I'm using Windows 8 with Qt 4.8.4.
Description
Don't know if this would be considered a bug- if it's not please consider it an enhancement request.
I am using QProcess to implement a facility to execute Windows commands like batch files, etc., from within our application. It works quite well, except that I can't use it to execute the command "cmd.exe". No errors, no command prompt window, just nothing. Tracing into the QProcess::start() code, I find this:
DWORD dwCreationFlags = CREATE_NO_WINDOW;
dwCreationFlags |= CREATE_UNICODE_ENVIRONMENT;
STARTUPINFOW startupInfo = { sizeof( STARTUPINFO ), 0, 0, 0,
(ulong)CW_USEDEFAULT, (ulong)CW_USEDEFAULT,
(ulong)CW_USEDEFAULT, (ulong)CW_USEDEFAULT,
0, 0, 0,
STARTF_USESTDHANDLES,
0, 0, 0,
stdinChannel.pipe[0], stdoutChannel.pipe[1], stderrChannel.pipe[1]
};
success = CreateProcess(0, (wchar_t*)args.utf16(),
0, 0, TRUE, dwCreationFlags,
environment.isEmpty() ? 0 : envlist.data(),
workingDirectory.isEmpty() ? 0 : (wchar_t*)QDir::toNativeSeparators(workingDirectory).utf16(),
&startupInfo, pid);
In the debugger I can un-set CREATE_NO_WINDOW and then I can see the DOS window. Shouldn't this at least be settable by a property or something?
I have seen others who have been puzzled by this behavior: http://stackoverflow.com/questions/10363918/qt-cant-launch-windows-console-with-qprocess http://www.qtforum.org/article/28365/open-a-console-program-with-qprocess-and-show-the-console.html
