• Why is Available Physical Memory (dwAvailPhys) > Available Virtual Memory (dwAvailVirtual) in call G

  - by Andrew

  I am playing with an MSDN sample to do memory stress testing (see: http://msdn.microsoft.com/en-us/magazine/cc163613.aspx) and an extension of that tool that specifically eats physical memory (see http://www.donationcoder.com/Forums/bb/index.php?topic=14895.0;prev_next=next). I am obviously confused though on the differences between Virtual and Physical Memory. I thought each process has 2 GB of virtual memory (although I also read 1.5 GB because of "overhead". My understanding was that some/all/none of this virtual memory could be physical memory, and the amount of physical memory used by a process could change over time (memory could be swapped out to disc, etc.)I further thought that, in general, when you allocate memory, the operating system could use physical memory or virtual memory. From this, I conclude that dwAvailVirtual should always be equal to or greater than dwAvailPhys in the call GlobalMemoryStatus. However, I often (always?) see the opposite. What am I missing. I apologize in advance if my question is not well formed. I'm still trying to get my head around the whole memory management system in Windows. Tutorials/Explanations/Book recs are most welcome!

• Jquery star rating plugin and cancel rating button

  - by Roger

  Using this plugin: http://www.fyneworks.com/jquery/star-rating/#tab-Testing I have a simple callback function that picks up the id from the radio buttons: <input type="radio" class="auto-submit-star {split:2}" id="myid" value="1" /> $('.auto-submit-star').rating({ callback: function(value, link){ alert($(this).attr('id')); } }); This works fine, but if the user clicks on the cancel button, then it can't read the id of it. In the js, I think the cancel button is added dynamically with: control.cancel = $('<div class="rating-cancel"><a title="' + control.cancel + '">' + control.cancelValue + '</a></div>') If I add an id to it like this: control.cancel = $('<div class="rating-cancel"><a id="someid" title="' + control.cancel + '">' + control.cancelValue + '</a></div>') How could I read the id? This would be undefined. I can set a class and use $('.myclass').attr('id') but I will have multiple ratings on one page so I'll need something similar to "this". Or is it possible for the cancel button to pick up the id of the corresponding radio buttons?

• Galleria and Infinite carousel and ajax

  - by John the horn

  Hy all you smart people I am using Galleria plugin for a image gallery on a page this page is loaded in a frame page using ajax this is the ajax $(document).ready(function() { function loadTab(pageUrl) { $.ajax( { url: pageUrl, cache: true, success: function(load) { $("#tabcontent").empty().append(load); } }); } $(document).ready(function() { $("#tab1").ready(function() { loadTab("acasa.html"); }); $("#tab1").click(function() { loadTab("acasa.html"); }); $("#tab2").click(function() { loadTab("desprenoi.html"); }); $("#tab3").click(function() { loadTab("servici.html"); }); $("#tab4").click(function() { loadTab("parteneri.html"); }); $("#tab5").click(function() { loadTab("galerie.html"); }); $("#tab6").click(function() { loadTab("contact.php"); }); }); }); On the frame page Im using Infinite gallery that uses <ul></ul> tags my problem is that offline, testing the page it works perfect but on the server(online) the gallery using galleria goes to the dogs. What I mean is that I have in stead of the gallery the a list of all the images. Can enione help this pore nube ? Thx for your time. P.S. Can enyone help me find a better ajax script :D

• "Programming In Haskell" error in sat function

  - by Matt Ellen

  I'm in chapter 8 of Graham Hutton's Programming in Haskell and I'm copying the code and testing it in GHC. See the slides here: http://www.cis.syr.edu/~sueo/cis352/chapter8.pdf in particular slide 15 The relevant code I've copied so far is: type Parser a = String -> [(a, String)] pih_return :: a -> Parser a pih_return v = \inp -> [(v, inp)] failure :: Parser a failure = \inp -> [] item :: Parser Char item = \inp -> case inp of [] -> [] (x:xs) -> [(x,xs)] parse :: Parser a -> String -> [(a, String)] parse p inp = p inp sat :: (Char -> Bool) -> Parser Char sat p = do x <- item if p x then pih_return x else failure I have changed the name of the return function from the book to pih_return so that it doesn't clash with the Prelude return function. The errors are in the last function sat. I have copied this directly from the book. As you can probably see p is a function from Char to Bool (e.g. isDigit) and x is of type [(Char, String)], so that's the first error. Then pih_return takes a value v and returns [(v, inp)] where inp is a String. This causes an error in sat because the v being passed is x which is not a Char. I have come up with this solution, by explicitly including inp into sat sat :: (Char -> Bool) -> Parser Char sat p inp = do x <- item inp if p (fst x) then pih_return (fst x) inp else failure inp Is this the best way to solve the issue?

