C# version of turning a website into a chm file. Requires that html workshop (http://msdn.microsoft.com/library/en-us/htmlhelp/html/vsconhh1start.asp) is installed. If anyone knows of a working open source chm compiler let me know.

Can be used like:
html2chm.Html2chm action = new html2chm.Html2chm();
This will run and prompt you for which website directory and which file in the directory to convert to a chm file.

Or it can be used like this:
bool eachFileAsTopic = true;
html2chm.Html2chm action = new html2chm.Html2chm(@"\\Path\to\directory\to\convert", @"mainTopic.html", eachFileAsTopic);

using System.Windows.Forms;
using System.Diagnostics;

    public class Html2chm
    {
        //http://www.majorsilence.com/csharp_html2chm
        //The generated CHM file is named YourCHMFile.chm on your desktop.

        string HHC;
        // Path to hhc.exe

        // Directory path where HHP file is stored
        // and base directory of the html files to be converted
        string RepBase;

        string FicHHP;
