cadImage.LoadFromFile() OverflowException

Hello

I got an issue 'System.OverflowException' at cadimage.LoadFromFile().
It happens to some cad files.
I attached an .dwg file.

And the error message is below
-----------------------------------------------------
Exception thrown: 'System.ArgumentException' in System.Drawing.dll
Exception thrown: 'System.OverflowException' in CADImport.dll
Exception thrown: 'System.OverflowException' in CADImport.dll
.

during 60 sec.

Managed Debugging Assistant 'ContextSwitchDeadlock'
The CLR has been unable to transition from COM context 0x4a0e62a0 to COM context 0x4a0e6178 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.

Code is...

Code: Select all

CADImage cadImage = CADImage.CreateImageByExtension(dwgFilePath);
cadImage.LoadFromFile(dwgFilePath);

Thank you.
