  • ListCtrl - wxPython / Python

    - by Francisco Aleixo
    Hello everyone. My question is if we can assign/bind some value to a certain item and hide that value(or if we can do the same thing in another way). Example: Lets say the columns on ListCtrl are "Name" and "Description": self.lc = wx.ListCtrl(self, -1, style=wx.LC_REPORT) self.lc.InsertColumn(0, 'Name') self.lc.InsertColumn(1, 'Description') And when I add a item I want them to show the Name parameter and the description: num_items = self.lc.GetItemCount() self.lc.InsertStringItem(num_items, "Randomname") self.lc.SetStringItem(num_items, 1, "Some description here") Now what I want to do is basically assign something to that item that is not shown so I can access later on the app. So I would like to add something that is not shown on the app but is on the item value like: hiddendescription = "Somerandomthing" Still didn't undestand? Well lets say I add a button to add a item with some other TextCtrls to set the parameters and the TextCtrls parameters are: "Name" "Description" "Hiddendescription" So then the user fills this textctrls out and clicks the button to create the item, and I basically want only to show the Name and Description and hide the "HiddenDescription" but to do it so I can use it later. Sorry for explaining more than 1 time on this post but I want to make sure you understand what I pretend to do.

  • MSTest/NUnit Writing BDD style "Given, When, Then" tests

    - by Charlie
    I have been using MSpec to write my unit tests and really prefer the BDD style, I think it's a lot more readable. I'm now using Silverlight which MSpec doesn't support so I'm having to use MSTest but would still like to maintain a BDD style so am trying to work out a way to do this. Just to explain what I'm trying to acheive, here's how I'd write an MSpec test [Subject(typeof(Calculator))] public class when_I_add_two_numbers : with_calculator { Establish context = () => this.Calculator = new Calculator(); Because I_add_2_and_4 = () => this.Calculator.Add(2).Add(4); It should_display_6 = () => this.Calculator.Result.ShouldEqual(6); } public class with_calculator { protected static Calculator; } So with MSTest I would try to write the test like this (although you can see it won't work because I've put in 2 TestInitialize attributes, but you get what I'm trying to do..) [TestClass] public class when_I_add_two_numbers : with_calculator { [TestInitialize] public void GivenIHaveACalculator() { this.Calculator = new Calculator(); } [TestInitialize] public void WhenIAdd2And4() { this.Calculator.Add(2).Add(4); } [TestMethod] public void ThenItShouldDisplay6() { this.Calculator.Result.ShouldEqual(6); } } public class with_calculator { protected Calculator Calculator {get;set;} } Can anyone come up with some more elegant suggestions to write tests in this way with MSTest? Thanks

  • Setting up relations/mappings for a SQLAlchemy many-to-many database

    - by Brent Ramerth
    I'm new to SQLAlchemy and relational databases, and I'm trying to set up a model for an annotated lexicon. I want to support an arbitrary number of key-value annotations for the words which can be added or removed at runtime. Since there will be a lot of repetition in the names of the keys, I don't want to use this solution directly, although the code is similar. My design has word objects and property objects. The words and properties are stored in separate tables with a property_values table that links the two. Here's the code: from sqlalchemy import Column, Integer, String, Table, create_engine from sqlalchemy import MetaData, ForeignKey from sqlalchemy.orm import relation, mapper, sessionmaker from sqlalchemy.ext.declarative import declarative_base engine = create_engine('sqlite:///test.db', echo=True) meta = MetaData(bind=engine) property_values = Table('property_values', meta, Column('word_id', Integer, ForeignKey('words.id')), Column('property_id', Integer, ForeignKey('properties.id')), Column('value', String(20)) ) words = Table('words', meta, Column('id', Integer, primary_key=True), Column('name', String(20)), Column('freq', Integer) ) properties = Table('properties', meta, Column('id', Integer, primary_key=True), Column('name', String(20), nullable=False, unique=True) ) meta.create_all() class Word(object): def __init__(self, name, freq=1): self.name = name self.freq = freq class Property(object): def __init__(self, name): self.name = name mapper(Property, properties) Now I'd like to be able to do the following: Session = sessionmaker(bind=engine) s = Session() word = Word('foo', 42) word['bar'] = 'yes' # or word.bar = 'yes' ? s.add(word) s.commit() Ideally this should add 1|foo|42 to the words table, add 1|bar to the properties table, and add 1|1|yes to the property_values table. However, I don't have the right mappings and relations in place to make this happen. I get the sense from reading the documentation at http://www.sqlalchemy.org/docs/05/mappers.html#association-pattern that I want to use an association proxy or something of that sort here, but the syntax is unclear to me. I experimented with this: mapper(Word, words, properties={ 'properties': relation(Property, secondary=property_values) }) but this mapper only fills in the foreign key values, and I need to fill in the other value as well. Any assistance would be greatly appreciated.

