I have a procedure in asp.net web site that gives strange result sometimes, I'm thinking to add some code to track it. My question is, in the production environment, is there any way that I can get the calling stacks like the one in the exceptions?
View 1 RepliesI developed a web page using asp.net 2.0 and ajax toolkit on my laptop on Windows 7 and IIS 6. I have my ajax/atlas toolkit DLL in my bin. The updatePanel works fine and does not postback my page. But when i hosted my website on a dedicated server the page postback totally like i have no updatepanel/ajax in my page...
I am using : Windows server 2008, IIS 6Ajax 2.0 installed on the server. I don t understand what is the difference with windows server or IIS or something else?
In my development environment, my CSS loads perfectly. But when I publish the files to the server, the CSS no longer loads.
Originally, when I had this problem, it was because I was denying access to unknown users for all directories. It was also occurring in both environments.
When I fixed that, the CSS started working just fine. But when I publish it to the server, it no longer works.
The website appears to function. I can log in, navigate pages and everything. It's just that the CSS doesn't work.
I checked the permission on the directory and it has access to NETWORK SERVICE, the admin account and IIS_IUSRS.
I have this website with english and portuguese support. In localhost everything works fine and the content is translated based on the querystring parameter named "lang". This chunk of code makes the trick in every page:
protected override void InitializeCulture() {
SetCulture(); } private void SetCulture() {
var logger = Util.GetLogger();
string lang = Request.QueryString["lang"];
if (string.IsNullOrEmpty(lang)) { lang = "pt-br"; }
string sessionLang = (string)Session["lang"];
if (sessionLang != lang) { Session["lang"] = lang;
} logger.Log(string.Format("Culture {0} found",lang));
UICulture = lang; Culture = lang;
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(lang);
Thread.CurrentThread.CurrentUICulture = new CultureInfo(lang);
logger.Log(string.Format("Cultura {0} set", lang));
base.InitializeCulture(); }
Thanks to the logger I can say for sure that this method is called in both cases (production and localhost). I have two resources files in App_GlobalResources folder:
-WebSitemapGlobal.en-us.resx;
-WebSitemapGlobal.resx;
When I try to run my ASP.NET app from my development environment I get the following error message: Compiler Error Message: CS1502: The best overloaded method match for 'mmars.Printing.printFunctions.SetPrintSummaryProperties(mmars.contextInfo, ref mmars.Printing.printObjSummary)' has some invalid arguments.
When I publish and run on our production server I don't get this error.It seems to compile fine when I build from the build menu (in fact if I change the second argument of the bolded function call below, i get a compiler error in visual studio), but now i've suddenly started getting this error message at runtime. So another question I have in addition to getting rid of the error is why is the .NET development server even trying to do JIT compilation on my project if it is already compiled into a DLL?
Printing.printObjSummary myPrintObj = new Printing.printObjSummary();
Printing.printFunctions.SetPrintSummaryProperties(ci, ref myPrintObj);
printObjects.Add(myPrintObj);
Also, though there are no warnings at compile-time, when I get redirected to the page with that first compilation error there are many warnings like the following:
Warning: CS0436: The type 'mmars.MMARSSummaryDataItem' in 'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files

What's the deal with that? Is the webserver complaining about name conflicts in the source file and dll resulting from the source file?
I have read some articles about the new enitity framework and I think it looks very cool from a development perspective.
considering a production environment loaded with data. How does one apply changes to the model? You cannot regenerate the model and in most large organizations, database changes are executed by DBS's and not developers. In such situaitons, it is the role of the developer to develop delta-scripts that the dba can execute.
My experiense with Hibernate (Java) and the like is that you have to pay double when using such frameworks.
Is it OK to use threading.sleep in an intranet web application to display AJAX loading (in production environment)? Off course, the application works fine without it but all works too quick for the end user or even a developer to notice any difference.What is the recommended approach ?

