Increase Numbers containing letters.

I have a registration routine
the credit card company that processes purchases needs a list of valid unlocking numbers.
each time a purchase is made the user is given the next unlocking number
I want to give them a list of 100 valid numbers are between 5000 and 9900
a valid entry could be yjk50kg00dky
with the number subtracted from the string it would be 5000
The next valid number would be yjk50kg01dky the nummbers in the string = 5001
the next 5002
the next 5003
all the way to a hundred.
the string would stay the same "yjkkgdky"

every number would be incremeted by 1
How to write this ?

OK given a starting value, this will print out the next 100.

Sub test()
OutPutRegistractionNumbers "yjk50kg01dky"

End Sub

Public Sub OutPutRegistractionNumbers(strStartingValue)
Dim i As Integer
 Dim str1 As String
 Dim intNum As Long

    str1 = Mid$(strStartingValue, 4, 2)
    str2 = Mid$(strStartingValue, 8, 2)
    
    intNum = str1 & str2
    
    For lngIndex = 1 To 100
        intNum = intNum + 1
        Debug.Print "yjk" & Left$(CStr(intNum), 2) & "kg" & Right$(CStr(intNum), 2) & "dky"

If the letters are always the same you could just do

    Dim str1 As String
    Dim str2 As String
    Dim strNewUnlock As String
    
    
    str1 = Mid$(LastUnlockNumber, 4, 2)
    str2 = Mid$(LastUnlockNumber, 8, 2)
    
    intNum = str1 & str2
    intNum = intNum + 1
    
    strNewUnlock = "yjk" & Left$(CStr(intNum), 2) & "kg" & Right$(CStr(intNum), 2) & "dky"

And I guess that it's unlikely to happen but maybe you should add lines 11 to 14.

 Dim str1 As String
    Dim str2 As String
    Dim strNewUnlock As String
    
    
    str1 = Mid$(LastUnlockNumber, 4, 2)
    str2 = Mid$(LastUnlockNumber, 8, 2)
    
    intNum = str1 & str2
    intNum = intNum + 1
    If intNum > 9900 Then
        MsgBox "Too Large"
        Exit Sub
    End If
    
    strNewUnlock = "yjk" & Left$(CStr(intNum), 2) & "kg" & Right$(CStr(intNum), 2) & "dky"

Thanks martinliss.
this is unneeded
If intNum > 9900 Then
        MsgBox "Too Large"
        Exit Sub
    End If
This is just a list of valid numbers to give the credit card company
I plan on just outputing the list to the debug window and pasting the numbers into their online screen.
in looking at your code should it be put into a loop 1-100 ?

what is this variable LastUnlockNumber ?

Martin I used your code to write this sub:

Sub OutPutRegistractionNumbers() 'temp to output for online code disburstment
Dim i As Integer
Dim LastUnlockNumber As String
 Dim str1 As String
 Dim intNum As Long
    Dim str2 As String
    Dim strNewUnlock As String
     LastUnlockNumber = "yjk50kg01dky"
    
   For i = 1 To 100
    str1 = Mid$(LastUnlockNumber, 4, 2)
    str2 = Mid$(LastUnlockNumber, 8, 2)
    
    intNum = str1 & str2
    intNum = intNum + 1
    
    strNewUnlock = "yjk" & Left$(CStr(intNum), 2) & "kg" & Right$(CStr(intNum), 2) & "dky"
    Debug.Print strNewUnlock
    Next
    
End Sub

Open in new window

but the debug showed :
yjk50kg02dky
yjk50kg02dky sb yjk50kg03dky
yjk50kg02dky sb yjk50kg04dky

increase to 100
last number(100) sb yjk51kg00dk

You can use it as a function. If you run the "test" sub you will get:

Input: yjk50kg01dky output: yjk50kg02dky
Input: yjk50kg55dky output: yjk50kg56dky
Input: yjk50kg99dky output: yjk51kg00dky

Sub test()
OutPutRegistractionNumbers "yjk50kg01dky"
OutPutRegistractionNumbers "yjk50kg55dky"
OutPutRegistractionNumbers "yjk50kg99dky"
End Sub

Open in new window

Public Function OutPutRegistractionNumbers(LastUnlockNumber) As String 'temp to output for online code disburstment

 Dim str1 As String
 Dim intNum As Long
    Dim str2 As String
    Dim strNewUnlock As String
    
    str1 = Mid$(LastUnlockNumber, 4, 2)
    str2 = Mid$(LastUnlockNumber, 8, 2)
    
    intNum = str1 & str2
    intNum = intNum + 1
    
    strNewUnlock = "yjk" & Left$(CStr(intNum), 2) & "kg" & Right$(CStr(intNum), 2) & "dky"
    Debug.Print "Input: " & LastUnlockNumber & " output: " & strNewUnlock
    
End Function

I did this
OutPutRegistractionNumbers ("yjk500kg10dky")
got a type mismatch on this line:
 intNum = str1 & str2
Am i doing something wrong?

isnoend2001Author Commented:
I see i did this too high 500
valid numbers 5000 to 99100
sb yjk50kg001dky the number would be 5001

Martin LissOlder than dirtCommented:
When you said "I want to give them a list of 100 valid numbers are between 5000 and 9900" was that correct or is it 5000 to 99100"?

 low number yjk50kg01dky = 5001
to
high number yjk51kg00dky= 5100

I think i have to upload a hundred unlocking codes. When it gets less than 100 an someone makes a purchase I get a warning: "Low available licenses, please upload more
Each time a user buys the software they are given the first number on the list. I think the number is removed from the list so no 2 users get the same number