  • User control loosing its contents when loaded programatically

    - by Phil
    I have a usercontrol which contains 2 repeaters and the code to populate them with data. If i manually insert this into the page then it works correctly, the repeaters populate etc. If I load it programatically using this method; 1) add class name to user control ClassName="ContentModule" 2) reference this in the default.aspx <%@ Reference Control="~/modules/content.ascx" %> 3) Add the code to my codebehind page_load to do the loading; Private loadmodule As ASP.ContentModule Try If themodule = "content" Then loadmodule = CType(LoadControl("~\Modules\Content.ascx"), ASP.ContentModule) Modulecontainer.Controls.Add(loadmodule) End If Catch ex As Exception Response.Write(ex.ToString & "<br />") End Try Nothing from within the usercontrol is loaded to the page. Although if I add some static text i.e "TEST" to the top of the usercontrol this is displayed ok on the default.aspx page. This makes me think that the control is loaded ok, but there is something in the way I have loaded it that is causing the contents to not properly execute. Very frustrating this one! Any help greatly appreciated!

  • Autoselect, focus and highlight a new NSOutlineView row

    - by coneybeare
    This is probably just lack of experience with the NSOutlineView but I can't see a way to do this. I have a NSOutlineView (implemented with the excellent PXSourceList) with an add button that is totally functional in the aspect that I save/write/insert/delete rows correctly. I do not use a NSTreeController, and I don't use bindings. I add the entity using the following code: - (void)addEntity:(NSNotification *)notification { // Create the core data representation, and add it as a child to the parent node UABaseNode *node = [[UAModelController defaultModelController] createBaseNode]; [sourceList reloadData]; for (int i = 0; i < [sourceList numberOfRows]; i++) { if (node == [sourceList itemAtRow:i]) { [sourceList selectRowIndexes:[NSIndexSet indexSetWithIndex:i] byExtendingSelection:NO]; [sourceList editColumn:0 row:i withEvent:nil select:NO]; break; } } } When the add button is pressed, a new row is inserted like this: If I click away, then select the row and press enter to edit it, it now looks like this: My question is: How can I programmatically get the same state (focus, selected, highlighted) the first time, to make the user experience better?

  • Generic callbacks

    - by bobobobo
    Extends So, I'm trying to learn template metaprogramming better and I figure this is a good exercise for it. I'm trying to write code that can callback a function with any number of arguments I like passed to it. // First function to call int add( int x, int y ) ; // Second function to call double square( double x ) ; // Third func to call void go() ; The callback creation code should look like: // Write a callback object that // will be executed after 42ms for "add" Callback<int, int, int> c1 ; c1.func = add ; c1.args.push_back( 2 ); // these are the 2 args c1.args.push_back( 5 ); // to pass to the "add" function // when it is called Callback<double, double> c2 ; c2.func = square ; c2.args.push_back( 52.2 ) ; What I'm thinking is, using template metaprogramming I want to be able to declare callbacks like, write a struct like this (please keep in mind this is VERY PSEUDOcode) <TEMPLATING ACTION <<ANY NUMBER OF TYPES GO HERE>> > struct Callback { double execTime ; // when to execute TYPE1 (*func)( TYPE2 a, TYPE3 b ) ; void* argList ; // a stored list of arguments // to plug in when it is time to call __func__ } ; So for when called with Callback<int, int, int> c1 ; You would automatically get constructed for you by < HARDCORE TEMPLATING ACTION > a struct like struct Callback { double execTime ; // when to execute int (*func)( int a, int b ) ; void* argList ; // this would still be void*, // but I somehow need to remember // the types of the args.. } ; Any pointers in the right direction to get started on writing this?

