RMS Update issue

[rajan701v]

Hi everyone!!

Could any one solve my issue...
I have created an LWUIT table in which the records are fetched from the RMS. when i update the records it will update the records but when i am exiting the application. and opens once again. that particular record hides from the table.

One more thing when i use rs.getNumberRecords(); it will give total records including the hidden record..
What this all is happening i am stuck..

Please reply,
It's urgent..

Apolozy,
Commit method is not for RMS.

Are you Properly closing the RecorStore after writing the Data.

Hi everyone !!

When i am updating the data in RMS , the value is updated but all other values got null.. is this the issue... because when i use rs.getRecord(int id), after updation. the out of 10 fields the values of 5 are updated and others are saved as null.

Why this all is happening...

I want to update 5 fields out of 10 fields in RMS... how this is possible...

Please Reply

Cut&paste your method where you are trying to update the record store, are you using set Record or adding new records and removing the old ones.

I am using setRecord method to update the record..

Now, i copy the data which is previously saved, in other variable before updating the record and using these values while updating the records.. i.e. i have used 5 old values and update the record with these 5 values and 5 new values out of 10 values.

One more thing i want to know, how can i fetche the updated record at runtime... i'm confused. i have used re.enumerate("","",true);
And also used re.keepUpdated(true); But nothing happens..
The thing is after updating the record in rms i have to show the updated record in LWUIT tabular format. but it is showing the previous value(not updated value). But when i am calling the same according to rs.getRecord(int id); it is showing the updated record.

Please reply soon............

Thanx in advance rajan

I would not use the setRecord method, because it makes problems like you have. I would completely delete the RecordStore, and would write it again (instead of update). I got the same problems you have, when I used setRecord method, and for this reason I completely delete the RecordStore, and create it new.

You should only use 2 methods, writeRS and readRS, for example language settings:

    public void writeRS(String language) {
        try {
            RecordStore.deleteRecordStore("Language");
            RecordStore rs = RecordStore.openRecordStore("Language", true);
            rs.addRecord(language.getBytes(), 0, language.getBytes().length);
            rs.closeRecordStore();
        } catch (RecordStoreException rse) {
            rse.printStackTrace();
        }
    }

public String readRS() {
        String language = "English";
        try {
            RecordStore rs = RecordStore.openRecordStore("Language", true);
            if (rs.getNumRecords() == 0) {
                rs.addRecord("Language".getBytes(), 0, "Language".getBytes().length);
            } else {
                language= new String(rs.getRecord(1));
            }
            rs.closeRecordStore();
        } catch (RecordStoreException rse) {
            rse.printStackTrace();
        }
        return language;
    }

The standard language is English (first time you start the app e.g.). If you change the language, it will completely delete the RecordStore("Language), and write it again.

AND DANGER:
If you want to get a String from Byte, use: myString = new String(myByte) instead of myString = myByte.toString().
myString = myByte.toString() does not work for me...

Thanx for the reply guys...

But,
I think this may be the issue...
I am opening all the recordstore in startApp();
And closing all the recordsStore when exit the midlet..
May be this way i am not getting the updated value at runtime...


Please Help..........

Changes in RMS only take effect, if you close the RMS.

It would be easier for us, if you post your sourcecode. You can also change it into pseudocode.

@rajan701v
Pseudocode is your code written in your own words, f.e. like this:
OPEN RS
FOR i
ADD value1,value2,
CLOSE RS

Have you tried what iw wrote in #10, without setRecord method?
