I have created an extra TSpeedButton on my TOpenDialog and would like to change the 
active directory if the user clicks it. If I change the current directory, nothing 
happens.

Answer:

1   { ... }
2   hDlg := GetForeGroundWindow;
3   repeat
4     {Sending the path. Try until the dialog has received it}
5     SendDlgItemMessage(hDlg, 1152, WM_SETTEXT, 0, Integer(PChar(sDir)));
6     L := SendDlgItemMessage(hDlg, 1152, WM_GETTEXTLENGTH, 0, 0);
7     Application.ProcessMessages;
8     if Application.Terminated then
9       Exit;
10  until
11  L <> 0;
12  {And now click OK}
13  SendMessage(hDlg, WM_COMMAND, 1 + BN_CLICKED * $10000, GetDlgItem(hDlg, 1));
14  {Clear}
15  SendDlgItemMessage(hDlg, 1152, WM_SETTEXT, 0, Integer(PChar('')));
16  { ... }
