Capture event from external windows

Recommended Posts

Harro,
 
 I am trying to poll Skype for events, I want something to happen when it is minimised.
 
I have found some code on the forum that almost works, I have been tweaking it, but just can't get the minimise event to work. I would love some help on this. as I am not amamzing at DLL calling and such...

the event handle for $EVENT_SYSTEM_MINIMIZEEND is never hit.. even when i minimise the window, i always get the same event codes.

Here is what I have so far...

#include <WindowsConstants.au3>
#include <WinAPI.au3>
#include <Process.au3>
#include <Misc.au3>

Global $hDLL, $hWinEventProc, $hHook

I think you're looking for EVENT_SYSTEM_MINIMIZESTART, not for EVENT_SYSTEM_MINIMIZEEND

Hello,

Even that event is not hit, the only ones i get are

9,8 and 3

Try to change:

Global $EVENT_Min = 0x00000001
Global $EVENT_Max = 0x7FFFFFFF

Does it affects in any way?

 

Brilliant!

though i changed it to

Global $EVENT_Min = $EVENT_SYSTEM_MINIMIZESTART

Global $EVENT_Max = $EVENT_SYSTEM_MINIMIZESTART

your first post was right in the first place, as I did try this before, but with

$EVENT_SYSTEM_MINIMIZEEND

Thank you so much!! ♥

      So first things first the example in the help file for _WinApi_Enum_Windows has an error
      ;_ArrayDisplay($aResult, "_WinAPI_EnumWindows", Default, Default, Default, Default, "#|Handle|Class|Title|Text|Process") Should Be _ArrayDisplay($aResult, "_WinAPI_EnumWindows", Default, Default, Default, "Handle|Class|Title|Text|Process") Next is a bit of helpful info on LPCSTR in a callback function it needs  to be passed as a PTR
      DllCallbackRegister($sFUNCT, $sRETURN, "ptr") Finally on to my question
      I'd want to call EnumPropsEX and pass a string through lparam + append to it rather than declaring anything globally
      I can Come up with two ways to do this The second it a lot more code but possibly safer but the first way I think Should do
      1. From a bit of testing It seems AutoIt won't overflow a DllStruct?
      2. Are strings passed through DLL call guaranteed to be 'an ANSI string (a minimum of 65536 chars is allocated)' as the Helpfile clearly states?

      Hello,
       
      I'm trying to figure out how to add attributes to a Credentials Store.  I have been using it to store Creds and I was using the Comments to store some limited data but I'd really like to start using the 64 possible Attributes so I don't need to use the Registry to store misc information my script needs.
       
      I have been trying to figure this our for a few days now and I'm able to create the structure, but it fails with Invalid Parameter when trying to add the item to the store.
       
      Any ideas or pointers to where to get some further information on this?
      Thanks,
      Mike

      AutoIt-SocketIo
      Yep yep, this is pretty much an attempt to port the existing project's concept https://socket.io/ to AutoIt's Codebase. So i will not go in to so much detail.
      This is how the communication is done http://i.imgur.com/0mMfsBD.png Each client is isolated to the server http://i.imgur.com/rVO2LFb.png Features
      Easy API VarType Translation (Example: If the server sends an int, the client will receive an int and vice versa) Fully featured examples Data encryption (Using Autoit's UDF Crypt.au3) Limitations / Drawbacks
      It is not possible to Broadcast/Emit objects Only 1D-arrays are allowed to be Broadcasted/Emitted (2D arrays will probably never be supported) Changelog
      Version 1.5.0 (This update DOES NOT break scripts)
      Added AutoIt like docs under Docs\. The docs are generated so its a 1 to 1 reflection of the UDF headers. Print of documentation Added a production ready server example. Added a new method: _Io_DevDebug which will display useful information when debugging. Added a new method: _Io_SetMaxRecvPackageSize which defaults to whatever _Io_setRecvPackageSize is set to. Added a new method: _Io_setOnPrefix which defaults to _On_ Added a new default client & server event called flood. Flood occurs when exceeding the $__g_io_nMaxPacketSize. $__g_io_nMaxPacketSize is set by _Io_SetMaxRecvPackageSize Fixed the 16 parameter limit when sending data with _Io_Emit, _Io_Broadcast, _Io_BroadcastToAll and _Io_BroadcastToRoom. This works on the same premise that AutoIt's Call Does Fixed a TRUNCATION problem when receiving packages which could cause crashes! Fixed a programming error which caused $__g_ionPacketSize to reset to default 4096 if _Io_Connect or _Io_listenwere called after _Io_setRecvPackageSize Fixed _Io_setEventPreScript and _Io_setEventPostScript They didnt work. Lol. Changed how events are fired so the client cannot crash the server by sending the wrong number of parameters (This also allows for optional parameters on callbacks) Changed _Io_On. The second parameter $fCallback can now be set to null. Doing this, the function assumes that the callback is: _On_<eventName>.

      I've been working with the Windows Credentials store to store credentials for lots of RDP connections.  I'm also using this code in other scripts to store and retrieve "legacy" credentials for my scripts that have a Save Password checkbox.
      All goes well, until someone requests a button to display a list of all saved credentials.  I found the CredEnumerate call and it looks like it's working but the Target and UserName field that I want is stored inside an array of pointers and I can't figure out how to get data from inside that.  I found a post from 2009 that talks about this, but there was never a solution.
       
      Below are my functions put into an example script.  the _Credentials_Enumerate() is where i'm having problems.   Anybody have some ideas?
      Thanks,
      Mike

      Hello,
      Im trying to read the output from CMD using Dllcall, here is my code:
      #include <WinAPI.au3> #include <array.au3> Global Const $STD_OUTPUT_HANDLE = -11 Global Const $_CONSOLE_SCREEN_BUFFER_INFO = _ "struct;int dwSizeX;" & _ "short dwSizeY;" & _ "short dwCursorPositionX;" & _ "short dwCursorPositionY;" & _ "short wAttributes;" & _ "short Left;" & _ "short Top;" & _ "short Right;" & _ "short Bottom;" & _ "short dwMaximumWindowSizeX;" & _ "short dwMaximumWindowSizeY;endstruct" $pCmd = Run( "cmd.exe" ) Sleep(1000) $hCmd = WinGetHandle("") ConsoleWrite('handle:' & $hCmd & @CRLF) $aRet = DllCall("kernel32.dll", "int", "AttachConsole", "dword", $pCmd) ;_ArrayDisplay($aRet) If $aRet[0] <> 0 Then $vHandle_data='' $vHandle='' $vHandle_data = DllStructCreate($_CONSOLE_SCREEN_BUFFER_INFO) ; Screen Buffer structure $aRet1 = DllCall("kernel32.dll", "hwnd", "GetStdHandle", "dword", $STD_OUTPUT_HANDLE) if not @error Then $vHandle = $aRet1[0] $aRet = DllCall("kernel32.dll", "int", "GetConsoleScreenBufferInfo", "hwnd", $vHandle, _ "ptr", $vHandle_data) MsgBox(0, '1',DllStructGetData($vHandle_data, 'dwSizeX') & _WinAPI_GetLastErrorMessage()) EndIf It did not work, i got the message 'The handle is invalid'. Please help?
      Thank you in advance!
