  • MS Access 2003: Can data disappear from records and how do I test for this and prevent it?

    - by user328960
    Problem and about the database: Data from a record in Access 2003 database has disappeared. This database has 1 backend and 3 frontends, multiple users and is hosted on Citrix. Within this database, we have records of all clients served, ranging in the 1000s. Background info: The form for client data entry is set up with various subforms, including both a "programs enrolled" subform and a "services" subform. A client can be enrolled in multiple programs. Once enrolled in a program, services can be entered for that program area using the services subform. There are multiple fields in the services subform, one of which is a drop-down field allowing you to choose from the programs a client has been enrolled in (the list is updated for that client whenever he is enrolled in a new program). The problem details: For one specific record and one specific program area, the program has disappeared from the "programs enrolled" subform and all of the related services have disappeared from the "services" subform for a period of 3 months of data entry. However, other programs and services for this record did not disappear. Questions: Is the disappearance of data a common Access 2003 problem? Are there tests in place that can be run to see if data is disappearing and catch that data? If so, what are they? If there is specific code involved, what is it? What can be done to prevent the disappearing of data (other than using a different database)?

  • "If not exists" fails on SQL CE

    - by Mark Evans
    Hi I've got an unexpected problem. I'm making a script to update the schema on a SQL CE database. This won't run: if not exists ( Select column_name from information_schema.columns where column_name = 'TempTestField' and table_name = 'Inventory_Master_File' ) Alter table Inventory_Master_File add TempTestField nvarchar(10) null I think this is because I'm using stuff that isn't supported in SQL CE. Anyone know how to do this? I've tried rearranging the script and can't get anything to work. I tried "alter table ... where not exists ...". Note that the "select" part runs fine and also the "alter" part. The problem is "if not exists". I know there are some other postings regarding problems like this using SQL CE but I couldn't find an answer to this particular problem. Cheers Mark UPDATE: I've spent over an hour looking for a solution. I've found many postings asking for help with similar problems but I've still got no idea how to fix it. I really don't want to do this in C# code. I need to do this in a SQL script. I can't believe something this basic is causing so much difficulty :(

  • Using Windows and MMSystem in Delphi

    - by Jose Martinez
    Hi I am making a program to open and close the cd reader in which I have thought to write data to CD, the problem is the basis of the problem, which use "uses Windows 'and' uses MMSystem" but the problem is that when I use both at the same time being "uses Windows, MMSystem" gives an error and the program does not compile, I am using Delphi 2010, the strange thing is that when I use only one either Windows or MMSystem works fine and compiles. The error when I try to compile is: 'Could not find program' The code in question is this: mciSendString ('Set cdaudio door open wait', nil, 0, handle); I have two things to ask you first is how I avoid the error when using the two (Windows and MMSystem) and the other question was if he could open the CD player without using MMSystem, bone using Windows API, but not where to start The source : program Project1; {$APPTYPE CONSOLE} uses SysUtils,Windows,MMSystem; procedure opencd; begin mciSendString('Set cdaudio door open wait', nil, 0, 0); end; begin try Writeln('test'); except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end.

  • StackOverflow in VB.NET SQLite query

    - by Majgel
    I have an StackOverflowException in one of my DB functions that I don't know how to deal with. I have a SQLite database with one table "tblEmployees" that holds records for each employees (several thousand posts) and usually this function runs without any problem. But sometimes after the the function is called a thousand times it breaks with an StackOverflowException at the line "ReturnTable.Load(reader)" with the message: An unhandled exception of type 'System.StackOverflowException' occurred in System.Data.SQLite.dll If I restart the application it has no problem to continue with the exact same post it last crashed on. I can also make the exactly same DB-call from SQLite Admin at the crash time without no problems. Here is the code: Public Function GetNextEmployeeInQueue() As String Dim NextEmployeeInQueue As String = Nothing Dim query As [String] = "SELECT FirstName FROM tblEmployees WHERE Checked=0 LIMIT 1;" Try Dim ReturnTable As New DataTable() Dim mycommand As New SQLiteCommand(cnn) mycommand.CommandText = query Dim reader As SQLiteDataReader = mycommand.ExecuteReader() ReturnTable.Load(reader) reader.Close() If ReturnTable.Rows.Count > 0 Then NextEmployeeInQueue = ReturnTable.Rows(0)("FirstName").ToString() Else MsgBox("No more employees found in queue") End If Catch fail As Exception MessageBox.Show("Error: " & fail.Message.ToString()) End Try If NextEmployeeInQueue IsNot Nothing Then Return NextEmployeeInQueue Else Return "No more records in queue" End If End Function When crashes, the reader has "Property evaluation failed." in all values. I assume there is some problem with allocated memory that isn't released correctly, but can't figure out what object it's all about. The DB-connection opens when the DB-class object is created and closes on main form Dispose. Should I maybe dispose the mycommand object every time in a finally block? But wouldn't that result in a closed DB-connection?

