• Java runs out of memory, even though I give it plenty!

  - by spitzanator

  Hey, folks. So, I'm running a java server (specifically Winstone: http://winstone.sourceforge.net/ ) Like this: java -server -Xmx12288M -jar /usr/share/java/winstone-0.9.10.jar --useSavedSessions=false --webappsDir=/var/servlets --commonLibFolder=/usr/share/java This has worked fine in the past, but now it needs to load a bunch more stuff into memory than it has before. The odd part is that, according to 'top', it has 15.0g of VIRT(ual memory) and it's RES(ident set) is 8.4g. Once it hits 8.4g, the CPU hangs at 100% (even though it's loading from disk), and eventually, I get Java's OutOfMemoryError. Presumably, the CPU hanging at 100% is Java doing garbage collection. So, my question is, what gives? I gave it 12 gigs of memory! And it's only using 8.2 gigs before it throws in the towel. What am I doing wrong? Oh, and I'm using java version "1.6.0_07" Java(TM) SE Runtime Environment (build 1.6.0_07-b06) Java HotSpot(TM) 64-Bit Server VM (build 10.0-b23, mixed mode) on Linux. Thanks, Matt

• Unable to change URL for .NET reference to dynamic web service

  - by Malvineous

  Hi all, I have a web reference added to a C# .NET project. The URL for the web reference needs to change depending on whether I'm building for a development, staging or production environment. I've set the web service to be dynamic, which supposedly means it takes the URL from my app.config file. When I perform a build it overwrites the app.config with the required file which contains the correct URL (different file for each of dev/staging/production.) I then go into the solution properties and make sure the Settings.settings file is updated with the app.config changes. However when I view the properties for the web service, it is still showing the old URL, despite it being dynamic, and supposed to be reading from my settings file (even after closing and reopening the project/solution.) The app.config and the settings file all have the new URL, but the web reference doesn't notice it has changed. If I do a build it ignores the URL in the settings file and tries to connect to the last URL manually typed into the web reference's properties. Typing a URL into these properties correctly updates the app.config and .settings files, so the link is definitely there. I'm a bit new to .NET but it seems to me the purpose of setting the service to be dynamic is so that you can change the URL elsewhere, but when I do this it just gets ignored! Am I doing something wrong?

• Java: easiest way to package both Java 1.5 and 1.6 code

  - by WizardOfOdds

  I want to package a piece of code that absolutely must run on Java 1.5. There's one part of the code where the program can be "enhanced" if the VM is an 1.6 VM. Basically it's this method: private long[] findDeadlockedThreads() { // JDK 1.5 only supports the findMonitorDeadlockedThreads() // method, so you need to comment out the following three lines if (mbean.isSynchronizerUsageSupported()) return mbean.findDeadlockedThreads(); else return mbean.findMonitorDeadlockedThreads(); } What would be easiest way to have this compile on 1.5 and yet do the 1.6 method calls when on 1.6 ? In the past I've done something similar by compiling a unique 1.6 class that I would package with my app and instantiate using a ClassLoader when on 1.6 (because an 1.6 JVM is perfectly fine mixing 0x32 and 0x31 classes), but I think it's a bit overkill (and a bit painful because during the build process you have to build both 0x31 and 0x32 .class files). How should I go if I wanted to compile the above method on 1.5? Maybe using reflection but then how (I'm not familiar at all with reflection) Note: if you're curious, the above method comes from this article: http://www.javaspecialists.eu/archive/Issue130.html (but I don't want to "comment the three lines" like in the article, I want this to compile and run on both 1.5 and 1.6)

• Moving .NET assemblies away from the application base directory?

