One alternative might be to add the DataTable to a DataSet and then convert the DataSet to an XML string using WriteXml().

That said, quick question: Any reason why you're using .NET in this case instead of using the exising COM Sap Connector? Wouldn't that be easier?

Thanks for you help Tomasr.

I already solve the problem, I dont like the process but its working, right now Im copying all the rows of the datatable to a recordset and then returnig the recordset to VB6. And Im going to test converting the DataTable to xml to see if works better.

I dont use de COM connector because I think its obsolete, and I didnt find complete documentation.

.NET to COM question ( Dictionary in COM and .NET dictionary)
 I need to write a data access code to replace the method of GetPerson() in COM data access, since the existing method is too slow. .NET can reduce the database round trips by using the dataset. The existing COM data access will stay except the GetPerson() method. So I am going to call the .NET getPerson() mehtod from the COM,  The original GetPerson() method in COM just go to data base, pull data from 7 tables and write to dictionary.  If the .NET getPerson() can populate the COM Dictionary, that would be great! I know .NET object can be directly assign t...

Call to non .net COM not working after .NET

.NET classes hindering .net assembly from being com?
I posted an earlier thread about instanciating a .net assembly from a com client, like an asp page. My problem was that no matter what I did, I could not get the class to instaciate, so I could not call any methods on that class. After quite a bit of trial and error, as far as weak and strong named assemblies, GAC, etc, I came to the conclusion that the object WAS being referenced properly, therefore it was not a problem getting access to the object's class declaration. My problem was that everytime I called a method on the object, I got a "object not set to instance" error. ...

To .NET or not .NET, that is the question
I'm running WinXP pro 32-bit, meaning I've got the version 1-dot-something of .NET that XP came with. I've been looking for various softwares, and more and more often come across .NET version 2 being prerequisite. No urgency for me re. my questions to this group - so far I have just decided to hit the red X on those download pages - but the desire for this newer version of .NET seems to be growing for me. Firstly, according to my (limited) research, newer .NET versions are inclusive of the previous ones, and the current version seems to be 3.5. So if I go for i...

from COM to .NET
Hi all, My company are slowly migrating from vb6/com environment to a .net/web service environment. At the moment we have a financial system running on our intranet that allows user to request and retrieve reports- we have a .Net web service that retrieves these requests and passes them on to a COM dll, which queries the database and generates the reports using Crystal. After some testing, we've found that when there's more than one person running reports, the system crashes. After some research i've found out that calling a COM component with a .net web service can have threading iss...
