Yes, that's much easier. :thumbsup: Luc Pattyn [Forum Guidelines] [Why QA sucks] [My Articles] I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

"Scrolling Around with the RichTextBox Control" discusses how to do that in VB, and there is a C# translation in a message at the bottom of the article. [Forum Guidelines]

Thanks for the very helpful reply! It confirms that I'm not crazy--maybe--and it gets me past that wall. Tom

That solved the problem. Thanks! Tom

In your current set up, that is the correct way IMO. Dave BTW, in software, hope and pray is not a viable strategy. (Luc Pattyn) Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia) Why are you using VB6? Do you hate yourself? (Christian Graus)

I swear I searched all over... (i.e., I'm embarrassed!) The sure was a good start! Thanks, Henry. Tom

Hmmm... I'm very surprised/disappointed. Thanks, Tom

I just needed a push in the right direction--and you gave it to me--thanks, led mike. I found a helpful web site: http://www.codeproject.com/KB/architecture/components.aspx[^] Thanks again, Tom

I found a great explanation at http://www.bobpowell.net/toolboxbitmap.htm[^] Thanks to all.

Perfect! Thanks. Can I store a data file icon in the executable? If so, how can I associate this icon with the (corresponding) data file? modified on Friday, February 29, 2008 5:27 PM

I should have been able to figure that out! Thanks! Tom

Wow... thanks, Patrick. Hmm, this is not the behaviour one would expect, but who says life should be predictable :sigh:. My workaround was: ----------------------------- using System.Drawing; using System.Drawing.Drawing2D; using System.Windows.Forms; namespace RegionTest { public partial class Form1 : Form { RegionData[] regionData = new RegionData[2]; int currRegionIndex = 0; MyControl myControl = new MyControl(); public Form1() { InitializeComponent(); GraphicsPath gp0 = new GraphicsPath(); gp0.AddEllipse(myControl.ClientRectangle); regionData[0] = (new Region(gp0)).GetRegionData(); GraphicsPath gp1 = new GraphicsPath(); gp1.AddRectangle(myControl.ClientRectangle); regionData[1] = (new Region(gp1)).GetRegionData(); myControl.Region = new Region(region[0]); Controls.Add(myControl); } private void button1_Click(object sender, EventArgs e) { currRegionIndex = (currRegionIndex + 1) % 2; myControl.Region = new Region(regionData[currRegionIndex]); myControl.Refresh(); } } } ----------------------------- which in the end is similar to yours in efficiency (I guess) but yours is more elegant. Tom

Hmm... possibly so, but how do I get at it? Again, what I want to do is host controls (actually buttons) on the dropdown area. In other words, I don't want to display the normal ToString() manifestation of objects in the Items collection. Thanks, Tom
