MessageBox method

[CooLWong]

I using Visual C++ express edition 2005, when i click a button, it will shown a messagebox. I can write a simple code to show it, but it don hav error message, warning message, or information message.

This is my simple code:

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
	System::Windows::Forms::MessageBox::Show("Example", "YA");
}

Any body can help me to change the code to show the error message or warning message???
