el textBox, tiene establecida la propiedad de Multilinea?
en todo caso, en el Api Guide hay un ejemplo de como poder hacer eso, de leer el "source" de una pagina,, InternetReadFile
Const scUserAgent = "API-Guide test program"
Const INTERNET_OPEN_TYPE_DIRECT = 1
Const INTERNET_OPEN_TYPE_PROXY = 3
Const INTERNET_FLAG_RELOAD = &H80000000
Const sURL = "http://www.microsoft.com/index.htm"
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 Sub Form_Load()
'KPD-Team 1999
'URL: http://www.allapi.net/
'E-Mail: KPDTeam@Allapi.net
Dim hOpen As Long, hFile As Long, sBuffer As String, Ret As Long
'Create a buffer for the file we're going to download
sBuffer = Space(1000)
'Create an internet connection
hOpen = InternetOpen(scUserAgent, INTERNET_OPEN_TYPE_DIRECT, vbNullString, vbNullString, 0)
'Open the url
hFile = InternetOpenUrl(hOpen, sURL, vbNullString, ByVal 0&, INTERNET_FLAG_RELOAD, ByVal 0&)
'Read the first 1000 bytes of the file
InternetReadFile hFile, sBuffer, 1000, Ret
'clean up
InternetCloseHandle hFile
InternetCloseHandle hOpen
'Show our file
MsgBox sBuffer
End Sub
fijate si eso te sirve adaptandolo a tus necesidades ovbiamente.
PD: cuando estes desarrollamdo un software, es recomendable usar debug.print, te puede evitar muchos dolores de cabeza
