You're in a managed world for memory allocation, so it doesn't really make sense for you to worry about this so much. Just remember to instantiate an object just before it's about to be used and be sure to call Dispose() if the object is IDisposable. Let the GC do it's job and you should be fine.
But if you absolutely have to see this information, you should take a look at Son of Strike debugger. This should allow you to see your objects in memory and get their size. Again, this is not a run-time solution and I doubt you'll ever see a run-time API (at least from MS).
Here's an article on SOS debugger -> http://www.csharphelp.com/archives4/archive622.html[^]

Count the number of members in your objects and guestimate the size of them. I say guess because I believe in .NET a Int32 does not take up 32 bits but slightly more. Also, count one word for each memory reference.
Also, if you use recursion you will have to guess the call stack as that is memory usage as well.

Hi guys. I need to put a web browser into an application. I don't care what language I do it in, but I want to get events when a DOM event fires ( such as a mouseover or a click on a link ), and I want to get an event that tells me they are about to fire, which allows me to cancel the event. Is this even possible ?

Navigating will tell you when it tries to go somewhere, but I'm not sure how to capture every DOM event. Maybe if you told us what you want to prevent there is another way?

Basically, I want to be able to know when an event occurs on the DOM, so my code can do something in response, or cancel the event. There's really no other way to do it.

Here's a list of the Events for the .NET 3.5 WebBrowser Class. http://msdn2.microsoft.com/en-us/library/system.windows.forms.webbrowser_events.aspx[^]
It appears that a lot of those events that miht be useful to you are marked as infrastructure and not supported by the control, but it appears that you can just inherit from WebBrowserBase and hook into those events from there.
Sorry I can't giveyou a definite answer as I've barely used the WebBrowser Class. Good Luck.

I have to develop a web application from a web site.
On the web site, on the App_WebReferences folder, there is a folder
ContactComponent and there are 3 wsdl files, First,Second and Third inside that.
On the web site, the web service is referenced as ContactComponent.First,
ContactComponent.Second and ContactComponent.Third
On my web application also, I need to reference the same way.
How will I add all the three web services to one reference so that I can call ContactComponent.First
ContactComponent.Second
ContactComponent.Third
Thanks

graphicsPath.AddString("sample", fontfamily, ..., ..., ...);
graphic.DrawPath(pn, graphicsPath);
I have added "sample" to addstring method while application is loading. As i proceed i require to change the name from "sample" to "Item". Can i change it? If yes, how?

Even i used string variable but in vain..

I assume you are doing your drawing from either a somecontrol_Paint or OnPaint overriden method that gets drawn whenever the control gets invalidated. Therefore you can issue an control.Invalidate() and use replace the string with whatever.
off the top of my head
private void control_Paint(object sender, PaintEventArgs e)
{
string str = "sample";
if (!loading)
str = "Item";
graphicsPath.AddString(str, fontfamily, ..., ..., ...);
graphic.DrawPath(pn, graphicsPath);
graphicsPath.Dispose();
pn.Dispose();
}
then somewhere, relevent, in you code issue;
isLoading = false;
control.Invalidate();
Hope this helps,
Mike

I am writting a progam to demo CSMA/CD in the Ethernet, but I don't know how to do. Who can give me code for CSMA/CD? Thanks you very much. Help me!

If You have code for it could you send it to my mail thucbv@gmail.com
Thanks a lots.

Ok, Thanks.
This is a protocol used in the Internet. CSMA/CD stands for Carrier Sense Mutil Access / Conllision Detect.

What prevented you to edit the first discussion thread and present a consolidated query instead of giving separate reply-to-yourself style threads?
Also, discussion forums can not be expected to supplant the basic ground work and homework. They only can streamline your basic work, enhancing the output and helping out in your troubleshooting efforts.
I would suggest you give a deep study of Forum Posting Guidelines here: http://www.codeproject.com/scrapbook/forumguidelines.asp[^]

How to get answer to your question:
2. "Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with."
Sorry, I don't know anything about CSMA/CD. But if you want help from those who do know, you better reformulate your question.

Good day.
First, I have to ask, to please excuse my English.
I have an aspx page with 5 comboboxes on it. The 2nd combobox's details is dependand on the 1st one's selectedValue and combobox 3,4 and 5 is dependand on combobox2's selectedValue. Auto-postback is enabled on both combobox 1 & 2.
Whenever I choose a value in combobox 1, the data in combobox 2 gets updated and the first item in combobox2 is automatically selected. The problem with this is that data in combobox 3, 4 & 5 is dependant om the selectedValue of combobox2 and also needs to be updated with the new selectedValue of combobox2, but it does not get updated when the selectedValue of combobox2 changes as a result of the change in combobox1.
The problem exists when a users choice is the value already selected in combobox2, then the data for comboboxes 3, 4 & 5 aren't populated correctly.
It doesn't help disabling of hiding comboboxes 3-5 and only enabling it when the selectedValue of combobox2 changes, because the user will still click on the same value already selected, and the event will not fire.
I also tried adding a "empty" value to the combobox and selecting it as default, but this will lead to a foreign key violation in the databse.
The question is...
Is there a way, that I can (without adding an empty entry in the database - bad practise) set the initial selected item to a blank entry, thereby forcing the user to change the selected index?
I'm currently using ASP.Net 2.0 and the back-end code is in C#. I believe it can be solved with the back-end code, this is why I posted it to the C# and ASP.Net section.I can make use of Javascript, but the application I'm developing doesn't work all to well with AJAX.
Thanks in advance.

Just noticed this is a report from another forum. DON'T DO IT!!
Combobox.Items.Insert(0, "");
Make sure you do this after an databind for the combobox. Alternatively, you could add an item to the collection that you are binding the combobox to. Not the database, the dataset or datatable returned.
only two letters away from being an asset

jdstuart,
ComboBox.SelectedIndex = -1;

Hi all,
I've finally come to the point where I have to start implementing reports in my applications. The name Crystal Reports pops up regularly but I don't know the first thing about it.
Could someone point me in the direction of some online tutorials or something that can get me started perhaps? I'm not even sure where to start.
Also, is Crystal Reports the way to go and what are my other alternatives?
Thanks in advance

Crystal Reports is not bad, you could do worse.
Here's a bunch of tutorials off of google: Clickety[^]
