@argumentumThank you for taking the time to work on this. I know you probably have a million other things you could have spent your time working on, so I really appreciate you releasing an updated version of your script with the fix so quickly.1 point -
I love Libre-Oficce and this UDF will certainly be very useful!1 point

Hi, for quite a bunch of PDF files with mixed and somewhat complex content I've tried several tools out the, that can convert PDF to TEXT. Those that are command line capable like PDFtoTEXT.EXE unfortunately are 1.) slow and 2.) the resulting TXT files are not presenting proper content. Best results I got so far using the Foxit Reader: Fast and reliably creates correct content in the resulting TXT files, but Foxit Reader is not command line capable in a manner to use it for batch processing. So I wrote this script (ugly: Using a lot of send() commands, as ControlClick() to the appropriate control-IDs doesn't seem to work), and I would like to ask here, if someone has either done a better automation for Foxit Reader already, or maybe there is a good alternative approach to convert PDF to TXT files? #include <File.au3> #include <Debug.au3> $foxit="C:\Program Files (x86)\Foxit Software\Foxit Reader\FoxitReader.exe" $DirInputPDF="c:\temp\folder-with-PDF-files" ; put some PDF files here with Text content. Image based PDF cannot be processed that way! $DirOutputTXT="C:\temp\PDF2TXT-result" DirCreate($DirOutputTXT) $aPDF=_FileListToArray($DirInputPDF,"*.pdf",1,0) ; _DebugArrayDisplay($aPDF) for $i = 1 to $aPDF[0] $NxPDF=$aPDF[$i] ShellExecute($foxit,$DirInputPDF & "\" & $NxPDF) WinWait($NxPDF) ToolTip("document " & $NxPDF & " opened") WinActivate($NxPDF) ToolTip("window activated") Sleep(1000) send("{alt}") ToolTip("ALT sent") Sleep(2000) send("f") ; f for open file menu ToolTip("f sent") Sleep(2000) send("a") ; a for save using alternative name ToolTip("a sent") Sleep(2000) ControlClick($NxPDF,"","Button11") ; button to invoke a "search locations" ToolTip("alternative save name dialog button clicked") Sleep(1000) ; the file name input is active $TxtName=$DirOutputTXT & "\" & StringTrimRight($NxPDF,4) ; cut off ".PDF" if FileExists($TxtName & ".TXT") Then FileDelete($TxtName & ".TXT") send($TxtName) Sleep(2000) send("!t") ; Combobox2 cannot be clicked, use ALT+t for file T-ype ToolTip("ALT+t sent to change file type") Sleep(1000) send ("{down}") ; drop down file type combo box ToolTip("{DOWN} send 1st time") Sleep(1000) send ("{down}") ; select "TXT" file type ToolTip("{DOWN} send 2nd time") Sleep(1000) send ("{enter}") ; end file type selection ToolTip("{ENTER} send to end file type selection") Sleep(1000) ; doesnt work ControlClick($NxPDF,"","Button3") ; click SAVE button send("!s") ; hotkey ALT+s for SAVE button Sleep(3000) $CtrlF4Count=0 while WinExists($NxPDF) $CtrlF4Count+=1 WinActivate($NxPDF) send("^{f4}") ; close current document ToolTip("CTRL+F4 sent " & $CtrlF4Count & " times") Sleep(1000) WEnd ToolTip($NxPDF & " done.") Next any suggestions appreciated! <edit> typos </edit>1 point

