Can we get PowerBuilder Pb Data window object using hooking -

-

i testing powerbuilder application using iaccessible object. not able newly added row pbdatawindow object. possible pbdatawindow object using hooking. can not modify application code , don't have there source code also.

regards, rajendar

you can access datawindow control accessibility properties using iaccessible need set in code (ide) or in run-time. suspect case windows application uses accessibility unless language sets default accessibility properties when aren't explicitly provided.

if don't have access source code forced @ microsoft windows 'window class names' handle objects challenging not mention name of object might not consistent across various instances of application in memory.

for looking use accessibility , have access source code, how set. can set these many different object types , columns within datawindow object.

assumption: datawindow control named, "dw_invoice".

setting accessible properties dynamically @ runtime

dw_invoice.accessiblename = 'invoicedatawindow" dw_invoice.accessibledescription = "the current invoice" dw_invoice.accessiblerole = defaultrole!

setting accessible properties in development ide

  1. select datawindow control
  2. highlight "other" tab
  3. enter accessiblename
  4. enter accessibledescription
  5. choose accessiblerole (see pb enumerated list of roles)

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.