• Programmatically copying custom content type and columns from one web to another

  - by BeraCim

  Hi all: I'm experiencing a very stubborn problem when copying custom content type and its columns from one web to another within the same site. Basically, this is the code that I have: foreach (SPField field in existingWeb.Fields) { if (!destinationWeb.Fields.ContainsField(field.Title)) { destinationWeb.Fields.AddFieldAsXml(field.SchemaXml); destinationWeb.Update(); } } foreach (SPContentType existingWebCt in destinationWeb.ContentType) { SPContentType newContentType = new SPContentType(existingWebCt.Parent, destinationWeb.ContentTypes, existingWebCt.Name); foreach (SPFieldLink fieldLink in existingWebCt.FieldLinks) { SPField sourceField = existingWebCt.Fields[fieldLink.Id]; if (destinationWeb.Fields.ContainsField(sourceField.Title)) { SPFieldLink destinationWebFieldLink = new SPFieldLink(destinationWeb.Fields[sourceField.Title]); newContentType.FieldLinks.Add(destinationWebFieldLink); } } } existingWeb and destinationWeb are 2 webs within the same site. The code runs fine. But the problem is that in the SITE Content Type screen (under site settings), when I click the custom column link in the custom content type, I got an error saying: Invalid field name {UID}. The UID is the same UID as the custom column in the existing site. I checked with my web settings after completion. I can see the custom list (which I created with an item for testing purpose), but the custom column is gone from the view (though the actual data is still there... just have to check the box to get it to display). But I think that is less important... more of fyi. I've also gotten a variety of different exceptions should I copy things wrongly. Google has failed to help me out on this one. Does anyone know what I'm missing in order to get that link to work again? Thanks.

• DrScheme versus mzscheme: treatment of definitions

  - by speciousfool

  One long term project I have is working through all the exercises of SICP. I noticed something a bit odd with the most recent exercise. I am testing a Huffman encoding tree. When I execute the following code in DrScheme I get the expected result: (a d a b b c a) However, if I execute this same code in mzscheme by calling (load "2.67.scm") or by running mzscheme -f 2.67.scm, it reports: symbols: expected symbols as arguments, given: (leaf D 1) My question is: why? Is it because mzscheme and drscheme use different rules for loading program definitions? The program code is below. ;; Define an encoding tree and a sample message ;; Use the decode procedure to decode the message, and give the result. (define (make-leaf symbol weight) (list 'leaf symbol weight)) (define (leaf? object) (eq? (car object) 'leaf)) (define (symbol-leaf x) (cadr x)) (define (weight-leaf x) (caddr x)) (define (make-code-tree left right) (list left right (append (symbols left) (symbols right)) (+ (weight left) (weight right)))) (define (left-branch tree) (car tree)) (define (right-branch tree) (cadr tree)) (define (symbols tree) (if (leaf? tree) (list (symbol-leaf tree)) (caddr tree))) (define (weight tree) (if (leaf? tree) (weight-leaf tree) (cadddr tree))) (define (decode bits tree) (define (decode-1 bits current-branch) (if (null? bits) '() (let ((next-branch (choose-branch (car bits) current-branch))) (if (leaf? next-branch) (cons (symbol-leaf next-branch) (decode-1 (cdr bits) tree)) (decode-1 (cdr bits) next-branch))))) (decode-1 bits tree)) (define (choose-branch bit branch) (cond ((= bit 0) (left-branch branch)) ((= bit 1) (right-branch branch)) (else (error "bad bit -- CHOOSE-BRANCH" bit)))) (define (test s-exp) (display s-exp) (newline)) (define sample-tree (make-code-tree (make-leaf 'A 4) (make-code-tree (make-leaf 'B 2) (make-code-tree (make-leaf 'D 1) (make-leaf 'C 1))))) (define sample-message '(0 1 1 0 0 1 0 1 0 1 1 1 0)) (test (decode sample-message sample-tree))

