I am trying to use some VB6 code for a listview in my .net application. However, once it converted it to vb.net code i can not seem to get pass this:
Dim ListObj As System.Windows.Forms.ListViewItem
ListObj = LV1.FindItemWithText(Name_Renamed, True, 0)
It keeps telling me
InvalidArgument=Value of '0' is not valid for 'startIndex'. Parameter
name: startIndex
I've tried to input a 1 instead of a 0 but i still get the same error message as above
I have a ListView with two columns, and before enter a new item in the listview, I want to prevent entering a duplicate value, so I found ListView.FindItemWithText to accomplish that.
But I realized that if I enter 232323, and then enter 2323, which is different but starts with the same digits as the first entry, the function returns that item as a match.
I wonder if there is any way to match the whole text (exact text) to avoid the above.
Here is my code:
Dim ChkSIM As New ListViewItem ChkSIM = lvItems.FindItemWithText("2323") If Not ChkSIM Is Nothing Then lblErrorSIM.Text = "Already in list" End If
i have a list box in the select indexchange event i have put a msgbox to print the 3rd subitem of the listview. On the first click its comming fine but on the second click it is throwing an exception ArgumentOutOfRange exception is throwing(InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index)
I have a listview that when i select the items on it, then the id would go to a lable but when i click for another item with different id it has an error here is my [code]...

Private Sub SalesScreen_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Me.CustomerTextBox.Text = "Cash Customer"
I am not sure if this is a bug, but I doubt it.I have an application that has multiple forms. There is about 5 ListView controls in the whole application (in different windows) and they all are in details view and have columns. But there is one that is not displaying right. When I am in design mode it looks fine, like this:
I have not tried it on an executable produced using Vb.Net yet though.To install: Be sure to always read the README file within the downloaded ZIP file for instructions for ALL give-aways on that website. I was able to install on VISTA 32 bit ULTIMATE edition, with no problems by double-clicking the SETUP then the ACTIVATE files directly from the WINZIP window.

I am trying to get the selected rows from a listview. To achieve this, I did this:
Dim numsel As Integer numsel = Me.ListView1.Items.Count For countme As Integer = 0 To numsel
[Code]....
It does count the selected rows, but it always throws out the error saying "ArgumentOutOfRange Exception", or something along those lines. For example, if I selected a row, it will output the results of that row. But the loop goes on. I tried everything I can but to no avail. I specifically want to select multiple rows, and I can achieve that if someone can assist me with this simple "problem" I have.
Here is the code I am playing around I am getting error populating the table cells into my listview. In my codes it is always add only in one cloumn in my lv.
Private Sub DumpTables() Dim t, c As Integer ' Used to count tables and cells. Dim IWebDocument As HTMLDocument
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.
And I select one and it works! But when I try to select a different one it comes up with an error on..If ListView2.SelectedItems.Item(0).Text = "None" Then The error..InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index
I have 3 forms, one frmMain - main form, second is frmUserType- childform, and the last frmCreateUserType. In the main form I have a menu item to open my frmUserType, In this form I have a button to open another form which is my frmCreateUserType, In this form I have a button to add records then update the listview in frmUserType. The problem is the listview will not access with my add button control in frmCreateUserType. I tried not to used mdiparent declaration for my frmMain and frmUserType as children and it works, so meaning that the problem is showing my frmUserType as childform?I am using vb.net 2008
Code to open my second form (frmUserType)
[CODE]...........
Code for my add button to update the listview in frmUserType
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 have two listview in a separate form, basically what i want to do is whenever I select a row in my first listview the items in that selected row will be copied in my second listview which is empty.
I'm using ListView control, with SmallIcons style in VB.NET. Icons are loaded fine, but when I start to scroll ListView down or up from scrollbar (clicking from arrows), rowheight drops to about half from normal in next 20-30 rows below/above upper/bottom row (depends from the scrolling position). After 1-2 seconds, ListView is "refreshed" and scrolling continues normally. When focus in on the ListView and I'm moving up/down with arrow keys or PageUp/PageDown, everything is normal. Any suggestions, what is happening? SmallIcons size is 16 * 16. Is it compulsory to set "Blank icon" with SmallIcon size to all rows, when adding them or what? Wasn't like that in VB6, how is it in VB.NET?
