VS 2008 Setting ListViewItem Text
Mar 31, 2010
I have a previous project that, when the user selected a specific settings, a ListView SubItem's Text was changed. There's nothing functional to this than to allow the user to see every option they've chosen.However, when I do the same on a new project, I get an error: InvalidOperation Exception: The error is: InvalidArgument=Value of '0' is not valid for 'index'..I've determine that it is the piece of code that specify's the text of the ListView SubItem. I don't know what's going on because I've duplicated everything from one app to the next.The ListView has it's columns, items, and sub items added during design time.[code]

I have a ListView, wich its View property is set to LargeIcon and there isn't any ImageList attached to it.The thing is that ListViewItem's text overlaps next ListViewItem's text. With View set to Tile I have no problem at all, but It shows the items one below another.When I add columns header,I set their width to a large number,but it seems that ListViewItem doesn't care,I get the same mentioned effect.My question is wich property do I have to change to avoid ListViewItem's text overlapping?

I am trying to include some custom events/methods when I Check a ListViewItem. I have my Class and Inherited the ListViewItem, but can not figure out how I can achieve this. I have looked at adding custom event handlers, but don't think that this is an option. [Code]. Essentially what I want is an eventhandler that fires whenever the Checkstate of the listviewitem changes.

I have a masked text box for postal codes. When the user clicks the text box it sets the cursor to where ever they clicked in the text box. Is there anyway that if the value is empty it sets the focus to the beginning.
Private Sub Cust_postalTextBox_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Cust_postalTextBox.Click
Try
[Code].....
Is the code I have that works but What would the IF statement be to check if it is empty? String.empty and "" don't work because I think it sees the mask as characters.

on cloning a selected listviewitem from listview1 when a button is clicked to listview2. How do I achieve this? Here is the code I have but does not work exactly how I want it, it just makes a clone of all the listviewitems in listview1.
foreach (ListViewItem item in this.listView1.Items)
this.listView2.Items.Add((ListViewItem)item.Clone());

I want to start a thread, which handles a class.That class should add a listviewitem into a listview on the main form.[code]No idea why that doesn't work.I really need threading, cause it would block the program.These codes are examples, the real one is with loops & stuff, so that blocks the program.

I am trying to find a way to associate a key with an index for a Listviewitem in VB.Net. I'm not even sure if it can be done with .Net but I know in VB6 I could do a
Listview.listitem.add "somestring", "somestring".
For the application I am using this in, I cannot have duplicate item.text so I would make the key the same as the string. this also made accessing the item easier since I didn't have to rely on index to update the subitems.

I have a form that has a listview with a number of items on it. In certain circumstances, when I load the form, I want a particular item to be automatically selected. The user will select the item to be selected from another form, and I will pass this item to the form in question.
But how do I tell the listview 'hey, set this item as your selected item?" There isn't a writable 'SelectedItem' property.

below is a small part of my asynchronous TCP connection code. When I connect I'm passing a ListViewItem as Object parameter. I'd like to update the ListViewItem once the connection has been established or an error occurs. ServerConnect runs on a separate thread, because it's an asynchronous connection, so I can't update the ListViewItem directly.
Does anybody know how to update the ListViewItem?
I looked at jmcilhinney's asynchronous TCP example in the Codebank forum, but it confused me. I don't know which parts I need and which parts I don't need.
::edit::
One more thing. I also need to update the ListViewItem in the Read sub, but I'm passing "buffer" as Object, so how would I update the ListViewItem there?
vb.net
Imports System.Net.Sockets
Public Class TCP
Private Socket As TcpClient

I want to modify the default Object text size for all objects I place on my form. When I am teaching, it is hard to see the text on the objects. I have changed the code area to 16 pt, but I have not seen how to modify the default font size of the object. They all are 8.8 pt.

I want to set minValue and maxValue of text boxes to define a range of acceptable values for validation purposes.In VB 6 this is straight forward and can be done under text box properties, however in visual studio vb .net 2010 this is not the case or it may be the case that i am missing something.

I've added some Labels to a form at runtime using this
vb.net
Dim x As Integer = 25
For i As Integer = 1 To word.Length
[Code]....
Now, I would like to add text to one of them, but I'm not sure how. I thought by setting .Name I would simply be able to write something like lbl4.text ="A". But, of course, because the Label has not been created yet, this is not possible.
Also, I'm not even sure if .Name is working the way I think it is. I was hoping that it would name each Label consecutively: lbl1, lbl2, lbl3, lbl4...etc.
Am I naming the Labels properly? And how would I add text to one of these Labels?

I have a listview but I would like to add 3 properties (for example one of them is "image") to the listviewitems in it. I was fine with making a custom class with the 3 properties and just inheriting ListViewItem but now I need to use MultiSelect, so it means doing things like(in For Each loops):
ListView1.SelectedItems.Item(i).Image don't work because it returns a ListViewItem not my CustomClass. I could always do : Ctype(ListView1.selectedItems(i), MyCustomClass).Image
But using that over and over again seems like a waste/wrong way to do it?

I've been tingling with the colors of listviewitems.For the most part, they work great, but I can't set alpha:
Me.BackColor = Color.FromArgb(100, 40, 40, 40)
Me.ForeColor = Color.FromArgb(1, 255, 255, 255)
Me.BackColor = Color.FromArgb(100, 40, 40, 40)
Me.ForeColor = Color.FromArgb(100, 255, 255, 255)
The result of any of these two lines is exactly the same ( no change in alpha ). The colors take ok though.

I'm having an array of ListViewItem and I want to delete the first item. I tried doing this with:
myItems(0).Remove()
But it's still there. According to the tooltip:
"Removes the item from it's associated System.Windows.Forms.ListView control"
Since my array isn't associated with a ListView control, could that be it?How to do it?
