Hi and thanks in advance for your help.

I am working through chapter 13's example on the ListView control right now. There are 2 errors I find with it (either my fault or not .. that's what I'm trying to find out).

The first error I get occurs when opening a txt file (or any file) using the event "ItemActivate" of the ListView control. With a txt file, it seems to open the file twice. I revamped the code to use the event "DoubleClick" with the same code and it works fine.
           Why does the "ItemActivate" event open the file twice.

The second error occurs (I will assume because of the "Item Activate" event) when I open a folder. This produces a "System.ArgumentOutOfRangeException". This happens with all folders at any level. Moving back a folder works fine. The line with the error is "string filename = lw.SelectedItems[0].Tag.ToString();" and it is not in a loop.

So, that is my current situation. I have gone line by line and it is identical to the text. I am stumped. Anyone with any idea what-so-ever ... please help.

I may have figured out why this is happening. But I would like a guru (or at least someone who knows more than me about C#) to verify my findings.

It would appear that if I use the design editor to add an event "ItemActivate" the subscription to that event is placed in the "#region Windows Form Designer generated code" section of the code automatically. Since I had done it this way, I should have left the event subscription out of the constructor.

In any case, once I removed one or the other of the subscriptions, the code works perfectly.

Can someone validate this for me? Am I wrong in my hypothesis and conclusion?

Hi Yor solution may correct !
But I am not using DesigerGenerated Code but I do write EventHandler Syntax manually (in vb like AddHandler ItemActivated , Addressof .... so on)
but Same thing happens with me , means ActivateEvent Executed twice ??
Why ?
