Hi. I have a problem with creation of toolbar in Win32 C++ application. I want to reproduce an example from MSDN: https://learn.microsoft.com/en-us/windows/win32/controls/create-toolbars.
Below is source code:
HINSTANCE hInst;
HIMAGELIST g_hImageList = NULL;
#define IDM_OPEN 1
#define IDM_NEW 2
#define IDM_SAVE 3
HWND CreateSimpleToolbar(HWND hWndParent)
{
// Declare and initialize local constants.
const int ImageListID = 0;
const int numButtons = 3;
const int bitmapSize = 16;
const DWORD buttonStyles = BTNS_AUTOSIZE;
// Create the toolbar.
HWND hWndToolbar = CreateWindowEx(0, TOOLBARCLASSNAME, NULL,
WS_CHILD | TBSTYLE_WRAPABLE, 0, 0, 0, 0,
hWndParent, NULL, g_hInst, NULL);
if (hWndToolbar == NULL)
return NULL;
// Create the image list.
g_hImageList = ImageList_Create(bitmapSize, bitmapSize, // Dimensions of individual bitmaps.
ILC_COLOR16 | ILC_MASK, // Ensures transparent background.
numButtons, 0);
// Set the image list.
SendMessage(hWndToolbar, TB_SETIMAGELIST,
(WPARAM)ImageListID,
(LPARAM)g_hImageList);
// Load the button images.
SendMessage(hWndToolbar, TB_LOADIMAGES,
(WPARAM)IDB_STD_SMALL_COLOR,
(LPARAM)HINST_COMMCTRL);
// Initialize button info.
// IDM_NEW, IDM_OPEN, and IDM_SAVE are application-defined command constants.
TBBUTTON tbButtons[numButtons] =
{
{ MAKELONG(STD_FILENEW, ImageListID), IDM_NEW, TBSTATE_ENABLED, buttonStyles, {0}, 0, (INT_PTR)L"New" },
{ MAKELONG(STD_FILEOPEN, ImageListID), IDM_OPEN, TBSTATE_ENABLED, buttonStyles, {0}, 0, (INT_PTR)L"Open"},
{ MAKELONG(STD_FILESAVE, ImageListID), IDM_SAVE, 0, buttonStyles, {0}, 0, (INT_PTR)L"Save"}
};
// Add buttons.
SendMessage(hWndToolbar, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);
SendMessage(hWndToolbar, TB_ADDBUTTONS, (WPARAM)numButtons, (LPARAM)&tbButtons);
// Resize the toolbar, and then show it.
SendMessage(hWndToolbar, TB_AUTOSIZE, 0, 0);
ShowWindow(hWndToolbar, TRUE);
return hWndToolbar;
}
But when building the application, I get the following error: LNK2019 unresolved external symbol reference imp__ImageList_Create@20 in function "struct HWND * cdecl CreateToolbar(struct HWND *)" (?CreateToolbar@@YAPAUHWND__@@PAU1@@Z).
Why does it take place? Please help me fix it. Thanks in advance.

Try this.
