  • Bug in UITableView: Why is the section header covered by an row after deleting an row?

    - by mystify
    When I delete a row like this, and then scroll a little bit, one of the rows of that section happens to cover the section header. - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [dataManager deleteValueAtIndex:indexPath.row]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; } } Is there any solution to this?

  • How can I track the last location of a shipment effeciently using latest date of reporting?

    - by hash
    I need to find the latest location of each cargo item in a consignment. We mostly do this by looking at the route selected for a consignment and then finding the latest (max) time entered against nodes of this route. For example if a route has 5 nodes and we have entered timings against first 3 nodes, then the latest timing (max time) will tell us its location among the 3 nodes. I am really stuck on this query regarding performance issues. Even on few hundred rows, it takes more than 2 minutes. Please suggest how can I improve this query or any alternative approach I should acquire? Note: ATA= Actual Time of Arrival and ATD = Actual Time of Departure SELECT DISTINCT(c.id) as cid,c.ref as cons_ref , c.Name, c.CustRef FROM consignments c INNER JOIN routes r ON c.Route = r.ID INNER JOIN routes_nodes rn ON rn.Route = r.ID INNER JOIN cargo_timing ct ON c.ID=ct.ConsignmentID INNER JOIN (SELECT t.ConsignmentID, Max(t.firstata) as MaxDate FROM cargo_timing t GROUP BY t.ConsignmentID ) as TMax ON TMax.MaxDate=ct.firstata AND TMax.ConsignmentID=c.ID INNER JOIN nodes an ON ct.routenodeid = an.ID INNER JOIN contract cor ON cor.ID = c.Contract WHERE c.Type = 'Road' AND ( c.ATD = 0 AND c.ATA != 0 ) AND (cor.contract_reference in ('Generic','BP001','020-543-912')) ORDER BY c.ref ASC

  • Proprietary AMD driver freezes my Ideapad

    - by mote
    I got this problem that I can't figure out what to do about. On Ideapad s205 with Ubuntu 12.04* (64), if I install Catalyst Centre 12.1 or newer it Freeze (lock's up), 1-3 times a day. It doesn't suffer freezing when using Radeon driver, but Radeon driver are considerably slower and flickers, so I would really prefer the proprietary driver (with no freezing). I reported the bug to launchpad but it doesn't get attention. -Also tried Ubuntu forums. Reported bug to AMD bug site "http://ati.cchtml.com/", but I don't think anybody reads it. Wrote AMD support several times, but get silly answers like "reinstall Windows". -Asked them to send the bug to Linux driver developers, but never heard a thing (more than once). The same nothing happens when writing to the feedback link from AMD driver download site. I'm so frustrated here, any advice would help. Thanks (*The same on Ubuntu 11.10)

  • Why is the colspan not working properly in this script? js bug or IE ?

    - by Perpetualcoder
    This question is related to this question I asked a little while back. The updated code is posted here. This to note is that i am looking to create a HTML table dynamically that looks similar to this: <table> <tbody> <tr> <td colspan="3" align="right">Header</td> </tr> <tr> <td colspan="3" align="right">Header</td> </tr> <tr> <td colspan="3" align="right">Header</td> </tr> <tr> <td>Col1</td> <td>Col3</td> <td>Col4</td> </tr> <tr> <td>Col1</td> <td>Col3</td> <td>Col4</td> </tr> </tbody> </table> I can get this done in markup but when I do it in js the colspan does not seem to work in IE7. Any hep will be greatly appreciated.

  • ValidateInputAttribute bug in VS 2010 RC / ASP.NET MVC 2.0?

    - by Ben
    Am I doing something wrong here? I have a text area on a view and am posting back the html contents. In VS 2008 and MVC 1.0 the following code successfully prevents input validation: [HttpPost] [ValidateInput(false)] public ActionResult Index(int? id) { return View(); } If I execute this code in VS 2010 / MVC 2.0 I always get this error: A potentially dangerous Request.Form value was detected from the client (body=""). Any ideas?