Whenever we have an issue in production, we restore DB backup from our nightly sql backup files in our testing environment. This way we get all data from production.
New Requirement:
Instead of restoring the db which takes upto 2 days, they want to do only selective restore based on few parameters. Requirement is to a build a new ASP.NET page in our application with few inputs. On submit button click, I should select data from prod and insert into testing environment. This involves opening new sql connection.
I am dynamically generating script code to return transaction data to Google Analytics using their ecommerce script. The code that generates the script is fully tested and functional on my development machine and when I view the page code the script, along with any values that were passed to it, can be seen above the </form> tag. Happy days, or so I thought. For some reason the code is not being generated when I test it in a live, hosted environment. I cant figure out why this is the case as the code is quite simple. I simply generate the script code and register it on the client side (see code below)
//Capture the transaction data for analytics ecommerce tracking
//Generate the necessary script code
string strAnalyticsEcommerceScript = Analytics_Ecommerce_Script_Creator();
//Register the script on the page
Page.ClientScript.RegisterStartupScript(this.GetType(), "AnalyticsScript", strAnalyticsEcommerceScript);
The page in question is called "Order-Successfull" and is where customers are sent to when they have succesfully payed for an order. On this page:
-The order is added to the orders database table
- The customer is emailed an order confirmation email
- The google analytics script is generated and registered
The Sequence is as follows:
[Code]....
Whats really interesting is that if I move the Analytics script creator code before the code that sends the emails, the script is generated and can be seen when I view the page code. If I do this, however, the emails do not get sent. If I lay the code out as per the code I have inserted in this post, the emails get sent but the script code is not placed on the page.. The code to that actually sends the emails is quite standard:

I could able to Create sample certificates for client and Server on my local machine and was able to authenticate my client app with the certificates . These certificates are test certificates.
How do I do this in Production. We have a domain certificate from GoDaddy which resides on the server. How do I create a Client Certificate off of that.

