Default determining if textbox contains numeric or alphabetic characters


I'm using vb and need to test the contents of a text box to determine if the characters in it are numbers or characters.

for example if my textbox contained "apiuhdiu" I need to ignore it, but if it contained "152.235", I need to be able to use that. do you know how to determine which is in the text box?

If not (text1.text like "*[!a-zA-Z0-9.]*") Then 'anything that's only words or numbers here such as "hi 0.5" 'but no other characters End If If not (text1.text like "*[!a-zA-Z]*") Then 'anything that's only LETTERs here like "thundering" End If If not (text1.text like "*[!0-9.]*") Then 'anything that's only NUMBERS and DECIMALS here like "0.5" End If If not (text1.text like "*[!0-9]*") Then 'anything that's only NUMBERS not DECIMALS like "345287" End If
hope this helps
