Visual Studio 2010 C# And Classes In App_Code Folder?
Jan 7, 2011
I've searched but not found much that helps, could be using wrong search terms.Anyway, currently using Visual Studio 2005 and VB, but just got Visual Studio 2010 and trying to use C# and am having problems using classes, I think I'm missing something simple here.
In both 2005 & 2010 I create a new website and a Default.aspx, in 2005 using VB, C# in 2010.
Right-click the project -> Add New Item -> Class, and leave it as Class1.vb/Class1.cs
Both 2005 & 2010 prompt to place it in the App_Code folder, so choose yes.
Here are the class files, I've not changed anything apart from create a very simple function:
Class1.vb code: [Code]....
Class1.cs code: [Code]....
In my VB project Default.aspx.vb: [Code]....
No errors, and debugging shows that a = "hello"
My Default.aspx.cs: [Code]....
This gives an error:Error 1 The name 'tester' does not exist in the current context D:Visual Studio 2010WebSite11Default.aspx.cs
How do I reference the tester function within Class1 in my C# project?
at vs2008 i could set App_Code folder, but at vs2010 i can not do it, that's why i put my dataset's and class' to App_Data folder. Either I do not know even App_Data folder is secure?
I am fairly new to ASP.net and web page development. I normally create Windows Apps, but the move is on to web pages. I have read and tried a number of posts on this matter, but none of them resolved the problem I am having. I have created a web site (I'm positive it is a web site) and added a class. Visual Studio automatically created and added the class to the App_Code folder. Accordingly, I added the get/set methods to the class and made them public. When ever I try to access the class from a code behind for any page, I get the class name, but nothing more. Intellisense shows only Equals and EqualsReference - no variables. I'm used to using classes in windows forms application and this would make life so much easier if it worked like it is supposed to work.
I am a developer who up until now only used WAP assemblies. Is that old and outdated nowadays? For example I have found a really great sample of google map API I'l like to use but my project is in VB.NET and the sample is using code in App_Code folder in C# so I cannot mix and integrate in a easy way. Do I have to convert the C# code into VB.Net to make it work or is there a shortcut when finding sample code in App_Code folder in the wrong code language?
My problem is that the intellisense is not enabled within the App_Code folder, so to twick this problem I initially create a separate folder where I develop my classes then I move them to the App_Code but, but I'm convinced that this is not the right practice so how to configure visual studio 2008 to enable intellisense at the App_Code folder
Best way to describe my issue with vs 2010.create a new website. create the App_Code folder. create a new class in the folder. put the line "x" in the class declaration. hit compile. And the website will compile with no errors. It's not "seeing" this new class as being part of the project best I can tell.
Using vb.net/asp.net 2005. I have a project that is done with all vb.net, however I want to get some more experience with C#.Net. I am considering creating a new database class to put in the app_code folder.
I have an application which contains different modules from different databases, for instance, I have a table called "ITEMS" in each database. When I create the classes for the table ITEMS I wonder how I can differentiate among them.
For instance, for now, I have "ItemDetails.cs" under App_Code folder BUT I need to create another "ItemDetails.cs" class which will reference the table ITEMS from a different database. If I create folder under the App_code the class name still remains the same.
I could add an acronym in front the class to differentiate which database I am working from but that makes the class name too long.
How can I prevent Visual Studio from naming the classes for new pages that are in folders from being named with the folder name? Does this method not set "right" with anyone else?
I'm using VS 2010. I got the references to the classes from my project, now I need the .dll files but I can't seem to find them. How do you add the .dll's?
I have a single project. and I have two folder in it. In the 1st folder I have a class named Class1 and in the 2nd folder I have a class named Class2. Can anyone tell me how I can access members of Class1 in Class2. I have tried by adding namespace in Class1 and Using that namespace in Class2. But it is giving error. It is easy to access classes or their members from App_Code folder. I don't want to put my classes in app_code folder.
I have existing ASP.NET 3.5 project I migrated to Visual Studio 2010. I didn't migrate it to .NET 4.0. Every time I try to edit .aspx page, it alters the .designer.cs class to point to System.Web.UI.WebControls.WebParts.UpdatePanel class instead of
System.Web.UI.UpdatePanel
class and then the build of course produces an error. The project properties says ".NET3.5".Also the "design" tab produces just one box saying "unknown server tag asp:UpdatePanel". It seems like it is looking at .NET4.0 to generate the desgn view, not 3.5
I was trying to create a Dynamic Data Website using VS 2010 RC. An attempt to create an App_Code folder where I would put a LINQ to SQL class, failed. When I selected 'Add ASP.NET Folder' to add the folder, I had options to create only the following folders:
I have a simple web app project in Visual Studio 2010 (converted from 2008 project). For some reason when I publish the app, Visual Studio doesn't copy the App_Theme -folder to the publish destination folder. This will cause the app to fail when deployed to production environment.
App_Theme is considered as "system" folder by VS (shown as grey), which means that I can't manually set it's publish properties.
how to get VS to copy App_Theme -folder when deploying?
I am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?
I tried to install Visual Studio Prof 2010 trail version in my system, but i got an error saying 'Please remove/uninstall Visual Studio 2010 load test controller' to proceed installation. i uninstalled my previous VS2008 software from system and i could not find anything like 'Remove/Uninstall Visual Studio 2010 load test controller' software in my Add/Remove Programs.
I have a 'Connection.cs' file in the App_Code folder of Microsoft Visual Web Developer 2010, but it alerts me of an error:
The type or namespace name 'Connection' could not be found (are you missing a using directive or an assembly reference?) ('Connection' is the name of a class in the Connection.cs file)
So, i am running SQL Server 2008 R2 Express and VWD 2010 Express on Windows 7. I am logged in as admin on my machine. I have created a new web app project (VB Linq to SQL) and I have attempted to add an existing .mdf to my project's App_Data folder. I right-click, choose "add existing...", navigate to the .mdf file in the C:Program FilesMicrosoft SQL ServerMSSQL10.SQLEXPRESSMSSQLDATA folder, and then i get an "Access is denied" error box with no further details.
I am using visual studio 2008 professional. I created a unit test project for my current website (project). This unit testing project is mainly testing code in App-Code folder. In order to be able to access classes from App_Class I need to add App_Code.dll reference to my unit testing project. Right now, I am doing like: publish website, which produce App_Code.dll. Then I added it to my unit testing project. This is very time consuming process: if I make any changes on under test class, I need to publish website to get App_Code.dll. It takes at lest 4 minutes to publish and get App-code.dll. If I have add the new App-code to my unit testing project, it takes about 1 to 2 minites. Is there an easier way toget App_Code.dll?
I have tried use Accessor that MS Test autogenerated, which deos not need App_Code.dll, however, I cannot get an object instantiated. So that is why I add App_Code.dll to my test project.
Even though I when I create a linqtosql class I mark C# as the language it was always shows up as a Visual Basic file in the App Code file. I can't get it to stop doing that. ????? What is going on?
I have been ising TFS 2010 with VS 2010 Ultimately for a couple of months now. I have a client who is using Visual Web 2010, does anyone know if this integrated with TFS easily?
I just recently upgrade my asp.net web project from visual studio 2005 to visual studio 2010. The upgrade was successful with no problems however im missing some features with this project. The One Click Publish feature(which is greyed out) in the header area of Visual Studio 2010 and the Add Config Transforms feature which is no where to be seen when you right click on web.config. When i create a new web project straight from visual studio 2010, these options work fine.
