You need to handle the IHTMLDocument2.body 's onmouseover event in order to get the current element under the mouse. Copy the code snippet and see how it works in the browser. Everything JScript can do your application can do because they use the same automation server - the WebBrowser control or MSHTML (which is hosted by the WebBrowser control):
<html>
<head>
<title>Test</title>
</head>
<body onmouseover="showCurrentElement(event)">
<p>This is a paragraph of text with a <a href="http://www.microsoft.com">hyperlink</a> embedded.</p>
<p><b>Look at me - I'm bold!</b></p>
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
<p id="currentElement"></p>
</body>
<script type="text/jscript">
function showCurrentElement(e)
{
var lbl = document.getElementById("currentElement");
if (lbl)
{
lbl.innerText = e.srcElement.tagName;
}
}
</script>
</html> You really need to read the links I gave you regarding COM interop. There's also several articles on this site about programming with the WebBrowser control, as well as on MSDN[^]. There's a lot to understand, but it's not difficult especially if you understand COM.

you mean that i should add this code snippet in my C# program?
|

No, you should do something like the HTML - which is what I said in my previous post - and handle the IHTMLDocument2.body.onmouseover event like you would any other event. You get the srcElement (the element that fired the event) from the IHTMLEventObj .
The HTML was - again - an example of what you need to do. I've given you plenty of samples and you can find more by clicking "Search comments" to search this message board (and others, if you like) or use the search box at the top of every page to search for articles.
If you read the documentation I've linked for you all this will make a lot more sense.

Ok here goes, if i can get a program to compile and work in the windows version of mono...then is it possible for the program to run in linux and windows...if not will the code compile ok in linux then.
|

If you can get it compile under Mono using the Mono C# compiler, in theory and mostly in practice, your application will then run on both Windows and Linux. I say in theory only because, as is the case with Java, there are some caveats; certain features may work slightly differently on some different platforms.

Mono is another implementation of the Common Language Infrastructure (CLI), of which .NET is Microsoft's implementation. The CLI states that certain things must be implemented and Windows Forms, for example, is not one of them. So long as you classes defined in ECMA-certified base class libraries (like those assemblies of the .NET BCL having the publicKeyToken value b77a5c561934e089) it should work.
Mono and .NET have different ways of implementing Windows Forms, however. The .NET BCLs P/Invoke native Windows APIs and handle messages since they encapsulate the Windows Common Controls. Certain implementations of Mono use the QT or GTK toolkits. This is where things really different.
Also keep in mind that .NET compilers (that is, language compilers for the .NET Framework) wrap IL modules in a PE/COFF executable but Mono can handle this.

Hi all,
How to communicate between an application and a windows service on the same machine.
Here I want to access data generated by service and process it through an application(UI) and then, send some data from the application to the service to add it in the log.
Thanks..

The best way is whatever inter-process communication (IPC) protocol works best for you. If both executables are managed, then I recommend .NET Remoting[^]. The remoting infrastructure loosly defines the transport and formatting layers for IPC and is built on and for managed code. It isn't a straight-forward infrastructure, however, so I do recommend picking up a book on it depending on what you need to do (the move advanced objects you require to communicate, the more you should invest a an inexpensive book).
You could also P/Invoke RPC functions, but to do so would require you building an infrastructure similar to .NET Remoting.
With .NET Remoting you should use a TcpChannel in this case (lower overhead; .NET 2.0 will introduce named pipes for a channel for faster transport) but you could always use a TcpClient and TcpListener with your own protocol for marshaling (serializing and transporting) objects.
The sky is the limit on this one.

I have created several layers of dialog boxes using MFC C++ .Net. However, I do not want to automatically go back to calling dialog when I hit return anywhere in the active dialog. I want to just be able to click on OK button to do this.
I have the OK button as not the Default button, but clicking anywhere in Dialog box always closes the active Dialog Box and goes back to calling Dialog box. Is there a fix?

Will very much appreciate if someone pointed me to a Wintab32 library class in c sharp
|
|
|
|
|

In VB6, you can do the following:
foreach control in form
//do stuff to each
next
In c#, you have to add an identifier to use the foreach with the array or collection.
I want to loop through a group of controls (like radiobuttons, etc.)
i.e. foreach (RadioButton in form1) {//do code}
Obviously, this code will not work, but does anyone know how this can be done in C# ? I would appreciate the help.
Thanks in advance.

Just declare a variable for RadioButton inside foreach like this
foreach(RadioButton radioButton in form1) {//do code}
|
|
|
|
|
This will only work if there are only RadioButtons on the form.
I would try the following:
foreach (Control control in form1) {
RadioButton rb = control as RadioButton;
if (rb != null) {
}
}
|
|
|
|
|
That option will work (going through each control, then doing an if-statement. Another option would be to write your own iterator that returns an IEnumerable list of radio buttons.

OK... I admit to being a newbi (one that WANTS to learn), but something is not working.
I cannot use the foreach because of the following:
" foreach statement cannot operate on variables of type 'System.Windows.Forms.GroupBox' because 'System.Windows.Forms.GroupBox' does not contain a definition for 'GetEnumerator', or it is inaccessible
I tried it in a usercontrol as well with the same error.
Do I need to make the groupbox IEnumerable? I am not sure about "write your own iterator that returns an IEnumerable list of radio buttons". Sounds like fun... Could you let me know what is involved?
THanks

Oh... I made a mistake. Change the foreach line:
<br />
foreach (Control control in form1.Controls)<br />
The Controls property gives you a collection class over which you can iterate. You can do the same thing with any container control.

I was just wondering if someone could nudge me in the right direction on this one. I am just trying to figure out how i can grab formatting information on individual characters in a richtextbox.
Example:
if i had this in the rich text box:
"Mary had a little lamb"
I would want to be anble to know that M is bold, as are a r and y, and so on. Any ideas?
Yes, I am the highly suggestable type.

Look into the the RTF property of the RichTextBox. There you will find the text including all formatting. If I remember correct bolded text is enclosed with '\b' and '\b0' or something similar. You will have to search for the specifications (Google is your friend ) or just try it out.
