TE_E_TEOBJECT_NOLONGEREXIST |
The object you are trying to access no longer exists. This may have occurred because, while keeping an interface to the object, the user deleted it from TerraExplorer (via the TE user interface). Without the object, the interface cannot be used. Therefore, you should release the interface. |
|
TE_E_INTERNAL |
TerraExplorer was unable to create the object. To get more information about this error use the IErrorInfo Interface. |
