I am trying to solve an issue in my application where the following exception is occurring: there is already an open datareader associated with this command which must be closed first. I am using TableAdapters, which maintain their own DataReaders, and everything seems to work fine unless I am interacting with one of my background workers.
In my code, I shadow the Item property of my collections so that I can retrieve the actual data from the database if needed. Here is a sample:
[code]...
Now each reference to the Item get property instantiates its own DataAdapter, so I am confused as to how the same DataReader will ever be used in this scenario. Is there something I am missing? All the TableAdapters do in fact use the same connection object, but I wouldn't think that would be a problem

I have a string which gets data from mssql server, reader collects data (among others also "person) SQLStr = "select * from tablename order by id desc command = New System.Data.SqlClient.SqlCommand(SQLStr, connection) reader = command.ExecuteReader() While reader.Read() ListView1SelectedItem = reader.Item("PERSON") List view contains list of persons (with IDs), including "person" from the reader. What I want is that item from reader.Item("PERSON") is selected/highlighted in the listview.

List view contains list of persons (with IDs), including "person" from the reader. What I want is that item from reader.Item("PERSON") is selected/highlighted in the listview.
I've started from this: ListView1.Items(0).Selected = True ListView1.Select() ListView1.EnsureVisible(0) But it always select first item in list view and not the actual reader.item.

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
I am using the following code to load an ArrayList with an object. [code]I don't know how to retrieve the object from the ArrayList using the Item property. I am using the following withOUT Success. The code is searching the arraylist for a match on serial number. Values(2) is correct and is working fine - the problem is purely getting the object information from the arraylist.[code]How do I pull the propertys back from the object in the arraylist to compare the values with Values(2)?
However I need to interact with a program designed in vb from perl (yes I MUST do it this way....)
The control I need to get text from has a class TL80.C1List32.20 I believe this is a listview. I can get a handle to the control just fine.
I have access to the SendMessage function via a wrapper with this prototype: SendMessage( $hwnd, $msg, $wParam, $lParam ); (A $ denotes a variable in perl)
The listview also has 2 child windows of class: TL80.C1List32.20_SC which I believe are scrollbars.
I need to retrieve (but not set) the items in this listview via the wrapped SendMessage function.
I can provide any other information you'd like from Winspy++ or can probably dig it up on my own if you let me know what you need.
Using VB 2010 Express, I will try to explain what I want to achieve:1. The user installs my program.2. In an Explorer window (Vista/Win7) the user will right click any file.3. The program checks if there is an item called "MyApp" in the context menu (i.e. the menu with for instance the "Open with..." item). If not, then create the "MyApp" item which launches "TheRealApp.exe" that the user installed. Place the item after the "Print" item.
whats the quickest and least application hogging way to retrieve image from web and show in picturebox on listview selection event?
Heres the code i have already which produces app lag for abut 3-5 seconds per image loaded, i think as it stretches the image to fit into picturebox (which is needed)
vb Private Sub bwGetScreen_RunWorkerCompleted(ByVal sender As System.Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles bwGetScreen.RunWorkerCompleted

I'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
HTML For Each item In ListView1.Items i += 1 Dim prCheck As New TGooglePR()
I have a listview that is populated by file name from a folder on my hard drive. I want to add an image to the listview item, different image for each item. Here is my code:
For Each myItem As FileInfo In strFiles ListView1.Items.Add(Path.GetFileNameWithoutExtension(myItem.ToString)) Next
[Code]...
When run the file name appear in the listview but the images don't.
My overall goal is to add fake/unbound items to a listview control (for final HTML Table output reasons). This is a code behind solution. Users will not be adding items as it will be outputted in a rigid table.
I have looked at several examples and while this is easy for a dropdown it is not for listview.
The code below works without error, but my item is not shown on runtime. I think the class is not setting the item fieldname correctly, but I can't figure out the right syntax to fix it.
ColumnNameAList.DataSource = PeriodDataView ColumnNameAList.DataBind() Dim test As New Example1("ColumnNameA")
Below is the code that will and does add to listview1 when triggered, but, will not remove it. I have spent a lot of time trying to figure this one out. There is not any error even when I step through.[code]...
I have a list view control on one of my forms in my program.If i click on a selected item and click on the delete button it gets removed. But i want it so that if i havent got an item selected i click on delete i get a message box telling the user to select an item to delete.