  • Jquery.Cycle and IE7 including next Div

    - by Aklobem
    Hi All, I'd really appreciate if someone could help me with a strange problem with Jquery.cycle. I've added jquery.cycle (verson 2.72) into a existing application (Prestashop) to slideshow a number of images. On Firefox, Mozilla etc it works brilliantly - on IE7 a bizarre problem occurs. The problem is where I have a and say 6 pictures a couple of to break things up then another content and IE includes the "editorial" into the slideshow. The "editorial" block is removed from the page, and appears as the last slide in the slideshow, located in the top left corner. Additional facts: jquery-1.2.6 is in use for the rest of the application (I've tried to upgrade it and all I get is the same behaviour with lots of other things breaking). I've tried jquery.cycle.lite - same behaviour. css: root { display: block; } .pics { height: 432px; width: 432px; padding: 0; margin: 0; } .pics img { padding: 15px; border: 1px solid #ccc; background-color: #eee; width: 400px; height: 400px; top: 0; left: 0 } div.pics { margin-left: auto; margin-right: auto; } snippet: $(document).ready(function() { $('.pics').cycle({ fx: 'fade', pause: 100, cleartype: 1 }); }); img source img source img source img source

  • Creating ViewResults outside of Controllers in ASP.NET MVC

    - by Craig Walker
    Several of my controller actions have a standard set of failure-handling behavior. In general, I want to: Load an object based on the Route Data (IDs and the like) If the Route Data does not point to a valid object (ex: through URL hacking) then inform the user of the problem and return an HTTP 404 Not Found Validate that the current user has the proper permissions on the object If the user doesn't have permission, inform the user of the problem and return an HTTP 403 Forbidden If the above is successful, then do something with that object that's action-specific (ie: render it in a view). These steps are so standardized that I want to have reusable code to implement the behavior. My current plan of attack was to have a helper method to do something like this: public static ActionResult HandleMyObject(this Controller controller, Func<MyObject,ActionResult> onSuccess) { var myObject = MyObject.LoadFrom(controller.RouteData). if ( myObject == null ) return NotFound(controller); if ( myObject.IsNotAllowed(controller.User)) return NotAllowed(controller); return onSuccess(myObject); } # NotAllowed() is pretty much the same as this public static NotFound(Controller controller){ controller.HttpContext.Response.StatusCode = 404 # NotFound.aspx is a shared view. ViewResult result = controller.View("NotFound"); return result; } The problem here is that Controller.View() is a protected method and so is not accessible from a helper. I've looked at creating a new ViewResult instance explicitly, but there's enough properties to set that I'm wary about doing so without knowing the pitfalls first. What's the best way to create a ViewResult from outside a particular Controller?

  • Using .NET's HttpWebRequest to download a multitude of files in a row

    - by Cornelius
    I have an application that needs to download several files in a row in succession (sometimes a few thousand). However, what ends up happening when several files need to be downloaded is I get an exception with an inner exception of type SocketException and the error code 10048 (WSAEADDRINUSE). I did some digging and basically it's because the server has run out of sockets (and they are all waiting for 240s or so before they become available again) - not coincidentally it starts happening around the 1024 file range. I would expect that the HttpWebRequest/ServicePointManager would be reusing my connection, but apparently it is not (and the files are https, so that may be part of it). I never saw this problem in the C++ code that this was ported from (but that doesn't mean it didn't ever happen - I'd be surprised if it was, though). I am properly closing the WebRequest object and the HttpWebRequest object has KeepAlive set to true by default. Next my intent is to fiddle around with ServicePointManager.SetTcpKeepAlive(). However, I can't see how more people haven't run into this problem. Has anyone else run into the problem, and if so, what did you do to get around it? Currently I have a retry scheme that detects this error and waits it out, but that doesn't seem like the right thing to do. Here's some basic code to verify what I'm doing (just in case I'm missing closing something): WebRequest webRequest = WebRequest.Create(uri); webRequest.Method = "GET"; webRequest.Credentials = new NetworkCredential(username, password); WebResponse webResponse = webRequest.GetResponse(); try { using(Stream stream = webResponse.GetResponseStream()) { // read the stream } } finally { webResponse.Close() }

  • 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.

