Text Box Display (Without building public interface)

Text Box Display (Without building public interface)

• Leaf.

  Mr.Nahgum Thanks for your reply.

  Sorry for my inconvenience for not to put my query as crystal clear. Let me explain you clearly.

  I have a form named as MyMain. It has two controls. One textbox (named as TxtResultTextBox) and one Command Button (named as BtnShowSecondaryForm). This form is my default form, so it should visible on my startup. Its windows state is maximized.

  And I have another form named as Secondary. It also contains one textbox (named as TxtSourceTextBox) and one Command Button (BtnSendText) Respectively.

  While clicking on the BtnShowSecondaryForm command button of my MyMain form, The Secondary Form should visible. Its windows state is Normal. It is smaller than MyMain form. So user can see both the forms but the focus now with Secondary Form. MyMain form showing on the backside of it.

  I don’t want to hide my MyMain form when user clicks on the button btnShowSecondaryForm (ie when Secondary form is visible).

  Now assume that, User enters some texts or values on TxtSourceTextBox Textbox of my Secondary form. Once he clicks on the Command Button BtnSendText, I have to send the text/values he enters to my MyMain form’s TxtResultTextBox and immediately close my Secondary form. This is what I need.

  I don’t like to create any instance to MyMain form which opens another instace.

  I hope you may get it clear now.

  That's not what you asked orignally. You said "press command button, my first form should be closed and second form should be on visible". First form CLOSED. To answer the question as you have described the second time, the below will do the job.

   

  Secondary:

   

  public string TxtSourceTextBoxText

  {

  get { return this.txtSourceTextBox.Text; }

  set { this.txtSourceTextBox.Text = value; }

  }

  private void btnSendText_Click(object sender, EventArgs e)

  {

  this.DialogResult = DialogResult.OK;

  this.Close();

  }

  MyMain:

  private void btnShowSecondaryForm_Click(object sender, EventArgs e)

  {

  Secondary secondary = new Secondary();

  secondary.TxtSourceTextBoxText = this.txtResultTextBox.Text;

  if (secondary.ShowDialog() == DialogResult.OK)

  {

  this.txtResultTextBox.Text = secondary.TxtSourceTextBoxText;

  }

  }

  Hi

  What you have done is the following: you define an local variable called SF in BtnSend_CLick so when the execution leaves the function the SF goes out of scope and will be subject to garbage collection. To correct this problem you have many ways you can adopt, however I will give you the simplest solution.
  Change the SecondForm as follows:
  
  class SecondForm : Form{
  private static SecondForm instance; // a static field that keeps track of the current instance of SecondForm
  
  // this property returns the current instance of the SeconfForm, if it does not exist it is created
  public static SecondForm Instance{
  get{
  if(instance == null || !instance.Created){
  instance = new SecondForm();
  }
  return instance;
  }
  }
  }

  now back to your FirstForm
  

  public void BtnSend_Click(object sender, EventArgs e)

  {

  SecondForm SF = SecondForm.Instance; // get the current instance
  SF.AllowDrop=true;

  SF.TextBox1.Text = This.TextBox1.Text;

  This.close();

  SF.show();

  SF.TextBox1.Focus();

  }

  Hope it helps

  regards

  Dear Mr. Z.Y.S

  Thanks for your prompt reply.

  It is working but it doesn’t satisfy my condition. Because “instance = new SecondForm();” statement creating a new instance of my form (form2), and passes the value to that new form not to the original form (form2).

  I don’t like to close or hide the base form (it is meaningless).

  Is it possible to take clone (Mirroring) to so and so textbox in C#

  So Anymore comment
  Regards

  Thanks Mr. Nahguam, I will check your latest coding too.Thanks for all who were willing to solve my problem. Finally I got the solution; it is working fine with my following codes.

  MyMain Form

  private void BtnShowSecondaryForm _Click(object sender, System.EventArgs e)

  {

  Secondary SF = new Secondary ();

  SF.txtout= TxtResultTextBox;

  SF.ShowDialog();

  }

  Secondary Form

  public System.Windows.Forms.TextBox txtout ;

  private void BtnSendText _Click(object sender, System.EventArgs e)

  {

  if(TxtSourceTextBox.Text != "")

  {

  try

  {

  txtout.Text = this.TxtSourceTextBox.Text;

  this.Close();

  }

  catch (Exception xe)

  {

  Console.WriteLine(""+ xe);

  }

  }

  }

  Form 2:

  
  

  public partial class Form2 : Form
  {
  public Form2()
  {
  InitializeComponent();
  }
  

  public string TextBoxText
  {
  set { textBox1.Text = value; }
  }
  }

  
  

  Form 1:

  
  

  public partial class Form1 : Form
  {
  public Form1()
  {
  InitializeComponent()
  }
  
  private string text;
  
  public void Form2ThreadStart()
  {
  Form2 form2 = new Form2();
  form2.TextBoxText = text;
  Application.Run(form2);
  }
  
  private void button1_Click(object sender, EventArgs e)
  {
  text = this.textBox1.Text;
  Thread thread = new Thread(new ThreadStart(Form2ThreadStart));
  thread.Start();
  this.Close();
  }
  }
