Trying to understand What is IConnectionPoint and how this is connected to IConnectionPointContainer,IEnumConnectionPoints,IEnumConnections and EventHandling . Read the artcicles from MSDN and CodeProject which is explaining a about other methods like: QueryInterface() and otherthings. I am unable to figure out how all these things( IConnectionPointContainer,IEnumConnectionPoints,IEnumConnections ) are interconnected with eachother and event Handling. I just want to create a simpleClient which Will trigger an event in COM object. If there are any articles or code snippet that can explain how

Is the iTunes COM interface available on Mac OS/X? From the documentation I could find, it seems much more extensive than the Applescript interface I could expose through the Automator program. Disclaimer : absolute OS/X newbie here. The COM interface is windows-only. For seeing what Applescript capabilities an application like iTunes has, you probably want to use the low-level AppleScript Editor utility, instead of Automator . The Open Dictionary... menu command in AppleScript Editor lets you open any scriptable application and see what objects & commands it supports. There's also a large

Edit : I know that C# equivalent of For Each server As String In servers is foreach(var item in servers) but since GetOPCServers returns object, it should be cast to iterable type. I am developing an application using a COM library. Since 64bit causes problems, my target CPU x86. All methods works as expected, except GetOPCServers() . Although Visual Basic code using same dll does not cause problem, C# throws System.InvalidCastException saying that: A first chance exception of type 'System.InvalidCastException' occurred in System.Core.dll Additional information: 'System.String[*]' türündeki

I've got a registered ActiveX component which I'm referencing in a C# project. However, I'd like to know the original path to the actual component being run. This is not the execution path per se. Is there something saner than searching the registry by hand? The component is registered with a simple /regserver command, if that's relevant. Andrey Search under the HKEY_CLASSES_ROOT\CLSID with the name of your EXE file. It should be used as value of "LocalServer32". Here's a function that fetches the value out of the Registry. Extra validation required. using Microsoft.Win32; //... static string

I don't know how to debug a COM ATL C++ out of process exe server with Visual Studio 2015. For a COM ATL DLL there is no problem, the breakpoints are automatically triggered when I call the COM dll. However when I try to debug an EXE server, the debugger didn't break. Indeed the exe server is only loaded at demand and the debug symbols of the exe server are not loaded when the client starts. My client, that call the COM server, is Excel VBA (I have added the reference to the com exe, in the VBA editor, via Tools/References). To debug it, I set the path to Excel.exe in the Visual Studio Debug

I have a pointer to a COM interface and would like to take the function pointers from its virtual table and make method calls. To do this I need to make stdcall method calls. In Go how do I make a call with convention stdcall or make a call with convention stdcall in cgo? See "godoc syscall Proc" for instructions on how to call stdcall functions on windows. Be warned that *Proc.Call does allocate / deallocate memory, so, if you care about efficiency, you should use correspondent syscall.Syscall/syscall.Syscall6/syscall.Syscall9/... function instead.

I am working on a .NET program that starts a new instance of Excel, does some work, then ends, but must leave Excel running. Later, when the program runs again, it will attempt to hook into the previous instance. What is the best way to handle the releasing of COM objects in this situation? If I do not do a "ReleaseComObject" on the app object the first time, then on the second run get the active object, then finally release the com object, do I have a memory leak? The following simplified code illustrates what I am trying to do: private Microsoft.Office.Interop.Excel.Application xlsApp;
