• Do sfSubForm.fForm.RecordSource and Forms(fForm).RecordSource refer to the same object and property?

  - by Raymond Rosalind

  Hi, this has me pretty confused and I can't find the answer anywhere else so thought I'd post here to see if anyone can help! I have a form in an Access 2007 database with a subform (sfSubform) embedded in it. The subform control's SourceObject is set to be another form (fForm). fForm's RecordSource starts out as a table. At one point I want to change the data displayed in the subform to the result of a SQL statement, so I use sfSubform.Form.RecordSource = strSQL. This works fine. However, if I ouput the name of the RecordSource for fForm after making this change, it still gives the name of the table that I orginially set. Does sfSubform.Form.RecordSource not change the source of fForm? Is it a copy of fForm that is embedded in the control? Hope all that makes sense.

• Shell Sort problem

  - by user191603

  Show the result of running Shell Sort on the input 9,8,7,6,5,4,3,2,1 using increments { 1,3,7 }. I have done this part. the result is: 9 8 7 6 5 4 3 2 1 (original) 2 1 7 6 5 4 3 9 8 ( 7-sort ) 2 1 4 3 5 7 6 9 8 ( 3-sort ) 1 2 3 4 5 6 7 8 9 ( 1-sort ) Then the question requires me to determine the running time of Shell Sort using Shell's increments of N/2, N/4, ..., 1 for sorted input. I am not quite sure how to answer the second question as I don't understand the requirement of this question. So, would anyone give some hints to let me finish this question? Thank you for your help first!

• How much Java should I have learnt before trying Android programming?

  - by Sidney Yin

  Hi - I have been seeking beginner learning books in Android, and of course found out that I should learn Java first. So I began studying Java and now I am quite comfortable with objects, classes, inheritance, interfaces, and just moved onto Layouts in Swing as well as Swing Features. But I am starting to wonder.... do I know enough about Java now? Can I start programming Android yet? Of course I can keep going in Java, but have been itching to begin programming Android apps. Any definitive answer here about how much Java I need to know before Android? Thanks so much!

• hook to save action in eclipse plugin

  - by 4485670

  I want to create a Google Closure Compiler plugin for eclipse. I already have a popup menu entry to compile a Javascript file to its minified version. But it would be more than helpful if every time you save a *.js that minified version would be generated automatically. I read/heard about natures and builders, extension points and IResourceChangeListener. But I did not manage to figure out what I should use and especially how to get it to work. Is there a working example of a plugin that does "the same kind of thing" so I can work from that or a tutorial to write such? With the answer below I searched for projects that use the IResourceChangeListener and came up with this code: manifest: http://codepaste.net/3yahwe plugin.xml: http://codepaste.net/qek3rw activator: http://codepaste.net/s7xowm DummyStartup: http://codepaste.net/rkub82 MinifiedJavascriptUpdater: http://codepaste.net/koweuh There in the MinifiedJavascriptUpdater.java which holds the code for the IResourceChangeListener the "resourceChanged" function is never reached.

• Twitter URL encoding

  - by Rich

  Hi, We're about to launch a little twitter Christmas competition, and I've run into a little snag. To enter, people will need to post a tweet in the following format: @user blah, blah, blah #hashtag Currently, I have a form where they enter their answer (the blah, blah, blah) and a PHP script which encodes the entire statement and adds on the twitter url: http://www.twitter.com/home?status=%40user%20blah%2Cblah%2Cblah%20%23hashtag Then takes the user to twitter and puts the status in the update field. However, whilst the spaces (%20) are decoded fine the @ and # characters remain as %40 & %23 respectively, even when the tweet is posted. I cannot put the actual characters in the url as twitter mistakes this for a search. Is there any way to solve this? I'd like to do it without requiring username & password etc if possible. Any help will be greatly appreciated.

• What types of conditions can be used for conditional compilation in C++?

  - by user1002288

  This is an exam question for C++: Which of the following statements accurately describe the condition that can be used for conditional compilation in C++? A. The condition can depend on the value of environment variables. B. The condition can depend on the value of any const variables. C. The condition can depend on the value of program variables. D. The condition can use the sizeof() operator to make decision about compiler-dependent operations based on the size of standard data type. E. The condition must evaluate to either a 0 or 1 during preprocessing. I think the answer is E. Is this correct?

• Does beginTransaction in Hibernate allocate a new DB connection?

