Estou estudando Modificadores de acesso em Vb.net e me surgiu uma dúvida em Protected Friend
Segundo o site macoratti.net:
Protected: esconde os membros de uma classe e “os membros marcados com o modificador Protected podem ser acessados na mesma classe e em todas as classes que herdam da classe.”
Friend: “você quer que todas as classes do seu projeto sejam capazes de acessar os membros da sua classe mas que classes externas ao seu projeto não tenham este direito.
Neste cenário nem o modificador
Private nem o
Protected podem lhe ajudar, para esta situação temos o modificador
Assim sendo, tenho dois projetos em uma mesma solução,
Proj1, tenho a classe Aluno:
Public Class Aluno Public Nome As String Protected Endereco As AlunoEndereco Protected Friend idade As Integer Protected Class AlunoEndereco Public Rua As String Public Cidade As String Public Estado As String Public Cep As String End Class End Class
Proj2 tenho a classe Teste que herda de Aluno:
Class Teste Inherits Aluno Sub New() idade = 2 End Sub End Class
Como um modificador de acesso
Protected permite um membro só ser visível na própria classe e em classes herdadas, mas ao combinar com o modificador
friend, pensei que aconteceria que o campo idade só pudesse ser visto dentro da classe em
Proj1 mas não em
Proj2, mas aconteceu que também foi possível acessar idade a partir da classe Teste em
Proj2, alguém poderia me explicar por que isto acontece?
The thread titled
"<the subject>" started normally and numbered nine messages, when something strange began to happen: the replies of my friend get titled
"Re: <the subject>" and end up each in a new thread of its own in GMail. The conversation view is still on. What could cause this and how do I cause all these separate threads and the future replies to be joined with the original thread?

He has a fresh copy of ubuntu, no Synaptics package manager, just ubuntu the basic configuration. He can’t access the internet only through his phone. He has wireless, but the wireless adapter failed to install. I tried going to /pool/main/dkms/ and install it manually but fails due to missing dependencies. I just want to bundle my packages and add it to his google drive so he can download them and install them. I know it’s a pain. I’d really appreciate your help.
My friend (Indian) is in another country and he had to tear last page of his passport because that page captured some water droplets and if he wouldn’t have teared it would had affected other pages as well. I suggest him to visit Indian embassy in that country and talk to them.
What do you think its fine to his passport would be considered damaged and he needs to get it fixed? How much time it take to get new passport in a different country?

This question already has an answer here:
- Driving Someone Else's Car Across US/Canada Borders 1 answer
I am a Swiss citizen living in Vancouver, BC, Canada as a temporary resident (student visa). I am planning a small trip toward the USA and a friend of mine offered me to use her car for this trip. This friend is American (living in Vancouver, BC, Canada) and her car has an American license plate (insured with Liberty Mutual).
Someone told me that, as a non-Canadian, non-American, I might have a hard time crossing the border with a car with US plates. Should I be worried of being rejected at the border? Do I need to prepare some specific documents? Would it help if my name was added on the insurance contract (I don’t know if this is possible). My son (7 weeks old) is Canadian. Does it make any difference if he is in the car?
I’m traveling alone by Egyptair from Nigeria to Russia.The ticket was bought by my friend and by his DEBIT CARD. After I printed out the ticket, I saw in the rules that CREDIT CARD holder must be one of the travellers. And the company can remove the passenger from the flight if he does not show a card which tickets were paid for. Does it work with DEBIT CARD too? Should I worry about this?
And another problem is that my friend mixed up my first and last name when he booked a ticket. I know this is not so critical, but in this situation can it also affect. My friend says everything will be fine, but I’m not sure.
I want to go on a two-weeks holiday.
My company will sponsor me. They have made a hotel reservation for me, but I have a friend in the UK, who has agreed to show me around the country on my arrival.
Please note that he didn’t have any hand in sponsoring my trip. My question is do I still need to including his documents in my supporting documents?
