I'm going to try to keep a running thread about the TechTidBits we talk about during the study group. I hope you enjoy them as much a I do investigating them.
The first TechTidBit we did was talking about
-Breaking the Stack,
-ref: http://www.codeproject.com/useritems/Exception_throw_n_throw.asp
-Tab Order
-taking about the TAB key, viewing/editing the tab order using the Designer
-Smart Tags
-CTRL+.
-App Icons
-using Visual Studio's UI has a sneaky interface for adding multiple icons to an ICO file
-16X16X256 and 32X32X256 are used by Windows in different ways, be safe, have one of each

-Environment.NewLine instead of VBCRLF, "\r\n", 10+ 13, etc
-Path.Combine()
-String.Empty
-String.IsNullOrEmpty() instead of using (YourString.Length == 0 || YourString == null || Your String = "") (or variations there of)
-Windows Vista SnippingTool.exe, AWESOME gem of a tool right within Vista!

-const vs readonly
-const
-Always static
-Evalutated at compile time
-Good for performance
-Initialized at declaration
-Must be integral type (not user defined type)
-readonly
-Both instance scope or static scope
-Evaluated at runtime
-Option to act like constant but set at runtime
-Initialized in declaration or code in constructor
-Can be complex object types with new keyword at initialization
-SQL Server object searches
-complex proc/sql OR
-xSQLSoftware
-http://www.xsqlsoftware.com/Product/Sql_Database_Object_Search.aspx
-Outlining and Regions
-AWESOME way to reduce extaneous code out of the way
