If ModuloCtls.ctlText has the CaptionBackColor property then the above should compile. What errors are you receiving? Can you post the code of the ModuloCtls.ctlText class? Is the CaptionBackColor public?

Hi dgb,
Try my attached code.

Good Luck

Public Sub SetColor(ByVal obj As Control)
Dim currentControl As Control
Dim curObject As Object
For Each currentControl In obj.Controls
If TypeOf currentControl Is ModuloCtls.ctlText Then
Dim current As ModuloCtls.ctlText = CType(currentControl, ModuloCtls.ctlText)
            curObject = currentControl
            curObject.CaptionBackColor = Color.GreenYellow   
End If
 Next
End Sub

Oh I see the problem, you are not using "current" which I'm guessing is the control that has the CaptionBackColor property, so change your code to look like this:

Public Sub SetColor(ByVal obj As Control)
Dim currentControl As Control
Dim curObject As Object
For Each currentControl In obj.Controls
   Select Case TypeName(currentControl)
       Case "ctlText"
            Dim current As ModuloCtls.ctlText = CType(currentControl, ModuloCtls.ctlText)
            curObject = currentControl
            current.CaptionBackColor = Color.GreenYellow      
       End Select
Next
End Sub

Try this:

Private Sub Form_Load()
   SetColor Me
End Sub
 
Public Sub SetColor(frm As Form)
   Dim ctl   As Control
   On Error Resume Next
   For Each ctl In frm.Controls
      ctl.CaptionBackColor = Color.GreenYellow
   Next
End Sub

Sorry,
I thought that I already accept the answers yesterday.
It was an error somewhere else in the software. But both solutions do the job.
