I have searched for two weeks, every night, exhaustively reading forum threads and trying all suggested solutions no matter how outlandish. Just as is the case with the many many forum threads about this same issue, the site works fine on my development machine. It deploys with no errors. It works from the production server and reads data from the database, but when it attempts to access a profile it crashes with this error.
A number of posts say to check or uncheck an option called "remove app_code.compiled file" but apparently this was a Visual Studio 2005 option. It is nowhere to be found in Visual Studio 2010. A number of posts say to make sure the App_Code.dll is present in my bin directory. It is present. I've deleted the app_code.compile file manually to see if that made any difference. I've changed the target framework from 4.0 to 2.0 and 3.5. I've completely deleted the site in IIS, created a different folder with a different name and redeployed the site with every combination of "allow this precompiled site to be updatable" and "Use fixed naming and single page assemblies".
i've included references to System.Web.Profile and System.Web and System.Web.Profile.ProfileCommon. I've created a new, fresh website targeting .net framework v4.0 and copied that web.config file to my application and recreated my profile entries to ensure that I didn't jack anything up in the config file along the way.
I'm using VS2010, vb.net, .net framework 4.0, and SQL Server 2008 Express on Windows 7 Pro with all updates installed. I have developed a website that uses memberships, profiles, and roles. I allowed the built in providers to create the aspnetdb.mdf file for me in the App_Data folder. I added a number of my own tables to aspnetdb.mdf so I would have a single database for all my site's data.
I am hosting the site on my own server. It uses Windows 2003 Server, IIS 6, SQL 2008 Express, and all of my software including the OS is up to date with the the latest servicepacks, updates, and all of the .net framework updates including 4.0. There are no updates left to install and I'm sure that my issue isn't due to a missing update or framework version.
I copied the aspnetdb.mdf and .ldf files from my app_code folder to the sql server express folder on my server and attached the database. I do this because I don't want the file to autoattach, because I will likely use a commercial hosting service in the future. I added a sql server user with ownership rights to the DB. strong text
I then modified my connection string in web.config to point to the UNC of my SQL Instance on my server and to authenticate with the sql server username and password that I set up with ownership rights to that database. I updated my membership, role, and profile providers in my web.config file to use the new sql connectionstring and I was sure to include the application="/" setting and to use before each provider.
I can run the site just fine from my development machine. I can log on to it and use all of its features. However, when I publish the site to my server I can access the site, both locally over my intranet and over the internet. I can navigate around on it and it retrieves all of the data from the tables that I added to the database myself, but when I try to log on to it or to create a new account (basically anything that uses memberships, roles, or profiles) the site crashes with the error and all of the data below.
I've checked to verify that the application name in my aspnetdb database is in fact simply "/". I've ensured that I'm running from an application pool that is using the 4.0 framework. Much of the googling and reading that I've done seems to indicate a problem with my providers, but I can't understand why it works perfectly on Casini (or whatever the development server is called) on my local machine but crashes on my web server. In both cases they are connecting to the same database.
I would be so grateful if anyone could tell me what I'm doing wrong here. Following are the full error displayed by my server when the site crashes and also what I feel are the relevant sections of my web.config file.Full content of error message and relevant sections of web.config are below:
Server Error in '/' Application.

I am creating a simple VB.NET WebBrowser to automate and simplify navigation of a web site. However on certain pages i get the following popup message. This is telling me about an error which is on the Web Site itself and thus out of my control.
Is it possible to block these popups from my application?
The application is for personal use, so auto-clicking yes would be an acceptable option.

Kindly include what kind of exception that would be as well.

For testing purposes, I write a lot of alerts and error messages into a .txt file (some 15 entries per second). At the end of the day, the txt file becomes very large. I am now getting confronted with data loss in my application (threads indicated as being busy). Could it be that my entries in the Log.txt are slowing down my application to the point that the latter becomes unstable ?
View 2 RepliesThis is kind of two questions (one more specific than the other).If I have a method like this:[code]Can I qualify Foo against another type (for instance can I require that Foo be a String that also implements IInterface?).I'm imagining something vaguely similar to this:[code]Additionally, is there any way to qualify the Type parameter?For instance, can I require that the Type I take as a parameter is of a particular class tree?I should mention that I am using this in the context of a property of an attribute so the class declaration itself cannot be generic (this is purely focused on qualifying a method parameter rather than typing a class and its methods).
