upload a pdf to SharePoint 2010 document collection site through VB Windows Form

Some existing report viewers and schedulers can do that :

However, I don't think somebody will share code from a commercial tool.

I found this document:
http://www.c-sharpcorner.com/uploadfile/dhananjaycoder/programmatically-adding-document-to-sharepoint-document-library/

Converted to VB, now just researching how to add reference for SharePoint.Dll, not showing up.

I guess because it's .net 3.5. I hate to revert my project backwards

I take it that you just can't take sharepoint dll from the server, because SPS does not support remote calls unless the app resides on the SPS Server. I must use the web services.
OK - Got that, so how do I incorporate web services from SPS with Windows App?

Do I use a an event reciever, and will I be able to call that remotely?

Thanks. I guess I do not want to use web services. I have a program already built in VB, and need to put an add on that will upload to SPS. I don't want to create a web app, but upload it directly from a windows form.

You do not need a web app to use web services. You can use that from winforms.

I have this code, but getting a 500 internal error. If I change the username to domain\username I get a 401 unauthorized. I feel I am close...

when I change the path to  "http://SharePointserver/test5/Shared%20Documents/allitmes.aspx" it writes the file to the site, however           "http://SharePointserver/test5/Shared%20Documents/allitems.aspx" becomes corrupt and PDF tries to open when navigating to that site. I uploaded a PDF file and the web browser is tring to open that file when you navigate to it.

Ok - I got it-

 only change in the above code is this and it works.

UploadFileToSharePoint( _
                uploadedFilePath, sharePointListPath + "/" + "1.pdf")

Now, if a user selects a file from the above code, How can I just pull the filename from the full path so I can make it a string the above "1.PDF" ?
Thanks

Ok Success- create a function and add:
 Dim sList() As String
        Dim sAns As String
        Dim iArrayLen As Integer
        Dim fullpath As String = textbox1.Text
        Dim namefromfullpath As String

        If Len(fullpath) = 0 Then Exit Sub
        sList = Split(fullpath, "\")
        iArrayLen = UBound(sList)
        sAns = IIf(iArrayLen = 0, "", sList(iArrayLen))

        namefromfullpath = sAns


Thanks CodeCrusier for directing me in the right path....
