CPP代码中的FileNotFound异常

Question

尝试在WCHAR中传递文件路径，但它告诉我WCHAR与常量WCHAR不兼容，因此尝试了硬编码，但仍收到异常

void Read_Title(WCHAR FilePath) {
//const WCHAR FILE_PATH = FilePath;
IPropertySetStorage *pPropSetStg = NULL;
IPropertyStorage *pPropStg = NULL;
PROPSPEC propspec;
PROPVARIANT propWrite;
PROPVARIANT propRead;
HRESULT hr = S_OK;

hr = StgOpenStorageEx(L"c:\\users\qs4vbn\desktop\siemens_training\project2\project2\main.cpp",
    STGM_DIRECT | STGM_SHARE_EXCLUSIVE |
    STGM_READWRITE,
    STGFMT_ANY,
    0,
    NULL,
    NULL,
    IID_IPropertySetStorage,
    reinterpret_cast<void**>(&pPropSetStg));

if (FAILED(hr))
    throw L"Failed StgOpenStorageEx";
}

Answer 1

您在此函数中的路径只包含第一段，并带有双反斜杠。

hr = StgOpenStorageEx(L"c:\\users\qs4vbn\desktop\siemens_training\project2\project2\main.cpp",
    STGM_DIRECT | STGM_SHARE_EXCLUSIVE |
    STGM_READWRITE,
    STGFMT_ANY,
    0,
    NULL,
    NULL,
    IID_IPropertySetStorage,
    reinterpret_cast<void**>(&pPropSetStg));

您是否尝试过使用带有双反斜杠的路径，如下所示

hr = StgOpenStorageEx(L"c:\\users\\qs4vbn\\desktop\\siemens_training\\project2\\project2\\main.cpp",
    STGM_DIRECT | STGM_SHARE_EXCLUSIVE |
    STGM_READWRITE,
    STGFMT_ANY,
    0,
    NULL,
    NULL,
    IID_IPropertySetStorage,
    reinterpret_cast<void**>(&pPropSetStg));
