How to make a paltalk program work all paltalk Versions?

Hey people this what I am wondering, how can I make a paltalk program work for all paltalk versions, This mostly affects the programs with chatsend function on them, for example this is the line we changing right now every time paltalk upgrades

atld = FindWindowEx(wtlsplitterwindow, 0&, "atl:004d0600", vbNullString)

So can something like this be done where you put the line code for each paltalk version one after another like this

atld = FindWindowEx(wtlsplitterwindow, 0&, "atl:004d0600", vbNullString)

atld = FindWindowEx(wtlsplitterwindow, 0&, "atl:004d6640", vbNullString)

And on the top of the command put like

On Error Resume Next
