问题 The entry for "Microsoft Excel Application" is not there in DCOM Config (tried in both 32-bit and 64-bit). How can I make it shows up there? I have Microsoft Office installed. 回答1: If you cannot find 'Microsoft Excel Application' in either 32-bit or 64-bit DCOMCNFG, you might go into registry to HKEY_CLASSES_ROOT/AppID and find the CLSID for your version of Excel (Excel 2013 has an AppID of {00020812-0000-0000-C000-000000000046}) Check that the (Default) REG_SZ for this key has a value set

问题 Context : I'm working with some old robotics software which is able to get information from a COM object if it implements some predefined interfaces. Since this old software runs on Windows 2000, I want to use DCOM to (try to) avoid having to compile something for Windows 2000. (I am aware that the program that has to be called probably needs to work, or at least exist, on the Windows 2000 computer as well) The other computer will be called through DCOM and will process an image using a

问题 My D5 application is on a server being used remotely by a couple of users, so I need use the following function to create a COM object to launch another application (LmPos) installed back on that users PC upon launch: CreateRemoteComObject(const MachineName: WideString; const ClassID: TGUID): IUnknown; rather than creating a local COM object as before: EposServer := CreateOLEObject('POS.Server'); However, the MachineName and ClassID to connect to will depend on which users is launching this

问题 We have a scenario where some .NET code is attempting to access the current instance of a COM (actually DCOM) object. The object being accessed was developed in VB6. A current instance of it is available on the remote system, and appears to be accessed correctly from VB6 code. Attempting to call Marshal.GetActiveObject , specifying the class name, causes a COMException to be thrown, referencing error 800401E3 (Operation Unavailable). The same .NET code appears to operate correctly when run on

问题 I have an old Win32 C++ DCOM Server that I am rewriting to use C# .NET 3.5. The client applications sit on remote Windows XP machines and are also written in C++. These clients must remain unchanged, hence I must implement the interfaces on new .NET objects. This has been done, and is working successfully regarding the implementation of the interfaces, and all of the calls are correctly being made from the old clients to the new .NET objects. However, I'm having problems obtaining the

问题 I have a desktop application that will be used on computers with no keyboard, input will be on a touch screen.

问题 I have read through all the similar questions but am not finding my exact problem answered. I have tried all the similar recommendations. I am forced to migrate from a Windows Server 2003 environment to a Windows Server 2008 R2 environment running IIS 7.5. I have a web application that calls COM objects in a 32-bit DLL. The COM object was created from VB6. Here is what I have done to date: I have enabled 32-bit on my IIS Application Pool. I have registered the .DLL and it's dependent .DLL
