• .NET Development Servers, Pages and their controls and HTTPWebRequest.

  Recently I was asked how to push button on a web page control programmatically and I realized I didn’t know. For the last couple of weeks, I’ve been playing with HTTPWebRequest and getting the samples to work. That’s a wonderful class and it looks as if it exposes every possible thing that could be exposed, but I realized after all the code that I still don’t know how the pieces fit together.   I have a single XP node and I’ve set up ...Show All

Oddly (to me), if I assign a ContextMenu to the MDI form, it comes up fine with a right-click in the form, but it also comes up with a right-click on a MDI child form, unless the child has its own context menu. The problem I have is I create a context menu when the user clicks in a certain area of the MDI form; when that happens, the static MDI ContextMenu is also displayed. If I can detect the MouseDown ( ...Show All

Maybe I just didn't play with it enough. Can we have an optio ...Show All
