The program committee is asking for papers and presentation proposals from anyone using or developing with Tcl/Tk (and extensions). Past conferences have seen submissions covering a wide variety of topics including: * Scientific and engineering applications * Industrial controls * Distributed applications and Network Managment * Object oriented extensions to Tcl/Tk * New widgets for Tk * Simulation and application steering with Tcl/Tk * Tcl/Tk-centric operating environments * Tcl/Tk on small and embedded devices * Medical applications and visualization * Use of different programming paradigms in Tcl/Tk and proposals for new directions. * New areas of exploration for the Tcl/Tk language Submissions should consist of an abstract of about 100 words and a summary of not more than two pages, and should be sent as plain text to no later than August 27, 2012. Authors of accepted abstracts will have until October 29, 2012 to submit their final paper for the inclusion in the conference proceedings. The proceedings will be made available on digital media, so extra materials such as presentation slides, code examples, code for extensions etc. are encouraged. Printed proceedings will be produced as an on-demand book at lulu.com The authors will have 25 minutes to present their paper at the conference. The program committee will review and evaluate papers according to the following criteria: * Quantity and quality of novel content * Relevance and interest to the Tcl/Tk community * Suitability of content for presentation at the conference Proposals may report on commercial or non-commercial systems, but those with only blatant marketing content will not be accepted. Application and experience papers need to strike a balance between background on the application domain and the relevance of Tcl/Tk to the application. Application and experience papers should clearly explain how the application or experience illustrates a novel use of Tcl/Tk, and what lessons the Tcl/Tk community can derive from the application or experience to apply to their own development efforts. Papers accompanied by non-disclosure agreements will be returned to the author(s) unread. All submissions are held in the highest confidentiality prior to publication in the Proceedings, both as a matter of policy and in accord with the U. S. Copyright Act of 1976. The primary author for each accepted paper will receive registration to the Technical Sessions portion of the conference at a reduced rate. Other Forms of Participation The program committee also welcomes proposals for panel discussions of up to 90 minutes. Proposals should include a list of confirmed panelists, a title and format, and a panel description with position statements from each panelist. Panels should have no more than four speakers, including the panel moderator, and should allow time for substantial interaction with attendees. Panels are not presentations of related research papers. Slots for Works-in-Progress (WIP) presentations and Birds-of-a-Feather sessions (BOFs) are available on a first-come, first-served basis starting in August 6, 2012. Specific instructions for reserving WIP and BOF time slots will be provided in the registration information available in June 2012. Some WIP and BOF time slots will be held open for on-site reservation. All attendees with an interesting work in progress should consider reserving a WIP slot. Registration Information More information on the conference is available the conference Web site (http://www.tcl.tk/community/tcl2012/) and will be published on various Tcl/Tk-related information channels.

Re: [sqlite] C# Dynamic data type
You can use sscanf to determine data type...I've done it before using a method
that's not obvious...
You parse from most restrictive to least restrictive format like this...this
will accept any valid float format including scientific notation.
#include
enum {UNKNOWN, FLOAT, INT, STRING};
int datatype(char *s)
{
long i;
double f;
char buf[4096];
int n;
n = sscanf(s,"%d%s",&i,buf);
if (n == 1) {
printf("INT\n");
return INT;
}
n = sscanf(s,"%lg%s",&f,buf);
if (n == 1) {
printf("FLOAT\n");
return FLOAT;
}
n = sscanf(s,"%s",buf);
if (n == 1) {
printf("STRING\n");
return STRING;
}
else {
printf("UNKNOWN\n");
return UNKNOWN; // should never get here
}
}
main()
{
char *line1="1234";
char *line2="1234.5";
char *line3="x1234.5";
datatype(line1);
datatype(line2);
datatype(line3);
}

Subject: EXT :[sqlite] C# Dynamic data type
Good day,
I've been reading a bit of conflicted stuff online in terms of data type.
The most basic question, in C#, is can you easily determine the data
type of the Nth entry in a column.
{Ex: Create table A( x TEXT, y )
... a few inserts, binding a float, then a string, then an int into y..
select x,y from A
check the type of y before retrieving a value from it.
}
The docs for SQLiteDataReader.GetFieldType() seems to read as if it
will return the column affinity.
regards,
Adam

Re: [sqlite] Suggestions for approximate date
I'd vote for the date-range as that can be indexed and result in fast retrieval. The separate column for accuracy would be a computed range and not indexable. Michael D.

[sqlite] Fw: Fw: Fw: A question on sqlite processing
Dear sirs,
My group is working with SQLITE Version 3.7 . .and the project has to do with
transformation of applications
to run on a Bare PC. On a CREATE TABLE, our traversal, in terms of
opcodes, inside sqlite3VdbeExec() is something like 1, 22, 25, 1, 23, 1a, 7,
24, 7, 24, 62, 27, 36, a, 37, 2b, 2b, a, 27, 15, 4a, etc. A parallel session
on Visual Studios gives the same sequence but has opcode 34 instead of the
highlighted 4a.
Can you, out of your expertise with SQLITE tell us what could cause this
difference,? Any clue would help. In
going from one opcode to another, what is there to watch for, that may alter
the opcode value, p1 value, p2 value
or p3 value? If at all possible, I would like to speak offline with some
developer in your group so I can describe a
few more of our observations - my cell is (973) 332 0997,
Best Regards,
RKKUZO

Why don't you try the split yourself and see if it solves the problem and then
let us all know?
It sure sounds like file size could be the cause.

Is that to say that the 'split on the source file' that is yet to be made is
the reason
for the branching described below (see highlighted below) - can you, please,
explain further, I am still lost? That question still remains a question,
please help . . .
And now, another . . if you don't mind . .
when I tried to set a breakpoint at the definition (in sqlite3.c file) of the
function,SQLITE_API
u8 state = 0; intsqlite3_complete(constchar*zSql){/* Current state, using
numbers defined in header comment */u8 token;
not currently be hit. No executable code is associated with this line. Possible
causes include: preprocessir directives or compiler/linker optimizations.
I would really like dislodge/remove as many of the preprocessor directives and
options for compiler/linker optimization as possible. Mine is a search
project;
I need to strip off the sophistication used all over to have just the bare
application.
Can you help me?

This was just answered in another chain. Visual Studio has a 64k limit on
source code files for the debugger (thanks Microsoft...a 16-bit
limit?...really!).
If you need to step into it use WinDbg
http://msdn.microsoft.com/en-us/windows/hardware/gg463009
Nobody has done a split on the source file yet to make it < 64k.

Dear sir,
I have built a project solution in Visual Studio environment (version 10) using
a free
amalgamation source down from SQLite website and I am debugging. My first
question is - when I invoke sqlite3_complete() out of the shell.c source file,
control
passes into the body of sqlite3PagerSetPageSize(Pager *pPager, ..) function, a
method defined in sqlite3.c file (rather than going to a function defined in
sqlite3.c
file as sqlite3_complete()). please explain this phenomenon and the reason
behind
it . . . it's a similar occurrence also with sqlite3_config.
It is consistent and obviously with a reason - only I don't know what that
reason is,
please help
Yours truly,
uzo okafor
