View 4 RepliesI have made web service, when it is accessed by remote computer to send me the data using this web service then the following errors shows on the remote computer:-
"Server was unable to process request..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)"
I have an asp.net mvc application that spawns a Process as follows:
Process p = new Process();
p.EnableRaisingEvents = true;
p.Exited += new EventHandler(p_Exited);
p.StartInfo.Arguments = "-interaction=nonstopmode " + inputpath;
p.StartInfo.WorkingDirectory = dir;
p.StartInfo.UseShellExecute = false;
p.StartInfo.FileName = "pdflatex.exe";
p.StartInfo.LoadUserProfile = true;
p.Start();
p.WaitForExit();
Before going further, I need to know whether, e.g., pdflatex.exe is a managed code or a native code? Edit 1 I need to consider this because: (Hopely I am not wrong...) Each Asp.net application runs in an separate/isolated AppDomain as opposed to a separate/isolated process. A native executable cannot live in an AppDomain.to be continued.. Shortly speaking, I hope my site does not spawn a new process for each request. Because a process is more expensive than an application domain. Edit 2 My asp.net mvc application allows users to submit LaTeX input commands such as $ax^2+bx+c=0$ to be converted to a pdf file rendering an quadratic equation. Behind the scene, this web app will spawn a process executing pdflatex.exe. The job of pdflatex.exe is converting the LaTeX input commands to pdf document.
Currently we are developing an ASMX, ASP 2.0, IIS 7 web service that does some calculations (and return a dynamically generated document) and will take approx. 60 seconds to run.Since whe have a big machine with multiple cores and lots of RAM, I expected that IIS tries its best to route the requests that arrive in its requests queue to all available threads of the app pool's thread pool.But we experience quiet the opposite:When we issue requests to the ASMX web service URL from multiple different clients, the IIS seems to serially process these requests. I.e. request 1 arrives, is being processed, then request 2 is being processed, then request 3, etc

View 1 RepliesI have an ASP.NET website that worked fine using and debugging in VS2008. I went through the upgrade process opening the solution in VS2010. I can run the site, but as I make changes in the app_code folder classes, they don't seem to commpile and warn me of compile-time errors. As soon as I get to a point that calls the class, the errors show up. Sounds JIT I guess, but this isn't how it was working in 08. Is there an option that was changed in the upgrade process? This is a large project, I really don't want to break something and not find out until some obscure page is opened.

View 4 RepliesI'm getting an exception when trying to access an .asmx webservice within a MVC site. I've tried numerous things like updating the web reference within the console application and building another quick app to test, but can't get passed this issue. If I pull the URL out of the svc variable, I can browse to it directly.

The exception was coming out of the Web Service itself. There were some global variables not being initialized directly through the .asmx call that were being initialized by the application itself.
Some simple checks on variables within the Web Service and setting what needs to be set have fixed up the issue.
I am trying to design my logic to do this but I want to create a dataSet which will have records from several databases, The records all have the same layout.
I am reagin the connection string paths from a table in a database.
I am asking for your help in trying figure out my logic.
Should I use the connectionString builder in conjunction with a loop to Connect, read a record into a dataset Until therer are no more records to be read from my databse table with the database name/paths tables ?
Here is my beginning code which deals with one database:

sbValid.Append("this.value = 'Please wait...';");
sbValid.Append("this.disabled = true;");
sbValid.Append("document.all.btnSubmit.disabled = true;");
//GetPostBackEventReference obtains a reference to a client-side script function that causes the server to post back to the page.
sbValid.Append(this.Page.GetPostBackEventReference(this.btncod));
sbValid.Append(";");
this.btncod.Attributes.Add("onclick", sbValid.ToString());

I have the next problem: I need to process only 1 request at a time from each user. Lets assume that server identifies each user be UserID, sent in query string.cHow can make the server work the way like FIFO (do not start processing next request until the previous is fully processed)? Should I use the named mutexes inside HTTP handler and assign the name to mutex by UserID?
View 1 RepliesI want to be able to run an ASP.NET application when a file is upload via FTP. I understand how to use the filewatcher class to monitor the directory but I don't know where to put the code so it is always running.
Files will be uploaded once per month for each group of users of the system and the next time the user logs on after the upload I would like the application to reflect the new data. I don't want to check for a new upload when each user logs on because the processing could take a log time.
The uploads are automatic from multiple other computer systems and not done by any user.
The Application is hosted (by GoDaddy) so I don't have full control of the server.
Is there any way to have a process running all the time in the background and if so how? The application is written in VB.net.
My web application currently requires users to upload files, after which I take it for "further processing". This processing is VERY time consuming and can take a while before the control gets back to the user. I would like to run this in the background and not have the user wait until this completes.
I know this question has been asked in this very forum before but I'm not able to understand or I'm not able to proceed in the right direction. My understanding is there are a few ways I can go about this
a) create a BackgroundWorker process in my Global.asax file that will spawn a process and take care of the activity.
b) create a web service that will do the processing for me .. (how?)
c) Use Ajax (Again how?)

View 6 RepliesI have worked on many localized sites in the past, using mainy some standard patterns and techniques involving Global/Local RESX files as well as session to maintain currently selected language.
However, it is quite difficult to maintain from a translator point of view, we used a small tool that converts RESX to Excel and then the localized Excel back to RESX, but for some reason this technique doesnt work properly anymore...
better and more reliable tools (paid or free) that can be used to localize RESX and provide translation team a better/easier way to localize content?
Web server running an ASP.NET site that's connected to a sql server instance for all the web related DB needs (products, pricing, users, etc.)...
The companies accounting, inventory control(FIFO, etc.) and whatnot are mainly done on another system which uses a different SQL server...much more complex, for obvious reasons.
What I Need
What I need is to retrieve the current quantity on hand for every product that's on the web by connecting to the internal accounting sql server, even though the website uses a different sql server for it's own requirements.
The reason I can't have the information that is required to calculate the quantity on hand for every product on the web to be on the same sql server is because there are way too many tables that are needed to calculated that information...what's on purchase order, what's on sales order, and the physical inventory.
What is the best way to accomplish this without altering either database?
I have an unknown number of image buttons inserted into a Placeholder at runtime during a webpage's Init stage.