  • Ribbon not showing up with dynamically generated ribbon XML from the database

    - by ydobonmai
    I am trying to form ribbon XML with the data from the database and following is what I wrote:- XNamespace xNameSpace = "http://schemas.microsoft.com/office/2006/01/customui"; XDocument document = new XDocument(); document.Add( new XElement (xNameSpace+"customUI" , new XElement("ribbon" , new XElement("tabs")))); // more code to add the groups and the controls with-in the groups ....... // code below to add ribbon XML to the document and to add the relationship RibbonExtensibilityPart ribbonExtensibilityPart = myDoc.AddNewPart<RibbonExtensibilityPart>(); ribbonExtensibilityPart.CustomUI = new DocumentFormat.OpenXml.Office.CustomUI.CustomUI(ribbonXml.ToString()); myDoc.CreateRelationshipToPart(ribbonExtensibilityPart); I don't see any error executing the above. However, when I open the changed document, I dont see my ribbon added. I see following in the CustomUI/CustomUI.xml inside the word:- <?xml version="1.0" encoding="utf-8"?><customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui"> <ribbon xmlns=""> <tabs> ..... I am not sure how the "xmlns" attribute is getting added to the ribbon element. When I remove that attribute, the ribbon gets showed. Could anybody throw any idea on where am I going wrong?

  • Android map performance with > 800 overlays of KML data

    - by span
    I have some a shape file which I have converted to a KML file that I wish to read coordinates from and then draw paths between the coordinates on a MapView. With the help of this great post: How to draw a path on a map using kml file? I have been able to read the the KML into an ArrayList of "Placemarks". This great blog post then showed how to take a list of GeoPoints and draw a path: http://djsolid.net/blog/android---draw-a-path-array-of-points-in-mapview The example in the above post only draws one path between some points however and since I have many more paths than that I am running into some performance problems. I'm currently adding a new RouteOverlay for each of the separate paths. This results in me having over 800 overlays when they have all been added. This has a performance hit and I would love some input on what I can do to improve it. Here are some options I have considered: Try to add all the points to a List which then can be passed into a class that will extend Overlay. In that new class perhaps it would be possible to add and draw the paths in a single Overlay layer? I'm not sure on how to implement this though since the paths are not always intersecting and they have different start and end points. At the moment I'm adding each path which has several points to it's own list and then I add that to an Overlay. That results in over 700 overlays... Simplify the KML or SHP. Instead of having over 700 different paths, perhaps there is someway to merge them into perhaps 100 paths or less? Since alot of paths are intersected at some point it should be possible to modify the original SHP file so that it merges all intersections. Since I have never worked with these kinds of files before I have not been able to find a way to do this in GQIS. If someone knows how to do this I would love for some input on that. Here is a link to the group of shape files if you are interested: http://danielkvist.net/cprg_bef_cbana_polyline.shp http://danielkvist.net/cprg_bef_cbana_polyline.shx http://danielkvist.net/cprg_bef_cbana_polyline.dbf http://danielkvist.net/cprg_bef_cbana_polyline.prj Anyway, here is the code I'm using to add the Overlays.

  • database structure

    - by jindalsyogesh
    I have a table named ActivityRecording. This table currently has 500,000 records. I need to add a lot of new inputs that relates to activityrecording table. The relation of activityrecording with these new input fields is 1 to 0,1. So, what's going to happen on screen is when user fills the ActivityRecording data, he will then be taken to a new page and this page will show a form based on the user's input (from a dropdown named service) in activityrecording. There will 6 different kinds of form (each form will have 7-8 inputs which includes textareas of size 5kb, textboxes and checkboxes). So, for one activityrecording user will fill one out of 6 forms. There are two ways I know (there could be more), I can design the data structure: Add all the inputs from all these 6 forms into the activityrecording table. So, columns belonging to 5 of these forms will be null in this table, only columns belonging to one of the forms will have values The other way would be add 6 new tables (one for each form) and add 6 foreign key columns to activityrecording table. So, out of 6 foreign keys, 5 will be null and one will actually point to a table Which approach is a better data structure design? Please take into consideration that number of rows in this table are 500,000 and are expected to grow at a faster rate now.

