public

问题 Assume I first defined a type A in which a public procedure f is defined, and may also be bonded to A. In another module I have this type extended into B. However, when I use type B, I do not want f to be exposed. By the way, I don't want to use the submod technique. complement: Assume type(A) is already defined: module mA type::A ... contains procedure::f endtype endmodule In another module B, we extend A as: module mB use mA type,extends(A)::B ... endtype endmodule In this module, f may

问题 I'm having problems with this SearchButton code in VB (Visual Studio 2012): This code in Form1.VB: Private Sub SearchButton_Click(sender As Object, e As EventArgs) Handles SearchButton.Click Dim results As Artist results = Array.SearchArray(artistArray(), SearchTextBox.Text) End Sub and I'm getting an error that artistArray is inaccessible due to its protection level.

When I try to hit it using my internet ip or from any other machine, inside or outside of my network, it just times out. I'm on Mac OS 10.9.1, ruby 1.9.3, rails 4.0.0. I've done a lot of searching but all I can find is problems where people didn't forward their ports or bind the right ip. Here are the areas I've investigated: Ports - I've tried

问题 I have multiple arrays whose sizes need to be determined by the user input. These arrays should be accessible in the main method as well as the stepTwo() method. However, I am stuck. The user input doesn't come until the main method, but if I declare the arrays in the main method, then I can't access the arrays in the stepTwo() method. I would prefer not to pass the arrays as parameters to stepTwo() as I tried that before but came up with multiple errors. Any suggestions? See below for
