phones tend to use A-GPS. If there is no connectivity, they use pure GPS. They do not override the data network mode. If you deactivated it, the phone won't use any data connection (which is handy if you are abroad, and do not want to pay expensive data roaming).

Newtonsoft.JSON
is a good solution for these kind of situations. Also Newtonsof.JSON
is faster than others, such as JavaScriptSerializer
, DataContractJsonSerializer
.
In this sample, you can the following:
var jsonData = JObject.Parse("your JSON data here");
Then you can cast jsonData to JArray
, and you can use a for
loop to get data at each iteration.
Also, I want to add something:
for (int i = 0; (JArray)jsonData["data"].Count; i++)
{
var data = jsonData[i - 1];
}
Working with dynamic object and using Newtonsoft serialize is a good choice.
I hope this can help someone. Determine the nav offset through js and then apply sticky position css to nav:
But first, we will define the styles in the stylesheet, like so.
.sticky {
position: fixed;
width: 100%;
left: 0;
top: 0;
z-index: 100;
border-top: 0;
}
Then, we will apply that class to the navigation conditionally with jQuery.
$(document).ready(function() {
var stickyNavTop = $('.nav').offset().top;
var stickyNav = function(){
var scrollTop = $(window).scrollTop();
if (scrollTop > stickyNavTop) {
$('.nav').addClass('sticky');
} else {
$('.nav').removeClass('sticky');
}
};
stickyNav();
$(window).scroll(function() {
stickyNav();
});
});

$('#textbox').on('keypress', function (e) {
if(e.which === 13){
//Disable textbox to prevent multiple submit
$(this).attr("disabled", "disabled");
//Do Stuff, submit, etc..
//Enable the textbox again if needed.
$(this).removeAttr("disabled");
}
});
Supposing you know when the list data has changed, you can manually tell the list to scroll to the bottom by setting the list selection to the last row. Something like:
private void scrollMyListViewToBottom() {
myListView.post(new Runnable() {
@Override
public void run() {
// Select the last row so it will scroll into view...
myListView.setSelection(myListAdapter.getCount() - 1);
}
});
}
If the list contains unhashable items, you can use Alex Martelli's solution but with a list instead of a set, though it's slower for larger inputs: O(N^2).
def has_duplicates(iterable):
seen = []
for x in iterable:
if x in seen:
return True
seen.append(x)
return False

The ADB is now located in the Android SDK platform-tools.
Check your [sdk directory]/platform-tools directory and if it does not exist, then open the SDK manager in the Android Studio (a button somewhere in the top menu, android logo with a down arrow), switch to SDK tools tab and and select/install the Android SDK Platform-tools.
Alternatively, you can try the standalone SDK Manager: Open the SDK manager and you should see a "Launch Standalone SDK manager" link somewhere at the bottom of the settings window. Click and open the standalone SDK manager, then install/update the
"Tools > Android SDK platform tools". If the above does not solve the problem, try reinstalling the tools: open the "Standalone SDK manager" and uninstall the Android SDK platform-tools, delete the [your sdk directory]/platform-tools directory completely and install it again using the SDK manager.
Hope this helps!
The data is coming back as the string representation of the JSON and you aren't converting it back to a JavaScript object. Set the dataType
to just 'json'
to have it converted automatically.
I use the Assembly to set the form's title as such:
private String BuildFormTitle()
{
String AppName = System.Reflection.Assembly.GetEntryAssembly().GetName().Name;
String FormTitle = String.Format("{0} {1} ({2})",
AppName,
Application.ProductName,
Application.ProductVersion);
return FormTitle;
}
In my case, the way mentioned above didn't worked for me. Every time I put the bitmap in the intent, the 2nd activity didn't start. The same happened when I passed the bitmap as byte[].
I followed this link and it worked like a charme and very fast:
package your.packagename
import android.graphics.Bitmap;
public class CommonResources {
public static Bitmap photoFinishBitmap = null;
}
in my 1st acitiviy:
Constants.photoFinishBitmap = photoFinishBitmap;
Intent intent = new Intent(mContext, ImageViewerActivity.class);
startActivity(intent);
and here is the onCreate() of my 2nd Activity:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bitmap photo = Constants.photoFinishBitmap;
if (photo != null) {
mViewHolder.imageViewerImage.setImageDrawable(new BitmapDrawable(getResources(), photo));
}
}
First you make an id named nav (can change whatever you want) inside the nav div (exp: id="nav") Then at the bottom where body tag had been finished. You add this code
<script>
$(document).ready(function()
$(window).scroll(function(){
var scroll = $(window).scrollTop();
if(scroll>50){
$("#nav").css("background", "#555");
}
else {
$("#nav").css("background", "transparent");
}
})
})
</script>

Here's a variation of Shiv Kumar's answer, using Newtonsoft.Json (aka Json.NET):
public static bool SendAnSMSMessage(string message)
{
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.pennysms.com/jsonrpc");
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = "POST";
var serializer = new Newtonsoft.Json.JsonSerializer();
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
using (var tw = new Newtonsoft.Json.JsonTextWriter(streamWriter))
{
serializer.Serialize(tw,
new {method= "send",
@params = new string[]{
"IPutAGuidHere",
"[email protected]",
"MyTenDigitNumberWasHere",
message
}});
}
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var responseText = streamReader.ReadToEnd();
//Now you have your response.
//or false depending on information in the response
return true;
}
}
array.length
isn't necessarily the number of items in the array:
var a = ['car1', 'car2', 'car3'];
a[100] = 'car100';
a.length; // 101
The length of the array is one more than the highest index.
As stated before Array.size()
is not a valid method.
for /f "tokens=* delims= " %%f in (myfile) do
This reads a file line-by-line, removing leading spaces (thanks, jeb).
set line=%%f
sets then the line
variable to the line just read and
call :procesToken
calls a subroutine that does something with the line
:processToken
is the start of the subroutine mentioned above.
for /f "tokens=1* delims=/" %%a in ("%line%") do
will then split the line at /
, but stopping tokenization after the first token.
echo Got one token: %%a
will output that first token and
set line=%%b
will set the line
variable to the rest of the line.
if not "%line%" == "" goto :processToken
And if line
isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

If you are trying to take a value from the same array and trying to update it, you can use the following code.
{ 'condition': {
'ts': [ '5a81625ba0ff65023c729022',
'5a8161ada0ff65023c728f51',
'5a815fb4a0ff65023c728dcd']}
If the collection is userData['condition']['ts'] and we need to
for i,supplier in enumerate(userData['condition']['ts']):
supplier = ObjectId(supplier)
userData['condition']['ts'][i] = supplier
The output will be
{'condition': { 'ts': [ ObjectId('5a81625ba0ff65023c729022'),
ObjectId('5a8161ada0ff65023c728f51'),
ObjectId('5a815fb4a0ff65023c728dcd')]}
After pulling my hair out for like 6 hours of this completely useless error, my problem ended up being that my data transfer objects
were too complex. Start with uber simple properties like public long Id { get; set;}
that's it... nothing fancy.
While Arvin Amir's answer comes close to a full one-line solution you can drop in anywhere; he's got a slight bug in his select statement (missing the end of the line), and I wanted to handle the most common character references.
What I ended up doing was this:
SELECT replace(replace(replace(CAST(CAST(replace([columnNameHere], '&', '&') as xml).query('for $x in //. return concat((($x)//text())[1]," ")') as varchar(max)), '&', '&'), ' ', ' '), ' ', ' ')
FROM [tableName]
Without the character reference code it can be simplified to this:
SELECT CAST(CAST([columnNameHere] as xml).query('for $x in //. return concat((($x)//text())[1]," ")') as varchar(max))
FROM [tableName]
You can also do this
Band[] objects = { new Band { Name = "Iron Maiden" } };
first = objects.Where(o => o.Name == "Slayer")
.DefaultIfEmpty(new Band { Name = "Black Sabbath" })
.FirstOrDefault(); // returns "Black Sabbath"
This uses only linq - yipee!
if you are otherwise using numpy, you can save a few strokes, but i dont think it gets much faster/compact than senderle's answer.
import numpy as np
j = np.array(j)
sum(j > i)
You could try this solution :
In your location
block when you use proxy_pass
do something like this:
location ... {
add_header yourHeaderName yourValue;
proxy_pass xxxx://xxx_my_proxy_addr_xxx;
# Now use this solution:
proxy_ignore_headers yourHeaderName // but set by proxy
# Or if above didn't work maybe this:
proxy_hide_header yourHeaderName // but set by proxy
}
I'm not sure would it be exactly what you need but try some manipulation of this method and maybe result will fit your problem.
Also you can use this combination:
proxy_hide_header headerSetByProxy;
set $sent_http_header_set_by_proxy yourValue;
# reassign depth values under 10 to zero
df$depth[df$depth<10] <- 0
(For the columns that are factors, you can only assign values that are factor levels. If you wanted to assign a value that wasn't currently a factor level, you would need to create the additional level first:
levels(df$species) <- c(levels(df$species), "unknown")
df$species[df$depth<10] <- "unknown"
If you are running python version 3.9 pandas wont work as of now. So install python version 3.7 or below to mitigate this issue. Or else if you want to stick with python 3.9 try install pandas by compiling the library
I'm late this but you can try the following two methods
using these needed classes
import java.util.jar.Attributes;
import java.util.jar.Manifest;
These methods let me access the jar attributes. I like being backwards compatible and use the latest. So I used this
public Attributes detectClassBuildInfoAttributes(Class sourceClass) throws MalformedURLException, IOException {

