ERROR: In .\vtkWin32OpenGLRenderWindow.cxx

[ch_eb]

I use the vtkFormsWindowControl for displaying. After starting the program it runs perfect for a while. Then the following error occurs:

ERROR: In .\vtkWin32OpenGLRenderWindow.cxx, line 238
vtkWin32OpenGLRenderWindow (053AD030): wglMakeCurrent failed in MakeCurrent(), error: The requested resource is in use.

I tried to debug in the C++ code of the vtk library. It seems that the program crashes during mouse interactions. I used the pdb files for debugging. Finally the program crashes because of a System Violation Exception.

Callstack shows the following in "vtkplanewidget.cxx" :

void vtkPlaneWidget::OnLeftButtonDown()
{
  int X = this->Interactor->GetEventPosition()[0];

Maybe the Interactor is null...
I try to find a solution for this problem for days but I have no idea...

Any suggestions? Thanks for help!

I have the same proplem... and no solution for it...

I found the reason in my project :) it is:

renWin.AddObserver((uint)vtk.EventIds.AbortCheckEvent, this.AbortCheckCallback);
}
..

private void AbortCheckCallback(vtkObject caller, uint eventId, object clientData, IntPtr callData)
{
            vtkRenderWindow renWin = vtkRenderWindow.SafeDownCast(caller);
           
            if(renWin != null)
            {
                //renWin.MakeCurrent();
                if (renWin.GetEventPending() != 0)
                    renWin.SetAbortRender(1);
            }
}

I comment "renWin.AddObserver((uint)vtk.EventIds.AbortCheckEvent, this.AbortCheckCallback);" and have no more such exception

But I need this abort, any idia how to make it correctly?
