Re: Hello World?

try this Jack. The code reads all the rows of the first srcmbr of a
source file. Then writes the rows to a ListBox.

create a C#, Windows, WPF application.

in ODBC dta source administrator make sure you have a User DSN that is
configed for your as400.

Change the code to use your DSN, user name and password. Then change
the "select from " statement text to select from the file you want.
Should work for there.
