  • git push merge error, but git pull is already up-to-date. Tried reclone, same problem.

    - by Jasie
    I do: git commit . git push error: Entry 'file.php' not uptodate. Cannot merge. Then I do git pull Already up-to-date. What do I do? I just want to get the latest version from the remote copy, and overwrite anything on my local copy. Edit: I tried everything. I deleted my local repo, and git clone ssh://[email protected]/directory ... Checking out files: 100%, done. git status On branch master nothing to commit (working directory clean) All looks good, right? Pull just in case. git pull Already up-to-date. I make a one line change in a file to see if I can push it. git commit . [master 1e18af1] Rando change 1 files changed, 2 insertions(+), 0 deletions(-) git push Counting objects: 13, done. Delta compression using up to 2 threads. Compressing objects: 100% (6/6), done. Writing objects: 100% (7/7), 646 bytes, done.

  • [C#] Lock a file and avoid readings while it's writing

    - by vtortola
    Hi, My web application returns a file from the filesystem. These files are dynamic, so I have no way to know the names o how many of them will there be. When this file doesn't exist, the application creates it from the database. I want to avoid that two different threads recreate the same file at the same time, or that a thread try to return the file while other thread is creating it. So I want to lock a file till its recreation is complete, if other thread try to access it ... it will have to wait the file be unlocked. I've been reading about FileStream.Lock, but I have to know the file length and it won't prevent that other thread try to read the file, so it doesn't work for my particular case. I've been reading also about FileAccess.None, but it will throw an exception (which exception type?) if other thread/process try to access the file... so I should develop a "try again while is faulting" ... and I don't like too much that approach, although maybe there is not a better way. How could I archieve this? Kind regards.

  • mysql query to dynamically convert row data to columns

    - by Anirudh Goel
    I am working on a pivot table query. The schema is as follows Sno, Name, District The same name may appear in many districts eg take the sample data for example 1 Mike CA 2 Mike CA 3 Proctor JB 4 Luke MN 5 Luke MN 6 Mike CA 7 Mike LP 8 Proctor MN 9 Proctor JB 10 Proctor MN 11 Luke MN As you see i have a set of 4 distinct districts (CA, JB, MN, LP). Now i wanted to get the pivot table generated for it by mapping the name against districts Name CA JB MN LP Mike 3 0 0 1 Proctor 0 2 2 0 Luke 0 0 3 0 i wrote the following query for this select name,sum(if(District="CA",1,0)) as "CA",sum(if(District="JB",1,0)) as "JB",sum(if(District="MN",1,0)) as "MN",sum(if(District="LP",1,0)) as "LP" from district_details group by name However there is a possibility that the districts may increase, in that case i will have to manually edit the query again and add the new district to it. I want to know if there is a query which can dynamically take the names of distinct districts and run the above query. I know i can do it with a procedure and generating the script on the fly, is there any other method too? I ask so because the output of the query "select distinct(districts) from district_details" will return me a single column having district name on each row, which i will like to be transposed to the column.

  • Properly registering JavaScript and CSS in MVC 2 Editor Templates

    - by Jaxidian
    How do I properly register javascript blocks in an ASP.NET MVC 2 (RTM) Editor template? The specific scenario I'm in is that I want to use Dynarch JSCal2 DateTimePicker for my standard datetime picker, but this question is in general to any reusable javascript package. I have my template working properly now but it has my JS and CSS includes in my master page and I would rather only include these things if I actually need them: <link rel="stylesheet" type="text/css" href="../../Content/JSCal2-1.7/jscal2.css" /> <link rel="stylesheet" type="text/css" href="../../Content/JSCal2-1.7/border-radius.css" /> <script type="text/javascript" src="../../Scripts/JSCal2-1.7/jscal2.js"></script> <script type="text/javascript" src="../../Scripts/JSCal2-1.7/lang/en.js"></script> So obviously I could just put these lines into my template, but then if I have a screen that has 5 DateTimePickers, then this content would be duplicated 5 times which wouldn't be ideal. Anyways, I still want my View's Template to trigger this code being put into the <head> of my page. While it is completely unrelated to my asking this question, I thought I'd share my template on here (so far) in case it's useful in any way: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DateTime>" %> <%= Html.TextBoxFor(model => Model) %> <input type="button" id="<%= ViewData.TemplateInfo.GetFullHtmlFieldId("cal-trigger") %>" value="..." /> <script type="text/javascript"> var <%= ViewData.TemplateInfo.GetFullHtmlFieldId("cal") %> = Calendar.setup({ trigger : "<%= ViewData.TemplateInfo.GetFullHtmlFieldId(string.Empty) %>", inputField : "<%= ViewData.TemplateInfo.GetFullHtmlFieldId(string.Empty) %>", onSelect : function() { this.hide(); }, showTime : 12, selectionType : Calendar.SEL_SINGLE, dateFormat : '%o/%e/%Y %l:%M %P' }); </script>

