> Did you mean to say that I can store the settings in a file and then bundle it with my application?

Yes, it's like a BLOB (binary large object) that you could even store at a database. There should be functions at QuickTime to store/retrieve (aka serialize/deserialize) atom containers. The new ActiveX control of QT7 even has functions to load/store such info (usually returned as a classic atom container structure) as XML (not sure if the XML functionality has been put in the general QuickTime API or just in that control's support libraries).

Users can have a separate GUI to select the settings and store them to a file that is then saved at a place where the no-GUI app/service can get them. When users want to change the settings they'll run the GUI again (at the same or other remote machine) and store the file at the no-GUI app's machine or at some network location from where the no-GUI can access them. The settings GUI can even have a "do export test" checkbox to actually do an export of a small sample file to test the settings after the export dialog returns, apart from using the export dialog just to get the settings and store them.

If yes, that's lovely and I would like to know how, please.

If No, then I have this problem:

The application is meant to be installed and executed on machines where there is no user interaction at all. So I cannot assume that someone will run this separate application to record the settings. Also evertytime the application is re-started someone will have to select the settings which may not be possible/acceptable to the user.

Thanks again.

cheers,

Thanks also for your workaround suggestion, but I cannot use it as my
application is supposed to be exposed as an API from a dll with no user
interaction/GUI at all. If you

you can invoke the export dialog from a normal application and record the
export settings, then use them by the no-GUI library (making the dialog not
show up, but just using the recorded settings and maybe editing them on the
fly by using QTFindChildByID as shown at