  • How do I locate the CGRect for a substring of text in a UILabel?

    - by bryanjclark
    For a given NSRange, I'd like to find a CGRect in a UILabel that corresponds to the glyphs of that NSRange. For example, I'd like to find the CGRect that contains the word "dog" in the sentence "The quick brown fox jumps over the lazy dog." The trick is, the UILabel has multiple lines, and the text is really attributedText, so it's a bit tough to find the exact position of the string. The method that I'd like to write on my UILabel subclass would look something like this: - (CGRect)rectForSubstringWithRange:(NSRange)range; Details, for those who are interested: My goal with this is to be able to create a new UILabel with the exact appearance and position of the UILabel, that I can then animate. I've got the rest figured out, but it's this step in particular that's holding me back at the moment. What I've done to try and solve the issue so far: I'd hoped that with iOS 7, there'd be a bit of Text Kit that would solve this problem, but most every example I've seen with Text Kit focuses on UITextView and UITextField, rather than UILabel. I've seen another question on Stack Overflow here that promises to solve the problem, but the accepted answer is over two years old, and the code doesn't perform well with attributed text. I'd bet that the right answer to this involves one of the following: Using a standard Text Kit method to solve this problem in a single line of code. I'd bet it would involve NSLayoutManager and textContainerForGlyphAtIndex:effectiveRange Writing a complex method that breaks the UILabel into lines, and finds the rect of a glyph within a line, likely using Core Text methods. My current best bet is to take apart @mattt's excellent TTTAttributedLabel, which has a method that finds a glyph at a point - if I invert that, and find the point for a glyph, that might work. Update: Here's a github gist with the three things I've tried so far to solve this issue: https://gist.github.com/bryanjclark/7036101

  • 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>

  • Design Patterns Recommendation for Filtering Option

    - by Tarik
    Hi people, I am thinking to create a filter object which filters and delete everything like html tags from a context. But I want it to be independent which means the design pattern I can apply will help me to add more filters in the future without effecting the current codes. I thought Abstract Factory but it seems it ain't gonna work out the way I want. So maybe builder but it looks same. I don't know I am kinda confused, some one please recommend me a design pattern which can solve my problem but before that let me elaborate the problem a little bit. Lets say I have a class which has Description field or property what ever. And I need filters which remove the things I want from this Description property. So whenever I apply the filter I can add more filter in underlying tier. So instead of re-touching the Description field, I can easily add more filters and all the filters will run for Description field and delete whatever they are supposed to delete from the Description context. I hope I could describe my problem. I think some of you ran into the same situation before. Thanks in advance...

  • Why is the UpdatePanel Response size changing on alternate requests?

    - by Decker
    We are using UpdatePanel in a small portion of a large page and have noticed a performance problem where IE7 becomes CPU bound and the control within the UpdatePanel takes a long time (upwards of 30 seconds) to render. We also noticed that Firefox does not seem to suffer from these delays. We ran both Fiddler (for IE) and Firebug (for Firefox) and noticed that the real problem lied with the amount of data being returned in update panel responses. Within the UpdatePanel control there is a table that contains a number of ListBox controls. The real problem is that EVERY OTHER TIME the response (from making ListBox selections) alternates from 30K to 430K. Firefox handles the 400+K response in a reasonable amount of time. For whatever reason, IE7 goes CPU bound while it is presumably processing this data. So irrespective of whether or not we should be using an UpdatePanel or not, we'd like to figure out why every other async postback response is larger by a factor of more than 10 than the previous one. When the response is in the 30K range, IE updates the display within a second. On the alternate times, the response time is well over 10 times longer. Any idea why this alternating behavior should be happening with an UpdatePanel?

