simple for someone who knows but…
I have a form, within which is a tabbed section, when I click on a specific button I want it to open a specific tabbed page
HOW?
I found the answer, setfocus, you specify the page & area oin the page and tell it to set focus, easy realy. ho hum.
Glad I could help Damski 
To move thru the tabs you could also:
TabCtl0.Value = 0 for Tab 1
TabCtl0.Value = 1 for Tab 2 etc…
Typically setting the focus will work but make sure that the tab index is setup right, and all will work…otherwise I like:
TabCtl0.Value = 1 (Goes to tab 2) then I set focus on a field needing info…
Ok back to the regular channel!
