Hello,

I am trying to add an item to a checked list box, like:

clbList.Items.add("Hello",true)

I get an error back:

Run-time exception thrown: System.ArgumentOutOfRangeException - Specified
argument was out of the range of valid values. Parameter name: '-1' is not a
valid value for index.

This doesn't make a lot of sense? Any ideas why this happens?

I am not able to repro that. Are you sure this line throws the
exception? Which version of .NET do you use?

Can't repro the prob with VB 2003. Please show me the real line of code (the
above one isn't).

I'm running VB .NET 2003 too.

I'm trying with the line quoted just to get it to add something basic.

But "add" and "true" usually start with capital letters.

Can you post the callstack from your function call down to the function
throwing the exception?

Yes, looks interesting. Tried to repro it again and to find the reason (IL
code) but I failed, sorry. Maybe Herfried will find out more.

Enclose the line in a 'Try...Catch':

\\\
Try
Me.CheckedListBox...
Catch
End Try
///

Is the exception still thrown? If yes, it's not caused by the line!

I am not able to repro it on VB.NET 2002 and VB.NET 2003. Mhm...

clbWaves.BeginUpdate()

The Catch statement is called with the Out of range exception.

Does the exception occur if you skip the 'Clear', 'BeginUpdate', and
'EndUpdate'? Are you sure you are performing the operation in the main
GUI thread?
 
I don't get an exception when I comment out the BeginUpdate, Clear and
EndUpdate.

I put back in the Clear() and its still working, so it means BeginUpdate()
or EndUpdate() or both causes this problem?

Yes, I am performing this in the main application thread.

Why would this happen?

I currently only have access to VB.NET 2002, there I am not able to
repro the "bug".
 
Hi, Simon

I can't get it to repro here either.

What happens when you start a new project, add a checked list box & a
button, and put your code in the button's click event? If that works,
there is probably something wrong in your form or project files. Have you
edited the code in the Windows Form Designer generated code section? That
could be the culpret. If the simple project fails, please zip up the
simple project and attach it to a post. That will give us something real
to play with.

Hope this helps,

Just to make sure the code is in the right place.
Can you put the code behind a command button and try it. should work fine..
 
I am trying to add an item to a checked list box, like:
clbList.Items.add("Hello",true)

I get an error back:

Run-time exception thrown: System.ArgumentOutOfRangeException - Specified
argument was out of the range of valid values. Parameter name: '-1' is not a
valid value for index.
Click to expand...

true is a boolean but its integer representation is -1.
It maybe that this suggests that the 2nd parameter was expecting an integer?
