sql - Converting mysqlpp::String to C++ int -

-

ok, i'm relatively new using mysqlpp library used in visual studio connect mysql database , having trouble trying convert vector of type mysqlpp::string vector of type int. have experience mysqlpp , mind helping me out little? i've posted example of i'm trying below appears in code. assume vector futureitemsets populated , want copy on contents integer vector. can provide!

vector<int> timeframeitemsets; vector<mysqlpp::string> futureitemsets;  for(int j = 0; j < static_cast<int>(futureitemsets.size()); j++) { timeframeitemsets.push_back(futureitemsets[j]); }

mysqlpp::string has operator int() code snippet should work. problem having it?

if want more explicit, can use mysqlpp::string's conv function:

int = futureitemsets[j].conv<int>(0); timeframeitemsets.push_back(i);

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
