Hey Paul,

WinFBE 1.5.6 on Windows 7-64
WinFBE\Examples\WebGL\NeHe_06\WebGL_NeHe_06.bas->exe
Using WinFBx Ver 1.0 aka-> -i D:\Free\bi\Roca\WinFBx\
32bit FBc compiler works fine,
but with both FBc-64bit 1.05 and FBc-64bit 1.06, exe will GPF when clicking the {x} close button,
the Escape key to exit will work fine.

[José Roca]

Strange. Works fine in my computer (Windows 7).

If you have DebugView, it can be debugged by adding

#define _CAXH_DEBUG_ 1

before the includes.

Same thing this morning after a fresh reboot.
Here is 3 logs.
1) 64{x}ButtonGpf.txt -> GPF via [X] button. A messagebox after the GetMessageW WHILE/WEND will never show.
2) 64EscKeyNoGpf.txt -> Exit via Escape key, no GPF
3) 32bitAllwaysOk.txt -> Exit via [X] button, no GPF

[José Roca]

And the WebGL_NeHe_04 and WebGL_NeHe_05 examples work? They do the same. The only change is the jscript code. (I forgot to state that the jscript code was taken from http://learningwebgl.com/blog/?p=571 ).

The only difference that I can see in the log file for the one that is GPFing is that the web page is keeping a reference to the WebBrowser control.

Try adding this code to WndProc to see if it makes a difference:

      CASE WM_SYSCOMMAND
         ' // Capture this message and send a WM_CLOSE message
         IF (wParam AND &hFFF0) = SC_CLOSE THEN
            SendMessageW hwnd, WM_CLOSE, 0, 0
            EXIT FUNCTION
         END IF


[Pierre Bellisle]

Yep, the WM_CLOSE is mandatory on my machine to avoid the GPF with WebGL_NeHe_06.bas.
Tested a dozen times.

Now...
I did try WebGL_NeHe_04.bas and WebGL_NeHe_05.bas...
They both crash in 64 and both work fine in 32.
WM_CLOSE does not have any effect on the result.


I did try under Windows 10, all works fine.
I did try under Windows 8.1, all works fine.

[Pierre Bellisle]

At this point, it could make sense to have some others to test on their Windows 7 machine.
Mine is pretty clean, but if I'm the only one to have the problem then
it might be related to something unique and doesn't need to be investigated.
I will do some other test later if I got time...

[Pierre Bellisle]

OK,
I did a lil REM this and REM that to narrow down the problem.
Turns out that if I comment out "pwb.Navigate(wszPath)" in any of the three files,
I got a blank window of course but no more GPF.


Added 01: If I set the line as pwb.Navigate("about:blank") then no GPF
Added 02: If I replace Index.html with a simple html file then no GPF.
Added 03: So CWebCtx.inc/FUNCTION CWebCtx.Navigate and Index.html could be looked at...
Added 04: Narrowing a lil bit more, commented  JavaScript  <!â€" glMatrix-0.9.5.min.js â€"> in index.html stopped the GPFs.

FYI - I'm back working on the visual designer. Hope to have something good to show for the next editor update.

[Paul Squires]

...using Jose's WinFBX is making coding the WinFBE editor and visual designer so much easier. Unicode is easy using Jose's library.

[José Roca]

I no longer use STRING except when I need a quick way to allocate a byte buffer. Variants have also become very easy to use. Unicode is the way to go because most of the world needs it.
