print("code sample");I'm a managed codeprint("code sample"); guy, so when I interop with unmanaged code, and it doesn't work as advertised, I get twitchy. Can someone explain to me why this would come back with no MX records, when a command line nslookup works? [DllImport("dnsapi", EntryPoint = "DnsQuery_W", CharSet = CharSet.Unicode, S...
Hello everyone, recently I have been encountering problems with exposing events from .NET to COM.

[ComVisible(false)] public de...

My project requires a background thread to initiate the creation of a WPF control hosted in a Winform. The creation of said control must be performed on the foreground thread, which is very costly and causes the UI to hang for 1 to 2.5 seconds (depending on whether this is the first time the control is created). Are there any pre creat...

Now that there is a new version of the ocx available, I would like force the WinForms app to use newer version. Unregistering the old ocx and registering the new ocx doesn't help. Appreciate any help in achieving the same. ...
I am trying to reference a third party COM DLL from a Visual Studio 2008 project (.NET 3.5 SP1) on Vista Ultimate. I ran the setup for the COM component, and then discovered that it was not the right setup. So I uninstalled and ran the correct install.

The following piece of code shows an Insert table dialog: Dialog d = WordApp.Dialogs[WdWordDialog.wdDialogTableInsertTable]; int result = d.Show(ref missing); if (result == -1) // if user pressed OK { d.Execute(); } The problem is that the dialog does not respond to mouse clicks. It responds to keyboard input, though. Moreover, i...

I have a COM Callable Wrapper that I'm using from a VB6 program, but the program won't receive COM events unless the CCW is registered. Otherwise, the CCW works fine, just no events until I remove the program's manifest file and register the CCW using "regasm /tlb /codebase theccw.dll". This is in WinXP SP3. What could be the problem? ...
I'd like create a kernel(aka named events) from C#. Do I have to interop services and wrap the native CreateEvent function or is there already a .NET class that does the job? The function that I need to run should be something like this: hEvent = CreateEvent ( NULL , false , false , "MyCSHARPEvent" ); This should notify all procs t...

But within J columns every other column has to have formula "=something2". The size ...
