Hello everybody,
I have from my console Qt application a .bat file which calls a Windows PowerShell script file. But th exit code is always 1 instead of 0.
Here is the code:
Console App:
QFileInfo fileInf("listFiles.bat");
QStringList arguments;
arguments<< "/c"<< fileInf.absoluteFilePath()<<sFolderName;
QProcess *process = new QProcess();
exitCode = process->execute("cmd.exe ",arguments);
where sFolderName is for example D:\Work
Script listFiles.bat:
cmd.exe /c powershell.exe -noprofile -ExecutionPolicy bypass -file get_filelist_only.ps1 %1
where %1 is supposed to take the value of sFolderName.
Script get_filelist_only.ps1:

[string] $Dir
$currentLocation = $pwd
set-location $Dir
$items = gci $Dir -recurse
# retrieving the list of files
$file_items = foreach ($item in $items) {
if ($item.GetType().FullName.Equals("System.IO.FileInfo")) {
if (test-path "contents.txt")
rm "contents.txt"

function GetRelativePath($fullName)
$len = $currentPath.Length
$len = $len + $lastVersionDir.Length
$relativePath = $fullName
# writing the files
foreach ($item in $file_items)
$relativePath = GetRelativePath($item.FullName)

Out-File -Append -FilePath "contents.txt" -InputObject $relativePath -encoding ASCII

set-location $currentLocation
echo "done!"

So, in fact I am passing the directory argument from script in order to list the files of a directory in the file contents.txt
I have tried from command line cmd.exe /c listFiles.bat D:\Work and it works fine. It calls the PowerShell script and it creates the file contents.txt in D:\Work.
In fact I am arriving in a Qt function:
void QProcessPrivate::findExitCode()
    DWORD theExitCode;
    if (GetExitCodeProcess(pid->hProcess, &theExitCode)) {
        exitCode = theExitCode;
        //### for now we assume a crash if exit code is less than -1 or the magic number
        crashed = (exitCode == 0xf291 || (int)exitCode < 0);
and GetExitCodeProcess is a Windows API function.
which returns exitCode 1. I guess something is wrong with my parameters from my program because on my program console it appears the following:
D:\AutomateTest>cmd.exe /c powershell.ex
e -noprofile -ExecutionPolicy bypass -file get_filelist_only.ps1 D:/Work
'cmd.exe' is not recognized as an internal or external command,
operable program or batch file.
I don't understand what I am doing wrong. Also I have provided the full path for the cmd.exe but it does not work.
Also I have searched on google and on Qt forums but without success.
Thanks for your help.

The environment for the batch process must be missing part, or all, of its PATH variable. Try a different batch script that lists all environment variables to see why.

Thanks a lot for your help. Indeed it was a problem of path. I had to put the entire path to cmd.exe and powershell.exe.
