  • Is it possible to store controls(Panel) as object, serialize it and store it as a file?

    - by ikky
    The topic says it all. Using Compact Framework C# I'm tiling (order/sequence is important) some images that i download from an url, into a Panel(each image is a PictureBox). This can be a huge process, and may take some time. Therefor i only want the user to download the images and tile them once. So the next time the user uses the Tile Application, the Panel that was created the first time is already stored in a file and is loaded from that file. So what i want is a method to store a Panel as a file. Is this possible, or do you think i should do it another way? I've tried something like this: BinaryWriter panelStorage = new BinaryWriter(new FileStream("imagePanel.panel", FileMode.OpenOrCreate, FileAccess.Write, FileShare.None)); Byte[] bImageObject = new Byte[20000]; bImageObject = (byte[])(object)this.imagePanel; panelStorage .Write(bMapObject); panelStorage .Close(); But the casting was not very legal :P "InvalidCastException" Can anyone help me with this problem? Thank you in advance!

  • SSIS - How do I use a resultset as input in a SQL task and get data types right?

    - by thursdaysgeek
    I am trying to merge records from an Oracle database table to my local SQL table. I have a variable for the package that is an Object, called OWell. I have a data flow task that gets the Oracle data as a SQL statment (select well_id, well_name from OWell order by Well_ID), and then a conversion task to convert well_id from a DT_STR of length 15 to a DT_WSTR; and convert well_name from a DT_STR of length 15 to DT_WSTR of length 50. That is then stored in the recordset OWell. The reason for the conversions is the table that I want to add records to has an identity field: SSIS shows well_id as a DT_WSTR of length 15, well_name a DT_WSTR of length 50. I then have a SQL task that connects to the local database and attempts to add records that are not there yet. I've tried various things: using the OWell as a result set and referring to it in my SQL statement. Currently, I have the ResultSet set to None, and the following SQL statment: Insert into WELL (WELL_ID, WELL_NAME) Select OWELL_ID, OWELL_NAME from OWell where OWELL_ID not in (select WELL.WELL_ID from WELL) For Parameter Mapping, I have Paramater 0, called OWell_ID, from my variable User::OWell. Parameter 1, called OWell_Name is from the same variable. Both are set to VARCHAR, although I've also tried NVARCHAR. I do not have a Result set. I am getting the following error: Error: 0xC002F210 at Insert records to FLEDG, Execute SQL Task: Executing the query "Insert into WELL (WELL_ID, WELL_NAME) Select OWELL..." failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_STR)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. I don't think it's a data type issue, but rather that I somehow am not using the resultset properly. How, exactly, am I supposed to refer to that recordset in my SQL task, so that I can use the two recordset fields and add records that are missing?

  • Re-Convert timestamp DATE back to original format (when editing) PHP MySQL

    - by Jess
    Ok so I have managed to get the format of the date presented in HTML (upon display) to how I want (dd/mm/yyy)...However, the user also can change the date via a form. So this is how it's setup as present. Firstly, the conversion from YYYY-MM-DD to DD/MM/YYYY and then display in HTML: $timestamp = strtotime($duedate); echo date('d/m/Y', $timestamp); Now when the user selects to update the due date, the value already stored value is drawn up and presented in my text field (using exactly the same code as above).. All good so far. But when my user runs the update script (clicks submit), the new due date is not being stored, and in my DB its seen as '0000-00-00'. I know I need to convert it back to the correct format that MySQL wants to have it in, in order for it to be saved, but I'm not sure on how to do this. This is what I have so far in my update script (for the due date): $duedate = $_POST['duedate']; $timestamp = strtotime($duedate); date('Y/m/d', $timestamp); $query = "UPDATE films SET filmname= '".$filmname."', duedate= '".$duedate; Can somebody please point me in the right direction to have the new date, when processed, converted back to the accepted format by MySQL. I appreciate any help given! Thanks.

