Managed Debugging Assistant 'LoaderLock'??? - HELP

    General discussion

  • Hi.

    Here is the situation. I was asked to create a little demo program in order to show how a C# application could easily use our COM DLL's. The C# app is very simple - just a single button that creates an instance of an object from the COM dll. This COM dll displays a dialog and provides a list of various tasks, and depending on which task is selected, CoCreateInstance is called and another COM object is created and another dialog is displayed.

    I added the COM dll to my project by adding a reference to the DLL. I then 'new' an object from this DLL and tell it to display its dialog.

    Whenever I make a selection on the dialog displayed by the first COM dll, perform some work on the next COM objects dialog created by calling CoCreateInstance, and then close everything, I get a Managed Debugging Assistant 'LoaderLock' error!!

    I dont understand what is going wrong. I read these articles but I don't understand how to resolve my issue:

    http://msdn.microsoft.com/en-us/library/ms172219(VS.80).aspx

    I tried looking at the call stack, but there are no symbols loaded for any call stack frame. As far as I know, the two COM DLL's in question are purely native.



    Any help would be greatly appreciated!!

  •   Hi, 
     
    Could you show us how the CoCreateInstance work, nor it's hard to reproduce the situation, we're just guessing.

    Best regards,
