I am debugging in NetBeans IDE, where can I see assigned variables and their values?
While you're in the debugger go Window -> Debugger -> Variables
You can also use ALT+SHIFT+1 to bring up variable viewer.
Generally, the pane underneath the code has some tabs - and one of them will say 'Variables'. Click on that tab and you will see variables and their values. You need to be actually running a debug session before the variables tab is available.
For this to show all local variables you need to have the line:
xdebug.show_local_vars=1
in your xdebug.ini file. Don't forget to restart Apache if you add that line.
If you are not seeing all local variables then you may have hit the problem where your version of the module file (xdebug.so) has a bug. This is the case currently for Ubuntu 10.04.
To fix this you need to compile a newer version of the xdebug.so file. Follow the instructions at http://xdebug.org/wizard.php to get your new file which should replace your current xdebug.so file.
There exists another solution that is
Press Ctrl+F9 to display Evaluate Expression Panel/Tab
Enter variable name in Evaluate Expression Panel/Tab
Press Ctrl+Enter (or arrow icon at right of Evaluate Expression Panel/Tab
The variable's value is then displayed in Variables Panel just below (on my PC) Evaluate Expression Panel/Tab.
You can also use this solution to display EXPRESSION and not only VARIABLE !
Example: (String sSheetData is a String variable that contains a very big string)
sSheetData.substring(4000,4200);
StringTools.Right(sSheetData,100);
StringTools.Mid(sSheetData,4000,200);
This is also possible using New Watch callable using contextual menu.
But this is not as easy as using Immediate Windows on Microsoft Visual Studio :-)

I am trying to update an environmental variable in team city through a build's plan pop up (when you press run it pops up a window to set some var).
So far i the given value remain only for the specific build and then it discards.
Does anyone has any idea?
thank you
Yes, that is the intended functionality: when using that popup, you are only modifying the parameter for that one run. For a permanent change, you need to open the project settings instead and go to the Parameters page.
I could not find the live templates for Java! Who can tell me how to set? Thanks.
They're inside all the nodes that are not specific to another language than Java: iterations, output, plain, surround, etc.
As JB Nizet wrote there is not a special node for Java (but you can create one). If you want your own Live Template for Java created do the following.
Open Settings window (File -> Settings)
Click on Editor -> Live Templates
Choose Template Group in which you want to add your Live Template
(you can create your own Template Group if you wish)
Click on + icon and choose Live Template
Specify the Abbreviation, Description and Template text.
Do not forget to define the context (in your case Java)
Example
Here is an example of how to create your own TODO text
Open the Setting window with Live Templates editor (as specified above).
Click on + icon and select Template Group.
Name this group Java.
Click on + icon again and select Live Template.
Specify your Live Template and DEFINE CONTEXT.
In my case writing mtodo and pressing enter will result in:
// TODO myName
You can even use variables. Write in your Template text e.g. $DATE$ and $TIME$
// TODO myName $DATE$ $TIME$
Click on Edit variables button and assign to each variable (defined by dollar sign) and expression (predefined function).
Now mtodo will result in
// TODO myName 13.10.2015 15:39
Predefined functions could be found here. The example was created using IntelliJ IDEA 15 EAP.
For those of you who have taken Postfix completion for Live templates, it is worth mentioning they are different. from not-choosing pretty good answers from #JB Niznet and #vitfo, I guess that's the case for OP writer. The document, here, says:
Postfix code completion is similar to live templates, it transforms the current expression without selecting it. For example, you can type .if after an expression to invoke the corresponding postfix completion and wrap the expression with an if statement.
You can check out a list of postfix completions:
Open the Preferences window
Click on Editor -> General -> Postfix completion
By default, there is no JAVA group in this setting page.
However, these default settings distribute on each feature group. For example, iterations:

I'm Using resharper 6 nighty builds and VB.net. I've a big medium project with multiple files that don't follow the code style conventions of my company.
