  • WPF UserControl weird binding problem

    - by Heko
    Hello! Im usign a Ribbon Window and in the "content area beneath" I have a grid in which I will be displaying UserControls. To demonstrate my problem lets take a look at this simple UserControl: <ListView x:Name="lvPersonList"> <ListView.View> <GridView> <GridViewColumn Width="120" Header="Name" DisplayMemberBinding="{Binding Name}"/> <GridViewColumn Width="120" Header="Height" DisplayMemberBinding="{Binding Height}"/> </GridView> </ListView.View> </ListView> And the code: public partial class MyUserControl: UserControl { private List<Person> personList; public TestSnpList() { InitializeComponent(); this.personList = new List<Person>(); this.personList.Add(new Person { Name = "Chuck Norris", Height = 210 }); this.personList.Add(new Person { Name = "John Rambo", Height = 200 }); this.lvPersonList.ItemsSource = personList; } } public class Person { public string Name { get; set; } public int Height { get; set; } } The parent Window: <Grid x:Name="grdContent" DockPanel.Dock="Top"> <controls:MyUserControl x:Name="myUserControl" Visibility="Visible"/> </Grid> I don't understant why this binding doesn't work. Instead of values (Name and Height) I get full class names. If I use this code in a Window it works fine. Any ideas? I would like this user contorl works for itself (it gets the data form the DB and represents it in a ListView)... Thanks!

  • Updating textfield in doctrine produces an exception

    - by james-murphy
    I have a textfield that contains say for example the following text:- "A traditional English dish comprising sausages in Yorkshire pudding batter, usually served with vegetables and gravy." This textfield is in a form that simply updates an item record using it's ID. If I edit part of the textfield and replace "and gravy." with "humous." So that the textfield now contains "A traditional English dish comprising sausages in Yorkshire pudding batter, usually served with vegetables and humous." I get the following exception:- Fatal error: Uncaught exception 'Doctrine_Query_Exception' with message 'Unknown component alias humous' in C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php:780 Stack trace: C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php(767): Doctrine_Query_Abstract-getQueryComponent('humous') C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Set.php(58): Doctrine_Query_Abstract-getAliasDeclaration('humous') C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php(2092): Doctrine_Query_Set-parse('i.details = 'A ...') C:\Projects\nitrous\lightweight\system\database\Doctrine\Query.php(1058): Doctrine_Query_Abstract-_processDqlQueryPart('set', Array) C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php(971): Doctrine_Query-getSqlQuery(Array) C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php(1030): Doctrine_Query_Abstract-_execute(Array) C:\Projects\nitrous\lightweight\system\appl in C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php on line 780 I'm using Doctrine 1.0.6 hooked into CodeIgniter 1.7.0 if anyone is interested. My doctrine query that actually performs the update looks as follows:- public function updateItems($id, $arrayItem) { $query = new Doctrine_Query(); $query->update('Item i'); foreach($arrayItem as $key => $value) { $query->set('i.'.$key, "'".$value."'"); } $query->where('i.id = ?', $id); return $query->execute(); } This seems bizarre because if i replace the entire string "A traditional English dish comprising sausages in Yorkshire pudding batter, usually served with vegetables and humous." with something completely different like just "test" it doesn't throw an exception and works just fine. This baffles me... is it a bug in Doctrine or have I missed something?

  • Display HTML page in Office 2003 or 2007 task pane via VBA

    - by Malcolm
    Is it possible to display an HTML page in an Office 2003 and/or 2007 task pane via VBA? Background: We have a complicated configuration file that our users maintain in Word (using a real editor is not an option for our audience). We would like to create several toolbar buttons that display a basic HTML page in a task pane as a form of online help for our users. The reason we want to use a task pane to display help (vs. an external browser or traditional help engine) is so that the help content is "embedded" in Word vs. displayed via a seperate application. The problem with using a regular browser or help engine to display help is that users have to manually size and position both applications so that they can see them simultaneously and its very easy to "lose" one application when togging between many applications. We don't want to go down the route of writing a VisualStudio based task pane component - we want to keep things simple (KISS) and encapsulate everything in an easy to distribute Word template file (.dot or dotx.). Suggestions?