  • c# webbrowser | pushed realtime quotes

    - by Eric
    Hi, I am programmer and share trader. Before I have written a day trading application. Until last week it was possible to fetch realtime quotes from http://aktien.boerse.de/aktien_startseite.php?view=2&order=name%20asc&liste=prime&page=0 . Every time the site was surfed the quotes had changed. The HTML contents could then be decoded with regular expressions (regex). Problem They have stopped this service by today. Now the quotes are not realtime when surfing on the page. The only way to get stock quotes now is to use pushed quotes "Push starten"-Button. However I do not know how to basically fetch them in C#. When I create a webbrowser element the only way which I know to get the push quotes out of it is to give the webbrowser element the focus send key ctrl+A and ctrl+C and insert the data some where for decoding. This is not desired since the control is moved away from the user and in case some other control is clicked during the process this may result in unexpected behaviour. Question So is there a proper way to decode push stock quotes in C#? Thanks a lot in advance, --eric

  • Is there a programming toolkit for converting "any file type" to a TIFF image?

    - by Ryan
    Hello, I've written several variations of a program. The purpose of the program is to convert "any file type" to a TIFF image represenation of that file, as if it were being printed using a printer. I'm currently using a third party printer driver that I send files to, and it outputs a TIFF image. This is nice, but it requires me to use Office Interop files, and interact with each individual processing application in order to print the files. I had previously tried a toolkit, called Apose .NET, which did not rely on Office Interop, and did not require any printer driver. It did the conversion all on its own and would create a TIFF image. The problem with Aspose .NET was that it did not support a wide variety of input file types. Most notably, it can't do Visio files. My project calls for the ability to create a TIFF image for virtually "any file type". (excluding exes, music files, and stuff) I know that finding something that handles literally any file type is probably not a very feasible task, so I figure if it can at least handle all the Office file types, Adobe types, and other major standard file types, then I can write a custom extension parsing module that uses those processing applications to do the printing of any file type that can be viewed using those applications. So, does anyone know of a toolkit that can do this? Preferably one that does not rely on Office or a printer driver. It does not have to be free, or open source. Or, if you know of an amazing printer driver that does this, I'm open to that too. Thanks in advance, Ryan

  • F#: Tell me what I'm missing about using Async.Parallel

    - by JBristow
    ok, so I'm doing ProjectEuler Problem #14, and I'm fiddling around with optimizations in order to feel f# out. in the following code: let evenrule n = n / 2L let oddrule n = 3L * n + 1L let applyRule n = if n % 2L = 0L then evenrule n else oddrule n let runRules n = let rec loop a final = if a = 1L then final else loop (applyRule a) (final + 1L) n, loop (int64 n) 1L let testlist = seq {for i in 3 .. 2 .. 1000000 do yield i } let getAns sq = sq |> Seq.head let seqfil (a,acc) (b,curr) = if acc = curr then (a,acc) else if acc < curr then (b,curr) else (a,acc) let pmap f l = seq { for a in l do yield async {return f a} } |> Seq.map Async.RunSynchronously let pmap2 f l = seq { for a in l do yield async {return f a} } |> Async.Parallel |> Async.RunSynchronously let procseq f l = l |> f runRules |> Seq.reduce seqfil |> fst let timer = System.Diagnostics.Stopwatch() timer.Start() let ans1 = testlist |> procseq Seq.map // 837799 00:00:08.6251990 printfn "%A\t%A" ans1 timer.Elapsed timer.Reset() timer.Start() let ans2 = testlist |> procseq pmap printfn "%A\t%A" ans2 timer.Elapsed // 837799 00:00:12.3010250 timer.Reset() timer.Start() let ans3 = testlist |> procseq pmap2 printfn "%A\t%A" ans3 timer.Elapsed // 837799 00:00:58.2413990 timer.Reset() Why does the Async.Parallel code run REALLY slow in comparison to the straight up map? I know I shouldn't see that much of an effect, since I'm only on a dual core mac. Please note that I do NOT want help solving problem #14, I just want to know what's up with my parallel code.

