Is there a way I can retrieve the XML comments associated with the classes as well as methods?
No. Comments are not saved in the compiled assembly. Any documentation found in the source code would normally be saved to a seperate XML file to be used with Intellisense or some other documentation tool. If all you have is the assembly .EXE or .DLL file, there are no comments to get.

As mentioned, it's not possible.
But if you for some reason need a sort of runtime documentation reading you can create your own attribute classes and apply them to methods and read them using reflection.

Netica.IBNet r = new Netica.IBNet();
r.NewNode("dfd", 2, net.ToString());
They are error:

An abstract class or interface cannot be created directly, the implementor must derive (inherit) a class from them to be able to create instances of the interface / class.

Hi,
the most likely reason for this is that you ran out of memory.
arent you creating many and/or big objects every time you cluick that menu item
(in such a way that they dont get disposed and garbage collected when your menu item handler
is done) ??
|
|
|
|
|
how can it run out of memory even if its the very first form i'm trying to open through the menu item after i run the application???
and since its the very first task i perform after running the application there aren't any item or garbage to dispose of, besides this just happens with one particular menu item as all the rest function okay.
any other suggestions???

Hi,
showing the code may be helpful.

You've been using various object and not disposing of them properly when you're done. You can get the OutOfMemory exception when the Windows handle pool is exhausted. Restart your machine and it'll clear itself up.
Checking for handle leaks is pretty easy. Open TaskManager (Ctrl-Shift-Esc) and click on the Processes tab. Click the View menu and Select Columns... Turn on the Handle Count option and click OK.
Now, widen up the Task Manager window so you can see the Handles column. Start your application and find it in the Task Manager Processes window. Look at the handle count. Exercise your application. Do everything you can in it, repeatedly, and watch the Handles count. If it just keeps climbing, your app is allocating various unmanaged resources, like window handles, brushes, pens, fonts, file handles, graphics object, ... and not freeing them properly when your code is done using them. This will eventually lead to the OutOfMemory exception that you got.
A code review is in order. Any graphics-oriented object must be Disposed when your done using it. Any forms displayed with a call to .ShowDialog() must be Disposed. Any file object you use must be Disposed. The list goes on, but those are the most common problems...

What about dispose of brushes/graphic objects? those can also lead to out-of-mem.
|
|

Hi,
answering one question:
everytime you do a "new Something()" of a class Something that has a Dispose() method,
you are supposed to call Dispose() as soon as you are done with that object; if you dont,
you are likely to get memory leaks (which a gc cannot solve for you).

thanks or reply and ur times.
my application started working all of a sudden however i'll have to check for its such unstable behaviour.
Thanks once again

That is if you have created your custom .. e.g if you're creating new Brush objects for paiting custom icons/images on your menu, but left out the dispose part by accident, this is possible.
you could do:
Brush b = null;<br />
try<br />
{<br />
b = new ...<br />
}<br />
finally<br />
{<br />
b.Dispose();<br />
}
OR
using (Brush b = new ...)<br />
{<br />
}
The using expression takes any object that implements IDisposable. I prefer the "using" for cleanliness, and never having to forget the 'dispose' portion in finally.

Any ways thanks for ur time and plz do lookup the second query i've just posted.

I am trying to apply an Asymmetric Encryption (RSA) for file. Since the cryptographic provider needs byte inputs, the server gets overwhelmed typically in case of huge files in the magnitude of 50 MB.
Any pointers towards split and encryption?

Hello,
I am using a WebBrowser control, that is there to display the HTML file. It has some links. The problem is, I don't want those links to change the colour when user clicks on them. I supress the link from poping up, but the colour on the hyperlink changes.
Is there a way of keeping the same blue colour?
Thank you.
|
|
|
|

Here's a style fragment that will cause the hyperlink to always render in blue:
A:link { color: #0000FF; text-decoration: none; }
A:visited { color: #0000FF; text-decoration: none; }
A:hover { color: #0000FF; text-decoration: underline }
A:active { color: #0000FF; text-decoration: none }/ravi
|
|
|
|
|
Yeah, but this has to be done in the document itself. I guess there is no property on the control itself to control the hyperlink colours.
Thanks.
