Description
Returns the value of an item type attribute in a process. Use the correct function for your attribute type. All attribute types except number, date, and event use GetItemAttrText.
For GetItemAttrText(), GetItemAttrNumber(), and GetItemAttrDate(), you can specify TRUE for the ignore_notfound parameter to ignore the exception encountered if the specified item type attribute does not exist. In this case the function returns a null value but does not raise an exception. For example, you can use this parameter if a new item type attribute is added to an item type, and your code needs to handle both the earlier version and the upgraded version of the item type.
Arguments (input)
| itemtype | A valid item type. |
| itemkey | A string generated from the application object's primary key. The string uniquely identifies the item within an item type. The item type and key together identify the process. See: CreateProcess. |
Note: Pass #SYNCH as the itemkey to create a forced synchronous process. See: Synchronous, Asynchronous, and Forced Synchronous Processes.
| aname | The internal name of an item type attribute, for GetItemAttrText(), GetItemAttrNumber(), and GetItemAttrDate(). |
| name | The internal name of an item type attribute, for GetItemAttrEvent(). |
| ignore_notfound | Specify TRUE or FALSE to indicate whether to ignore the exception if the specified item type attribute does not exist, for GetItemAttrText(), GetItemAttrNumber(), and GetItemAttrDate(). If you specify TRUE and the item type attribute you specify does not exist, the function returns a null value but does not raise an exception. Defaults to FALSE. |
