First two letters, space, year in four digits, two digit month, dash, invoice number :

Module Module1
Sub Main()
Dim strInvoice As String = ""
Dim intInvoiceNumber As Integer = 0
intInvoiceNumber = 12345
strInvoice = "KS "
strInvoice &= Format(Date.Now, "yyyyMM")
strInvoice &= "-" & intInvoiceNumber.ToString
Console.WriteLine(strInvoice)
Console.ReadLine()
End Sub
End Module

Adding all your data into a combobox will allow you to do this. On the combox box set the following properties

Combobox1.Sorted = True

Combobox1.AutoCompleteMode = Append

Combobox1.AutoCompleteSource = List Items

This will allow you to type in the combobox and will auto pick the items.
