Tutorial: How to convert
RSS to HTML using You can download the source code of this example here: rss2htmlscout_vc.zip This page will teach you how to use Visual C++ and RSS2HTML Scout ActiveX library to convert RSS into HTML in your VC application. RSS2HTML Scout is
capable of downloading RSS feeds using built-in multi-threaded and converting
RSS into HTML code using HTML templates (check online
documentation for more information about templates)
Download and install the latest version of RSS2HTML Scout. You can download it here 1) Run Visual C++ 2) Select
the "New.." command
from "File" menu
(as it is shown below) to run :
 3) New
Project Wizard dialog
will appear on the screen. Select "Win32
Console Application" project
type and enter "HelloWorld" as the Project name as shown on the screenshot
below:
  4)
The wizard will ask what kind of Console Application you want
to create. Select A
"Hello, World!" application and
click Finish:
 VC++ will
show summary information for the new project. Click OK:
 Visual C++
will generate application code for a simple console application
The source code editor
window will appear. To edit main() function just open the
class tree on the left and double click on "H elloWorld Classes"
| "Globals" | "main (int argc, char* argv[1])":
 VC++ will open main() function:
 5) To
use RSS2HTML Scout ActiveX in VC++
application you have to tell the compiler to import type library information
into the project.
To import type library just add #import compiler
directive after #include directive:
#import "RSS2HTMLScout.tlb"
using namespace RSS2HTMLScoutLib; 6) The
code snippet below will convert RSS to HTML using RSS2HTML Scout ActiveX
library
#include "stdafx.h"
#import "RSS2HTMLScout.tlb"
using namespace RSS2HTMLScoutLib;
int main(int argc, char* argv[])
{
// initialize OLE
HRESULT hr = CoInitialize(NULL);
// check for errors
if (FAILED(hr)) {
MessageBox(0,"OLE initialization errp","error",MB_OK);
return -1;
}
// declare SWFScout object
IRSS2HTMLScout* RSS2HTML = NULL;
CLSID clsid;
// get inuque ID for IFlashMovie interface
hr = CLSIDFromProgID(OLESTR("RSS2HTMLScoutLib.RSS2HTMLScout"), &clsid);
// check for errors
if (FAILED(hr)) {
MessageBox(0,"Can't get CLSID for interface","error",MB_OK);
goto Uninit;
};
// create FlashMovie object
hr = CoCreateInstance(clsid, NULL, CLSCTX_ALL,__uuidof(IRSS2HTMLScout), (LPVOID*)&RSS2HTML);
// check for errors
if (FAILED(hr)) {
MessageBox(0,"Can't create RSS2HTMLScout object","error",MB_OK);
goto Uninit;
}
RSS2HTML->ItemsPerFeed = 5; // display only 5 latest items
// ##### we can add more than one RSS feed #########
RSS2HTML->AddFeed("http://bytescout.com/news.xml", 180); // update every 180 minutes (3 hours)
RSS2HTML->Execute();
RSS2HTML->SaveOutputToFile ("RSS2HTMLOutput.html");// save output to HTML file
// disconnect from library
RSS2HTML->Release();
// uninitialize OLE libraries
Uninit:
CoUninitialize();
return 0;
}
Hint:
you can simply copy and paste the code from the sample above into VC++ code editor window. 7) Run
the application by pressing F5 (or
use "Build" | "Debug" | "Go")
VC++ will compile and run "Hello,
World!" application. It will generate HTML code and then will save it into RSS2HTMLOutput.html file.
You can view generated
HTML file using Internet Explorer or another browser.
To display HTML files in your Visual C++ application please use WebBrowser
control
