java - Sending Email with attachment, sends a blank file -

-

i using code: 

file mydir = new file(getapplicationcontext().getfilesdir().getabsolutepath()); try {                     log.i("csv testing ", "csv file creating");     filewriter fw = new filewriter(mydir + "/myfile.csv");     //                  // write data file                  //        log.i("csv testing ", "csv file created , data has been saved");     // process sending email csv file     file csvfile = new file(mydir,"myfile.csv");     // , sending email attachment } catch (ioexception e) {     log.i("exportcsv exception", e.tostring()); }

but sends myfile.csv blank file. checked file explorer, myfile.csv not blank , contains right data. how can solve this?

my logcat messages 

i/csv testing (16920): csv file creating i/csv testing (16920): csv file created , data has been saved i/csv file(16920): csv file exists i/send email testing(16920): email sending d/dalvikvm(16920): gc freed 2902 objects / 186576 bytes in 156ms i/activitymanager(   60): starting activity: intent { act=android.intent.action.chooser cmp=android/com.android.internal.app.chooseractivity (has extras) } w/activitymanager(   60): startactivity called non-activity context; forcing intent.flag_activity_new_task for: intent { act=android.intent.action.chooser flg=0x800000 cmp=android/com.android.internal.app.chooseractivity (has extras) } i/activitymanager(   60): displayed activity com.android.email/.activity.messagecompose: 1156 ms (total 2117 ms) w/inputmanagerservice(   60): starting input on non-focused client com.android.internal.view.iinputmethodclient$stub$proxy@43cf3050 (uid=10023 pid=207) w/iinputconnectionwrapper(  207): showstatusicon on inactive inputconnection

if case....

ur path 2 file must missing somewhere, means path 2 file must incorrect....

and bcoz of this....

the statement file csvfile = new file(mydir,"myfile.csv");must creating new empty file on location..

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