    Hello there, Basically i got this for loop and i want the number inputed (eg. 123) to be printed out in reverse, so "321". so far it works fine and prints out the correct order when the for loop is for(i = 0; i<len ; i++) but i get an error when i try to print it in reverse?. Whats going wrong? #include <stdio.h> #include <string.h> void cnvrter(char *number); int main(){ char number[80]; printf("enter a number "); gets(number); cnvrter(number); return 0; } void cnvrter(char *number){ char tmp[80]; int i = 0,len = 0; int cnvrtd_digit = 0; len = strlen(number); printf("\nsize of input %d\n",len); for(i = len; i>len ; i--){ if ( ( number[i] >= '0' ) && ( number[i]<='9' ) ){ tmp[0] = number[i]; sscanf(tmp,"%d",&cnvrtd_digit); } printf("%d\n",cnvrtd_digit); } }

  • How can I edit an exe's resources (File Description, Icon, etc.) using a command line utility?

    - by Coder7862396
    The whole story: I have created a fancy .NET program which has an installer created by the Visual Studio Installer (VSI). The VSI creates 2 files (setup.exe and MyProgramSetup.msi). I understand the reasons for both files being needed, however, I only want to distribute a SINGLE executable installer to users. I do not want them to see 2 files and have to choose between them. In order to do this I have merged the 2 files into a self-extracting archive using IExpress (as seen in this answer: http://stackoverflow.com/questions/535966/merge-msi-and-exe). This works well, however, the self-extracting archive that gets created has an ugly icon and confusing file info (the File Description is "Win32 Cabinet Self-Extractor" with 43 black spaces after it). I need to replace the icon with my custom one and change some of the file properties like "Description", "Company", etc. I would like to have this automatically done as a build step so having a program which is a command line/console utility would be great. I've searched for a while now and can only find one program which does exactly what I want (ResourceTuner Console: http://www.heaventools.com/command-line_resource_editor.htm) but it costs an arm and a leg and my budget is $0. Does anyone know a better way to achieve what I want, or know of a program which can replace an executable's resources without having to use a GUI? By the way, I have also tried "SiComponents Resource Builder 3" which can't even open the executable, and "Julien Audo's ResEdit" which just crashes when I execute the command: "resedit.exe -convert "Modified Resources.rc" "MyProgramSetup.exe"

  • Aren't Information Expert / Tell Don't Ask at odds with Single Responsibility Principle?

    - by moffdub
    It is probably just me, which is why I'm asking the question. Information Expert, Tell Don't Ask, and SRP are often mentioned together as best practices. But I think they are at odds. Here is what I'm talking about: Code that favors SRP but violates Tell Don't Ask, Info Expert: Customer bob = ...; // TransferObjectFactory has to use Customer's accessors to do its work, // violates Tell Don't Ask CustomerDTO dto = TransferObjectFactory.createFrom(bob); Code that favors Tell Don't Ask / Info Expert but violates SRP: Customer bob = ...; // Now Customer is doing more than just representing the domain concept of Customer, // violates SRP CustomerDTO dto = bob.toDTO(); If they are indeed at odds, that's a vindication of my OCD. Otherwise, please fill me in on how these practices can co-exist peacefully. Thank you. Edit: someone wants a definition of the terms - Information Expert: objects that have the data needed for the operation should host the operation Tell Don't Ask: don't ask objects for data in order to do work; tell the objects to do the work Single Responsibility Principle: each object should have a narrowly defined responsibility

  • applicationWillTerminate Appears to be Inconsistent

    - by Lauren Quantrell
    This one has me batty. In applicationWillTerminate I am doing two things: saving some settings to the app settings plist file and updating any changed data to the SQLite database referenced in the managedObjectContext. Problem is it works sometimes and not others. Same issue in the simulator and on the device. If I hit the home button while the app is running, I can only sometimes get the data to store in the plist and into the CoreData store. It seems that it's both works or neither works, and it makes no difference if I switch the execution order (saveState, managedObjectContext or managedObjectContext, saveState). I can't figure out how this can happen. Any help is greatly appreciated. lq AppDelegate.m @synthesize rootViewController; - (void)applicationWillTerminate:(UIApplication *)application { [rootViewController saveState]; NSError *error; if (managedObjectContext != nil) { if ([managedObjectContext hasChanges] && ![managedObjectContext save:&error]) { // Handle error exit(-1); // Fail } } } RootViewController.m - (void)saveState { NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setInteger:self.someInteger forKey:kSomeNumber]; [userDefaults setObject:self.someArray forKey:kSomeArray]; }