  • Double buffering with C# has negative effect

    - by Roland Illig
    I have written the following simple program, which draws lines on the screen every 100 milliseconds (triggered by timer1). I noticed that the drawing flickers a bit (that is, the window is not always completely blue, but some gray shines through). So my idea was to use double-buffering. But when I did that, it made things even worse. Now the screen was almost always gray, and only occasionally did the blue color come through (demonstrated by timer2, switching the DoubleBuffered property every 2000 milliseconds). What could be an explanation for this? using System; using System.Drawing; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Paint(object sender, PaintEventArgs e) { Graphics g = CreateGraphics(); Pen pen = new Pen(Color.Blue, 1.0f); Random rnd = new Random(); for (int i = 0; i < Height; i++) g.DrawLine(pen, 0, i, Width, i); } // every 100 ms private void timer1_Tick(object sender, EventArgs e) { Invalidate(); } // every 2000 ms private void timer2_Tick(object sender, EventArgs e) { DoubleBuffered = !DoubleBuffered; this.Text = DoubleBuffered ? "yes" : "no"; } } }

  • Zend Framework subdomain+subfolder router rewrite problem

    - by zf_novice
    I'm new to Zend Framwork and this is an issue I've been struggling for several hours already... I'm trying to chain Hostname and standard Route in order to get url with subdomain+subfolders ie.: http:// lang.mydomain.com/myapplication/public/controller http:// lang.mydomain.com/myapplication/public/controller/action (sorry for the empty space in the address, this site won't allow links) Basically what I have done in Bootstrap is: // add language to default route $routePath = new Zend_Controller_Router_Route( ':controller/:action/*', array('controller'=>'index','action' => 'index','module'=>'default') ); $routeHostname = new Zend_Controller_Router_Route_Hostname( ':lang.mydomain.com', array('lang'=>$lang) ); $frontController = $this->getResource('FrontController'); $router = $frontController->getRouter(); $router->addRoute('default', $routeHostname->chain($routePath)) $frontController->setRouter($router); it finds the route ok, but every time I generate url in view or layout by $this-url() <?php echo $this->url( array( 'controller'=> 'guestbook', 'action' => 'sign', 'lang' => Zend_Registry::get('lang'), ), 'default', true) ?>"> I get http:// lang.mydomain.com/controller instead of http:// lang.mydomain.com/myapplication/public/controller I've been trying to set baseUrl on front controller but no luck... Also I've tried the static route with myapplication/public or following standard route: 'myapplication/public/:controller/:action/*' - it result with "An error occurred Page not found Exception information: Message: No route matched the request" and empty request Is there any way to assembly subdomain with subfolder in Zend Framwork?? EDIT: I changed above to: $frontController->setBaseUrl('.'); // add language to default route $routePath = new Zend_Controller_Router_Route( 'quickstart/public/:controller/:action/*', array( 'controller'=>'index', 'action' => 'index', 'module'=>'default', ) ); and it works form me, although I'm not sure whether it's been correct approach...

  • Is there a way to receive receive data as unsugned char over UDP on QT

    - by user269037
    I need to send floating point numbers using UDP connection to a QT application. Now in QT the only function available is qint64 readDatagram ( char * data, qint64 maxSize, QHostAddress * address = 0, quint16 * port = 0 ) which accepts data in the form of signed character buffer. I can convert my float into a string and send it but it will obviously not be very efficient converting a 4 byte float into a much longer sized character buffer. I got hold of these 2 functions to convert a 4 byte float into an unsinged 32 bit integer to transfer over network which works fine for a simple c++ udp program but for QT I need to receive the data as unsigned char. Is it possible to avoid converting the floatinf point data into a string and then sending it ?? uint32_t htonf(float f) { uint32_t p; uint32_t sign; if (f < 0) { sign = 1; f = -f; } else { sign = 0; } p = ((((uint32_t)f)&0x7fff)<<16) | (sign<<31); // whole part and sign p |= (uint32_t)(((f - (int)f) * 65536.0f))&0xffff; // fraction return p; } float ntohf(uint32_t p) { float f = ((p16)&0x7fff); // whole part f += (p&0xffff) / 65536.0f; // fraction if (((p>>31)&0x1) == 0x1) { f = -f; } // sign bit set return f; }

