Problem on security, when trying to put win-form usercontrol on web

[Eitan Mizrahi]

I see a message on:
http://bytes.com/topic/asp-net/answe...tion-please-he

I have got the same problem, which I cannot figure out what is the solution for weeks.

I have Windows 7 (Home premium edition), framework 3.5 (how can I check that, if gacutil is correct version, if it metters, anyway ...)

I am writting on C#.

Also on assemblyInfo.cs :

[assembly: AllowPartiallyTrustedCallers]
[assembly: FileIOPermission(SecurityAction.RequestMinimum)]

On Web.config :

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
        <authorization>
            <allow users ="*" />
        </authorization>
 
<identity impersonate="true"/>
  <securityPolicy>
    <trustLevel name="Full" policyFile="internal"/>
  </securityPolicy>
<compilation>
      <assemblies>
      <add assembly="MyDll, Version=1.0.0.0, 
                        Culture=neutral,
                        PublicKeyToken=..."/>
</assemblies>
</compilation>
    </system.web>
</configuration>
 

Also I have put all of my dlls on c:\windows\assembly.

Nothing happens - same error :

request for the permission of type 'system.security.permissions.fileiopermission,mscorlib, version = 2.0.0.0, Culture = neutral,PublicTokenKey=b77a5c561934e089' failed

This happens when no lines are before the method that calls : InitializeComponents.
When I add the following lines, I see no error (even I don't reach the code of the method that calls initializeComponents) :

[System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Assert, Unrestricted = true)]
        [System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Demand, Name = "FullTrust")]

I have also run caspol.exe.
I don't know what to do with the explanation on the link I gave (Is it necessary to do something with msi installation to check that I am doing right things).

Any help will be appreciated, since I am dealing with the problem for weeks, with no solution.

Thanks :)

If you are developing an ASP.NET application, it is best to use ASP.NET controls.

For example, in ASP.NET you have the FileUpload control which opens a "file dialog" that allows the users to select a file in order to upload it to the server.

I recommend using ASP.NET controls in ASP.NET applications because WinForm Controls require the end user to use Internet Explorer and are not guaranteed to work. WinForm controls are meant for desktop-client development, not web development.

Are you sure about that?
I need to use, at least for a while, user-control on win-form at the old standard (no metter if it is ugly ...)
For java there are applets, so I think there must be an equivalent for asp.net - same as applets.

Thanks :)

Hmm I don't think so...not "applets"

There is Silverlight but I'm not sure if that could help you.

What are your requirements?
What exactly are you trying to accomplish?

Is it really hard to recreate the same looking "old standard" user control using ASP.NET controls??

If your existing control is implemented in layers (UI layer, Buisness Layer, and Data Access Layer) than you may even be able to use the existing code in the WinForms user control to power your ASP.NET control...

What is the most simmiliar to creating web-application as win-form, doing in real C# code ?

Is it WebGui application?
Is it asp.net web application?

Thanks :)

I'd say that an Asp.NET Web Application was the "closest" to win-forms for the Internet; however, they are very different environments.

Silverlight applications are WPF for the Internet.
