I agree with you Chris. I should read up and first try myself before asking for help. My mistake!

Hey,
What is the future of entity framework and LINQ? I am looking for a decent framework for database persistence. I tried Codesmith tools and .NET Tiers templates but the learning curve was huge and the support was almost non existent.
Any suggestions what is a good option to use?
Regards,
Brendan

Are you trying to access/save any file on page load?

I am writing to error log file in one of the folders in the application
|
|
|
|

Can you post the line of code.
|
|
|
|

public static class clsSystemUtilities
{
public static void WriteErrorToLog(string errorDesc)
{
string logFileName;
StreamWriter strWriter;
logFileName = ConfigurationManager.AppSettings["ErrorLogFileName"];
if (File.Exists(logFileName))
{
strWriter = File.AppendText(logFileName);
}
else
{
strWriter = File.CreateText(logFileName);
}
strWriter.WriteLine();
strWriter.Write(errorDesc);

I'm on my last nerve with this. I have been working for over 6 hours trying to figure out how to get this to work. Here is what went down:
I created my site, which is esentially just a database of people who work for me, their positions, ect. I created it offline, using Visual Studio 2008 Professional, and created the database under SQL Server 2005. I went to upload all my files, and my databases were stored in my app_data folder which was also uploaded. I have an app_code folder with my datasets in them.
Here is what my code looks like for...
web.config:
<?xml version="1.0"?>

I gave all the code I have, and am seriously considering giving up on this whole project. The thing is, the code works fine when I test it on my PC, but the minute I upload it online and go to my website I get this error:
Server Error in '/' Application.
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 <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

Please help me, I'm going literally insane by not getting this to work. Any help is greatly appreciated. I've done a great deal of searching and nothing has helped me.

It seems that your application is not able to connect with the SQL server database from within your application.
Check the SQL server connection string in your web.config.
|
|
|
|
|
<add name="ConnectionString" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|database.mdf;User Instance=true"/>
That's it. I don't know how else to go about doing this. I have MS SQL database support on my hosting, I just don't know how to get it all working. Right now the database is just in the app_data folder.
|
|
|
|
|
Is your SQL Server database in the App_Data folder of the web application.
You are using Windows Authentication to connect with SQL Server dataqbase.
The ASP.NET application will run under Network Service account in the server. Therefore you need to provide access to the Network Service account to your database.
|
|
|
|
|
I'm completely confused. I'm new at this whole thing, what do I need to do, in detail, to get it to work?
Basically I am running on a server that I do not own, I just host there. It has Plesk control panel on it, and it allows me to create MS SQL databases and such. No idea.
|
|
|
|
|
If the server allows you to create SQL Server database,
Which connection details are you using?
The same connection details should be put your web.config file.
|
|
|
|
|
I don't have any connection details, I have a Plesk control panel, that allows me to create either an MS SQL database, or a MySQL database, all I know is that you create a database, in my case it would be erik_database, and a username, in my case I created it to be simply aspadmin, and that's it.
|
|
|
|
|
I assume that you have used SQL Server database in your application.
How do you create SQL server database in the server. Using SQL Management Studio?. if so, then you can see the server name, database name and also you need to enter password.
Assume that erik_database is name of the SQL database and aspadmin is the user name, 'YourServerName' is the server name, 'YourPassword' is the password to be used connect with database, then connection string in your web.config should be as below
<add name="connectionString" connectionString="Database=erik_database;server=YourServerName;Uid=aspadmin;pwd=YourPassowrd" providerName="System.Data.SqlClient"/>

What is the common port for a MS SQL server?
|
|
|
|
|
|
I got my apps to connect, but now it's strange because every time I go to my site a username and password dialog shows up, and I can't even login. Odd.

Hello,
I'm working on a simple ASP .NET health checker and I've run into a few obstacles.
1) I need to be able to get the full non-paged memory usage from a remote machine (on same network). I've tried using System.Diganostics.Process.NonpagedSystemMemorySize64 however I've come to realize that the kernel's nonpaged usage is going to be missing from that total. Here is a quick sample of what I was doing:
Process[] myprocess = Process.GetProcesses("computername");
foreach (Process p in myprocess)
{
nonpaged += p.NonpagedSystemMemorySize64
}
2) I can overcome that locally by using System.Diagnostics.PerformanceCounter however you can only access the API for that class locally. Is there another class that would suit my needs?
Any help would be appreciated.
