Mar 20, 2011

I need help with the code to make it so when a form loads it will check the Access database for the user and if that user is present, then it will load their selections. Otherwise, if no user is present it will add a new row to the database and display nothing.

Project Using VB And A Database In Access - Check If My Application Requires Access To Be Installed Or Not?

Feb 16, 2012

I'm using VS 2010, and I did a project using VB and a database in Access. The problem is that when I try to put that "application" on other computers, sometimes, is not working. I thought it can be because on these computers they don't have access, but on one computer, is running another app which is using Access and there is no Access installed. How can I check if my application requires Access to be installed or not?

Here is a example of how I did the connection:

Public AccessOLEDBConnString= "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & myfullpath & ";Jet OLEDB:Database Password=password"

Function getConnection() As OleDb.OleDbConnection

[CODE]...

And when I want to have access at the data I'm doing like this:

dim conn as Oledb.OledbConnection

dim sql as string

dim ds as Dataset

[CODE]...

Created An Access Database - Display Items In The Database Base On The Criteria Selected By The User

May 29, 2009

I have created an access database which i want to search with vb.net, I tried a few thing but it didnt work as desired.

Firstly the program is suppose to display items in the database base on the criteria selected by the user. what i've succefssfully done so far is I've added a datagrid 2 combobox, 1 (searchcbo) with the columns in the database and the other (searchcbo1) will autoload the items under the column selected in and a button (searchbtn) but i have no clue of the code to put in the button. i also tried the fill method but that didnt work as i wanted to. ultimately i want a combobox with the list of columns and a textbox to enter criteria and of course a search button.

The searchbtn should act as the "WHERE" sql command, e.g. SELECT EmployeeNumber, Firstname, LastName, Phone, Location....etc FROM CallLog WHERE searchcbo.text = searchcbo1.text And display the results in the datagrid.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'CallLogDataSet.CallLog' table. You can move, or remove it, as needed.
Me.CallLogTableAdapter.Fill(Me.CallLogDataSet.CallLog)

Check Access Database For Datachanges?

Aug 26, 2011

Working in a VB.Net 3.5 WinForms application, and using Access 2003 (JET 4.0) as a database backend through ADO.Net.

I'd like to check the database for changes, before the application decides to refresh the data from the server. Are there any best practices for this, or should I trust the ADO.Net environment to optimise/handle this?

I was thinking of using a limited log on the server, which gets updated by every change. Pulling this log could tell whether or not a certain table has changed data.

VS 2010 - Import Data From An Access Database To Other Access Database

Jun 22, 2010

I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?

User Credential Lookup In VB To Access Database

Mar 11, 2011

I have a program which I am securing with a Username and Password box, in which the user enters their credentials. In the database, the username is a number field (VB would not accept this as a string and was looking for it as Int32). And the password is a text field. I have the form linked to the database by an OleDbConnection with a DataAdapter (DaUser) and DataSet (DsUser). I am using a datarow which I have declared at the top of my code i.e. Public drUser As DataRow. The problem arises when the user enters their username and password.

The following code searches the primary key row of the database (Username)
drUser = DsUser.Tables("User").Rows.Find(txtUsername.Text)
When the Username entered does not exist, I'm getting this error when trying to display on the form the users email:
NullReferenceException was unhandled - Object reference not set to an instance of an object.
I've tried both if statements and try/catch to basically say if the Username doesn't exist... display an error message etc.

Visual Studio 2008 Creating A Check In Form For A Class Of Students With An Access Database?

Dec 4, 2009

Visual Basic Project - Student Check In Form using an Access database backend This form needs to draw information from an Access database containg tables for STUDENT, INSTRUCTOR, and SECTION. These all need to have primary keys and ids. When (the user) clicks on the drop down box that displays all the sections:

{Table Tennis 1, Table Tennis 2, Table Tennis 3, Billiards 1, Billiards 2, Billiards 3}This should populate the listbox or datagrid from the STUDENT table with the Students that have the same SECTIONID as the SECTION selected in the drop down menu above.

After the Student list has been populated (the user) clicks on a student name in the listbox/datagrid and this inserts that student into the CHECKEDIN table that has a datagrid/listbox associated with it.

This is a great project to practice connecting a database to Visual Studio 2008 .net and playing with the data that has been pulled in. You could use SQL instead of Access.

Database - Replacement For Ms Access Db For Multi-LAN User Purpose?

Apr 27, 2012

I have been using access for my applications from over 4 years now. I realize its time to move on now and i need suggestions for a new database. Here are my requirements :should be able to connect it with Vb.net windows form frontend GUI - all database functions such as add/delete/edit/update will be done through the vb.net front-end only.Should be able to place the db on LAN and each client on the LAN can then access the centrally stored db through their individual front-ends.At the most 5-6 users will be reading/writing to the database at the same time , so the database should not crash or slow down Since i come from MS access background, i would like something thats similar to it so that i can learn and adapt to it quickly.Not very important, but i think its worth mentioning. This db will be the main central db for my .net application.My .net application will also be interacting with quickbooks and magento via some apis but ultimately all this data will go to the central db. So just curious, will there be any compataibility issues with the database that you suggest Should handle about 10 tables and around 10k records in each table Should be secure - just that i should be able to lock it up or anyhow prevent it being accessed from anywhere else other than the vb.net front-end.

Lastly, I would prefer it to be free to use if possible but not essential. I realize there are some topics like mysql vs sqllite and on databases, but pls understand i need suggestions for one that will be apt for the purposes i have listed above.

Edit : Just curious - Would i pushing the limits if i still stick to access - i understand access won't be good for multi-user access but i guess 5 users is not much ?

Open Access Database Based On User Input?

Dec 3, 2009

I've been working on an application for awhile that, basically, allows the viewing and printing of a maintenance database. It allows the user to view basic information for the object and then view the maintenance history. My approach for the maintenance history is simply to have unique tables per object since a history has to be kept for each, however, I'm running into a problem in the application that allows the user to view the general information from one DB and the Maintenance history from the other DB.

Say you have Object ID BG1. I can enter the object ID into a search field, pull the data from the general DB and display the data, but I also need it to pull the information from the maintenance history and display. If maintenance history for this object is not found, then create a new table within the DB, fill the columns with the required fields and allow for the user to edit the history.
