Android Question Doubts regarding KeyValueStore and its Value updates

[Anser]

Hi,

1. I would like to know the best way OR the expected way to update the VALUE of an already existing KEY in KeyValueStore database.

• Should I delete the Key and its value first and then Create a new Key and the New Value using kvs.putsimple / kvs.PutEncrypted ?
• For eg.
  
  If Starter.kvs.ContainsKey("SmtpDetails") Then
      Starter.kvs.Remove("SmtpDetails") 'Remove, if, already exists. Then add
      Starter.kvs.PutEncrypted("SmtpDetails",Starter.MapSmtpDtls,"MyPassword")
  Else
      Starter.kvs.PutEncrypted("SmtpDetails",Starter.MapSmtpDtls,"MyPassword")
  End If
• OR Can I directly update the store without deleting the Key first ? Will this method update the value of the existing key ?

1. Can I store a Boolean Value in KeyValueStore ?

• If yes, then is the following the right way to do it
  
  Dim IsAutoLogin as Boolean
  IsAutoLogin = True
  kvs.PutSimple("AutoLogin",IsAutoLogin)

Regards

Hello,

You can use put for the existing one. It will update the old entry. You dont need to delete and add each time.
I never tried if it stores boolean but it take 2 min to try it. You can try it and see.

Note that you are using the old version of KVS. You should switch to KVS2: https://www.b4x.com/android/forum/threads/b4x-keyvaluestore-2-simple-powerful-local-datastore.63633/

Erel,

I am using KeyValueStore: v2.00

 

[Erel]

There is no PutSimple in KVS v2.

Sorry. Its my mistake.

In the question that I used in the post #1 of this thread, I have used kvs.PutSimple("AutoLogin",IsAutoLogin).

In my App I am using kvs.Put("AutoLogin", AutoLogin )
