Task GUID (task field)

Data Type    Text (text field: A type of field whose content is text. Examples include the Task Name and Email Address fields. This field can contain up to 255 characters.)

Entry Type    Calculated (calculated field: A field in which the value is determined by Project based on information in other fields. Project may recalculate the value automatically or when you specify, depending on your choice of calculation settings.)

Description    The Task GUID field contains the generated unique identification codes for each task (task: An activity that has a beginning and an end. Project plans are made up of tasks.) in your project. No two tasks will have the same Task GUID.

How Calculated    As soon as you create a new task, Microsoft Office Project 2007 automatically generates a unique identifier and enters it in the Task GUID field.

Best Uses    Insert the Task GUID column into a task sheet when you need to see the unique identifier for each task. This is particularly useful to help with programming and debugging custom applications in Office Project 2007.

Example    You are creating a macro that references specific tasks in your project. To show the unique identifiers for these particular tasks, you insert the Task GUID column into the Task Sheet.

Remarks    The Task GUID is different from the Unique ID field for tasks. The Unique ID is a sequential number that reflects the order in which tasks were added to the project. By contrast, the Task GUID is a unique alphanumeric string that represents each task for programming purposes.
