Question

这是我的包含的样子（链接器错误，所以可能与这些无关）：

#define WINVER 0x0500
#define _WIN32_WINNT 0x0500
#define _WIN32_IE 0x0501
#include <windows.h>
#include <CommCtrl.h>
#include "resources.h"
#include <iostream>
#include <string>
#include <vector>
#include <tchar.h>
#include <winspool.h>

以下是我尝试实施的方法：

HRESULT DisplayPrintPropertySheet(HWND hWnd)
{
    HRESULT hResult;
    PRINTDLGEX pdx = {0};
    LPPRINTPAGERANGE pPageRanges = NULL;

    pPageRanges = (LPPRINTPAGERANGE) GlobalAlloc(GPTR, 10 * sizeof(PRINTPAGERANGE));
    if (!pPageRanges)
        return E_OUTOFMEMORY;


    pdx.lStructSize = sizeof(PRINTDLGEX);
    pdx.hwndOwner = hWnd;
    pdx.hDevMode = NULL;
    pdx.hDevNames = NULL;
    pdx.hDC = NULL;
    pdx.Flags = PD_RETURNDC | PD_COLLATE;
    pdx.Flags2 = 0;
    pdx.ExclusionFlags = 0;
    pdx.nPageRanges = 0;
    pdx.nMaxPageRanges = 10;
    pdx.lpPageRanges = pPageRanges;
    pdx.nMinPage = 1;
    pdx.nMaxPage = 1000;
    pdx.nCopies = 1;
    pdx.hInstance = 0;
    pdx.lpPrintTemplateName = NULL;
    pdx.lpCallback = NULL;
    pdx.nPropertyPages = 0;
    pdx.lphPropertyPages = NULL;
    pdx.nStartPage = START_PAGE_GENERAL;
    pdx.dwResultAction = 0;



    hResult = PrintDlgEx(&pdx);

    if ((hResult == S_OK) && pdx.dwResultAction == PD_RESULT_PRINT)
    {
        StartDocPrinter(pdx.hDC,1,NULL);
        EndDocPrinter(pdx.hDC);

        cout << "Printer Succeeeded";

    }

    if (pdx.hDevMode != NULL)
        GlobalFree(pdx.hDevMode);
    if (pdx.hDevNames != NULL)
        GlobalFree(pdx.hDevNames);
    if (pdx.lpPageRanges != NULL)
        GlobalFree(pPageRanges);

    if (pdx.hDC != NULL)
        DeleteDC(pdx.hDC);

    return hResult;
}

每次尝试使用StartDoc,EndDoc,StartPage,EndPage,ect.

时，我都会一直收到这些未定义的链接器错误

链接器错误：

obj\Release\main.o:main.cpp|| undefined reference to `StartDocPrinterA@12'|
obj\Release\main.o:main.cpp|| undefined reference to `EndDocPrinter@4'|
||=== Build finished: 2 errors, 15 warnings ===|

如文档所述，这两个函数需要您链接winspool.lib。因此，你似乎没有这样做。

为什么我得到任何打印相关函数win32的未定义引用？
