You could try to redirect the messages of the button.

IOW:

YourVariable := MessageLoopOfStartButton;
MessageLoopOfStartbutton := YourCustomMessageLoop;

In YourCustomMessageLoop you can pass every message to the former message-loop except for the click-message, which you can handle yourself. This way, the button will never notice when the user clicks it

Correct me if I'm wrong but ... Longhorn is Vista (or the former name of vista) isn't it?

Yes i messed it up a bit i mean Longhorn 4074 .Vista is 6001(SP1)

Could you make an example?

An example ...... i can show you how to do it
(As I have no Delphi installed I dunno if it compiles ...)

First, you need a variable that holds the old WndProc. A Pointer should do the job.

To get the pointer to the WndProc you can call GetWindowLong(), to process the messages in your program, you need a seperate function

Delphi-Quellcode:

var
  OldWndProc: Pointer;

begin // Change WndProc
  OldWndProc := GetWindowLong({Handle to the Button}, GWLP_WNDPROC);
  SetWindowLong({Handle to the Button}, GWLP_WNDPROC, @NewWndProc);
end;

function NewWndProc(hWnd: HWND; uMsg: UINT; wParam: WPARAM; lParam: LPARAM): LRESULT; 
begin
  if ({The Message you want})
    // Handle Message
  else // Call old WndProc
    CallWindowProc(OldWndProc, hWnd, uMsg, wParam, lParam);
end;

Something like that

To get the Handle of the button, you can use FindWindow.

You can find additional stuff by searching for "subclassing"

You don't even need GetWindowLong. SetWindowLong returns the previous value of the specified attribute. You also avoid a possible race condition if you remove the call.
Note that changing the WndProc only works for Vista. According to the documentation you can't set a new one for a window in a different process.
