c - How to create a program that reads the last commands exit status? -


In Linux C, how can you read the exit status from the last programs

For example: 

  true; $ Echo?

Will show 0 for success. But I want to replace it with a C program: 

  true; ./echo_exit_status

How / where the final exit code is $? Is C program available?

The exit command is not accessible for the last command executed later In the program (absent horrifying hacking - associated with parent shell with debugger or somatoscope).

You can write a shell function or a helper that exports this value to the environment - but no solution is possible for which the shell's involvement is not required.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
