Hello everyone!

I have an application that opens many windows. Sometimes, I get wglCreateContext() returns 0 and GetLastError() returns 0xc007001f.

It happens on Intel graphic cards only.

Did someone see it? Someone knows what it is?

Thanks!

Seems that this is kind of "reserved" error code, the one with nowhere to find the meaning. Try to look in Application log of Event Viewer (that is what they often recommend in such cases).

Are you creating your windows with the CS_OWNDC flag?

For now, Intel has poor support for OpenGL. They have entered into a technology agreement with NVidia, so future cards may have better support. You may just be exceeding the capacity of the Intel Graphics Drivers.

In the past I've used the Mesa OpenGL DLL to work around issues with their drivers. This may or may not solve your problem.

As a rule, I tell clients not to use Intel Graphics cards with OpenGL products.

I recommend NVidia or ATI.
