[Dev-C++] Object passing itself

[Daniel G. <sp...@ho...>]

Can an object pass itself into the function it is calling?

void DevModeDlg::OnSysCommand( UINT ID, LPARAM LParameter )
{
  try
  {
     DoOnSysCommandWork();
  }
  catch ( Exception &Obj )
  {
     Obj.SetErrorLog( &Obj )           // <--- Here
  }

}



where SetErrorLog

void Exception::SetErrorLog( Exception &Obj )
{
   //... create a text file and put in data contained in Obj.
}

I tried 'this' but b/c I'm inside another class' function it tries to pass 
that object (DevModeDlg)

It seems it should work (though I haven't tried it)... though it beats me
why you should pass in an exception object to an exception method... it
defeats the purpose of OOP, that of every object being self-contained. It
should, I feel, be

Exception::SetErrorLog();

That you wrote:

Obj.SetErrorLog( &Obj ) 


should work (you ommitted a ;).
