If you develop a webpart and present it to a Sharepoint website, Sharepoint creates a top-level scope. In this scope, Sharepoint adds a monitor named spcriticaltracecounter to it, this monitor can be used to insert information to the assert and critical events segments of developer dashborad. For example: If you click the link on the left of the Information bar, you can get more information about the recorded event (the call stack of the current eve

We often need to perform a certain task on a regular basis, and we can use timers in languages such as C + +,But in Python, the standard library gives us two ways of Timer and Sched.First of all, say Sched module, exactly, it is a scheduling (delay processing mechanism), each time you want toRow a task must write a schedule. Use the following steps:1. Generating the Schedulers = Sched.scheduler (Time.time,time.sleep)Python timed events Timer Sched
