Question

我试过编译这段代码：

#include <windows.h>
#include <commctrl.h>


#define ID_TABCTRL 1
#define ID_EDIT 2
#define BTN_ADD 3
#define BTN_DEL 4
#define BTN_CLR 5
#define MAX_TAB_LEN 15

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
HWND hTab, hEdit;

int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
    PWSTR pCmdLine, int nCmdShow) {

    MSG  msg;
    WNDCLASSW wc = { 0 };
    wc.lpszClassName = L"Tab control";
    wc.hInstance = hInstance;
    wc.hbrBackground = GetSysColorBrush(COLOR_3DFACE);
    wc.lpfnWndProc = WndProc;
    wc.hCursor = LoadCursor(0, IDC_ARROW);

    RegisterClassW(&wc);
    CreateWindowW(wc.lpszClassName, L"Tab control",
        WS_OVERLAPPEDWINDOW | WS_VISIBLE,
        100, 100, 380, 230, 0, 0, hInstance, 0);

    while (GetMessage(&msg, NULL, 0, 0)) {

        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return (int)msg.wParam;
}

WINCOMMCTRLAPI BOOL WINAPI InitCommonControlsEx(_In_ const INITCOMMONCONTROLSEX *picce);

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg,
    WPARAM wParam, LPARAM lParam) {

    TCITEMW tie;
    wchar_t text[4];
    LRESULT count, id;
    INITCOMMONCONTROLSEX icex;

    switch (msg) {

    case WM_CREATE:

        icex.dwSize = sizeof(INITCOMMONCONTROLSEX);
        icex.dwICC = ICC_TAB_CLASSES;
        InitCommonControlsEx(&icex);

        hTab = CreateWindowW(WC_TABCONTROLW, NULL, WS_CHILD | WS_VISIBLE,
            0, 0, 200, 150, hwnd, (HMENU)ID_TABCTRL, NULL, NULL);

        hEdit = CreateWindowW(WC_EDITW, NULL, WS_CHILD | WS_VISIBLE | WS_BORDER,
            250, 20, 100, 25, hwnd, (HMENU)ID_EDIT, NULL, NULL);

        SendMessage(hEdit, EM_SETLIMITTEXT, MAX_TAB_LEN, 0);

        CreateWindowW(WC_BUTTONW, L"Add", WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,
            250, 50, 100, 25, hwnd, (HMENU)BTN_ADD, NULL, NULL);

        CreateWindowW(WC_BUTTONW, L"Delete", WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,
            250, 80, 100, 25, hwnd, (HMENU)BTN_DEL, NULL, NULL);

        CreateWindowW(WC_BUTTONW, L"Clear", WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,
            250, 110, 100, 25, hwnd, (HMENU)BTN_CLR, NULL, NULL);
        break;

    case WM_COMMAND:

        switch (LOWORD(wParam)) {

        case BTN_ADD:

            GetWindowTextW(hEdit, text, 250);

            if (lstrlenW(text) != 0) {

                tie.mask = TCIF_TEXT;
                tie.pszText = text;
                count = SendMessageW(hTab, TCM_GETITEMCOUNT, 0, 0);
                SendMessageW(hTab, TCM_INSERTITEMW, count,
                    (LPARAM)(LPTCITEM)&tie);
            }
            break;

        case BTN_DEL:

            id = SendMessageW(hTab, TCM_GETCURSEL, 0, 0);

            if (id != -1) {

                SendMessageW(hTab, TCM_DELETEITEM, 0, id);
            }
            break;

        case BTN_CLR:

            SendMessageW(hTab, TCM_DELETEALLITEMS, 0, 0);
            break;
        }
        break;

    case WM_DESTROY:

        PostQuitMessage(0);
        break;
    }

    return(DefWindowProcW(hwnd, msg, wParam, lParam));
}

好像是这个库：

#include <commctrl.h>

出现以下错误：

error LNK2019: unresolved external symbol        __imp__InitCommonControlsEx@4 referenced in function _WndProc@16   C:\Users\User\Desktop\Magshimim\Magshimim EX1\Magshimim EX1.obj  Magshimim EX1

现在代码是来自此处的示例代码：http://zetcode.com/gui/winapi/advancedcontrols/

所以我发现我的编译器有问题... 谁能帮我找到问题并改正？

编辑：这个问题不是重复的，因为被引用的重复以非常笼统的方式谈论错误本身，作为一个初学者，我没有能力从这样的问题中建立一个正确的答案，因为这个代码被许多检查过的人使用这个例子我认为它不能提出一个具体的问题

Answer 1

针对 comctl32.lib.

添加 #pragma comment(lib, "comctl32.lib") 或将 linker 设置调整为 link

您可以查看函数 MSDN article to find out, which library you are required to link against. Every Windows application is linked against kernel32.dll and every GUI application against user32.dll. Anything else needs to be specified explicitly¹ 底部的 table。
