Download file using CInternetSession [modified]

[john5632]

Hi, I am trying to download a zip file from server using CInternetSession. But i am getting incorrect size from server. My application is unicode and code as below:

pConnection = session.GetHttpConnection((LPCTSTR)strServerName, (INTERNET_PORT)nPort);//, (LPCTSTR)NULL, (LPCTSTR)NULL);
LPCTSTR pstrAcceptTypes = NULL;
LPCTSTR pstrVersion = NULL;

// Open and send the request
pHttpFile = pConnection->OpenRequest(CHttpConnection::HTTP_VERB_GET, strObject, NULL, 1, &pstrAcceptTypes, pstrVersion, HttpRequestFlags);

          pHttpFile->AddRequestHeaders(szHeaders);
    pHttpFile->AddRequestHeaders(\_T("User-Agent: GetWebFile/1.0\\r\\n"), HTTP\_ADDREQ\_FLAG\_ADD\_IF\_NEW);
    pHttpFile->SendRequest();

    pHttpFile->QueryInfoStatusCode(dwRet);//getting 200

    int nFileLen = pFile->GetLength(); //getting 7

why I am getting incorrect size? Anything wrong in this code? Same code was working with ANSI build and not working with unicode build.

I think you can try the function URLDownloadToFile(). http://msdn.microsoft.com/en-us/library/ms775123(v=vs.85).aspx[^]

where is pFile defined and initialised? It does not appear in this code snippet.

I must get a clever new signature for 2011.

sorry this is

pHttpFile->GetLength(); //getting 7

Is the incorrect size comes in debug version? Please run in release mode and analyze nFileLen by means of messagebox or some thing else.

Sorry, no idea, but maybe you should be looking at the information returned from your server. [edit]Google found this[^], it may help.[/edit]

Previously code was in ANSI and working fine but now I converted it to UNICODE and getting this issue. Any problem with API to transdfr the string to server into UNOCODE format?

Assuming both ends are working in Unicode there should be no problems. You need to check both ends are following the same rules.
