I am develpoing asp.net web site (3.5) and lately I moved to windows 7. Since then I can't see properly asp.net exceptions and instead of that I'm getting full page with random characters.
View 4 RepliesI'm having the classic (dare I say typical?) error on the ASP.NET production server, which tells me that I can't view errors. Below the error displayed below, are things I've already tried. In IIS Manager (6.0), the application is located under one of the web sites in "Web Sites". It is indeed a web application, as opposed to a virtual directory (it has that gear icon). When trying to view the error from the localhost (i.e. the server itself), it doesn't find the application on its path, even though the root web site works just fine from localhost. It is clearly not a firewall issue because first of all, the firewall is turned off, and second because the root web site works fine from localhost. Heck, I even tried connecting through telnet and that worked fine and dandy too, so it is most certainly and very clearly not a firewall issue. Basically, I just need to view the error at all. I won't have to fix this problem if I can just see the error and fix it, because obviously there is something wrong in the code itself... I just don't know what, because IIS/.NET won't tell me.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".
So what I've already tried is what the error message itself suggests by setting the customErrors thing to "Off". In fact, it always was on "Off" so I didn't have to change anything. I've made sure that the web.config XML is valid. Another common reason for this error is that the .NET run-time is set to version 1.1, not 2.0. I've also made sure that this is correctly configured to 2.0. I'm running it in an independent application pool, meaning that there are no other applications at all, much less 1.1 applications, on the same application pool. I've made sure that EVERYONE can do ANYTHING to the files and directories in the application itself. I understand the security ramifications here, I'm just trying to get it working at all, and then I'll constrain the access rights afterward, one step at a time. But in any case, everyone can read those files.
I have a webapp that turns text to speech and then plays it on a webpage. It's works great when I run it locally but when I upload it to the server I get a security exception.
How can I set the permissions to let me do this? I know very little about permission.

I have copied a DB from one my computers and using it here. On trying to open the page which requires the fetching content from DB, on con.open I am getting this exception:
Unable to open the physical file "E:Program FilesMicrosoft SQL ServerMSSQL10.SQLEXPRESSMSSQLDATAcakephp.mdf". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)".
In Visual Studio, when I test the connection, it says "Test connection succeeded". However, there is one strange thing going on. When I login to the Management Studio, there is no + sign with the newly attached database, as shown.
My site sends confirmation emails from a purchase. 95% of the time, it works. The other 5% after clicking the 'Confirm' button that runs the payment and should send the email, i get the following exception:
Details:
Exception: Failure sending mail.
Inner Exception: Unable to connect to the remote server
Inner Exception(2): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 72.167.234.197:25
The code to send the email is this:
Dim smtpClientPayPalSuccess As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient()
smtpClientPayPalSuccess.Host = "relay-hosting.secureserver.net"
smtpClientPayPalSuccess.Send(mailMessagePayPalSuccess)
FYI: I have confirmed with the hosting that I don't need any credentials, or a different port number than 25. This is also running over https. why this would be happening only a small percentage of the time?

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.

I have introduced site wide exception handling on my site to catch unexpected errors. The event handler sends a message to me when such an exception occurs. But the problem is that any clicks on my site will cause an exception to be thrown with the message: "This is an invalid webresource request."
I googled for an answer and only found a couple of references to 1. setting a fixed machinekey (which for some reason didn't work for me, I got an error saying that the virtual directory wasn't set in IIS, and as far as I know I'm not using IIS at all, I'm using the local development environment and then deploy to a web host) or 2. using a robots.txt file to stop robots from accessing the axd files, but that doesn't help either because it's not robots that cause the problem, anyone clicking around on the page will cause this error. how to solve this problem properly? For now I have handled it by catching and ignoring this particular error by the text in the error message, which works but I would rather fix it so that this error doesn't occur at all.

View 2 RepliesI have been struggling with an issue that sounds like it should be quite common but I can't seem to get the thing working no matter how much I research it!
I am using an AJAX file uploader to upload files (up to 100MB) to the webserver and when the user clicks a button to complete navigate to the next page, I then attempt to move the files off the webserver onto a file server on Page_Load. Both servers are WinServer 2003. There just isn't enough space on the webserver to hold all the uploads once we go live with this solution so I have to get the files off the webserver.
Uploading the file and creating a new subdirectory on the webserver (to hold the file) works no problem at all. When I do the file copy to our file server locally on VS2008, again, no problem. However, when I delopy to the live server and try the same thing, the upload happens ok, but the file copy does not. I get an UnauthorizedAccessException. I don't have access to the webserver myself (but can request it if absolutely necessary) and our file server sits within the same domain (Active Directory).
I do not want to use Impersonation at a high level (web.config), so I tried it programmatically for the purposes of the copy file but it did not work. I used one of our general clerical accounts to pass in the credentials and gave full permission to this account on the file server to create/modify files.
