excel - Multiply Entire Range By Value? -

-

so best way think of accomplish on large range (about 450k rows) use following sue-do code: 

range("a1").copy ' a1 contains value want multiply column range("mytable[foocolumn]").pastespecial paste:=xlpasteall, operation:=xlmultiply

now works, fact have copy , paste value seems redundant value never going change. 

for each c in range("mytable[mycolumnheader]")     if isnumeric(c) , not c = ""         c.value = c.value * 453.592 ' value in a1 previos sample     end if next

that works, slower. has loop every cell.

i tried: 

with range("mytable[mycolumnheader]")     .value = .value * 453.592 end

but received runtime error type mismatch error if there more 1 value in column.

i thought inserting column , using formular1c1 of "=r-1c * 453.592" .value = .value, shift column , overwrite seemed clunky , think slower paste multiply.

so, have better ways of accomplishing task? 

sub test()      dim rngdata range      set rngdata = thisworkbook.worksheets("sheet1").range("a1:b10")     rngdata = evaluate(rngdata.address & "*2") end sub

kind of outdated looking ?

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.