  • Schema objects not visible in SQL Server Management Studio 2008

    - by Germ
    I'm experiencing a weird problem with a SQL login. When I connect to the server in Microsoft SQL Server Management Studio (2008) using this account, I cannot see any of the tables, stored procedures etc. that this account should have access to on a particular database. When I connect to the same server within Visual Studio (2008) with the same account everything is there. When I connect with the same account on a Virtual Machine everything is there. I've also had a co-worker connect to the server using the same login and he's able to view everything as well. I use Microsoft SQL Server Management Studio all day connecting to different servers and databases and I've never experienced this problem. Does anyone have any suggestions on how I can diagnose this problem? I've checked to make sure I don't have any Table filters etc. There's several database on this server and I'm able to see the correct tables that this account has access to in the other databases just fine. Running this query lists the tables I'm expecting to see. SELECT * FROM INFORMATION_SCHEMA.TABLES

  • Click in a ListView item changes status of elements inside the item?

    - by Antonio
    Hi, I don't know exactly how to explain this problem, but I'll try. I have a ListView with several items. Each item has inside a TextView and two ImageView. I want the ImageView change when I click on them, and I want to open a context menu when I press for a long time into the ListView item. For the ImageView, everything works properly. For the whole item, I can show the context menu after a long press, but my problem is that the ImageView changes as well when I am pressing the TextView, for example. Somo pieces of my code: ListView item: <TextView android:id="@+id/title" android:textColor="@color/black" android:maxLines="2" android:textSize="14dip" /> <ImageView android:id="@+id/minus" android:src="@drawable/minusbutton" android:adjustViewBounds="true" android:gravity="center" /> <ImageView android:id="@+id/plus" android:src="@drawable/plusbutton" android:adjustViewBounds="true" android:gravity="center" /> Drawable to change the status of the plus button: <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_enabled="false" android:drawable="@drawable/button_add_normal_disabled" /> <item android:state_enabled="true" android:state_pressed="true" android:drawable="@drawable/button_add_pressed" /> <item android:state_enabled="true" android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/button_add_active" /> <item android:state_enabled="true" android:state_focused="false" android:state_pressed="false" android:drawable="@drawable/button_add_normal" /> I hope you understand my problem. I think that all the children of a view are affected by an event in the parent, but I am not sure. Do you have a solution? Thanks in advance

  • Dynamics CRM Customer Portal Accelerator Installation

    - by saturdayplace
    (I've posted this question on the codeplex forums too, but have yet to get a response) I've got an on-premise installation of CRM and I'm trying to hook the portal to it. My connection string in web.config: <connectionStrings> <add name="Xrm" connectionString="Authentication Type=AD; Server=http://myserver:myport/MyOrgName; User ID=mydomain\crmwebuser; Password=thepassword" /> </connectionStrings> And my membership provider: <membership defaultProvider="CustomCRMProvider"> <providers> <add connectionStringName="Xrm" applicationName="/" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Hashed" minRequiredPasswordLength="1" minRequiredNonalphanumericCharacters="0" name="CustomCRMProvider" type="System.Web.Security.SqlMembershipProvider" /> </providers> </membership> Now, I'm super new to MS style web development, so please help me if I'm missing something. In Visual Studio 2010, when I go to Project ASP.NET Configuration it launches the Web Site Administration Tool. When I click the Security Tab there, I get the following error: There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: An error occurred while attempting to initialize a System.Data.SqlClient.SqlConnection object. The value that was provided for the connection string may be wrong, or it may contain an invalid syntax. Parameter name: connectionString I can't see what I'm doing wrong here. Does the user mydomain\crmwebuser need certain permissions in the SQL database, or somewhere else? edit: On the home page of the Web Site Administration Tool, I have the following: **Application**:/ **Current User Name**:MACHINENAME\USERACCOUNT Which is obviously a different set of credentials than mydomain\crmwebuser. Is this part of the problem?