  • Confusion about Kerberos, delegation and SPNs.

    - by Vilx-
    I'm trying to write a proof-of-concept application that performs Kerberos delegation. I've written all the code, and it seems to working (I'm authenticating fine), but the resulting security context doesn't have the ISC_REQ_DELEGATE flag set. So I'm thinking that maybe one of the endpoints (client or server) is forbidden to delegate. However I'm not authenticating against an SPN. Just one domain user against another domain user. As the SPN for InitializeSecurityContext() I'm passing "[email protected]" (which is the user account under which the server application is running). As I understand, domain users have delegation enabled by default. Anyway, I asked the admin to check, and the "account is sensitive and cannot be delegated" checkbox is off. I know that if my server was running as a NETWORK SERVICE and I used an SPN to connect to it, then I'd need the computer account in AD to have the "Trust computer for delegation" checkbox checked (off by default), but... this is not the case, right? Or is it? Also - when the checkbox in the computer account is set, do the changes take place immediately, or must I reboot the server PC or wait for a while?

  • Atomic UPSERT in SQL Server 2005

    - by rabidpebble
    What is the correct pattern for doing an atomic "UPSERT" (UPDATE where exists, INSERT otherwise) in SQL Server 2005? I see a lot of code on SO (e.g. see http://stackoverflow.com/questions/639854/tsql-check-if-a-row-exists-otherwise-insert) with the following two-part pattern: UPDATE ... FROM ... WHERE <condition> -- race condition risk here IF @@ROWCOUNT = 0 INSERT ... or IF (SELECT COUNT(*) FROM ... WHERE <condition>) = 0 -- race condition risk here INSERT ... ELSE UPDATE ... where will be an evaluation of natural keys. None of the above approaches seem to deal well with concurrency. If I cannot have two rows with the same natural key, it seems like all of the above risk inserting rows with the same natural keys in race condition scenarios. I have been using the following approach but I'm surprised not to see it anywhere in people's responses so I'm wondering what is wrong with it: INSERT INTO <table> SELECT <natural keys>, <other stuff...> FROM <table> WHERE NOT EXISTS -- race condition risk here? ( SELECT 1 FROM <table> WHERE <natural keys> ) UPDATE ... WHERE <natural keys> (Note: I'm assuming that rows will not be deleted from this table. Although it would be nice to discuss how to handle the case where they can be deleted -- are transactions the only option? Which level of isolation?) Is this atomic? I can't locate where this would be documented in SQL Server documentation.

  • Reloading an external element (via jQuery's .load) without impact on same-named host elements on sam

    - by Martin Pescador
    Hello together! [First, I'm an absolute beginner. I tried to express myself as good as I could - please correct me on any issue... Now: I have the following problem:] I am loading a div element, which class always is ".gallery" from a couple of pages (in this example "the page index.php?page=orange") into another page's div (in this case with the ID "orange") using the following code: $("#orange").load("http://example.com/index.php?page=orange .gallery"); Each div.gallery I load in, is a set of a few images. Between them, you can switch (there are "previous"- and "next"-links in ".imgnavi"). $(".imgnavi a").live("click", function(ev) { ev.preventDefault(); ev.stopPropagation(); $(".gallery").load($(this).attr("href")); return false; }) What happens now: Loading the different div.gallery into the new page is no problem, but as soon as I start to navigate inside those divs (each div is a little gallery, where you can switch between images), the div.gallery I am switching in is suddenly loaded into EVERY other div.gallery in the document! How do I prevent that?

