I don't think what you described can be achieved. The most similiar design is what I said in the answer. For an example of Active Document, try opening a Word document (*.doc) from within Internet Explorer (Menu File/Open...).

Hi,

I didn't get the notifications until this morning.

>a transparent container successfully created and attched to some active window as child window

Does the active window belong to a seperate process (.exe)? Is it an OLE server or Automation server?

>i want this contaier window to scroll and update itself with that

What does the container display?

yes active window belongs to some other process .we dun have any info the the client(Active) window .but the container i'm attaching is OLE Server as well .

>i want this contaier window to scroll and update itself with that

>>> What does the container display?
container displays any thing ..basically in most of the cases some embedded controls ..

This is where the problem is. How can you update your window if you can't get any info from the active window? I don't see any ways.

hello ,

lets now take the problem like ..

i want to sync. the scroll bars of two applications . one already running app.
one written by me .

i'm thinking ..in all probability i might be wrong ...

Logic : whenever the other window is scrolled . its re-painted rite .it has to modify the display details ..i mean how much to scroll ( probably in pixels ..not relative to the size of the document ) .at the point from my app. i can use

PeekMessage() ..to get if that app. got the msg. WM_VSCROLL ..okey ..
then i can read the hDC of the window ..by calling GetWindowDC() ;

can i use that DC to make changes to my app. *i dun know i'm rite or not * ..

or something of that sort !!!

please see to it ..i'm really thankful to you for ur response .

P.S. i'm not worried abt. the points or something of that sort , in case u need more points ..even if my problem is not sorted out u ask for the points i'll give that ..

the only thing i want some way to solve this problem ..

thanks once again .

great regards ,

PeekMessage does not retrieve messages for windows that belong to other threads. In order to get the messages, you have to install a hook by using SetWindowsHookEx. This will slow down the system. To capture the content of the window, see

But I still think this way is not so elegant. The better way is to use OLE/Automation if possible.

P.S. Don't expect too much from me. I can provide limited help only due to my knowledge and time and the lack of your context.