Well @MattHiggs, there it is ready for download.1 point -
I've had this thing I wrote up laying around for a while now and decided I'd comment the heck out of it and post it here for others to enjoy as well. It's a multi-client TCP server "base" that has all the boilerplate code done, the only thing that one needs to do is just whip their protocol code in to it and it's ready to go. I've included a little few-line example bit in it (in the #region stuff) for a simple echo server. A quick way to see the example work is to just start this up and use a telnet client to connect to it on the port that you chose to have it bind (default in the one I'm posting is port 8080), typing a sentence, and pressing enter. This server makes use of setting the TCPTimeout option to 0, making it quite efficient when a high number of clients are connected and making it faster at accepting new connections. It does not use a fixed-size array for storing client connections, but instead dynamically re-sizes the client array when clients disconnect or connect (Setting $MaxClients to 0 makes the number of simultaneous clients only limited by RAM or AutoIt internal limits, whatever is reached first. I've tested this at 10,000 concurrent connections successfully, albeit with some slightly elevated CPU usage ). The server also implements a simple per-client packet buffer (as shown in the little echo example) which can come in handy for things such as large packets from file transferring and such. Instead of only relying on checking @error after a TCPRecv call to determine if a client disconnected (which can lie in certain cases), this uses a checking function which implements both that @error check and an idle timeout check that disconnects the client if they have not sent anything in a certain period of time. This is not really aimed at people who are unfamiliar with sockets work in AutoIt, as this provides no real application layer protocol, you must make that yourself. The only thing this does is do all the hard and/or tedious work of managing what happens when clients try connecting, how packet data should be buffered, and when a connection should be considered "dead". If you use this in a project, a simple little comment saying you used it would be nice #cs ---------------------------------------------------------------------------- AutoIt Version: 3.3.8.1 (Or greater) Author: Ken Piper Script Function: Template multi-client server base code. Use as a base for making an efficient server program. This base will just accept connections and echo back what it receives, and kill the connection if it is dead or inactive for x seconds. It will not do any other work, that must be added seperately! #ce ---------------------------------------------------------------------------- TCPStartup() Opt("TCPTimeout", 0) #region ;Safe-to-edit things are below Global $BindIP = "0.0.0.0" ;Listen on all addresses Global $BindPort = 8080 ;Listen on port 8080 Global $Timeout = 15000 ;Max idle time is 15 seconds before calling a connection "dead" Global $PacketSize = 2048 ;Max packet size per-check is 2KB Global $MaxClients = 50 ;Max simultaneous clients is 50 #endregion ;Stuff you shouldn't touch is below Global $Listen Global $Clients[1][4] ;[Index][Socket, IP, Timestamp, Buffer] Global $Ws2_32 = DllOpen("Ws2_32.dll") ;Open Ws2_32.dll, it might get used a lot Global $NTDLL = DllOpen("ntdll.dll") ;Open ntdll.dll, it WILL get used a lot Global $CleanupTimer = TimerInit() ;This is used to time when things should be cleaned up OnAutoItExitRegister("Close") ;Register this function to be called if the server needs to exit $Clients[0][0] = 0 $Listen = TCPListen($BindIP, $BindPort, $MaxClients) ;Start listening on the given IP/port If @error Then Exit 1 ;Exit with return code 1 if something was already bound to that IP and port While 1 USleep(5000, $NTDLL) ;This is needed because TCPTimeout is disabled.

Changelog: Cleared up formatting a bit in the [autoit] tags Fixed a bug in how it cleaned up the connection, and fixed a spelling error in the post Fixed a very rare corner-case that could cause a crash when getting many connections and disconnections in a short amount of time Changed a bit of code to fix issues with reading multiple buffered packets Fixed some spelling in the post and clean the code a bit; I try to keep this code up-to-date with the source file on my computer Fixed to add a massive performance increase when handling large numbers of connected clients and the client array needs to be trimmed. (I've seen up to a 500x speed increase on my computer!) Quick fix, apparently I forgot to set the max pending connections in TCPListen, leading for some pretty slow connection-accepting! Sorry about that. Fixed the problem of the latest AutoIt version causing "If @error Then" type statements to fail for TCPRecv, as TCPRecv now sets @error to -1 if the socket is alive but idle. This fixes the problem of clients getting instantly disconnected, sorry about not updating the code here with this sooner.1 point