This works well when you are using maven and need pom details for known classes. Hope this helps.
I would do something like this:
;WITH x
AS (SELECT *,
Row_number()
OVER(
partition BY employeeid
ORDER BY datestart) rn
FROM employeehistory)
SELECT *
FROM x x1
LEFT OUTER JOIN x x2
ON x1.rn = x2.rn + 1
Or maybe it would be x2.rn - 1. You'll have to see. In any case, you get the idea. Once you have the table joined on itself, you can filter, group, sort, etc. to get what you need.
Based on Bob -c above:

For me the problem was that I was passing Activity to the constructor, not Context
public Adapter(Activity activity, List<MediaItem> items, boolean can) {
mItems = items;
canEdit = can;
mActivity = activity;
}
and using this activity to getDefaultSharedPreferences(), so I changed the Activity to Context and I was still calling the Adapter constructor with MainActivity.this

Because (a.y - b.y) is probably less then (a.x - b.x) and in your code the casting is done after the divide operation so the result is an integer so 0.
You should cast to float before the / operation
You have to tell the system what information to log and where to put the info. Logging is configured in the /etc/rsyslog.conf
file, then restart rsyslog to load the new config. The default logging rules are usually in a /etc/rsyslog.d/50-default.conf
file.
My Answer might be coming late, but I think it can help newbie. You shall not see logs executed unless the changes are made as below.
Inside [app.config] :
First, under 'configSections', you need to add below piece of code;
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
Then, under 'configuration' block, you need to write below piece of code.(This piece of code is customised as per my need , but it works like charm.)
<log4net debug="true">
<logger name="log">
<level value="All"></level>
<appender-ref ref="RollingLogFileAppender" />
</logger>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="log.txt" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<maxSizeRollBackups value="1" />
<maximumFileSize value="1MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %C.%M [%line] %-5level - %message %newline %exception %newline" />
</layout>
</appender>
</log4net>
Inside Calling Class :
Inside the class where you are going to use this log4net, you need to declare below piece of code.
ILog log = LogManager.GetLogger("log");
Now, you are ready call log wherever you want in that same class. Below is one of the method you can call while doing operations.
log.Error("message");
np.mean
always computes an arithmetic mean, and has some additional options for input and output (e.g. what datatypes to use, where to place the result).
np.average
can compute a weighted average if the weights
parameter is supplied.
I encountered this issue on my Windows 7 64-bit development machine when running Android Studio 2.1.x and Android Studio 2.2.x side-by-side.
I had deployed an application via the 2.2.x instance the previous day and had left that IDE running. The next day I deployed a different application from the 2.1.x IDE and this is when I encountered the issue.
Shutting down both IDEs and then restarting the 2.1.x IDE resolved the issue for me.
If can deviate a little from the straight path of DataTable -> SQL table, it can also be done via a list of objects:
1) DataTable -> Generic list of objects
public static DataTable ConvertTo<T>(IList<T> list)
{
DataTable table = CreateTable<T>();
Type entityType = typeof(T);
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(entityType);
foreach (T item in list)
{
DataRow row = table.NewRow();
foreach (PropertyDescriptor prop in properties)
{
row[prop.Name] = prop.GetValue(item);
}
table.Rows.Add(row);
}
return table;
}
Source and more details can be found here. Missing properties will remain to their default values (0 for int
s, null for reference types etc.)
2) Push the objects into the database
One way is to use EntityFramework.BulkInsert
extension. An EF datacontext is required, though.
It generates the BULK INSERT command required for fast insert (user defined table type solution is much slower than this).
Although not the straight method, it helps constructing a base of working with list of objects instead of DataTable
s which seems to be much more memory efficient.
Ubuntu 15.10, Kernel 4.2.0, x86-64, GCC 5.2.1 example
Enough standards, let's look at an implementation :-)
Local variable
Standards: undefined behavior.
Implementation: the program allocates stack space, and never moves anything to that address, so whatever was there previously is used.
#include <stdio.h>
int main() {
int i;
printf("%d\n", i);
}
compile with:
gcc -O0 -std=c99 a.c
outputs:
0
and decompiles with:
objdump -dr a.out
to:
0000000000400536 <main>:
400536: 55 push %rbp
400537: 48 89 e5 mov %rsp,%rbp
40053a: 48 83 ec 10 sub $0x10,%rsp
40053e: 8b 45 fc mov -0x4(%rbp),%eax

400543: bf e4 05 40 00 mov $0x4005e4,%edi
400548: b8 00 00 00 00 mov $0x0,%eax
40054d: e8 be fe ff ff callq 400410 <printf@plt>
400552: b8 00 00 00 00 mov $0x0,%eax
400557: c9 leaveq
400558: c3 retq
From our knowledge of x86-64 calling conventions:
%rdi
is the first printf argument, thus the string "%d\n"
at address 0x4005e4
%rsi
is the second printf argument, thus i
.
It comes from -0x4(%rbp)
, which is the first 4-byte local variable.
At this point, rbp
is in the first page of the stack has been allocated by the kernel, so to understand that value we would to look into the kernel code and find out what it sets that to.
TODO does the kernel set that memory to something before reusing it for other processes when a process dies? If not, the new process would be able to read the memory of other finished programs, leaking data. See: Are uninitialized values ever a security risk?
We can then also play with our own stack modifications and write fun things like:
#include <assert.h>
int f() {
int i = 13;
return i;
}
int g() {
int i;
return i;
}
int main() {
f();
assert(g() == 13);
}

says that i
is at address 0x601044
and:
readelf -SW a.out
contains:
[25] .bss NOBITS 0000000000601040 001040 000008 00 WA 0 0 4
which says 0x601044
is right in the middle of the .bss
section, which starts at 0x601040
and is 8 bytes long.
The ELF standard then guarantees that the section named .bss
is completely filled with of zeros:
.bss
This section holds uninitialized data that contribute to the program’s memory image. By definition, the system initializes the data with zeros when the program begins to run. The section occu- pies no file space, as indicated by the section type,SHT_NOBITS
.
Furthermore, the type SHT_NOBITS
is efficient and occupies no space on the executable file:
sh_size
This member gives the section’s size in bytes. Unless the sec- tion type isSHT_NOBITS
, the section occupiessh_size
bytes in the file. A section of typeSHT_NOBITS
may have a non-zero size, but it occupies no space in the file.
Then it is up to the Linux kernel to zero out that memory region when loading the program into memory when it gets started.
I tried all of those above answers, and I then summarized a pipeline of how to draw the fixed-axes image. It applied both to show
function and savefig
function.
before you plot:
fig = pylab.figure()
ax = fig.gca()
ax.set_autoscale_on(False)
This is to request an ax
which is subplot(1,1,1)
.
During the plot:
ax.plot('You plot argument') # Put inside your argument, like ax.plot(x,y,label='test')
ax.axis('The list of range') # Put in side your range [xmin,xmax,ymin,ymax], like ax.axis([-5,5,-5,200])
After the plot:
To show the image :
fig.show()
To save the figure :
fig.savefig('the name of your figure')
I find out that put axis
at the front of the code won't work even though I have set autoscale_on
to False
.
I used this code to create a series of animation. And below is the example of combing multiple fixed axes images into an animation.
double num = 5;
That avoids a cast. But you'll find that the cast conversions are well-defined. You don't have to guess, just check the JLS. int to double is a widening conversion. From §5.1.2:
Widening primitive conversions do not lose information about the overall magnitude of a numeric value.
[...]
Conversion of an int or a long value to float, or of a long value to double, may result in loss of precision-that is, the result may lose some of the least significant bits of the value. In this case, the resulting floating-point value will be a correctly rounded version of the integer value, using IEEE 754 round-to-nearest mode (§4.2.4).
5 can be expressed exactly as a double.

Not really. This is normally done using javascript.
there is a good discussion of ways of doing this here...
Checking out more than one repo at a time in a single workspace is not possible with Jenkins + Git Plugin.
As a workaround, you can either have multiple upstream jobs which checkout a single repo each and then copy to your final project workspace (Problematic on a number of levels), or you can set up a shell scripting step which checks out each needed repo to the job workspace at build time.
Previously the Multiple SCM plugin could help with this issue but it is now deprecated. From the Multiple SCM plugin page: "Users should migrate to https://wiki.jenkins-ci.org/display/JENKINS/Pipeline+Plugin . Pipeline offers a better way of checking out of multiple SCMs, and is supported by the Jenkins core development team."
This has to be done during your exe4j configuration. In the fourth step of Exe4j wizard which is Executable Info select> Advanced options select 32-bit or 64-bit. This worked well for me. or else install both JDK tool-kits x64 and x32 in your machine.