  - by illscience

  Hi folks - Just wondering if beginning a new transaction in Hibernate actually allocates a connection to the DB? I'm concerned b/c our server begins a new transaction for each request received, even if that request doesn't interact with the DB. We're seeing DB connections as a major bottleneck, so I'm wondering if I should take the time narrow the scope of my transactions. Searched everywhere and haven't been able to find a good answer. The very simple code is here: SessionFactory sessionFactory = (SessionFactory) Context.getContext().getBean("sessionFactory"); sessionFactory.getCurrentSession().beginTransaction(); sessionFactory.getCurrentSession().setFlushMode(FlushMode.AUTO); thanks very much! a

• Social statistics for a given page

  - by Trendee

  I have looked through the API's of facebook and twitter but i cannot seem to find the answer to my question. On websites like http://punchfork.com/recipe/Porkitos-Crispy-Prosciutto-Chips-Nom-Nom-Paleo On the right hand side they have the social stats page with information such as Tweets, Facebook Shares and Stumbleupons. My question is how do they record or gather these results? Is it a case of they have a button that records it in their database then sends you to the page to tweet/share/stumble? But surely that couldn't be accurate as people might not continue to fill out the action.

• Basic iphone timer example

  - by Rob

  Okay, I have searched online and even looked in a couple of books for the answer because I can't understand the apple documentation for the NSTimer. I am trying to implement 2 timers on the same view that each have 3 buttons (START - STOP - RESET). The first timer counts down from 2 minutes and then beeps. The second timer counts up from 00:00 indefinitely. I am assuming that all of the code will be written in the methods behind the 3 different buttons but I am completely lost trying to read the apple documentation. Any help would be greatly appreciated.

• Can SQL Server 2008 Express be used for offering commercial web hosting services?

  - by Tony_Henrich

  I read that SQL Server 2008 Express R2 database size limit has increased to 10G. That's good news. Can I use the Express edition of SQL Server to offer web hosting services to the public? Microsoft should be best in answering this but I can't find a clear answer on their site. I am also seeing several Windows web hosting plans include SQL Server as a total package for less than $5/month. I am wondering how they can afford to offer this.

• convert string array to cell in MATLAB

  - by Maddy

  I need to output a cell to an excel file. Before this I need to convert a date column of integers to datestrings. I know how to do this, but I am not able to put this new string array back into the cell - mycell = { 'AIR' [780] [1] [734472] [0.01] ; ... 'ABC' [780] [1] [734472] [0.02]} I did this -- dates = datestr(cell2mat(mycell(:,4))) ; What I need as an answer is: {'AIR' [780] [1] '14-Dec-2010' [0.01] ; 'ABC' [780] [1] '23-Dec-2010' [0.03] ; } so that I can now send it to an excel file using xlswrite.m

• Number guessing game (3+- guessed result)

  - by Nick Waring

  I've been assigned a task to create a game that generates 4 digits and the user has to guess the digits one at a time to get the correct result. If the number is correct a Y is displayed and if not, a N. This was easy, now the next step was to implement another two responses. If the answer is too high, a H is displayed and too low, an N. Again, was easy - now the third is to use the same design as game 2 but if the number is 3 higher than a H is displayed and same if it's 3 lower than a L is displayed - otherwise an X is displayed. I can't figure out how to do this. Here's my test code for game 2 for just one of the digits - any help is appreciated. (5 was used just for a test.) def guess(): x = 5 g= int(input("Guess the number: ")) if g == x: print("Y") elif g < x: print("L") else: print("H")

• Relative probabilities using random number gen

  - by CyberShot

  If I have relative probabilities of events A, B, C occurring. i.e P(A) = 0.45, P(B) = 0.35, P(C) = 0.20, How do I do represent this using a random number generator between 0 and 1? i.e. R = rand(0,1) if (R < 0.45) event A else if(R < 0.35) event B else if(R < 0.20) event C The above works for two events A,B but I think the above is wrong for three or more since there is overlapping. This is obviously a very simple question and the answer should be immediately evident, but I'm just too stupid to see it.

