Hi, I need to time a process within my c++ program, to the finest/lowest level possible (i.e. the smallest fraction of a second possible). I am running my program on a Sun Solaris UNIX machine, and compiling it with g++. I am unable to get what should(?) be simple code to return a meaningful...

Hi, I need to be able to create nested data 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...

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...

hi, I have a rudimentary stack-class implemented in C++ which was working fine until I decided to pull the declaration out into a header file. I now have two files - a header file and a definition file (also containing main()). a snippet of the header is as follows: template <class T> class...

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 = &quot;first&quot;; char* pcSecond = &quot;second&quot;; 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 &quot;Advanced Perl Programming&quot;. Anyway, my command-line is cc codeGen.c -o codeGen -I &quot;/usr/ccs/bin/ld&quot; -I...

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...

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...

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...

Hi, I'd like to automatically launch a Command Prompt window from a script. I've tried to do this and, while there are no errors, a new window does not launch. The command I'm trying to run is C:\WINNT\system32\cmd If I type this in at an existing command-prompt, it returns some...

Hi, I am trying to run a java class in a step in my Ant script, and it does NOT work when I set the variable in an external parm file but it DOES work when I set the variable internally. For example, the following works: <property name=&quot;javac.path&quot...

Hello, I'm sure this question is quite basic, so please forgive me if it is! I am writing a function (call it &quot;f()&quot;) and some supporting data types (structures, unions etc.) that will be used in various other files. I know I shouldn't put the definition of f() in a header file, as...

Hi, I'm a little perplexed about the following... I've seen (and been able to do and work-with) casts along the lines of char** ppcVar; void** ppvVar; ... ppvVar = ppcVar; and all is well.. However, if I have function prototypes void function( char*, char** )...

Hi, I'm using (trying.. to use) Visual C++ 6.0 to compile a bison-generated parser (the x.tab.c file). However, the bison program I'm using generates these .c files with code something along the lines of the following: #line 1 &quot;C:\my\bison\project\home\bison_project.y&quot; The...

Hi, While in the middle of a presentation, IE 5.50 was fired up in order to access a page. The page didn't come up, and when we went to Help to look at the version of IE being used, Version: 0 Product ID: Unknown was displayed. We've tried to replicate this issue since, without...
