O.P. [help]Message notification
there's a couple of questions how do I know the hex value?
for example I looked at msdn for WM_MOVE and it says it is equal to &H3 what does that mean?.
and also to get HIWORD/LOWORD does
code:
WORD LOWORD(DWORD Value);
or
code:
WORD HiWORD(DWORD Value);
works?
and lastly at the Message Notification event what do I write at the if(Message==?)

&H3 is the Visual Basic way of displaying a hex value. &H3 is the equivalent of 0x3.

To get the hiword and lowords from a number use these

Javascript code:
/*
    Name:   lobyte
    Purpose:    Retrieves the lobyte from a value
    Parameters: w - the value to get the lobyte from
    Return: lobyte of the w parameter
*/

function lobyte(w){ return w & 0xff; }
 
/*
    Name:   hibyte
    Purpose:    Retrieves the hibyte from a value
    Parameters: w - the value to get the hibyte from
    Return: hibyte of the w parameter
*/

function hibyte(w){ return w >> 8; }
 
/*
    Name:   makeword
    Purpose:    Creates a WORD value by concatenating the specified values.
    Parameters: a - Specifies the low-order byte of the new value.
                b - Specifies the high-order byte of the new value.
    Return: The return value is a WORD value.
*/

function makeword(a,b){ return a | (b << 8); }



And for your last question you would do something like this

Javascript code:
function OnWindowEvent_MessageNotification(pPlusWnd, nMessage, wParam, lParam){
    switch(nMessage){
        case WM_MOVE:
            /*
                your code here
            */

    }
}

@matty: The two functions you posted there are for getting the low- and high-order bytes, not the low- and high-order words! A word consists of 2 bytes (16 bits), so you need to alter your functions a bit.
Javascript code:
function loword(n){ return n & 0xffff; }
function hiword(n){ return (n >> 16) & 0xffff; }
