Hey Guyz,
Came to know about this cute little secret of Dictionary and thought
of sharing with everyone ( It could be the case that you will be
knowing it before hand, so in that case please bear with me )
Problem Statement :
Wanted to check whether I've already created a dictionary object with
the same name and if yes then delete the previous one to create a new
one.
Hindrance Encountered :
We have .exists method for a dictionary object to check for a key
inside we doesn't provide any method per-se specifically to check for
a object to be already a dictionary object. We can check for a name to
be objcet using IsObject ( objName )
Amusing Thing :
What i encountered is on creating a dictionary with a same name with
which a dictionary is already present actually doesn;t throw any error
and hence allows the developer to run ( yes, this make the initial
data to get lost which is actually a cause for concern, hence be
careful ).
Eg:-
Set AFDict = CreateObject("Scripting.dictionary")
AFDict .Add "1", "wew wew"
AFDict .Add "2", "wew wew"
If IsObject(AFDict ) then
msgbox "Yes"
End if
msgbox AFDict.Count
Set AFDict = CreateObject("Scripting.dictionary")
msgbox AFDict.Count
First msgbox will show '2' but second msgbox will show '0'.
Cheers ...
