界面控件DevExpress WinForm新手指南——如何在应用启动时执行操作

DevExpress WinForm拥有180+组件和UI库，能为Windows Forms平台创建具有影响力的业务解决方案。

C#示例

对于C#项目，在Solution Explorer中找到Program.cs文件，该文件包含void Main()过程，开发人员可以在Application.Run方法调用之前在其中添加自定义代码。

C#

using DevExpress.XtraEditors;using System;using System.Windows.Forms;namespace WindowsFormsApplication1 {static class Program {/// <summary>/// The main entry point for the application./// </summary>[STAThread]static void Main() {//Add your code hereWindowsFormsSettings.ForceDirectXPaint();WindowsFormsSettings.EnableFormSkins();Application.EnableVisualStyles();Application.SetCompatibleTextRenderingDefault(false);Application.Run(new Form1());}}}

Visual Basic示例 – 方法1

使用这种方法，开发人员可以创建一个Main函数并将其设置为应用程序的入口点。

1. 在Solution Explorer中右键单击您的项目，然后在上下文菜单中选择Properties。

2. 取消选中Enable application framework，然后在Application选项卡中将Startup object设置为Sub Main。

VB.NET

Public Class Form1Shared Sub Main()Application.EnableVisualStyles()Application.SetCompatibleTextRenderingDefault(False)Application.Run(New Form1) 'Specify the startup formEnd SubEnd Class

4. 在Application.Run方法调用之前插入要执行的代码。

VB.NET

Public Class Form1Shared Sub Main()'Add your code hereDevExpress.XtraEditors.WindowsFormsSettings.ForceDirectXPaint()DevExpress.XtraEditors.WindowsFormsSettings.EnableFormSkins()Application.EnableVisualStyles()Application.SetCompatibleTextRenderingDefault(False)Application.Run(New Form1) 'Specify the startup formEnd SubEnd Class

Visual Basic示例 – 方法2

通过这种方法，您可以订阅应用程序的Startup事件来执行自定义操作。

1. 在Solution Explorer中右键单击您的项目，然后在上下文菜单中选择Properties。

2. 在Application选项卡中单击View Application Events按钮。

3. 订阅打开的ApplicationEvents.vb文件中的Startup事件。

4. 在生成的Startup事件处理程序中插入要执行的代码。

VB.NET

Imports DevExpress.XtraEditorsImports Microsoft.VisualBasic.ApplicationServicesNamespace My' The following events are available for MyApplication:' Startup: Raised when the application starts, before the startup form is created.' Shutdown: Raised after all application forms are closed. This event is not raised if the application terminates abnormally.' UnhandledException: Raised if the application encounters an unhandled exception.' StartupNextInstance: Raised when launching a single-instance application and the application is already active.' NetworkAvailabilityChanged: Raised when the network connection is connected or disconnected.Partial Friend Class MyApplicationPrivate Sub MyApplication_Startup(sender As Object, e As StartupEventArgs) Handles Me.Startup'Add your code hereWindowsFormsSettings.ForceDirectXPaint()WindowsFormsSettings.EnableFormSkins()End SubEnd ClassEnd Namespace
