Question

我试图显示快捷方式（.lnk）文件的真实路径（目标）。所以我在项目的corrent文件夹中复制并粘贴（test.lnk），我试图显示其目标

#include <windows.h>
#include <string>
#include <iostream>
#include <objidl.h>   /* For IPersistFile */
#include <shlobj.h>   /* For IShellLink */
#include "objbase.h"

using namespace std;


/*********************************************************************

*          lpszFilePath - string that will contain a file name
* Returns.......: S_OK on success, error code on failure

        wcsncpy(wszTemp, lpszShortcutPath, MAX_PATH);
#endif

        // Open the shortcut file and initialize it from its contents
        hRes = ppf->Load(wszTemp, STGM_READ);
        if (SUCCEEDED(hRes))
        {
            // Try to find the target of a shortcut,

                    return hRes;

                lstrcpyn(lpszFilePath, szPath, MAX_PATH);

            }
        }
    }

    return hRes;
}

int main(void)
{

    LPCTSTR lpszShortcutPath =("test.lnk");
    TCHAR szFilePath[MAX_PATH];

    HRESULT hRes =ResolveShortcut(lpszShortcutPath, szFilePath);
     cout << TEXT("Succeeded: path = ") <<hRes ;
    return 0;
}

显示Succeeded：path = -2134343

有人可以帮我显示.lnk文件的真实目标及其描述。

您可能忘了拨打CoInitialize

启动主要功能：

int main(void)
{
  CoInitialize(NULL);   //<< add

  LPCTSTR lpszShortcutPath....

  CoUninitialize();     //<< add
}

使用C ++显示（.lnk）快捷方式文件的实际路径
