Class module to filter textbox entry

[Shawn]

To all

I have a module I am trying to use to filter the data entry of all textbox's
so as only to allow integers. I can do it by entering all the textbox
numbers by hand etc.. but was hoping to filter based on the class module.

Below is the code but am stuck as to how to pass the text box name to the
module

AHGA!!

' class module called CTBX

Public WithEvents TextCtrl As MSForms.TextBox

Private Sub TextCtrl_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)

Call UserForm4.CheckKeyPress(TextCtrl.Name, KeyAscii, True, False)

End Sub

' userform initialization on my form!

Private Sub UserForm_Initialize()
Dim Ctrl As MSForms.Control
Set Coll = New Collection
For Each Ctrl In Me.Controls
If TypeOf Ctrl Is MSForms.TextBox Then
Set TBX = New ctbx
Set TBX.TextCtrl = Ctrl
Coll.Add TBX
End If
Next Ctrl
End Sub

PUBLIC SUB TO FILTER THE INPUT

Public Sub CheckKeyPress(tb As MSForms.TextBox, _
ByVal KeyAscii As MSForms.ReturnInteger, _
Optional ignoreDecimal As Boolean, _
Optional allowNegative As Boolean)

Dim key As String
Dim pos As Integer
Dim selLength As Integer
If KeyAscii <> 127 Then

key = Chr(KeyAscii)

' If it is not a number (0 thru 9)...

If Not IsNumeric(key) Then

pos = tb.SelStart
selLength = tb.selLength

If (key = decimalSep And Not ignoreDecimal) _
Or (key = "-" And allowNegative _
And pos = 0) Then
If Not ((InStr(tb, key) = 0) Or (selLength > 0 _
And InStr(tb.SelText, key) > 0)) Then
KeyAscii = 0
End If
Else
KeyAscii = 0
End If
End If
End If
End Sub

I found a solution that works, I just placed the public function inside the
class module and it worked fine!

Thanks for being a sounding board

Private Sub TextCtrl_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)

Call UserForm4.CheckKeyPress(TextCtrl, KeyAscii, True, False)

End Sub


worked for me.

Thanks for the quick reply, I found a kludge work around but the version
you show is more elegant (If I can get it to work)

I tried it as you typed it and no go.... got a "method or data member not
found" error.

Not sure why it worked for you and not for me, need to play with it longer

Anyway any other help would be appreciated!

I also declared

Dim Coll as Collection

at the top of the userform module outside any procedure.

Other than that, I don't recall altering your code.

I tried that as well (also in the declare field of a module so it is
available everywhere.. but)

Not sure why mine isn't working. What are you using for your excel??

Just made a simple userform with 3 textboxes.

Then made the class module called ctbx

as follows...

Public WithEvents TextCtrl As MSForms.TextBox


Private Sub TextCtrl_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)

Call UserForm1.CheckKeyPress(TextCtrl, KeyAscii, True, False)

End Sub


USERFORM1 code as follows:

Dim coll As Collection
Private Sub UserForm_Initialize()
Dim Ctrl As MSForms.Control
Set coll = New Collection
For Each Ctrl In Me.Controls
If TypeOf Ctrl Is MSForms.TextBox Then
Set TBX = New ctbx
Set TBX.TextCtrl = Ctrl
coll.Add TBX
End If
Next Ctrl
End Sub
Private Sub CheckKeyPress(tb As MSForms.TextBox, _
ByVal KeyAscii As MSForms.ReturnInteger, _
Optional ignoreDecimal As Boolean, _
Optional allowNegative As Boolean)

Dim key As String
Dim pos As Integer
Dim selLength As Integer
If KeyAscii <> 127 Then
key = Chr(KeyAscii)
If Not IsNumeric(key) Then
pos = tb.SelStart
selLength = tb.selLength
If (key = decimalSep And Not ignoreDecimal) _
Or (key = "-" And allowNegative _
And pos = 0) Then
If Not ((InStr(tb, key) = 0) Or (selLength > 0 _
And InStr(tb.SelText, key) > 0)) Then
KeyAscii = 0
End If
Else
KeyAscii = 0
End If
End If
End If
End Sub

Still get error, any other idea's??

Private Sub CheckKeyPress(tb As MSForms.TextBox, _

should be

Public Sub CheckKeyPress(tb As MSForms.TextBox, _

Tom

Thanks, that did it!

Private Sub CheckKeyPress(tb As MSForms.TextBox, _

should be
