Connecting windows in COM mode

Question

Is there a tool available that intercepts Windows COM runtime? I want to see all the instances that are created, view requests to their interfaces, method calls, etc.

Thanks!

Answer 1

You can try Jonas Blunck COMTrace - I'm not sure if it works on Windows 7, but it's worth a try.

• MS Detours DLL (http://research.microsoft.com/en-us/projects/detours/)
• " COM" (http://www.microsoft.com/msj/0399/com/com0399.aspx). Don Box ( " COM Don Box"?: -)

Answer 4

COM- In-proc - CoCreateInstance() CoGetClassObject() , . COM-. , ATL, , - , QueryInterface(), , .

This is not very successful, but is a direct result of the implementation of COM servers in proc. A developer can use Process Monitor to notice registry calls that match ClassId-> Dll mapping and extensive tracing inside a COM object to see what happens on. ATL has a bunch of useful materials (for example, the COM_INTERFACE_ENTRY_FUNC_BLIND macro) to enable tracing.
