werid issue with C++ functions and default values

[Red Squirrel]

IT's my understanding that if you do something like this:

void DataObject::Load(mysqlpp::Row row,bool childfields=true)
{
//stuff
}

That function can be called without the 2nd argument because I provided a default value. The problem is, I noticed sometimes this works, sometimes it does not (wont compile). Why is that?

Try putting your default values in the function declaration (i.e., in the header), not in the function definition.

Thanks that seems to have done it. I don't know why I thought I had to set it in the function itself. Makes more sense in the declaration. Will also make my life easier as I tend to use my declaration classes as a form of documentation as I see all the function names right off the bat so now I'll see the defaults too without having to comment them separately.
