I've posted this code once before, but it was in digest authentication. Here are the changes I made to make it work for basic authentication. Many thanks to CC for being sooo supportive of us .Net developers...NOT. Actually thanks to peers in the forum for your direction. Code changes marked in bold.

Thanks for posting the sample code. This code is for our Bulk Activities collection. This is intended only for adding 25+ contacts at a time using bulk jobs. If you are looking for code for modifying or creating a single contact, please see this post for sample C# .NET code. This code is easily modifyable to VB .NET and has been tested there as well.
Please note, it is against the Terms & Conditions of the Constant Contact API to use the Bulk Activity Collection for single contact adds such as Sign Up Forms. If such abuse is detected, deactivation of the API Key may occur until the code is updated to not abuse the Constant Contact API.
