• An annoying printing issue with Crystal Reports 2008

  - by Xience

  A little background: I have an extremely annoying printing issue with crystal reports. My environment is crystal reports 2008 SP2 on Windows 7 (64bit), Visual studio 2008 and .net framework 3.5 with all the latest updates for everything. The report is designed basically to render a small shelf label of the size (40mm width and 20mm height). In crystal when I set the page size to the above mentioned values and set orientation to portrait and take a preview, everything is displayed as i expect it to be and issuing a print command, it prints absolutely correct. The problem: The problem comes when i print this report from my program (in vb.net), dynamically setting data to some text fields, the result is that crystal somehow changes the print orientation, NOT the paper orientation as in portrait or landscape. Instead of printing from top left towards the bottom right, it rotates the whole output at 90 degrees to the left and reduces everything so small that it is barely visible, although it prints everything out. I have tested it on Intermec PF8t and Zebra GK420d label printers and a whole bunch of laser printers, but with the above stated page settings the output is always the same. Another strange thing that i noticed while experimenting with page sizes if i switch to landscape mode, the print out is correct in its font sizes and positions but then the text gets truncated due to overflowing the page size. Can anyone help me with this. Does crystal has anything like its own print drivers or something. I have tried to ensure to the best of my abilities that it is not a printer driver problem.

• FireFox Toolbar Prefwindow unload/acceptdialog Event to Update the toolbar

  - by Mark

  Hi all, I'm trying to develop a firefox toolbar ;) so my structure is In the options.xul is an PrefWindow which i'm opening over an <toolbarbutton oncommand="esbTb_OpenPreferences()"/> function esbTb_OpenPreferences() { window.openDialog("chrome://Toolbar/content/options.xul", "einstellungen", "chrome,titlebar,toolbar,centerscreen,modal", this);} so in my preferences i can set some checkboxes which indicates what links are presented in my toolbar. So when the preferences window is Closed or the "Ok" button is hitted I want to raise an event or an function which updates via DOM my toolbar. So this is the function which is called when the toolbar is loaded. It sets the links visibility of the toolbar. function esbTB_LoadMenue() { var MenuItemNews = document.getElementById("esbTb_rss_reader"); var MenuItemEservice = document.getElementById("esbTb_estv"); if (!(prefManager.getBoolPref("extensions.esbtoolbar.ShowNews"))) { MenuItemNews.style.display = 'none'; } if (!(prefManager.getBoolPref("extensions.esbtoolbar.ShowEservice"))) { MenuItemEservice.style.display = 'none'; } } So I tried some thinks like adding an eventlistener to the dialog which doesn't work... in the way I tried... And i also tried to hand over the window object from the root window( the toolbar) as an argument of the opendialog function changed the function to this. function esbTB_LoadMenue(RootWindow) { var MenuItemNews = RootWindow.getElementById("esbTb_rss_reader"); var MenuItemEservice = RootWindow.getElementById("esbTb_estv");} And then tried to Access the elements over the handover object, but this also not changed my toolbar at runtime. So what i'm trying to do is to change the visibile links in my toolbar during the runtime and I don't get it how I should do that... thanks in advance

• Loading a javascript library in javax.script?

  - by Shane

  I want to run Protovis javascript from Java and get the evaluated SVG code. I am using javax.script.* to run the Javascript: public static void EvalScript() throws Exception { ScriptEngineManager factory = new ScriptEngineManager(); ScriptEngine engine = factory.getEngineByName("JavaScript"); Object result = engine.eval("var vis = new pv.Panel().width(300).height(300) .add (pv.Line).data ([1,0.5, 0.1, 0.01, 0.001, 0.3, 0.2,0.1,1]) .left (function () { return this.index * 30; }) .bottom (function (d) { return d * 250; }); vis.root.render(); vis.scene[0].canvas.innerHTML;"); System.out.println(result); } This would complain because I never loaded Protovis itself, as would ordinarily be done with <script type="text/javascript" src="../protovis-r3.1.0.js"></script> Is there a good way, short of sourcing in the full Javascript into the eval() command, of loading a library when running Javascript through javax.script? (Incidentally, I know of examples that use Rhino to do this from the Google discussion group.)

