Yup I did set that property to "true".
I'm thinking that maybe a command like "get-process" actually finishes before I can even click the "Abort" button, and that the delay in execution time might be from generating the output. You think that's possible?

Yes - very possibly. You could use break points and/or some Console.Write("xxx has completed") to figure out what's happening. Better still, once your get-process has completed set the Abort button to Enabled = false;

In your worker method you need to check the CancellationPending[^] property and abort the process if it's set to true.

Is there an event that raise if the collection of ListViewItems in the ListView has been changed?

Looking at the documentation it appears that you do not have such an event. But since the ListView can take a list of objects, you can have your objects either expose an event or a IsDirty property to indicate if values have changed within them.

Do you mean the collection being changed (i.e. an item added) or an item in the collection?
If the first then not specifically for an Item(s) being added. The Invalidated event is raised but it's raised for other things too so may not be useful.
You could create your own class that inherits from ListView.ListViewItemCollection and override the Add method and raise your own event in there, or simply create your own event elsewhere and raise it every time you call the Add or AddRange methods.
You may need to do the same for the remove methods and clear methods as well.

I also tried to inherit an own class from ListViewItemCollection and raise a Changed event if any item were added or removed, but i don't know how to set the inherited class to the ListView.Items collection.
Therefore i inherit an own ListView2 from the ListView class and tried to set the Items:
base.Items = new ListViewItemCollection2();
But base.Items is readonly...

Hi ho
I'm new to this forum, and I hope I'll be using it alot in the future.  Now my question isn't a technical one about programming, but more about the structure of a menu. You know these very familiar menus where you got File, Edit, View, ... I've got a question about the first one: File. Almost all applications I see use this one, but sometimes it seems to be losing its use even in the widest meaning of the word 'file'.
For example, Windows Live Messenger (or MSN Messenger in the past), uses File. When you open it you get actions like logout, or change your status. Even if you think of file as the file of contacts in your messenger, the actions are not corresponding.
Another example, Privoxy. It has nothing to do with manipulating files or whatever, it's used as a proxy program. Still it has the dropdown menu File, with only one action: Exit.
File seems to be used as a general keyword where you put all the general actions for your application, like quitting it.
So am I right if the menu word 'File' is actually being abused in a way? And is there another better keyword to be used for programs that have nothing to do with file manipulation?
Thanks in advance

It's a standard that people are used to, so they know where to go for general operations even if they're not actually file related.
I often change this for the name of the application and people rarely notice - they just seem to go for the first menu, but this is non-standard.

Hi,
for a long time there have been guidelines in place about GUI design; both Apple and
Microsoft early on suggested to always have File, Edit, View menus to the left, and Help
to the right.
The File menu is supposed to hold actions pertaining to the whole document (hence New,
Open, Save, ...) and the whole app (Preferences, Quit, ...). The Edit menu normally
holds actions on the document control, the View menu controls how things are shown.
There are guidelines/conventions for the shortcuts too (such as CTRL/C = copy).
I'm all in favor of these GUI guidelines, since they tend to reduce the discomfort
for novice users, and increase the efficiency for all users.
However there are applications (such as games) where the menu names don't really fit
the app domain; then it's up to you to cope with that.

I'll just choose something else then. I think it's enough to be the first dropdown menu for people to know that's the general tab. I'll take something like 'Program' or so.

Jitse,
If you're interested in this kinda thing, maybe have a read up on HCI.

I am writing a simple console app using C#. I have everything working peachy but when I call a method on an assembly I am using, it writes a warning message to the console window. The message is mostly useless for my purposes. I don't want the users of my program to have to parse the output because this message occasionally appears. Is there a simple way of intercepting this message to prevent it from making it to the console?
Example
This is what is being written to the console:
RPC Extension not populated!
X: 57 Y: 122
This is what it should be:
X: 57 Y: 122
|

You can intercept the standard output stream; have a look at Process.StartInfo.RedirectStandardOutput.

System.Console.Out is a reference to a TextWriter
System.IO.TextWriter tw = System.Console.Out ;
System.IO.StringWriter sw = new System.IO.StringWriter() ;
System.Console.SetOut ( sw ) ;
System.Console.SetOut ( tw ) ;
sw.Close() ;
System.Console.WriteLine ( sw.ToString() ) ;
