I have the following two programing problem:

1) how do I add a entry in the context popup-menu which will be shown by every file or directory and not only by the associated.

2) a program gets his parameters from the commandline. the program can be started by an entry in the context popup-menu of the explorer. the problem is that windows starts for every file an extra instance. yes, i'm using 'app.previnstance' to prevent this, but what i need are the commandline parameters of all instances. have you any idea how to make it work?