I've configured resharper with my own convenctions and It suggest to me the right name for each variable (perfect!).
But I can't find any automagic way to make the current name to be replaced with the suggested name.
Are there any way to do it? If not ... did you know ane fearure of coderush Xpress to achieve it?
Thanks.
If you've configured ReSharper with your naming conventions, then it should show a warning (blue squiggly underline) under any identifiers that don't comply. If you put the text cursor on one of those misnamed identifiers, you should see a pyramid icon appear near the left margin. Then you can press Alt+Enter (or click the pyramid icon) to drop down a quick-fix menu. There should be an option in the menu to "Rename to '_myField'". Usually it's the first item in the list, so you can just press Enter again to do the rename.
If you want to do this on everything in a source file, you can use the ReSharper > Inspect > Next Issue in File command (or its keyboard shortcut -- F12 in the IDEA keymap) to move the cursor to the next warning in the file. Then, if it's another name warning, you can use Alt+Enter, Enter again to fix it.
Unfortunately, there isn't a way to automatically fix every instance of a warning at once (though it's been requested; please feel free to vote for RSRP-126551 in their issue tracker).
I have a desktop application which reads files from a specified folder, then deposits the files to a folder in a third party document management system based on criteria that the user provides.
My question is:
is it possible to somehow provide different parameters to the code, depending on which shortcut of the application the user clicked on to start it up?
You can add command line parameters to a shortcut icon. Here's how you can do it in Windows:
On the Start Menu, navigate to Notepad.
Right click on Notepad and choose Send To > Desktop (Create Shortcut)
Right click on the newly-created desktop icon and choose Properties
Add your command line parameters to the Target text box.
For example, if you want notepad to open up the hosts file, this would be the content of Target property:
%SystemRoot%\system32\notepad.exe "C:\WINDOWS\system32\drivers\etc\hosts"
You can put pretty much anything into the Target property of a shortcut that you would put into a command line.
Yes.
The easiest way would be to have the shortcut pass those parameters in via the command line.
You could also use conditional compilation variables, and have 2 different .exes. You should be able to find samples of both approaches (command line and conditional compilation variable) in help.
I have a project in SSIS and I've added an Execute SQL Task which sends its result out to a variable. I wanted to confirm the value because I was worried that it would try to write it out as a resultset object rather than an actual integer (in this case I'm returning a COUNT).
My first thought was just to run it in debug mode and add the global variable to my Watch window. Unfortunately, when I right-click on the Watch window, the option to "Add Variable" is greyed out. What am I missing here?
I've gotten around confirming that my variable is set correctly, so I'm not interested in methods like putting a script in to do a MsgBox with the value or anything like that. For future reference I'd like to be able to watch variables in debug mode. If there are some kind of constraints on that then I'd like to know the what and why of it all if anyone knows.
The help is woefully inadequate on this one and every "tutorial" that I can find just says, "Add the variable to the Watch window and debug" as though there should never be a problem doing that.
Thanks for any insight!
I believe you can only add variables to the Watch window while the debugger is stopped on a breakpoint. If you set a breakpoint on a step, you should be able to enter variables into the Watch window when the breakpoint is hit. You can select the first empty row in the Watch window and enter the variable name (you may or may not get some Intellisense there, I can't remember how well that works.)
Drag the variable from Variables pane to Watch pane and voila!
I know this is very old and possibly talking about an older version of Visual studio and so this might not have been an option before but anyway, my way would be when at a breakpoint use the locals window to see all current variable values ( Debug >> Windows >> Locals )
Visual Studio 2013: Yes to both adding to the watch windows during debugging and dragging variables or typing them in without "user::". But before any of that would work I also needed to go to Tools > Options, then Debugging > General and had to scroll right down to the bottom of the right hand pane to be able to tick "Use Managed Compatibility Mode". Then I had to stop and restart debugging. Finally the above advice worked. Many thanks to the above and to this article: Visual Studio 2015 Debugging: Can't expand local variables?