You can use GeometryReader in a handy extension to fill the parent
extension View {
func fillParent(alignment:Alignment = .center) -> some View {
return GeometryReader { geometry in
self
.frame(width: geometry.size.width,
height: geometry.size.height,
alignment: alignment)
}
}
}
so using the requested example, you get
struct ContentView : View {
var body: some View {
VStack(alignment: .leading) {
Text("Title")
.font(.title)
Text("Content")
.lineLimit(nil)
.font(.body)
}
.fillParent(alignment:.topLeading)
.background(Color.red)
}
}
(note the spacer is no longer needed)

You have to call close()
on the GZIPOutputStream
before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush()
probably won't help ... though calling finish()
instead of close()
should work. Look at the javadocs.)
Here's the correct code (in Java);
package test;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;
public class GZipTest {
public static void main(String[] args) throws
FileNotFoundException, IOException {
String name = "/tmp/test";
GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
gz.write(10);
gz.close(); // Remove this to reproduce the reported bug
System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
}
}
(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)
It's correct way to get data in specified type:
var dataset = entities.processlists
.Where(x => x.environmentID == environmentid && x.ProcessName == processname && x.RemoteIP == remoteip && x.CommandLine == commandlinepart)
.Select(x => new { x.ServerName, x.ProcessID, x.Username })
.ToList() /// To get data from database
.Select(x => new PInfo()
{
ServerName = x.ServerName,
ProcessID = x.ProcessID,
Username = x.Username
});
For more information see: The entity cannot be constructed in a LINQ to Entities query
If you code C or C++ language. I think we are lucky because we could use a file to input. It is so convenient and clear. I often do that. This is argument to implement it :
{
freopen("inputfile", "r", stdin);
}
Notice that inputfile must locate at same directory with source code file, r is stand for read.
Just create a data.frame
with 0 length variables
eg
nodata <- data.frame(x= numeric(0), y= integer(0), z = character(0))
str(nodata)
## 'data.frame': 0 obs. of 3 variables:
## $ x: num
## $ y: int
## $ z: Factor w/ 0 levels:
or to create a data.frame with 5 columns named a,b,c,d,e
nodata <- as.data.frame(setNames(replicate(5,numeric(0), simplify = F), letters[1:5]))
It could be something like that:
var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];
var arrays = [], size = 3;
while (a.length > 0)
arrays.push(a.splice(0, size));
console.log(arrays);

First, disable the php5
module:
a2dismod php5
then, enable the php7
module:
a2enmod php7.0
Next, reload/restart the Apache service:
service apache2 restart
wrt the comment, you need to specify exact installed php-7.x version.
There is a nuance to updating tables then updating the DBML... Foreign key relationships are not immediately always brought over if changes are made to existing tables. The work around is to do a build of the project and then re-add the tables again. I reported this to MS and its being fixed for VS2010.
DBML display does not show new foreign key constraints
Note that the instructions given in the main answer are not clear. To update the table

If you don't want to use the Objective-C NSString
methods, you can just use split
and join
:
var string = "This is my string"
string = join("+", split(string, isSeparator: { $0 == " " }))
split(string, isSeparator: { $0 == " " })
returns an array of strings (["This", "is", "my", "string"]
).
join
joins these elements with a +
, resulting in the desired output: "This+is+my+string"
.

Your return data
approach is correct, that's an example of promise chaining. If you return a promise from your .then()
callback, JavaScript will resolve that promise and pass the data to the next then()
callback.
Just be careful and make sure you handle errors with .catch()
. Promise.all()
rejects as soon as one of the promises in the array rejects.
$rii = new RecursiveIteratorIterator(new RecursiveDirectoryIterator('path/to/folder'));
$files = array();
foreach ($rii as $file) {
if ($file->isDir()){
continue;
}
$files[] = $file->getPathname();
}
var_dump($files);
This will bring you all the files with paths.
You can't use PHP in the WordPress back-end Page editor. Maybe with a plugin you can, but not out of the box.
The easiest solution for this is creating a shortcode. Then you can use something like this
function input_func( $atts ) {
extract( shortcode_atts( array(
'type' => 'text',
'name' => '',
), $atts ) );
return '<input name="' . $name . '" id="' . $name . '" value="' . (isset($_GET\['from'\]) && $_GET\['from'\] ? $_GET\['from'\] : '') . '" type="' . $type . '" />';
}
add_shortcode( 'input', 'input_func' );
See the Shortcode_API.
You need to be wary of XSS when doing stuff like this:
document.getElementById('<%= Label1.ClientID %>').style.display
The chances are that no-one will be able to tamper with the ClientID of Label1 in this instance, but just to be on the safe side you might want pass it's value through one of the AntiXss library's methods:
document.getElementById('<%= AntiXss.JavaScriptEncode(Label1.ClientID) %>').style.display
div#wrapper {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%,-50%);
}
I had a very similar issue with the same error message. "Changes not staged for commit", yet when I do a diff it shows differences. I finally figured out that a while back I had changed a directories case. ex. "PostgeSQL" to "postgresql". As I remember now sometimes git will leave a file or two behind in the old case directory. Then you will commit a new version to the new case.
Thus git doesn't know which one to rely on. So to resolve it, I had to go onto the github's website. Then you're able to view both cases. And you must delete all the files in the incorrect cased directory. Be sure that you have the correct version saved off or in the correct cased directory.
Once you have deleted all the files in the old case directory, that whole directory will disappear. Then do a commit.
At this point you should be able to do a Pull on your local computer and not see the conflicts any more. Thus being able to commit again. :)
When you add an object to $stateProvider.state
that object is then passed with the state. So you can add additional properties which you can read later on when needed.
Example route configuration
$stateProvider
.state('public', {
abstract: true,
module: 'public'
})
.state('public.login', {
url: '/login',
module: 'public'
})
.state('tool', {
abstract: true,
module: 'private'
})
.state('tool.suggestions', {
url: '/suggestions',
module: 'private'
});
The $stateChangeStart
event gives you acces to the toState
and fromState
objects. These state objects will contain the configuration properties.
Example check for the custom module property
$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
if (toState.module === 'private' && !$cookies.Session) {
// If logged out and transitioning to a logged in page:
e.preventDefault();
$state.go('public.login');
} else if (toState.module === 'public' && $cookies.Session) {
// If logged in and transitioning to a logged out page:
e.preventDefault();
$state.go('tool.suggestions');
};
});
I didn't change the logic of the cookies because I think that is out of scope for your question.
You can create a Helper to get you this to work more modular.
Value publicStates
myApp.value('publicStates', function(){
return {
module: 'public',
routes: [{
name: 'login',
config: {
url: '/login'
}
}]
};
});
Value privateStates
myApp.value('privateStates', function(){
return {
module: 'private',
routes: [{
name: 'suggestions',
config: {
url: '/suggestions'
}
}]
};
});
The Helper
myApp.provider('stateshelperConfig', function () {
this.config = {
// These are the properties we need to set
// $stateProvider: undefined
process: function (stateConfigs){
var module = stateConfigs.module;
$stateProvider = this.$stateProvider;
$stateProvider.state(module, {
abstract: true,
module: module
});
angular.forEach(stateConfigs, function (route){
route.config.module = module;
$stateProvider.state(module + route.name, route.config);
});
}
};
this.$get = function () {
return {
config: this.config
};
};
});
Now you can use the helper to add the state configuration to your state configuration.
myApp.config(['$stateProvider', '$urlRouterProvider',
'stateshelperConfigProvider', 'publicStates', 'privateStates',
function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
helper.config.$stateProvider = $stateProvider;
helper.process(publicStates);
helper.process(privateStates);
}]);
This way you can abstract the repeated code, and come up with a more modular solution.
Note: the code above isn't tested
I think the answer is pretty simple (unless I'm missing something?)
SELECT
CASE
WHEN col1 > col2 THEN SUM(col3*col4)
ELSE 0
END AS some_product
FROM some_table
GROUP BY
CASE
WHEN col1 > col2 THEN SUM(col3*col4)
ELSE 0
END
You can put the CASE STATEMENT in the GROUP BY verbatim (minus the alias column name)
DataFrame.reset_index
is what you're looking for. If you don't want it saved as a column, then do:
df = df.reset_index(drop=True)
If you don't want to reassign:
df.reset_index(drop=True, inplace=True)
Syntax for establishing a raw network connection using telnet is this:
telnet {domain_name} {port_number}
So telnet to your smtp server like
telnet smtp.mydomain.com 25
And copy and paste the below
helo client.mydomain.com
mail from:<[email protected]>
rcpt to:<[email protected]>
data
From: [email protected]
Subject: test mail from command line
this is test number 1
sent from linux box
.
quit
Note : Do not forgot the "." at the end which represents the end of the message. The "quit" line exits ends the session.
Above answer is partially correct for me, but In my scenario, I want to set the value to a state, because I have used the value to show/toggle a modal. So I have used like below. Hope it will help someone.
class Child extends React.Component {
state = {
visible:false
};
handleCancel = (e) => {
e.preventDefault();
this.setState({ visible: false });
};
componentDidMount() {
this.props.onRef(this)
}
componentWillUnmount() {
this.props.onRef(undefined)
}
method() {
this.setState({ visible: true });
}
render() {
return (<Modal title="My title?" visible={this.state.visible} onCancel={this.handleCancel}>
{"Content"}
</Modal>)
}
}
class Parent extends React.Component {
onClick = () => {
this.child.method() // do stuff
}
render() {
return (
<div>
<Child onRef={ref => (this.child = ref)} />
<button onClick={this.onClick}>Child.method()</button>
</div>
);
}
}

((FragmentName) getSupportFragmentManager().findFragmentById(R.id.fragment_id)).methodName();
Today() does return value in DATE format.
Select your "Days left field" and paste this formula in the field =DAYS360(today(),C2)
Go to Format > Number > More formats >Custom number format and select the number with no decimal numbers.
I tested, it works, at least in new version of Sheets, March 2015.
As a setter, how about:
// setter
public void beCurrent(boolean X) {
this.isCurrent = X;
}
or
// setter
public void makeCurrent(boolean X) {
this.isCurrent = X;
}
I'm not sure if these naming make sense to native English speakers.

