Tom,

I'm using an evaluation copy of QODBC version 6.00.00.155 with Quickbooks Pro 2006.  I am developing applications with Delphi Enterprise 7.0.

I have tried the solution provided, (Max field name length = 32), but am still having the problem.  I have tried different values and that causes different fields to report the error.

My client plans to purchase the licenced version, provided I can get this working.

Thanks in advance!

Sorry, you haven't stated any details on the errors you are getting or what tables and columns are still affected?

Have you established a connection using VB Demo yet? See: How do I connect to QuickBooks for the first time? 

Yes, the VB demo works fine.  The problem is encountered from within various wizzards within the IDE, as well as application output, such as assigning DBEdit boxes to variables.  Rather than to delve into complex explanations and scripts that would require the devepoper IDE, let me produce one simple example:

I have the following code, that dumps the data to a Memo as a debugging tool.  Here is the code:

procedure TForm1.ShowMemo;
var  i: integer;
begin
  InvMemoForm.Memo1.Clear;
  for i:= 0 to QbDm.QBDataMod.InvQuery.FieldCount -1 do
    if QbDm.QBDataMod.InvQuery.Fields.Fields[i].AsString <> '' then
      InvMemoForm.Memo1.Lines.Add(QbDm.QBDataMod.InvQuery.Fields.Fields[i].FieldName + ' = ' + QbDm.QBDataMod.InvQuery.Fields.Fields[i].AsString);
  InvMemoForm.ShowModal;
end;

Here is partial output, copied from the Memo:

InvoiceLineSeqNo = 1
InvoiceLineTxnLineID = 1639C-1110204422
InvoiceLineItemRefListID = 20000-1001006699
InvoiceLineItemRefFullName = DESTRUCTIVE TESTING
InvoiceLineDesc = DESTRUCTIVE TEST
InvoiceLineRate = 110
InvoiceLineAmount = 110
InvoiceLineSalesTaxCodeRefListI = 20000-1135001387
InvLnSalesTaxCodeRefFlNm = Non
FQSaveToCache = False
FQPrimaryKey = 1639A-1110204422|1639C-1110204422|

Note on line 8 "InvoiceLineSalesTaxCodeRefListI" should be "InvoiceLineSalesTaxCodeRefListID"