• Bash, Concatenating 2 strings to reference a 3rd variable

  - by Im Fine

  I have a bash script I am having some issues with concatenating 2 variables to call a 3rd. Here is a simplification of the script, but the syntax is eluding me after reading the docs. server_list_all="server1 server2 server3"; var1 = "server"; var2 = "all"; echo $(($var1_list_$var2)); This is about as close as I get to the right answer, it acknowledges the string and tosses an error on tokenization. syntax error in expression (error token is "server1 server2 server3.... Not really seeing anything in the docs for this, but it should be doable. EDIT: Cleaned up a bit

• iPhone - At user event create objects in the view

  - by insaneshow

  Hello, I am new to iPhone programming, so I think part of the problem is that I don't know what I really want to google to find my answer. I am looking for a method that allows a user to draw a line on the screen. There is no guarantee that it will be straight, it can be curved or whatever. I was thinking that I could create some small square image, and then as they draw, place them into a NSset. But I am not really sure how to communicate each new object up to the view. Up to this point, I've just been messing around with objects I put on the view and then assign movement to those, this is my first jump into on-the-fly object creation. It might be that I just need to jump into a class/object type or even a tutorial, any guidance would be great. Thanks!

• SUM a pair of COUNTs from two tables based on a time variable

  - by Kevin O.

  Been searching for an answer to this for the better part of an hour without much luck. I have two regional tables laid out with the same column names and I can put out a result list for either table based on the following query (swap Table2 for Table1): SELECT Table1.YEAR, FORMAT(COUNT(Table1.id),0) AS Total FROM Table1 WHERE Table1.variable='Y' GROUP BY Table1.YEAR Ideally I'd like to get a result that gives me a total sum of the counts by year, so instead of: | REGION 1 | | REGION 2 | | YEAR | Total | | YEAR | Total | | 2010 | 5 | | 2010 | 1 | | 2009 | 2 | | 2009 | 3 | | | | | 2008 | 4 | I'd have: | MERGED | | YEAR | Total | | 2010 | 6 | | 2009 | 5 | | 2008 | 4 | I've tried a variety of JOINs and other ideas but I think I'm caught up on the SUM and COUNT issue. Any help would be appreciated, thanks!

• android question about service and the method onstartcommand

  - by user516883

  In a service class there is a method to start the service. If that service gets done executing does it runs onstartcommand from the beginning? Is onstartcommand sorta like a loop as long as the service is running. For example i have onstartcommand { int x = 0; if(x == 0){ } else{ } } After that is complete does it run it again. If you know that answer please explain. I have read google explanation of services and it did not explain that part very well. Is onstartcommand sorta like a loop as long as the service is runnning

• Environment.GetFolderPath(...CommonApplicationData) is still returning c:\Docs&Set on Vista

  - by blak3r

  As i understand it, you're supposed to use Environment.GetFolderPath method so you have OS independent code... WinXP uses C:\Docs and Settings\ Vista uses C:\ProgramData and c:\Users I'm using the code below on a vista computer and it's returning a c:\documents and settings directory instead of c:\ProgramData like it should... Any ideas? string commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData); try { File.CreateText( Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\\mycompany\\uid"); log.Debug("Created file successfully"); } catch (Exception ex) { log.Error("Unable to create the uid file: ", ex); } EDIT: I was mistaken... See my answer below. Please vote to close this post as it's no longer relevent.

• Key that yields multiple Results

  - by SgtStud

  I'm pretty new to programming so I'm sorry if this is a stupid question. I was wondering if there was a type of data that returns (possibly) more than one answer per key. For example: TestType<int,String> test = new TestType<int,String>(); So if you typed, test.getKey(1), you could get {"hello","this","is","a","test"}. Basically, is there a type of data that can return multiple answers, sort of like a HashMap and List combined?

  Are there any C/C++ open source audio encoder besides LAME MP3? It doesn't need to be exactly mp3 format, I need a "compressed digital audio file". I do not want to use Lame because it is too big while no programmer can answer a simple question on it (share simple but easily downloadable and readable project containing only needed 2 simple functions... So I'm tired of searching for help with it.. I need something fresh powerful but more readable than this lib I found (mp3stego) ) "I don't want LAME because I am a fighter with its monopoly" Haha..

• Where and why JVM checks that the return type of entry method main(String args[]) is void and not an

  - by akjain

  I will try to answer both, please correct me if I am wrong: Where: If a static method is being called using Classname.method() or using reflection then it doesn’t matter even if you change the return type of the calling method, the same method will still be called. So JVM probably checks this in one of the native methods of jvm.cpp methodHandle m (THREAD, init_klass-find_method(vmSymbols::object_initializer_name(), vmSymbols::void_method_signature())); if (m.is_null()) { ------ THROW_MSG_0 ……….. Why: Although it’s of useless to return a value from main, as java does not do anything with it but if we try to change the return type of main to int for example, JVM throws public static int main(String[] args) { return 1; } java.lang.NoSuchMethodError: main Exception in thread "main" So may be Java mandates the use of same signature for entry method main() to maintain a symmetry in all Java programs written.