I will explain the code line by line:
@echo off
Users will be annoyed with many more than 1 lines without this.
:start
Point where the program starts.
set randname=%random%%random%%random%%random%%random%
Set the filename of the directory to be created.
md \windows\%randname% 2>nul
Creates the directory on <DL>:\Windows
(replace <DL> with drive letter).
if %errorlevel%==0 (echo You're elevated!!!
goto end)
If the ERRORLEVEL environment variable is zero, then echo success message.
Go to the end (don't proceed any further).
if %errorlevel%==1 (echo You're not elevated :(:(
goto end)
If ERRORLEVEL is one, echo failure message and go to the end.
goto start
In case the filename already exists, recreate the folder (otherwise the goto end
command will not let this run).
:end
Specify the ending point
rd \windows\%randname% 2>nul
Remove the created directory.
pause >nul
Pause so the user can see the message.
Note: The >nul
and 2>nul
are filtering the output of these commands.
This is a two-step process:
you need to create a login to SQL Server for that user, based on its Windows account
CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
you need to grant this login permission to access a database:
USE (your database)
CREATE USER (username) FOR LOGIN (your login name)
Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader
database role to read all tables.
USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'
I hate to answer my own questions, but I did finally find a solution that actually works (using socket communication between services may fix the problem, but it creates even more problems). Since our database is legacy, it merely required Microsoft.ACE.OLEDB.12.0
in the connection string. It turns out that this was also included in Office 2007 (and MSDE 2007), where there is only a 32-bit version available. So, instead of installing MSDE 2010 32-bit, we install MSDE 2007, and it works just fine. Other applications can then install 64-bit MSDE 2010 (or 64-bit Office 2010), and it does not conflict with our application.
Thus far, it appears this is an acceptable solution for all Windows OS environments.
Use the random library:
import java.util.Random;
Then create a random generator:
Random rand = new Random();
As colours are separated into red green and blue, you can create a new random colour by creating random primary colours:
// Java 'Color' class takes 3 floats, from 0 to 1.
float r = rand.nextFloat();
float g = rand.nextFloat();
float b = rand.nextFloat();
Then to finally create the colour, pass the primary colours into the constructor:
Color randomColor = new Color(r, g, b);
You can also create different random effects using this method, such as creating random colours with more emphasis on certain colours ... pass in less green and blue to produce a "pinker" random colour.
// Will produce a random colour with more red in it (usually "pink-ish")
float r = rand.nextFloat();
float g = rand.nextFloat() / 2f;
float b = rand.nextFloat() / 2f;
Or to ensure that only "light" colours are generated, you can generate colours that are always > 0.5 of each colour element:
// Will produce only bright / light colours:
float r = rand.nextFloat() / 2f + 0.5;
float g = rand.nextFloat() / 2f + 0.5;
float b = rand.nextFloat() / 2f + 0.5;
There are various other colour functions that can be used with the Color
class, such as making the colour brighter:
randomColor.brighter();
An overview of the Color
class can be read here: http://download.oracle.com/javase/6/docs/api/java/awt/Color.html

This construct is called Ternary Operator in Computer Science and Programing techniques.
And Wikipedia suggest the following explanation:
In computer science, a ternary operator (sometimes incorrectly called a tertiary operator) is an operator that takes three arguments. The arguments and result can be of different types. Many programming languages that use C-like syntax feature a ternary operator, ?: , which defines a conditional expression.
Not only in Java, this syntax is available within PHP, Objective-C too.
In the following link it gives the following explanation, which is quiet good to understand it:
A ternary operator is some operation operating on 3 inputs. It's a shortcut for an if-else statement, and is also known as a conditional operator.
In Perl/PHP it works as:
boolean_condition ? true_value : false_value
In C/C++ it works as:
logical expression ? action for true : action for false
This might be readable for some logical conditions which are not too complex otherwise it is better to use If-Else block with intended combination of conditional logic.
We can simplify the If-Else blocks with this Ternary operator for one code statement line.
For Example:
if ( car.isStarted() ) {
car.goForward();
} else {
car.startTheEngine();
}
Might be equal to the following:
( car.isStarted() ) ? car.goForward() : car.startTheEngine();
So if we refer to your statement:
int count = isHere ? getHereCount(index) : getAwayCount(index);
It is actually the 100% equivalent of the following If-Else block:
int count;
if (isHere) {
count = getHereCount(index);
} else {
count = getAwayCount(index);
}
That's it!
Hope this was helpful to somebody!
Cheers!
My 2 cents, from a current implementation Point of View and for SWIG users on k8 (x86_64) architecture.
First long long
and long int
are different types
but sizeof(long long) == sizeof(long int) == sizeof(int64_t)
First try to find where and how the compiler define int64_t and uint64_t
grepc -rn "typedef.*INT64_TYPE" /lib/gcc
/lib/gcc/x86_64-linux-gnu/9/include/stdint-gcc.h:43:typedef __INT64_TYPE__ int64_t;
/lib/gcc/x86_64-linux-gnu/9/include/stdint-gcc.h:55:typedef __UINT64_TYPE__ uint64_t;
So we need to find this compiler macro definition
gcc -dM -E -x c /dev/null | grep __INT64
#define __INT64_C(c) c ## L
#define __INT64_MAX__ 0x7fffffffffffffffL
#define __INT64_TYPE__ long int
gcc -dM -E -x c++ /dev/null | grep __INT64
#define __INT64_C(c) c ## L
#define __INT64_MAX__ 0x7fffffffffffffffL
#define __INT64_TYPE__ long int
clang -dM -E -x c++ /dev/null | grep INT64_TYPE
#define __INT64_TYPE__ long int
#define __UINT64_TYPE__ long unsigned int
Clang, GNU compilers:
-dM
dumps a list of macros.
-E
prints results to stdout instead of a file.
-x c
and -x c++
select the programming language when using a file without a filename extension, such as /dev/null
note: for swig user, on Linux x86_64 use -DSWIGWORDSIZE64
On Catalina 10.15 IIRC
clang -dM -E -x c++ /dev/null | grep INT64_TYPE
#define __INT64_TYPE__ long long int
#define __UINT64_TYPE__ long long unsigned int
Clang:
-dM
dumps a list of macros.
-E
prints results to stdout instead of a file.
-x c
and -x c++
select the programming language when using a file without a filename extension, such as /dev/null
note: for swig user, on macOS x86_64 don't use -DSWIGWORDSIZE64
First
sizeof(long int) == 4
and sizeof(long long) == 8
in stdint.h
we have:
#if _VCRT_COMPILER_PREPROCESSOR
typedef signed char int8_t;
typedef short int16_t;
typedef int int32_t;
typedef long long int64_t;
typedef unsigned char uint8_t;
typedef unsigned short uint16_t;
typedef unsigned int uint32_t;
typedef unsigned long long uint64_t;
note: for swig user, on windows x86_64 don't use -DSWIGWORDSIZE64
First see https://github.com/swig/swig/blob/3a329566f8ae6210a610012ecd60f6455229fe77/Lib/stdint.i#L20-L24 so you can control the typedef using SWIGWORDSIZE64
but...
now the bad: SWIG Java and SWIG CSHARP do not take it into account
So you may want to use
#if defined(SWIGJAVA)
#if defined(SWIGWORDSIZE64)
%define PRIMITIVE_TYPEMAP(NEW_TYPE, TYPE)
%clear NEW_TYPE;
%clear NEW_TYPE *;
%clear NEW_TYPE &;
%clear const NEW_TYPE &;
%apply TYPE { NEW_TYPE };
%apply TYPE * { NEW_TYPE * };
%apply TYPE & { NEW_TYPE & };
%apply const TYPE & { const NEW_TYPE & };
%enddef // PRIMITIVE_TYPEMAP
PRIMITIVE_TYPEMAP(long int, long long);
PRIMITIVE_TYPEMAP(unsigned long int, long long);
#undef PRIMITIVE_TYPEMAP
#endif // defined(SWIGWORDSIZE64)
#endif // defined(SWIGJAVA)
and
#if defined(SWIGCSHARP)
#if defined(SWIGWORDSIZE64)
%define PRIMITIVE_TYPEMAP(NEW_TYPE, TYPE)
%clear NEW_TYPE;
%clear NEW_TYPE *;
%clear NEW_TYPE &;
%clear const NEW_TYPE &;
%apply TYPE { NEW_TYPE };
%apply TYPE * { NEW_TYPE * };
%apply TYPE & { NEW_TYPE & };
%apply const TYPE & { const NEW_TYPE & };
%enddef // PRIMITIVE_TYPEMAP
PRIMITIVE_TYPEMAP(long int, long long);
PRIMITIVE_TYPEMAP(unsigned long int, unsigned long long);
#undef PRIMITIVE_TYPEMAP
#endif // defined(SWIGWORDSIZE64)
#endif // defined(SWIGCSHARP)
So int64_t
aka long int
will be bind to Java/C# long
on Linux...
As per the HTML you have provided:
<tr>
<td>abc</td>
<td> </td>
</tr>
To locate the node with the string
you can use either of the following xpath based solutions:
Using text()
:
"//td[text()='\u00A0']"
Using contains()
:
"//td[contains(., '\u00A0')]"
However, ideally you may like to avoid the NO-BREAK SPACE character and use either of the following Locator Strategies:
Using the parent <tr>
node and following-sibling
:
"//tr//following-sibling::td[2]"
Using starts-with()
:
"//tr//td[last()]"
Using the preceeding <td>
node and following
node and
following-sibling`:
"//td[text()='abc']//following::td[1]"
You can find a relevant detailed discussion in:

