I am trying to modify a database record. The element of the record is
derived from the corresponding structure, in which it is designated as
"UInt16" data type. Now I try to use DmSet to write, and have a problem
with "UInt8" data type being required for DmSet.
My code line reads as:
err = DmSet (p, OffsetOf(TransStructType,
BasekVA),sizeof(Record->BasekVA), Record->BasekVA);
This does not cause a crash or a compiler complaint. It simply does not
put the number on the screen that I want. I've been using StrAtoI and
StrItoA to read and write to fields, and these return 32 bit
integers. This hasn't presented any problem, until I try to write an 8
bit integer to a sixteen bit "chunk". The value that comes back when I
write the value to the screen is not the one that I enter. The conversion
process is clearly getting in the way.
Is there another API call to write to an integer in a record that permits
one to write to a 16 bit integer?
DmSet is the same api as MemSet, but for database memory. To write an
16-bit integer, use DmWrite, taking the address of a Int16 variable that
you've saved the value into, and passing the size of that variable in as well.