• review count and rating using an image - schema.org

  - by Joel

  I need some help getting some rich snippets to my site I inserted the review microdata following the instructions given on schema.org here http://schema.org/docs/gs.html#advanced_missing using the star-image for rating and the text for review count, but testing it with the test tool it showed nothing. Example page where we use the microdata for the reviews. and here is what I used <div itemprop="reviews" itemscope itemtype="http://schema.org/AggregateRating"> <A HREF="javascript:an();"><img src="/images/stars/4.5.gif" border=0></a> <meta itemprop="ratingValue" content="4.5" /> <meta itemprop="bestRating" content="5" /> <BR><span class="bottomnavfooter"><A HREF="javascript:an();">Read (<span itemprop="ratingCount">70</span>) Reviews</A </span></div> I then created a static test page and made some change using instructions Google provided here http://www.google.com/support/webmasters/bin/answer.py?answer=172705 (which is different from what I found on schema.org!!) but still the test returned only product name not the price or the reviews. Here is my test page - Can you please see where I'm going wrong Thanks much!!

• How to create a rails staging environment in engineyard?

  - by siulamvictor

  I have a production instance in engineyard up and running well. I would like to create a new staging instance for internal testing. I cloned the existing production instance, changed Framework Environment to staging. I can deploy all the code to staging instance from Github. Engineyard reported the server is fully configured and ready. I have subdomain-fu in my Rails app, as I have some subdomain handling in my app. I set the subdomain initializer like this.... SubdomainFu.tld_sizes = {:development => 1, :test => 0, :production => 1, :staging => 2} As the production instance is using the domain xxxxx.com, I would like my staging instance use the domain staging.xxxxx.com. But I got an error when open this domain. Seems the app use xxxxx.com as domain but not the staging.xxxxx.com. I checked the engineyard database.yml. It use xxxxx_production database, I supposed it should be xxxxx_staging. Seems the engineyard instance is not set to staging environment, but just clone all the setting from production server. Does anyone have experience with this and can show me the way on how to fix it? Thanks. :)

• maven dependencies and jetty - avoiding deploy

  - by James Cooper

  Hi, I have a project with 3 artifacts: common - entities, business logic. no UI code webapp-a - a public web app webapp-b - an admin web app webapp-a and webapp-b depend on common. common is configured to deploy to a local maven repo. so far so good. I have IntelliJ configured so that each artifact is a separate module. Module dependencies are configured properly. I can add a new method to a class in common and immediately use that method in a class in a webapp. However, when I run mvn jetty:run it uses the currently deployed common snapshot in my repository. It does not use my local classes. If I add a method to a class in common, it compiles fine, but blows up at runtime. So is it possible to either: a) Convince jetty:run to use my local common build output or b) Deploy my common output to my local ~/.m2/repo while I'm testing locally before I want to commit/deploy or c) some other solution? thank you! -- James

• Crystal reports 11 RDC (COM API) displays printer dialog even when I tell it not to prompt

  - by bdonlan

  I'm using Crystal Reports 11's RDC (COM) API to print. My code looks like this: HRESULT res = m_Report->SelectPrinter(b_driver, b_device, b_port); if (FAILED(res)) return res; // For these calls, the #import wrapper throws on error m_Report->PutPrinterDuplex(dmDuplex); m_Report->PutPaperSize(dmPaperSize); m_Report->PutPaperSource((CRPaperSource)pdlg->GetDevMode()->dmDefaultSource); if (m_Report->GetPaperOrientation() == crDefaultPaperOrientation) m_Report->PutPaperOrientation(crPortrait); VARIANT vfalse; VariantInit(&vfalse); vfalse.vt=VT_BOOL; vfalse.boolVal=0; res = m_Report->PrintOut(vfalse); However, at the end of all this, crystal reports still shows its own printer selection dialog - but only for some reports, it seems. Why does crystal reports show a print dialog even when I pass false for promptUser? And how, then, can I suppress crystal reports' internal printer selection dialog and force it to use my values? Edit: Whoops, CR11, not CR9. Some further information: The reports that work properly (ie, do not show the print dialog) are generated internally using the RDC API; we create a new report object, import subreports into it, then print the result. No problem there. The reports that do not work properly (ie, force the print dialog to open) have been created with a previous version of crystal reports; however, opening and saving the report does not seem to help. Sample reports in the Crystal Reports installation directory show the same problem. I tried reproducing with VBScript; however, the result was that nothing was printed at all (no dialog, no nothing): Set app = CreateObject("CrystalRuntime.Application.11") Set report = app.OpenReport("C:\Program Files\Business Objects\Crystal Reports 11.5\Samples\en\Reports\General Business\Inventory Crosstab.rpt") report.PrintOut(True) rem Testing with a True parameter to force a print dialog - but no printout and nothing appears (no error either though)

