kbmMW is the premiere n-tier product for Delphi, C++Builder and FPC on .Net, Win32, Win64, Linux, Java, PHP, Android, IOS, embedded devices, websites, mainframes and more. Next release of kbmMW further improves on the TkbmMWScheduler. The scheduler supports adding jobs to run given a quite extensive set of time conditions. It also already supports running jobs in the background, and when they are done, handle some foreground update of the GUI in a safe and consistent way.

However what if you want to run a number of jobs in parallel in the background and only call the job a success when all the background sub jobs has finished.

kbmMW will allow you to do that in a simple way in next release. Here is some example code.

One interesting part is the Run method, which now takes an array of procedures or functions to run. What happens internally, is that a scheduled event is defined, which in turn defines a number of child scheduled events that each process the given jobs.

Only when all jobs are done, the AfterRun method is executed.

Another interesting thing to notice, is that the AfterRun method can tap into data provided by any of the child events. In this case the child events time how long time they ran. The AfterRun method displays that, along with the total run time.

In this case, the total time is only slightly longer than the time for the longest running job because the jobs ran in parallel.

A few more fluent methods has also been added:

WithObject(AObject:TObject) and WithInterface(AInterface:IInterface) which allows you to tag on an object or an interface to an event. It could be used to provide data for the job, or to receive data from the job.

Only remember, that jobs are run multithreaded. Thus your object or interface must be threadaware.

Finally this example shows how a long running job should check for termination. Termination happens when the Terminate method is called on the running scheduled event, or when the scheduler is closing down, for example due to the application being shutdown.

kbmMW is a portable, highly scalable, high end application server and enterprise architecture integration (EAI) development framework for Win32, ..Net and Linux with clients residing on Win32, .Net, Linux, Unix, Mainframes, Minis, Embedded and many other places. It is currently used as the backbone in hundreds of central systems, in hospitals, courts, private, industries, offshore industry, finance, telecom, governements, schools, laboratories, rentals, culture institutions, FDA approved medical devices, military and more.
