CallDll return Exit code: -1073741819

[DTNGUYEN]

I have a structure in C++ like this. Please help me to create a structure for this.

struct structAutomobile

(

int flags;/ / -1: all elements of the structure are used / 0xE0 (0b11100000), then only the elements corresponding to the bits of value 1 will be used: nVerbose, strVerboseFile and nStandalone.

int nVerbose;/ / 0: verbose off, 1: verbose is

char * strVerboseFile;/ / Output file (path included) traces (verbose)

int nStandalone;/ / 0: throw srvcomm, 1: do not throw srvcomm

bool bActiveTrace;/ / False: trace inactive true: active track

bool bNoAction;/ / False: The DLL functions are running, true: the DLL functions and does not run API should return Fonction_OK

char * strUserProjectPath;/ / Directory Project

padding1 tank;

padding2 tank;

)

I try this but autoit return ">Exit code: -1073741819"

$str = "int flags; int nVerbose; char strVerboseFile[256]; int nStandalone; byte bActiveTrace; byte bNoAction; char strUserProjectPath[256]";

$a = DllStructCreate($str)

DllStructSetData($a, 1, -1)

DllStructSetData($a, 2, 0)

DllStructSetData($a, 3, "c:\Documents and Settings\dungnt\My Documents\DiamuxV5Data")

DllStructSetData($a, 4, 1)

DllStructSetData($a, 5, 0)

DllStructSetData($a, 6, 1)

DllStructSetData($a, 7, "c:\Documents and Settings\dungnt\My Documents\DiamuxV5Data")

ConsoleWrite("flags: " & DllStructGetData($a,"flags") & @crlf)

ConsoleWrite("nVerbose: " & DllStructGetData($a,"nVerbose") & @crlf)

ConsoleWrite("strVerboseFile: " & DllStructGetData($a,"strVerboseFile") & @crlf)

ConsoleWrite("nStandalone: " & DllStructGetData($a,"nStandalone") & @crlf)

ConsoleWrite("bActiveTrace: " & DllStructGetData($a,"bActiveTrace") & @crlf)

ConsoleWrite("bNoAction: " & DllStructGetData($a,"bNoAction") & @crlf)

ConsoleWrite("strUserProjectPath: " & DllStructGetData($a,"strUserProjectPath") & @crlf)

$rp = DllStructGetPtr($a)

ConsoleWrite($rp & @crlf)

$rc = DllCall($libDiamuxDll, "str", "ConfigureDiamux", "ptr", $rp)

ConsoleWrite($rc & @crlf)

Thank you very much !

Try something like this:

; Input data
$sVerboseFile = "c:\Documents and Settings\dungnt\My Documents\DiamuxV5Data"
$sUserProjectPath = "c:\Documents and Settings\dungnt\My Documents\DiamuxV5Data"

; Structure definition
$tAutomobile = DllStructCreate("int Flags;" & _
        "int Verbose;" & _
        "ptr VerboseFile;" & _
        "int Standalone;" & _
        "bool ActiveTrace;" & _
        "bool NoAction;" & _
        "ptr UserProjectPath")

; Fill the structure
DllStructSetData($tAutomobile, "Flags", -1)
DllStructSetData($tAutomobile, "Verbose", 0)
$tVerboseFile = DllStructCreate("char[256]") ; or maybe in size of the data (+1)
DllStructSetData($tAutomobile, "VerboseFile", DllStructGetPtr($tVerboseFile))
DllStructSetData($tAutomobile, "Standalone", 1)
DllStructSetData($tAutomobile, "ActiveTrace", 0)
DllStructSetData($tAutomobile, "NoAction", 1)
$tUserProjectPath = DllStructCreate("char[256]") ; same comment as above
DllStructSetData($tAutomobile, "UserProjectPath", DllStructGetPtr($tUserProjectPath))

; Set those two
DllStructSetData($tVerboseFile, 1, $sVerboseFile)
DllStructSetData($tUserProjectPath, 1, $sUserProjectPath)

; Call...

Btw, there is difference between bool and boolean.

Thanks for help. I try your code add using the code below

ConsoleWrite("flags: " & DllStructGetData($tAutomobile,"flags") & @crlf)

ConsoleWrite("nVerbose: " & DllStructGetData($tAutomobile,"nVerbose") & @crlf)

ConsoleWrite("strVerboseFile: " & DllStructGetData($tAutomobile,"strVerboseFile") & @crlf)

ConsoleWrite("nStandalone: " & DllStructGetData($tAutomobile,"nStandalone") & @crlf)

ConsoleWrite("bActiveTrace: " & DllStructGetData($tAutomobile,"bActiveTrace") & @crlf)

ConsoleWrite("bNoAction: " & DllStructGetData($tAutomobile,"bNoAction") & @crlf)

ConsoleWrite("strUserProjectPath: " & DllStructGetData($tAutomobile,"strUserProjectPath") & @crlf)

ConsoleWrite("padding: " & DllStructGetData($tAutomobile,"padding") & @crlf)

$rp = DllStructGetPtr($tAutomobile)

ConsoleWrite($rp & @crlf)

It returns

flags: 0

nVerbose: 0

strVerboseFile: 0

nStandalone: 0

bActiveTrace: 0

bNoAction: 0

strUserProjectPath: 0

padding: 0

0

Of course it does. Elements of the structure were renamed. You missed that?

It's not "nVerbose" but "Verbose", etc...

edit: plus that, your AutoIt is outdated. New releases are made for good reasons.
