启动时隐藏表格

Question

我有一个程序，只需要一个NotifyIcon按预期工作。所以我一直试图让程序启动时隐藏主窗体。

在frmMain_Load，我都尝试

this.Hide(); 
this.Visible = false; 

没有成功。

他们在其他方法中工作，如NotifyIcon_MouseClick方法，但我希望它隐藏在Load。

我在另外一个问题在这里看到的那么，马蒂亚斯建议是：

BeginInvoke(new MethodInvoker(delegate 
{ 
    Hide(); 
})); 

这个工作，但是当我启动该程序，我可以看到闪烁的形式实快。这比没有好，但我想知道是否有更好的解决方案。

谢谢。

Answer 1

// In Your Program.cs Convert This 
static void Main() 
{ 
    Application.EnableVisualStyles(); 
    Application.SetCompatibleTextRenderingDefault(false); 
    Application.Run(new Form1()); 
} 

// To This 
static void Main() 
{ 
    Application.EnableVisualStyles(); 
    Application.SetCompatibleTextRenderingDefault(false); 
    Form1 TheForm = new Form1(); 
    Application.Run(); 
} 

// Call Application.Exit() From Anywhere To Stop Application.Run() Message Pump and Exit Application 

Answer 2

不要在表单上调用Show或ShowDialog，你可以让你的Application.Run目标是一个自定义的类，然后实例化一个表单并且不会显示或创建一个NotifyIcon实例并处理所有的事情。

Answer 3

有一个简单的方法，如果你的程序的Visual Studio生成的Program.cs文件默认：

[STAThread] 
static void Main() 
{ 
    Application.EnableVisualStyles(); 
    Application.SetCompatibleTextRenderingDefault (false); 
    Application.Run (new MainForm()); 
} 

调用Run简单的事实会的确使窗体可见。试着做你的窗体的属性如下：

1. 设置WindowState到Minimized
2. 设置ShowInTaskbar到false

这应该做的伎俩！

Answer 4

您也可以将this.hide = true放入form_shown事件中。我相信事件只会在加载事件之后触发一次。尽管如果你的表单有很多控件和/或计算机速度很慢，你可能会看到闪烁。

如果您的程序不需要运行窗体，那么最好的方法是根本没有窗体。在程序代码中设置您的NotifyIcon，然后输入一个循环，直到您想通过设置某个值或调用某种方法退出该程序。在此示例中，将UserExitCalled设置为true（Program.UserExitCalled = true）将导致程序退出。这里是一个简单的例子：

static class Program { 
    internal static Boolean UserExitCalled; 

    /// <summary> 
    /// The main entry point for the application. 
    /// </summary> 
    [STAThread] 
    static void Main() { 
     Application.EnableVisualStyles(); 
     Application.SetCompatibleTextRenderingDefault(false); 

     // Setup your tray icon here 

     while (!UserExitCalled) { 
      Application.DoEvents(); // Process windows messages 
      Thread.Sleep(1); 
     } 

     return; 
    } 
} 

这里从我的一个系统托盘应用程序的完整程序类作为工作示例。

Answer 6

我所做的只是改变这一属性： Application.OpenForms["Form1"].Opacity = 0;
