• iphone mkmapview

  - by karthik

  Hi, This is karthik. I am developing an app using mapview in iphone. I have to use two different pins to show user locations. That two users are different type . One user is belong to some category and another one is some other category. I have to check that category and want to plot pin depend upon that category. When I try to do that, that pin is not showing properly. For a certain category it shows another pin, not what i set there. Can anyone help me? What i need is i want to load two different pins in map depend upon some category. For example , if that category is shopping mall then i have to show building image then if there is any garden i have to show some other image at a same time not one by one . I want to plot two pins with different category at the same time. For that,what could i do? I tried lot of solution , but its not showing properly. Help me?

• jQuery .load() and sub-pages

  - by user354051

  Hi, I am not just a newbie with Javascript. I am developing a simple site to get my hands on web programming. The web site is simple and structure is like this: A simple ul/li/css based navigation menu Sub pages are loaded in "div" using jQuery, when ever user click appropriate menu item. Some of the sub-pages are using different jQuery based plugins such as LightWindow, jTip etc. The jQuery function that loads the sub-page is like this: function loadContent(htmlfile){ jQuery("#content").load(htmlfile); }; The menu items fires loadContent method like this: <li><a href="javascript:void(0)" onclick="loadContent('overview.html');return false">overview</a></li> This loads a sub-page name "overview.html" inside the "div". That's it. Now this is working fine but some of the sub-pages using jQuery based plugins are not working well when loaded inside the "div". If you load them individually in the browser they are working fine. Based on above I have few qustions: Most of the plugins are based on jQuery and sub-pages are loaded inside the "index.html" using "loadContent" function. Do I have to call <script type="text/javascript" src="js/jquery-1.4.2.min.js"></script> on each and every sub-page? If a page is using a custom jQuery plugin, then where do I call it? In "index.html" or on the page where I am using it? I think what ever script you will call in "index.html", you don't to have call them again in any of the sub pages you are using. Am I right here? Thanks Prashant

• Can I have two separate projects, 1 WebForms and 1 ASP.NET MVC, to both point to the same domain?

  - by Hamman359

  Is it possible to setup two separate projects, 1 WebForms and 1 ASP.NET MVC, to both point to the same domain? i.e. both point to different pages within www.somesite.com. Here's some background on the application and why I'm asking. This is a brownfield application that is currently 2.0 WebForms and is full of WebFormy 'goodness' (i.e. ObjectDataSources, FormView controls, UpdatePanels, etc...) There are lost of other 'fun' things in the code base like 600+ Stored Procedures and 200+ line methods in the business layer code that get data from the DB via stored proc, do some processing on the data, build an HTML string using string concatenation and then return that string to the UI layer. What we are planning on doing is developing new features in MVC and slowly converting the existing features over to MVC one at a time. As part of this transition, we will also be re-writing the layers below the UI to clean up the mess there and to do things like replace the stored procedures with NHibernate and introduce an IOC container. I know that you can run WebForms and MVC side-by-side in the same project, however, because we will be making wholesale changes to the way we do many things throughout our entire development stack, I'd like the new stuff to be a completely separate project within the solution. This should help serve as very visual reminder that this is a different way of doing things than before and make it easier to remove the old code as it is no longer needed. What I don't know is, is this even possible? Can two separate project point to the same domain? Here's an quick example of what I'm thinking: www.somesite.com/orders.aspx?id=123 (Orders page from existing WebForms project) www.somesite.com/customer/987 (Customer page from new MVC project)

• JOAL with JNLPAppletLauncher Problem

  - by user347445

  Hi, I am developing a Java Applet that makes use of JOAL.

Any ideas how I could fix this? Thank you very much.

• How do I copy or move an NSManagedObject from one context to another?

