  • [ext js] Renderer for ColumnTree?

    - by Chris Cowdery-Corvan
    Hello! I'm trying to add a custom renderer to a ColumnTree in Ext JS. Since it appears(?) that this isn't supported, does anyone know of any workaround to use a renderer? Here's a snippet of code - let's just say (hypothetically) that I have a renderer I'd like to use for the documentsVersion tab below - does anyone have any ideas? return new Ext.tree.ColumnTree({ autoHeight: false, rootVisible: showRoot, autoScroll: false, id: (!treeId)? window.mainTreeId: treeId, loader: (!loader)?window.docTreeLoader:loader, columns: [{ header:"${documentsTitle}", width: windowWidth * 0.40 }, { header:"${documentsVersion}", width: windowWidth * 0.10, dataIndex:'version' }, Thanks!

  • PHP with DB backed-end application to complete windows EXE possible or not?

    - by Devyn
    Hi, Let's say I have a php application backed-end with SQLite and I would like to convert whole application to exe file so the end user can just click it and run on windows. User should be able to save, update and add new data into database without any web server or browser things. Is it possible? I found out that we can use PHP-GTK for UI. exeoutput.com supports with database engines according to it's website. Anyone have tried it out? If I'm missing something, pls share with me. Thanks all in advance and happy new year!!!

  • a missing variable in a switch statement ?!!

    - by mechhfly
    hi folks, i have a strange issue. a variable seems to be missing during a pass through a case statement i have a function like so function checklink($var0, $var1, $var2) { switch($var0) { case "case1": print $var2; //code uses $var2 successfully case "case2": print $var2; //variable has disappeared! } } essentially what i am doing is constructing a string from the last variable based on the first. if i run the code in which the first case is true, i get the expected results, but when i run the second case, my variable seems to have vanished. these first two case statements are syntactically the same and the variable is gathered from the $_GET array (hard coded into hyperlink). any light on this issue? if more explanation is needed let me know, its late and my brain is getting mushy. thanks my friends.

  • Using DockPanel Suite's XML saving with My.Settings

    - by Cyclone
    In vb.net, how can I use SaveAsXML and LoadFromXML (DockPanel Suite functions) with My.Settings? I know there is a way to save it to a stream, but I don't know enough about System.IO to do this. DockPanel Suite: http://sourceforge.net/projects/dockpanelsuite/ I would very much prefer to store configuration using My.Settings instead of as an XML file. Thanks for the help! EDIT: Since the only person to answer so far has since deleted their answer, I feel I should explain further: Those two methods can both accept a stream object, but I have not used System.IO enough to know how to properly initialize a stream, let alone get a string out of a stream. EDIT: Googling has gotten me nowhere. EDIT: Still waiting for this. I've tried everything...

  • What type of git server do you use? or how do you use git?

    - by Johan
    Hi Let's say we have a small team, 1-5 persons. What type of "git setup" would you use? Would you use gitweb and apache so you could run over http? Or would you use the user-accounts and ssh in some way? Today I'm familiar to use SubVersion thou apache (http), but I'm not sure it is right to setup to use git the same way... Thanks Johan Update: It feels like if we combine the answer that Dietrich Epp and the one hallidave gave I could get a quick and good solution. A common dir in the servers filesystem where all can write, and that dir is also exposed with apache. That way everybody can always get the latest, but only trusted people can write to it...

  • Hash of unique value = unique hash?

    - by Nebs
    Theoretically does hashing a unique value yield a unique value? Let's say I have a DB table with 2 columns: id and code. id is an auto-incrementing int and code is a varchar. If I do ... $code = sha1($id); ... and then store $code into the same row as $id. Will my code column be unique as well? What about if I append the current time? eg: $code = sha1($id . time()); Thanks.

