• "Initializing - Busy - Stopping" LOOP issue in Azure deployement

  - by Kushal Waikar

  Hi folks, I am trying to deploy an azure cloud application on Windows Azure. Application specifications are -- It has one WebRole - ASP.Net MVC Application (ASP.Net charting control is used in this MVC application) It does not contain any worker role. Third party references are set with property "copy Local" to "true"(MVC,ASP Charting control & ASP Provider DLLs) There is no DiagnosticsConnectionString in service configuration file It uses ASP provider for session state management. This application runs successfully on local dev fabric but when I try to deploy it on Windows Azure it gets stuck in a loop with status being changed between Initializing, Busy, Stopping states. It never goes into READY state. It seems that there are no ERROR logs for conveying the deployment issues to user. So is there any way to diagnose deployment issues ? Is there any way to get deployment ERROR logs ? Any kind of help will be appreciated. Thanks, Kushal

• Problems getting foreign keys working in MySQL

  - by thehuby

  I've been trying to get a delete to cascade and it just doesn't seem to work. I'm sure I am missing something obvious, can anyone help me find it? I would expect a delete on the 'articles' table to trigger a delete on the corresponding rows in the 'article_section_lt' table. CREATE TABLE articles ( id INTEGER UNSIGNED PRIMARY KEY AUTO_INCREMENT, url_stub VARCHAR(255) NOT NULL UNIQUE, h1 VARCHAR(60) NOT NULL UNIQUE, title VARCHAR(60) NOT NULL, description VARCHAR(150) NOT NULL, summary VARCHAR(150) NOT NULL DEFAULT "", html_content TEXT, date DATE NOT NULL, updated TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP )ENGINE=INNODB; CREATE TABLE article_sections ( /* blog, news etc */ id INTEGER UNSIGNED PRIMARY KEY AUTO_INCREMENT, url_stub VARCHAR(255) NOT NULL UNIQUE, h1 VARCHAR(60) NOT NULL, title VARCHAR(60) NOT NULL, description VARCHAR(150) NOT NULL, summary VARCHAR(150) NOT NULL DEFAULT "", html_content TEXT NOT NULL DEFAULT "" )ENGINE=INNODB; CREATE TABLE article_section_lt ( fk_article_id INTEGER UNSIGNED NOT NULL REFERENCES articles(id) ON DELETE CASCADE, fk_article_section_id INTEGER UNSIGNED NOT NULL )ENGINE=INNODB;

• Is there a tool to navigate targets and properties 's definition?

  - by Nam Gi VU

  I'm working on a bundle of MSBuild script files and many many times I have the need of locating the definition of a called target or a property being used. At the moment, I have to search to the target/property 's name text and view the file containing that text - only then I can read the definition of the target/property I'm looking for. This remind me of the feature of class/variable navigation of Visual Studio: we can choose "Go to definition" or "Find references" when select a class name or a variable. Is there a similar way to work with MSBuild target/property/item? Hope to hear from all of you! Nam.

• What's the reason both Image and Bitmap classes don't implement a custom equality/hashcode logic?

  - by devoured elysium

  From MSDN documentation, it seems as both GetHashCode() and Equals() haven't been overriden in Bitmap. Neither have them been overriden in Image. So both classes are using the Object's version of them just compares references. I wasn't too convinced so I decided to fire up Reflector to check it out. It seems MSDN is correct in that matter. So, is there any special reason why MS guys wouldn't implement "comparison logic", at least for the Bitmap class? I find it is kinda acceptable for Image, as it is an abstract class, but not so much for the Bitmap class. I can see in a lot of situations calculating the hash code can be an expensive operation, but it'd be alright if it used some kind of lazy evaluation (storing the computed hash code integer in a variable a variable, so it wouldn't have to calculate it later again). When wanting to compare 2 bitmaps, will I have to resort to having to run all over the picture comparing each one of its pixels? Thanks

