Problem accessing the resource in SP website

Question

I am new to SP and my boss created a sharepoint resources, at let's say abc.sharepoint.com My boss wish to access the resources using a .NET program. My developing computer does not have Windows Server but attempted to use the API by importing referenced founded
in .NET. I used the code which can be found in Google and implemented as follow:
Imports Microsoft.SharePoint.Client
Imports System.Security
Imports System.Net
Public Class Form1
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim cc As New ClientContext("http://abc.sharepoint.com")
Dim SecureString As New SecureString()
Dim Password = "MyPassword"
For Each c In Password
SecureString.AppendChar(c)
Next
cc.Credentials = New SharePointOnlineCredentials("MyUsername", SecureString)
cc.Load(cc.Web, Function(w) w.title)
Try
cc.ExecuteQuery()
msgbox("Hello World")
Catch ex As Exception
msgbox(ex.Message)
Exit Sub
End Try
End Sub
End Class
I think I could reached the resource but it returns 401 Unauthorized Error. When I use a wrong password, it returns that my login information is incorrect.
What is the reason for appearing 401 and how to solve it. Thanks a lot.
