  • Return value changed after finally

    - by Nestor
    I have the following code: public bool ProcessData(String data) { try { result= CheckData(data); if (TextUtils.isEmpty(result)) { summary="Data is invalid"; return false; } ... finally { Period period = new Period(startTime, new LocalDateTime()); String duration = String.format("Duration: %s:%s", period.getMinutes(), period.getSeconds()); LogCat(duration); } return true; As I learned from this question, the finally block is executed after the return statement. So I modified my code according to that, and in the finally I inserted code that does not modify the output. Strangely, the code OUTSIDE the finally block does. My method always returns true. As suggested, it is not a good idea to have 2 return. What should I do?

  • How to add default value on save form?

    - by Ignacio
    I have an object Task and a form that saves it. I want to automatically asign created_by field to the currently logged in user. So, my view is this: def new_task(request, task_id=None): message = None if task_id is not None: task = Task.objects.get(pk=task_id) message = 'TaskOK' submit = 'Update' else: task = Task(created_by = GPUser(user=request.user)) submit = 'Create' if request.method == 'POST': # If the form has been submitted... form = TaskForm(request.POST, instance=task) if form.is_valid(): task = form.save(commit=False); task.created_by = GPUser(user=request.user) task.save() if message == None: message = 'taskOK' return tasks(request, message) else: form = TaskForm(instance=task) return custom_render('user/new_task.html', {'form': form, 'submit': submit, 'task_id':task.id}, request) The problem is, you guessed, the created_by field doesn't get saved. Any ideas? Thanks

  • Using the value of a variable as another variables name in Ruby

    - by hrickards
    Hi, I'm just starting out in learning Ruby and I've written a program that generates some numbers and assigns them to variables @one, @two, @three etc. The user can then specify a variable to change by inputting it's name (e.g one). I then need to do something like '@[valueofinout] = asd'. How would I do this, and is there a better way as the way I'm thinking of seems to be discouraged? I've found x = "myvar" myvar = "hi" eval(x) -> "hi" but I don't completely understand why the second line is needed. In my case would I use something like @one = "21" input = "one" input = "@" + input changeto = "22" eval(input) -> changeto Thanks

  • VBA Tab Key putting actual Tab Value in Text Box instead of navigating to next control

    - by ray023
    I have a VBA form (in Excel if that matters) that contains text boxes. On three occasions, I have found myself pressing the tab key to navigate to the next control, but instead an actual TAB is being put in the text box. The form normally acts as it should, but it does concern me that this gremlin is showing up sporadically. It has shown up on Office 2003 as well as Office 2007 on two different computers. Has anyone else encountered this problem and, if so, how did you fix it?

  • Creating one row of information in excel using a unique value

    - by user1426513
    This is my first post. I am currently working on a project at work which requires that I work with several different worksheets in order to create one mail master worksheet, as it were, in order to do a mail merge. The worksheet contains information regarding different purchases, and each purchaser is identified with their own ID number. Below is an example of what my spreadsheet looks like now (however I do have more columns): ID Salutation Address ID Name Donation ID Name Tickets 9 Mr. John Doe 123 12 Ms. Jane Smith 100.00 12 Ms.Jane Smith 300.00 12 Ms. Jane Smith 456 22 Mr. Mike Man 500.00 84 Ms. Jo Smith 300.00 What I would like to do is somehow sort my data so that everythign with the same unique identifier (ID) lines up on the same row. For example ID 12 Jane Smith - all the information for her will show up under her name matched by her ID number, and ID 22 will match up with 22 etc... When I merged all of my spreadsheets together, I sorted them all by ID number, however my problem is, not everyone who made a donation bought a ticket or some people just bought tickets and nothing us, so sorting doesn't work. Hopefully this makes sense. Thanks in advance.

  • How can I check if a value exists in a list using C#

    - by Samantha J
    I have the following code that gives me a list of id and names from the new ASP.NET MVC5 Identity: var identityStore = new IdentityStore(); var users = ( from user in identityStore.DbContext.Set<User>() select new { id = user.Id, name = user.UserName } ); How could I modify this so that it allows me to check if a UserName exists? Here's the user class: public class User : IUser { public User(); public User(string userName); [Key] public string Id { get; set; } public virtual ICollection<UserLogin> Logins { get; set; } public virtual UserManagement Management { get; set; } public virtual ICollection<UserRole> Roles { get; set; } public string UserName { get; set; } }

  • Lua: Why changing value on one variable changes value on an other one too?

    - by user474563
    I think that running this code you will get excactly what I mean. I want to register 5 names to a register(people). I loop 5 times and in each loop I have a variable newPerson which is supposed to save all information about a person and then be added to the people register. In this example only the names of the people are being registered for simplicity. The problem is that in the end all people turn to have the same name: "Petra". I playied a bit with this but can't get a reasonable reason for this behaviour. Help appreciated! local people={} local person={ name="Johan", lastName="Seferidis", class="B" } local names={"Markus", "Eva", "Nikol", "Adam", "Petra"} --people to register for i=1, 5 do --register 5 people local newPerson=person local name=names[i] for field=1, 3 do --for each field(name, lastname, class) if field==1 then newPerson["name"]=name end --register name end people[i]=newPerson end print("First person name: " ..people[1]["name"]) print("Second person name: "..people[2]["name"]) print("Third person name: " ..people[3]["name"])

  • Change cell color in Excel according to adjacent dropdown value

    - by Andrew Heath
    I understand how to make a dropdown list. I understand how to make conditional formatting change the color of a cell. What I do not understand is how to make conditional formatting change the color of a cell based solely on the state of another cell (not a comparison). A1 is a No / Yes dropdown list B1 is a criteria statement If the user satisfies the criteria statement in B1, they select Yes on the dropdown list in A1. For quick reference, if possible, I'd like B1 to change to a green background color on this event... and of course change back to no-fill if the dropdown is reset to No. Is this possible in Excel 2003 and/or 2007?

