Open a TOpenDialog in detail view

Problem/Question/Abstract:

I use the standard OpenDialog to select a file to open. To see the creation date of a file, I have to change the view to Details (in fact my preferred view) every time. I was looking for an attribute (in the Options) to configure, that always detail view is selected when the OpenDialog is activated. However I didn't find anything. Does somebody have a hint for this problem?

Answer:

Add this code to the OnFolderChange event of the dialog:

procedure TForm1.OpenDialog1FolderChange(Sender: TObject);
var
  H, H2: THandle;
begin
  H := FindWindowEx(GetParent(OpenDialog1.Handle), 0, PChar('SHELLDLL_DefView'), nil);
  H2 := FindWindowEx(H, 0, PChar('SysListView32'), nil);
  if (H <> 0) and (H2 <> 0) then
  begin
    SendMessage(H, WM_COMMAND, $702C, 0);
    Windows.SetFocus(H2);
    PostMessage(H2, WM_KEYDOWN, VK_SPACE, 0);
  end;
end;
