hi guys , girls of stackoverflow community

i have little problem have text box if has numbers in want them not able proceed next form have tried isnumeric works if string numbers come in letter allows user go next page. here have far.

if isnumeric(textbox1.text) messagebox.show("no numbers in name!") else me.hide() frmquestion1.show() end if

so know way create if numbers in string letters in there wont go next form.

this classic regular look validation. seek this:

dim re regex = new regex("\d") if re.ismatch(textbox1.text) messagebox.show("no numbers in name!") else me.hide() frmquestion1.show() end if
