• How to create your own advert engine for an Android App?

  - by Richard Green

  I have an Android App and I would like to start putting non-intrusive advert into the app. However, I have the benefit of knowing exactly what products I would like to put in these adverts (which will basically be amazon "similar products" type things and a few other suppliers). Is there any ad-engine out there that will allow me to do this? The ones I see already just put what they think are suitable. I have scoured and I can't find an example of this... Any ideas? Should I just bite the bullet and write my own classes to do this ?

• 2 table SQL Query weird results

  - by javArc

  Ok this is driving me nuts, I need to write an SQL query that will grab product information from 2 tables. The first table 'products' contains the productId, productname, quantityperunit and unitprice. Now I can search by productname and categoryname individually, but when I try to combine the 2 I get crazy results, Here's the query: "SELECT DISTINCT productId, productname, quantityperunit, unitprice FROM products pr, categories ca WHERE pr.categoryID = ca.categoryID AND ProductName LIKE '%" + searchTerm + "%' OR CategoryName LIKE '%" + searchTerm + "%' excuse the java style in there, here it is formatted better: SELECT DISTINCT productId, productname, quantityperunit, unitprice FROM products pr, categories ca WHERE pr.categoryID = ca.categoryID AND ProductName LIKE 'Tofu' OR CategoryName LIKE 'Tofu' any help would be appreciated.

• Java - Count words in two documents

  - by user552961

  Good Morning - it is school assignment, I am not asking for any source code (if you can provide any pesudo code it would be awesome). Here is the problem :( I have to create a term frequency table. It is not pure TF, I just need to count the words and write down. I know basic steps to do it 1 - extract all terms (I can do it with file reader) 2 - remove repeating terms (I can do it with TreeMap) The output of 2nd step would be Niga, ponga, dinga, bitlo, etc. 3 - Now I have to see if there is any word in current file from above terms or not, if yes then I will count. Now this is my problem, I stucked on step 3 :( I have some idea how to count words with TreeMap (treemap.containskey etc.) but it would be global count not local count for each file :( Any pseudo code?

• Help with implementing a function to change size of dynamic array

  - by iRobot

  I'm trying to write a function that will change the size of a dynamic array to a new size. In my header file, I have: Image **images; //pointer to a dynamic array of image pointers int maximum; //size I want to do this by allocating a new array and copying the values over without changing their indices. If there are non-null pointers outside the range newmax, then we cant do this. So heres what I have: There are no compilation or runtime errors. However, I find that the new array isnt getting sized right. When I run the following test case: I should get an index out of bounds error, but instead the system lets it slide. Can anyone see the mistake? I've looked for hours but cant find anything.

• Windows 8 Set User Account Image

  - by Nexion

  I'm trying to write a small CONSOLE (not metro style) app to quickly change the user account image of the current user to a select image for a setup scrip that I'm running on a bunch of laptops. They're all Windows 8 and (since it hasn't been out terribly long) I can't find a ton of info on it. I did manage to figure out that you need to use the Windows.System.UserProfile object to do so, but I can't find any documentation on how to do so in a console app. Thoughts? Suggestions?

• Calling inheriting class methods via interface.

  - by Stacey

  Given the scenario... interface IBase{ void Process(int value); } abstract class Base : IBase { public virtual void Process(int value){ throw new NotImplementedException(); } } class Implemented: Base, IBase { public void Process(int value) { // .. some code here.. } } I'm trying to write a loop similar to the following. foreach( Base b in CollectionOfImplemented ) { b.Process( // something will go here // ); } Trying this, it keeps calling Base.Process, instead of Implemented.Process; but the type in the collection is Implemented, not Base. Boxing it seems to work, but I was hoping to see if I could find a more intelligent approach to it, since the Collection will contain other types of objects that also inherit from Base.

If I use COALESCE as an alternative, then I need to use a variable which will defeat the purpose Please help

• How to check an exectuable's path is correct in PHP?

