Vb Net – Change MSN Name

This is just a slightly more efficient way to change your MSN name than using SendKeys.

It uses the SendMessage API in order to set the text, rather than SendKeys.

The code is pretty fully commented, and so there is nothing much to explain…

Below is the full source file:
