  atom idParent,
  object events)

atom ID,hButton,hParent sequence Info,hFont

ID=Track:GetNextID() hParent=GetHandle(idParent)

if and_bits(Style,WS_TABSTOP) then Track:Event(onTab,ID,1) end if hButton= win:CreateWindowEx( StyleEx, extended window style "BUTTON", window class nameyou show text but it should be an atom Caption, window caption LLF:OR({Style,BS_PUSHBUTTON,BS_RADIOBUTTON,WS_VISIBLE,WS_CHILD}), window style xpos, initial x position ypos, initial y position width, initial width height, initial height hParent, parent window handle ID, control id instance(), program instance handle NULL creation parameters )

ClassCtl[CCID]=Info

this=ID return ID end function

myline

global constant Radio3=RB: Create( Radio,?,"Random After", CWindow, 25, 188, 120, 20, 0,0)

Hi Al thanks for the quick response,

I,m looking at Cherckbox.ew and it looks pretty much the same as Radio.ew.

I think I will have the same problem.

I guess what I want to ask is cou;ld you give me some examples of exceptable 

2nd elements [style]--window class name

      StyleEx,   -- extended window style
      "BUTTON",  -- window class name---HERE what do I put here?
                 -- "BUTTON" does not work because it's supposed tp be an atom
      Caption,   -- window caption

Thank you very much Al,

I Did get that error in SetCheck() in CheckBox.ew.

And you Fix fixed it. Using your above model I was able to create a CheckBox,
Which is close enough to the RadioButton I was tring for.

I read your next post and that's good I can use that Caption. I'll save me a
StaticText.
