I have a COM Client and a COM Server, the COM Server holds an Interface exposed by the client, now the client is actually just an EXE, how do I make sure that the Interface exposed by the client is visible to the Server? Because when I call CoCreateInstance now on that interface in the server I get a E_NOINTERFACE and I suspect it's bec...
Is the above possible? Can I do this: IUnknown *punk; punk->QueryInterface(IID_MyInterface, (void**)&m_pMyInterface); I thought that this would tell me if the MyInterface is supported m_pMyInterface... ...
I'm doing drag/drop out of an activeX control. On drag, I provide a CComQIPtr which has COM methods implemented to pass information to the drop target. On drop, the drop target's process calls my COM methods to get information. Am I not allowed to use CRT types or pointers to CRT types near that interface boundary? I would love for my I...

I'm working on a .NET library that is intended to be consumed in a VB6 project. To set up the dll to be used on my developer machine, I use regasm and gacutil, like so: regasm /tlb:MyDll.tlb Mydll.dll gacutil /i Mydll.dll On each subsequent call, I also unregister/uninstall the assembly: regasm /u /tlb:MyDll.tlb Mydll.dll regasm ...

I am creating C# application that uses OCX component. I have this component from manufacturer of some kind of printer. During installation of their files, foo.ocx was added to my C:\Windows\System32. The only thing I had to do is add reference in Solution Explorer, and point that library in COM tab. Then I took interface: [Guid("XXX")...
When you have a COM client that exposes an Interface for an out of proc COM server to access, do you have to register the type library or .idl file with the system for the server to be able to access the interface? I'm not sure if I can generate a proxy/stub DLL from this client process to register with the system. Does it matter in wh...

This is a bit of a long shot but does anyone know how to replace the implementation of a COM class at runtime (or, if it is actually possible)? My problem is that we have a COM DLL out there in the wild but we aren't completely sure which version it is and we don't want to have to do a complete rebuild of the software just to replace th...
I have a C++/ATL COM server that implements IConnectionPoint events. My client is a C# application that attaches to the events. When the COM server is created as a SYSTEM service, the client can properly attach to the event. When the COM server is created as a LocalService service (preferred), then I get an E_ACCESSDENIED exception wh...
Hi, I have an EXE COM server (used to elevate our application to a higher integrity level) which is downloaded to %temp% and registered by an ActiveX control. This COM server works pretty well on Vista machines. On Window 7 machines I got something wired: the COM server can be downloaded and registered successfully, but I got the error ...
I know that we can use CoLoadLibrary and DllGetClassObject to get the IClassFactory interface and get the COM component interface without registering the DLL. But what about a COM component in an EXE? Is there a way that I can get a COM component interface from an EXE-type COM server by just providing a different file path? ...
I created a Office Add-In in VS 2008, C#, .NET 3.5, and VSTO. It is deployed via ClickOnce. A run-time configuration form executes regsvr32 to register "fooapi.dll" included with the project that can not be registered during instal due to ClickOnce limitations. Is there any prefered way to check and see if "fooapi.dll" is registered duri...
