C / C++ / MFC

Hi.
I send a "TEXT" from Form1 to Form2.
Sometimes it's good, sometimes it's not good.
When you send "TEXT" from Form1 to Form2, TEXT disappears from Form2.show.
---------------------------------------------
Hide   Expand    Copy Code
Form1.h

  private Burron1()

{

   Form2::Form fm;

    fm.viewText();
} 

Form2.h
namespace Form {
     public class Form
    {
      Form2()
        {
         void viewText();
        }
    }
}

void viewText()
{
   textBox1->Text="TEXT";
}
-------------------------------------------------------------
Only when Text's Form, no problem. I cann't see other ,  only did mySql. This disappeared the "TEXT". textBox->Text is a Empty. I sent "TEXT" can't look for any.

I want to know how to make the appearing thing.
Say me , please.
Thank you.
