how to open chm file using hyperlink

Question

I am developing a web application in which I implemented the help.chm file.

My question is:

How to open the chm help file by using a hyperlink in my web application without a download dialog box?

Answer 1

You can't and you shouldn't. A chm is a file archive that requires a separate viewer, it isn't rendered directly inside the browser.

There are also security considerations with these files, so with certain versions of Windows you cannot open them from a remote (including network) location - they must be opened from the local machine (IIRC this is on WinXP SP2+, Vista and Win 7).
