HI I have tefollowing Problem with an Solidworks API PlugIn.

When a File is locked (checked out) by a user, I want to check if there is a Comment and if yes, it should pop up a messagebox.

With the Hook PostLock or Prelock this works, but then when I want to unolck the File it says, that the file is opend in another application.

Here is the Code:

public class PDM_AddIn : IEdmAddIn5 { // PdmFile attribute
