Hi,

I want to prevent the user to type some characters. The * and ?

Is it possible with Setmask ? Prefer a (working) sample how to do this.

Thank you very much!!

Hi,

Sorry no. Seems we need add regexp support for future :( Quite a lot of requests.

Hi Oleg,

Regex would be cool, but it might be easier to implement a BeforeEditInsert event that allows us to cancel any changes before they happen. This would allow us to easily allow/disallow keypresses for any reason.

Something like


Private Sub BeforeEditInsert(NewText As String, Cancel As Boolean)
    If Instr(1, NewText, "*") Then
        ' Remove * characters from string to be inserted into item
        NewText = Replace$(NewText, "*", "")
    End If

     If IsNumeric(NewText) Then
           ' Do not allow numeric strings to be inserted into item
            Cancel = True
    End If
End Sub

In the above example, any * characters about to be inserted into the item edit box would be removed, then if the text to be inserted was numeric, then the insertion would be completely cancelled. This is a nonsense example, but it illustrates two features:

1) Ability to modify the insertion text instead of cancel it completely
2) Ability to cancel the insertion of text completely.

Maybe not as powerful as regex support, but it should be easier to implement as an interim solution (NOTE: by passing NewText as a string, it makes it possible to handle Pasted text as well as single key presses).

In AfterEdit-Event you have the NewValue you can change or in ValueChanged-Event you can change the Item.Value-Property.

Hi,

Yes, thanks. I did some workaround in the value changed event.

It's unbelievable that we have to do it like this. We have setmask and key events and both options are useless.
