If you set within a window, a given color as transparent, every area of that window painted with that color, act as an hole through wich you can see what's behind, and click on what's behind as well.
Here, for example, is a simple effect of fishes swimming around on the screen.
#include <WinAPI.au3> #include <WindowsConstants.au3> #include <Misc.au3> ; for _IsPressed (23 END key) Local $hDLL = DllOpen("user32.dll"), $oIE = ObjCreate("Shell.Explorer.2") Local $hBackground = GUICreate("", @DesktopWidth, @DesktopHeight, 0, 0, $WS_POPUPWINDOW, $WS_EX_LAYERED + $WS_EX_TOPMOST) Local $AlphaKey = 0xF0F7FF ; everything with color $AlphaKey within this window will be transparent ; even if within an embedded browser control!..... _WinAPI_SetLayeredWindowAttributes($hBackground, $AlphaKey, 0, $LWA_COLORKEY) GUISetState(@SW_SHOW, $hBackground) $hIE = GUICtrlCreateObj($oIE, 0, 0, @DesktopWidth, @DesktopHeight) ; <- embedd $oIE in the AutoIt GUI GUISetBkColor($AlphaKey, $hBackground) ; $AlphaKey $hBackground transparent $oIE.navigate('http://cdn.abowman.com/widgets/fish/fish.swf') ; $oIE.navigate('http://cdn.abowman.com/widgets/spider/spider.swf') ; a spider goes around on the screen .... ; !! to use the spider.swf, you need to set $AlphaKey = 0xffffff on line 7 "! While True If _IsPressed("23", $hDLL) Then ExitLoop ; END key was pressed Sleep(250) WEnd $oIE = "" $hDLL = "" GUIDelete($hBackground)
Here, too, the aim is to show an interesting effect that can be obtained by exploiting transparency, but can also be used as it is just for fun.
The animation consists of some fish wandering around the screen. You can continue working on the computer by letting them swim.
I hope you find it relaxing.
AutoIt-Events is an event Observer and is a core dependency for Autoit-Socket-IO but can be used for any Autoit project.
#include "Event.au3" ; Subscribe listeners _Event_Listen(UserCreatedEvent, SendWelcomeMail) _Event_Listen(UserCreatedEvent, RegisterNewsLetter) ; Fire event _Event(UserCreatedEvent, @UserName, "firstname.lastname@example.org") Func UserCreatedEvent(Const ByRef $oEvent, $name, $email) ; via $oEvent you can pass data to its listeners $oEvent.add("name", $name) $oEvent.add("email", $email) $oEvent.add("id", 1) EndFunc Func SendWelcomeMail(Const $oEvent) MsgBox(64, "Welcome mail sent", "Welcome mail sent to " & $oEvent.item("name") & " with email " & $oEvent.item("email")) EndFunc Func RegisterNewsLetter(Const $oEvent) MsgBox(64, "News letter registred", "News letter bound to user id " & $oEvent.item("id")) EndFunc
The code is also available at Github
Version 2.x.x and 3.x.x has been moved to branch 3.x
Autoit-Socket-IO is a event driven TCP/IP wrapper heavily inspired from Socket.IO with focus on user friendliness and long term sustainability.
I constantly want to make this UDF faster and better, so if you have any suggestions or questions (beginner and advanced) Do not hesitate to ask them, I will gladly help!
Simple API 99% data-type serialization thanks to Autoit-Serialize Can easily be extended with your own functionality thanks to Autoit-Events "Educational" examples Data encryption thanks to _<Crypt.au3> Limitations
Speed. This UDF will sacrifice some speed for convenience Getting started
Download the script from AutoIt or pull it from the official github repo email@example.com:tarreislam/Autoit-Socket-IO.git and checkout the tag 4.0.0-beta Check out the documentaion Take a look in the examples/ folder Changelog
To see changes from 3.x.x and 2.x.x please checkout the 3.x branch
Version 4.0.0-beta (This update break scripts.)
Code base fully rewritten with Autoit-Events and decoupled to improve code quality and reduce bloat. The new UDF is very different from 3.x.x so please checkout the UPGRADE guide to fully understand all changes Added new documentation documentaion Success stories
Since December 2017-now I have used version 1.5.0 in an production environment for 150+ clients with great success, the only downtime is planned windows updates and power outages.
Newest version (2020-09-15!)