  • MS Dynamics CRM 4.0 - onChange event error

    - by Brett
    Hi I have an onChange event that keeps bringing up the error below whenever I preview it. 'Object doesnt support this property or method' I have the onChange event associated with a picklist and when a specific option is selected another field is unhidden. The code is below: onLoad: //If How did you hear about us is set to event show the Source Event lookup crmForm.SourceEvent = function SourceEvent() { if (crmForm.all.gcs_howdidyouhearaboutus.DataValue == 5) { crmForm.all.gcs_sourceeventid_c.style.display = '' ; crmForm.all.gcs_sourceeventid_d.style.display = '' ; } else { crmForm.all.gcs_sourceeventid_c.style.display = 'none' ; crmForm.all.gcs_sourceeventid_d.style.display = 'none' ; } } crmForm.SourceEvent() ; onChange crmForm.SourceEvent() ; Would be great if someone could let me know why this error is showing up? Also, this has happened on a few onChange events on the form preview but once published onto the live system it does not error. Any ideas? Thank you Brett

  • Html Attribute for Html.Dropdown

    - by kapil
    I am using a dropdown list as follows. <%=Html.DropDownList("ddl", ViewData["Available"] as SelectList, new { CssClass = "input-config", onchange = "this.form.submit();" })%> On its selection change I am invoking post action. After the post the same page is shown on which this drop down is present. I want to know about the HTML attribute for the drop down which will let me preserve the list selection change. But as of now the list shows its first element after the post. e.g. The dropdoen contains elements like 1,2,3,etc. By default 1 is selected. If I select 2, the post is invoked and the same page is shown again but my selection 2 goes and 1 is selected again. How can preserve the selection? Thanks, Kapil

  • Determining URLs updated via a series of commit logs

    - by adamrubin
    I'm working on a project where I programmatically need to know when a URL has been changed by a developer, post or during deploy. The obvious answer may be to curl the URL one day, save the output, then curl and in x days then do a diff. That won't work in my case, as I'm only looking for changes the developer mande. If the site is a blog, new comments, user submitted photos, etc would make that curl diff useless. RoR example, using github. Let's assume I have access to the entire repository and all commit logs between iterations. Is there a way I could see that "/views/people/show.html.erb" was commited, then backtrack from there (maybe by inspecting routes.rb), to come up with the URL I can then hit via a browser?

  • Apache on linux : spawning processes or threads ?

    - by Jerome WAGNER
    Hello, I would like to understand better exactly what is going on when Apache on linux receive an HTTP request in a process pre-fork model. Let's say we have 20 Apache child processes waiting. When I receive an HTTP request, is it true to say that 1 child process will be chosen to handle the request and that this process won't handle another request from another user until the first one is finished ? I am asking the question because of a PHP limitation that states : The locale information is maintained per process, not per thread. If you are running PHP on a multithreaded server API like IIS or Apache on Windows, you may experience sudden changes in locale settings while a script is running, though the script itself never called setlocale(). This happens due to other scripts running in different threads of the same process at the same time, changing the process-wide locale using setlocale(). Thanks Jerome Wagner

  • Object/Module not found: RDS from VB6 app to a Win2003 server

    - by Cyberherbalist
    I have a rather legacy application EXE written in VB6 and running on a Windows 2000 server that uses RDS (Remote Data Services) to access a business object DLL (also written in VB6) running on a Windows 2003 server. The DLL has never run on this server (we're moving the component off the old W2K server), but it is registered and defined as a component on the W2k+3 server. The specific code where the DLL is being called is: Private m_rdsDS As RDS.DataSpace Dim oARImport As Object Set oARImport = m_rdsDS.CreateObject("ARBatches.BL_ARBatches", txtWebServer) MsgBox oARImport.AddBatches(m_vConnParms, arbParseString, LinesFromFile) The CreateObject appears to work fine, but calling the method AddBatches raises the error number 8209 "Internet Server Error: Object/module not found." I'm leaning towards the idea that there is a permission issue somewhere at the root of the problem, but if this were the case, why wouldn't it say "You don't have permission"? I'd really like to rewrite the whole app but "they" won't let me.