  - by Aeonaut

  I have what I assume is a fairly standard setup, with one scratchpad MOC which is never saved (containing a bunch of objects downloaded from the web) and another permanent MOC which persists objects. When the user selects an object from scratchMOC to add to her library, I want to either 1) remove the object from scratchMOC and insert into permanentMOC, or 2) copy the object into permanentMOC. The Core Data FAQ says I can copy an object like this: NSManagedObjectID *objectID = [managedObject objectID]; NSManagedObject *copy = [context2 objectWithID:objectID]; (In this case, context2 would be permanentMOC.) However, when I do this, the copied object is faulted; the data is initially unresolved. When it does get resolved, later, all of the values are nil; none of the data (attributes or relationships) from the original managedObject are actually copied or referenced. Therefore I can't see any difference between using this objectWithID: method and just inserting an entirely new object into permanentMOC using insertNewObjectForEntityForName:. I realize I can create a new object in permanentMOC and manually copy each key-value pair from the old object, but I'm not very happy with that solution. (I have a number of different managed objects for which I have this problem, so I don't want to have to write and update copy: methods for all of them as I continue developing.) Is there a better way?

• SqlBackup from my client app

  - by Robbert Dam

  I have an client app that runs on several machines, and connects to a single SQL database. On the client app, the user has the possiblity to use a local SQL (CE) database or connect to a remote SQL database. There is also a box where a backup location can be set. For the backup of the remote SQL database I use the following code: var bdi = new BackupDeviceItem(backupFile, DeviceType.File); var backup = new Backup { Database = "AppDb", Initialize = true }; backup.Devices.Add(bdi); var server = new Server(connection); backup.SqlBackup(server); When developing my application, I wasn't aware that the given backupFile is written on the machine where the SQL server runs! And not on the client machine. What I want is "dump" all the data from my database to a local file. (Why? Because users may enter a network location in the "backup location" box, and backing up SQL immediately to a network location fails. So need to write local first and then copy to the network in that case.) I there an alternative to the method above?

• How to assign .net membership roles to individual database records

  - by mdresser

  I'm developing a system where we want to restrict the availability of information displayed to users based on their roles. e.g. I have a tabled called EventType (ID, EventTypeDescription) which contains the following records: 1, 'Basic Event' 2, 'Intermediate Event' 3, 'Admin Event' What I need to achieve is to filter the records returned based on the username (and hence role) of the logged-in user. e.g if an advanced user is logged in they will see all the event types, if the standard user is logged in they will only see the basic event type etc. Ideally id like to do this in a way which can be easily extended to other tables as necessary. So I'd like to avoid simply adding a 'Roles' field to each table where the data is user context sensitive. One idea I'm thinking of is to create some kind of permissions table like: PermissionsTable ( ID, Aspnet_RoleId, TableName, PrimaryKeyValue ) this has the drawback of using this is obviously having to use the table name to switch which table to join onto. Edit: In the absence of any better suggestions, I'm going to go with the last idea I mentioned, but instead of having a TableName field, I'm going to normalise the TableName out to it's own table as follows: TableNames ( ID, TableName ) UserPermissionsTable ( ID, Aspnet_UserId, TableID, PrimaryKeyValue )

• What's the best way to develop a debugging window for an ajax ASP.Net MVC application

  - by KallDrexx

  While developing my ASP.NET MVC, I have started to see the need for a debugging console window to assist in figuring out what is going right and wrong in my code. I read the last few chapters of the Pro Asp.net MVC book, and the author details how to use http modules to show page load/creation times and linq to sql query logs, both of which I definitely want to be able to see. However, since I am loading a lot of small sections of my page individually with ajax I don't want the debug information right there in the middle of my screen. So the idea I came up with was to have a separate browser window (open-able by a link or some javascript) with a console log, that can contain logged entries both from javascript and from the asp.net mvc run. The former should be relatively easy, but I'm having trouble coming up with a way to log the asp.net information in ajax requests. The direction I have been thinking of going is to create an httpmodule (like the Pro MVC book does), and have that module contain some that append the javascript's log to console calls with the messages. The issue I see with this is finding a way to get the log messages from the controller's action methods to the httpmodule's methods. The only way I see to do this is with a singleton, but I'm not sure if singletons are bad practice for a stateless web application. Furthermore, it seems like if I return json with my ajax calls (instead of pure html) then that won't work at all anyways and unless there is a way to add data to an existing json structure inside the httpmodule. How does everyone else handle this type of debugging in heavily ajax applications? For reference, the javascript library I am using is jquery.

