how do i use for each

if i got a variable MyServer , MyStatus , MyQuitMsg ...
how do i use 'for each' to see if it's NULL ?

When you use the For Each statement, I don't there is a easy way to check variables of different names as the For Each statement will be looping back to the same name everytime, but it can easily be done with variable arrays.

ey... can u give me a sample? cause it's not just 3 variables... i'm trying to check lots of vars..

Code:

---

Private Sub Form_Load()
Dim var(99) As String
Dim i, count As Integer

For i = 0 To 99
    If var(i) = "" Then
        count = count + 1
    End If
Next i

MsgBox count & " variables were empty"
End Sub

---

The code will go through all 100 variables (0 - 99) checking each one to see if it is empty.

'using a collection for storing variables
Public myVar As Collection

Private Sub Form_Load()
    Set myVar = New Collection
    myVar.Add ""
    myVar.Add "Wayne"
    myVar.Add "Jim"
    myVar.Add ""
    myVar.Add "Juillet"
    myVar.Add "Rosie"
End Sub

Private Sub Command1_Click()
'are any of the variables empty
Dim i As Integer
    For i = 1 To myVar.Count
      If myVar(i) = "" Then
      MsgBox "myVar " & i & "= nothing!"
      End If
      Next i
End Sub

Using a collection would a better choice for ease of use, unless you really wanted to use the For Each statement ("how do i use for each"?).
