Subclassing an OCX

[Torben Marcussen]

Thanks for your replys.

I have managed to solve my problem with the following code:

CallBack Function DlgProc
   Select Case CbMsg
      Case %WM_INITDIALOG
         RetMouseHook = SetWindowsHookEx(%WH_MOUSE, CodePtr(MouseHook), 0, GetCurrentThreadId)
      Case %WM_DESTROY: UnhookWindowsHookEx RetMouseHook
   End Select
End Function


Function MouseHook(ByVal iCode As Integer, ByVal wParam As Long, ByVal lParam As Long) As Dword

   Static LButtonDown as long
	
   If iCode = %HC_ACTION Then
      Select Case wParam
         Case %WM_LBUTTONDOWN
            LButtonDown = %True
         Case %WM_LBUTTONUP
            LButtonDown = %False
         Case %WM_MOUSEMOVE
            if LButtonDown = %True then
               SendMessage hDlg, %WM_NCLBUTTONDOWN, %HTCAPTION, BYVAL %NULL
            end if
      End Select
   End If
   Function = CallNextHookEx(RetMouseHook, iCode, wParam, lParam)

End Function

Torben,

I would suggest to set a hook on the OCX parent window
and monitor the WM_SETCURSOR messages it receives...

Torben,

JAZZAGE has several callback functions you could use to have greater
control on what is going on.

Example:

       CALL JACreateControl(hCTL&, "Content", _
                            jX&, jY&, jW&, jH&, _
                            "ProgID:Shell.Explorer.2;JARTKEY:Elwz6A-99AC5-951AG-6CE52-9", _
                            1, pWebContent???)

       IF pWebContent??? THEN
          CALL JASetControlResizeStyle(pWebContent???, %JAHANDLE_PUNK, %JARESIZESTYLE_X2RIGHT OR %JARESIZESTYLE_Y2BOTTOM)
          CALL JASubscribeEvents(pWebContent???, [b]CODEPTR(JAContentCallBack)[/b], 1)
       END IF

Hi all,

I was wondering if someone can tell me how to subclass an
OCX created with the JACOM dll..???

Specifically, I have added a Flash movie on a form using JA
and I now want to be able to move the form by clicking on the
Flash movie and dragging...

TIA
Torben
