Working Code in iOS 7 and 8 if ([self checkOSVersion] >= 7) { Class LSApplicationWorkspace_class = objc_getClass("LSApplicationWorkspace"); NSObject* workspace = [LSApplicationWorkspace

问题 In Excel 2003 I'm getting a Runtime error 1004: "application-defined or object-defined error" on the last line of this code (commandtext = abc) Sub SCommandTxt() Dim abc as string abc = Sheets("Totals").PivotTables("PivotTable2").PivotCache.CommandText Sheets("Totals").PivotTables("PivotTable2").PivotCache.CommandText = abc End Sub This isn't really what I'm trying to do, but not knowing what is causing an error in something as simple as this is driving me up a wall. The Pivot table at hand

问题 Run-time Polymorphism can be used to let the run-time to dynamically load the exact concrete class of an abstract class/interface. (You can take Animal/Dog, Vehicle/Car examples) But when we know the exact concrete class @coding-time (compile-time), does it really need to forcefully apply polymorphism? 回答1: When I write OO code, I tend to use most-general type I can on the left-hand side of the assignment. This immediately means that my answer to your question is - no. Here's the example:

问题 Is it possible to obtain version of a specific Grails plugin at runtime, let say in Bootstrap class? Or more generically, how to query loaded plugins from the parent Grails applications and obtain their names and version numbers? 回答1: The simplest way is to interact with the pluginManager bean. class BootStrap { def pluginManager def init = { servletContext -> // retrieve them all... pluginManager.allPlugins.each { plugin -> println "Plugin: ${plugin.name}, Version: ${plugin.version}" } //

问题 I need to choose a specific dimens.xml at runtime after my app checks for screen capabilities. I DON'T WANT ANDROID CHOOSE IT FOR ME by selecting automatically by project folder (\values, \values-large, ...). I have to do it manually due to the bad screen configuration (density and dimension) of my low-cost china tablet. Can I do that? 回答1: Have you tried to force configuration change? DisplayMetrics metrics = new DisplayMetrics(); metrics.densityDpi = DisplayMetrics.DENSITY_MEDIUM; metrics

问题 I need to build a DLL capable to load other DLLs at runtime; these other DLLs have a rather intimate relationship with the main DLL (this is Python and extensions), so they must have a common runtime. The main DLL must be a single file that can be simply copied on the target machine. The auxiliary DLLs will be placed in a different directory. So: "common runtime" means no static linking; "single file + simple copy" rules out the shared MS redistributables, especially when coupled with

问题 I need to reset a layout or dispose some of the controls on that layout according to some certain cases. But I couldn't find a way to do so. Do you have an idea about how to do? Thanks in advance. 回答1: Maybe you can just the hide the components, e.g. findViewById(R.id.the_id_of_the_view_to_hide).setVisibility(View.GONE); There are different parameters for the visibility. GONE hides the view and also frees up the space, the view used before, as if it was removed completely. 来源： https:/

问题 I am getting a practical issue and the issue can be dascribed as follows. We are developing a component (Say a plugin) to do some task when an event is triggered within an external CMS using the API provided by them. They have provided some jar libraries, So what we are doing is implementing an Interface provided by them. Then an internal method is called when an event is triggered. (The CMS is creating only one instance of class when the first event triggers, then it just executes the method

问题 As java programmers we have inherited a legacy app which is now being upgraded to java8. The App runs on an embedded jre which is shipped along with our App. We also ship tools.jar with the App, which is used to: 1) Compile .java files at run time; e.g. com.sun.tools.javac.Main.compile("SomeCustomClass.java"...). 2) Process annotations using the apt tool( package com.sun.mirror.apt); e.g. 'int aptReturnCode = com.sun.tools.apt.Main.process(myAnnotationProcessorFactory...); Problem is that the
