And if you use multiselection and select all the files in one directory
where there are about 500 or so, it throws an exception "Too many files" or
something similar.
This is uselss when trying to read in sequences of images for analysis
etc...

This is code from my app:
#define MAX_FILES_IN_OPEN_DIALOG   2000
....
void CMRenameDialog::SelectFiles() {
     OPENFILENAME ofn;
     TCHAR FileName[MAX_PATH]={0}, *FileDir;
     unsigned long FileNameOffset=0;
     DWORD szFileDir = MAX_FILES_IN_OPEN_DIALOG*MAX_PATH;
     FileDir = (TCHAR *)malloc(szFileDir*sizeof(TCHAR));
     FileDir[0] = NULL;

     ofn.lStructSize = sizeof(ofn);
     ofn.hwndOwner = m_hWnd;
     ofn.hInstance = NULL;
     ofn.lpstrFilter = _T("All Files(*.*)\0*.*\0\0");
     ofn.lpstrCustomFilter = NULL;
     ofn.nMaxCustFilter = 0;
     ofn.lpstrFile = FileDir;
     ofn.nMaxFile = szFileDir;     // in TCHARS
     ofn.lpstrFileTitle = FileName;
     ofn.nMaxFileTitle = sizeof(FileName)/sizeof(TCHAR);
     ofn.lpstrInitialDir = m_SelectedFileDir;
     ofn.lpstrTitle = WINDOWS_OPEN_DIALOG_TITLE;
     ofn.Flags = OFN_ALLOWMULTISELECT | OFN_EXPLORER | OFN_FILEMUSTEXIST |
OFN_LONGNAMES;
     ofn.nFileOffset = 0;
     ofn.lpstrDefExt = NULL;
     ofn.lpfnHook = NULL;
     ofn.lpTemplateName = NULL;

     if (GetOpenFileName(&ofn)) {   <--- this is the line where execution

I created dir C:\Temp\Test 1000 which containde 1000 files:
TEMP_TEST 1000_COPY (1) OF EMPTY.TXT
TEMP_TEST 1000_COPY (2) OF EMPTY.TXT
...
TEMP_TEST 1000_COPY (801) OF EMPTY.TXT
TEMP_TEST 1000_COPY (802) OF EMPTY.TXT
TEMP_TEST 1000_COPY (803) OF EMPTY.TXT
...
TEMP_TEST 1000_COPY (999) OF EMPTY.TXT
TEMP_TEST 1000_COPY (1000) OF EMPTY.TXT

open dialog appears and I select all 1000 files, then MessageBox appear with
following text:
TEMP_TEST 1000_COPY (802) OF E
File not found.
Please verify the correct file name was given.

That's it, Rajko.
