You need to use ScriptManager.RegisterStartupScript for Ajax.
protected void ButtonPP_Click(object sender, EventArgs e) { if (radioBtnACO.SelectedIndex < 0) { string csname1 = "PopupScript"; var cstext1 = new StringBuilder(); cstext1.Append("alert('Please Select Criteria!')"); ScriptManager.RegisterStartupScript(this, GetType(), csname1, cstext1.ToString(), true); } }
This works for me. Hope it will work for you too.
ScriptManager.RegisterStartupScript(this, this.GetType(), "isActive", "Test();", true);
I have edited the html page which you have provided. The updated page is as below
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>My Page</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
function Test() {
alert("Hello Test!!!!");
$('#ButtonRow').css("display", "block");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<table>
<tr>
<td>
<asp:RadioButtonList ID="SearchCategory" runat="server" RepeatDirection="Horizontal"
BorderStyle="Solid">
<asp:ListItem>Merchant</asp:ListItem>
<asp:ListItem>Store</asp:ListItem>
<asp:ListItem>Terminal</asp:ListItem>
</asp:RadioButtonList>
</td>
</tr>
<tr id="ButtonRow" style="display: none">
<td>
<asp:Button ID="MyButton" runat="server" Text="Click Here" OnClick="MyButton_Click" />
</td>
</tr>
</table>
</form>
</body>
</html>
<script type="text/javascript">
$("#<%=SearchCategory.ClientID%> input").change(function () {
alert("hi");
$("#ButtonRow").show();
});
</script>
Now we could also use:
if (Attachment != null && Attachment.Any())
Any() is often easier to understand in a glance for the developer than checking Length() > 0. Also has very little difference with processing speed.
Target= "_blank"
This does it in html, give it a try in C#
Or write to the response stream:
Response.Write("<script>");
Response.Write("window.open('page.html','_blank')");
Response.Write("</script>");
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;
}
}
I came across a similar issue. However this issue was caused because of the way i designed the pages to bring the requests in. I placed all of my .js files as the last thing to be applied to the page, therefore they are at the end of my document. The .js files have all my functions include. The script manager seems that to be able to call this function it needs the js file already present with the function being called at the time of load. Hope this helps anyone else.
XmlDocument doc = new XmlDocument();
doc.LoadXml(str);
Where str
is your XML string. See the MSDN article for more info.
ScriptManager.RegisterStartupScript(this, this.GetType(), Guid.NewGuid().ToString(),script, true );
The "true" param value at the end of the ScriptManager.RegisterStartupScript will add a JavaScript tag inside your page:
<script language='javascript' defer='defer'>your script</script >
If the value will be "false" it will inject only the script witout the --script-- tag.
Here's an old discussion thread where I listed the main differences and the conditions in which you should use each of these methods. I think you may find it useful to go through the discussion.
To explain the differences as relevant to your posted example:
a. When you use RegisterStartupScript
, it will render your script after all the elements in the page (right before the form's end tag). This enables the script to call or reference page elements without the possibility of it not finding them in the Page's DOM.
Here is the rendered source of the page when you invoke the RegisterStartupScript
method:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
<form name="form1" method="post" action="StartupScript.aspx" id="form1">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
</div>
<div> <span id="lblDisplayDate">Label</span>
<br />
<input type="submit" name="btnPostback" value="Register Startup Script" id="btnPostback" />
<br />
<input type="submit" name="btnPostBack2" value="Register" id="btnPostBack2" />
</div>
<div>
<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="someViewstategibberish" />
</div>
<!-- Note this part -->
<script language='javascript'>
var lbl = document.getElementById('lblDisplayDate');
lbl.style.color = 'red';
</script>
</form>
<!-- Note this part -->
</body>
</html>
b. When you use RegisterClientScriptBlock
, the script is rendered right after the Viewstate tag, but before any of the page elements. Since this is a direct script (not a function that can be called, it will immediately be executed by the browser. But the browser does not find the label in the Page's DOM at this stage and hence you should receive an "Object not found" error.
Here is the rendered source of the page when you invoke the RegisterClientScriptBlock
method:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
<form name="form1" method="post" action="StartupScript.aspx" id="form1">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
</div>
<script language='javascript'>
var lbl = document.getElementById('lblDisplayDate');
// Error is thrown in the next line because lbl is null.
lbl.style.color = 'green';
Therefore, to summarize, you should call the latter method if you intend to render a function definition. You can then render the call to that function using the former method (or add a client side attribute).
Edit after comments:
For instance, the following function would work:
protected void btnPostBack2_Click(object sender, EventArgs e)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("<script language='javascript'>function ChangeColor() {");
sb.Append("var lbl = document.getElementById('lblDisplayDate');");
sb.Append("lbl.style.color='green';");
sb.Append("}</script>");
//Render the function definition.
if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock"))
{
ClientScript.RegisterClientScriptBlock(this.GetType(), "JSScriptBlock", sb.ToString());
}
//Render the function invocation.
string funcCall = "<script language='javascript'>ChangeColor();</script>";
if (!ClientScript.IsStartupScriptRegistered("JSScript"))
{
ClientScript.RegisterStartupScript(this.GetType(), "JSScript", funcCall);
}
}
This vbscript/batch hybrid "append_sys_path.vbs" is not intuitive but works perfectly:
If CreateObject("WScript.Shell").Run("%ComSpec% /C ""NET FILE""", 0, True) <> 0 Then
CreateObject("Shell.Application").ShellExecute WScript.FullName, """" & WScript.ScriptFullName & """", , "runas", 5
WScript.Quit
End If
Set Shell = CreateObject("WScript.Shell")
Cmd = Shell.Exec("%ComSpec% /C ""REG QUERY ""HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"" /v Path | FINDSTR /I /C:""REG_SZ"" /C:""REG_EXPAND_SZ""""").StdOut.ReadAll
Cmd = """" & Trim(Replace(Mid(Cmd, InStr(1, Cmd, "_SZ", VBTextCompare) + 3), vbCrLf, ""))
If Right(Cmd, 1) <> ";" Then Cmd = Cmd & ";"
Cmd = "%ComSpec% /C ""REG ADD ""HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"" /v Path /t REG_EXPAND_SZ /d " & Replace(Cmd & "%SystemDrive%\Python27;%SystemDrive%\Python27\Scripts"" /f""", "%", """%""")
Shell.Run Cmd, 0, True
Advantages of this approach:
1) It doesn't truncate the system path environment at 1024 characters.
2) It doesn't concatenate the system and user path environment.
3) It's automatically run as administrator.
4) Preserve the percentages in the system path environment.
5) Supports spaces, parentheses and special characters.
6) Works on Windows 7 and above.
I hate to point out the obvious, but System.IO.FileNotFoundException means the program did not find the file you specified. So what you need to do is check what file your code is looking for in production.
To see what file your program is looking for in production (look at the FileName property of the exception), try these techniques:
Then look at the file system on the machine and see if the file exists. Most likely the case is that it doesn't exist.
Simply create an instance of Class2
and call the desired method.

This may work for you. I used it for cleaning folders during deployments for deleting old deployment files.
clean_anyfolder() {
local temp2="$1/**"; //PATH
temp3=( $(ls -d $temp2 -t | grep "`date | awk '{print $2" "$3}'`") )
j=0;
while [ $j -lt ${#temp3[@]} ]
do
echo "to be removed ${temp3[$j]}"
delete_file_or_folder ${temp3[$j]} 0 //DELETE HERE
fi
j=`expr $j + 1`
done
}
Typically, boolean values that are used in branches immediately after they're calculated like this are never actually stored in variables. Instead, the compiler just branches directly off the condition codes that were set from the preceding comparison. For example,
int a = SomeFunction();
bool result = --a >= 0; // use subtraction as example computation
if ( result )
{
foo();
}
else
{
bar();
}
return;
Usually compiles to something like:
call .SomeFunction ; calls to SomeFunction(), which stores its return value in eax
sub eax, 1 ; subtract 1 from eax and store in eax, set S (sign) flag if result is negative
jl ELSEBLOCK ; GOTO label "ELSEBLOCK" if S flag is set
call .foo ; this is the "if" black, call foo()
j FINISH ; GOTO FINISH; skip over the "else" block
ELSEBLOCK: ; label this location to the assembler
call .bar
FINISH: ; both paths end up here
ret ; return
Notice how the "bool" is never actually stored anywhere.
withRouter
, history.listen
, and useEffect
(React Hooks) works quite nicely together:
import React, { useEffect } from 'react'
import { withRouter } from 'react-router-dom'
const Component = ({ history }) => {
useEffect(() => history.listen(() => {
// do something on route change
// for my example, close a drawer
}), [])
//...
}
export default withRouter(Component)
The listener callback will fire any time a route is changed, and the return for history.listen
is a shutdown handler that plays nicely with useEffect
.
Presumably you want this conversion for using functions from the C standard library.
In that case, do (C++ syntax)
typedef unsigned char UChar;
char myCppFunc( char c )
{
return char( someCFunc( UChar( c ) ) );
}
The expression UChar( c )
converts to unsigned char
in order to get rid of negative values, which, except for EOF, are not supported by the C functions.
Then the result of that expression is used as actual argument for an int
formal argument. Where you get automatic promotion to int
. You can alternatively write that last step explicitly, like int( UChar( c ) )
, but personally I find that too verbose.
Cheers & hth.,
There is no bidirectional map in the Java Standard API. Either you can maintain two maps yourself or use the BidiMap from Apache Collections.
Facebook is using LAMP structure. Facebook’s back-end services are written in a variety of different programming languages including C++, Java, Python, and Erlang and they are used according to requirement. With LAMP Facebook uses some technologies ,to support large number of requests, like
Memcache - It is a memory caching system that is used to speed up dynamic database-driven websites (like Facebook) by caching data and objects in RAM to reduce reading time. Memcache is Facebook’s primary form of caching and helps alleviate the database load. Having a caching system allows Facebook to be as fast as it is at recalling your data.
Thrift (protocol) - It is a lightweight remote procedure call framework for scalable cross-language services development. Thrift supports C++, PHP, Python, Perl, Java, Ruby, Erlang, and others.
Cassandra (database) - It is a database management system designed to handle large amounts of data spread out across many servers.
HipHop for PHP - It is a source code transformer for PHP script code and was created to save server resources. HipHop transforms PHP source code into optimized C++. After doing this, it uses g++ to compile it to machine code.
If we go into more detail, then answer to this question go longer. We can understand more from following posts:
r = read mode only
r+ = read/write mode
w = write mode only
w+ = read/write mode, if the file already exists override it (empty it)
So yes, if the file already exists w+ will erase the file and give you an empty file.
To define an array of strings it is more comfortable to use $var = @('User1 ', 'User2 ').
$servername = hostname
$smtpserver = 'localhost'
$emailTo = @('username1 <[email protected]>', 'username2<[email protected]>')
$emailFrom = 'SomeServer <[email protected]>'
Send-MailMessage -To $emailTo -Subject 'Low available memory' -Body 'Warning' -SmtpServer $smtpserver -From $emailFrom
In my case, I want the name of the renamed file to be unique, so I add a date-time stamp to the name. This way, the filename of the 'old' log is always unique:
if (File.Exists(clogfile))
{
Int64 fileSizeInBytes = new FileInfo(clogfile).Length;
if (fileSizeInBytes > 5000000)
{
string path = Path.GetFullPath(clogfile);
string filename = Path.GetFileNameWithoutExtension(clogfile);
System.IO.File.Move(clogfile, Path.Combine(path, string.Format("{0}{1}.log", filename, DateTime.Now.ToString("yyyyMMdd_HHmmss"))));
}
}
The move
instruction copies a value from one register to another. The li
instruction loads a specific numeric value into that register.
For the specific case of zero, you can use either the constant zero or the zero register to get that:
move $s0, $zero
li $s0, 0
There's no register that generates a value other than zero, though, so you'd have to use li
if you wanted some other number, like:
li $s0, 12345678
Update March 2015
Python 2.7.9 and later (on the Python 2 series), and Python 3.4 and later include pip by default, so you may have pip already.
If you don't, run this one line command on your prompt (which may require administrator access):
python -c "exec('try: from urllib2 import urlopen \nexcept: from urllib.request import urlopen');f=urlopen('https://bootstrap.pypa.io/get-pip.py').read();exec(f)"
It will install pip. If Setuptools is not already installed, get-pip.py
will install it for you too.
As mentioned in comments, the above command will download code from the Pip source code repository at GitHub, and dynamically run it at your environment. So be noticed that this is a shortcut of the steps download, inspect and run, all with a single command using Python itself. If you trust Pip, proceed without doubt.
Be sure that your Windows environment variable PATH includes Python's folders (for Python 2.7.x default install: C:\Python27
and C:\Python27\Scripts
, for Python 3.3x: C:\Python33
and C:\Python33\Scripts
, and so on).
Throwable.printStackTrace()
writes the stack trace to System.err
PrintStream. The System.err
stream and the underlying standard "error" output stream of the JVM process can be redirected by
System.setErr()
which changes the destination pointed to by System.err
./dev/null
.Inferring from the above, invoking Throwable.printStackTrace()
constitutes valid (not good/great) exception handling behavior, only
System.err
being reassigned throughout the duration of the application's lifetime,System.err
(and the JVM's standard error output stream).In most cases, the above conditions are not satisfied. One may not be aware of other code running in the JVM, and one cannot predict the size of the log file or the runtime duration of the process, and a well designed logging practice would revolve around writing "machine-parseable" log files (a preferable but optional feature in a logger) in a known destination, to aid in support.
Finally, one ought to remember that the output of Throwable.printStackTrace()
would definitely get interleaved with other content written to System.err
(and possibly even System.out
if both are redirected to the same file/device). This is an annoyance (for single-threaded apps) that one must deal with, for the data around exceptions is not easily parseable in such an event. Worse, it is highly likely that a multi-threaded application will produce very confusing logs as Throwable.printStackTrace()
is not thread-safe.
There is no synchronization mechanism to synchronize the writing of the stack trace to System.err
when multiple threads invoke Throwable.printStackTrace()
at the same time. Resolving this actually requires your code to synchronize on the monitor associated with System.err
(and also System.out
, if the destination file/device is the same), and that is rather heavy price to pay for log file sanity. To take an example, the ConsoleHandler
and StreamHandler
classes are responsible for appending log records to console, in the logging facility provided by java.util.logging
; the actual operation of publishing log records is synchronized - every thread that attempts to publish a log record must also acquire the lock on the monitor associated with the StreamHandler
instance. If you wish to have the same guarantee of having non-interleaved log records using System.out
/System.err
, you must ensure the same - the messages are published to these streams in a serializable manner.
Considering all of the above, and the very restricted scenarios in which Throwable.printStackTrace()
is actually useful, it often turns out that invoking it is a bad practice.
Extending the argument in the one of the previous paragraphs, it is also a poor choice to use Throwable.printStackTrace
in conjunction with a logger that writes to the console. This is in part, due to the reason that the logger would synchronize on a different monitor, while your application would (possibly, if you don't want interleaved log records) synchronize on a different monitor. The argument also holds good when you use two different loggers that write to the same destination, in your application.
*********** PARSE THE RESULT TO JSON OBJECT: JSON.prase(result.arrayOfObjects) ***********
I came to this page after I faced this issue. So, my issue was that the server is sending array of objects in the form of string. It is something like this:
when I printed result on console after getting from server it is string:
'arrayOfObject': '[
{'id': '123', 'designation': 'developer'},
{'id': '422', 'designation': 'lead'}
]'
So, I have to convert this string to JSON after getting it from server. Use method for parsing the result string that you receive from server:
JSON.parse(result.arrayOfObjects)