  • Conversion constructor vs. conversion operator: precedence

    - by GRB
    Reading some questions here on SO about conversion operators and constructors got me thinking about the interaction between them, namely when there is an 'ambiguous' call. Consider the following code: class A; class B { public: B(){} B(const A&) //conversion constructor { cout << "called B's conversion constructor" << endl; } }; class A { public: operator B() //conversion operator { cout << "called A's conversion operator" << endl; return B(); } }; int main() { B b = A(); //what should be called here? apparently, A::operator B() return 0; } The above code displays "called A's conversion operator", meaning that the conversion operator is called as opposed to the constructor. If you remove/comment out the operator B() code from A, the compiler will happily switch over to using the constructor instead (with no other changes to the code). My questions are: Since the compiler doesn't consider B b = A(); to be an ambiguous call, there must be some type of precedence at work here. Where exactly is this precedence established? (a reference/quote from the C++ standard would be appreciated) From an object-oriented philosophical standpoint, is this the way the code should behave? Who knows more about how an A object should become a B object, A or B? According to C++, the answer is A -- is there anything in object-oriented practice that suggests this should be the case? To me personally, it would make sense either way, so I'm interested to know how the choice was made. Thanks in advance

  • How to detect if a Surface Contact is over a ScatterView?

    - by Bart Roozendaal
    This is a (kind of) similar situation as in the SDK Sample Shopping Cart for MS Surface. I have an application with two ScatterViews. The first covers the complete Surface window ('surface'). The second resides in a TagVisualization object ('pod'). There might be more than one pod available (if more than one tag is down on the table). I would like to be able to drag a ScatterViewItem from the 'pod' to the 'surface' or another 'pod'. I have no problems in detecting if a ScatterViewItem is leaving its ScatterView parent. Also, no problems in reparenting the ScatterViewItem. However, I want to detect which ScatterView the item is being dragged on. In the SDK Sample they have used a visual element (an ellipse in this case) which is below the ScatterViews. VisualTreeHelper.HitTest is used to determine if the contact is over the ellipse. If so, the 'connected' ScatterView is found. I don't think this is a very elegant solution. I wouldn't want a visual element put in there, just to detect if a contact is over a ScatterView. Are there betterwways to accomplish this kind of 'hittesting'? Thanks, Bart

  • eclipse tomcat debug mode slow - pegs cpu

    - by andersonbd1
    Running Tomcat through eclipse works fine in non-debug mode, but not in debug mode. When I try to start the Tomcat server in debug mode, the console output looks fine for a while, but then starts slowing down and eventually just stops, pegging the cpu at 100%. I don't think it's relevant, but just in case - here's the console output right about when it starts slowing down and eventually stopping (by stopping I mean no more console output, but still 100% cpu). 2009-09-02 14:35:30,859 INFO NONE org.springframework.context.weaving.DefaultContextLoadTimeWeaver:72 - Found Spring's JVM agent for instrumentation 2009-09-02 14:35:49,562 INFO NONE org.springframework.beans.factory.support.DefaultListableBeanFactory:414 - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@ed889d: defining beans [... 2009-09-02 14:37:31,031 INFO NONE org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean:221 - Building JPA container EntityManagerFactory for persistence unit ... I tried everything I could think of to fix it: cleanesd tomcat working directory restarted eclipse restarted Windows refreshed/cleaned all projects I first had this problem last week using eclipse ganymede. I had been running fine in debug-mode for several months prior to this issue. I didn't make any significant changes to our project that would cause this. Eventually, I upgraded to eclipse galileo which solved my problem. Now 2 days later, I'm having the same problem in galileo. Like I said it works fine in non-debug mode. Any help is much appreciated. I should add that other things work in debug mode - for instance junit tests, so it is something specific to tomcat.

