internet explorer - Using Selenium IE driver in C# to quickly post a large amount of text (10,000 lines) -

-

so i'm writing script automate simple, monotonous task using selenium internet explorer driver in c#.

everything works great, tad bit slow @ 1 point in script , i'm wondering if there quicker way available want.

the point in question when have fill out textbox lot of information. textbox filled 10,000 lines each line never exceeds 20 characters.

however, following approach slow...

// process sample file using linq query var items = file.readalllines(samplefile).select(a => a.split(',').first());  // process items want add textbox var stringbuilder = new stringbuilder(); foreach (var item in items) {      stringbuilder.append(item + environment.newline); }  inputtextbox.sendkeys(stringbuilder.tostring());

is there set value of textbox want? or bottleneck?

thank time , patience!

so suggested richard - ended using ijavascriptexecutor.

the exact solution replace call sendkeys in following line of code: 

inputtextbox.sendkeys(stringbuilder.tostring());

with line of code:

((ijavascriptexecutor)iedriver).executescript("arguments[0].value = arguments[1]",                                           inputtextbox, stringbuilder.tostring());

casting internetexplorerdriver object ijavascriptexecutor interface in order reach explicitly implemented interface member executescript , making call member arguments above did trick.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
