Say I create a char array, and I assume the char array is empty. If I check the value of the first element in the array ( arr[0] ), what would be the result of this expression? It depends on where and how the array is declared. If the array is declared at file scope (outside of any function), or is declared static , and does not have an explicit initializer, then the contents of the array will be initialized to 0. If the array is declared at block scope (within a function or block) and is not declared static , and does not have an explicit initializer, then the contents of the array are

Say you have a class declaration, e.g.: class MyClass { int myInt=7; int myOtherInt; } Now, is there a way in generic code, using reflection (or any other means, for that matter), that I can deduce that myInt has a default value assigned, whereas myOtherInt does not? Note the difference between being initialised with an explicit default value, and being left to it's implicit default value (myOtherInt will be initialised to 0, by default). From my own research it looks like there is no way to do this - but I thought I'd ask here before giving up. [Edit] Even with nullable and reference types I

I have an Oracle database, and a table with several not null columns, all with default values. I would like to use one insert statement for any data I want to insert, and don't bother to check if the values inserted are nulls or not. Is there any way to fall back to default column value when null is inserted? I have this code: <?php if (!empty($values['not_null_column_with_default_value'])) { $insert = " INSERT INTO schema.my_table ( pk_column, other_column, not_null_column_with_default_value) VALUES (:pk_column,:other_column,:not_null_column_with_default_value) "; } else { $insert = " INSERT

Firefox has come to believe that my default spell check language should be Spanish. My global preferences have English selected: Preferences->Content->Languages->English [en] and on a page-by-page basis I'm able to reset the spell checker language via: Right click->Languages->English (United States) However, for newly opened pages or new sessions the default spell check language returns to Spanish. I found a workaround here: https://support.mozilla.org/en-US/questions/975459#answer-494574 Which suggested that installing a new dictionary would change the default. However, this issue has bugged

I would to change the menuitems in the default context menu provided in the Web Browser Control. I have already tried: webbrowser.contextmenu = mycontextmenu. Nothing changed. Is there a way to do this? Answer - YES. There is a setting in the webbrowser control for: .IsWebBrowserContextMenuEnabled = false; Setting this to false disables the IE contextmenu, allowing whichever one you set to rule the roots. Simples.. The short answer is yes. See this article on codeproject . Here is another (shorter) article on codeproject The short answer is no. See this thread for more details. I'm trying to

I seem to have a problem with my code. I have created a test activity, just to see what's wrong, still I can't. public class test extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); String extra = "test"; NotificationManager myNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); Intent intent = new Intent(this, test.class); Notification notification = new Notification(R.drawable.icon, extra, System.currentTimeMillis());
