问题 Inno Setup: Dynamically add all files in a folder and add a component tag, so during running of the setup the user can select custom setup and select which files to copy. I'd like to create a Inno Setup file that will grab files in a folder that users can put in there, without having to modify the Inno Setup file each time a new file is added.

问题 I've used frames in Delphi for years, and they are one of the most powerful features of the VCL, but standard use of them seems to have some risk such as: It's easy to accidentally move or edit the frame sub-components on a frame's host form without realising that you are 'tweaking' with the frame - I know this does not affect the original frame code, but it's generally not what you would want. When working with the frame you are still exposed to its sub-components for visual editing, even

问题 I am learning Full-stack Angular4, and wanted to know how would I be able to get data from a get call from one component into another so I can relay the data into the html page with {{data.name}}?

What am I doing wrong? UPDATE: my shared service: import {Injectable} from "@angular/core"; import {Http, Response,

问题 I need to be able to add & remove Angular components on the fly. To do so, I'm using loadIntoLocation and dispose methods, like it: Adding a component (from a layout manager): this.m_loader.loadIntoLocation(MyComponent, this.m_element, 'content').then(_componentRef => { // Create the window and set its title: var component: MyComponent = (_componentRef.instance); component.ref = _componentRef; // init the component content }); Removing a component (from the component): this.ref.dispose(); It
