error-code

问题 When trying to run my application on the emulator I get an error from the activitymanager: ActivityManager: Error type 3 My activity exists, is listed in the manifest (in fact, its the MAIN launcher activity).

问题 I have a function that returns an id number if the argument exists in the database. If not, it returns null. Is this begging for a null pointer exception? Negative id numbers are not permitted, but I thought it would be clearer to have non-existent arguments returning null instead of an error code like -1. What do you think? private Integer tidOfTerm(String name) throws SQLException { String sql = "SELECT tid FROM term_data WHERE name = ?"; PreparedStatement prep = conn.prepareStatement(sql);

I'm getting the following error: c2227 left of '->Init' must point to class/struct/union/generic type c2227 left of '->Init' must point to class/struct/union/generic type And this is my code: MainGame.h #pragma once #include <SDL/SDL.h> #include <GL/glew.h> #include <vector> #include "GLTexture.h" #include "GLSLProgram.h" #include

问题 I want to create a grunt file that runs 3 grunt tasks serially one after another regardless of whether they fail or pass. If one of the grunts task fails, I want to return the last error code. I tried: grunt.task.run('task1', 'task2', 'task3'); with the --force option when running. The problem with this is that when --force is specified it returns errorcode 0 regardless of errors. Thanks 回答1: Use grunt.util.spawn : http://gruntjs.com/api/grunt.util#grunt.util.spawn grunt.registerTask('serial'

问题 I have created a simple hook for a Liferay site I have. It contains a 404.jsp that overrides the default Liferay 404. It works fine if I type in a specific page. For example: Going to http://localhost:8080/jooky.jsp throws SEVERE: PWC6117: File "C%3A%5Cbundles%5Cliferay-portal-6.1.0-ce-ga1%5Cglassfish-3.1.1%5Cdomains%5Cdomain1%5Capplications%5Cliferay-portal%5Cjooky.jsp" not found in my Glassfish server log and redirects me to my custom /errors/404.jsp without a problem. However, going to
