• choose append to existing backup instead of overwrite

  - by aron

  Hello, I have a database and I made it's first backup 2 days ago. Then yesterday I spent an entire adding new records. This morning I ran a backup, (but I selected append to existing backup set) as pictured below. I just ran a restore and I found that it wiped out all my data from yesterday and it restored it from the backup of 2 days ago. Not the version from this mornings backup. I zipped this backup file to be safe. I changed some data in the DB, Then I ran the back up again, but this time I selected "overwrite all existing backup sets" Now when I restore the db it's seems to restore the data from the backup correctly. I think I learned a lesson here, correctly if I'm wrong My questions is, Did I lose an entire day of work? I still have this morning's backup .bak file safe in a zip. Is there anyway I can restore is with the right data?

• Maven workspace resolution horked

  - by user237815

  I'm using m2eclipse to manage maven projects. Somehow I did a bad thing, and now the system is behaving as if workspace resolution is disabled. I have several projects that depend on a main project. This project has a version of 4.0-SNAPSHOT, and all the dependent projects reference it in the dependencies section of their poms. Everything was working fine until I created an entirely new project and mistakenly copied the pom from the main project into the new project. Suddenly, all of the dependent projects got the error: "The container 'Maven Dependencies" references non existing library C:\users\myusername.m2\com\mydomain\myproject\4.0-SNAPSHOT\myproject-4.0-SNAPSHOT.jar I zapped the offending new project, but the error remains for all the dependent projects. I've made no changes (to my knowledge) in the main project or any of the dependent projects, so I'm guessing something got changed in the Eclipse environment. Does m2eclipse or Maven itself maintain settings anywhere that I can blow away?

• frequent updates of a Tomcat application

  - by Erel Segal Halevi

  I have an application that runs on a Tomcat 7 server on a Windows machine. In its current stage, I have to frequently update and fix it. Whenever I need to update the application, I do all this: Build a new war file; Go to the Windows server, stop the Tomcat service; download the file, put it under webapps; Remove the old application folder under webapps; Remove the old application folder under work/Catalina/localhost (otherwise it keeps the old version cached). Restart the Tomcat service. I am sure there is a way to do all this automatically. What is it?

• How to avoid StaleObjectStateException when transaction updates thousands of entities?

  - by ThinkFloyd

  We are using Hibernate 3.6.0.Final with JPA 2 and Spring 3.0.5 for a large scale enterprise application running on tomcat 7 and MySQL 5.5. Most of the transactions in application, lives for less than a second and update 5-10 entities but in some use cases we need to update more than 10-20K entities in single transaction, which takes few minutes and hence more than 70% of times such transaction fails with StaleObjectStateException because some of those entities got updated by some other transaction. We generally maintain version column in all tables and in case of StaleObjectStateException we generally retry but since these longs transactions are anyways very long so if we keep on retrying then also I am not very sure that we'll be able to escape StaleObjectStateException. Also lot of activities keep updating these entities in busy hours so we cannot go with pessimistic approach because it can potentially halt many activities in system. Please suggest how to fix such long transaction issue because we cannot spawn thousands of independent and small transactions because we cannot afford messed up data in case of some failed & some successful transactions.

• Crowdsourcing translation for mobile developers?

  - by superg

  I am developing applications for mobile phones with different operating systems (Android, Symbian, iPhone). Applications are sold internationally so they need to be translated to different languages in addition to english version. I assume most mobile developers do the translations using some paid external service each time. This approach does not look very cost-effective to me. Would it make sense to have a website where simple translations would be done using crowdsourcing (other developers)? Most strings in mobile applications are very simple and short, for example "OK, "Cancel", "Are you sure?", "Please enter your password". Also the same strings are used in hundreds of applications. Instead of paying for translating all strings, developers could save money by only buying their difficult application specific translations. Does anyone agree with this idea? I have seen many opensource projects doing the translations succesfully using volunteers.

