I am trying to convert an ASP.NET website into a web application project. The conversion has gone ok I think apart from previously I had 2 xsd files in the App_Code folder. I believe this folder is not used in web applications projects, so where would I put xsd files now.
I don't think you have to put them anyplace in particular. For the purposes of organization you could create a data directory. If the project is small enough, I leave it in the root.
You can place the files wherever you want, but you have to be careful that your namespace references are still correct.
I would look at your Root Namespace declaration in the project properties to ensure that it is set to what you expect it to be. Also, you will want to look at the location of your TableAdapter objects, as that is where the actual error is, not in the declaration of your StudentQueriesDataTable (Referenced by your xsd as the posted question)

I converted a web site project to a web application using this guide
http://msdn.microsoft.com/en-us/library/aa983476%28v=vs.100%29.aspx
In the guide it says that I have to add namespaces to my classes but I did not do that. The classes I have in the Old_App_Code directory are not placed into namespaces and the application runs just fine (tested on different machines). Is it because there is something special about Old_App_Code or am I missing something? Thanks.
You are misinterpreting what the guide is saying, it is NOT saying that you need to add namespaces to get the code to compile, but rather that the conversion process does not add the namespaces into the code files by using the folder/file naming constructs.
The guide is further underscoring the fact that when you add new items (i.e. classes) in a web application versus a web site; the namespace is automatically added to the code file, based upon the folder structure and file name of the of new class.
In a dynamically compiled ASP.NET Website project, can the assembly for the App_Code folder be explicitly named?
For example, under regular circumstances when I run an ASP.NET website the assembly name generated into the Temporary ASP.NET Files\ folder is partially randomized like App_Code.neizakfo.dll where neizakfo is the portion that can differ. Can I explicitly provide a name for the assembly like App_Code_Web1.dll?
Clarification
By business requirements, the website cannot be precompiled/deployed. Therefore I'm seeking a solution in context of the Temporary ASP.NET Files folder and dynamically compiled assemblies as noted above.
Background:
I came across this question while looking for a way to perform dynamic type instantiation on a class in the App_Code folder of a website using an assembly-qualified name stored in configuration, but instantiated from the web page, thus crossing an assembly boundary. Because the web page and app_code code are compiled into two different assemblies by default, the Type.GetType(..) method's default behaviour of searching for the Type name either in the current executing assembly (the web page) or in mscorlib doesn't suffice for picking any Type from the App_Code assembly. Being randomized, the app_code assembly name is not known for me to include in the assembly-qualified string.
I can put the data Type in a class library (because that does have an predefined/exact name) to get rid of this problem, however I'd like to know how to do this inside the website itself without creating a class library project for the purpose.
You can sort of do this in a WebSite project.
There's an MSDN article on using the -fixednames flag when compiling the project.
This effectively creates an assembly for each page - default.aspx.dll. However, this is only marginally more useful to you as you still need to know the name of the control or page you are looking for when you are loading - so you have to ensure your types and naming is consistent. It should, however, respect the name of the classes in app_code so this may work for you.
One other thing you could do is move all of the code in app_code out into it's own assembly, and then add that as a project reference. That would also simplify this problem.
Lastly, you could enumerate all of the dll's in the bin directory, and search each one for the type you are looking for. As this is fairly expensive, do it once, and cache the result somewhere so you don't keep doing it everytime you look that type up. This is probably the worst solution.
This is trivial to do in a WebApplication project, but I assume you are stuck with the WebSite one?
EDIT: As an update for the comments; if I use the Publish Web Tool, then all of the code in app_code goes in the bin directory in a dll called App_Code.dll - this behaviour does not change even if I use fixed naming (all fixed naming effects the naming of the dll's for each page, usercontrol). If I use ILSpy on this file, I can see my classes in there. So I know the name of the assembly, and it's location - I should be able to get at the types in it with minimal effort. I wonder why I'm seeing different behavior to you!
I created a simple class called "Person" with an Id and Name, put it in App_Code, compiled the site, and then ran the following code:
Type myType = Assembly.LoadFrom(Server.MapPath("~/bin/App_Code.dll")).GetType("Person", true);
Response.Write(myType.ToString());
It wrote out "Person", as expected.
Further Edit
The penny drops! If I then do:
object myObject= Activator.CreateInstance("App_Code.dll", "Person");
And try to cast myObject to person, I get the following message:
The type 'Person' exists in both 'App_Code.dll' and 'App_Code.jydjsaaa.dll'
So it's time to be devious.
in Global.asax, on Application_OnStart, do the following:
Application["App_Code_Assembly"] = Assembly.GetAssembly(typeof(Person));
In my test default page, I then did:
Assembly app_Code = Application["App_Code_Assembly"] as Assembly;
Response.Write(app_Code.FullName);
Which gave me the randomly named app_code it is actually running with in Temporary ASP.Net Files.
This is why I hate Web Site Projects ;-)
I have a couple of web applications whose source code is missing. The project is compiled to a dll and is hosted on a IIS.
I have couple of questions to make.
What is the best way to recreate the
project from the dll file??
