Deal or No Deal listbox prob

Having a prob sending items to the listboxes. There are three list boxes high side low side and offer.
Code:
SetDlgItemText(hwnd, IDC_TEXT, "This is a string
I have no idc-text as the example came from. Have tried sendmessage and setdlgitem. The prob seems to be addressing the listbox.

Code:
void creatbuttonlistboxoffer( HWND hwnd )
{
      UINT lbo;
     
HWND Button = CreateWindow(  
    "LISTBOX",   // predefined class 
    "NO DEAL!",       // button text 
    WS_VISIBLE | WS_CHILD | LBS_HASSTRINGS ,  // styles 
 
    // Size and position values are given explicitly, because 
    // the CW_USEDEFAULT constant gives zero values for buttons. 
    130,         // starting x position 
    190,         // starting y position 
    180,        // button width 
    100,        // button height 
    hwnd,       // parent window 

    NULL,       // No menu 
   (HINSTANCE) GetWindowLong(hwnd, GWL_HINSTANCE), 
    NULL);      // pointer not needed 
 
}
is how the listbox is setup. Have tried “creatbuttonlistboxoffer” in the sendmessage and setdlgitemtext spots id. Where idc-listbox or idc-text would be. I left them in the comments. Errors are can not convert void to hwnd etc. tried casting them that do not work eighter. Meow! Could redo code like winforge examples using resource style listbox but want to know how to send with using creatwindowex way. Attached I hope is code.

thank you meow
