问题 I'm working on creating an installer that has several applications that can be optionally installed. I'd like to write my installer script so that I don't need to update it every time I add a new application to my apps directory. Is this possible with NSIS? I've got code to search through a folder for sub folders and extract their names, but am having trouble using that to make components in the installer. Folder Structure -Install_Directory -Main_Application -Applications -App_A -App_B -App

问题 I'm implementing an architecture when i have a container of heterogeneous objects which may have or not some common methods-attribute. I need to cycle through them and apply some functions, update some members, and call some methods over the various interfaces. I've come up to what i believe a "standard" architecture, based on inheritance: #include <vector> #include <memory> #include <iostream> using namespace std; struct Base { virtual ~Base() {} }; struct PositionInterface { int x = 0; int

问题 I am currently having a problem with JFrame and Images. This program uses an Applet then adds it to a JFrame in a different class, so it can be ran as either an Applet or an Application. Currently, the frame holds only a handful of images, and no components. I recently attempted to add a JTextField using absolute positioning (LayoutManger is null) and it works fine, except all the images are removed, leaving me with just a JTextField. Why is this happening? How can I fix it? My code is posted

问题 I have to write an android client, in which i should use HttpComponents to connect to a specific Server on Port 8080. For now, all i've found, was the Examplecode from the Apache-site, which is nearly perfect for what i need, except the Port it connects to: if (isSet) { throw new IOException("Hostname or Port are not set!"); } HttpClient httpclient = new DefaultHttpClient(); HttpGet httpget = new HttpGet(serverURL + ":" + serverPort + "/maps"); HttpResponse response = httpclient.execute

For example I love the forms / validation and ACL elements but am not sure if that is actually possible without the whole MVC system? As a framework ZF2 is very slow (although I think its a very good system) so would like to encourage its use without the whole package. Thanks. 回答1: Yes. Zend Form component has a separate repository and it can be used in any application as a component with help of composer

问题 I'm a beginner in C++ and I started learning how to use QT components through code at MVS IDE. I still don't know if that was the best option to begin, but since I'm a java programmer, I made the path I made with Java (Swing components). So, my problem is, how to comunicate two class of my code, since in one I made the window frame and in the other I made my menu bar? In java I would make something like: JFrame frame = new JFrame(); JMenu menu = new JMenu(); frame.add(menu); Anyway, This is