• jQuery droppable accordion

  - by awshepard

  I've been playing around with trying to create a droppable accordion for a little while, and haven't gotten it to be very responsive. When I drag an item over the accordion, it takes 5+ seconds for the accordion element to open (if it does at all). Sometimes I have to "wave" the dragged element over the accordion element. I know I read something a while back about event processing in javascript - something along the lines of the browser not always passing control to the javascript engine when you think it does, or something like that, resulting in weird timing. Has anyone else seen tried to do this before? Have you found jquery/javascript to be this slow? Do you have any references for how to get a responsive droppable accordion (the jQuery UI site doesn't seem to, and I didn't find anything on SO or Google). Thanks!

• How does a programmer think?

  - by Gordon Potter

  This may be a hopelessly vague question. But I am interested to hear whatever logical thought processes people go through when learning a new concept or trying to get their brain around code they might not have ever seen before. Basically, what general steps does one take to to break down problems and what does it take to "get it"? If you were to diagram a flowchart of how your mental process works when you look at code or try to solve a problem what might it look like? What common references, tips, and mental assumptions do you find useful in problem solving? How is this different between different domains? For example in what ways is a web programmer's thought process similar or different from a traditional desktop app developer's process?

• Cannot find maven dependency, mysterious jar files

  - by natasha

  Hi, I am trying to build a simple war file which has a few jsps. However I am coming across an odd issue, for some reason during the packaging maven is pulling 4 jar files into the WEB-INF/lib. I have trimmed down all the fat from the pom file, and have grepped for any references to these jars without any success. I cannot figure out where maven is pulling them from. I tried 'mvn dependency:build-classpath' and the classpath is empty. Please help, these jars are corrupt and I cannot deploy this war file because of them. Thanks, natasha

• Silverlight 4 Assembly Sharing Problem

  - by jeffn825

  I have a WPF .NET 4.0 class library referencing a Silverlight 4 class library. The SL library compiles fine but when I compile the WPF class library, I get: Error 2 Unknown build error, 'Cannot resolve dependency to assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.' MyProj.Presentation.Wpf I figure the problem must be similar to the one mentioned here: http://markti.spaces.live.com/blog/cns!D92CF278F0F91957!273.entry but my WPF library doesn't contain any XAML that references a user control from my SL library. In fact, my SL library doesn't have any XAML in it at all. It does, however, have several shared DependencyObjects, such as an EventCommander (binding UI element events to Commands), and some DataTemplate helpers. Is there any way I can narrow down the problem here? And has anyone found a way of effectively referencing UI elements in a SL4 project from .NET 4.0? Thanks.

• Looking for an elegant way to store one-to-many relationship in coredata when order is important

  - by Eric Schweichler

  I've been trying to come up with a way to solve my problem, but every solution I can think of is messy and makes me want to retch. I have a one-to-many relationship, consisting of a Team object that can have many Member objects. When I built my data model using Xcode, I was given the default NSSet in which to store the member objects, Unfortunately Sets are not ordered and I need to preserve the order of the Member objects and I need to know if there are empty spaces between Members. I thought of Using an NSArray in place of the NSSet and creating a dummy Member object in my data store that I could use to mark vacant a spot between to Member objects, but that solution really feels like too much of a hack to me. Since I'll always have to filter out this dummy Member from any queries. An NSDictionary would be perfect as I could store the Member object references and their positions as Object-Key pairs, (taking care of both order and vacancies) but apparently CoreData does not support NSDictionary. Has anyone had a similar need, and devised a simple solution?

• Using Large Lists

  - by cam

  In an Outlook AddIn I'm working on, I use a list to grab all the messages in the current folder, then process them, then save them. First, I create a list of all messages, then I create another list from the list of messages, then finally I create a third list of messages that need to be moved. Essentially, they are all copies of eachother, and I made it this way to organize it. Would it increase performance if I used only one list? I thought lists were just references to the actual item.