• Entity Framework 5 upgrade from 4

  - by user1714591

  I'm having an issue with the Where clause in a search, in my original version EF4 I could add a Where clause with 2 parameters, the where clause (string predicate) and a ObjectParameter list such as var query = context.entities.Where(WhereClause.ToString(), Params.ToArray()); since my upgrade to EF5 I don't seem to have that option am I missing something? This was originally used to build dynamic where clause such as "it.entity_id = @entity_id" then holding the variable value in the ObjectParameter. I'm hoping I don't have to rewrite all the searches that have been built out this way, so any assistance would be greatly appreciated. Cheers

• Is it possible to dither a gradient drawable?

  - by Seu

  I'm using the following drawable: <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" > <gradient android:startColor="@color/content_background_gradient_start" android:endColor="@color/content_background_gradient_end" android:angle="270" /> </shape> The problem is that I get severe banding on hdpi devices (like the Nexus One and Droid) since the gradient goes from the top of the screen to the very bottom. According to http://idunnolol.com/android/drawables.html#shape_gradient there isn't a "dither" attribute for a gradient. Is there anything I can do to smooth the gradient?

• Can anyone tell me what is wrong with my create trigger syntax?

  - by Travis

  I am experimenting with triggers for the first time. When I try to create a trigger using the following: CREATE TRIGGER t_foldersPrivate BEFORE DELETE ON foldersPrivate FOR EACH ROW BEGIN DELETE FROM programs WHERE folderType = '0' AND folderID = OLD.ID; END; I receive the following error: `1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 3` (mysql 5.1.37) If I get rid fo the delete statement the create trigger statement works fine. So I am assuming it must have something to do with that. But for the life of me I'm not sure what...

• how to use php to include an image in a word file?

  - by altvali

  Hi all! Somebody has asked me to make an app in php that will generate a .doc file with an image and a few tables in it. My first approach was: somethingsomething else cevaaltceva'); fclose($fh); ? This uses the data uri technique of embedding an image. This will generate an html file that will be rendered ok in web browsers but the image is missing in Microsoft Office Word, at least in the standard setup. Then, while editing the file with Word, i've replace the image with an image from file and Microsoft Word changed the contents of the file into Open XML and added a folder, new_files where he put the imported image (which was a .png), a .gif version of the image and a xml file: Now this isn't good enough either since i want this to be all kept in a single .doc file. Is there a way to embed an image in an OpenXML-formatted .doc file? Any help will be much appreciated.

• IE's responseXML.getElementsByTagName() unable to handle non English character ?

  - by trix

  I have a javascript that does this (http is your XMLHttpRequest object) var r = http.responseXML.getElementsByTagName('item'); The issue is variable r is always an empty list if the response contains non-English character (r.length is 0). The response header is correctly set Content-Type: text/xml;charset=ISO-8859-1 This is what the response from the webserver looks like <?xml version='1.0' encoding='UTF-8'?> <d> <r> <item value="jmob" label="John Möb"/> </r> </d> It happens only in IE (both IE6 and IE8), works in Firefox and Chrome. If items contain only English characters, it works fine. Is there a workaround for this ?

• WiX: .Net 3.5 prerequisite

  - by Mike Pateras

  I have a WiX installer that I would like to check for .Net 3.5, and install it if it does not exist. I have the following lines in my wixproj file: <BootstrapperFile Include="Microsoft.Net.Framework.3.5"> <ProductName>.NET Framework 3.5</ProductName> </BootstrapperFile> <BootstrapperFile Include="Microsoft.Windows.Installer.3.1"> <ProductName>WIndows Installer 3.1</ProductName> </BootstrapperFile> When I create the installer, a DotNetFX35 folder is created, and in it are 4 different versions of .Net (including 3.5), and an installer file. I have two questions: How do I have it only bring in version 3.5 (so that the user doesn't have to install 100+ MB of files)? How do I tell WiX to package these files up into the MSI file, so that the user only has to download 1 file?