• Setting up a multi-site CMS, collecting thoughts about the DB schema

  - by Ben Fransen

  Hello all, I'm collecting some thoughts about creating a multisite CMS. In my opinion there are two major approaches. All data is stored into 1 database, giving me the advantage of single point of updates; Seperated databases, so each client has its own database. Giving me the advantage to measure bandwith. Option 1 gives me the disadvantage of measuring bandwith while option is giving me the disadvantage of a single point of update structure. Are there any generic approaches for creating a sort of update system? So my clients can download a small package (maybe a zip with a conf file to tell the updatescript where to put all the files and how to extend the database??) Do you guys have some thougths about the best solution for a situation like this? I have my own webserver, full access to all resources and I'm developing in PHP with MySQL as DBMS. I hope to hear from you and I surely appreciate any effort you make to help me further! Greets from Holland, Ben Fransen

• PHP - Database schema: version control, branching, migrations.

  - by Billiam

  I'm trying to come up with (or find) a reusable system for database schema versioning in php projects. There are a number of Rails-style migration projects available for php. http://code.google.com/p/mysql-php-migrations/ is a good example. It uses timestamps for migration files, which helps with conflicts between branches. General problem with this kind of system: When development branch A is checked out, and you want to check out branch B instead, B may have new migration files. This is fine, migrating to newer content is straight forward. If branch A has newer migration files, you would need to migrate downwards to the nearest shared patch. If branch A and B have significantly different code bases, you may have to migrate down even further. This may mean: Check out B, determine shared patch number, check out A, migrate downwards to this patch. This must be done from A since the actual applied patches are not available in B. Then, checkout branch B, and migrate to newest B patch. Reverse process again when going from B to A. Proposed system: When migrating upwards, instead of just storing the patch version, serialize the whole patch in database for later use, though I'd probably only need the down() method. When changing branches, compare patches that have been run to patches that are available in the destination branch. Determine nearest shared patch (or oldest difference, maybe) between db table of run patches and patches in destination branch by ID or hash. Could also look for new or missing patches that are buried under a number of shared patches between the two branches. Automatically merge down to the nearest shared patch, using the db table stored down() methods, and then merge up to the branche's latest patch. My question is: Is this system too crazy and/or fraught with consequences to bother developing? My experience with database schema versioning is limited to PHP autopatch, which is an up()-only system requiring filenames with sequential IDs.

• TextBox doesn't fire TextChanged Event on IE 8, AutoPostback is true

  - by MaikoID

  Hi guys, I have the same thing, there are many TextBoxes with the event TextChanged set and with AutoPostback = true, and works in all browsers (Chrome, Opera, Firefox 3.6) except in IE 8, IE 6/7 I didn't test. I don't want to put the onblur event in all my TextBoxs because there are many pages with many TextBox that use this event. Description I'm using a masterPage, in the aspx i have <asp:TextBox ID="txtCnpj" runat="server" CssClass="txt" Width="200px" onkeyup="Mascara(this,Cnpj)" onkeydown="Mascara(this,Cnpj)" MaxLength="18" AutoPostBack="true" ValidationGroup="txtCnpj" OnTextChanged="txtCnpj_TextChanged"></asp:TextBox> in the aspx.cs protected void txtCnpj_TextChanged(object sender, EventArgs e) { if (CredorInvestimento.GetCredorInvestimento(txtCnpj.Text) != null) { ((TextBox)sender).Text = ""; ((TextBox)sender).Focus(); rfvCnpj.ErrorMessage = "Duplicado"; Page.Validate(txtCnpj.ID); } else txtNome.Focus(); } Thanks! ps: I really doesn't like of asp.net I spend more time fixing errors than developing new functions. ps: sorry for my english. ps: if i remove the onkeydown and onkeyup events the textchanged fire in IE, but i realy this events too.

