flat file - SSIS Convert Blank or other values to Zeros -

-

after applying unpivot procedure, have amount column has blanks , other characters ( "-"). convert non-numberic values zero. use replace procedure converts 1 @ time. also, tried use following script

/**

public overrides sub input()_processinputrows(byval row input()buffer)      if row.columnname_isnull = false or row.columnname = ""             dim pattern string = string.empty            dim r regex = nothing            pattern = "[^0-9]"            r = new regex(pattern, regexoptions.compiled)            row.columnname = regex.replace(row.columnname, pattern, "")        end if end sub

**/

but i'm getting error.i don't script maybe placed in wrong place. bottom line need convert non-numberic values.

thank in advance help.

i @ regular expressions great way introduce problem existing one.

what did simulate problem write select statement added 5 rows. 2 valid numbers, rest empty string, string spaces , 1 hyphen.

enter image description here

i wired script component , set column read/write

enter image description here

the script used follows. verified there value there , if so, attempted convert value integer. if failed, assigned zero. vb not strong suit if have been done more elegantly, please edit script.

public overrides sub input0_processinputrow(byval row input0buffer)     ' ensure have data work     if not row.columnname_isnull         ' test whether it's number or not         ' trycast doesn't work value types i'm going lazy route         try             ' cast integer , string because              ' vb weak             row.columnname = cstr(ctype(row.columnname, integer))         catch ex exception             row.columnname = 0         end try      end if  end sub

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.
