How to send message to frame window ?
-
I wnat to send message to every active windows but I got a problem. If the window with child frame(like Word, Excel...etc.), it seems not to get the message which I send. Maybe it's useful to get every frames' handle and send message to every frame. Does anyone know how to get every handles of frames ?

- what message are you sending? 2) how are you currently sending it to all windows? 3) (prolly related to #1) how do you know they are not recieving the message?

All I want is to change the scroll lines number. I used SystemParameterInfo(SPI_SETWHEELSCROLLLINES,...) to change the scroll lines number but in the frame windows(like Word, Excel..etc), and then I send a WM_SETTINGCHANG message to system-wide windows. 'SendMessage(HWND_BROADCAST, WM_SETTINGCHANG, 0, 0)' But only in frame windows that this parameter don't work. What should I do?

First, i'm not certain that Office applications actually use this setting. I seem to remember at least Office '97 being a bit strange about handling the mouse wheel. What version of Office are you testing with? Second, you should be able to use the
SPIF_SENDCHANGEflag when callingSystemParametersInfo()to automatically sendWM_SETTINGCHANGEto all windows.- Shog9 -

Thanks for your help. I tested with Offce 'XP in Win98. It's really a little strange about the mouse wheel. I set 10 line per rotation but it does not work immediately only in the windows with frame windows(like Word, Excel..). In Explorer or Notepad, it works. If I close Word and launch agagin, this setting works. By the way, do you know 'SPI_SETSNAPTODEFBUTTON' parameter within SystemParametersInfo(). It seems not work in Win98. My code is : SystemParametersInfo(SPI_SETSNAPTODEFBUTTON, true, NULL, NULL)

SPIF_SENDCHANGEflag to the last parameter. I've never tried it though, so it could just be a bug in Win98.- Shog9 -
