ContributionsMost RecentMost LikesSolutionsRe: Delphi 2007: Cant get EnableProfiling to workHi! I tried your test project, and it was actually timed ok. The thing is, that the clock icon ("Enable Profiling") with the cross over never changes. From earlier versions of AQTime I expect that when EnableProfiling(True) is called, then the cross over the icon goes away, indicating that timing is on. When EnableProfiling(False) is called, then the cross comes back. So the problem is just that the icon doesn't change, it seems. Thanks for your help. Cheers JacobRe: Delphi 2007: Cant get EnableProfiling to workHi David, Initial Profiling Status for Threads is ON and the Enable Profiling button is OFF when I run the project. But calls to EnableProfiling() calls still have no effect. If I presse the Enable Prifiling button myslef, my code is profiled OK. Thanks Jacob Delphi 2007: Cant get EnableProfiling to workHi I use Delphi 2007 on a 64 bit Windows 7. I have installed the 64 bit version of AQTime 6.40. I try to start/stop the performance profiler from my Delphi code (32-bit) using EnableProfiling(True) ... EnableProfiling(False) defined in AQtimeHelpers.pas. but they have no effect. I can see, that the aqProf.dll isn't loaded or isn't found. I have checked the "Full check by routines". What else do I need to do? Thanks Jacob
