Series 60 2nd/3rd hide application icons

Application of series60 2nd and 3rd platformsProgramYou can hide the application icon by setting the den attribute of the Application Registration structure. However, the two platforms use different structures. The file name of this structure is usually xxxx_reg.rss:

Series 60 2nd:

Resource aif_data
{
App_uid = 0x0000000; // app uid
Num_icons = 2;
Embeddability = kappembeddable;
Hidden = kappishidden;
}

Series 60 3rd:

Resource app_registration_info
{
App_file = "yourproject ";
Localisable_resource_file = "// resource // apps // yourproject ";
Localisable_resource_id = r_yourproject_localisable_app_info;
Embeddability = kappnotembeddable;
Newfile = kappdoesnotsupportnewfile;
Hidden = kappishidden;
}

In addition, after hiding the application icon in the SDK of Series 60 3rd Mr, I cannot modify it back, execute the command to clear it, and the files related to the search SDK Directory project cannot be deleted, in the end, there is no way to display it only when the reconstruction project is changed to a uid program icon. I do not know why.
