Visual Studio :: Unable To Debug VB Web Projects On Local Machine / Security Exception Error

Dec 21, 2010

Basically what I am trying to do is have my webpage project folder located directly on my local machine (ex. Local #1). Our database is located on a server (ex. Server #1) . I am building my web applications on my local machine and then trying to debug them in Visual Studio 2008. Only every single time I click to debug my project I get a "Security Exception" error that looks something like the following...

"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.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

I'm somewhat leaning towards the fact that I need to connect to the database to pull information from it and I don't have the proper permissions is the reason why this is happening but I've also read that it can be something that deals with improper configuration of my Web.Config file (i.e. I do not have something enabled).

Note #1: A co-worker of mine is having the same problem if he tries to put the project locally and then debug it. He has full administrative access to the DB and everything else.

if (oops.GetBaseException() is System.Web.HttpRequestValidationException)

C# - Migrating From Website Project To Web Application Project In Visual Studio 2010 Causing All Controls To Throw Error?

Mar 29, 2011

I recently updated my VS2010 website project from .NET 3.5 to 4.0. Everything was working fine in the website project. Today I decided to migrate the website to a web application project as I have learned this is the best way to work in .NET. I split out all my class files into a separate class library and copied all my other content into my new project. Then I updated all the references and web.config.

When I build the class library, everything works great. The problem is happening when I try to build/debug the web application project. It is acting like all the controls are missing and it is also throwing a bunch of compile errors about the public properties I have in my master pages.

Control errors: "The name 'INSERT CONTROL NAME HERE' does not exist in the current context"

Master page errors:'System.Web.UI.MasterPage' does not contain a definition....

It is giving these errors for every single control and master page property in my entire solution.I notice when I add a new web.form to this project, it also adds a filename.aspx.designer.cs file in addition to the .aspx and .aspx.cs file. My existing files do not have these extra files since they were created in a different .NET version.

UPDATE: It seems I was missing the step where I need to right click on the new application folder and select "Convert to web application". I just did that and it seems to be a little bit better...

Now it is choking on Literals that are inside single quotes:

<div class='<asp:Literal ID="CssClassLiteral" runat="server"></asp:Literal>'>

It doesn't see this literal when it does the conversion... Is the above valid code or should I implement that functionality another way?

Configuration :: Error Occured: System.Data.SqlClient.SqlException?

Mar 21, 2010

I'm having a spot of bother deploying my database to my host using the Publishing Wizard. I'm using the .sql file generated along with RunSQL.aspx as discussed in this blog by Scott Guthrie.

The issue I am having is that the permission is set to dbo but this seems to be causing an issue with the hosted database as in I get the following error when I run RunSQL.aspx.

An error occured: System.Data.SqlClient.SqlException: Cannot find the user 'dbo', because it does not exist or you do not have permission. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException

Is there any way to make the Publishing Wizard set the owner to a particular username, i.e the username I use to access the hosted database.

Visual Studio :: Visualizer For LINQ To SQL Throws Exception When Encountering A Timestamp - Rowversion In The Data

Jan 10, 2011

This problem is trivial to duplicate. Do any query on a table which contains a timestamp / rowversion column. Set a breakpoint and examine the resulting query in the Linq to SQL visualizer. Click on Execute which displays the results in a DataGridView. For each row you get "System Argument Exception: Parameter is not valid" when it tries to display the timestamp / rowversion in the grid. What is most annoying is that there is no way to get out of the visualizer without going to Task Manager and killing the Visual Studio process, devenv.exe.

This is definitely a bug. How can you presume to be able to display a database query when you can't display an essential datatype like timestamp / rowversion? Is there any way around this ? I would like to add that in general the CLR is woefully inadequate in the way it handles timestamp / rowversion fields. It would be nice if they could be defined, copied, compared, displayed and serialized in some standardized automatic way.
