SQL Server :: Cannot Add MDF File To App_data
Sep 21, 2010I'm using VS 2008 web developer express and SQL Server 2008 express. I created a few dbs using management studio and then created an App_Data Folder in the Web Developer. However, I cannot add the DBs that i created to the App_data folder. I navigated to C:Program FilesMicrosoft SQL ServerMSSQL10.SQLEXPRESSMSSQLDATA and tried to add the DB to the App_data folder. I get the following error:
"The File cannot be added because its being used by another process.
Move SQL Server DB Out Of SQL Server And Into The App_Data Directory As An .mdf File?
Apr 13, 2010I'm currently writing a website in ASP.NET MVC, and my database (which doesn't have any data in it yet, it only has the correct tables) uses SQL Server 2008, which I have installed on my development machine. I connect to the database out of my application by using the Server Explorer, followed by LINQ to SQL mapping.
Once I finish developing the site, I will move it over to my hosting service, which is a virtual hosting plan. I'm concerned about whether using the SQL Server setup that is currently working on my development machine will be hard to do on the production server, as I'll have to import all the database tables through the hosting control panel. I've noticed that it is possible to create a SQL Server database from inside Visual Studio. It is then stored in the App_Data directory.
Does it make sense to move my SQL Server DB out of SQL Server and into the App_Data directory as an .mdf file? If so, how can I move it? I believe this is called the Detach command, is it not? Are there any performance/security issues that can occur with a .mdf file like this? Would my intended setup work OK with a typical virtual hosting plan? I'm hoping that the .mdf database won't count against the limited number of SQL Server databases that can be created with my plan.
Visual Studio :: How To Create App_Data Folder Grayed Out
Sep 29, 2010I have a few questions regarding the "special" ASP.NET folders in Visual Studio web projects.
Adding an App_Data folder in Visual Studio is present, but grayed out in my C# web project, why?
What are the meanings of the various ASP.NET "special" folders?
App_GlobalResources App_LocalResources App_Data App_Browsers Themes - I know this is used to contain stylesheets for a particular theme and is then specified in the web.config or page (if I remember right).
App_Code - Were these classes that were pre-compiled? Do these ASP.NET folders retain their special meaning if you manually create a folder with the same name instead using the "Add ASP.NET Folder" feature in Visual Studio?
ASPNETDB.MDF File Not Showing Up In APP_DATA?
Dec 14, 2010I'm taking Microsoft's walk through on MVC 2 Forms Authentication - [URL]According to the walk through, when I register a user, ASP.NET creates the ASPNETDB.MDF file and it is supposed to show up in my APP_DATA folder upon refreshing in the solution explorer. The problem is, for me it is not and I want to have a look inside so I can understand it's structure.I can continue to run the project and login as the user I created, yet the ASPNETDB.MDF file is still not visible under the APP_DATA folder.
View 1 RepliesConfiguration->Security Page Fails To Create AspnetDB.MDF In App_Data Folder On Windows 7
Feb 12, 2010I am having problems getting the security.aspx to load up on my primary development computer which is using Windows 7 Ultimate and Windows IE 8. Clicking on the ASP.NET Configuration icon from the IDE in the Solution Explorer within Visual Web Developer 2008 Express Edition loads up default.aspx with no problem. But when I click on the "Security" hyperlink to access "security.aspx" I get a message along the lines of "The configured SQL data source provider is not properly configured". It goes on to state a list of potential reasons for this problem. One that includes not having the proper credentials or permissions. Im almost 100% sure it has something to do with permissions because I can't even get to the "security.aspx" page from opening a new empty project. I have recently installed Visual Web Developer 2008 Express Edition on my laptop which is running Vista with all latest updates and this issue does "not" exists. I can click the "ASP.NET" icon, load up "default.aspx" and click "Security" and it loads the page with absolutely no issues.
I have discovered a weird workaround but I don't like having to do this. If I add the following lines to my "web.config" file from any given project I can get to the "security.aspx" page without getting any SQL messages about improper configuration or permissions.
<<remove "LocalSqlServer">
<add
name="LocalSqlServer"
connectionString="data
source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"
providerName="System.Data.SqlClient"/>
Basically, what I have to do to get to the security page to load without error is add a remove statement and then I just cut'n'paste almost the exact same connectionString from machine.config in the Microsoft.netFrameWorkV2.0.5027config directory. This does away with the "Improperly configured SQL datasource message" and gets me a new error message along the lines of "Could not create a SQL instance". My memory is fuzzy on exact error messages since Im not at development computer right now. However, when I change the User Instance attribute from true to false, then I have success at last.
Reading Static File From App_Data Folder?
Apr 23, 2010I have put a css file in App_Data folder and referrenced it properly in the page to be used. But when I browse the page then it does get loaded and page is shown without styling. Well I know why it is happening because Asp.Net run time blocks access to App_Data folder at run time. But I wanna ask that how we can make it working that is I put the css file in App_Data folder and it still works.

App Data - Getting Access Denied Trying To Read A File In App_Data In A Project?
Jan 24, 2010I've an XML file stored in App_Data which is only used to read some configuration on startup. When I attempt to open it within my code, I get an Access to the path ... is denied message.
I'm having trouble understanding why, and how to solve it. I guess in theory I should alter the permissions on the file (and directory), but this hasn't changed anything.
To give a bit more background:1. Its a file bundled with the project, so the setup created by VS2008 writes it to the correct place during install. I didn't think I'd need to do anything unusual post install such that the ASP.NET application would have access.
2. When I've tried publishing this locally, I've not had any problems. - This is only on a test Windows 2003 server.
3. I've ran a simple page to understand the effective user of IIS - It is NT AUTHORITYNETWORK SERVICE. I tried granting "Full Access" to this user to this file, and still it doesn't work.The code to open it is simple:
FileStream fs = new FileStream(Server.mapPath(s), FileMode.Open);
Where s is defined as '~/App_Data/myfile.xml
I've even copied and pasted the full path & filename (from the exception) and tried "dir" on it, and it is indeed present (to get around a typo for example).I've also tried running aspnet_regiis.exe /s

Web Forms :: Create PDF File In Server Side?
Aug 29, 2010I need to create a .pdf file which can download by client clicking on the link in my web site. That pdf should be generated using stored information in database. It has different types of fonts which has not installed in client machine and only installed in web server.

C# - Create A Server Control On Another ASPX File?
Apr 15, 2010I am developing a C#/SQL ASP.NET web application in VS 2008. Currently, I am transferring control from one ASPX file to another:
if (uploadFile.PostedFile.ContentLength > 0)
{
inputfile = System.IO.File.ReadAllText(path);
Context.Items["Message"] = inputfile; //Page1
Server.Transfer("DataMatch.aspx"); //Page1
}
However, it fails on this Server.Transfer line after inserting runat="server"
in the DataMatch.aspx file to the Table element like so:
<table width="50%" id="tMain" runat="server">
But after making this a server control, I rebuilt it and now when I run this app it gives me exception:
Error executing child request for DataMatch.aspx
But I need this table to be a server control so I can make it invisible programmatically if a certain condition occurs. How else can I programmatically make this table invisible?

SQL Server :: Create A Relationship Between Database Table And Xml File?
Mar 17, 2011I've just taken over looking after a website and well to be honest the way it's been put together is not the best, but I have to make do as the client does not have the money to make major changes.Anyway currently there is data stored in a MsSQL database and some in an XML file. The xml file does have a ContentID attribute which matches the ContentID in a table.Not really done much with XML as I tend to use a database and LINQ.What would be the best way to tie these two together so I could output the results in a gridview for example.