  • Tricky CSS Layout

    - by Meep3D
    So I am making a website with quite a problematic layout. There are four corner images TL, TR, BL and BR indicated by black blocks. The dark orange area is the main content (to a width of 960px), with the outside area denoted by the green arrow as the browser window. See diagram: The top image represents the site at its narrowest possible - it shouldn't be allowed to be narrower than this (960px) if it is larger than the defined area there should be no scrollbars. The bottom two images represent different widths of browser. The bottom left and right black blocks (images) should be at the bottom left and right of the screen at all times, unless the width falls to 960px, in which case the BL and BR images should poke into the main area slightly. If the site is shrunk to, say 200px, the BR image should not still be poking in the right corner. At this point I don't really care about it working exactly in IE6 (I can get it roughly working) but I can't even figure out how to do it fully without Javascript or extremely experimental CSS. Currently I am using absolutely positioned div's which sort of work, but don't work quite right. I think I'd be willing to accept a bit of JS if there is no other way but I'd rather not. Answer very appreciated!

  • How can I install the BlackBerry v5.0.0 component pack into Eclipse?

    - by Dan J
    I'm trying to install the latest v5.0.0 "beta 2" BlackBerry OS Component Pack into Eclipse 3.4.2 with BlackBerry Eclipse plugin v1.0.0.67, but have hit a few problems. Has anybody found an easy way to do this? I had no trouble installing the v4.5.0 and v4.7.0 Component Packs. It's rather strange that BlackBerry are shipping new phones with the v5.0.0 OS installed (e.g. a Storm 2 9550 and Bold 9700 that I just bought), and pushing that update to phones whilst the BlackBerry website still considers the v5.0.0 SDK / Component Packs to be "beta 2"! If anybody knows when an official non-beta Component Pack is going to be released that might solve my problem... In case it helps, the problems I've hit so far are: -Contrary to the implication on the BlackBerry website, the Eclipse "Software Update..." option for the v5.0.0 Component Pack claims it only works on the v1.0.0 Eclipse BlackBerry plugin, not the new v1.1 one. -I then tried to install the v5.0.0 Component Pack through the "Software Updates..." menu in Eclipse using the v1.0.0 Eclipse BlackBery plugin. Once I'd done the 200MB download the install failed with a "Invalid zip file format" error. -I might just have been unlucky with a corrupted download but I did try it twice, once through "Software Updates..." and once by selecting "Archive" to install the downloaded Component Pack (which unlike v4.5.0 and v4.7.0 was a JAR, not a ZIP).

  • Improving long-polling Ajax performance

    - by Bears will eat you
    I'm writing a webapp (Firefox-compatible only) which uses long polling (via jQuery's ajax abilities) to send more-or-less constant updates from the server to the client. I'm concerned about the effects of leaving this running for long periods of time, say, all day or overnight. The basic code skeleton is this: function processResults(xml) { // do stuff with the xml from the server } function fetch() { setTimeout(function () { $.ajax({ type: 'GET', url: 'foo/bar/baz', dataType: 'xml', success: function (xml) { processResults(xml); fetch(); }, error: function (xhr, type, exception) { if (xhr.status === 0) { console.log('XMLHttpRequest cancelled'); } else { console.debug(xhr); fetch(); } } }); }, 500); } (The half-second "sleep" is so that the client doesn't hammer the server if the updates are coming back to the client quickly - which they usually are.) After leaving this running overnight, it tends to make Firefox crawl. I'd been thinking that this could be partially caused by a large stack depth since I've basically written an infinitely recursive function. However, if I use Firebug and throw a breakpoint into fetch, it looks like this is not the case. The stack that Firebug shows me is only about 4 or 5 frames deep, even after an hour. One of the solutions I'm considering is changing my recursive function to an iterative one, but I can't figure out how I would insert the delay in between Ajax requests without spinning. I've looked at the JS 1.7 "yield" keyword but I can't quite wrap my head around it, to figure out if it's what I need here. Is the best solution just to do a hard refresh on the page periodically, say, once every hour? Is there a better/leaner long-polling design pattern that won't put a hurt on the browser even after running for 8 or 12 hours? Or should I just skip the long polling altogether and use a different "constant update" pattern since I usually know how frequently the server will have a response for me?

