How to change AVI in dialog (from resource file)

[Dave Biggs]

Credit should go to Lance - it's a technique suggested in one of his posts.
Oh, and Borje too (for POFFS) of course

[Michael Mattias]

That's a clever solution. I like that.

Dave, thanks!
It works fine.

Here's a way without subclassing..

 
#Compile Exe
#Include "WIN32API.INC"
#Include "COMMCTRL.INC"
 
%IDC_SYSANIMATE32_1 = 101
'------------------/
 
 CallBack Function DlgProc()
  Local Rct As RECT
    Select Case CbMsg
     Case %WM_LBUTTONDOWN
        GetClientRect GetDlgItem(CbHndl, %IDC_SYSANIMATE32_1), Rct
        If PtInRect(Rct, LoWrd(CbLParam), HiWrd(CbLParam)) Then
          Dialog Set Text CbHndl, "Mouse click"
        End If
      Case %WM_LBUTTONDBLCLK
        GetClientRect GetDlgItem(CbHndl, %IDC_SYSANIMATE32_1), Rct
        If PtInRect(Rct, LoWrd(CbLParam), HiWrd(CbLParam)) Then
          WinBeep 800, 50
          Dialog Set Text CbHndl, "Mouse double-click"
        End If
 
      Case %WM_COMMAND
        Select Case CbCtl
          Case %IDC_SYSANIMATE32_1
            Select Case CbCtlMsg
              Case %ACN_STOP
                Dialog Set Text CbHndl, "stop"
              Case %ACN_START
                Dialog Set Text CbHndl, "start"
              Case Else
                Dialog Set Text CbHndl, Format$(CbCtlMsg)
            End Select
        End Select
    End Select
End Function 
'------------------/
 
Function PBMain()
 Local hDlg, hCtl As Dword
  Call InitCommonControls
 
  Dialog New Pixels, 0, "", 300, 200, 400, 400, %WS_POPUP Or %WS_CAPTION Or %WS_SYSMENU, To hDlg
  Control Add "SysAnimate32", hDlg, %IDC_SYSANIMATE32_1, "", 10, 10, 320, 320, _
      %WS_CHILD Or %WS_VISIBLE Or %ACS_CENTER 'OR %ACS_TRANSPARENT
  Control Handle hDlg, %IDC_SYSANIMATE32_1 To hCtl
 
  Animate_Open hCtl, "c:\windows\clock.avi"    '%ACM_OPEN
  Animate_Play hCtl, 0, -1, 1                  '%ACM_PLAY
 
  Dialog Show Modal hDlg, Call DlgProc
 
End Function 
'------------------/

I don't see in the doc where the animation control sends a click notification via WM_NOTIFY or any other way.

An animation control can send two notification messages, ACN_START and ACN_STOP, to its parent window. Most applications do not handle either notification.

You may have to subclass the control to pick off WM_RBUTTONUP or something like that.

Hello, Michael,
how to receive the message from SysAnimate32 control (for user clicks or double-clicks)?

I try with:

CASE %WM_NOTIFY
	  pNMHDR = CBLPARAM
	  IF @pNMHDR.idFrom = %IDC_SYSANIMATE32_1 AND @pNMHDR.code = %NM_CLICK THEN ...

..but without success

Thanks

Michael, thanks!
It's works and without %ACM_CLOSE ??, but with %ACM_STOP

CONTROL SEND hDlg, %IDC_SYSANIMATE32_1, %ACM_STOP, 0, 0
CONTROL SEND hDlg, %IDC_SYSANIMATE32_1, %ACM_OPEN, 0, dwDlgAvi

dwDlgAvi -> %IDRC_AVIFILE1, %IDRC_AVIFILE2 ...

[Michael Mattias]

From the doc it looks like you can just send ("CONTROL SEND") ACM_CLOSE message to stop current clip, and ACM_OPEN to start a new one.

Failing that, I don't see why you couldn't just destroy that control and recreate it with a different clip.

I have in resource file 2 x AVI defined:

my_avi1       AVI    "test1.AVI"
my_avi2       AVI    "test2.AVI"

How to replace/change AVI, for example from my_avi1 to my_avi2 in:

CONTROL ADD "SysAnimate32", hDlg, %IDC_SYSANIMATE32_1, "my_avi1", 6, 6, 24, 24, _
                            %WS_CHILD OR %WS_VISIBLE OR %ACS_CENTER OR %ACS_TRANSPARENT OR %ACS_AUTOPLAY

It is possible to make it with SetDlgItemInt or SendMessage?
..but how?

Thanks
