Search through array and delete elements with wildcard (Resolved)

#1 ·  Posted (edited)

I have a script I've been working on for a while (with the generous help of this forum) that enumerates the applications in Add/Remove Programs on a remote machine. It basically takes the contents of HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and puts them into an array, as shown in the picture. The code I have is below, and it works well:

<BR>#include <Array.au3><BR><BR><BR>AutoItSetOption("WinTitleMatchMode", 2)<BR>$Computer = InputBox("Enumerate Remote Applications", "Please enter the computer you'd like to connect to.")<BR><BR>$addremove = _SoftwareInfo()<BR>_ArraySort($addremove)<BR>_ArrayDisplay($addremove, 'Add/Remove Entries for ' & $Computer & '.')<BR><BR>Func _SoftwareInfo($s_RemoteComputer = $Computer)<BR>    Local $Count = 1<BR>        <BR>    If $s_RemoteComputer <> '' Then $s_RemoteComputer = '\\' & StringReplace($s_RemoteComputer, '\', '') & '\'      <BR>    Local Const $regkey = $s_RemoteComputer & 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall'<BR>    <BR>    While 1<BR>        $key = RegEnumKey ($regkey, $Count)<BR>        If @error <> 0 then ExitLoop<BR>        $line = RegRead ($regkey & '\' & $key, 'Displayname')<BR>        $line = StringReplace ($line, ' (remove only)', '')<BR><BR>        If $line <> '' Then<BR>            If Not IsDeclared('avArray') Then Dim $avArray[1]<BR>            ReDim $avArray[UBound($avArray) + 1]<BR>            $avArray[UBound($avArray) - 1] = $line<BR>        EndIf<BR>        $Count = $Count + 1<BR>WEnd<BR><BR>    If Not IsDeclared('avArray') Or Not IsArray($avArray) Then<BR>        Return(SetError(1, 0, ''))     <BR>    Else<BR>        $avArray[0] = UBound($avArray) - 1<BR>        Return(SetError(0,0, $avArray))<BR>    EndIf<BR>EndFunc<BR>

I have a couple of things I've been trying to do to enhance this, and am hoping someone can steer me in the right direction. Firstly, I have been attempting to search through the array before displaying it, and remove any reference to MS Updates. I've tried a number of ways with _ArraySearch, _ArrayFindAll, and _ArrayDelete, but I keep missing the mark. The code below seems to come closest, but it deletes every element prior to $string, rather than each instance of it. If anyone can shed some light on the correct syntax, I would appreciate it.

<BR>For $element in $addremove<BR>$string = "Security Update for "<BR>If $element >= $string Then<BR>  _ArrayDelete($addremove, $element)<BR>EndIf<BR>Next<BR>

The second item is less important, just more of how to configure the array window. As the screenshot shows, the array comes up in the default size, and you have to resize it to view properly. I searched through the forums and located a thread where someone suggested making a copy of array.au3, renaming it to arraycustom.au3, and then modifying the _ArrayDisplay function to suit your needs. I have done the same, and it seems to be working (mostly). I simply changed the $iWidth variable to "@DesktopWidth / 2" and the $iHeight variable to "@DesktopHeight - 50". This works well for the height, I can get it to display exactly as I need. The width, however, does not change, regardless of what I put in there. Just curious if there is some boundary that is keeping it from resizing.

Again, the second item is so less important than the first. If anyone has thoughts or (constructive) criticism on either, I would appreciate it.

JLogano3013,

"If $element >= $string Then" means that if the array element is greater than or equal to the string value then...

Change to "If $element = $string Then" and see what you get.

Edit: arraydisplay

You might try doing something with $sheader (optional parm for arraydisplay). Possibly: " $sheader = ' ',' ', " etc.

Edit2: Your post title references "wildcard" but I do NOT see any other references to it.

I have updated your original script to include the deletion of the security updates. You should always delete array elements while looping through the array from the end to the start, never the other way around.

I have also included an update to the Zero element of the $addremove array to keep track of how many items are in the list. Plus, when doing the _ArraySort you should start from the first index to avoid sorting the zeroth element by accident, I have a program called µtorrent and that first character causes it to be placed before the uninstall items.

#include <Array.au3>
AutoItSetOption("WinTitleMatchMode", 2)
$Computer = InputBox("Enumerate Remote Applications", "Please enter the computer you'd like to connect to.")
$addremove = _SoftwareInfo()
For $element = UBound($addremove) - 1 To 1 Step -1
    $string = "Security Update for "
    If StringMid($addremove[$element], 1, StringLen($String)) = $string Then
        _ArrayDelete($addremove, $element)
    EndIf
Next
$addremove[0] = UBound($addremove) - 1
_ArraySort($addremove, 0, 1)
_ArrayDisplay($addremove, 'Add/Remove Entries for ' & $Computer & '.')
Func _SoftwareInfo($s_RemoteComputer = $Computer)
    Local $Count = 1
    If $s_RemoteComputer <> '' Then $s_RemoteComputer = '\\' & StringReplace($s_RemoteComputer, '\', '') & '\'
    Local Const $regkey = $s_RemoteComputer & 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall'
    While 1
        $key = RegEnumKey($regkey, $Count)
        If @error <> 0 Then ExitLoop
        $line = RegRead($regkey & '\' & $key, 'Displayname')
;~      $line = StringReplace($line, ' (remove only)', '')
        If $line <> '' Then
            If Not IsDeclared('avArray') Then Dim $avArray[1]
            ReDim $avArray[UBound($avArray) + 1]
            $avArray[UBound($avArray) - 1] = $line
        EndIf
        $Count = $Count + 1
    WEnd
    If Not IsDeclared('avArray') Or Not IsArray($avArray) Then
        Return (SetError(1, 0, ''))
    Else
        $avArray[0] = UBound($avArray) - 1
        Return (SetError(0, 0, $avArray))
    EndIf
EndFunc   ;==>_SoftwareInfo

or just dont add them in the first place

with brewmans code:

edit** I think i see what you were saying about utorrent, as i believe its the same for stripping 7zip, what exactly is causing that?

