推荐答案

好友，据我所知，您正在尝试将图像文件的内容复制到普通文件中，可以这样做...: )

但是，如果您尝试将一种文件转换为另一种类型，那么这样做是不正确的..

相反，您可以对程序员使用GDIPLUS: GDI + [ ^ ]

希望这会有所帮助！！！ :)

Buddy as per i understand your problem you are trying to copy content of image file to a normal file it is ok to do it...:)

But if you are trying to convert one kind of file to another type then it is not the right way to do so..

Instead you can use GDIPLUS for programmers: GDI+[^]

Hope this may help!!! :)

您显然正在使用MFC.为什么不继续使用框架的类?

You''re obviously using MFC. Why don''t you go ahead and use the framework''s classes?

CBitmap myBmp;
CImage myImg;
myImg.Attach(myBmp);
myImg.Save(_T("my.bmp"));
myImg.Detach();
