    Question Adding user drawn bitmaps to an existing toolbar

    i wonder if anyone can help me with this small problem

    i have a toolbar, that displays 3 standard toolbal buttons, NEW, OPEN, SAVE. This displays and works okay, i can add other system buttons using this method, but i cant create my own buttons or at least add my bitmaps to the buttons. The code i used came from the site that everyone seems to mention on this board, but i forgot the address, but i will show the code for the area i need to add the buttons below.

    Code:
    case WM_CREATE:
    		{
    			HWND hTool;
    			TBBUTTON tbb[3];//define array of toolbar buttons
    			TBADDBITMAP tbab;
    
    			HWND hStatus;
    			int statwidths[] = {100, -1};
    
    			CLIENTCREATESTRUCT ccs;
    
    			// Create MDI Client
    
    			// Find window menu where children will be listed
    			ccs.hWindowMenu  = GetSubMenu(GetMenu(hwnd), 2);
    			ccs.idFirstChild = ID_MDI_FIRSTCHILD;
    
    			g_hMDIClient = CreateWindowEx(WS_EX_CLIENTEDGE, "mdiclient", NULL,
    				WS_CHILD | WS_CLIPCHILDREN | WS_VSCROLL | WS_HSCROLL | WS_VISIBLE,
    				CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
    				hwnd, (HMENU)IDC_MAIN_MDI, GetModuleHandle(NULL), (LPVOID)&ccs);
    
    			if(g_hMDIClient == NULL)
    				MessageBox(hwnd, "Could not create MDI client.", "Error", MB_OK | MB_ICONERROR);
    
    			// Create Toolbar
    
    			hTool = CreateWindowEx(0, TOOLBARCLASSNAME, NULL, WS_CHILD | WS_VISIBLE, 0, 0, 0, 0,
    				hwnd, (HMENU)IDC_MAIN_TOOL, GetModuleHandle(NULL), NULL);
    			if(hTool == NULL)
    				MessageBox(hwnd, "Could not create tool bar.", "Error", MB_OK | MB_ICONERROR);
    
    			// Send the TB_BUTTONSTRUCTSIZE message, which is required for
    			// backward compatibility.
    			SendMessage(hTool, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);
    			
    			tbab.hInst = HINST_COMMCTRL;
    			tbab.nID = IDB_STD_LARGE_COLOR;
    			SendMessage(hTool, TB_ADDBITMAP, 0, (LPARAM)&tbab);
    
    			ZeroMemory(tbb, sizeof(tbb));
    			tbb[0].iBitmap		= STD_FILENEW;		tbb[0].fsState		= TBSTATE_ENABLED;
    			tbb[0].fsStyle		= TBSTYLE_BUTTON;	tbb[0].idCommand	= IDM_FILE_NEW;
    
    			tbb[1].iBitmap		= STD_FILEOPEN;		tbb[1].fsState		= TBSTATE_ENABLED;
    			tbb[1].fsStyle		= TBSTYLE_BUTTON;	tbb[1].idCommand	= IDM_FILE_OPEN;
    
    			tbb[2].iBitmap		= STD_FILESAVE;		tbb[2].fsState		= TBSTATE_ENABLED;
    			tbb[2].fsStyle		= TBSTYLE_BUTTON;	tbb[2].idCommand	= IDM_FILE_SAVE_AS;
    			
    
    			SendMessage(hTool, TB_ADDBUTTONS, sizeof(tbb)/sizeof(TBBUTTON), (LPARAM)&tbb);
    
    			// Create Status bar
    
    			hStatus = CreateWindowEx(0, STATUSCLASSNAME, NULL,
    				WS_CHILD | WS_VISIBLE | SBARS_SIZEGRIP, 0, 0, 0, 0,
    				hwnd, (HMENU)IDC_MAIN_STATUS, GetModuleHandle(NULL), NULL);
    
    			SendMessage(hStatus, SB_SETPARTS, sizeof(statwidths)/sizeof(int), (LPARAM)statwidths);
    			SendMessage(hStatus, SB_SETTEXT, 0, (LPARAM)"Hi there :)");
    		}
    		break;
    does anyone have any ideas??

