Folks after the following code uses the handle
of Panel1, I cant get the panel back to a useable state - that it was
initialised in:
hWndC := capCreateCaptureWindowA('My Own
Capture Window',
WS_CHILD or
WS_VISIBLE,
0, 0,
panel1.Width, panel1.Height,
panel1.Handle, 0);
WS_CHILD or
WS_VISIBLE,
0, 0,
panel1.Width, panel1.Height,
panel1.Handle, 0);
{now I null hWndC, but I would also like to
re-instate the Panel as it was intialized}
if hWndC <> 0 then
begin
SendMessage(hWndC, WM_CAP_DRIVER_DISCONNECT, 0, 0);
hWndC := 0;
end;
SendMessage(hWndC, WM_CAP_DRIVER_DISCONNECT, 0, 0);
hWndC := 0;
end;
{changing properties of
panel1.bringtofront/visible/enabled dont effect. Nulling hWndC does not destroy
the panel}
Last question: if I create a bitmap in a subroutine the bitmap
is cleared on exiting the routine right?? I dont have to bitmap.free before
exiting?? (why I ask is that I see some code written using subproceedures and
the bitmap is freed prior to exiting.)
ideas??
Tks,