  • Quaddratic Bezier Curve: Calculate Tangent

    - by stefan.at.wpf
    Hello, I have have a quadratic bezier curve and I want to calculate the slope of the tangent in a given point. For example, let it be the middlepoint of the quadratic bezier curve, therefore t=0.5 (please see the link below for a picture of this). I've calculated the first derivation of the formula for the quadratic bezier curve, however I get 400 as value for the slope, though it should be 0. Maybe I'm using the first derivation in a wrong way? I know I could also calculate the tangents using trigonometric functions, however I'd like to do it using the first derivation, shouldn't this be possible? Thanks for any hint! For clarification / please note: I'm interested in a general way to get the slope in a arbitrary given point on a quadratic bezier curve, not only to get the tangent in the start- and end point. A picture of my problem including the text above: http://cid-0432ee4cfe9c26a0.skydrive.live.com/self.aspx/%c3%96ffentlich/Quadratic%20Bezier%20Curve.pdf Thank you very much for any hint!

  • Another Marketing Conference, part one – the best morning sessions.

    - by Roger Hart
    Yesterday I went to Another Marketing Conference. I honestly can’t tell if the title is just tipping over into smug, but in the balance of things that doesn’t matter, because it was a good conference. There was an enjoyable blend of theoretical and practical, and enough inter-disciplinary spread to keep my inner dilettante grinning from ear to ear. Sure, there was a bumpy bit in the middle, with two back-to-back sales pitches and a rather thin overview of the state of the web. But the signal:noise ratio at AMC2012 was impressively high. Here’s the first part of my write-up of the sessions. It’s a bit of a mammoth. It’s also a bit of a mash-up of what was said and what I thought about it. I’ll add links to the videos and slides from the sessions as they become available. Although it was in the morning session, I’ve not included Vanessa Northam’s session on the power of internal comms to build brand ambassadors. It’ll be in the next roundup, as this is already pushing 2.5k words. First, the important stuff. I was keeping a tally, and nobody said “synergy” or “leverage”. I did, however, hear the term “marketeers” six times. Shame on you – you know who you are. 1 – Branding in a post-digital world, Graham Hales This initially looked like being a sales presentation for Interbrand, but Graham pulled it out of the bag a few minutes in. He introduced a model for brand management that was essentially Plan >> Do >> Check >> Act, with Do and Check rolled up together, and went on to stress that this looks like on overall business management model for a reason. Brand has to be part of your overall business strategy and metrics if you’re going to care about it at all. This was the first iteration of what proved to be one of the event’s emergent themes: do it throughout the stack or don’t bother. Graham went on to remind us that brands, in so far as they are owned at all, are owned by and co-created with our customers. Advertising can offer a message to customers, but they provide the expression of a brand. This was a preface to talking about an increasingly chaotic marketplace, with increasingly hard-to-manage purchase processes. Services like Amazon reviews and TripAdvisor (four presenters would make this point) saturate customers with information, and give them a kind of vigilante power to comment on and define brands. Consequentially, they experience a number of “moments of deflection” in our sales funnels. Our control is lessened, and failure to engage can negatively-impact buying decisions increasingly poorly. The clearest example given was the failure of NatWest’s “caring bank” campaign, where staff in branches, customer support, and online presences didn’t align. A discontinuity of experience basically made the campaign worthless, and disgruntled customers talked about it loudly on social media. This in turn presented an opportunity to engage and show caring, but that wasn’t taken. What I took away was that brand (co)creation is ongoing and needs monitoring and metrics. But reciprocally, given you get what you measure, strategy and metrics must include brand if any kind of branding is to work at all. Campaigns and messages must permeate product and service design. What that doesn’t mean (and Graham didn’t say it did) is putting Marketing at the top of the pyramid, and having them bawl demands at Product Management, Support, and Development like an entitled toddler. It’s going to have to be collaborative, and session 6 on internal comms handled this really well. The main thing missing here was substantiating data, and the main question I found myself chewing on was: if we’re building brands collaboratively and in the open, what about the cultural politics of trolling? 