    i am using msvc6.0 and using win32 and c

    thanx in advance

    You can have a look at a complete sample here(see dll_toolbar.c):
    http://www.exhedra.com/vb/scripts/Sh...=7011&lngWId=3

    But here are the steps:
    1. Add a bitmap containing your toolbar icons as a resource. It should contain a series of 16x16 icons.
      Code:
      // Bitmap containing toolbar icons...
      TOOLBAR_ICONS BITMAP "dll_tbicons.bmp"
    2. Add the bitmap to the toolbar control and return the index of the first image.
      Code:
      // Add custom images...
      tbAddBitmap.hInst = g_hInstance; /* App's hInstance. */
      tbAddBitmap.nID = TOOLBAR_ICONS; /* Resource id of bitmap */
      iImageOffset = SendMessage(g_hwndToolbar, TB_ADDBITMAP, 5, (LPARAM) &tbAddBitmap); /* Bitmap contains 5 icons */
    3. Use the images with your buttons.
      Code:
      tbb[3].iBitmap = iImageOffset + 0; // Use first icon
      tbb[4].iBitmap = iImageOffset + 1; // Use second button


    P.S I see you are using large buttons so icons should be 24x24(or possibly 26x26, docs are unclear) rather that 16x16.

    okay i added the code from that link but the images are not displaying

    the compiler dont like this line

    Code:
    // Create a toolbar that has ToolTips associated with it...
    	g_hwndToolbar = CreateWindowEx(0, TOOLBARCLASSNAME, NULL,
    			             WS_CHILD | TBSTYLE_TOOLTIPS | WS_CLIPSIBLINGS, 0, 0, 0, 0,
    				     hwnd, (HMENU) 0, (HINSTANCE) GetWindowLongPtr(hwnd, GWL_HINSTANCE), NULL);
    although i am not too sure if this is the problem, i made the following modifications
    Code:
    // Create a toolbar that has ToolTips associated with it...
    			g_hToolbar = CreateWindowEx(0, TOOLBARCLASSNAME, NULL,
    						 WS_CHILD | TBSTYLE_TOOLTIPS | WS_CLIPSIBLINGS, 0, 0, 0, 0,
    						 hwnd, (HMENU) IDC_MAIN_TOOL, (HINSTANCE)GetModuleHandle(0), NULL);
    here is the complete CASE statement again, with the modifications
    Code:
    case WM_CREATE:
    		{
    			CLIENTCREATESTRUCT ccs;
    			UINT iButton, iImageOffset;
    			TBADDBITMAP tbAddBitmap;
    
    			INT idCommands[COUNT_BUTTONS];
    
    			HWND hStatus;
    			int statwidths[] = {100, -1};
    			// Toolbar buttons...
    			TBBUTTON tbb [COUNT_BUTTONS] = {
    				{STD_FILENEW,  0, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0, 0, 0},
    				{STD_FILEOPEN, 0, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0, 0, 0},
    				{STD_FILESAVE, 0, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0, 0, 0},

    				{5, 0, TBSTATE_ENABLED, TBSTYLE_SEP, 0, 0, 0},
    
    				{TBICON_WORD_WRAP,        0, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0, 0, 0 },   // Wordwrap
    				{TBICON_CONV_LINE_BREAKS, 0, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0, 0, 0 },   // Convert line breaks
    
    				{5, 0, TBSTATE_ENABLED, TBSTYLE_SEP, 0, 0, 0},
    
    				{TBICON_CALCULATOR, 0, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0, 0, 0 }, // Calculator
    			};
    
    			// Toolbar captions. Supposedly strings should be double null terminated...

    okay, i ran an error checker through the code and get an error on this section of code

    Code:
    SendMessage(g_hToolbar, TB_ADDBITMAP, 0, (LPARAM) &tbAddBitmap);
    the error checker reports the following error:

    Not enough storage is available to process this command
    does anyone know why i get this error as i have no idea

    thanx again
