Whose "popup"?
You'll need a separate NAMESPACE for each DUPLICATE CLASS NAME.
Then you can "code logic" for YOUR "popup" or whatever.
And in your CODE, you qualify with a NAMESPACE that VS can resolve with (Intellisense-wise).
There is no other magic; it's all in the head.
YOU are the only "customer" at this stage.
Beyond that, you use "Interfaces".

Well that was an interesting discussion which seems to have shown that you need to redesign your data structure to meet your requirements. The entire issue revolves around the string of skills which you are storing incorrectly (as a number of respondents have pointed out).
This should be seen as a valuable lesson (hopefully others will also benefit). Do not be discouraged by any negative responses, this was a good discussion with some interesting information generated.

You can't have multiple classes with the same name, unless they're in different name spaces.
This won't work:
namespace One
{
public class ABC {}
public class ABC {}
}
but this will (as long as you fully qualify all instantiations):
namespace One
{
public class ABC {}
}
namespace Two
{
public class ABC {}
}
You could use inheritance, but your class names would still have to be unique.

Pardon me if this was already mentioned, this is a fairly long thread. But I have a feeling that this case is handled by namespaces for a couple of decades. I mean you can have a POCO for your needs in one namespace and another class for what customers want in the other namespace. And you can map one to another manually or via some tool like Automapper.

Also, I have a feeling that you're confusing language and tooling. Is popup some sort of language construct or a feature in IDE? Which one? VS? VS code? Jetbrains rider?

Hi,
Not sure which forum I need to use for this issue. Currently we are using visual studio 2012 ,Community edition ,net framework 4.0. On our workstations, we installed Visual Studio Enterprise 2019 version. We Should migrate our project to.net framework 4.7.2 in VS2019. When I open project in VS 2019 with .net framework 4.7.2, it is giving the run time error as Authentication error (Project was successfully build without any error). Where the same project worked good on VS2012.
It is showing
"
Exception Details: System.UnauthorizedAccessException: Windows Integrated Security is not enabled
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true">, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in File Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

Where i have enabled windows integrated security .
windows authentication as enables and anonymous authentication as disabled.
Can anyone please help me what changes i need to make over here?

That's an error being thrown by your code, not the framework. Look at the preceeding lines in that method to see why you're reaching that exception.

When the same code was executed in VS2012 it worked without any error and authentication was true
"void Application_AuthenticateRequest(Object sender, EventArgs e)
{
if (Context.Request.IsAuthenticated)
{
Context.User = UserPrincipal.Authenticate(Context.User.Identity as
System.Security.Principal.WindowsIdentity);
Thread.CurrentThread.Name = UserPrincipal.CurrentUser.LoginName;
}
else
{
throw new UnauthorizedAccessException("Windows Integrated Security is not enabled");
}
}
"
The above method is where i'm facing issue. In VS2019 the IsAuthenticated is returning false where it returned true in VS2012 and worked fine.

Then you either haven't enabled Windows Authentication, or you haven't disabled Anonymous Authentication.
Check your settings in web.config - you should have both:
<system.web>
<authentication mode="Windows" />
<authorization>
<deny users="?" />
</authorization>
</system.web> and:
<system.webServer>
<security>
<authentication>
<windowsAuthentication enabled="true" />
<basicAuthentication enabled="true" />
<anonymousAuthentication enabled="false" />
</authentication>
</security>
</system.webServer> NB: You may need to "unlock" the authentication section to be able to configure it. In IIS Manager, it's under "Feature Delegation". If you're using IIS Express, you'll need to edit the applicationhost.config file in the .vs\config hidden folder.

The error message is pretty clear that you haven't "unlocked" the authentication sections.
It looks like you're using IIS Express, so you'll have to edit the applicationhost.config file in the hidden .vs\Project_Name\config folder within your solution.
Open the file in a text editor and search for the following lines:
<section name="anonymousAuthentication" overrideModeDefault="Deny" />
<section name="basicAuthentication" overrideModeDefault="Deny" />
<section name="windowsAuthentication" overrideModeDefault="Deny" /> On each line, change "Deny" to "Allow". Save the changes and try running your project again.

