在C ++ win32中捕获鼠标指针 [英] Capture mouse pointer in C++ win32

问题描述

我已将此代码编写为捕获屏幕，它可以100％工作，但它不会捕获鼠标指针



i希望它也能捕获鼠标指针



我的代码如下所示

 #includestdafx.h
 #includescreenshot2.h
 #include< Windows.h> 
 #include< stdio.h> 
 
 void ScreenShot（）{
 int x1，y1，x2，y2，w，h; 
 
 //获取屏幕尺寸
 x1 = GetSystemMetrics（SM_XVIRTUALSCREEN）; 
 y1 = GetSystemMetrics（SM_YVIRTUALSCREEN）; 
 x2 = GetSystemMetrics（SM_CXVIRTUALSCREEN）; 
 y2 = GetSystemMetrics（SM_CYVIRTUALSCREEN）; 
 w = x2  -  x1; 
 h = y2  -  y1; 
 
 //将屏幕复制到位图
 HDC hScreen = GetDC（NULL）; 
 HDC hDC = CreateCompatibleDC（hScreen）; 
 HBITMAP hBitmap = CreateCompatibleBitmap（hScreen，w，h）; 
 HGDIOBJ old_obj = SelectObject（hDC，hBitmap）; 
 BOOL bRet = BitBlt（hDC，0,0，w，h，hScreen，x1，y1，SRCCOPY）; 
 
 //将位图保存到剪贴板
 OpenClipboard（NULL）; 
 EmptyClipboard（）; 
 SetClipboardData（CF_BITMAP，hBitmap）; 
 CloseClipboard（）; 
 
 //清理
 SelectObject（hDC，old_obj）; 
 DeleteDC（hDC）; 
 ReleaseDC（NULL，hScreen）; 
 DeleteObject（hBitmap）; 
 
} 
 
 int APIENTRY wWinMain（_In_ HINSTANCE hInstance，
 _In_opt_ HINSTANCE hPrevInstance，
 _In_ LPWSTR lpCmdLine，
 _In_ int nCmdShow）
 {
 ScreenShot（）; 
返回0; 
} 

我的尝试：



只使用GetCusorPos（）尝试我不知道实现它的实际方法

解决方案

参见使用鼠标输入| Microsoft Docs [ ^ ]

i have written this code to capture screen, it works 100% but it does not capture the mouse pointer

i wanted it to capture the mouse pointer as well

My code looks like this

#include "stdafx.h"
#include "screenshot2.h"
#include <Windows.h>
#include <stdio.h>

void ScreenShot() {
	int x1, y1, x2, y2, w, h;

	// get screen dimensions
	x1 = GetSystemMetrics(SM_XVIRTUALSCREEN);
	y1 = GetSystemMetrics(SM_YVIRTUALSCREEN);
	x2 = GetSystemMetrics(SM_CXVIRTUALSCREEN);
	y2 = GetSystemMetrics(SM_CYVIRTUALSCREEN);
	w = x2 - x1;
	h = y2 - y1;

	// copy screen to bitmap
	HDC     hScreen = GetDC(NULL);
	HDC     hDC = CreateCompatibleDC(hScreen);
	HBITMAP hBitmap = CreateCompatibleBitmap(hScreen, w, h);
	HGDIOBJ old_obj = SelectObject(hDC, hBitmap);
	BOOL    bRet = BitBlt(hDC, 0, 0, w, h, hScreen, x1, y1, SRCCOPY);

	// save bitmap to clipboard
	OpenClipboard(NULL);
	EmptyClipboard();
	SetClipboardData(CF_BITMAP, hBitmap);
	CloseClipboard();

	// clean up
	SelectObject(hDC, old_obj);
	DeleteDC(hDC);
	ReleaseDC(NULL, hScreen);
	DeleteObject(hBitmap);

}

int APIENTRY wWinMain(_In_ HINSTANCE hInstance,
	_In_opt_ HINSTANCE hPrevInstance,
	_In_ LPWSTR    lpCmdLine,
	_In_ int       nCmdShow) 
{
	ScreenShot();
	return 0;
}

What I have tried:

Tried using GetCusorPos() only i dont know the actual method to have it implemented
