Scanning Using MFC

Microsoft Foundation Classes (MFC) offers good support for Internet connections,

especially when it comes to HTTP and FTP. As described above, scanning is performed by

requesting a

using HTTP. If the operation is successful, the image is returned via a

redirect response. The steps below describe how a scanning is performed using MFC. If you

need more information about the classes described, see the MFC documentation. The

following code is not checked for errors.

1. Create a CInternetSession object:

CInternetSession aSession("ScanSDK");

The parameter is a string identifying the application. An application needs only

one instance of this class.

2. Using this object you can now retrieve an HTTP connection:

CHttpConnection* anHttpConnection =

3. Using this connection, you can now open a request. By default, redirect responses

are handled automatically:

CHttpFile* anHttpFile =

The first parameter defines that a POST request shall be opened, the second is the

request target.

4. Create a query string containing the parameters you want to send:

CString aQueryString =

5. Add an HTTP header which informs the HTTP server that the request contains

encoded data:

anHttpFile->AddRequestHeaders(

aSession.GetHttpConnection("somescanserver",

anHttpConnection->OpenRequest(0,

"\n\npage=scan&profileName=Color+low&scanNow=";

"Content-type: application/x-www-form-urlencoded");

(INTERNET_PORT) 80,

NULL,

NULL);

"/user/scan/scan.shtml");
