I am using Visual Studio 2005 with an MFC application that has functionality to access a web site for a small file. I am using the <code>WinINet</code> functions, <a href="https://msdn.microsoft.com/en-us/library/windows/desktop/aa385483(v=vs.85).aspx" rel="nofollow">see the WinINet API reference in Microsoft Windows Dev Center</a>, which provides a simple set of functions that accesses a web site using URL which specifies the protocol (HTTP, HTTPS, FTP, etc.) to pull down a small file.

Looking on the <code>libcurl</code> site there was a reference to this Microsoft Technical Note, <a href="https://support.microsoft.com/en-us/kb/238425" rel="nofollow">Article Id 238425 - INFO: WinInet Not Supported for Use in Services</a> which is marked as retired as of Aug-12-2015. The article summary is:

<blockquote>
 The Microsoft Win32 Internet Functions (exported from WinInet.dll) are
 not supported when run from a service or an Internet Information
 Server (IIS) application (also a service). This article discusses
 using the WinInet.dll in a service or in Internet Information Server
 applications.
</blockquote>

The applicable source code I am using in my MFC application has a dialog box that uses an HTTPS type URL to which is appended additional information to build a complete URI and then go to the web site to pull the complete small file is:

<pre><code>int GetFile (HINTERNET hOpen, TCHAR * szURL, BYTE szTemp[4096]) 
{
 DWORD dwSize;
 TCHAR szHead[15];
 HINTERNET hConnect;

 szHead[0] = '\0';
 szTemp[0] = 0;

 // Opens a resource specified by a complete HTTP URL.
 if ( !(hConnect = InternetOpenUrl( hOpen, szURL, szHead, 15, INTERNET_FLAG_DONT_CACHE, 0)))
 {
 DWORD dwlasterror = GetLastError();
 if (dwlasterror == ERROR_INTERNET_NAME_NOT_RESOLVED) {
 AfxMessageBox (_T("Error: ERROR_INTERNET_NAME_NOT_RESOLVED - check LAN connectivity."));
 } else if (dwlasterror == ERROR_INTERNET_TIMEOUT) {
 AfxMessageBox (_T("Error: ERROR_INTERNET_TIMEOUT - check LAN connectivity."));
 } else if (dwlasterror == ERROR_INTERNET_SERVER_UNREACHABLE) {
 AfxMessageBox (_T("Error: ERROR_INTERNET_SERVER_UNREACHABLE - check LAN connectivity."));
 } else if (dwlasterror == ERROR_INTERNET_OPERATION_CANCELLED) {
 AfxMessageBox (_T("Error: ERROR_INTERNET_OPERATION_CANCELLED - check LAN connectivity."));
 } else {
 CString msg;
 msg.Format (_T("Error: GetLastError() returned %d."), dwlasterror);
 AfxMessageBox (msg);
 }
 return -2;
 }

 // Reads data from a handle opened by the InternetOpenUrl, FtpOpenFile, or HttpOpenRequest function.
 if (InternetReadFile (hConnect, szTemp, 4096, &amp;dwSize) )
 {
 if (dwSize) {
 return dwSize;
 }
 return -3;
 }
 return -4;
}

int DownloadURLImage (TCHAR * szURL, BYTE szTemp[4096])
{
 int result = -1;
 HINTERNET hInternet;

 // Initializes an application's use of the WinINet functions.
 hInternet= InternetOpen (_T("DeviceConfig"), INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, NULL);
 if (hInternet) {
 // if open succeeded then get the file and close the handle as we be done.
 result = GetFile (hInternet, szURL, szTemp) ; 
 InternetCloseHandle(hInternet);
 }
 return result ;
}
</code></pre>

I've an MFC application that currently uses CAtlHttpClient to query a web server for some information.

I'd like to change this so that the query goes over securely, with server authentication, using SSL.

Googling reveals that Microsoft has changed the way they support this several times, e.g., WinInet, WinHTTP, but for the life of me I can't figure out how to do the above using MFC under MSVS 2005.

The application is in C++, and if at all possible, I'd like to avoid dragging .Net into the picture.

Any help, hints, suggestions or pointers gratefully appreciated!

Thanks,
