• ModX: Selecting and outputting specific menu items using Wayfinder

  - by Staffan Estberg

  tI've been trying to output specific menu items, also wanting to change the names of some, without satisfying results. The problem is that I have three different menu setups throughout the site - the header split into two sections and the footer divided into a couple of columns. This is what I've tried so far - [[Wayfinder? &startId=0 &level=1 &limit=5 &excludeDocs=49,61,55]] While it works excluding all the other links isn's the most optimal solution as there are 11 in total plus I want to be able to 1. rearrange the order and 2. change the names of two of them. Is this possible at all using the Wayfinder or do I have to create a snippet? Thanks in advance.

• Get string value from http response with Mechanize

  - by Gearóid

  Hi, I'm currently integrating facebook into my current app and I've succeeded in retrieving the access_token using the following code: url="#{url}?#{client_id}&#{client_secret}&#{code}&#{redirect_uri}&type=client_cred" agent = Mechanize.new page = agent.get(url) The page object above has a body which contains text something along the lines of access_token=XXXXX I just want to pull out the access_token value. I can get the entire string simply by writing: page.body But I was wondering is there a way to get the access_token value without resorting to regular expressions etc? Thanks.

• Why is a c++ reference considered safer than a pointer?

  - by anand.arumug

  When the c++ compiler generates very similar assembler code for a reference and pointer, why is using references preferred (and considered safer) compared to pointers? I did see Difference between pointer variable and reference variable in C++ which discusses the differences between them. EDIT-1: I was looking at the assembler code generated by g++ for this small program: int main(int argc, char* argv[]) { int a; int &ra = a; int *pa = &a; }

  - by Eatdoku

  Hi, I am trying to understand DbConnection and DbCommand, and the proper way to dispose those objects after use. Following is the code snippet I have. By using "using statement" on DbConnection and DbCommand, would it be sufficient? I am trying to prevent possible memory leak. 2nd question, Do I have to Dispose DbCommand object? thanks a lot DbProviderFactory fac = DbProviderFactories.GetFactory(this.DatabaseProviderName); using (DbConnection dbConn = fac.CreateConnection()) { dbConn.ConnectionString = this.ConnectionString; using (DbCommand comm = fac.CreateCommand()) { comm.CommandText = "select * from aTable"; comm.Connection = dbConn; DataTable targetTable = new DataTable(); DbDataAdapter facDA = fac.CreateDataAdapter(); facDA.SelectCommand = comm; facDA.Fill(targetTable); //assuming Adapter would open / close connection (right assumption?) //do something with the datatable } }

• How can I generate a git diff of what's changed since the last time I pulled?

  - by Teflon Ted

  I'd like to script, preferably in rake, the following actions into a single command: Get the version of my local git repository. Git pull the latest code. Git diff from the version I extracted in step #1 to what is now in my local repository.

• Find out what variable is throwing a NullPointerException programatically

  - by Hectoret

  I know I can find out if a variable is null in Java using these techniques: if (var==null) - too much work try { ... } catch (NullPointerException e) { ...} - it tells me what line is throwing the exception using the debugger - by hand, too slow Consider this line of code: if (this.superSL.items.get(name).getSource().compareTo(VIsualShoppingList.Source_EXTRA)==0) { I would like to know if there's a generic way to find out programatically what variable (not just the line) is throwing the NullPointerException in a certain area of code. In the example, knowing that

• Rotating and Moving a UIImageView (CocoaTouch)

  - by yar

  This code works to rotate: CGAffineTransform transform = CGAffineTransformMakeRotation(radians(lastAngle++)); anImage.transform = transform; and this code works to move my UIImageView CGRect frame = [anImage frame]; frame.origin.x+=1; frame.origin.y+=1; [anImage setFrame:frame]; but when I combine them, the image stretches out increasingly on each run through. Perhaps the frame should not be modified like this?

• Google map - How to escape charaters in the title of a marker in a google map?

  - by Anthony

  Say have this piece of code: var marker = new google.maps.Marker({ position: location, title: 'B&#250;fals', map: map }); This creates a marker as expected but if I hover the mouse over it I don’t see 'Búfals' as I would expect (instead I see the html code). This doesn't make any difference: var marker = new google.maps.Marker({ position: location, title: unescape('B&#250;fals'), map: map }); Any ideas? Thanks.

• How would you write a program to find the shortest pangram in a list of words?

  - by jonathanasdf

  Given a list of words which contains the letters a-z at least once, how would you write a program to find the shortest pangram counted by number of characters (not counting spaces) as a combination of the words? Since I am not sure whether short answers exist, this is not code golf, but rather just a discussion of how you would approach this. However, if you think you can manage to write a short program that would do this, then go ahead, and this might turn into code golf :)

• Adjust Title Helper in Ruby on Rails Tutorial 3.2 to deal with & properly

  - by memoht

  I am using the title helper from the 3.2 edition of the Ruby on Rails Tutorial by Michael Hartl and just realized a snag with the & character showing up in the title as &Amp instead. The relevant snippet of code is here Official Sample App 2nd Edition The problem. I have a School model and am using the School name on the Show view as follows: <% provide(:title, @school.name) %> If my School has a & in the name, it is being replaced with &Amp in the browser title. Ryan Bates Railscasts site has a similiar title helper that solves this issue this way but it is using content_for instead of provide. Trying to adjust the Rails Tutorial helper, but having trouble getting it work properly. Works great expect for this issue.
