<![CDATA[Using wmic to get info]]>I'm making a QT application to retrieve info from OS.I'm trying to access wmic.exe directly ( i added the path Windows\System32\wbem\ previously in the code ) and i don't want to use it through cmd.The code works fine in Windows Vista/7 but doesnt work in Windows XP

Sample code :

@ QProcess process;
process.start(QString("wmic bios get serialnumber"));
process.waitForStarted();
process.waitForFinished();
qDebug()<<process.readAll();
system("pause");@

Note : I'm using QT 4.6

Any Ideas ?

This is part of working function from my app:

@...
QString Arguments = "/node:" + IP + " " + Args + " get /format:list";
...
Process.setProcessChannelMode (QProcess::MergedChannels);
Process.start ("wmic");
Process.waitForStarted ();
Process.write (Arguments.toUtf8 ());
Process.closeWriteChannel();

while (Process.waitForReadyRead ())
{
while (Process.canReadLine())
{
...@

In win xp it just shows the console dash like forever no results are shown and program never ends while in win vista/7 normal results are shown.

I tried removing system("pause") same issue.
