I want to write an .xml file using the following code into the App_Data/posts, why is it causing an error:
Stream writer = new FileStream("..''App_Data''posts''" + new Guid(post_ID.ToString()).ToString() + ".xml", FileMode.Create);
If there is a self contained web app, let's use the Screw Turn Wiki as an example, that utilizes the App_Data to store the MDF, is there any way another web app, living in the same domain, can also use that MDF?
Example IIS Setup:
http://wiki.domain.com | c:webwiki | port 80
http://www.domain.com | c:website | port 80
My WWW web app would like to pull some data from the WIKI app. Without moving the MDF to a full fledged SQL Server is there a way to do this? Also note, the WIKI app is an installed app so I don't have access to its source.
My Microsoft Access DB file is in APP_DATA folder. my server is Windows 2003 and I like to know how is the best way to protect this file.
so which one is safer ?
./wwwroot/App_data/Database.mdb
or
./db/Database.mdb
I'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
I want to show my data on an ASP.NET page using C# in XML format
<person>
<email>a@a.com</email>
<dob>YYYY-MM-DD- HH:MM:SS</dob>
<city>XYZ</city>
</email>
</person>
Do you have any code with examples.
I have a page with a gridview on it. It selects rows relevent by using a querystring id passed on from the previous page.
From this gridview, i want to write only the displayed rows to a .txt file. How can i do this?
I'm trying to find out if there is a shorter way of writing data to a view than what I am currently doing. This is what I currently have in my view:
<td>
<%
if (Model.AnnualIncome != null)
[code]...
Is there a shorter way of displaying annual income to the screen than having all the <% %>?
I have a hidden input on my form, and my JavaScript code writes there dynamically generated string based on the user behavior on the page.Later, I access to that inpput via server side code.Many users will be using this page at the same time, so what about thread safety ?I mean, could it be possible that userA has an access to that string generated by userB ? Or maybe server will read that string from each user's Web Browser ?
View 2 RepliesI have an ASP.NET app that writes binary data to a SQL database. It worked fine using SQL Express, but does not ever write the data using SQL Server 2008 R2. SQL Profiler shows the binary data in the UPDATE query, but nothing happens... no errors, no data saved. Does anyone know what I'm missing? Other data types work fine.
My data type is VarBinary(MAX)...
i have write data from db to .txt file,where db have large amount data,i need to wite data into file, if some error occure, then reInitiated that file and write data again without stop process.that is Continuous calling same process
View 2 RepliesI was just wondering that when we insert some datainto database we can use the following method.
create a sql datasourse ,
set the conection string,
set the insert comand type,
set insert parameters,
and Set the SQL Statement like
sqldatasource.insertStatement="insert into tablename(field1, field2) values(@parameter1, @parameter2)";
and then call the datasourse insert() function,
this method is usually used for single line insertion at the end of the DB.
Now I am a starter in asp.net c#,
I want to know that if There is a way that I have lots of data like some XML file that have the same table structure as the SQL database table
and I want to write that data to the database, HOw to do it Properly,
I can Still achieve the required results by iterating through XML datarows and for each row conecting to db and inserting and then disconecting dfrom the db,
But I want to know that if there is a way to do it in one go meaning I have to conect to database only one time,
Note: I already have some data in my SQL table, there are three fields(ID Name and Nickname) the ID(primary key) is INT type and auto incremented, the name and nickname are strigns.
the xml file has the structure
<userdata>
<user>
<name>michel</name>
<nickname>micho</nickname>
</user>
</userdata>
If i have a server with ASP.NET 3.5 installed, where no one explicitly installed SQL Express. Can my web application still connect to an MDF file in the App_Data folder
View 1 RepliesI've noticed that ASP.NET automatically creates an App_Data folder for you whenever you make a new webforms application.
Since all of my data comes from a SQL Server 2005 database server, is there any reason to actually keep this folder?
i tried to add sql/server database file to app_data and i got this error
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.

I have a web page (Provider) that creates an XML file to be send to the Requester in this fashion:
1. A Requester page needs to send an XML file to the provider page
2. Provider will read the XML file to authenticate the request

4. Provider will send the xml file back to the Requester.
Can anyone provide sample code for both the Requestor page (step 1) and the Provider page (steps 2 & 3)
I'm looking for a quick way to log some data - I seem to remember a way to write to the access log, similar to System.Out.Println() but I can't seem to remember how to do it.I can't attach a debugger, nor can I add additional information to the web app via Response.Write().Is there a simple way - a single statement with no configuration changes would be ideal - to write to either the error or access logs?
View 1 RepliesI would like to read from a data reader (or other) and write to a grid of some kind one row at a time in a loop. I prefer this rather than load a data bound grid control all at once. I need to do this because I have to perform some calculations on the data before writing each row.

Pardon if this is a very dumb question, but I was trying to migrate an existing ASP application to asp.net MVC, and followed the procedure from the music store tutorial (http://www.asp.net/mvc/tutorials/mvc-music-store-part-4), which involves adding the
database to the App_Data folder. (I had to restart my machine before it would work, since otherwise, Visual Studio thought the database was being used by another application.)
Now when I check in Windows Explorer, it looks like the database file was literally copied into the App_Data folder, and now I have two mdf files on my hard drive with the same name. What is going on there?
Will my MVC app ignore the original (real) database and use it's own private copy instead? (That would be bad.) Or is the new copy just for reference when using wizards that generate entity classes etc.? If the latter, what is the procedure when the real
database is modified, to update the application code?
I used aspnet_regsql -W wizard approach to create DB for membership tables. and added script as follows in web.Config
[code]....
I am confused as to what to do with these. I have .cs files in App_Code. I also have other files in App_Data, and Bin. Could I just create these folders, make them virtual directories and upload my files as normal? Or do I need to do something special with these folders/files? Im really stuck on this. Also, this is a "shared hosting" account.
View 5 RepliesI'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.

If this is done, what steps do I need to follow to use the database on the new machine? Do I need to change web.config or what more?
Unable to add 'App_Data/Database.mdf' to the Web site. Could not find a web server at 'Mysite.com' on port 21. check to make sure that the web server name is valid and your proxy settings are set correctly. If you are sure that everything is correct, the web server may be temporarily out of service.
