  • Testing on blackberry device - adding and removing app multiple times

    - by Kai
    It would be useful for many people to know how to completely remove an application from your device when testing. I have downloaded my app many times now, and likewise have deleted it many times. The problem is when deleting the app, it does not remove things like the persistent object related to my app, or the images downloaded through the app. So, when I download the next build, I have no idea if something broke that is related to building the persistent object or fetching the images since those elements already exist from the last build. I don't know if this is a cache thing. I don't know if this is expected and I have to use some utility to wipe this data after deleting the app. I can't really find much info through basic web searches. Any information would be appreciated. Blackberry Bold 9000. 4.6 OS. tested with both SD card and no SD card.

  • POST and multiple submit buttons on form (iphone)

    - by Jonathan
    NSString *reqURL = [NSString stringWithFormat:@"%@/login",SERVER_URL]; NSMutableURLRequest *req = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:reqURL]]; [req setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"]; NSData *myRequestData = [NSData dataWithBytes:[@"username=whatever&password=whatever" UTF8String] length: [@"username=whatever&password=whatever" length]]; [req setHTTPMethod: @"POST"]; [req setHTTPBody: myRequestData]; NSData *returnData = [NSURLConnection sendSynchronousRequest:req returningResponse: nil error: nil]; NSString *html = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; I got this code from another question I asked. But what happens if there is more than one submit button. I really have no idea how to ask this question. An example of such situation is on the logout page for this site. There are no fields to enter data into, but there are 2 submit buttons. How can I "simulate clicking" on one of those buttons using code like the above (so not using a UIWebView)

  • A btter way to represent Same value given multiple values(C#3.0)

    - by Newbie
    I have a situation for which I am looking for a more elegant solution. Consider the below cases "BKP","bkp","book-to-price" (will represent) BOOK-TO-PRICE "aop","aspect oriented program" (will represent) ASPECT-ORIENTED-PROGRAM i.e. if the user enter BKP or bkp or book-to-price , the program should treat that as BOOK-TO-PRICE. The same holds good for the second example(ASPECT-ORIENTED-PROGRAM). I have the below solution: Solution: if (str == "BKP" || str == "bkp" || str == "book-to-price" ) return "BOOK-TO-PRICE". But I think that there can be many other better solutions . Could you people please give some suggestion.(with an example will be better) I am using C#3.0 and dotnet framework 3.5

  • Multiple Exception Handling in one if statement [closed]

    - by JA3N
    I am having trouble with throwing and catching exceptions. Here is the code for assignSeat(), assignSeat is called in a try block in another class. void assignSeat(String passengerName, int x, int y) throws SeatOccupiedException, InvalidPassengerNameException { Seat tSeat = airplane.getSeat(x,y); if (tSeat!=null) { if (passengerName.isEmpty() || !passengerName.matches("[a-zA-Z]+")) { throw new InvalidPassengerNameException(); } //excluded else if else if (foundPassenger(passengerName)) { airplane.seatList.get(airplane.seatNumber(passengerName)).unOccupy(); tSeat.occupy(); for (int i = 0; i<passengers.size();i++) if (passengers.get(i).getName().equals(passengerName)) passengers.get(i).changeSeat(tSeat.getSeatName()); } else if (!tSeat.occupied) { tSeat.occupy(); addPassenger(passengerName, tSeat.getSeatName()); } else if (tSeat.occupied) { throw new SeatOccupiedException(); } } and here is the code that calls assignSeat() and is in another class (I won't copy the whole class to make it look clearer) if (afComp.currentAF != null) { try { afComp.currentAF.assignSeat(nameField.getText(), x, y); //<-Problem here, "Unhandled exception type SeatOccupiedException" } catch (SeatOccupiedException exception) //<-Problem here, "Unreachable catch block, This exception is never thrown from the try statement body" { } catch(InvalidPassengerNameException exception) //<-No problems. { } } Whats wrong with the try block? why won't it throw the SeatOccupiedException? Exception classes: SeatOccupied: package a2; public class SeatOccupiedException extends Exception { public SeatOccupiedException(){} } InvalidPassengerName: package a2; public class InvalidPassengerNameException extends Exception { public InvalidPassengerNameException() {} } Every class I have is in package a2 imports for class that calls assignSeat package a2; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.MouseListener; import java.awt.event.MouseMotionListener; import java.awt.event.MouseEvent; import java.awt.BorderLayout; import javax.swing.*; import javax.swing.event.*; imports for class that has assignSeat package a2; import java.util.ArrayList;

  • Multiple flash video players on w3c-valid page is slow

    - by vect
    I have a web site that displays a column of flash videos. The page is w3c-valid. The problem is that the page loads very slowly and sometimes crashes my web browser. Until the page is fully loaded, the videos are slow to respond and play. Is there a way to make these videos load their preview images only? What should I do to speed the page up? The videos are 360x264.

