  • Access custom label property at didSelectRowAtIndexPath.

    - by Mr. McPepperNuts
    I have a UILabel for each cell at cellForRowAtIndexPath. UILabel *cellLabel = [[UILabel alloc] initWithFrame:frame]; cellLabel.text = myString; I want to access that string "myString" at didSelectRowAtIndexPath using indexpath. NSString *anotherString = cell.textLabel.text; returns null. Now if at cellForRowAtIndexPath, I did something like cell.textLabel.text = theString; then the didSelectRowAtIndexPath returns the appropriate cell. My question is, how can I access the text in the UILabel I apply to the cell, at didSelectRowAtIndexPath? Also, logging the cell in didSelectRowAtIndexPath returns cell: <UITableViewCell: 0x5dcb9d0; frame = (0 44; 320 44); autoresize = W; layer = <CALayer: 0x5dbe670>> Edit: NSString *myString = [[results objectAtIndex:indexPath.row] valueForKey:@"name"]; //cell.textLabel.text = myString; CGFloat width = [UIScreen mainScreen].bounds.size.width - 50; CGFloat height = 20; CGRect frame = CGRectMake(10.0f, 10.0f, width, height); UILabel *cellLabel = [[UILabel alloc] initWithFrame:frame]; cellLabel.text = myString; cellLabel.textColor = [UIColor blackColor]; cellLabel.backgroundColor = [UIColor whiteColor]; cellLabel.textAlignment = UITextAlignmentLeft; cellLabel.font = [UIFont systemFontOfSize:14.0f]; [cell.contentView addSubview:cellLabel]; [cellLabel release]; return cell;

  • One-sided rounded buttons in Silverlight

    - by xarzu
    I want to make a collection of buttons in silverlight. They are in a collection that goes from left to right and the buttons are lined up so that they are touching on the left and right sides. Here is the rub: The collection has rounded corners but the buttons in between the end buttons in the collection do not have rounded ends. So basically, for the buttons on the far left and right side of the collection, they have to be somewhat special because they have to have one flat vertical side and one rounded side. Is this possible to do in silverlight without resorting to making a special bitmap for the end buttons? One idea I have is somehow declare a canvas with a bitmap background and then have overlapping ellipse and rectangle <Canvas Height="100" HorizontalAlignment="Left" Margin="189,381,0,0" VerticalAlignment="Top" Width="200" Background="Black"> <Rectangle Fill="#FFF4F4F5" HorizontalAlignment="Left" Stroke="Black" Width="58" Height="61" Canvas.Left="7" Canvas.Top="16" /> <Ellipse Fill="#FFF4F4F5" HorizontalAlignment="Left" Stroke="White" Width="65" StrokeThickness="0" Height="59" Canvas.Left="31" Canvas.Top="17" /> </Canvas>

  • QTableWidget::itemAt() returns seemingly random items

    - by Jordan Milne
    I've just started using Qt, so please bear with me. When I use QTableWidget-getItemAt(), it returns a different item from if I used currentItemChanged and clicked the same item. I believe it's necessary to use itemAt() since I need to get the first column of whatever row was clicked. Some example code is below: MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); QList<QString> rowContents; rowContents << "Foo" << "Bar" << "Baz" << "Qux" << "Quux" << "Corge" << "Grault" << "Garply" << "Waldo" << "Fred"; for(int i =0; i < 10; ++i) { ui->tableTest->insertRow(i); ui->tableTest->setItem(i, 0, new QTableWidgetItem(rowContents[i])); ui->tableTest->setItem(i, 1, new QTableWidgetItem(QString::number(i))); } } //... void MainWindow::on_tableTest_currentItemChanged(QTableWidgetItem* current, QTableWidgetItem* previous) { ui->lblColumn->setText(QString::number(current->column())); ui->lblRow->setText(QString::number(current->row())); ui->lblCurrentItem->setText(current->text()); ui->lblCurrentCell->setText(ui->tableTest->itemAt(current->column(), current->row())->text()); } For the item at 1x9, lblCurrentItem displays "9" (as it should,) whereas lblCurrentCell displays "Quux". Am I doing something wrong?

