Problems with curser movement in control array HELP PLEASE

My assignment says that I can do this through a

"Private Sub txtGrade_LostFocus(Index As Integer)"
procedure... I just don't understand how!



Option Explicit

Private Sub cmdCalculate_Click()
picDisplay.Cls
Call ttlPts
picDisplay.Print "Have a merry vacation."
End Sub

Private Sub cmdExit_Click()
End
End Sub

Private Sub Form_Load()
Dim prompt As String
Dim title As String
Dim i As Integer
Dim Amt As Integer
Dim counter As Integer
picDisplay.AutoRedraw = True
title = "Number of Courses to Average"
prompt = "Enter number of courses to average the grade point"
Amt = InputBox(prompt, title)
i = 0

lblGrade(i).Caption = "Course # " & i + 1 & " Grade"
lblHours(i).Caption = "Credit Hours"
For i = 1 To Amt - 1
Load lblGrade(i)
Load txtGrade(i)
Load lblHours(i)
Load txtHours(i)
lblGrade(i).Top = lblGrade(i - 1).Top + lblGrade(0).Height
txtGrade(i).Top = txtGrade(i - 1).Top + txtGrade(0).Height
lblHours(i).Top = lblHours(i - 1).Top + lblHours(0).Height
txtHours(i).Top = txtHours(i - 1).Top + txtHours(0).Height
lblGrade(i).Visible = True
txtGrade(i).Visible = True
lblHours(i).Visible = True
txtHours(i).Visible = True
lblGrade(i).Caption = "Course #" & i + 1 & " Grade"
lblHours(i).Caption = "Credit Hours"
Next i

End Sub

Public Function GPA() As Single
Dim points As Single
Dim grade As String
Dim TotalPts As Integer
Dim counter As Integer
Dim i As Integer
counter = 0
points = 0
TotalPts = 0
For i = 0 To txtGrade.UBound
grade = UCase(txtGrade(i).Text)
Select Case grade
Case "A", "A+"
points = 4
Case "A-"
points = 3.8

Dim i As Integer

Select Case Index
Case 0


End Select
End Sub

..

nothing

Any suggestions??

You are not helping any body to help you by not explaining what yoy are trying to do. If i remember the last question, which also wasn't explained very well you could do this.

Code:

---

Private Sub txtGrade_LostFocus(Index As Integer)"

  'set the focus to the txtHours with the same index
  txtHours(index).SetFocus

End Sub

Private Sub txtHours_LostFocus(Index As Integer)"

  'make sure that this is not the last control in the array
  If Index < txtGrade.UBound
    'set the focus to txtGrade with the index + 1
    txtGrade(index + 1).SetFocus
  End If

End Sub

just had another idea. you could change your loop to look like this. I assume you have one txtGrade and txtHours on your form already. Set there tabIndex to 1 and 2. (or whatever) Then set myTabIndex to the next number (in this case 3.

Code:

---

Dim myTabIndex as Integer

myTabIndex = 3

For i = 1 To Amt - 1
  Load lblGrade(i)
  Load txtGrade(i)
  Load lblHours(i)
  Load txtHours(i)
  lblGrade(i).Top = lblGrade(i - 1).Top + lblGrade(0).Height
  txtGrade(i).Top = txtGrade(i - 1).Top + txtGrade(0).Height
  lblHours(i).Top = lblHours(i - 1).Top + lblHours(0).Height
  txtHours(i).Top = txtHours(i - 1).Top + txtHours(0).Height
  lblGrade(i).Visible = True
  txtGrade(i).Visible = True
  lblHours(i).Visible = True
  txtHours(i).Visible = True
  lblGrade(i).Caption = "Course #" & i + 1 & " Grade"
  lblHours(i).Caption = "Credit Hours"
 
  'set the tab index's
  txtGrade(i).TabIndex = myTabIndex
  myTabIndex = myTabIndex + 1
  txtHours(i).TabIndex = myTabIndex
  myTabIndex = myTabIndex + 1

