>Visual MaxFrame comes with a hacking tool to make retrofitting apps easier, if still not a joy. This tool opens a selected .vcx or .scx as a grid and guides the changes that need to be made to change class and library names, even making bulk changes (e.g. change all txtbox with mytxtbox). Version 4 is just being released, I think it is worth a look.

Thanks Reg, I will take a look at it!