  • Browser relative positioning with jQuery and CutyCapt

    - by Acoustic
    I've been using CutyCapt to take screen shots of several web pages with great success. My challenge now is to paint a few dots on those screen shots that represent where a user clicked. CutyCapt goes through a process of resizing the web page to the scroll width before taking a screen shot. That's extremely useful because you only get content and not much (if any) of the page's background. My challenge is trying to map a user's mouse X coordinates to the screen shot. Obviously users have different screen resolutions and have their browser window open to different sizes. The image below shows 3 examples with the same logo. Assume, for example, that the logo is 10 pixels to the left edge of the content area (in red). In each of these cases, and for any resolution, I need a JavaScript routine that will calculate that the logo's X coordinate is 10. Again, the challenge (I think) is differing resolutions. In the center-aligned examples, the logo's position, as measured from the left edge of the browser (in black), differs with changing browser size. The left-aligned example should be simple as the logo never moves as the screen resizes. Can anyone think of a way to calculate the scrollable width of a page? In other words, I'm looking for a JavaScript solution to calculate the minimum width of the browser window before a horizontal scroll bar shows up. Thanks for your help!

  • [hibernate - jpa] @CollectionOfElements without create the apposite table

    - by blow
    Hi all. I have this: Municipality class @Entity public class Municipality implements Serializable { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id; private String country; private String province; private String name; @Column(name="cod_catasto") private String codCatastale; private String cap; @CollectionOfElements private List<Address> addressList; public Municipality() { } ... Address class @Embeddable public class Address implements Serializable { @ManyToOne(fetch=FetchType.LAZY) @Cascade(CascadeType.SAVE_UPDATE) private Municipality municipality; @Column(length=45) private String address; public Address() { } ... Address is embedded in another class Person. When i save an instance of Person, hibernate create 3 tables: PERSON, MUNICIPALITY and MUNICIPALITY_ADDRESSLIST. MUNICIPALITY_ADDRESSLIST contains 2 fields: MUNICIPALITY_ID (FK) and STREET. I don't want this table, i only want the ID of table MUNICIPALITY into table PERSON(that embeds Address), what should i do? I tried to add @JoinTable in Municipality entity like this: @CollectionOfElements @JoinTable(name="person") private List<Address> addressList; It partially worked, but i cant choose the column name of table PERSON that contains ID of the table MUNICIPALITY, it is, by hibernate choose, simply "MUNICIPALITY_ID"... Thbaks.

  • Having an issue with Nullable MySQL columns in SubSonic 3.0 templates

    - by omegawkd
    Looking at this line in the Settings.ttinclude string CheckNullable(Column col){ string result=""; if(col.IsNullable && col.SysType !="byte[]" && col.SysType !="string") result="?"; return result; } It describes how it determines if the column is nullable based on requirements and returns either "" or "?" to the generated code. Now I'm not too familiar with the ? nullable type operator but from what I can see a cast is required. For instance, if I have a nullable integer MySQL column and I generate the code using the default template files it returns a line similar to this: int? _User_ID; When trying to compile the project I get the error: Cannot implicitly convert type 'int?' to 'int'. An explicit conversion exists (are you missing a cast?) I checked teh Settings files for the other database types and they all seems to have the same routine. So my question is, is this behaviour expected or is this a bug? I need to solve it one way or the other before I can procede. Thanks for your help.

  • vertical align of some inline-block divs with different content

    - by Jan Möller
    i want to center some inline-block divs. I want to create a responsive design, so if the screen size is too small, the horizontal elements should be under each other. How can i center them vertical, so they are side by side without a difference in height? (See fiddle). Moveover those elements should be verticaly centered, if the screen size is too small. http://jsfiddle.net/5dpRs/52/ CSS .repeat { display:inline-block; border-style:solid; border-width:2px; height:50px; width:50px; } #content { border-style:solid; border-width:2px; text-align:center; } HTML <div id="content"> <div class="repeat"> <p>hello</p> </div> <div class="repeat"> </div> </div> Thank you :)

  • Does Internet Explorer 7 have a CSS parsing issue with the "background-image" property?

