it seems that there is still one problem left, which mentioned by logan, the new SDK still not become effective, for a constant defined in SDK 5.3 lead to compile error. i have remove the ojbect code of all targets and bring up to date all the targets, it still doesn't work:(
by the way, i upgrade the cw 9.0's sdk from 5.0 to 5.3 manually, by copying the corresponding files, but is seems that the precompiled header files didn't reflect such change, how to make it work? regards! -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