• SL 3 navigation not working!

  - by Silver Gun

  Hey Guys I converted all my existing Silverlight app UserControls to Pages so I could use the Navigation Framework. Anyway so I created a UserControl called MyFrame, which would host all the pages. In my App.xaml.cs I have the following to make sure that MyFrame is loaded when the App loads: private void Application_Startup(object sender, StartupEventArgs e) { this.RootVisual = new MyFrame(); } My UriMapper class resides in App.xaml and looks like the following: <navcore:UriMapper x:Key="uriMapper"> <navcore:UriMapping Uri="Login" MappedUri="Login.xaml"> </navcore:UriMapper> Within my 'MyFrame' class, I have the following <StackPanel Orientation="Horizontal"> <StackPanel Orientation="Vertical"> <HyperlinkButton Tag="Login" Content="Login" Click="HyperlinkButton_Click" /> </StackPanel> <StackPanel Orientation="Vertical"> <navigation:Frame x:Name="ContentFrame" Style="{StaticResource ContentFrameStyle}" /> </StackPanel> </StackPanel> And within the callback for my HyperlinkButton's event handler, I have the following: private void HyperlinkButton_Click(object sender, RoutedEventArgs e) { ContentFrame.Navigate(new Uri((sender as HyperlinkButton).Tag.ToString(), UriKind.Relative)); } The Login.xaml file is in my root folder (right under Project). This navigation does not seem to work! The exception I get reads like so: Navigation is only supported to relative URIs that are fragments, or begin with '/', or which contain ';component/'. Parameter name: uri The Login page does not load. There is no problem with Login.xaml as when I set this.RootVisual = new Login(); the page loads just fine. I also tried setting the NavigateUri attribute of the HyperlinkButton to "Login." No cigar. I'll appreciate any help! Thanks a lot in advance

• Using nhibernate <loader> element with HQL queries

  - by Matt

  Hi All I'm attempting to use an HQL query in element to load an entity based on other entities. My class is as follows public class ParentOnly { public ParentOnly(){} public virtual int Id { get; set; } public virtual string ParentObjectName { get; set; } } and the mapping looks like this <class name="ParentOnly"> <id name="Id"> <generator class="identity" /> </id> <property name="ParentObjectName" /> <loader query-ref="parentonly"/> </class> <query name="parentonly" > select new ParentOnly() from SimpleParentObject as spo where spo.Id = :id </query> The class that I am attemping to map on top of is SimpleParentObject, which has its own mapping and can be loaded and saved without problems. When I call session.Get(id) the sql runs correctly against the SimpleParentObject table, and the a ParentOnly object is instantiated (as I can step through the constructer), but only a null comes back, rather than the instantiated ParentOnly object. I can do this succesfully using a instead of the HQL, but am trying to build this in a database independent fashion. Any thoughts on how to get the and elements to return a populated ParentOnly object...? Thanks Matt

• How to launch multiple Internet Explorer windows/tabs from batch file?

  - by TheZenker

  I would like a batch file to launch two separate programs then have the command line window close. Actually, to clarify, I am launching Internet Explorer with two different URLs. So far I have something like this: start "~\iexplore.exe" "url1" start "~\iexplore.exe" "url2" What I get is one instance of Internet Explorer with only the second URL loaded. Seems the second is replacing the second. I seem to remember a syntax where I would load a new command line window and pass the command to execute on load, but can't find the reference. As a second part of the question: what is a good reference URL to keep for the times you need to write a quick batch file? Edit: I have marked an answer, because it does work. I now have two windows open, one for each URL. (thanks!) The funny thing is that without the /d approach using my original syntax I get different results based on whether I have a pre-existing Internet Explorer instance open. If I do I get two new tabs added for my two URLs (sweet!) If not I get only one final tab for the second URL I passed in.

