runtime

I have a simple class Apple extends from another simple class Fruit. At run-time, I could use Fruit fruit = new Apple(); fruit.getClass(); to get the actual type of fruit object, which is Apple.class. I could also use fruit instanceof Apple , and fruit instanceof Fruit to verify if this fruit object is an instance of Apple or Fruit. Both of these 2 expressions return true, which is normal. But is there a way to determine precisely the declared type of fruit identifier? Which in this case is Fruit . You're actually asking a question about the variable declaration of fruit rather than the actual

My question is concerning the runtime error 91 in VBA for excel. I've done some searching to no avail. My code is below. I have noted the section causing the error. Why is this happening, and how can i fix it and move on? Sub RemoveFooterRows(theFile) Dim found As Range Dim aggregateRow ''Error is from section below found = isItRow = Workbooks(theFile).Worksheets(1).Columns(1).Find _ ("Summary", Range("A1"), xlValues, xlPart, xlByRows, xlNext, False, , False) ''Error is from section above MsgBox ("val is " & found.Row) End Sub Sub RemoveFooterRows(theFile) Dim found As Range Set found =

How would you instantiate a generic at runtime instead of at compile time. Example without using new. You cannot do this without use of new . You can do it in any declarative section, however that generic will only be extant for the duration of the scope of that declaritive section. for example (not compiled ada-like pseudocode): get(length) declare package stack is new stack_generic (max_stack_size => length); begin stack.push(); ... end; -- stack package no longer in scope. Does this help ? 来源： https://stackoverflow.com/questions/9630086/ada-generics-at-run-time

I want to count the number of members in a structure. For example: typedef struct { char MrChar; int MrInt; long MrLong; } Bg_Typedef; Bg_Typedef FooStr; I create a function prototype that should return number of members in the structure int NumberOfMem(Bg_Typedef *psStructure); => NumberOfMem(&FooStr) should return 3 There is no way to do this that is inbuilt into the C language AFAIK. If you want to do this you would need to remember the number of members or hard code the number as return value of your function. C can tell you the size in bytes of your structs but not the number of members

i have code for call action and i need best way to declare run time permission ive tried many codes but i always get error here is my basic code any suggestion for make it work with runtime permission thanks in advance public class MainActivity extends Activity { private Button button; private EditText etPhoneno; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); button = (Button) findViewById(R.id.buttonCall); etPhoneno = (EditText) findViewById(R.id.editText1); // add button listener button.setOnClickListener(new View