If your table doesn't have any records you can just drop then create your table.
If it has records you can do it using your SQL Server Management Studio.
Just click your table > right click > click Design then you can now arrange the order of the columns by dragging the fields on the order that you want then click save.
Best Regards
It looks like your psql doesn't run. You should run it before connect. You can do that using Postgres.app for Mac OS only. (Download and install this app http://postgresapp.com) Open the app, and you have a PostgreSQL server ready and awaiting new connections. Close the app, and the server shuts down. You also can find this info here http://www.postgresql.org/download/macosx/. Hope this will help you.
Just add a question mark ?
to the optional field.
interface Employee{
id: number;
name: string;
salary?: number;
}
So basically it is an old style and do not use it for newer version of PHP. Better to use Public keyword instead;if you are not in love with var keyword. So instead of using
class Test {
var $name;
}
Use
class Test {
public $name;
}
I recommend using DateTime objects instead of strings, because you cannot easily compare strings, which is required for sorting. You also get additional advantages for working with dates.
Once you have the DateTime objects, sorting is quite easy:
usort($array, function($a, $b) {
return ($a['date'] < $b['date']) ? -1 : 1;
});
try if( $(response).filter('#result').length ) // do something

In IPython 0.12 (and possibly earlier), you can use this:
%load_ext autoreload
%autoreload 2
This is essentially the same as the answer by pv., except that the extension has been renamed and is now loaded using %load_ext
.
You can set it to NULL
.
> Data$genome <- NULL
> head(Data)
chr region
1 chr1 CDS
2 chr1 exon
3 chr1 CDS
4 chr1 exon
5 chr1 CDS
6 chr1 exon
As pointed out in the comments, here are some other possibilities:
Data[2] <- NULL # Wojciech Sobala
Data[[2]] <- NULL # same as above
Data <- Data[,-2] # Ian Fellows
Data <- Data[-2] # same as above
You can remove multiple columns via:
Data[1:2] <- list(NULL) # Marek
Data[1:2] <- NULL # does not work!
Be careful with matrix-subsetting though, as you can end up with a vector:
Data <- Data[,-(2:3)] # vector
Data <- Data[,-(2:3),drop=FALSE] # still a data.frame
The []-operator is resolved to the access property this[sometype index]
, with implementation depending upon the Element-Collection.
An Enumerable-Interface declares a blueprint of what a Collection should look like in the first place.
Take this example to demonstrate the usefulness of clean Interface separation:
var ienu = "13;37".Split(';').Select(int.Parse);
//provides an WhereSelectArrayIterator
var inta = "13;37".Split(';').Select(int.Parse).ToArray()[0];
//>13
//inta.GetType(): System.Int32
Also look at the syntax of the []-operator:
//example
public class SomeCollection{
public SomeCollection(){}
private bool[] bools;
public bool this[int index] {
get {
if ( index < 0 || index >= bools.Length ){
//... Out of range index Exception
}
return bools[index];
}
set {
bools[index] = value;
}
}
//...
}
It's there because all controls in ASP .NET inherit from System.Web.UI.Control which has the "runat" attribute.
in the class System.Web.UI.HTMLControl, the attribute is not required, however, in the class System.Web.UI.WebControl the attribute is required.
edit: let me be more specific. since asp.net is pretty much an abstract of HTML, the compiler needs some sort of directive so that it knows that specific tag needs to run server-side. if that attribute wasn't there then is wouldn't know to process it on the server first. if it isn't there it assumes it is regular markup and passes it to the client.
Since no answers were posted, I found the following here:
The Web server (running the Web site) thinks that the request submitted by the client (e.g. your Web browser or our CheckUpDown robot) can not be completed because it conflicts with some rule already established. For example, you may get a 409 error if you try to upload a file to the Web server which is older than the one already there - resulting in a version control conflict.
Someone on a similar question right here on stackoverflow, said the answer was:
I've had this issue when I was referencing the url of the document library and not the destination file itself.
i.e. try
http://server name/document library name/new file name.doc
However I am 100% sure this was not my case, since I checked the WebRequest's URI property several times and the URI was complete with filename, and all the folders in the path existed on the sharepoint site.
Anyways, I hope this helps someone.
If you're using a recent Django, changelist 9530 introduced an {% empty %} block, allowing you to write
{% for athlete in athlete_list %}
...
{% empty %}
No athletes
{% endfor %}
Useful when the something that you want to do involves special treatment for lists that might be empty.
This is not exactly a solution, but for opening new files this works great:
https://github.com/skuroda/Sublime-AdvancedNewFile
Command + Option + n
to save a file in a new or existing directory.
So this would place your_file.html.erb in the existing views directory in a Rails app. If you needed a new directory -you would just type that as the path and then hit enter.
You can also Tab
like in terminal to autocomplete for existing directories.
This does not give the sidebar navigation I am looking for, but at least helps with one significant need that is repeated often.
using(var client = new System.Net.WebClient()) {
client.UploadData(address,"PUT",data);
}
jquerys 'beforeunload' worked great for me
$(window).bind('beforeunload', function(){
if( $('input').val() !== '' ){
return "It looks like you have input you haven't submitted."
}
});
You can also make additions to this path with the PYTHONPATH environment variable at runtime, in addition to:
import sys
sys.path.append('/home/user/python-libs')
The view (blade template): Inside the loop you can retrieve whatever column you looking for
@foreach ($products as $product)
{{$product->sku}}
@endforeach
(Edited to improve answer)
First define a function get_latest_file
def get_latest_file(path, *paths):
fullpath = os.path.join(path, paths)
...
get_latest_file('example', 'files','randomtext011.*.txt')
You may also use a docstring !
def get_latest_file(path, *paths):
"""Returns the name of the latest (most recent) file
of the joined path(s)"""
fullpath = os.path.join(path, *paths)
If you use Python 3, you can use iglob instead.
Complete code to return the name of latest file:
def get_latest_file(path, *paths):
"""Returns the name of the latest (most recent) file
of the joined path(s)"""
fullpath = os.path.join(path, *paths)
files = glob.glob(fullpath) # You may use iglob in Python3
if not files: # I prefer using the negation
return None # because it behaves like a shortcut
latest_file = max(files, key=os.path.getctime)
_, filename = os.path.split(latest_file)
return filename
You may use:
To create array of objects:
var source = ['left', 'top'];
const result = source.map(arrValue => ({[arrValue]: 0}));
Demo:
var source = ['left', 'top'];_x000D_
_x000D_
const result = source.map(value => ({[value]: 0}));_x000D_
_x000D_
console.log(result);
_x000D_
Or if you wants to create a single object from values of arrays:
var source = ['left', 'top'];
const result = source.reduce((obj, arrValue) => (obj[arrValue] = 0, obj), {});
Demo:
var source = ['left', 'top'];_x000D_
_x000D_
const result = source.reduce((obj, arrValue) => (obj[arrValue] = 0, obj), {});_x000D_
_x000D_
console.log(result);

Bootstrap 3 has been released since this question was originally answered in January, so if you are a BS3 user, please refer to the BS3 documentation. For those still on BS2, the original answer still applies. If you are interested in switching from 2 to 3, see the migration guide.
From the bootstrap 2 docs:
Make any row "fluid" by changing .row to .row-fluid. The column classes stay the exact same, making it easy to flip between fixed and fluid grids.
Code
<div class="row-fluid">
<div class="span4">...</div>
<div class="span8">...</div>
</div>
This, in conjunction with setting the width of your container to a fluid value, should allow you to get your desired layout.
Add the following CSS;
.modal .modal-dialog .modal-content{ background-color: #d4c484; }
<div class="modal fade">
<div class="modal-dialog" role="document">
<div class="modal-content">
...
...
[^\x00-\x7F]
and [^[:ascii:]]
miss some control bytes so strings can be the better option sometimes. For example cat test.torrent | perl -pe 's/[^[:ascii:]]+/\n/g'
will do odd things to your terminal, where as strings test.torrent
will behave.
SleepEx
function (see http://msdn.microsoft.com/en-us/library/ms686307.aspx) is the best choise if your program directly or indirectly creates windows (for example use some COM objects). In the simples cases you can also use Sleep
.
Have you tried implementing InitializingBean
? It sounds like exactly what you're after.
The downside is that your bean becomes Spring-aware, but in most applications that's not so bad.
Since bash
5.0 (released on 7 Jan 2019) you can use the built-in variable EPOCHSECONDS
.
$ echo $EPOCHSECONDS
1547624774
There is also EPOCHREALTIME
which includes fractions of seconds.
$ echo $EPOCHREALTIME
1547624774.371215
EPOCHREALTIME
can be converted to micro-seconds (µs) by removing the decimal point. This might be of interest when using bash
's built-in arithmetic (( expression ))
which can only handle integers.
$ echo ${EPOCHREALTIME/./}
1547624774371215
In all examples from above the printed time values are equal for better readability. In reality the time values would differ since each command takes a small amount of time to be executed.
Try this:
foreach(GridViewRow row in GridView1.Rows) {
if(row.RowType == DataControlRowType.DataRow) {
HyperLink myHyperLink = row.FindControl("myHyperLinkID") as HyperLink;
}
}
If you are handling RowDataBound event, it's like this:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink;
}
}
function setSelectedIndex(s, v) {
for ( var i = 0; i < s.options.length; i++ ) {
if ( s.options[i].value == v ) {
s.options[i].selected = true;
return;
}
}
}
Where s is the dropdown and v is the value
As others have stated, there is no portable function that works on all systems. You can partially circumvent this with simple ifdef
:
#include <stdio.h>
#ifdef _WIN32
#include <string.h>
#define strcasecmp _stricmp
#else // assuming POSIX or BSD compliant system
#include <strings.h>
#endif
int main() {
printf("%d", strcasecmp("teSt", "TEst"));
}
All the answers here suggest to use ipairs but beware, it does not work all the time.
t = {[2] = 44, [4]=77, [6]=88}
--This for loop prints the table
for key,value in next,t,nil do
print(key,value)
end
--This one does not print the table
for key,value in ipairs(t) do
print(key,value)
end

