• How do I make software that preserves database integrity and correctness?

  - by user287745

  I have made an application project in Visual Studio 2008 C#, SQL Server from Visual Studio 2008. The database has like 20 tables and many fields in each. I have made an interface for adding deleting editing and retrieving data according to predefined needs of the users. Now I have to Make to project into software which I can deliver to my professor. That is, he can just double click the icon and the software simply starts. No Visual Studio 2008 needed to start the debugging. The database will be on one powerful computer (dual core latest everything Windows XP) and the user will access it from another computer connected using LAN. I am able to change the connection string to the shared database using Visual Studio 2008/ debugger whenever the server changes but how am I supposed to do that when it's software? There will by many clients. Am I supposed to give the same software to every one, so they all can connect to the database? How will the integrity and correctness of the database be maintained? I mean the db.mdf file will be in a folder which will be shared with read and write access. So it's not necessary that only one user will write at a time. So is there any coding for this or?

• Open a buffer as a vertical split in VIM

  - by alfredodeza

  If you are editing a file in VIM and then you need to open an existing buffer (e.g. from your buffer list: :buffers) how can you open it in a vertical split? I know that you already can open it with a normal split like: :sbuffer N Wehere N is the buffer number you want, however, the above opens that N buffer horizontally, not vertically. I'm also aware that you can change the window placement after opening and have a Vertical Split like so: Ctrl-W H Ctrl-W L Which will vertically split the window to the right or the left. It seems to me that if there is a sbuffer there should be a vsbuffer but that doesn't exist (not that I am aware of) Also, please note that I am not looking for a plugin to solve this question. I know about a wealth of plugins that will allow you to do this. I am sure I might be missing something that is already there. EDIT: In the best spirit of collaboration, I have created a simple Function with a Mapping if someone else stumbles across this issue and do not want to install a plugin: Function: " Vertical Split Buffer Function function VerticalSplitBuffer(buffer) execute "vert belowright sb" a:buffer endfunction Mapping: " Vertical Split Buffer Mapping command -nargs=1 Vbuffer call VerticalSplitBuffer(<f-args>) This accomplishes the task of opening a buffer in a right split, so for buffer 1, you would call it like: :Vbuffer 1

• How to make UIButton work like Launcher in SpringBoard, when pressed for long timeinterval

  - by KayKay

  In my ViewController I am using UIButton which triggers some action when touchedUpInside. Upto here no problem, but i also want to add another action for touchDown event. More precisely i dont have an idea how to add that action to which event, that will work the same as when App-Icon is pressed longer in springboard which causes springboard enter in editing mode.Actually what i want is : when this button is kept holding for ,say about 2 seconds it will pop-up an alertView without touch being heldUp (with finger is still on button). I have tried with 2 NSdate difference, one of which is allocated when touchedDown and other when touchUpInside. Its working and popping alert,but only after touchedUpInside. I want it to show alert without touch being removed. Here is the code. (IBAction)touchedDown:(id)sender { momentTouchedDown = [[NSDate alloc] init];//class variable NSLog(@"touched down"); } - (IBAction)touchUpInside:(id)sender { NSLog(@"touch lifted Up\n"); NSDate *momentLifted = [[NSDate alloc] init]; double timeInterval = [momentLifted timeIntervalSinceDate:momentTouchedDown]; NSLog(@"time lifted = %@, time down = %@, time diff = %@", momentLifted, momentTouchedDown, [NSString stringWithFormat:@"%g",timeInterval]); [momentLifted release]; if(timeInterval > 2.0) { NSLog(@"AlertBox has been fired"); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Yes" message:@""//msg delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK" , nil]; [alert show]; [alert release]; } } Please provide me an insight..thanks for help in advance.

