DirextX, Windowed Mode : Lock kills system !

udragon · 2000-02-03T12:49:51

Hi ! I''m used of writing full-screen DirectX 6.0 applications, but now I''m writing a tool in windowed mode.... Now, for some reason everytime my code reaches the surface->Lock(... ) function the system halts and I have to reboot. I''ve tried both to lock the whole surface (NULL) and a rectangle, no difference. I debugged several times and verified every return code, everything seems to work fine,... until I reach the line with ''Lock''. Any ideas ? Kind regards, Christophe ''Uther Pendragon'' Cap PS. I already installend my ''MonsterFusion'' drivers as well as the directX SDK

Hi !

Finaly ! I found it... pfff.. I was goin'' nuts !
(If not already

)

It was indeed the locking that killed my debug (screen) output.

An ASSERTion failure occured somewhere, and I didn''t see it because of the locking.

After resolving the problem everything was ok !

Thanx to all of ya'' for the swift response !

Bye !

PS. Just for your information : DDLOCK_NOSYSLOCK néver works for primary surfaces, it''s just ignored by DirectX
