推荐答案
你必须用_T（）来阻止const字符串
例如，
You have to block const string with "_T()"
For example,
CreateFont( 24, 0, 0, 0, 700, FALSE, FALSE, FALSE, DEFAULT_CHARSET,
OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, DEFAULT_PITCH | FF_DONTCARE,
_T("Arial") );

Your question is directly related to that question. When you get some problem/error, start from here here, here or here. Just copy the error message and paste in the text box and click search.
And don't post a large amount of unrelated code here. That won't help. Just post the code which causes the error.
