Hi, I'm trying to give a newly created instance of a custom picker view controller a reference to another viewController like so (this is inside of a selector from a ponceViewController instance that is called after a tableView row is tapped)... - (IBAction)rowTapped:(id)sender { TimerPickerViewController *viewController = [[TimerPic...
I expected the following code to print "8", "111" and "999". I supposed that each a, b, c and d points to the same memory location. If I change the location through one of them, why would the other not to change? Clearly, my logic is poor, or I overlooked something. It prints "7", "7" and "8", instead. Why? a=b=c=d=7 b = 8 ...
As far as I can tell, there's no reason I shouldn't be allowed to pass a reference to a pointer in C++. However, my attempts to do so are failing, and I have no idea why. This is what I'm doing: void myfunc(string*& val) { // Do stuff to the string pointer } // sometime later { // ... string s; myfunc(&s); // ......
Hey I was just wondering if there is a cool "one liner" that would sort my hash holding array references. So I have a bunch of key/values in my hash something like: $DataBase{$key} = \@value; However I would like to sort the hash by the array[0] element. Then loop through 'em. I had this to begin with: foreach my $key (sort {$DataBa...
I have a situation where Project A refers to Project B which refers to Project C. Project C includes several additional files that are marked as content, copy always. When I build Project B these additional files appear in the output folder for Project B. When I build Project A the dll from Project B appears but not the dll or additional...
I'm referencing a dll (ICSharpCode.SharpZipLib.dll) for my visual studio project from my bin folder, the version I want to use is 0.5.0.0. However, when I run the project, the dll gets replaced with a more recent 0.85.4.369 which is imcompatible with some of the libraries I've got. How do I stop Visual Studio from doing an auto-update ...
In C#, I am developing several Windows Services which have some standard functionality so I have put all this common functionality into a separate referenced utility project. I have a situation where I need to create instances of business classes which reside in my Windows Service project from the utility project using Activator.CreateI...
What is the better way to add a reference to a javascript file from another javascript file? Supose that I have one js file included in my webpage. This javascript has a dependency to another file. So I want to reference the dependency within the original js file, and not from the html code. Is my thought correct? I know I can create a...
Currently our .net code is not processor specific, but it depends on libraries (Oracle/ODP.Net) which are. We've found a solution where we edit the csproj file directly, and put the references in to item groups with a Condition clause based on our selected build configuration. We have 32 bit debug/release and 64bit debug/release, and t...
I have a couple of projects which reference SQL Server assemblies. With SQL Server 2005 and SQL Server 2008 I am currently maintaining 2 project files which point to the same source files and the only difference is the references to the SQL Server assemblies. Is there some way that I can only maintain one project and dynamically specif...
I'm using Visual Studio and COM with C# for the first time and there's something I don't quite understand about the 'references'. How do you know what to reference with a given 'using something.something'? The .Net references seem fairly simple, but COM is less obvious. I'm running Visual Studio 2005 and have the latest VSTO installed, b...
I am learning about C# refs right now. Is it safe to assume that all variables that are assigned with a new are references and not values? Example: SomeType variable = new SomeType() ...
create table Table1(attributeName varchar(100), attributevalue varchar(100), attributeLookupMethod varchar(50)) create table Table2(attributeName varchar(100), CSVAllowableValues varchar(1000) Based on the above 2 tables, using nHibernate, is it possible to only retrieve details from Table2 when Table1.attributeLookupMethod = 'Lookup'?...
Hi everybody! I have a method that creates a new node in a tree - either left or right. If the value is lower than my current value it is inserted on the left, otherwise on the right side. I want to refactor this code, so that I first see on which side I have to insert my element, and then insert it. Before I implemented this twice: On...
We have a Visual Studio 2008 solution under VSS source control. The solution contains many class libraries, many of which need a reference to an assembly that is not part of the solution. Currently we are keeping separate copies of that assembly in each project but as the number of projects grows it gets increasingly tedious to copy in u...

Now that Wolfram Alpha is released, I am interested in finding out if it can be used as a time-saver in daily programming. What would you use Wolfram Alpha to do, that earlier took you more time to do manually? I guess the "Web and Computer systems"-examples is a good start, but there must be more hidden gems that will be really practi...
I have a Visual Studio 2008 Web Site project in a solution with a number of other assembly projects. The Web Site project has 4 types of references: Project, BIN, COM interop, and text files. The Project references autoupdate perfectly. The BIN references for managed DLLs autoupdate with .refresh files, which work well and can be chec...
One of my projects uses Elmah, which references SQLite. Elmah is built against SQLite for .Net version 1.0.44.0 well I was experimenting with some 64 bit stuff (my dev box is 32 bit) so I needed the 64 bit version of SQLite for .Net. I grabbed the latest build of it (1.0.51.0 at the time) and used their installer to install it. For my 3...
I am having a VB application request a list of users from a C DLL: VB will ask the DLL how many users there are, and then initialize an array to the appropriate size. VB will then pass its array by reference to a DLL function, which will fill it with usernames. I started writing the C function like this: foo(char **bar); which would be ...
