findfirstfile函数调用成功返回文件信息却总会报一个错误

[xingger]

比如写下面一段简单代码：

int main(int argc, char* argv[])
{
char *fileName="E:\\APP01\\*.txt";
WIN32_FIND_DATA wfd;
HANDLE hFirstf=::FindFirstFile(fileName,&wfd);
if(INVALID_HANDLE_VALUE==hFirstf)
{
MessageBox(NULL,"失败！","提示",MB_OK);
return FALSE;
}
printf("%s\n",wfd.cFileName);
::CloseHandle(hFirstf);

printf("%d",GetLastError());
return 0;
}

文件信息也能成功获得，但总提示句柄无效是何问题啊，请大家给指点一下

LastError是上次错误的错误码，调用成功时不会把这个值设置为0，所以当函数没有返回失败时调用GetLastError是没有意义的。

不是那问题，不过还是谢了，关注，请大虾指点一下~~~

The FindFirstFile function opens a search handle and returns information about the first file whose name matches the specified pattern. It searches both the long and short file names. After the search handle has been established, use the FindNextFile function to search for other files that match the same pattern. When the search handle is no longer needed, close it by using the FindClose function.
