Making selector circle activated by default

[meepokman]

Hi guys, I seem to have a small problem with my windows form application. Upon starting up the program, I need to click a circle selector in the windows form even though it appears as toggled before the program would work properly. Is it possible to find a way to make it toggled automatically when I start the program? The code is below.

void CzebraDlg::OnBnClicked01()
{
	// TODO: Add your control notification handler code here
	sprintf(Person, "01"); //write "A" to Person
	NumName=1;
}

I can't really see anything in the "properties" that I can use. Is there a fix?I'm using MFC for the GUI creation. Thanks a lot in advance.