  • Testing To Prevent Cascading Bugs

    - by jfrankcarr
    Yesterday, Twitter was hit with a "Cascading Bug" as described in this blog post: A “cascading bug” is a bug with an effect that isn’t confined to a particular software element, but rather its effect “cascades” into other elements as well. I've seen this kind of bug, on a smaller scale of course, on some projects I've worked on. They can be difficult to identify in dev/test environments, even within a test driven development environment. My questions are... What are some strategies you use, beyond the basic TDD and standard regression testing, to identify and prevent the potential trouble points that might only occur in the production environment? Does the presence of such problems indicate a breakdown in the software development process or simply a by-product of complex software systems?

  • IE Display bug - solved when using the "developer tools"?

    - by nute
    I have some Javascript/CSS issues with IE (no suprises?). So when I see the error in IE8, I go to Tools Developer Tools. Then I navigate to the correct DIV. I click on it, look around ... then I look again at my page, and the problem is fixed! This makes debugging pretty difficult... To see the display error, go to http://www.makemeheal.com/mmh/home.do in IE, and look at the "Your Recent History" module.

  • code throws std::bad_alloc, not enough memory or can it be a bug?

    - by Andreas
    I am parsing using a pretty large grammar (1.1 GB, it's data-oriented parsing). The parser I use (bitpar) is said to be optimized for highly ambiguous grammars. I'm getting this error: 1terminate called after throwing an instance of 'std::bad_alloc' what(): St9bad_alloc dotest.sh: line 11: 16686 Aborted bitpar -p -b 1 -s top -u unknownwordsm -w pos.dfsa /tmp/gsyntax.pcfg /tmp/gsyntax.lex arbobanko.test arbobanko.results Is there hope? Does it mean that it has ran out of memory? It uses about 15 GB before it crashes. The machine I'm using has 32 GB of RAM, plus swap as well. It crashes before outputting a single parse tree. The parser is an efficient CYK chart parser using bit vector representations; I presume it is already near the limit of memory efficiency. If it really requires too much memory I could sample from the grammar rules, but this will decrease parse accuracy of course.

  • InvalidProgramException Running Unit Test

    - by Anthony Trudeau
    There is a bug in the unit testing framework in Visual Studio 2010 with unit testing.  The bug appears in a very special circumstance involving an internal generic type. The bug causes the following exception to be thrown: System.InvalidProgramException: JIT Compiler encountered an internal limitation. This occurs under the following circumstances: Type being tested is internal or private Method being tested is generic  Method being tested has an out parameter Type accessor functionality used to access the internal type The exception is not thrown if the InternalsVisibleToAttribute is assigned to the source assembly and the accessor type is not used; nor is it thrown if the method is not a generic method. Bug #635093 has been added through Microsoft Connect

  • How do I create a SQL Server 2008 Reporting Services Template to a Default Font?

    - by David Stein
    I'm creating a new template to create reports from at a later date. I know how to create one, and I know where to save it. However, the problem is this. Everything that is created on the report uses the default font of Arial with a size of 10pt. I need to set mine to default to Tahoma 11pt. I can create a mock title, mock tables, etc and save those to Tahoma 11pt, but any new controls that are used on any version of this report will default back to Arial 10pt. How do I fix this?

  • How to push oath token to LocalStorage or LocalSession and listen to the Storage Event? (SoundCloud Php/JS bug workaround)

    - by afxjzs
    This references this issue: Javascript SDK connect() function not working in chrome I asked for more information on how to resolve with localstorage and was asked to create a new topic. The answer was "A workaround is instead of using window.opener, push the oauth token into LocalStorage or SessionStorage and have the opener window listen to the Storage event." but i have no idea how to do that. It seems really simple, but i don't know where to start. I couldn't find an relevant examples. thanks for your help!

  • is there such a thing as xsl:fo reporting or xsl:fo simulation?

    - by topmulch
    Hi, I am trying to determine if MY xsl:fo generated PDF file will exceed one page or not, without actually generating the output. We use Apache-FOP 0.95 on our server, and the XML data is being generated using a PHP DOMDocument class before being passed onto an XSL-FO template. My question: Are there PHP libraries out there that can simulate xsl:fo output and send me reports that I can use in my application? Alternatively, is there a way for the Apache FOP itself (or sibling Java app) that sends reports without actually generating a file? I have been reading the FOP documentation, and aside from some things I can not fully understand, I have not been able to find a way to do that from within FOP. Any advice is much appreciated.