  - by RasmusKL

  I have a WinForms application with a bunch of third party references. This makes the output folder quite messy. I'd like to place the compiled / referenced dlls into a common subdirectory in the output folder, bin / lib - whatever - and just have the executables (+ needed configs etc) reside in the output folder. After some searching I ran into assembly probing (http://msdn.microsoft.com/en-us/library/4191fzwb.aspx) - and verified that if I set this up and manually move the assemblies my application will still work if they are stored in the designated subdirectory like so: <configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="bin" /> </assemblyBinding> </runtime> </configuration> However, this doesn't solve the build part - is there any way to specify where referenced assemblies and compiled library assemblies go? Only solutions I can think of off the top of my head is either post-build actions or dropping the idea and using ILMerge or something. There has got to be a better way of defining the structure :-)

• Extracting a .app from a zip file in Python, using ZipFile

  - by Yakattak

  I'm trying to extract new revisions of Chromium.app from their snapshots, and I can download the file fine, but when it comes to extracting it, ZipFile either extracts the chrome-mac folder within as a file, says that directories don't exist, etc. I am very new to python, so these errors make little sense to me. Here is what I have so far. import urllib2 response = urllib2.urlopen('http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/LATEST') latestRev = response.read() print latestRev # we have the revision, now we need to download the zip and extract it latestZip = urllib2.urlopen('http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/%i/chrome-mac.zip' % (int(latestRev)), '~/Desktop/ChromiumUpdate/%i-update' % (int(latestRev))) #declare some vars that hold paths n shit workingDir = '/Users/slehan/Desktop/ChromiumUpdate/' chromiumZipPath = '%s%i-update.zip' % (workingDir, (int(latestRev))) chromiumAppPath = 'chrome-mac/' #the path of the chromium executable within the zip file chromiumAppExtracted = '%s/Chromium.app' % (workingDir) # path of the extracted executable output = open(chromiumZipPath, 'w') #delete any current file there output.write(latestZip.read()) output.close() # we have the .zip now we need to extract the Chromium.app file, it's in ziproot/chrome-mac/Chromium.app import zipfile, os zippedFile = open(chromiumZipPath) zippedChromium = zipfile.ZipFile(zippedFile, 'r') zippedChromium.extract(chromiumAppPath, workingDir) #print zippedChromium.namelist() zippedChromium.close() #zippedChromium.close() Any ideas?

• How to setup Continuous Integration and Continuous Deployment for Django projects?

  - by ycseattle

  Hello, I am researching about how to set up CI and continuous deployment for a small team project for a Django based web application. Here are needs: Developer check in the code into a hosted SVN server (unfuddle.com) A CI server detects new checkin, check out the source, build, run functional tests. If tests all passed, deploy the code to the webserver on Amazon EC2. For now, the CI server is also responsible to run the functional tests. I figured out that I can use Husdon as the CI server, use Selenium to run functional tests, and use Fabric to deploy the build to remote web server in Amazon cloud. I am new to Django development and not very familiar with opensource tools. My questions are: I can find some information to integrate hudson with selenium, but I couldn't find much information on how to integrate Fabric to Hudson as well. Is this setup viable? Do you see problems? How do I integrate and deploy database changes? Most likely in the early stage we will change database schema very often with code changes. I used to use Visual Studio and the database project made it very simple to deploy. I wonder if there is "established, well-supported" way to do that. Thanks!!

• What would be better in my case - apache, nginx or lighttpd ?

  - by The Devil

  Hey everybody, I'm writing a php site that's expected to get about 200-300 concurrent users browsing it. When initializing the application will load about 30 php classes, some 10 maybe 15 images and a couple of css files. So my question is what else can I do (except optimizing my code and using apc/eaccelerator for php) to get as close as possible to those numbers of concurrent users ? Currently we haven't chosen a server for the site to be hosted on but most probably it'll be a VPS Dual core + 2 or maybe 4gb ram. Is it possible for such a server to handle that load ? Also how could I test it myself and be sure that it'll be able to handle it ? Thanks in advance, Me

