VB6 To Listview FindItemWithText Zero Error?
Jun 18, 2012
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 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 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.

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.

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'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?

I have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?

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?
