How would i enable a command button after 3 or 4 text boxes have been filled in.  I want the user to fill the text boxes in with the info and once ALL the text boxes are filled in i then want the command button to become enabled so they can move onto the next area???
I am using VB6.

Cheers

    JUst run a check procedure in the lost focus or keypress event of the text boxes

    ie:

    sub textbox1_lostfocus()
      checkValadation()
    end sub

    ...

    sub checkValadation()
      if (len(textbox1.text ) > 0 ) then
        if (len(textbox2.text ) > 0 ) then
          if (len(textbox3.text ) > 0 ) then
            cmdOk.enabled = true
          end if
        end if
      end if
    end sub

    or if you want instant effect, you can try put the validation code to the Changed event instead. like:

    Private Sub Text1_Change()
        chkEnable
    End Sub

    Private Sub Text2_Change()
        chkEnable
    End Sub

    Private Sub Text3_Change()
        chkEnable
    End Sub

    Private Sub Text4_Change()
        chkEnable
    End Sub

    Private Sub chkEnable()
        Command1.Enabled = IIf(Len(Text1) > 0 And Len(Text2) > 0 And Len(Text3) > 0 And Len(Text4) > 0, True, False)
    End Sub