  • How to plan/manage multi-platform (mobile) products?

    - by PhD
    Say I've to develop an app that runs on iOS, Android and Windows 8 Mobile. Now all three platforms are technically in different program languages. The only 'reuse' that I can see is that of the boxes-and-lines drawings (UML :) charts and nothing else. So how do companies/programmers manage the variation of the same product across different platforms especially since the implementation languages differ? It's 'easier' in the desktop world IMO given the plethora of languages and cross-platform libraries to make your life easier. Not so in the mobile world. More so, product line management principles don't seem to be all that applicable - what is same and variant doesn't really matter - the application is the same (conceptually) and the implementation is variant. Some difficulties that come to mind: Bug Fixing: Applications maybe designed in a similar manner but the bug identification and fixing would be radically different. A bug on iOS may/may-not be existent for that on Android. Or a bug fix approach on one platform may not be the same on another (unless it's a semantic bug like a!=b instead of a==b which would require the same 'approach' to fixing in essence Enhancements: Making a change on one platform would be radically different than on another Code-Design Divergence: They way the code is written/organized, the class structures etc., could be very different given the different implementation environments - leading to further reuse of the (above) UML models. There are of course many others - just keeping the development in sync and making sure all applications are up to the same version with the same set of features etc. Seems the effort is 3x that of a single application. So how exactly does one manage this nightmarish situation? Some thoughts: Split application to client/server to minimize the effect to client side only (not always doable) Use frameworks like Unity-3D that could take care of the cross-platform problem (mostly applicable to games and probably not to other applications etc.) Any other ways of managing a platform line? What are some proven approaches to managing/taming the effects?

  • Rails syntax for comments in templates: is this bug understood?

    - by brahn
    Using rails 2.3.2 I have a partial _foo.rhtml that begins with a comment as follows: <% # here is a comment %> <li><%= foo %></li> When I render the partial from a view in the traditional way, e.g. <% some_numbers = [1, 2, 3, 4, 5] %> <ul> <%= render :partial => "foo", :collection => some_numbers %> </ul> I found that the <li> and </li> tags are ommitted in the output -- i.e. the resulting HTML is <ul> 1 2 3 4 5 </ul> However, I can solve this problem by fixing _foo.rhtml to eliminate the space between the <% and the # so that the partial now reads: <%# here is a comment %> <li><%= foo %></li> My question: what's going on here? E.g., is <% # comment %> simply incorrect syntax for including comments in a template? Or is the problem more subtle? Thanks!

  • Does Microsoft hate firefox? ASP.Net gridview performance in firefox bug?

