Chris,
How are you coupling your Rose models with your Delphi code? Does
Rational support Delphi, or are you using some third party add on? And
if a third party add on, can you please tell us a little about it (such
as a web address, price, and general quality)?
Thanks

Hi all,
Copying files in Delphi is not a problem. Showing
the progress of the copying on a progress bar seems to be more
difficult.
If any of you can properly describe the process I'd
be delighted.
Cheers and Merry Xmas

Hi all,
I have a job coming up early next year which will require accurate timings
for process control down to 1ms.
The customer already has a dll for VB which covers this, but of course I
will be doing this job in Delphi.
Any pointers to api's, components etc would be appreciated.
thanks,
If you use SHFileOperation doesn't the standard Windows animated progress bar show
automatically?

The API function CopyFileEx has a callback function for displaying progress.
The other way to do it to open a FileStream on source and on target and copy
between them yourself - you can track progress as you go.

Hi
I'm converting my Application from Paradox to Interbase. I don't
want to change anything in my Application code, hence I have to
modify TIBTable to include some functions. They are

2. CancelRange
3. FindNearest
4. FindKey
5. SetKey
How do I go about implementing them in
File based and SQL based databases are just not the same - usually require a
major rewrite to work with SQL databases to get similar performance.
Your best bet would be to derive your own table and for each of the cases
outlined generate/create/write your own SQL statements.

It is possible to lock a record using FIB TDataset.
Table.LockRecord is used to lock a record. When the LockRecord
function is called an update query is executed.
And what does this 'update query' do? All I was stating was that SQL
does not expose the concept of record locking
You can use sets - they are fast but may still be limited to 256 bits
(or 8 bytes).

You can write your own copyfunction - look at borlands fmxutils.
Or, one of the shell extensions supposedly have a callback to allow
you to do a progress bar... The problem is that it only supports
one filemask... which is dratted useless for our purposes.

Now commit the transaction.

It stores it at the bit level.
ie a packed array of physical bits.
Looking at the Get method.
The BT (Bit Test) instruction moves the reference bit into the carry flag.
The SBB moves this into the first bit - the AND is not necessary in my
opinion.

Don't worry about the assembler code - that just sets and gets the bits.
Looking in the source for TBits.SetSize we see
NewMemSize := ((Value + BitsPerInt - 1) div BitsPerInt) * SizeOf(Integer);
where BitsPerInt = BitsPerInt = SizeOf(Integer) * 8;
Sizeof(Integer) = 4 on my system, so

Are the arrays large with only a few true values? If so a sparse array

Import the functions from the DLL into Delphi? This should be easy enough

If INNER JOIN is introduced in PostGre 7.1 then why isn't it documented in
the 7.1 documentation?
(And I don't mean a pseudo-join created using a comma, for goodness sakes!
What about left and right joins?)
