How to make the event IncludeItem of TOpenDialog work?

I have set the ofEnableIncludeNotify property to true and written this code.......

procedure TForm1.OpenDialog1IncludeItem(const OFN: TOFNotifyEx;
  var Include: Boolean);
begin
 Include:=False;
end;

However, still all files are displayed when I execute the OpenDialog. The above code does get trigerred for every file, but soemhow the Include variable has no effect.

I know it is a bug in Microsoft implementation, (plenty of websites on internet refer to this)........... but does anyone know of a work around?

I am using Delphi 7 on Windows XP. Application deployment would be on Windows 2000 & XP, XP SP1, XPSP2 machines.

It is not exactly what you want, but may be you can apply
filter. In this sample only
a.*
b.*
*.tiff
files will be displayed.


procedure TForm1.Button1Click(Sender: TObject);
var
  ofn:tagOFNA;
  szFile: array [0..260] of char;
begin
  inherited;

FillChar(ofn, sizeof(tagOFNA), 0);
ofn.lStructSize := sizeof(tagOFNA);
ofn.hwndOwner := handle;
ofn.lpstrFile := szFile;
ofn.lpstrFile[0] := #0;
ofn.nMaxFile := sizeof(szFile);
ofn.lpstrFilter := 'My Files'#0'a*.*;b*.*;*.tiff'#0;
ofn.nFilterIndex := 1;
ofn.lpstrFileTitle := nil;
ofn.nMaxFileTitle := 0;
ofn.lpstrInitialDir := nil;
ofn.Flags := OFN_PATHMUSTEXIST or OFN_FILEMUSTEXIST or OFN_EXPLORER ;
  GetOpenFileName(ofn);
end;

Dear Vadim,

Thank you for your quick response.

Could you email me (guru.pannu@pri.co.uk) a complete Delphi project (.pas, .dfm, .dpr) explaining what you have just written?

I haven't been able to understand your answer fully.

Thx. Guru
