I've been tearing my hair out (and I can ill afford that!)
for hours trying to associate an icon in the toolbox for
a user control that I created. Whatever I do, the icon is
always the stock icon (the gear).
I created a 16x16 bitmap, and made it an embedded resource
in my control. I gave the control class an attribute as follows:
[ToolboxBitmap(typeof(CommentBox), "CommentBox.bmp")]
public class CommentBox : UserControl
I have a test form class, that when I bring it up in design mode,
I would like the control to show up in the toolbox (with its
correct icon). I have tried the "Choose item..." context menu item in the
toolbox to remove the control dll, and then reinsert it...to no avail.
Any suggestions what I'm missing?
Thanks,
Tom

what version of Visual Studio are you using? It's possible that you have to create a custom control to associate a custom icon with it.

VS 2008, Mike.
Actually, I just want an icon for the tool box.

That's what I'm talking about. I seem to remember in VS2005 (which I am still using) that you can't associate a custom Icon to a User Control. You may need to do a Custom Control if you want that feature.

Other than having a
protected override void OnPaint(PaintEventArgs pe)
method, what makes a custom control "custom"?
I tried inheriting my control from System.Forms.Control,
rather than UserControl.
Still no luck.

It's not that it's "custom" it's that it is not a UserControl. It implements one of more interfaces that provide various integration capacity with Visual Studio.

here is what I have in VS2005 that works for an extenderProvider
[ProvideProperty("ShowMRUList", typeof(ToolStripMenuItem)),
ToolboxItem(true), ToolboxBitmap( typeof(ToolStrip))]
public partial class MRUMenuItem : Component, IExtenderProvider, IDisposable, ISupportInitialize

Say you have a structure like this:
Root
\__ Bin
\__ Controls
\__ Commentbox.cs
\__ CommentBox.bmp
You could use the attribute as is above.
If however it exists in a another folder, you would have to refer to a type in that folder that has the same namespace of the folder.
Example if the BMP was in the Resources folder:
[ToolboxBitmap(typeof(Resources.ResourceManager), "CommentBox.bmp")]

Hi,

}
Please help.

I think you will get help better if you posted this question to the ASP.NET forum

You are getting a general communication error, so it could be any number of things. Go through the basic diagnostics first: can you ping the web service server from where your code is running? Try also to load the web service URL in your browser, if it's http based.

Are you certain that the web service is running? Do you have the proper URL and permissions to access the WS? Try updating your web reference... does it work? If not, you either have an incorrect URL or the WS is down. If it does, then make sure the new Web Reference exports such a call. Let me know if you figure it out (or if both the WS responds to the update AND that method is exported).
Sounds like somebody's got a case of the Mondays

My web service is down too, can you ask them to bring it up while you are at it?

Hello,
I am having problems with a tree control in a windows form application. Sometime yesterday a typecast that I was using wuit functioning and I can't figure out where the problem started. I have a class that is an extents the System.Windows.Forms.TreeNode class. It adds fine to the TreeControl, but when I go back and try to read the object and cast it as the new class it throws the following exception. What could have happened to make this start failing? I am including the adding and the locating a node. The adding program sometimes throws a duplicate value, which is tested by the FindChildNode before adding it. The FindChildNode is the biggest problem right now and is throwing the following Exception (Bolded line is throwing the error).
Message="Unable to cast object of type 'System.Windows.Forms.TreeNode' to type 'InternalApp.ECDTreeNode'."
<br />
public class ECDTreeNode : System.Windows.Forms.TreeNode<br />
{<br />
.<br />
.<br />
.<br />
public ECDTreeNode FindChildNode(string cText)<br />
{<br />
ECDTreeNode ret = null;<br />
for (int i = 0; i < Nodes.Count; i++)<br />
{<br />
ECDTreeNode tn = (ECDTreeNode)Nodes[i];<br />
if (cText.Trim().ToLower().CompareTo(tn.Text.Trim().ToLower()) == 0)<br />
{<br />
ret = tn;<br />
break;<br />
}<br />
}<br />
return ret;<br />
}<br />
}<br />
public void AddSorted(ECDTreeNode tn)<br />
{<br />
bool bFound = false;<br />
try<br />
{<br />
for (int i = 0; i < Nodes.Count; i++)<br />
{<br />
if (tn.Text.CompareTo(Nodes[i].Text) < 0)<br />
{<br />
Nodes.Insert(i, tn.Text.Trim());<br />
bFound = true;<br />
break;<br />
}<br />
}<br />
if (!bFound)<br />
Nodes.Add(tn);<br />
}<br />
catch (Exception e) <br />
{<br />
MessageBox.Show(e.Message, "Exception Error", <br />
MessageBoxButtons.Ok, MessageBoxIcon.Error);<br />
}<br />
}<br />
<br />
}<br />
<br />

Leo Smith,
What is the collection "Nodes" ?, Is it a collection of System.Windows.Forms.TreeNode or ECDTreeNode?
Regards,
Gareth.

Nodes is a collection ECDTreeNodes.

My bet is that you are unintentionally adding a node somewhere using a string to the collection, instead of sending your pre-created node. Put a breakpoint in on the problem line to see what type the node is, and I bet it is just a TreeNode. Once you see which node is causing the problem, try to trace back to when it was created, and I bet you have a line like "tree.Nodes.Add("Some string")" instead of creating your own ECDTreeNode object, then adding that object. Good luck,
Sounds like somebody's got a case of the Mondays

Leo Smith,
If this was true, why do you need to cast it?, since Nodes[i] would return a ECDTreeNode. Think it might be a good idea to:
Trace.WriteLine("node == " + Nodes[i].ToString());
Regards,
Gareth.

I think that Leo was saying that the objects are EXPECTED by him to be of his type... I don't think that the collection is actually strongly typed to his objects, though, which is what is leading to the error (I think). I also don't think that type casting an object to it's own type throws an exception, but I can't say that I have ever tried it to find out. Any comments on this, Leo? Is the collection strongly typed to your object, as understood by Gareth, or is it just a TreeNode collection, as interpreted by me?
Sounds like somebody's got a case of the Mondays

Thanks both of you. The trace assisted in finding out that the was no error, since as Jeff suspected, I had added a string (although technically I inserted a string value and not a ECDTreeNode). I was unable to find this error only because I almost never insert a value. I had looked at all my Nodes.Add() calls before I posted. The trace let me know the type was wrong and Jeff's "you are probably adding a string" instead of a ECDTreeNode made me stop and look for something out of the ordinary.
Thanks,

First: Don't shout. It is rude.

What does that mean? A project title tells us very little.
If you want help then you are going to have to tell us more about your project and prove that you have at least made an attempt. We will not help you get a qualification if you are not entitled to it. In other words YOU MUST DO THE WORK!!!

Sounds to me like he doesn't really want help, just someone to give him a .sln with everything he wants, not going to happen. Have a feeling a few more of these are going to pop up on these forums (dissertation/final year project deadline time) this time of year.