  • Making Ninject Interceptors work with async methods

    - by captncraig
    I am starting to work with ninject interceptors to wrap some of my async code with various behaviors and am having some trouble getting everything working. Here is an interceptor I am working with: public class MyInterceptor : IInterceptor { public async void Intercept(IInvocation invocation) { try { invocation.Proceed(); //check that method indeed returns Task await (Task) invocation.ReturnValue; RecordSuccess(); } catch (Exception) { RecordError(); invocation.ReturnValue = _defaultValue; throw; } } This appears to run properly in most normal cases. I am not sure if this will do what I expect. Although it appears to return control flow to the caller asynchronously, I am still a bit worried about the possibility that the proxy is unintentionally blocking a thread or something. That aside, I cannot get the exception handling working. For this test case: [Test] public void ExceptionThrown() { try { var interceptor = new MyInterceptor(DefaultValue); var invocation = new Mock<IInvocation>(); invocation.Setup(x => x.Proceed()).Throws<InvalidOperationException>(); interceptor.Intercept(invocation.Object); } catch (Exception e) { } } I can see in the interceptor that the catch block is hit, but the catch block in my test is never hit from the rethrow. I am more confused because there is no proxy or anything here, just pretty simple mocks and objects. I also tried something like Task.Run(() => interceptor.Intercept(invocation.Object)).Wait(); in my test, and still no change. The test passes happily, but the nUnit output does have the exception message. I imagine I am messing something up, and I don't quite understand what is going on as much as I think I do. Is there a better way to intercept an async method? What am I doing wrong with regards to exception handling?

  • Version control of software refactoring

    - by Muhammad Alkarouri
    What is the best way of doing version control of large scale refactoring? My typical style of programming (actually of writing documents as well) is getting something out as quickly as possible and then refactoring it. Typically, refactoring takes place at the same time as adding other functionality. In addition to standard refactoring of classes and functions, functions may move from one file to another, files get split and merged or just reordered. For the time being, I am using version control as a lone user, so there is no issue of interaction with other developers at this stage. Still, version control gives me two aspects: Backup and ability to revert to a good version "in case". Looking at the history tells me how the project progressed and the flow of ideas. I am using mercurial on windows using TortoiseHg which enables selections of hunks to commit. The reason I mention this is that I would like advice on the granularity of a commit in refactoring. Should I split refactoring from functionality added always in committing? I have looked at the answers of http://stackoverflow.com/questions/68459/refactoring-and-source-control-how-to but it doesn't answer my question. That question focuses on collaboration with a team. This one concentrates on having a history that is understandable in future (assuming I don't rewrite history as some VCS seem to allow).

  • Safari flash wmode not working - anything wrong with this embed?

    - by hfidgen
    I've got a problem with this embed in Safari. It works just fine on all other browsers, IE6 included. The problem is that the embed seems to jump to the very top layer, ignoring all z-index or positioning statements. This is important, because several html design features are overlayed on the flash. This embed was written to work with swfobject, but still doesnt work when: swfobject disabled wmode = transparent/opaque/removed entirely Is this a problem with safari or the code? And if it's the code then what does safari do differently to all the other browsers? Bah. Thanks for any help ;) <object id="Flash_Banner" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="950" height="400" title=""> <param name="movie" value="ui.swf" /> <param name="quality" value="high" /> <param name="wmode" value="opaque" /> <!--[if !IE]>--> <object type="application/x-shockwave-flash" data="ui.swf" width="950" height="400" title=""> <param name="quality" value="high" /> <param name="wmode" value="opaque" /> <!--<![endif]--> <div id="banner_slider"><img src="images/banners/case.jpg" width="950" height="400" alt="" /></div> <!--[if !IE]>--> </object> <!--<![endif]--> </object>

  • Pause code execution until UIAlertView button is pressed?

