Come to think of it, since you where reading two lines per iteration, you only showed six,
and you might (did) try and read a line after you tested for null. That must be why the stream objected.
BTW: the code you showed originally was incorrect in a different way, and would not have compiled.
I guess you are better of showing actual code right from the start.

Yes, I just didn't have the original code at hand. BTW, why wouldn't it compile? The only reason I can see is that it's incomplete, but I just posted an excerpt.
This one was a nasty. The original code was getting an FTP 550 error, file not found or no access, because the directory I was trying to create already existed. It made no check of this, and almost ignored the FTP error by only catching and logging the exception. Because I was breaking when thrown, I noticed an exception that is actually often expected, but I suspected my changes, adding authorization, had introduced the problem. Because another developer had broken the function I needed to execute the code, I extracted it into a separate project to experiment, beginning my troubles.
[Edit]
Ah, I see in the original code that I was trying to write the StreamReader, not the filename, which results in System.IO.StreamReader appearing in the console, just before the same disposed object exception.

Which is a pity. The original post didn't show a double ReadLine (the extra one without null-test);
if it had, I guess some one would have noticed earlier.
Anyway, the detour with the Microsoft server allowed me to run your code and compare results.
Glad I could be of help.

Just curious. How do you handle editing? Superimpose a TextBox on the edited line?

I changed my sig to the textbox/picturebox stuff since too many people get into trouble,
they either start drawing on top of a picturebox and complain an image.save doesn't capture the drawing,
or they have trace/log output in a (rich)textbox and they don't get it to work properly and/or it starts to slow down dramatically as the number of lines increases.
Most of my listboxes are for output only; I have done some editing though, just handling all the key/mouse stuff myself. I don't like (rich)textboxes, they don't scale well. I basically did my own editor based on a Panel; I can teach it every trick I want without constantly fighting RTF troubles.

Have done that too (single-line textbox on top of label), it works rather well. Solves some of the read-only problems.

I am kind of asking a general question here. When you use the focus function in winforms, it takes the cursor away. What I mean is id I have a control called uxTxtbox and another one called uxBtnSubmit and I go with uxBtnSubmit.focus();, it will then remover my cursor from the textbox and highlight the button but the user needs to type something in. That is I could call the text changed event of the text box but that of course would mean each time the user typed something in, he would have to click the text box again to add another character. Now I know I could easily just call a keypress event of enter and do a uxBtnSubmit.PerformClick() but I kind of think that would just be avoiding the whole thing. Plus, a smart user will see that the submit button isn't highlighted and will think that they have to click the button or tab over to it. Is there a way that the button can be highlighted the while user is typing?

The button being highlighted means that it has focus. The textbox being highlighted means that the textbox has focus.
If the button is 'highlighted' (if it has the focus) then the cursor is standing on that button. (You can't see it, but if you press the spacebar, you'll interact with the control that has focus - the button).
Only one control can have the input-focus at a time.

I knew there was a solution. You are not supposed to mess around with the focus for the submit button. If you set the acceptbutton property of the form to the button you want, then it will always be highlighted and when you press enter it will be pressed.

Hi there! I need some help with events for dynamicly created objects. The code below illustrates the problem. My situation will be a little different since the objects I will be dynamicly creating will be custom, but the problem is the same.
The event will only fire on the last created object. How can I have an event fired within the form Class each time an individual instance of the label is clicked??
Public Class Form1
Friend WithEvents lbl As Label
Private i As Integer
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
i = 1
End Sub
Private Sub Form1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseUp
lbl = New Label
lbl.Name = "lbl" & i
lbl.Text = "Label " & i
lbl.Location = e.Location
lbl.AutoSize = True
Me.Controls.Add(lbl)
i += 1
End Sub
Private Sub lbl_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbl.Click
MsgBox(lbl.Text)
End Sub
End Class

This code won't work. You only have one label wired up with it. Basically, you can't use WithEvents on a class-level variable and expect this to work. Drop the "Friend WithEvents..." line completely. Your MouseUp code has to create the label and wire up the events itself. This way, every label you create will maintain event connections.
Private Sub Form1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseUp
Dim lbl As New Label
' lbl.Name = "lbl" & i ' Drop this line. It's not necessary
lbl.Text = "Label " & i
lbl.Location = e.Location
lbl.AutoSize = True
AddHandler lbl.Click, AddressOf lbl_Click
Me.Controls.Add(lbl)
i += 1
End Sub
and drop the "Handles lbl.Click" from the end of the Sub you defined.

Hi,
my application wit database accsess is running fine on the System I developed it. When distibuting it on a other PC - without installation - I get the error message "Can't find System.EnterpriseServices.Wrapper.dll or one of it's dependencies".

You shouldn't be doing this from your code. This should be done at installation time, by the installer. I'm not even sure it would work if you tried to do it from code.
