File types and dependencies

in
Keywords:

The picture below shows the dependencies that exists between source files in a typical Symbian application.

files.png .hrh files contains enumerations that are used in .rss, .h and .cpp files. The typical content of such file is the list of commands that are defined in the application menus, toolbars, etc...:

// MyApp.hrh
//
enum {
   EMyAppCmdOpenFile = 0x6000,
   EMyAppCmdEdit,
   ...
};

It is a convention to use values from 0x6000 and upwards for these command IDs.

.rss files are resource files. These files contain the definitions of all static strings, buttons, menus, lists... used by the application UI. The Nokia Series 60 wizard also defines a .loc file type which is very close to .rss but can specifically be used to declare all static strings of your app. It is then easier to localize.

.rsg files are generated resource files. They are created at compile time by the resource compiler. They shall be included by .cpp files to handle resources.

.mbm files are Symbian bitmap files. An overview of these file format is presented there. A particularity of this file format is that several bitmaps can be stored in a single file.

.mbg files are generated by the toolchain when creating the .mbm. These files are typically included by C++ ans RSS files that uses bitmaps. A mbg file contains an ID for each bitmap within the corresponding .mbm

how do I generate the rsg and mbg files.? I am trying to generate them for the listbox example. The VC++ compiler generates error "aknexlist.mbg: No such file or directory". Thanks

*.mbg files can be created by *.mpp file (and ListBox example has this feature in it's *.mpp file), but at least I had to run 'abld build wins udeb' first before 'abld makefile vc6' to get it done.

I'm having problem when trying to create a dll with a resource file(own common dialog). Dialog builds up fine, but when I'm trying to use it in application it crashes when trying to use the dll's resources. Any idea how to do this, or is it impossible?

Hi,

In case of a DLL you have to load your resource file manually. Use CCoeEnv::AddResourceFile for this purpose.

Check the rcomp utility on Symbian web site. It contains the source code of the resource compiler.

TOS 4.0 and greater will support the older format and a new extensible format of the resourse file.

It is a binary file created after building process. After building process every Application has got atleast two files called .app and .rsc

.rsc is build from .rss

You can find this .rsc file from the following location

your path where u loaded symbian os for e.g

C:\symbian\series60_2.1_cw\epoc32\release\WINSCW\UDEB\SYSTEM\APPS\your application name
