Console output from thread - multithreading

Question

I've just started experiencing with thread and can't get some basics. How can i write to Console from thread with interval say 10 msec? So i have a thread class:
public ref class SecThr
{
public:
DateTime^ dt;
void getdate()
{
dt= DateTime::Now;
Console::WriteLine(dt->Hour+":"+dt->Minute+":"+dt->Second);
}
};
int main()
{
Console::WriteLine("Hello!");
SecThr^ thrcl=gcnew SecThr;
Thread^ o1=gcnew Thread(gcnew ThreadStart(SecThr,&thrcl::getdate));
}
I cannot compile it in my Visual c++ 2010 c++ cli, get a lot of errors C3924, C2825, C2146

You are just writing incorrect C++/CLI code. The most obvious mistakes:
missing using namespace directives for the classes you use, like System::Threading, required if you don't write System::Threading::Thread in full.
using the ^ hat on value types like DateTime, not signaled as a compile error but very detrimental to program efficiency, it will cause the value to be boxed.
not constructing a delegate object correctly, first argument is the target object, second argument is the function pointer.
Rewriting it so it works:
using namespace System;
using namespace System::Threading;
public ref class SecThr
{
DateTime dt;
public:
void getdate() {
dt= DateTime::Now;
Console::WriteLine(dt.Hour + ":" + dt.Minute + ":" + dt.Second);
}
};
int main(array<System::String ^> ^args)
{
Console::WriteLine("Hello!");
SecThr^ thrcl=gcnew SecThr;
Thread^ o1=gcnew Thread(gcnew ThreadStart(thrcl, &SecThr::getdate));
o1->Start();
o1->Join();
Console::ReadKey();
}