  • Comparing two date ranges within the same table

    - by Danny Herran
    I have a table with sales per store as follows: SQL> select * from sales; ID ID_STORE DATE TOTAL ---------- -------- ---------- -------------------------------------------------- 1 1 2010-01-01 500.00 2 1 2010-01-02 185.00 3 1 2010-01-03 135.00 4 1 2009-01-01 165.00 5 1 2009-01-02 175.00 6 5 2010-01-01 130.00 7 5 2010-01-02 135.00 8 5 2010-01-03 130.00 9 6 2010-01-01 100.00 10 6 2010-01-02 12.00 11 6 2010-01-03 85.00 12 6 2009-01-01 135.00 13 6 2009-01-02 400.00 14 6 2009-01-07 21.00 15 6 2009-01-08 45.00 16 8 2009-01-09 123.00 17 8 2009-01-10 581.00 17 rows selected. What I need to do is to compare two date ranges within that table. Lets say I need to know the differences in sales between 01 Jan 2009 to 10 Jan 2009 AGAINST 01 Jan 2010 to 10 Jan 2010. I'd like to build a query that returns something like this: ID_STORE_A DATE_A TOTAL_A ID_STORE_B DATE_B TOTAL_B ---------- ---------- --------- ---------- ---------- ------------------- 1 2010-01-01 500.00 1 2009-01-01 165.00 1 2010-01-02 185.00 1 2009-01-02 175.00 1 2010-01-03 135.00 1 NULL NULL 5 2010-01-01 130.00 5 NULL NULL 5 2010-01-02 135.00 5 NULL NULL 5 2010-01-03 130.00 5 NULL NULL 6 2010-01-01 100.00 6 2009-01-01 135.00 6 2010-01-02 12.00 6 2009-01-02 400.00 6 2010-01-03 85.00 6 NULL NULL 6 NULL NULL 6 2009-01-07 21.00 6 NULL NULL 6 2009-01-08 45.00 6 NULL NULL 8 2009-01-09 123.00 6 NULL NULL 8 2009-01-10 581.00 So, even if there are no sales in one range or another, it should just fill the empty space with NULL. So far, I've come up with this quick query, but I the "dates" from sales to sales2 sometimes are different in each row: SELECT sales.*, sales2.* FROM sales LEFT JOIN sales AS sales2 ON (sales.id_store=sales2.id_store) WHERE sales.date >= '2010-01-01' AND sales.date <= '2010-01-10' AND sales2.date >= '2009-01-01' AND sales2.date <= '2009-01-10' ORDER BY sales.id_store ASC, sales.date ASC, sales2.date ASC What am I missing?

  • Output iterator's value_type

    - by wilhelmtell
    The STL commonly defines an output iterator like so: template<class Cont> class insert_iterator : public iterator<output_iterator_tag,void,void,void,void> { // ... Why do output iterators define value_type as void? It would be useful for an algorithm to know what type of value it is supposed to output. For example, a function that translates a URL query "key1=value1&key2=value2&key3=value3" into any container that holds key-value strings elements. template<typename Ch,typename Tr,typename Out> void parse(const std::basic_string<Ch,Tr>& str, Out result) { std::basic_string<Ch,Tr> key, value; // loop over str, parse into p ... *result = typename iterator_traits<Out>::value_type(key, value); } The SGI reference page of value_type hints this is because it's not possible to dereference an output iterator. But that's not the only use of value_type: I might want to instantiate one in order to assign it to the iterator.

