[wingide-users] Problems with wingdbstub.SuspendDebugWing IDE Support support at wingide.com

Hi, The API will only work if you're launching the debug process from outside of Wing. If you debug from within Wing, the debugger is already going by the time you reach the import of wingdbstub, so the module does nothing and doesn't set up the debugger API. When you ran from the command shell it also didn't work because there's a bug in SuspendDebug that needs fixing (oops, thanks for pointing it out!). However, you probably don't need to use the API anyway. At this point this is really only there for very unusual debugging scenarios. Try removing your calls to the API and placing the import of wingdbstub where you currently have the ResumeDebug call. This will delay starting debug until that line is reached. If you want to launch the process from the IDE, use the Execute items in the Run menu instead. This runs things outside of the debugger and lets wingdbstub do its work when it is imported. If you do need .wingdebugpw, it's in ~/.wingide on Linux/Unix, and inside profiles/[username] in your Wing installation on Win32. However, if both processes run as the same user then the debugger looks up the file automatically. Hope that helps... if not, please let us know.
