In Visual Studio 2010 (Ultimate), is it possible to step through some code, and, if a variable is not correct (e.g. you want to get all records beginning with 'A' but there is none, so you want to try 'B' instead), is it possible to change the code while in debug mode, to do this (change variables while in debug mode)?
It is quite annoying to have to stop debugging, change a value, then debug again and see the result. It'd be much easier to do it all in debug mode, anyway.
Thanks
In the watch window just enter the statement you want executed. For example if you want to set the variable prefix to "B" then just type prefix = "B" and hit enter.
You may also change code while running, however there are a number of limitations to this feature. See Microsoft's Edit and Continue documentation for details: http://msdn.microsoft.com/en-us/library/bcew296c(v=vs.80).aspx.
In the Solution Explorer view, right-click on each reference of References, choose Properties. In the Properties view, sign False to the field of Embed Interop Types. This works for me.

If I hit F12 while my application runs under Visual Studio in debug mode, the WM_KEYDOWN never reaches my event loop, but it immediately triggers a breakpoint. Is it possible to disable this feature, or reassign it to another, less conflicting hotkey (e.g. CTRL+F12)? I figure the must be a registry key, but I can't find it...
Any help is greatly appreciated!
F12 is a reserved key for the debugger and its kernel-based https://msdn.microsoft.com/en-us/library/windows/desktop/ms646309.aspx
But you can change the registry entry
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug] UserDebuggerHotKey=dword:00000000
to something else like 0x13 (Pause)
got this from http://conemu.github.io/en/GlobalHotKeys.html
You can disable it from Tools->options->Keyboard
It's easy to reassign a value like that to whatever you want.
1) Go to Tools/Options and click on Keyboard (under environment). Then find the command associated with F12. Which one depends on which mapping scheme you use, so I can't tell you the one to find.)
Then change it to whatever you want.
Too bad I can't add comments...
When I type in F12 (for Press shortcut keys), I get Edit.GoToDefinition. If I remove that assignment and then try again, it shows how it is used with Page Inspector.
If you enter F12 and nothing shows, then you can assume that VS is not using F12 and something else is.
You can just try assigning F12 to something and see if that is called instead - then at least you will have some idea of if VS is controlling it or something external to VS is.
Remember that you could also have some application that has remapped F12 so that when you press it, your application is getting a signal that some other key or key combination has been pressed (happened to me once.)
So there I am, working on a Silverlight app, and between one build & run and the next, my debug output goes away. Where before I had dozens of lines of Debug.Writeline text, I now have only the module load and thread messages.
Yes, I'm in debug mode (vs. release mode).
Yes, my Output window says "Show output from: Debug".
Yes, when I right-click on the output window, every option is checked.
No, my Tools > options > debugging > general > "Redirect all output text to the immediate window" is not checked.
All I can figure (and it's a wild guess) is that for some reason, the VS debugger isn't attaching to the Silverlight app like it should.
What's weird is this has been happening for the last couple of days, out of the blue. And just as suddenly, all my debug messages start showing up again.
This is VERY frustrating.
EDIT: Of course, after returning to the project after the weekend, all Debug messages are back. No idea what was causing the issue, so I'm sure it will happen again.
Now the question is: should I leave this question open in case the problem arises again in the near future? What happens to an unawarded bounty?
I found the same problem and just by setting options → debugging → output window → Thread Exit Messages to true the output windows was begin to send the right messages !?
I had exactly the same issue. Out of the blue, debug.print stopped working. In my case, it used to go to the Immediate Window. Nothing there. Nothing in the Output window. I followed several suggestions to no avail until I found this one at http://www.experts-exchange.com/questions/26894732/Debug-Print-and-Debug-Write-no-longer-work-in-Visual-Studio-2010.html
There is a context menu in the Output/Debug pane. The "Program Output"
menu item was accidentally cleared.
Checked the item and it started working again (even though my output was the immediate window). What a relief...
Ensure that the DEBUG conditional compilation symbol is defined. The Debug class suggests that you "add the /d:DEBUG option to the compiler command line when you compile your code using a command line, or add #define DEBUG to the top of your file".
Did you create or modify an Application config? If yes: the initial created configuration by VS does contains the necessary wiring configurations to enable the debugging at all. Not sure what and if there are counterparts in Silverlight, but in WPF environments simply replacing the app.config will have the same effect as you expierience.
Check the Immediate Window. Check the options. There is a general setting that says "send Debug output to Immediate Window"
does someone might know how to search for a value in the locals
in visual studio 2010
or at least how can I expand all nodes, subnodes?
if you record a macro on activating locals tools window on VS2010 it will generated this line of code,
DTE.Windows.Item(EnvDTE.Constants.vsWindowKindLocals).Activate()
after debugging this code and inspecting DTE.Windows'ActiveWindow when the active window is local I unfortunately couldn't find anything helpful, but give it a try and you may find sth helpful
if you just need parameters of a method you can use MethodBase.GetCurrentMethod() in System.Reflection namespace and it will serve you well by this private memeber
((System.Reflection.RuntimeMethodInfo)(currentMethod)).m_parameters
that you can read programmatically by reflection or just quick watch it
There are several items here that would let you do what you need, but you'll likely have to tweak the code first:
http://www.codeproject.com/info/search.aspx?artkw=quickwatch&sbo=kw
Normally in Visual Studio, a watch cannot be evaluated unless the debugger is stopped at a breakpoint. Is there a trick or add-on to make Visual Studio evaluate a watch while the application is still running? For example, evaluate the watch every time execution passes a point in the code while it's still running and without changing the code to insert statements like Debug.WriteLine.
