Hello,
 
How To Disable "Zooming" By Export To Plug-In htm?
 
I want, let us say, to show my score but without zoom
 
possibility? Like that the people can see the score and  
 
full architechtonic of it but can not copy it by hand (to  
 
write it down)

I believe it is possible for someone to download your *.myr file directly from its own URL. The URL can be read from the source code, in the HTML page.
 
The downloaded *.myr file could be viewed in the trial versions of MA/HA, as well as in registered versions. Then, it would be possible to view the music in detail.
 
The only way that could be prevented, would be if a *.myr file could be locked to "only open in plugin." I do not believe this feature exists. If the feature does exist, or if it is added, then it would be worth the effort to prevent zoom.
 
I am not the most knowledgeable person here. Other opinions?

Thank you Robert,
I think you are right. The best way is to disable use of right mouse button like I saw on some web pages.
Does somebody knows the code for this?

Disable right mouse is totally uneficient.
 
To read the source code, just go to View menu > Source in Internet Explorer.
 
You have 2 possibilities on right click.
The first, most used is to display an "alert" saying "Hey! Don't touch my images!" when you right click.
=> Maintain the right button down, press "Enter" or "Space" to validate the OK button, and then release the right button of your mouse : you have the right-click menu !
The other method is to do nothing on right click, you can go the address bar and type something like Code:
javascript:document.oncontextmenu=null;
disabling the "do nothing on right click".
 
You can also bypass the right-click scripts by disabling javascript, downloading a page or a full website with wget, HTTrack or similar software.
 
You must know that every page, image, flash, myriad... file you see with your internet browser is temporarily saved on your disk, and then displayed. You can open them, they are in a special directory called "cache".
 
The only way to protect your datas : don't share them on the web !
If it's a product you want to sell, show a demo, e.g. only one page of the score.

Sylvain's advice is best.
 
An alternative: If you have full control over your server, it is possible to use a Perl CGI server-side script (or something similar), that will only display the file to visitors from specific file servers (hosts).
 
This only works if you know your visitor's file server in advance, and if the server name is not hidden by a proxy, and if the server is specific to a unique location (or a small number of locations). It does not work well for dial-in modem, or for AOL.
 
For example, I am now using a public terminal at a university library. Each public terminal has a unique host ID. I could write a web page that could only be viewed at one specific terminal, or at a range of terminals.
 
I could also write a web page that can be viewed only by my father (who is currently using my own computer, somewhere else), because I know the host ID there.
 
I could write a web page that could only be viewed by persons in the Netherlands who are using a particular web host service.
 
It would still be possible for the specific user to share the downloaded music file. But that could happen in any case.
 
If your service provider is one of those "free" or ad-supported services, then you probably cannot use Perl CGI.

Folks, check out this thread in the Democratic Workshop / New Features Request area. It's relevant to this discussion. I posted this back when 9.2 was in beta. Do you think something along these lines would be useful?

Thank you Sylvain and Robert,
As I am not an expert, I think the best way  to do is what Sylvain told
