Best Approach To Link App To Access Database?
Jun 3, 2011
How to link my app to an Access database - there seems to be a number of approaches. I can add in my database via the Data Sources tab. Fine if I want to bind controls and view/edit data. But is this the best approach for queries that return an answer that is a different shape to the original table? Alternatively I can connect to the database directly (connection string, etc) and run sql queries. What are advantages/disadvantages of each approach? In terms of flexibility, is the second approach best? Also, does the second approach require the database to be added via the Data Sources tab?

I would like to know how I can link up my listbox to the access database.For example: I have a textbox where I enter a code and a button that says enter and the code has an item that corresponds to it and that item must appear in the listbox as well as any other items that I need to put in the listbox.

I'm trying to link Access database with GridView control.Here's the question: One successful procedure to link database query.
[code]...
However, I got error of "The ConnectionString property has not been initialized." on da.Fill(dt) when running the second time. First time was successful.OK I finally got mistake corrected. I gotta Dim cn As New OleDbConnection("Provider = Microsoft.JET.OLEDB.4.0;" & "Data Source = C:Class.mdb") again to use query instead of once for all queries.

I am trying my hands on VB.net and is trying out a small application which includes a survey form. The form contains radio buttons and when the respondent clicks on a radiobutton, digit '1' should be placed into the relevant field of the database.I have established a dataset and tried doing it but not sure how to do it because the book (How to program Visual Basic.Net by Dietel) does not teach us that

So i'm creating a simple application as an example that is to link to a Access 2007 database.
On my main form i have four listboxes that are correctly attached to the table, I have one for First Name, Last Name, Phone, and School. I added 3 records to the database in Access to see if I could display the records in the listboxes on the form. I found that it was very easy by setting the properties and I have no problem there. I also have a command button that loads a new form for the purpose of adding a record to the database.
Here is my main form (frmMain.vb)...
CODE:
And Here is the code for the form...
CODE:
What i'm looking for is when the user presses the Add button on the frmAddNew form then it needs to close and the new record is listed in the textboxes and saved to the database. Id also like to know all kinds of things i might be able to do with textboxes and databases because i'm trying to learn for a larger project where i'll need to keep track of hundreds of records.
I understand that this is a simple procedure, but i've been spending all night scouring tutorials and getting lost in the msdn library online, so maybe some human input will be better.

I am working on a project that requires us to create a bracket type tournament and I am now stuck. I linked my access database to my project, and have 32 labels (lbl1-lbl32) and I cannot figure out how to integrate the labels to read from my database. It can be random or not, I just cannot get the labels to display the names of the fighters.
After the labels are integrated, the next coloum of the bracket has a link that opens a new window with each of the fighters match results, does the link have to include anything particular to display the attributes from the database?

I am writing a program to assist Paramedic students in learning the Drugs that they have to know in order to pass their classes. I have created an Access database to hold all the information on these drugs, but not every student that will use this program will need to learn all the drugs contained within this database.
Right now I have 43 drugs in the database and still growing.
What I want to do is to present to the student the drugs and have them say "Y" or "N" as to whether its on their required list to learn. That way they only work on the ones that they need to.

There exists a database that holds information on each planet in the solar system. The database has multiple tables.The program intends to access this data to display it to the user in a variety of manners. The program does not intend to manipulate the data at its source, though calculations on two fields may be performed to determine certain display characteristics.What is the optimal method for accessing the data?My initial approach, (read: gut feeling, no research) was to take each related row of data from the database and create an object of a custom class based on the data. So you might wind up with:[code]Then use these objects to perform whatever actions the program needed to. I ran into a lot of problems trying to implement this, so that I believe my design approach is fundamentally flawed.

I have browser control in a winform application that navigates to a secure intranet location. In the web application that sits in the browser are several links that bring up other windows outside of the browser... like dialog type browser windows that may contain information like user information... etc.
When I run the application in a regular browser, it runs the new window perfectly but when I click on the same button link in the web application, it brings up a windows with no data saying that I don't have access to the server.

I have two Access database, say database One.mdb and Two.mdb. I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time. I can think of a way by querying the table to a dataset and then delete everything on the other database before filling the table in that database with the dataset

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?
