    Call managed code (c#) from unmanaged code (VC++ 6.0)


    Please excuse my english. I'm from germany.
    Does anybody know if it's possible to call managed code (c#) from VC++ 6.0? I already found the ManWrap Library, but this library does not work with VC++ 6.0.

    I hope somebody knows an alternative.

    Thank you very much in advance

    I've never tried, but I would guess the only way it could work is if it used an extern "C" interface with primitive data types. Otherwise the ABI would be incompatible.

    To call managed code, you need to create an ActiveX wrapper for the .Net component. I'm not sure how automated this works - it should be pretty simple.

    Once you've got the wrapper, you can use classical COM mechanisms to use it.
    All the buzzt!

    A word of warning, outside of using a COM intermediary or similar there is not a whole lot of interaction that can be done between managed and unmanaged objects themselves. .NET doesn't like you trying to introduce foreign data into its internally controlled objects.
