Hello everybody,
I'm experiencing a problem during debug with Microsoft Visual C++: wherever
I set a breakpoint (and even if I disable all breakpoints) the debugger
goes into disassembler mode, and it stops at the same line, returning a
dialog windows that says: "user breakpoint called from code at 0xXXXXXX".
The active module is NTDLL, the istruction is "int 3".
The odd thing is that if I open my code on another PC, it works fine, and so
does it if I launch it normally.
Can you help me? It's not very confortable working without the chance to use
the debug.
Thank you very much

Most likely it's a sign of heap corruption (hard-coded breakpoint in ntdll.dll,
raised by Debug Win32 heap when it detects a corruption; debug heap is enabled
only when the application is started under debugger)
(check also the output in Debug Output window, may be there is an explanation
of the problem). It should be possible to tell more if you could post the call stack
at the moment of the exception, with good symbols for system DLLs.
You can also try to enable Full PageHeap and test the application with it:
HKLM\Software\M icrosoft\Window s NT\CurrentVersi on\Image File Execution
Options\YourApp .exe
GlobalFlag = REG_DWORD 0x2000000
PageHeapFlags = REG_DWORD 0x3
(replace YourApp.exe with the real name of your executable)
With these settings set in Registry, run the application under debugger,
and wait for access violations or hard-coded breakpoints, then check
the call stack to find the reason of the problem. Better if the application
is linked with release version of CRT library.

It works!!!
Man, you earned a place of honour in my list of people to say thanks to in

I've been trying to solve that problem for 3 days, and it was driving me
crazy!
Thank you very much!

I'm trying to do some debugging of python extensions on Windows2K. MS
Visual Studio (.NET) says it can't find the debug version of the
python libraries. (The message is "python.exe does not contain any
debugging information".) I installed the binaries from the Windows
installer. How should I get the debug libraries? Or is that even
what I need? I'm kind of new to Windows, and Visual Studio in
particular, so maybe I'm way off base.

This is a feature that is really going on my nerves as I've been writing SOAP

When I'm debugging under Visual Sudio, IIS prefixes *all* streams that go to the
client with <!-- METADATA TYPE="ASP_DEBUG_INFO">. I'm using XMLHTTP in some
cases to receive data. Neither XMLHTTP v3 nor v4 seem to accept this as valid

Dear Great Experts,
I have a problem and need your help!
We have a Flat DLL built in C++ (CCC), and on top of it, we built another
DLL built in C# (SSS), which has .Net Assembly. CCC was imported into SSS.
Now we build applications using SSS as a reference, and we found some
problems exist in CCC.
From our applicatyion, We can Debug into SSS, but cannot go further into CCC.

Very often my VS2005 pro crashes after a debug.
I run ASP.NET debug, and all works well. Then I stop it, and all it's also
ok. Then, when I try to edit some code, it crashes and I need to kill it,
restart, reload project, etc.
it seems that the problem is with vb compiler integration, but I'm not sure.
Is this a known problem? Is there some solution? I cannot spend all my time
to reload VS and projects!

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