I fixed it with Datejs
This is alerting the first day:
var fd = Date.today().clearTime().moveToFirstDayOfMonth();
var firstday = fd.toString("MM/dd/yyyy");
alert(firstday);
This is for the last day:
var ld = Date.today().clearTime().moveToLastDayOfMonth();
var lastday = ld.toString("MM/dd/yyyy");
alert(lastday);
Hidden layers are used in accordance with the complexity of our data. If we have input data which is linearly separable then we need not to use hidden layer e.g. OR gate but if we have a non linearly seperable data then we need to use hidden layer for example ExOR logical gate. Number of nodes taken at any layer depends upon the degree of cross validation of our output.
Another way to do it would include using filter like this:
countries = list(filter(lambda x: str(x) != 'nan', countries))
The webpages on an online server reside in a location which looks somewhat like this: http://www.somerandomsite.com/index.php
Since xampp is Offline, it sets up a local server whose address is like this
http://localhost/
Basically, xampp sets up a server (apache and others) in your system. And all the files such as index.php, somethingelse.php, etc., reside in the xampp\htdocs\
folder.
The browser locates the server in localhost and will search through the above folder for any resources available in there.
So create any number of folders inside the "xampp\htdocs\" each folder thus forming a website (as you build it).
Sometimes apache won't even start. This is due to the clashing of ports with some applications. Some of them I commonly encounter is Skype. See to that it is killed completely and restart apache

I know that in SQL 2012 (may work in other versions) you can do the following:
That will give you a list of the top 1000 tables and then you can order it by data size etc.
YOur best bet is to fix the datbase design and add the identioty column to the table. Why do you havea table without one in the first place? Especially one with duplicate records! Clearly the database itself needs redesigning.
And why do you have to have this in a view, why isn't your solution with the temp table a valid solution? Views are not usually a really good thing to do to a perfectly nice database.
There seem to be a lot of solutions for Windows here but this is the simplest:
Tools -> Build System -> New Build System, type in the above, save as Browser.sublime-build
:
{
"cmd": "explorer $file"
}
Then go back to your HTML file. Tools -> Build System -> Browser. Then press CTRL-B
and the file will be opened in whatever browser is your system default browser.
I confirm the easiest way is to do this:

As mentioned above, the 11.1 drivers by default convert SQL DATE to Timestamp when reading from the database. This always was the right thing to do and the change in 9i was a mistake. The 11.1 drivers have reverted to the correct behavior. Even if you didn't set V8Compatible in your application you shouldn't see any difference in behavior in most cases. You may notice a difference if you use getObject to read a DATE column. The result will be a Timestamp rather than a Date. Since Timestamp is a subclass of Date this generally isn't a problem. Where you might notice a difference is if you relied on the conversion from DATE to Date to truncate the time component or if you do toString on the value. Otherwise the change should be transparent.
If for some reason your app is very sensitive to this change and you simply must have the 9i-10g behavior, there is a connection property you can set. Set mapDateToTimestamp to false and the driver will revert to the default 9i-10g behavior and map DATE to Date.
I've created a systematic approach to CSS development. This way I can utilize a standard that never changes. First I started with the 960 grid system. Then I created single lines of css for basic layouts, margins, padding, fonts and sizes. I then string them together as needed. This allows me to keep a consistent layout across all of my projects and utilize the same css files over and over. Because they are not specific. Here's an example: ----div class="c12 bg0 m10 p5 white fl"/div--- This means that the container is 12 columns across, utilizes bg0 has margins of 10px padding of 5 the text is white and it floats left. I could easily change this by removing or adding a new - What I call a "light" style- Instead of creating a single class with all these attributes; I simply combine the single styles as I code the page. This allows me to create any combination of styles and does not limit my creativity or cause me to create a massive number of styles that are similar. Your style sheets become a lot more manageable, minimized and allow you to re-use it over and over. This method I have found to be fantastic for rapid design. I also no longer design first in PSD but in the browser which also saves time. In addition because I have also created a naming system for my backgrounds and page design attributes I simply change out my image file when creating a new project.(bg0 = body background according to my naming system) That means that if I previously had a white background with one project simply changing it to black simply means that on the next project bg0 will be a black background or another image..... I have not found anything wrong with this method yet and it seems to work very well.
Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA. You need to make sure you have the proper ADODB reference [VBA Editor->Tools->References] and make sure you have Microsoft ActiveX Data Objects 2.8 Library checked, which is the second from the bottom row that is checked (I'm using Excel 2010 on Windows 7; you might have a slightly different ActiveX version, but it will still begin with Microsoft ActiveX):

