We think we may have now tracked the problem down.
Seems its not our bug 
http://support.microsoft.com/kb/813810[^]
Apparently the VC6 implementation of std::string is not that multiprocessor/thread safe 
[edit]
And yes, following one of the suggestions in the article fixed our problem. Now we need to decide which way we want to do the fix in the final product.

Well, I found PJ's site about a decade ago when I had a job I resigned from in 2000.
But I couldn't remember whether he had written something about the differences between the debug and release versions. That combined with the fact that I linked to Joe's site made me unsure about what the other Roger meant.

- Are you using a multi-threaded C run-time (I'm sure you are, but am asking for completeness
 ) - Are the STL objects being allocated in the same module (EXE/DLL) as they're destructed in? If not, you need to ensure you build all your different modules with a DLL version of the C run-time.
#2 has caused the same symptoms for me in the past as you're experiencing.

Yes, they all use the Multithreaded DLL for CRT etc. Double and triple checked.

I beleive they are all allocated/destructed in the same module, but they do all use the same Multithreaded DLL
At the moment were suspecting a hidden shared variable somewhere and combing the entire application for any file scope variables that should have been declared const which arn't.
1 suspect vector of objects has been found but that was before lunch and hasn't been fully investigated yet.

My gut instinct is buffer overruns. Get an eval copy of BoundsChecker and run your stuff through it.
(And if doing a lot of new/delete, consider going to fixed, preallocated buffers.)
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

We have an old copy of boundschecker 7 which I installed and tried to test the application with. Unfortunately since it was released there have enough changes to stop it from working.
It doesn't report any issues and fails to catch any kind of problem on my system. Trying to get hold of an eval version of BC 9 atm.

Its an odd one as if it was something like this I would expect it to happen when just a single calculation is run. It only happens when we have 2 running concurrently.

I want to display popup menu when clicking inside richedit control.
How to get the notification message when right click on it.

See here[^]
You need to google first, if you have "It's urgent please" mentioned in your question.

Try using Spy++ to find out. But I bet it's WM_CONTEXTMENU...
You might also have to subclass the edit control to get the message - there are many articles on codeproject that sublcass a poor-edit control, and some for rich-edit controls which may help.

Check out this article[^]. It explains how to show a context when you right click on a button. Follow the same for your richedit too.

hi all,
plz tell me how i can get the picture represeting the user account( which shows in logon screen and startmenu ) in windows xp.
Thanks & Regards

It seems that under C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures\ Windows XP stores an image with the user's login name that will be shown on the logon screen. So if your user's login name is "nitin3", then it will be C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures\nitin3.bmp. Don't know about other versions of windows. If you find out about any API to access this information, tell me.

I have installed the Platform SDK Windows Server 2003 Family, February 2003.
And now i want to use library files and include files of the installed sdk for my VC6.0 project.
So to do this, i changed the reference of include and library files in my VC6.0 project.
I went to Tools->Options then in Directories Tab and there, i changed the path
of the Include Files and Library Files.
And then i built my project.
But it is giving linker errors.
So how do i integrate this platform sdk with my project in VC6.0
Please help me.

run the following application under the startmenu.
"Startmenu->All Programs->Microsoft Platform SDK February 2003->Visual Studio Registration->Register PSDK Directories with Visual Studio"

I did this but still getting the same linker error.
fatal error LNK1112: module machine type IA64 conflicts with target machine X86.

It might help if you showed us what linker errors you were getting?

i am getting following linker error and also some command line warnings.
fatal error LNK1112: module machine type IA64 conflicts with target machine X86.
and command line warnings like:
cl: Command line warning D4007: '/Gm' requires '/Zi' option ignored.
cl: Command line warning D4002: ignoring unknown option '/ZI'.

You are (somehow) linking to the Itanium (IA64) libraries - have a look in your directory settings and get rid of any 64-bit directories!
sunnyram wrote: cl: Command line warning D4007: '/Gm' requires '/Zi' option ignored.
That says that you've somewhere got the /Gm option (Enable minimal rebuilds) set - you need to set /Zi (Enable debugging information) as well.
sunnyram wrote: cl: Command line warning D4002: ignoring unknown option '/ZI'.
/ZI = "enable Edit and Continue".
sunnyram wrote: cl: Command line warning D4002: ignoring unknown option '/GZ'.
/GZ = "Catch release-build errors in debug build".
All those options are in VC6 (as well as all VC++ compilers up to and including 2008)... what C++ compiler are you using?

Thanks again Stuart,
I am using VC++ 6.0 compiler.
from following web site ,
http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm
i downloaded the Windows Server 2003 PSDK and installed it.
Now i want to use the new libraries and include files of these installed sdk with
my VC++6.0 project.
so in VC==6.0 project, in Tools->Options and in Directories Tab, i changed Library files reference as
'C:\Program Files\Microsoft SDK\Lib'
and also made changes in Include Files section like
'C:\Program Files\Microsoft SDK\include'
'C:\Program Files\Microsoft SDK\include\mfc'
'C:\Program Files\Microsoft SDK\include\Win64\mfc'
'C:\Program Files\Microsoft SDK\include\Win64\crt'
'C:\Program Files\Microsoft SDK\include\Win64\atl'
and then with these changes i rebuilt my project and i am getting the linker error
as follows:
fatal error LNK1112: module machine type 'IA64' conflicts with target machine type 'X86'
so how do i fix this problem?
waiting for reply.

You don't want those Win64 header directories in your include directory list.
|
|
|
|
|
first Thanks for reply.
I removed the Win64 entries
'C:\Program Files\Microsoft SDK\include\Win64\mfc'
'C:\Program Files\Microsoft SDK\include\Win64\crt'
'C:\Program Files\Microsoft SDK\include\Win64\atl'
and now my Include File section contains the following things:
'C:\Program Files\Microsoft SDK\include'
'C:\Program Files\Microsoft SDK\include\mfc'
I rebuilt my VC++6.0 project
and now i am getting the following error:
fatal error RC1015: can not open include file 'afxres.h'

You've removed the standard Visual C++ include and library directories, haven't you...you still need those, but they need to be arranged so that the compiler will look at the 'Microsoft SDK' directories before the standard Visual C++ include directories.
I'm afraid I can't be more specific - I don't have access to VC++ 6 - I don't use anything older than VS 2003.

i followed, what you are saying.
now i gave the reference for old files also.
now i am getting another errors:
error C2371: 'size_t' : redefinition; different basic types
fatal error C1189: #error : afxv_cpu.h is only for MIPS R4000, DEC AXP, and IBM PowerPC builds.
How do i arrange the Executable, Include, Library and Source files section in
Directories tab of Tools->Option?
and what should be the order of the files?
Which files should i keep in the path for reference and which are not?
waiting for reply.
