DB/Reporting :: Populate Listbox With Objects?
Apr 24, 2012
I am writing a database using OOP, i have created my classes ect and i am able to input data.
I have four textboxs, and two listbox's. The first listbox lists all the categories which i have managed to do. Now when the user selects a catelgory a list of objects under that category are listed in the second listbox which the user then selects to display any related data and this is the problem i am having.

I'm connecting a MS-SQL remotely with VB2008 Express.I defined two different methods - the first one is copied from my old VB6 application, which is working perfectly.In this application, the retrieved data is added to a listview control, not datagrid!
Code:
Dim myconn As ADODB.Connection
Dim MyRecSet As ADODB.Recordset
myconn = New ADODB.Connection
[code]....
The SQL query contain several table, thus I used a "*" instead for the table name- not sure this is correct?
Code:
da.Fill(ds,"*")

I have a database in ms access. I am trying to use a listview to populate this database. I have comboboxes and textboxes that populate the listview. I have tried to just make sure that my database will populate with the combo boxes before I try to code it to populate from the listview. I am running into an error while trying to populate this database. The error I am receiving is the following,
Syntax error in INSERT INTO statement.
The error is occurring in the da.update(ds, "TrapDatabase") line.
Code:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim con As New OleDb.OleDbConnection
Dim dbprovider As String
Dim dbsource As String

Probably a very dumb question but I have a program whereby I create and populate an in memory datatable, which I then add to a data-set. I then run a couple of updates on the dataset and need to know how to then send these updates down into the in memory datatable :Here is a mock up of the code structure following the creation and population of the table :

The DataGridView Control only accepts one data source, but there are ways to brake through, ways that I'm not able to find.

I have an Access Database that contains two tables. I would like to populate 10 text boxes on my form with the data from the tables. For example: Table1 has a list of names 1 thru 5 and I would like to have 5 text boxes on my form when the form is loaded to populate those names. I know how to populate a combo box with the information, but not sure how to do it into individual text box
Current Code:
'create connection and command string
Dim conStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data

I have a Report I created with Visual Studio's VB.Net ( I guess this makes my report embedded), which I can select a date range like starting and ending date but the drop-down listbox for the Name is empty and I have to type a name into it to work. I need to be able to choose the name because I won't know who is on the list.

I've given up on my harder stuff and have simplified it to something else. There are no errors that pop up now but the list box doesn't populate! I took the code from a book and there's a data adapter, data connection, and data set on the form already (they're not named in this code though, since the book didn't say to). When the program opens, the list box has a line of text in it and the list box doesn't fill with the right items.
Private Sub EditStock_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Try
Dim dsitemlist As New DataSet
Dim itemlistadapter As New OleDbDataAdapter _
("SELECT ItemName FROM Stock", ConnectString)
[Code] .....
And here's what shows in the box.

I come from Access and I am developing now my first windows form app in visual basic 2010 based on a Access database *.mdb. The thing is i have an access db with 5 tables. I have created the forms, connected to the database, all is working great. Parent- child relations are working, datagrids and comboboxes populate the right way, buttons are working.
But now I want to populate listbox, and combox from tables with queries. Like in access I would like, for example to populate two different listboxes bound to the same table with different queries, so that the listboxes give different results, based on different variables or textboxes.
But I don't know how to attack the problem: the query works against the tableadapter, so the info it gives back is always the same. I have tried to duplicate the tableadapter of the table i want to query, writing different sql queries in both, but it does not seem to work. I don't know in what direction I should ivestigate: LINQ, sql queriess, coded queries, filtering the listbox...

I'm trying to populate a listbox with every file that was last accessed more than a year ago but I've hit a snag, i cannot get the fileinfo for some files because the path is too deep, is there a way round this
Dim drivestring As String = lstBoxDrives.SelectedItem.ToString
Dim directoryName As String
Dim fileName As String
Dim accesstime As Date
Dim FileProps As IO.FileInfo
[Code]...
The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

I'm doing a win form application in visual studio 2008 and using 7 listboxes where my sql query will populate all customer from customertable. It's 7 cause it's one for each day, my problem is to get customerid when I select one of the customers from any of the listboxes to my textbox. Since there are 7 listboxes I can't use "data bound item" function, in that case it would be easy to write code like this: textbox1.text = listbox1.selectedvalue.tostring(

I am trying to populate an array from a listbox.My listbox items contain something like this:
1 for January
10 for February
3 for March
I have code in place and it was working, but I am taking the first character of the listbox item to populate the array. If the value of the listbox is 10 for February, I need to get 10, not just 1. Can I do something with the string that says I want to trim everything from the space to the end? Since they are all formatted the same way, if I could trim out anything from the space on, that would work.
Here's what I currently have:
ReDim m_adecRainfall(m_astrMonths.Length - 1)
For intCount = 0 To m_astrMonths.Length - 1
m_adecRainfall(intCount) = CDec(lstMontlyRainfall.Items(intStart).ToString.Su bstring(0, 1))
intStart += 1
Next

I'm trying to get a listbox to populate a list of processes that are neither running nor in the "blocked" list. This code is in a timer, so it also checks if the process is already in the list.
For Each proc In Process.GetProcesses
Dim allowed As Boolean = True
For Each item In Blked.Items
[Code]....
It is strange because this is populating the list, but adding the same process over and over again, even though I seem to have the checks in there.

Is there a way in which I can populate my listbox with an Access (.mdb) database and search for values in it. Also, can I move selected values back & forth from that listbox to another listbox (or textbox). Is this possible using Visual Studio, VB.Net?

Can you populate a Listbox and not have a default item selected?(Usually I see the first item in the list automatically selected at creation).