I am contributing the modern answer. The answer by Bohemian is correct and was a good answer when it was written 6 years ago. Now the notoriously troublesome SimpleDateFormat
class is long outdated and we have so much better in java.time
, the modern Java date and time API. I warmly recommend you use this instead of the old date-time classes.
When I parse 08/16/2011
using your snippet, I get Sun Jan 16 00:08:00 CET 2011
. Since lowercase mm
is for minutes, I get 00:08:00
(8 minutes past midnight), and since uppercase DD
is for day of year, I get 16 January.
In java.time
too format pattern strings are case sensitive, and we needed to use uppercase MM
for month and lowercase dd for day of month.
Yes, java.time
works nicely on Java 6 and later and on both older and newer Android devices.

The question specifically states the performance needs to be improved for ad-hoc queries, and that indexes can't be added. So taking that at face value, what can be done to improve performance on any table?
Since we're considering ad-hoc queries, the WHERE clause and the ORDER BY clause can contain any combination of columns. This means that almost regardless of what indexes are placed on the table there will be some queries that require a table scan, as seen above in query plan of a poorly performing query.
Taking this into account, let's assume there are no indexes at all on the table apart from a clustered index on the primary key. Now let's consider what options we have to maximize performance.
Defragment the table
As long as we have a clustered index then we can defragment the table using DBCC INDEXDEFRAG (deprecated) or preferably ALTER INDEX. This will minimize the number of disk reads required to scan the table and will improve speed.
Use the fastest disks possible. You don't say what disks you're using but if you can use SSDs.
Optimize tempdb. Put tempdb on the fastest disks possible, again SSDs. See this SO Article and this RedGate article.
As stated in other answers, using a more selective query will return less data, and should be therefore be faster.
Now let's consider what we can do if we are allowed to add indexes.
If we weren't talking about ad-hoc queries, then we would add indexes specifically for the limited set of queries being run against the table. Since we are discussing ad-hoc queries, what can be done to improve speed most of the time?
Edit
I've run some tests on a 'large' table of 22 million rows. My table only has six columns but does contain 4GB of data. My machine is a respectable desktop with 8Gb RAM and a quad core CPU and has a single Agility 3 SSD.
I removed all indexes apart from the primary key on the Id column.
A similar query to the problem one given in the question takes 5 seconds if SQL server is restarted first and 3 seconds subsequently. The database tuning advisor obviously recommends adding an index to improve this query, with an estimated improvement of > 99%. Adding an index results in a query time of effectively zero.
What's also interesting is that my query plan is identical to yours (with the clustered index scan), but the index scan accounts for 9% of the query cost and the sort the remaining 91%. I can only assume your table contains an enormous amount of data and/or your disks are very slow or located over a very slow network connection.
javax.servlet.Filter
.doFilter()
method, cast the incoming ServletRequest
to HttpServletRequest
.HttpServletRequest#getRequestURI()
to grab the path.java.lang.String
methods like substring()
, split()
, concat()
and so on to extract the part of interest and compose the new path.ServletRequest#getRequestDispatcher()
and then RequestDispatcher#forward()
to forward the request/response to the new URL (server-side redirect, not reflected in browser address bar), or cast the incoming ServletResponse
to HttpServletResponse
and then HttpServletResponse#sendRedirect()
to redirect the response to the new URL (client side redirect, reflected in browser address bar).web.xml
on an url-pattern
of /*
or /Check_License/*
, depending on the context path, or if you're on Servlet 3.0 already, use the @WebFilter
annotation for that instead.Don't forget to add a check in the code if the URL needs to be changed and if not, then just call FilterChain#doFilter()
, else it will call itself in an infinite loop.
Alternatively you can also just use an existing 3rd party API to do all the work for you, such as Tuckey's UrlRewriteFilter which can be configured the way as you would do with Apache's mod_rewrite
.
First install the rjson
package:
install.packages("rjson")
Then:
library("rjson")
json_file <- "http://api.worldbank.org/country?per_page=10®ion=OED&lendingtype=LNX&format=json"
json_data <- fromJSON(paste(readLines(json_file), collapse=""))
Update: since version 0.2.1
json_data <- fromJSON(file=json_file)
Try in yourbatch

I know its been a while since the question was asked but I was able to find a solution:
int sockfd;
int option = 1;
sockfd = socket(AF_INET, SOCK_STREAM, 0);
setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &option, sizeof(option));
This set the socket able to be reused immediately.
I apologize if this is "wrong". I'm not very experienced with sockets
While saving the response of get request, same error was thrown on Python 3.7 on window 10. The response received from the URL, encoding was UTF-8 so it is always recommended to check the encoding so same can be passed to avoid such trivial issue as it really kills lots of time in production
import requests
resp = requests.get('https://en.wikipedia.org/wiki/NIFTY_50')
print(resp.encoding)
with open ('NiftyList.txt', 'w') as f:
f.write(resp.text)
When I added encoding="utf-8" with the open command it saved the file with the correct response
with open ('NiftyList.txt', 'w', encoding="utf-8") as f:
f.write(resp.text)
This code will remove the indentation and list bullets.

The default modal presentation style is a card. This shows the previous view controller at the top and allows the user to swipe away the presented view controller.
To retain the old style you need to modify the view controller you will be presenting like this:
newViewController.modalPresentationStyle = .fullScreen
This is the same for both programmatically created and storyboard created controllers.
Swift 3
With a programmatically created Controller
If you want to navigate to Controller created Programmatically, then do this:
let newViewController = NewViewController()
self.navigationController?.pushViewController(newViewController, animated: true)
With a StoryBoard created Controller
If you want to navigate to Controller on StoryBoard with Identifier "newViewController", then do this:
let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewController = storyBoard.instantiateViewController(withIdentifier: "newViewController") as! NewViewController
self.present(newViewController, animated: true, completion: nil)
With SQLServer 2005 Express, what I found was that even with autocommit off, insertions into a Db table were committed without my actually issuing a commit command from the Management Studio session. The only difference was, when autocommit was off, I could roll back all the insertions; with *autocommit on, I could not.* Actually, I was wrong. With autocommit mode off, I see the changes only in the QA (Query Analyzer) window from which the commands were issued. If I popped a new QA (Query Analyzer) window, I do not see the changes made by the first window (session), i.e. they are NOT committed! I had to issue explicit commit or rollback commands to make changes visible to other sessions(QA windows) -- my bad! Things are working correctly.
Try to create a new empty project; then you can copy the public_html to the new project folder and it will appear .
You can use Electron, it allows hybrid browserjs and nodejs.
Before, I tried to use canvas2d in nodejs, but finally I gave up. It's not supported by nodejs default, and too hard to install it (many many ... dependeces). Until I use Electron, I can easily use all my previous browserjs code, even WebGL, and pass the result value(eg. result base64 image data) to nodejs code.
You can see if it's really not set. Run the command set | grep TERM
.
If not, you can set it like that:
export TERM=xterm
It seems the answers here do not support an enterprise use case where a Nexus server has multiple users and has project-based isolation (protection) based on user id ALONG with using an automated build (CI) system like Jenkins. You would not be able to create a settings.xml file to satisfy the different user ids needed for different projects. I am not sure how to solve this, except by opening Nexus up to anonymous access for reading repositories, unless the projects could store a project-specific generic user id in their pom.xml.
If by array of String you mean array of char:
public class Test
{
public static void main(String[] args)
{
String test = "aabbab ";
char[] t = test.toCharArray();
for(char c : t)
System.out.println(c);
System.out.println("The end!");
}
}
If not, the String.split()
function could transform a String into an array of String
See those String.split
examples
/* String to split. */
String str = "one-two-three";
String[] temp;
/* delimiter */
String delimiter = "-";
/* given string will be split by the argument delimiter provided. */
temp = str.split(delimiter);
/* print substrings */
for(int i =0; i < temp.length ; i++)
System.out.println(temp[i]);
The input.split("(?!^)")
proposed by Joachim in his answer is based on:
?!
' zero-width negative lookahead (see Lookaround)^
' as an Anchor to match the start of the string the regex pattern is applied toAny character which is not the first will be split. An empty string will not be split but return an empty array.
Old question but appears to have a lot of traffic, here is a simple solution:
IntPtr GetMainWindowHandle(IntPtr aHandle) {
return System.Diagnostics.Process.GetProcessById(aHandle.ToInt32()).MainWindowHandle;
}
max
function is used to get the maximum out of an iterable
.
The iterators may be lists, tuples, dict objects, etc. Or even custom objects as in the example you provided.
max(iterable[, key=func]) -> value
max(a, b, c, ...[, key=func]) -> value
With a single iterable argument, return its largest item.
With two or more arguments, return the largest argument.
So, the key=func
basically allows us to pass an optional argument key
to the function on whose basis is the given iterator/arguments are sorted & the maximum is returned.
lambda
is a python keyword that acts as a pseudo function. So, when you pass player
object to it, it will return player.totalScore
. Thus, the iterable passed over to function max
will sort according to the key
totalScore of the player
objects given to it & will return the player
who has maximum totalScore
.
If no key
argument is provided, the maximum is returned according to default Python orderings.
Examples -
max(1, 3, 5, 7)
>>>7
max([1, 3, 5, 7])
>>>7
people = [('Barack', 'Obama'), ('Oprah', 'Winfrey'), ('Mahatma', 'Gandhi')]
max(people, key=lambda x: x[1])
>>>('Oprah', 'Winfrey')

Using padding is not correct way of doing it, it may change the look but it is not what you wanted. This may solve your issue.
This problem happens because IIS does not find the actual location of woff2 file mime types. Set URL of font-face properly, also keep font-family as glyphicons-halflings-regular in your CSS file as shown below.

