Delphi - Chrome Tabs

I currently have a code in Delphi that looks for opened session of Chrome. If exists, brings to front. Otherwise, open a Chrome session. All this is done. What I still need is: Chrome may have more than on opened browser tab. If so, I'm not able to see it on Windows Process List. What I would need to be developed is one of these two situations: 1) use send message to Google Chrome to change its current tab in such way I can evaluate if new tab is the one I'm expecting 2) list all tabs description related to its handle in such way I can bring to front. The problem I'm currently facing without this development is: I only can see current Google Chrome tab. If desired tab is opened but not the active one I'm not able to see and consequently I do open one more. Development must be done to DELPHI 5. Regards, Evandro
