Question No: 6    ( Marks: 5 )

We have an application in which there is a function named “TestingFunction”. There are 2 local
integer variables declared in it. One is named “simpleVariable” and other is named
“staticVariable”. The storage class of “staticVariable” is static. Suppose this function is called and
when it returns the value of “simpleVariable” is lost but that of “staticVariable” is preserved. Why
is it so?
  
Question No: 7    ( Marks: 5 )

Suppose we have called TranslateMessage function before calling DispatchMessage to handle
messages. Write down the message sequence sent to the windows procedure when Shift+S keys are
pressed.
  
Question No: 8    ( Marks: 5 )

Suppose an application has a window and 2 menu resources, one is IDM_MENU1 and second is
IDM_MENU2. While registering the window class in this application, we make IDM_MENU1 the
class menu. Now, we have 2 scenarios:
1.  We give the menu handle of IDM_MENU2 during creating the window.
2.  We give NULL as the menu during creating the window.
You have to tell which menu will be associated to the window in both cases.   
Question No: 9    ( Marks: 5 )

We have 128MB RAM in our system. Suppose we run a Win32 application that declares an array
of 800MB whose each element is of 512KB. How will operating system handle the situation when
the application requests 10 elements of that array?
  
Question No: 10    ( Marks: 5 )

Suppose we have 2 menu items named “Show” and “Clear”. Their identifiers are ID_FILE_SHOW
and ID_FILE_CLEAR respectively. Write down the resource statements to add accelerators for
these menu items.
  
Question No: 11    ( Marks: 10 )

Write WinMain and window procedure of an application that creates an overlapped window with 2
buttons. One button has text “Width” printed on it and when it is clicked it displays the width of
window’s client area through message box while the other button has text “Height” printed on it
and when clicked displays the height of window’s client area through message box.
Note: To convert a long value into string, simply use LongToString function.
e.g. If “ClientHeight” is a long variable and “strClientHeight” is a string variable then to
convert the value of “ClientHeight” to string and store it in “strClientHeight” proceed as
follows:
  LongToString(ClientHeight);
  (This function will not run on Visual C++ or Dev C++ compilers)
  
Question No: 12    ( Marks: 5 )

An application whose primary thread’s entry point is WinMain creates another thread using
CreateThread function. Security Attribute parameter is set to NULL, stack size is 512KB and
thread function is MyFunction. What would be the entry point and exit point of this secondary
thread?
