What is wrong with this code? For some reason, the variables that I set in the Check() function are not set after the function ends. So I lose all my dad after the function returns. if(......) { RaceHorse.BestTime8Furlong.Check(RACE_CLOCK) } Inside the ''BestTime8Furlong'' structure, the Check() looks like this: void Check(RACE_CLOCK race_clock) { iBestTimeMinutes = race_clock.BestTimeMinutes; iBestTimeSeconds = race_clock.BestTimeSeconds; fBestTimeMilliseconds = race_clock.BestTimeMilliseconds; } What am I doing wrong? Thanks. *====================* http://www.syntasoft.com *=======================*

But I''m not setting RACE_CLOCK, I''m setting the other variables. So would that matter?

Need more info I think, if the rest of the code looks like the way I would have made it that little tidbit should work. So I think your problem doesn''t lie in that code.

Is iBestTimeMinutes a member of BestTime8Furlong?

It''s not adequate for diagnosing your actual problem. Are you able to put together a small program that exhibits the problem?

That must be terrible. When was the last time you saw him?

^_^ It looks pretty screwed to me.
presumably RACE_CLOCK is a type, judging by the function definition, so why is he passing a type to the function? I suggest the poster gets himself a book on learning C/C++.

I forgot to mention that the variables:
iBestTimeMinutes
iBestTimeSeconds
fBestTimeMilliseconds

are all members of the ''BestTime8Furlong'' structure.

I am calling the BestTime8Furlong.Check() function to change local variables to the ''BestTime8Furlong'' function.

1. Pass the object by address or reference
2. Pass the object, not the type, as you appear to be doing.

Passing by address (note also, the OBJECT is passed, not the TYPE)

    
//somewhere in the code

RACE_CLOCK rc;

if(......)
{
  RaceHorse.BestTime8Furlong.Check(&rc)
}


void Check(RACE_CLOCK * race_clock)
{
  iBestTimeMinutes = race_clock.BestTimeMinutes;
  iBestTimeSeconds = race_clock.BestTimeSeconds;
  fBestTimeMilliseconds = race_clock.BestTimeMilliseconds;
}

3. Buy a book and learn C++

I thought it was more polite than just RTFM.

By the way, passing the type will not work. I don't know what exactly you're doing wrong, but passing the type is just incorrect. You should either pass a pointer or a reference to the object.

I think I figured it out. I just did it a different way. Instead of using that function, I used another one that is not in the struct.