At our company we are going to develop more for the Windows platform than we have done up until now. As this scale of Windows development is new to us it would be nice with some feedback from experienced developers. Requirements we have: 5 developers from the beginning. 15 developers a year from now. All developers should be able to develop at the same time. Be able to develop solution for ASP.NET and EpiServer 5. Our idea:
A shared server which developers use for development through Terminal Services. SQL Server Express. Start with some free express edition of Visual Studio, upgrade to a commercial version if we need the additional features. Use IIS and not the web server built into Visual Studio. Questions:
Are we on the right track?
In terms of license costs the above should be cheapest, right?
What do you think about multiple developers doing development using a shared TS-server?
Do you know of any company which has a similar development environment?
Are we going to miss some features of the full Visual Studio version immediately? Is using Express version a bad choice? Is IIS the best choice? If use IIS the developers may use the same port for deployment. If we use the built in web server each one has to set their own port as we're sharing a machine.
Comment answer:
We are thinking about a shared server as it will most likely decrease the license costs. So it's purely a cost issue. We are using CVS for version control. Our situation is that we develop on Mac and Linux, that's why buying 1 server license + Visual Studio licenses seems to be a cost effective way of starting this type of development.
My dev team and I would like to setup a development environment for our ASP.NET projects. BY development environment i do not mean Visual Studio. I mean, that we have a Database Server, a Application Server and a Web Server in a 'Development Environment'. We want to use this as our integration environment. Where the developers all work on there parts of ASP.NET Applications and then we can push our new changes up to test them as a whole. My Question is , what is the best way to deploy our code together without stepping on our toes?
View 2 RepliesThis is a general question about dealing with URL Rewriting in a development environment. I'm developing a CMS to learn ASP.NET/C#, and I will of course need to implement URL Rewriting. This technique is known to me since I've been using with PHP for several years. However in PHP, you can have a local HTTP server, modify the PHP content directly, refresh the page and see the results. Of course in ASP.NET it's not exactly the same, since you need to compile and then publish the code. The problem I have is that I need to check the URL Rewriting-friendly links my code will generate in my development environment - basically, make the ASP.NET Development Server compatible with URL Rewrite. Or maybe not. My question really is: what is the best solution to do that? Use IIS/Apache2 (w/ Mono) for the development server?
View 5 RepliesI'm from PHP background. I used to use Apache, MySQL and PHP for web development. I'm just starting asp.net mvc. I've Visual Studio 2008 Pro SP1 & .NET 3.5 SP1 already installed on my computer. So, I installed ASP.NET MVC 1.0 Created a "ASP.NET MVC Web Application" project when I hit F5 it gives error Unable to connect to the ASP.NET Development Server No wonder. In this process I didn't setup the webserver. Can I use apache here? I guess IIS is the default. Where is it? How do I configure it? What is the WebRoot directory for IIS server? Where can I find it? On searching for "Unable to connect to the ASP.NET Development Server" I found this solution:
Step 1: Select the "Tools->External Tools" menu option in VS or Visual Web
Developer. This will allow you to configure and add new menu items to your Tools menu.
Step 2: Click the "Add" button to add a new external tool menu item. Name it "WebServer on Port 8010" (or anything else you want).
Step 3: For the "Command" textbox setting enter this value: C:WINDOWSMicrosoft.NETFrameworkv2.0.50727WebDev.WebServer.EXE (note: this points to the web-server that VS usually automatically runs).
Step 4: For the "Arguments" textbox setting enter this value: /port:8010 /path:$(ProjectDir) (or any port you like)
Step 5: Select the "Use Output Window" checkbox (this will prevent the command-shell window from popping up. Once you hit apply and ok you will now have a new menu item in your "Tools" menu called "WebServer on Port8010". You can now select any web project in your solution and then choose this menu option to launch a web-server that has a root site on port 8010 (or whatever other port you want) for the project. You can then connect to this site in a browser by simply saying [URL] All root based references will work fine.
Step 6: The last step is to configure your web project to automatically reference this web-server when you run or debug a site instead of launching the built-in web-server itself. To-do this, select your web-project in the solution explorer, right click and select "property pages". Select the "start options" setting on the left, and under server change the radio button value from the default (which is use built-in webserver) to instead be "Use custom server". Then set theBase URL value to be: [URL] But there is no C:WINDOWSMicrosoft.NETFrameworkv2.0.50727WebDev.WebServer.EXE such file on my system. Did I forget to install something?
EDIT:
I'm using Windows XP SP2 and logged in as a user with Administrative previlages. from this [URL]
Disable IPv6
Done
Make sure there isnt an edit in the hosts file for localhost There is no single entry in my hosts file (%SystemRoot%system32driversetchosts) with 'localhost' in it. Check firewall/virus settings to allow connections to/from devenv.exe I tried by disabling the firewall/antivirus If you can preview in the browser make sure the URL in the browser uses the same port number as the port number shown in the ASP.NET dev server taskbar icon. No, Actually there is no such dev server taskbar icon. Try setting a fixed, predefined port in project properties Tried it. But no positive result. S

I am starting a new project. I can either use the Entity Framework 4.0 or Linq to SQL as my data access layer. I don't have any experience using either product. I have read a lot about how Linq to SQL suffers in a disconnected environment like ASP.NET. I was wondering if the Entity Framework suffers from the same problems or if it is works well in a web environment. I was also wondering if someone could recommend a good tutorial or book on the Entity Framework 4.0.

View 3 RepliesThis question is for ASP.NET and SQL Server developers. What are your best practices with respect to setting up your development and test environment? I'm interesting in the following issues: How many tiers do you recommend and what goes on on each tier? Just dev, test, and production or perhaps dev, test, staging, and production? Which types of applications and/or servers should run on actual physical hardware and which can get away with a VM? What are your strategies for loosely coupling users from web sites, web developers from their web/app/DB servers, and DB developers from their DB servers?
How do developers stay "DRY?" What are the pros and cons to putting web, app, and DB servers on their own machines? Does putting servers on separate machines in order to minimize contention for a machine's resources trump any NIC and network latencies that might be introduced by putting them on different machines? How do you configure your web apps to minimize contention for resources (e.g. virtual directories, separate application pools, etc.) How and how often do you refresh your databases on each tier? Do you just refresh the data or both the data and objects?
