I'm trying to display record information in labels, I've
got a listview filled with records and when you click on
one of them I want that record's information shown in
several labels. This is how I'm trying to do it:
private void listView_MouseD own(object sender,
System.Windows. Forms.MouseEven tArgs e)
{
// gets currently selected record
li = listView.GetIte mAt(e.X,e.Y);
}
private void listView_Select edIndexChanged( object sender,
System.EventArg s e)
{
if( li != null )
lblNum.Text = li.SubItems[0].Text;
}
With this code li is always null! li is getting set
because my other functions have been using it fine, it
seems that when it tries to access it at this point it's
always null no matter what. I've also tried putting the
line 'lblNum.Text = li.SubItems[0].Text;' right below 'li
= listView.GetIte mAt(e.X,e.Y);' but it never updates the
label. Any suggestions?
Thanks,

Do away with your mouse down handler. Access the listviewitems like this:
private void listView1_Click (object sender, System.EventArg s e)
{
Console.WriteLi ne("Item Text: " + listView1.Selec tedItems[0].Text);
Console.WriteLi ne("SubItem 1: " +
listView1.Selec tedItems[0].SubItems[1].Text);
}

Hi,
I've got a number of objects that each have it's own thread. When the value
changes I raise an event. Now, I want to handle the event in a form and show
the value in a listview.
With my first approach I had to have a synclock on the listview the whole
event handler, after some reading I've understood that updating a control
from different threads should use the controls Invoke statement.
Should I use it as well? It's not the...

I have a bunch of labels, and want to put in some container, which should be:
1. The number of labels for each column is fixed, say 16/row. And the number
of currently displaying rows is fixed, say 10.
2. The number of total rows is unknown before hand. So if it is larger than
10, the vertical scroll bar should be shown up and let the user view other
part of the rows.
3. In my program, I would add those labels one by one, from left to...
