RE: VB & ADO don't seem to handle numeric fields -- MIDRANGE-L

Peter,

I have had similar error messages from VB, and I traced them to missing
object libraries, after much head scratching. One such error came up on the
CHR() function and when I removed a reference to a missing object library it
worked fine. It's possible that your problem is not in this actual line of
code but somewhere else.

HTH

Subject: VB & ADO don't seem to handle numeric fields


Hi Everyone,

I've got a VB program that's reading a file from an AS400 using ADO. Of the
following 3 lines

        RateCode = AS400rs.Fields("RTCODE")
        RateDesc = AS400rs.Fields("RTDESC")
        RateAmt = AS400rs.Fields("RTAMT")

the first two work and the third one fails with run-time error 5 "Invalid
procedure call or argument". The left side fields are defined as

    Dim RateAmt As Currency
    Dim RateCode As String
    Dim RateDesc As String

On the AS400, WRKDBF shows the fields defined as:

  Seq. Base PF    Field Name Field Description         Key Tp  Pos  Len Dec
   1.0 RATEP      RTCODE                                 1 A     1    10
   2.0            RTDESC                                   A    11    50
   3.0            RTAMT                                    P    61    11  2

I'm using CA Express V4R4M0 Service Level SF63638 running under WinNT 4.0
build 1381 service pack 6; the AS400 in questions is John Ross's Netshare
TS400 which is at V4R4M0 with 5769XE1 *CODE & *LNG installed at V4R4M0 and
showing as *COMPATIBLE.

I've tried defining RateAmt as Currency (as shown), Double (how MS Access
using ODBC defines RTAMT), and Long with no luck. I've tried changing RTAMT
to zoned-decimal with no luck. I can't believe that IBM's ADO provider
doesn't do numeric fields, so what am I missing?

TIA,
