The ENVI::HideExtensionFiles method prevents specific .pro and .sav files from appearing in the Toolbox.

Note: This method will not remove Toolbox extensions that were explicitly added with the ENVI::AddExtension method.


Suppose that you create extensions named,, and Omega.sav and move them to your local ENVI_install_dir/extensions directory. The following code shows how to hide from the Toolbox:

; Launch the application
e = ENVI()
; Hide Omega.sav from the Toolbox
e.HideExtensionFiles, ''


ENVI.HideExtensionFiles, Name



A string or string array denoting the name(s) of the files to exclude from the Toolbox. Name can consist of .pro files, .sav files, or any mixture of the two types. ENVI searches for these files in the extension deployment directories (see Write and Deploy Extensions for a list of these directories).


Keywords are applied only during the initial creation of the object.


Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See Manage Errors for more information on error handling in ENVI programming.
