Sharepoint connection and interaction

[lalberti]

I need to develop an office add-in to perform interaction with a Sharepoint
Server.
What I need is programmatically connect to the sharepoint site and upload
documents and data.
Where can I find informations, resources and code samples about it?

At the moment I tried to do it with the code listed below but I receive a
COM Exception (system.runtime.interopservices(COMException)).



imports Microsoft.SharePoint

Public Class Form1

Inherits System.Windows.Forms.Form



Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click

Dim url As String = "

http://labsps0/content/"

Try

Dim s As New SPSite(url)

MsgBox(s.Url)



Catch ex As Exception

MsgBox(ex.Message)

End Try

End Sub

End Class
