Task GUID (task field)
Data Type Text
Entry Type Calculated
Description The Task GUID field contains the generated unique identification codes for each task 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.
