As we all know,in GID plus, when we want to create a new font , we should do something like this :
FontFamily fontFamily(L"隶书");
Font font( &fontFamily, 24, FontStyleRegular, UnitPixel );
The problem is , the declare of this function is const WCHAR *, Maybe you will encount an compile error like this :
error C2664: '__thiscall Gdiplus::FontFamily::Gdiplus::FontFamily(const unsigned short *,const class Gdiplus::FontCollection *)' :
cannot convert parameter 1 from 'class CString' to 'const unsigned short *'
what if we want to create a new font with CString parameters like
CString strMyFontName;
FontFamily fontFamily(strMyFontName);
Just follow these steps to make it work:
CString strMyFontName("微软雅黑");
string fface=(string)strMyFontName;
WCHAR *wfface = new WCHAR[fface.length()+1];
if(!MultiByteToWideChar(CP_ACP,0,fface.c_str(),static_cast<int>(fface.length())+1,wfface,static_cast<int>(fface.length())+1))
{
TRACE0("Error creating text actor.");
}
else
{
FontFamily fontFmly(wfface);
Font font(&fontFmly, 12, FontStyleRegular, UnitPixel);
}
And don't forget to add include <string> in the top of the cpp file.