• How to get all active parameters in ASP.NET MVC (2)

  - by SztupY

  Hi! I was wondering whether there is a way to create an ActionLink or similar, that changes only a few parameters of the actual query, and keeps all the other parameters intact. For example if I'm on an URL like http://example.com/Posts/Index?Page=5&OrderBy=Name&OrderDesc=True I want to change only the Page, or OrderBy parameter and keep all other parameters the same, even those I don't yet know of (like when I want to add a Search parameter or something similar too). The header of my current action looks like this: public ActionResult Index(int? Page, string OrderBy, bool? Desc) and I'm only interested in the values that this controller "eats". I want however that when I extend this action (for example with a string Search parameter) the links should work the same way as before. Here is what I did already: Create a new RouteValueDictionary and fill it with everything from RouteData.Values Problem: This only fills the parameters that are used in the Routing, so all other optional parameters (like Page) to the controller are lost Add everything from HttpContext.Request.QueryString to the previous dictionary This is what I am currently using Problem: It might have some junk stuff, that the Controller didn`t ask for, and it doesn't work if the page was loaded using POST. You also don't have any ModelBindings (but this isn't much of a problem, because we are re-sending everything anyway) Use HttpContext.Request.Params Problem: this has too much junk data which imho one shouldn't add to a RouteValueDictionary that is passed to an ActionLink So the questions: Is there an RVD that has all the data that was passed to the Controller and was used by it? Is this solution good, or are there any caveats I didn't think about (mainly in the context of changing a few query parameters while keeping the others intact)? Is there a way to filter out the "junk" data from the Params object?

• How to select form input based on label inner HTML?

  - by Shane

  I have multiple forms that are dynamically created with different input names and id's. The only thing unique they will have is the inner HTML of the label. Is it possible to select the input via the label inner HTML with jQuery? Here is an example of one of my patient date of birth blocks, there are many and all unique except for innerHTML. <div class="iphorm-element-spacer iphorm-element-spacer-text iphorm_1_8-element-spacer"> <label for="iphorm_081a9e2e6b9c83d70496906bb4671904150cf4b43c0cb1_8">events=Object { mouseover=[1], mouseout=[1]}handle=function()data=Object { InFieldLabels={...}} Patient DOB <span class="iphorm-required">*</span> </label> <div class="iphorm-input-wrap iphorm-input-wrap-text iphorm_1_8-input-wrap"> <input id="iphorm_081a9e2e6b9c83d70496906bb4671904150cf4b43c0cb1_8" class="iphorm-element-text iphorm_1_8" type="text" value="" name="iphorm_1_8">events=Object { focus=[1], blur=[1], keydown=[1], more...}handle=function() </div> <div class="iphorm-errors-wrap iphorm-hidden"> </div> This is in a Wordpress Plugin and because we are building to allow employees to edit their sites (this is actually a Wordpress Network), we do not want to alter the plugin if possible. Note that the label "for" and the input "id" share the same dynamic key, so this might be a way to maybe get the id, but wanted to see if there is a shorter way of doing this.

• how to find the height of html content

  - by ganapati hegde

  Hi, I am trying to display 10 html pages as a single document,with 10 chapters. I am using Webkitgtk+ engine to render the HTML pages. I am getting the content of each html files and concatenating all of them to create a single 'char *content' and using webkit_web_view_load_html_string(WebKitWebView *web_view, const gchar *content, const gchar *base_uri); this function to load all the HTML files, as a document. Now i am trying to build a 'table of contents(toc)' for this document, which displays all the chapter names in order. My requirement is, when i click on a particular chapter in toc, the document should scroll to that point. For that i need to know height of each chapter ( height of each html file content). The point to be noted here is, the width of the document can changed and as HTML is reflowable, as width increases height decreases and vice-versa. So each time when height changes i need to find out the current height of each HTML page(or chapter) and hence calculate the distance to be scrolled. How can i find out the height of content of HTML page dynamically ? Thank you for the answer....

• Retrieve data from .dat file.