• ToolStripComboBox + objects default string value

  - by Martin

  I am using a ToolStripComboBox to list some data. I am populating this combo with some custom objects: For Each obj As myObject In myObjectList myToolStripComboBox.Items.Add(obj) Next This works great except the text displayed in the combo is the name of the object class. I can understand why and realise that I need to do something to make the combo use a property from my class instead. The help files state: To add objects to the list at run time, assign an array of object references with the AddRange method. The list then displays the default string value for each object. You can add individual objects with the Add method. The bit in bold suggests I need to setup the default string value in my class. How would I go about doing this?

• Unresolved symbol when inheriting interface

  - by LeopardSkinPillBoxHat

  It's late at night here and I'm going crazy trying to solve a linker error. If I have the following abstract interface: class IArpPacketBuilder { public: IArpPacketBuilder(const DslPortId& aPortId); virtual ~IArpPacketBuilder(); // Other abstract (pure virtual methods) here... }; and I instantiate it like this: class DummyArpPacketBuilder : public IArpPacketBuilder { public: DummyArpPacketBuilder(const DslPortId& aPortId) : IArpPacketBuilder(aPortId) {} ~DummyArpPacketBuilder() {} }; why am I getting the following error when linking? Unresolved symbol references: IArpPacketBuilder::IArpPacketBuilder(DslPortId const&): ppc603_vxworks/_arpPacketQueue.o IArpPacketBuilder::~IArpPacketBuilder(): ppc603_vxworks/_arpPacketQueue.o typeinfo for IArpPacketBuilder: ppc603_vxworks/_arpPacketQueue.o *** Error code 1 IArpPacketBuilder is an abstract interface, so as long as I define the constructors and destructions in the concrete (derived) interface, I should be fine, no? Well it appears not.

• htaccess - rewrite rule issue - not able to get 10th variable

• Can I to remove the labels from the bibliography and keeping it in the reference?

  - by Tae

  I'm writing the bibliography of my report with thebibliography environment because I don't need a BibTeX database (or I don't have the time for learn how to customize or write a style). Well, using the optional argument [label] I can specify as I want the cite references are show, for example: \bibitem[PNUD1996]{PNUD1996} PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. So, if I write: in \cite{PNUD1996}. it produces: in [PNUD1996]. But the label also appear in the bibliography: [PNUD1996] PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996. Can I to remove the label from the bibliography and keeping it in the reference? I mean, to get: in [PNUD1996]. and PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996.

• What ways can I put images in a grid-like format?

  - by Peter

  I have about 12-15 images that I want to align together in a grid, with text under each image. I thought about using a table, but I hear that tables aren't the best way to go these days. I tried a few other things, but nothing seemed to work the way I wanted it to. An example of what I want it to look like would be something like this: [-----Image-----] [-----Image-----] [-----Image-----] [-----Image-----] --- Row 1 (--Description-) (-Description-) (-Description-) (-Description-) [-----Image-----] [-----Image-----] [-----Image-----] [-----Image-----] --- Row 2 (--Description-) (-Description-) (-Description-) (-Description-) and so on... What are some other methods, besides tables, that I should look into using? Any suggestions or references would be helpful.

• Error: A SQLParamenter wtih ParameterName @myparm is not contained by this SQLParameter Collection

  Good Morning, I'm working on an ASP.NET 3.5 webforms application and have written the following code: Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Dim connectionString As String = WebConfigurationManager.ConnectionStrings("Diel_inventoryConnectionString").ConnectionString Dim con As New SqlConnection(connectionString) Dim adapter1 As New SqlDataAdapter adapter1.SelectCommand = New SqlCommand adapter1.SelectCommand.CommandType = CommandType.StoredProcedure adapter1.SelectCommand.CommandText = "PartSproc" Dim parmNSN As New SqlParameter("@NSN", SqlDbType.NVarChar) Dim parmName As New SqlParameter("@PartName", SqlDbType.NVarChar) txtNSN.Text = adapter1.SelectCommand.Parameters("@NSN").Value txtSearch.Text = adapter1.SelectCommand.Parameters("@PartName").Value Dim dt As New DataTable() adapter1.Fill(dt) MySearch.DataSource = dt MySearch.DataBind() End Sub When I run the page, I receive the error A SQLParameter with @NSN is not contained by this SQLParameter Collection. I tried using apostrophes around the @NSN and @PartName but that does not work either and presents expression expected error. How might I rectify the above code so that it references the @NSN and @PartName parameters correctly? Thanks, Sid

