Hello, i've made an applet on .Net 1.1, it's uploaded here:http://arkafon.com/test.html
the applet is Image editor that needs to have the ability to call the Web-Services, as well as load image from the server.
During the initial start it automatically does both of this and i get:
System.Security.SecurityException: Request for the permission of type System.Net.WebPermission
I go to the .Net Configuration 1.1 applet, and do each of these:
a) click on "Trust assembly" and put the full paht to my assembly "http://arkafon.com/ImageEditor.dll"
b) add proper code groups to enterprise\machine\user levels, and tight either to strong name or url, or whatever
none of these approaches doesn't help, what should i do?
can it be caused by my hoster, should i add something to the web.config file?
I try to Evaluate Assembly and it's written that i have unRestricted rights.
THanks for help

You code actually runs on the client-side. The client will not trust your code since it comes via the internet and not locally. I believe you have about the same issues ActiveX applets have.
Anyway, this might help: http://www.developerfusion.co.uk/show/4683/[^]

I've found the problem - my assembly calls web-method and loads image from another host.
I suppose i should write something to web.config on that very server. can you say what?
Also what's the purpose of .Assert(), when i do this:new SecurityPermission(SecurityPermissionFlag.AllFlags).Assert();
before the method that loads image, i get this kind of exception:
"System.Security.SecurityException: Request for the permission of type System.Security.Permissions.SecurityPermission...
Can the user somehow allow this activitiy for this particular app? like saying "Allow this app to do this un-secure activity? Yes\No", or i should always
create the Code group for this assembly?

Hi,
how i can read/write from/into the serial port with c++.Net, i use vc++.Net 2003.
|
|
|
|
|
The .Net Framework 1.1 doesn't directly support the serial port (It is now supported in version 2.0). You will have to use IJW, P/Invoke or a combination of the two. I believe there are some articles on Code Project that deal with this issue.

When i create deployment program in .NET, i used script in custom actions (install) for retrieving existence of older version of that product.

}
If (user click Yes button)

}
If (user click No button)
{
rollback installation from new version
Keep the old version as it is

Using Microsoft Visual C++ .NET (2003)
I would like to put three windows into a Form.
Each window should be resizable inside the

Is the above allowed/supported in the

Many thanks for any guidance/example.

In my app, many threads are created by BeingInvoke now. As all these threads are managed by ThreadPool, I can not get info about these backgroud threads.
So I decided to create a thread manager of my own. In this case all the thread will not be run backgroud. What should I be careful with?
Thank you for your advice!

I have read several articals and started to write my own code.
As I want to keep in track with all the handlers of my threads so as to Abort them when necessary. How to inform my thread manager to remove the handler form thread queue before a thread is sure to finish.
I can pass a delegate to every thread as that the thread can call it just before its end. Are there any other better methods?
Thank you

I have read the article on the XML editor, and although this uses regular expressions to define tokens, I am wondering if there is a easy way to use Lex and Yacc with .NET 2? I am using VC++ and the 2005 IDE. Any help would be greatly appreciated!
Many thanks in advance.

Is there a .NET framework equivalent of lists, vectors, maps, etc. in the C++ standard library?
Thanks,

There are quite a lot of different collections, like ArrayList, HashTable, Queue, SortedList, Stack, HybridDictionary, ListDictionary, OrderedDictionary, StringCollection, StringDIctionary, etc., and base classes to easily make specialized collections yourself.
If you use framework 2.0 you also have strongly typed collections like List<T>, Dictionary<T,T>, LinkedList<T>, Queue<T>, SortedDictionary<T>, SortedList<T,T>, Stack<T>, etc.

I have an MDI Parent form with some toolbars docked to all four sides. I found the MDIClient control in its Controls collections, then I removed it and replaced it with a SplitContainer, placing the MDIClient control in Panel1. In Panel2, I placed another control. The SplitContainer is oriented so that Panel1 is above Panel2, so it appears as though the MDIClient control is now above the control in Panel2 (just like VS2005 appears with one form docked at the bottom).
My problem is this:
The SplitContainer appears to be partially hidden by the toolbars that were already on the MDI Parent form.
Any suggestions/ideas???
