Web Forms :: Writing A File (doc) To Different Server On The Network?

May 18, 2010

I am trying to create and write a file on a remote server using the below code:

[Code]....

but i am running into issues and getting errors. Below are some tries i have given. My IIS settings are 'Anonymous Access' checked and also 'Integrated windows authentication' checked.

a. As i understand asp.net site would run using ASPNET account, i tried giving full permission to ASPNET account to the folder on the remote server (where i want to drop the file). But i am getting this error - "Logon failure: unknown user name or bad password"

b. The other thing i tried is giving full permissions to 'Everyone' to the remote server folder. But i get the same error as above. But when in my web.config i enable impersonation by using:
[Code]....

then the error goes away and everything works fine as expected. The file gets dropped to the network share.

why the scenario (a) doesn't work because that should work as if i give ASPNET account full access to the folder, and my website is running under the same account, then it should work.

Also, in the scenario (b), i believe it is using my domain account, as the impersonation is true without specifying any username and password and also the remote server folder has Everyone access to full control.
BUT, as a security breach, i cannot use Everyone account to the remote folder. In that case, how can i make this working.

I was also thinking if i can use the virtual directory as the path to the remote folder, something like
http://domain.com/remotefolder but dont know how can i use this approach. Can someone pls share some sample code and the configuration.

Configuration :: Error With Writing To DB On Web Server. A Network-related Or Instance-specific Error

May 25, 2010

I am REALLY stuck with this and need a solution in the next 24 hours .i I have uploaded my asp.net web application to the web and have the database and connection strings functioning and reading the data from the database. But when I try to write to the DB

I get the following error :

Server Error in '/' Application.

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

The wierd thing about this is the connection strings work from the local machine when I run from Visual Studio and I can write to the DB there, I just cannot write to the DB from the URL.

I am pretty new to asp.net but I am sure it has to be something to do with the web.config.

SQL Server :: Writing/Saving DataType Image As File To Disk?

Mar 16, 2011

i need to save multiple documents stored in SQL server as Image type to disk.

What i want to do is "backup" all files in a table (column) to disk, zip them and Response.TransmitFile(FilePath) to client.

I could use C# ot VB but that would require a lot of connections to database or a lot of server memory and i don't want that, becauze there are a lot of files to be saved Since SQL can write files to disk i was thinking about saving those files to disk directly from sql. Something like when u're doing a backup

Web Forms :: Deleting List Item / File - Writing New File With Remaining Items

Dec 23, 2010

Spent ages trying to get this right but am struggling now. I have a list box and textbox, I can happily enter Email addresses into the textbox which are saved into a text file and populated in a list box. I want to be able to select a list item and delete it, along with it's record in my text file. I was going to do it by on the delete list item / button click, it delete's the text file and then writes and a new one with the remaining list items in the list box. Unfortunately it's re-writing the file but either not including the remaining list items. Here's some examples of what I've changed and what populates the text file:

StreamWriter1.WriteLine(Addresses.Items); - System.Web.UI.WebControls.ListItemCollection
StreamWriter1.WriteLine(Addresses.Text); - A blank line?!?

The code is below. The reason I wouldn't allow the user to delete the first list item is because I thought the code was working ok but for some reason putting in a blank line to start with, and if I deleted the line it'd delete all file content. No, I don't know why I thought that either.

[Code]....

where I've gone wrong? I've not actually slept since I woke up at 8am yesterday. It's now 11am... today.

Web Forms :: Writing To Log File On First Pageload?

Oct 27, 2010

Based on this piece of code, I want to do exactly like this demonstration. However, correct me if I'm wrong but if two or more users somehow simultaneously access the web page at the same precise nanosecond in time, then wouldn't we have a race condition? So is this piece of code valid? How would I correct this to make it thread safe?

Web Forms :: File Open From Network Not Download?

Apr 12, 2010

In my asp.net application (an inhouse software) I want users to be able to use files from Network (filepath stored in database). I use the following code to download the files:

string strAttachmentID = ((Label)GridViewNotes.Rows[GridViewNotes.SelectedIndex].FindControl("lblAttachmentID")).Text;
int AttachmentID = Convert.ToInt32(strAttachmentID);
Attachment attachment = Attachment.GetAttachment_ByAttachmentID(AttachmentID);

[Code]....

Is there anyway to open the file without downloading it in a web based application, i.e. open the file directly from the network so when the users edit it and save it, the actual file is changed.

Web Forms :: Writing To A Text File Upon Application Login

Aug 24, 2010

I have the following subroutine in an asp.net application class. The subroutine writes data to a text file upon application login. My question is that if this function was called at the same time by two different users would it cause any kind of error. Is there a need for a try catch?

Public Shared Sub writeToLogFile(ByVal UserName As String)
Dim strLogMessage As String = String.Empty
Dim strLogFile As String = System.Web.HttpContext.Current.Server.MapPath("~/Log.txt") Dim swLog As StreamWriter
strLogMessage = DateTime.Now.ToShortDateString().ToString() " ==> " & UserName
If Not File.Exists(strLogFile) Then
swLog = New StreamWriter(strLogFile)
Else
swLog = File.AppendText(strLogFile)
End If
swLog.WriteLine(strLogMessage)
swLog.WriteLine()
swLog.Close()
End Sub

Web Forms :: Can't Get Image From Network Server

I inherited a web site that has a web page that displays images of properties for an online property/tax info. Using VB code, it searches for a main image then creates and saves smaller images for use as thumbnails. Currently it gets the images from a directory on the web server. The images are copied to the web server via a job from another server on our network. I am trying to code the page to get the images directly from the original server and having trouble doing it. Here's the code. Point of failure is indicated:

Security - Accessing Network Folder With Network Service Account

Aug 17, 2010

My ASP.NET MVC 2 application runs under built-in local NETWORK SERVICE account. I want to set up access permissions for the folder which resides in another computer, but in the same domain. I located that folder right-clicked to open its properties form, clicked to Security tab and pressed Add button which displayed Add user form with correct domain name in the location field. I referred to the account with following syntax:

<domain name><server name>$

because I learned that NETWORK SERVICE account uses machine account when connected to other computers in the domain. However, the system couldn't find the account, so refuses to add the account. Without the domain name it adds a user, but that user seems to be local user, not web server's NETWORK SERVICE account. What am I doing wrong?

By the way, the above syntax worked when I created login for the sql server which is different computer from the web server.
