components

问题 I've created a WinForms application that includes a custom component. The component needs to fire one of it's events on start up but, at the time the component's constructor is called, all of the event handlers are still null. What I need is an event that tells me the window owning the component has loaded and all the event handlers have been set. However, it appears that components have no Load event. In fact, it appears they don't come with any events at all with the sole exception of the

问题 We are working in one of the customer module. With the help of this module, we are calculating price for google cloud components like compute engine with attributes images, boot disk, region, snapshot etc. But we found that GCP is revising the prices and JSON is not modifying immediately. Newly revised pricing values comes in JSON after few days. So the price according to JSON and price in google cosole/calculator are different in this case. Is there any exchangeable format to get revised

问题 Sometimes, I want to write an simple application which will works on any Windows machine, without installing any programs or components (ex. .NET Framework), in a C# or Java like programming language.

问题 Do you know any components from jQuery with which you can preview .doc,.pdf,.jpg .... files in browser ? Thanks 回答1: If you really want to keep it all native inside the browser you can display images on their own and pdfs with pdf.js.

问题 I want to override the Angular Material select component (https://material.angular.io/components/select/overview) so that I can change the appearance of the now input-field to an icon button for example. I want to do this because it should somehow work as a dropdown. I already tried the overriding of the select and the component works very well like this.

问题 I'd like to make a login bar for an application and I can't figure out how to organize a series of JLabels and JTextFields such that they are organized in a horizontal grid without these same components being resized to fit each cell. I also want to make sure that the group of components isn't resized below a certain width. How can this be achieved? Edit: Thanks for the answers everyone. I'll have a look at MigLayout and SpringLayout later. Due to time constraints I'm going to have to make do

问题 Looking for some example code illustrating how to create at runtime TField Components associated with a dataset.
