Mainform.cs讀取例程超過兩次

Question

實際問題： Mainform讀取例程超過兩次。和MainForm的空 實例內部的所有組件和對象：

按鈕第一的優異

運行添加我的代碼：

namespace CheckNet 
{ 
    /// <summary> 
    /// Description of MainForm. 
    /// </summary> 
    delegate void Function(); 
    public partial class MainForm : Form

     public MainForm() 
     { 
      // 
      // The InitializeComponent() call is required for Windows Forms designer support. 
      // 
      InitializeComponent(); 
      Btn_Inicio.Click += new EventHandler (Btn_InicioClick); 
      // VerificationForm += new EventHandler (VerificationForm); 

      // 
      // TODO: Add constructor code after the InitializeComponent() call. 
      // 
     } 

     private DPFP.Template Template; 
     private DPFP.Template myTemplate; 
    // 





     void Btn_InicioClick(object sender, EventArgs e) 

     { 
      // call rutine ejecutar boton primera vez 
        // 
      if (this.panelContenedor.Controls.Count > 0) 
       this.panelContenedor.Controls.RemoveAt(0); 
       VerificationForm hijos = new VerificationForm(); 
       hijos.TopLevel = false; 
       hijos.FormBorderStyle = FormBorderStyle.None; 
       hijos.Dock = DockStyle.Fill; 
       this.panelContenedor.Controls.Add(hijos); 
       this.panelContenedor.Tag = hijos; 

       hijos.Show(); 


     } 




     void Button7Click(object sender, EventArgs e) 
     { 
      AddFormInPanel(new Hijo2());   
     } 


    private void AddFormInPanel(object formHijo) 
     { 
       if (this.panelContenedor.Controls.Count > 0) 
       this.panelContenedor.Controls.RemoveAt(0); 
       Form fh = formHijo as Form; 
       fh.TopLevel = false;

       fh.Show(); 
     } 



     void Close_bottonClick(object sender, EventArgs e) 
     { 
      Close();

如果用戶請求運行第二次相同的按鈕

個

VerificationForm程序和居民CaptureForm數字人裝置，並且不能讀取指紋

如何清空或重置過程或程序（MainForm的，VerificationForm和CaptureForm） 謝謝。

Answer 1

解決方案是：

修改的Program.cs

private static void Main (string [] args) 
{ 
Application.EnableVisualStyles(); 
Application.SetCompatibleTextRenderingDefault (false); 

      Fm1 MainForm = new MainForm(); 
      Application.Run (fm1); 

      if (fm1.ToRestart) 
       Application.Restart(); 
     } 

開始 ToRestart公共BOOL = FALSE;

void Btn_InicioClick (object sender, EventArgs e) 
{ 

ToRestart = true; 
      this.Close(); 

} 

重置指紋識別器和WinForm的控制