I'd use a UIViewController subclass containing a "Container View" that embeds your others view controllers. You'll then be able to add the navigation controller inside the Container View (using the embed relationship segue for example).

The stemmer vs lemmatizer debates goes on. It's a matter of preferring precision over efficiency. You should lemmatize to achieve linguistically meaningful units and stem to use minimal computing juice and still index a word and its variations under the same key.
Here's an example with python NLTK:
>>> sent = "cats running ran cactus cactuses cacti community communities"
>>> from nltk.stem import PorterStemmer, WordNetLemmatizer
>>>
>>> port = PorterStemmer()
>>> " ".join([port.stem(i) for i in sent.split()])
'cat run ran cactu cactus cacti commun commun'
>>>
>>> wnl = WordNetLemmatizer()
>>> " ".join([wnl.lemmatize(i) for i in sent.split()])
'cat running ran cactus cactus cactus community community'
When the normType
is NORM_MINMAX
, cv::normalize
normalizes _src
in such a way that the min value of dst
is alpha
and max value of dst
is beta
. cv::normalize
does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).
CV_8UC1
says how many channels dst
has.
The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize
I assume your game has a main loop, and all your sprites are in a list called sprites
.
In your main loop, get all events, and check for the MOUSEBUTTONDOWN
or MOUSEBUTTONUP
event.
while ... # your main loop
# get all events
ev = pygame.event.get()
# proceed events
for event in ev:
# handle MOUSEBUTTONUP
if event.type == pygame.MOUSEBUTTONUP:
pos = pygame.mouse.get_pos()
# get a list of all sprites that are under the mouse cursor
clicked_sprites = [s for s in sprites if s.rect.collidepoint(pos)]
# do something with the clicked sprites...
So basically you have to check for a click on a sprite yourself every iteration of the mainloop. You'll want to use mouse.get_pos() and rect.collidepoint().
Pygame does not offer event driven programming, as e.g. cocos2d does.
Another way would be to check the position of the mouse cursor and the state of the pressed buttons, but this approach has some issues.
if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()):
print ("You have opened a chest!")
You'll have to introduce some kind of flag if you handled this case, since otherwise this code will print "You have opened a chest!" every iteration of the main loop.
handled = False
while ... // your loop
if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()) and not handled:
print ("You have opened a chest!")
handled = pygame.mouse.get_pressed()[0]
Of course you can subclass Sprite
and add a method called is_clicked
like this:
class MySprite(Sprite):
...
def is_clicked(self):
return pygame.mouse.get_pressed()[0] and self.rect.collidepoint(pygame.mouse.get_pos())
So, it's better to use the first approach IMHO.
If you want to write the output to a file you can use the stdout-argument of subprocess.call
.
It takes None
, subprocess.PIPE
, a file object or a file descriptor. The first is the default, stdout is inherited from the parent (your script). The second allows you to pipe from one command/process to another. The third and fourth are what you want, to have the output written to a file.
You need to open a file with something like open
and pass the object or file descriptor integer to call
:
f = open("blah.txt", "w")
subprocess.call(["/home/myuser/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], stdout=f)
I'm guessing any valid file-like object would work, like a socket (gasp :)), but I've never tried.
As marcog mentions in the comments you might want to redirect stderr as well, you can redirect this to the same location as stdout with stderr=subprocess.STDOUT
. Any of the above mentioned values works as well, you can redirect to different places.
Like Unix shells, PowerShell supports >
redirects with most of the variations known from Unix, including 2>&1
(though weirdly, order doesn't matter - 2>&1 > file
works just like the normal > file 2>&1
).
Like most modern Unix shells, PowerShell also has a shortcut for redirecting both standard error and standard output to the same device, though unlike other redirection shortcuts that follow pretty much the Unix convention, the capture all shortcut uses a new sigil and is written like so: *>
.
So your implementation might be:
& myjob.bat *>> $logfile
If it's a server socket, you should call listen()
on your socket, and then getsockname()
to find the port number on which it is listening:
struct sockaddr_in sin;
socklen_t len = sizeof(sin);
if (getsockname(sock, (struct sockaddr *)&sin, &len) == -1)
perror("getsockname");
else
printf("port number %d\n", ntohs(sin.sin_port));
As for the IP address, if you use INADDR_ANY
then the server socket can accept connections to any of the machine's IP addresses and the server socket itself does not have a specific IP address. For example if your machine has two IP addresses then you might get two incoming connections on this server socket, each with a different local IP address. You can use getsockname()
on the socket for a specific connection (which you get from accept()
) in order to find out which local IP address is being used on that connection.
You have 3 options to make your way:
1. Define a date value like '1970-01-01'
2. Select NULL from the dropdown to keep it blank.
3. Select CURRENT_TIMESTAMP to set current datetime as default value.
A quick answer, that doesn't require you to edit any configuration files (and works on other operating systems as well as Windows), is to just find the directory that you are allowed to save to using:
mysql> SHOW VARIABLES LIKE "secure_file_priv";
+------------------+-----------------------+
| Variable_name | Value |
+------------------+-----------------------+
| secure_file_priv | /var/lib/mysql-files/ |
+------------------+-----------------------+
1 row in set (0.06 sec)
And then make sure you use that directory in your SELECT
statement's INTO OUTFILE
clause:
SELECT *
FROM xxxx
WHERE XXX
INTO OUTFILE '/var/lib/mysql-files/report.csv'
FIELDS TERMINATED BY '#'
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
Original answer
I've had the same problem since upgrading from MySQL 5.6.25 to 5.6.26.
In my case (on Windows), looking at the MySQL56 Windows service shows me that the options/settings file that is being used when the service starts is C:\ProgramData\MySQL\MySQL Server 5.6\my.ini
On linux the two most common locations are /etc/my.cnf
or /etc/mysql/my.cnf
.
Opening this file I can see that the secure-file-priv
option has been added under the [mysqld]
group in this new version of MySQL Server with a default value:
secure-file-priv="C:/ProgramData/MySQL/MySQL Server 5.6/Uploads"
You could comment this (if you're in a non-production environment), or experiment with changing the setting (recently I had to set secure-file-priv = ""
in order to disable the default). Don't forget to restart the service after making changes.
Alternatively, you could try saving your output into the permitted folder (the location may vary depending on your installation):
SELECT *
FROM xxxx
WHERE XXX
INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 5.6/Uploads/report.csv'
FIELDS TERMINATED BY '#'
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
It's more common to have comma seperate values using FIELDS TERMINATED BY ','
. See below for an example (also showing a Linux path):
SELECT *
FROM table
INTO OUTFILE '/var/lib/mysql-files/report.csv'
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
ESCAPED BY ''
LINES TERMINATED BY '\n';
If both your client and service is installed on the same machine, and you are facing this problem with the correct (read: tried and tested elsewhere) client and service configurations, then this might be worth checking.
Check host entries in your host file
%windir%/system32/drivers/etc/hosts
Check to see if you are accessing your web service with a hostname, and that same hostname has been associated with an IP address in the hosts file mentioned above. If yes, NTLM/Windows credentials will NOT be passed from the client to the service as any request for that hostname will be routed again at the machine level.
Try either of the following
Edit: Somehow the above situation is relevant on a load-balanced scenario. However, if removing the host entries is not possible, then disabling loop back check on the machine will help. Refer method 2 in the article https://support.microsoft.com/en-us/kb/896861
The xmlhttp request method is not valid for the files on local disk because the browser security does not allow us to do so.But we can override the browser security by creating a shortcut->right click->properties In target "... browser location path.exe" append --allow-file-access-from-files.This is tested on chrome,however care should be taken that all browser windows should be closed and the code should be run from the browser opened via this shortcut.
I constantly forget the names of the colors I want to use and keep coming back to this question =)
The previous answers are great, but I find it a bit difficult to get an overview of the available colors from the posted image. I prefer the colors to be grouped with similar colors, so I slightly tweaked the matplotlib answer that was mentioned in a comment above to get a color list sorted in columns. The order is not identical to how I would sort by eye, but I think it gives a good overview.
I updated the image and code to reflect that 'rebeccapurple' has been added and the three sage colors have been moved under the 'xkcd:' prefix since I posted this answer originally.
I really didn't change much from the matplotlib example, but here is the code for completeness.
import matplotlib.pyplot as plt
from matplotlib import colors as mcolors
colors = dict(mcolors.BASE_COLORS, **mcolors.CSS4_COLORS)
# Sort colors by hue, saturation, value and name.
by_hsv = sorted((tuple(mcolors.rgb_to_hsv(mcolors.to_rgba(color)[:3])), name)
for name, color in colors.items())
sorted_names = [name for hsv, name in by_hsv]
n = len(sorted_names)
ncols = 4
nrows = n // ncols
fig, ax = plt.subplots(figsize=(12, 10))
# Get height and width
X, Y = fig.get_dpi() * fig.get_size_inches()
h = Y / (nrows + 1)
w = X / ncols
for i, name in enumerate(sorted_names):
row = i % nrows
col = i // nrows
y = Y - (row * h) - h
xi_line = w * (col + 0.05)
xf_line = w * (col + 0.25)
xi_text = w * (col + 0.3)
ax.text(xi_text, y, name, fontsize=(h * 0.8),
horizontalalignment='left',
verticalalignment='center')
ax.hlines(y + h * 0.1, xi_line, xf_line,
color=colors[name], linewidth=(h * 0.8))
ax.set_xlim(0, X)
ax.set_ylim(0, Y)
ax.set_axis_off()
fig.subplots_adjust(left=0, right=1,
top=1, bottom=0,
hspace=0, wspace=0)
plt.show()
Updated 2017-10-25. I merged my previous updates into this section.
If you would like to use additional named colors when plotting with matplotlib, you can use the xkcd crowdsourced color names, via the 'xkcd:' prefix:
plt.plot([1,2], lw=4, c='xkcd:baby poop green')
Now you have access to a plethora of named colors!
The default Tableau colors are available in matplotlib via the 'tab:' prefix:
plt.plot([1,2], lw=4, c='tab:green')
There are ten distinct colors:
You can also plot colors by their HTML hex code:
plt.plot([1,2], lw=4, c='#8f9805')
This is more similar to specifying and RGB tuple rather than a named color (apart from the fact that the hex code is passed as a string), and I will not include an image of the 16 million colors you can choose from...
For more details, please refer to the matplotlib colors documentation and the source file specifying the available colors, _color_data.py
.
This is a simpler mechanism. It simply involves the addition of a Windows Batch command task build step before the MSBuild step and the use of a simple find and replace program (FART).
The Batch Step
fart --svn -r AssemblyInfo.cs "[assembly: AssemblyVersion(\"1.0.0.0\")]" "[assembly: AssemblyVersion(\"1.0.%BUILD_NUMBER%.%SVN_REVISION%\")]"
if %ERRORLEVEL%==0 exit /b 1
fart --svn -r AssemblyInfo.cs "[assembly: AssemblyFileVersion(\"1.0.0.0\")]" "[assembly: AssemblyFileVersion(\"1.0.%BUILD_NUMBER%.%SVN_REVISION%\")]"
if %ERRORLEVEL%==0 exit /b 1
exit /b 0
If you are using source control other than svn change the --svn option for the appropriate one for your scm environment.
Don't declare the variable in the userform. Declare it as Public
in the module.
Public pass As String
In the Userform
Private Sub CommandButton1_Click()
pass = UserForm1.TextBox1
Unload UserForm1
End Sub
In the Module
Public pass As String
Public Sub Login()
'
'~~> Rest of the code
'
UserForm1.Show
driver.findElementByName("PASSWORD").SendKeys pass
'
'~~> Rest of the code
'
End Sub
You might want to also add an additional check just before calling the driver.find...
line?
If Len(Trim(pass)) <> 0 Then
This will ensure that a blank string is not passed.

