We have GUI appliction that use static DLL with MultimediaDD capability (DLL uses APSServer). DLL comes in embedded SIS
I thought that main application may not need MulimediaDD itself.
But if I remove MultimedaDD from main application (and sign it with certificate without MulimediaDD) -- it not starts (Security Error) or calls to DLL return error (probably AccessDenied)
In Symbian Platform Security FAQ written that process can not load DLL with fewer capabilites, but in my case (capability of DLL) = (capability of main application) + MultimediDD, and it not works anyway...
Please anybody -- any ideas are welcomed
