Exclusive file locking
I've run into the problem where multiple script processes writing to a log file at the same time can interfere with one another. That is, file writes using FileWriteLine are not atomic, so a line of text from one process can have fragments of text from other processes mixed in with it. Exclusive file-locking should take care of the problem.
Looking through the standard UDFs, I see that _WinAPI_LockFile is available, but according to the MSDN documentation it doesn't block - it returns immediately if the lock can't be obtained - and there doesn't seem to be a UDF for the LockFileEx function. I considered writing my own UDF for LockFileEx, but some aspects (e.g., creating the OVERLAPPED structure and its members) look too complex for the amount of time I have available. I think approximating LockFileEx using LockFile could solve my problem, but I'd like to keep it simple while still working reliably. I'm not confident that (e.g.) a simple retry loop to simulate blocking will be adequate.
Any suggestions for a simple way to achieve exclusive file-locking with blocking?
IRC UDF - Updated Version of Chips' IRC UDF - Release: V1.22 - 09/06/2016 - Technical Writer Needed!
A UDF to connect to IRC using TCP Functions, as well as perform actions once connected.
WANTED: Technical Writer able to create / maintain a helpfile (.chm) using the Autoit helpfile layout for an negotiated rate.
Originally created by Chip.
UDF Headers updated compared to old script.
Error and Parameter Handling updated compared to old script.
If you need to bypass the RFC compliance of this UDF, use _IRCRaw.
The majority of the old functions have been modified. It will break most, if not all, scripts using the old UDF.
These commands should work on every server following either RFC 1459 (legacy) or RFC 2812 (preferred).
IRC Chat Clients
Chatroom Integration for software
IRC Bots for Channel / Server Administration
IRC Bots for Games such as Hangman, Mafia, and WereWolf
Remote Administration without having to setup your own AutoIt server
Chips' Old UDF Topic:
While these downloads are more stable than the ones above, I do not have time to thoroughly test all functions and variable entries. If something doesn't work as expected or gives you an error please check @error and @extended variables then create a reply to this topic.

Message output only displays ANSI characters in CUI. (Can't Fix) Freenode requires registration for part messages thus the part message in example doesn't show up (Can't fix) Messages (e.g. PRIVMSG) are not forwarded?, when it contains umlauts/german mutations and when the message only contains a dot '.' (Unconfirmed) Warnings:
Do NOT send a lot of messages at once. MOST networks will disconnect you. SOME networks will permanently ban you. A MINORITY will harshly retailiate. Do NOT use the Sleep() function in your scripts. It prevents you from receiving any new data, can disconnect your from the network, and have other undesired consequences. Use the TimerInit() and TimerDiff() functions and possibly a message queue. To Do:
Possibly add in SSL functionality Create More Functions for IRC commands An entire IRC daemon written in AutoIt Have _IRCChannelJoin check the channel list for errors Have _IRCChannelPart check the channel list for errors Possibly Include Kips TCP UDF for ASync Port Listening in Example Create Additional UDFs for extras such as CTCP, DCC, and Error Lookup Experiment with having functions check for the reply and see if reliable. Have _IRCMultiMode Check if User or Channel and Accept or Deny $_sParams Accordingly Upcoming Changes:
To Be Decided
OOo/LibO Calc UDF
I decided to enhance the functionality of the OOo COM UDF found >here and >here. Thanks to Leagnus and Andy G for providing the initial functions and framework. I've managed to put many features here, but unfortunately, the feature I am unable to get to work is the sort feature.
This UDF includes the following working functions:
Functions to be fixed/implemented:
Please help me test this and let me know of any problems, questions, suggestions or comments you may have. I have tested this with LibreOffice, but not with OpenOffice.
Edit (August 5, 2016): Latest files have been uploaded. Script-breaking changes include renaming the functions to start with _OOoCalc_.
Event-based scripting with the windows shell COM object
I want to listen for certain windows events like window open/closed. After reading the help I think I need to use ObjCreate('shell.application') and ObjEvent with that object to create/register a listener. The problem is I don't know what interface or events (i.e. the specific event names) are available for the listener. I tried searching MSDN but it is a labyrinth and I'm not that familiar with the programming frameworks/models used by Windows, and all the examples seem to refer to compiled code using .NET or some other api.
Can any1 point me in the right direction? Also is using COM objects considered the 'modern' way to do this, or should I be using some other framework/resources?
To skip code if it is a library
Is there any way to skip the execution of a particular block of code like any condition or expression, if the au3 file is included as library.?
Like, in my code I wrote all the functionality as functions and called them in 4 lines.
Now I have another requirement where I need to use the same code but different.So I am importing this code so that I can use these functions.
But the code block which is outside the functions (main code) is being executed when I import the au3 file.Is there any condition to check whether the file is running directly or included in another au3 file as library, so that I can keep the same here.
Please suggest if any ideas.
