I have some code which scans my Database for the table names and displays them in a listbox (ListBox1). Later on when the user selects the desired option(Table) in the listbox the code gets the text which the user has selected at loads that table into a Datatable.
DataDataTableAdapter = New OleDb.OleDbDataAdapter("SELECT * FROM " & ListBox1.Text, DataBaseConnection)
However I recieve "Syntax error in from clause"
I have been trying for days to work this code. I want to transfer the information from a listbox to a table in an access database. The listbox gets its information from a text file using stream reader. My code so far has produced an error at the NewRow Method. I am using VB.Net 2010

So I'm using the following code to add items into my list box, and I'm trying to get it to check the contents of the list box as well.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
If ListBox2.Items.Contains(TextBox3.Text) Then
MsgBox("Character already exists!")
Else
ListBox2.Items.Add(New LBnfo With {.v4 = RadioButton6.Checked,
[Code] .....
But when I try to compare the two:
If ListBox2.Items.Contains(TextBox3.Text) Then
MsgBox("Character already exists!")
Else
It doesn't show the message box even when the character actually does exist. I believe the problem is that I never do add the item really. I just use, "Return Me.character," which is assigned the value of Textbox3. So I just need to figure out how to check Me.character before returning it.

I am trying to query a MSI to get the ProductCode from the MSI so I can later populate a script with the proper ProductCode.During debugging it "looks" like the database is open for read, however if I look at the oDB object I see this "Error = No further information on this object could be discovered" When it tries to do the OpenView on the SQL statement it throws an exception "OpenView, Sql" I believe that is because the MSI really isn't open for read?I have added the reference to the Microsoft Windows Installer Object Library version 1.0.0.0
Here is the code: (I pass the fully qualified path + filename of the msi)
Private Sub GetMsiProperty(ByVal sMSIFilePath As String)
Const sReadMSIDataBaseErrorStr As String = "ERROR: Could not read MSI database!"
Const msiOpenDatabaseModeReadOnly = 0

How can I done when the user click an item to my first listbox it will open another listbox that category of the first listbox item..
I want to get items into the ListBox from Database on FormLoad.
My code is:
database
Private Sub Models_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim qry As String
[Code]....
I am already having three models in database that has to be loaded in ListBox on formload.
I am getting an error that I can't track down.
Elsewhere in the project:
Public teamname (numteams) as string.
In this form as a form load event
For i = 1 to numteams
Listbox1.items.add (teamname(I))
next i
I get an error message to try new but I can't figure out what it means.
The user enters information into a textbox, and if it is present in the litsbox an error message will be displayed, if it is not already in the listbox then it will be added to it.
I save what the user enters as a variable and i am wondering if its possible to check the exact contents of a listbox?
So suppose there is a string: StringRamdom and you display it's contents in a listbox.
so listbox.Items. Add(StringRandom) but it should be displayed as A, B, C
not
A
B
C
Is it possible to save listbox contents, on form_closing event, and reload them on the form_load event? If so, could you please show me how?

View 1 Replieshow to send all the contents of a ListBox to a MsgBox
View 7 RepliesBeen trying to figure out how to do this for a while, but I can't seem to find anything that exactly covers what I'm trying to do. I'm really a novice when it comes to vb .net, so this might be staring me in the face and I wouldn't know it.I've got a Motorola MC3090 mobile barcode scanner running Windows CE 5.0 at work. I wrote a small program (in .net 3.5) that allows me to scan barcodes and then get counts for specific barcodes when I type all or part of the barcode into an textbox. That works pretty well for receiving, but I need something that works better for the reverse process (shipping things out).
I have an textbox which accepts the barcodes. When the scanner emulates an enter key press, it adds the code to a listbox and clears the input field. This process loops as many times as my quantity field specifies. There's another textbox which I use to input partial barcodes that I want counts for. It looks for strings in the listbox that match, dumps them into a second hidden listbox, and counts those.
If you're the tl;dr type, here's the short of what I want to do with all of the above. I want to take the contents of the visible listbox, summarize by listing each unique barcode, and have a count of how many of each unique barcode appears in the listbox.
I have a listbox control (in a WinForms application) that lists a bunch of statistics about records selected from a database.
Is there an easy way using VB .NET to take the contents of this listbox and send it all to the printer, or at least have one of those standard windows print dialogs come up, prompting the user for which printer to send the listbox contents to? Doesn't have to be fancy or anything.
I am current creating a file deleter in VB.net, although for some reason I am unable to get the contents of my folder on to the listbox, my code is as follows:
Public Class Form1
Dim dir = "C:UsersLimitedDesktop"
Private Sub listbox()[code].....
I want to align a sample of data that is reproduced in the ListBox so that it would look neat. However, I have failed to find any alignment related property available for ListBoxes. Therefore, I would appreciate an expert advise on how to invoke it without extensive coding.

View 8 RepliesRecently I have browsed the web for ways to display a list of files and folders in a list box. I have successfully been able to display files in drive C and get a nurerical value telling how many files were found. However my efforts have been hampered by three distinct problems. I have some experience using batch files and when using them you can state things like "%WINDER%" to go directly to windows folder. I am wondering if there's anything like that used for navigating. And if so could an example be made of it just for clarity?
My second problem is I cant seem to be able to display files and folders. I have been limited to one or the other. That and I cant figure out how to navigate into them to display there contents. The next problem I have is simply having a user interface so you could type a file path or file extention and have the program navigate to it. Is it is possible to click a file path in a list box and chose to delete it. My second last Q how do I display all files and folders including hidden files? And How can I count all files and folders with there contents to dissplay in a listbox.
I have a listbox that acts as a running log, and I need the contents to be emailed to my boss.Currently I can only get the first item that is selected to be sent, but I want all the contents of the listbox to be in the email body.My goal is to have the whole log in the listbox send, without having to select anything.

Ive built a very small application for personal use only. Ive been working on it for around 2-3 weeks & have just finally completed it this morning.
Basically what I want to do is add a button to my form which will allow me to take the contents of the listbox and print it out or atleast be able to save it to a word document or something of that kind, I'm not entirely sure how I would go about doing this. Bare in mind, Ive only just stepped into VB around a month ago.. self learning myself via internet & several books I have at hand.
I'm trying to place the contents of a text file (just a list of names) into a list box when the form loads.
My code currently looks like this:
Imports System.IO
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code].....
I can get the names into the list box, but they're all on one line. I thought about using a For...Next loop to read the contents of the text file, but I got into all sorts of trouble; do I need an array with that method? So I've got back to the code I originally had.