• In Python BeautifulSoup How to move tags

  - by JJ

  I have a partially converted XML document in soup coming from HTML. After some replacement and editing in the soup, the body is essentially - <Text...></Text> # This replaces <a href..> tags but automatically creates the </Text> <p class=norm ...</p> <p class=norm ...</p> <Text...></Text> <p class=norm ...</p> and so forth. I need to "move" the <p> tags to be children to <Text> or know how to suppress the </Text>. I want - <Text...> <p class=norm ...</p> <p class=norm ...</p> </Text> <Text...> <p class=norm ...</p> </Text> I've tried using item.insert and item.append but I'm thinking there must be a more elegant solution. for item in soup.findAll(['p','span']): if item.name == 'span' and item.has_key('class') and item['class'] == 'section': xBCV = short_2_long(item._getAttrMap().get('value','')) if currentnode: pass currentnode = Tag(soup,'Text', attrs=[('TypeOf', 'Section'),... ]) item.replaceWith(currentnode) # works but creates end tag elif item.name == 'p' and item.has_key('class') and item['class'] == 'norm': childcdatanode = None for ahref in item.findAll('a'): if childcdatanode: pass newlink = filter_hrefs(str(ahref)) childcdatanode = Tag(soup, newlink) ahref.replaceWith(childcdatanode) Thanks

• Best terminal environment for Cygwin/Windows?

  - by Anders Sandvig

  Today I run Cygwin with rxvt using the following startup line: rxvt -bg black -sl 8192 -fg white -sr -g 150x56 -fn "Fixedsys" -e /usr/bin/bash --login -i This gives me a resizeable native Windows window which is much better than the standard "DOS box" the default cygwin.bat provides. However, the current configuration does have a couple of issues: I am not able to enter non-ASCII characters into the terminal window (i.e. æ, ø, å and Æ, Ø, Å, which I use semi-frequently. In fact, the terminal will not even accept them when I paste them into the window. If I paste a string like "bølle" (Norwegian for "bulley"), all I get is "blle". I am not able to render UTF-8 character, they only show as ?, even if they are supported by the font (i.e. when rendering the same characters in ISO-8859-1 they show just fine.). I am running English Windows Vista with locale and keyboard layout set to Norwegian (ISO-8859-1 character set?), but I've had the exact same issue on Windows 2000 and XP. Anyone knows how to fix this (i.e. a better way to configure rxvt)? Apart from the issues mentioned above, I'm very happy with rxvt, so if I find a way to resolve them I'd like to continue using it. However, if the issues are not (easily) solvable, are the any other good terminal solutions for Cygwin? Update The solution provided by Andy and Mattias (editing the .inputrc file) did solve the input problem, but output rendering is still an issue. Output is fine when I render in ISO-8859-1, but when using UTF-8 I only get ? for non-ASCII characters. This behavior is consistent between rxvt, urxvt (under Cygwin XFree X Server), mintty and PuttyCyg. Is there a similar configuration file where output encoding can be set (i.e. the equivalent of setting output locale on a Linux system)?

• How can I display an ASP.NET MVC html part from one application in another

  - by Frank Sessions

  We have several asp.net MVC apps in the following setup SecurityApp (root application - handles forms auth for SSO and has a profile edit page) Application1 (virtual directory) Application2 (virtual directory) Application3 (virtual directory) so that domain.com points to SecurityApp and domain.com/Application1 etc point to their associated virtual directories. All of our Single Sign On (SSO) is working properly using forms authentication. Based on the users permissions when logging in a menu that lists their available applications and a logout link will be generated and saved in the cache - this menu displays fine whenever the user is in the SecurityApp (editing their profile) but we cannot figure out how to get the Applications in the virtual directories to display the same application menu. We have tried: 1) Using JSONP to do an request that will return the html for the menu. The ajax call returns the HTML with the html; however, because User.IsAuthenticated is false the menu comes back empty. 2) We created a user control and include it along with the dll's for the SecurityApp project and this works; however, we dont want to have to include all the dlls for the SecurityApp project in every application that we create (along with all the app settings in the web.config) We would like this to be as simple as possible to implement so that anyone creating a new app can add the menu to their application in as few steps as possible... Any ideas? To Clarify - we are using ASP.NET MVC 1.0 since these apps are in production and we do not have the okay to go to ASP.NET MVC 2.0 (unfortunately)

• C# How to commit a TextBox?