2 – Challenging our core beliefs about human behaviour, Mark Earls This was definitely the best show of the day. It was also some of the best content. Mark talked us through nudging, behavioural economics, and some key misconceptions around decision making. Basically, people aren’t rational, they’re petty, reactive, emotional sacks of meat, and they’ll go where they’re led. Comforting stuff. Examples given were the spread of the London Riots and the “discovery” of the mountains of Kong, and the popularity of Susan Boyle, which, in turn made me think about Per Mollerup’s concept of “social wayshowing”. Mark boiled his thoughts down into four key points which I completely failed to write down word for word: People do, then think – Changing minds to change behaviour doesn’t work. Post-rationalization rules the day. See also: mere exposure effects. Spock < Kirk - Emotional/intuitive comes first, then we rationalize impulses. The non-thinking, emotive, reactive processes run much faster than the deliberative ones. People are not really rational decision makers, so  intervening with information may not be appropriate. Maximisers or satisficers? – Related to the last point. People do not consistently, rationally, maximise. When faced with an abundance of choice, they prefer to satisfice than evaluate, and will often follow social leads rather than think. Things tend to converge – Behaviour trends to a consensus normal. When faced with choices people overwhelmingly just do what they see others doing. Humans are extraordinarily good at mirroring behaviours and receiving influence. People “outsource the cognitive load” of choices to the crowd. Mark’s headline quote was probably “the real influence happens at the table next to you”. Reference examples, word of mouth, and social influence are tremendously important, and so talking about product experiences may be more important than talking about products. This reminded me of Kathy Sierra’s “creating bad-ass users” concept of designing to make people more awesome rather than products they like. If we can expose user-awesome, and make sharing easy, we can normalise the behaviours we want. If we normalize the behaviours we want, people should make and post-rationalize the buying decisions we want.  Where we need to be: “A bigger boy made me do it” Where we are: “a wizard did it and ran away” However, it’s worth bearing in mind that some purchasing decisions are personal and informed rather than social and reactive. There’s a quadrant diagram, in fact. What was really interesting, though, towards the end of the talk, was some advice for working out how social your products might be. The standard technology adoption lifecycle graph is essentially about social product diffusion. So this idea isn’t really new. Geoffrey Moore’s “chasm” idea may not strictly apply. However, his concepts of beachheads and reference segments are exactly what is required to normalize and thus enable purchase decisions (behaviour change). The final thing is that in only very few categories does a better product actually affect purchase decision. Where the choice is personal and informed, this is true. But where it’s personal and impulsive, or in any way social, “better” is trumped by popularity, endorsement, or “point of sale salience”. UX, UCD, and e-commerce know this to be true. A better (and easier) experience will always beat “more features”. Easy to use, and easy to observe being used will beat “what the user says they want”. This made me think about the astounding stickiness of rational fallacies, “common sense” and the pathological willful simplifications of the media. Rational fallacies seem like they’re basically the heuristics we use for post-rationalization. If I were profoundly grimy and cynical, I’d suggest deploying a boat-load in our messaging, to see if they’re really as sticky and appealing as they look. 4 – Changing behaviour through communication, Stephen Donajgrodzki This was a fantastic follow up to Mark’s session. Stephen basically talked us through some tactics used in public information/health comms that implement the kind of behavioural theory Mark introduced. The session was largely about how to get people to do (good) things they’re predisposed not to do, and how communication can (and can’t) make positive interventions. A couple of things stood out, in particular “implementation intentions” and how they can be linked to goals. For example, in order to get people to check and test their smoke alarms (a goal intention, rarely actualized  an information campaign will attempt to link this activity to the clocks going back or forward (a strong implementation intention, well-actualized). The talk reinforced the idea that making behaviour changes easy and visible normalizes them and makes them more likely to succeed. To do this, they have to be embodied throughout a product and service cycle. Experiential disconnects undermine the normalization. So campaigns, products, and customer interactions must be aligned. This is underscored by the second section of the presentation, which talked about interventions and pre-conditions for change. Taking the examples of drug addiction and stopping smoking, Stephen showed us a framework