how to detect a click on certain part of graphic for help

[Nifrabar]

Hi!
I am creating a helpfile for my vfp-app.
I remember from years ago I saw a program which had possibility to devide a grapic in many areas. A click on that graphic resulted in receiving the ID which belonged to that area of the graphic.
I don't remember which program that was an...
would it be possible to use that in the nowadays CHM helpfiles.

You can make any area of a graphic in a VFP app clickable by overlaying a transparent shape, of course.

But it almost sounds like you're talking about an HTML Imagemap. Those SHOULD (note I did not way will) work in an HTML help file.

There are tons of tools on the web for creating an imagemap. Google should turn them up.

Bart,

You asked in another thread for recommendations for a CHM authoring tool. Have you chosen one yet?

The reason I ask is that the feature you are looking for is a function of the authoring tool. As Dan says, HTML has a control called an Imagemap which does what you want, but it is up to the authoring tool whether it supports that.

Hi Dan and Mike,
Thanks for response.
I will take this with my thoughts which app to select for creating help-files.
From investigations on the web it's not always clear if the app gives the functionality I look for. So experiences of others is quite worthfull.

Bart,

I've never actually used an Imagemap in a CHM file (or on a web page, come to that). But that's probably because I'm basically not a graphics person.

Mike,
My idea is to have a screendump in the helpfile and give that hotspots which has to be connected to hyperlinks elsewhere in the helpfile.

You can create individual hotspots by using the .MouseDown() event

[COLOR=blue]IF BETWEEN(nXCoord,24,50) AND BETWEEN(nYCoord,24,50)
[tab]* Code
ENDI

IF BETWEEN(nXCoord,51,75) AND BETWEEN(nYCoord,24,50)
[tab]* Code
ENDI
[/color]

Chris,

But Bart wants to do this in a Help file.

You may well be right in which case then it's not a VFP question at all but should be posed in forum764

A click on that graphic resulted in receiving the ID which belonged to that area of the graphic.

I read that to be that the hotspot on the VFP form would create the HelpContextID in turn linking to the relevant page in the .chm.

Chris,
Mike was right. Initially I looked for this to create the helpfile.
But meanwhile I also see need to have same functionality on a form.
In fact I am working on a administration program to manage a cemetry. Thee is a kind of planview showing all locations.
Whith your solution I may be able to point to a location and couple my table with data to it.
So, a 'double 'solution for both help and vfp-form!.
Anyway thanks to both of you!
For now I think we may close this topic.
