Can't get a rendering context, wglCreateContext fails

[dedndave]

Thanks Marinus, Steve, and Jochen   :t

Marinus and Jochen - i take it the program works and closes correctly ?

Steve - great info
although, i'm having a little trouble matching text files to machines

well - 2 of them, i figured out easy enough   :P
OPENGLPM.TXT, Windows 98, P-MMX
OPENGLP3.TXT, Windows 2000, P-III

not sure which is which, here
OPENGLP5.TXT, OpenGL Version: 1.3.5014 WinXP Release
OPENGLCM.TXT, OpenGL Version: 1.3.3413 WinXP Release
Windows XP, IBM Laptop
Windows XP, Sony Laptop

taking a guess... OPENGLCM.TXT goes with the IBM laptop

so, to try a little "process of elimination"....
in this one, i have disabled the init common controls code and removed the manifest from the RC file
i also disabled the multi-media timer and made a single call to render the triangle

that should tell us if it's an OpenGL problem, or something else
of course, it could be more than one issue - lol

by the way....
i opened a console window and hit Alt-Enter to get full-screen
(probably the first time i have done that on this machine - lol)
when i run the SmallOgl5 program from the command line,
the full-screen console minimizes and the GUI app runs (no problems)

Hi,

   You got it.

OPENGLP5.TXT, OpenGL Version: 1.3.5014 WinXP Release

   No, it was for the Mobile Celeron in the Sony Vaio.  P5 is the
Pentium M in the IBM ThinkPad.

   Yes, you drop (rise?) back to the desktop GUI.  Rather consistent
on all four here.

Hi Dave,

SmallOgl.exe works on both (Windows XP (VM) and Windows 7 64 bit), but nothing rotates. The triangle is static.

Slowly rotating triangle on my XP SP3... in contrast to the one I posted in reply #89, which rotates very fast on XP and slowly on W7-32. OpenGL seems to be a mess...

Jochen,

That's probably depending on the implementation in different operating systems. I've no other explanation.

Jochen, Gunther, thanks again for testing
but, the one i am hoping works correctly on newer operating systems is SmallOgl5 in Reply #108
the triangle should rotate at 1 degree per mS, and the close button should work correctly

now, Steve (FORTRANS) has some older machines
one of them is even a win 98 machine, one is a win 2000 machine, and 2 older XP laptops
i am trying some different things to see why things are different, there
i am a little surprised that we have had any success at all on the win 98 machine - lol

at any rate, some of these are intended just for Steve, really, as we try to sort out the differences
the current "i hope this works" version is SmallOgl5 in Reply #108, here...
http://masm32.com/board/index.php?topic=2582.msg27362#msg27362
it seems to have passed most of the tests, except Gunther's win7-64 test
and, of course, Steve's older machine tests

it works fine under XP but leaves an empty screen under Win 7. It's tricky.

ok Gunther - thanks again for testing   :t
i was hoping that one would work correctly for you   :(

it seems to work on other win7-64 machines
perhaps the issue is InitCommonControlsEx, manifest, and a non-English win7-64
i seem to recall Hutch experienced similar results on one of his tests
i'll have a look at his stuff to see what i can learn from it

[Gunther]

Dave,

That would make sense.

Gunther

[dedndave]

another possibility....

maybe the problem will go away by making 2 calls to ChoosePixelFormat   :P

what CPU does your win7-64 machine have, Gunther ?

I'm afraid Gunther has i7 Ivy Bridge CPU with on-chip graphics