• g++ Linking Error on Mac while compiling FFMPEG

  - by Saptarshi Biswas

  g++ on Snow Leopard is throwing linking errors on the following piece of code test.cpp #include <iostream> using namespace std; #include <libavcodec/avcodec.h> // required headers #include <libavformat/avformat.h> int main(int argc, char**argv) { av_register_all(); // offending library call return 0; } When I try to compile this using the following command g++ test.cpp -I/usr/local/include -L/usr/local/lib \ -lavcodec -lavformat -lavutil -lz -lm -o test I get the error Undefined symbols: "av_register_all()", referenced from: _main in ccUD1ueX.o ld: symbol(s) not found collect2: ld returned 1 exit status Interestingly, if I have an equivalent c code, test.c #include <stdio.h> #include <libavcodec/avcodec.h> #include <libavformat/avformat.h> int main(int argc, char**argv) { av_register_all(); return 0; } gcc compiles it just fine gcc test.c -I/usr/local/include -L/usr/local/lib \ -lavcodec -lavformat -lavutil -lz -lm -o test I am using Mac OS X 10.6.5 $ g++ --version i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664) $ gcc --version i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664) FFMPEG's libavcodec, libavformat etc. are C libraries and I have built them on my machine like thus: ./configure --enable-gpl --enable-pthreads --enable-shared \ --disable-doc --enable-libx264 make && sudo make install As one would expect, libavformat indeed contains the symbol av_register_all $ nm /usr/local/lib/libavformat.a | grep av_register_all 0000000000000000 T _av_register_all 00000000000089b0 S _av_register_all.eh I am inclined to believe g++ and gcc have different views of the libraries on my machine. g++ is not able to pick up the right libraries.

• Loading a helper elsewhere than the autoload.php?

  - by drpcken

  I inherited a project and I'm cleaning up a bit and trying to finish it. I noticed that they used (or wrote) a breadcrumb helper. It is in my helpers folder and is named breadcrumb_helper.php It has a single function to build a breadcrumb menu with links and pass it to the view breadcrumbs.php. Here's the code: function show_breadcrumbs() { $ci =& get_instance(); $ci->load->helper('inflector'); $data = ''; //build breadcrumb and store in $data $this->load->view("breadcrumbs", $data) } I was trying to figure out how this helper worked and I checked the autoload.php but there is no reference to the helper in there. In face here is my autoload: $autoload['helper'] = array('url','asset','combine','navigation','form','portfolio','cookie','default'); This show_breadcrumbs() function is used quite a bit in some of my pages so I'm confused as to how its loading if it isn't in the autoloader. It is called like this in a few of my pages: <?=show_breadcrumbs()?> What am I missing? Why isn't this in my autoload? I even did a global search and couldn't find anywhere the helper is being loaded.

• Using JSF, PrimeFaces and JPA: Create Basic WebApp without using Generated CRUD Classes, Forms, etc

  - by user2774489

  I am trying to build a basic CRUD application with NetBeans 7.4, JSF, PrimeFaces and JPA using MySQL. I have successfully done this by using the NetBeans wizards. I want to do this from scratch, no wizards. There seems to be a lack of support for the combo of JSF, PrimeFaces and JPA. When I say "lack", I mean a full example (I might be asking too much), without using the CRUD auto-gen templates/classes AND shows actual queries coded and passed to the datatables(primefaces). YouTube is full of non-English speaking examples using Hibernate (not JPA) and other examples that show flashy GUI's with no code. So far I understand you need an @Entity class (provides the physical build of the tables), a Controller (serializable) and the .xhtml web page to show the datatable.. what else? Also, I'm not seeing any posts or examples where queries are using with JPA/JSF and how they are tied together (in one place). I need to connect the dots here so that I can leverage JSF/JPA to create simple queries to populate my PF DataTables. I've read the blogs and I've googled the intranets until I'm blue in the face. Sending me a list of URL's to read to learn about each product is something I've already done. I get what they do independently, but am looking for the "How do they all connect" answer with maybe some basic code examples!! :)

• Extracting shell script from parameterised Hudson job

  - by Jonik

  I have a parameterised Hudson job, used for some AWS deployment stuff, which in one build step runs certain shell commands. However, that script has become sufficiently complicated that I want to "extract" it from Hudson to a separate script file, so that it can easily be versioned properly. The Hudson job would then simply update from VCS and execute the external script file. My main question is about passing parameters to the script. I have a Hudson parameter named AMI_ID and a few others. The script references those params as if they were environment variables: echo "Using AMI $AMI_ID and type $TYPE" Now, this works fine inside Hudson, but not if Hudson calls an external script. Could I somehow make Hudson set the params as environment variables so that I don't need to change the script? Or is my best option to alter the script to take command line parameters (and possibly assign those to named variables for readability: ami_id=$1; type=$2; ... )? I tried something like this but the script doesn't get correctly replaced values: export AMI_ID=$AMI_ID export TYPE=$TYPE external-script.sh # this tries to use e.g. $AMI_ID Bonus question: when the script is inside Hudson, the "console output" will contain both the executed commands and their output. This is extremely useful for debugging when something goes wrong with a build! For example, here the line starting with "+" is part of the script and the following line its output: + ec2-associate-address -K pk.pem -C cert.pem 77.125.116.139 -i i-aa3487fd ADDRESS 77.125.116.139 i-aa3487fd When calling an external script, Hudson output will only contain the latter line, making debugging harder. I could cat the script file to stdout before running it, but that's not optimal either. In effect, I'd like a kind of DOS-style "echo on" for the script which I'm calling from Hudson - anyone know a trick to achieve this?

