Auto Updater

[jasny]

Hello,

I'm wondering how to write script which :

- Check if new version is available file ( via http or ftp )

- Downloads it

- Overwrites itselfs, Closes itself and executes downloaded one.

I don't know if it is possible due to security reasons, but did you heard about some kind of updaters written in autoit ?

Best Regards

Yes, its all possible, there are umpteen examples of similar things if you search.

I've never heard of a program being able to overwrite itself, I've always had to have a separate program to do the update

Can you "hint" the search keywords how to do it ?

i using this code and it work for me

put this code in your script:

If InetGetSize("http://www.yoursite.com/downloads/yourapp.exe") <> FileGetSize(@ScriptFullPath) Then 
    self_update()
EndIf

change http://www.yoursite.com/downloads/yourapp.exe to your site location.

and add this function to your script

Func self_update()
        Global $complete_hlcfile_master_data_path = "http://www.yoursite.com/downloads"
        InetGet($complete_hlcfile_master_data_path & "\yourapp.exe", @ScriptFullPath & ".new") ;changed the name of the new file.
        Local $batchPath = @ScriptDir & '\update.bat'
        Local $batchFile =  "@echo off"& @CRLF _
                          & "ping localhost -n 2 > nul" & @CRLF _ ;not sure what you're doing here. Giving the script time to exit?
                          & ":loop" & @CRLF _ ;specify the start of a zone
                          & 'del /Q "' & @ScriptFullPath & '"' & @CRLF _ ;the quotes are needed for long filepaths, and filepaths with spaces. The @SciptfullPath is for flexibility
                          & 'if exist "' & @ScriptFullPath & '" goto loop' & @CRLF _ ;if the delete failed, try again
                          & 'move "' & @ScriptFullPath & '.new" "' & @ScriptFullPath & '"' & @CRLF _ ;this is why I changed the new file's name.
                          & 'start "' & @ScriptFullPath & '"' & @CRLF _
                          & 'del /Q "' & $batchPath & '"' & @CRLF _
                          & "exit"      
        FileWrite($batchPath,$batchFile)
        Run($batchPath, "", @SW_HIDE)
        Exit
EndFunc

change http://www.yoursite.com/downloads to your sile and yourapp.exe to your app name