    - by JuBu1324
    One of my methods sends a message to an object (what do you know about that), and expects a BOOL for an answer. However, BOOL answer it is expecting is based on the answer to a UIAlertView created in the receiving object's method. However, the code doesn't pause while waiting for the user to answer the UIAlertView. My problem is: how do I use -alertView:clickedButtonAtIndex in the method's return value? Here's the code the message runs (in this construction, I was expecting navigateAwayFromTab to change based on the user input in the UIAlertView, but it never gets a chance): - (BOOL)readyToNavigateAwayFromTab { NSLog( @"message received by Medical View"); navigateAwayFromTab = NO; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Navigate Away From Tab?" message:@"Navigating away from this tab will save your work." delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil ]; [alert show]; [alert release]; return navigateAwayFromTab; } #define CANCEL 0 #define OK 1 - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if( buttonIndex == OK ) navigateAwayFromTab = YES; } I've been reading up on the modal UIAlertView debate, and I agree with apple's implementation - at lest as the rule. However, in this case I don't see any way of solving the problem by putting code in -alertView:clickedButtonAtIndex because I don't need to run code based on the UIAlertView, I just need to read the response. Any suggestions on how I can reach my gaol? I've tried a while loop after [alert show] already, but then the alert doesn't even show then, and for a number of reasons I can't use -viewWillDisapear.

  • How do I deselect grid row when grouping in David Poll's silverlight CollectionPrinter

    - by kpg
    I'm using David Poll's CollectionPrinter and modifications by Fama to perform grouping. I'm using the control to print a datagrid with grouping and it works well if not a little slow. Problem: When the grid is displayed the first row of the grid is selected and the first cell of the row is also selected. I want to either deselect the row or change the datagrid template to make selected rows/cells appear as not selected. I tried to specify a grid template to change the row/cell selection appearance but when I added the default template I got a COM error of all things - anyway I concluded that what I was doing was not compatible with the SLab libraries, or perhaps because the grid was specified in a datatemplate. In any case I abandoned that approach. Since I have the SLab source if I understood it more there may be a way to deselect the row after from that side of things - but I know the SLaB CommectionPrinter does not rely on the data template to be a grid, so I'm not sure how to modify the code to accomplish what I want. Question: How can I prevent the row from being selected or deselect it once it is or change the appearance of the selectd row when using the CollectionPrinter with grouping? Note that the row selection problem may occur without grouping as well, I don;t know, but it definatly does with grouping.

  • C# PrintPreviewDialog Modification possible?

    - by C. Griffin
    Currently, what I'm doing is this: Using the built-in .NET PrintPreviewDialog Attaching my own Click handler to the Print button, which allows for the user to select the printer before finally printing. This all WORKS, HOWEVER, the OnprintToolStripButtonClick event is still sending the document to the default printer BEFORE the user gets to choose the actual printer and click Print (which works, but they're getting an extra copy on the default printer first from the old Handler). Can I remove this built-in Click handler? I've tried the other methods mentioned on here in regards to using an EventHandlerList to remove the handlers, but it doesn't work for the built-in printing event. Here is a copy of my current code in case it helps clarify: // ... Irrelevant code before this private PrintPreviewDialog ppdlg; ToolStrip ts = new ToolStrip(); ts.Name = "wrongToolStrip"; foreach (Control ctl in ppdlg.Controls) { if (ctl.Name.Equals("toolStrip1")) { ts = ctl as ToolStrip; break; } } ToolStripButton printButton = new ToolStripButton(); foreach (ToolStripItem tsi in ts.Items) { if (tsi.Name.Equals("printToolStripButton")) { printButton = tsi as ToolStripButton; } } printButton.Click += new EventHandler(this.SelectPrinterAfterPreview); // ... Irrelevant code afterwards omitted // Here is the Handler for choosing a Printer that gets called after the // PrintPreviewDialog's "Print" button is clicked. private void SelectPrinterAfterPreview(object sender, EventArgs e) { frmMainPage frmMain = (frmMainPage)this.MdiParent; if (frmMain.printDialog1.ShowDialog() == DialogResult.OK) { pd.PrinterSettings.PrinterName = frmMain.printDialog1.PrinterSettings.PrinterName; pd.PrinterSettings.Copies = frmMain.printDialog1.PrinterSettings.Copies; pd.Print(); } }