Here is a use case... however I am not too concerned with the technicalities of why I should or not use 1 = 1.
I am writing a function, using pyodbc to retrieve some data from SQL Server. I was looking for a way to force a filler after the where
keyword in my code. This was a great suggestion indeed:
if _where == '': _where = '1=1'
...
...
...
cur.execute(f'select {predicate} from {table_name} where {_where}')
The reason is because I could not implement the keyword 'where' together inside the _where clause variable. So, I think using any dummy condition that evaluates to true would do as a filler.
IF
is a PL/SQL construct. If you are executing a query, you are using SQL not PL/SQL.
In SQL, you can use a CASE
statement in the query itself
SELECT DISTINCT a.item,
(CASE WHEN b.salesman = 'VIKKIE'
THEN 'ICKY'
ELSE b.salesman
END),
NVL(a.manufacturer,'Not Set') Manufacturer
FROM inv_items a,
arv_sales b
WHERE a.co = '100'
AND a.co = b.co
AND A.ITEM_KEY = b.item_key
AND a.item LIKE 'BX%'
AND b.salesman in ('01','15')
AND trans_date BETWEEN to_date('010113','mmddrr')
and to_date('011713','mmddrr')
ORDER BY a.item
Since you aren't doing any aggregation, you don't want a GROUP BY
in your query. Are you really sure that you need the DISTINCT
? People often throw that in haphazardly or add it when they are missing a join condition rather than considering whether it is really necessary to do the extra work to identify and remove duplicates.
Use this...
var all_matches = your_string.match(re);
console.log(all_matches)
It will return an array of all matches...That would work just fine.... But remember it won't take groups in account..It will just return the full matches...
My default dir was system32 when starting CMD. I then created a batch file in that directory to change dir to the one I was after.
This caused me to always call that bat when starting CMD every time. So I made a reg file & put this inside:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Command Processor]
"Autorun"="cd C:\\Users\\Me\\SomeFolder"
After saving it, I opened the file, clicked ok to merge with registry, and since then every time I open CMD, I get my dir
> I have a .key file which is PEM formatted private key file.
> ...
> Here's some asn1parse of the .key file...
That it appears OK with asn1parse
leads me to believe its not PEM encoded.
Is there anything more I can try?
Because it appears to be ASN.1, try:
$ openssl rsa -in server.key -inform DER -modulus -noout
Notice the -inform DER
to switch between encodings.
Based on the stacktrace, an intuit class com.intuit.ipp.aggcat.util.SAML2AssertionGenerator needs a saml jar on the classpath.
A saml class org.opensaml.xml.XMLConfigurator needs on it's turn log4j, which is inside the WAR but cannot find it.
One explanation for this is that the class XMLConfigurator that needs log4j was found not inside the WAR but on a downstream classloader. could a saml jar be missing from the WAR?
The class XMLConfigurator that needs log4j cannot find it at the level of the classloader that loaded it, and the log4j version on the WAR is not visible on that particular classloader.
In order to troubleshoot this, a way is to add this before the oauth call:
System.out.println("all versions of log4j Logger: " + getClass().getClassLoader().getResources("org/apache/log4j/Logger.class") );
System.out.println("all versions of XMLConfigurator: " + getClass().getClassLoader().getResources("org/opensaml/xml/XMLConfigurator.class") );
System.out.println("all versions of XMLConfigurator visible from the classloader of the OAuthAuthorizer class: " + OAuthAuthorizer.class.getClassLoader().getResources("org/opensaml/xml/XMLConfigurator.class") );
System.out.println("all versions of log4j visible from the classloader of the OAuthAuthorizer class: " + OAuthAuthorizer.class.getClassloader().getResources("org/apache/log4j/Logger.class") );
Also if you are using Java 7, have a look at jHades, it's a tool I made to help troubleshooting these type of problems.
In order to see what is going on, could you post the results of the classpath queries above, for which container is this happening, tomcat, jetty? It would be better to put the full stacktrace with all the caused by's in pastebin, just in case.
Ternjs is a new alternative for getting JS autocompletion. http://ternjs.net/
Sublime Plugin
The most well-maintained Tern plugin for Sublime Text is called 'tern_for_sublime'
There is also an older plugin called 'TernJS'. It is unmaintained and contains several performance related bugs, that cause Sublime Text to crash, so avoid that.
This is a good example of the maven-ear-plugin part.
You can also check the maven archetypes that are available as an example. If you just runt mvn archetype:generate you'll get a list of available archetypes. One of them is
maven-archetype-j2ee-simple
make sure settings.py has
USE_TZ = True
In your python file:
from django.utils import timezone
timezone.now() # use its value in model field
Decode it with the unicode-escape
codec:
>>> a="Hello\u2026"
>>> a.decode('unicode-escape')
u'Hello\u2026'
>>> print _
Hello…
This is because for a non-unicode string the \u2026
is not recognised but is instead treated as a literal series of characters (to put it more clearly, 'Hello\\u2026'
). You need to decode the escapes, and the unicode-escape
codec can do that for you.
Note that you can get unicode
to recognise it in the same way by specifying the codec argument:
>>> unicode(a, 'unicode-escape')
u'Hello\u2026'
But the a.decode()
way is nicer.
If the request could not be correctly parsed (including the request entity/body) the appropriate response is 400 Bad Request [1].
RFC 4918 states that 422 Unprocessable Entity is applicable when the request entity is syntactically well-formed, but semantically erroneous. So if the request entity is garbled (like a bad email format) use 400; but if it just doesn't make sense (like @example.com
) use 422.
If the issue is that, as stated in the question, user name/email already exists, you could use 409 Conflict [2] with a description of the conflict, and a hint about how to fix it (in this case, "pick a different user name/email"). However in the spec as written, 403 Forbidden [3] can also be used in this case, arguments about HTTP Authorization notwithstanding.
412 Precondition Failed [4] is used when a precondition request header (e.g. If-Match
) that was supplied by the client evaluates to false. That is, the client requested something and supplied preconditions, knowing full well that those preconditions might fail. 412 should never be sprung on the client out of the blue, and shouldn't be related to the request entity per se.
I made the following code so that even beginners can understand. Just copy the code and read comments. Note that message to be send is declared as a global variable which you can change just before sending the message. General changes can be done in Handler function.

I had a similar error on my side when I was using JDBC in Java code.
According to this website (the second awnser) it suggest that you are trying to execute the query with a missing parameter.
For instance :
exec SomeStoredProcedureThatReturnsASite( :L_kSite );
You are trying to execute the query without the last parameter.
Maybe in SQLPlus
it doesn't have the same requirements, so it might have been a luck that it worked there.
You have to set to element_blank()
in theme()
elements you need to remove
ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut))+
theme(axis.title.x=element_blank(),
axis.text.x=element_blank(),
axis.ticks.x=element_blank())
Set positioning to absolute. That will solve the problem immediately, but might cause some problems in layout later. You can always figure out a way around them ;)
Example:
position:absolute;
you can change the encryption of the password like this.
ALTER USER 'yourusername'@'localhost' IDENTIFIED WITH mysql_native_password BY 'youpassword';
The answer to this is simple and can be found on MSDN
Remember that a floating-point number can only approximate a decimal number, and that the precision of a floating-point number determines how accurately that number approximates a decimal number. By default, a Double value contains 15 decimal digits of precision, although a maximum of 17 digits is maintained internally.
In your example, the value of i is 6.89999999999999946709 which has the number 9 for all positions between the 3rd and the 16th digit (remember to count the integer part in the digits). When converting to string, the framework rounds the number to the 15th digit.
i = 6.89999999999999 946709
digit = 111111 111122
1 23456789012345 678901

mysqldump
utility can help you, basically with --tab
option it's a wrapped for SELECT INTO OUTFILE
statement.
Example:
mysqldump -u root -p --tab=/tmp world Country --fields-enclosed-by='"' --fields-terminated-by="," --lines-terminated-by="\n" --no-create-info
This will create csv formatted file /tmp/Country.txt
Let's dissect it. There are three parts:
cd
-- This is change directory command./d
-- This switch makes cd
change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0
. (%~d0
Changs active drive, cd %~p0
change the directory).%~dp0
-- This can be dissected further into three parts:
%0
-- This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.%~0
-- The ~
there strips double quotes ("
) around the expanded argument.%dp0
-- The d
and p
there are modifiers of the expansion. The d
forces addition of a drive letter and the p
adds full path.My problem is similar to yours. Here exist an error!
compile 'com.android.support:appcompat-v7:25.3.0'

Containers will already generally wrap their content nicely. It often doesn't work as well the other way around: children don't fill their ancestors nicely. So, set your width/height values on the inner-most element rather than the outer-most element, and let the outer elements wrap their contents.
.container {
background: blue;
padding: 10px;
}
img {
display: block;
max-height: 200px;
max-width: 200px;
}
Your code was compiled with Java 8.
Either compile your code with an older JDK (compliance level) or run it on a Java 8 JRE.
Hope this helps...
It appears the proper way to resolve this issue is to run
pip install --upgrade virtualenv
after you have upgraded python with Homebrew.
This should be a general procedure for any formula that installs something like python, which has it's own package management system. When you install brew install python
, you install python
and pip
and easy_install
and virtualenv
and so on. So, if those tools can be self-updated, it's best to try to do so before looking to Homebrew as the source of problems.
Er, it's not really a test if you don't add something to your path:

I got the error when uploading a React Native Expo bundle to Apple App Store Connect using Transporter. The problem was that I had transferred the app from my personal account to our company account but forgot to sign into our company account in Transporter.

This Works fine for me
var osvar = process.platform;
if (osvar == 'darwin') {
console.log("you are on a mac os");
}else if(osvar == 'win32'){
console.log("you are on a windows os")
}else{
console.log("unknown os")
}
Here's an approach using generators:
function* square(n) {
for (var i = 0; i < n; i++ ) yield i*i;
}
Then you can write
console.log(...square(7));
Another idea is:
[...Array(5)].map((_, i) => i*i)
Array(5)
creates an unfilled five-element array. That's how Array
works when given a single argument. We use the spread operator to create an array with five undefined elements. That we can then map. See http://ariya.ofilabs.com/2013/07/sequences-using-javascript-array.html.
Alternatively, we could write
Array.from(Array(5)).map((_, i) => i*i)
or, we could take advantage of the second argument to Array#from
to skip the map
and write
Array.from(Array(5), (_, i) => i*i)
A horrible hack which I saw recently, which I do not recommend you use, is
[...1e4+''].map((_, i) => i*i)
What's this "other information"? An IP address?
In PHP, you use $_SERVER['REMOTE_ADDR']
to get the IP address of the remote client, then you can use gethostbyaddr()
to try and conver that IP into a hostname - but not all IPs have a reverse mapping configured.
I recommend doing it with webpack (assumes you're using webpack).
Defining constants is as simple as setting the webpack config file:
var webpack = require('webpack');
module.exports = {
plugins: [
new webpack.DefinePlugin({
'APP_ENV': '"dev"',
'process.env': {
'NODE_ENV': '"development"'
}
})
],
};
This way you define them outside your source, and they will be available in all your files.
For swift 4.0 This will do the trick. It will disable the Cell in didSelectRowAtIndexPath method but keep the subviews clickable.
func tableView(_ tableView: UITableView, willSelectRowAt indexPath: IndexPath) -> IndexPath? {
if (indexPath.row == clickableIndex ) {
return indexPath
}else{
return nil
}
}
The following is from Adobe docs.
The media queries specification also provides the keyword only
, which is intended to hide media queries from older browsers. Like not
, the keyword must come at the beginning of the declaration. For example:
media="only screen and (min-width: 401px) and (max-width: 600px)"
Browsers that don't recognize media queries expect a comma-separated list of media types, and the specification says they should truncate each value immediately before the first nonalphanumeric character that isn't a hyphen. So, an old browser should interpret the preceding example as this:
media="only"
Because there is no such media type as only, the stylesheet is ignored. Similarly, an old browser should interpret
media="screen and (min-width: 401px) and (max-width: 600px)"
as
media="screen"
In other words, it should apply the style rules to all screen devices, even though it doesn't know what the media queries mean.
Unfortunately, IE 6–8 failed to implement the specification correctly.
Instead of applying the styles to all screen devices, it ignores the style sheet altogether.
In spite of this behavior, it's still recommended to prefix media queries with only if you want to hide the styles from other, less common browsers.
So, using
media="only screen and (min-width: 401px)"
and
media="screen and (min-width: 401px)"
will have the same effect in IE6-8: both will prevent those styles from being used. They will, however, still be downloaded.
Also, in browsers that support CSS3 media queries, both versions will load the styles if the viewport width is larger than 401px
and the media type is screen.
I'm not entirely sure which browsers that don't support CSS3 media queries would need the only
version
media="only screen and (min-width: 401px)"
as opposed to
media="screen and (min-width: 401px)"
to make sure it is not interpreted as
media="screen"
It would be a good test for someone with access to a device lab.
The TextWatcher
interface has 3 callbacks methods which are all called in the following order when a change occurred to the text:
beforeTextChanged(CharSequence s, int start, int count, int after)
s
parameter is the text before any change is applied.start
parameter is the position of the beginning of the changed part in the text.count
parameter is the length of the changed part in the s
sequence since the start
position.after
parameter is the length of the new sequence which will replace the part of the s
sequence from start
to start+count
.TextView
from this method (by using myTextView.setText(String newText)
).onTextChanged(CharSequence s, int start, int before, int count)`
beforeTextChanged
method but called after the text changes.s
parameter is the text after changes have been applied.start
parameter is the same as in the beforeTextChanged
method.count
parameter is the after
parameter in the beforeTextChanged method.before
parameter is the count
parameter in the beforeTextChanged method.TextView
from this method (by using myTextView.setText(String newText)
).afterTextChanged(Editable s)
TextView
from this method.TextView
, the TextWatcher
will be triggered again, starting an infinite loop. You should then add like a boolean _ignore
property which prevent the infinite loop.new TextWatcher() {
boolean _ignore = false; // indicates if the change was made by the TextWatcher itself.
@Override
public void afterTextChanged(Editable s) {
if (_ignore)
return;
_ignore = true; // prevent infinite loop
// Change your text here.
// myTextView.setText(myNewText);
_ignore = false; // release, so the TextWatcher start to listen again.
}
// Other methods...
}
TextViewListener
Personally, I made my custom text listener, which gives me the 4 parts in separate strings, which is, for me, much more intuitive to use.
/**
* Text view listener which splits the update text event in four parts:
* <ul>
* <li>The text placed <b>before</b> the updated part.</li>
* <li>The <b>old</b> text in the updated part.</li>
* <li>The <b>new</b> text in the updated part.</li>
* <li>The text placed <b>after</b> the updated part.</li>
* </ul>
* Created by Jeremy B.
*/

