I have a problem with using listBox1. I have a two forms form1 and
form2. In form1 are controls listBox1, textBox1 and button witch
creating object of class Form2. In class Form2 I create a pointer to
object of class Form1. I don't known how to use method add(), where
can I find it. From Form1 I can add value like this this->listBox1-
>Items[1]->Add("aaaa"); but from Form2 when I try to get this methodI cant find it. I have textBox1 on Form1 and I can change text in this
control like this fm1->Controls["textBox1"]->Text = "text in box"; .
But Text is property of class not method like add().
How can I use add() method from the Form2 to listBox in another form?
VS2005Pro, .net Framework 2.0
Below I attach the listening
