VB Dialog Controls
« on: March 29, 2009, 12:04:00 PM »
I'm screwing around with VB and dialogs, but can't seem to get reading and writing TextBox controls to work.  My code is below.  It appears to me I *should* be able to write to the TextBox control with:

        Dlg1.VFDFreq = "abcd"  or, perhaps Dlg1.VFDFreq.Text = "abcd"

Both throw syntax errors.  What am I doing wrong?

Sub Main

   Begin Dialog BoxSample 16,35,256,89,"Motor Speed Calculator", .OnAction

      CancelButton 204,44,40,14
      Text         12,12,64,8,"Target Speed:"
      TextBox      16,24,32,10,        .TargetSpeed
      Text         130,12,  50, 8,"VFDFreq:"
      TextBox      130, 24, 50, 10,    .VFDFreq
   End Dialog

   Dim Dlg1 As BoxSample
   Button = Dialog ( Dlg1 )

End Sub

Function OnAction( ControlID$, Action%, SuppValue% )


   Select Case Action%

   Case 1

   Case 2
      If ControlID$ = "TargetSpeed" Then
         Dlg1.VFDFreq.Text = "1234"
      End If
   Case Else
   End Select
End Function

Hmmmmm....  This is interesting as well.  The Cypress documentation says Action 3 does:

"Action 3 Corresponds to a change in a text box or combo box. This value is passed when a control loses the focus (for example, when the user presses the TAB key to move to a different control) or after the user clicks an item in the list of a combo box (an Action value of 2 is passed first). Note that if the contents of the text box or combo box do not change, an Action value of 3 is not passed."

But, Action 3 actually occurs on *every* keystroke entered into a TextBox....

OK, I seem to be able to set control values with DlgText, and it looks like DlgValue should get a controls value, but all I can read is zeroes....
