Can't access Class when published

[Guest]

In my design environment this works fine, but when I deploy it I get an error.

I have a class "MessageBox" defined in my "App_Code" folder. My aspx file
contains the line "Imports MessageBox" at the top.

When I deploy and run the website I get the following error.

Server Error in '/' Application.
--------------------------------------------------------------------------------

Compilation Error

[bruce barker \(sqlwork.com\)]

you have two errors.

1) to compile the site with messagebox, you need to add a reference to
System.Windows.Forms.dll
2) the Messagebox class will not work with asp.net due to security issues.
Messagebox requires access to the desktop and services don't have access.

"MessageBox" in this case is a Class that I have defined. It actually uses
the JavaScript "alert" by dynamically building code. It does not use
Sys.Win.forms

code snippet:
sb.Append("<script language='javascript'>")
Dim sMsg As String
While System.Math.Max(System.Threading.Interlocked.Decrement(iMsgCount),
iMsgCount + 1) > 0
sMsg = CType(queue.Dequeue, String)
sMsg = sMsg.Replace("" & Microsoft.VisualBasic.Chr(10) & "", "\n")
sMsg = sMsg.Replace("""", "'")
sb.Append("alert( """ + sMsg + """ );")
End While
sb.Append("</script>")

Thanks.

Hello Junior,

As for the ASP.NET 2.0 web project, how did you deploy it, are you using
the Publish Web site to precompile it or directly xcopy the original web
site to the target place?

Based on my experience, those class & code in App_code can be directly
referenced by any page or usercontrol in the web application with out
explicitly use Imports directive. Did you manually add namespace for the
classes in the App_code folder? Would you provide me the complete source
code file of that Message class and the page that use it? Or if
convenient, you can create a simpflied web project contains the necessary
page, components that can reproduce the issue. And you can send it to me so
that I can perform some local test on it. (you can reach me through the
email in my signature by removing "online").

In addition, here are some web threads I've found discussing on similar
error, you can also have a reference:

Please feel free to let me know if you meet any new problem or there is any
other questions.

Steven,

Thanks for your reply. I have tried both xcopy and Publish. I have manually
added the namespace entry in the web.config:
<add namespace="MessageBox"/>

When I xcopy I get the originally posdted error. When I publish I get the
error:
Server Error in '/' Application

Thanks for your reply Herb,

It seems the compilation of the helper clas code. Based on the error info
you provided when using publish WebSite to deploy the application, it
failed to load the following precompiled assembly:

App_Web_-6w8xwkz

Have you checked the precompiled application's bin directory to see whether
this assembly exists? If not, that means there is some problem occur at the
dynamic compilation that prevent the assembly being generated.

BTW, I also would like to perform some test on my local side, is it
convenient that you create a simplified reproduce project and send it to me
via email?

Please feel free to let met know if you have any questions or concerns.

The dll does appear in the "bin" folder. I will send you a mini project for
you to try locally.

Hi Herb,

I've received your repro package, however, when I try extracting the zip
file, it prompt for encryption password. Would you resend me a unencrypted
one or send me the password also?

Hello Herb,

I've peformed some tests through the test project you sent me, it seems
that I haven't got the exact error you encountered. here is my test steps:

** open the project through filesystem web project

** build and run the project in VS 2005 IDE(test server) , no problem

** Use "publish web site" to precompile the website(updatable) and deploy
it into IIS, run it without any problem

Is this also the exact steps you do in your environment? If so, I think
this could be an environment specific issue. You can also test it on some
other machines to see whether the same behavior occur.

Please feel free to let me know if you have any other finding or if
anything we can help.

Sincerely,
