Processing messages from WindowProc

[canderoc]

I'd like to be able to process messages from WindowProc function http://msdn.microsoft.com/en-us/library/...85%29.aspx, so I tried to piece together a function based on the AltMouseTriggers sample (which uses LowLevelMouseProc function). But it doesn't work. Any suggestions?

Function WinProcMessages

Code:

Copy      Help

function [nCode] [wParam] [CWPSTRUCT*m]

if(getopt(nargs)=0)
    int+ g_whook=SetWindowsHookEx(WH_CALLWNDPROC &WinProcMessages _hinst GetCurrentThreadId)
    opt waitmsg 1
    wait -1 -V g_whook
    ret

sel m.message
    case WM_LBUTTONDBLCLK
    out "double"

    case WM_MOVE
    out "move"
    
    case WM_SIZE
    out "size"

ret CallNextHookEx(g_whook nCode wParam m)

it works. To test, I replaced wait to mes. It shows these messages received by the message box.

sel m.message

,out "double"

,case WM_MOVE
,out "move"
;;;
,case WM_SIZE
,out "size"

ret CallNextHookEx(g_whook nCode wParam m)

I tested on Vista. If does not work, try to replace _hinst to 0.

Yes, some of the messages are processed but not the mouse messages for some reason.

if(getopt(nargs)=0)
,int+ g_whook=SetWindowsHookEx(WH_CALLWNDPROC &WinProcMessages 0 GetCurrentThreadId)

,if(!ShowDialog("diggy" 0)) ret
,ret

sel m.message
,case WM_NCLBUTTONDOWN
,out "WM_NCLBUTTONDOWN"

,case WM_LBUTTONDOWN
,out "WM_LBUTTONDOWN"

,case WM_NCHITTEST
,out "WM_NCHITTEST"
,if(m.lParam=HTBOTTOM)
,,out "HTBOTTOM"
,if(m.lParam=HTZOOM)
,,out "HTZOOM"

ret CallNextHookEx(g_whook nCode wParam m)

I'd like to get the WM_NCHITTEST messages for any active window. The code below seems to work better for this purpose, but is there a more efficient way?

Code:

rep
,0.1
,POINT p; xm(p)
,int ht=SendMessage(win WM_NCHITTEST 0 (p.x&0xffff)|(p.y<<16))
,sel ht
,,case HTBOTTOM out "HTBOTTOM"
,,case HTCAPTION out "HTCAPTION"

Mouse messages are posted (PostMessage), not sent (SendMessage). You need another type of hook (WH_...).

Don' know a better way than WM_NCHITTEST.
