Connecting without setting up ODBC

[Jewtus]

I am trying to connect to a database but I use an ODBC connection on my machine that I'm trying to eliminate the dependence on (I'm using the IBM DB2 connector which is not free... I had a trial version).

This code works, but only if I have the ODBC connector setup in the windows settings:

$oMyError = ObjEvent("AutoIt.Error","MyErrFunc")
$sqlCon = ObjCreate("ADODB.Connection")
$sqlCon.Mode = 16  ; shared
$sqlCon.CursorLocation = 3 ; client side cursor
$sqlCon.Open ("DSN="&$DSN&";UID="&$USERNAME&";Password="&$PASS&";DBALIAS="&$alias)
If @error Then
    MsgBox(0, "ERROR", "Failed to connect to the database")
    Exit
EndIf

Func MyErrFunc()
  $HexNumber=hex($oMyError.number,8)
  Msgbox(0,"COM Test","We intercepted a COM Error !"       & @CRLF  & @CRLF & _
             "err.description is: "    & @TAB & $oMyError.description    & @CRLF & _
             "err.windescription:"     & @TAB & $oMyError.windescription & @CRLF & _
             "err.number is: "         & @TAB & $HexNumber              & @CRLF & _
             "err.lastdllerror is: "   & @TAB & $oMyError.lastdllerror   & @CRLF & _
             "err.scriptline is: "     & @TAB & $oMyError.scriptline     & @CRLF & _
             "err.source is: "         & @TAB & $oMyError.source         & @CRLF & _
             "err.helpfile is: "       & @TAB & $oMyError.helpfile       & @CRLF & _
             "err.helpcontext is: "    & @TAB & $oMyError.helpcontext _
            )
  SetError(0)  ; to check for after this function returns
Endfunc

But I want to connect without needing to install any software on the machine (so there is no localized configurations needed). Does anyone know of a way to get around this? Maybe with a DLL file that I can call directly and include with the script?