• Modify Executing Jar file

  - by pinkynobrain

  Hello Stack Overflow friends. I have a simple problem which i fear doesnt have a simple solution and i need advice as to how to proceed. I am developing a java application packaged as and executable JAR but it requires to modify some of its JAR file contents during execution. At this stage i hit a problem because some OS lock the file preventing writes to it. It is essential that the user sees an updated version of the jar file by the time the application exits allthough i can be pretty flexible as to how to achieve this. A clean and efficient solution is obviously prefereable but portability is the only hard requirement. The following are three approaches i can see to solving the problem, feel free to comment on them or suggest others. Tell Java to unlock the JAR file for writing(this doesnt seem possible but it would be the easyest solution) Copy the executable class files to a tempory file on application startup, use a class loader to load these files and unload the ones from the initial JAR file.(Not had much experience with the classloaders but hopefully the JVM would then be smart enough to realize that the original JAR is nolonger in use and so unlock it) Put a Second executable JAR File inside the First, on startup extract the inner jar to e temporaryfile, invoke a new java process and pass it the location of the Outer JAR, first process exits, second process modifys the Outer jar unincumbered.(This will work but im not sure there is a platform independant way of one java app invoking another) I know this is a weird question but any help would be appreciated.

  Hello .. I am new to java and also cygwin . I do not have in detailed knowledge of both . I need some help.. I simple steps i will try to explain my problem. 1) I am working on tinyOS . its open source OS , used for wireless sensor networks. It provides java libraries to work on communication (PC to sensor) 2) I am working on windows xp environment through cigwin. 3) I am developing an application . THis application requires one java interface called "Serial Forwarder" , which is readily available in libraries provided. Previously i used to start this interface manually (by entering command *"java net.tinyos.sf.SerialForwarder ")*and then my application which uses this interface. But now i want to make my application independent . User need know about this background cygwin commands . 4) So in my java application i used "Runtime.getRuntime().exec( "java net.tinyos.sf.SerialForwarder)" . 5) This i neither giving any error nor starting the interface. Am I going on right way ? When i am using runtime execute command , how can i make sure that this command is called through cigwin interface ? Also .. if i want to write .bat file .. i which i can give commands which will be executed .. how can i make sure that those commands are given through cigwin .. and not through cmd.exe ..

• Problem with RVM and gem that has an executable

  - by djhworld

  Hi there, I've recently made the plunge to use RVM on Ubuntu. Everything seems to have gone swimmingly...except for one thing. I'm in the process of developing a gem of mine that has a script placed within its own bin/ directory, all of the gemspec and things were generated by Jeweler. The bin/mygem file contains the following code: - #!/usr/bin/env ruby begin require 'mygem' rescue LoadError require 'rubygems' require 'mygem' end app = MyGem::Application.new app.run That was working fine on the system version of Ruby. Now...recently I've moved to RVM to manage my ruby versions a bit better, except now my gem doesn't appear to be working. Firstly I do this: - rvm 1.9.2 Then I do this: - rvm 1.9.2 gem install mygem Which installs fine, except...when I try to run the command for mygem mygem I just get the following exception: - daniel@daniel-VirtualBox:~$ mygem <internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- mygem (LoadError) from <internal:lib/rubygems/custom_require>:29:in `require' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/gems/mygem-0.1.4/bin/mygem:2:in `<top (required)>' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `load' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `<main>'mygem NOTE: I have a similar RVM setup on MAC OSX and my gem works fine there so I think this might be something to do with Ubuntu?