    - by Maxim Gershkovich
    Could someone please explain the significant difference in speed between a firefox updatepanel async postback and one performed in IE? Average Firefox Postback Time For 500 objects: 1.183 Second Average IE Postback Time For 500 objects: 0.295 Seconds Using firebug I can see that the majority of this time in FireFox is spent on the server side. A total of 1.04 seconds. Given this fact the only thing I can assume is causing this problem is the way that ASP.Net renders its controls between the two browsers. Has anyone run into this problem before? VB.Net Code Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click GridView1.DataBind() End Sub Public Function GetStockList() As StockList Dim res As New StockList For l = 0 To 500 Dim x As New Stock With {.Description = "test", .ID = Guid.NewGuid} res.Add(x) Next Return res End Function Public Class Stock Private m_ID As Guid Private m_Description As String Public Sub New() End Sub Public Property ID() As Guid Get Return Me.m_ID End Get Set(ByVal value As Guid) Me.m_ID = value End Set End Property Public Property Description() As String Get Return Me.m_Description End Get Set(ByVal value As String) Me.m_Description = value End Set End Property End Class Public Class StockList Inherits List(Of Stock) End Class Markup <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <script type="text/javascript" language="Javascript"> function timestamp_class(this_current_time, this_start_time, this_end_time, this_time_difference) { this.this_current_time = this_current_time; this.this_start_time = this_start_time; this.this_end_time = this_end_time; this.this_time_difference = this_time_difference; this.GetCurrentTime = GetCurrentTime; this.StartTiming = StartTiming; this.EndTiming = EndTiming; } //Get current time from date timestamp function GetCurrentTime() { var my_current_timestamp; my_current_timestamp = new Date(); //stamp current date & time return my_current_timestamp.getTime(); } //Stamp current time as start time and reset display textbox function StartTiming() { this.this_start_time = GetCurrentTime(); //stamp current time } //Stamp current time as stop time, compute elapsed time difference and display in textbox function EndTiming() { this.this_end_time = GetCurrentTime(); //stamp current time this.this_time_difference = (this.this_end_time - this.this_start_time) / 1000; //compute elapsed time return this.this_time_difference; } //--> </script> <script type="text/javascript" language="javascript"> var time_object = new timestamp_class(0, 0, 0, 0); //create new time object and initialize it Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); function BeginRequestHandler(sender, args) { var elem = args.get_postBackElement(); ActivateAlertDiv('visible', 'divAsyncRequestTimer', elem.value + ''); time_object.StartTiming(); } function EndRequestHandler(sender, args) { ActivateAlertDiv('visible', 'divAsyncRequestTimer', '(' + time_object.EndTiming() + ' Seconds)'); } function ActivateAlertDiv(visstring, elem, msg) { var adiv = $get(elem); adiv.style.visibility = visstring; adiv.innerHTML = msg; } </script> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <Triggers> <asp:AsyncPostBackTrigger ControlID="Button1" EventName="click" /> </Triggers> <ContentTemplate> <asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1"> </asp:UpdateProgress> <asp:Button ID="Button1" runat="server" Text="Button" /> <div id="divAsyncRequestTimer" style="font-size:small;"> </div> <asp:GridView ID="GridView1" runat="server" DataSourceID="ObjectDataSource1" AutoGenerateColumns="False"> <Columns> <asp:BoundField DataField="ID" HeaderText="ID" SortExpression="ID" /> <asp:BoundField DataField="Description" HeaderText="Description" SortExpression="Description" /> </Columns> </asp:GridView> <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetStockList" TypeName="WebApplication1._Default"> </asp:ObjectDataSource> </ContentTemplate> </asp:UpdatePanel> </form>

    I have made a small ASP.NET website. It uses sqlcachedependency The SQL Server Service Broker for the current database is not enabled, and as a result query notifications are not supported. Please enable the Service Broker for this database if you wish to use notifications. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: The SQL Server Service Broker for the current database is not enabled, and as a result query notifications are not supported. Please enable the Service Broker for this database if you wish to use notifications. Source Error: Line 12: System.Data.SqlClient.SqlDependency.Start(connString); This is the erroneous line in my global.asax. However, in sql server (2005), I enabled service broker like so (I connect and run the SQL Server service when I debug my site): ALTER DATABASE mynewdatabase SET ENABLE_BROKER with rollback immediate And this was successful. What am I missing? I am trying to use sql caching dependency and have followed all procedures. Thanks

    I copied some text from NSDate Reference as below, please check Return Value, it is said the format will be in YYYY-MM-DD HH:MM:SS ±HHMM, but I got as below in my app, so the reference is mistake? or code in mistake? Saturday, January 1, 2011 12:00:00 AM Japan Standard Time or 2011?1?1????0?00?00? ????? descriptionWithLocale: Returns a string representation of the receiver using the given locale. - (NSString *)descriptionWithLocale:(id)locale Parameters locale An NSLocale object. If you pass nil, NSDate formats the date in the same way as the description method. On Mac OS X v10.4 and earlier, this parameter was an NSDictionary object. If you pass in an NSDictionary object on Mac OS X v10.5, NSDate uses the default user locale—the same as if you passed in [NSLocale currentLocale]. Return Value A string representation of the receiver, using the given locale, or if the locale argument is nil, in the international format YYYY-MM-DD HH:MM:SS ±HHMM, where ±HHMM represents the time zone offset in hours and minutes from GMT (for example, “2001-03-24 10:45:32 +0600”)

  • How to manage maintenance/bug-fix branches in Subversion when third-party installers are involved?

