Hello,

Thank you for your support. I works directly with: Dim endpoint As UAEndpointDescriptor = New UAEndpointDescriptor(OPCServer).WithUserNameIdentity(UserName, Password)

Hello,

one such example is here: opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...nregister%20all%20clients.html

And you can put a backslash into the user name and will stay there. Just do not try to get it back from UAEndpointDescriptor.UserName, because that is a different thing.

If you really want to check that the the backslash "stays" there, you need to check UAEndpointDescriptor.UserIdentity.UserNameTokenInfo.UserName.

Best regards

These lines should be removed (they are not doing any harm, but they terribly confuse you, because you then tend to inspect the result and complain about the removed backslash):
endpoint.UserName = UserName
endpoint.Password = Password

Hello,

I am sorry but I don't follow you. I attach all my code:

Dim UserName As String = "user1"
Dim Password As String = "pass1"

If EasyUAClient Is Nothing Then InitUA()

Dim HandleID As Integer = 0
Dim item As OpcLabs.EasyOpc.UA.OperationModel.EasyUAMonitoredItemArguments
Value = Nothing

If (String.IsNullOrEmpty(UserName)) Then
item = New OpcLabs.EasyOpc.UA.OperationModel.EasyUAMonitoredItemArguments(OPCServer & OPCTag, OPCServer, OPCTag, New UAMonitoringParameters(Optional_OPCRequestedUpdateRate))
Else
Dim endpoint As UAEndpointDescriptor = New UAEndpointDescriptor(OPCServer).WithUserNameIdentity(UserName, Password)
endpoint.UserName = UserName
endpoint.Password = Password

item = New OpcLabs.EasyOpc.UA.OperationModel.EasyUAMonitoredItemArguments(OPCServer & OPCTag, OPCServer, OPCTag, New UAMonitoringParameters(Optional_OPCRequestedUpdateRate))
item.EndpointDescriptor = endpoint
End If
HandleID = EasyUAClient.SubscribeMonitoredItem(item)
Return HandleID

They line in bold should be changed you mean?

Thank you in advance.

What you wrote makes no sense. You "cannot get the same result" if you use just WithUserNameIdentity, because your code is then printing out UAEndpointDescriptor.UserName and UAEndpointDescriptor.Password, which, I repeat, should not be used.

Hello,

The code is done by vb.net.

If I use the following expresion:

UAEndpointDescriptorExtension.WithUserNameIdentity(New OpcLabs.EasyOpc.UA.UAEndpointDescriptor(OPCServer), UserName, Password)

I receive the same result.

Which function should I use in orden to identify?

The code work properly if there is not a backslash in the UserName.

Best Regards,

I am confused. First question, which language or tool is this code in?

More:

You seem to be mixing two things, although the code seem to be incomplete. The WithUserNameIdentity extension method would be the right approach.
Setting UserName and Password directly on UAEndpointDescriptor is *not* the right approach, so trying to resolve why it behaves the way it behaves with the backslash is pointless. So you can just leave out these parts.

Best regards

Hello,

We use the following code:

Dim uAEndpointDescriptor As OpcLabs.EasyOpc.UA.UAEndpointDescriptor = UAEndpointDescriptorExtension.WithUserNameIdentity(New OpcLabs.EasyOpc.UA.UAEndpointDescriptor(OPCServer), UserName, Password)
uAEndpointDescriptor.set_UserName(UserName)
uAEndpointDescriptor.set_Password(Password)
LogTXT(String.Format("+++++++++ endpoint.UserName: {0} - endpoint.Password: {1} - endpoint.Port: {2}", uAEndpointDescriptor.get_UserName(), uAEndpointDescriptor.get_Password(), uAEndpointDescriptor.get_Port()), False, "")


IF We use the following user and password

USER: name\user
Password: 1234

We get the following data:
+++++++++ endpoint.UserName: - endpoint.Password: 1234 - endpoint.Port: -1

IF We use the following user and password

USER: nameanduser
Password: 1234

We get the following data:
+++++++++ endpoint.UserName: nameanduser - endpoint.Password: 1234 - endpoint.Port: 65300
