Android Question If Starter.kvs.ContainsKey("key") ==> "missing parameter"

[FERNANDO SILVEIRA]

Hi there!

I'm trying to check for an existing value stored before using it, according to the tutorial documentation, but the IDE points me a missing parameter.

If the value is not stored I'm going to PUT it then.

Any clues? BTW, the process was started on

[INDENT]Sub Service_Create
    kvs.Initialize(File.DirInternal, "datastore2")
End Sub[/INDENT]

Regards,
Fernando

If Starter.ckvs.ContainsKey(user,key) Then
      
End If

'User as String
'Key as String
'THEN key word

 

[FERNANDO SILVEIRA]

Thanx for the reply but tutorial documentation don't state user, only key value.
What should I put in "user"?

'Tests whether a key is available in the store.
Sub ContainsKey(Key As String) As Boolean

The answer is in this tutorial.

Are you using CloudKVS or KVS2?

 

[FERNANDO SILVEIRA]

Are you using CloudKVS or KVS2?

I'm playing with local KVS and relying on local KVS tutorial.
So, probably I'm using the wrong set of libraries.

:-(

I'll look thru it, but mine is a more modest project with local store for now.

Thanx.

Brothers, Brothers, Brothers,

I can't believe you have all been caught out by this one - very, very obvious.....

If {Statement} THEN
Do Something
Else
do Something Else
End If​

So instead of:

If Starter.kvs.ContainsKey(Uber)​

it should be:

If Starter.kvs.ContainsKey(Uber) THEN​

Don't worry - it happens !!

Enjoy your Coding

*LOL*
Man, you got it!
Thanx a lot...

Now let's see which the near steps brings me...

I saw. I wrote above.

'User as String
'Key as String
'THEN key word

Next time I will put a banner and arrows.

If he posted his code as text instead of a screenshot with a smorgasbord of colors, it would have been a lot easier to detect and someone would have delivered the correct answer immediately. That is why @Erel always recommends putting your code as text not a screenshot.

In fact he GOT the correct answer in Post #2

FIXED!

Lessons learned with this 1st complete application:

1. To double check the syntax (even the most elementary)
2. Reuse of stored data (KVS2)
3. Use of tabs
4. Use of RadioButtons
5. Use of mailto to the default mail program
6. Use of code /code [] tags when posting a thread

BTW, I used to be a good Basic/VB programmer in the past, now I'm trying to recover my former status.


Thank you all...

That is true, but Fernando did not pick up the correct answer until post #9

Lessons learned with this 1st complete application:

One additional thing to add to your list:
7. Never use a screenshot to post code. Use text so members who help you can manipulate it. Errors are a lot more detectable in text.

That's true.
You were pointing the Moon and I was looking to the finger.