  • .NET C# : Image Conversion from Bitmap to Icon doesn't seem to work

    - by contactmatt
    I have a simple function that takes a bitmap, and converts the bitmap to an ICON format. Below is the function. (I placed literal values in place of the variables) Bitmap tempBmp = new Bitmap(@"C:\temp\mypicture.jpeg"); Bitmap bmp = new Bitmap(tempBmp, 16, 16); bmp.Save("@C:\temp\mypicture2.ico", ImageFormat.Icon) It doesn't seem to be converting correctly...or so I think. After the image is converted, some browsers do not reconigze the image as a true "ICON" , and even Visual Studio 2008 doesn't reconigze the image as an icon after its converted to an Icon format. For example, I was going to set the Icon property for my Win32 form app with the Icon i just converted. I open the dialouge box and select the icon I just converted and get the following error. -- "Argument 'picture' must be a picture that can be used as a Icon." I've browsed the web and come across complicated code where people take the time to manually convert the bitmap to different formats, but I would think the above code should work, and that the .NET framework would take care of this conversion.

  • More efficient way to find media item in WMP media library?

    - by RoseOfJericho
    Hello, all. I am messing around with the WMPLib component provided by Windows Media Player 12 (wmp.dll) in VB.NET with .NET Framework 3.5 SP1. I am trying to retrieve a media item from my media library based on its name (assuming there are no duplicate names). At the moment, I'm grabbing the entire media library, and looping through every media item, and quitting the loop when I've found the correct media item. This works well (except for when a media item with that name cannot be found), but I was hoping there was a more efficient way of doing this. Here is my code so far: Public Class WMPTest Private myWMP As WMPLib.IWMPCore Private myMediaCollection As WMPLib.IWMPMediaCollection Private myTrack As WMPLib.IWMPMedia Private allTracks As WMPLib.IWMPPlaylist Public Sub New() ' This call is required by the Windows Form Designer. InitializeComponent() ' Add any initialization after the InitializeComponent() call. myWMP = New WMPLib.WindowsMediaPlayer myMediaCollection = myWMP.mediaCollection allTracks = myMediaCollection.getAll Dim theTrack As WMPLib.IWMPMedia = findTrack("Yellow Submarine") MessageBox.Show(theTrack.name) End Sub Public Function findTrack(ByVal strTrackName As String) As WMPLib.IWMPMedia For i As Integer = 0 To (allTracks.count - 1) If allTracks.Item(i).name = strTrackName Then myTrack = allTracks.Item(i) Exit For End If Next 'myTrack is now the track that we wanted to retrieve Return myTrack End Function End Class So what I really want is a way to optimize findTrack() to do its thing without looping through the entire media library (which could be huge). Anyone have a clue?

  • Application Errors vs User Errors in PHP

    - by CogitoErgoSum
    So after much debate back and forth, I've come up with what I think may be a valid plan to handle Application/System errors vs User Errors (I.e. Validation Issues, Permission Issues etc). Application/System Errors will be handled using a custom error handler (via set_error_handler()). Depending on the severity of the error, the user may be redirected to a generic error page (I.e. Fatal Error), or the error may simply be silently logged (i.e E_WARNING). These errors are ones most likely caused by issues outside the users control (Missing file, Bad logic, etc). The second set of errors would be User Generated ones. These are the ones may not automatically trigger an error but would be considered one. In these cases i"ve decided to use the trigger_error() function and typically throw a waning or notice which would be logged silently by the error handler. After that it would be up to the developer to then redirect the user to another page or display some sort of more meaningful message to the user. This way an error of any type is always logged, but user errors still allow the developer freedom to handle it in their own ways. I.e. Redirect them back to their form with it fully repopulated and a message of what went wrong. Does anyone see anything wrong with this, or have a more intuitive way? My approach to error handling is typically everyone has their own ways but there must be a way instituted.