  We have an application which requires us to read data from a file (.dat) dynamically using deserialization. We are actually getting first object and it throws null pointer exception when we are accessing other objects using a "for" loop. File file=null; FileOutputStream fos=null; BufferedOutputStream bos=null; ObjectOutputStream oos=null; try{ file=new File("account4.dat"); fos=new FileOutputStream(file,true); bos=new BufferedOutputStream(fos); oos=new ObjectOutputStream(bos); oos.writeObject(m); System.out.println("object serialized"); amlist=new MemberAccountList(); oos.close(); } catch(Exception ex){ ex.printStackTrace(); } Reading objects: try{ MemberAccount m1; file=new File("account4.dat");//add your code here fis=new FileInputStream(file); bis=new BufferedInputStream(fis); ois=new ObjectInputStream(bis); System.out.println(ois.readObject()); while(ois.readObject()!=null){ m1=(MemberAccount)ois.readObject(); System.out.println(m1.toString()); }/mList.addElement(m1); // Here we have the issue throwing null pointer exception Enumeration elist=mList.elements(); while(elist.hasMoreElements()){ obj=elist.nextElement(); System.out.println(obj.toString()); }/ } catch(ClassNotFoundException e){ } catch(EOFException e){ System.out.println("end"); } catch(Exception ex){ ex.printStackTrace(); }

• SSIS Lookup with Lookup Component Vs Script Component.

  - by Nev_Rahd

  Hello, I need to load Dimensions from EDW Tables (which does maintain historical records) and is of type Key-Value-Parameter. My scenario is ok if got a record in EDW as below Key1 Key2 Code Value EffectiveDate EndDate CurrentFlag 100 555 01 AAA 2010-01-01 11.00.00 9999-12-31 Y 100 555 02 BBB 2010-01-01 11.00.00 9999-12-31 Y This need to be loaded into DM by pivoting it as key1 and key2 combinations makes Natural key for DM SK NK 01 02 EffectiveDate EndDate CurrentFlag 1 100-555 AAA BBB 2010-01-01 11.00.00 9999-12-31 Y My ssis package does this all good pivoting... looking up the incoming NK in DIM.. if new will insert .. else with further lookup with effective date and determine if the incoming for same natural key got any new (change) in attribute.. if so updates the current record byy setting its end date and insert the new one with new attribute value and pulling the recent records values for other attributes. My problem is if the same natural key comes twice with same attribute in single extract my first lookup which on natural key .. will let both records pass and try to insert.. where its fails. If i get distinct records on NK the second is not picked and need to run package again. So my question how can i configure lookup or alernative way to handle this scenario when same NK comes twice in single extract, would be able to insert first record if not exists in Dim table and for second one should be able to updated with the changes with reference to one inserted above. Not sure this makes sense what am trying to explain. Will attached the screenshot once back to work desk (on monday). Thanks

• ObjC: Alloc instance of Class and performing selectors on it leads to __CFRequireConcreteImplementat

  - by Arakyd

  Hi, I'm new to Objective-C and I'd like to abstract my database access using a model class like this: @interface LectureModel : NSMutableDictionary { } -(NSString*)title; -(NSDate*)begin; ... @end I use the dictionary methods setValue:forKey: to store attributes and return these in the getters. Now I want to read these models from a sqlite database by using the Class dynamically. + (NSArray*)findBySQL:(NSString*)sql intoModelClass:(Class)modelClass { NSMutableArray* models = [[[NSMutableArray alloc] init] autorelease]; sqlite3* db = sqlite3_open(...); sqlite3_stmt* result = NULL; sqlite3_prepare_v2(db, [sql UTF8String], -1, &result, NULL); while(sqlite3_step(result) == SQLITE_ROW) { id modelInstance = [[modelClass alloc] init]; for (int i = 0; i < sqlite3_column_count(result); ++i) { NSString* key = [NSString stringWithUTF8String:sqlite3_column_name(result, i)]; NSString* value = [NSString stringWithUTF8String:(const char*)sqlite3_column_text(result, i)]; if([modelInstance respondsToSelector:@selector(setValue:forKey:)]) [modelInstance setValue:value forKey:key]; } [models addObject:modelInstance]; } sqlite3_finalize(result); sqlite3_close(db); return models; } Funny thing is, the respondsToSelector: works, but if I try (in the debugger) to step over [modelInstance setValue:value forKey:key], it will throw an exception, and the stacktrace looks like: #0 0x302ac924 in ___TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION___ #1 0x991d9509 in objc_exception_throw #2 0x302d6e4d in __CFRequireConcreteImplementation #3 0x00024d92 in +[DBManager findBySQL:intoModelClass:] at DBManager.m:114 #4 0x0001ea86 in -[FavoritesViewController initializeTableData:] at FavoritesViewController.m:423 #5 0x0001ee41 in -[FavoritesViewController initializeTableData] at FavoritesViewController.m:540 #6 0x305359da in __NSFireDelayedPerform #7 0x302454a0 in CFRunLoopRunSpecific #8 0x30244628 in CFRunLoopRunInMode #9 0x32044c31 in GSEventRunModal #10 0x32044cf6 in GSEventRun #11 0x309021ee in UIApplicationMain #12 0x00002988 in main at main.m:14 So, what's wrong with this?

