QT通过名称杀进程

bool ClassName::KillProcessFromName(QString ProcessName)

{ 

bool result = false;

QString str1;

HANDLE hSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0) ; 

PROCESSENTRY32 pInfo; 

pInfo.dwSize = sizeof(pInfo);

Process32First(hSnapShot, &pInfo);

do 

{

str1 = (QString::fromUtf16(reinterpret_cast(pInfo.szExeFile)));

if (str1 == ProcessName) 

{

result = true;

QString cmd;

cmd = QString("taskkill /F /PID %1 /T").arg(pInfo.th32ProcessID);  

//![0]此方法很有效,但是会弹CMD的命令框

//system(cmd.toAscii());

//![0]

//![1]此方法很有效，解决了弹出CMD命令框的问题

QProcess *process = new QProcess;

process->start(cmd.toAscii());

//![1]

} 

} while(Process32Next(hSnapShot, &pInfo) ); 

return result;

}
