I am trying to implement the Ajax HtmlEditor into my application. I currently am using a regular TextBox to load and save some data to some EMail template files and had to do some work-arounds to get it to accept the HTML Input. I am trying to upgrade it to use the Editor, but as soon as I insert the Editor and do a PostBack, I receive the Security Exception below. There is absolutely no change to the code-behind, so I don't understand the issue. There is so little on Google for the Version 3.5 Editor that I'm stumped. I have Debugging enabled, but it won't give me the Soruce Error either.

For a public website what is the best approch to handle the exception and showing to the system administrator and not to the user and what is the best practise followed in most of the ASP.NET sites.
View 2 RepliesI'm getting this exception randomly in one webservice, it used to happen in the first call only, and in the second calls and so on it works fine ... and after a while without use the webservice it happens again. It seems to be that when the AppDomain is not loaded, the first time fails... and subsequent calls are ok; when IIS shutdown the AppDomain... the next call will fail again.

I have been chasing this erorr all day and coming up blank. I created a stored proceudre(fairly complicated logic), added it to the context, and set the return type to a specific entity type.
It generated this:
[Function(Name="dbo.usp_ServiceTemplateSelectByFkID")]
public ISingleResult<ServiceTemplate> usp_ServiceTemplateSelectByFkID([Parameter(Name="FkId", DbType="Int")] System.Nullable<int> FkId)
{
IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), FkId);
return ((ISingleResult<ServiceTemplate>)(result.ReturnValue));
}
I call it from my service with the following method:
public ISingleResult<ServiceTemplate> GetByFkId(int FkId)
{
return Db.usp_ServiceTemplateSelectByFkId(FkId);
}
I have tested the stored procedure and it returns the results I want. When I make the service call from the controller, it doesn't error out, however, it should return 4 records in this instance and instead, it returns the same 4 records (repeating the first record 4 times). .........
After moving my web site from my local development environment to a shared host I get:
Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission your system administrator or change the application's trust level in the configuration file.
The problem occurs in my web application everywhere the following is called:
WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath)
Since my web application is only trying to open it's own web.config file, I don't know why this is flagged as a security exception. Maybe someone can explain... But more importantly I need a solution, the couple solutions I found via Google are painful.
I have (pretty much) the following code in my protected void Application_Error(object sender, EventArgs e) method in Global.asax....
Exception ex = Server.GetLastError();
if (ex is
System.Security.SecurityException)
Response.Redirect("Logon.aspx");
else
Response.Redirect("ErrorPage.aspx");
If I navigate to a page before I log on the exception is caught and I am redirected to Login.aspx as I would expect. However, this is only working when debugging using VS on my local machine.When uploaded to the live environment, the exception is not caught and the user is presented with "Security Exception - Request for principal permission failed."
Using Visual Studio 2005 to create a test ASPX Page using Visual Basic.Simply trying to open an existing file that exists on the particular directory where the ASPX files and the web.config file has been copied.

Anyone had a similar error? I've seach the web / stackoverflow / NHibernate forums but only found people who had a problem when running in medium trust mode, not full trust. I've been developing for several months on this application on this machine with previous versions of Fluent NHibernate and NHibernate.
The machine I'm running this on is 64-bit, you never know that this is relevant.

I am using the standard createuser wizard (but got same issue with other wizard) and in the CreatedUser event an exception is raised causing the wizard not to reach the next step. If no exception are raised the wizard behave as expected. I have tried to force the wizard to move to the next step using CreateNewMember.MoveTo(this.CompleteWizardStep1); as an exemple but still the web page is in waiting stage for about 5 to 10 mins before it finally reach the final step. I have tried to deal with the exception in the routine it occured or throw it back to the CreatedUser event and deal with it there but nothing changes as of to the move to the next step in the wizard.
