Hi all,

This is my first post in here.

I am trying to create a code to get HTML data from the web (without using a web browser element), creating a local variable to store the data and being able to parse it later on using the GetElementById method.

The problem is that I am getting an error and I?m not sure how to fix it.

the code is as follows:

VB.NET:
Imports mshtml

Sub Getelement()  

        Dim url As String
        Dim XMLHTTP As Object, html As IHTMLDocument2 = New HTMLDocument
        Dim obj_tbl As HTMLElementCollection

        url = "url to be used "

        XMLHTTP = CreateObject("MSXML2.XMLHTTP")
        XMLHTTP.Open("GET", url, False)
        XMLHTTP.setRequestHeader("cache-control", "no-cache, must revalidate")
        XMLHTTP.send()

        html.write(XMLHTTP.responseText

        obj_tbl = html.getelementbyid("id")

    End Sub

The error returned is : "Unable to cast COM object of type 'System.__ComObject' to interface type 'mshtml.HTMLElementCollection'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{3050F56B-98B5-11CF-BB82-00AA00BDCE0B}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."


I have looked for a solution everywhere, but no way to find something without using a web browser in the code.

This is my very first code in VB 2010 so it might contain several errors.

Could anyone help me?

thanks in advance.
