I am using SQLite ADO.NET Provider.
I want to create a database with 2 tables via code in vb.net .
Please provide code for the same.
I am using VS 2010 Winforms, working under XP SP3 Pro
I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand
CODE:.....................

View 1 RepliesI have two Combo-Boxes like this
I need to create an auto-fill feature for the 1st Combo-Box. It should list the EmployeeID if Search-By Field is specified as Employee-Number. Similarly it should list Employee First Name along with Last Name if the Search-By Field is Employee-Name.
How can I do this? I have no clue, I am doing this for the first time. I am using SQLite, Visual Studio 2010.
Dim mySelectQuery As String = "SELECT " & Search & " FROM EmployeeTable WHERE Status LIKE '" & Status & "'"
Dim myConnString As String = "Data Source=" & Application.StartupPath & "DatabaseSimpleDB.db3"

I am writing an app that uses both an SQLite and MySql database. The reason for this before you ask is that it means I can store a local copy of the data onto my user' own machines when they are offline, and then update them to a central server when they are next online.
The problem I have is that when using datasets (on tables created in identical fashion) the itemarray of the mysql database has 9 extra totally blank fields...where as the SQLite itemarray has only the values for the items.
here is a snippet of the code:
CODE:
ultimately I am getting an index size mismatch error but with both tables having the same number of fields this is confusing.

I'm writing a program that needs to parse data from a SQLite Database, I have the reference DLL but I do not know the proper syntax for the actual parsing of the file. The reference I have is located at [URL]..I don't really see any code that would need to be given seeing as the code for that class is currently something link:
Imports System.data.SQLite
public class SQLite
public sub Retrieve_Data
end sub

View 3 RepliesI am using System.Data.SQLite with VB 2010 to bind to a SQLite database. Everything works just as it did in VB2005. I drug a table from the DataSources Window onto the form and automatically generated the binding navigator, table adapters, etc. I can preview data in the TableAdapter but when I run the app no data is read into the grid. The same thing happens with the details view. The BindingNavigator shows 0 of 0 records. There are 27 records visible when I preview the data. The code follows:

i'm just starting with sqlite, as apparently its quicker than access for a real time logger. i'm using this as a tutorial - i didn't install the runtime support with SQLite as it causes issues when using 2008 express.[URL]..
but it seems the data isn't being written to to the db. i can't tell exactly because i dont have a program to view the table contents, only to view the setup of the db.
I created a small program which one uses the SQLite database. I have a simple table employees, composed of the name and password. I can not write sql script correctly. application code is:
Imports System.Data
Imports System.Data.SQLite
Public Class Form1
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click

I am trying to retrieve a password from an SQLite database. The id of the row the password is in is 1. I want to assignt his password to a variable called actualpass.[code]
View 1 RepliesI am accessing an sqlite database file from my VB.NET application.Currently, I use Try... Catch when opening the connection to the database, however if the database is locked by another application, it will take 5-10 seconds to throw the exception which says that the database is locked.
So I want to know if there is a way to test if the database is locked before I try to open the connection... because the long 5-10 second pause is annoying.
The situation is this. I have an application written in vb.net. it consists or two parts. One on a PC and the other on a handheld windows mobile 6 device . The desktop program transfers a SQLServer compact database to and from the handheld device using activesync via USB. Potentially we want to look into having android handheld devices also supported by this application. Now I know I can use SQLite with .net. I know I can use ADB to push and pull data (and therefore the database files) to and from the device.
What I need to know is can I access ADB directly from VB.NET as an API or SDK rather than having to do it manually.
Unless of course I'm missing something and I can copy databases to and from the device in some other way?

Is it possible to Create a New table in the Database using any Action. The application I have designed is based on DateTimePicker. Is it possible to Create a table "March", "April" so on, when the user selects March or April for the first time. So that records of that particular month will be updated in that particular table.
