Any Good Iedas for a skin? Or a good idea of how?

Ok, after a bit of poking around, I have foud that Vista LogonUI through another DLL gets its graphic resources through another DLL called imageres.dll I am wondering if it is at all possable to (for lack of a better term) "hijack" the call into imageres.dll for a specific resource, and have it routed to another dll (My apps dll) for a resource of the same name but with different content.

Windows Mobile 6 Pro. Anybody know how to make skins for this? Specifically I want to skin the phone dialer pad. I can use C++ if neccesary but would prefer to do it in C#.

Count you not just set the AllowUsertoAddRows property of the datagrid to false?