    - by Mike Spross
    We have a suite of related products written in VB6, with some C# and VB.NET projects, and all the source is kept in a single Subversion repository. We haven't been using branches in Subversion (although we do tag releases now), and simply do all development in trunk, creating new releases when the trunk is stable enough. This causes no end of grief when we release a new version, issues are found with it, and we have already begun working on new features or major changes to the trunk. In the past, we would address this in one of two ways, depending on the severity of the issues and how stable we thought the trunk was: Hurry to stabilize the trunk, fix the issues, and then release a maintenance update based on the HEAD revision, but this had the side effect of releases that fixed the bugs but introduced new issues because of half-finished features or bugfixes that were in trunk. Make customers wait until the next official release, which is usually a few months. We want to change our policies to better deal with this situation. I was considering creating a "maintenance branch" in Subversion whenever I tag an official release. Then, new development would continue in trunk, and I can periodically merge specific fixes from trunk into the maintenance branch, and create a maintenance release when enough fixes are accumulated, while we continue to work on the next major update in parallel. I know we could also have a more stable trunk and create a branch for new updates instead, but keeping current development in trunk seems simpler to me. The major problem is that while we can easily branch the source code from a release tag and recompile it to get the binaries for that release, I'm not sure how to handle the setup and installer projects. We use QSetup to create all of our setup programs, and right now when we need to modify a setup project, we just edit the project file in-place (all the setup projects and any dependencies that we don't compile ourselves are stored on a separate server, and we make sure to always compile the setup projects on that machine only). However, since we may add or remove files to the setup as our code changes, there is no guarantee that today's setup projects will work with yesterday's source code. I was going to put all the QSetup projects in Subversion to deal with this, but I see some problems with this approach. I want the creation of setup programs to be as automated as possible, and at the very least, I want a separate build machine where I can build the release that I want (grabbing the code from Subversion first), grab the setup project for that release from Subversion, recompile the setup, and then copy the setup to another place on the network for QA testing and eventual release to customers. However, when someone needs to change a setup project (to add a new dependency that trunk now requires or to make other changes), there is a problem. If they treat it like a source file and check it out on their own machine to edit it, they won't be able to add files to the project unless they first copy the files they need to add to the build machine (so they are available to other developers), then copy all the other dependencies from the build machine to their machine, making sure to match the folder structure exactly. The issue here is that QSetup uses absolute paths for any files added to a setup project. However, this means installing a bunch of setup dependencies onto development machines, which seems messy (and which could destabilize the development environment if someone accidentally runs the setup project on their machine). Also, how do we manage third-party dependencies? For example, if the current maintenance branch used MSXML 3.0 and the trunk now requires MSXML 4.0, we can't go back and create a maintenance release if we have already replaced the MSXML library on the build machine with the latest version (assuming both versions have the same filename). The only solution I can think is to either put all the third-party dependencies in Subversion along with the source code, or to make sure we put different library versions in separate folders (i.e. C:\Setup\Dependencies\MSXML\v3.0 and C:\Setup\Dependencies\MSXML\v4.0). Is one way "better" or more common than the other? Are there any best practices for dealing with this situation? Basically, if we release v2.0 of our software, we want to be able to release v2.0.1, v2.0.2, and v.2.0.3 while we work on v2.1, but the whole setup/installation project and setup dependency issue is making this more complicated than the the typical "just create a branch in Subversion and recompile as needed" answer.

  • Sql server management studio reporting "The semaphore timeout period has expired."

    - by nis-simonsen
    On our development sql server, executing any query containing more than approximately 700 characters stalls for about 10 seconds and then reports the following error: Msg 121, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) for example, this query select * from FooTable where id = ' (.. and then 700 spaces ..) ' fails fails with the timeout error while this one select * from FooTable where id = ' (.. and then 600 spaces ..) ' fails with the expected Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier. - immediately. Indeed, throwing any query, including random garbage at our dev sql server exhibits this behaviour, while any other sql server I have available acts as expected, so I would think that the query never actually gets to parsing on the server. I'm at a loss here - any hints?
