• .NET Development VBScript

  Hello, I have been using the VBScript language trough the scriping runtime engine. I would like to know if I can upgrade to some other scripting language which works with .net instead of COM. Thanks. Hello Ori, Yes, there are a number of scripting languages which have been ported to the .NET Framework/Common Language Runtime.

• Visual C# Is C# the best language to learn/know?

  Hello, I am currently studying C#.  I presumed that C# is much better than VB.NET and so started studying it.  But it seems to me that most everyone related to microsoft is always pushing for VB.NET and not having much to say about C#, so what is going on   Id Est; - I now regularly catch the Dot NET Rocks radio show, which seems to be based, or at least biased toward VB.NET.  - I stumbled upon the VB.NET PDC05 disk online at http://msdn.microsoft.com/vbasic/pdc05/default.aspx which I was quite impressed with, so I thought I'd find the C# equivalent, to no avail.  Please let me know if there is one availa ...Show All

• .NET Development WSE3 doesn't work in VS2005 (add-in not installed and proxy not generated correctly)

  Hi all, I've got a lot of problem using WSE3 with my installation of VS2005 Team Suite.

I can bypass the problem using manually the Configuration tool to edit the configuration files. But I've also another problem: this happens both with my application and with the quickstart examples: when I add a web reference, the generated proxy is still the old one (which inerhits from SoapHttpClientProtocol) and not the "new one" that should inherits from Microsoft.Web.Services3.WebServicesClientProtocol and should have ...Show All

• Windows Forms bound controls not committed when selecting the menu bar

  Hello, I have a question in regards to binding controls (ie. TextBox). I noticed that any value in the control does not update the object it is bound to until that control loses focus. This normaly works quite well, except the following scenario: Suppose there is an app w/ a textbox, and a save option in the menu. If a user edits a new text string into the textbox, and clicks on the menu to select the save option, the textbox still has focus and that string will not get updated into the object the control is bound to. So, if the user continues to select the save option in the menu, the text string will not get serialized out like it is ...Show All
