There is some problem with the pdfshell.dll file. The moment you move your cursor over a file( or a pdf file not sure ) the file dialog disappears.

Unregister this dll using regsvr32(There is no use in doing this, since this could happen anywhere). Also if you use "new" for creating <code>CFileDialog this won't happen. This recently happened in one of our projects.

If you use VC debugger to see what all dll's are being loaded then you will see that the moment this dll is loaded the file dialog crashes. It's a shell extension dll for pdf files.

Hi Thanks for great help, but it is happening even if I use "new" to create CFileDialog.
What kind of application you got the same problem? Was that dialog based or SDI/MDI?
If you have some more information it will be helpful for fixing.

It was a dialog based application. Using "new" solved the issues.

Hi, thanks for reply. My application is little complicated, it is not just a dialog or MDI and I am still analyzing problem while fixing other bugs.
I will update if I find the solution.

Hi Nibu thomas,
Yes you are correct.
The problem is happening only when the File dialog shows the location "desktop" and the mouse cursor is on top of any file.
If I uncheck Folder Options --> View --> Show pop-up description
for folder and desktop items it is not happening. The problem seems related
to tool tip for files in desktop.
Thank you very much for your great help.
Best Regards,
Suman

Exactly.

If you unregister pdfshell.dll then it works fine. BTW I suggested newing of CFileDialog, does that help.

I have tried newing but that did not fix the problem. My system have Japanese OS. Can we unregister pdfshell.dll through program? If we do so, what will be the effect in end user system?
Thanks for your great help!!

End users might or might not have pdfshell. So disabling it on your machine is of no good. So you will have to find a workaround. I don't think it's due to Japaneese OS.

Hi all:

I just did not find description about when the MapViewOfFile is called, how's the file on disk is updated, It seems to be updated periodically by OS, beside to do it explicitly with FlushViewOfFile. But I'm not sure about it.

Hi all,

What function does one use again to get all the information about a file.
Date created, Date modified and so on.

Many Thanks

GetFileTime

Here is a sample from MSDN...

BOOL GetLastWriteTime(HANDLE hFile, LPSTR lpszString)
{
    FILETIME ftCreate, ftAccess, ftWrite, ftLocal;
    SYSTEMTIME stCreate;

    // Retrieve the file times for the file.
    if (!GetFileTime(hFile, &ftCreate, &ftAccess, &ftWrite))
        return FALSE;

    // Convert the last-write time to local time.
    if (!FileTimeToLocalFileTime(&ftWrite, &ftLocal))
        return FALSE;

    // Convert the local file time from UTC to system time.
    FileTimeToSystemTime(&ftLocal, &stCreate);

    // Build a string showing the date and time.
    wsprintf(lpszString, "%02d/%02d/%d  %02d:%02d",
        stCreate.wDay, stCreate.wMonth, stCreate.wYear,
        stCreate.wHour, stCreate.wMinute);

    return TRUE;
}
