Understanding _Singleton and others

9 posts in this topic

I'm still a noob and now I am going to ask some more nooby questions :

1.Kindly explain the _Singleton, the help file isn't enough detailed(for me)

2.How can I make a script which will create a directory at a place(suppose desktop) in it's first run and everytime it is run it'll check if the directory exists and if it doesn't then it'll create the directory again.

3.How to open a folder using autoit?

Hi, SirDarknight.

1. We use _Singleton to check if a script already (still) running.

We might want to use this to prevent our script run more than one instance at a time.

2.

If NOT FileExists(@DesktopDir & "\my_folder\") Then
   DirCreate (@DesktopDir & "\my_folder\")
Endif

 

3. ShellExecute (@DesktopDir & "my_folder")

SirDarknight1200,

- 1. _Singleton effectively creates a flag within Windows each time the exe containing it is run. If you try to run the exe again, Windows notices that the flag is the same and refuses to run it.

- 2. Something along these lines (not tested):

; Define the folder
$sPath = Your+Folder+Path
; See if it exists
If Not FileExists($sPath) Then ; This function works on folders as well
    ; Create it if not
   DirCreate($sPath)
EndIf
; And you have your folder either already existing or newly created
- 3. To choose a folder, use FileSelectFolder[/]i; to display the contents use ShellExecute("Your_Folder_Path").

All clear? :)

Is it even necessary to check for folder existence before creation? If the folder already exists, then the function will fail; just don't test the error return!

Better you post your code and tell what is not running?

SirDarknight1200,

Do you ever read the Help file or search the forum before posting? :huh:

If not then please start doing so in future. ;)

P.S. You need to disable the pic control. ;)