  • Error 1053: the service did not respond to the start or control request in a timely fashion

    - by deejjaayy
    i know this is very much a "how long is a piece of string" type of question, however i have recently inherited a couple of applications that run as windows services, and i am having problems providing a gui (accessible from a context menu in system tray) with both of them. before you ask, the reason why we need a gui for a windows service is in order to be able to re-configure the behaviour of the windows service(s) without resorting to stopping/re-starting. my code works fine in debug mode, and i get the context menu come up, and everything behaves correctly etc. when i install the service via "installutil" using a named account (i.e., not Local System Account), the service runs fine, but doesn't display the icon in the system tray (i know this is normal behaviour because i don't have the "interact with desktop" option). here is the problem though - when i choose the "LocalSystemAccount" option, and check the "interact with desktop" option, the service takes AGES to start up for no obvious reason, and i just keep getting "Could not start the ... service on Local Computer. Error 1053: the service did not respond to the start or control request in a timely fashion". incidentally, i increased the windows service timeout from the default 30 seconds to 2 minutes via a registry hack (see http://support.microsoft.com/kb/824344, search for TimeoutPeriod in section 3), however the service start up still times out. my first question is - why might the "Local System Account" login takes SOOOOO MUCH LONGER than when the service logs in with the non-LocalSystemAccount, causing the windows service time-out? what's could the difference be between these two to cause such different behaviour at start up? secondly - taking a step back, all i'm trying to achieve, is simply a windows service that provides a gui for configuration - I'd be quite happy to run using the non-Local System Account (with named user/pwd), if I could get the service to interact with the desktop (that is, have a context menu available from the system tray). is this possible, and if so how? any pointers to the above questions would be very much appreciated! thanks in advance for your help.

In order to avoid annoying dialogues I wanted to load JOAL with the JNLPAppletLauncher as it is shown on https://jogl-demos.dev.java.net/applettest-joal.html Unfortunately with this approach I get this exception: JNLPAppletLauncher.loadLibrary("joal_native") loading: C:\Users\Barbara\AppData\Local\Temp\jnlp-applet\jln7379734545861869319\jln1640167325490042232\joal_native.dll Exception in thread "AWT-EventQueue-2" java.lang.RuntimeException: Can not get proc address for method "alcCaptureCloseDevice": Couldn't set value of field "_addressof_alcCaptureCloseDevice" in class net.java.games.joal.impl.ALCProcAddressTable at com.sun.gluegen.runtime.ProcAddressHelper.resetProcAddressTable(ProcAddressHelper.java:113) at net.java.games.joal.impl.ALProcAddressLookup.resetALCProcAddressTable(ALProcAddressLookup.java:109) at net.java.games.joal.impl.ALCImpl.alcOpenDevice(ALCImpl.java:341) at net.java.games.joal.util.ALut.alutInit(ALut.java:69) at demos.devmaster.lesson1.SingleStaticSource.initialize(SingleStaticSource.java:194) at demos.devmaster.lesson1.SingleStaticSource.access$000(SingleStaticSource.java:57) at demos.devmaster.lesson1.SingleStaticSource$1.actionPerformed(SingleStaticSource.java:79) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) Caused by: java.lang.RuntimeException: Unable to find and load OpenAL library at net.java.games.joal.impl.ALProcAddressLookup$DynamicLookup.dynamicLookupFunction(ALProcAddressLookup.java:66) at com.sun.gluegen.runtime.ProcAddressHelper.resetProcAddressTable(ProcAddressHelper.java:106) ... 30 more I am using Firefox 3.6.3, Java 1.6._017 and am on a Windows 7 Machine. I also tried this on another computer with Windows XP and on one with Linux, always with the same result, so it does not seem to be specific for my computer. I also get the same result for IE8. Any ideas how I could fix this? Thank you very much.

  • Using Moq callbacks correctly according to AAA

    - by Hadi Eskandari
    I've created a unit test that tests interactions on my ViewModel class in a Silverlight application. To be able to do this test, I'm mocking the service interface, injected to the ViewModel. I'm using Moq framework to do the mocking. to be able to verify bounded object in the ViewModel is converted properly, I've used a callback: [Test] public void SaveProposal_Will_Map_Proposal_To_WebService_Parameter() { var vm = CreateNewCampaignViewModel(); var proposal = CreateNewProposal(1, "New Proposal"); Services.Setup(x => x.SaveProposalAsync(It.IsAny<saveProposalParam>())).Callback((saveProposalParam p) => { Assert.That(p.plainProposal, Is.Not.Null); Assert.That(p.plainProposal.POrderItem.orderItemId, Is.EqualTo(1)); Assert.That(p.plainProposal.POrderItem.orderName, Is.EqualTo("New Proposal")); }); proposal.State = ObjectStates.Added; vm.CurrentProposal = proposal; vm.Save(); } It is working fine, but if you've noticed, using this mechanism the Assert and Act part of the unit test have switched their parts (Assert comes before Acting). Is there a better way to do this, while preserving correct AAA order?