    - by user312003
    Having CSS layout issues with Internet Explorer 7 (big surprise). Upon using the Developer Tools to inspect the CSS, I discovered that some properties defined in the stylesheet are not appearing in the parsed CSS structure... THEN I saw THIS being shown as the parsed value for the background-image property: background-image : url(/trunk/httpdocs/images/layout/HCBL_Homepage_01.jpg); WIDTH: 1200px; pretty much obliterating the width that was defined property. The actual code in the CSS file for this element: div#header { width: 1200px; height: 100px; margin-left: auto; margin-right: auto; background-image: url('/trunk/httpdocs/images/layout/HCBL_Homepage_01.jpg'); background-repeat: no-repeat; } If anyone could offer any insight, or provide a link describing this problem (and maybe a workaround...) I would be very appreciative. Also, I am only interested in this from a parsing of the stylesheet and CSS syntax perspective. I am not concerned with rendering and display issues at the moment; I simply want to get IE 7 (and I have a feeling IE 6 will have similar issues) to recognize and parse ALL of the CSS properties that have been defined in the stylesheet. Thanks in advance guys!

  • Cursor on Path doesn't appear in SilverLight

    - by Rahul Soni
    I am trying to draw a circle with a glass effect using Alpha. I am successful in creating that by using the below XAML. The cursor changes to Hand for the Ellipses, but it doesn't affect Path.

  • How to implement custom JSF component for drawing chart?

    - by Roman
    I want to create a component which can be used like: <mc:chart data="#{bean.data}" width="200" height="300" /> where #{bean.data} returns a collection of some objects or chart model object or something else what can be represented as a chart (to put it simple, let's assume it returns a collection of integers). I want this component to generate html like this: <img src="someimg123.png" width="200" height="300"/> The problem is that I have some method which can receive data and return image, like: public RenderedImage getChartImage (Collection<Integer> data) { ... } and I also have a component for drawing dynamic image: <o:dynamicImage width="200" height="300" data="#{bean.readyChartImage}/> This component generates html just as I need but it's parameter is array of bytes or RenderedImage i.e. it needs method in bean like this: public RenderedImage getReadyChartImage () { ... } So, one approach is to use propertyChangedListener on submit to set data (Collection<Integer>) for drawing chart and then use <o:dynamicImage /> component. But I'd like to create my own component which receives data and draws chart. I'm using facelets but it's not so important indeed. Any ideas how to create the desired component? P.S. One solution I was thinking about is not to use <o:dynamicImage/> and use some servlet to stream image. But I don't know how to implement that correctly and how to tie jsf component with servlet and how to save already built chart images (generating new same image for each request can cause performance problems imho) and so on..

  • How to- NSAttributedString to CGImageRef

    - by kroko
    Hello! I'm writing a QuickLook plugin. Well, everything works. Just want to try it make better ;). Thus the question. Here is a function that returns thumbnail image and that I'm using now. QLThumbnailRequestSetImageWithData( QLThumbnailRequestRef thumbnail, CFDataRef data, CFDictionaryRef properties); ); http://developer.apple.com/mac/library/documentation/UserExperience/Reference/QLThumbnailRequest_Ref/Reference/reference.html#//apple_ref/c/func/QLThumbnailRequestSetImageWithData Right now I'm creating a TIFF - encapsulated it into NSData. An example // Setting CFDataRef CGSize thumbnailMaxSize = QLThumbnailRequestGetMaximumSize(thumbnail); NSMutableAttributedString *attributedString = [[[NSMutableAttributedString alloc] initWithString:@"dummy" attributes:[NSDictionary dictionaryWithObjectsAndKeys: [NSFont fontWithName:@"Monaco" size:10], NSFontAttributeName, [NSColor colorWithCalibratedRed:0.0 green:0.0 blue:0.0 alpha:1.0], NSForegroundColorAttributeName, nil] ] autorelease]; NSImage *thumbnailImage = [[[NSImage alloc] initWithSize:NSMakeSize(thumbnailMaxSize.width, thumbnailMaxSize.height)] autorelease]; [thumbnailImage lockFocus]; [[NSColor whiteColor] set]; NSRectFill(NSMakeRect(0, 0, thumbnailMaxSize.width, thumbnailMaxSize.height)); [attributedString drawInRect:NSMakeRect(0, 0, thumbnailMaxSize.width, thumbnailMaxSize.height)]; [thumbnailImage unlockFocus]; (CFDataRef)[thumbnailImage TIFFRepresentation]; // This is data // Setting CFDictionaryRef (CFDictionaryRef)[NSDictionary dictionaryWithObjectsAndKeys:@"kUTTypeTIFF", (NSString *)kCGImageSourceTypeIdentifierHint, nil ]; // this is properties However QuickLook provides another function to return thumbnail image, namely QLThumbnailRequestSetImage( QLThumbnailRequestRef thumbnail, CGImageRef image, CFDictionaryRef properties); ); http://developer.apple.com/mac/library/documentation/UserExperience/Reference/QLThumbnailRequest_Ref/Reference/reference.html#//apple_ref/c/func/QLThumbnailRequestSetImage I have a feeling that passing CGImage to the QL instead of TIFF data would help in speeding things up. However- I have never worked with CG context before. I know, the documentation is there :), but anyways- could anyone give an example how to turn that NSAttributed string into CGImageRef. An example is worth 10 times reading the documentation ;) Any help appreciated. Thanks in advance!

