From Angel Popov <jumpo@bitex.com>
|
|
|
|
Here are two snips from a dicussion in the OpenGL Gamedev list that explains
|
|
how this problem can be fixed:
|
|
|
|
"There are 5 common DCs available in Win95. These are aquired when you call
|
|
GetDC or GetDCEx from a window that does _not_ have the OWNDC flag.
|
|
OWNDC flagged windows do not get their DC from the common DC pool, the issue
|
|
is they require 800 bytes each from the limited 64Kb local heap for GDI."
|
|
|
|
"The deal is, if you hold onto one of the 5 shared DC's too long (as GL apps
|
|
do), Win95 will actually "steal" it from you. MakeCurrent fails,
|
|
apparently, because Windows re-assigns the HDC to a different window. The
|
|
only way to prevent this, the only reliable means, is to set CS_OWNDC."
