I want to load a file. I have a Dialog with a "Load" button, i attach code
to it :

{
 // TODO ...
   CFile f;
   CFileDialog fd;
   fd.DoModal();
   f.Open(fd.GetPath(),CFile::modeRead | CFile::modeBinary);
   f.Close;

   Thank you for your help.

Stephane,

Here is code from where I did the same sort of thing.  I don't know what's going
wrong with yours, but maybe this will help.  The major difference here is I use
GetPathName() instead of GetPath().

CFileDialog FileList(TRUE, NULL, "*.XXX",OFN_HIDEREADONLY,
 "XXX Files (*.XXX)|*.XXX|All Files (*.*)|*.*||");
CString temp;
CFile XXXFile;
CFileException e;

// Change the title to something more appropriate than "Read"
FileList.m_ofn.lpstrTitle = "Select a XXX File to Load";

if (FileList.DoModal() == IDOK) {
     if(XXXFile.Open(FileList.GetPathName(),CFile::modeRead,&e)) {
    ...
    }