  • Handling missing/incomplete data in R--is there function to mask but not remove NAs?

    - by doug
    As you would expect from a DSL aimed at data analysis, R handles missing/incomplete data very well, for instance: Many R functions have an 'na.rm' flag that you can set to 'T' to remove the NAs: mean( c(5,6,12,87,9,NA,43,67), na.rm=T) But if you want to deal with NAs before the function call, you need to do something like this: to remove each 'NA' from a vector: vx = vx[!is.na(a)] to remove each 'NA' from a vector and replace it w/ a '0': ifelse(is.na(vx), 0, vx) to remove entire each row that contains 'NA' from a data frame: dfx = dfx[complete.cases(dfx),] All of these functions permanently remove 'NA' or rows with an 'NA' in them. Sometimes this isn't quite what you want though--making an 'NA'-excised copy of the data frame might be necessary for the next step in the workflow but in subsequent steps you often want those rows back (e.g., to calculate a column-wise statistic for a column that has missing rows caused by a prior call to 'complete cases' yet that column has no 'NA' values in it). to be as clear as possible about what i'm looking for: python/numpy has a class, 'masked array', with a 'mask' method, which lets you conceal--but not remove--NAs during a function call. Is there an analogous function in R?

    I'm currently working on a C# wrapper to work with Dallmeier Common API light. See previous posting: http://stackoverflow.com/questions/2430089/c-wrapper-and-callbacks I've got pretty much everything 'wrapped' but I'm stuck on wrapping a callback which contains an array of three pointers & an array integers: dlm_setYUVDataCllback int(int SessionHandle, void (*callback) (long IPlayerID, unsigned char** yuvData, int* pitch, int width, int height, int64_t ts, char* extData)) Function Set callback, to receive current YUV image. Arguments SessionHandle: handle to current session. Return PlayerID (see callback). Callback - IPlayerId: id to the Player object - yuvData: array of three pointers to Y, U and V part of image The YUV format used is YUV420 planar (not packed). char *y = yuvData[0]; char *u = yuvData[1]; char *v = yuvData[2]; - pitch: array of integers for pitches for Y, U and V part of image - width: intrinsic width of image. - height - ts : timestamp of current frame - extData: additional data to frame How do I go about wrapping this in c#? Any help is much appreciated.

  • My 3D object (opengl es) is disappearing behind the iPhone camera view

    - by KLC
    I have an augmented reality iPhone app that I am converting from Core Animation to OpenGL ES 1.1. I have added code that has been modified from the Apple OpenGL template. My problem is that my 3D object , when translating along the negative Z-axis (away from the user), appears to disappear into the camera view, until its completely gone. I have experimented with several solutions, but to no avail. What I have determined: Using the 3D icosahedron from Jeff Lamarche's blog here, the object starts it at 0,0,0 and then translates with decreasing z coordinates. By the time the z value reaches -2.0f, the object is gone. It appears as if it is disappearing behind the camera view. This is how I set my frustrum & viewport (unchanged from Apple's code) glMatrixMode(GL_PROJECTION); size = zNear * tanf(DEGREES_TO_RADIANS(fieldOfView) / 2.0); //Grab the size of the screen CGRect rect = self.bounds; glFrustumf(-size, size, -size / (rect.size.width / rect.size.height), size / (rect.size.width / rect.size.height), zNear, zFar); glViewport(0, 0, rect.size.width, rect.size.height); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); What I have tried: The camera view is the main view and several other views are added to it as subviews, including the openGLView. I have commented those views out for test purposes. I have applied CATransforms to move the openGLView in the z direction -500 and +500, and done the same to the camera view. I have also changed the zFar in the above code to 1.0f, and it still disappears at z position of -2.0, which doesn't make sense (shouldn't it disappear at z=1.0?) My experimentation has got me more confused than when I started ( which usually means I am missing a key piece, but I can't figure out what). Thanks for your help.