• Google Maps Api android key

• Using a CALayer in UITableViewCell

  - by Brian

  On each cell of my table view I want to have a bar that the user can slide out from the right. On the bar I plan to have icons. So, to do this I subclassed UITableViewCell. On the cell I have implemented drawRect and in there I have already drawn a gradient and background color on the cell. From there, I can create a CALayer, give it a frame & background color, and add it as a sub layer to the Views subLayers array. I can do all that and it will display my layer on each UITableViewCell. I have added touch events to the cell so I can detect when the user touches the cell and for testing I have made it so when the user swipes, my CALayer gets wider. But the issue is, when the UITableView scrolls and reuses a cell whose CALayer has been widened, it doesn't recreate the CALayer. I have tried [myLayer setNeedsDisplay] and used the drawLayer:inContext method of its delegate and it doesn't get called. I have also tried telling call setNeedsDisplay on the cell in my UITableViewController hoping that that will cause a redraw, but it doesn't work. I'm not sure what I'm missing. I am new to CoreGraphics & CoreAnimation. I have read through the CoreAnimation Developers Guide, but I'm assuming I missing something. Any help would be great.

• WPF animation/UI features performance and benchmarking

  - by Rich

  I'm working on a relatively small proof-of-concept for some line of business stuff with some fancy WPF UI work. Without even going too crazy, I'm already seeing some really poor performance when using a lot of the features that I thought were the main reason to consider WPF for UI building in the first place. I asked a question on here about why my animation was being stalled the first time it was run, and at the end what I found was that a very simple UserControl was taking almost half a second just to build its visual tree. I was able to get a work around to the symptom, but the fact that it takes that long to initialize a simple control really bothers me. Now, I'm testing my animation with and without the DropShadowEffect, and the result is night and day. A subtle drop shadow makes my control look so much nicer, but it completely ruins the smoothness of the animation. Let me not even start with the font rendering either. The calculation of my animations when the control has a bunch of gradient brushes and a drop shadow make the text blurry for about a full second and then slowly come into focus. So, I guess my question is if there are known studies, blog posts, or articles detailing which features are a hazard in the current version of WPF for business critical applications. Are things like Effects (ie. DropShadowEffect), gradient brushes, key frame animations, etc going to have too much of a negative effect on render quality (or maybe the combinations of these things)? Is the final version of WPF 4.0 going to correct some of these issues? I've read that VS2010 beta has some of these same issues and that they are supposed to be resolved by final release. Is that because of improvements to WPF itself or because half of the application will be rebuilt with the previous technology?

• Forcing CLLocationManager updates - does it help or hurt?

  - by Steve N

  I've been trying to find any way to optimize the performance of my location-based iPhone application and have seen some people mention that you can force location updates by starting and stopping your CLLocationManager. I need the best accuracy I can get, and the user in my case would probably like to see updates every few seconds (say, 10 seconds) as they walk around. I've set the filters accordingly, but I notice that sometimes I don't get any updates on the device for quite some time. I'm testing the following approach, which forces an update when a fixed time interval passes (I'm using 20 seconds). My gut tells me this really won't help me provide more accurate updates to the user, and that just leaving CLLocationManager running all the time is probably the best approach. - (void)forceLocationUpdate { [[LocationManager locationManager] stopUpdates]; [[LocationManager locationManager] startUpdates]; [self performSelector:@selector(forceLocationUpdate) withObject:nil afterDelay:20.0]; } My question is- does forcing updates from CLLocationManager actually improve core location performance? Does it hurt performance? If I'm outside in an open field with good GPS reception, will this help then? Does anyone have experience trying this? Thanks in advance, Steve

• Required Working Precision for the BBP Algorithm?

