Hey Kamen, I tried this really quick in python and it worked to toggle the button:
win32api.PostMessage(0x0001085E, win32con.WM_LBUTTONDOWN, win32con.MK_LBUTTON, 0x000A000A) win32api.PostMessage(0x0001085E, win32con.WM_LBUTTONUP, win32con.MK_LBUTTON, 0x000A000A) I used Spy++ to grab the window handle of the button (0x0001085E) and gave it some arbitrary coordinates of (10, 10) (0x000A000A) which are inside the button's client rect. To get the state of the button, this works: buttonState = win32api.SendMessage(0x0001085E, win32con.BM_GETSTATE, 0, 0) if buttonState & win32con.BST_CHECKED: print "Button is pressed." else: print "Button is not pressed." You should be able to do the same from C++. Obviously you'll need to actually find the window handle for the button but that should be pretty easy - it's a great-grandchild of the a window called "DS_ChildRender Preview" with window class "AfxWnd90u". Hope this helps! -Nicolas On Fri, May 18, 2012 at 8:33 AM, Kamen Lilov <[email protected]>wrote: > Hello, > > I'm looking for an undocumented feature :) - in the SI preview window, > there is a Lock button that will cause SI to stop sending any further > Render requests (for that preview) until the button is toggled again. > > Is there a way to programatically access, and change, the value of this > toggle?
