Hi Joyce,
Thanks a lot, I forgot to include "Shapefil.h" in my code. Now it reduces
almost all my errors, but still I m getting these two errors
SHPEXE fatal error LNK1120: 1 unresolved externals
SHPEXE error LNK2019: unresolved external symbol _memcpy referenced
in function _SHPOpen
I hope you might have solution for this.
What about your NMEA parser, I hope you got what you are trying.
ALL THE BEST and Happy week end,
Keep replying me(helping me),
Cheers,
Venkatesh.

Hi,
To use shapefiles in symbian, i integrated the "shpopen.c" functions from
the "Shapelib" library (U can find information about how to use C in symbian
in the NewLC site),and i called the "shpopen" in my C++ program in symbian
.I could successfully draw the map on the emulator screen.However,when
trying that on the target machine,i am getting the following error:
"Reason code KERN_EXEC
Reason number 3".
Try it and in case u need any help,i will help if i can.

Hi Venkatesh,
Can u please be more specific about the errors u are getting...It could be
syntax errors.Did u include the "Shapefil.h" in your symbian C++ code?.Did u
put the Shapefile u have in the right path (i put it myself under c:\ in
symbian).
P.S:The "SHPOpen" function allows u only to open the ".shp" file.So u have
to specify in the arguments all the path with the name of the file u want to
open.The other argument should be "rb".In case u want to open your ".dbf"
file, u have to use the "DBFOpen" function that is defined in "dbfopen.c".
I hope this will help,but maybe i can be more accurate in case you specify
the kind of errors.
Regards,
Joyce.

Thanks for the advice Frank. As you say the problem is a notional rather
than programming issue. I initially thought that we should standardise on
dBase specifications, but on reflection think its better to go with ESRI
specifications because the dbf table is really part of a composite
shapefile. There is an article at
http://support.esri.com/index.cfm?fa=knowledgebase.techarticles.article
Show&d=18868 which seems to suggest that a null value in a number field
should be returned as VT_NULL while a null value in a string field should
be returned as an empty string "".
Best Regards
Rob
