Web Forms :: Auto Process In A Shared Environment?
May 17, 2010
We have an app that is on a shared host. I need the app to once a day look at some data and if it meets some criteria, then it would run some code to send out an email to those clients.
Is there anyway to convert any video that has been uploaded by the uplaod control to a flv fromat in a shared hosted enviroment or is there any dll etc to use ?.
My problem is that I'm going to have a SQL Server database and website that accesses that database via a hosting provider, most likely GoDaddy.com, using ASP.Net. I need to make sure the connection string in the web.config file is as secure as possible, because the database will actually be storing trivia questions for a game I'm developing, and the clients will be accessing these questions, saving specific state related details, and other details, to the database, so every player that plays the game will have their details stored in this database. I need to ensure hacking is very difficult to accomplish.
From my research it appears as though the only viable solution for your web.config when you've got a hosting account with something like GoDaddy.com is to use SQL Server security to connect to your SQL Server database and place those details in the web.config file. Is this correct? It seems that this is the most likely scenario for most users, because we don't have access to our hosting providers IIS servers in order to use Windows authentication with SQL Server access and then use DPAPI encryption from there.
i am currently developing an asp.net mvc 2 web application and i would like to create new foldersprogrammatically with access rights, in order to enable loged on users upload their image files.My question has to do with how to assign write access using Directory.CreateDirectory function and assigning DirectorySecurity rules (meaning for which user should i enable user rights, etc...). Note that the hosting envirnoment uses IIS 7.
I'm tearing my hair out here - I'm building a .NET web application at the moment and every time I either want to access the database/build a page or create a new datasource I get the following error:A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)I also get it in SQL Server Management Studio 2008 quite a lot too. I know what you're thinking - search the web for the error, read what the nice people have to say. Only I've spent the last week or so doing this, and I'm no closer to resolving this.
suddenly, with my Visual Studio 2008 I can no longer debugging my web applications (ASP.NET 3.5). I obtain this error: Unable to start debugging on the web server. Click Help for more information. Auto-attach to process [8360] w3wp.exe' on machine 'DELL' failed. The weird thing is that I haven't done special changes to my IIS.
I've developed a popup email .aspx used on our intranet based web app that is auto generated with .pdf's attached. I'm developing with VS 2008 ASP.Net 3.5 C# and System.Net.Mail.MailMessage. I can create and send the email with no issues. The problem is with any attempt to open or delete the attachments I get the above error. The .pdf's a copied with the following code:
FileStream fsr = new FileStream(inFilename, FileMode.Open, FileAccess.Read, FileShare.Read); BinaryReader reader = new BinaryReader(fsr); byte[] bytes = new byte[fsr.Length]; reader.Read(bytes, 0, bytes.Length); FileStream fsw = new FileStream(outFileName, FileMode.Create, FileAccess.Write, FileShare.Write); BinaryWriter writer = new BinaryWriter(fsw); writer.Write(bytes, 0, bytes.Length); // clean up writer.Flush(); writer.Close(); writer = null; fsw.Close(); fsw.Dispose(); fsw = null; reader.Close(); reader = null; fsr.Close(); fsr.Dispose(); fsr = null; Later after sending the email I: mailMessage.Dispose(); mailMessage = null; foreach (string fileName in attachments) { if (File.Exists(fileName)) File.Delete(fileName); }
The error occurs at: the File.Delete(fileName);
how I can delete or reopen these files after sending the email?
My code is that I want to create a log file and log it upon a new user browsing the site. However, what i did was I put in a 6 second delay and then used another browser to access the page. And it threw an Exception saying it is being used by another process which is true. So how come I set it so that, if IT is being used by another process, WAIT and retry every 500 milliseconds until it becomes free/available?
here's the code:
protected void Page_Load(object sender, EventArgs e) {if (!IsPostBack) // if this is the first time page loads, set k to 1 { lognewuser(); }}
I have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.
I have a simple online web system where it possible for the visitors to "play around" with the system. They can like create categories and products and so forth. Everything they create are stored into a database.
What I want is to be able to reset this database with my default values (table data) every n hours.
So for example if we have a bunch of users that have played with the system and created new things. Then I want to be able to make some kode that deletes all data in the tables in this database and fill it with default data. The default data can come from a backup file, or another database with same tables structure or whatever.
I want this task to be done every day at 12 pm or every n hour.
Is this possible (by forexample scheduled webservice tasks or just something as long as it is simple).