#include <Array.au3>
AutoItSetOption("WinTitleMatchMode", 2)
$Computer = InputBox("Enumerate Remote Applications", "Please enter the computer you'd like to connect to.")
$addremove = _SoftwareInfo()
_ArraySort ($addremove)
_ArrayDisplay($addremove, 'Add/Remove Entries for ' & $Computer & '.')

Func _SoftwareInfo($s_RemoteComputer = $Computer)
    Local $Count = 1
    If $s_RemoteComputer <> '' Then $s_RemoteComputer = '\\' & StringReplace($s_RemoteComputer, '\', '') & '\'
    Local Const $regkey = $s_RemoteComputer & 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall'
    While 1
        $key = RegEnumKey($regkey, $Count)
        If @error <> 0 Then ExitLoop
        $line = RegRead($regkey & '\' & $key, 'Displayname')
;~      $line = StringReplace($line, ' (remove only)', '')
        If $line <> ''  Then
            If $line = stringinstr($line , "Security Update for") Then
            If Not IsDeclared('avArray') Then Dim $avArray[1]
            ReDim $avArray[UBound($avArray) + 1]
            $avArray[UBound($avArray) - 1] = $line
        EndIf
        Endif
        $Count = $Count + 1
    WEnd
    If Not IsDeclared('avArray') Or Not IsArray($avArray) Then
        Return (SetError(1, 0, ''))
    Else
        $avArray[0] = UBound($avArray) - 1
        Return (SetError(0, 0, $avArray))
    EndIf
EndFunc   ;==>_SoftwareInfo

Another update that avoids adding the entries for Security Updates as iamthekey suggested, but without doing a ReDim every line. This shaved nearly 50% off the run time by avoiding using ReDim and nearly 75% off of the way I was doing it with the ArrayDelete.

The way that the search was being done in the code that iamthekey posted was causing 7Zip to be skipped, luckily I have 7zip installed on this computer so I could see the issue, and I figured out how to avoid that by doing a string to string comparison rather than having it do a number to string comparison which is never a good idea from what I've seen.

So it's kind of a mish-mash between our two tries at this.

#include <Array.au3>
AutoItSetOption("WinTitleMatchMode", 2)
$Timer = TimerInit()
$Computer = InputBox("Enumerate Remote Applications", "Please enter the computer you'd like to connect to.")
$Timer = TimerInit()
$addremove = _SoftwareInfo()
_ArraySort($addremove, 0, 1)
$Diff = TimerDiff($Timer)
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $Diff = ' & $Diff & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console
_ArrayDisplay($addremove, 'Add/Remove Entries for ' & $Computer & '.')
Func _SoftwareInfo($s_RemoteComputer = $Computer)
    Local $Count = 1, $Count1 = 1
    If $s_RemoteComputer <> '' Then $s_RemoteComputer = '\\' & StringReplace($s_RemoteComputer, '\', '') & '\'
    Local Const $regkey = $s_RemoteComputer & 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall'
    While 1
        $key = RegEnumKey($regkey, $Count1)
        If @error <> 0 Then ExitLoop
        $line = RegRead($regkey & '\' & $key, 'Displayname')
;~      $line = StringReplace($line, ' (remove only)', '')
        If $line <> '' Then
            If StringMid($line, 1, 19) <> "Security Update for" Then
;~          If $line = StringInStr($line, "Security Update for") Then
                If Not IsDeclared('avArray') Then Dim $avArray[100]
                If UBound($avArray) - $Count <= 1 Then ReDim $avArray[UBound($avArray) + 100]
                $avArray[$Count] = $line
                $Count = $Count + 1
            EndIf
        EndIf
        $Count1 += 1
    WEnd
    If Not IsDeclared('avArray') Or Not IsArray($avArray) Then
        Return (SetError(1, 0, ''))
    Else
        ReDim $avArray[$Count - 1]
        $avArray[0] = UBound($avArray) - 1
        Return (SetError(0, 0, $avArray))
    EndIf
EndFunc   ;==>_SoftwareInfo

An easy way to delete elements from an array without using ReDim (very slow) is to duplicate the array, loop through the second one and delete from the first. When you are finished you just empty the second array

$aArray2 = $aArray
For $i= 1 To UBound($aArray2) -1
   If <condition> Then _ArrayDelete($aArray, $i) ; There may be a better method to delete it but my mind is asleep
Next
$aArray2 = ""

I seem to recall that _ArrayDelete uses ReDim so using it there is bad enough without using it again

Another way is to convert the array to a string and then use StringReplace(). There are a few ways to skin the kitty with this one.

Many thanks to all of you for the help. The combination of your assistance gave me just what I was looking for, and will make this 100% better for those using the script. Thanks again.

I only used ReDim, in my last example, when I had to add items to the array and then only once every 100 items. The final ReDim was to trim off the excess blank elements that would be left over after the loop had finished. It minimizes the impact of using ReDim in the script, and I didn't have to use _ArrayDelete at all.

@GEOSoft

Wouldn't you want to loop through the array backwards when you're deleting elements from it? Otherwise you end up with an out of bounds error, and you delete the wrong items.