  - by Jake

  Hi, In a form, I have a TextBox Binding an Object on its member property "Title". Along with it is a "Save" button to test the binding. Seems like the underlying object property does not get updated unless the textbox loses focus. But there no form.ActiveControl.Blur() for use. Besides, this does not seem like a sound hack. Anyway to do this better? Thanks. EDIT: Sorry for not being clear. My question is in the title: "How to commit a TextBox". I use the term "commit" from the DataGridView commit and BindingSource commit. And it's in WinForms. (Have never worked with WPF, so it didn't occur to me. Sorry). The actual scenario I have is I have a bunch of TextBox binded to property of a single Object. The user enters values in all the TextBox and when the user clicks save (toolbar button), the last TextBox is still in focus (or in editing mode) hence the save will not capture the last value in the last textbox. I want to find the correct way to "commit" the textbox value just before saving. Thanks.

• XML Catalog in Eclipse is not working

  - by svaret

  Where I work we do not have any internet connection. We still want to have validation and code completion when editing xml files. I have tried the instructions here http://www.helmers.nu/?p=276 However, I try the instructions, restarts eclipse, do reload dependencies. I still cannot get any code completion nor validation. Can anyone point me in the right direction? I have tried both with Eclipse Galileo and Helios. My catalog.xml <?xml version="1.0" encoding="UTF-8" standalone="no"?> <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"> <uri name="http://www.liquibase.org/xml/ns/dbchangelog/1.9" uri="file:///C:/dev/XMLSchemaDefinition/dbchangelog-1.9.xsd"/> </catalog> My xml-file: <?xml version="1.0" encoding="UTF-8" standalone="no"?> <databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog/1.9" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog/1.9 http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-1.9.xsd"> </databaseChangeLog>

• Code golf: combining multiple sorted lists into a single sorted list

  - by Alabaster Codify

  Implement an algorithm to merge an arbitrary number of sorted lists into one sorted list. The aim is to create the smallest working programme, in whatever language you like. For example: input: ((1, 4, 7), (2, 5, 8), (3, 6, 9)) output: (1, 2, 3, 4, 5, 6, 7, 8, 9) input: ((1, 10), (), (2, 5, 6, 7)) output: (1, 2, 5, 6, 7, 10) Note: solutions which concatenate the input lists then use a language-provided sort function are not in-keeping with the spirit of golf, and will not be accepted: sorted(sum(lists,[])) # cheating: out of bounds! Apart from anything else, your algorithm should be (but doesn't have to be) a lot faster! Clearly state the language, any foibles and the character count. Only include meaningful characters in the count, but feel free to add whitespace to the code for artistic / readability purposes. To keep things tidy, suggest improvement in comments or by editing answers where appropriate, rather than creating a new answer for each "revision". EDIT: if I was submitting this question again, I would expand on the "no language provided sort" rule to be "don't concatenate all the lists then sort the result". Existing entries which do concatenate-then-sort are actually very interesting and compact, so I won't retro-actively introduce a rule they break, but feel free to work to the more restrictive spec in new submissions. Inspired by http://stackoverflow.com/questions/464342/combining-two-sorted-lists-in-python

• what libraries or platforms should I use to build web apps that provide real-time, asynchronous data

  - by Daniel Sterling

  This is a less a question with a simple, practical answer and more a question to foster discussion on the real-time data exchange topic. I'll begin with an example: Google Wave is, at its core, a real-time asynchronous data synchronization engine. Wave supports (or plans to support) concurrent (real-time) document collaboration, disconnected (offline) document editing, conflict resolution, document history and playback with attribution, and server federation. A core part of Wave is the Operational Transformation engine: http://www.waveprotocol.org/whitepapers/operational-transform The OT engine manages document state. Changes between clients are merged and each client has a sane and consistent view of the document at all times; the final document is eventually consistent between all connected clients. My question is: is this system abstract or general enough to be used as a library or generic framework upon which to build web apps that synchronize real-time, asynchronous state in each client? Is the Wave protocol directly used by any current web applications (besides Google's client)? Would it make sense to directly use it for generic state synchronization in a web app? What other existing libraries or frameworks would you consider using when building such a web app? How much code in such an app might be domain-specific logic vs generic state synchronization logic? Or, put another way, how leaky might the state synchronization abstractions be? Comments and discussion welcomed!