/**

*/
private String _before;
/**

String completeNewText = before + aNew + after;
// update TextView
startUpdates(); // to prevent infinite loop.
myEditText.setText(myNewText);
endUpdates();

}
Just for fun I thought I'd throw a forEach(f())
solution in too.
var a=[];
"14 2".split(" ").forEach(function(e){a.push(parseInt(e,10))});
// a = [14,2]
I leave you a utility function to inmutably update objects
/**
* Inmutable update object
* @param {Object} oldObject Object to update
* @param {Object} updatedValues Object with new values
* @return {Object} New Object with updated values
*/
export const updateObject = (oldObject, updatedValues) => {
return {
...oldObject,
...updatedValues
};
};
So you can use it like this
const MyComponent = props => {
const [orderForm, setOrderForm] = useState({
specialities: {
elementType: "select",
elementConfig: {
options: [],
label: "Specialities"
},
touched: false
}
});
// I want to update the options list, to fill a select element
// ---------- Update with fetched elements ---------- //
const updateSpecialitiesData = data => {
// Inmutably update elementConfig object. i.e label field is not modified
const updatedOptions = updateObject(
orderForm[formElementKey]["elementConfig"],
{
options: data
}
);
// Inmutably update the relevant element.
const updatedFormElement = updateObject(orderForm[formElementKey], {
touched: true,
elementConfig: updatedOptions
});
// Inmutably update the relevant element in the state.
const orderFormUpdated = updateObject(orderForm, {
[formElementKey]: updatedFormElement
});
setOrderForm(orderFormUpdated);
};
useEffect(() => {
// some code to fetch data
updateSpecialitiesData.current("specialities",fetchedData);
}, [updateSpecialitiesData]);
// More component code
}

Using Django's session framework should cover most scenarios, but Django also now provide direct cookie manipulation methods on the request and response objects (so you don't need a helper function).
Setting a cookie:
def view(request):
response = HttpResponse('blah')
response.set_cookie('cookie_name', 'cookie_value')
Retrieving a cookie:
def view(request):
value = request.COOKIES.get('cookie_name')
if value is None:
# Cookie is not set
# OR
try:
value = request.COOKIES['cookie_name']
except KeyError:
# Cookie is not set
You already get the next line in this line of your code:
String line = sc.nextLine();
To get the words of a line, I would recommend to use:
String[] words = line.split(" ");
&something
gives you the address of the std::vector
object, not the address of the data it holds. &something.begin()
gives you the address of the iterator returned by begin()
(as the compiler warns, this is not technically allowed because something.begin()
is an rvalue expression, so its address cannot be taken).
Assuming the container has at least one element in it, you need to get the address of the initial element of the container, which you can get via
&something[0]
or &something.front()
(the address of the element at index 0), or
&*something.begin()
(the address of the element pointed to by the iterator returned by begin()
).
In C++11, a new member function was added to std::vector
: data()
. This member function returns the address of the initial element in the container, just like &something.front()
. The advantage of this member function is that it is okay to call it even if the container is empty.
I had this same question and this is how I am doing it, from a KafkaConsumer, in Kotlin:
val messageCount = consumer.listTopics().entries.filter { it.key == topicName }
.map {
it.value.map { topicInfo -> TopicPartition(topicInfo.topic(), topicInfo.partition()) }
}.map { consumer.endOffsets(it).values.sum() - consumer.beginningOffsets(it).values.sum()}
.first()
Very rough code, as I just got this to work, but basically you want to subtract the topic's beginning offset from the ending offset and this will be the current message count for the topic.
You can't just rely on the end offset because of other configurations (cleanup policy, retention-ms, etc.) that may end up causing the deletion old messages from your topic. Offsets only "move" forward, so it is the beggining offset that will move forward closer to the end offset (or eventually to the same value, if the topic contains no message right now).
Basically the end offset represents the overall number of messages that went through that topic, and the difference between the two represent the number of messages that the topic contains right now.
To find the fastest way to read a file line by line you will have to do some benchmarking. I have done some small tests on my computer but you cannot expect that my results apply to your environment.
Using StreamReader.ReadLine
This is basically your method. For some reason you set the buffer size to the smallest possible value (128). Increasing this will in general increase performance. The default size is 1,024 and other good choices are 512 (the sector size in Windows) or 4,096 (the cluster size in NTFS). You will have to run a benchmark to determine an optimal buffer size. A bigger buffer is - if not faster - at least not slower than a smaller buffer.
const Int32 BufferSize = 128;
using (var fileStream = File.OpenRead(fileName))
using (var streamReader = new StreamReader(fileStream, Encoding.UTF8, true, BufferSize)) {
String line;
while ((line = streamReader.ReadLine()) != null)
// Process line
}
The FileStream
constructor allows you to specify FileOptions. For example, if you are reading a large file sequentially from beginning to end, you may benefit from FileOptions.SequentialScan
. Again, benchmarking is the best thing you can do.
Using File.ReadLines
This is very much like your own solution except that it is implemented using a StreamReader
with a fixed buffer size of 1,024. On my computer this results in slightly better performance compared to your code with the buffer size of 128. However, you can get the same performance increase by using a larger buffer size. This method is implemented using an iterator block and does not consume memory for all lines.
var lines = File.ReadLines(fileName);
foreach (var line in lines)
// Process line
Using File.ReadAllLines
This is very much like the previous method except that this method grows a list of strings used to create the returned array of lines so the memory requirements are higher. However, it returns String[]
and not an IEnumerable<String>
allowing you to randomly access the lines.
var lines = File.ReadAllLines(fileName);
for (var i = 0; i < lines.Length; i += 1) {
var line = lines[i];
// Process line
}
Using String.Split
This method is considerably slower, at least on big files (tested on a 511 KB file), probably due to how String.Split
is implemented. It also allocates an array for all the lines increasing the memory required compared to your solution.
using (var streamReader = File.OpenText(fileName)) {
var lines = streamReader.ReadToEnd().Split("\r\n".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
foreach (var line in lines)
// Process line
}
My suggestion is to use File.ReadLines
because it is clean and efficient. If you require special sharing options (for example you use FileShare.ReadWrite
), you can use your own code but you should increase the buffer size.
You won't need a library; if you are using a recent version of Java, have a look at String.format
:
String.format("Hello %s!", "world");
I find this easier to use...
static ArrayList<Individual> group[];
......
void initializeGroup(int size)
{
group=new ArrayList[size];
for(int i=0;i<size;i++)
{
group[i]=new ArrayList<Individual>();
}
In case it helps others, I got this error when the service the task was running at didn't have write permission to the executable location. It was attempting to write a log file there.
You had thead
in your selector, but there is no thead
in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr
class to the th
, not vice-versa (although your comment seems to contradict what you wrote up above).
$('tr th').each(function(index){ if($('tr td').eq(index).attr('class') != ''){ // get the class of the td var tdClass = $('tr td').eq(index).attr('class'); // add it to this th $(this).addClass(tdClass ); } });
In your regex you need to escape the dot "\."
or use it inside a character class "[.]"
, as it is a meta-character in regex, which matches any character.
Also, you need \w+
instead of \w
to match one or more word characters.
Now, if you want the test.this
content, then split
is not what you need. split
will split your string around the test.this
. For example:
>>> re.split(r"\b\w+\.\w+@", s)
['blah blah blah ', 'gmail.com blah blah']
You can use re.findall
:
>>> re.findall(r'\w+[.]\w+(?=@)', s) # look ahead
['test.this']
>>> re.findall(r'(\w+[.]\w+)@', s) # capture group
['test.this']
Chrome supports WebDatabase API (which is powered by sqlite), but looks like W3C stopped its development.
Sometimes, you only need this code.
httpClient.DefaultRequestHeaders.Add("token", token);
Try to use getAsJsonObject()
instead of a straight cast used in the accepted answer:
JsonObject o = new JsonParser().parse("{\"a\": \"A\"}").getAsJsonObject();
The new :is()
CSS pseudo-class can do it in one selector:
:is(h1, h2, h3, h4, h5, h6) {
color: red;
}
I had the same problem with Pool()
in Python 3.6.3.
Error received: TypeError: can't pickle _thread.RLock objects
Let's say we want to add some number num_to_add
to each element of some list num_list
in parallel. The code is schematically like this:
class DataGenerator:
def __init__(self, num_list, num_to_add)
self.num_list = num_list # e.g. [4,2,5,7]
self.num_to_add = num_to_add # e.g. 1
self.run()
def run(self):
new_num_list = Manager().list()
pool = Pool(processes=50)
results = [pool.apply_async(run_parallel, (num, new_num_list))
for num in num_list]
roots = [r.get() for r in results]
pool.close()
pool.terminate()
pool.join()
def run_parallel(self, num, shared_new_num_list):
new_num = num + self.num_to_add # uses class parameter
shared_new_num_list.append(new_num)
The problem here is that self
in function run_parallel()
can't be pickled as it is a class instance. Moving this parallelized function run_parallel()
out of the class helped. But it's not the best solution as this function probably needs to use class parameters like self.num_to_add
and then you have to pass it as an argument.
Solution:
def run_parallel(num, shared_new_num_list, to_add): # to_add is passed as an argument
new_num = num + to_add
shared_new_num_list.append(new_num)
class DataGenerator:
def __init__(self, num_list, num_to_add)
self.num_list = num_list # e.g. [4,2,5,7]
self.num_to_add = num_to_add # e.g. 1
self.run()
def run(self):
new_num_list = Manager().list()
pool = Pool(processes=50)
results = [pool.apply_async(run_parallel, (num, new_num_list, self.num_to_add)) # num_to_add is passed as an argument
for num in num_list]
roots = [r.get() for r in results]
pool.close()
pool.terminate()
pool.join()
Other suggestions above didn't help me.

