OnMouseMove message response problem (button not pressed)

Causes:

　　I originally wanted to use MFC to make a button that cannot be pressed (mouse moves over the button, the button will move away), use WM_MOUSEMOVE message to find

　　WM_MOUSEMOVE message is not sent to the parent window when the mouse is over the button

Solution:

　　Use the SetCapture () function to capture mouse messages

　　setCapture captures the following mouse events: onmousedown, onmouseup, onclick, ondblclick, onmouseover, and onmouseout

　　There is exactly the message we need to capture, but this function is a bit overbearing, and no other events can be done during the capture, so it needs to be released in time

　　Release using the ReleaseCapture () function

note:

　　The SetCapture () function seems to require the program to have administrator rights

{ 
	// TODO: add the message handler code and / or call the default value 
	CDialogEx :: OnMouseMove (nFlags, point); 

	// Set the mouse capture 
	SetCapture (); 

	/ / Get the position of the disagree button (relative to the upper left corner of the display) 
	CRect rect_disagree; 
	m_Disagree_Button.GetWindowRect (& rect_disagree); 
	// Get the position of the consent button 
	CRect rect_agree; 
	m_agree.GetWindowRect (& rect_agree); 
	// Get the position of the considered button 
	CRect rect_think; 
	m_think.GetWindowRect (& rect_think); 

	// Get the width and 
	height of the disagree button int height = rect_disagree.Height (); 
	int width = rect_disagree.Width (); 

	// Convert client coordinates to screen coordinates 
	ClientToScreen (& point); 

	/ / Determine whether the mouse is on the consent and consideration buttons
