Oh ok. Thanks a lot for all the information.... -
Thanks for the information.
And I have one more related query, if polymorphism works with reference to an object, then can we use like this, vector<Vehicle& >?...Leave a comment:

std::vector of references to derived class objects
Hi All,
Here is the basic example of the using polymorphism. And then my question is below.
...Code:typedef std::vector<Vehicle*> VehicleList; void myCode(VehicleList& v) { for (VehicleList::iterator p = v.begin(); p != v.end(); ++p) { Vehicle& v = **p; // just for shorthand // generic code that works for any vehicle... ... -
how to implement unix "more" type interface
Hi All,
How can I implement the unix "more", in my application.
I would be printing a huge amount of data to the console. While doing so, how can I get the size of the console and accordingly give the more prompt and wait for user input keys to scroll further.
Any ideas??
Thanks

Is this efficient,
...Code:size_t pos = Path.find_last_of("/"); if(pos == Path.length()-1) { Path.erase(Path.length()-1); }Leave a comment:

linking inter dependent libraries
Hi,
what is the order of the libraries in the Makefile, for linking inter dependent libraries. i'm getting linker error for the following scenario.
I have lib1.a and lib2.a, with which lib1.a needs lib2.a and lib2.a needs lib1.a for linking. How can this be resolved.
any thoughts on this would be helpful.
thanks

It got fixed when I used it as,
xmlMessage.appe nd(xmlobj.GetRe sponseMsg().c_s tr());
instead of
xmlMessage.appe nd(xmlobj.GetRe sponseMsg());
How there could be a different behaviour when using a "string" or a "const char*" for the string api's.
thanks

std::string append problem
Hi,
I have a strange problem with strings concatenation. I have a xmlobj, which contains request, response, status, notification and control which are all of type std::string.
When I dump that, it prints every member variable properly. But when I concatenate as below, "response" string alone is not appended. though the data is there.
Please help me to fix this problem
Thanks

convert std::string to enum
Hi,
Converting enum to strings is simple. Just we can use the enum as the i ndex to get the string from an array of strings.
But how do I convert string to enum. Should I need to compare with every string in the array and return the enum when it matches.
Whats the efficient way to do this?
Thanks

That's the way I'm doing it for putting the data into this.
But I would like to read the data back from it to build the string buffer table (tabular format).
Thanks...Leave a comment:

It's not like that. For a single id, there could be multiple sets of names and values. here for id=100, {name = c1, value = r1}, {name = c2, value = r1}.
so it goes like that....
id c1 c2
------------
100 r1 r1
200 r2 r2
Any idea how can i build this..
