i have just started working on .net remoting . well, an event is raised on some method call in the remote object. But while i assign a handler to the remote object's event property a SecurityException is raised stating :
"Type System.DelegateSerializationHolder and the types derived from it (such as System.DelegateSerializationHolder) are not permitted to be deserialized at this security level."

Hi,
Just happened to see that same error yesterday...
check out this link http://www.codeproject.com/useritems/RemotingEvent.asp
Section solution 2.
When you implement a wrapper class which can be accessed from both client and server side you app should work
Greetings

Hi.
This is because of the remoting security. Normally types that are in GAC-registered assemblies are allowed to be serialized and deserialized, unless they're derived from:
- System.Runtime.Remoting.ObjRef
- System.DelegateSerializationHolder
- System.Runtime.Remoting.IEnvoyInfo
- System.Runtime.Remoting.Lifetime.ISponsor
you have to set the typefilterlevel to "Full" in your channel-configuration.
for more information take a look at this: http://msdn2.microsoft.com/en-us/library/5dxse167(vs.80).aspx[^]

Dear all,
Probably is the answer pretty obvious, but I have been struggling with this for the past 2 days already, and it's making me frustrated.
I got following XML file
<br />
<?xml version="1.0" encoding="ISO-8859-1"?><br />
<things><br />
<people><br />
<person id="1"><br />
<name>Bob</name><br />
<age>25</age><br />
<projects><br />
<project x="123" y="123">ABC</project> <br />
<project x="53" y="149">DEF</project> <br />
<project x="13" y="111">FOO</project><br />
<project x="463" y="435">BAR</project><br />
</projects><br />
</person><br />
<person id="2"><br />
<name>Steve</name><br />
<age>100</age><br />
</person><br />
<person id="3"><br />
<name>Maria</name><br />
<age>23</age><br />
<projects><br />
<project x="1" y="1">HOT</project> <br />
</projects><br />
</person><br />
</people><br />
<file><br />
<name>filename.ext</name><br />
</file><br />
</things><br />
How can I add in C# a new person, and acess the "people" node.. I even cut away so much code, that I ended up with following, just to print out what's in there, and it even fails:
<br />
doc = new XmlDocument();<br />
doc.Load(this.filename);<br />
XmlElement rootPeople = doc.GetElementById("people");<br />
XmlNodeList node = rootPeople.GetElementsByTagName("person");<br />
for (int i = 0; i < node.Count; i++)<br />
{<br />
Console.WriteLine(node[i].InnerXml);<br />
}<br />
I have been messing with Xmlnodelists, xmlelements, xmlwhatevers, but even after reading the first 2 pages of google results, it still doesn't seem to work..
Can somebody point me in the good direction?
Thanks,
mike

First of all, I suggest using the SelectNodes and SelectSingleNode methods instead of GetElementsByTagName since both use XPath expressions and therefore allow specifying/restricting the selection in more detail. You can for example select the (first) people node by writing
XmlNode peopleNode = doc.SelectSingleNode("//things/people");
To create a new person or more general new nodes in a XML document take a look at this Create New Nodes in the DOM[^].

Thank you Stefan, works like a charm!!
Seems that, after reading your signature.. the universe is building improved versions of me 
Thanks again.

I have a problem like Yanshof.
I have a class writed in C++ (I don't want to translate it), it is used to store and processing te data...but the interface of the program must be writed in C# (or VB).
It is possible to do this in a simply way (using Visual Studio 2003 .NET?) ?
How to create this solution that contains this classes in different lenguages.
Y/N ?
If yes, does anyone can show me the way, I need only a simple example (the classic "hello word" in mixed lenguage is enough)
Thanks a lot
Cheers,
Russell

A very simple way is to set some of your procedures written in C++ as exports. And using DllImport attribute in C# you can use those exports

First, thanks you for your reply.
Yes, of course, using dll I can export the 'procedures',.... but this is not exactly what I need: I need to use an entire class, his member functions and (expecially) his member variables.
I am hoping that it is possible to create a unique Visual Studio solution composed by 2 sub-solution, one (written in C++) that contains the document and the other (written in C# or VB NET) to visualize this document.
But, unfortunatly, I'm going to think that it is not possible, nobody is confirming this 'dream' to any of my posts.
Let me know
Cheers,
Russell

Use the Form.Closing event for this where you can set the CancelEventArgs to decide if the form will actually close. However I don't think that works if you end the process via task manager.
|
|
|
|
|
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
e.Cancel = true;
}
When you close it with taskmanager from the Applications menu, this event is also fired, but not when you close the underlying process via the Processes panel.
Visual Studio can't evaluate this, can you?
public object moo<br />
{<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

Exactly - Someone else could have benefited from the thread if they had a similar problem.

Hi Friends,
I have a problem may be any one of you guys could help me. I am developing an online watch Movie Website. Here I need a script which can check after every (let's suppose) 5 seconds that whether user exists in database or not. Although I am using c# but I need a solution no limit in which language it is (c#, javascript, vb.net).
I can check it simply to "Refresh" page after every 5 seconds but me and my client don't want this. Once before this I posted same kind of question but still no answer. I hope to get this time.
CHEERS

I don't believe you. You have a flaming cheek coming here and claiming that you haven't had an answer.
I told you before[^] what you need to do. No, I didn't give you the exact code to do it, but I did tell you how to do it - and that's the most that you should expect of people. We're here to help, not to actually write the code for your client for you. I even gave you the JavaScript that you would need to use to fire the refresh without doing a postback.
Don't come onto these forums and lie about the lack of help you got. Frankly, I'm insulted and disgusted.
Deja View - the feeling that you've seen this post before.

Listen Mr.
What do u think If your code works then Am I crazy that I have an answer and I am coming here again and again to insult you? Do we know each other? Ofcourse Not. I am not asking you to write code for me. I tried code which u sent me even then I need to refresh page. One more thing I think this is not your personal forum. This is second time you are replying me in this language. I said you "Sorry" that time as well and saying again. I am Sorry.
if you think I am just insulting you please give me a favour never ever reply next time to my Thread. Thanks a lot.
