Initialize the strBuffer by putting a 0 as the first character.

strBuffer[0] = 0;

what is going on is that the FileDialog thinks that you are supplying it an
initial filename in the lpstrFile variable, and since its uninitialized, it
is crashing.

I want to select multi files using CFileDialog:

CFileDialog FileDlg (TRUE, NULL, NULL, OFN_ALLOWMULTISELECT );
TCHAR strBuffer[4096];
FileDlg.m_ofn.lpstrFile = strBuffer;
FileDlg.m_ofn.nMaxFile =sizeof(strBuffer);

if (FileDlg.DoModal()==IDOK)
{
CString csFname;
CStringArray m_strArray;
m_strArray.SetSize(0);
POSITION pos = FileDlg.GetStartPosition();
while (pos != NULL)
{
csFname = FileDlg.GetNextPathName(pos);
TRACE("%s\n", csFname);
m_strArray.Add(csFname);
m_CListBox_ListBox.AddString(csFname.GetBuffer());
}
}

The error is that FileDlg.DoModal() give error :

"Unhandled exception at 0x00000000 in ReadFile.exe: 0xC0000005: Access
violation reading location 0x00000000."

What I am missing?
