Can't get a rendering context, wglCreateContext fails

[jj2007]

Should I post the changed code?

Thanks, no need for that. So for test ct, 65536*16-1 you see nothing, for test ct, 256-1 the screen feels rapidly? That would mean your message loop is a lot slower than ours ::)

Attached a version that allows modifying the speed via the menu.

i can see a few immediate possibilities..
1) the multi-media timer isn't working as expected on Gunther's machine
2) the OpenGL init must be performed when the window is visible
3) OpenGL ver 1.x code isn't happy on a 4.4 machine

in this one, i moved the init code to the main proc

Rapidly rotating triangle - but I'd like to clarify that message loop thing, see attachment to my post above.

[dedndave]

that one works as expected on my machine, Jochen
about one line of numbers per second (same as the previous one)
is that what you wanted ?

I believe you, Dave. I'd like to see what Gunther's machine does when choosing the menu options :icon_mrgreen:

[dedndave]

didn't even notice the menu - rofl
they work here - let's see what happens on Gunther's

i need more coffee   :(

[dedndave]

hopefully, TWell will show up today
it would be nice if he would attach an EXE made with the C-version render module
i am having trouble building it, here

[TWell]

In Reply #144 look output folder for obj

[dedndave]

now, i am a little lost.....

on TWell's code...
he posted a ZIP file named SmallOgl_ASM_C, supposedly using the C render module
and - that seems to work on Gunther's machine
and he says that the C version works, but the ASM version does not on his own machine
however, when i disassemble the EXE, it is clearly using the render code that i wrote in ASM
it would be great if he would attach both EXE's for a side-by-side comparison
i am having trouble building the C version, as i am not set up the same with Pelle's

it may also be helpful if both Gunther and TWell would post results from the version test i posted here

http://masm32.com/board/index.php?topic=2582.msg27374#msg27374

it generates a text file with version info   :t
please post or attach the text - thanks

But it is using that C version to rendering.

many thanks, TWell   :t

i see, now - the EXE actually contains both modules
and - i spotted an error in my code
i used FST, when i should use FSTP (i thought the POP was implied)

but, this is interesting
here is the C version code for that part of the render routine

it would seem it converts doubles to singles each time render is called
the only one that changes is the first value in the array

let's see....

how it's spinning...

great !

Hi Dave,

   Just for jollies I will mention that yesterday I went to my Mother's
house and ran some of your older SmallOgl program and foo.exe.
The GUI and windowed CLI went as expected.  But when run from
a full screen session, they all ran in the background as processes.
Her machine had been infected (a while back), and then cleaned.
When infected, the command prompts were more or less disabled.
Meaningless data point I suppose.

   Back to today.  Results from SmallOgl_ASM_C.zip in Reply #144.

   I hope you find this interesting, and perhaps useful.  At least
it is a bit different.
