void AppendTextBox1Text()
{
   // Determine if text is selected in textBox1.
   if ( textBox1->SelectionLength == 0 )

   // No selection made, return.
   return;

   // Determine if the text being appended to textBox2 exceeds the MaxLength property.
   if ( (textBox1->SelectedText->Length + textBox2->TextLength) > textBox2->MaxLength )
         MessageBox::Show( "The text to paste in is larger than the maximum number of characters allowed" ); // Append the text from textBox1 into textBox2.
   else
         textBox2->AppendText( textBox1->SelectedText );
}
private void AppendTextBox1Text()
{
   // Determine if text is selected in textBox1.
   if(textBox1.SelectionLength == 0)
      // No selection made, return.
      return;

   If textBox1.SelectedText.Length + textBox2.TextLength > textBox2.MaxLength Then
      MessageBox.Show("The text to paste in is larger than the maximum number of characters allowed")
      ' Append the text from textBox1 into textBox2.
   Else
      textBox2.AppendText(textBox1.SelectedText)

Comentarios

Puede utilizar este método para agregar texto al texto existente en el control en lugar de usar el operador de concatenación (+) para concatenar texto para el Text propiedad.You can use this method to add text to the existing text in the control instead of using the concatenation operator (+) to concatenate text to the Text property.