  • Suckerfish Menu Not Working. Nested UL not displaying block

    - by Brett
    I'm going out of my mind with this one. I'm trying to build a suckerfish css drop down menu. I have the first level working ok but I can't get the nested ul (under the Glossary tab) to display in block format and show my a background color. I've been at this for three days and I'm about to go crazy. If anyone can help I'd really appreciate it. You can see it here: www.brettlockhart.com/blast/ body { min-width:640px; margin:0px; padding:0px 40px 0px 40px; background-color:#eee; } /*Nav One styles*/ nav#navOne ul { width:100%; min-width:640px; height:25px; margin:0px auto; padding:0px; background-image:url(/blast/images/navOneBg.png); border-radius:0px 0px 8px 8px; text-align:right; float:right; } nav#navOne ul li { position:relative; display:inline; margin: 0px 0px 0px 10px auto; padding:3px 0px; border-left:1px #0b4c8f solid; line-height:23px; } nav#navOne ul li:last-child { margin-right:10px; } .arrowDown { margin: auto; font-family:Tahoma, Geneva, sans-serif; font-size:.7em; color:#FFF; padding: 0px 5px 0px 0px; } nav#navOne ul li a { margin: 0px auto; padding: 4px 10px 4px 15px; font-family:Tahoma, Geneva, sans-serif; font-size:.7em; color:#FFF; border-left:1px #5d9ee0 solid; text-decoration:none; line-height:23px; } /*Nav One rollover*/ nav#navOne ul li ul { display:none; background-image:none; } nav#navOne ul li:hover ul { display:block !important; } nav#navOne ul li:hover nav#navOne ul li ul li { background-color:#69C !important; left:0px; top:26px; z-index:10; } h1 { float:left; width:158px; text-indent:-9999px; background-image:url(/blast/images/logo.png); background-repeat:no-repeat; } #search { float:right; width:280px; margin:0px; padding:0px; } /*Nav Two styles*/ nav#navTwo h3 { display:inline; } nav#navTwo ul { width:100%; height:50px; margin:0 auto; padding:0px; border:1px solid red; clear:both; } nav#navTwo ul li { display:inline; border: 1px solid green; margin-top:20px; } <header> <nav id="navOne"> <ul> <li><a href="#">Sign In</a></li> <li><a href="#">Register</a></li> <li><a href="#">Print Page</a></li> <li id="glossary"><a href="#">Glossary</a> <ul> <li><a href="#">Item Placeholder</a></li> <li><a href="#">Item Placeholder</a></li> <li><a href="#">Item Placeholder</a></li> <li><a href="#">Item Placeholder</a></li> <li><a href="#">Item Placeholder</a></li> <li><a href="#">Item Placeholder</a></li> </ul> </li> <li><a href="#">Text Size: A A A</a></li> <li><a href="#">Select Your Location</a> <span class="arrowDown">&#x2C5;</span></li> </ul> </nav><!--/navOne--> <h1>Logo</h1> <div id="search"> <form action="?" method="get"> <fieldset> <input type="text" id="searchField"> <input type="submit" id="searchSubmit" value="Submit"> Search:<label for="radioHere">here</label> <input type="radio" id="radioHere" name="here" value="here"> <label for="radioWeb">the web</label> <input type="radio" id="radioWeb" name="the web" value="the web"> </fieldset> </form> </div><!--/search--> <nav id="navTwo"> <ul> <li><h3>Residential:</h3></li> <li>TV</li> <li>Internet</li> <li>Phone</li> <li>Pricing</li> <li class="navTwoSelected">Music</li> <li>Order</li> <li>Billing</li> <li>Support</li> <li>|</li> <li>Business</li> <li>About Us</li> </ul> </nav><!--/navTwo--> <nav id="navThree"> <ul> <li>Today</li> <li>Watch</li> <li>Surf</li> <li>Play</li> <li class="navThreeSelected">Listen</li> <li>Learn</li> <li>Local</li> </ul> <h3>Tools:</h3> <ul> <li>Webmail</li> <li>Account</li> <li>Billing</li> <li>Order Services</li> </ul> </nav><!--/navThree--> <nav id="navFour"> <h3>Your are here:</h3> <ul id="breadcrumbs"> <li>Residential ></li> <li>My Place ></li> <li>Listen ></li> <li class="currentPage">Music</li> </ul> </nav><!--/navFour--> </header>

