Hi,
I have written one program in which I am processing one shape file.
Once I process it I want to delete the shape file from physical
memory. for that I have written a below example program.
PRO ex_shapefile
file = dialog_pickfile()
; Open the states Shapefile in the examples directory.
myshape=OBJ_NEW('IDLffShape', file)
; Get the number of entities so we can parse through them.
myshape->GetProperty, N_ENTITIES=num_ent
; Read all the entities.
FOR x=1, (num_ent-1) DO BEGIN
;Read the entity x
ent = myshape->GetEntity(x)
;Clean-up of pointers
myshape->DestroyEntity, ent
ENDFOR
; Though next statement is not required because I have open my shape
file in read only mode
myshape->Close
; Close the Shapefile.
OBJ_DESTROY, myshape
; My Process
;Delete shape file Problem is over here.
; though I have close the file I have destroy the object then also not
able to delete the file
file_delete,file
END
Now my problem is whenever I am deleting the file through file_delete
procedure , IDL is giving me error permission denied. I am having all
the rights for a folder in which this file is available.
That means IDL is not allowing me to delete the above file .... :-
( ... Is it a bug in IDL? Kindly correct me if I am wrong.
Regards
Chintan