  • Why is Dispatcher.Invoke not triggering UI update?

    - by Brandon
    I am trying to reuse a UserControl and also borrow some logic that keeps track of progress. I'll try and simplify things. MyWindow.xaml includes a MyUserControl. MyUserControl has its own progress indicator (Formatting in progress..., Copying files..., etc.) and I'd like to mirror this progress somewhere in the MyWindow form. But, the user control has some logic I don't quite understand. I've read and read but I still don't understand the Dispatcher. Here's a summary of the logic in the user control that updates the progress. this.Dispatcher.Invoke(DispatcherPriority.Input, (Action)(() => { DAProgressIndicator = InfiniteProgress.AddNewInstanceToControl(StatusGrid, new SolidColorBrush(new Color() { A = 170, R = 128, G = 128, B = 128 }), string.Empty); DAProgressIndicator.Message = MediaCardAdminRes.ActivatingCard; ActivateInProgress = true; })); I thought I'd be smart and add an event to MyUserControl that would be called in the ActivateInProgress property set logic. public bool ActivateInProgress { get { return _activateInProgress; } set { _activateInProgress = value; if (ActivateInProgressHandler != null) { ActivateInProgressHandler(value); } } } I'm setting the ActivateInProgressHandler within the MyWindow constructor to the following method that sets the view model property that is used for the window's own progress indicator. private void SetActivation(bool activateInProgress) { viewModel.ActivationInProgress = activateInProgress; } However, the window's progress indicator never changes. So, I'm convinced that the Dispatcher.Invoke is doing something that I don't understand. If I put a message box inside the SetActivation method, the thread blocks and the window's progress indicator is updated. I understand basic threads but this whole Dispatcher thing is new to me. What am I missing?

  • jQuery / jEditable and jQuery UI Dialog. Re-populating table cell.

    - by solefald
    Hello, this is my first time using JS, so i really have no idea what i am doing. I have a table with data, and using jEditable to allow a user to edit the data and POST it to my php script. When user hits "Save", it opens jQuery UI with the data from php script and it seems to work fine, however, if the user hits Cancel or Esc to close the jQuery UI dialog, they and up back on the page, but the cell they tried to edit is now completely empty. How do i get the cell re-populated? Thank you! $(".editable_textarea").editable("/path/to/my/scrip.php", { indicator : "<img src='/images/indicator.gif'>", type : 'textarea', submitdata: { _method: "post", uri: "<?php echo $this->uri->segment(3); ?>" }, select : false, submit : 'Save', cancel : 'Cancel', tooltip : "Click to edit...", cssclass : "editable", onblur: "cancel", cssclass: "edit_destination", callback: function(value, settings) { $(this).dialog({ autoOpen: true, width: 400, modal: true, position: "center", resizable: false, draggable: false, title: "Pending Changes", buttons: { "Cancel": function() { $(this).dialog("close"); }, "Confirm Changes": function() { document.findSameDestination.submit(); } } }); $('form#findSameDestination').submit(function(){ $(this).dialog('open'); return false; }); $(this).editable("disable"); }, data: function(value, settings) { var retval = value.replace(/<br[\s\/]?>/gi, '\n'); retval = retval.replace(/(<([^>]+)>)/gi, ''); return retval; } });

  • Good DB Migrations for CakePHP?

