Hi i have an chm (html help file) on many pages on my website. the thing is i want the help file to open in a different topic according to the page the user opened the help file. does anyone know how to accomplish that ?

my current link is
<asp:Hyperlink id="hyperlink1" runat="server" navigateurl = "filename.chm">TEXT</asp:hyperlink>

how should the link be modified? or is it something i must do from the help file ?

thanks in advance

See this article:  http://support.microsoft.com/kb/902225

You'll need to host the chm file on a file server which allows you to use a UNC file path vs a URL.

yes that is for the known issue that doesn't open chm files at all . my question is if it is possible to open the chm file each time on a different topic according to the webpage i was viewing when i pressed the chm link

Yes, if the website is hosted on an internal network.  The problem is that you cannot open a .chm file to a specific page using a web URL, it must be a file: type address.

Here's an example of how to do it using an internal file URL.


<html>
	<head>
		<title>CHM Page Link</title>
	</head>
	<body>
		<A HREF = "mk:@MSITStore:C:\inetpub\wwwroot\Restricted%20Keywords.chm::/admin_home.htm" target="_blank">CHM Page Link</A>
	</body>
</html>

Firefox requires an extension be installed to read .CHM files without downloading them.  Get the extension here:  http://sourceforge.net/project/showfiles.php?group_id=175748&package_id=201865&release_id=605434

Here's a sample asp script which will do open the chm to a specific page contingent upon the original URL.


<%
strPage=Request.ServerVariables(URL)
SELECT CASE strPage
	CASE	"default.asp"
		Response.Redirect	"mk:@MSITStore:C:\inetpub\wwwroot\Helpfile.chm::/default.htm"
	CASE	"forum.asp"
		Response.Redirect	"mk:@MSITStore:C:\inetpub\wwwroot\Helpfile.chm::/forum.htm"
	CASE	"calendar.asp"
		Response.Redirect "mk:@MSITStore:C:\inetpub\wwwroot\Helpfile.chm::/calendar.htm"
END SELECT
%>

To use the routine as a Sub-Routine, you would append this code to the page from which you're calling it (or to an included file), then call it with "Call Helpfile" (not including quotation marks).


Sub	HelpFile
	strPage=Request.ServerVariables(URL)
	Select Case strPage
		Case	"default.asp"
			Response.Redirect	"mk:@MSITStore:C:\inetpub\wwwroot\Helpfile.chm::/default.htm"
		Case	"forum.asp"
			Response.Redirect	"mk:@MSITStore:C:\inetpub\wwwroot\Helpfile.chm::/forum.htm"
		Case	"calendar.asp"
			Response.Redirect "mk:@MSITStore:C:\inetpub\wwwroot\Helpfile.chm::/calendar.htm"
		Case Else
			Response.Redirect	"C:\inetpub\wwwroot\Helpfile.chm"
	End Select
End Sub

so this works only in an internal network and not if the site is on the internet correct ?
