I'm doing a C # application where I've created a database for the login system where I have created users. In this login system I wanted to add permissions to certain users. For example, the program detects that it is the admin to log in and enables a certain button, while another user is disabled.
Is this possible? And how?
You can create a field in the table to know the type of user and / or hierarchy to know 'how will' validate who will have rights to the components of each module.
The example below is just a base since I do not know how your table is mounted. But initially this is how you can start thinking about your doubt.
private void btnLogin_Click(object sender, EventArgs e)
{
try
{
Usuario objUsuario = new Usuario();
if (objUsuario.ConsultarUsuario(txtLogin.Text, txtSenha.Text) > 0)
{
if (objUsuario.ChecarAcessoUsuario("opcCaixa", "", Metodos.codUsuario, Metodos.codGrupo))
{
this.Close();
}
else
{
MessageBox.Show("Usuário não possui acesso ao caixa loja!", "Mensagem", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
else
{
MessageBox.Show("Login ou senha inválidos!","Mensagem", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
catch (Exception ex)
{
throw ex;
}
}
public bool ChecarAcessoUsuario(string menu, string acao, int usuario, string grupo)
{
try
{
var segnivel = ConsultarSegnivel1(menu);
if (!string.IsNullOrEmpty(segnivel) && ConsultarDireitos(segnivel, usuario, grupo))
{
return true;
}
segnivel = ConsultarSegnivel2(menu);
if (!string.IsNullOrEmpty(segnivel) && ConsultarDireitos(segnivel, usuario, grupo))
{
return true;
}
return false;
}
catch (SqlException ex)
{
throw ex;
}
catch (Exception ex)
{
throw ex;
}
}
