Downloading file via HTTP connection using CHttpFile fails

[dc_2000]

Hi everyone:

Here's a code snippet I was intending to use to download files via HTTP connection:

LPCTSTR pURL = _T("http://www.google.com");


//Open session
CInternetSession InetSess(_T("my prog"));

//Get pointer to CHttpFile
CHttpFile* pHttpFile = (CHttpFile*)InetSess.OpenURL(pURL, 1, INTERNET_FLAG_TRANSFER_BINARY | INTERNET_FLAG_RELOAD);
if(pHttpFile)
{
	//Get size of file
	ULONGLONG ncbSz64 = pHttpFile->GetLength();
	ULONG ncbSz = (ULONG)ncbSz64;

	if(ncbSz == ncbSz64)
	{
		//Reserve data
		pBuff = new BYTE[ncbSz];

		if(pHttpFile->Read((BYTE*)pBuff, ncbSz) != ncbSz)
		{
			//Success!
		}
	}
}

Somehow when it runs, pHttpFile->Read returns success and correct file length read but the memory at pBuff is filled out only to the first 200-300 characters. I never programmed HTTP before, what am I not doing right?

Why you are not using: ::URLDownloadToFile () ?

Hmm. I don't know. I didn't come across that API. I'll give it a try. Still what about the sample above?

You need to get the connection after session to obtain the HttpFile,
