Hello All,
I need to use mshtml.HTMLDocument.createDocumentFromUrl in VB.NET to
load a webpage. The code looks like this
Imports mshtml
Public DocumentFactory As HTMLDocument
would be very grateful if you could let me know how to solve this
problem in VB.NET. I am getting the error "Object reference not set to
an instance of object" I am listing the code below that I am using.
Imports mshtml
Public DocumentFactory As HTMLDocument
Public Function GetWebPage(ByVal strURL As String) As HTMLDocument
Try
GetWebPage = DocumentFactory.createDocumentFromUrl(strURL,
vbNullString)
StatusBar1.Panels(1).Text = strURL
Do Until GetWebPage.readyState = "complete"
Application.DoEvents()
Loop
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Function
On further reading I found that as HTMLDocument is just an interface so
I need to cast it as IPersistStreamInit. Therefater I have got stuck as
I donot know how this needs to be done. Some of the sites I went
through, gave this implementation
Imports System.Runtime.InteropServices
and in the Function GetWebPage(...)... add
Dim ips As IPersistStreamInit
But .NET does not recognize IPersistStreamInit
What to do???
I will be grateful if somebody gives a solution to this problem.
Any help would be greatly appreciated.
