OpenGL Extension Viewer 6.2


I don’t know if this is the right forum for my concern:

When running “OpenGL Extension Viewer” an exception error is generated:

Unhandled Microsoft .Ne Framework exception in openglex.exe

Access error due to access to protected memory areas

In detail, a for-next loop is executed within the scan function. The command …

num = Win32.oevClientScan (i, num);
... cannot be executed with the parameters i = 0, num = 0.

Extract from the program code:

for (int i = 0; i <gvDevice.Contexts.Length; i ++)
viewController.LogPrintf ("Querying properties ...");
viewController.ReportProgress (i * 100 / gvDevice.Contexts.Length, gvDevice.Contexts [i]);
num = Win32.oevClientScan (i, num);
catch (exception ex2)
viewController.LogError (ex2.Message);

Error message:

Exception thrown: "System.AccessViolationException" in libGLVIEW.dll
An attempt was made to read or write to protected memory.
