Hi everyone, I am working on application with more than 1 form but I don't use MDI. In form1 I have a treeView and a ListView. On form2, I have a textBox and a button. The flow is when I click the button on form2, the treeView on form1 will add new node.

I've tried this one but it is error and I don' understand the error:

private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
Form1->treeView1->Nodes->Add(textBox1->Text);
}

Thank you very much.

Regardless of how you go, you'll want to put some kind of event on form2 that's public. You can make the button click event public, if you like. The it's usually cleaner to write a specific event for sharing outside a parent form.

If Form1 instantiates Form2, have it listen to the event of the instance it created and react accordingly. If Form1 and Form2 share a parent, have the parent listen to the form2 event and tell form1 what happened.

Some kind of event pattern is pretty much the only solution is you want to react to a button press.
