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 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 $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!
I compiled a script I made that takes a command line parameter (the version of a .msi installer) when launched. The script was compiled with the /console option. The script (.au3) works fine but the executable returns the following error:
Error: array variable has incorrect number of subscripts or subscript dimension range exceeded
here's another UDF for the serial port. It is very similar to CommAPI using kernel32.dll, but all code is packed into a single file without any dependencies, not even using WinAPI.au3. It differs from existing UDF that it doesn't allow a timeout when reading, instead it always returns immediately, either with the requested amount ob bytes read or with a failure status. And of course there is a function provided to query the amount of available bytes in the receive buffer. The reason behind this design decision: You can do 1000 other things in the main loop while checking from time to time if enough data bytes arrived. There's no point to block the program waiting for the serial port.
It is currently a work-in-progress, as I didn't test all functions yet. The code was developed and tested on Windows 7 64 bit. The ComUDF-Tests.au3 shows some tests and basic usage of the UDF. Maybe there's no reason to use this UDF, given the existence of the others UDFs, but I did it to get to know DllCall better - I use structs no only to pass but also to get data back (I don't use the array returned by DllCall to read that data, unless required). You're welcome to test it on older and newer Windows versions.
Here's a list of the implemented functions:
; _ComListPorts ; _ComOpenPort ; _ComSetTimeouts ; _ComClosePort ; ; _ComSetBreak ; _ComClearBreak ; _ComGetInputcount ; _ComGetOutputcount ; _ComClearOutputBuffer ; _ComClearInputBuffer ; ; _ComSendByte ; _ComReadByte ; _ComSendBinary ; _ComReadBinary ; ; _ComSendChar ; _ComReadChar ; _ComSendCharArray ; _ComReadCharArray ; _ComSendString ; _ComReadString ; ; __ComClearCommError ; __PurgeComm Maze
I'm currently working a program that constantly prints out log files through "consolewrite" and the "#AutoIt3Wrapper_Change2CUI=y" wrapper.
Part of this program requires me to run a batch script.
My issue is the batch script launches from the same window as consolewrite. I need the batch file to be launched through a different window as currently this causes an issue with the logs (which need to be very precise) but also causes the batch file to produce some funny behavior...
Does anyone know how I can force the file to run on a second DOS window?
Thanks in advance!!!
Edit: Im using the "run" command if that helps. I tried "shellexecute" but that seemed to not launch the batch scripts at all.
I need to start a script that include:
- admin privileges
- multiple cmd commands
- no bat, no exe, no tmp files created anywhere (especially in the user temp folder)
In a bat file it would be simple, but users shouldn't see what commands I'm sending.
Example of the script:
echo off cls echo. echo I AM A TOOL echo. echo NOTE: echo - note 1 echo - note 2 echo - etc set USER1=0 set COMPUTER1=0 if /i %username% equ user.user ( set USER1=1 set COMPUTER1=1 ) if /i %username% equ another.user set USER1=1 if /i %computername% equ notebook set COMPUTER1=1 if %USER1% EQU 1 ( if %COMPUTER1% EQU 1 ( reg delete "HKLM\SOFTWARE\blablabla" /f ) else ( echo Computer not authorized. Contact assistance.) ) else ( echo User not authorized. Contact assistance.) echo. pause exit With the send("") is a disaster.
I'm a noob here, so what can I do?
EDIT: OR ELSE I explain the situation and what I need, so if there is a simple solution I can use that.
SITUATION: our domain users have Users rights on the machine. Some of them need administrator rights.
We create a local user with administrator rights, so that the users must insert username and password when asked to run something with administrator rights.
We have an internal domain group policy that blocks EXE, BAT, COM, TMP files from the user local temp directory, for a security reason (malware). That also blocks most software installation.
But some users are often out of office, away from workplace and in another country, they need a complete control on their computers.
WHAT I NEED: I need to check the username and the computer name. If the username is the one with local administrator rights and the computer name is a computer that is qualified to temporary remove the policy, then I need to execute a REG DELETE command with administrator rights.
I hope I explained myself.
Thank you very much.