I am developing an app to version 2.2, API version would in the 8th ... had the same error and the error told me it was to google maps API, all we did was change my ADV for my project API 2.2 and also for the API.
This worked for me and found the library API needed.
In case somebody was looking for this.
The resolution below also works on PHPSpreadsheet
, their new version of PHPExcel.
// assuming $spreadsheet is instance of PhpOffice\PhpSpreadsheet\Spreadsheet
// assuming $worksheet = $spreadsheet->getActiveSheet();
foreach(range('A',$worksheet->getHighestColumn()) as $column) {
$spreadsheet->getColumnDimension($column)->setAutoSize(true);
}
Note:
getHighestColumn()
can be replaced withgetHighestDataColumn()
or the last actual column.
What these methods do:
getHighestColumn($row = null)
- Get highest worksheet column.
getHighestDataColumn($row = null)
- Get highest worksheet column that contains data.
getHighestRow($column = null)
- Get highest worksheet row
getHighestDataRow($column = null)
- Get highest worksheet row that contains data.
You need to indicate the groupId, the artifactId and the version for your artifact:
mvn install:install-file \
-DgroupId=javax.transaction \
-DartifactId=jta \
-Dpackaging=jar \
-Dversion=1.0.1B \
-Dfile=jta-1.0.1B.jar \
-DgeneratePom=true
It depends on the property type that you are parsing.
If the json property is a number (e.g. 5) you can cast to Long directly, so you could do:
(long) jsonObj.get("id") // with id = 5, cast `5` to long
After getting the long,you could cast again to int, resulting in:
(int) (long) jsonObj.get("id")
If the json property is a number with quotes (e.g. "5"), is is considered a string, and you need to do something similar to Integer.parseInt() or Long.parseLong();
Integer.parseInt(jsonObj.get("id")) // with id = "5", convert "5" to Long
The only issue is, if you sometimes receive id's a string or as a number (you cant predict your client's format or it does it interchangeably), you might get an exception, especially if you use parseInt/Long on a null json object.
If not using Java Generics, the best way to deal with these runtime exceptions that I use is:
if(jsonObj.get("id") == null) {
// do something here
}
int id;
try{
id = Integer.parseInt(jsonObj.get("id").toString());
} catch(NumberFormatException e) {
// handle here
}
You could also remove that first if and add the exception to the catch. Hope this helps.
ok this is an old thread -
but I spent nearly two days and did not get anywhere
Here is what solved my problem
I had USB debugging enabled ( finding developer options itself was a pain - I think the 7 times tap from google is childish and just plain stupid - rant over )
However HTC syn manager , eclipse ADT and windows computer management were all unable to identify my device
My problem was my phone was set to ONLY USB Charge - this was the problem In 'USB Computer connection' >> Choose the option USB Storage Once you do this - PC will install drivers and your device will get detected by Eclipse as well as in 'Computer Management' under ''Android USB devices '
Now I still dont know a way to access ''USB Computer connection' but at that time I did get the option to change and t worked
For those ( like me earlier ) who dont know how to identify if 'Computer Management' shows their device look for 'Android USB devices ' If its present - then your device is being detected by your PC
Hope this helps some others

Here's a couple of suggestions:
Use date_range
for the index:
import datetime
import pandas as pd
import numpy as np
todays_date = datetime.datetime.now().date()
index = pd.date_range(todays_date-datetime.timedelta(10), periods=10, freq='D')
columns = ['A','B', 'C']
Note: we could create an empty DataFrame (with NaN
s) simply by writing:
df_ = pd.DataFrame(index=index, columns=columns)
df_ = df_.fillna(0) # with 0s rather than NaNs
To do these type of calculations for the data, use a numpy array:
data = np.array([np.arange(10)]*3).T
Hence we can create the DataFrame:
In [10]: df = pd.DataFrame(data, index=index, columns=columns)
In [11]: df
Out[11]:
A B C

Even though it's stated in many of the other answers here, the component should either:
implement shouldComponentUpdate
to render only when state or properties change
switch to extending a PureComponent, which already implements a shouldComponentUpdate
method internally for shallow comparisons.
Here's an example that uses shouldComponentUpdate
, which works only for this simple use case and demonstration purposes. When this is used, the component no longer re-renders itself on each click, and is rendered when first displayed, and after it's been clicked once.

If you want to pass in the value to use, you have to use the enum type you declared and directly use the supplied value:
public string CreateFile(string id, string name, string description,
/* --> */ SupportedPermissions supportedPermissions)
{
file = new File
{
Name = name,
Id = id,
Description = description,
SupportedPermissions = supportedPermissions // <---
};
return file.Id;
}
If you instead want to use a fixed value, you don't need any parameter at all. Instead, directly use the enum value. The syntax is similar to a static member of a class:
public string CreateFile(string id, string name, string description) // <---
{
file = new File
{
Name = name,
Id = id,
Description = description,
SupportedPermissions = SupportedPermissions.basic // <---
};
return file.Id;
}
For those who could not get DATEADD to work, try this instead: ( NOW( ) - INTERVAL 1 MONTH )
For makecert, your startInfo.FileName
should be the complete path of makecert (or just makecert.exe if it's in standard path) then the Arguments
would be -sk server -sky exchange -pe -n CN=localhost -ir LocalMachine -is Root -ic MyCA.cer -sr LocalMachine -ss My MyAdHocTestCert.cer
now I'm bit unfamiliar with how certificate store works, but perhaps you'll need to set startInfo.WorkingDirectory
if you're referring the .cer files outside the certificate store

Here is an example to run a webdev service in Docker. The image's name is morrisjobke/webdav. You can pull it from Docker Hub.
After you run these images, you can then access the WebDAV instance at http://localhost:8888/webdav
. Internally the folder /var/webdav
is used as the WebDAV root.
You can run this container in the following way:
$ docker run -d -e USERNAME=test -e PASSWORD=test -p 8888:80 morrisjobke/webdav

This will update all the rows in that columns if safe mode is not enabled.
UPDATE table SET columnB = columnA;
If safe mode is enabled then you will need to use a where clause. I use primary key as greater than 0 basically all will be updated
UPDATE table SET columnB = columnA where table.column>0;
You don't escape quotes in regular expressions

To run org.apache.http.legacy perfectely in Android 9.0 Pie create an xml file res/xml/network_security_config.xml
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true">
<trust-anchors>
<certificates src="system" />

</base-config>
</network-security-config>
And add 2 tags tag in your AndroidManifest.xml
android:networkSecurityConfig="@xml/network_security_config" android:name="org.apache.http.legacy"
<?xml version="1.0" encoding="utf-8"?>
<manifest......>
<application android:networkSecurityConfig="@xml/network_security_config">

If you are using IntelliJ IDEA or Android Studio:
Go to Settings > Editor > General >Auto Import and check the Optimize imports on the fly checkbox.
I have the following code that scales the entire page through CSS properties. The important thing is to set body.style.width to the inverse of the zoom to avoid horizontal scrolling. You must also set transform-origin to top left to keep the top left of the document at the top left of the window.
var zoom = 1;
var width = 100;
function bigger() {
zoom = zoom + 0.1;
width = 100 / zoom;
document.body.style.transformOrigin = "left top";
document.body.style.transform = "scale(" + zoom + ")";
document.body.style.width = width + "%";
}
function smaller() {
zoom = zoom - 0.1;
width = 100 / zoom;
document.body.style.transformOrigin = "left top";
document.body.style.transform = "scale(" + zoom + ")";
document.body.style.width = width + "%";
}
I think your code is right. If you run the following code it converts the string '60' which is treated as varchar and it returns integer 60, if there is integer containing string in second it works.
select CONVERT(bigint,'60') as seconds
and it returns

HTTPS handshake to [blah] (for #136) failed. System.IO.IOException Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host
and
ReadResponse() failed: The server did not return a complete response for this request. Server returned 0 bytes.
The problem turned out to be that the SSL Server Certificate got missed and wasn't installed on a couple servers.
I'm assuming you want all three of those as part of the selection criteria. You'll need a few statements in your where but they will be similar to the link your question contained.
SELECT *
FROM MyTable
WHERE [dateColumn] > '3/1/2009' AND [dateColumn] <= DATEADD(day,1,'3/31/2009')
--make it inclusive for a datetime type
AND DATEPART(hh,[dateColumn]) >= 6 AND DATEPART(hh,[dateColumn]) <= 22
-- gets the hour of the day from the datetime
AND DATEPART(dw,[dateColumn]) >= 3 AND DATEPART(dw,[dateColumn]) <= 5
-- gets the day of the week from the datetime
Hope this helps.
To answer your first question, Microsoft does ship a DataContractJsonSerializer: see msdn How to: Serialize and Deserialize JSON Data
Definitely late to the party; anyway, for those interested, picking up on Lan's mention of HTML5 canvas, you can use gRaphaël Charting which has a MIT License (instead of HighCharts dual license). It's not Bootstrap-specific either, so it's more of a general suggestion.
I have to admit that HighCharts demos seem very pretty, and I have to warn that gRaphaël is quite hard to understand before becoming proficient with it. Anyway you can easily add nice features to your gRaphaël charts (say, tooltips or zooming effects), so it may be worth the effort.
I'm using the change-case extension and it works fine. I defined the shortcuts:
{
"key": "ctrl+shift+u",
"command": "extension.changeCase.upper",
"when": "editorTextFocus"
},
{
"key": "ctrl+u",
"command": "extension.changeCase.lower",
"when": "editorTextFocus"
},
Try this instead:
First, fix the line ending problem: (Notepad++ doesn't allow multi-line regular expressions)
Search [Extended Mode]: \r\n>
(Or your own system's line endings)
Replace: >
then
Search [Regex Mode]: <option[^>]+value="([^"]+)"[^>]*>.*
(if you want all occurences of value
rather than just the options, simple remove the leading option
)
Replace: \1
Explanation of the second regular expression:
<option[^>]+ Find a < followed by "option" followed by
at least one character which is not a >
value=" Find the string value="
([^"]+) Find one or more characters which are not a " and save them
to group \1
"[^>]*>.* Find a " followed by zero or more non-'>' characters
followed by a > followed by zero or more characters.
Yes, it's parsing HTML with a regex -- these warnings apply -- check the output carefully.
var str = 'test343',
isNumeric = /^[-+]?(\d+|\d+\.\d*|\d*\.\d+)$/;
isNumeric.test(str);
I just use something like this:
.c-dialogbox {
--width: 56rem;
--height: 32rem;
position: fixed;
width: var(--width);
height: var(--height);
left: calc( ( 100% - var(--width) ) / 2 );
right: calc( ( 100% - var(--width) ) / 2 );
top: calc( ( 100% - var(--height) ) / 2 );
bottom: calc( ( 100% - var(--height) ) / 2 );
}
It centers the dialog box both horizontally and vertically for me, and I can use different width and height to fit different screen resolutions to make it responsive, with media queries.
Not an option if you still need to provide support for browsers where CSS custom properties or calc()
are not supported (check on caniuse.)
Below mechanism helps in redirecting multiple lines to file. Keep complete string under "
so that we can redirect values of the variable.
#!/bin/bash
kernel="2.6.39"
echo "line 1, ${kernel}
line 2," > a.txt
echo 'line 2, ${kernel}
line 2,' > b.txt
Content of a.txt
is
line 1, 2.6.39
line 2,
Content of b.txt
is
line 2, ${kernel}
line 2,
I wanted the new application start up after the old one shuts down.
Using process.WaitForExit() to wait for your own process to shutdown makes no sense. It will always time out.
So, my approach is to use Application.Exit() then wait, but allow events to be processed, for a period of time. Then start a new application with the same arguments as the old.
static void restartApp() {
string commandLineArgs = getCommandLineArgs();
string exePath = Application.ExecutablePath;
try {
Application.Exit();
wait_allowingEvents( 1000 );
} catch( ArgumentException ex ) {
throw;
}
Process.Start( exePath, commandLineArgs );
}
static string getCommandLineArgs() {
Queue<string> args = new Queue<string>( Environment.GetCommandLineArgs() );
args.Dequeue(); // args[0] is always exe path/filename
return string.Join( " ", args.ToArray() );
}
static void wait_allowingEvents( int durationMS ) {
DateTime start = DateTime.Now;
do {
Application.DoEvents();
} while( start.Subtract( DateTime.Now ).TotalMilliseconds > durationMS );
}
You got a bunch of good answers, so I'll just throw out a suggestion. If you are going to be working on this project for more than 2 days, download eclipse or netbeans and build your project in there.
If you are not normally a java programmer, then the help it will give you will be invaluable.
It's not worth the 1/2 hour download/install if you are only spending 2 hours on it.
Both have hotkeys/menu items to "Fix imports", with this you should never have to worry about imports again.
Declare PtrSafe Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" _
(ByVal pCaller As Long, ByVal szURL As String, ByVal szFileName As String, _
ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long
Sub Example()
DownloadFile$ = "someFile.ext" 'here the name with extension
URL$ = "http://some.web.address/" & DownloadFile 'Here is the web address
LocalFilename$ = "C:\Some\Path" & DownloadFile !OR! CurrentProject.Path & "\" & DownloadFile 'here the drive and download directory
MsgBox "Download Status : " & URLDownloadToFile(0, URL, LocalFilename, 0, 0) = 0
End Sub
I found the above when looking for downloading from FTP with username and address in URL. Users supply information and then make the calls.
This was helpful because our organization has Kaspersky AV which blocks active
FTP.exe, but not web connections. We were unable to develop in house with ftp.exe and this was our solution. Hope this helps other looking for info!