  • Read multiple strings from a file C++

    - by user69514
    Hi I need to read different values stored in a file one by one. So I was thinking I can use ifstream to open the file, but since the file is set up in such a way that a line might contain three numbers, and the other line one number or two numbers I'm not sure how to read each number one by one. I was thinking of using stringstream but I'm not sure if that would work. The file is a format like this. 52500.00 64029.50 56000.00 65500.00 53780.00 77300.00 44000.50 80100.20 90000.00 41000.00 60500.50 72000.00 I need to read each number and store it in a vector. What is the best way to accomplish this? Reading one number at a time even though each line contains a different amount of numbers?

  • Css Multiple background-color

    - by Khanh TO
    I'm a novice in Css and it's difficult to search for this specific case on the internet, so I post a question here. I'm working on an existing code base and I see something like this. li { background-color: #000 \9; background-color: rgba(0, 0, 0, 0); } I don't understand the meaning of \9. But it looks to me they are duplicates and I should remove one of them. Could you please explain the \9 and should I remove one of them? Thanks.

The problem I have is that it plots funny as shown below:

  • Extracting RAR archive into multiple directories on Windows

    - by user368565
    Hello, On a Windows box, I need to extract a RAR archive so that individual files in it go into specific directories. I can provide, say, a text file that lists each file and the target directory for it. Then I need help creating a batch file that will actually extract these files into their target locations. Please help. E.g. RAR archive x.rar contains a.a b.b c.c Text file x.txt says a.a C:\foo b.b C:\bar c.c C:\foo Result of running batch file on x.rar and x.txt should be: in C:\foo we have a.a and c.c in C:\bar we have b.b Thanks!

  • Trying to run multiple HTTP requests in parallel, but being limited by Windows (registry)

    - by Nailuj
    I'm developing an application (winforms C# .NET 4.0) where I access a lookup functionality from a 3rd party through a simple HTTP request. I call an url with a parameter, and in return I get a small string with the result of the lookup. Simple enough. The challenge is however, that I have to do lots of these lookups (a couple of thousands), and I would like to limit the time needed. Therefore I would like to run requests in parallel (say 10-20). I use a ThreadPool to do this, and the short version of my code looks like this: public void startAsyncLookup(Action<LookupResult> returnLookupResult) { this.returnLookupResult = returnLookupResult; foreach (string number in numbersToLookup) { ThreadPool.QueueUserWorkItem(lookupNumber, number); } } public void lookupNumber(Object threadContext) { string numberToLookup = (string)threadContext; string url = @"http://some.url.com/?number=" + numberToLookup; WebClient webClient = new WebClient(); Stream responseData = webClient.OpenRead(url); LookupResult lookupResult = parseLookupResult(responseData); returnLookupResult(lookupResult); } I fill up numbersToLookup (a List<String>) from another place, call startAsyncLookup and provide it with a call-back function returnLookupResult to return each result. This works, but I found that I'm not getting the throughput I want. Initially I thought it might be the 3rd party having a poor system on their end, but I excluded this by trying to run the same code from two different machines at the same time. Each of the two took as long as one did alone, so I could rule out that one. A colleague then tipped me that this might be a limitation in Windows. I googled a bit, and found amongst others this post saying that by default Windows limits the number of simultaneous request to the same web server to 4 for HTTP 1.0 and to 2 for HTTP 1.1 (for HTTP 1.1 this is actually according to the specification (RFC2068)). The same post referred to above also provided a way to increase these limits. By adding two registry values to [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings] (MaxConnectionsPerServer and MaxConnectionsPer1_0Server), I could control this myself. So, I tried this (sat both to 20), restarted my computer, and tried to run my program again. Sadly though, it didn't seem to help any. I also kept an eye on the Resource Monitor (see screen shot) while running my batch lookup, and I noticed that my application (the one with the title blacked out) still only was using two TCP connections. So, the question is, why isn't this working? Is the post I linked to using the wrong registry values? Is this perhaps not possible to "hack" in Windows any longer (I'm on Windows 7)? Any ideas would be highly appreciated :) And just in case anyone should wonder, I have also tried with different settings for MaxThreads on ThreadPool (everyting from 10 to 100), and this didn't seem to affect my throughput at all, so the problem shouldn't be there either.

  • Multiple left joins, how to output in php

    - by Dan
    I have 3 tables I need to join. The contracts table is the main table, the 'jobs' and 'companies' table are extra info that can be associated to the contracts table. so, since I want all entries from my 'contracts' table, and the 'jobs' and 'companies' data only if it exists, I wrote the query like this.... $sql = "SELECT * FROM contracts LEFT JOIN jobs ON contracts.job_id = jobs.id LEFT JOIN companies ON contracts.company_id = companies.id ORDER BY contracts.end_date"; Now how would I output this in PHP? I tried this but kept getting an undefined error "Notice: Undefined index: contracts.id"... $sql_result = mysql_query($sql,$connection) or die ("Fail."); if(mysql_num_rows($sql_result) > 0){ while($row = mysql_fetch_array($sql_result)) { $contract_id = stripslashes($row['contracts.id']); $job_number = stripslashes($row['jobs.job_number']); $company_name = stripslashes($row['companies.name']); ?> <tr id="<?=$contract_id?>"> <td><?=$job_number?></td> <td><?=$company_name?></td> </tr> <? } }else{ echo "No records found"; } Any help is appreciated.

