Sending Application in Background using RSS

Add the "Launch" field in application info resource in your Project .RSS file

RESOURCE APP_REGISTRATION_INFO
{
    app_file="projectname";
    localisable_resource_file="\\resource\\apps\\projectname_loc";
    hidden = KAppIsHidden;
    embeddability = KAppNotEmbeddable;
    newfile = KAppDoesNotSupportNewFile;
    // Launches the application in background.
    launch =KAppLaunchInBackground;
 
}

Why we require to launch a application in Background ?
One use case may be the running wallpaper where a server with GUI runs in BackGround.
