新问题：关于GDI＋提示Ambiguity between 'Graphics' and 'Gdiplus::Graphics'的，请教高手

[wys512]

按照下边的做法却出现后边描述的情况，请各位给个解决方案，谢谢
==================================================
#include <algorithm>
using std::min;
using std::max;
#include <Gdiplus.h>

#include <Classes.hpp>
#include <Controls.hpp>
#include <StdCtrls.hpp>
#include <Forms.hpp>
#include <ExtCtrls.hpp>
using namespace Gdiplus;

象这样排列包含文件就行了
======================================================


#include <algorithm>
using std::min;
using std::max;
#include <Gdiplus.h>
的前边又会自动添加
#include <Classes.hpp>
#include <Controls.hpp>
#include <StdCtrls.hpp>
#include <Forms.hpp>
#include <ExtCtrls.hpp>
#include <Graphics.hpp>------主要是这个，因为我用了speedbutton
或者使用了image装载jpeg的话就会报这个错：Ambiguity between 'Graphics' and 'Gdiplus::Graphics'

然后编译仍然通不过，请问该如何解决呢
/////////////////////////////////////////////////////////////////
可以重新定义一下,比方说
typedef Gdiplus::Graphics GpGraphics-------找到这个方法，但不知添加在哪个地方合适。。。。。。

在引用Graphics.hpp的类时加上::Graphics，如：

::Graphics::TBitmap *bmp = new ::Graphics::TBitmap();

[wys512]

这样可行吗

[wys512]

我的情况不是说引用TBitmap时出错，而是引用了象speedbutton这样的内含了<Graphics.hpp>时出现的问题

[阿发伯]

你说的问题使用域操作符::可以解决的，我刚才试了，引用speedbutton这样的内含了<Graphics.hpp>没有出错

[wys512]

好的，我回去试下先，可以的话明天结贴，呵呵，如果不行，明天可能还要麻烦下你哦

[阿发伯]

下面这个例子和你的包含是一样的，还加了TDpeedButton和TImage，都没有错误