Not sure this is possible, but I thought I'd ask.
Yes, this is possible. Set a breakpoint at the location where you'd want to see the value. Right-click the breakpoint and choose "When Hit...". Tick "Print a message" and write an expression like { value }. The message is displayed in the Output window while your program runs.
I would do that using compiler directives.
#if DEBUG
Debug.WriteLine
#end if
No this is not possible to do. The evaluation feature in Visual Studio is a stack frame based mechanism. That is that every evaluation is done in the context of a given stack frame (as viewed through the stack window). When the program is running the set of stack frames is currently changing and hence it's not possible to do a stable evaluation.
Additionally there are other limitations in the CLR which prevent this from managed code. It's not possible for instance to execute a function unless the debugee process is in a very specific state.
I'm facing some troubles still while learning, so I guess it tends to get worse once I play with the big kids: warnings in dynamics aren't as precise and informative as VS's, there are no mouse-over tips, and exceptions to show me exactly where I've got it wrong.
I'm just too used to Visual Studio, it's intellisense and all the tools (dynamics is quite new when compared to Visual Studio)
More than solving simple code issues, i'd like to learn how to solve upcomming ones i might have in code not written by me or anything else i'd solve in 3 minutes in Visual Studio, as well as tips on how to survive in dynamics ax without all the Visual Studio tools.
The code editor in Dynamics AX has some intellisense, typing the name of a table or class variable followed by . or :: will give you a list of fields or methods available for that item. After you type the ( to start a method call, a tooltip pops up with parameters available on that method. When starting a new line, you can right click and List Tables, List Classes, List Types, etc. Most of those commands are also available via Shortcut Keys. Note that the intellisense only works if all the code in the method up to the location of your cursor is syntactically correct.
Make sure you have updated the cross reference in your development environment (Tools/Development tools/Cross-reference/Periodic/Update). With an updated cross reference, you can right click an any table, field, class, method, extended data type, or enum in the AOT and choose Add-Ins/Cross-reference/Used by to see where that item is used in the system.
You can also use Tools/Development tools/Code explorer to view the source to the application with all types, variables, and methods turned into hyperlinks so you can click to go right to the definition of that item.
Another useful tool is Application hierarchy tree, available either under Tools/Development tools, or on the right click Add-Ins menu. This will show you the class hierarchy, so you can easily see, for example, that SalesFormLetter derives from FormLetter, which derives from RunBaseBatch.
In the editor, you can highlight text and right click to Lookup Properties/Methods or Lookup Definition.
If you are trying to track down where in the system a particular infolog message is generated there are two strategies to use:
Set a breakpoint on the first line
of the method Info.add(). Then when
you run the code generating the
message, you will pop into the
debugger as soon as the infolog is
generated. You can then look at the stack
trace in the debugger to see where the code is that
generated the message.
Run Tools/Development
tools/Label/Label editor and search
for the text of the message. Select
the Label ID of the message, then
click Used by to see where that
message is used in the system.
There is also http://www.axassist.com/ which extends intellisense and many other extensions
What these guys said already is very interesting and helpful.
I'd like to add that within AX in real life you are probably working with multiple contexts. e.g. Code running in the client, code running in server, code running in p-code and in IL, COM integrations, Enterprise portal and so on.
My point is, if you want to figure something out through debugging, you must first understand where the code(s) you'd like to debug is running.
Knowing that is important because you might have to allow debugging or give permissions in multiple places.
Examples:
Windows AD debugging users (add yourself)
Allow debugging on client
Allow it on server
Disable IL if you want to use MorphX, otherwise attach the process in VS.
Allow World Wide Web Publishing Service to interact with desktop for EP.
One last thing, you are starting to work with ax right now, perhaps you will need to work with AX7(Dynamics 365 for Operations). This version of the system works only with visual studio. It is still x++, but you have a lot of the things VS provides you.
Take a look on EditorScripts Class,On AX Editor you can use it by right click and choose "Scripts". It is a kind of intellisense that can make by your self, for example: here is my in-line comment whenever I type "mycom" and press "tab"
public void template_flow_mycom(Editor editor)
{
xppSource xppSource = new xppSource(editor.columnNo());
int currentline = editor.currentLineNo();
int currentcol = editor.columnNo();
Source template = "//Partner comment "+date2str(today(),123,2,1,3,1,4, DateFlags::FormatAll )+" at "+time2str(timenow(), 1, 1)+" by MAX - Begin\n";
template+=strRep(" ", currentcol)+ "\n";
template+=strRep(" ", currentcol)+ "//Partner comment "+date2str(today(),123,2,1,3,1,4, DateFlags::FormatAll )+" at "+time2str(timenow(), 1, 1)+" by MAX - End\n";
editor.insertLines(template);
//move cursor to the empty line between the comments
editor.gotoLine(currentline+2);
editor.gotoCol(currentcol+4);
}
