C # Winform form using a single pass value parent form Form Examples

Description: In recent HALCON doing C # programming and, to use a single example of changing the value of the parameter of the parent form of a subform. This example is a simplified version

       1, click system settings

                 

      2, the pop-subform, after which the modified input parameter points Edit button

               

      3, click the OK button, the subform off, change the value of the main form textbox

              

    4, the singleton procedure is as follows:

 public class Student
    {
        // Create Singleton internal static class method 
        Private Student () {} // private constructor 
        class the Nested
        {
            internal static readonly Student instance = new Student();
        }
        public static Student Instance
        {
            get { return Nested.instance; }
        }

        // create the field and its properties 
        Private  String name;
         public  String   the Name
        {
            get { return name; }
            set { name = value; }
        }
        private int chinses;

        public int Chinses
        {
            get { return chinses; }
            set { chinses = value; }
        }
        private int math;

        public int Math
        {
            get { return math; }
            set { math = value; }
        }
    }

   5, the child window procedure

        public Setting()
        {
            InitializeComponent();
        }
        STU Student = Student.Instance; // create a single class of embodiments

        private void Setting_Load(object sender, EventArgs e)
        {
           
        }

        private void BtnChange_Click(object sender, EventArgs e)
        {
            stu.Name = the this .textBoxName.Text; // the sub-display window textbox property value assigned to the field 
            stu.Chinses = Convert.ToInt32 ( the this .textBoxChinese.Text);
            stu.Math = Convert.ToInt32(this.textBoxMath.Text);
        }

   6, the parent form program

STU = Student.Instance Student; // Create a singleton 
        Private  void MainForm_Load ( Object SENDER, EventArgs E)
        {
            the this .tBName.Text = " Weber " ; // main window display content loading 
            the this .tBChinese.Text = Convert.ToString ( 89 );
             the this .tBMath.Text = Convert.ToString ( 90 );
        }

        private void ToolStripButton1_Click(object sender, EventArgs e)
        {
            Setting mySetting = new Setting();
            mySetting.ShowDialog (); // sub pop-up window

            the this .tBName.Text = stu.Name; // value field attribute value assigned textbox 
            the this .tBMath.Text = Convert.ToString (stu.Math);
             the this .tBChinese.Text = Convert.ToString (stu.Chinses);

        }