• Windows Mobile application icon

  - by Andy White

  Is it possible to specify the application icon for a windows mobile app from a resource file or other configuration besides the .csproj? The reason I would like to do this is because I have an application that can be configured to run in several different ways. We would like to build out three unique .cabs based on these configurations, and we would like to use a different icon for each version. One option we've considered is just running multiple builds and swapping out the icon file each time, but we were hoping there would be a way to do this using a "resource" DLL or something along those lines, that could be compiled or linked in to the main .exe.

• MySQL order by error in PHP

  - by theflyinghaiwian

  Hi, I'm making a simple cms system for a site I'm making for non-tech users to edit... So far so good but when I try and run this code I keep getting: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''pages' ORDER BY 'pages'.'pageOrder' ASC LIMIT 0 , 30' at line 1 By the error it looks like a problem with the order by section and indeed it works without it... $sql = "SELECT * FROM 'pages' ORDER BY 'pages'.'pageOrder' ASC LIMIT 0 , 30"; $result = mysql_query($sql) or die(mysql_error()); Now I know there is nothing wrong with the code because originally I wrote my own SQL but then after it failed I robbed some from phpmyadmin and it still gives the error but it works in phpmyadmin... I'm really at my wits end with this, help is very much appreciated thank you...

• Rotate view of PDF on a WinForm

  - by Dabas

  I have to display a PDF inside a winform (c# on .net 2.0 framework). For now, I am using the ActiveX PDF control provided by Adobe. I have to disable the entire control so that a user can't print or save via right-click or hotkeys. Unfortunately, many of the documents need to be rotated (just viewed, not permanently saved that way). I'd like to allow them to rotate the view by pressing a button control. I've tried enabling the control then programmatically sending the hotkeys (ctrl shift +) using SendKeys and SendInput but the timing issues make this a non-viable solution. I've asked on the proper Adobe boards and they said it was not possible being that all of my clients will only have the reader version installed.

• How do I crash the App Pool?

  - by willem

  Our ASP.NET 2 web application handles exceptions very elegantly. We catch exceptions in Global ASAX in Application_Error. From there we log the exception and we show a friendly message to the user. However, this morning we deployed the latest version of our site. It ran ok for half an hour, but then the App Pool crashed. The site did not come back up until we restored the previous release. How can I make the app pool crash and skip the normal exception handler? I'm trying to replicate this problem, but with no luck so far. Update: we found the solution. One of our pages was screenscraping another page. But the URL was configured incorrectly and the page ended up screenscraping itself infinitely, thus causing a stack overflow exception.

• How to use JNI, but only when available for current platform?

  - by Mecki

  What is the common way (or best practice) to optionally use JNI? E.g. I have a Java class and this class is 100% pure Java, so it can run on all platforms. However, on some platforms I'd like to speed up some heavy calculations using JNI - which works fine. Unfortunately I cannot support any existing Java platform in the world. So I guess it is fine to initially only support the big three: Linux, Windows, Mac OS X. So what I'd like to do is to use JNI on those three platforms and use the 100% pure Java version on all other platforms. Now I can think of various ways how to do that (loading class dynamically for example and either loading the JNI class or the pure Java one), but thinking that this is a common issue that thousands of projects had to solve in the past for sure, I'm really surprised to not find any documentation or references to the question how to solve this most elegantly or effectively.

• Warn user of .NET Framework requirements

  - by moogs

  So I have an app (tool) that uses .NET 3.0. When run on a machine that only has .NET 2.0 (like the default Server 2008 R2 install) it crashes miserably. What I've seen so far is that people are using a shunt that will first check the .NET version. Is there a way to build it or add some manifest somehow so that the user is warned of this problem (and hopefully be prompted to install .NET)? I know this can be solved by an installer, but I have requirements that need it to be a standalone executable.