  • Skip HTML escape in custom label_tag helper in Rail 3

  • Using a Context Menu to delete from a SQLite database in Android

    - by LordSnoutimus
    Hi, I have created a list view that displays the names and dates of items stored in a SQLite database, now I want to use a Context Menu to modify these items stored in the database such as edit the name, delete, and view. This is the code for the list view: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.listview); SQLiteDatabase myDB = null; myDB = this.openOrCreateDatabase(MY_DB_NAME, MODE_PRIVATE, null); Cursor cur = myDB.rawQuery("SELECT _id, trackname, tracktime" + " FROM " + MY_DB_TABLE, null); ListAdapter adapter = new SimpleCursorAdapter(this, R.layout.listview, cur, new String[] { Constants.TRACK_NAME, Constants.TRACK_TIME}, new int[] { R.id.text1, R.id.text2}); ListView list = (ListView)findViewById(R.id.list); list.setAdapter(adapter); registerForContextMenu(list); } and the Context Menu... public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); menu.setHeaderTitle("Track Options"); menu.add(0, CHANGE_NAME, 0, "Change name"); menu.add(0, VIEW_TRACK, 0, "View track"); menu.add(0, SEND_TRACK, 0, "Send track"); menu.add(0, DELETE_TRACK, 0, "Delete track"); } I have used a Switch statement to control the menu items.. public boolean onContextItemSelected(MenuItem item) { switch (item.getItemId()){ case CHANGE_NAME: changename(); return true; case DELETE_TRACK: deletetrack(); return true; default: return super.onContextItemSelected(item); } So how would I go ahead and map the deletetrack(); method to find the ID of the track stored in the database to the item that has been selected in the list view?

  • Insert code into a method - Java

    - by DutrowLLC
    Is there a way to automatically insert code into a method? I have the following and I would like to insert the indicated code: public class Person { Set<String> updatedFields = new LinkedHashSet<String>(); String firstName; public String getFirstName(){ return firstName; } boolean isFirstNameChanged = false; // Insert public void setFirstName(String firstName){ if( !isFirstNameChanged ){ // Insert isFirstNameChanged = true; // Insert updatedFields.add("firstName"); // Insert } // Insert this.firstName = firstName; } } I'm also not sure if I can the subset of the method name as a string from inside the method itself as indicated on the line where I add the fieldName as a string into the set of updated fields: updatedFields.add("firstName");. And I'm not sure how to insert fields into a class where I add the boolean field that tracks if the field has been modified or not before (for efficiency to prevent having to manipulate the Set): boolean isFirstNameChanged = false; It seems to most obvious answer to this would be to use code templates inside eclipse, but I'm concerned about having to go back and change the code later.

    I am facing issue with the global variable, when i run in the django development server it works fine, but in apache it doesn't work here is the code below: red= "/foodfolio3/test/" def showAddRecipe(request): #global objc if "userid" in request.session: objc["ErrorMsgURL"]= "" try: urlList= request.POST URL= str(urlList['url']) URL= URL.strip('http://') URL= "http://" + URL recipe= __addRecipeUrl__(URL) if (recipe == 'FailToOpenURL') or (recipe == 'Invalid-website-URL'): #request.session["ErrorMsgURL"]= "Kindly check URL, Please enter a valid URL" objc["ErrorMsgURL"]= "Kindly check URL, Please enter a valid URL" print "here global_context =", objc arurl= HttpResponseRedirect("/foodfolio3/add/import/") arurl['ErrorMsgURL']= objc["ErrorMsgURL"] #return HttpResponseRedirect("/foodfolio3/add/import/") #return render_to_response('addRecipeUrl.html', objc, context_instance = RequestContext(request)) return (arurl) else: objc["recipe"] = recipe return render_to_response('addRecipe.html', objc, context_instance = RequestContext(request)) except: objc["recipe"] = "" return render_to_response('addRecipe.html', objc, context_instance = RequestContext(request)) else: global red red= "/foodfolio3/add/" return HttpResponseRedirect("/foodfolio3/login") def showAddRecipeUrl(request): if "userid" in request.session: return render_to_response('addRecipeUrl.html', objc, context_instance = RequestContext(request)) else: global red red= "/foodfolio3/add/import/" return HttpResponseRedirect("/foodfolio3/login") def showLogin(request): obj = {} obj["error_message"] = "" obj["registered"] = "" if request.method == "POST": if (red == "/foodfolio3/test"): next= '/foodfolio3/recipes' else: next= red try: username = request.POST['username'] password = request.POST['password'] user = authenticate(username=username, password=password) except: user = authenticate(request=request) if user is not None: if user.is_active: login(request, user) request.session["userid"] = user.id # Redirect to a success page. return HttpResponseRedirect(next) this code works fine in django development server, but in apache, the url is getting redirected to '/foodfolio3/recipes'

