how to set record index value to initial or zero ?

[maaz4]

I am deleting records from RMS for first time it is deleting fine. But when I am deleting record for second time the function is throwing an exception

javax.microedition.rms.InvalidRecordIDException

That is why I want to reinitialize record ID index to zero to avoid this exception.

I will be thankfull if anyone will explain me with code or example.

Thanks in advance.

Hmmmm.... why on earth do you want to delete same record twice? One time is enough. Then it is is gone and if you try to delete that non-existing record another time, of course the system alerts you...
Do you have a good reason to delete it twice (or more times)?

Of course you could always place the record deletion inside a try-block and handle the exception there. However be careful with that approach, as then you might end up in a situation when that exception is thrown for a good reason and your app should behave differently instead of just not reacting to it...

Hi Hartti,

Actually I don't want to delete same record again and again. I have to delete the different records. But for first time it is working fine and all the records are deleted. but when i press delete button again the the exception is caught the reason is due to the record id is not initialized as the records deleted before were starting from index id - 1. but after deletion the index id is not initialized. can you help me with some code or example ?

In one post i read that all records should taken in a vector and deleted. then the records will be inserted in RMS from Index id-1.

this is the post kindly make it easy for me http://www.developer.nokia.com/Commu...ecord-deletion

Hi maaz4,

The exception is thrown because you are trying to delete a record that doesn’t exist.

Here’s a link for sorting records in RMS that might help you to solve your problem.
