问题 I have a VBA script for Excel that adds a small procedure in the active workbook. The final version will add a procedure that auto-saves backup copies of the workbook. The code requires the Microsoft Visual Basic for Applications Extensibility 5.3 library which I can add manually, but I'm interested in having a single script that can add that library into Excel and then use it. Here's the code that adds the library reference to Excel. It works. On Error Resume Next ' If library already

PHP __DIR__ evaluated runtime (late binding)?

由 烈酒焚心 提交于 2019-12-09 06:07:40
问题 Is it somehow possible to get the location of PHP file, evaluated at runtime? I am seeking something similar to the magic constant __DIR__ , but evaluated at runtime, as a late binding. Similar difference with self and static : __DIR__ ~ self ??? ~ static My goal is defining a method in an abstract class, using __DIR__ which would be evaluated respectively for each heir class. Example: abstract class Parent { protected function getDir() { // return __DIR__; // does not work return <<I need

Get a static property of an instance

问题 If I have an instance in PHP, what's the easiest way to get to a static property ('class variable') of that instance ? This $classvars=get_class_vars(get_class($thing)); $property=$classvars['property']; Sound really overdone. I would expect $thing::property or $thing->property EDIT: this is an old question. There are more obvious ways to do this in newer PHP, search below. 回答1: You need to lookup the class name first: $class = get_class($thing); $class::$property $property must be defined as

问题 I'm trying to put together a plugins system with .NET, and I'm not sure if I'm doing it correctly. The basis of the system is that a specific directory ({apppath}/Plugins/) will have a bunch of precompiled DLLs, and I want to look through each one with reflection, and for every class available, if it inherits a specific base class (this is defined in yet another DLL, but I'll go into that later), then create an instance of it and call a specific function in said instance.

问题 I'd like to access a COM library via late binding. How can I find out its progID? Type oClassType = Type.GetTypeFromProgID("THE MISSING PROGID"); 回答1: The progID is generally going to be of the form Library.Class, you can view what classes a COM library exposes using oleview. The feature you want in oleview is View TypeLib (three little red triangles). The Library name will be at the top and you will want to use the name of the class as seen under CoClasses 来源： https://stackoverflow.com

I am trying to create an application that creates objects from data that is read from an XML file. Using reflection I have managed to create the objects I need and assign some of the properties like primitive types and ENUM types.