• Using bitwise operators on > 32 bit integers

  - by dqhendricks

  I am using bitwise operations in order to represent many access control flags within one integer. ADMIN_ACCESS = 1; EDIT_ACCOUNT_ACCESS = 2; EDIT_ORDER_ACCESS = 4; var myAccess = 3; // ie: ( ADMIN_ACCESS | EDIT_ACCOUNT_ACCESS ) if ( myAccess & EDIT_ACCOUNT_ACCESS ) { // check for correct access // allow for editing of account } Most of this is occurring on the PHP side of my project. There is one piece however where Javascript is used to join several access flags using | when saving someone's access level. This works fine to a point. I have found that once an integer (flag) gets too large ( 32bit), it no longer works correctly with bitwise operators in Javascript. For instance: alert( 4294967296 | 1 ); // equals 1, but should equal 4294967297 I am trying to find a workaround for this so that I do not have to limit my number of access control flags to 32. Each access control flag is two times the previous control flag so that each control flag will not interfere with other control flags. dec(4) = bin(100) dec(8) = bin(1000) dec(16) = bin(10000) I have noticed that when adding two of these flags together with a simple +, it seems to come out with the same answer as a bitwise or operation, but am having trouble wrapping my head around whether this is a simple substitution, or if there might be problems with doing this. Can anyone comment on the validity of this workaround? Example: (4294967296 | 262144 | 524288) == (4294967296 + 262144 + 524288)

• Convert Form to UserControl

  - by Joe

  I have a 3rd party code library that I'm using; part of this library is a winforms application for editing the configuration files used by this library. I would like to embed their configuration editor app into my application. I have the source code to their library and the configuration editor is (as far as I can tell) a straight forward Winforms app using standard controls. I'm trying to convert the app's main form into a UserControl so that I can host it inside my application which is WPF (WPF's WindowsFormsHost won't host a Form object, I get an exception). I changed the form object to inherit from UserControl instead of Form and fixed all the compiler errors (there weren't many, just property initializations that don't exist on UserControls) but what's happening is my newly converted control is just blank. When I run my test app I don't see any of the controls that make up the original form, just a blank page. Any ideas? I really don't want to have to re-implement their app from scratch, that would suck. Edit: I forgot to mention I'm testing this in a WinForms application, not WPF, to just get the control working before trying to use it from WPF.

• Replace textfields with dropdown select fields

  - by 47

  I have three model classes that look as below: class Model(models.Model): model = models.CharField(max_length=20, blank=False) manufacturer = models.ForeignKey(Manufacturer) date_added = models.DateField(default=datetime.today) def __unicode__(self): name = ''+str(self.manufacturer)+" "+str(self.model) return name class Series(models.Model): series = models.CharField(max_length=20, blank=True, null=True) model = models.ForeignKey(Model) date_added = models.DateField(default=datetime.today) def __unicode__(self): name = str(self.model)+" "+str(self.series) return name class Manufacturer(models.Model): MANUFACTURER_POPULARITY_CHOICES = ( ('1', 'Primary'), ('2', 'Secondary'), ('3', 'Tertiary'), ) manufacturer = models.CharField(max_length=15, blank=False) date_added = models.DateField(default=datetime.today) manufacturer_popularity = models.CharField(max_length=1, choices=MANUFACTURER_POPULARITY_CHOICES) def __unicode__(self): return self.manufacturer I want to have the fields for model series and manufacturer represented as dropdowns instead of text fields. I have customized the model forms as below: class SeriesForm(ModelForm): series = forms.ModelChoiceField(queryset=Series.objects.all()) class Meta: model = Series exclude = ('model', 'date_added',) class ModelForm(ModelForm): model = forms.ModelChoiceField(queryset=Model.objects.all()) class Meta: model = Model exclude = ('manufacturer', 'date_added',) class ManufacturerForm(ModelForm): manufacturer = forms.ModelChoiceField(queryset=Manufacturer.objects.all()) class Meta: model = Manufacturer exclude = ('date_added',) However, the dropdowns are populated with the unicode in the respective class...how can I further customize this to get the end result I want? Also, how can I populate the forms with the correct data for editing? Currently only SeriesForm is populated. The starting point of all this is from another class whose declaration is as below: class CommonVehicle(models.Model): year = models.ForeignKey(Year) series = models.ForeignKey(Series) .... def __unicode__(self): name = ''+str(self.year)+" "+str(self.series) return name