  • IE7 div floating bug

    - by Michael Frey
    I have the following <div id="border" style="width:100%; border:8px solid #FFF"> <div id="menu" style="width:250px; float:left;" > Some menu </div> <div id="content" style="padding-left:270px; width:520px;" > Main page content </div> </div> This gives me a left aligned menu and the content to the right of it, all surrounded by a border. On all browsers including IE8 it displays correctly. But on IE7 the content only starts below the menu, and leaves a big open space to the right of the menu. I have searched all kind of solutions and tried all kinds of combinations of right, left, none for float. clearing left right both. It always displays different on the browsers.

  • How do I add ROW_NUMBER to a LINQ query or Entity?

    - by Whozumommy
    I'm stumped by this easy data problem. I'm using the Entity framework and have a database of products. My results page returns a paginated list of these products. Right now my results are ordered by the number of sales of each product, so my code looks like this: return Products.OrderByDescending(u => u.Sales.Count()); This returns an IQueryable dataset of my entities, sorted by the number of sales. I want my results page to show the rank of each product (in the dataset). My results should look like this: Page #1 1. Bananas 2. Apples 3. Coffee Page #2 4. Cookies 5. Ice Cream 6. Lettuce I'm expecting that I just want to add a column in my results using the SQL ROW_NUMBER variable...but I don't know how to add this column to my results datatable. My resulting page does contain a foreach loop, but since I'm using a paginated set I'm guessing using that number to fake a ranking number would NOT be the best approach. So my question is, how do I add a ROW_NUMBER column to my query results in this case?

  • Is it possible to add JPA annotation to superclass instance variables?

    - by Kristofer Borgstrom
    Hi, I am creating entities that are the same for two different tables. In order do table mappings etc. different for the two entities but only have the rest of the code in one place - an abstract superclass. The best thing would be to be able to annotate generic stuff such as column names (since the will be identical) in the super class but that does not work because JPA annotations are not inherited by child classes. Here is an example: public abstract class MyAbstractEntity { @Column(name="PROPERTY") //This will not be inherited and is therefore useless here protected String property; public String getProperty() { return this.property; } //setters, hashCode, equals etc. methods } Which I would like to inherit and only specify the child-specific stuff, like annotations: @Entity @Table(name="MY_ENTITY_TABLE") public class MyEntity extends MyAbstractEntity { //This will not work since this field does not override the super class field, thus the setters and getters break. @Column(name="PROPERTY") protected String property; } Any ideas or will I have to create fields, getters and setters in the child classes? Thanks, Kris

The error comes at line 7 line from bottom (Bitmap.createBitmap(...);). public Bitmap[] getPieces(Bitmap bmp) { Bitmap[] bmps = new Bitmap[9]; int width = bmp.getWidth(); int height = bmp.getHeight(); int rows = 3; int cols = 3; int cellHeight = height / rows; int cellWidth = width / cols; int piece = 0; for (int x = 0; x <= width; x += cellWidth) { for (int y = 0; y <= height; y += cellHeight) { Bitmap b = Bitmap.createBitmap(bmp, x, y, cellWidth, cellHeight, null, false); bmps[piece] = b; piece++; } } return bmps; }

  • Temporary users table or legitimate users table?

    - by John
    I have a freelance web application that lets users register for events. In my database, I have a t_events_applicants table with the column t_events_applications.user_id with a foreign key constraint linked to the t_users.user_id column. So this means only users who have registered with my web application can register for my web application's events. My client would now like to allow non-registered users, users who do not have an entry in my t_user table, to register for events. These non-registered users only need to provide their name and email address to register for events. Should I create a t_temporary_user table with columns name and email and then remove the t_events_applicants.user_id fk constraint? Or should I add un-registered users to the t_user table and then add a column called t_user.type where type can be 'registered' or 'non-registered'? How do I decide which approach to go with? A lot of times, I hesitate with either approach. I ask myself, "What if at a later time, a temporary user is allowed to become a fully registered user? Then maybe I should have only a t_user table. But then I also don't feel good about storing a lot of temporary users in t_user."

