How to show the new Common File Dialog in MFC Apps in Windows 2000.

Sample Image - win2000fd.jpg


If you've tried using the MFC common dialog class CFileDialog in Windows 2000, you'll notice that it will show the 'old' file dialog even with the OFN_EXPLORER flag set. The reason for this is that Windows 2000 uses OFN_ENABLE_HOOK flag to determine which dialog to use. If the OFN_ENABLE_HOOK flag is set, Windows 2000 uses the old dialog, if not, it uses the new dialog. CFileDialog in MFC uses the OFN_ENABLE_HOOK flag which explains why all MFC applications display the old dialog and regular applications (not compiled with MFC) show the new dialog, if run in Windows 2000. For a more detailed explanation, look in April 2000 issue of MSDN pp.138,139. I've managed to get around this by overriding some of MFC's virtual functions and not allowing MFC to set the OFN_ENABLE_HOOK flag.

Step 1:

Insert CKSDialog into your MFC project. Add the following header file to your App's implementation file.

#include "KSDialog.h"

Step 2:

Add the following function headers to you App's header file.

virtual BOOL DoPromptFileName(CString& fileName, 
  UINT nIDSTitle, DWORD lFlags, BOOL bOpenFileDialog, CDocTemplate* pTemplate);

Then enter the functions body in the your App's implementation file.

BOOL CMyAppApp::DoPromptFileName(CString& fileName, 
  UINT nIDSTitle, DWORD lFlags, BOOL bOpenFileDialog, CDocTemplate* pTemplate)
  CKSFileDialog dlgFile(bOpenFileDialog);
  dlgFile.SetStringFilter("My File Format (*.mff)|*.mff|My File Format File (*.mff)");
  return dlgFile.DoPromptFileName(fileName,nIDSTitle,
      lFlags,bOpenFileDialog, pTemplate);

Step 3:

You need to override your App's CMyAppApp::OnFileOpen() function, this can be done easily through the class wizard. Enter the following code for OnFileOpen():

void CMyAppApp::OnFileOpen() 
    CString newName;
    if (!DoPromptFileName(newName, AFX_IDS_OPENFILE,
        return; // open cancelled


Step 4:

Now, you need to override a Windows function in your document class. This will give you the ability to save using the new dialog. So in CMyAppDocument header class, override the DoSave() virtual function.

virtual BOOL DoSave(LPCTSTR lpszPathName, BOOL bReplace=TRUE );

Add the implementation of the function in your Document's implementation file.

BOOL CMyAppDoc::DoSave(LPCTSTR lpszPathName, BOOL bReplace)
    CKSFileDialog dlgFile(FALSE);
    return dlgFile.DoSave(lpszPathName,bReplace);

You're done.

Now, when you try to open or save a document, the Windows 2000 file dialog should pop up. See if you can make the dialog pop up in the center of your client window instead of the top left, the first time it's called. I haven't been able to do this as of yet. If I try to hook into the messaging system of CFileDialog to override WM_INITDIALOG, Windows 2000 thinks that it has to show the old style dialog.

If you want the new file dialog to pop up generically, meaning not through the standard Windows Document/View Open, Save, Save As messaging system, just use the following code: (this is also shown in the demo project). You don't have to go through the above code, just use it like a regular CFileDialog.

For saving:

const char szFilters[]="Some Kind of Files (*.fn2)|*.fn2|All Files (*.*)|*.*||";
CKSFileDialog dlg (FALSE, "fn2", NULL, 

if (dlg.DoModal()==IDOK)
    //some file writing code here

For reading:

const char szFilters[]="Some Kind of Files (*.fn2)|*.fn2|All Files (*.*)|*.*||";
CKSFileDialog dlg (FALSE, "fn2", NULL, 

if (dlg.DoModal()==IDOK)
    //some file reading code here