Actually, there is a quite more flexible solution to this problem: writing a Web Component which will patch SVG as text in runtime. Also published in gist with a link to JSFiddle

You can use the custom TextView for whole app with custom font here is an example for that
public class MyTextView extends TextView {
Typeface normalTypeface = Typeface.createFromAsset(getContext().getAssets(), Constants.FONT_REGULAR);
Typeface boldTypeface = Typeface.createFromAsset(getContext().getAssets(), Constants.FONT_BOLD);
public MyTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public MyTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyTextView(Context context) {
super(context);
}
public void setTypeface(Typeface tf, int style) {
if (style == Typeface.BOLD) {
super.setTypeface(boldTypeface/*, -1*/);
} else {
super.setTypeface(normalTypeface/*, -1*/);
}
}
}
There's a tiny open-source component to sync/communicate between tabs/windows of the same origin (disclaimer - I'm one of the contributors!) based around localStorage
.
TabUtils.BroadcastMessageToAllTabs("eventName", eventDataString);
TabUtils.OnBroadcastMessage("eventName", function (eventDataString) {
DoSomething();
});
TabUtils.CallOnce("lockname", function () {
alert("I run only once across multiple tabs");
});

P.S. I took the liberty to recommend it here since most of the "lock/mutex/sync" components fail on websocket connections when events happen almost simultaneously
Here's a pretty decent example of how you can use the Bootstrap modal within an Angular2 app on GitHub.
The gist of it is that you can wrap the bootstrap html and jquery initialization in a component. I've created a reusable modal
component that allows you to trigger an open using a template variable.
<button type="button" class="btn btn-default" (click)="modal.open()">Open me!</button>
<modal #modal>
<modal-header [show-close]="true">
<h4 class="modal-title">I'm a modal!</h4>
</modal-header>
<modal-body>
Hello World!
</modal-body>
<modal-footer [show-default-buttons]="true"></modal-footer>
</modal>
You just need to install the npm package and register the modal module in your app module:
import { Ng2Bs3ModalModule } from 'ng2-bs3-modal/ng2-bs3-modal';
@NgModule({
imports: [Ng2Bs3ModalModule]
})
export class MyAppModule {}
You say "I am not using a forms to manipulate the data." But you are doing a POST. Therefore, you are, in fact, using a form, even if it's empty.
$.ajax's dataType tells jQuery what type the server will return, not what you are passing. POST can only pass a form. jQuery will convert data to key/value pairs and pass it as a query string. From the docs:
Data to be sent to the server. It is converted to a query string, if not already a string. It's appended to the url for GET-requests. See processData option to prevent this automatic processing. Object must be Key/Value pairs. If value is an Array, jQuery serializes multiple values with same key i.e. {foo:["bar1", "bar2"]} becomes '&foo=bar1&foo=bar2'.
Therefore:
This question seems to be ambiguous.
I'll try with my interpretation of the request.
def do_something(data)
puts "Found! #{data}"
end
a = { 'x' => 'test', 'y' => 'foo', 'z' => 'bar' }
a.each { |key,value| do_something(value) if key == 'x' }
This will loop over all the key,value pairs and do something only if the key is 'x'.
I think a quick way to change the options of a widget is using the configure
method.
In your case, it would look like this:
self.x.configure(state=NORMAL)
I liked James Jenkins reply with the ISNULL check, but I think he meant IFNULL. ISNULL does not have a second parameter like his syntax, but IFNULL has the second parameter after the expression being checked to substitute if a NULL is found.
Refer to here
write query with named parameter, use simple ListPreparedStatementSetter
with all parameters in sequence. Just add below snippet to convert the query in traditional form based to available parameters,
ParsedSql parsedSql = NamedParameterUtils.parseSqlStatement(namedSql);
List<Integer> parameters = new ArrayList<Integer>();
for (A a : paramBeans)
parameters.add(a.getId());
MapSqlParameterSource parameterSource = new MapSqlParameterSource();
parameterSource.addValue("placeholder1", parameters);
// create SQL with ?'s
String sql = NamedParameterUtils.substituteNamedParameters(parsedSql, parameterSource);
return sql;
Referring to the answers above, I am only adding this to help clarify things. It is possible to use HttpClient from .Net 4.0, and you have to install the package from here
However, the text is very confusion and contradicts itself.
This package is not supported in Visual Studio 2010, and is only required for projects targeting .NET Framework 4.5, Windows 8, or Windows Phone 8.1 when consuming a library that uses this package.
But underneath it states that these are the supported platforms.
Supported Platforms:
.NET Framework 4
Windows 8
Windows Phone 8.1
Windows Phone Silverlight 7.5
Silverlight 4
Portable Class Libraries
Ignore what it ways about targeting .Net 4.5. This is wrong. The package is all about using HttpClient in .Net 4.0. However, you may need to use VS2012 or higher. Not sure if it works in VS2010, but that may be worth testing.
Spring dependency inject help you to remove coupling from your classes. Instead of creating object like this:
UserService userService = new UserServiceImpl();
You will be using this after introducing DI:
@Autowired
private UserService userService;
For achieving this you need to create a bean of your service in your ServiceConfiguration
file. After that you need to import that ServiceConfiguration
class to your WebApplicationConfiguration
class so that you can autowire that bean into your Controller like this:
public class AccController {
@Autowired
private UserService userService;
}
You can find a java configuration based POC here example.
I got the same error message on GraphQL mutation input object then I found the problem, Actually in my case mutation expecting an object array as input but I'm trying to insert a single object as input. For example:
First try
const mutationName = await apolloClient.mutate<insert_mutation, insert_mutationVariables>({
mutation: MUTATION,
variables: {
objects: {id: 1, name: "John Doe"},
},
});
Corrected mutation call as an array
const mutationName = await apolloClient.mutate<insert_mutation, insert_mutationVariables>({
mutation: MUTATION,
variables: {
objects: [{id: 1, name: "John Doe"}],
},
});
Sometimes simple mistakes like this can cause the problems. Hope this'll help someone.
This tutorial:
http://techdroid.kbeanie.com/2010/02/sign-your-android-applications-for.html
was very helpful for me the first time I had to create a keystore. It is simple but the instructions on developer.android.com are a little too brief.
The part I was unsure about was where to save and what name to give the keystore file.
I seems it doesn't matter where you put it just be sure to keep it safe and keep a number of backups. I just put it in my app directory
Name the file "something.keystore" where something can be whatever you want. I used app_name.keystore, where app_name was the name of my app.
The next part was what to name the alias. Again it doesn't seem to matter so again I just used the app_name again. Keep the passwords the same as you used before. Fill out the rest of the fields and you are done.
This is 2 step process
If you want to push your branch code to remote repo then do
Perl one-liner:
perl -F'/[\/=]/' -lane 'print "$F[2]\t$F[4]\t$F[7]"' file
These command-line options are used:
-n
loop around every line of the input file, put the line in the $_
variable, do not automatically print every line
-l
removes newlines before processing, and adds them back in afterwards
-a
autosplit mode – perl will automatically split input lines into the @F
array. Defaults to splitting on whitespace
-F
autosplit modifier, in this example splits on either /
or =
-e
execute the perl code
Perl is closely related to awk, however, the @F
autosplit array starts at index $F[0]
while awk fields start with $1.

I had the same error which was coming and dont need to worry about this error, just restart the server and restart the SQL services. This issue comes when there is low disk space issue and system will go into hung state and then the sql services will stop automatically.
In most of the companies they required a common functionality for multiple dropdownlist for all the pages. Just call the functions or pass your (DropDownID,JsonData,KeyValue,textValue)
<script>
$(document).ready(function(){
GetData('DLState',data,'stateid','statename');
});
var data = [{"stateid" : "1","statename" : "Mumbai"},
{"stateid" : "2","statename" : "Panjab"},
{"stateid" : "3","statename" : "Pune"},
{"stateid" : "4","statename" : "Nagpur"},
{"stateid" : "5","statename" : "kanpur"}];
var Did=document.getElementById("DLState");
function GetData(Did,data,valkey,textkey){
var str= "";
for (var i = 0; i <data.length ; i++){
console.log(data);
str+= "<option value='" + data[i][valkey] + "'>" + data[i][textkey] + "</option>";
}
$("#"+Did).append(str);
}; </script>