• Variant datatype library for C

  - by Joey Adams

  Is there a decent open-source C library for storing and manipulating dynamically-typed variables (a.k.a. variants)? I'm primarily interested in atomic values (int8, int16, int32, uint, strings, blobs, etc.), while JSON-style arrays and objects as well as custom objects would also be nice. A major case where such a library would be useful is in working with SQL databases. The most obvious feature of such a library would be a single type for all supported values, e.g.: struct Variant { enum Type type; union { int8_t int8_; int16_t int16_; // ... }; }; Other features might include converting Variant objects to/from C structures (using a binding table), converting values to/from strings, and integration with an existing database library such as SQLite. Note: I do not believe this is question is a duplicate of http://stackoverflow.com/questions/649649/any-library-for-generic-datatypes-in-c , which refers to "queues, trees, maps, lists". What I'm talking about focuses more on making working with SQL databases roughly as smooth as working with them in interpreted languages.

• Modularity in Flex

  - by Fernando

  I'm working on a pretty big application for Flex/Air. We are using GraniteDS and Tide to interact with the model from our Java EE server. I've been reading about modularization and Modules in Flex. The application has already been built, and I'm figuring a way out to re-design some classes and parts. From what I've read so far, I understand a Module is a different swf which can be dynamically load. Most of the tutorials/documentation are oriented to Flash "programmers" who are using Flex or Air instead of real developers, so that makes online resources harder to get. What I can't understand - yet - is how to encapsulate ActionScript classes or MXML views under this module. I've separated some of the code into libraries. For example, the generated code from Granite is in a "server" library. But I would like to separate parts of the logic with its Moderators, Controllers and Views. Are modules the way to go? Is there a "modules for dummies" or "head first Flex Modules for programmers" like tutorial in order to get a better perspective in order to build my architecture? When to choose libraries and when to choose modules? I'm using Flex 3.5, and a migration to Flex 4 is way far into the future, so no Flex 4 answers please, thanks!

• Practical size limitations for RDBMS

  - by grenade

  I am working on a project that must store very large datasets and associated reference data. I have never come across a project that required tables quite this large. I have proved that at least one development environment cannot cope at the database tier with the processing required by the complex queries against views that the application layer generates (views with multiple inner and outer joins, grouping, summing and averaging against tables with 90 million rows). The RDBMS that I have tested against is DB2 on AIX. The dev environment that failed was loaded with 1/20th of the volume that will be processed in production. I am assured that the production hardware is superior to the dev and staging hardware but I just don't believe that it will cope with the sheer volume of data and complexity of queries. Before the dev environment failed, it was taking in excess of 5 minutes to return a small dataset (several hundred rows) that was produced by a complex query (many joins, lots of grouping, summing and averaging) against the large tables. My gut feeling is that the db architecture must change so that the aggregations currently provided by the views are performed as part of an off-peak batch process. Now for my question. I am assured by people who claim to have experience of this sort of thing (which I do not) that my fears are unfounded. Are they? Can a modern RDBMS (SQL Server 2008, Oracle, DB2) cope with the volume and complexity I have described (given an appropriate amount of hardware) or are we in the realm of technologies like Google's BigTable? I'm hoping for answers from folks who have actually had to work with this sort of volume at a non-theoretical level.

• Change NSTimer interval for repeating timer.

