It depends on the relative lengths of the then and else clauses. If both are short then I'm more likely to put the true clause first. If one if short (often because its an error case) and the other is long then the shorter one comes first. This makes it easier to determine which if statement a code block belongs to.

For instance
if(statement is false)
  return ERROR_CODE;
else
{
  // Long complicated piece of code
}

in preference to
if(statement is true)
{
  // A really long bit of code
}
else
{
  // By the time you get here its hard to see the iff statement
  return ERROR_CODE;
}

Of course, if both are long (or even if just one of them is long) I'd refactor the long code into functions, i.e.

if(statement is false)
  DoLongComplicatedStuff();
else
  DoOtherLongComplicatedStuff();