  • XAttribute Generating strange namespaces

    - by Adam Driscoll
    I'm constructing an XElement with a couple attributes that have different namespaces. The code looks like this: var element = new XElement("SynchronousCommand", new XAttribute("{wcm}action", "add"), new XAttribute("{ns}id", Guid.NewGuid()), new XElement... ); The XML that is generated looks like this: <unattend xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:schemas-microsoft-com:unattend"> <SynchronousCommand d5p1:action="add" d5p2:id="c0f5fc6d-d407-4d3d-8a05-d84236cca2fb" xmlns:d5p2="ns" xmlns:d5p1="wcm"> ... </SynchronousCommand> </unattend> I'm just wondering if the auto-generated d5p2 is valid and why it is doing this. According to the XML standards here it seems like it would be valid. But why is it not: <unattend xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:schemas-microsoft-com:unattend"> <SynchronousCommand wcm:action="add" ns:id="c0f5fc6d-d407-4d3d-8a05-d84236cca2fb" > To generate the XML I'm doing this: public class unattend { public List<XElement> Any {get;} } var unattend = new unattend(); unattend.Add(element); serializer.Serialize(xmlWriter, unattend);

  • Lost Array After Validation Error

    - by Georges Kmeid
    I'm working on a CakePHP project and I have User, Post and Location models among others. User hasMany Location and Post belongsTo User so Location is not directly related to Post. This is my code in the Post controller: public function add() { if ($this->request->is('get')) { $this->loadModel('Location'); $this->set('locations', $this->Location->find('all', array('conditions' => array('user_id' => $this->Auth->user('id'))))); } ... } And this is my code in the posts/add view: <?php $i = 0; $j = 0; foreach ($locations as $location): $location_names[$i] = $location['Location']['name']; $i++; endforeach; echo "<select name=\"location\" onchange=\"select(this.value)\">"; echo "<option value=\"\">Select a saved location</option>"; foreach ($locations as $location): echo "<option value=\"" . $location['Location']['latitude'] . "," . $location['Location']['longitude'] . "\">" . $location_names[$j] . "</option>"; $j++; endforeach; ?> </select> If I enter a wrong value in one of the post inputs that has a validation rule in Post model, it redirects to the current add view, shows what is the validation error, but then the $locations array passed from controller to view disappears and can't use it in view and I get this error: Notice (8): Undefined variable: locations [APP\View\Posts\add.ctp, line 68]

  • How can I get this week's dates in Perl?

    - by ABach
    I have the following loop to calculate the dates of the current week and print them out. It works, but I am swimming in the amount of date/time possibilities in Perl and want to get your opinion on whether there is a better way. Here's the code I've written: #!/usr/bin/env perl use warnings; use strict; use DateTime; # Calculate numeric value of today and the # target day (Monday = 1, Sunday = 7); the # target, in this case, is Monday, since that's # when I want the week to start my $today_dt = DateTime->now; my $today = $today_dt->day_of_week; my $target = 1; # Create DateTime copies to act as the "bookends" # for the date range my ($start, $end) = ($today_dt->clone(), $today_dt->clone()); if ($today == $target) { # If today is the target, "start" is already set; # we simply need to set the end date $end->add( days => 6 ); } else { # Otherwise, we calculate the Monday preceeding today # and the Sunday following today my $delta = ($target - $today + 7) % 7; $start->add( days => $delta - 7 ); $end->add( days => $delta - 1 ); } # I clone the DateTime object again because, for some reason, # I'm wary of using $start directly... my $cur_date = $start->clone(); while ($cur_date <= $end) { my $date_ymd = $cur_date->ymd; print "$date_ymd\n"; $cur_date->add( days => 1 ); } As mentioned, this works, but is it the quickest or most efficient? I'm guessing that quickness and efficiency may not necessarily go together, but your feedback is very appreciated.

  • Counting problem C#

    - by MadBoy
    Hello, I've a bit of a problem. I'm adding numbers to ArrayList like 156, 340 (when it is TransferIn or Buy) etc and then i remove them doing it like 156, 340 (when it's TransferOut, Sell). Following solution works for that without a problem. The problem I have is that for some old data employees were entering sum's like 1500 instead of 500+400+100+500. How would I change it so that when there's Sell/TransferOut and there's no match inside ArrayList it should try to add multiple items from that ArrayList and find elements that combine into aggregate. ArrayList alNew = new ArrayList(); ArrayList alNewPoIle = new ArrayList(); ArrayList alNewCo = new ArrayList(); string tempAkcjeCzynnosc = (string) alInstrumentCzynnoscBezNumerow[i]; string tempAkcjeInId = (string) alInstrumentNazwaBezNumerow[i]; decimal varAkcjeCena = (decimal) alInstrumentCenaBezNumerow[i]; decimal varAkcjeIlosc = (decimal) alInstrumentIloscBezNumerow[i]; int index; switch (tempAkcjeCzynnosc) { case "Sell": case "TransferOut": index = alNew.IndexOf(varAkcjeIlosc); if (index != -1) { alNew.RemoveAt(index); alNewPoIle.RemoveAt(index); alNewCo.RemoveAt(index); } else { // Number without match encountred } break; case "Buy": case "TransferIn": alNew.Add(varAkcjeIlosc); alNewPoIle.Add(varAkcjeCena); alNewCo.Add(tempAkcjeInId); break; } }