  - by user300713

  Hi, I am running a mainLoop in Cocoa using an NSTimer set up like this: mainLoopTimer = [NSTimer scheduledTimerWithTimeInterval:1.0/fps target:self selector:@selector(mainloop) userInfo:nil repeats:YES]; [[NSRunLoop currentRunLoop] addTimer:mainLoopTimer forMode:NSEventTrackingRunLoopMode]; At Program startup I set the timeInterval to 0.0 so that the mainloop runs as fast as possible. Anyways, I would like to provide a function to set the framerate(and thus the time interval of the timer) to a specific value at runtime. Unfortunately as far as I know that means that I have to reinitialize the timer since Cocoa does not provide a function like "setTimerInterval" This is what I tried: - (void)setFrameRate:(float)aFps { NSLog(@"setFrameRate"); [mainLoopTimer invalidate]; mainLoopTimer = nil; mainLoopTimer = [NSTimer scheduledTimerWithTimeInterval:1.0/aFps target:self selector:@selector(mainloop) userInfo:nil repeats:YES]; [[NSRunLoop currentRunLoop] addTimer:mainLoopTimer forMode:NSEventTrackingRunLoopMode]; } but this throws the following error and stops the mainloop: 2010-06-09 11:14:15.868 myTarget[7313:a0f] setFrameRate 2010-06-09 11:14:15.868 myTarget[7313:a0f] * __NSAutoreleaseNoPool(): Object 0x40cd80 of class __NSCFDate autoreleased with no pool in place - just leaking 2010-06-09 11:14:15.869 myTarget[7313:a0f] * __NSAutoreleaseNoPool(): Object 0x40e700 of class NSCFTimer autoreleased with no pool in place - just leaking 0.614628 I also tried to recreate the timer using the "retain" keyword, but that didn't change anything. Any ideas about how to dynamically change the interval of an NSTimer at runtime? Thanks!

• Importing owl files

  - by Mikae Combarado

  Hello, I have a problem with importing owl files using owl api in Java. I successfully can import 2 owl files. However, a problem occurs, when I try to import 3 or more owl files that are integrated to each other. E.g. Base.owl -- base ontology Electronics.owl -- electronics ontology which imports Base.owl Telephone.owl -- telephone ontology which imports Base.owl and Electronics.owl When, I just import Base.owl and run Electronics.owl, it works smoothly. The code is given below: File fileBase = new File("filepath/Base.owl"); File fileElectronic = new File("filePath/Electronic.owl"); SimpleIRIMapper iriMapper = new SimpleIRIMapper(IRI.create("url/Base.owl"), IRI.create(fileBase)); OWLOntologyManager manager = OWLManager.createOWLOntologyManager(); manager.addIRIMapper(iriMapper); OWLOntology ont = manager.loadOntologyFromOntologyDocument(fileElectronic); However, when I want to load Telephone.owl, I just create an additional iriMapper and add it to the manager. The additional code is shown with ** : File fileBase = new File("filepath/Base.owl"); File fileElectronic = new File("filePath/Electronic.owl"); **File fileTelephone = new File("filePath/Telephone.owl");** SimpleIRIMapper iriMapper = new SimpleIRIMapper(IRI.create("url/Base.owl"), IRI.create(fileBase)); **SimpleIRIMapper iriMapper2 = new SimpleIRIMapper(IRI.create("url/Electronic.owl"), IRI.create(fileElectronic));** OWLOntologyManager manager = OWLManager.createOWLOntologyManager(); manager.addIRIMapper(iriMapper); **manager.addIRIMapper(iriMapper2);** OWLOntology ont = manager.loadOntologyFromOntologyDocument(**fileTelephone**); The code shown above gives this error : Could not load import: Import(url/Electronic.owl>) Reason: Could not loaded imported ontology: <url/Base.owl> Cause: null It would be really appreciated, if someone gives me a hand... Thanks in advance...