  • kick off a map reduce job from my java/mysql webapp

    - by Brian
    Hi guys, I need a bit of archecture advice. I have a java based webapp, with a JPA based ORM backed onto a mysql relational database. Now, as part of the application I have a batch job that compares thousands of database records with each other. This job has become too time consuming and needs to be parallelized. I'm looking at using mapreduce and hadoop in order to do this. However, I'm not too sure about how to integrate this into my current architecture. I think the easiest initial solution is to find a way to push data from mysql into hadoop jobs. I have done some initial research on this and found the following relevant information and possibilities: 1) https://issues.apache.org/jira/browse/HADOOP-2536 this gives an interesting overview of some inbuilt JDBC support 2) This article http://architects.dzone.com/articles/tools-moving-sql-database describes some third party tools to move data from mysql to hadoop. To be honest I'm just starting out with learning about hbase and hadoop but I really don't know how to integrate this into my webapp. Any advice is greatly appreciated. cheers, Brian

  • java BufferedReader specific length returns NUL characters

    - by Bastien
    I have a TCP socket client receiving messages (data) from a server. messages are of the type length (2 bytes) + data (length bytes), delimited by STX & ETX characters. I'm using a bufferedReader to retrieve the two first bytes, decode the length, then read again from the same bufferedReader the appropriate length and put the result in a char array. most of the time, I have no problem, but SOMETIMES (1 out of thousands of messages received), when attempting to read (length) bytes from the reader, I get only part of it, the rest of my array being filled with "NUL" characters. I imagine it's because the buffer has not yet been filled. char[] bufLen = new char[2]; _bufferedReader.read(bufLen); int len = decodeLength(bufLen); char[] _rawMsg = new char[len]; _bufferedReader.read(_rawMsg); return _rawMsg; I solved the problem in several iterative ways: first I tested the last char of my array: if it wasn't ETX I would read chars from the bufferedReader one by one until I would reach ETX, then start over my regular routine. the consequence is that I would basically DROP one message. then, in order to still retrieve that message, I would find the first occurence of the NUL char in my "truncated" message, read & store additional characters one at a time until I reached ETX, and append them to my "truncated" messages, confirming length is ok. it works also, but I'm really thinking there's something I could do better, like checking if the total number of characters I need are available in the buffer before reading it, but can't find the right way to do it... any idea / pointer ? thanks !

  • cfchart ignores my scalefrom value

    - by Monte Chan
    Hi all, I have the following codes in my page. The style variable holds the custom style. <cfchart chartheight="450" chartwidth="550" gridlines="9" yaxistitle="Score" scalefrom="20" scaleto="100" style="#style#" format="png" > <cfchartseries query="variables.chart_query" type="scatter" seriescolor="##000000" itemcolumn="MyItem" valuecolumn="MyScore"/> </cfchart> Before I begin, please go to http://www.monteandjanicechan.com/chart_good.jpg. This is how I want my report to come up. On the x-axis, there will always be three items as long as at least one of them has values. If an item does not have any values (i.e. 2010), there would not be a marker in the chart. The problem occurs only when only one item has value. Please see http://www.monteandjanicechan.com/chart_bad.jpg. As you can see, 2008 and 2010 do not have any values; y-axis is now scaled from 0 to 100. I have tried setting one of the items (ex. 2008) a value of 0 or something off the chart; it would scale according to this off-the-chart value and the 2009 value. In short, I have to have at least two items with values between 20 and 100 in order for cfchart to scale from 20 to 100. My question is, how can I correct the issue so that cfchart would ALWAYS scale from 20 to 100? I am running CF9. Thanks in advance, Monte