• Testing system where App-level and Request-level IoC containers exist

  - by Bobby

  My team is in the process of developing a system where we're using Unity as our IoC container; and to provide NHibernate ISessions (Units of work) over each HTTP Request, we're using Unity's ChildContainer feature to create a child container for each request, and sticking the ISession in there. We arrived at this approach after trying others (including defining per-request lifetimes in the container, but there are issues there) and are now trying to decide on a unit testing strategy. Right now, the application-level container itself is living in the HttpApplication, and the Request container lives in the HttpContext.Current. Obviously, neither exist during testing. The pain increases when we decided to use Service Location from our Domain layer, to "lazily" resolve dependencies from the container. So now we have more components wanting to talk to the container. We are also using MSTest, which presents some concurrency dilemmas during testing as well. So we're wondering, what do the bright folks out there in the SO community do to tackle this predicament? How does one setup an application that, during "real" runtime, relies on HTTP objects to hold the containers, but during test has the flexibility to build-up and tear-down the containers consistently, and have the ServiceLocation bits get to those precise containers. I hope the question is clear, thanks!

• Declaration of arrays before "normal" variables in c?

  - by bjarkef

  Hi We are currently developing an application for a msp430 MCU, and are running into some weird problems. We discovered that declaring arrays withing a scope after declaration of "normal" variables, sometimes causes what seems to be undefined behavior. Like this: foo(int a, int *b); int main(void) { int x = 2; int arr[5]; foo(x, arr); return 0; } foo sometimes is passed a pointer as the second variable, that does not point to the arr array. We verify this by single stepping through the program, and see that the value of the arr variable in the main scope is not the same as the value of the b pointer variable in the foo scope. And no, this is not really reproduceable, we have just observed this behavior once in a while. Changing the example seems to solve the problem, like this: foo(int a, int *b); int main(void) { int arr[5]; int x = 2; foo(x, arr); return 0; } Does anybody have any input or hints as to why we experience this behavior? Or similar experiences? The MSP430 programming guide specifies that code should conform to the ANSI C89 spec. and so I was wondering if it says that arrays has to be declared before non-array variables? Any input on this would be appreciated.

• How much business logic belongs in RIA services layer?

  - by jkohlhepp

  I have been experimenting recently with Silverlight, RIA Services, and Entity Framework using .NET 4.0. I'm trying to figure out if that stack makes sense for use in any of my upcoming projects. It certainly seems like these technologies can be very productive for developing applications, but I'm struggling to decide how an application on top of this stack should be architected. The main issue I have is that in most of the demos I've seen most of the business logic ends up as DataAnnotations and custom validations in the RIA Services domain service class. This seems inappropriate to me. I view the domain service as basically a glorified web service that happens to make it easy to push information to the client. But most of what I've seen seems to orient the domain service as the main source of business logic in the application. So, my questions: What is the best location for business logic (rules, validations, behaviors, authorization) in an application using this stack? Are there any guidelines published at an architectural level for using this stack? My questions pertain to large, complex, and long-lived applications. Obviously for an application of only a few screens this is less of a concern. Edit: Another thing I meant to mention is that obviously you can make the domain service class stupid, but then you lose a lot of the automagic entity information (e.g. validations) being pushed to the client. And then if you lose that is there any point to using RIA services?