  - by brainfsck

  Hello, I'm looking to compute the nth digit of Pi in a low-memory environment. As I don't have decimals available to me, this integer-only BBP algorithm in Python has been a great starting point. I only need to calculate one digit of Pi at a time. How can I determine the lowest I can set D, the "number of digits of working precision"? D=4 gives me many correct digits, but a few digits will be off by one. For example, computing digit 393 with precision of 4 gives me 0xafda, from which I extract the digit 0xa. However, the correct digit is 0xb. No matter how high I set D, it seems that testing a sufficient number of digits finds an one where the formula returns an incorrect value. I've tried upping the precision when the digit is "close" to another, e.g. 0x3fff or 0x1000, but cannot find any good definition of "close"; for instance, calculating at digit 9798 gives me 0xcde6 , which is not very close to 0xd000, but the correct digit is 0xd. Can anyone help me figure out how much working precision is needed to calculate a given digit using this algorithm? Thank you,

• Parameterized Queries /Without/ using queries.

  - by Aren B

  I've got a bit of a poor situation here. I'm stuck working with commerce server, which doesn't do a whole lot of sanitization/parameterization. I'm trying to build up my queries to prevent SQL Injection, however some things like the searches / where clause on the search object need to be built up, and there's no parameterized interface. Basically, I cannot parameterize, however I was hoping to be able to use the same engine to BUILD my query text if possible. Is there a way to do this, aside from writing my own parameterizing engine which will probably still not be as good as parameterized queries? Update: Example The where clause has to be built up as a sql query where clause essentially: CatalogSearch search = /// Create Search object from commerce server search.WhereClause = string.Format("[cy_list_price] > {0} AND [Hide] is not NULL AND [DateOfIntroduction] BETWEEN '{1}' AND '{2}'", 12.99m, DateTime.Now.AddDays(-2), DateTime.Now); *Above Example is how you refine the search, however we've done some testing, this string is NOT SANITIZED. This is where my problem lies, because any of those inputs in the .Format could be user input, and while i can clean up my input from text-boxes easily, I'm going to miss edge cases, it's just the nature of things. I do not have the option here to use a parameterized query because Commerce Server has some insane backwards logic in how it handles the extensible set of fields (schema) & the free-text search words are pre-compiled somewhere. This means I cannot go directly to the sql tables What i'd /love/ to see is something along the lines of: SqlCommand cmd = new SqlCommand("[cy_list_price] > @MinPrice AND [DateOfIntroduction] BETWEEN @StartDate AND @EndDate"); cmd.Parameters.AddWithValue("@MinPrice", 12.99m); cmd.Parameters.AddWithValue("@StartDate", DateTime.Now.AddDays(-2)); cmd.Parameters.AddWithValue("@EndDate", DateTime.Now); CatalogSearch search = /// constructor search.WhereClause = cmd.ToSqlString();

• Custom title with image

  - by Alex Volovoy

  Hi all, i'm creating custom title for activity by disabling standard one and managing everything myself. I wonder if it's possible to replace/theme standart title to my needs. I can customize size, background image, and text via themes by changing windowXYZStyle items. The only thing i couldn't find - how i can add image instead of text. I've tried requestWindowFeature(Window.FEATURE_CUSTOM_TITLE) and assign custom layout - but it doesn't seems to work. EDIT : Here is a report of testing suggestions, code is below - result - image view is not showing up. Activity public class SettingsActivity extends PreferenceActivity { @Override protected void onCreate(Bundle savedInstanceState) { requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title); super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.settings); } } XML : <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="26dip" android:paddingLeft="5dip" android:background="@drawable/titlebar_bg" android:layout_gravity="left|center" > <ImageView android:id="@+id/logo" android:src="@drawable/title_logo" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>