Here is a generic and relatively fast solution that outputs integers from 1 to @n
. It works with any positive integer of @n
(very large numbers will cause arithmetic overflow) without needing to add or remove table joins. It doesn't require the use of system tables nor do you to change max recursions.
declare @n int = 10000
;with d as (select * from (values (0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) x (d)),
n as (
select d x from d where d > 0 and d <= @n
union all
select x * 10 + d from n, d where x * 10 + d <= @n
)
select x from n
You can add an order by
clause to sort the numbers.
It depends on the browser (although the latest version of all browsers should max out at 2147483638), as does the browser's reaction when the maximum is exceeded.
You should follow 2 steps:
This step can be followed by running the cmd in the specific folder location where there will be .war
file. This step helpful as Jenkins needs some disk space to perform builds and keep archives.
set JENKINS_HOME=c:\folder\Jenkins
This step will be helpful to change the port number, and works can be performed accordingly.
java -jar jenkins.war --httpPort=8585
I came here to learn how to create a function pointer (not a method pointer) from a method but none of the answers here provide a solution. Here is what I came up with:
template <class T> struct MethodHelper;
template <class C, class Ret, class... Args> struct MethodHelper<Ret (C::*)(Args...)> {
using T = Ret (C::*)(Args...);
template <T m> static Ret call(C* object, Args... args) {
return (object->*m)(args...);
}
};
#define METHOD_FP(m) MethodHelper<decltype(m)>::call<m>
So for your example you would now do:
Dog dog;
using BarkFunction = void (*)(Dog*);
BarkFunction bark = METHOD_FP(&Dog::bark);
(*bark)(&dog); // or simply bark(&dog)
Edit:
Using C++17, there is an even better solution:
template <auto m> struct MethodHelper;
template <class C, class Ret, class... Args, Ret (C::*m)(Args...)> struct MethodHelper<m> {
static Ret call(C* object, Args... args) {
return (object->*m)(args...);
}
};
which can be used directly without the macro:
Dog dog;
using BarkFunction = void (*)(Dog*);
BarkFunction bark = MethodHelper<&Dog::bark>::call;
(*bark)(&dog); // or simply bark(&dog)
For methods with modifiers like const
you might need some more specializations like:
template <class C, class Ret, class... Args, Ret (C::*m)(Args...) const> struct MethodHelper<m> {
static Ret call(const C* object, Args... args) {
return (object->*m)(args...);
}
};
var __ = function(){
this.context = [];
var self = this;
this.selector = function( _elem, _sel ){
return _elem.querySelectorAll( _sel );
}
this.on = function( _event, _element, _function ){
this.context = self.selector( document, _element );
document.addEventListener( _event, function(e){
var elem = e.target;
while ( elem != null ) {
if( "#"+elem.id == _element || self.isClass( elem, _element ) || self.elemEqal( elem ) ){
_function( e, elem );
}
elem = elem.parentElement;
}
}, false );
};
this.isClass = function( _elem, _class ){
var names = _elem.className.trim().split(" ");
for( this.it = 0; this.it < names.length; this.it++ ){
names[this.it] = "."+names[this.it];
}
return names.indexOf( _class ) != -1 ? true : false;
};
this.elemEqal = function( _elem ){
var flg = false;
for( this.it = 0; this.it < this.context.length; this.it++ ){
if( this.context[this.it] === _elem && !flg ){
flg = true;
}
}
return flg;
};
}
function _( _sel_string ){
var new_selc = new __( _sel_string );
return new_selc;
}
Now you can register event like,
_( document ).on( "click", "#brnPrepend", function( _event, _element ){
console.log( _event );
console.log( _element );
// Todo
});
Browser Support
chrome - 4.0, Edge - 9.0, Firefox - 3.5 Safari - 3.2, Opera - 10.0 and above
More clear example with es6 destructing
class Form extends Component {
constructor(props) {
super(props);
this.state = {
login: null,
password: null,
email: null
}
}
onChange(e) {
this.setState({
[e.target.name]: e.target.value
})
}
onSubmit(e) {
e.preventDefault();
let login = this.state.login;
let password = this.state.password;
// etc
}
render() {
return (
<form onSubmit={this.onSubmit.bind(this)}>
<input type="text" name="login" onChange={this.onChange.bind(this)} />
<input type="password" name="password" onChange={this.onChange.bind(this)} />
<input type="email" name="email" onChange={this.onChange.bind(this)} />
<button type="submit">Sign Up</button>
</form>
);
}
}
You can't declare an extern
local method inside of a method, or any other method with an attribute. Move your DLL import into the class:
using System.Runtime.InteropServices;
public class WindowHandling
{
[DllImport("User32.dll")]
public static extern int SetForegroundWindow(IntPtr point);
public void ActivateTargetApplication(string processName, List<string> barcodesList)
{
Process p = Process.Start("notepad++.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
IntPtr processFoundWindow = p.MainWindowHandle;
}
}
Sometimes it happens because of the version change like store 2012 db on 2008, so how to check it?
RESTORE VERIFYONLY FROM DISK = N'd:\yourbackup.bak'
if it gives error like:
Msg 3241, Level 16, State 13, Line 2 The media family on device 'd:\alibaba.bak' is incorrectly formed. SQL Server cannot process this media family. Msg 3013, Level 16, State 1, Line 2 VERIFY DATABASE is terminating abnormally.
Check it further:
RESTORE HEADERONLY FROM DISK = N'd:\yourbackup.bak'
BackupName is "* INCOMPLETE *", Position is "1", other fields are "NULL".
Means either your backup is corrupt or taken from newer version.
I had to send my context through a constructor on a custom adapter displayed in a fragment and had this issue with getApplicationContext(). I solved it with:
this.getActivity().getWindow().getContext()
in the fragments' onCreate
callback.
The var keyword in Javascript is there for a purpose.
If you declare a variable without the var keyword, like this:
myVar = 100;
It becomes a global variable that can be accessed from any part of your script. If you did not do it intentionally or are not aware of it, it can cause you pain if you re-use the variable name at another place in your javascript.
If you declare the variable with the var keyword, like this:
var myVar = 100;
It is local to the scope ({] - braces, function, file, depending on where you placed it).
This a safer way to treat variables. So unless you are doing it on purpose try to declare variable with the var keyword and not without.
this worked for me..
$sql = "desc MyTableName";
$result = @mysql_query($sql);
while($row = @mysql_fetch_array($result)){
echo $row[0]."<br>";
}
Try this, it's pure Ruby so there's no need to add any peripheral frameworks
if @players.include?(p.name) == false do
...
end
I was struggling with a similar logic for a few days, and after checking several forums and Q&A boards to little avail it turns out the solution was actually pretty simple.
I think you can try add parameter axis=1
to concat
, because output of df.iloc[0,:]
and df.iloc[-1,:]
are Series
and transpose by T
:
print df.iloc[0,:]
a 1
b a
Name: 0, dtype: object
print df.iloc[-1,:]
a 4
b d
Name: 3, dtype: object
print pd.concat([df.iloc[0,:], df.iloc[-1,:]], axis=1)
0 3
a 1 4
b a d
print pd.concat([df.iloc[0,:], df.iloc[-1,:]], axis=1).T
a b
0 1 a
3 4 d
You need to tell npm that "tsc" exists as a local project package (via the "scripts" property in your package.json) and then run it via npm run tsc
. To do that (at least on Mac) I had to add the path for the actual compiler within the package, like this
{
"name": "foo"
"scripts": {
"tsc": "./node_modules/typescript/bin/tsc"
},
"dependencies": {
"typescript": "^2.3.3",
"typings": "^2.1.1"
}
}
After that you can run any TypeScript command like npm run tsc -- --init
(the arguments come after the first --
).
try this,
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_sample, menu);
super.onCreateOptionsMenu(menu,inflater);
}
Finally, in onCreateView
method, add this line to make the options appear in your Toolbar
setHasOptionsMenu(true);
You do not need to use ORDER BY
in inner query after WHERE
clause because you have already used it in ROW_NUMBER() OVER (ORDER BY VRDATE DESC)
.
SELECT
*
FROM (
SELECT
Stockmain.VRNOA,
item.description as item_description,
party.name as party_name,
stockmain.vrdate,
stockdetail.qty,
stockdetail.rate,
stockdetail.amount,
ROW_NUMBER() OVER (ORDER BY VRDATE DESC) AS RowNum --< ORDER BY
FROM StockMain
INNER JOIN StockDetail
ON StockMain.stid = StockDetail.stid
INNER JOIN party
ON party.party_id = stockmain.party_id
INNER JOIN item
ON item.item_id = stockdetail.item_id
WHERE stockmain.etype='purchase'
) AS MyDerivedTable
WHERE

I wanted to install SQL server 2014 and same story happened. I had installed both VS2010 and VS2015 before. I tried all solutions where provided nothing worked.At last If you have new versions of VS like VS2015 or VS2017, uninstall VS2010 (if you really don't need it ).
If you want to have VS2010 on your system, install SQL server first and then install VS2010.When SQL server is installing it uses an instance of VS2010, if you have installed VS2010 before and that is an old version this error happens.
Centering content has so many avenues that it can't really be explored in a single answer. If you would like to explore them, CSS Zen Garden is an enjoyable-if-old resource exploring the many, many ways to layout content in a way even old browsers will tolerate.
The correct way, if you don't have any mitigating requirements, is to just apply margin: auto
to the sides, and a width
. If your page has no content that needs to go outside those margins, just apply it to the body:
body {
padding: 0;
margin: 15px auto;
width: 500px;
}
https://jsfiddle.net/b9chris/62wgq8nk/
So here we've got a 500px wide set of content centered at all* sizes. The padding 0 is to deal with some browsers that like to apply some default padding and throw us off a bit. In the example I do wrap the content in an article
tag to be nice to Screen Readers, Pocket, etc so for example the blind can jump past the nav you likely have (which should be in nav
) and straight to the content.
I say all* because below 500px this will mess up - we're not being Responsive. To get Responsive, you could just use Bootstrap etc, but building it yourself you use a Media Query like:
body {
padding: 0;
margin: 15px;
@media (min-width: 500px) {
margin: 15px auto;
width: 500px;
}
}
Note that this is SCSS/SASS syntax - if you're using plain CSS, it's inverted:
body {
padding: 0;
margin: 15px;
}
@media (min-width: 500px) {
body {
margin: 15px auto;
width: 500px;
}
}
https://jsfiddle.net/b9chris/62wgq8nk/6/
It's common however to want to center just one chunk of a page, so let's apply this to only the article tag in a final example.
body {
padding: 0;
margin: 0;
}
nav {
width: 100%;
box-sizing: border-box;
padding: 15px;
}
article {
margin: 15px;
@media (min-width: 500px) {
margin: 15px auto;
width: 500px;
}
}
https://jsfiddle.net/b9chris/62wgq8nk/17/
Note that this final example also uses CSS Flexbox in the nav, which is also one of the newer ways you could center things. So, that's fun.
But, there are special circumstances where you need to use other approaches to center content, and each of those is probably worth its own question (many of them already asked and answered here on this site).
Maybe it's because you have a line break in your PHP code. If you need line breaks in your alert window message, include it as an escaped syntax at the end of each line in your PHP code. I usually do it the following way:
$message = 'line 1.\\n';
$message .= 'line 2.';
Did you 'export' in your .bashrc?
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"/path/to/library"
Try this:
$Object = 'FirstPart SecondPart' | ConvertFrom-String -PropertyNames Val1, Val2
$Object.Val1
$Object.Val2
According to the Java 7 features list JSR-308 type annotations are deferred to Java 8. JSR-305 annotations are not even mentioned.
There is a bit of info on the state of JSR-305 in an appendix of the latest JSR-308 draft. This includes the observation that JSR-305 annotations seem to be abandoned. The JSR-305 page also shows it as "inactive".
In the mean time, the pragmatic answer is to use the annotation types that are supported by the most widely used tools ... and be prepared to change them if the situation changes.
In fact, JSR-308 does not define any annotation types/classes, and it looks like they think it is out of scope. (And they are right, given the existence of JSR-305).
However, if JSR-308 really looks like making it into Java 8, it wouldn't surprise me if interest in JSR-305 revived. AFAIK, the JSR-305 team hasn't formally abandoned their work. They have just been quiet for 2+ years.
It is interesting that Bill Pugh (the tech lead for JSR-305) is one of the guy behind FindBugs.

I don't mention basics like syntax highlighting as I expect these by default.
This is a just dry list reflecting your feedback and comments, I am not advocating any of these tools. I will keep updating this list as you keep posting your answers.
PS. Can you help me to add features of the above editors to the list (like auto-complete, debugging, etc.)?
We have a comprehensive wiki page for this question https://wiki.python.org/moin/IntegratedDevelopmentEnvironments
It's 2019 now :) For anyone wondering, here's where you'll find it:
C:\Program Files (x86)\Windows Kits\10\App Certification Kit

Edit: Still in the same place in 2020.
In your user settings add:

