PE文件资源解析（七）manifest资源的解析

mainfest资源，在这里指的是资源类型为RT_MANIFEST的资源信息。通过ResHacker看到的效果图如下：

manifest资源存储编码格式是UTF-8（开始3个字节是EF BB BF），解析代码如下：

// UTF8-EF BB BF
HRSRC hResrc = ::FindResourceEx((HMODULE)hModule, lpType, lpName, wLanguage);
DWORD dwSize = ::SizeofResource((HMODULE)hModule, hResrc);
HGLOBAL hGlobal = ::LoadResource((HMODULE)hModule, hResrc);
if (hGlobal == NULL)
	return;

BYTE* lpResrc = (BYTE*)LockResource(hGlobal);
if (lpResrc == NULL)
	return;

HGLOBAL hAllocMem = GlobalAlloc(GMEM_FIXED, dwSize);
char* pMem = (char*)GlobalLock(hAllocMem);
memcpy(pMem, lpResrc, dwSize);
short length = dwSize;
char* pBuffer = new char[length + 1];
memset(pBuffer, 0, length + 1);
memcpy((char*)pBuffer, (char*)pMem, length);
std::string sResult = Utf8ToGB2312(&pBuffer[3]);
delete[] pBuffer;
GlobalUnlock(hAllocMem);
GlobalFree(hAllocMem);
//sResult就是manifest资源的内容

这里用到了一个UTF8字符串转换函数，代码如下：

//UTF-8到GB2312的转换
std::string Utf8ToGB2312(const char* utf8)
{
	int len = MultiByteToWideChar(CP_UTF8, 0, utf8, -1, NULL, 0);
	wchar_t* wstr = new wchar_t[len];
	memset(wstr, 0, len);
	MultiByteToWideChar(CP_UTF8, 0, utf8, -1, wstr, len);
	len = WideCharToMultiByte(CP_ACP, 0, wstr, -1, NULL, 0, NULL, NULL);
	char* gb2312 = new char[len];
	memset(gb2312, 0, len);
	WideCharToMultiByte(CP_ACP, 0, wstr, -1, gb2312, len, NULL, NULL);
	std::string result = std::string(gb2312);
	if (wstr) delete[] wstr;
	if (gb2312) delete[] gb2312;
	return result;
}