• Experience migrating legacy Cobol/PL1 to Java

  - by MadMurf

  ORIGINAL Q: I'm wondering if anyone has had experience of migrating a large Cobol/PL1 codebase to Java? How automated was the process and how maintainable was the output? How did the move from transactional to OO work out? Any lessons learned along the way or resources/white papers that may be of benefit would be appreciated. EDIT 7/7: Certainly the NACA approach is interesting, the ability to continue making your BAU changes to the COBOL code right up to the point of releasing the JAVA version has merit for any organization. The argument for procedural Java in the same layout as the COBOL to give the coders a sense of comfort while familiarizing with the Java language is a valid argument for a large organisation with a large code base. As @Didier points out the $3mil annual saving gives scope for generous padding on any BAU changes going forward to refactor the code on an ongoing basis. As he puts it if you care about your people you find a way to keep them happy while gradually challenging them. The problem as I see it with the suggestion from @duffymo to Best to try and really understand the problem at its roots and re-express it as an object-oriented system is that if you have any BAU changes ongoing then during the LONG project lifetime of coding your new OO system you end up coding & testing changes on the double. That is a major benefit of the NACA approach. I've had some experience of migrating Client-Server applications to a web implementation and this was one of the major issues we encountered, constantly shifting requirements due to BAU changes. It made PM & scheduling a real challenge. Thanks to @hhafez who's experience is nicely put as "similar but slightly different" and has had a reasonably satisfactory experience of an automatic code migration from Ada to Java. Thanks @Didier for contributing, I'm still studying your approach and if I have any Q's I'll drop you a line.

• Python interface to PayPal - urllib.urlencode non-ASCII characters failing

  - by krys

  I am trying to implement PayPal IPN functionality. The basic protocol is as such: The client is redirected from my site to PayPal's site to complete payment. He logs into his account, authorizes payment. PayPal calls a page on my server passing in details as POST. Details include a person's name, address, and payment info etc. I need to call a URL on PayPal's site internally from my processing page passing back all the params that were passed in abovem and an additional one called 'cmd' with a value of '_notify-validate'. When I try to urllib.urlencode the params which PayPal has sent to me, I get a: While calling send_response_to_paypal. Traceback (most recent call last): File "<snip>/account/paypal/views.py", line 108, in process_paypal_ipn verify_result = send_response_to_paypal(params) File "<snip>/account/paypal/views.py", line 41, in send_response_to_paypal params = urllib.urlencode(params) File "/usr/local/lib/python2.6/urllib.py", line 1261, in urlencode v = quote_plus(str(v)) UnicodeEncodeError: 'ascii' codec can't encode character u'\ufffd' in position 9: ordinal not in range(128) I understand that urlencode does ASCII encoding, and in certain cases, a user's contact info can contain non-ASCII characters.

My question is, how do I encode non-ASCII characters for POSTing to a URL using urllib2.urlopen(req) (or other method) Details: I read the params in PayPal's original request as follows (the GET is for testing): def read_ipn_params(request): if request.POST: params= request.POST.copy() if "ipn_auth" in request.GET: params["ipn_auth"]=request.GET["ipn_auth"] return params else: return request.GET.copy() The code I use for sending back the request to PayPal from the processing page is: def send_response_to_paypal(params): params['cmd']='_notify-validate' params = urllib.urlencode(params) req = urllib2.Request(PAYPAL_API_WEBSITE, params) req.add_header("Content-type", "application/x-www-form-urlencoded") response = urllib2.urlopen(req) status = response.read() if not status == "VERIFIED": logging.warn("PayPal cannot verify IPN responses: " + status) return False return True Obviously, the problem only arises if someone's name or address or other field used for the PayPal payment does not fall into the ASCII range.

• visual studio 2008 vs 2010 Pro unmanaged code

  - by bartek

  Hi, I'm a C++ programmer, I use Visual Studio 2008 Professional, only unmanaged code. I'm thinking of buying VS 2010 Pro. I'm confused, I don't know what are differences between those two. I know that, in plus, it has tr1 included. When I started using 2008 edition I was very pleased to see f.e. unit testing support but all new features are only for managed code. The C++ debugger in 2008 is very good, better than 2003 edition one. I would't like to buy a new tool and discover that I gained nothing and lost some functionality ( because f.e. something was moved to higher version). Once upon a time I switched from very good VS6 to VS 2003.Net and imagine what, after some time I discovered that Pro has no support for code optimalization. It is wonderful how Microsoft makes money. I wouldn't like to experience something like that again. What do you think, what can you recommended?

• Exception in setDrawingCache in Android 1.5?