  • iPhone Keychain Questions

    - by AO
    Some questions: * Is there some way to view the data present in the iPhone keychain? * The items an application adds, cannot be accessed by any other application, can it? * What is the purpose of the identifier and access group in the initialization? My guess is that the identifier is simply used to find items but I'm a little bit unsure of the access group. If the access group is assigned nil, all applications can access the items? If the access group is assigned X, could the items be accessed by another application with the same string X as access group or what is the purpose of the access group in this case? * Is the data in the keychain removed when the application is removed? If not, how do I achieve that? And finally: I can't get the KeychainItemWrapper (Apple example) to work. I've added the KeychainItemWrapper files to my project and when running it on the phone, an exception is thrown by SecItemAdd, saying that one or more parameters were not valid (result code -50). The code triggering the SecItemAdd follows: KeychainItemWrapper* wrapper = [[KeychainItemWrapper alloc] initWithIdentifier:@"something" accessGroup:@"com.company.whatever"]; [wrapper setObject:@"this is my password" forKey:@"password"]; NSLog(@"Password: %@", [wrapper objectForKey:@"password"]); The code can be found at http://developer.apple.com/iphone/library/samplecode/GenericKeychain/index.html

  • WPF: disable inheritance of properties

    - by Maximilian Csuk
    Hi! I would like to use a TabControl as the main navigation in the application I am working on. So I would like to make the font in the headers of the TabItems bigger and also give it another background-color. However, I do not want this to be inherited. For example, if I use this code: <TabControl FontSize="18pt"> <TabItem Header="Tab 1"> <Button>Button 1</Button> </TabItem> </TabControl> The font in the button is also 18pt big. I know that this is normal dependency property behaviour because the property is inherited, but that's not what I want in this case. I would like to change the TabItems without changing anything in the children. Isn't that possible? Because re-setting all children to default values is a PITA. Thanks for your time.

  • UITextField in UIAlertView doesn't respond to cut/copy/paste on second showing

    - by Jesse Grosjean
    Edit Reposting... I accidentally marked my previous question as "commuity wiki" and didn't realize that answers to wiki posts don't generate reputation. I"m adding a UITextView to a UIAlertView with the following code: UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Enter Name Here" message:@"this gets covered!" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"OK!", nil]; UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)]; CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60); [alert setTransform:myTransform]; [myTextField setBackgroundColor:[UIColor whiteColor]]; [alert addSubview:myTextField]; [alert show]; [alert release]; [myTextField release]; If I place that code in a standard action method: (IBAction)testAlertView:(id)sender { ...the above code... } Then the first time I show the UIAlertView the cut/copy/paste popup menu will show in UITextField that's been added to the UIAlertView. (For instance if I tap and hold, then "Paste" will popup after I release. The problem is after working correctly the first time, none of the cut/copy/paste buttons will show up again next time I show the UIAlertView (new instance) unless I restart the app. Does anyone know why, or how to fix this problem? Bonus information I just found out that I can get things to always work if I create an show the alert within a UIActionSheet delagate callback. For instance this always works (cut/copy/paste always shows up when in the UITextField when appropriate) (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { ...the above code... } Any idea what might be happening in this second case that make things work? I don't want to use a UIActionSheet in my app, so I'd like to find a way to make it work from a plain old action method. Thanks, Jesse

  • Perf: Viewing thousands of images in Silverlight 3 on a 3D Wall

    - by Bob Holland
    I currently work on a very cool Silverlight app that displays photos in a 3D wall space like the Wall3D demo that is thrown in with Blend 3. The problem I am currently facing is performance. The app works like this: As you scroll right or left the 3d photo wall rotates As each movement is made, the next column of photos are downloaded, decoded into a BitmapImage and thrown into a 3D Wall Node. As you can imagine users (if you let them) will want to flip through the photos really quickly, but the problem I have is I cannot display the photos quick enough. In most cases it's a beautiful app that works really well, but when an album contains over 300 photos, you can imagine the sort of memory taken up by all the BitmapImage classes and how moving the slider can jump from photo 20 to photo 120 in a second. Of course we have algorithms in place to not download every photo in between, but I still can't work out a fast way to get the photos displayed. It may be a case that we need to throw away the 'great for show' 3D wall and go to a flat DeepZoom like wall like the Playboy archive one that Vertigo did. Still not sure, let me know your thoughts. P.S. We are using Kit3D for all the 3D work, it's using PerspectiveCamera, Model3DGroup, ModelVisual3D, RotateTransform3D & TranslateTransform3D. Cheers, Bob.
