Visual Studio Winforms 项目隐藏启动代码

问题描述

在 Visual Studio 中创建 VB.NET Winforms 项目时，有很多与初始化相关的代码似乎被隐藏了.有没有办法展示它，通过创建MyProject 和MyApplication 对象，创建和展示SplashScreen 最后定义和创建My.Application.ApplicationContext.MainForm?

When creating a VB.NET Winforms Project in Visual Studio, there's a lot of code related to initialization that seems to be hidden. Is there a way to show it in order to see which statements run from the very beginning, through creation of MyProject and MyApplication objects, creation and exhibition of SplashScreen and finally definition and creation of My.Application.ApplicationContext.MainForm?

也就是说，Console 应用程序项目有一个可见的 Sub Main()，我认为 Winforms 应用程序也应该有一个，但它是隐藏的，并且包含为以下项目创建实例的例程SplashScreen、主窗体等.我想更好地看到和理解这个流程.

That is, a Console application project has a Sub Main() that is visible, I presume a Winforms Application should have one too, but it is hidden and packed with the routines that create instances for SplashScreen, main Form and etc. I would like to see and understand better this flow.

谢谢！

推荐答案

点击项目 -->属性 -->应用程序选项卡 -->查看应用程序事件按钮(选项卡的右下角).

Click on Project --> Properties --> Application Tab --> View Application Events Button (bottom right of the tab).

在这里您可以创建一个 Application.Startup() 事件，相当于控制台应用程序中的Sub Main；至少它是您应该放置需要运行的代码的第一个位置.*使用代码编辑器顶部的下拉菜单；更改我的应用程序"到(MyApplication Events)"，并将OnCreateMainForm"更改为到启动".

Here you can create an Application.Startup() Event, which is equivalent to Sub Main in a Console Application; at least it's the first place you should place code that needs to run. *Use the DropDowns across the top of the code editor; change "MyApplication" to "(MyApplication Events)", and change "OnCreateMainForm" to "Startup".

这里还可以查看构造函数New()和OnCreateMainForm()，这是创建启动表单的地方.以下是所有这些的示例:

Here you can also view the Constructor New() and OnCreateMainForm(), which is where the startup form is created. Below is an example of all these together:
