parsing Html page

[mino]

Hi.
I need to get data from a web page from Excel (no query web).

I need to put in a variable (es. mycode) all the html code, afterwards I
will parse the string "mycode".

I call in my sub a function DownloadPage (API) found in KPD-Team 1999 (see
code below).
It works but sometime the page processed is not completly loaded, so I lost
some data.

I am not expert, so I ask if there is the possibility to put in a string the
html code with another method.

Thanks
M.

Give this a try.

Sub ViewSource()
Dim strURL As String
Dim strPageHTML As String

strURL = "http://www.google.com/"

On Error Resume Next
Set objHTTP = CreateObject("MSXML2.XMLHTTP")
objHTTP.Open "GET", strURL, False
objHTTP.Send
strPageHTML = objHTTP.ResponseText
MsgBox strPageHTML
Set objHTTP = Nothing
End Sub

Sorry Tom I am not expert.

I mean if it is possible to use in Vba-Excel object like WebClient (see
below visual studio code) and if yes, how do it.
Thanks
