I am using the sample application calculator that came with VB6.0.

Anyways... In that app, there is one textbox (named Readout)that displays all the numbers being clicked on.  I would like to add another textbox (Readout2).  Then when a number is clicked on, it should be displayed on whichever textbox(Readout or Readout2) that has(had) the focus.


Thanks for your insights...

Why not use 2 grouped OptionButton controls to direct the output to the 2 textboxes, depending which option is selected?

Simple example:

Option Explicit

Dim t As TextBox

Private Sub Command1_Click()
    Static i As Long
    i = i + 1
    t.Text = CStr(i)
End Sub

Private Sub Form_Load()
    Option1.Value = True
    Set t = Readout1
End Sub

Private Sub Option1_Click()
    Set t = Readout1
End Sub

Private Sub Option2_Click()
    Set t = Readout2
End Sub

Private Sub Readout1_Click()
    Option1.Value = True
End Sub

Private Sub Readout2_Click()
    Option2.Value = True
End Sub

Actually,
Readout1_GotFocus(), not Click, works better.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Can't you use Screen.ActiveControl?

Thanks,  That worked!
However,

if i type in "15" in Readout
and then click on readout 2 and type
in 3, it displays in readout2 as "153" instead of 3.

How do I (reset variables?) to make it display 3 when I move to Readout2 (or even Readout3).

thanks

I would have to see your code in order to answer that.  
Is there a string buffer variable which holds the input?  If there is, you need to clear it each time focus shifts from one textbox to another.

This is what I have....

Option Explicit
Dim txtX As TextBox

Private Sub btnNumbers_Click(Index As Integer)
Static i As Long
i = i & btnNumbers(Index).Caption
txtX.Text = i
End Sub

Private Sub txtNewAlarm_GotFocus()
Set txtX = txtNewRun 'This is readout
End Sub

Private Sub txtNewLevel_GotFocus()
Set txtX = txtNewRun 'This is readout2
End Sub


Thanks

Assuming that there are 2 textboxes, and we want to accumulate the captions of each command button to the currently selected textbox use:

Option Explicit
Dim txtX As TextBox

Private Sub btnNumbers_Click(Index As Integer)
txtX.Text = txtX.Text & btnNumbers(Index).Caption
End Sub

Private Sub Form_Load()
Set txtX = txtNewRun1
End Sub

Private Sub txtNewRun1_GotFocus()
Set txtX = txtNewRun1 'This is readout
End Sub

Private Sub txtNewRun2_GotFocus()
Set txtX = txtNewRun2 'This is readout2
End Sub
