Hi All,
I try to rewrite some C/C++ code with FPC. I don't know which is the
best string handling technique in this case. The original code for example:
char b_l[b_list_len][bn_len+1];
char s_n[sn_len+1];
I do not want to fight with "char"s or "byte"s. Just want to use the
easier way which

RawByteString still has a dynamic code page. Additionally, operations on
RawByteString are not very well defined by Embarcadero. In general, it
should only be used as a function result or parameter type, and never as

Is it possible to remove or clear items from TFPSList without actually
shrinking the memory (i.e. setting capacity to 0)? Looking the source below I
see every time I clear the list it the capacity is set to 0 also. This is fine
most of the time unless you want to reuse the list without reallocat
I have a question about USB data transfer.. but it's going to take some
explanation...
I've been doing more testing with my device and Libusbxhid. Here's the device:

I have all the inputs working, still have to figure out how to output to the

James,
From the looks of it you made good progress reading the hardware and
using a dedicated thread for it. Congrats! Seems you're in the thick of
it now ready to get the minute details sorted out.
Anyway, just a heads up that concurrent programming (threads,
synchronization, etc) has many

Yeah, I've been wondering that same thing for years. Maybe we should
create a README.1st file. :-P

As far as reading it goes, things are going pretty well.. I still have yet to

Hi James,
are you really sure the WHB04B-6 is exactly the same as your WHB04B-4 viewn to
the USB API?
If those thingys come with a dll, maybe you can compare the header files?
If there is no header file you could ask the manufacturer for it. If they made
a programm using that dll, there must be a
My guess is that it would be better to leave the time sensitive read
thread to do the fast reads and immediate calculations and leave writing
to the device screen in a separate thread (even main thread), with a
lower update frequency!
Yes, that was what I was attempting to describe.. but I can't
They come with a little CD, but not much really useful on them.. mostly
instructions on how to get them to work with Mach3. But the manual does cover
both models. The only difference is one has a selection switch for 4 axis and
the other has one for 6 axis, but the 4 axis version shows 6 axis
My concern was that I could not read and write at the exact same time
