    Deal or No Deal listbox prob

    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

    The following must be declared as GLOBAL.
    Code:
    HWND ButtonLow;
    Then call..
    Code:
    SendMessage(ButtonLow, LB_ADDSTRING, 0,	(LPARAM)"This is a string");

    Ok put
    Code:
    /* Deal or NO Deal .cpp */
    
    #include <windows.h>
    #include <stdio.h>
    
    HWND creatbuttonlistboxoffer;
    
    ....
    
    SendMessage(creatbuttonlistboxoffer, LB_ADDSTRING, 0,	(LPARAM)"This is a string");
    declared global. Getting error
    788 C:\Dev-Cpp\Project55DorND2\DealorNODeal.cpp `void creatbuttonlistboxoffer(HWND__*)' redeclared as different kind of symbol

    6 C:\Dev-Cpp\Project55DorND2\DealorNODeal.cpp previous declaration of `HWND__*creatbuttonlistboxoffer'

    6 C:\Dev-Cpp\Project55DorND2\DealorNODeal.cpp previous non-function declaration `HWND__*creatbuttonlistboxoffer'

    788 C:\Dev-Cpp\Project55DorND2\DealorNODeal.cpp conflicts with function declaration `void creatbuttonlistboxoffer(HWND__*)'

    Ok it works
    I see what I did and how it works. Thought the prob was with the sendmessage but it was with how I was setting up the window handle.

    Still trying to figure out how the odds are calculated for the offers.