  • jquery ajax call from link loaded with ajax

    //deep linking $("document").ready(function(){ contM = $('#main-content'); contS = $('#second-content'); $(contM).hide(); $(contM).addClass('hidden'); $(contS).hide(); $(contS).addClass('hidden'); function loadURL(URL) { //console.log("loadURL: " + URL); $.ajax({ url: URL, type: "POST", dataType: 'html', data: {post_loader: 1}, success: function(data){ $(contM).html(data); $(contM).animW(); } }); } // Event handlers $.address.init(function(event) { //console.log("init: " + $('[rel=address:' + event.value + ']').attr('href')); }).change(function(event) { $.ajax({ url: $('[rel=address:' + event.value + ']').attr('href'), type: "POST", dataType: 'html', data: {post_loader: 1}, success: function(data){ $(contM).html(data); $(contM).animW(); }}); //console.log("change"); }) $('.update-main a').live('click', function(){ loadURL($(this).attr('href')); }); $(".update-second a").live('click', function() { var link = $(this); $.ajax({ url: link.attr("href"), dataType: 'html', data: {post_loader: 1}, success: function(data){ $(contS).html(data); $(contS).animW(); }}); }); }); I'm using jquery and the 'addresses' plugin to load content with ajax and maintain pagination. The problem I'm having is some content loads with links which are intended to load content into a secondary window. I'm using the .live() method to allow jquery to listen for new links loaded into the primary content div. This works until the .ajax() method is called for these fresh links loaded with ajax, where the method begins, but follows the original link before data can be received. I'm assuming the problem is in the client-side scripting, but it may be a problem with the call made to the server. I'm using the wordpress loop to parse the url and generate the html loaded via jquery. Thanks for any tips!

  • WPF Memory Leak on XP (CMilChannel, HWND)

    - by vanja.
    My WPF application leaks memory at about 4kb/s. The memory usage in Task Manager climbs constantly until the application crashes with an "Out of Memory" exception. By doing my own research I have found that the problem is discussed here: http://stackoverflow.com/questions/801589/track-down-memory-leak-in-wpf and #8 here: http://blogs.msdn.com/jgoldb/archive/2008/02/04/finding-memory-leaks-in-wpf-based-applications.aspx The problem described is: This is a leak in WPF present in versions of the framework up to and including .NET 3.5 SP1. This occurs because of the way WPF selects which HWND to use to send messages from the render thread to the UI thread. This sample destroys the first HWND created and starts an animation in a new Window. This causes messages sent from the render thread to pile up without being processed, effectively leaking memory. The solution offered is: The workaround is to create a new HwndSource first thing in your App class constructor. This MUST be created before any other HWND is created by WPF. Simply by creating this HwndSource, WPF will use this to send messages from the render thread to the UI thread. This assures all messages will be processed, and that none will leak. But I don't understand the solution! I have a subclass of Application that I am using and I have tried creating a window in that constructor but that has not solved the problem. Following the instructions given literally, it looks like I just need to add this to my Application constructor: new HwndSource(new HwndSourceParameters("MyApplication"));

  • How to dispose a Writeable Bitmap? (WPF)

    - by Mario
    Some time ago i posted a question related to a WriteableBitmap memory leak, and though I received wonderful tips related to the problem, I still think there is a serious bug / (mistake made by me) / (Confusion) / (some other thing) here. So, here is my problem again: Suppose we have a WPF application with an Image and a button. The image's source is a really big bitmap (3600 * 4800 px), when it's shown at runtime the applicaton consumes ~90 MB. Now suppose i wish to instantiate a WriteableBitmap from the source of the image (the really big Image), when this happens the applications consumes ~220 MB. Now comes the tricky part, when the modifications to the image (through the WriteableBitmap) end, and all the references to the WriteableBitmap (at least those that I'm aware of) are destroyed (at the end of a method or by setting them to null) the memory used by the writeableBitmap should be freed and the application consumption should return to ~90 MB. The problem is that sometimes it returns, sometimes it does not. Here is a sample code: // The Image's source whas set previous to this event private void buttonTest_Click(object sender, RoutedEventArgs e) { if (image.Source != null) { WriteableBitmap bitmap = new WriteableBitmap((BitmapSource)image.Source); bitmap.Lock(); bitmap.Unlock(); //image.Source = null; bitmap = null; } } As you can see the reference is local and the memory should be released at the end of the method (Or when the Garbage collector decides to do so). However, the app could consume ~224 MB until the end of the universe. Any help would be great.

