c# - Saving plain text to RichText -

-

i'm little confused following code. i'm taking plain text stored in database , supplying text portion of richtextbox control saving file.

the first file blank though contain data.

richtextbox test = new richtextbox(); for(int = 0; < dt.rows.count; i++) {      test.text = dt.rows[i][1].tostring();      string file_name = path.combine(path, dt.rows[i][0].tostring() + ".rtf");      test.savefile(file_name, richtextboxstreamtype.richtext);      test.clear(); }

now work around though it's ugly did following , write first entry file correctly

bool run_once = true; richtextbox test = new richtextbox(); for(int = 0; < dt.rows.count; i++) {      test.text = dt.rows[i][1].tostring();      string file_name = path.combine(path, dt.rows[i][0].tostring() + ".rtf");      test.savefile(file_name, richtextboxstreamtype.richtext);      test.clear();       if (run_once)      {           file.delete(file_name);           run_once = false;           i--;      } }

could shed light here?

interesting. "think" might bug. work-around:

using (richtextbox test = new richtextbox()) {   (int = 0; < dt.rows.count; i++) {     test.selectall();     test.text = dt.rows[i][1].tostring();     string file_name = path.combine(path, dt.rows[i][0].tostring() + ".rtf");     test.savefile(file_name, richtextboxstreamtype.richtext);     test.clear();   } }

the selectall() needed make bug go away. not sure why.

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.