We are planning to change the
database server, and the database
connection strings are specified in
the Global.asax ( I mean the public
class Global : HttpApplication ). Is
there a way I can subclass this
Global and override the connection
strings? If yes, how can I make the
IIS refer to the new dll
Thank you all for any suggestions!!
For first part, use decompiler tools such as Reflector/ILSpy/dotPeek to convert IL code from DLL to higher level language such as C#. However, tools cannot get back comments, local variable names and project structure. You need to manually organize the code into files and project structures. From aspx files, you have to figure out the code-behind classes and then link up the source of the class into a correct named code-behind file - for example, if default.aspx says that it inherits from MyApp.Default then create file default.aspx.xs and put the source code for the class into that.
For second part, you can create a new class derived from Global and modify Global.asax to use that class - you need to put the assembly containing new class in bin folder and overwrite inherits clause in asax file to point to the type name of new class. You anyway need to inspect the code of your current Global class (using tools sighted above) to see if you can override connection strings by sub-classing.
Probably the best tool available to reverse engineer a dll into code is .NET Reflector. Unfortunately, the latest version is no longer free, but it is worth the money.
I am not sure exactly if this still applies if you can already reverse engineer your source code. However, I would recommend moving your connection strings outside of your project into web.config as a best practice. This way you can make the change in the future without changing any code.
I have a web project called "TestResourceApp" with Labels.resx in App_GlobalResources folder. I want to add another language by creating a satellite assembly.
Here are the steps I took to create the satellite assembly. The default text always get displayed. What did I do wrong ?
1) Create Labels.fr.resx in a different folder.
2) Generate resource file:
Resgen Labels.fr.resx TestResourceApp.App_GlobalResources.Labels.fr.resources
3) Generate satellite assembly:
AL /t:lib /embed:TestResourceApp.App_GlobalResources.Labels.fr.resources /out:french.dll /c:fr
4) Copy french.dll to TestResourceApp/bin/fr
I have uiculture set to auto in web.config and I have change the language on the browser.
I was able to use this page to solve some satellite assembly issues I was having. I'll throw in a few more things to check.
It's helpful to decompile the "neutral" assembly and see how it's put together. A tool like ILDASM.exe is helpful for this purpose. Once you get it decompiled, look through the text output for ".mresource", and you should see one with your naming. For example, if you add a resource to a Visual Studio project, they're named MyAssemblyName + ".Properties.Resources" + a language (if any) + ".resources" Examples:
MyAssembly.Properties.Resources.resources (neutral language)
MyAssembly.Properties.Resources.en-US.resources (English (US))
In my case, I had the file named properly, and in the appropriate folder (such as Bin\en-US). I was able to verify that much by using ProcMon.exe (by the SysInternals guys) and could see the worker process finding and reading in my DLL file (instead of just saying "PATH NOT FOUND"). However, it was not finding the resource by the name that it expected it to. That's when some disassembly helped to get to the bottom of the naming problem.
So, use ProcMon.exe to narrow down the kind of problem you might have. Hopefully that's helpful to someone.
It's complicated but here are a few tips for those who run into this problem:
Try to include the resx in the web project and let VS do the job for you.
Reflector is your friend. Compare satellite assemblies you created and those created by VS.
If you web app is targetting ASP.NET 2.0, you should use Resgex and AL that come with .net 2.0. Open the assemblies in Reflector and check the "references". It should reference mscorlib version 2.0.
If you deploy your web app using web deployment project, make sure the namespace for the resources in your satellite assemblies is correct. Again, compare with what VS creates. In my case, I used the wrong tool to generate the designer.cs file because I wanted them to be accessible from a different assembly. Make sure you are using GlobalResourceProxyGenerator. Otherwise, the namespaces won't match and the deployment code will not be able to find your resource. The namespace in the designer.cs should simply be "Resources", not "XXXX.App_GlobalResources"
Did you have set enableClientBasedCulture to true in globalization ?
I'm using selenium to run some functional tests on the UI for our current application.
I want to ensure that strings from the resource files in the Web project are being displayed at the correct time and place.
Simple (I thought) all I have to do is reference the assembly of the web application and assert that the text selenium is reading from the UI matches the test in the approriate resource file.
The problem is the ASP.Net does some precomilation processing on the resource files and compiles them into an assembly called App_GlobalResources, which isn't created by the normal build process so the functional tests fail because that can't find the App_GlobalResources assembly to look the string up from.
So, any suggestions? Do I need to abandon the App_GlobalResources approach and do something manual that I have control over?
Do you understand the problem or do I need to provide more info?
My interim solution is to use SVN:Externals to pull a copy of the resx files into the test project.
I can then access them via
ResourceManager resource = new System.Resources.ResourceManager("My.Web.Namespace.resources.ImageUrls", Assembly.GetExecutingAssembly());
Its ugly because I already have a reference to the webproject (which I can probably remove now...) and I don't like mixing source files between projects. It just feels like asking for trouble but until someone suggests something better this will have to do.
Have you considered moving your GlobalResources into a separate assembly and then referencing that from both your web project and your test project? This is quite easy to do in VS 2008, and achievable but a little more difficult in VS 2005.
I was able to solve a similar problem using that approach.