  - by nickf

  I'm writing a setup/installer script for my application, basically just a nice front end to the configuration file. One of the configuration variables is the executable path for mysql. After the user has typed it in (for example: /path/to/mysql-5.0/bin/mysql or just mysql if it is in their system PATH), I want to verify that it is correct. My initial reaction would be to try running it with "--version" to see what comes back. However, I quickly realised this would lead to me writing this line of code: shell_exec($somethingAUserHasEntered . " --version"); ...which is obviously a Very Bad Thing. Now, this is a setup script which is designed for trusted users only, and ones which probably already have relatively high level access to the system, but still I don't think the above solution is something I want to write. Is there a better way to verify the executable path? Perhaps one which doesn't expose a massive security hole?

• Running Test framework as part of application

  - by VP

  Hi, I would like to know if it is possible in rails to run some test cases through my application. I mean, i want show the test results to users. So i was thinking to be able to call my tests through a controller and put the tests output in a dialog. Imagine that i'm doing an application where before to apply a rule, i want to run some validation tests. I could write methods in my rule model to do it, but i would like to use something like shoulda or any other kind of DSL where the "fixture" would be a record itself. Any tip or idea?

• Decoding MIME (HTML+Attachments)

  - by MH

  I'm planning to write an application that should handle incoming mails. Basically it will act more like a ticketing system than a webmail, so I'm only interested in receiving emails, and not sending them. I have made a simple prototype that downloads mails and displays the text with downloadable attachments in a web page, but handling mails from Outlook and others is more complicated. I have looked at some of the open source ticketing systems out there, but most of the code is tied to the system and is hard to separate. Is there a library that understands "rich" mail and makes this job simpler? Preferably in Python, Java, Ruby or Perl. I'm also open to suggestions for any command line mail clients that can be used for this, since the system will not receive large amounts of mail and can afford to launch external processes.

• Rails: saving a string on an object -- syntax problem?

  - by Veep

  Hey there, I am trying to write a simple function to clean a filename string and update the object. When I save a test string it works, but when I try to save the string variable I've created, nothing happens. But when I return the string, the output seems to be correct! What am I missing? def clean_filename clean_name = filename clean_name.gsub! /^.*(\\|\/)/, '' clean_name.gsub! /[^A-Za-z0-9\.\-]/, '_' clean_name.gsub!(/\_+/, ' ') #update_attribute(:filename, "test") #<-- correctly sets filename to test #update_attribute(:filename, clean_name) #<-- no effect????? WTF #return clean_name <-- seems to returns the correct string end Thank you very much.

• Oracle ORA-01795 error in Rails

  - by Cyborgo

  Hi, I am using Oracle as database for my Rails applications and have got some pretty intense tables. I'm trying to find the particular entries using a query like this Author.all( :conditions => { :name => names } ) I have been working SQlite all along and just migrated to Oracle which complains that IN clause has more than 1000 entries. Obvious workaround would be to break it into subclauses for which I need to write some raw sql queries. Is there anything in Rails that facilitate this?

• Algorithm of JavaScript "sort()" Function

  - by Knowledge Craving

  Recently when I was working with JavaScript "sort()" function, I found in one of the tutorials that this function does not sort the numbers properly. Instead to sort numbers, a function must be added that compares numbers, like the following code:- <script type="text/javascript"> function sortNumber(a,b) { return a - b; } var n = ["10", "5", "40", "25", "100", "1"]; document.write(n.sort(sortNumber)); </script> The output then comes as:- 1,5,10,25,40,100 Now what I didn't understand is that why is this occurring & can anybody please tell in details as to what type of algorithm is being used in this "sort()" function? This is because for any other language, I didn't find this problem where the function didn't sort the numbers correctly. Any help is greatly appreciated.

• Query MS Access database in VB 2008

  - by Logan

  Hi, I added an Access database as a Data Source in VB 2008. I want to query this database and use the information in various ways throughout the program. For example, there is an Employee table with first/last names of employees. I have a combobox on my form that I want to display all of the employees. So I want to query the database for all the rows in the Employee table, and add them to the combobox as I go. I am familiar with SQL Syntax, so I am not asking how to write the query itself, but rather how to fetch rows in VB code (mimicking php's mysql_fetch_assoc and mysql_connect essentially) Thanks! Edit: Also, I want to know if I can query a DB if I don't add it as a data source (if I know the path name of the database)

• Unit testing of static library that involves NSDocumentDirectory and other iOS App specific calls.

