The DataMatrix barcode support is a very intresting features..
The QRCode is not so important.

StSpawn exit code

Bill Florac — Mon, 22 Sep 2003 03:10:47 -0000

Add a "Last Exit Code" property.
By calling GetExitCodeProcess, you can get the last exit
code of an application.

I added this in the TStSpawnApplication.DoOnThreadEnd
procedure just before the notify event is called.

GetExitCodeProcess(FWaitThread.WaitFors^
[0],FLastExitCode);

Subject: For Stephen Posey

Would you please also add a Tag property to TStTextDataRecord?

We just added it to our unit StTxtDat this morning. We needed to have data
processing flags associated with a data record. The Tag property let us
eliminate the code for maintaining a separate array of flags. It was a lot
faster to add the Tag property than to add code for handling the separate flag
array to support insertion and deletion of data records.

property Tag: Longint read FTag write FTag default 0;

We can see that we will use the Tag property for may kinds of run-time
processing of data records (read file in, do various processing on data
records, write file out).

Subject: TStBits to Byte conversion

Hi,
We are using BinaryLS to read a four byte word. we then use TStBits to
change some bit settings. We are trying to read 8 TStBits as a byte to do a
simple byte wide compare. Nothing we have used works. Is there a simple
example somewhere that shows how this can be done.We've used about every
type of pointer and conversion possible on the starting element
TSTBit[element] and the TStBits.Items[element] with no success.

reply:

-------------------->8 cut here 8<--------------------

That last approach will not work, TBitSet.Items is not a true array.

While the desire to do what you describe seems fairly obvious, the
TStBits class doesn't actually account for it directly.

Using the class as-is the only option would be to read the bits
individually and re-construct the bit pattern in a new variable,
something like:

var
Value : Integer;
i : Integer;
begin
Value := 0;
for i := 31 downto 0 do begin
if Bits.Items[i] then
Value := Value or 1;
if i > 0 then
Value := Value shl 1;
end;
...

An alternative is to access the data pointer by opening TStBits'
protected section (using a protected section "cracker class"), this lets
you access the bit data directly:

type
TStBits = class(StBits.TStBits); // cracker class

...

var
Value : Integer;
begin
Move(Bits.btBits^, Value, 4);

I'll also take your question as a suggestion to add a facility to read
and write bit data from from and to other variables, and add that to the
wishlist.

Add ability to set TStTextDataRec's string at runtime

Customer Request:

Wants to be able to set the record data string of a TStTextDataRec at run time
as one unit. Suggests making the .Value property read/write.

This could cause problems if the assigned string doesn't match the provided
schema, so it should be used with CAUTION.

Request for Large File support

customer is working with .5-4gb mainframe text files and finds the Text Data
component's reliance on TStrings is inadequate in those contexts.

Alternatives?

Request for Int64 version of Commaize routine

Present Commaize takes a LongInt parameter, customer has requested a version
that works correctly with Int64 sized values.

Would a Comp version also make sense? How about a BCD or TStDecimal?

Other candidates for large versions:

LongIntForm()
Hex()
Octal()
Binary()
Long2Str()

Hi
Are there functions available for e.g. Str2Cardinal, Str2Single, Str2Double
or do I have to live with the types extended, word and longint?

Can't draw Barcodes to a MetaFile

Customer wants to draw a barcode onto a metafile, the barcode components make
use of APIs internally that are incompatible with drawing to a metafile.

Make metafale the assumption?

Subject: Painting Barcodes to a Metafile DC
Date: Tue, 13 Aug 2002 12:40:41 -0400

I'm having problems painting Barcodes to a MetaFile dc. I have Systools3 and
D5 and I'm calling the PaintToDC method of TStBarCode. Has anyone had succes
doing this or anything similar. I have a similar routine that draws text
elements and lines directly to a TImage using the dc and it works fine. This
routine that I'm having the problem with is creating a metafile to be
printed. All other GDI calls work fine and print correctly.

Subject: Regarding barcodes in a metafile dc - if anyone cares
Date: Fri, 16 Aug 2002 12:43:43 -0400

I was finally able to get a barcode in a memory metafile but not exactly
like the documentation says. I resorted to creating a bitmap, painting the
barcode to the bitmap and then finally bitblting the bitmap to the metafile.
A few points to consider:

1. The barcode control uses calls to DrawText to render the code if ShowCode
is true. DrawText is not a supported WMF or EMF function. It's a user32
function, not a gdi32 function. The GDI attempts to convert DrawText to
combinations of calls to GetTextAlign, SetTextAlign and TextOut (and hence
GetTextAlign, SetTextAlign and TextOut metafile records) but isnt always
successful when doing this with certain DrawText uFormat parameters. The
barcode controls should probably be changed to just call GetTextAlign,
SetTextAlign and TextOut directly which are straight GDI functions and fully
supported in both types of metafiles.

2. The barcode control doesnt not seem to observe any mapping mode you might
have setup for a metafile dc. Once I set ShowCode to false, I could get the
barcode in the metafile but not the size I wanted. The call PixelsPerInchX
:= GetDeviceCaps(Canvas.Handle, LOGPIXELSX); in TStBarCode.DrawBarCode seems
to return a value based on the device units of the metafile reference dc,
not the Window Extents setup in the mapping mode (logical units). This
causes the barcode spacing to be miscalculated and the barcode looks wrong.
I'm not sure whose problem this is, after all, the control is asking for
logical units, not device units. I'm not sure why the dots per inch value is
being returned back as device units. Just my observation.

Enhanced formatting options for Log Strings

Customer Bob Duval has made some suggestions for
formatting strings in the logging components:

I tried to use the TStGeneralLog but discovered it is more of a debugger log
since the time stamp only shows timing. Is there a more generic "general"
log that would allow me to log in a text file various events such as when
the application started or what selection a user made in the format
"mm/dd/yyyy tt:mm:ss LogData". For example:

06/25/2002 01:33:24 Application started
06/25/2002 01:33:45 User Bob logged in

Why don't you offer full control on the formatting of the LogString? Provide
a default string but allow us to reformat it as we want via the
OnGetLogString event handler. This way, older code would work as is, while
new code would benefit from the flexibility.