  • Change with jQuery a cell of a table created with JSF

    - by perissf
    From within a xhtml page created with JSF, I need to use JavaScript / jQuery for changing the content of a cell of a table. I know how to assign a unique id to the div containing the table, and to the tbody. I can also assign unique class names to the div itself and to the target column. The target row is identified by the data-rk attribute. <div id="tabForm:centerTabView:personsTable" class="ui-datatable ui-widget personsTable"> <table role="grid"> <tbody id="tabForm:centerTabView:personsTable_data" > <tr data-rk="2" > <td ... /> <td class="lastNameCol" role="gridcell"> <div> To Be Edited </div> </td> <td ... /> </tr> <tr ... /> </tbody> </table> </div> I have tried with many combinations of different jQuery selectors, but I am really lost. I need to search my target row and my target column inside that particular div or inside that particular table, because the xhtml page may contain other tables with different unique ids (and accidentally with the same row and column ids).

  • Oracle doesn't remove cursors after closing result set

  • why DataColumn AllowDbNull is true even if oracle db does not allow null

    - by matti
    Hi. I have column SomeId in table SomeLink. When I look with tOra or Sql Plus Worksheet both state: tOra: Column name Data type Default Null Comment SOMEID INTEGER {null} NOT NULL {null} Sql Plus: SOMEID NOT NULL NUMBER(38) I have authored a method that's intended to give default values to all NOT NULL fields that don't have values: public static void GetDefaultValuesForNonNullColumns(DataRow row) { foreach(DataColumn col in row.Table.Columns) { if (Convert.IsDBNull(row[col]) && !col.AllowDBNull) { if (ColumnIsNumeric(col.DataType)) row[col] = 0; else if (col.DataType == typeof(DateTime)) row[col] = DateTime.Now; else if (col.DataType == typeof(String)) row[col] = string.Empty; else if (col.DataType == typeof(Char)) row[col] = ' '; else throw new Exception(string.Format("Unsupported column type: {0}", col.DataType)); } } } When SOMEID is handled in loop the AllowDBNull = true. I really can't understand. The table is created in DataSet like this: _someLinkAdptr = _dbFactory.CreateDataAdapter(); _someLinkAdptr.SelectCommand = _dbFactory.CreateCommand(); _someLinkAdptr.SelectCommand.Connection = _cnctn; _someLinkAdptr.SelectCommand.CommandText = GetSomeLinkSelectTxtAndParams(_someLinkAdptr.SelectCommand, UndefinedValue.ToString(), UndefinedValue.ToString()); Select command returns no rows. The idea is that I can then use commandbuilder to get InsertCommand without building it myself. The row is added to dataset's table like this: private static void CreateDocLink(int anId, int anotherId) { DataRow row = _someDataSet.Tables["SomeLink"].NewRow(); row["AnId"] = anId; row["AnotherId"] = anotherId; Utility.GetDefaultValuesForNonNullColumns(row); _someDataSet.Tables["SomeLink"].Rows.Add(row); } When DataAdapter is updated to oracle db I get: ORA-01400: cannot insert NULL into (SOMESCHEMA.SOMELINK.SOMEID) Cheers & BR -Matti

  • [EF 4 POCO] Problem with INSERT...

    - by Darmak
    Hi all, I'm so frustrated because of this problem, you have no idea... I have 2 classes: Post and Comment. I use EF 4 POCO support, I don't have foreign key columns in my .edmx model (Comment class doesn't have PostID property, but has Post property) class Comment { public Post post { get; set; } // ... } class Post { public virtual ICollection<Comment> Comments { get; set; } // ... } Can someone tell me why the code below doesn't work? I want to create a new comment for a post: Comment comm = context.CreateObject<Comment>(); Post post = context.Posts.Where(p => p.Slug == "something").SingleOrDefault(); // post != null, so don't worry, be happy // here I set all other comm properties and... comm.Post = post; context.AddObject("Comments", comm); // Exception here context.SaveChanges(); The Exception is: Cannot insert the value NULL into column 'PostID', table 'Blog.Comments'; column does not allow nulls. INSERT fails. ... this 'PostID' column is of course a foreign key to the Posts table. Any help will be appreciated!
