I'm automating some outlook functionality in a .NET app. It works great. I am compiling it and using v 12.0.0.0 of the Outlook Interop assembly.

From the documentation: The CTypeDynamic method applies dynamic conversions in accordance with the conversion semantics defined by the object itself. If a dynamic object inherits from DynamicObject, the CTypeDynamic method first attempts to perform the conversion by using a user-defined, static conversion. If the user-defined, static...
I'm trying to convert some functions written in JScript to VB.NET (I'm porting a classic ASP page to ASP.NET) and having issues as I'm not very familiar with JScript.

I have recently begun working at a company wherein there are very few (2-3) programmers and many more engineers. As a result, the default language of choice has become VB.net. I look at some of the math-intensive portions of the programs that have been written thus far and I'm certain that these portions could be improved considerably if...

I'm trying to write out animals from a database. All the samples I see for creating View pages have hard-coded "nodes" in the URLs. I can get my first view to work but my second one doesn't write out the correct URL to go to the third one. So, for example, I want my URLs to be: /animals/ /animals/canines/ /animals/canines/schnauze...
