hi All

Env: MFC visual studio6.0, win xp

I've been trying to autoit some of our legacy code written in MFC - an SDI app, which has got a number of tabs and some tabs got a splitter control

and has got a list view control in it. I can see its ids/handles autoit info or using UI spy tool but when I tried to get the handle of a list view

I get 0 return value (see the attached image for the tree structure of controls identified by the ui spy). I have tried a number of ways to get it, but no use

even tried _WINAPI_ function to enumerate the windows and I can see autoit returns the handle value. I used it in listview function to get the number of items

in the list views view - still no good. :blink: . This is the case of some of the controls in the AfxFrameOrView42 control. I can get automate some of the controls in

some other tabs like edit and button controls. only problem is in control sin frameorview . Any ideas gurus???? any help will be really appreciated ...

(sorry if u dont understand my problem, I'll explain it in detail, thanks in advance)

regards

Hi Sir,

Thanks very much for your reply....

I have managed to get the list view count by getting the handle of the control using _WinAPI_EnumWindows and thensending

a send message call to the control handle - your tips helped me to look into the win API calls and it workd.

cheerio all the best
