• Visual C# Interesting little bug

  Okay I've come across a bug that im not sure how to solve: I have a custom Control called IrcChannelBox , which contains a RichTextBox in it (called chatbox).

• SQL Server Programmatically loop over variables in the variable dispenser?

  In my custom task, I would like to loop over the variables in the variable dispenser, and only modify those that are of a certain type. Is this possible Thanks! I think you can use Me.variables(x).getType to get the type of each variable. If that is not correct, you can define variables name sXXX for string, iXXX for integer, etc. Then parse the variable name, get the first character and determine the variabl ...Show All

I have not been able to pinpoint the exact sequence of events to consistently reproduce ...Show All
