I have a form where i can enter new product. In that same form i have listbox where i show the current product from the database.
I want to know how to update that listbox as i enter new product into the database so that user can see the current content of the product table.
my code to load the listbox
Try
Dim ds As New DataSet
Dim cmd As New OleDbCommand
[Code].....
To sum it up, what i want is something that will refresh the current display of the listbox so user can see the actual and updated contents of the database.
with the above code, the newly entered product/data can only be seen when the program is closed and reopened again. Which is not very convenient.

I am building a program that does inventory control. I have multiple forms connected to same database. One of the forms I have a search function. When I was using the controls at the top of the page, it was working. I added buttons for the controls and now the database wont store anything. I can open the input form and I can add multiple inputs, close the form, open it back up, and nothing left in the database. I have also noticed that my database icon in the data source has a small red X in it. When I click on the icon, it is showing the db as closed. I can refresh it and it opens, until I run the program and it closes.

I'm trying to create a simple Data Grid that will automatically save changes. So far I have a data grid connected to a MS Access 2007 Database that reads the data. I can create new fields in the Data Grid, but I need to program to save the data automatically to the database on update (or on close).

I do not have any code to show, but using asp.net, vb.net, and SQL with stored procedures.If on a page I have an item that is added to the database and therefore that information is "saved", is there a way to have an ("exit without saving") button on the page that does away with those changes?Using infragisitcs ultrawebgrid, you add an item to one table. You can add an item to another table on that page. i assume adding these items to the table automatically saves in the database. There is also a text box but without clicking save I do not believe that those items are actually added to the database. Update panel is used, I don't know if that matters.
If after someone adds to the table but then decides.. oh wait.. I don't want to do this just yet, is there a "one-click" way to act as if I never visited that page to add info? I'm assuming it would be deleting the entries but this would have to be limited to deleting ONLY those items added while making... we don't want people adding info, then going back and deleting once the "save" button has been pushed.

I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.

We have a .NET 2005 windows application that gets its data from a central SQL server. There is a web service that is exposed to other applications that allow the external programs to add data to that exisiting database.
Is it possible to notify a user in the Windows application that a record has been added using the web service?
SCENARIO User A: In windows application viewing all personnel
User B: Adds new personnel record via web service while User A is still browsing in the window forms application.
Is it possible to have User A notified of this change?

I'm working on a simple data logging program, and I have little to no database experience. I wrote a little VB forms app to log the data to ms access and then graph the data, but I'm having trouble with adding records to the database. First, I created a simple one table database in access. Then, I added the database to the project as a data source, and gave it a data set using the wizard. Right now my code looks like this:
[Code]...
There are no problems during build or run time, but I do not see changes to database after the program runs.

I am creating a datatable and then adding a column to it which is filled with data from existing column and parsed into correct format DateSold is my existing column from my datafile and I create NewDateSold by adding the column to the existing table and then parsing the information in date format.
This is added to a binding source which then is used to populate a combobox I want to be able to sort the combo box by NewDateSold Desc I was able to this on the original column by simply using the "order By" in my query, it seems now that I added new column it is no longer sorted? I am finding different solution such as using dataview and wish to know the best way to do this

Hi how's it going. In the middle of coding a banking application for a project. Part of it involves mortgage interest repayments. Was wondering if there was any way of logging the time a new record was created and added to the database and then adding interest to the balance owed periodically every 30 days..
