Take a look at the validator controls. You can validate that the textbox is
non-empty, has a number in it and you can even validate that the number be
within a particular range of values.

It's not just a simple string. You should spend a little time reading about
the Validation controls, otherwise any "validation string" won't help you.
Do you need a pointer to the MSDN documentation on the validation controls?

Take a look at the validator controls. You can validate that the textbox
is
non-empty, has a number in it and you can even validate that the number

that might help. I have another related question, I defined myVar as double
and it seems myVar=myTextBox.Text statement converts text to double without
problem. Do you see any problem in that?

Yes. Don't let VB.NET do such things for you. Turn "Options Strict On", and
decide for yourself what the relationship is between text and string.
I suggest that Options Strict be turned on always except possibly at the
very beginning of a migration from ASP.