  • How do I update a NSTableView when its data source has changed?

    - by Jergason
    I am working along with Cocoa Programming For Mac OS X (a great book). One of the exercises the book gives is to build a simple to-do program. The UI has a table view, a text field to type in a new item and an "Add" button to add the new item to the table. On the back end I have a controller that is the data source and delegate for my NSTableView. The controller also implements an IBAction method called by the "Add" button. It contains a NSMutableArray to hold the to do list items. When the button is clicked, the action method fires correctly and the new string gets added to the mutable array. However, my data source methods are not being called correctly. Here they be: - (NSInteger)numberOfRowsInTableView:(NSTableView *)aTableView { NSLog(@"Calling numberOfRowsInTableView: %d", [todoList count]); return [todoList count]; } - (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { NSLog(@"Returning %@ to be displayed", [todoList objectAtIndex:rowIndex]); return [todoList objectAtIndex:rowIndex]; } Here is the rub. -numberOfRowsInTableView only gets called when the app first starts, not every time I add something new to the array. -objectValueForTableColumn never gets called at all. I assume this is because Cocoa is smart enough to not call this method when there is nothing to draw. Is there some method I need to call to let the table view know that its data source has changed, and it should redraw itself?

  • Converting Python Script to Vb.NET - Involves Post and Input XML String

    - by Jason Shoulders
    I'm trying to convert a Python Script to Vb.Net. The Python Script appears to accept some XML input data and then takes it to a web URL and does a "POST". I tried some VB.NET code to do it, but I think my approach is off because I got an error back "BadXmlDataErr" plus I can't really format my input XML very well - I'm only doing string and value. The input XML is richer than that. Here is an example of what the XML input data looks like in the Python script: <obj is="MyOrg:realCommand_v1/" > <int name="priority" val="1" /> <real name="value" val="9.5" /> <str name="user" val="MyUserName" /> <reltime name="overrideTime" val="PT60S"/> </obj> Here's the Vb.net code I attempted to convert that: Dim reqparm As New Specialized.NameValueCollection reqparm.Add("priority", "1") reqparm.Add("value", "9.5") reqparm.Add("user", "MyUserName") reqparm.Add("overrideTime", "PT60S") Using client As New Net.WebClient Dim sTheUrl As String = "[My URL]" Dim responsebytes = client.UploadValues(sTheUrl, "POST", MyReqparm) Dim responsebody = (New System.Text.UTF8Encoding).GetString(responsebytes) End Using I feel like I should be doing something else. Can anyone point me to the right direction?

  • EF4 Code First - Many to many relationship issue

    - by Yngve B. Nilsen
    Hi! I'm having some trouble with my EF Code First model when saving a relation to a many to many relationship. My Models: public class Event { public int Id { get; set; } public string Name { get; set; } public virtual ICollection<Tag> Tags { get; set; } } public class Tag { public int Id { get; set; } public string Name { get; set; } public virtual ICollection<Event> Events { get; set; } } In my controller, I map one or many TagViewModels into type of Tag, and send it down to my servicelayer for persistence. At this time by inspecting the entities the Tag has both Id and Name (The Id is a hidden field, and the name is a textbox in my view) The problem occurs when I now try to add the Tag to the Event. Let's take the following scenario: The Event is already in my database, and let's say it already has the related tags C#, ASP.NET If I now send the following list of tags to the servicelayer: ID Name 1 C# 2 ASP.NET 3 EF4 and add them by first fetching the Event from the DB, so that I have an actual Event from my DbContext, then I simply do myEvent.Tags.Add to add the tags.. Problem is that after SaveChanges() my DB now contains this set of tags: ID Name 1 C# 2 ASP.NET 3 EF4 4 C# 5 ASP.NET This, even though my Tags that I save has it's ID set when I save it (although I didn't fetch it from the DB)
