Hello,

I would like to open a 'Help.chm' file on a button click.
I got the advice to use a Process object.

//create a process
Process prc = new Process;
//add filename to the process
prc.StartInfo.FileName="Help.chm";
//open file
prc.Start();

this all works fine.

If I click the button twice I get an exception error that the file is
allready open.
Can I somehow set the openened file to modal?
Or can my application somehow been signalled when the file is closed
by the user?

I tried a Process control on my form but it's 'Exited' event is not
executed on file closing.

All tips welcome,

regards,

Henk

You could use the HtmlHelp API to open the window with your CHM file. It
will reuse the existing window if you invoke it the second time.
