I'm trying to write a vb.net program that will upload a file to a FTP site that has SSL (explicit, although I'm not sure what this means).The sample code and explanations I've Googled always assume when it's SSL that I'm using a client certificate. But I have no certificate to load.I simply need to login, accept their certificate and upload my file.When I accept their certificate am I actually installing it on the client? For example of FileZilla a box pops up and I just click on accept, then my login is complete.

I am using the main FTP account for my website which has access to all of my files. I set up a different FTP login to use that only has access to a specific folder, but when I try to use it I get: Error 550 No such file or directory or access denied.
This FTP account allows access to: mywebsite.com/upload/users/ only If strFTPAddress = mywebsite.com/upload/users/ I get error 550, I've tried a few other things too and it's told me that it's an invalid URI
Basically what I want to know is if and how I might be able to connect using my second FTP account so that I only have access to the upload/users/ directory.

The server committed a protocol violation. Section=ResponseStatusLine" . The response I should receive is in XML format where I have as elements the error result (ok or error), the error number and the error description. Here is the code I have:

But, on the contact us page it fails and this is what it says: The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.Requested URL: /default.aspx, 2; url=default.aspx The weird thing is this doesn't happen in debug, only on the live site. It looks like it's appending the header twice somehow...

Using VB 2008 .NET 3.5..I am working on an N-Layer desktop application.Suppose a method in the BLL runs into an situation where the user needs to be notified and the method needs to wait for the user input (OK, Cancel, etc.) before continuing.Assume that this situation happens fairly often but not all the time, and is expected. It doesn't seem correct to throw an exception. The only solution I have so far is to raise an event with a custom EventArgs, and allow the UI to set some property in the custom EventArgs to reflect the user input.
