Duilib编译遇见提示说未定义的HANDLE hFile，将红色字体部分移动到CreateFile后面就不再报错了，什么原因？使用的是Win7和VS2017

[沐铭jff]

while (!pData)
{
//读不到图片, 则直接去读取bitmap.m_lpstr指向的路径
HANDLE hFile = ::CreateFile(pstrGifPath, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, \
FILE_ATTRIBUTE_NORMAL, NULL);
if( hFile == INVALID_HANDLE_VALUE ) break;
dwSize = ::GetFileSize(hFile, NULL);
if( dwSize == 0 ) break;

DWORD dwRead = 0;
pData = new BYTE[ dwSize ];
::ReadFile( hFile, pData, dwSize, &dwRead, NULL );
::CloseHandle( hFile );

if( dwRead != dwSize ) {
delete[] pData;
pData = NULL;
}
break;
}
if (!pData)
{
return NULL;
}

Gdiplus::Image* pImage = LoadGifFromMemory(pData, dwSize);
delete[] pData;
return pImage;
}