• How to get the "real" colors when exporting a GDI drawing to bmp

  - by Rodrigo

  Hi guys I'm developing a ASP.Net web handler that returns images making a in-memory System.Windows.Forms.Control and then exports the rendered control as a bitmap compressed to PNG, using the method DrawToBitmap(). The classes are fully working by now, except for a problem with the color assignment. By example, this is a Gauge generated by the web handler. The colors assigned to the inner parts of the gauge are red (#FF0000), yellow (#FFFF00) and green (#00FF00) but I only get a dully version of each color (#CB100F for red, #CCB70D for yellow and #04D50D for green). The background is a bmp file containing the color gradient. The color loss happens whether the background is a gradient as the sample, a black canvas, a white canvas, a transparent canvas, even when there is not a background set. With black background With transparent background With a white background Without a background set With pixel format in Format32bppArgb I've tried multiple bitmap color deeps, output formats, compression level, etc. but none of them seems to work. Any ideas? This is a excerpt of the source code: Bitmap bmp = new Bitmap(w, h, System.Drawing.Imaging.PixelFormat.Format32bppPArgb); Image bgimage = (Image) HttpContext.GetGlobalResourceObject("GraphicResources", "GaugeBackgroundImage"); Canvas control_canvas = new Canvas(); .... //the routine that makes the gauge .... control_canvas.DrawToBitmap(bmp, new Rectangle(0, 0, w, h));

• Web Automation Tool

  - by Aaron

  I've realized I need a full-fledged browser automation tool for testing user interactions with our JavaScript widget library. I was using qunit, starting with unit testing and then I unwisely started incorporating more and more functional tests. That was a bad idea: trying to simulate a lot of user actions with JavaScript. The timing issues have gotten out of control and have made the suite too brittle. Now I spend more time fixing the tests, then I do developing. Is it possible to find a browser automation tool that works in: Windows XP: IE6,7,8, FF3 OSX: Safari, FF3 ? I've looked into SeleniumIDE and RC, but there seems to be some IE8 problems. I've also seen some things about Google's WebDriver, which confusingly seems to work with Selenium. Our organziation has licenses for IBM's Rational Functional Tester, but I don' think that will work on the MAC. The idea is to try to run tests on all the browsers our organization supports. Doable? Are my requirements unrealistic? Any recommendations as far as software to try? Thanks!

• Initialize webservice WSDL at runtime using Flex and Mate framework

  - by GroovyB

  I am developing a Flex application on top of Mate framework. In this application, I am using a webservice to retrieve data. As this webservice as not a fix location URL (depending on where customers installed it), I define this URL in a config file. When the Flex application starts, it first reads this config file, then I would like to use the value I found to initialize the webservice. But currently, I have no idea how to this. Here is my EventMap.mxml <EventMap> <services:Services id="services" /> <EventHandlers type="{FlexEvent.PREINITIALIZE}"> <HTTPServiceInvoker instance="{services.configService}"> <resultHandlers> <MethodInvoker generator="{ConfigManager}" method="loadFromXml" arguments="{resultObject}" /> </resultHandlers> <faultHandlers> <InlineInvoker method="Alert.show" arguments="ERROR: Unable to load config.xml !" /> </faultHandlers> </HTTPServiceInvoker> In this part, the ConfigManager parse the config file and intitialize a bindable property called webServiceWsdl Here is my Services.mxml <mx:Object> <mx:Script> <![CDATA[ [Bindable] public var webservice:String; ]]> </mx:Script> <mx:HTTPService id="configService" url="config.xml" useProxy="false" /> <mx:WebService id="dataService" wsdl="{webservice}" useProxy="false"/> </mx:Object> How can I initialize this webservice property ?

• Best way to enforce inter-table constraints inside database

  I looking for the best way to check for inter-table constraints an step forward of foreing keys. For instance, to check if a date child record value is between a range date on two parent rows columns. For instance: Parent table ID DATE_MIN DATE_MAX ----- ---------- ---------- 1 01/01/2009 01/03/2009 ... Child table PARENT_ID DATE ---------- ---------- 1 01/02/2009 1 01/12/2009 <--- HAVE TO FAIL! ... I see two approaches: Create materialized views on-commit as shown in this article (or other equivalent on other RDBMS). Use stored-procedures and triggers. Any other approach? Which is the best option? UPDATE: The motivation of this question is not about "putting the constraints on database or on application". I think this is a tired question and anyone does the way she loves. And, I'm sorry for detractors, I'm developing with constraints on database. From here, the question is "which is the best option to manage inter-table constraints on database?". I'm added "inside database" on the question title. UPDATE 2: Some one added the "oracle" tag. Of course materialized views are oracle-tools but I'm interested on any option regardless it's on oracle or others RDBMSs.

