测试
memo1.text := RunDOS('ping www.baidu.com');
D7改为
b := CreateProcess(nil, //lpApplicationName: PChar
PChar(CommandLine), //lpCommandLine: PChar
nil, //lpProcessAttributes: PSecurityAttributes
nil, //lpThreadAttributes: PSecurityAttributes
True, //bInheritHandles: BOOL
CREATE_NEW_CONSOLE,
nil,
nil,
StartInfo,
ProceInfo);
