Short video with goods source code , Double click to enlarge the relevant code when watching the video
1. Playing video DIALOG Get the current playback box

CRect curRect;
GetClientRect(&curRect);

2. Determine the current magnification required , Determine the length and width of the enlarged frame （z For multiple ）.

normalWidth = curRect.right;
normalHeight = curRect.bottom;
amplifyWidth = curRect.right * z;
amplifyHeight = curRect.bottom * z; else 
{
    
	if (point.x<normalWidth / 2*z)
	{
    
		if (point.y < normalHeight / 2*z || point.y>normalHeight - normalHeight / 2*z)
		{
    
			if (point.y<normalHeight / 2*z)
			{
    
				MoveWindow(0, 0, amplifyWidth, amplifyHeight);
			}
			else
			{
    
				MoveWindow(0, -(amplifyHeight - normalHeight), amplifyWidth, amplifyHeight);
			}
		}
		else
		{
    
			MoveWindow(0, -point.y * z+0.5*normalHeight, amplifyWidth, amplifyHeight);
		}
	}
	else if (point.x>normalWidth - normalWidth / 2*z)
	{
    
		if (point.y < normalHeight / 2*z || point.y>normalHeight - normalHeight / 2*z)
		{
    
			if (point.y<normalHeight / 2*z)
			{
    
				MoveWindow(-(amplifyWidth - normalWidth), 0, amplifyWidth, amplifyHeight);
			}
			else
			{
    
				MoveWindow(-(amplifyWidth - normalWidth), -(amplifyHeight - normalHeight), amplifyWidth, amplifyHeight);
			}
		}
		else
		{
    
			MoveWindow(-(amplifyWidth - normalWidth), -point.y * z+0.5*normalHeight, amplifyWidth, amplifyHeight);
		}
	}
else if (point.y<normalHeight / 2*z) 
{
    
	MoveWindow(-point.x * z+0.5*normalWidth, 0, amplifyWidth, amplifyHeight);
}
else 
{
    
	MoveWindow(-point.x * z+0.5*normalWidth, -(amplifyHeight - normalHeight), amplifyWidth, amplifyHeight);
}

3. At this point, the logical code is basically over . If you want to zoom in , And zoom in restore . Then put a layer on the outside if Judge .

if (isZoom==false)
{
    
isZoom=true;
········
}
else
{
    
	MoveWindow(0,0,normalWidth,normalHeight);
	isZoom = false;
}