• Storing Arbitrary Contact Information in Ruby on Rails

  - by Anthony Chivetta

  Hi, I am currently working on a Ruby on Rails app which will function in some ways like a site-specific social networking site. As part of this, each user on the site will have a profile where they can fill in their contact information (phone numbers, addresses, email addresses, employer, etc.). A simple solution to modeling this would be to have a database column per piece of information I allow users to enter. However, this seems arbitrary and limited. Further, to support allowing users to enter as many phone numbers as they would like requires the addition of another database table and joins. It seems to me that a better solution would be to serialize all the contact information entered by a user into a single field in their row. Since I will never be conditioning a SQL query on this information, such a solution wouldn't be any less efficient. Ideally, I would like to use a vCard as my serialization format. vCards are the standard solution to storing contact information across the web, and reusing tested solutions is a Good Thing. Alternative serialization formats would include simply marshaling a ruby hash, or YAML. Regardless of serialization format, supporting the reading and updating of this information in a rails-like way seems to be a major implementation challenge. So, here's the question: Has anyone seen this approach used in a rails application? Are there any rails plugins or gems that make such a system easy to implement? Ideally what I would like is an acts_as_vcard to add to my model object that would handle editing the vcard for me and saving it back to the database.

• Control pdb file output from build defintion file

  - by Urvi

  Hello, I am trying to generate a release build with no pdb files generated. I have seen numerous posts that suggest right-clicking on the project, selecting Properties, going to the Build tab and then to the Advanced... butoon and changing Debug Info to none. This works and all, but I need to do this for a build of ~50 solutions which contain ~25 projects each! Other posts mention editing the appropriate .csproj file, but again, with so many projects, this would take a long time. Is there any way to achieve this via the TFSBuild.proj file? I have tried adding the following to the TFSBuild.proj file, with no luck. <PropertyGroup> <Configuration>Release</Configuration> <Platform>AnyCPU</Platform> </PropertyGroup> <PropertyGroup> <DebugSymbols>false</DebugSymbols> <DebugType>none</DebugType> <Optimize>true</Optimize> </PropertyGroup> The following line prints out Release|AnyCPU, none, and false, but I still see .pdb file in the $(OutputDir) folder. <Message Text="$Configuration|Platform): $(Configuration)|$(Platform)" /> <Message Text="DebugType is: $(DebugType)"/> <Message Text="DebugSymbols is: $(DebugSymbols)"/> Thanks in advance, Urvi

• Cannot edit values of DataGridView bound to a BindingList

  - by m_oLogin

  Hello community, I have trouble editing a databound bindinglist. Let me illustrate it with the following: Say I have the Person class: public Class Person{ private string m_firstname; private string m_lastname; public string FirstName{get;set;} public string LastName{get;set;} public Person{ ... } } I then have a containing class called Population: public class Population{ private BindingList<Person> m_lstPerson = new BindingList<Person>(); private string m_countryName; public BindingList<Person> ListPerson{get; set;} public string CountryName { get; set; } } I then have on one form a first datagridview with DataSource = m_lstPopulation (BindingList). The binding works like a charm when working with the Population objects. When I double click, it opens up a dialog form showing the object details. One tab in the details holds a datagridview bound to that population's ListPerson. The second datagridview displays fine. However, I cannot edit or add cells in this datagridview. None of the columns is set to read-only. In fact, both datagridview have just about the same parameters. What am I missing? It seems that a lock has been placed on the Population object so that its inner fields cannot be edited... Please advise. Thanks.

• Eclipse CDT setup for remote build

  - by Posco Grubb

  Is there a better way to setup Eclipse CDT for local editing and remote building? I am working on a C++ project that uses GNU make in Linux. The code is under CVS on a Linux server. When I'm in the lab, I use Eclipse CDT on a Linux-x64 PC. The project is built on a Linux-x86 PC. All the computers in the lab (including the CVS server) have NFS mounts. When I'm at home, I use Eclipse CDT on a Windows 7 PC. The Windows PC connects to the Linux CVS server via SSH tunnel. To edit source, I rsync the C++ project under the Linux Eclipse workspace back to my Windows Eclipse workspace. (I can also do a remote CVS checkout on the Windows PC.) To build from home, I use a custom build command that SSH's to the Linux-x86 PC, rsync's the C++ project from my Windows Eclipse workspace to my Linux Eclipse workspace, and then runs make on the Liunx-x86 PC, specifying the correct path for the Makefile. In order to go back and forth between lab and home without committing my changes to CVS every time, I use rsync. When I transition from lab to home, I rsync sources to my Windows Eclipse workspace. When I build from home, the sources get rsync'd back to the Linux Eclipse workspace. Is there a better, less wonky way to do this? (I'm NOT interested in remote debugging.)

