INTERFACE AS/400- .NET

[Gina L. Hernandez]

Hello:

I wrote this code to have an interface between AS/400 and Visual .Net.
This code works for a limited number of items, but after that it blows up
and says this message

ERROR String input in the wrong format just in the line of
da.Fill(mytable), it means that just in the moment when I am trying to
retrieve the data with the data Adpater , something happen.

Does Somebody know what it's happening or have a nother way to have the
interface between AS/400 and .NETT??.

SOme of thew fields in the list for the accesss to AS/400 are PACKFIELDS,
that's why I haven't been ABLE to use OLEDDB with that.

I will aprecciate all the help.

Thanks

Hi,

Personnaly I created a AS400 net Data XML Interface that work as a web
service. You submit an SQL String and the system return the XML File in a
public folder of the AS400 Web server.

Then I use dot Net XML Objet to read data and transfer it into my
controls...

The problem is you have to create an XML parser. I think you have to verify
if the buit in AS400 Apache Server is not able to generate those files.

The interest of this technique is that you use only one AS400 Client access
licence...
