should interact with the system and with other DirectInput applications.

Set the cooperativity level to let DirectInput know how this device If( FAILED( hr = g_pdidMouse->SetDataFormat( &c_dfDIMouse ) ) ) DIMOUSESTATE structure to IDirectInputDevice::GetDeviceState. This tells DirectInput that we will be passing a controls on a device we are interested in, and how they should be Set the data format to “mouse format”. If( FAILED( hr = g_pDI->CreateDevice( GUID_SysMouse, &g_pdidMouse, NULL ) ) )

Obtain an interface to the system mouse device If( FAILED( hr = DirectInputCreate( hInst, DIRECTINPUT_VERSION, &g_pDI, NULL) ) ) to a IDirectInput interface we can use Register with the DirectInput subsystem and get a pointer HINSTANCE hInst = (HINSTANCE)GetWindowLong( hWnd, GWL_HINSTANCE ) IDirectInputDevice::SetCooperativeLevel Desc: Initialize the DirectInput variables using: Int winH, winW // Screen or window width and height LPDIRECTINPUTDEVICE g_pdidMouse // DirectInput Device interface LPDIRECTINPUT g_pDI // DirectInput Object HINSTANCE hInstance // Holds The Instance Of The Application HWND hWnd=NULL // Holds Our Window Handle HGLRC hRC=NULL // Permanent Rendering Context HDC hDC=NULL // Private GDI Device Context Global variables related to the app window //

NOTE: acquiring the mouse status via Windows Message Queue is slower thanĪcquiring it directly from the input device every time you redraw SwapBuffers(hDC) // Swap Buffers (Double Buffering) UpdateDirectInputState() // Take a look at the mouse status In the right place (see below example ***)ģ.- Call DestroyDInput upon Window destructionĥ.- Accomodate the UpdateDirectInputState function to changeĦ.- Enjoy the fastest way of acquire mouse status! When you draw the mouse pointer every frame it’ll be already Or transform the appropiate behavior of your program varsĤ.- Take into account the logical order of call to these functionsġ.- Call CreateDInput upon Window creation prior to initializeĢ.- Call UpdateDirectInputState before rendering the scene, so The current mouse position and Button statusģ.- Declaring DirectInput functions that do the job Including a nice struct of data that will keep up to date If U’re using the mouse capture routine and want to use a fast interface And actually i THINK that GetCursorPos is supposed to give you the current coordinate…but as to why it isn’t i don’t know. Ok to wrap things up, you check for the WM_MOUSEMOVE message and then use LOWORD and HIWORD on the lParam to get the x and y coordinates. This is inside the switch statement to handle messages

So for your purposes, the code might look like this: The y-position of the cursor is retrieved by: HIWORD(lParam) The x-position of the cursor is retrieved by: LOWORD(lParam) Īnd now if you want to know where the coordinates for the cursor are, you would get them like this: MK_RBUTTON Set if the right mouse button is down. MK_MBUTTON Set if the middle mouse button is down. MK_LBUTTON Set if the left mouse button is down. Ok, the wParam is going to contain the state of the mouse buttons. Whenever your mouse is moved, that message gets pushed on the stack. Ok in the WndProc procedure when you are handling each and every message you need to (like WM_CREATE, WM_QUIT, etc.), add in WM_MOUSEMOVE.

I don’t know glut so i don’t know how to answer your second question. Hey FredonMouse! Yup i agree with ya…people are pretty nice on this forum…that’s why i love posting here.
