Retrieving file attachments from tasks using the web service API

To retrieve file attachments from tasks by using the web service API, perform the following steps:

1.	Include project files

•	Create a Microsoft .NET client assembly that consumes the TaskManagerQueryService WSDL. (See Creating a .NET client assembly.)

•	Reference the Microsoft .NET client assembly. (See Referencing the .NET client assembly.)

2.	Create a TaskManager Client API object

•	Using the Microsoft .NET client assembly, create a TaskManagerServiceService object by invoking its default constructor.

•	Set the TaskManagerServiceService object’s Credentials data member with a System.Net.NetworkCredential value that specifies the user name and password value.

3.	Retrieve the file attachments

•

Retrieve file attachments by invoking the TaskManagerServiceService object’s getAttachmentListForTask method and passing the task identifier value and a Boolean value that specifies true. This method returns an Object array where each element is a BLOB object that contains a file attachment. You can determine the task identifier by retrieving tasks that are assigned to a specific user. (See Retrieving Tasks Assigned to Users.)

•	Iterate through the Object array by creating a loop structure and, for each element, cast the element value to a BLOB instance.