• Display gridview in new window

  - by Ricardo Deano

  Hello all. Just a bit of advice needed really in terms of how I should handle my current scenario: I have a web page that searches for products/category information the results of which are at present displayed in a gridview on the same page. However, said gridview is a bit of a beast and as such, I would like to have a page that the user searches for, a button is pressed and the subsequent gridview is displayed in a new window. Ultimately, I would like the user to be able to make multiple searches so that new windows can have multiple gridviews containing different data sets. My current thinking is to create session variables that can be pulled through onto 'the gridview page'. Having said that, I'm not sure that would work if multiple searches are created? I am also thinking I might be able to create said 'gridview window' using javascript but my concern here is the potential loss of functionality of the gridview i.e. paging, sorting, editing, etc. Does anyone have any thoughts or theories on this? What would be "best practise"? Any thoughts greatly appreciated and taken on board. PS: This is being developed in .net, using c# and LINQ. PPS: I'm a noob so be gentle!!

• VS2010 express beta2 - no add reference dialog, no open file/project dialogs

  - by David

  Just installed VS2010 express for Windows Phone last night. Install went smoothly. It creates a project, compiles, and deploys the app to the emulator. Here's the problem: When I try to "Add Reference" through the Project menu, I do not get the Add Reference dialog box. Same thing if I right click References in the solution explorer and click Add Reference. That's not all. "File...Open" and "File...Open Project" also fail to throw up an open file dialog box. When attempting any of these actions, the IDE quickly loses and regains focus. Even pressing a keyboard shortcut (Ctrl+O) causes the IDE to quickly lose and regain focus, but no open file dialog box appears. This is what I have tried, not particularly in this order: 1. Turned off UAC 2. Monitored file and registry access using Process Monitor during a File...Open operation. File activity showed mostly "SUCCESS" with a few "FAST IO DISALLOWED" and a few "INVALID DEVICE REQUEST" results. Registry activity showed mostly "SUCCESS" with some "NAME NOT FOUND" and a few "BUFFER OVERFLOW" results. 3. Created a new, clean Windows account to run the IDE from 4. Forced a test project to add a reference to "System.Xml.Linq" by editing the ".csproj" project file. Project failed to load in the IDE. I don't have these problems at all on 2 other Windows 7 computers with VS2010 C# express beta 2 installed. One machine is 32bit and the other 64bit, both Home Premium edition. My system: Windows 7 Home Premium, 64bit Other Visual Studio products installed: VS2008 C# express, VS2008 C++ express One other thing to note: Several months ago I installed the non-phone distribution of VS2010 C# express beta 2, and I had the same exact problems. Back then I chalked it up to being beta and went back to VS2008 C# express, where I do not have these issues.

• Best way to databind a Winforms control to a nullable type?

  - by Steve Hiner

  I'm currently using winforms databinding to wire up a data editing form. I'm using the netTiers framework through CodeSmith to generate my data objects. For database fields that allow nulls it creates nullable types. I've found that using winforms databinding the controls won't bind properly to nullable types. I've seen solutions online suggesting that people create new textbox classes that can handle the nullable types but that could be a pain having to swap out the textboxes on the forms I've already created. Initially I thought it would be great to use an extension method to do it. Basically creating an extension property for the textbox class and bind to that. From my limited extension method experience and doing a bit of checking online it looks like you can't do an extension property. As far as I can tell, binding has to be through a property since it needs to be able to get or set the value so an extension method wouldn't work. I'd love to find a clean way to retrofit these forms using something like extension methods but if I have to create new textbox and combo box controls that's what I'll do. My project is currently limited to .Net 2.0 due to the requirement to run on Windows 2000. Any suggestions?

