After looking here and a few other places for a simple code that allows only numerals and not to allow text to be pasted into a textbox and with no prevail I figured it out. Not a major thing but for beginners this will help them.
VBcoders'Just Paste This in the change section of the textbox sub
Private Sub txtText1_Change()
'if an error should occur go to the error handler
On Error GoTo txtText1_Change_Err
'if the text entered is not numeric
100 If Not IsNumeric(txtText1.Text) Then
'display the message box warning
102 MsgBox "Only Numerals Are Allowed", vbOKOnly + vbExclamation, "Numerals Only"
End If
Exit Sub
'after handling the error and showing what line the error occured in if any
' then resume the next action
txtText1_Change_Err:
MsgBox Err.Description & vbCrLf & _
"in Project1.Form1.txtText1_Change " & _
"at line " & Erl
Resume Next
End Sub
you could easily have the textbox clear out by adding txt.text ="" but that is so basic I figured no need to add it.
Please if theres no code like this and it does indeed help you at least give me a vote for my time sharing this.