• perfmon reporting higher IOPs than possible?

  - by BlueToast

  We created a monitoring report for IOPs on performance counters using Disk reads/sec and Disk writes/sec on four servers (physical boxes, no virtualization) that have 4x 15k 146GB SAS drives in RAID10 per server, set to check and record data every 1 second, and logged for 24 hours before stopping reports. These are the results we got: Server1 Maximum disk reads/sec: 4249.437 Maximum disk writes/sec: 4178.946 Server2 Maximum disk reads/sec: 2550.140 Maximum disk writes/sec: 5177.821 Server3 Maximum disk reads/sec: 1903.300 Maximum disk writes/sec: 5299.036 Server4 Maximum disk reads/sec: 8453.572 Maximum disk writes/sec: 11584.653 The average disk reads and writes per second were generally low. I.e. for one particular server it was like average 33 writes/sec, but when monitoring in real-time it would often spike up to several hundreds and also sometimes into the thousands. Could someone explain to me why these numbers are significantly higher than theoretical calculations assuming each drive can do 180 IOPs? Additional details (RAID card): HP Smart Array P410i, Total cache size of 1GB, Write cache is disabled, Array accelerator cache ratio is 25% read and 75% write

• Question about Reporting and Data Warehousing Software bundled with SQL Server 2005

  - by anonymous user

  We currently use SQL Server 2005 Enterprise for our fairly large application, that has its roots in pre SQL Server 7.0. The tables are normalized and designed mainly for the application. The developers for the most part have the legacy SQL Server mindset. Only using the part of TSQL that existed back in 7.0, not using any of the new features of tsql or that are bundled with 2005. We're currently trying to build on demand reports using some crappy third party software, and will eventually try to build a data warehouse using more of the same crappy third party software (name removed to protect the guilty, don't ask I will not tell). The rationale for this was that we didn't want to spend more money to buy this additional software from Microsoft (this was not my decision, I had no input, but is my problem now). But from what I can tell is that Enterprise includes all of these tools, or am I missing something? What comes bundled with SQL Server 2005 Enterprise as far as reporting and data warehousing? Will we need to purchase anything else? is there actually anything else that can be purchased from Microsoft in this regard?

• Commercial NAS RAID1 disks moved to Software Raid system?

  - by Rolnik

  I've got a couple of commercial NAS boxes and I'm wondering if they (ReadyNas duo, DLink DNS-323) or any other NAS is suitable for having their RAIDed disks moved to a software-based NAS. To be specific, I'm a big fan of the (largely) Debian-based Ubuntu. Can the aforementioned NAS drives be migrated to Ubuntu (e.g. using the mdadm Linux command)? Secondly, is there any commercial NAS that can be migrated over? Incidentally, here is a link to somebody who succeeded in a migration: http://www.linuxquestions.org/questions/slackware-14/moving-raid1-drives-into-computer-with-same-md-numbers-862312/ My specific scenario I'd like to prepare for, is the eventual (sudden) death of one of the NAS motherboards.

