Difference: Select/Case/EndSelect<->If/ElseIf/EndIf

Recommended Posts

I know its maybe a total noob question.

I have written several scripts,one nearly 2000 lines long and pretty complicated, but I'm still trying to figure it out since my autoit starting days.

I cannot see any difference beetwen the two things,....and I am pretty sure there must be one.

(Or otherwise it would be senseless)

hoping for some enlightenment :D

If there are a lot of tests to make then Select gives a slightly simpler code ("Case:" replaces "If then elseif") and is easier to read IMO, but otherwise it is only a matter of using whichever you prefer. I don't think there is any difference between the ways methods otherwise, but maybe one has a minor speed advantage.


Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

Select .. Case .. EndSelect allows you to use ContinueCase which has no equivalent with the If .. ElseIf .. Else .. Endif construct.

Good point.

I guess it deserves a bit of attention at times, as I seldom see it employed. There are only 2 occurences in the standard include UDFs (in FF.au3).

It can really save the day by cutting some weird corners in an otherwise straightforward logic.
