Hi,
The easiest way to send e-mail with LabWindows/CVI is to use internet toolkit. This toolkit supports SMTP e-mail protocol.
The internet toolkit is included in the Measurement Studio Enterprise toolset which you can find here. I believe you can also still order it separately, but it isn't listed separately in the catalog anymore. Call our sales representatives to order it separately at 1-800-433-3488.