• java annotations - problem with calling a locator class from a Vaadin Project

  - by George

  Hello, I'm not sure how to explain this without writing several pages so I hope the actual code is more expressive. I've made a jar containing multiple annotation declaration similar to the following: @Target(ElementType.PACKAGE) @Retention(RetentionPolicy.RUNTIME) public @interface MarkedPackage { } then I have made a test jar containing several classes in several packages and marked just one package with the above annotation (with package-info.java) like below: @myPackage.MarkedPackage package package.test.jar; this jar had in its build path the jar containing the annotations. then I made a static class that has a method (LoadPlugins) that retrieves a list with all the jars of a directory. Then it searches through the jars for the 'package-info' class and checks if that classes package contains the MarkedPackage annotation. by calling this: if (checkPackageAnnotation(thisClass.getPackage())) where thisClass is the package-info class retrieved via a classloader. and: public static boolean checkPackageAnnotation(AnnotatedElement elem) { System.out.println(elem.getAnnotations().length); if (elem == null || !elem.isAnnotationPresent(MarkedPackage.class)) return false; return true; } the elem.getAnnotatios().length is there for debug purposes. And the problem appears when I call the method from the static class: if I call it from a main function: public class MyMain { public static void main(String[] args){ PluginUtils.LoadPlugins(); } } everything works perfectly it displays '1' from that System.out.println(elem.getAnnotations().length); But if I call it from a button from my Vaadin project: header.addComponent(new Button("CallThat", new Button.ClickListener() { public void buttonClick(ClickEvent event) { PluginUtils.LoadPlugins(); } })); It displays '0' from that System.out.println(elem.getAnnotations().length); Also I should mention that I created the main inside my Vaadin project so it would have the exact same build path and resources. Is there a problem with web applications and that "@Retention(RetentionPolicy.RUNTIME)" ? hope I was clear enough... Hope someone has a solution for me... If you need more information - let me know. Thank you.

• Finding Common Byte Sequences in MS SQL TEXT Column

  - by regex

  Hello All, Short Desc: I'm curious to see if I can use SQL Analysis services or some other MS SQL service to mine some data for me that will show commonalities between SQL TEXT fields in a dataset. Long Desc I am looking at a subset of data that consists of about 10,000 rows of TEXT blobs which are used as a notes column in a issue tracking (ticketing) software. I would like to use something out of the box (without having to build something) that might be able to parse through all of the rows and find commonly used byte sequences in the "Notes" column. In other words, I want to find commonly used phrases (two to three word phrases, so 9 - 20 character sections of the TEXT blob). This will help me better determine if associate's notes contain similar phrases (troubleshooting techniques) that we could standardize in our troubleshooting process flow. Closing Note I'd really rather not build an application to do this as my method will probably not be the most efficient way to do it. Hopefully all this makes sense. Please let me know in the comments if anything needs clarification. Thanks in advance for your help.

• Undeliverable messages to newly migrated Exchange user

  - by johnnyb10

  We are in the process of migrating from our old domain to a new one, part of which involves migrating mailboxes from Exchange 2003 to Exchange 2007. A bunch of users have been migrated already without problems. However, one of the users is having trouble receiving emails from others. When someone sends to him, they get an Undeliverable NDR that says "A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients." The message shows the user's distinguished name as /OU=OurDomain/CN=Recipients/CN=USER57137172. The user's account name should just be "USER", so I don't know where the extra numbers ("57137172") are coming from. Thanks in advance.

• Word characteristics tags

  - by theBlinker

  I want to do a riddle AI chatbot for my AI class. So i figgured the input to the chatbot would be : Something like : "It is blue, and it is up, but it is not the ceiling" Translation : <Object X> <blue> <up> <!ceiling> </Object X> (Answer : sky?) So Input is a set of characteristics (existing \ not existing in the object), output is a matched, most likely object. The domain will be limited to a number of objects, i could input all attributes myself, but i was thinking : How could I programatically build a database of characteristics for a word? Is there such a database available? How could i tag a word, how could i programatically find all it's attributes? I was thinking on crawling wikipedia, or some forum, but i can't see it build any reliable word tag database. Any ideas on how i could achieve such a thing? Any ideas on some literature on the subject? Thank you

• CM and Agile validation process of merging to the Trunk?

