I have made a VB.Net Add-In for Inventor 2011, in a few functions it opens one or more files or sets a reference to already opened files. The release of the resource to this documents seems to be the problem.
In PDM (Productstream Pro) we want to change document states and there for the documents have to be closed in Inventor. When using some Add-In functions prior to the state change in PDM, we get a message from PDM that Inventor still has the files open but inventor does not show any open files (of course we can not see files that were opened in the background).
Only manual operation to solve this is to close inventor or open the drawing and the part used on the drawing and close them top down (drawing first, then part).
In short, I'm stuck with open files that don't seem to be open.
I think this is because the add-in sets a reference to the part used on the drawing and then changes something in the drawing.
How do I release the resources correctly?
Or, what else can I do to prevent this from happening?
maybe you could post this question in the Customisation area of the forum.
also if possible post your code so we can see what your functions are working on.
