    Possible memory leak

    Sorry, but what do you mean by "Class std::string has value semantics"?

    Possible memory leak

    It seems to me that you have a C background. Right? That's why you feel uneasy about this approach. It is strange indeed. Thanks for the answer.

    Possible memory leak

    In the following class I'm using the C lib <time.h> . The functions gmtime, ctime, and asctime return pointers to char/structs. Am I responsible to clean the memory allocated by them? Is there any possible memory leak associated to the methods MyTimeClass::getDateAndTimeLocalTime() and...

    There are 4 tables defined in this MIB: - Config Table: which holds configurations profiles for named Logs. -Stats table : which holds statistical data for each named log. -Log table: which holds the actual log entries for each named log. - LogVariableTable: which keeps track of log table...

    Inject data into a struct

    Thanks Scott, but that’s the point. I can’t change things like that. Unfortunately this is a legacy code and I need to figure out a way to use those structures as they are. Would be very nice to have u_int8_t *data instead of u_int8_t data[MAX_DATA_SIZE]. Best Regards, P.

    Inject data into a struct

    ...}; typedef struct b_s b_t; At some point, the received info is routed to another equipment using the following functions: int checkSet(void * ne, b_t * msg) { (…) send(ne->position, msg->payload.cmd, msg->payload.dataSize, msg->payload.data) (...) } int send(u_int8_t pos...

    set a vector inside a struc to NULL

    That wouldn't cause some memory leak? Since it's automatically allocated a chunk of memory of u_int8t * MAX_DATA_SIZE bytes?

    code error?

    Here is an excerpt from one tutorial on how to compare float numbers in C: "(...) It is very usual for the C programming language beginners to compare a floating point number using the "==" operator. Floating point numbers must not be compared with the "==" operator. That is mainly because...

    set a vector inside a struc to NULL

    Given the following scenario: struct a_s{ u_int16_t cmd; u_int16_t dataSize; u_int8_t data[MAX_DATA_SIZE]; }; typedef struct a_s a_t; struct b_s { u_int16_t part; u_int16_t serial; a_t payload; }; typedef struct b_s b_t; (...) b_t message; how can I set...

    Function definition with multiple '( )'

    Thanks for the reply. It turned out that the 'func(pu)' was actually a macro. Regards.

    Function definition with multiple '( )'

    Hi, Is that a function definition? Why there are 2 sets of '()' in the definition and in the call? What's the name of this kind of definition? Definition: static inline void func(pu) ( void ) { printf( "%s", s_msg_usage ); } Call: func(pu)(); Thanks.

    drawing b-tree on canvas (multiway tree)

    Does anyone have a algorithm for drawing a b-tree (a multiway tree, not a binary tree) on the canvas? I'm having a really hard time trying to do that! Thanks, Best regards, Paul.

    link lib file

    Thanks Steve, but how about the dll? do I have to include it somewhere? Maybe set a path? I've put the dll in the same project's folder, but the linker cannot find it. Every time I run I got a message of missing dll. Thanks again, Best Regards, Paul.

    How do I link a lib file to my project? Where do I set the path to the lib file? Thanks, Best regards. Paul.

    load dll lib

    I'm having a hard time to use a third party sound engine dll. How do I load the functions from the dll to use them as if they were in a normal unit(*.c/*.h)? I've already got the right .lib for c++ builder. But how do I load it? Best Regards. Paul.

    Disable mouse click.

    That was a great idea.

    Disable mouse click.

    Yes. That was the solution I used to this problem. Should have posted here... Very straight-forward, but you need to do some tricks to get rid of the "grayed text". A good solution though.