  • Opengl: fit a quad to screen, given the value of Z.

    - by hytparadisee
    Short Version of the question: I will put a quad. I know the width and height of the screen in window coordinates, i know the Z-coordinates of the quad in 3D. I know the FOVY, I know the aspect. The quad will be put along Z-axis, My camera doesn't move (placed at 0, 0, 0). I want to find out the width and height of the quad IN 3D COORDINATES that will fit exactly onto my screen. Long Version of the question: I would like to put a quad along the Z-axis at the specified offset Z, I would like to find out the width and height of the quad that will exactly fill the entire screen. I used to have a post on gamedev.net that uses a formula similar to the following: *dist = Z * tan ( FOV / 2 )* Now I can never find the post! Though it's similar, it is still different, because I remembered in that working formula, they do make use of screenWidth and screenHeight, which are the width and height of the screen in window coordinates. I am not really familiar with concepts like frustum, fov and aspect so that's why I can't work out the formula on my own. Besides, I am sure I don't need gluUnproject (I tried it, but the results are way off). It's not some gl calls, it's just a math formula that can find out the width and height in 3D space that can fill the entire screen, IF Z offset, width in window coordinates, and height in window coordinates, are known. Thanks all in advance.

  • Database table relationships: Always also relate to specified value (Linq to SQL in .NET Framework)

    - by sinni800
    I really can not describe my question better in the title. If anyone has suggestions: Please tell! I use the Linq to SQL framework in .NET. I ran into something which could be easily solved if the framework supported this, it would be a lot of extra coding otherwise: I have a n to n relation with a helper table in between. Those tables are: Items, places and the connection table which relates items to places and the other way. One item can be found in many places, so can one place have many items. Now of course there will be many items which will be in ALL places. Now there is a problem: Places can always be added. So I need a place-ID which encompasses ALL places, always. Like maybe a place-id "0". If the helper table has a row with the place-id of zero, this should be visible in all places. In SQL this would be a simple "Where [...] or place-id = 0", but how do I do this in Linq relations? Also, for a little side question: How could I manage "all but this place" kind of exclusions?

  • Getting value of "System.Windows.Controls.TextBlock" when binding to Silverlight ComboBox

    - by sipwiz
    I'm attempting to use a Silverlight ComboBox with a static list of elements in a very simple binding scenario. The problem is the selected item is not returning me the Text of the TextBlock within the ComboBox and is instead returning "System.Windows.Controls.TextBlock". My XAML is: <ComboBox SelectedValue="{Binding Country, Mode=TwoWay, NotifyOnValidationError=True, ValidatesOnExceptions=True}"> <TextBlock FontSize="11" Text="Afghanistan" /> <TextBlock FontSize="11" Text="Albania" /> <TextBlock FontSize="11" Text="Algeria" /> </ComboBox> In my C# file I'm binding to the ComboBox using: Customer customer = new Customer() { Country = "Albania" }; DataContext = customer; The binding does not result in Albania as the selected country and updating the ComboBox choice results in the Country being set to "System.Windows.Controls.TextBlock". I've tried fiddling around with DisplayMemberPath and SelectedValuePath but haven't found the answer. I suspect it's something really simple I'm missing.

  • map<string, vector<string>> reassignment of vector value

    - by user2950936
    I am trying to write a program that takes lines from an input file, sorts the lines into 'signatures' for the purpose of combining all words that are anagrams of each other. I have to use a map, storing the 'signatures' as the keys and storing all words that match those signatures into a vector of strings. Afterwards I must print all words that are anagrams of each other on the same line. Here is what I have so far: #include <iostream> #include <string> #include <algorithm> #include <map> #include <fstream> using namespace std; string signature(const string&); void printMap(const map<string, vector<string>>&); int main(){ string w1,sig1; vector<string> data; map<string, vector<string>> anagrams; map<string, vector<string>>::iterator it; ifstream myfile; myfile.open("words.txt"); while(getline(myfile, w1)) { sig1=signature(w1); anagrams[sig1]=data.push_back(w1); //to my understanding this should always work, } //either by inserting a new element/key or //by pushing back the new word into the vector<string> data //variable at index sig1, being told that the assignment operator //cannot be used in this way with these data types myfile.close(); printMap(anagrams); return 0; } string signature(const string& w) { string sig; sig=sort(w.begin(), w.end()); return sig; } void printMap(const map& m) { for(string s : m) { for(int i=0;i<m->second.size();i++) cout << m->second.at(); cout << endl; } } The first explanation is working, didn't know it was that simple! However now my print function is giving me: prob2.cc: In function âvoid printMap(const std::map<std::basic_string<char>, std::vector<std::basic_string<char> > >&)â: prob2.cc:43:36: error: cannot bind âstd::basic_ostream<char>::__ostream_type {aka std::basic_ostream<char>}â lvalue to âstd::basic_ostream<char>&&â In file included from /opt/centos/devtoolset-1.1/root/usr/lib/gcc/x86_64-redhat-linux/4.7.2/../../../../include/c++/4.7.2/iostream:40:0, Tried many variations and they always complain about binding void printMap(const map<string, vector<string>> &mymap) { for(auto &c : mymap) cout << c.first << endl << c.second << endl; }