• List of models in Model in MVC

  - by arri

  I have two models: class ModelIn{ public string FirstName { get; set; } public string LastName { get; set; } public string Address { get; set; } } class ModelOut{ public ModelOut(){ People = new List<ModelIn>();} public List<ModelIn> People { get; private set;} public string Country { get; set; } } And I have Controller editing ModelOut: public ActionResult People() { ... return View(SomeModelOutInstanceWith3People); } [HttpPost] public ActionResult(ModelOut m) { ... } In view I have sth like: <% using (Html.BeginForm()) { %> <%: Html.EditorFor(m => Model.Country) %> <% for(int i = 0; i < Model.People.Count; ++i){ %> <%: Html.EditorFor(m => Model.People[i].FirstName) %> <%: Html.EditorFor(m => Model.People[i].LastName) %> <%: Html.EditorFor(m => Model.People[i].Address) %> <% } %> <input type="submit" /> <% } %> It works all OK, but in post action I have empty ModelOut m. I can see in logs that data is sent correctly. I have tried everything, nothing works.

• Viewing namespaced global variables in Visual Studio debugger?

  - by Chris

  When debugging a non-managed C++ project in Visual Studio 2008, I occasionally want to see the value of a global variable. We don't have a lot of these but those that are there all declared within a namespace called 'global'. e.g. namespace global { int foo; bool bar; ... } The problem is that when the code is stopped at a breakpoint, the default debugging tooltip (from pointing at the variable name) and quickwatch (shift-f9 on the variable name) don't take the namespace into consideration and hence won't work. So for example I can point at 'foo' and nothing comes up. If I shift-f9 on foo, it will bring up the quickwatch, which then says 'CXX0017: Error: symbol "foo" not found'. I can get around that by manually editing the variable name in the quickwatch window to prefix it with "global::" (which is cumbersome considering you have to do it each time you want to quickwatch), but there is no fix for the tooltip that I can work out. Setting the 'default namespace' of the project properties doesn't help. How can I tell the VS debugger to use the namespace that it already knows the variable is declared in (since it has the declaration right there), or, alternatively, tell it a default namespace to look for variables in if it doesn't find them? My google-fu has failed to find an answer. This report lists the same problem, with MS saying it's "by design", but even so I am hoping there is some way to work around it (perhaps with clever use of autoexp.dat?)

• Entity Framework. Updating EntityCollection using disconnected objects via navigation property.

  - by yougotiger

  I have a question, much liket this unanswered one. I'm trying to work with the entity framework, and having a tough time getting my foreign tables to update. I have something basically like this in the DB: Incident (table): -ID -other fields Responses (table): -FK:Incident.ID -other fields And and entities that match: Incident (entity) -ID -Other fields -Responses (EntityCollection of Responses via navigation property) Each Incident can have 0 or more responses. In my Webpage, I have a form to allow the user to enter all the details of an Incident, including a list of responses. I can add everything to the database when a new Incident is created, however I'm having difficulty with editing the Incident. When the page loads for edit, I populate the form and then store the responses in the viewstate. When the user changes the list of responses (adds one, deletes one or edits one). I store this back into the viewstate. Then when the user clicks the save button, I'd like to save the changes to the Incident and the Responses back to the DB. I cannot figure out how to get the responses from the detached viewstate into the Incident object so that they can be updated together. Currently when the user clicks save, I'm getting the Incident to edit from the db, making changes to the Incident's fields and then saving it back to the DB. However I can't figure out how to have the detached list of responses from the viewstate attach to the Incident. I have tried the following without success: Clearning the Incident.Responses collection and adding the ones from the viewstate back in: Incident.Responses.Clear() for each objResponse in Viewstate("Responses") Incident.Responses.add(objResponse) next Creating an EntityCollection from my list and then assiging that to the Incident.Responses Incident.Responses = EntityCollectionFromViewstateList Iterating through the responses in Incident.Response and assigning the corresponding object from viewstate: for each ObjResponse in Incident.Responses objResponse = objCorrespondingModifedResonseFromViewState Next These all fail, I'd like to be able to merge the changes into the Inicdent object so that when the BLL calls SaveChanges on the changes to both the Incident and Responses will happen at the same time. Any suggestions? I keep finding lots of stuff about assigning foreign keys (singular), but I haven't found a great solution for doing a set of entities assigned to another entity in this manner.
