createobject

问题 In my company's code, I've often seen component files used by initializing an object of that component and calling the methods off the object. However, it seems to me somewhat more straightforward to use the cfinvoke method, especially when only using one method from the component file. What are the differences between these 2 methods of calling a component function and what are the pros/cons of each? When should I use which? 回答1: cfinvoke can only be used in tags. createObject can be used in

问题 I have a COM object that I am trying to wrap in a C# class in order to make it more readily available for other applications that wish to consume it. I have the following code that creates an instance of the COM object, and then using reflection makes a call to a method to retrieve user data. This code works fine when it is located in an aspx page. object jdObj = Server.CreateObject("jd_api.UserCookie"); string username = jdObj.GetType().InvokeMember("GetUserName", System.Reflection

问题 We need to figure out how a service can peek at a running VB6 app and/or its DCOM spawned exe and figure out which VB6 app goes with which DCOM exe. The VB6 app and the spawned exe are both on the same server. We have a VB6 app that spawns an instance of Bartender (from Seagull Scientific) by way of a CreateObject() call. On a given server, we may have ten or twenty instances of our app, each represents a handheld RF gun client in a warehouse. 95% or more of these VB6 apps will have their own

问题 Is there a way to determine if a registered COM component is creatable as a stand-alone component simply by parsing the information available in the registry? In particular, by the information found in HKCR/ClsId? My system has over 12,000 entries in this key, and I am already excluding any items that do not have an InProcServer32 or LocalServer32 key, but this only eliminates about half of the items. I believe there are still another couple thousand that are not creatable objects. I really

问题 Hey all this is my first time creating a COM object for a classic asp page. The process I followed when creating this COM DLL is this: 1) Used the Strong Name Tool (sn.exe) and placed the .snk file within the app. (sn -k myKey.snk) 2) Added: [assembly: AssemblyKeyFile(@"myKey.snk")] [assembly: ComVisible(true)] to the AssemblyInfo.cs. I do get a warning on the KeyFile saying: Use command line option '/keyfile' or appropriate project settings instead of 'AssemblyKeyFile' 3) Ran the following

问题 In Visual Basic.net, can I create an Object, or a List of T with the type from another object. Here is some code: Dim TestObjectType As Author Dim TestObject As TestObjectType.GetType I am getting an error: TestObjectType.GetType is not defined EDIT Can I create a Type object of a certain type, and then create objects, lists or cast objects to this type from this Type object? 回答1: Dim TestObject As TestObjectType.GetType will look for a type named GetType in the namespace TestObjectType . To

问题 I can do this: Dim fso As New FileSystemObject or I can do this: Dim fso As Object Set fso = CreateObject("Scripting.FileSystemObject") How do I know what string to use for CreateObject? For example, how would I know to use the "Scripting." part of "Scripting.FileSystemObject"? Where do you go to look that up? 回答1: It is the ProgID of the component which is registered in Windows registry under HKCR key: HKEY_CLASSES_ROOT\Scripting.FileSystemObject ProgID's are human readable identifiers for
