问题 Let dllproject.vbp be a DLL VB6 project. Each time i compile through this Line : VB6.EXE /MAKE dllproject.vbp /outdir somedir The compiler produce a dll with another CLSID. Why ?

问题 I am really stuck in this issue and searching didn't yield me a lot. Most answers I found either get Contacts not add them or use LDAP. The best I've been able to do is display the window where you add people to the distribution list but I am not able to do that part programmatically Here is the my best attempt: Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application(); NameSpace oNS = oApp.GetNamespace("MAPI"); //Get Global Address List.

问题 Is it possible to reference a COM-registered DLL and then create objects that require arguments in the constructor in VBA code? I'm successfully referenced the tlb in Access 2013 (64-bit) that was registered with regasm , and I've managed to create a simple object that doesn't need arguments in the constructor. From what I read, it is not. Do I now face major refactoring? 回答1: It doesn't have to be "major". You simply need a factory method, one that takes all the arguments you need to

问题 I have a base class that is written in C# that implements an interface defined in an IDL library. I have a C++ class that manages the single instance of this class. I also have a C# project that needs to make use of this class [instance (that is obtained through the C++ project)]. I want to cast the COM interface that my base class implements back into my C# base class. However, when I cast the generic object that I acquired from the C++ proportion into my C# base class, I received an error.

问题 I want to use the UpdatePageContent COM method documentation via the python win32com module. Things I can do so far include getting the hierarchy, getting page contents, etc. I can even validly manipulate the XML to prepare changes (tested using the MATLAB COM interface). This is a minimal example of what I am trying to do: import win32com from bs4 import BeautifulSoup oneNoteApp = win32com.client.Dispatch('OneNote.Application') pageID = '{603BD3F0-4DAB-4E5B-8E28-28CA0F2B0C83}{1}{B0}' # from

问题 I have an Excel Add-In that I'm currently trying to set up a unit test framework for. For the unit tests I've followed this guide: http://blogs.msdn.com/b/varsha/archive/2010/08/17/writing-automated-test-cases-for-vsto-application.aspx It seems to work fine, until I want to return a class object from my interface. Specifying the class object as the return type throws a "return argument has an invalid type" exception when calling the method. Changing the return type from the class to an object

问题 I want my inno setup to loop through dlls (both .net and com dlls) in particular folder and register each dll. Is there a way to identify each dll type (.net/com) and use regasm/regsvr depending on the type of the dll. I have a code which loops through .net dlls in a folder and register each one. The code can be found here. In this case, all the dlls were .net type. How to achieve the same with both dlls present in the same folder. 回答1: The following function(s) (originally based on a same