  - by sunil

  Hi, I am developing an application where I am using setDrawingCache and then once I get the Bitmap I destroy the cache by using destroyDrawingCache(). The application has been developed with Android SDK 1.6. When testing the application in emulator with Android 1.5 the application throws NullPointerException when try to manipulate the Bitmap returned by getDrawingCache(). It probably gives error since getDrawingCache returns null. The interesting thing in this is that the NullPointerException comes only after I run the application twice or thrice. It means I am able to get the Bitmap for two times and then it throws this exception. The error that I am getting is as below java.lang.NullPointerException E/AndroidRuntime( 1036): at com.babbleville.HomeScreenActivity.resizeBitmap(HomeScreenActivity.java: 394) E/AndroidRuntime( 1036): at com.babbleville.HomeScreenActivity.access $0(HomeScreenActivity.java:392) E/AndroidRuntime( 1036): at com.babbleville.HomeScreenActivity $1.handleMessage(HomeScreenActivity.java:327) E/AndroidRuntime( 1036): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 1036): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 1036): at android.app.ActivityThread.main(ActivityThread.java:3948) E/AndroidRuntime( 1036): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 1036): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 1036): at com.android.internal.os.ZygoteInit $MethodAndArgsCaller.run(ZygoteInit.java:782) E/AndroidRuntime( 1036): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:540) E/AndroidRuntime( 1036): at dalvik.system.NativeStart.main(Native Method) Can someone please let me know the problem?

• JavaScript and JQuery - Encoding HTML

  - by user70192

  Hello, I have a web page that has a textarea defined on it like so: <textarea id="myTextArea" rows="6" cols="75"></textarea> There is a chance that a user may enter single and double quotes in this field. For instance, I have been testing with the following string: Just testin' using single and double "quotes". I'm hoping the end of this task is comin'. Additionally, the user may enter HTML code, which I would prefer to prevent. Regardless, I am passing the contents of this textarea onto web service. I must encode the contents of the textarea in JavaScript before I can send it on. Currently, I'm trying the following: var contents $('<div/>').text($("#myTextArea).val()).html(); alert(contents); I was expecting contents to display Just testin&#39; using single and double &#34;quotes&#34;. I&#39;m hoping the end of this task is comin&#39;. Instead, the original string is printed out. Beyond just double-and-single quotes, there are a variety of entities to consider. Because of this, I was assuming there would be a way to encode HTML before passing it on. Can someone please tell me how to do this? Thank you,

• 'Invalid column name [ColumnName]' on a nested linq query.

  - by Joe

  I've got the following query: ATable .GroupBy(x=> new {FieldA = x.FieldAID, FieldB = x.FieldBID, FieldC = x.FieldCID}) .Select(x=>new {FieldA = x.Key.FieldA, ..., last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault().Timestamp}) results in: SqlException: Invalid column name 'FieldAID' x 5 SqlException: Invalid column name 'FieldBID' x 5 SqlException: Invalid column name 'FieldCID' x 1 I've worked out it has to do with the last query to Timestamp because this works: ATable .GroupBy(x=> new {FieldA = x.FieldAID, FieldB = x.FieldBID, FieldC = x.FieldCID}) .Select(x=>new {FieldA = x.Key.FieldA, ..., last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault()}) The query has been simplified. The purpose is to group by a set of variables and then show the last time this grouping occured in the db. I'm using Linqpad 4 to generate these results so the Timestamp gives me a string whereas FirstOrDefault gives me the whole object which isn't ideal. Update On further testing I've noticed that the number and type of SQLException is related to the class created in the groupby clause. So, ATable .GroupBy(x=> new {FieldA = x.FieldAID}) .Select(x=>new {FieldA = x.Key.FieldA, last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault()}) results in SqlException: Invalid column name 'FieldAID' x 5

• Validation without ServiceLocator

  - by Dmitriy Nagirnyak

  Hi, I am getting back again and again to it thinking about the best way to perform validation on POCO objects that need access to some context (ISession in NH, IRepository for example). The only option I still can see is to use S*ervice Locator*, so my validation would look like: public User : ICanValidate { public User() {} // We need this constructor (so no context known) public virtual string Username { get; set; } public IEnumerable<ValidationError> Validate() { if (ServiceLocator.GetService<IUserRepository>().FindUserByUsername(Username) != null) yield return new ValidationError("Username", "User already exists.") } } I already use Inversion Of control and Dependency Injection and really don't like the ServiceLocator due to number of facts: Harder to maintain implicit dependencies. Harder to test the code. Potential threading issues. Explicit dependency only on the ServiceLocator. The code becomes harder to understand. Need to register the ServiceLocator interfaces during the testing. But on the other side, with plain POCO objects, I do not see any other way of performing the validation like above without ServiceLocator and only using IoC/DI. So the question would be: is there any way to use DI/IoC for the situation described above? Thanks, Dmitriy.
