操作剪切板的问题

C/C++ code

char szFilePath[] = "c:\\1.exe";if(OpenClipboard(NULL))    {        HANDLE hClip = GlobalAlloc(GMEM_ZEROINIT, strlen(szFilePath) + 1);        char* lpData = (char*)GlobalLock(hClip);        strcpy(lpData, szFilePath);        GlobalUnlock(hClip);        EmptyClipboard();        SetClipboardData(CF_HDROP, hClip);        CloseClipboard();    }

执行了这几句之后按ctrl+v后explorer就不响应了，求解。
调试了几次了，各个API的返回值都没什么问题
求大神指点！
