Working with Project Files Using Aspose.Tasks

Programmatic Project Management in C#, Java, and Python

An API for interacting with project files in a variety of programming languages is offered by Aspose.Tasks. Regardless of your development platform, Aspose.Tasks provides a uniform experience whether you need to create, edit, analyze, or convert project files. In this section shows how to interact programmatically with project management files, emphasizing task hierarchy parsing and display.
The examples that follow demonstrate how to load a project file, navigate through its task hierarchy, and produce an organized work breakdown structure (WBS) representation. For project analysis, reporting, and visualization, this routine project management duty is crucial.

Get Number of Pages in Project

    Project project = new Project("New Project.mpp");

// Get number of pages,  Timescale.Months, Timescale.ThirdsOfMonths
    int iPages = project.GetPageCount();
    iPages = project.GetPageCount(Timescale.Months);
    iPages = project.GetPageCount(Timescale.ThirdsOfMonths);

The number of pages required to render a Microsoft Project (MPP) file when it is exported to a readable format can be determined using this code sample. First, a Project object is created and an existing MPP file named New Project.mpp is loaded. The total number of pages, based on the default time frame settings, is determined by calling the GetPageCount() function without any parameters. To train the system to determine the number of pages in monthly time frame mode, the function is called again using Timescale.Months. Finally, Timescale.ThirdsOfMonths, which divides each month into three equal sections for greater granularity, is used in the code to obtain the number of pages.

Parsing and Processing Tasks - Making a Task List Tree

// For complete examples and data files, please go to https://github.com/aspose-tasks/Aspose.Tasks-for-Java
// The path to the documents directory.

String dataDir = Utils.getDataDir(ParentAndChildTasks.class);

Project prj = new Project(dataDir + "ParentAndChildTask.mpp");

// Create a ChildTasksCollector instance
ChildTasksCollector collector = new ChildTasksCollector();

// Use TaskUtils to get all children tasks in RootTask
TaskUtils.apply(prj.getRootTask(), collector, 0);

List tasks = collector.getTasks();
int iSize = tasks.size();

// Parse through all the collected tasks
for (int i = 0; i < iSize; i++) {
    Task tsk = (Task) tasks.get(i);
    System.out.println("Task Name = " + tsk.get(Tsk.NAME));
}

This Java code sample shows how to create a hierarchical task list to interpret and process tasks in a Microsoft Project (MPP) file. It loads the MPP file from the specified location to initialize the ‘Project’ object. To collect all the child tasks in the root task of the project, a ‘ChildTasksCollector’ object is subsequently created. The code extracts all the child tasks and stores them in a list using TaskUtils.apply(). After calculating the number of collected tasks, a loop is executed using tsk.get(Tsk.NAME) to get its name. The project task hierarchy is finally displayed on the terminal screen. This method helps to programmatically retrieve important information about the tasks and analyze the project structure.

Update Project and Modify

    using (var archive = new Archive())
    {
        archive.CreateEntry("entry_name1.dat", "input_file1.dat");
        archive.CreateEntry("entry_name2.dat", "input_file2.dat");
        archive.Save("result_archive.whl");
    }

The critical path of a Microsoft Project (MPP) file is ascertained by this C++ code snippet. It loads Project2.mpp into a Project object after first retrieving the directory path containing the project file. Next, by turning off ScheduleFromStart() and designating January 1, 2020, as the project’s completion date, the scheduling mode is changed to Schedule from Finish Date. In order to ensure that dependencies and constraints are appropriately handled, it then recalculates all task dates, including start, finish, early/late start, and early/late finish. Prior to extracting the critical path, the Recalculate() method makes sure that scheduling calculations are updated. The project’s critical route, which includes actions that have an immediate bearing on the project’s completion deadline, is finally retrieved by the code.
