I have a problem.
I have a Mouse-down handler for a list box.
The problem is that the list box's selected item wont change till my handler has exited.
Lets say the list box contains two items
----------
|apple |
|orange | <- selected
----------

Now if I click on apple and do a :-
MessageBox.Show(listbox.SelectedItem.ToString())

I still get orange. Next time I click I get apple.
What happens is that my handler gets called and only afterwards does the real handler gets called which changes the selected item index.

Now how do call the default handler

something like calling the base class handler

Why are you using MouseDown? Why not just use click? The problem with MouseDown is that a "click" hasnt happened until the mouse has been released, ie, MouseUp.

To illustrate, if you hold your mouse down on a list box and move the mouse up and down, the selection will change. Thus lifting the mousebutton "locks in" the item that is selected.

Having said all of that, there may in fact be a way, i havent tried :p

You could always just use a simple hit-test to find out the item under the cursor. Assuming all of the items are the same height (ie, not OwnerDrawVariable) you could use :

private void listBox1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
	int iItem = (e.Y / listBox1.ItemHeight) + listBox1.TopIndex;
	if (iItem > listBox1.Items.Count - 1)
	{
		lblCount.Text = "none";
	}
	else
	{
		lblCount.Text = listBox1.Items[iItem].ToString();
	}
}

You can lookup what the exception is and what threw it to track down the offending code.

If you don't have the documentation locally it is available online @ MSDN.

How do you implement control arrays in C#?

And why is everyone so against them!!! I mean, every time I turn around, MS is throwing them out: Can't do them in VB.Net, couldn't do it (could hack it) in MFC, etc.

What is the deal!!!

You dont need control arrays. In VB, they gave you the ability to write one event handler for a whole bunch of controls. With AddHandler in VB.NET (or using the += operator for events in C#) you can acheive the same thing, with the extra advantage that they dont even have to be the same type of controls, or the same events.

The other thing it let you do in VB was to add controls at run time. In VB.NET and C# this is now even easier.

Control arrays were an ugly way to do what .NET has made fairly elegant.

But I want to be able to use loops when I'm working with my controls...drawing them for instance...

An event isn't going to help me do that!

Thats what collections are good for Smile | :)

foreach( MyControl c in MyControlCollection )<br />
{ <br />
  // use c<br />
}

I am trying to inteface to the SENS COM object. I understand that I need to create a class that implements the GetConnectionPointContainer interface. I am unable to find the assembly or reference for which this resides in. I keep getting an error during compile time that I am missing a reference or assembly.

Any ideas? Thanks!

I have a framed webpage. On the left frame, I have search criteria in different ListBoxes, and I want to pass the selections from those ListBoxes to the right frame page, so that it can use those values to construct a select query, then show data there. How can I pass them in one aspx page (the one in left) and receive them in another( in right frame)?

Chris#

The short answer: As a query string. I guess you could hack it up to post the data as well.

Hurray!

The C# forum has 1000 posts now.

This is in fact the 1000th one. Talk about coincidence Wink | ;-)

You can find cheer in the fact that a real nice guy like me took the opportunity to post the 1000th post.
