Getting Number Of Rows In Table To Display In Database

Aug 23, 2009

Any method that can effectively get the total number of rows that is StartRows to EndRows in a database table and then get the corresponding data from that row as currently I am having difficulty in retrieving out the correct row of data to the column that I am comparing. It will always get the first row of data regardless of which row I put in the handphone number which I'm comparing to. The codes below is the one which I am currently using now to detect the maxrows in the database and also to retrieve the corresponding information.

MaxRows = ds2.Tables("CustDetail").Rows.Count
MaxRows = MaxRows - 1
Dim numbers() As Integer
Dim EndAt As Integer
inc = 0
[Code] .....

I used a msgbox(n) to see the number of rows in the database but it displays only one where I have two rows in my database. The for loop is the one which will detect the number of maxrows and also retrieve out the corresponding details. But apparently this is not the appropriate way.

Select And Display Matching Rows From A Table?

Apr 22, 2010

For a project i am working on, i am taking bookings. These bookings are stored in a database alongside a users personal details. The personal details are assigned an ID according to the user who booked it. A user can book more than once with different personal details.

My problem is that i want a user to be able to edit a booking. I want a list of all the names that user booked to be listed in a combo box. This is the part i am having trouble with. i am using an access database and using sql statements to pull out the data. This is what i have tried so far:

SELECT [First Name]
FROM PersonalDetails
GROUP BY [First Name], UserID
HAVING (UserID = ?)

If i execute this query in the query editor, it works and shows the two records currently assigned the input id. However, if i try to output this to, for example, a text box, then it remains blank. I am assuming thisis because there is more than one output, but i'm not sure.

ListBox - How To Display Pictures In Table Layout Panel

Apr 29, 2010

I have a listbox populated with peoples names. When I click on a persons name in the listbox, a datagrid will unhide itslef, connect to a DB, and list all of the pictures that person has. All the pictures are stored on a drive in a folder named after the person. i.e.
Greg Palinkas has 52 images stored in F:PicturesGregPalinkasImages.

I would like to display all of those pictures in a Table Layout Panel populated by the choice I made in the listbox, so if I select Greg Palinkas, the Data Grid is pupulated with the names of all the images i have, and the Table Layout Panel is populated with all the pictures I have in my GregPalinkasImages folder. I have got the Data Grid updating and running smoothly, but am lost as to how to get the images to come up.

VS 2008 : Display A Value From Data Table To A Listbox According To A Condition?

Jul 28, 2010

My aim is to choose a value from Listbox1 and on Listbox2 I would like to display the corresponding value from a table in my database. I mean, when I select Product A from Listbox1 (which is getting its values from row "Model" in my database table), I should see its price on Listbox2 which is available in the "Price" row of the same table (and also manipulate this price in different places for calculation etc.) . I am not sure if the best way is using "databinding.filter".

Here is the code I have but I cannot making it work:

Dim dtCOP As New AmetailorDataSet.COPDataTable
Dim adapterCOP As New AmetailorDataSetTableAdapters.COPTableAdapter


A small note: my aim was using a Richtextbox instead of Listbox but I am told that Richtextbox is not suitable for using with datasources.

Cannot Display Database Selection In Listbox?

Aug 24, 2009

I am doing a lab where you have to connect to the database using the Database Configuration Wizard in Visual Basic (Visual Studio 2008). The database connection is there since the form will display the records.The problem is the user is supposed to be able to click on the combobox arrow to select a stock rating (high, low, etc) and then the listbox will display only the stocks with that rating. I thought this would work but nothing is showing up in the listbox.

Database / ADO.net & Displaying Table Entries In A Listbox?

Jun 20, 2010

I just starting coding in VB.net about two weeks ago so I'm still a begging and I learn best by seeing working code and then adapting it to my situation. That being said, I need help displaying table entries in a listbox. I've successfully created a database in my test application, added it to my Data Sources and used a drag / drop method to add Datagrid View & Details (labels & textboxes) to my application for testing purposes. Now I want to try and display table entries in a listbox.

Example Database:Table: Contact
- ContactID (autonumber) [primary key]
- FirstName (text 50 limit[code]....

Also is there any benefit or down side to creating a database in MS Access, create the relationships & tables, then attaching that database to my application or is it better to create the database in the application like I did in the example above by using the Add New - Service-Based Database option?
