Hi Pavan, I do not understand your code below. I guess there are many ways to get what you want. There is nothing special in converting a string to a date even if the former is stored within a vector which is a mapped value, e.g....
std::map<std::string, std::vector<std::string>> data;
Date d;
if(data.count(myKey)>0)
DateParser::parseISO(data[myKey][index]);
else
...
with myKey a string and index an unsigned int. Hope that helps.

I am able to get around that error.However, what is the best way to convert a string date that is stored in a vector <string> within a map using QuantLib's dateparser class?
Something seems wrong in my function below but I can't figure out what exactly.
void Imp_Vols::Conv_Data_Vols(){
Imp_Vols Test2;/*Test2.total_obs();*/map<string , vector <string> > Input_Vols=Test2.Load_Imp_Vols();
map<string, vector <string> >::iterator iter=Input_Vols.find("EURUSDV1M CMPN Curncy");
while(iter!=Input_Vols.end()){DateParser::parseISO((*iter).second[0]);++iter;
}cout<<"The date of the file is: "<< (*iter).second[0]<<endl;}

Pavan, first you should make sure the the file in question is properly generated. Usually it is located in some subfolder named 'lib'. If it is there, you have to add this folder to the 'linker / additional library directories' property of your project that you want to link against the library.
Happy new year

I made the correction. But the compiler gives me this error:
Error 29 error LNK1104: cannot open file 'QuantLib-vc100-mt-gd.lib'
Here is my corrected version of code:
map<string, vector <string> >::iterator iter=Input_Vols.find("EURUSDV1M CMPN Curncy"); while(iter!=Input_Vols.end()) { DateParser::parseISO((*iter).second[0]); ++iter; }
I am using Visual Studio 2010 to compile.
Two questions:1)is there anything wrong with my code above?2)do i need to change something in my project properties?
thankspavan

Hi Pavan,
try DateParser::parseISO( ) instead. This is a static function defined in the class DateParser.

Hi guys,
just a quick question,
if I have a map such as map<string , vector <string> > Input_Volsand vector <string> has 2 elements. First element is a date in string format and second one is a price.
I am trying to convert each date from string format into a QuantLib date.I am trying to use DateParser.parseISO method from QuantLib to convert all string dates in the map into QuantLib dates.
However, the compiler complains. This is the error.Error 2 error C2275: 'QuantLib::DateParser' : illegal use of this type as an expression
Here is my piece of code.
map<string, vector <string> >::iterator iter=Input_Vols.find("EURUSDV1M CMPN Curncy");
while(iter!=Input_Vols.end()){(*iter).second[0]=DateParser.parseISO((*iter).second[0]);++iter;
}
What am I doing wrong?thankspavan

Peter, Luigi,

Yes, that's what I'm suggesting. Just loop over the lines, and for
each one create the instance and store it in the map. Hundreds is not
that much. Each instance won't weigh more than a few dozens of bytes.
