  • (WinForm/.net) Databind List Of Classes To A DataGridView. But Not Show Certain Public Properties

    - by Pyronaut
    I'm not even sure if i'm doing this correctly. But basically I have a list of objects that are built out of a class. From there, I am binding the list to a datagrid view that is on a Windows Form (C#) From there, it shows all the public properties of the object, in the datagrid view. However there is some properties that i still need accessible from other parts of my application, but aren't really required to be visible in the DataGridView. So is there an attribute or something similar that I can write above the property to exclude it from being shown. P.S. Im binding at runtime. So i cannot edit the columns via the designer. P.P.S. Please no answers of just making public variables (Although if that is the only way, let me know :)).

  • Is there a definitive list of differences between the Ruby on Rails versions?

    - by jedijim
    Is there a list of the differences between the various versions of Rails somewhere on the web? I'm working through an older book about Rails that uses Rails 1.2. I know there are other ways to learn Rails these days, but I thought it would be interesting to try and convert all of the exercises in the book to a more modern versions of Rails (I'm currently working with 2.3.5). A comprehensive list of differences between the various releases would be very helpful. Note that I don't consider the git log a good source of information, as commit messages almost never tell the full story.

  • How do I get a list of all languages that my Windows Forms application has been localized to?

    - by Andrei B
    I have localized localized a Form into two language by setting the Localizable property to True and setting the Language from (Default) to (Dutch(Netherlands)), and I changed the control texts. Visual Studio generated the resource files and compiles them into the application. I need to get a simple list of all the languages that my form has been localized into. Currently it would be just two English and Dutch, but more may come. I need to programatically get a list of "what languages my application is localized into". Do I look into the resource files or use ResourceManager or what? Thanks!

  • Why is MenuItem.AdapterContextMenuInfo null when my list view has a custom adapter?

    - by gregm
    My question: Before I go and use an OnLongClickListener, is there a better way to pass the "what was clicked to create this context menu" information when your list view has a custom adapter? Here are some details: Normally, my code can just do something like this: public boolean onContextItemSelected(MenuItem item) { AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); and then go on and be happy. However, ever since I introduced a custom adapter, item.getMenuInfo() is null. This is a big problem, because my code no longer knows which item was clicked. (My custom Adapter makes each list row a checkbox and a text view) I tried this but failed: Created my own special AdapterContextMenuInfo (called "HasAViewMenuInfo"), but when I pass it in this method, it ends up being null in the menu public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, new HasAViewMenuInfo(v));

  • The return value should be a list but doesn't return as expected?! - Python newbie

    - by user1432941
    Hi this must be a very simple solution that has eluded me this last hour. I've tried to build this test function where the return value of the test_cases list should match the values in the test_case_answers list but for some reason, test case 1 and test case 2 fail. When i print the return values for the test cases they return the correct answers, but for some reason test case 1 and test case 2 return False. Thanks for your help! import math test_cases = [1, 9, -3] test_case_answers = [1, 3, 0] def custom_sqrt(num): for i in range(len(test_cases)): if test_cases[i] >= 0: return math.sqrt(test_cases[i]) else: return 0 for i in range(len(test_cases)): if custom_sqrt(test_cases[i]) != test_case_answers[i]: print "Test Case #", i, "failed!" custom_sqrt(test_cases)

  • Amazon SimpleDB - Is there a way to list all Attributes in a Domain?

    - by beer-drinker
    Hi, I'm using C# and the AWSSDK library form Amazon to test a few things in SimpleDB. All going well so far. However, I am trying to come up with a neat way of retrieving all Attributes that are applicable to a Domain. This is proving to be tricky without having to retrieve an Item, and obviously I can get the list of attributes then. But what if I have 100,000 Items in a Domain. Let's say the first 70,000 Items in a "Person" Domain have: FirstName, LastName, Address And then I hit a Item that has FirstName, LastName, Address, Phone And then I hit another Item around the 80,000 mark which has: FirstName, LastName, Email, Phone In the above example, for the Person Domain, how would I get a list that contains: FirstName, LastName, Address, Email, Phone ...without performing a ridiculous number of select statements? Many thanks!

