Adobe Air - native process communication with exe fails - c++

Question

I'm struggling with Adobe Air native process communication. I'd like to pass an c++ exe shellcommands stored at processArgs when started. The c++ program uses this arguments to choose device channel and symbolrate of an CAN-Bus-Adapter. The c program itself creates an json database for an html page. While the c program is processing i'd like to get some feedback of the program and if it exits adobe air should create a link for the html page with the function onExit. The c program uses standart output of iostream lib ("cout", "cerr") to send messages to adobe air.
Adobe Air script:
var process;
function launchProcess()
{
if(air.NativeProcess.isSupported)
{
setupAndLaunch();
}
else
{
air.Introspector.Console.log("NativeProcess not supported.");
}
}
function setupAndLaunch()
{
var cpp_device = $( "#device option:selected" ).val();
var cpp_channel= $("#channel option:selected").text();
var cpp_symbolRate= $("#symbolRate option:selected").val();
air.Introspector.Console.log("CHANNEL",cpp_channel);
air.Introspector.Console.log("Device",cpp_device);
air.Introspector.Console.log("Symbol Rate",cpp_symbolRate);
var nativeProcessStartupInfo = new air.NativeProcessStartupInfo();
var file = air.File.applicationDirectory.resolvePath("InteractiveDocumentation.exe");
nativeProcessStartupInfo.executable = file;
var processArgs = new air.Vector["<String>"]();
processArgs.push(cpp_device);
processArgs.push(cpp_channel);
processArgs.push(cpp_symbolRate);
nativeProcessStartupInfo.arguments = processArgs;
process = new air.NativeProcess();
process.start(nativeProcessStartupInfo);
process.addEventListener(air.ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
process.addEventListener(air.ProgressEvent.STANDARD_ERROR_DATA, onErrorData);
process.addEventListener(air.IOErrorEvent.STANDARD_OUTPUT_IO_ERROR, onIOError);
process.addEventListener(air.IOErrorEvent.STANDARD_ERROR_IO_ERROR, onIOError);
process.addEventListener(air.NativeProcessExitEvent.EXIT, onExit);
}
function onOutputData(event)
{
air.Introspector.Console.log("Got: ", process.standardOutput.readUTFBytes(process.standardOutput.bytesAvailable));
}
function onErrorData(event)
{
air.Introspector.Console.log("ERROR -", process.standardError.readUTFBytes(process.standardError.bytesAvailable));
}
function onExit(event)
{
air.Introspector.Console.log("Process exited with ",event.exitCode);
$("#output").html("Start");
}
function onIOError(event)
{
air.Introspector.Console.log(event.toString());
}
$(function()
{
$("#start").click(function()
{
air.Introspector.Console.log("START");
launchProcess();
});
});
the c program is quite long, and here i post only the main part
int main( int argc, char *argv[])
{
//! get shell commands for init
// echo shell commands
for( int count = 0; count < argc; count++ )
{
cout << " argv[" << count << "] "
<< argv[count];
}
// handle data
intDevice = (int)(argv[1][0] - '0');
intChannel = (int)(argv[2][0] - '0');
intChannel -= 1;
intSymbolRate = atoi(argv[3]);
//! class function calls
useDll CanFunction;
try
{
CanFunction.initProg();
CanFunction.ecuScan();
CanFunction.openSession();
CanFunction.readECU();
CanFunction.stopProg();
return 0;
}
//! exception handling
catch(int faultNumber)
{
....
}
}
First I used only the onExit listener and everything works fine. After I used start conditions adobe air only responses if i call no class functions except the CanFunction.initProg() and the onExit function was called but skipped the jQuery command to create the link. If I add the class function calls, the c program is called and the json database created but Adobe Air doesnt received any responses. The json database is still created. This confuses me.
My c program uses some *.dll files to communicate with the bus so i could imagine that it is a windows problem. But it is still weird.
Has anybody an idea why adobe air communication doesnt work with my c program if i call my class functions or why the jQuery command is skipped?
Or is there a better solution to call a c++ exe from adobe air?
