Visual Basic 2010 Express Tutorials - Tutorial 6 - Data Parsing Error Checking and An User Friendly Interface

Notes:

Data Parsing is more powerful than using VAL() STR(). The code for parsing is  the datatype.parse

Examples

Integer.Parse

Single.Parse

Double.Parse

Error Handling:

Try

Catch

End Try

When there is an error, like typing “A” when a integer is expected will cause an error. The error is caught and the code within Catch is run.
