Introduction
This application used to download the file from internet by giving the path.
#include <afxinet.h>
CInternetSession netSession;
CInternetSession having the member function OpenURL() to open the URL.
CStdioFile *fTargetFile;
fTargetFile=netSession.OpenURL(str,1,INTERNET_FLAG_TRANSFER_BINARY|INTERNET_FLAG_RELOAD);
This application displays the download rate and show how much percent downloaded in progress bar.
int filesize=fTargetFile->SeekToEnd();
int outfs;
outfs=filesize/1024;
CProgressCtrl *prg=(CProgressCtrl*)GetDlgItem(IDC_PRG1);
COleDateTime StartTime=COleDateTime::GetCurrentTime();
prg->SetRange32(0,filesize);
int bytesread=0,pos=0;
char strbuf[512];
CString szDestPath;
GetDlgItemText(IDC_EDIT2,szDestPath);
szDestPath+="\\";
szDestPath+=fTargetFile->GetFileName();
CFile fDestFile(szDestPath,CFile::modeCreate|CFile::modeWrite|CFile::typeBinary);
while(bytesread=fTargetFile->Read(strbuf,512))
{
pos+=bytesread;
prg->SetPos(pos);
float percent=(float)pos/(float)filesize;
int p=percent*100;
fDestFile.Write(strbuf,bytesread);
COleDateTimeSpan dlTimeElapsed=COleDateTime::GetCurrentTime()-StartTime;
secs=dlTimeElapsed.GetTotalSeconds();
int kb=pos/1024;
kbpsecs=kb/secs;
CString Kbps,szPercent;
Kbps.Format("%0.1f KB/Sec",kbpsecs);
SetDlgItemText(IDC_STATIC1,Kbps);
szPercent.Format("%d %%",p);
SetDlgItemText(IDC_STATIC4,szPercent);
Sleep(100);