  - by LoneCM

  Hello All, We are a new Agile shop and we are encountering an issue that I hope others have seen. In our process, the Trunk is considered an integration branch; it does not have to be releasable, but it does have to be stable and functional for others to branch off of. We create Feature branches of the Trunk for new development. All work and testing occurs in these branches. An individual branch pulls up as needed to stay integrated with the Trunk as other features that are accepted and are committed. But now we have numerous feature branches. Each are focused, have a short life cycle, and are pushed to the trunk as they are completed, so we not debating the need for the branches and trying very much to be Agile. My issue comes in here: I require that the branches pull up from the Trunk at the end of their life cycle and complete the validation, regression testing and handle all configuration issues before pushing to the trunk. Once reintegrated into the Trunk, I ask for at least a build and an automated smoke test. However, I am now getting push back on the Trunk validation. The argument is that the developers can merge the code and not need the QA validation steps because they already complete the work in the feature branch. Therefore, the extra testing is not needed. I have attempted to remind management of the numerous times "brainless" merges have failed. Thier solution is to instead of build and regression testing to have the developer diff the Feature branch and the newly merged Trunk. That process in thier mind would replace the regression testing I asked for. So what do you require when you reintegrate back to the Trunk? What are the issues that we will encounter if we remove this step and replace with the diff? Is the cost of staying Agile the additional work of the intergration of the branches? Thanks for any input. LoneCM

• OO vs Simplicity when it comes to user interaction

  - by Oetzi

  Firstly, sorry if this question is rather vague but it's something I'd really like an answer to. As a project over summer while I have some downtime from Uni I am going to build a monopoly game. This question is more about the general idea of the problem however, rather than the specific task I'm trying to carry out. I decided to build this with a bottom up approach, creating just movement around a forty space board and then moving on to interaction with spaces. I realised that I was quite unsure of the best way of proceeding with this and I am torn between two design ideas: Giving every space its own object, all sub-classes of a Space object so the interaction can be defined by the space object itself. I could do this by implementing different land() methods for each type of space. Only giving the Properties and Utilities (as each property has unique features) objects and creating methods for dealing with the buying/renting etc in the main class of the program (or Board as I'm calling it). Spaces like go and super tax could be implemented by a small set of conditionals checking to see if player is on a special space. Option 1 is obviously the OO (and I feel the correct) way of doing things but I'd like to only have to handle user interaction from the programs main class. In other words, I don't want the space objects to be interacting with the player. Why? Errr. A lot of the coding I've done thus far has had this simplicity but I'm not sure if this is a pipe dream or not for larger projects. Should I really be handling user interaction in an entirely separate class? As you can see I am quite confused about this situation. Is there some way round this? And, does anyone have any advice on practical OO design that could help in general?

I saw m2eclipse is being merged into Eclipse 3.7, and maven-eclipse-plugin won't be maintained any longer, so I'm looking for a m2eclipse-based solution (without running "mvn eclipse:clean eclipse:eclipse" before project import, which is what maven-eclipse-plugin does). maven-eclipse-plugin allows this in pom.xml <additionalConfig> <file> <name>.settings/com.google.gdt.eclipse.core.prefs</name> <content><![CDATA[ eclipse.preferences.version=2 jarsExcludedFromWebInfLib= warSrcDir=${project.build.directory}/${project.build.finalName} warSrcDirIsOutput=true ]]> </content> </file> The more general question is How would m2eclipse do something similar? For some cases, just saving the eclipse .settings/prefs file works (e.g. org.eclipse.jdt.ui.prefs), but in this case, com.google.gdt.eclipse.core.prefs is always overwritten on m2eclipse project import. A specific question is asked here, with no reply. Thanks! UPDATE: Not possible now, see request

• Less reboots on Windows Server Core, is this true or just a myth?

  - by Peter Hahndorf

  Because there are less components installed on a Windows Server core OS, it needs less patches than the full OS. I read in several places that therefor it needs less reboots after patching. I'm running Server 2012 core in production since September 2012 now and I don't remember a single patch-Tuesday when I did not have to reboot the server after installing Windows updates. Are there any hard numbers out there that compare the required reboots for core vs. Full OS? Less reboots may be the main reason why people choose to go with Server core. If it actually requires just as many reboots as the full OS install, they may think again the next time they set up a server.

• Conditional formatting

  - by djerry

  I have a rather annoying format I need to implement. There are 2 cells, both containing a date (cell A and B). B contains a date (24-06-2011). Cell B should be colored if cell A is between a date range, based on cell B. So if cell A lies between cell B - 7 days and cell B - 11 days, then it should be triggered. So with numbers: If B is 24-06-2011 then the range (which is not in any cell in the spreadsheet) is 13-06-2011 until 17-06-2011. If the date in cell A (let's say 14-06-2011) is in that range, cell B should be colored. Any ideas?