• Reporting System architecture for better performance

  - by pauloya

  Hi, We have a product that runs Sql Server Express 2005 and uses mainly ASP.NET. The database has around 200 tables, with a few (4 or 5) that can grow from 300 to 5000 rows per day and keep a history of 5 years, so they can grow to have 10 million rows. We have built a reporting platform, that allows customers to build reports based on templates, fields and filters. We face performance problems almost since the beginning, we try to keep reports display under 10 seconds but some of them go up to 25 seconds (specially on those customers with long history). We keep checking indexes and trying to improve the queries but we get the feeling that there's only so much we can do. Off course the fact that the queries are generated dynamically doesn't help with the optimization. We also added a few tables that keep redundant data, but then we have the added problem of maintaining this data up to date, and also Sql Express has a limit on the size of databases. We are now facing a point where we have to decide if we want to give up real time reports, or maybe cut the history to be able to have better performance. I would like to ask what is the recommended approach for this kind of systems. Also, should we start looking for third party tools/platforms? I know OLAP can be an option but can we make it work on Sql Server Express, or at least with a license that is cheap enough to distribute to thousands of deployments? Thanks

  A little background on the application that I am gonna talk about in the next few lines: XYZ is a data masking workbench eclipse RCP application: You give it a source table column, and a target table column, it would apply a trasformation (encryption/shuffling/etc) and copy the row data from source table to target table. Now, when I mask n tables at a time, n threads are launched by this app. Here is the issue: I have run into a production issue on first roll out of the above said app. Unfortunately, I don't have any logs to get to the root. However, I tried to run this app in test region and do a stress test. When I collected .hprof files and ran 'em through an analyzer (yourKit), I noticed that objects of oracle.jdbc.driver.T4CPreparedStatement was retaining heap. The analysis also tells me that one of my classes is holding a reference to this preparedstatement object and thereby, n threads have n such objects. T4CPreparedStatement seemed to have character arrays: lastBoundChars and bindChars each of size char[300000]. So, I researched a bit (google!), obtained ojdbc6.jar and tried decompiling T4CPreparedStatement. I see that T4CPreparedStatement extends OraclePreparedStatement, which dynamically manages array size of lastBoundChars and bindChars. So, my questions here are: Have you ever run into an issue like this? Do you know the significance of lastBoundChars / bindChars? I am new to profiling, so do you think I am not doing it correct? (I also ran the hprofs through MAT - and this was the main identified issue - so, I don't really think I could be wrong?) I have found something similar on the web here: http://forums.oracle.com/forums/thread.jspa?messageID=2860681 Appreciate your suggestions / advice.

• is delete p where p is a pointer to array a memory leak ?

  - by Eli

  following a discussion in a software meeting I setup to find out if deleting an dynamically allocated primitive array with plain delete will cause a memory leak. I have written this tiny program and compiled with visual studio 2008 running on windows XP: #include "stdafx.h" #include "Windows.h" const unsigned long BLOCK_SIZE = 1024*100000; int _tmain() { for (unsigned int i =0; i < 1024*1000; i++) { int* p = new int[1024*100000]; for (int j =0;j<BLOCK_SIZE;j++) p[j]= j % 2; Sleep(1000); delete p; } } I than monitored the memory consumption of my application using task manager, surprisingly the memory was allocated and freed correctly, allocated memory did not steadily increase as was expected I've modified my test program to allocate a non primitive type array : #include "stdafx.h" #include "Windows.h" struct aStruct { aStruct() : i(1), j(0) {} int i; char j; } NonePrimitive; const unsigned long BLOCK_SIZE = 1024*100000; int _tmain() { for (unsigned int i =0; i < 1024*100000; i++) { aStruct* p = new aStruct[1024*100000]; Sleep(1000); delete p; } } after running for for 10 minutes there was no meaningful increase in memory I compiled the project with warning level 4 and got no warnings. is it possible that the visual studio run time keep track of the allocated objects types so there is no different between delete and delete[] in that environment ?

• SSL with private key on an HSM

  - by Jason

  I have a client-server architecture in my application that uses SSL. Currently, the private key is stored in CAPI's key store location. For security reasons, I'd like to store the key in a safer place, ideally a hardware signing module (HSM) that is built for this purpose. Unfortunately, with the private key stored on such a device, I can't figure out how to use it in my application. On the server, I am simply using the SslStream class and the AuthenticateAsServer(...) call. This method takes an X509Certificate object that has its private key loaded, but since the private key is stored in a secure (e.g. non exportable) location on the HSM, I don't know how to do this. On the client, I am using an HttpWebRequest object and then using the ClientCertificates property to add my client authentication certificate, but I have the same problem here: how do I get the private key? I know there are some HSMs that act as SSL accelerators but I don't really need an accelerator. Also, these products tend to have special integration with web servers such as IIS and Apache which I'm not using. Any ideas? The only thing I can think of would be to write my own SSL library that would allow me to hand off the signing portion of the transaction to the HSM, but this seems like a huge amount of work.

