clearTimeout on Mouse Exit

阅读更多关于 clearTimeout on Mouse Exit

问题 I have a timer setup like so: var timerID; $this.hover(function(){ $this.find('.stage_obj').each(function(index){ var current_obj = $(this); timerID = setTimeout(function(){ animate_on_top(current_obj, index);}, parseInt(OS.delay_y_on_set[index],10)); }); }, function(){ clearTimeout(timerID); }); There are functions to control the animation in/out on hover. The timers are acting as delays (.delay won't work in my situation). Everything works fine, except the timer isn't cancelled on mouse

阅读更多关于 Porting SetTimer() and KillTimer() to C#?

问题 I am trying to port some code from C++ to C#. I came across this in the C++ code: watchdogTimer = SetTimer(1,1000,NULL); ... KillTimer(watchdogTimer); What is this code doing, and how can this be ported to C#? Thanks. 回答1: The CWnd::SetTimer function you're looking at creates a timer that sends WM_TIMER events to the window. This is analogous to the System.Windows.Forms.Timer component in .NET.

Why would an integer property sometimes return a 0?

阅读更多关于 Why would an integer property sometimes return a 0?

问题 [Edit: I realized that the parameter that is failing is actually a double and not an integer. None of the integer timers fail according to the logs. Most of the timers and parameters are integers, but not all. Doubles are not atomic and the lack of locking may be the issue after all.] I have an application that uses a class that contains properties for configurable values. Most of the properties being used in the app are derived. The values are set at start up and not changed while the main
