Morning all,
It feels great to be back working again, and try as I might I
simply cannot find any faults with the CodeGear release of Delphi 2007!
Great job guys!
Anyway, my current project involves a groups of methods that
control a digital clock, up and down Timer, and a Calendar, and provides
the user with multiple ways of using sounds and counting procedures for
alarms and such.
Two areas I wish to ask about.
The first is in regards to playing a simple sound file, ( Wav ),
at one second intervals. Right now after trying some of the related
methods and parameters, I'm using 'PlaySound(PChar(SelIntervalWavFile),
0, SND_ASYNC);' and a wav file that just plays a beep. Other methods
related to this one either cycle out of synch or skip seconds, and
though this one seems to keep up with my timing event, the first couple
beeps play late. I'm not sure where the majority of the problem lies,
but I believe it's due to having to load and re-load the file. Is there
anyway of loading such a file into memory before the countdown begins
and stays there so that this problem is eliminated? Should I not use a
wav file, a simple system beep in place of it to guarantee good
synching? Is PlaySound from mmSystem the problem? Is there a better
way? Unless someone has a better solution, I'm thinking now of just
using the system Beep for the interval sound and then a custom wav file
at the end of the timing period.
The second question regards the timing method itself. At
present I'm using a Clock/Calendar panel from Raize to display for some
of the methods and a Raize digital control for simple up/down counting.
Either is displayed in place of the other as required at the moment, but
the Clock/Calendar has it's own OnTimeExpired event which can be set
down to 500ms. For one second timing as displayed on the digital
control, I'm also using this same event and counting by 2's. I don't
necessarily need anything more accurate, but efficient would be the word
I would choose. Is there a better freeware timer component out
there I haven't found that might help? And should I keep my timing
methods in their own thread?
Lastly, I'm having difficulty with only one set of
components...those from TMS. I have the latest update files, 4.3, for
this version of Delphi, but I'm having a problem trying to compile the
new packages that is quite odd. I've already contact them about this
but so far they only been able to offer the same solutions I've already
tried. There are no registry entries or loose bpl's lying about my
system, but every time I attempt to compile a dpk or open the entire
project containing all of them and click Open, I get an error for the
first dpk which has a filename of TMSd2007.dpk, and then every other
package as well. It says, "Unable to access TMSd2007.$$$" I figure
that's a temp file it needs to create because none exists with that
extension in the source code, and I have made sure all directories and
source has write access. Could there be a temp dir on my system
somewhere that it is trying to use? Any ideas?
