ListBox Update As Data Added To Database?

Jan 15, 2012

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.

VS 2008 SQL Server - Notified When A New Entry Is Added?

May 15, 2010

I have a VB.Net application that connects to a SQL Server database on my web host at GoDaddy. I'm wanting to use it for a chat program so that users can add messages to the database and then everyone else gets the new messages when it re-queries the database.

The only problem is that the only way to get the new messages is to re-query the database every # seconds.

Is there any way to have my program not re-query the database until an entry is added by another user?Would the SQL.SQLNotificationRequest be used for this?

Refresh Listbox With A New Entry?

Nov 4, 2010

I have a reporting utility for my users to view, send (via email), export SSRS reports. I have set up date parameter boxes with calendar drop down and they are able to send via email a URL link that would either display the report via ReportViewer or send a link via email (listbox of email addresses) that would let them view the report in Excel or PDF. This is working just fine. Now I just added a button for adding new email addresses and a new windows form with a textbox for entering the email address and a command button for Save Email Address. I am able to save the email address just fine from the small pop-up window for entering the email addresses but after closing the window, the listbox of email addresses on the main form does not get refreshed with the new entry from the textox even though the SQL table EmailAdresses got updated.[code]...

VS 2010 Listbox Data Extract After Entry & Sorting?

Sep 26, 2011

I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.The code that I am using for the Device response capture, etc is :-

*********Code Start
Private Sub btnPoll_Click(ByVal sender As System.Object, ByVal e As_ System.EventArgs) Handles btnPoll.Click

Update With Datagridview When Combobox Added

Jan 7, 2012

I had a functioning datagridview that was created from VB2010's datasource by clicking on a table, picking datagridview and dragging to a form. I changed three of the columns of the grid to comboboxes bound to different tables. If I change a value in a column (not a combobox column which still shows the value from the original table), I receive InvalidOperationException was unhandled on Me.TableAdapterManager.UpdateAll(Me.MasterDataDataSet). What code do I need to add if I change columns to comboboxes?

Insert New Picture And Added Into The Listbox?

Jan 14, 2009

i am using visual studio 2005.I have a few questions about listbox and openfiledialog, hoping to have some answers.I am creating a picture viewer, and so in my listbox I have put 3 defaults pictures, say namely 'X', 'Y', and 'Z'.Then there is this Insert button that allows user to insert new picture and added into the listbox.So here comes the questions:1. In the Insert button code below, I have made it such that whenever a picture is insert, it will displays out the picture in the picturebox and its name in the listbox. So how do I make the listbox to move its highlight to the newly insert picture?

Private Sub btnInsert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnInsert.Click
OpenFileDialog1.FileName = ""
OpenFileDialog1.Filter = "JPEG | *.jpg"
If OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
MsgBox(OpenFileDialog1.FileName & " has been added into playlist")
ListBox1.Items.Add(OpenFileDialog1.FileName)

[Code]...

3. Lastly for the openfiledialog. As a new picture is insert, the name displays in the listbox is 'C:Documents And Settings......' which is the location of the file. Is it possible to limit it to displays only the filename, and not the location?

I currently know how to click a button on the application and when I click it, it invokes the OpenFileDialog Event or Object.

Parameter Update Reports 1 Row Updated But No Data In Table Added

Oct 13, 2011

I am getting an incorrect repsonse after an update to a table. In my RowUpdating event I have the following code which builds an Update Parameter to call an SP to update a table. I must be doing something wrong but everything runs fine. My rowsAffected variable reports 1 after the update, but the table never gets the data.[code]I found a solution that is working. On the original DataSource for the update command I needed to add the following.[code]This in essence allows the original data source to call the SP. Note: that the command type needs to stay as TEXT not Stored Procedure as one might think.
