Managing Resource Extended Attributes

The ExtendedAttribute property exposed by the Resource class can be used to manage the extended attributes of a resource. This property reads and writes an ArrayList of the ExtendedAttribute objects to deal with a resource’s extended attributes. The ExtendedAttribute object further exposes the relevant properties.

Setting Extended Resource Attributes with Aspose.Tasks

The following code example demonstrates how to set a resource’s extended attributes.

// Create project instance
System::SharedPtr<Project> project1 = System::MakeObject<Project>(dataDir + u"ResourceExtendedAttributes.mpp");
        
// Define extended attribute
System::SharedPtr<ExtendedAttributeDefinition> myNumber1 = project1->get_ExtendedAttributes()->GetById((int32_t)Aspose::Tasks::ExtendedAttributeTask::Number1);
if (myNumber1 == nullptr)
{
    myNumber1 = ExtendedAttributeDefinition::CreateResourceDefinition(Aspose::Tasks::ExtendedAttributeResource::Number1, u"Age");
    project1->get_ExtendedAttributes()->Add(myNumber1);
}
        
// Create extended attribute and set its value
System::SharedPtr<ExtendedAttribute> number1Resource = myNumber1->CreateExtendedAttribute();
number1Resource->set_NumericValue(System::Decimal("30.5345"));
        
// Add a new resource and its extended attribute   
System::SharedPtr<Resource> rsc = project1->get_Resources()->Add(u"R1");
rsc->get_ExtendedAttributes()->Add(number1Resource);
        
// Save project as MPP
project1->Save(dataDir + u"ResourceExtendedAttributes_out.mpp", Aspose::Tasks::Saving::SaveFileFormat::MPP);