for attempting (and succeeding or failing in) behaviour change. He noted that when the change is something people fundamentally want to do, and that is easy, this gets a to simpler. Coordinated, easily-observed environmental pressures create preconditions for change and build motivation. (price, pub smoking ban, ad campaigns, friend quitting, declining social acceptability) A triggering even leads to a change attempt. (getting a cold and panicking about how bad the cough is) Interventions can be made to enable an attempt (NHS services, public information, nicotine patches) If it succeeds – yay. If it fails, there’s strong negative enforcement. Triggering events seem largely personal, but messaging can intervene in the creation of preconditions and in supporting decisions. Stephen talked more about systems of thinking and “bounded rationality”. The idea being that to enable change you need to break through “automatic” thinking into “reflective” thinking. Disruption and emotion are great tools for this, but that is only the start of the process. It occurs to me that a great deal of market research is focused on determining triggers rather than analysing necessary preconditions. Although they are presumably related. The final section talked about setting goals. Marketing goals are often seen as deriving directly from business goals. However, marketing may be unable to deliver on these directly where decision and behaviour-change processes are involved. In those cases, marketing and communication goals should be to create preconditions. They should also consider priming and norms. Content marketing and brand awareness are good first steps here, as brands can be heuristics in decision making for choice-saturated consumers, or those seeking education. 5 – The power of engaged communities and how to build them, Harriet Minter (the Guardian) The meat of this was that you need to let communities define and establish themselves, and be quick to react to their needs. Harriet had been in charge of building the Guardian’s community sites, and learned a lot about how they come together, stabilize  grow, and react. Crucially, they can’t be about sales or push messaging. A community is not just an audience. It’s essential to start with what this particular segment or tribe are interested in, then what they want to hear. Eventually you can consider – in light of this – what they might want to buy, but you can’t start with the product. A community won’t cohere around one you’re pushing. Her tips for community building were (again, sorry, not verbatim): Set goals Have some targets. Community building sounds vague and fluffy, but you can have (and adjust) concrete goals. Think like a start-up This is the “lean” stuff. Try things, fail quickly, respond. Don’t restrict platforms Let the audience choose them, and be aware of their differences. For example, LinkedIn is very different to Twitter. Track your stats Related to the first point. Keeping an eye on the numbers lets you respond. They should be qualified, however. If you want a community of enterprise decision makers, headcount alone may be a bad metric – have you got CIOs, or just people who want to get jobs by mingling with CIOs? Build brand advocates Do things to involve people and make them awesome, and they’ll cheer-lead for you. The last part really got my attention. Little bits of drive-by kindness go a long way. But more than that, genuinely helping people turns them into powerful advocates. Harriet gave an example of the Guardian engaging with an aspiring journalist on its Q&A forums. Through a series of serendipitous encounters he became a BBC producer, and now enthusiastically speaks up for the Guardian community sites. Cultivating many small, authentic, influential voices may have a better pay-off than schmoozing the big guys. This could be particularly important in the context of Mark and Stephen’s models of social, endorsement-led, and example-led decision making. There’s a lot here I haven’t covered, and it may be worth some follow-up on community building. Thoughts I was quite sceptical of nudge theory and behavioural economics. First off it sounds too good to be true, and second it sounds too sinister to permit. But I haven’t done the background reading. So I’m going to, and if it seems to hold real water, and if it’s possible to do it ethically (Stephen’s presentations suggests it may be) then it’s probably worth exploring. The message seemed to be: change what people do, and they’ll work out why afterwards. Moreover, the people around them will do it too. Make the things you want them to do extraordinarily easy and very, very visible. Normalize and support the decisions you want them to make, and they’ll make them. In practice this means not talking about the thing, but showing the user-awesome. Glib? Perhaps. But it feels worth considering. Also, if I ever run a marketing conference, I’m going to ban speakers from using examples from Apple. Quite apart from not being consistently generalizable, it’s becoming an irritating cliché.

