Working Code Just looking at cleanup

4 posts in this topic

I have a working script so I am not looking for that type of help, but I am looking at being a better coder so would love for people to take a look at my code and tell me where i went the long way around and what would be better coding practices. The program main fuction is to back up a directory.

The flow is as follows:

Start timer

map network drive based on credentials given

locate all files in base dir given in .ini file

zip files

copy zip to network drive

del network drive

at the same time give a gui log and backend running log of the process

I will also be working on a script that will read these zip files and extract only certain files back out based on user needs so any thing that I may want to do to the backup process now to help later would be great.

Thanks in advance for any suggestions :)

you will need the 7zip udf from Rasim Got it here.

settings.ini file looks like this

[General]

Loc=C:\Documents and Settings\user\Desktop\Lab Backup

Dest=\\usandl0000\app lab backup

Filetype=.zip

Not tested, overall looks good

replace this...

Func Report($_desc,$_ctrl_1="")

GUICtrlSetData($_ctrl_1, $_desc & @CRLF, 1)

EndFunc

you are not using all of those other controls

You need error checking, you're using arrays, but not validating that they are in fact an array or if an error occurred. The way it is written is if you are in a 100% optimal environment, which will only happen (on your PC) lol.

Just a quick example:

Func _iniread($ini)
    Local $aArray[1][3]
    $sect_Ini = IniReadSectionNames($ini)
    For $a = 1 to $sect_Ini[0]
        $set_Ini = IniReadSection($Ini,$sect_Ini[$a]); Read in Section
        for $b =1 to $set_Ini[0][0]
            redim $aArray[ubound($aArray)+1][3]
            $aArray[UBound($aArray)-1][0] = $sect_ini[$a]
            $aArray[UBound($aArray)-1][1] = $set_Ini[$b][0]
            $aArray[UBound($aArray)-1][2] = $set_Ini[$b][1]
        Next
    Next
    return $aArray
EndFunc

Might become:

$a_returned = _IniRead("C:\AU3\ChangeLog.ini")
If Not @error Then
    _ArrayDisplay($a_returned, "Ini's Values")
EndIf

Func _IniRead($s_ini)
    Local $a_array[1][3], $a_section, $i_count
    Local $a_names = IniReadSectionNames($s_ini)
; Now we have to verify where ever called this if there was an error so we don't crash that part
    If @error Then Return SetError(1, 0, 0)
    
    For $i = 1 To $a_names[0]
        $a_section = IniReadSection($s_ini, $a_names[$i])
    ; No need to throw an error (called with non-array variable)
        If @error Then ContinueLoop
    ; We only need to Redim once, Redim takes a lot of time in a loop
    ; We should try and find the fastest most efficient method
        ReDim $a_array[$a_array[0][0] + $a_section[0][0] + 1][3]
        For $n = 1 To $a_section[0][0]
            $i_count += 1; Used to keep track of where we are in the element increment
            $a_array[$i_count][0] = $a_names[$i]
            $a_array[$i_count][1] = $a_section[$n][0]
            $a_array[$i_count][2] = $a_section[$n][1]
        Next
    ; [0][0] will have the total number of elements now
        $a_array[0][0] += $a_section[0][0]
    Next
    
    Return $a_array
EndFunc
May look like more code, but you'll see I know if something fails, and the way I incremented the array ubound will be much faster.