    - by Martin Westin
    Hi, I have been trying a few migration scripts for CakePHP but I ran into problems with all of the in some form or another. Please advice me on a migration option for Cake that you use live and know works. I'd like the following "features": -Support CakePHP 1.2(e.g. CakeDCs migrations will only be an option when 1.3 is stable and my app migrated to the new codebase) -Support for (or at least not halt on) Models with a different database config. -Support Models in sub-folders of app/models -Support Models in plugins -Support tables that do not conform to Cake conventions (I have a few special tables that do not have a single primary key field and need to keep them) -Plays well with automated deployment via Capistrano and Git. I do not need rails-style versioned files a git versioned schema file that is compared live to the existing schema will do. That is: I like the SchemaShell in Cake apart from it not being compatible with most of my requirements above. I have looked at and tested: CakePHP Schema Shell http://book.cakephp.org/view/734/Schema-management-and-migrations CakeDC migrations http://cakedc.com/downloads/view/cakephp_migrations_plugin YAML migrations http://github.com/georgious/cakephp-yaml-migrations-and-fixtures joelmoss migrations http://code.google.com/p/cakephp-migrations

  • jQuery addClass on $.post

    - by Tim
    I am basically trying to create a small registration form. If the username is already taken, I want to add the 'red' class, if not then 'green'. The PHP here works fine, and returns either a "YES" or "NO" to determine whether it's ok. The CSS: input { border:1px solid #ccc; } .red { border:1px solid #c00; } .green { border:1px solid green; background:#afdfaf; } The Javascript I'm using is: $("#username").change(function() { var value = $("#username").val(); if(value!= '') { $.post("check.php", { value: value }, function(data){ $("#test").html(data); if(data=='YES') { $("#username").removeClass('red').addClass('green'); } if(data=='NO') { $("#username").removeClass('green').addClass('red'); } }); } }); I've got the document.ready stuff too... It all works fine because the #test div html changes to either "YES" or "NO", apart from the last part where I check what the value of the data is. Here is the php: $value=$_POST['value']; if ($value!="") { $sql="select * FROM users WHERE username='".$value."'"; $query = mysql_query($sql) or die ("Could not match data because ".mysql_error()); $num_rows = mysql_num_rows($query); if ($num_rows 0) { echo "NO"; } else { echo "YES"; } }

  • Perl unpack in list context

    - by drewk
    A common 'Perlism' is generating a list as something to loop over in this form: for($str=~/./g) { print "the next character from \"$str\"=$_\n"; } In this case the global match regex returns a list that is one character in turn from the string $str, and assigns that value to $_ Instead of a regex, split can be used in the same way or 'a'..'z', map, etc. I am investigating unpack to generate a field by field interpretation of a string. I have always found unpack to be less straightforward to the way my brain works, and I have never really dug that deeply into it. As a simple case, I want to generate a list that is one character in each element from a string using unpack (yes -- I know I can do it with split(//,$str) and /./g but I really want to see if unpack can be used this way...) Obviously, I can use a field list for unpack that is unpack("A1" x length($str), $str) but is there some other way that kinda looks like globbing? ie, can I call unpack(some_format,$str) either in list context or in a loop such that unpack will return the next group of character in the format group until $str is exausted? I have read The Perl 5.12 Pack pod and the Perl 5.12 pack tutorial and the Perkmonks tutorial Here is the sample code: #!/usr/bin/perl use warnings; use strict; my $str=join('',('a'..'z', 'A'..'Z')); #the alphabet... $str=~s/(.{1,3})/$1 /g; #...in groups of three print "str=$str\n\n"; for ($str=~/./g) { print "regex: = $_\n"; } for(split(//,$str)) { print "split: \$_=$_\n"; } for(unpack("A1" x length($str), $str)) { print "unpack: \$_=$_\n"; }

    I am putting together the admin for a satchmo application. Satchmo uses OneToOne relations to extend the base Product model, and I'd like to edit it all on one page. It is possible to have a OneToOne relation as an Inline? If not, what is the best way to add a few fields to a given page of my admin that will eventually be saved into the OneToOne relation? for example: class Product(models.Model): name = models.CharField(max_length=100) ... class MyProduct(models.Model): product = models.OneToOne(Product) ... I tried this for my admin but it does not work, and seems to expect a Foreign Key: class ProductInline(admin.StackedInline): model = Product fields = ('name',) class MyProductAdmin(admin.ModelAdmin): inlines = (AlbumProductInline,) admin.site.register(MyProduct, MyProductAdmin) Which throws this error: <class 'satchmo.product.models.Product'> has no ForeignKey to <class 'my_app.models.MyProduct'> Is the only way to do this a Custom Form? edit: Just tried the following code to add the fields directly... also does not work: class AlbumAdmin(admin.ModelAdmin): fields = ('product__name',)

