You need to call the SetCapture(HandleOfMyWindow) function. The parameter is the handle of the window that should capture the mouse, for example MyForm.Handle.

When you have finished you have to call the ReleaseCapture function.

Good luck, Rick

I guess I was not very clear, I need the to cursor to stay within the borders of my active window. The SetCapture only directs the input to the window specified but still lets the cursor go else where on the screen. Here is what the help file says:

"The SetCapture function sets the mouse capture to the specified window belonging to the current thread. Once a window has captured the mouse, all mouse input is directed to that window, regardless of whether the cursor is within the borders of that window. Only one window at a time can capture the mouse."

Thanks for the quick responce!

Use ClipCursor.

Example:
procedure TForm1.FormCreate(Sender: TObject);
var
    r: TRect;
begin
    // This restricts the cursor to Form1's borders.
    r.Left := Left;
    r.Top := Top;
    r.Right := Left + Width;
    r.Bottom := Top + Height;
    ClipCursor(@r);
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
    // This allows the cursor to move anywhere.
    ClipCursor(nil);
end;

Hope this is what you're looking for.
