Repeating Numbers

Do anyone have any code that could tell if a series of nine numbers are repeating? I am checking to see if a SSN is all repeating numbers. For example, a person's SSN is 999999999.

Thanks
Shannon

VB Code:

Const TESTDATA = "999999999"
    Dim lngIndex As Long
    Dim bDifferent As Boolean
    
    For lngIndex = 1 To 9
        If Mid$(TESTDATA, lngIndex, 1) <> Left$(TESTDATA, 1) Then
            bDifferent = True
            Exit For
        End If
    Next
    
    If bDifferent Then
        MsgBox "They are not the same"
    Else
        MsgBox "They are the same"
    End If

But it could be any numbers from 0-9. Would you have to create a function for each? I thought about testing positions 1 & 2 to see if they are the same and if they aren't exit the function and if they are test position 2 & 3 and then repeat the process. Would that work?

Thanks

Just convert it to a string, and loop through checking to see if all of the characters are the same.

VB Code:

Private Function IsRepeating(lNumber As Long) As Boolean
 
    Dim lTemp As Long, sTest As String, iCount As Integer
    
    IsRepeating = True
    lTemp = Left$(CStr(lNumber), 1)
    sTest = CStr(lNumber)
    For iCount = 1 To Len(sTest)
        If Mid$(sTest, iCount, 1) <> CStr(lTemp) Then
            IsRepeating = False
            Exit For
        End If
    Next iCount
    
End Function

EDIT: Looks like MartinLiss beat me to it.

I just took what Martin posted, and put it into a Function. Just enter the number string you wish to test in text1.text

VB Code:

Option Explicit
 
Private Function AreNumbersAlike(plngCheckNum As Long) As Boolean
Dim lngIndex As Long
Dim bDifferent As Boolean
    
    For lngIndex = 1 To 9
        If Mid$(plngCheckNum, lngIndex, 1) <> Left$(plngCheckNum, 1) Then
            bDifferent = True
            Exit For
        End If
    Next
AreNumbersAlike = bDifferent
End Function
 
Private Sub Command1_Click()
If AreNumbersAlike(Val(Text1.Text)) Then
   MsgBox "They are different"
Else
   MsgBox "They are all the same"
End If
End Sub

Modify as necessary.

Just glanced over this thread..but if you are checking for valid SSN's to see if someone is just putting in bogus numbers...you could also just check the two center numbers. Aren't they the State? Those numbers could only be fifty different numbers. Sorry if I missed the point.

No that's not true, so it wouldn't work.

VB Code:

dim i as byte
 
for i=1 to 9
   if sSSN = string$(9, cstr(i)) then 
      msgbox "Bogus SSN"
      exit for
   end if 
next i

odamsr, you might wajht to take a look at this thread.