Delegates are extremely useful when wanting to declare a block of code that you want to pass around. For example when using a generic retry mechanism.
Pseudo:
function Retry(Delegate func, int numberOfTimes)
try
{
func.Invoke();
}
catch { if(numberOfTimes blabla) func.Invoke(); etc. etc. }
Or when you want to do late evaluation of code blocks, like a function where you have some Transform
action, and want to have a BeforeTransform
and an AfterTransform
action that you can evaluate within your Transform function, without having to know whether the BeginTransform
is filled, or what it has to transform.
And of course when creating event handlers. You don't want to evaluate the code now, but only when needed, so you register a delegate that can be invoked when the event occurs.
You can add your styles in the required page after the external style sheet so they'll cascade and overwrite the first set of rules.
<link rel="stylesheet" href="allpages.css">
<style>
.flex-control-thumbs li {
width: auto;
float: none;
}
</style>
On activity result is called before on resume. So move you login check to on resume and your second login can be blocked once the secomd activity has returned a positive result. On resume is called every time so there is not worries of it not being called the first time.
The answer seems to be to use the header more than once. That is, rather than sending
Access-Control-Allow-Origin: http://domain1.example, http://domain2.example, http://domain3.example
send
Access-Control-Allow-Origin: http://domain1.example
Access-Control-Allow-Origin: http://domain2.example
Access-Control-Allow-Origin: http://domain3.example
On Apache, you can do this in an httpd.conf
<VirtualHost>
section or .htaccess
file using mod_headers
and this syntax:
Header add Access-Control-Allow-Origin "http://domain1.example"
Header add Access-Control-Allow-Origin "http://domain2.example"
Header add Access-Control-Allow-Origin "http://domain3.example"
The trick is to use add
rather than append
as the first argument.
for(j = 0; j<=90; j = j+3)
{
}
j+3
will not assign the new value to j, add j=j+3
will assign the new value to j and the loop will move up by 3.
j++
is like saying j = j+1
, so in that case your assigning the new value to j just like the one above.
Simply put:
SELECT *
FROM TABLE_NAME
WHERE
dob > '1/21/2012'
Where 1/21/2012 is the date and you want all data, including that date.
SELECT *
FROM TABLE_NAME
WHERE
dob BETWEEN '1/21/2012' AND '2/22/2012'
Use a between if you're selecting time between two dates
In case if you are using node js, then this could be the possible solution
const express = require("express");
const app = express();
const server = app.listen(8080);
server.keepAliveTimeout = 61 * 1000;
Both certificates should exist prior to the connection. They're usually created by Certification Authorities (not necessarily the same). (There are alternative cases where verification can be done differently, but some verification will need to be made.)
The server certificate should be created by a CA that the client trusts (and following the naming conventions defined in RFC 6125).
The client certificate should be created by a CA that the server trusts.
It's up to each party to choose what it trusts.
There are online CA tools that will allow you to apply for a certificate within your browser and get it installed there once the CA has issued it. They need not be on the server that requests client-certificate authentication.
The certificate distribution and trust management is the role of the Public Key Infrastructure (PKI), implemented via the CAs. The SSL/TLS client and servers and then merely users of that PKI.
When the client connects to a server that requests client-certificate authentication, the server sends a list of CAs it's willing to accept as part of the client-certificate request. The client is then able to send its client certificate, if it wishes to and a suitable one is available.
The main advantages of client-certificate authentication are:

This example is from the MSDN page on ResourceManager.GetString():
// Create a resource manager to retrieve resources.
ResourceManager rm = new ResourceManager("items", Assembly.GetExecutingAssembly());
// Retrieve the value of the string resource named "welcome".
// The resource manager will retrieve the value of the
// localized resource using the caller's current culture setting.
String str = rm.GetString("welcome");

strtok can be very dangerous. It is not thread safe. Its intended use is to be called over and over in a loop, passing in the output from the previous call. The strtok function has an internal variable that stores the state of the strtok call. This state is not unique to each thread - it is global. If any other code uses strtok in another thread, you get problems. Not the kind of problems you want to track down either!
I'd recommend looking for a regex implementation, or using sscanf to pull apart the string.
Try this:
char strprint[256];
char text[256];
strcpy(text, "My string to test");
while ( sscanf( text, "%s %s", strprint, text) > 0 ) {
printf("token: %s\n", strprint);
}
Note: The 'text' string is destroyed as it's separated. This may not be the preferred behaviour =)
I had the same problem. Make sure your script didnt have
#!/bin/sh
at the top of your script. Instead, you should add
#!/bin/bash
Very simple in Swift. Just place the following into your App Delegate.
UserDefaults.standard.register(defaults: ["UserAgent" : "Custom Agent"])
If you want to append to the existing agent string then:
let userAgent = UIWebView().stringByEvaluatingJavaScript(from: "navigator.userAgent")! + " Custom Agent"
UserDefaults.standard.register(defaults: ["UserAgent" : userAgent])
Note: You may will need to uninstall and reinstall the App to avoid appending to the existing agent string.
if use JPA I recommend change to lowercase schema, table and column names, you can use next intructions for help you:
select
psat.schemaname,
psat.relname,
pa.attname,
psat.relid
from
pg_catalog.pg_stat_all_tables psat,
pg_catalog.pg_attribute pa
where
psat.relid = pa.attrelid
change schema name:
ALTER SCHEMA "XXXXX" RENAME TO xxxxx;
change table names:
ALTER TABLE xxxxx."AAAAA" RENAME TO aaaaa;
change column names:
ALTER TABLE xxxxx.aaaaa RENAME COLUMN "CCCCC" TO ccccc;
I believe your second activity is probably not linked to your main activity as a child activity. Check your AndroidManifest.xml
file and see if the <activity>
entry for your child activity includes a android:parentActivityName
attribute. It should look something like this:
<?xml ...?>
...
<activity
android:name=".MainActivity"
...>
</activity>
<activity
android:name=".ChildActivity"
android:parentActivityName=".MainActivity"
...>
</activity>

I created a procedure to search text in procedures/functions, tables, views, or jobs. The first parameter @search is the search criterion, @target the search target, i.e., procedures, tables, etc. If not specified, search all. @db is to specify the database to search, default to your current database. Here is my query in dynamic SQL.

Update: If you renamed a procedure, it only updates
sysobjects
but notsyscomments
, which keeps the old name and therefore that procedure will not be included in the search result unless you drop and recreate the procedure.
You can use Object.assign()
to merge them into a new object:
const response = {_x000D_
lat: -51.3303,_x000D_
lng: 0.39440_x000D_
}_x000D_
_x000D_
const item = {_x000D_
id: 'qwenhee-9763ae-lenfya',_x000D_
address: '14-22 Elder St, London, E1 6BT, UK'_x000D_
}_x000D_
_x000D_
const newItem = Object.assign({}, item, { location: response });_x000D_
_x000D_
console.log(newItem );
_x000D_
You can also use object spread, which is a Stage 4 proposal for ECMAScript:
const response = {_x000D_
lat: -51.3303,_x000D_
lng: 0.39440_x000D_
}_x000D_
_x000D_
const item = {_x000D_
id: 'qwenhee-9763ae-lenfya',_x000D_
address: '14-22 Elder St, London, E1 6BT, UK'_x000D_
}_x000D_
_x000D_
const newItem = { ...item, location: response }; // or { ...response } if you want to clone response as well_x000D_
_x000D_
console.log(newItem );
_x000D_
If you want to dump all collections, run this command:
mongodump -d {DB_NAME} -o /tmp
It will generate all collections data in json
and bson
extensions into /tmp/{DB_NAME}
directory
I was also having this issue of "You have mail" coming up every time I started Terminal.
What I discovered is this.
Something I'd installed (not entirely sure what, but possibly a script or something associated with an Alfred Workflow [at a guess]) made a change to the OS X system to start presenting Terminal bash notifications. Prior to that, it appears Wordpress had attempted to use the Local Mail system to send a message. The message bounced, due to it having an invalid Recipient address. The bounced message then ended up in the local system mail inbox. So Terminal (bash) was then notifying me that "You have mail".
You can access the mail by simply using the command
mail
This launches you into Mail, and it will right away show you a list of messages that are stored there. If you want to see the content of the first message, use
t
This will show you the content of the first message, in full. You'll need to scroll down through the message to view it all, by hitting the down-arrow
key.
If you want to jump to the end of the message, use the
spacebar
If you want to abort viewing the message, use
q
To view the next message in the queue use
n
... assuming there's more than one message.
NOTE: You need to use these commands at the mail ?
command prompt. They won't work whilst you are in the process of viewing a message. Hitting n
whilst viewing a message will just cause an error message related to regular expressions. So, if in the midst of viewing a message, hit q
to quit from that, or hit spacebar
to jump to the end of the message, and then at the ?
prompt, hit n
.
Viewing the content of the messages in this way may help you identify what attempted to send the message(s).
You can also view a specific message by just inputting its number at the ?
prompt. 3
, for instance, will show you the content of the third message (if there are that many in there).
Use the d
command (at the ?
command prompt )
d [message number]
To delete each message when you are done looking at them. For example, d 2
will delete message number 2. Or you can delete a list of messages, such as d 1 2 5 7
. Or you can delete a range of messages with (for example), d 3-10
.
You can find the message numbers in the list of messages mail shows you.
To delete all the messages, from the mail prompt (?
) use the command d *
.
As per a comment on this post, you will need to use q
to quit mail, which also saves any changes.
If you'd like to see the mail all in one output, use this command at the bash prompt (i.e. not from within mail, but from your regular command prompt):
cat /var/mail/<username>
And, if you wish to delete the emails all in one hit, use this command
sudo rm /var/mail/<username>
In my particular case, there were a number of messages. It looks like the one was a returned message that bounced. It was sent by a local Wordpress installation. It was a notification for when user "Admin" (me) changed its password. Two additional messages where there. Both seemed to be to the same incident.
What I don't know, and can't answer for you either, is WHY I only recently started seeing this mail notification each time I open Terminal. The mails were generated a couple of months ago, and yet I only noticed this "you have mail" appearing in the last few weeks. I suspect it's the result of something a workflow I installed in Alfred, and that workflow using Terminal bash to provide notifications... or something along those lines.
If you have no interest in determining the source of the messages, and just wish to get rid of them, it may be easier to do so without using the mail
command (which can be somewhat fiddly). As pointed out by a few other people, you can use this command instead:
sudo rm /var/mail/YOURUSERNAME
Besides the usages that JAiro mentioned, I like this one:
def getConnectionProps = {
( Config.getHost, Config.getPort, Config.getSommElse, Config.getSommElsePartTwo )
}
If someone needs all connection properties, he can do:
val ( host, port, sommEsle, someElsePartTwo ) = getConnectionProps
If you need just a host and a port, you can do:
val ( host, port, _, _ ) = getConnectionProps
Indeed this relies on the programmer's preferences. I personally use: numeric(15,4)
to conform to the Generally Accepted Accounting Principles (GAAP).
Keep in mind that unless you're writing your own data structure (e.g. linked list in C), it can depend dramatically on the implementation of data structures in your language/framework of choice. As an example, take a look at the benchmarks of Apple's CFArray over at Ridiculous Fish. In this case, the data type, a CFArray from Apple's CoreFoundation framework, actually changes data structures depending on how many objects are actually in the array - changing from linear time to constant time at around 30,000 objects.
This is actually one of the beautiful things about object-oriented programming - you don't need to know how it works, just that it works, and the 'how it works' can change depending on requirements.
Highlight "B1" and press F4. This will lock the cell.
Now you can drag it around and it will not change. The principle is simple. It adds a dollar sign before both coordinates. A dollar sign in front of a coordinate will lock it when you copy the formula around. You can have partially locked coordinates and fully locked coordinates.

I think the variable should be in the same block:
@{bool isUserConnected = string.IsNullOrEmpty(Model.CreatorFullName);
if (isUserConnected)
{ // meaning that the viewing user has not been saved
<div>
<div> click to join us </div>
<a id="login" href="javascript:void(0);" style="display: inline; ">join</a>
</div>
}
}
I don't know what things were like in the alpha, but I'm using beta 12 right now and this works fine. If you have an array of objects, create a select like this:
<select [(ngModel)]="simpleValue"> // value is a string or number
<option *ngFor="let obj of objArray" [value]="obj.value">{{obj.name}}</option>
</select>
If you want to match on the actual object, I'd do it like this:
<select [(ngModel)]="objValue"> // value is an object
<option *ngFor="let obj of objArray" [ngValue]="obj">{{obj.name}}</option>
</select>
It might mean the application is already installed for another user on your device. Users share applications. I don't know why they do but they do. So if one user updates an application is updated for the other user also. If you uninstall on one, it doesn't remove the app from the system on the other.