  • How to list library dependencies of a non-native binary?

    - by lvella
    When developing for native platform, I can use ldd to list all the shared libraries (.so files) a binary executable I build will try to load upon start-up. But when cross-compiling, I don't know how to get the same information. The ldd is not a normal binutils utility, like strip or ar, that can be built alongside gcc for cross compiling, but instead, it is a cryptic shell script that apparently can only run on native platform. So, using the cross-target binutils tools, is there any way to get a list of the dynamically linked dependency for of a foreign binary?

  • sumList predicate needs to check to see if their Sum is equal to the sum of all the elements in the list

    - by nick bonnet
    I am implementing a method that when given Sum and a List. It will check to see that if you add the elements in the list, their sum is equal to the Sum given. Here is what I am trying to do thus far, but I am pretty sure it is wrong... I'm not really sure how to think about it. sumList([],0). sumList([X|Xrest], Sum) :- sumList[Xrest, Sum1), Sum is X + Sum1. Could you give me a point in the right direction or at least let me know how to try to think about the problem?

  • Where does Eclipse save the list of files to open on startup?

    - by Grundlefleck
    Question: where does Eclipse store the list of files it opens on startup? Background: Having installed a plugin into Eclipse which promptly crashed, my Eclipse workspace is in a bit of a state. When started, the building workspace task pauses indefinitely at 20%. Before I uninstall the plugin I want to give it another chance. I have a feeling that the reason Eclipse is pausing is because of a file which was opened when it crashed, which it tries to reopen on startup. If I can stop this file from opening on startup there's a chance I may be able to coax the plugin to behave. The problem is I have no idea where that list of files is persisted between runs of Eclipse. ...a second before I posted this question, I realised I could just delete the file causing the problem (duh). However, the search has frustrated me enough to want to find the answer.

  • How to remove strings of certain lengths

    - by Macosx Iam
    So I have this array, and I want to delete strings that are 2 or 4 characters in length (strings that contain 2 or 4 characters). I am doing this method, and it doesn't work, even though logically, it SHOULD work. public static void main(String[] args) { ArrayList<String> list = new ArrayList<String>(); list.add("This"); list.add("is"); list.add("a"); list.add("test"); for (int i=0; i<list.size(); i++) { if(list.get(i).length()==2 || list.get(i).length()==4) { list.remove(i); } } } I'd like to stick to this method of doing it. Can you please give me some suggestions as to how to correct this code? The output of this code when I run it is: [is, a] Even though I want the output to be [a] because "is" is 2 characters long.

  • How to test processing a list of files within a directory using RSpec?

    - by John Topley
    I'm pretty new to the world of RSpec. I'm writing a RubyGem that processes a list of files within a specified directory and any sub-directories. Specifically, it will use Find.find and append the files to an Array for later output. I'd like to write a spec to test this behaviour but don't really know where to start in terms of faking a directory of files and stubbing Find.find etc. This is what little I have so far: it "should return a list of files within the specified directory" do end Any help much appreciated!

  • Where should I declare a list of 5,000+ words?

    - by user647362
    I am writing a game in python in which I must periodically pull a random word from a list of words. When I prototyped my game I declared a word_list = ['cat','dog','rat','house'] of ten words at the top of one of my modules. I then use choice(word_list) to get a random word. However, I must must change this temporary hack into something more elegant because I need to increase the size of the word list to 5,000+ words. If I do this in my current module it will look ridiculous. Should I put all of these words in a flat txt file, and then read from that file as I need words? If so, how would I best do that? Put each word an a separate line and then read one random line? I'm not sure what the most efficient way is.

  • How do I count list elements that are not hidden?

    - by Baloneysammitch
    Starting with a simple list: <ul> <li>Item 1</li> <li style="display: none;">Item 2</li> <li>Item 3</li> </ul> I know that I can subtract the hidden elements from the list total $('ul li').size() - $('ul li:hidden').size() But I thought there might be a more elegant way to achieve this with jquery: $('ul li:hidden:not').size() That doesn't work. Any ideas?
