• Windows Forms Raising a (keyboard) event programatically

  I'd like to be able to raise a keyboard event from within my code. That is, when a user presses 'a' in a textbox, it triggers a series of events (KeyDown, KeyPress etc) and I'd like to be able to do the same thing from my code. It seems like a pretty common thing to do and I thought I'd found the right function when I found the Control.RaiseKeyEvent() function. Unfortunately, not only can I not get it to work, but there doesn't seem to ...Show All

• Visual C# Logger in multi-threaded application

  Hi, I have a multithreaded application, in which most my classes inherit from a base class. This base class contains a Log()-method, that is supposed to append text to a text box created in the main thread. I know that this is a problem since I can/should only access the textbox in the same thread as where it was created.

  Is it possible to use a WebService as the datasource for a listobject in a managed excel workbook Most samples are using datasets.
