i have word search creator app. user inputs list of words, width , height settings, word placement settings etc. when user clicks save button, these settings saved file, later user can open app saved settings. have no idea how though. (except opening savefiledialog) the savefiledialog provides application gui save window allows user choose save location , filename. dialog comes event handler (which believe called fileok) can access mysavefiledialog.filename . no data or file has been saved yet. that, take variety of routes, simplest using system.io.streamwriter: using system.io; ... streamwriter sw = new streamwriter(mysavefiledialog.filename); //pass chosen filename sw.writeline( string goes here ); sw.close(); you'll have come string representation of data, though. for more complex types, use xml serialization. can define data structure class , use .net's built in system.xml.serialization namespace automatically output representation of class easy re...

i want use pdo in application. confused regarding use of pdo here. because application access target multiple users. lets 100 users in simultaneously . so, read pdo create 100 db connections access. can create problem limit on concurrent connections allowed server. , new users connection error. how can use pdo such way handles concurrent connections , not overhead? 100 concurrent users not impressive number though. taken average user makes click once minute, have 100 connects 60 seconds, makes 1.5 connects / second. sanely written app should perform no longer 0,1 sec. means 10 connections fit in 1 second. , have 1.5. yes, can peak sometimes, anyway, number of allowed connections last thing think of. database killed far earlier limit reached - due improper indexing , architecture.

is ok use this keyword in final instance variable declaration/initialization in java? like this: private final someclass foo = new someclass(this); it worked when tried out. , since not static variable guess should referring particular instance. felt unsure if advisable or not therefore wanted ask here. edit: main class android activity class, , someclass-instance needs activity context. it "technically valid" this. indeed, this refers particular instance - namely, instance contains instance of someclass . but not recommend in general. exact behavior , state of this passed constructor depends on subtle details. consider following example: class someclass { public someclass(dangerousselfreference dangerousselfreference) { system.out.println("state: "); system.out.println(" a: "+dangerousselfreference.geta()); system.out.println(" b: "+dangerousselfreference.getb()); system....
