Well I can't seem to get it done with an index BMP but I did figure out one
way to get it done. Here is the code listing that lets you make a custom
toolbar with Win32 API. The code listing should be placed under WM_CREATE.
This listing works for 16x16 buttons. Trying to change ICON_X or ICON_Y to
anything other then 16 doesn't seem to work. If I set the value of these to
32 (or any other value) the buttons will get bigger but the toolbar itself
stays the same. This leaves me with only half the button being displayed.
Anyone know why that is?

[START OF CODE]

// enternal defines for TOTAL_ICONS, ICON_X, ICON_Y, ID_BUTTON_0,
ID_BUTTON_1, ID_BUTTON_2,
// external individual bitmaps: IDB_BUTTON_0, IDB_BUTTON_1, IDB_BUTTON_2
// external int: button0, button1, button2
// Toolbar ID = IDC_MAIN_TOOL

HWND hTool;  //handle to our toolbar
   TBBUTTON tbb[TOTAL_ICONS];  //array to hold our 2 toolbar buttons
   HBITMAP hbmBmp;
   g_himlIcons = ImageList_Create(ICON_X,ICON_Y,ILC_COLOR,TOTAL_ICONS,0);
//first we have to make our imagelist which holds our customs icons
   hbmBmp = LoadBitmap(GetModuleHandle(NULL),MAKEINTRESOURCE(IDB_BUTTON_0));
//then we load each icon into the imagelist
   button0 = ImageList_Add(g_himlIcons,hbmBmp,NULL);
   DeleteObject(hbmBmp);
   hbmBmp = LoadBitmap(GetModuleHandle(NULL),MAKEINTRESOURCE(IDB_BUTTON_1));
   button1 = ImageList_Add(g_himlIcons,hbmBmp,NULL);
   DeleteObject(hbmBmp);
   hbmBmp = LoadBitmap(GetModuleHandle(NULL),MAKEINTRESOURCE(IDB_BUTTON_2));
   button2 = ImageList_Add(g_himlIcons,hbmBmp,NULL);
   DeleteObject(hbmBmp);
   hTool =
CreateWindowEx(0,TOOLBARCLASSNAME,NULL,WS_CHILD|WS_VISIBLE,0,0,0,0,hwnd,(HME
NU)IDC_MAIN_TOOL,GetModuleHandle(NULL),NULL); //now let's create the actual
toolbar
   if(!hTool) MessageBox(hwnd,"Error Creating
Toolbar","Error",MB_OK|MB_ICONERROR);
   SendMessage(hTool,TB_BUTTONSTRUCTSIZE,(WPARAM)sizeof(TBBUTTON),0); //this
message is required for backward compatibility
   SendMessage(hTool,TB_SETIMAGELIST,0,(LPARAM)g_himlIcons); //now we tell
the toolbar which imagelist to use for the default state of buttons
   ZeroMemory(&tbb,sizeof(tbb)); //now lets setup the buttons to use our
custom bitmaps
   tbb[0].iBitmap = button0;  //index to the first bitmap we added to
imagelist
   tbb[0].idCommand = ID_BUTTON_0;
   tbb[0].fsState = TBSTATE_ENABLED;
   tbb[0].fsStyle = TBSTYLE_BUTTON;
   tbb[1].iBitmap = button1;  //index to second bitmap we added to imagelist
   tbb[1].idCommand = ID_BUTTON_1;
   tbb[1].fsState = TBSTATE_ENABLED;
   tbb[1].fsStyle = TBSTYLE_BUTTON;
   tbb[2].iBitmap = button2;  //index to third bitmap we added to imagelist
   tbb[2].idCommand = ID_BUTTON_2;
   tbb[2].fsState = TBSTATE_ENABLED;
   tbb[2].fsStyle = TBSTYLE_BUTTON;
   SendMessage(hTool, TB_ADDBUTTONS, TOTAL_ICONS, (LPARAM)&tbb); //now put
the buttons on the toolbar

[END OF CODE]

Does anyone know how to step through an indexed BMP file thus filling the
TBBUTTON structure with one single indexed bitmap (a single bitmap file
containing more then one image)?