I had set that to Allow in C:\Windows\System32\inetsrv\Config\applicationHost.config

Still i'm getting the same Error(I'm using windows 10(FYI)).

You are using IIS Express. You need to edit the applicationHost.config file in your solution folder.
There's a hidden folder called .vs within your solution folder. Inside that will be a folder with the same name as your project. Within that will be a folder called config. The applicationHost.config file you need to edit is in there.

Thanks a lot. It worked.For the Authentication snippet which i tested.
But in my project the isAuthenticated is returning "false" ,i thought my project had the same as snippet code issue but here even after configuring everything showing error and authentication is failing. Should we add our name somewhere so that isAuthenticated returns "TRUE"

If Windows authentication is enabled, and anonymous authentication is disabled and anonymous users blocked, then unauthenticated requests shouldn't be able to reach your application. There must be something else going on.

okay
Will there be any file related to "windows integrated security" to be enabled as Project specific like applicationHost.config
|
|
|
|

If you've unlocked it in applicationHost.config and enabled it in web.config - making sure to disable anonymous authentication as well - then it should just work.

Yes did that. Yet Context.Request.IsAuthenticated is returning false even after the changes in applicationHost.config of the project
|
|
|
|
|
There there's something else going on that I can't see. I've done this dozens of times; with the changes to applicationHost.config and web.config, it just works.

Hi,
i'm trying to print to an epson esc/pos printer using vb.net.
trying opening the serial post (the name is correct, i can see it dubuging) the execution goes in exception whith the error "Il nome specificato non inizia con COM/com o non si risolve in una porta seriale valida.Nome parametro: portName ParamName=portName"
This is my configuration code:
ADRPort = New System.IO.Ports.SerialPort(GLOBAL_DisplayCOMTkt, _
19200, _
Parity.None, _
8, _
StopBits.One)
...
...
...
...
If (ADRPort.IsOpen) Then
ADRPort.Close()
End If
If Not ADRPort.IsOpen Then
ADRPort.PortName = GLOBAL_DisplayCOMTkt
ADRPort.DtrEnable = False
ADRPort.RtsEnable = False
ADRPort.BaudRate = 19200
ADRPort.DataBits = 8
ADRPort.Parity = Parity.None
ADRPort.StopBits = StopBits.One
ADRPort.Handshake = Handshake.None
ADRPort.ReadTimeout = 2000
ADRPort.Open()
End If
Thanks for any support you can supply....

The error message is pretty explicit: "Invalid port name"
Quote: The specified name does not begin with COM / com or does not resolve to a valid serial port. Parameter name: portName ParamName = portName "
So use the debugger, and look at exactly what you are setting the PortName property to: GLOBAL_DisplayCOMTkt has a value, but we have no idea what it is - and we can't do that for you!

I have code in my DAL that I want to call from the UI asynchronously in my WPF app. I think I have this right, but I'd like to get your opinion.
DAL Interface
public interface IDAL
{
Task<List<ReportData>> GetReportData(ReportArgsEntity args);
}
DAL
public class MyDAL : IDAL
{
public Task<List<ReportData>> GetReportData(ReportArgsEntity args)
{
var t = Task.Factory.StartNew(() =>
{
List<ReportData> results = new List<ReportData>();
return results;
});
return t;
}
}
BL Interface
public interface IBL
{
Task<List<ReportData>> GetReportData(ReportArgsEntity args);
}
BL
public class MyBL : IBL
{
IDAL _dal;
public MyBL()
{
_dal = new MyDAL();
}
public Task<List<ReportData>> GetReportData(ReportArgsEntity args)
{
return _dal.GetReportData(args);
}
}
View Model
public class MyViewModel
{
IBL _bizLayer;
public MyViewModel()
{
_bizLayer = new MyBL();
}
private async void RunReport()
{
var args = new ReportArgsEntity()
{
};
var reportData = await _bizLayer.GetReportData(args);
}
}
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
