SV: Valentina Digest, Vol 118, Issue 9

Fri Oct 19 18:07:19 CDT 2012

William & Ruslan,

Thanks for the input. Yes, I have only intention to work with local
dbs (that's cover 100 % of my clients' needs)

I will polish up my solution and then will I make a blog entry about
it.

The only outstanding question is if it's possible to populate a
combobox control without iterating through the collection?
My understanding is that it's not possible as we don't have Dataset as
part of the API model.

Kind regards,
Dennis

Have they open any SDK for developers?

About 2 months ago when I asked,
They did say ,e no SDK yet.
I have hear that development is expected on Silver Light  (.NET) ?

1) VNET contains a lots of API_way examples.
Have you try learn them?

2) here you can find PDF, which have the same as WIKI, But really
adopted to NET syntax

<http://www.valentina-db.com/docs/dokuwiki/v5/doku.php?id=valentina:pr
oducts
:adk:vnet:vnet>

3) in short.

API should be used only if you work with local db.

You operate with help of
  VDatabase + VTable + VField +  VSet/VBitSet/VArraySet

Instead of 
   Vdatabase + VCursor + VField

** You need look on Vfield class, it has many search funcs

   Vset res =   Vfield.FindValue()
                               .FindRange

So you get instead of cursor some Set of records.
Can be used BitSet and ArraySet.
In wiki there is description of difference.

>From set you get RecID of a record.
Then use 

 tbl.RecID = foundRecID

And then you read fields like in cursor

Loop by fields
{
        fld = tbl.Field( "name" )
        string s = fld.value

        show in form
}

Hi Frank,

What are the reasons why you should only use it for local database? Is
it because collecting that much data over an internet connection takes
more time?

Right.

Especially for multi-table walks.

For example, SQL make join of 2/3/4/5/.. Table on server side.
Even for million records.

With API, you need send may be millions requests to server.
