Hallo,
Diese Methode lädt die angegebene Seite (sUrl) und speichert den HTML-Text auf die Festplatte mit Namen "provider_page.txt" Nun kannst du die Datei ganz normal untersuchen mit den String-Funktionen wie
GetLength()
Find()
Mid()
etc....
Viel Spaß & Ciao!
int CCallStockValue::ConnectAndReadPage(CString sUrl, CString &sPageText)
{
CInternetSession netSession;
CString sMessage;
CStdioFile* pFile;
CFile OutFile;
int iStatus = -1;
int iBytes; // Count of readed bytes
char sBuffer[1024]; // Buffer
CCallStockValue c; // GetApplicationDir()
// Open the html site
if (sUrl == "")
{
sMessage = sMessage + "URL is missing! \n";
AfxMessageBox(sMessage, MB_ICONINFORMATION);
}
else
{
pFile = netSession.OpenURL(sUrl);
if (pFile == NULL)
{
// Connection is incorrect
sMessage = sMessage + "\nConnection the data-provider\n\n" + sUrl + "\n\n" +
"was failed!\n\n";
AfxMessageBox(sMessage, MB_ICONSTOP);
}
else
{
// Open/create local file on hdd at application directory
// to store page
OutFile.Open(c.GetApplicationDir() + "provider_page.txt",
CFile::modeCreate |
CFile::modeWrite);
// Connection is ok, then read html and write to hdd
while ((iBytes = pFile->Read(sBuffer, sizeof(sBuffer))) > 0)
{
sPageText += sBuffer;
OutFile.Write(sBuffer, iBytes);
}
// Close CStdioFile (pFile)
delete pFile;
// Close file (CFile)
OutFile.Close();
// Close net session
netSession.Close();
// Status is OK
iStatus = 1; //
}
}
return iStatus;
}
