I am trying to write a wrapper around a legacy COM object and install the wrapper into the GAC. The goal would be to automate the setup of specific configuration information the component requires, and make a common strongly typed interface for all of my applications to use.
My solution thus far is to keep an XML configuration file in the same directory as the original COM DLL, and load the configuration in the class constructor. Unfortunately, I have been unable to find the location of the registered COM dll…
How do I get the full file path of the COM dll referenced by a COM object interop dll?
Once you’ve created an object from the respective COM server, its DLL must have been loaded. Assuming that the underlying COM server is implemented in “mycomserver.dll”, you could use P/Invoke and call GetModuleHandle( “mycomserver.dll” ) — that gives you the path of the DLL.
