Cant get editbox to display text

I'm using Visual C++ 4.
How do I make an editbox display text or a string variable.

if 4 works like 5&6, then....

CString teststr = "hello world";
//where teststr is the member variable to the control//
UpdateData(false);

CEdit edit1;

.....

edit1.SetWindowText( "hello, edit" );

CString str1( "my string" );
edit1.SetWindowText( str1 );
