Hi All,

Using 9600 GT driver 6.14.11.8120
WinXP

During running our application the Thread that is responsible for
drawing get "Freezed"
Code of rendering

Code:
if(m_pGLContext)
{
BOOL bRes = m_pGLContext->MakeCurrent();
if(bRes)
{
const BSTAT eRet = m_pGLContext->Render(); // Some OpenGL calls
CDC* pDC = GetDC();
m_pGLContext->Swap();
ReleaseDC(pDC);
} else
{
m_pGLContext->ReleaseCurrent();
return;
}

m_pGLContext->ReleaseCurrent();
}

where MakeCurrent() and ReleaseCurrent () stands for:

Code:
BOOL COGLContext::MakeCurrent()
{
#ifdef _DEBUG
const DWORD dwThread = GetCurrentThreadId();
UI_ASSERT_AND_LOG(m_cOwner.IsCurrent(), "Sharing a context between
threads is a bad idea!");
#endif
const HGLRC hGLRC = wglGetCurrentContext();
if(hGLRC != m_hGLContext)
{
const BOOL bRet = wglMakeCurrent(m_hDC, m_hGLContext);
if(!bRet)
{
const DWORD dwError = GetLastError();
return FALSE;
}
}

return TRUE;
}

void COGLContext::ReleaseCurrent()
{
wglMakeCurrent(NULL, NULL);
}
after a while , most of the times in Release build the Drawing thread
is freezed.
Last code statement is wglMakeCurrent(NULL, NULL);

It seems that the thread is stuck in the Video adapter dll......

here is the call stack

Not too many systems programmers 'round these parts. Can't remember a
time when there was either... </oldcoot>

You'll stand a better chance with NV developer relations or MSDN honestly.
