I cannot however access the value of the private member 'version' this way (or any other private member).. i had assumed that v...

I am using a DataView of same DataTable which loads the Master to load the Detail GridView, by filtering what I need to show in the DetailGridView.

It's a crazy question because it seems simple. I cannot find anywhere that blatantly states the answer. If I type: void doThis(){ System.out.println("Hello Stackoverflow."); } what is the default scope of doThis()? Public? Protected? Private? Thanks in advance. ...

Private Function FindThing(ByVal Things As List(Of Thing)) As Thing Dim ReverseOrderThings As List(Of Thing) = Things ReverseOrderThings.Reverse() For Each t As Thing In R...
Let's say I have a stored procedure with this in its body: EXEC 'INSERT INTO ' + quotename(@table) ' blah...' SELECT IDENT_CURRENT('' + @table + '') Is IDENT_CURRENT() guaranteed to get the identity of that row INSERTed in the EXEC? IDENT_CURRENT() "returns the last identity value generated for a specific table in any session and any ...
I'm writing a very simple mailing system for a Rails app. I'm using RESTful authentication. It's a fairly conventional setup, where I'm sending the same email when a user signs up and when a user forgets their password. I'm just having one problem that I can't seem to wrap my head around. I'd like to use the same email template for both...
I'm creating a site on which there are many page components that refer to objects that are used elsewhere in the page. Some of these components are used in other pages as well, thus my desire to use includes rather than cut-and-paste. The problem is that if I have identical "jsp:useBean" statements in multiple components of the page,...

So let's say, for example: user has_many :posts post belongs_to :user Anywhere in the users resource I can access the user variables as I would expect. @user.name, @user.email, @user.login, etc. a...
Is there any way to keep global variables visible only from inside a library while inaccessible from programs that access that library in C? It's not that it is vital to keep the variable protected, but I would rather it if programs couldn't import it as it is nothing of their business. I don't care about solutions involving macros. ...
We have a product that has both a winforms and a web client, and are providing the users a way to launch into another company asset (a web application). We need to make sure that the user only ever has one instance of the other web application open in a browser (or at least that we've opened for them). We accomplished this (sort of) by d...
