I'm am wanting to get out of access dbs and into something more solid, ive heard that sqlite or mysql are great database tools for your applications. I am also looking for a database with a GUi to manage the database more easily and links on how to incorporate the database into my projects, etc. So any links,videos, suggestions i'd like to hear them all.
View 9 RepliesI 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 wish to develop windows mobile applications, preferably using VB (I 've done this in the past with VB6). What do I need to install? All my searches result in information about using 2005/2008 versions of Visual Studio, which seems odd if Microsoft are pushing to use Visual Studio 2010. I would like to use VS 2010. So, can I develop Windows mobile applications using VB 2010? If not, what version of VS do I need and what language should I use?
don't complicate the issue with a load of flannel. I just want to know that I need to install - this, with this SDK, these utilities and write your software in this language (ideally VB).

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 have an application that has an Ms Access 2007 DataBase which runns great if access is installed. Is there any code that I can use in vb that I would be able to run access with out installing it.

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?

View 2 RepliesI have a past experience with visual Foxpro and SQL. Now, I need to build a database with multiple data files (say 100 files), each data file with millions of records, each record with dozens of fields.Then, each data file is linked with other files by using different fields. Primary data is in English. Then there would be a translation of the English data is in another language. Primary data in English is stored in separate files whereas the translated data is stored in separate data files.

I have a connection to an access database, I have used the data sources tool provided because in this particular instance I don't want to do much with it other than display the records (which I can do) and edit them (which I'm haveing some trouble with).I have created a system whereby the database is connected to using the preset tools available like; BindingSource, TableAdapter, BindingNavigator etc.
I also have a button for edit. This doesn't work and I was wondering if anyone could help me with this? I can't really provide any code for this, because I didn't code the connection by hand and the code I have been attempting to use for editting the records in the database doesn't even sort of work.
I'm trying to make a form that allows users to register new tools with the database. I know how to update the sql server with that information, but there's quite a bit of code that accompanies specific tools (which alter labels on textboxes, etc.) Is it possible to programmatically update the software according to information put into a 'add new tool' form without touching the source code?

View 2 RepliesI 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?
