You may need to create and use a system driver, since you are trying to access hardware. Just throwing out a suggestion, that you may need to do. Simple Thanks and Regards, Brandon T. H.

If you only want to view the interface definitions, you can use a tool called OLE/COM Object Viewer that comes along with Visual Studio. From this tool select the menu option File -> View TypeLib... and point to the proxy-stub dll. But for this to work, the type library has to be packed into the DLL. «_Superman_»  _I love work.

Oh wow your a genius. Over all in the end, the cVariants value was wrong when the first array called va was created. It was too small, so the one you pointed out added a value that was not initialized, it ncreased the size of the array, in a space that was too small. So that's why the delete [] va crashed. So finally after week of messing with this, I broke the program down in 2, worked on the add mime until it was clean, and just added the code to read the current mimes. I put much weight on your suggestion, but did keep it in mind. Thanks Superman.

Maybe you should limit the objects lifetime to the lifetime of the thread. Currently the object is destroyed at any time by the GC in the GC thread. Try calling Marshal.ReleaseComObject before the thread ends, to guarantee a deterministic lifetime of the object.
