are you sure this function is defined and declared and you have included the header file for this class.

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

Why obviously ? Seing your error and the fact that you are sure that you have a body for your function, then I would say that it is obvious that the file is not added to your project.
I am talking here about the cpp file, not the h file. How did you add this file to your project ?

Can you also post the function prototye (which is in the header file) and the function body (which is in the cpp file) ? Please use the code tag to format the code properly when posting.

Note that if you're building for Unicode then the first is an ANSI string and the second is Unicode and so the second in NOT the definition of the first.

The arguments of the function prototype do not match the arguments of the function definition if UNICODE is defined (in which case, LPCTSTR will resolve to a wchar string, and not a char string). So, replace the char in the function prototype by the same LPCTSTR and this should fix your problem.

The error message seems to be saying:
A function with the signature int __cdecl RecordExceptionInfo(struct _EXCEPTION_POINTERS *,char const *) is referenced in the file "ExceptionAttacher.???" from the function int __stdcall AfxWinMain(struct HINSTANCE__ *,struct HINSTANCE__ *,wchar_t *,int). Clearly the function int __cdecl RecordExceptionInfo(struct _EXCEPTION_POINTERS *,char const *) is declared or we would have a compiler error instead, but it's not defined or the file it's defined in is not included in the project because the linker can't find it.

PS: Why the function AfxWinMain defined in "ExceptionAttacher.xxx"? This function is part of the MFC framework and not meant to be user defined.

UNC path names....

Hi out there-

I have a UNC path \\192.168.0.100\share and would like to convert it to the network name. i.e. \\SERVER\share

WNetGetUniversalName doesn't like it and is reporting "The specified device name is invalid".

Is there an easy way to deal with this?

If you are simply wanting to convert an IP address to its host name, use gethostbyaddr().

I would like to copy file from local to remote machine using WMI in C++. Not quite sure how to do this.

According to MS doc, "Win32_Directory" can be a good candidate. Anybody got idea? Thanks in advance.

CListCtrl flickers on Vista

Hi,

My application uses a dialog with CListCtrl in report view, this list control gets updated heavily and frequently.
To stop flickering i have used SetRedraw(FALSE) before the update operation, like-

SetRedraw(FALSE);
//Update();
SetRedraw(TRUE);
Invalidate();

This trick is working fine with Win XP, but its unable to stop flickering on Vista.
I have also tried LockWindowUpdate(), but the problem remains.

Is there any known issue with using CListCtrl on Vista?
What else could be tried to stop Flickering?
