Re: [Dev-C++] Questions on WS_TABSTOP, WS_DISABLED and BitBlt

Thanks for everything...
I'm still in trouble with the TAB thing... I added WS_EX_CONTROLPARENT to
the parent window, but I don't know, for some reason it still won't go, I
haven't tested yet the disabling thing, I used to use
SendDlgItemMessage(blah, blah, WM_ENABLE, ...)
but it didn't work properly, wouldn't ti be the same?
and thanks the BitBlt is now working, stupid me, it was a momentary lapse=
,
thanks...
