am developing a point of sale program for a project subject. The trouble im having is when i press on the button to add the item from a textbox to a listview i receive an error: See attached Screenshot.
my code is:
Private Sub SalesScreen_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.CustomerTextBox.Text = "Cash Customer"

I have a ListView on one form that i am wanting to read the items and display on a different form. My code:
Dim oList As ListViewItem
For Each oList In fSOOrderEntry.OrderList.Items
lstDetail.Items.Add(oList)
[Code]....
I don't know what this means. i want to ADD each listviewitem from one listview into another listview.
I currently have a line of text in my listview that is too long for the current width of my
listview, without increasing the width of my listview, is there a way to add a newline within the
listview line item so that it's 2 or 3 lines long so there's no need to have the user scroll to see
the text?
when I create a listview item programmatically and add listitems I get error "The object variable or with block-variable is not set".This occurs only when the listitems are added on another place then where the listview is created.

I have a VB.NET WinForms application. While adding a new data source, it is giving "An item with the same already been added" on the Add Data Source wizard form.
The application does not contains any existing data source.
What could possibly be causing this error, and how might I go about resolving it?
Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

removing Listbox item from checked Listview item.The code I tried just errors out.
Private Sub ListView1_ItemCheck(sender As Object, e As System.Windows.Forms.ItemCheckEventArgs) Handles ListView1.ItemCheck
If (e.CurrentValue = CheckState.Unchecked) Then
ListBox1.Items.Add(Me.ListView1.Items(e.Index).Text)
ElseIf (e.CurrentValue = CheckState.Checked) Then

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

Do I really have to go through all this just to find out what item has been selected in a ListView?

Isn't there something fundamental like this? Is absolutely everything in VB.NET buried beneath a colossal heap of bureaucracy?

I'm trying to make a program that adds a menu item when right clicking files.I got a C# code here:[URL] and converted it to VB.
It's working perfectly but the trouble is, it adds a menu item to folders and not files.
These are the registry entries i added:
Private Const MenuName As String = "FoldershellNewMenuOption"
Private Const Command As String = "FoldershellNewMenuOptioncommand"
convert them so it adds the menu item to a file?
I am using ASP.NET with VB.NET as background code. I have 8 ImageMaps in my webform Estimator.aspx.Each ImageMap represents a car part (Front Bumper, Rear Bumper, Mirror, Hood, Sunroof, DoorShell, Headlights, Tail lights) and I have a dropdownlist ddlChosenParts. When the user clicks on any of the 8 ImageMaps, I add the PostBackValue to the dropdownlist ddlChosenParts.The problem is that if the user clicks on the same ImageMap twice, the PostBackValue is added twice.I want to check if ddlChosenParts contains the ImageMap's PostBackValue and if it already contains it, do not add it again. That means that if the user clicks more than once on the same ImageMap, it's PostBackValue is only added once in ddlChosenParts.I have this code but i'm getting an error: Value of Type String cannot be converted to ListItem.

View 4 RepliesI've currently picked up a small project and they one who assigned me to it wants me to upgrade the app using .NET.Is there any way I could add an item to a listview when I'm not on the form containing it? In VB6, something like this would work.
'Code on Form2
Form1.ListView.ListItems.Add "Item Name"
but in VB .NET, the code below doesn't add anything to the listview. It doesn't return any errors too.
Form1.ListView.Items.Add "Item Name"
And another thing, why is it that when I close the Login form to launch the Main form, the Main form closes automatically? The code in sub main is
' shared sub main
Application.Run(New frmLogin())
Then when correct credentials are given to the form, I'll do this.
'login form
Dim frmMain as frmMain = new frmMain
frmMain.Show()
Me.Close()
I assume things are done a lot differently than VB6.
I have a ListView with two columns, first column contains a list of urls and I want the second column to display the google pr for each url. I already have the code to get the pr but I am not sure how to add that value to the ListView sub item(second column)
Dim prCheck As New TGooglePR()
So how would I add the value from the above code to the second column for each url? I have the following but not sure how to get the value added to sub item

I have an Access database with a Parts table. I'm using tableadapters in my project. A datagridview on my form is filled manually in code. One column of the DGV contains a columntype of combobox. I've got a bindingsource on my form whose source is the Parts tableadapter. The combobox column is tied to the bindingsource and is displaying fldDescription.
The part descriptions can be changed by the users, but the original part description is saved in another table that is used to fill the grid. If part "widget" gets changed to "widget, large" I can no longer display "widget" in the combobox of the grid. I need to know how to be able to add it to the bindingsource so I can display it in the combobox. I don't want it saved to the Parts table though.
I'm new to databasing. How do you make it so you can add an item to a database on a form, Then follow a link to another form which has the database on, then what you put in on the previous form will be there?
How's it done? Sorry - Haven't been using VB very long >.<
I have made it so that as soon as the form opens it puts an icon in the tray and when you right click the icon it comes up with a contextmenustrip. in the form I have put a button and a textbox. when you click the button, it creates a new item in the contextmenustrip What I wanted to do was add a peice of code to this new item, is this possible?

View 13 RepliesI have an app that I have made. The application generates 14million combinations of numbers and inserts them into an Access Database.

View 5 Repliesi've written a database program which runs fine from the ide (vs 2008). when i install this program, all database operations do not work. i tried running it as an administrator using an admin command prompt, it worked. now for my less tech savvy clients, is it possible that when they right click the programs icon they can use the 'run as administrator' menu item? how can i achieve this. if it's too much to implement, will moving the database from the application path to, say, documents, solve this issue?

View 1 RepliesWhen adding a new item (class, control, etc) in C# it will automatically add a namespace to the file depending on the location in the project.
Is this also available for VB.NET?
The code 'Namespace DataClasses.AX' and 'End Namespace' would be generated.
Namespace DataClasses.AX
