'GetDataSet
' Returns a table of data based on the supplied SQL statement and connection string.

' sqlString (string) - The SQL string to be sent.

' This function generates a table of information in a 2 dimensional array. The first dimension represents the columns
' and the second the rows. If an error occurs while the routine is executing the array and the base index (0,0) is set
' to C_ERROR, (0,1) to the VBScript error index, and (0,2) to the VBScript error description.

Om mijn datasets te krijgen. Het geeft een array terug die je als man kunt hanteren (ehmm ... vrouw-handvat?) zoals je wilt.
Als er een fout is, worden de details geretourneerd in de juiste elementen van de array.
