Strangely, the code originally posted[1] had BeginUpdate/EndUpdate (it
was the first thing I looked for in the code).
[1]
listImports is a ListView
Hostnames is a Hashtable
HostnameListViewItem is a ListViewItem
listImports.BeginUpdate();
foreach(string hostname in hostnameController.Hostnames.Key

Good point. Begin/EndUpdate are helpful, but I've just had better
luck with AddRan

We agree on the numbers being almost completely meaningless.

I hate to be argumentative about this :)
Numbers really are almost completely meaningless to me on this issue.
Forget the numbers. Pu
Not using an ArrayList (and using a ListViewItem array) is faster; but it's
still slower than individual calls to Add, by less than 11%.
I know, it goes against logic. Maybe .NET 2.0 will be better.

GetCustomAttribute*s* (note the plural form) returns an array, hence
the indexer [0]. The AssemblyDescriptionAttribute class is attributed
itself with [AttributeUsage(AttributeTargets.Assembly,
AllowMultiple=false)], which means that you can use it once per
assembly, hence again the index 0 used by
Hey All,
I have a MDI application, having some remoting tech.
When a lauching thread (not UI thread) goes to display a dialog box, the focus
is lost. But if it runs inside MDE , the focus is right.
So anyone knows how to regain the focus easily?
Thanks in advance

I've actually found that the following is *faster* than AddRange:
listView.BeginUpdate();
for(int i = 1; i < 65300; ++i)
listView.Items.Add(i.ToString());
listView.EndUpdate();
where the AddRange snippet is as follows:
listView.BeginUpdate();
ArrayList list = new ArrayList();
for(i
This works great, thanks! The "[0]" implies there might be more than one.
So if there were two or more, they might be referenced by
GetCustomAttributes(typeof(AssemblyDescriptionAttribute), true)[1];
for example. If this is the case, what would be the syntax of the source
assembly info?

Your point about reconsidering design is a good one. However,

In addition to the AddRange sugeestions (which, by my profiling only

list view gives you in this case is the ability to "search" for entries

Thanks Steve. Here's what I ended up with[1]. Saves me from having to
convert the ArrayList. Works SO much faster!

ListViewItem[] items = new listViewItem[hostnameController.Hostnames.Count];
int i = 0;
foreach(string hostname in hostnameController.Hostnames.Keys)
{
items[i++] = new Hostn
Have you tried AddRange instead of Add? It seems to be faster from what
I've done in the past.

Yes. Create your items and add them to an ArrayList. Then convert
the ArrayList to ListViewItem[] add the array using the AddRange
method.

This bit of code[1] runs very slow because I have to add 65000+
ListViewItems to the ListView. Is there any way to speed this up?

Note that the documentation is often misleading - there are plenty of classes
in the framework that claim to be using threads or the thread pool when they're
actually doing intrinsically asynchronous calls as Mike describes.
