Simple one to start, how to convert a string to an integer...
in C# use the following code:
integerOne = Convert.ToInt32(stringOne);
and in VB.NET :
Dim stringOne as string = nothing
Dim integerOne as integer = nothing
stringOne = "10"
integerOne = Convert.ToInt32(stringOne)
and a little update today to include PHP :
$aString = "10";
$aNumber= (int)$aString ;
Hope this helps someone out there...keep tuned for more coming soon.