• Career Plan: The one year plan. The three year plan.

  - by drelihan

  Hi Folks, I work as a developer however I only recently began developing full time having worked for 5 years in various roles. When it comes to career planning I think I pretty much agree with The Journeyman to Craftsman model coined in The Pragmatic Probrammer and used by Bob Martin. I see myself as a journeyman and I won't call myself a "good" (for want of a better word) until I re-evaluate my skills in 5 years time. However, as part of our careers we are encouraged to make one and three year plan with specific goals that we should hit. Unfortunately, my goal is this: Write clean code that solves a problem and is easy to maintain. From a technology point of view I want to know C++ and .net programming inside out(C#, WCF etc..) But that's it. That's my plan. Is this enough? So although there's a great discussion on what people should do with their career: http://stackoverflow.com/questions/11313/career-planning-any-tips My question is this: What's your one year plan? What's your three year plan? And am I being naive with my career? Thanks,

• A copy of ApplicationController has been removed from the module tree but is still active

  - by Matchu

  Whenever two concurrent HTTP requests go to my Rails app, the second always returns the following error: A copy of ApplicationController has been removed from the module tree but is still active! From there it gives an unhelpful stack trace to the effect of "we went through the standard server stuff, ran your first before_filter on ApplicationController (and I checked; it's just whichever filter runs first)", then offers the following: /home/matchu/rails/torch/vendor/rails/activesupport/lib/active_support/dependencies.rb:414:in `load_missing_constant' /home/matchu/rails/torch/vendor/rails/activesupport/lib/active_support/dependencies.rb:96:in `const_missing' which I'm assuming is a generic response and doesn't really say much. Google seems to tell me that people developing Rails Engines will encounter this, but I don't do that. All I've done is upgrade my Rails app from 2.2 (2.1?) to 2.3. What are some possible causes for this error, and how can I go about tracking down what's really going on? I know this question is vague, so would any other information be helpful? More importantly: I tried doing a test run in a "production" environment just now, and the error doesn't seem to persist. Does this only affect development, then, and need I not worry too much?

• How to avoid chaotic ASP.NET web application deployment?

  - by emzero

  Ok, so here's the thing. I'm developing an existing (it started being an ASP classic app, so you can imagine :P) web application under ASP.NET 4.0 and SQLServer 2005. We are 4 developers using local instances of SQL Server 2005 Express, having the source-code and the Visual Studio database project This webapp has several "universes" (that's how we call it). Every universe has its own database (currently on the same server) but they all share the same schema (tables, sprocs, etc) and the same source/site code. So manually deploying is really annoying, because I have to deploy the source code and then run the sql scripts manually on each database. I know that manual deploying can cause problems, so I'm looking for a way of automating it. We've recently created a Visual Studio Database Project to manage the schema and generate the diff-schema scripts with different targets. I don't have idea how to put the pieces together I would like to: Have a way to make a "sync" deploy to a target server (thanksfully I have full RDC access to the servers so I can install things if required). With "sync" deploy I mean that I don't want to fully deploy the whole application, because it has lots of files and I just want to deploy those new or changed. Generate diff-sql update scripts for every database target and combine it to just 1 script. For this I should have some list of the databases names somewhere. Copy the site files and executing the generated sql script in an easy and automated way. I've read about MSBuild, MS WebDeploy, NAnt, etc. But I don't really know where to start and I really want to get rid of this manual deploy. If there is a better and easier way of doing it than what I enumerated, I'll be pleased to read your option. I know this is not a very specific question but I've googled a lot about it and it seems I cannot figure out how to do it. I've never used any automation tool to deploy. Any help will be really appreciated, Thank you all, Regards
