Problems with the CFileDialog Class

[stream2000]

I've created a file dialog with multipleselect.
If I'm trying to increase m_ofn.nMaxFile more than 264 it just destroys the window.

The code :
_________________________________
CFileDialog m_ldFile(TRUE);
m_ldFile.m_ofn.nMaxFile = 264;
________________________________

I have no idea what to do

Dear Stream2000!

I am not quite sure (I don't have time to look deeper into it, but I think the reason for this is that if you increase the nMaxFile, you also have to provide a buffer for the m_ldFile.m_ofn.lpstrFile. If you don't provide a buffer the system will not allocate enough memory for all the selected files!
I hope this solves your little problem

Best regards

OPENFILENAME::nMaxFile specify the buffer size of OPNEFILENAME::lpstrFile. Make sure lpstrFile also has sufficient space.

    const int MAX_FILE = 1024;
    TCHAR tchFile[MAX_FILE];

    m_ldFile.m_ofn.nMaxFile = MAX_FILE;
    m_ldFile.m_ofn.lpstrFile = tchFile;
    ...
