点类未知 [英] Point class unkown

问题描述

嗯，我在长时间休息了Java之后最近又开始学习C ++.但是，我开始做一些想画点东西的程序，然后尝试使用DrawPolygon函数.但是，这需要一些要点，并且我的编译器总是以某种方式告诉我这是一个未声明的标识符.我觉得这是一个标准结构.用谷歌搜索后，它实际上在MSDN中，对我不起作用.设置VC 2010时我忘了包含某些内容还是忘了做?

谢谢大家(和gall徒)的所有帮助！

Well, I''ve recently took up C++ again after a long break to Java. But, I started to do some programming wanting to draw some stuff and I tried to use the DrawPolygon function. But, this requires some Points and somehow my compiler keeps telling me that it''s an undeclared identifier. I was under the impression that this was a standard struct. Having googled this, it is in fact in MSDN and it doesn''t work with me. Have I forgot to include something or is it something I forgot to do when setting up VC 2010?

Thanks for all the help in advance guys (and galls)!

推荐答案

用于绘制多边形的Windows 函数是

The Windows function for drawing polygons is Polygon[^].
You are probably talking about a method of a class.
(Are you using manged C++/CLI?)

嗯，谢谢！我仍然希望我的功能能正常工作(我会检查;))但是为了确定我会用你的！好吧，经过很多摆弄之后，我想我终于找到了使用POINT结构的方法！感谢您的帮助.

Ah, thanks! I still hope my function works (I''ll check ;) ) But I''ll use yours just to be sure! Well, after a lot of fiddling around, I think I''ve finally found my way to use the POINT-structure! Thanks for the help.
