Question about RMS -- MIDP1.0 & MIDP 2.0

[bennet_chen]

Hi,

I have a question.

The code is:

String[] RS_AName = RecordStore.listRecordStores() ;

At MIDP 1.0, it is ok. ( Nokia 7210 MIDP SDK 1.0 )

At MIDP 2.0, it returns null. ( Series 60 MIDP Concept SDK Beta 0.3 )

How can I do to read RMS name at MIDP 2.0 ?

bennet_chen, RTFM

listRecordStores
...
Returns:
an array of the names of record stores owned by the MIDlet suite.
Note that if the MIDlet suite does not have any record stores,
this function will return NULL.

I would rather be surprized that Nokia 7210 MIDP SDK 1.0 returnes not null
Probably you already stored some data there

doctordwarf,

Thanks for your help.

I have a program, read some data , and save into RMS.

In MIDP 1.0, It's ok.

In MIDP 2.0, I can see the file in my hard disk, but I can not read it out. (appdb folder, these files like run_by_class_storage_#M#A#D#O#Info.db)


Please help me to solve the problem, thanks.

I am developing for MIDP 1.0 currently, so my advices may not work in your case.

However I just tested my game on Series 60 MIDP Concept SDK Beta 0.3 (used other emulators before) and it perfectly stores and reads to/from RMS. I can also see these files on harddrive.

Why do you need listing RecordStores at all?
I don't think you use different store name all the time.
Try using RecordStore.openRecordStore()

doctordwarf,

In my case, I really need to know all of these RecordStore names. Thanks for your advice, but it dont work for me.


Please help me to confirm the RMS:

My Code is :

rs1=RecordStore.openRecordStore("MADOInfo",true);


And on my harddrive, I can see the filename like

" run_by_class_storage_#M#A#D#O#Info.db "

Is the filename right ?
Or, I need to change the filename to lowercase letter?