Next i

---

You are correct in assuming I already have two txtBoxes on the form.
I have tried both options -
If I use the myTabIndex then the curser automatically appears at the last txtBox.
So I added it to a select case procedure - it just doesn't work. (see below)
Private Sub txtGrade_GotFocus(Index As Integer)
Dim myTabIndex As Integer, i As Integer
Select Case Index
Case 0
myTabIndex = 0
txtGrade(i).TabIndex = myTabIndex
myTabIndex = myTabIndex + 1
txtHours(i).TabIndex = myTabIndex
myTabIndex = myTabIndex + 1
Case 1
myTabIndex = 2
txtGrade(i).TabIndex = myTabIndex
myTabIndex = myTabIndex + 1
txtHours(i).TabIndex = myTabIndex
myTabIndex = myTabIndex + 1
Case 3
myTabIndex = 4
txtGrade(i).TabIndex = myTabIndex
myTabIndex = myTabIndex + 1
txtHours(i).TabIndex = myTabIndex
myTabIndex = myTabIndex + 1
Case 4
myTabIndex = 6
txtGrade(i).TabIndex = myTabIndex
myTabIndex = myTabIndex + 1
txtHours(i).TabIndex = myTabIndex
myTabIndex = myTabIndex + 1
Case 5
myTabIndex = 8
txtGrade(i).TabIndex = myTabIndex
myTabIndex = myTabIndex + 1
txtHours(i).TabIndex = myTabIndex
myTabIndex = myTabIndex + 1
End Select
End Sub

If I use the LostFocus Sub
I keep getting errors.

I'm almost ready to give up.

You still haven't explained exactly what you want to achieve, but here is another attempt.

When the form loads up the cursor will be in txtHours(0). Then when you tab the cursor will move to txtGrade(0), then txtHours(1) then txtGrade(1) etc.


set the TabIndex of txtHours(0) = 0
set the TabIndex of txtGrade(0) = 1

now use the following code.

Code:

---

Option Explicit


Private Sub cmdCalculate_Click()
    picDisplay.Cls
    Call ttlPts
    picDisplay.Print "Have a merry vacation."
End Sub

Private Sub cmdExit_Click()
    End
End Sub

Private Sub Form_Load()
    Dim prompt As String
    Dim title As String
    Dim i As Integer
    Dim Amt As Integer
    Dim counter As Integer
    Dim myTabIndex As Integer

    myTabIndex = 2
 
    picDisplay.AutoRedraw = True
    title = "Number of Courses to Average"
    prompt = "Enter number of courses to average the grade point"
    Amt = InputBox(prompt, title)
    i = 0
 
    lblGrade(i).Caption = "Course # " & i + 1 & " Grade"
    lblHours(i).Caption = "Credit Hours"
    For i = 1 To Amt - 1
      Load lblGrade(i)
      Load txtGrade(i)
      Load lblHours(i)
      Load txtHours(i)
      lblGrade(i).Top = lblGrade(i - 1).Top + lblGrade(0).Height + 20
      txtGrade(i).Top = txtGrade(i - 1).Top + txtGrade(0).Height + 20
      lblHours(i).Top = lblHours(i - 1).Top + lblHours(0).Height + 20
      txtHours(i).Top = txtHours(i - 1).Top + txtHours(0).Height + 20
      lblGrade(i).Visible = True
      txtGrade(i).Visible = True
      lblHours(i).Visible = True
      txtHours(i).Visible = True
      lblGrade(i).Caption = "Course #" & i + 1 & " Grade"
      lblHours(i).Caption = "Credit Hours"
     
      txtHours(i).TabIndex = myTabIndex
      myTabIndex = myTabIndex + 1
      txtGrade(i).TabIndex = myTabIndex
      myTabIndex = myTabIndex + 1
   
    Next i

End Sub

Public Function GPA() As Single
    Dim points As Single
    Dim grade As String
    Dim TotalPts As Integer
    Dim counter As Integer
    Dim i As Integer
   
    counter = 0
    points = 0

      End Select

By changing the myTabIndex=2
we (YOU) have it going!

For not knowing what I was asking, you certainly did show me the solution.

I have been pulling my hair out!! I had tried multiple versions of what you later suggested, but couldn't get it to go!

Life is good again.
