how check if given field name exists in access database table using vc++ daorecordset. tried google , msdn documentation find useful. i tried following code: bool isfieldexixts(cdaorecordset *rs, cstring fieldname) { colevariant ov; try { rs->getfieldvalue(fieldname,ov); } catch(cdaoexception e) { return false; } return true } but instead of raising exception when not found, displays messagebox stating item not found. i need c++ solution, can find on google vb solutions getfieldvalue not display messagebox. catch block not correct, need catch(cdaoexception *e) { e->delete(); return false; } so in program exception not handled in code. in mfc top level function default handler exceptions invoked , 1 displaying messagebox. btw, check if entry exists in recordset can call cdaorecordset::iseof .

i've found guides on programmically getting random numbers generate normal; however, need spread out number reflects normal distribution (in least calculation time possible). for example, have item cost $500,000 in year 2050 , spread across standard deviation of 20 years. result in area under first standard deviation (year 2030 2070) having (68% * $500,000) of cost. is there formula can use in code achieve this? way can think of right using box muller random generator , loop through each dollar generate distribution, not efficient. note total value under normal distribution 1. therefore, need find out percentage of curve accumulates in timeframe , multiply total cost. instead of normal distribution, want normal cdf (cumulative density function) ( here in c# ). so, sum up: find cost given range of years, find normalized values years, plug them cdf function, , multiply total cost: start = (start_year-0.5-median)/stddev; end = (end_year+0.5-median)/stddev; cost ...

this question has answer here: addition of 2 pointers in c or c++ not supported. why? 3 answers i going through c pointer arithmetic. found pointer addition not allowed pointer + integer allowed. i thought pointer + pointer not allowed due security reason. if pointer p1 holds 66400 , p2 holds 66444 . p1+p2 not allowed p1+66444 allowed. why so? think way. address 1: 112, bakers street address 2: 11, nathan road why address1 + 3 fine address1 + address2 bad. (btw address1 + 3 mean 115, backers street) for same reason multiplication of scalar or address address doesn't make sense. address1 * 2 // invalid address1 * address2 // invalid logically possibly take offset address adding/subtracting adding 2 addresses doesn't make sense because addresses of same variables may different in each run of program. type , value of addition don...

we have 6 wsdls compiled within same project, , due limits of hardware can open 1 port listening. for doing this, choose approach described chapter 7.2.8 how chain c++ server classes accept messages on same port in gsoap manual . however, when using approach in encounter many sever issues: 1. if lots of requests arrive concurrently, soap_begin_serve reports error error=-1, socket closed soap server after established 2. if call xxx.destory() after soap_free_stream(), soap_accept() report error of bad file descriptor , not work anymore (solved) anybody knows reasons of above phoenomenon? how solve them? our code close example except few changes, see below section. //server thread abc::soapabcservice server; // generated soapcpp2 -i -x -n -qabc server.bind(null, 12345, 100); server.soap_mode = soap_keep_alive | soap_utf_cstring; server.recv_timeout = server.send_timeout = 60; while (true) { server.accept(); ... pthread_create(&pid, null, ...

i need extend c++ app python scripts i'm unsure interface library should use. basic communication is: c++ app registers class methods script (so loaded module in script), calls specific function in python script. script should perform task while being able call c++ methods. when script has finished, c++ app should able use return value of script (e.g. std::list). from i've read boost.python pretty powerful , considering fact use boost, seems way go. in documentation, have not seen way expose class methods (static or not) python script. is possible? how can that? edit : ok, think should have been little more specific, sorry. know how import python libraries etc. c++ code , i've taken boost documentation regarding embedding didn't got looking for. for clarity, workflow in scenario: c++ app starts running at point, c++ class needs support specific python script located somewhere @ defined plugin-location on hard disk. before calling script, c++ class wan...

in mfc application, afxoleinit() method called in application initinstance() method. need call method because using ole objects in application. i using dll doesn't work if afxoleinit() has been called. i thinking about: calling afxoleterm() prior loading dll, doing have dll, calling afxoleinit() afterwards (in main program, not in dll). is acceptable solution? note in practice, if this, dll behaves properly. calling afxoleterm prior dll calls no idea. reason simple: doing may cause created com objects thread destroyed, or nay not accessible longer. anyway calling afxoleinit inside dll no idea. problem is, call specific thread. only application should call afxoleinit in thread , should perform further action. and make more complicated, depends on model of mfc using. sharing mfc in dll cause afxoleinit act different using statically linked dll.
