I registered a file-type XYZ with my MDI-application,
so that a file can be loaded from Windows Explorer with a double-click.
If my app is already running and a second file is opened
via double-click, a second app is being opened.
But I want a second MDI-child to be opened in the first app.
Can someone give me a source sample for this ??
I don't know if this is a hard question, but I need a
quick (and working) answer, so it's worth the points for me.