  • C# to find JobId, Owner, TotalPages from Printer

    - by tanthiamhuat
    My below code works when the Form loads and I can get a list of Network Printers in listBox1. I am also able to see a specific printer's property name and value in listBox2. private void Form1_Load(object sender, EventArgs e) { foreach (String printer in PrinterSettings.InstalledPrinters) { listBox1.Items.Add(printer.ToString()); } } private void button1_Click(object sender, EventArgs e) { string printerName = "Ricoh-L4-1"; string query = string.Format("SELECT * from Win32_Printer WHERE Name LIKE '%{0}'", printerName); ManagementObjectSearcher searcher = new ManagementObjectSearcher(query); ManagementObjectCollection coll = searcher.Get(); foreach (ManagementObject printer in coll) { foreach (PropertyData property in printer.Properties) { listBox2.Items.Add(string.Format("{0}: {1}", property.Name, property.Value)); } } } But when I try to find JobId, Owner, TotalPages for a particular printer (when I actually send jobs to print to that printer), those values do not display at all. private void button2_Click(object sender, EventArgs e) { listBox2.Items.Clear(); string printerName = "Ricoh-L4-1"; string query = string.Format("SELECT * from Win32_PrintJob WHERE Name LIKE '%{0}'", printerName); ManagementObjectSearcher SearchPrintJobs = new ManagementObjectSearcher(query); ManagementObjectCollection PrntJobCollection = SearchPrintJobs.Get(); foreach (ManagementObject PrntJob in PrntJobCollection) { string m_JobID = PrntJob.Properties["JobId"].Value.ToString(); string m_Owner = PrntJob.Properties["Owner"].Value.ToString(); string m_TotalPages = PrntJob.Properties["TotalPages"].Value.ToString(); listBox2.Items.Add(string.Format("{0}:{1}:{2}", m_JobID,m_Owner,m_TotalPages)); } } Do you have any idea how to get above to work? thanks in advance.

  • Accessing an enum stored in a QVariant

    - by Henry Thacker
    Hi, I have registered an enumeration type "ClefType" within my header file - this enum is registered with the MetaObject system using the Q_DECLARE_METATYPE and Q_ENUMS macros. qRegisterMetaType is also called in the class constructor. This allows me to use this type in a Q_PROPERTY, this all works fine. However, later on, I need to be able to get hold of the Q_PROPERTY of this enum type, given the object - in a form that is suitable for serialization. Ideally, it would be useful to store the integer value for that enum member, because I don't want this to be specific to the type of enum that is used - eventually I want to have several different enums. // This is inside a loop over all the properties on a given object QMetaProperty property = metaObject->property(propertyId); QString propertyName = propertyMeta.name(); QVariant variantValue = propertyMeta.read(serializeObject); // If, internally, this QVariant is of type 'ClefType', // how do I pull out the integer value for this enum? Unfortunately variantValue.toInt(); does not work - custom enums don't seem to be directly 'castable' to an integer value. Thanks in advance, Henry

