Property Value

Type: System::Boolean

true if the Help button is shown in the dialog box; otherwise, false. The default value is false.

The following code example illustrates the creation of new ColorDialog. This example requires that the method is called from within an existing form that has a TextBox and Button placed on it.

private:
   void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      ColorDialog^ MyDialog = gcnew ColorDialog;
      // Keeps the user from selecting a custom color.
      MyDialog->AllowFullOpen = false;
      // Allows the user to get help. (The default is false.)
      MyDialog->ShowHelp = true;
      // Sets the initial color select to the current text color.
      MyDialog->Color = textBox1->ForeColor;

      // Update the text box color if the user clicks OK 
      if ( MyDialog->ShowDialog() == ::System::Windows::Forms::DialogResult::OK )
      {
         textBox1->ForeColor = MyDialog->Color;
      }
   }
