Call function in external dll in Revit2016R2 doesn't work.

[pmeigneux]

Hello,

I have an addin that calls a dll (not Revit). This works with Revit 2015 for all update / release, for Revit 2017, Revit 2017.1 and Revit2016 to R2.

But it does not work with Revit 2016 R2 and for the following update.

Error: System.AccessViolationException

Why ? do you have an idea ?

When those things happen please also post the stack trace.

At least we have an idea of what your dll was trying to do.

Hello,

I added a dumpdata.zip file

Please check your VS project build first (64 vs 32 bit) maybe this is the problem. If not please clarify more about what you are doing.

If this reply satisfies your need please don't forget to mark it as an answer.

hi,

I'm in 64 bits.

Try to set it to Any CPU and recompile then run.

[pmeigneux]

Sorry, i test "any CPU" no change..

[Mustafa.Salaheldin]

OK have you tried to debug the code line by line to trace where the exception occurs?

[pmeigneux]

Hi,

see attachment.

Dear Philippe,

Next step: verify that the call into Lmx.Checkout really works, and then debug into that.

I hope this helps.

Best regards,

Jeremy

Hi Jeremy,

I do not have the code, only a dll.

Do you have an idea why the same code works for all revit versions (2015 to 2017) except 2016 R2?

No, sorry, no idea. Incompatible .NET framework? Can you decompile and look at the IL? Can you contact the vendor?
