Working of AJAX with VB. When you want to get data directly from server. Very useful in ASP Applications, when you need to create dynamic and interactive pages without refreshing page and without making a roundtrip to server. This was made popular in 2005 by Google Suggest.
Google Suggest is using the XMLHttpRequest of Java Script object to create a very dynamic web interface: When you start typing in Google's search box, a JavaScript sends the letters off to a server and the server returns a list of suggestions.
VBcodersPrivate Sub Command1_Click()
Dim objXml
Set objXml = CreateObject("Msxml2.XMLHTTP")
objXml.open "GET", "http://www.w3schools.com/ajax/time.asp", True
objXml.send (Null)
If Not objXml Is Nothing Then
ReGet:
DoEvents
If objXml.readyState = 4 Then
MsgBox "Time at Web is: " & objXml.responseText
ElseIf objXml.readyState = 1 Then
GoTo ReGet
End If
End If
Set objXml = Nothing
End Sub
