would there be any other functions I can use to achieve what I am trying to do?

overide the PreTranslateMessage function in the dialog class and check for the WM_LBUTTONDOWN message.

BOOL CMyDlg::PreTranslateMessage(MSG* pMsg)<br />
{<br />
    if( pMsg->message == WM_LBUTTONDOWN )<br />
    {<br />
        if( pMsg->hwnd != m_hWnd )// ignore the message if user has clicked on the dialog<br />

What about WM_MOUSEACTIVATE?

Within the WM_MOUSEACTIVATE handler, I guess you could call
GetDlgCtrlID(GetFocus()) to get the identity of the control.

Use the function - CheckTokenMembership(). You can find the code snippet here - http://msdn2.microsoft.com/en-us/library/aa376389(VS.85).aspx[^]. Just use it. Smile | :)

Thanks & Regards,

Opening of a file

15-Apr-08 20:40

I want check if a certain file is present at a certain location.
I am using the FileCreate function for this, but I have a problem in the creation of the filename parameter.

if I use the next line to create the filename everything works fine if the specified file is in the same directory as the source:
sprintf(FileName,"%s.txt",ProdBest[i]); //ProdBest is an array of strings containing the filename.

But I want a clear seperation between my Production files and the programm files, and store the Production files in a seperate directory (C:\ProdIn)
If I use the following line I always end up getting a INVALID_HANDLE_VALUE with GetLastError code = 2 (FILE_NOT_FOUND).
sprintf(FileName,"C:\ProdIn\%s.txt",ProdBest[i]);

So clearly I am making a mistake, but I don't know where or what

Can someone help me out?

Try using double back slash instead of single like this.
sprintf(FileName,"C:\\ProdIn\\%s.txt",ProdBest[i]);
