KB: Group All Command Buttons on a Userform

[Paul_Hossler]

ref: http://www.vbaexpress.com/kb/getarticle.php?kb_id=85


I must be missing something obvious

I can do the example and when I click on one of the buttons I get the message



Private Sub CommandButtonGroup_Click()

MsgBox "You pressed " & CommandButtonGroup.Caption

End Sub




I don't want to show a message, but I'm stuck on how to return which button was Clicked back to the calling program. A Public variable just seems 'not right'

What do you want to do once you know which button has been clicked ? (the checking alternative of a msgbox is debug.print and the immediate window).

Some more background information in:

Normally I would use a property of the form that the calling code can read (though a Public member variable in the form will work too).

Hi All:

Admittedly not well thought through, but I am missing the advantage of a Class for CommandButtons. Leastwise unless we were to be using them as radio buttons (that is, some argument/value would change).

Otherwise, if we are doing different things with each command button - what would be the advantage of instantiating a bunch of classes and figuring out what to do, depending on which button was 'pressed'?

Utterly no offense to Jacob's code - I am just missing it by miles more than Paul :-)

Thank you so much,

Mark

Snoopy Dance! That was my three-thousandth post! (mostly of dubious value...)

Hi Mark,

Nice dancing. ;)

If the buttons all do different things, there would be no advantage to using a class. It would only be useful if they all performed the same action but on say a different range, or were acting as option buttons as you mention.

Or if you want to change some properties, depending on whether it has been clicked .visible.backgroundcolor, enabled etc.

Mostly clumsy dancing, and thank you both :-)

The userform has a 6x7 array of command buttons representing a monthly calendar, or least it will be when I get done

The non-class version has 42 events to return the date associated with the clicked command button, and I was trying to simplify the maintenance

The class version has the 42 command button enteries in a 42 element array. Each command button runs the same event, and I store indentifying information in a class property.

BUT .... I thought I could just use a Property Get to return which command button was clicked, and so far I haven't figure out how

Hi Paul,

I might still be misreading what you are asking, but are you wanting to avoid a Public variable in a Standard Module (to hold the value returned by the button) and would rather store the value in the Form?

Maybe like:

UserForm code:


Option Explicit

Private cButtons(1 To 42) As clsButton

Private lButtonVal As Long

Public Property Let ButtonValue(bv As Long)
lButtonVal = bv
End Property
Public Property Get ButtonValue() As Long
ButtonValue = lButtonVal
End Property

Private Sub CommandButton1_Click()
If Me.ButtonValue > 0 Then
Me.TextBox1.Value = ButtonValue
Else
Me.TextBox1.Value = "No button pushed"
End If
End Sub

Private Sub UserForm_Initialize()
Dim ctl As MSForms.Control
Dim n As Long

n = 0
For Each ctl In Me.Controls
If ctl.Name Like "cmdDAY_##" Then
n = n + 1
Set cButtons(n) = New clsButton
Set cButtons(n).ParentForm = Me
Set cButtons(n).ThisCommandButton = ctl
cButtons(n).ButtonValue = n
End If
Next

End Sub


Class:


Option Explicit

Public WithEvents ThisCommandButton As MSForms.CommandButton

Private objPF As Object
Private lButtonVal As Long

Public Property Set ParentForm(pf As Object)
Set objPF = pf
End Property
Public Property Get ParentForm() As Object
Set ParentForm = objPF
End Property
Public Property Let ButtonValue(bv As Long)
lButtonVal = bv
End Property
Public Property Get ButtonValue() As Long
ButtonValue = lButtonVal
End Property

Private Sub ThisCommandButton_Click()
ParentForm.ButtonValue = Me.ButtonValue
End Sub


Is that anything like what you were wanting?

Hi Mark --

VERY much so!! :thumb

I have a philosophical objection to having a class just throw a value at a global variable

I single stepped through your example (OK, it did take several times) to see the technique and I can integrate it into my little calendar popup

So thanks again :thumb :thumb :beerchug:

:friends: Cheers back and glad that helped :cloud9:
