parsing Html page
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. ------------------------------------------- Option Explicit Const INTERNET_OPEN_TYPE_DIRECT = 1 Const INTERNET_OPEN_TYPE_PROXY = 3 Const INTERNET_FLAG_RELOAD = &H80000000 Private Declare Function InternetOpen Lib "wininet" Alias "InternetOpenA" (ByVal sAgent As String, ByVal lAccessType As Long, ByVal sProxyName As String, ByVal sProxyBypass As String, ByVal lFlags As Long) As Long Private Declare Function InternetCloseHandle Lib "wininet" (ByVal hInet As Long) As Integer Private Declare Function InternetReadFile Lib "wininet" (ByVal hFile As Long, ByVal sBuffer As String, ByVal lNumBytesToRead As Long, lNumberOfBytesRead As Long) As Integer Private Declare Function InternetOpenUrl Lib "wininet" Alias "InternetOpenUrlA" (ByVal hInternetSession As Long, ByVal lpszUrl As String, ByVal lpszHeaders As String, ByVal dwHeadersLength As Long, ByVal dwFlags As Long, ByVal dwContext As Long) As Long Private Declare Function InternetAttemptConnect Lib "wininet" (ByVal dwReserved As Long) As Long Function DownloadPage(sURL As String, Optional Length As Long) As String 'this sub written by 'KPD-Team 1999 'URL: http://www.allapi.net/ 'E-Mail: Dim hOpen As Long, hFile As Long, sBuffer As String, Ret As Long 'Create a buffer for the file we're going to download If Length = 0 Then Length = 10000000 sBuffer = Space(Length) 'Create an internet connection hOpen = InternetOpen("", INTERNET_OPEN_TYPE_DIRECT, vbNullString, vbNullString, 0) 'Open the url hFile = InternetOpenUrl(hOpen, sURL, "", 0, INTERNET_FLAG_RELOAD, ByVal 0&) 'Read the first 10000 bytes of the file InternetReadFile hFile, sBuffer, Length, Ret 'clean up InternetCloseHandle hFile InternetCloseHandle hOpen 'Show our file DownloadPage = Left$(sBuffer, Ret) End Function |
