Windows

Hello ,
I am creating a command bar using ::
CommandBar_Create(GetModuleHandle(NULL), hwnd, 1);

and then adding bitMap's and command Button using ::

CommandBar_AddBitmap(hwndCB, GetModuleHandle(NULL), bitMapId,4, GetSystemMetrics(SM_CXSMICON), GetSystemMetrics(SM_CYSMICON)); // 4 buttons  <br />
CommandBar_AddButtons(hwndCB,   4 ,  &tb);

I am facing 2 problems :
1) Not able to load more then 16X16 bit image.
2) Not able to increase the size of command bar and buttons.
Is there any way to change the size and color of statusBar aswell .
Can anyone suggest me some option.
Thanks
