thanks for your reply!

I tried your first suggestion and it works well now. I post the code
below in case anyone is interested.

I have not tried the second way but I read many posts about issues
with SetForegroundWindow() under Win98 and up. The first way seems to
be more reliable.

thanks again,
Nick


//assuming hwnd is the window handle of a TStringGrid
//in another application
DWORD threadId = GetWindowThreadProcessId(hwnd, NULL);
DWORD ourThreadId = GetCurrentThreadId();

AttachThreadInput(threadId, ourThreadId, TRUE);

unsigned char keyboardState[256];
GetKeyboardState(keyboardState);
keyboardState[VK_CONTROL] |= 0x80;
SetKeyboardState(keyboardState);

SendMessage(hwnd, WM_KEYDOWN, VK_HOME, 0);
SendMessage(hwnd, WM_KEYUP, VK_HOME, 0);

GetKeyboardState(keyboardState);
keyboardState[VK_CONTROL] &= ~0x80;
SetKeyboardState(keyboardState);

AttachThreadInput(threadId, ourThreadId, FALSE);
