Regardless of whether you are knee high in PCs I am certain you should have utilized PaintBrush. It gives an office to draw a freehand drawing utilizing mouse. Allow us to check whether we also can accomplish this. We can demonstrate where the freehand drawing starts by tapping the left mouse button. Then, at that point, as we move the mouse on the table with the left mouse button discouraged the freehand drawing ought to get attracted the window. This drawing ought to go on till we don't deliver the left mouse button. The mouse input comes as messages. With the expectation of complimentary hand attracting we want to handle three mouse messages- WM_LBUTTONDOWN for left button click, WM_MOUSEMOVE for mouse development and WM_LBUTTONUP for delivering the left mouse button. Let us presently perceive how these messages are handled for drawing freehand. The Allow us now to examine each mouse controller. When the WM_LBUTTONDOWN message shows up the WndProc( ) work calls the controller OnLButtonDown( ). At the same time, we have passed the mouse facilitates where the snap happened. These directions are gotten in lParam in WndProc( ). In lParam the low request 16 pieces contain the present x - direction of the mouse though the high request 16 pieces contain the y - coordinate. The LOWORD and HIWORD macros have been used to isolate out these x and y - facilitates from lParam. In OnLButtonDown( ) we have protected the beginning stage of freehand in worldwide factors x1 and y1. Whenever OnMouseMove( ) gets called it really looks at whether the left mouse button stands discouraged. In the event that it stands discouraged, the banners variable contains MK_LBUTTON. On the off chance that it does, the current mouse facilitates are set up in the worldwide factors x2, y2. A line is then drawn between x1, y1 and x2, y2 utilizing the capacities MoveToEx( ) and LineTo( ). Next time around x2, y2 ought to turn into the beginning of the following line. Thus the present upsides of x2, y2 are put away in x1, y1. Note that here we have acquired the DC handle utilizing the API work GetDC( ). This is on the grounds that we are completing the attracting action response to a message other than WM_PAINT. Additionally, the handle acquired utilizing GetDC( ) ought to delivered use a call to ReleaseDC( ) work. You can have a go at utilizing BeginPaint( )/EndPaint( ) in mouse controllers also, GetDC( )/ReleaseDC( ) in OnPaint( ). Would you be able to draw any ends? Catching the Mouse If during the time spent drawing the freehand the mouse cursor goes outside the client region then the window underneath our window
