PacMe!

Added better example :lmao:

If the files that you pack are big (perhaps above 300kb) be perpared to spend your afternoon.... waiting lol.

Here is a little program I wrote so that you can protect files that your program uses, such as: Images, Music Files, Text Files, and more. It packs together as one file, and all you need to do is call, _pacExtractFile("main_package_name.pac", "original_filename.ext", "outputname.ext") and it extracts the file to the specified location.

Using the Pacme program is pretty self explanatory but i'll explain...

All you need to do, is click, "Add File", and then choose the file you want to be in your package. And if you no longer want that file, all you need to do is click, Remove File.

After you have gotten all the files you want in the package, Click, Make Package, and it will let you name your package, and save it to the specified file. From there you can do whatever you'd like with the file. :ph34r:

Pacme.au3 - Main File.

#include <GUIConstants.au3>
#include <GUIlist.au3>

I was thinking about doing something like this but never got round to it. This is really good.

I noticed that you do not check to see if $sInFileName exists in the package. This can be done by adding one line to _pacExtractFile:

Func _pacExtractFile($sPacFile, $sInFileName, $sOutFileName)
    $sCompareFileName = "~~~~~~~~~~~~~~~~~~~~~~~$#BEGIN_FILE=" & _pacHeaderEncode($sInFileName)
    $sCompareEndFileName = "~~~~~~~#END_FILE=" & _pacHeaderEncode($sInFileName)
    Local $nStartLine = 0
    Local $nEndLine   = 0
    Local $avLines
    _FileReadToArray($sPacFile, $avLines)
    if not (IsArray($avLines)) Then return -1
    Do
        $nStartLine += 1
        If $nStartLine = UBound($avLines) Then Return -1 ;file does not exist
    Until ($avLines[$nStartLine] == $sCompareFileName)
    Do
        $nEndLine += 1
    Until ($avLines[$nEndLine] == $sCompareEndFileName)
    Local $sData = $nStartLine+1
    $out = FileOpen($sOutFileName, 1)
    FIleWrite($out, _HexToString($avLines[$sData]))
    FileClose($out)
    if (@error) then return -1
    return $sOutFileName
EndFunc

This is similar in nature to my AgentEncrypt which people didn't take on to all that well. I used FileInstall with AutoIt as my method and an inputbox with encrypted pasword.

That's not what this does. lol (well yeah. The general concept i guess)

This makes a package of all the files you included. Similiar to that of a zip file, except it does not compress the data. Then you can use the function: _pacExtractFile($pacfile, $inFile, $outFile) to extract the specified file. And just treat the file that was extracted normally..

like:

$temp_name = _TempName()
$file = _pacExtractFile("DataRunner.pac", "clown.bmp", @TempDir&"\"&$temp_name)
GUICtrlCreatePic($file, 32, 32)

Just something like that

:lmao:

No offense, but isn't that EXACTLY what the built in windows tool "iexpress" does? Search you computer for a file called "iexpress.exe". It should be in the System32 folder. Let me know if I'm wrong...

somewhat... Iexpress actually builds somewhat of an installer. This is used for extracting data from within YOUR program. You can use the function _pacExtractFile() to get the file from in your program, then delete it when done using it.

If you try out the game called in the examples, it will explain it better than I can...

Your adding 1 to each byte? Bytes only go up to 255.

Asc(Chr(256)); Returns 0
Just need something to change bytes that are 255 to 0 in _pacHeaderEncode() and the inverse in _pacHeaderDecode(). Unless, of course, I've missed something. Other than that, this is very cool.

Thanks. Fixed that :lmao:

Well, then you have things going to 255(from 254), and things staying at 255... I ment something like:

Func _pacHeaderEncode($sData)
    Local $str = StringSplit($sData, "")
    Local $retString = ""
    For $i = 1 to $str[0]
        if (Asc($str[$i]) == 255) Then
            $retString &= Chr(Asc(0))
        Else
            $retString &= Chr(Asc($str[$i])+1)
        EndIf
    Next
    Return $retString
EndFunc

Func _pacHeaderDecode($sData)
    Local $str = StringSplit($sData, "")
    Local $retString = ""
    For $i = 1 to $str[0]
        if (Asc($str[$i]) == 0) Then
            $retString &= Chr(Asc(255))
        Else
            $retString &= Chr(Asc($str[$i])-1)
        EndIf
    Next
    Return $retString
EndFunc

Actually, Isn't Chr(Asc(255)) the same as Chr(255)? The way I see, the second way is faster because it only calls one function.

Lol, I didn't notice that either... Chr(Asc(255)).. Asc(string) must have gotten the ascii value for 2(first character of the number converted to a string). Then Chr(number) would alwas return with 2... Oops.

Wow, this is one of the best scripts i've ever seen! Great idea! It's very useful to me. I've come up with a few features there could and should be added. (You should consider continuing with this script, it's great!)

-Progress bar

-Faster compilation

I have a 400kb dll I want compiled, yet it's taking forever, and i'm impatient, but still it's great.

Keep up the good work!