  - by Shiun

  Hi, I'm attempting to run unit tests for a static library that attempts to create/write/read a file in the document directory. Since this is a static library and not an application for the iOS, attempts to reference the NSDocumentDirectory is returning me directory for the form "/Users//Library/Application Support/iPhone Simulator/Documents" This directory does not exist. When attempting to access a directory from an actual application, the NSDocumentDirectory returns something of the form: "/Users//Library/Application Support/iPhone Simulator/4.2/FEDBEF5F-1326-4383-A087-CDA1B865E61A/Documents" (Please note the simulator version as well as application ID as part of the path) How can I overcome this shortcoming in the unit test framework for static libraries that implement tests that require iOS app specific calls? Thanks in advance.

• Multithreading - are the multi-core processors really doing parallel processing?

  - by so.very.tired

  Are the modern multi-core processors really doing parallel processing? Like, take for example, Intel's core i7 processors. some of them has #of Cores: 4 and #of Threads: 8 (taken from Intel's specifications pages). If I to write a program (say in Java or C) that has multiple threads of execution, will they really be processed concurrently? My instructor said that "it is not always the case with multi-core processors", but didn't gave to much details. And why do Intel have to specify both #of Cores and #of Threads? Isn't thread just a term that describe a program-related abstraction, unlike "cores" which are actual hardware? ("Every thread runs on different core").

• INSERT INTO othertbl SELECT * tbl

  - by Harry

  Current situation: INSERT INTO othertbl SELECT * FROM tbl WHERE id = '1' So i want to copy a record from tbl to othertbl. Both tables have an autoincremented unique index. Now the new record should have a new index, rather then the value of the index of the originating record else copying results in a index not unique error. A solution would be to not use the * but since these tables have quite some columns i really think it's getting ugly. So,.. is there a better way to copy a record which results in a new record in othertbl which has a new autoincremented index without having to write out all columns in the query and using a NULL value for the index. -hope it makes sense....-

• How to edit files on the users file system from my web server?

  - by Abs

  Hello all, I am really looking for implementation advice as I have entered a new realm that I am not familiar with. At the simplest level, I would like to find a way that I can read/write to a users machine from my web server. For this to work, I think I will have to install some sort of "plugin" on the users machine which can receive (or poll?) the server for instructions. The above is the line of thought that I currently have, maybe using JAVA to do this. This needs to work on Linux, Mac and Windows OS. I am really looking for advice on the above, is it a good idea? Is there a better way of doing this? Is there something out there already that I can build on top of? I really appreciate all input and advice as this is something I have not done before. Thanks all

• Makefile won't copy .o to obj/ and target to bin/ folders

  - by about blank

  I'm trying to write a Makefile which will copy its target and objects to bin/ and obj/ directories, respectively. Yet, when I try to run it I get the following error: nasm -f elf64 -g -F stabs main.asm -l spacelander.lst ld -o spacelander obj/main.o ld: cannot find obj/main.o: No such file or directory make: *** [spacelander] Error 1 Why is this happening? Update I noticed when I posted the error that it was due to white spacing errors. After taking care of those, I still get the new error I replaced with the old one I mentioned prior. What is this?? Update 2 Posted -d flag output below Makefile source.

• Constructor initialising an array of subobjects?

  - by ojw

  Say I have several objects within a class, each of which needs constructing with a different value. I can write something like this: class b { public: b(int num) { // 1 for a.b1, and 2 for a.b2 } }; class a { public: b b1; b b2; a() : b1(1), b2(2) { } }; However, is it possible to do the same thing if those multiple objects are stored in an array? My first attempt at it doesn't compile: class a { public: b bb[2]; a() : bb[0](1), bb[1](2) { } };

• Javascript: Retrieve Object Property Names

  - by Jason

  I'm trying to write a function that needs to know the property names of an object being passed in, like so: var data = { "key1":"value1", "key2":"value2", etc} ^ i want the string value "key1" How do I retrieve the string "key1" from data? I know I can set a property dynamically like data[prop]=value but i want to know what prop is from an object passed in. If that doesn't make sense I suppose I could try to explain more. Thanks! I eventually want to do something like: for (var i = 0; i<data.length; i++) { var name = data[i].getPropertyName() <--- not a real function // do stuff }
