Then he gets an OS dialog box (NOT generated by my program) with a caption saying "Can't run 16-bit Windows program" and the message saying "Cannot find file C:\DOCUME~1\[profile]\Local Settings\Temp\MYAPP.EXE".
So does this imply that GetShortPathName() succeeded in shortening the path to C:\DOCUME~1\[profile]\LOCALS~1\TEMP but that CreateProcess() has interpreted it as C:\DOCUME~1\[profile]\Local Settings\Temp instead? If, however, GetShortPathName() is failing, what does GetLastError() return?

I'm not entirely certain at this point, but I would have to wonder why CreateProcess() would take an 8.3 path and interpret it differently. There is currently no check for the value returned by GetShortPathName() (bad, I know), so I'll have to send the customer a special build to have it logged.
Graham's suggestion (that the NtfsDisable8dot3 registry setting might be disabled) is an interesting one, although if that was the case, I wouldn't expect the "Documents and Settings" part to get converted to DOCUME~1 (it was)...

Ok, if it is then you know the problem is not with GetShortPathName().
That still leaves an oddity with CreateProcess(). Have you ruled out AV software getting in the way?
Also, is MSDN article Q198429 of any help?

Actually, if GetShortPathName() failed, I wouldn't expect the output buffer to contain anything at all upon return, which isn't the case. I know that's an assumption, but still...
In any case, after further investigation, it looks like Graham's hint was right on the money. If I prevent the OS from creating 8.3 names, then any folder created *after* changing the registry value (and rebooting) will *not* get translated by GetShortPathName() (eg, "Local Settings" will be returned as just that, and not LOCALS~1).
Even with Explorer itself--if I copy a 16-bit EXE into a folder that doesn't have an 8.3 equivalent, and then double-click the EXE, Windows displays a message saying it can't find the file...
Next step is to ask the customer if he's messed with that registry value (predeployed disk image, SYSPREP tool, etc)...

The customer has the NtfsDisable8dot3 registry setting enabled?

I found a very useful guide to Windows programming from the ground up here. I followed it pretty closely, changing around a little bit by functionizing the initialization. The problem is when I run my app, it consumes all CPU power but I don't have it doing anything when the window pops up, just a window with a menu on top. Can someone go through that page and tell me if I or he missed something to create this problem? Thanks in advance.

Without seeing what code you actually put in place, it's kind of hard to say what might be wrong.

maybe you sould take a look at WaitMessage(VOID);

I had a suspicion something like that was there but I just couldn't find it. Thanks. Now to try to figure out the menus.

Try replacing:
<br />
while( true )<br />
{<br />
if( PeekMessage(...) )<br />
with
<br />
while( GetMessage(...) )<br />
GetMessage stops the program for running while waiting for a message, while PeekMessage doesn't, and you have a loop running at full speed.

Good call, I was wary of the `while(true)' loop.

Shouldn't that message loop be:
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(msg);
DispatchMessage(msg);
}

Yes, as long as this window message handling loop is not responsible for any dialog boxes.
Otherwise, and you need to know the dialog box's window handle:
while (GetMessage(&msg, NULL, 0, 0)){
if( !IsDialogMessage(hWndDialogBox, &msg) ){
TranslateMessage(&msg);
DispatchMessage (&msg);
}
}
You also might want to break if the message is WM_QUIT.
Now, the new and improved suggestions, from MSDN is:
BOOL bRet;
while( (bRet = GetMessage( &msg, NULL, 0, 0 )) != 0)
{
if (bRet == -1)
{
// handle the error and possibly exit
}
else
{
if( !IsDialogMessage(hWndDialogBox, &msg) ){
TranslateMessage(&msg);
DispatchMessage (&msg);
}
}
}

Hi all,
I was wondering if anyone could refer me to some c++ class that can be used to generate xml code from a dtd file. If not, then if someone knows of a class that can be used to validate a dtd file and/or tokenize it; not validate xml using dtd, but make sure that a dtd file is "valid".
Thanks in advance,

I'm not sure, but I'd lean towards the IXMLDOMDocument interface and its methods.

I looked into this class, but I am pretty sure it doesn't provide this functionality. I have not been able to find any class that will generate a basic valid xml document from a dtd file.

HI
I am getting error in executing a program ..It says that a dll file is not found.
How do I fix that?
Thanks

Supply the missing DLL, perhaps, or at least ensure that the DLL is located in one of the paths pointed to by the PATH environment variable. Without any more detailed information than what you've provided, I can't offer much more.

Thanks for reply
I don't understand how to ask...But let's see....
I don't know how to add that DLL file. I don't know why it is looking for that DLL file.
What do you mean when it says that
"Installing the file can fix the problem" ?
Thanks

Use Dependency Walker or Dumpbin to find out what DLLs are required by the application. Those DLLs, and possibly others, must exist on the target machine.

Isn't that self-explanatory? If the file existed and could be located by the OS, the problem would not exist.

I know that's self explanatory but I didn't know where from install the DLL file.

And you assumed someone here would, given that you did not provide the name of the application or the missing DLL?

The missing DLL is MSNHook.DLL
Tell me where to find this?

I believe, First you have to build the dll project come with you sample application.