• Removing a fields from a dynamic ModelForm

  - by Jérôme Pigeot

  In a ModelForm, i have to test user permissions to let them filling the right fields : It is defined like this: class TitleForm(ModelForm): def __init__(self, user, *args, **kwargs): super(TitleForm,self).__init__(*args, **kwargs) choices = [] # company if user.has_perm("myapp.perm_company"): self.fields['company'] = forms.ModelChoiceField(widget=forms.HiddenInput(), queryset=Company.objects.all(), required=False) choices.append('Company') # association if user.has_perm("myapp.perm_association") self.fields['association'] = forms.ModelChoiceField(widget=forms.HiddenInput(), queryset=Association.objects.all(), required=False) choices.append('Association') # choices self.fields['type_resource'] = forms.ChoiceField(choices = choices) class Meta: Model = Title This ModelForm does the work : i hide each field on the template and make them appearing thanks to javascript... The problem is this ModelForm is that each field defined in the model will be displayed on the template. I would like to remove them from the form if they are not needed: exemple : if the user has no right on the model Company, it won't be used it in the rendered form in the template. The problem of that is you have to put the list of fields in the Meta class of the form with fields or exclude attribute, but i don't know how to manage them dynamically. Any Idea?? Thanks by advance for any answer.

• Issue with IHttpHandler and relative URLs

  - by vtortola

  Hi, I've developed a IHttpHandler class and I've configured it as verb="*" path="*", so I'm handling all the request with it in an attempt of create my own REST implementation for a test web site that generates the html dynamically. So, when a request for a .css file arrives, I've to do something like context.Response.WriteFile(Server.MapPath(url)) ... same for pictures and so on, I have to response everything myself. My main issue, is when I put relative URLs in the anchors; for example, I have main page with a link like this <a href="page1">Go to Page 1</a> , and in Page 1 I have another link <a href="page2">Go to Page 2</a>. Page 1 and 2 are supposed to be at the same level (http://host/page1 and http://host/page2, but when I click in Go to Page 2, I got this url in the handler: ~/page1/~/page2 ... what is a pain, because I have to do an url = url.SubString(url.LastIndexOf('~')) for clean it, although I feel that there is nothing wrong and this behavior is totally normal. Right now, I can cope with it, but I think that in the future this is gonna bring me some headache. I've tried to set all the links with absolute URLs using the information of context.Request.Url, but it's also a pain :D, so I'd like to know if there is a nicer way to do these kind of things. Don't hesitate in giving me pretty obvious responses because I'm pretty new in web development and probably I'm skipping something basic about URLs, Http and so on. Thanks in advance and kind regards.

• Opencv application crashes at runtime with error code 0x0000142

  - by Tuan Anh

  I have openCV and minGW installed with codeblock IDE following the instructions found here http://kevinhughes.ca/tutorials/opencv-install-on-windows-with-codeblocks-and-mingw/ i tried the simple image loading program in the article and the build process went fine. but when i tried running the output program, it crashes with the error message "the application was unable to start correctly (0xc0000142). Click OK to close the application." I used Dependency Walker to see if the program failed to load dll module and here's the output screen of Dependency Walker https://www.dropbox.com/s/f9iaftdt8atjwpl/Screenshot%202013-11-05%2022.21.45.png i am not used to DW but as i can see in its output screen, some openCV dll failed to load and the loaded Windows DLL were 64 bit instead of 32 bit (as minGW is 32 bit). I can't figure out why as i already configure the Path environment variable for the bin directory of openCV and the app still can not load the dll modules. And i think that Windows will automatically load the proper 32 bit DLLs when a 32 bit app is run but this situation the app still failed to load. Anyone has ideas?
