around this issue The main question is: how can i make InputBox keep poping up when the user either clicks Ok or presses [Enter] on the keyboard? This program stores each value in a sequential access file. , Try initializing outfile in the declaration:
code :
Private Sub btnSave_Click(sender As Object, e As EventArgs) Handles btnSave.Click
    Using outFile As New IO.StreamWriter("Scores.txt")
        Dim strInput As String
        Dim dblInput As Double

        strInput = InputBox("Enter A Number(done when finished)", "Test Scores Project")
        If Double.TryParse(strInput, dblInput) Then                
        End If
        While strInput <> "done"

    End Using

End Sub

this will help you are looking to bind the Enter key (called "" by tkinter):
code :
self.Combobox_Length_Right.bind("<Return>",self. update_length)
self.Combobox_Length_Right.bind("<Return>",self. update_length)

wish of those help For interactive program, where you need more control over the input, consider using fgets to read lines, and sscanf to parse. This will let the code decide when the 'flush' remaining characters on the line
code :
    char buff[200] ;
    if ( !fgets(buff, sizeof(buff), stdin) ) {
        // Error
    } ;
    char foo ;
    sscanf(buff, "%c", &foo) ;

    // next fgets (and getchar) will force reading a line!

Any of those help If inputting numbers is mandatory, just don't give the user option to do it wrong. One option would be to move the case 1 code into a getnumbers function and do something like;

hop of those help? In UNIX, to control when data is returned from a terminal device you use tcsetattr()/tcgetattr() functions to change the characteristics of the terminal device. Apparently these functions are POSIX.2001 too.
Here is a simple C program that will do what you want, by setting the terminal device to return characters to the reader one character at a time (see inline comments, robust error checking not included):
