Re: [comtypes-users] Getting AddressOfMember working?

In typeinfo.py, I've commented out the following line: #raise Check Me Using test_typeinfo.py as a starting point, I've got a script that attempts to use AddressOfMember in the following way: address = ti.AddressOfMember(fd.memid, fd.invkind) This results in the following error: Traceback (most recent call last): File C:\ax.py, line 31, in module address = ti.AddressOfMember(fd.memid, fd.invkind) File C:\Python27\lib\site-packages\comtypes-1.0.0-py2.7.egg\comtypes\typeinfo.py, line 316, in AddressOfMember self.__com_AddressOfMember(memid, invkind, byref(p)) _ctypes.COMError: (-2147317571, 'Wrong module kind for the operation.', (None, None, None, 0, None)) The best info I could find online is this: http://forums.codeguru.com/showthread.php?497293-Why-Exception-occured-getting-address-of-COM-function but there's no answer. MSDN says in http://msdn.microsoft.com/en-us/library/windows/desktop/ms221544%28v=vs.85%29.aspx: Retrieves the addresses of static functions or variables, such as those defined in a DLL. This seems to suggest that ITypeInfo::GetAddressOfMember works only for static functions or static variables, but not for methods of COM object.

Given that there was already an AddressOfMember function in typininfo.py (albeit blocked by a raise), I had hoped that it was possible but just unfinished.

Why do you need the address? What do you want to do with it? This info is quite valuable for reverse engineering. e.g. if a COM object exposes a function foo(), then where in the module is the actual code to handle foo()? -WD -- Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.

Why do you need the address? What do you want to do with it? This info is quite valuable for reverse engineering. e.g. if a COM object exposes a function foo(), then where in the module is the actual code to handle foo()? comtypes doesn't expose the address of the methods directly. However, with some advanced ctypes-wizardry you should be able to find out. Nevertheless I cannot help you with this.
