Hi all.
Will sizeof(somestring) always be 9 bytes larger than high(somestring)/getstringcapacity(somestring)? Or is it just in one case I have found this...

A string contains Capacity and Length (4 bytes each on a 32 bit platform) and an extra character for the #0 when converting to CString.

OK, thank you... Is it converted to CString automatically when calling sizeof? Because it is 9 bytes longer than getstringcapacity...

Not converted, but the extra char is always there (so that it's available when it's needed).

On ix86 platforms the allocation is rounded up to a multiple of 4 bytes. Thus string( 1 ) is 12 bytes, not 10. Only significant if you have a lot of strings and limited memory.
