Hi, I want to be able to test if a string is numeric. Kind of like the isNumeric() function in VB6. Has anyone got any ideas how to go about this? Ive tried using isdigit() and isalnum() but both require an int as a parameter and i want to test a string. Thanks alot PS It has to be portable...

Thanks guys, most informative as ever! CRule(vRules[i]) is the constructor of the object i am creating and as you can see it is only being called in the vector and as a result I should hopefully not have to do anything about it. Smart pointers? Does anyone have any good links? Thanks

Hi, Im concerened with memory leaks when deleting objects from vectors i.e. I am adding objects to the vector like such <code> for(i = 0; i < vRules.size(); i++) { _vRules.push_back(CRule(vRules[i])); } </code> What would be the correct way to delete the object in that vector? Im...

Ah thats just what im after thanks! Shall I just abandon caseless comparisons?

Another quick question, what is the best way to do caseless string comparisons under GCC?

Hmm for some reason I seem to have double posted. ArkM: Believe it or not it was VC++6! lol GCC seems to bring up loads of warnings about things such as comparisons between signed and unsigned int's so on the whole seems a lot strickter (which can only be a good thing) Rgrds

Hi, Thanks for that. Do any of you know where i can look up only standard C++ libraries etc? Thanks

This problem is fixed, basically I ommitted it from the above example but i preceded the class definition with static i.e. static CXMLParser { and that was the cause. For thos of you who may be interested. Rgrds

Hi all, Im having a problem with the stricmp() function. Ive been using it in VC6 and it is recognised, however I am getting this error under GCC. error: `stricmp` undeclared (first use this function) Does this just mean that the stricmp function does not exist in the unix version of the...

Haha no its perfectly fine with the c++ it just doesnt seem to like my use of static. Any thought from someone? Come on guys im desperate and I dont want to revert back to the non-static design as this saves mem because quite a few objects make use of this functionality. Thanks

Hi all, Im having trouble compiling an application which compiles fine under VC6 but not with GCC. The error im getting is: Xml.h:34: error: `static' can only be specified for objects and functions make: *** [main.o] Error 1 The offending piece of code is: class CXMLParser { public: static...

Great, Thanks for that i shall take a look.

Hiya, Im writing an application which is intended for the embedded market and as a result have quite severe memory constraint with which to consider. Does anyone know the best way to monitor the memory usage of the application accurately. Other than looking at the windows task manager which...

Hi guys thanks for the replies. Im busy writing a fuzzy logic based inference engine and needed a way to represent some rules which were recursive in nature as objects within the system. When i say recursive I mean these rules obviously consist of antecedents and consequents. Both of which can...

Hi All, Im trying to write a class which contains itself as a private member, kind of like a recursive class definitions. i.e. class COperator { private: COperator _operator; public: COperator(); ~COperator(); }; Ive tried putting a prototype above it and it doesnt like that. It...

Ah no sorry, i meant data stored in a vb.net data.datatable object. Rgrds

Hi, I would like to perform an equivilent to a group by query on a Data Table object. Is this possible and if so could someone please give me a small demo of how it would be done? Thanks

Thanks a lot, i will try that.

Hi, Thanks for that. I dont suppose you could give me a bit of code to say look at the size of a column in a datatable could you?
