...to get what should(?) be simple code to return a meaningful answer. example:

#include <time.h>

int main( int argc, char* argv[] )

time_t t2 = time(0)...
Thank you for your reply,
This leads to the following question...
is it possible to store in a map values of different map-types?.. (e.g. map<int,int>, map<string, string>, etc.)
I think the answer is probably no, but am not sure. Perhaps I've been living in the world of weak-typed scripting...
...structures in C++, e.g. maps of maps (maps with values being maps). I'm not sure how to do this...
I've tried:
#include <map>
map<string, map* > m;
and other such combinations, to no avail. I know this has to do with the fact that map is a template, but I'm not sure how to work around...
Hi,
I've been working on a project in Python, but it has turned out to be too slow to handle the volume of data I need to work with. For my project, I've been using DBM tools (specifically, CDB) and object serialization - essentially creating a DBM file with values consisting of serialized...
Hi,
I'm trying to use dynamic pl/sql in a pro*C application (environment = HPUX Oracle 9i), and am encountering problems when I try to use cursors. Evidently it IS possible to use cursors in this way - after googling I found several examples which provided the foundation for my efforts.
The...
...if I follow the same procedure but with non-template classes.
This is very frustrating - what am I missing or doing wrong? This is a simplified version of something I'm doing for work. We unfortunately have no C++ people here, other than me.
ANy help *very* appreciated,
Thanks :,(

Hi,
I have a file of functions I want to object-compile, rather than use to build an executable. I would like to do this so that the .obj file that results can be used in the compilation of other executables. I am compiling my program (using the VC++ 6.0 command-line compile facility, vs. the...
Hi,
I was perusing the Panther book (advanced perl programming), and noticed that, in a particular example, the author does the following:
package Object Template;
require Exporter;
@ObjectTemplate::ISA = qw(Exporter);
@ObjectTemplate::EXPORT = qw(attributes);
My questions are:
1) package...
Hi,
I'm sure there is a simple explanation for this, but it is frustrating me. This code:
#include <string.h>
void main()
{
char* pcFirst = "first";
char* pcSecond = "second";
char* pcConcat = strcat( pcFirst
,pcSecond )...
Hi,
I've build a perl executable, but when I run it I get the following error-message
Can't load module File::Glob, dynamic loading not available in this perl.
(You may need to build a new perl executable which either supports
dynamic loading or has the File::Glob module statically linked...
Hi,
I'm trying to embed the Perl interpreter into a c program on our HP9000 UNIX server. I'm following the examples in "Advanced Perl Programming". Anyway, my command-line is
cc codeGen.c -o codeGen -I "/usr/ccs/bin/ld" -I...
Thanks for the reply!
So, my efforts to -I include those libraries when I was doing my cc compile AFTER I had run the make file to produce the .c file were in error... I should be including that IN the make file.
Does anybody have a good, sample makefile that would allow me to produce only...
Hi,
I'm doing the following on a HP9000 Unix server...
I have two c source files I need to compile together - one is output from the pro*c precompiler (call it ProC.c), and a non-precompiled c source file (call it Prog.c - no main(), just functions).
When I compile this as follows:
cc -I...
That's really in my code... they're actually different variables but point to the same address.
Sorry about that - I was trying to slice my code down to something postable and understandable and forgot that...

Hi,
I am requesting arrays of free-store memory as follows:
ppvMemoryBlock =
( void** )calloc( iSize
,sizeof( void* ) );
am referencing it (after allocating the
constituent void* values) as follows:
myFunction( *(ppvMemoryBlock + iArrayCounter) );
Both of which work fine...
Hello Mactonio,
Thanks for the reply.
Which Oracle driver are you using - the "DBD::Oracle" driver? I first tried to use an Oracle driver I already had on my PC (the one I reference above), but that didn't work. I went to CPAN, and DBD::Oracle looks promising. However, when I...
Hi,
I'm trying to connect to our Oracle9 database via the Perl DBI (I'm using ActiveState Perl, and installed the DBI and DBD::ODBC via the ActiveState ppm).
Here's my basic connection attempt:
use DBI;
$DSN = 'driver={Microsoft ODBC for Oracle};database=MyDatabase';
$DBH = DBI->connect(...
Hi,
I need to use strcat() to concatenate two strings, call them sFirst and sSecond. sFirst is allocated as follows:
char* sFirst = (char*)malloc( sizeof(char) );
sSecond is allocated in the same way. I concatenate them
as:
sFirst = strcat( sFirst, sSecond );
Now, the literature I've...
