cadImage.LoadFromFile() System.NullReferenceException

[Sing]

Hello

I have downloaded the latest version of CADImport (14.1.0.45509) and run the code cadImage.LoadFromFile().
I got a similar error to my old topic viewtopic.php?f=15&t=10460&sid=cc7efb42 ... 523ee82e3b.

Error message is below.

Exception thrown: 'System.NullReferenceException' in CADImport.dll

Managed Debugging Assistant 'ContextSwitchDeadlock'
The CLR has been unable to transition from COM context 0xf83b2aa0 to COM context 0xf83b2978 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: Select all

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

I attached the .dwg files that occurred the errors.
This error makes a delay in loading .dwg files.

Thank you

Hello,

Thank you for the files.

Unfortunately, we couldn't reproduce the System.NullReferenceException in CADImage.LoadFromFile(). Could you please specify a version of .NET Framework used by your project or just attach a simple test project to your post? It will speed up investigation of the problem.

Hello

The version of .NET Framework is 4.6.1.
I attached a sample code.
I could not attach a .dwg file because of file size.
Download .dwg files I attached before.

And please reply to my old post (http://www.cadsofttools.com/forum/viewt ... =15&t=1046)
if you have some time.

Thank you.

Hello,

Thank you for the project, but, unfortunately, we still couldn't reproduce the problem.
