Open With

[croftstorm]

Hi

How do I let an application carry out a function on a file when it is opened with the application?

Bit hard to explain, so an example: I want MyApplication to read MyFile. So I right click MyFile and select 'open with' then choose MyApplication. MyApplication should then open and carry out a function on MyFile to read it.

I expect that this is in the manual, but I can't seem to find it. Help appreciated.

1. Use the Application.associate method to associate your file with your application. Then when you double click the file in the Windows Explorer, your application will be launched to open the file. In this case, the Windows explorer just passes the name of the file as a command line parameter to your application

2. Handle the command line parameter

var cmdItems = Application.cmdItems;
if (cmdItems.length > 0)
{
    var filename = cmdItems[0];
    Dialogs.msgBox(filename + " is opened!");
}

Hi thanks for the help, that's what I was looking for.

But for some reason it still wont work:

Application.associate('.ccg', "Demo.type");
var cmdItems = Application.cmdItems;
if (cmdItems.length > 0)
{
    //cmdItems[0] is the name of the file
    Dialogs.msgBox(cmdItems[0]);
}

When I run the application the .ccg files stay associated with Notepad. Could the Demo.type part be incorrect? I was not sure what to put there.

Thanks,
Mark

We have tested it and find that it works.

Application.associate(".ccg", "CCg.type");
var cmdItems = Application.cmdItems;
if (cmdItems.length > 0 && cmdItems[0] != "con")
{
    //cmdItems[0] is the name of the file
    Dialogs.msgBox(cmdItems[0]);
}

The second argument of the associate method is a unique type identifier of your file. If you want to add menu items into the right click menu in Windows explorer, you would have to add more registry entries. You may find some articles in Microsoft MSDN by searching with the keyword "Shell Extension".
