DllCall() with C example - struct in call

Recommended Posts

Skysnake
bool SMSAPI_sendsms(
const LPSMSAPI_NETWORKCONFIGURATION lpNetConfig, 
const LPSMSAPI_ACCOUNTINFO lpAccInfo, 
const LPSMSAPI_MESSAGEINFO lpMsgInfo, 
LPSMSAPI_RESPONSEINFO lpResponseInfo);

How does one call this in an AutoIt DllCall() - I do not see "const" conversions and how does one insert the pointers?

You should do something like this.

;~ First declare your structures
Local $tnetworkConfiguration=DllStructCreate($sTagSMSAPI_NETWORKCONFIGURATION)
Local $taccountInfo=DllStructCreate($sTagSMSAPI_ACCOUNTINFO)
Local $tmessageInfo=DllStructCreate($sTagSMSAPI_MESSAGEINFO)
Local $tresponseInfo=DllStructCreate($sTagSMSAPI_RESPONSEINFO)

;~ Set defaults values initialize_defaults

DllCall($h_smstxt32,"bool","sms_initialize_defaults","ptr",DllStructGetPtr($tnetworkConfiguration),"int",DllStructGetSize($tnetworkConfiguration))
DllCall($h_smstxt32,"bool","sms_initialize_defaults","ptr",DllStructGetPtr( $taccountInfo),"int",DllStructGetSize($taccountInfo))
DllCall($h_smstxt32,"bool","sms_initialize_defaults","ptr",DllStructGetPtr($tmessageInfo),"int",DllStructGetSize($tmessageInfo))
DllCall($h_smstxt32,"bool","sms_initialize_defaults","ptr",DllStructGetPtr($tresponseInfo),"int",DllStructGetSize($tresponseInfo))



;~ set some details
$tnetworkConfiguration.nIdealPort = 80;                 //-- use the standard HTTP internet port
$taccountInfo.defaultServerID = (SMSAPI_SERVER)serverID;    //-- connect to the South Africa commerce server
$taccountInfo.szSMSAPIUsername,lpszUsername);       //-- set the bulksms account username
$taccountInfo.szSMSAPIPassword,lpszPassword);       //-- set the bulksms account password   
$tmessageInfo.szMessageText,lpszMessage);           //-- set the message text
$tmessageInfo.lpszCommaSeperatedMobileList = lpszMobile;    //-- set the message recipient list (comma seperated)

;~ then call sendsms

DllCall($h_smstxt32,"bool","sms_sendsms","ptr",DllStructGetPtr($tnetworkConfiguration),"ptr",DllStructGetPtr($taccountInfo),"ptr",DllStructGetPtr($tmessageInfo),"ptr",DllStructGetPtr($tresponseInfo))

Saludos

Thank you kindly, I am playing with your script.  Looks like I was a long way off... Thanks

      Hello All,
      I'm using "ImageSearch2015.au3" and i'm trying to figure out WHY, for the life of me, I can't find an image is hidden.
      So what I came up with, is as follows:
      _ImageSearchAreaHidden("C:\icon.png", 1, 0, 0, 800, 600, $x1, $y1, 80, 0) Func _ImageSearchAreaHidden($findImage, $resultPosition, $x1, $y1, $right, $bottom, ByRef $x, ByRef $y, $tolerance, $transparency = 0) Local $h, $result local $TestScreen = "C:\TestScreen.png" ;previsous screenshot of the image looking for, fully visible If Not FileExists($findImage) Then Return "Image File not found" If $transparency <> 0 Then $findImage = "*" & $transparency & " " & $findImage If $tolerance < 0 Or $tolerance > 255 Then $tolerance = 0 If $h_ImageSearchDLL = -1 Then _ImageSearchStartup() If $tolerance > 0 Then $findImage = "*" & $tolerance & " " & $findImage $result = DllCall($h_ImageSearchDLL, "str", "ImageSearchEx", "str", $TestScreen, "int", $x1, "int", $y1, "int", $right, "int", $bottom, "str", $findImage) If @error Then Return "DllCall Error=" & @error If $result = "0" Then Return False $array = StringSplit($result[0], "|") If (UBound($array) >= 4) Then $x = Int(Number($array[2])) ; Get the x,y location of the match $y = Int(Number($array[3])) If $resultPosition = 1 Then $x = $x + Int(Number($array[4]) / 2) ; Account for the size of the image to compute the centre of search $y = $y + Int(Number($array[5]) / 2) EndIf Return True EndIf EndFunc ;==>_ImageSearchAreaHidden Now when the folder with the icon is completely visible, it finds the icon without any issues, however if I cover up the icon, it no longer finds the image in the folder.
      Any ideas?

      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

      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!
