When this form updates back to the database and closes, how can I automatically refresh the DataSet in the original form containing the DataGridView?

View 1 RepliesI am trying to post data to a form on my website. This works perfect.To expand off for personal use and education, I decided to try and add proxy support. I got a list of some proxies, and did it up. The proxies work, and all is good. But, when I try this with this specific example, I receive 1 of 2 errors depending on the proxy used.(405) Method Not Allowed or (500) Internal Server Error.I realize that both of these are being caused from the proxy side of things, but maybe theres an issue with my code?
