Approach for VB scripting in testcomplete

Recording scripts is way to start but would not be practicaly usefull since there could be many varince.
as one of TC thred says a robust script frame work would be 70% error handling and 30% actual testing.
My advices are
1) start with simple/most used/ small functionality
2) TC has good documentations read when ever problem comes
3) often visit this forum and ask, search-there are lot of usefull information (seems you are..)
4) try to build reusedble library (eg common stuff like navigation )
5) there cold be many pillfalls in name-mapping, understand the concept, read threds and find the best way for you
6) some time it may take a while to master, anticipate that

good luck..!
