input mask

[citizenstitch]

how do you make input masks for things like phone numbers and social security numbers?

[<ABX]

you could use regular expressions http://www.regular-expressions.info/tutorial.html

Here is one for a email address \b[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}\b

Matching Vaild dates 19|20)\d\d[- /.](0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])

usage example

Dim x as New System.Text.RegularExpressions.RegEx("\b[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}\b)
 
Msgbox(x.Match("[email protected]"))
Msgbox(x.Match("aInvaildEmail2woot.ca"))

how do i make this check a textbox? great post by the way. it took me awhile to understand the code but the website helped.

[<ABX]

Dim x as New System.Text.RegularExpressions.RegEx("\b[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}\b")  
 
If x.Match(TextBox1.Text) Then
    Msgbox("Vaild Email!")
Else
    Msgbox("Invaild Email!")
End if

it underlines x.Match(TextBox1.Text) and says it can not be converted to boolean
