Hi,
the real subject would be:
passing a object between two different objects in seperate security contexts using remoting.
but the text wasnt big enought.
I am have problems with the following, i have a remote object that
copies a file from a folder to another folder and this works. Following me
so far?
Once I change the peermissions on the first folder and change the
permissions on the remote object (to allow it to access the first folder)
the application falls with the following error
An unhandled exception of type 'System.TypeLoadException' occurred in
mscorlib.dll
Additional information: No server registered or could not load class for
CLSID {34A8A978-6099-3D6D-BD4D-490CAAB280C3}.
I am new to remoting so i am not even sure that this is a legal action and wither it goes against the windows security model.
Thanks in advance

Hello,
I have the following proglem: I would like to unload the control from the form. After it's removal from Controls collection I cannot close the form. The Dispose method does not get to be called. Just as there was no proper cleanup done. However, the Dispose call on the control does not help. Does anyone an idea how to manage this, to my surprise not easy, task?
All it is done in .NET using Windows forms.
Thanks in advice

He he, I was wondering why there was no replies of rightfull wrath to this. For a moment I thought that there was a team of pissed off CPians on their way to his home for doing some serious "teaching".

The problem was not the Controls unload. It works fine. I was wrong in handling events.
Appologize to everyone I posted the message here. I will be more carefull in the future.

Getting value from stuff you don't own is a compelling
idea. Just think, someone else has created something
that has value, and has made it available to you. You
can now leverage its value in ways that makes all
parties richer. That's the promise of web services.
You need to know about web services. The advent of
standards-based web services marks a new era of
system development. First mainframe, then client-server,
the Web, now web services makes it possible to leverage
every legacy system of the past and do so much more
with your information assets.
Architag Press, a division of Architag International
Corporation, announces the publication of Web Services
Implementation Guide, Volume 1: Getting Started, by
Brian E. Travis and Mae Ozkan.
Sample chapters of the book is available at
http://www.architag.com/press/wsig.
This book will show you what a web service is, and
how you can align your internal systems and external
trading partner interactions to take advantage of this
new concept in system integration.
You will learn about the "Three Steps to Web Services":
* Automate internal systems
* Determine integration points
* Expose integration points as web services
This book is for systems architects, developers,
and I.T. decision makers.
Highlights in this book:
* Written in a light, entertaining style.
* Emphasis on architectural design for web services.
* A tutorial on the state of web services standards.
* Plenty of real-life examples of web service use.
* Tutorials on the key technologies: XML, SOAP,
WSDL and UDDI.
* Code samples of key XML-based web services
technologies and extensions.
* Companion Web site with all code samples and
late-breaking information.

How to write an aplliacation that would
be analogous to Java Applet , but using .NET
(and specificly Windows-Forms)
And how to "instantiate" such an application
on a web page.
I mean that I enter url to html page with
something like codebase tag , and then
the code would dynamically be loaded onto
my computer and working within the browser.
Just like java applet, but using widnows forms.
Thanx

Sounds like your talking about an ActiveX control, I am not sure of any other methods, especially using .NET. Are you trying to accomplish something that asp.net can not handle ??

I'm in the middle of writing a Source Safe automation tool and I have a Traversal method which takes a delegate. While I've used delegates quite a bit in the past I've never really run into the issue where I've needed to pass things along to my delegate that couldn't be found derived during the traversal. IE Checkout delegate needs a checkout destination. I have ideas, but would like some more if anyone has some.

Interesting article on the MSDN site.
Full Eiffel on the .NET Framework
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/ht
ml/pdc_eiffel.asp
Describes the implementation and integration of the full power of the Eiffel
language and method, including Design by Contract, multiple inheritance,
genericity, and other advanced facilities, into the Microsoft .NET Framework
Also shows screen shots of Eiffel running under Visual Studio .NET.

Hi,
I have very simple form with imagelist component and there are some images
in this imagelist. If this form is not the first class in the namespace
loading image throws exception
"System.Resources.MissingManifestResourceException"
Almost all code is generated by Visual Studio. I added only one line:
class NewClass {};
before form definition and image stopped loading. Form isn't localized and
image exist in resx file and
if I comment out NewClass definition or put it after Form1 everything is OK.
Could anybody explain me why this additional line causes this exception?
Thanks,
Damian
namespace WindowsApplication3
{
class NewClass {}; // problem with this line
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.ImageList imageList1;
private System.ComponentModel.IContainer components;
public Form1()
{
InitializeComponent();
}
protected override void Dispose( bool disposing ) {.}
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
System.Resources.ResourceManager resources = new
System.Resources.ResourceManager(typeof(Form1));
this.imageList1 = new System.Windows.Forms.ImageList(this.components);
//
// imageList1
//
this.imageList1.ColorDepth = System.Windows.Forms.ColorDepth.Depth8Bit;
this.imageList1.ImageSize = new System.Drawing.Size(16, 16);
this.imageList1.ImageStream =
((System.Windows.Forms.ImageListStreamer)(resources.GetObject("imageList1.Im
ageStream")));
this.imageList1.TransparentColor = System.Drawing.Color.Transparent;
//
// Form1
//
this.AutoScaleBaseSize = new System.Drawing.Size(6, 15);
this.ClientSize = new System.Drawing.Size(292, 267);
this.Name = "Form1";
this.Text = "Form1";
}

static void Main() {.}
}

This is a known bug; the work around is to place your class at the bottom of the file.

How is the GAC different from the registry? For versioning, wouldn't publicly shared .NET assemblies run into name clashes here just the way the registry did for the same component, different versions?
*->>Always working on my game, teach me
*->>something new.
cout << "dav1d\n";
|
|
|
|
|
to be put in the GAC, assemblies must have a Strong Name.
The strong name includes the namespace qualified name, the version, the culture, and most importantly, the public key.
|
|
|
|
|
No. The GAC makes it nearly impossible to create a name clash with different version of an assembly. An assembly has four parts that make up its place in the GAC.
- Name
- Version
- Public Key Token
- Culture
All four of these items are used to put an assembly into a unique location in the GAC. Try going into the GAC from the command line and not internet exploder. You'll notice that not all of the assmeblies are present at the GAC level as it appears when viewed from internet explorer. All assemblies are stored in the following way in the GAC
c:\WINNT\assembly\GAC\assemblyname\version_publickey\assemblyfile
The culture also goes in there somehwere but i can't remember where exactly. However with the way that public keys are generated it would be extremly unlikely that a product would match all 4 criteria.

Hi, I am looking to get some more experience developing with the new .NET framework, however I am running into a security issue on the Win 2K platform as my sample C# app tries to open my registry - which my system won't allow. I have looked at the .NET framework configuration program under Administrative tools but to no avail.
In short I need a crash course in .NET security. Are there any good resources that can really help me understand it?
Thanks,

I run the program as either myself or the administrator and still receive the same error. I do have permission, and can edit the registry successfully. The program is a sample which I obtained from Microsoft's web site. when I run the application, when I run the program in the browser I get the following error:
Description:
The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
Security Exception:
System.Security.SecurityException: Requested registry access is not allowed:
Source Error:
Line x: mEventLog.WriteEntry(Message, EventLogEntryType.Error ........

Go into your ControlPanel->Administrative Tool->.NET Framework Configuration. I haven't played around with this a lot but from there you can change the access rights of assemblies. One of those options should allow you to access the Registry.
