c++builder E2015 Ambiguity between ‘Gdiplus::Graphics::Graphics(void *)’ and ‘Gdiplus::Graphics::Graphics(void *,int)’

加了Gdiplus.h后，编译不能通过，提示[C++ Error] GdiplusGraphics.h(37): E2015 Ambiguity between ‘Gdiplus::Graphics::Graphics(void *)’ and ‘Gdiplus::Graphics::Graphics(void *,int)’

这个是CodeGear提到的一个已知问题：

Must Turn off NO_STRICT #define with GdiPlus library

The C++ library GdiPlus cannot be used in non STRICT mode, since it requires that Graphics::Graphics(HDC) be distinguishable from Graphics::Graphics(HWND). In non STRICT mode, both HWND and HDC are “void*”. Otherwise, you get the error:
[C++ Error] GdiplusGraphics.h(37): E2015 Ambiguity between ‘Gdiplus::Graphics::Graphics(void *)’ and ‘Gdiplus::Graphics::Graphics(void *,int)’

解决办法就是在Project->Options里的Paths and Defines的Conditional Defines里面加上STRICT，这样就开启了STRICT模式，那个歧义就可以消除了！

我的环境是2006,

1、加入头文件

#include <Gdiplus.h>

2、加入预编译命令

#pragma link "gdiplus.lib"

3、option->c++ compling->paths and defines里的conditional defines 里加上 STRICT

就ok了
