Bulk SMS using VB.NET 2008
I have built an SMS application using vb.NET 2008 Express edition...the application can send a single SMS from database (addressbook). Now I need to create a form where I can send to multiple/bulk contacts that are stored from the database. It seems I'm failing somewhere but confused...the contacts should be seperated by a deliminated comma ( ; ) in order to be send.
HINT: If I can manage to add mobile numbers from a database and theN join them with a deliminated commas ( ; ) then it can work
Bellow please find the code I use to send a single SMS....YOUR URGENT ASSISTANCE WILL BE HIGHLY APPRECIATED....
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim MyString As String
Dim TxUserName As String
Dim TxPassword As String
Dim TxMessage As String
Dim TxNumber As String
TxUserName = TBUserNameTextBox.Text 'for login purposes
TxPassword = TBPasswordTextBox.Text ' for login purposes
TxMessage = TBMessage.Text 'message box
TxNumber = CellphoneTextBox.Text 'my address textbox where I retrieve the number to send to
MyString = "http://www.mysiteaddress.net/api/batchmessage.asp?User="
MyString = MyString & TxUserName & "&Password=" & TxPassword & "&Delivery=No"
MyString = MyString & "&Message=" & TxMessage & "&Numbers=" & TxNumber & ";"
