Detect whether an object is open
It's often necessary to know whether a particular database object is open before you can edit the object programmatically. The following example illustrates how to use the SysCmd method with the acSysCmdGetObjectState action to determine whether a database object is open.
The example function, IsObjectLoaded, accepts two parameters. The strObjectName parameter is the name of the database object to check for. The strObjectType parameter is an AcObjectType constant that specifies the type of database object to check for. The IsObjectLoaded function returns True if the specified database object is open, and returns False if it is not open.
Function IsObjectLoaded(ByVal strObjectName As String, ByVal strObjectType As AcObjectType) As Boolean
If SysCmd(acSysCmdGetObjectState, strObjectType, strObjectName) <> 0 Then
' The object is open.
IsObjectLoaded = True
Else
' The object is not open.
IsObjectLoaded = False
End If
End Function