  • Storing/Quering multiple value in SQLite

    - by chmod
    I'm trying to store a blooming season in month for each tree in SQLite3. Currently I had the field "month" then I store the month name in the field. For example Tree Name Month Tree1 Jan,Feb,Mar Tree2 Nov,Dec,Jan Tree3 Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec Tree4 Mar,Apr,Nov,Dec Tree5 Jan,Feb,Mar,Apr I'm not sure if this is the best way to store it, Any recommendation is appreciate. Secondly, I need to perform a query where I enter in the month and it should return me the tree name that match the search criteria. For example If I search for "Jan" the result should be Tree1,Tree2,Tree3,Tree5 "Jan,Feb,Mar" the result should be Tree1,Tree3,Tree5 "Jan,Feb,Mar,Apr" the result should be Tree5 "Sep,Oct,Nov,Dec" the result should be none Which SQL query do I have to use in order to obtain the above result?

  • oracle select query - index on multiple columns

    - by CC
    Hello. I'm working on a sql query, and trying to optimise it, because it takes too long to execute. I have a few select and UNION between. Every select is on the same table but with different condition in WHERE clause. Basically I have allways something like : select * from A where field1 <"toto" and field2 IN (...) UNION select * from A where field1 >"toto2" and field2 =(...) UNION .... I have a index on field1 (it a date field, and field2 is a number). Now, when I do the select and if I put only WHERE field1 <'12/12/2010' it does not use the index. I'm using Toad to see the explain plain and it said: SELECT STAITEMENT Optimiser Mode = CHOOSE TABLE ACCESS FULL It is a huge table, and the index on this column is there. Any idea about this optimiser ? And why it does not uses the index ? Another question is , if I have where clause on field1 and field2 , I have to create only one index, or one index for each field ? Thanks alot.

  • Radius of multiple latitude/longitude points

    - by zekial
    I have a program that takes as input an array of lat/long points. I need to perform a check on that array to ensure that all of the points are within a certain radius. So, for example, the maximum radius I will allow is 100 miles. Given an array of lat/long (coming from a MySQL database, could be 10 points could be 10000) I need to figure out if they will all fit in a circle with radius of 100 miles. Kinda stumped on how to approach this. Any help would be greatly appreciated.

  • linq Multiple Where based on conditions.

    I want to query a table with some conditions based on user input. I wrote this : IQueryable turnoQuery = dc.Turno; if (helper.FechaUltimaCitaDesde != DateTime.MinValue) { turnoQuery = turnoQuery.Where(t => t.TurnoFecha >= helper.FechaUltimaCitaDesde); } if (helper.FechaUltimaCitaHasta != DateTime.MinValue) { turnoQuery = turnoQuery.Where(t => t.TurnoFecha <= helper.FechaUltimaCitaHasta); } if (helper.SoloCitasConsumidas) { turnoQuery = turnoQuery.Where(t => t.Estado == Convert.ToInt32(EnmEstadoDelTurno.Consumido)); } else if(helper.AnuladoresDeCitas) { turnoQuery = turnoQuery.Where(t => t.Estado == Convert.ToInt32(EnmEstadoDelTurno.Cancelado) || t.Estado == Convert.ToInt32(EnmEstadoDelTurno.Ausente)); } The problem I'm having is that the "where" clause gets stepped over with the last one. Whats the correct way to do something like this on LINQ? The "helper" object is a custom class storing the user input dates for this example.

  • Performing centralized authorization for multiple applications

    - by Vaibhav
    Here's a question that I have been wrestling with for a while. We have a situation wherein we have a number of applications that we have created. These have grown organically over a period of time. All of these applications have permissions code built into them that controls access to various parts of the application depending on whether the currently logged in user has the necessary permissions or not. Alongside these applications is a utility application which allows an administrator to map users to permissions for all applications - the way it works is that every application has code which reads this external database of the said utility application to check if the currently logged in user has the necessary permission or not. Now, the question is this. Should the user-permissions mapping information reside in and be owned by the applications themselves, or is it okay to have this information reside within an external entity/DB (as in this case the utility application's database). Part of me thinks that application permissions are very specific to the application context itself, so shouldn't be separated from the application itself. But I am not sure. Any comments?

  • 1-st level routes for multiple resources in Rails

    - by Leonid Shevtsov
    I have a simple SEO task. There's a City model and a Brand model, and I have to create 1st-level URLs for both (e.g. site.com/honda and site.com/boston). What's the preferred routing/controller combination to do this in Rails? I can only think of map.connect '/:id', :controller => 'catchall', :action => 'index' class CatchallController < ApplicationController def index if City.exists?(:slug => params[:id]) @city = City.find_by_slug!(params[:id]) render 'cities/show' else @brand = Brand.find_by_slug!(params[:id]) render 'brands/show' end end end but it seems to be very un-Rails to put such logic into the controller. (Obviously I need to make sure that the slugs don't overlap in the models, that's done).
