推荐答案

打印屏幕Alt + PrnScr始终适用于控制台应用程序。你做错了什么;或者你的操作系统坏了。



基本上，你是通过 getimage（int left，int top，int right，int bottom，void *）来实现的位图），请参阅：

另外一个问题是如何获取控制台窗口的范围。在这里你需要使用 include< windows.h> 。



特别是你可以假设正在执行屏幕截图代码，或者您可以获得桌面上所有窗口的屏幕截图，或使用其他一些选择标准。您将需要以下一些Windows API函数：

最后一个 GetWindowRect 最终给你的尺寸/调用 getimage 所需的位置参数。

Print screen Alt+PrnScr always works on console applications. You are doing something wrong; or your OS is broken.

Basically, you do it through getimage(int left, int top, int right, int bottom, void *bitmap), please see:
http://www.programmingsimplified.com/c/graphics.h/getimage[^].

Additional problem is how to get the extents of the console window. Here you need to use include <windows.h> as well.

In particular, you can assume that the screenshot code is being executed or you can get screen shot of all windows on the desktop, or use some other selection criteria. You will need some of the following Windows API functions:

http://msdn.microsoft.com/en-us/library/windows/desktop/ms633504%28v=vs.85%29.aspx[^],
http://msdn.microsoft.com/en-us/library/windows/desktop/ms633505%28v=vs.85%29.aspx[^],
http://msdn.microsoft.com/en-us/library/windows/desktop/ms633515%28v=vs.85%29.aspx[^],
http://msdn.microsoft.com/en-us/library/windows/desktop/ms633519%28v=vs.85%29.aspx[^].

The last one GetWindowRect ultimately gives you the size/position parameters you need for a call to getimage.

可能是你可以使用getpixel函数并创建一个位图并保存到磁盘。它并不难。

may be you can use getpixel function and create a bitmap and save to disk. it is not that hard.

你可以在C ++的输出窗口中使用ALT + ENTER，然后你将全屏显示。

之后你可以使用Printscreen然后粘贴到mspaint。



它会起作用!!!!!!

You can use ALT + ENTER from output window of C ++ then you will come out of full screen.
After that you can use "Printscreen" and then paste in mspaint.

It will work !!!!!!
