dear builders,
can someone explain me how to download a file WITHOUT
using the FTP protocol...in our firm we ONLY can access
the 80port HTTP..
so, my question: how can i download a file via:
InternetOpen( ), InternetConnect, InternetOpenFile( ), etc...
the below snip will download a file ONLY via the FTP...
/*****************************************************/
#include <WININET.h>
#include <stdio.h>
void ResponseInfo(char *where)
{
char lpBuffer[8*1024];
DWORD Err = GetLastError();
DWORD Llp = 8*1024;
if(Err < INTERNET_ERROR_BASE)
{
sprintf(lpBuffer, "Standard Windows Error Number %i", Err);
}
else
if(Err == ERROR_INTERNET_EXTENDED_ERROR)
{
InternetGetLastResponseInfo( &Err, lpBuffer, &Llp);
}
else
{
sprintf(lpBuffer,"Standard.Internet.Error.Number.%i",Err);
};
MessageBox("..", lpBuffer, where, MB_OK|MB_ICONINFORMATION|MB_TOPMOST);
}
void __fastcall TfrmMainUnit::Button1Click(TObject *Sender)
{
HINTERNET handle_Session = InternetOpen("My App", 0, 0, NULL,
INTERNET_FLAG_ASYNC);
if(!handle_Session) {ShowMessage("Open Session = failed !"); return;}
HINTERNET handle_Connect = InternetConnect(handle_Session, "ftp.halvani.de",
INTERNET_DEFAULT_FTP_PORT,
"USER", "PASS",
INTERNET_SERVICE_FTP, 0, 0);
if(!handle_Connect)
{
InternetCloseHandle(handle_Session); ShowMessage("Connection = failed !");
return;
}
else
{
if(FtpGetFile(handle_Connect, txtRemoteFile->Text.c_str(),
txtLocalFile->Text.c_str(),
FALSE, FILE_ATTRIBUTE_NORMAL, FTP_TRANSFER_TYPE_ASCII, 0))
{
ShowMessage("Download of File = successfully !");
if(InternetCloseHandle(handle_Session)) ShowMessage("Closing Session =
successfully !");
else ShowMessage("Closing Session = failed !");
}
else
{
ShowMessage("Sorry, couldn't connect..");
if(InternetCloseHandle(handle_Session)) ShowMessage("Closing Session =
successfully !");
else ShowMessage("Closing Session = failed !");
}
}