  • How can I tell if a user came to a page via a Google Adwords PPC campaign?

    - by Mike Crittenden
    I have a form with a hidden "Came from Adwords" field that will be marked true (via javascript) if the user came from a PPC campaign and will stay false if not. That way, when the user submits the form, we will have each submission stored with info about whether that submission came from adwords or not, all without the user knowing. How can I fetch this info? I know that Google sets a cookie called Conversion whenever you click a PPC link to a page, but the cookie's content is just random alphanumeric characters. Is there something in the Analytics/Adwords API that will let me test for this? Do I have to resort to adding ?ref=adwords or something onto the PPC URLs so that I can test that way?

  • Are there some general Network programming best practices?

    - by uriDium
    I am implementing some networking stuff in our project. It has been decided that the communication is very important and we want to do it synchronously. So the client sends something the server acknowledges. Are there some general best practices for the interaction between the client and the server. For instance if there isn't an answer from the server should the client automatically retry? Should there be a timeout period before it retries? What happens if the acknowledgement fails? At what point do we break the connection and reconnect? Is there some material? I have done searches but nothing is really coming up. I am looking for best practices in general. I am implementing this in c# (probably with sockets) so if there is anything .Net specific then please let me know too.

  • Returning the value of an identity column during/after INSERT command

    - by Adam Kane
    Using VS 2010, with ASP.NET, and .NET 3.0, and C#... When I use a System.Web.UI.WebControls.SqlDataSource and call its Insert() method to insert a new row, and that table has an identity column, I'd like my method to return the value of that column. For example, in my SQL 2005 table, I've got: Customer.Id Customer.FirstName Customer.LastName Where Customer.Id is an identity colum. When I call my method InsertNewCustomerRecord( "John", "Smith" ), I'd like to be able to return the Customer.Id that gets automatically generated in the database. Sorry for such a roughly posed question. Let me know if I can add better detail. Thanks.

  • Implementing Linked Lists in C#

    - by nijhawan.saurabh
    Why? The question is why you need Linked Lists and why it is the foundation of any Abstract Data Structure. Take any of the Data Structures - Stacks, Queues, Heaps, Trees; there are two ways to go about implementing them - Using Arrays Using Linked Lists Now you use Arrays when you know about the size of the Nodes in the list at Compile time and Linked Lists are helpful where you are free to add as many Nodes to the List as required at Runtime.   How? Now, let's see how we go about implementing a Simple Linked List in C#. Note: We'd be dealing with singly linked list for time being, there's also another version of linked lists - the Doubly Linked List which maintains two pointers (NEXT and BEFORE).   Class Diagram Let's see the Class Diagram first:     Code     1 // -----------------------------------------------------------------------     2 // <copyright file="Node.cs" company="">     3 // TODO: Update copyright text.     4 // </copyright>     5 // -----------------------------------------------------------------------     6      7 namespace CSharpAlgorithmsAndDS     8 {     9     using System;    10     using System.Collections.Generic;    11     using System.Linq;    12     using System.Text;    13     14     /// <summary>    15     /// TODO: Update summary.    16     /// </summary>    17     public class Node    18     {    19         public Object data { get; set; }    20     21         public Node Next { get; set; }    22     }    23 }    24         1 // -----------------------------------------------------------------------     2 // <copyright file="LinkedList.cs" company="">     3 // TODO: Update copyright text.     4 // </copyright>     5 // -----------------------------------------------------------------------     6      7 namespace CSharpAlgorithmsAndDS     8 {     9     using System;    10     using System.Collections.Generic;    11     using System.Linq;    12     using System.Text;    13     14     /// <summary>    15     /// TODO: Update summary.    16     /// </summary>    17     public class LinkedList    18     {    19         private Node Head;    20     21         public void AddNode(Node n)    22         {    23             n.Next = this.Head;    24             this.Head = n;    25     26         }    27     28         public void printNodes()    29         {    30     31             while (Head!=null)    32             {    33                 Console.WriteLine(Head.data);    34                 Head = Head.Next;    35     36             }    37     38         }    39     }    40 }    41          1 using System;     2 using System.Collections.Generic;     3 using System.Linq;     4 using System.Text;     5      6 namespace CSharpAlgorithmsAndDS     7 {     8     class Program     9     {    10         static void Main(string[] args)    11         {    12             LinkedList ll = new LinkedList();    13             Node A = new Node();    14             A.data = "A";    15     16             Node B = new Node();    17             B.data = "B";    18     19             Node C = new Node();    20             C.data = "C";    21             ll.AddNode(A);    22             ll.AddNode(B);    23             ll.AddNode(C);    24     25             ll.printNodes();    26         }    27     }    28 }    29        Final Words This is just a start, I will add more posts on Linked List covering more operations like Delete etc. and will also explore Doubly Linked List / Implementing Stacks/ Heaps/ Trees / Queues and what not using Linked Lists.   Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • Microsoft Sync Framework - How to reprovision a table (or entire scope) fater schema changes?

