Sorry for delayed response! Usually such result means that the SetView function spends the rest of the time (100%-29.72%) doing something else (e.g. not calling other functions and doing some math calculations for instance). If you have source code for that function, you can install dotTrace 4.5.1 and use the Line-by-line profiling feature to find out exactly what that function is doing. Thank you!