  • Fastest way to remove non-numeric characters from a VARCHAR in SQL Server

    - by Dan Herbert
    I'm writing an import utility that is using phone numbers as a unique key within the import. I need to check that the phone number does not already exist in my DB. The problem is that phone numbers in the DB could have things like dashes and parenthesis and possibly other things. I wrote a function to remove these things, the problem is that it is slow and with thousands of records in my DB and thousands of records to import at once, this process can be unacceptably slow. I've already made the phone number column an index. I tried using the script from this post: http://stackoverflow.com/questions/52315/t-sql-trim-nbsp-and-other-non-alphanumeric-characters But that didn't speed it up any. Is there a faster way to remove non-numeric characters? Something that can perform well when 10,000 to 100,000 records have to be compared. Whatever is done needs to perform fast. Update Given what people responded with, I think I'm going to have to clean the fields before I run the import utility. To answer the question of what I'm writing the import utility in, it is a C# app. I'm comparing BIGINT to BIGINT now, with no need to alter DB data and I'm still taking a performance hit with a very small set of data (about 2000 records). Could comparing BIGINT to BIGINT be slowing things down? I've optimized the code side of my app as much as I can (removed regexes, removed unneccessary DB calls). Although I can't isolate SQL as the source of the problem anymore, I still feel like it is.

  • How to prove writing specifications beats code cowboys?

    - by Andrew Grant
    So I have a problem. Or rather my friend has a problem, since I would never write about my company on an internet forum. At my friend's company specification writing is, shall we say, a little underused. There's a deeply ingrained culture of writing code first and asking questions later, whether it's for a library routine or a new tool to inflict on their long suffering designers. This of course leads to situations where functionality is partially correct, incorrect, or just completely missing ("oh, just save before trying anything you may want to undo"). This usually results in a loss of productivity for those poor designers, or beta periods where bug-fixing is largely spent implementing things correctly. My friend's found his suggestions of writing (and testing against) specifications to be generally well received. Most of his colleagues have embraced the wonderful feeling of discovering false-assumptions on paper, instead of at 11pm on a Sunday in the middle of beta. Viva La Revolution! However there are a few who poo-poo anything that stands between their task and a keyboard. They laugh at the thought of actually designing anything, and write code with merry abandon. Mostly these are senior, long employed developers, reluctant to "waste time". The problem is that this second group of heretics invariably produce things (or at least something) quicker than the first. Subsequently this becomes justification along the lines of "It's pointless to write specifications for something as simple as an image resizer! Oh and those bugs where width!=height or the image uses RLE just need a few tweaks". And now the question :) Other than saying "told you so" at the end of a project, what are some good short-term ways to demonstrate how the practice of writing functional or technical specifications leads to better software in the long run? Cheers!

  • IE innerHTML chops sentence if the last word contains '&' (ampersand)

    - by Mandai
    I am trying to populate a DOM element with ID 'myElement'. The content which I'm populating is a mix of text and HTML elements. Assume following is the content I wish to populate in my DOM element. var x = "<b>Success</b> is a matter of hard work &luck"; I tried using innerHTML as follows, document.getElementById("myElement").innerHTML=x; This resulted in chopping off of the last word in my sentence. Apparently, the problem is due to the '&' character present in the last word. I played around with the '&' and innerHTML and following are my observations. If the last word of the content is less than 10 characters and if it has a '&' character present in it, innerHTML chops off the sentence at '&'. This problem does not happen in firefox. If I use innerText the last word is in tact but then all the HTML tags which are part of the content becomes plain text. I tried populating through jQuery's #html method, $("#myElement").html(x); This approach solves the problem in IE but not in chrome. How can I insert a HTML content with a last word containing '&' without it being chopped off in all browsers?

  • Memory leak when using Workflow 4.0 SqlWorkflowInstanceStore and PersistableIdleAction.Unload

    - by Rohland
    Hi, This particular problem is driving me nuts. I wonder if anyone has experienced a similar problem. If I load up a workflow then unload it and perform a memory snapshot then the result is predictable - my workflow is no longer in memory. However, if I load up a workflow and set the PersistableIdle action to PersistableIdleAction.Unload and let the workflow idle the workflow remains in memory even though the Unload action fires. I used ANTS Memory Profiler to debug this issue. This is the object retention graph outputted showing that an internal object is hanging onto my workflow instance. Can anyone else verify this problem? My code amounts to the following: Create SqlWorkflowInstanceStore and setup lock owner handle -- At this point I take a memory snapshot Create an instance of Workflow1 Set the PersistableIdle action Apply the instancestore to Workflow1 Setup action event handlers for Idle, Unload, UnhandledException etc. Persist the workflow instance Run the workflow instance Wait for instance to idle (caused by Delay activity) Ensure the Unload action is fired -- At this point I take a second memory snapshot From the above image, it is clear that the only object referencing Workflow1 is some internal event handlers result which I have no ability to dispose of. Any clues?

