>>>When I ran your sample for the first time, I did get a shock. After careful examination, I found that you did not specify a DataType for the StringBuilder in the VB .NET code. Here is my VB .NET and C# test code and results. Notice that the results are the same in VB .NET and C#.
ahhh... you got it... as I told since the beginning, I´m studying C#, and didn´t know too much about VB.NET....
Thanks A LOT for taking your time, Kamal.