• NTFS-compressing Virtual PC disks (on host and/or guest)

  - by nlawalker

  I'm hoping someone here can answer these definitively: Does putting a VHD file in an NTFS-compressed folder on the host improve performance of the virtual machine, diminish performance, or neither? What about using NTFS compression within the guest? Does using compresssion on either the host or the guest lead to any problems like read or write errors? If I were to put a VHD in a compressed folder on the host, would I benefit from compacting it? I've seen references to using NTFS compression on quite a few VPC "tips and tricks" blog posts, and it seems like half of them say to never do it and the other half say that not only does it save disk space but it actually can improve performance if you have a fast CPU and your primary performance bottleneck is the disk.

• Xap file contents changes if built in Visual Studio or build server

  - by arch

  I'm using MEF with my Silverlight 4 app to dynamically load xap files. To optimize this process, I've removed various assemblies from my xaps since I know they've already been loaded by the base xap. This reduces the size of my dynamically loaded xaps. I accomplished this by setting the "Copy Local" flag for each assembly reference to "false". This all seems to work fine when I build in Visual Studio 2010 - my xaps are much smaller. However, when the same projects are built by the build server, all the excluded references are once again in the xap file hence tripling the size of the xap. I've read several blogs/articles regarding similar experiences but no resolution. Very frustrating - any help is appreciated.

• Expected specifier-qualifier-list before ... only in classes in a certain folder

  - by funkybro

  Hi Classes in my iPhone project are organised within folders on the filesystem, these correspond to groups (for each folder) in xcode. My problem is that there seems to be a particular class which classes in a particular group/folder cannot make reference to; the compiler complains of "Expected specifier-qualifier-list...". This happens on any class within this group, and also when I create a new class within this group and try and import the offending class like so: #import <Foundation/Foundation.h> #import "MyClass.h" @interface TryingToImport : NSObject { MyClass *myClass; // Expected specifier-qualifier-list before 'MyClass' } Creating an identical class in any other group works OK. I understand this error message is usually due to cyclical import references, I have checked over and over and there don't seem to be any of these. I assume I have inadvertantly configured the offending group to be different to the others in some way but I can't figure out how. Help please!

• Can you automatically create a mysqldump file that doesn't enforce foreign key constraints?

  - by Tai Squared

  When I run a mysqldump command on my database and then try to import it, it fails as it attempts to create the tables alphabetically, even though they may have a foreign key that references a table later in the file. There doesn't appear to be anything in the documentation and I've found answers like this that say to update the file after it's created to include: set FOREIGN_KEY_CHECKS = 0; ...original mysqldump file contents... set FOREIGN_KEY_CHECKS = 1; Is there no way to automatically set those lines or export the tables in the necessary order (without having to manually specify all table names as that can be tedious and error prone)? I could wrap those lines in a script, but was wondering if there is an easy way to ensure I can dump a file and then import it without manually updating it.

• Separation of interfaces and implementation

  - by bonefisher

  From assembly(or module) perspective, what do you think of separation of Interface (1.assembly) and its Implementation (2.assembly)? In this way we can use some IoC container to develop more decoupling desing.. Say we have an assembly 'A', which contains interfaces only. Then we have an assembly 'B' which references 'A' and implements those interfaces..It is dependent only on 'A'. In assembly 'C' then we can use the IoC container to create objects of 'A' using dependency injection of objects from 'B'. This way 'B' and 'C' are completely unaware (not dependent) of themselves..
