如何在出现程序主窗体前显示闪屏!!!

[解决办法]
如果是C#，最简单的实现是引用Microsoft.VisualBasic.dll，然后：

C# code

[STAThread]static void Main(){    Application.EnableVisualStyles();    Application.SetCompatibleTextRenderingDefault(false);    Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase app =        new Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase();    app.SplashScreen = new SplashForm();    app.ApplicationContext.MainForm = new MainForm();    app.Run(new string[0]);    //Application.Run(new Form1());}
