    [CR] SQLite Library

    My initial problem was on HOW to store blob data in an SQLite record field using this toolkit. So i thought this was the right place to make my question. I Had no idea about the problem of no standard for storing images on a BLOB field. Now that I know that, i can say: 1)Attached are 2 solution working with SQLite Manager but not with SQLite administrator neither with DB Browser for SQLite 2) Being so, maybe it's better to store images in a specific folder and store the path in the DB. Thank you so much for the support.

    [CR] SQLite Library

    As you suggested, I've made an example using Vision Library, starting from a previously stored image but nothing change. Or better, I don't get any error executing the VI and in the DB I can see the new record but using SQLite Administrator I'm not able to see the picture inside the DB. SQLite Administrator has a specific function that should show the image. I attach even the DB with 4 records with that should have the same image on it but I can't see it. DB_CN35.sdb

    As I told in my previous message, Because I Don't Know How to save my image as a blob in labview! The image is not originally stored in my PC but is acquired with Vision Libraries. So once acquired, Hwo to save it as a blob? And then How to pass it to SQLite library to store it into my DB?

    [CR] SQLite Library

    Hi, i would like to use your library to save images on a field of a table in SQLite. Is it possible? How should I do? thank you so much.
  7. Hi, I'm trying to insert some NULL values in a datetime field. In the example, the DATA_INSERIMENTO field has a non empty value and it works correctly but DATA_INTERVENTO doesn't accept NULL. If I use an empty string instead of null, the VI run without any errors but it fill the database field with a 1900-01-01 and it's not what I want. If I use the DB Tools NULL VI it gives me another type of error, maybe 'cause I'm connecting a variant to a cluster of string. If i use a Variant to Data VI for the NULL value it returns an empty string so not the result I need. If use the string you see in the label at the bottom of my diagram in SQL Server manager, it works correctly. How can I obtain the same result with labview?
  8. I developed an appication to manage a DB. So I need to create an interface that could be accessed from different users that will make different queries on the DB so it should display different results. Is this possible with this tool?

    SHOW a DXF or a DWG file

    Is there a way to display a DXF or a DWG file? Not an interactive control, I need to display them as they are Images. Is to avoid to export bitmap form dxf files only to show the user a reference layout... something like a preview... Is there a way to do it?