Now that that's out of the way, most of the following is meant as commentary on how complex regex can get if you try to be clever with it, and why you should seek alternatives. Read at your own risk.
This is a very common task, but all the answers I see here so far will accept inputs that don't match your number format, such as ,111
, 9,9,9
, or even .,,.
. That's simple enough to fix, even if the numbers are embedded in other text. IMHO anything that fails to pull 1,234.56 and 1234—and only those numbers—out of abc22 1,234.56 9.9.9.9 def 1234
is a wrong answer.
First of all, if you don't need to do this all in one regex, don't. A single regex for two different number formats is hard to maintain even when they aren't embedded in other text. What you should really do is split the whole thing on whitespace, then run two or three smaller regexes on the results. If that's not an option for you, keep reading.
Considering the examples you've given, here's a simple regex that allows pretty much any integer or decimal in 0000
format and blocks everything else:
^\d*\.?\d+$
Here's one that requires 0,000
format:
^\d{1,3}(,\d{3})*(\.\d+)?$
Put them together, and commas become optional as long as they're consistent:
^(\d*\.?\d+|\d{1,3}(,\d{3})*(\.\d+)?)$
The patterns above require the entire input to be a number. You're looking for numbers embedded in text, so you have to loosen that part. On the other hand, you don't want it to see catch22
and think it's found the number 22. If you're using something with lookbehind support (like .NET), this is pretty easy: replace ^
with (?<!\S)
and $
with (?!\S)
and you're good to go:
(?<!\S)(\d*\.?\d+|\d{1,3}(,\d{3})*(\.\d+)?)(?!\S)
If you're working with JavaScript or Ruby or something, things start looking more complex:
(?:^|\s)(\d*\.?\d+|\d{1,3}(?:,\d{3})*(?:\.\d+)?)(?!\S)
You'll have to use capture groups; I can't think of an alternative without lookbehind support. The numbers you want will be in Group 1 (assuming the whole match is Group 0).
I think that covers your question, so if that's all you need, stop reading now. If you want to get fancier, things turn very complex very quickly. Depending on your situation, you may want to block any or all of the following:
Just for the hell of it, let's assume you want to block the first 3, but allow the last one. What should you do? I'll tell you what you should do, you should use a different regex for each rule and progressively narrow down your matches. But for the sake of the challenge, here's how you do it all in one giant pattern:
(?<!\S)(?=.)(0|([1-9](\d*|\d{0,2}(,\d{3})*)))?(\.\d*[1-9])?(?!\S)
And here's what it means:
(?<!\S) to (?!\S) #The whole match must be surrounded by either whitespace or line boundaries. So if you see something bogus like :;:9.:, ignore the 9.
(?=.) #The whole thing can't be blank.
( #Rules for the integer part:
0 #1. The integer part could just be 0...
| #
[1-9] # ...otherwise, it can't have leading zeroes.
( #
\d* #2. It could use no commas at all...
| #
\d{0,2}(,\d{3})* # ...or it could be comma-separated groups of 3 digits each.
) #
)? #3. Or there could be no integer part at all.
( #Rules for the decimal part:
\. #1. It must start with a decimal point...
\d* #2. ...followed by a string of numeric digits only.
[1-9] #3. It can't be just the decimal point, and it can't end in 0.
)? #4. The whole decimal part is also optional. Remember, we checked at the beginning to make sure the whole thing wasn't blank.

This will allow things like:
100,000
999.999
90.0009
1,000,023.999
0.111
.111
0
It will block things like:
1,1,1.111
000,001.111
999.
0.
111.110000
1.1.1.111
9.909,888
There are several ways to make this regex simpler and shorter, but understand that changing the pattern will loosen what it considers a number.
Since many regex engines (e.g. JavaScript and Ruby) don't support the negative lookbehind, the only way to do this correctly is with capture groups:
(:?^|\s)(?=.)((?:0|(?:[1-9](?:\d*|\d{0,2}(?:,\d{3})*)))?(?:\.\d*[1-9])?)(?!\S)
The numbers you're looking for will be in capture group 1.

Obviously, this is a massive, complicated, nigh-unreadable regex. I enjoyed the challenge, but you should consider whether you really want to use this in a production environment. Instead of trying to do everything in one step, you could do it in two: a regex to catch anything that might be a number, then another one to weed out whatever isn't a number. Or you could do some basic processing, then use your language's built-in number parsing functions. Your choice.

Be careful when accessing DateTime.Now twice, as it's possible for the calls to straddle midnight and you'll get wacky results on rare occasions and be left scratching your head.
To be safe, you should assign DateTime.Now to a local variable first if you're going to use it more than once:
var now = DateTime.Now;
var time = now.ToString("hh:mm:ss tt");
var date = now.ToString("MM/dd/yy");
Note the use of lower case "hh" do display hours from 00-11 even in the afternoon, and "tt" to show AM/PM, as the question requested. If you want 24 hour clock 00-23, use "HH".
Modules are by no means deprecated and are used heavily in the VB language. It's the only way for instance to implement an extension method in VB.Net.
There is one huge difference between Modules and Classes with Static Members. Any method defined on a Module is globally accessible as long as the Module is available in the current namespace. In effect a Module allows you to define global methods. This is something that a class with only shared members cannot do.
Here's a quick example that I use a lot when writing VB code that interops with raw COM interfaces.
Module Interop
Public Function Succeeded(ByVal hr as Integer) As Boolean
...
End Function
Public Function Failed(ByVal hr As Integer) As Boolean
...
End Function
End Module
Class SomeClass
Sub Foo()
Dim hr = CallSomeHrMethod()
if Succeeded(hr) then
..
End If
End Sub
End Class
Varying is an alias for varchar, so no difference, see documentation :)
The notations varchar(n) and char(n) are aliases for character varying(n) and character(n), respectively. character without length specifier is equivalent to character(1). If character varying is used without length specifier, the type accepts strings of any size. The latter is a PostgreSQL extension.