If I watch the processes tab in Task Manager on the web server I see "cmd.exe" under the context of 'administrator' but it just hangs. For test purposes c:SendV80s.bat: copy c: oot.ini c:zzz.txt
If I logon onto the webserver's console and execute SendV80s.bat it works and exits without issue. But when I execute the same batch file via the Submit button it gets stuck executing in Task Manager/Process. I believe this has something to do with the fact that cmd is not running in a full environment/desktop context. I just noticed this on the actual console of the webserver (not in my RDP console but console 0 instead)
A pop-up box stating: CMD.exe Application error The application failed to initialize properly (0xc0000142). Click OK to terminate the application. And when I click on the OK button my ASPX page's WaitForExit is satisfied and the continues processing normally.
I know that similar questions have been asked all over the place, but I'm having trouble finding one that relates directly to what I'm after.
I have a website where a user uploads a data file, then that file is transformed and imported into SQL. The file could be up to 50mb in size, and some times this process can take 30 minutes or sometimes even longer.
I realise I need to palm off the actual work to another process, and poll that process on the web page. I'm wondering what the best approach would be though? Being a web developer by trade, I'm finding all this new Windows Service stuff a bit confusing, and I just wanted somewhere to start.
So:
Can I do / should I being doing this with a windows service? if so, how?
Should I use WCF? If this runs under IIS, will I have problems with aspnet_wp.exe recycling and timing out my process?
clarifications
The data is imported into sql, there's no file distribution taking place.
If there is a failure, it absolutely MUST be reported to the user. The web page will poll every, lets say, 5 seconds, from the time the async task begins, to get the 'status' of the import. Once it's finished another response will tell the page to stop polling for status updates.
queries on final decision
ok, so as I thought, it seems that a windows service is the best idea. So as to HOW to get it to work, it seems the 'put the file there and wait for the service to pick it up' idea is the generally accepted way, is there a way I can start a process run by the service, without it having to constantly be checking a database table / folder? As I said earlier, I don't have any experience with Windows Services - I wondered if I put a public method in the service, can I call it somehow?
I keep receiving an exception with the message "Logon failure: unknown user name or bad password". Im absolutelly sure that i'm submiting my correct username/pwd
I have a .NET infra code running both within the IIS worker process and within a desktop client app. How can the .NET code determine whether it is running within an IIS worker process?
I know that I could check the name of the process (w3wp.exe, for instance), but I would like a more robust approach. I wish to make a side note. This is not a production need. I need this information to enable certain scenarios useful during the development and testing phase. Specifically to ease the testing of secure vs non secure configurations.
When I hit the run button (in my Default.aspx), a process starts (this process contacts a webservice to get some files, etc). How do I: Ensure that only a single process is running at a time (i.e. if I refresh the browser, I don't want to start the process a second time)Track progress - there are 4 points of the process (at 25%, 50%, 75%, 100%) that I want to track, and when each part completes, I want to update the progress bar. I have a status object for the running process, but the question is how to update the progress bar automatically? Do I need to use threads to achieve the above two?
I am having the text file which is used to track all the ip address which is available in the network and replace the content from"Reply from 172.29.116.3: bytes=32 time=1ms TTL=255" to 172.29.116.3.
For this task i am having 2 functions 1.runCMD() Function is used to create a file which ping all the ip address between 3 to 254 ("Reply from 172.29.116.3: bytes=32 time=1ms TTL=255").
2.Another function textFileReplace() which is used to replace the text from "Reply from 172.29.116.3: bytes=32 time=1ms TTL=255" to 172.29.116.3.
This process will continue every 30 minutes..
But i am having the error while accessing the function textFileReplace() as The process cannot access the file 'C:inetpub' because it is being used by another process.
I have project in asp.net with sql server backend.i want to auto generate a number for particular column.with the auto generated number i want to insert some other data in the same row same table. on button click event.details

I'm trying to implement automatic lockout after 3 password failure attempts and then to auto unlock after 3 mins. But it does not auto lockout, I can still login if i use the correct password within the 3 mins.
I have a stored procedure which fetches data after joining 8-9 tables and inserts that into a temp table. It was running fine till now, but now when the amount of data fetched have exceeded 20000, the SP is breaking. I have debugged the sp and found that this main query is failing after returning arround 15000-16000 records.
The error message says Transaction (Process ID) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. I know what is deadlock, but when i checked with SP_LOCK stored proc i only found that my process is running on database only. So how is this getting deadlocked when there are no other processes running simultaneously on server.
When I delete all files from the directory path. then it will give me this error The process cannot access the file because it is being used by another process. How to solve this?
