How to judge if the actual start date is empty?

guozhencheng · March 31, 2017, 2:38am

Hi,

I can get the value of actual start date by “task.get(Tsk.ACTUAL_START)”, I’d like to know how to judge if the actual start date is empty when the value is ‘N/A’ in MSP.

Best Regards!

Hi Zhencheng,

Thank you for contacting Aspose support team again.

Aspose.Tasks sets minimum date value in the date fields which are not set in the project. You may try following sample code which identifies empty ActualStart field in the attached sample project file. Task 1 contains NA value where as Task 2 contains proper date.

Project proj = new Project("ActualStartNA.xml");

java.util.Calendar tempDate = java.util.Calendar.getInstance();

tempDate.set(1, 0, 1, 0, 0, 0);

Date MinDate = tempDate.getTime();

Task task1 = proj.getRootTask().getChildren().getByUid(1);

Date dt1 = task1.get(Tsk.ACTUAL_START);

if(dt1.toString().compareTo(MinDate.toString())
== 0)

System.out.println(“NA”);

else

System.out.println(dt1.toString());

Task task2 = proj.getRootTask().getChildren().getByUid(2);

Date dt2 = task2.get(Tsk.ACTUAL_START);

if(dt2.toString().compareTo(MinDate.toString())
== 0)

System.out.println(“NA”);

else

System.out.println(dt2.toString());

Hi ,

In case the actual start date in the MSP is just ‘1/1/01 00:00:00’, it is not empty at this point, how can I do?

One more thing, I observed the empty is not always parsed to ‘1/1/01 00:00:00’, sometimes the empty will be parsed to ‘1/1/01 01:00:00’, how to do in this case?

Best Regards!

Hi Zhencheng,

Thank you for writing us back.

Please forward us a sample input file which shows date like '1/1/01 01:00:00' and not always parsing to '1/1/01 00:00:00'. This will help us to reproduce the issue at our end.