  • PHP Mystery Theatre - HTML Element doesn't display when served with php5, restart server with php4 a

    - by togglemedia
    Get this...I start the server in php5 and a specific HTML element ('a' element with a background image) is nowhere to be seen, I reboot the server in php4 and the HTML element is displaying properly. I boot back and forth between php5 and php4 with absolute consistent results, not displaying in php5 and displaying in php4. The thing that blows my mind is that: the HTML is consistent between boots of php5/4, so both scenarios have the necessary HTML elements the CSS is consistent between boots of php5/4, so both scenarios have the necessary CSS definitions there is an identically styled sibling element, with different class name that displays properly the problem is reproducible between browsers, between platforms. I've tested it on every possible config, Mac/Windows, IE6,7,8, FireFox, Safari etc... When the server is booted in php5 there is one HTML element that just doesn't display/render. A stab in the dark, I turned on PHP error reporting in php5 (to see if there would be any clues there) and low and behold the HTML element is now rendering in php5. I turn off PHP error reporting, and restart php5 and the HTML element is still rendering in php5, and the problem has been fixed...and I can't get the problem to reproduce. This is why my curiosity has brought me here. I just spent about four hours scratching my head trying to figure out how this could be. And now, I ask any php web dev gurus out there...what the heck was this all about?

  • Eclipse Plugin does not work in FlashBuilder/FlexBuilder Standalone

    - by Janosch
    Hi, created an Eclipse plugin that contributes to the UI by a new project wizard a new menu in the context menu of projects in the Package Explorer a new project nature + builder a new preference page for the plugin The plugin works fine when installed in a normal Eclipse instance with Flex/Flashbuilder as plugin. The problem now is, that the plugin never gets activated when i install it in a Flex/Flashbuilder Standalone instance. Neither of the features described above is available. I even have no idea how to debug this, error-log (workspace/.metadata/.log) the following message appears, (but i dont think it is related to the problem) !ENTRY org.eclipse.ui.workbench 2 0 2009-07-20 17:51:17.984 !MESSAGE A handler conflict occurred. This may disable some commands. !SUBENTRY 1 org.eclipse.ui.workbench 2 0 2009-07-20 17:51:17.984 !MESSAGE Conflict for 'org.eclipse.ui.navigate.openResource': HandlerActivation(commandId=org.eclipse.ui.navigate.openResource, handler=ActionDelegateHandlerProxy(null,org.eclipse.ui.internal.ide.handlers.OpenResourceHandler), expression=AndExpression(ActionSetExpression(org.eclipse.ui.NavigateActionSet,org.eclipse.ui.internal.WorkbenchWindow@1c45731),WorkbenchWindowExpression(org.eclipse.ui.internal.WorkbenchWindow@1c45731)),sourcePriority=16640) HandlerActivation(commandId=org.eclipse.ui.navigate.openResource, handler=ActionDelegateHandlerProxy(null,org.eclipse.ui.internal.ide.handlers.OpenResourceHandler), expression=AndExpression(ActionSetExpression(com.adobe.flexbuilder.standalone.navigate,org.eclipse.ui.internal.WorkbenchWindow@1c45731),WorkbenchWindowExpression(org.eclipse.ui.internal.WorkbenchWindow@1c45731)),sourcePriority=16640) In the "Configuration Details" my feature doesn't show up in the *** Features: section and my plugin doesn't show up in the *** Plugin-in Registry: section. But they appear under Configured features and Configured plug-ins. Starting FlashBuilder with -clean didn't solve the problem. (the start command is now "C:\Programme\Adobe\Flash Builder Beta\Gumbo.exe" -clean) My plugin depends on org.eclipse.ui, org.eclipse.core.runtime, org.eclipse.core.resources, com.adobe.flexbuilder.project com.adobe.flexbuilder.project.ui com.adobe.flexbuilder.ui All of these should be available, as i see it. (and an error should be generated if they were not, i hope)
