如何理解?Creating a Resource List
The following example creates a list of every resource in the Hand.exe file. The list is written to the Resinfo.txt file. The code demonstrates how to load the executable file, create a file in which to write resource information, and call the EnumResourceTypes function to send each resource type found in the module to the application-defined callback function EnumTypesFunc. See EnumResTypeProc for information on callback functions of this type. This callback function uses the EnumResourceNames function to pass the name of every resource within the specified type to another application-defined callback function, EnumNamesFunc. See EnumResNameProc for information on callback functions of this type. EnumNamesFunc uses the EnumResourceLanguages function to pass the language of every resource of the specified type and name to a third callback function, EnumLangsFunc. See EnumResLangProc for information on callback functions of this type. EnumLangsFunc writes information about the resource of the specified type, name, and language to the Resinfo.txt file. Note that the lpszType in EnumResTypeProc is either a resource identifier (ID) or a pointer to a string (containing a resource ID or type name); lpszType and lpszName in EnumResNameProc are similar. To use an enumerated resource, take the resource name or ID and call the appropriate function. For example, to load a string resource (RT_STRING), if lpszName in EnumResNameProc gives the resource ID (either directly or in a string that starts with the pound sign (#)), call LoadString. Otherwise, lpszName points to a string containing the resource name, so do the following: call FindResource or FindResourceEx with the resource name to get the resource handle;
call LoadResource with the resource handle to get the global handle;
call LockResource with the global handle to get a pointer to the resource data.

依msdn所说：to load a string resource (RT_STRING), if lpszName in EnumResNameProc gives the resource ID (either directly or in a string that starts with the pound sign (#)), call LoadString. Otherwise, lpszName points to a string containing the resource name, so do the following: 我读出的却不是，为什么？请大家看看用＃＃＃＃＃表示的代码。

//######################################################
// 为什么这儿得不到正确的id.？？？？？？？？？？？？
//
//######################################################
此处读取的是资源的名称，而不是ID，

请问 yndfcd(YNDFCD)：如何得到资源id?您说的对，我发现我紧接着用方法：
1。call FindResource or FindResourceEx with the resource name to get the resource handle;
2。call LoadResource with the resource handle to get the global handle;
3。call LockResource with the global handle to get a pointer to the resource data
得到了数据，它是unicode格式，每一段前面都有一些0字符，如何知道它的结构？还有我发现它的lpName和真实的resource id似乎有关系。但这些数据里没有resource id, 为什么？请问各位大师：lpName由谁决定，是编译器吗？与resource id有关吗？

我有一个办法！很有用，我自己也是这么做的！
并不要什么高深的PE格式！只需看看就会了！
1：我们先用VC把DLL或EXE文件打开（以资源编辑的形式打开），并找出你要获取的资源的ID号，并记下！
2：在你的代码中用LoadLibrary(DLL或EXE) 来获得句柄，然后再用LoadString, LoadCursor,LoadImage 等等的函数去得到你要的资源！
这不是很简单吗？下面是我刚才做的例子：我要从test.exe中得到字符串资源。于是我用VC把test.exe打开，得到ID号是101和102两个。
于在我的代码中将这样的取资源：
#include "stdafx.h"
#include <windows.h>
#include <iostream.h>#define STR1 101
#define STR2 102char *filename="test.exe";
int _tmain(int argc, _TCHAR* argv[])
{
HMODULE m_h=::LoadLibrary(filename);
char *pstr = new char[50];
if (m_h!=NULL)
{

int m_size=LoadString((HINSTANCE)m_h,STR1,pstr,50);
if( m_size>0 )
{
cout<<pstr<<endl;
}
else
{
cout<<"failed LoadString"<<endl;
}
}else
{
cout<<"LoadLibrary failed"<<endl;
}
return 0;
}大家不妨去试一试！

资源"ID"是一个DWORD或者LPCSTR，如果最高位为1表明这是一个序号，把最高位的1去掉，再用LoadResource((LPCSTR)ID)就可以找到它；如果最高位是0，表明它是一个LPCSTR

你只要看一看资源的二进制格式的说明就知道了，资源的前面是一个入口，它由一个header和存放的数据组成。一个资源入口的内容如下：
   A DWORD that contains the size of the resource header
   A DWORD that contains the size of the resource data
   The resource type
   The resource name
   Additional resource information
由于LockResource将指针直接指向了Additional resource information所以得不到name和ID。可以直接读资源文件到得到ID。不过MSDN上没有介绍，可能要找一些非正式文档。
参看MSDN：Win32 Resource File Formats

衷心祝愿各位帮我的人长命百岁！ To jiagh(无会): 这种办法不是我想要的。我的问题是发现一些工具（包括VC）都可以读到resource id,而调用这些api则不行。DoItFreely(Freely)，yndfcd(YNDFCD)说的有道理，我再去试试。等这个问题解决了，我一定写篇FAQ来报答各位的帮助！

函数
EnumResourceLanguages / EnumResourceTypes / EnumResourceNames回调
BOOL CALLBACK EnumResNameProc(
  HMODULE hModule,   // module handle
  LPCTSTR lpszType,  // resource type
  LPTSTR lpszName,   // resource name
  LONG_PTR lParam    // application-defined parameter
);回调函数返回的 lpszName 有几种情况：
1、(lpszName  & 0xFFFF0000) == 0 即 (UINT)lpszName < 65536 则
Resource Id = (UINT)lpszName;2、否则，lpszName 指向一个 String , 如果 lpszName[0] == _T("#") 且 lpszName[1] 以后完全为数字，如 "#1024" ，则
Resource Id = _ttoi(&lpszName[1]); // "#1024" --> id = 10243、此时该资源没有 id ，仅有名称 lpszName
