"PostMessage" without window

[C++ Programming]

End Google Ads 201810 - BS.net 01 --> We can use PostMessage() to post integer to HWND if a window handle is valid, but how to post a message to a class object if without HWND?

The story looks like:


MyClass my;

void MyClass::Send()
{
post_message(100);
}

void MyClass::Receive()
{
switch(...)
{
case 100:
....
break;
}
}



how to implement the user function post_message(100)?
