Question

我正试图在visual studio 2012中使用WBF（Windows生物识别框架）捕获生物识别样本

这是我的主要.cpp文件：

// FingerPrint.cpp：定义控制台应用程序的入口点。

#include "stdafx.h"
#include "Windows.h"
#include "Stdio.h"
#include "Conio.h"
#include "Winbio.h"
HRESULT CaptureSample();
int _tmain(int argc, _TCHAR* argv[])
{
    HRESULT CaptureSample();
    return 0;
}
HRESULT CaptureSample()
{
    HRESULT hr = S_OK;
    WINBIO_SESSION_HANDLE sessionHandle = NULL;
    WINBIO_UNIT_ID unitId = 0;
    WINBIO_REJECT_DETAIL rejectDetail = 0;
    PWINBIO_BIR sample = NULL;
    SIZE_T sampleSize = 0;

    // Connect to the system pool. 
    hr = WinBioOpenSession( 
            WINBIO_TYPE_FINGERPRINT,    // Service provider
            WINBIO_POOL_SYSTEM,         // Pool type
            WINBIO_FLAG_RAW,            // Access: Capture raw data
            NULL,                       // Array of biometric unit IDs
            0,                          // Count of biometric unit IDs
            WINBIO_DB_DEFAULT,          // Default database
            &sessionHandle              // [out] Session handle
            );
    if (FAILED(hr))
    {
        wprintf_s(L"\n WinBioOpenSession failed. hr = 0x%x\n", hr);
        goto e_Exit;
    }

    // Capture a biometric sample.
    wprintf_s(L"\n Calling WinBioCaptureSample - Swipe sensor...\n");
    hr = WinBioCaptureSample(
            sessionHandle,
            WINBIO_NO_PURPOSE_AVAILABLE,
            WINBIO_DATA_FLAG_RAW,
            &unitId,
            &sample,
            &sampleSize,
            &rejectDetail
            );
    if (FAILED(hr))
    {
        if (hr == WINBIO_E_BAD_CAPTURE)
        {
            wprintf_s(L"\n Bad capture; reason: %d\n", rejectDetail);
        }
        else
        {
            wprintf_s(L"\n WinBioCaptureSample failed. hr = 0x%x\n", hr);
        }
        goto e_Exit;
    }

    wprintf_s(L"\n Swipe processed - Unit ID: %d\n", unitId);
    wprintf_s(L"\n Captured %d bytes.\n", sampleSize);


e_Exit:
    if (sample != NULL)
    {
        WinBioFree(sample);
        sample = NULL;
    }

    if (sessionHandle != NULL)
    {
        WinBioCloseSession(sessionHandle);
        sessionHandle = NULL;
    }

    wprintf_s(L"\n Press any key to exit...");
    _getch();

    return hr;
}

这是我在构建项目时得到的结果：

当我开始没有调试时：一个控制台窗口打开说“按任意退出...”然后如果我这样做，窗口关闭..

Answer 1

int _tmain(int argc, _TCHAR* argv[])
{
    HRESULT CaptureSample();
    return 0;
}

替换

    HRESULT CaptureSample();

与

    CaptureSample();

在您的代码HRESULT CaptureSample();中只是前向声明，而不是函数调用，因此main函数不执行任何操作。调试你可以看到的程序，调试器不会停在这一行上。关于Cannot find or open the PDB file消息，只需忽略它们，就不需要调试系统库。

运行成功构建项目时，我在控制台中没有输出
