问题 I'm running a form in a second thread. If I do Ctrl-C to copy text on the clipboard, I get an Exception, "Current thread must be set to a single thread apartment (STA) before OLE calls can be made. (Using the clipboard involves OLE apparently). Putting the [STAThread] with my thread proc, which is the entry point of my second thread does NOT work. What will work? [STAThread] private void MyFormThreadproc(object o) { form = new MyForm(); Application.Run(form); } 回答1: When you create the thread

问题 I'm working on a out of browser Silverlight app that provides some MS Office Communicator 2007 controls. I'm using the Automation SDK. The docs that were installed with the SDK state that there's a MyGroups property in the IMessenger2 interface, which will return the groups that a user has defined, but when I try to use it, I get a NotImplementedException . Here's the code that I'm using: dynamic communicator = AutomationFactory.CreateObject("Communicator.UIAutomation"); communicator

问题 Basically, when i use vb.net or c#.net to do this, it works perfectly, but when i use vb6, it doesn't work, in my for loop where the relevant service in the relevant device is captured, here is the code that returns no result... ' serv is properly declared and instantiated by the for loop. Dim xins(0) Dim xouts(0) MsgBox ("Starting..." & serv.ServiceTypeIdentifier & vbCrLf & serv.id & vbCrLf & serv.LastTransportStatus) ' all this shows correctly. serv.InvokeAction "GetExternalIPAddress", xins

问题 tlb file(using regasm) is made from a dll(using c# code), and i can use this in c++ using #import. and everything is working fine. Is there a way, i can use this in C language? I just found that #import is c++ specific. So, can someone please tell me how can i use in my C program? my main intention is to use COM DLL developed in C# in my C program. Thanks & Rgds, ~calvin 回答1: COM programming in C is very painful, but not impossible. The buck stops here though. The point of a type library is

问题 I need to check whether a file (with unknown extension) is a valid SQLite database. My function works fine, but when it fails, the file is still locked after exiting the function: Public Function IsSqliteDB(ByVal uPath As String) As Boolean 'Workaround for my problem: Make a copy and work on this because this function is going to lock the file unfortunately Dim sNewPath As String sNewPath = Settings.Locations.Folder_LocalAppData_Temp & "\temp_" & Replace(Now.ToString, ":", "_") & ".db" modIO

问题 I have looked at tutorials on jscript arrays, but not seeing it yet. I saw something similar asked but involving Win32 code not .NET. Wondering, how do I pass arrays back and forth between JScript and a C# COM component? For example, I have two properties defined in my C# COM that returns string and integer arrays as: string[] HeaderLines { get; set; } int[] ImagePixels { get; set; } In my test.js file: ... var T = new ActiveXObject("Imager.Reader"); ... var headerLines = T.HeaderLines;

问题 I'm using some PowerShell functions to configure Windows product keys and activation. I get an instance of the SoftwareLicensingService and call InstallProductKey, like this. The trap block with super formatting is extra to help debugging. trap [Exception] { "==================================================" "Trapped: $($Error[0])" "==================================================" "Exception: $($_.Exception)" "--------------------------------------------------" "" break } $service = Get

问题 I'm working through "Developer's Workshop to COM and ATL 3.0" by Andrew W. Troelsen. I'm trying to implement the lab in Chapter 3. It shows you how to build a COM client to connect to an inprocess COM server that was developed in an earlier lab. When I run the client, I receive the error "Class not registered" when calling 'CoGetClassObject'. Here is a snippet of code: // Get the class factory pointer of CoCar. hr = CoGetClassObject(CLSID_CoCar, CLSCTX_INPROC_SERVER, NULL, IID_IClassFactory,
