How to use browser link to call a delphi App?

Here is what I would like to do...

If you are viewing a web page with a browser and you click on a link like this one.

<A HREF="http://www.somewhere.com/myfile.abc">CLICK HERE</A>

I would like for my delphi program to be called and the url passed to it so that it can go get the file 'myfile.abc' and process it.

I want it to work just like Real Audio Player does when you click on a link for a file that ends in .ram ..... so how does one link a file suffix like .abc to the program that needs to process the file??

Does anyone know if some other delphi programmer has done this and made a program with source code available? or maybe some kind of a component?

RealAudio is not one program... it's two programs, and it works as a mean of a stream.

The server streams the data to the <OBJECT> R-A application in the client browser.

Hi simonet :)

I was just using Real Audio as an example of how clicking on a link can cause a program to be launched....  I would like to have my program run if a user clicks on a link for a file that ends with a unique suffix like .abc  the way RA is launched when a file ends in .ram
id assume you just need to register your .abc file type in the registry..
then when its clicked it should launch your app..here a function someone wrote:

procedure RegisterFile;

var Reg: TRegistry;

  Reg := TRegistry.Create;
    Reg.RootKey := HKEY_CLASSES_ROOT;
    Reg.OpenKey('\.abc', True);
    Reg.WriteString('', 'MyProgram');
    Reg.OpenKey('\MyProgram', True);
    Reg.WriteString('', 'a very special file');
    Reg.OpenKey('\MyProgram\DefaultIcon', True);
    Reg.WriteString('', Application.ExeName + ', 1');
    Reg.OpenKey('\MyProgram\Shell\open\command', True);
    Reg.WriteString('', Application.ExeName + ' "%1"');
    ShowMessage('successfully registered');

Hi Inthe :)

That looks good!
I will try and get that to work.....
I think I will play with this on another computer..
I'm nervous about experimenting with the registry....I
messed with it once and had to reload windows :-)