  • VB.Net Custom Controls

    - by Paul
    This might be basic question, however I am confused on some .Net Concpets. I am trying to create a "Data Browser" in VB.net. Similar to a Web Browser however each Tab in the Data Browser is a view of some Data (from a database or flat files) not a webpage. The UI on each Tab is mostly the same. A list Box (showing datatypes, etc), a TextBox (where you can create a filter), and a DataGridView, a DataSource Picker, etc. The only thing that would change on each tab is that there could be a custom "Viewer". In most cases (depending on the datasource), this would be the datagrid, however in other cases it would be a treecontrol. From reading through the .Net documents, it appears that I need to Create a Custom Control (MyDataBrowser) Consisting of a Panel with all the common Controls (except the viewer). Every time the user says "New Tab", a new tabpage is created and this MyDataBrowser Control is added, The MyDataBrowser control would contain some function that was able to then create the approriate viewer based on the data at hand. If this is the suggested route, how is the best way to go about creating the MyDataBrowser Control (A) Is this a Custom Control Library? (B) Is this an Inhertited Form? (C) Is this an Inherrited User Control? I assume that I have to create a .DLL and add as a reference. Any direction on this would be appreciated. Does the custom Control have its own properties (I would like to save/load these from a configuration file). Is it possible to add a backgroundworker to this customcontrol? Thanks.

  • How to secure Add child record functionality in MVC on Parent's view?

    - by RSolberg
    I'm trying to avoid some potential security issues as I expose some a new set of functionality into the real world. This is basically functionality that will allow for a new comment to be added via a partialview on the "Parent" page. My comment needs to know a couple of things, first what record is the comment for and secondly who is making the comment. I really don't like using a hidden field to store the ID for the Parent record in the add comment form as that can be easily changed with some DOM mods. How should I handle this? PARENT <% Html.RenderPartial("AddComment", Model.Comments); %> CHILD <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<CommentsViewModel>" %> <% using (Html.BeginForm("AddComment", "Requests")) {%> <fieldset> <legend>New Comment</legend> <%= Html.HiddenFor(p => p.RequestID) %> <%= Html.TextBoxFor(p => p.Text) %> &nbsp; <input type="submit" value="Add" /> </fieldset> <% } %> CONTROLLER [AcceptVerbs(HttpVerbs.Post)] public void AddComment(CommentsViewModel commentsModel) { var user = GetCurrentUser(); commentsModel.CreatedByID = user.UserID; RequestsService.AddComment(commentsModel); }

  • ASP.NET MVC: what mechanic returns ViewModel objects?

    - by Dr. Zim
    As I understand it, Domain Models are classes that only describe the data (aggregate roots). They are POCOs and do not reference outside libraries (nothing special). View models on the other hand are classes that contain domain model objects as well as all the interface specific objects like SelectList. A ViewModel includes using System.Web.Mvc;. A repository pulls data out of a database and feeds them to us through domain model objects. What mechanic or device creates the view model objects, populating them from a database? Would it be a factory that has database access? Would you bleed the view specific classes like System.Web.Mvc in to the Repository? Something else? For example, if you have a drop down list of cities, you would reference a SelectList object in the root of your View Model object, right next to your DomainModel reference: public class CustomerForm { public CustomerAddress address {get;set;} public SelectList cities {get;set;} } The cities should come from a database and be in the form of a select list object. The hope is that you don't create a special Repository method to extract out just the distinct cities, then create a redundant second SelectList object only so you have the right data types.

  • GMap.NET shows no map

    - by Mariusz
    I'm trying to use the GMap.NET.WindowsForms control in my Windows forms application but I cannot make it show me any map. Here is what I did: I added the control to my Visual Studio's 2010 toolbox by clicking 'Choose Items...' from the toolbox's context menu and browsing for the GMap.NET.WindowsForms.dll included in the downloaded zip archive. I also added references to GMap.NET.Core.dll and System.Data.SQLite.dll in my solution. Then I put the GMapControl that appeared in the toolbox on the main form of my application and set the map type to GoogleMap. When I run my application, however, the control shows either a blue screen with a piece of text saying "We are sorry, but we don't have imagery at this zoom level for this region" or a bright screen with completely no data (when I change zoom level). Here is my code: GMapMain.MapType = MapType.GoogleMap; GMapMain.MaxZoom = 100; GMapMain.MinZoom = 0; GMapMain.Zoom = 50; GMapMain.CurrentPosition = new PointLatLng(54.6961334816182, 25.2985095977783); GMapMain.ReloadMap(); Please help. I have no idea what to do and I cannot find any information in the Internet that could help me solve the problem. Thank you very much in advance.