    - by Rabbi
    B"H I have already setup Syncing with Microsoft Sync Framework, and now I need to add fields to a table. How do I re-provision the databases? The setup is exceedingly simple: Two sql express 2008 servers The scope includes the entire database Using Microsoft Sync Framework 2.0 Synchronizing by direct access. Using the standard new SqlSyncProvider Do I make the structural changes at both ends? Or do I only change one Server and let Sync Framework somehow propagate the change? Do I need to delete the _tracking tables and/or the stored procedures? How about the triggers? Has anyone been using the Sync Framework? Please help.

  • Multi tenancy with Unity

    - by Savvas Sopiadis
    Hi everybody! I'm trying to implement this scenario using Unity and i can't figure out how this could be done: the same web application (ASP.NET MVC) should be made accessible to more than one client (multi-tenant). The URL of the web site will differentiate the client (this i know how to get). So getting the URL one could set the (let's call it) IConnectionStringProvider parameter (which will be afterward injected into IRepository and so on). Through which mechanism (using Unity) do i set the IConnectionStringProvider parameter at run time? I have done this in the past using Windsor & IHandlerSelector (see this) but it's my first attempt using Unity. Any help is deeply appreciated! Thanks in advance

  • UiElement based on another class

    - by plotnick
    I placed a control into a grid. let's say the control is derived from public class 'ButBase' which is derived in its turn from System.Windows.Controls.Button. The code normally compiles and app works just fine. But there's something really annoying. When you try to switch to xaml-design tab it will say 'The document root element is not supported by the visual designer', which is normal and I'm totally okay with that, but the thing is, that all the xaml code is underlined and VS2010 says: 'Cannot create an instance of ButBase' although still normally compiles and able to run. I've tried the same code in VS2008, it said that needs to see a public parameterless constructor in the ButBase, and even after I put one it showed the same error. What do I miss here?

  • django-admin - how to modify ModelAdmin to create multiple objects at once?

    - by skrobul
    let's assume that I have very basic model class Message(models.Model): msg = models.CharField(max_length=30) this model is registered with admin module: class MessageAdmin(admin.ModelAdmin): pass admin.site.register(Message, MessageAdmin) Currently when I go into the admin interface, after clicking "Add message" I have only one form where I can enter the msg. I would like to have multiple forms (formset perhaps) on the "Add page" so I can create multiple messages at once. It's really annoying having to click "Save and add another" every single time. Ideally I would like to achieve something like InlineModelAdmin but it turns out that you can use it only for the models that are related to the object which is edited. What would you recommend to use to resolve this problem?

  • Copy task in Visual Studio 2008

    - by Maurizio Reginelli
    This is a question related to a previous question I posted (see here). I need to configure a .csproj file to copy some files from a directory to another one (let me call them SOURCE and DESTINATION). I also need to change the SOURCE path depending from the configuration I'm using. For example, if I compile my project in Debug mode, the SOURCE path must contain a subfolder called Debug. I tried the solution proposed by Schmitt in the previous post, using $(ConfigurationName) to set the dynamic directory into the SOURCE path. When I opened the solution containing that project, a list of links to the source files appeared in the main tree of the project and they were correctly related to the Debug mode. But when I changed to the Release mode, I saw that the path of the linked source files were set again to the Debug version. Is there a way to specify a parameter in the Include attribute of the SourceFiles element? Thank you.

  • Collection.contains(Enum.Value) in HQL?

    - by Seth
    I'm a little confused about how to do something in HQL. So let's say I have a class Foo that I'm persisting in hibernate. It contains a set of enum values, like so: public class Foo { @CollectionOfElements private Set<Bar> barSet = new HashSet<Bar>(); //getters and setters here ... } and public enum Bar { A, B } Is there an HQL statement I can use to fetch only Foo instances who'se barSet containst Bar.B? List foos = session.createQuery("from Foo as foo " + "where foo.barSet.contains.Bar.B").list(); Or am I stuck fetching all Foo instances and filtering them out at the DAO level? List foos = session.createQuery("from Foo as foo").list(); List results = new ArrayList(); for(Foo f : foos) { if(f.barSet.contains(Bar.B)) results.add(f); } Thanks!
