c# - The name 'Properties' does not exist in the current context , with app.config -


i use in project save string connection in app.config :

 <?xml version="1.0" encoding="utf-8" ?>  <configuration> <configsections>     <sectiongroup name="usersettings" type="system.configuration.usersettingsgroup,  system, version=4.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089" >         <section name="contatroco.properties.settings"  type="system.configuration.clientsettingssection, system, version=4.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089" allowexedefinition="machinetolocaluser" requirepermission="false" />     </sectiongroup> </configsections> <usersettings>     <contatroco.properties.settings>         <setting name="servidor" serializeas="string">             <value />         </setting>         <setting name="banco" serializeas="string">             <value />         </setting>         <setting name="usuario" serializeas="string">             <value />         </setting>         <setting name="senha" serializeas="string">             <value />         </setting>     </contatroco.properties.settings> </usersettings>

and in code of c# use this

        servidor = combobox1.selectedvalue.tostring();         usuario = txtusuario.text;         password = txtpassword.text;         catalog = cmbbancos.text;           properties.settings.default.servidor = servidor;         properties.settings.default.banco = catalog;         properties.settings.default.usuario = usuario;         properties.settings.default.senha = password;         properties.settings.default.save();

these codes works perfects in 1 project , when import form other projetco ( add existing item , rename namespace ) have error on part "the name 'properties' not exist in current context", have add system.configuration reference project error con tinues. help.

if don't have app.config in imported project, might result in error. inorder have common config files, place these files in seperate folder, sharedconfigs , add shortcut file in required projects. check this out.

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
