VS 2010 Connect To Access Database?

Feb 17, 2011

I want to connect to a mdb file but i have never did that before. i don't know where to start. heard something about ado.net and some other things.

the file is a 2003 access file if i am not mistaken. and it is shared on network. so multiple users (not too many, max 50) will use it at same time. what is the best connection to use? i have to mention that i don't want to use data controls. i want to use sql commands to fetch data and manipulate data on the form controls myself. i know there are various connection ways like strings and adapters. not sure which one is better.

First off, my apologies for being a complete Newb! I have a SQL Express database that I use quite successfully to track my investments in several accounts. I built it myself, it's quite functional, and Im happy with it. The problem is that there are multiple account tables and updating them can be tedious in SQL Server, if multiple purchases and sales in multiple accounts have occurred in a month.

Simple Inventory - Program Using Classes Hard Coded - Database Named "DATABASE" In Ms Access 2003

Sep 29, 2010

I want to create program in vb2008 express with ms access database. Can somebody help me so i can learn how to program using classes hard coded. I have learned vb6 before but it has a big difference on vb2008.

I have a database named "DATABASE" in ms access 2003 and the details are: Table :

EMPLOYEE(EmpNo, EmpName), DEPARTMENT(DeptID, DeptName), CATEGORY(CategoryID, CategoryName), SUPPLIER(SupplierID, SupplierName), ITEM(ItemID, Itemname), ITEMLIST(ItemListID, ItemID, ItemDescription), INVENTORY

[CODE]...

All the CAPITALIZED name are Table and all items inside the parenthesis are fieldnames. I don't know where to start on working on this RECORDS. I was able to understand visual basic 6 a bit, and i am trying to apply the coding to VB 2008 but all i get is errors. I am hopeless now and i need help to be able to start my programs. If someone can give me a sample code, i think i would be able to trace the line of code to be able to understand it. I am currently an inventory manager on the small company i was working with and i like to organize my record by using database.

Which Database To Use For Simple Strings

Jun 15, 2010

I try to keep it short - so far I got an app. which receive, compare and send STRINGs back and forth. Due to the fact that I am not too fit in VB, I realized it via a SELECT/CASE method. But now, I would like to allow user to add new STRINGs from the user plane as well (before it was done by myself). I can imagine, I need a database for it. Which one would do the job best? I need only two columns, where my app. can send a coulmn B string back, after it recognized a column A.

Database - Simple Front-end For MySQL Tables?

Sep 2, 2010

I'm looking for a front-end that's very simple, to access a to-be-built MySQL Database. I actually need it for only one table. I was thinking that the user could search in a way that would ask for values for each field of that table, and give the option of leaving it blank. Then, it would return all the entries that match up with the query.

I know this sounds simple to the majority of the database gurus out there but I am finding it difficult to find anything related.I am using Visual Studio 2008 VB.net winforms application.I have a form which contains a datagridview. what I want to do by push of a button is set the field "OnHand" either to default or 0. The 'either or' is really for you guys. Which ever one works the best in terms of reducing code or functionality is obviouls prefered.Once the 'OnHand' Fields in every record has changed then I would like to save all the data back to the database'This is more than likely very simple I just cannot find anything that discusses this kind of thing.
