Work with Task Views

Aspose.Tasks for C++ API supports rendering project tasks to a variety of formats, such as PDF. Task usage can be rendered using Aspose.Tasks’ PresentationFormat with different timescale settings like Days, ThirdOfMonths and Months.

Rendering Task Usage View

The code snippet in this article reads a source MPP file that has a number of tasks with assigned resources and renders these to output PDF using the following steps:

1. Create an instance of the Project class.
2. Read the source MPP file.
3. Initiate the SaveOptions object with required timescale settings.
4. Set the presentation format to TaskUsage.
5. Render the project to PDF output.

// Create project instance
System::String dataDir = RunExamples::GetDataDir(System::Reflection::MethodBase::GetCurrentMethod(ASPOSE_CURRENT_FUNCTION)->get_DeclaringType().get_FullName());
System::SharedPtr<Project> project1 = System::MakeObject<Project>(dataDir + u"TaskUsageView.mpp");
    
// Define the SaveOptions with required TimeScale settings as Days
System::SharedPtr<SaveOptions> options = System::MakeObject<PdfSaveOptions>();
options->set_Timescale(Aspose::Tasks::Visualization::Timescale::Days);
    
// Set the Presentation format to ResourceUsage
options->set_PresentationFormat(Aspose::Tasks::Visualization::PresentationFormat::TaskUsage);
    
// Save the Project
System::String outputProject = u"project_TaskUsageView_result_days_out.pdf";
project1->Save(dataDir + outputProject, options);
    
// Set the Tiemscale settings to ThirdsOfMonths
options->set_Timescale(Aspose::Tasks::Visualization::Timescale::ThirdsOfMonths);
    
// Save the Project
outputProject = u"project_TaskUsageView_result_thirdsOfMonths_out.pdf";
project1->Save(dataDir + outputProject, options);
    
// Set the Timescale settings to Months
options->set_Timescale(Aspose::Tasks::Visualization::Timescale::Months);
    
// Save the project
outputProject = u"project_TaskUsageView_result_months_out.pdf";
project1->Save(dataDir + outputProject, options);

Rendering Details Column to Output in Task Usage View

Details column included in the MPP file can be rendered to the output using the View’s DisplayDetailsHeaderColumn property. This includes the list of following supported fields:

• Work
• Actual Work
• Actual Overwork time
• Baseline Work
• Baseline 1-10 Work

The following code example illustrates the usage of this property.

// Create project instance
System::String dataDir = RunExamples::GetDataDir(System::Reflection::MethodBase::GetCurrentMethod(ASPOSE_CURRENT_FUNCTION)->get_DeclaringType().get_FullName());
System::SharedPtr<Project> project1 = System::MakeObject<Project>(dataDir + u"TaskUsageViewWithDetails.mpp");
    
// Get Default view
System::SharedPtr<UsageView> view = System::DynamicCast_noexcept<Aspose::Tasks::TaskUsageView>(project1->get_DefaultView());
    
// Details header column will not be displayed
view->set_DisplayDetailsHeaderColumn(false);
view->set_RepeatDetailsHeaderOnAllRows(false);
view->set_AlignDetailsData(System::Drawing::StringAlignment::Near);
project1->Save(dataDir + u"task usage1_out.pdf", Aspose::Tasks::Saving::SaveFileFormat::PDF);
    
// Display details header column
view->set_DisplayDetailsHeaderColumn(true);
    
// Repeat details header on all assignments rows
view->set_RepeatDetailsHeaderOnAllRows(true);
view->set_AlignDetailsData(System::Drawing::StringAlignment::Far);
project1->Save(dataDir + u"task usage2_out.pdf", Aspose::Tasks::Saving::SaveFileFormat::PDF);

Rendering Task Sheet View

The code snippet in this article reads a source MPP file that has a number of tasks with assigned resources and renders these to output PDF using the following steps:

1. Create an instance of the Project class.
2. Read the source MPP file.
3. Initiate the SaveOptions object with required timescale settings.
4. Set the presentation format to TaskSheet.
5. Render the project to PDF output.

// Create project instance
System::String dataDir = RunExamples::GetDataDir(System::Reflection::MethodBase::GetCurrentMethod(ASPOSE_CURRENT_FUNCTION)->get_DeclaringType().get_FullName());
System::SharedPtr<Project> project1 = System::MakeObject<Project>(dataDir + u"TaskSheetView.mpp");
    
// Set presentation format Task Sheet and save project as PDF
System::SharedPtr<SaveOptions> options = System::MakeObject<PdfSaveOptions>();
options->set_PresentationFormat(Aspose::Tasks::Visualization::PresentationFormat::TaskSheet);
project1->Save(dataDir + u"TaskSheetView_out.pdf", options);
