[Qt-interest] QProcess problem when argument has space in windows Qt 4.5

[Hari Panicker]

Hi all

I am using Qt 4.5. I am trying start a msi install by calling msiexec.exe using QProcess. I am passing the path of the msi which has spaces in the path. I do put them between quotes. It just does not work... here is the code below

int SetupWrapper::startProcess(QString args)
{
QString program = "msiexec.exe " + args;
QProcess *myProcess = new QProcess(this);
myProcess->start(program);
myProcess->waitForFinished(-1);
int errorcode=myProcess->exitCode();
myProcess->close();
return errorcode;
}

void hari(...)
{
int res = startProcess("/i \"C:/New Folder/Dummy.msi\" MSIS=\"|C:/Documents and Settings/hari/Desktop/setup/store.msi|C:/Documents and Settings/hari/Desktop/setup/Tool.msi\"");
}

I even tried replacing \" with \"\"\" when argument has spaces after looking at this site
http://doc.trolltech.com/4.1/qprocess.html#start-2
like below....
void hari(...)
{
int res = startProcess("/i \"\"\"C:/New Folder/Dummy.msi\"\"\" MSIS=\"\"\"|C:/Documents and Settings/hari/Desktop/setup/store.msi|C:/Documents and Settings/hari/Desktop/setup/Tool.msi\"\"\"");
}

Nothing seems to work.... the msi does not get executes.. msiexec gives out error arguments wrong...

is this a bug or am i doing something wrong??? 

thanx 
Hari

Note: i tried this is C# and it works perfectly....
