  • Problems setting vertical scrollbar value in a datagrid (old one, not the better DataGridView).

    - by user365581
    I need to save the selected row and the vertical scrollBar's position after a refresh. This is how I do it: int currRow = myGrid.CurrentRowIndex; int vScrollPos = ((ScrollBar)myGrid.Controls[1]).Value // some code that refreshes the data among other things myGrid.CurrentRowIndex = currRow; // this sets the property myGrid.Select(currRow); // this selects in UI (both commands required) ((ScrollBar)myGrid.Controls[1]).Value = vScrollPos; Here's my problem: The grid always jumps to a place where the selected row is at the bottom. setting the current row makes it happen - similar to EnsureVisible of newer grid implementations. But after that there's the vScrollBar repositioning - and it just doesn't work right. In debug I see that the scroll bar value gets updated. In the UI, if I hit the down/up arrow on the scrollbar it suddenly jumps to the right place - But if I don't click anything the grid is just in the wrong position. I tried refreshing the grid/scroll bar to force a redraw, but it doesn't help. The actual grid position is just not in sync with the vertical ScrollBar's value. Any ideas?

  • Flash Builder 4 "includeIn" property causing design view error

    - by Chris
    I am creating a custom TextInput component that will define an "error" state. I have extended the TextInput class to change the state to "error" if the errorString property's length is greater than 0. In the skin class, I have defined an "error" state, and added some logic to detect the size and position of the error icon. However, if I have this code at the same time I use the "includeIn" property in the bitmap image tag, I get a design view error. If I either A) Only include that code with no "includeIn" property set, it works or B) dont include the code to set the icon size and position and only use the "includeIn" property, it works. Any ideas what could be causing the design view problem when I use both the "includeIn" property and the icon size/position code at the same time? TextInput Class: package classes { import spark.components.TextInput; public class TextInput extends spark.components.TextInput { [SkinState("error")]; public function TextInput() { super(); } override public function set errorString( value:String ):void { super.errorString = value; invalidateSkinState(); } override protected function getCurrentSkinState():String { if (errorString.length>0) { return "error"; } return super.getCurrentSkinState(); } } } TextInput Skin File: override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void { //THIS IS THE CODE THAT SEEMS TO BE CAUSING THE PROBLEM if(getStyle("iconSize") == "large") { errorIcon.right = -12; errorIcon.source = new errorIconLg(); } else { errorIcon.right = -5; errorIcon.source = new errorIconSm(); } super.updateDisplayList(unscaledWidth, unscaledHeight); } </fx:Script> <s:states> <s:State name="normal"/> <s:State name="disabled"/> <s:State name="error"/> </s:states> //If I remove the problem code above or if I take out the includeIn //property here, it works <s:BitmapImage id="errorIcon" verticalCenter="0" includeIn="error" /> </s:SparkSkin>

  • IE 7 floated div auto-clearing next element ?

    - by schweb-design-llc
    Hello, I'm having trouble with the following example. Background: I first have a element floated to the right with an image output inside it. I then have a element with other content within it. In FF and IE 8, as expected, the .images div floated to the right displays floated to the right pushing the content within the .product-body div to the left nicely. The problem: But when viewed in IE 7 compatibility mode, the .product-body div is cleared underneath the .images div and thus the .images div does not fall nicely to the right as expected. IT does this regardless of whether or not i have clear:none; on the .broduct-body div. Please see the example at www.hotelmarketingbudget.com Look at the source code there at the div element #content-body to see these divs. Feel free to use Firebug or IE Dev toolbar or whatnot to check this out. The relevant CSS: content-body{ width:auto; height:auto; position:relative; margin:0 auto; } .product-group .images { float:right; width:auto; height:auto; position:relative; margin:0 auto; margin-left:15px; } .product-group .product-body { width:auto; height:auto; position:relative; margin:0 auto; } I've spent hours already trying to figure out how to fix this- googling, reading other threads here on stackoverflow, but alas i cannot find any solutions and it's hard to know what words to even search with. I'm really hoping this is just some brain-fart on my part. Any advice or ideas or questions would be GREATLY appreciated!

  • How do I unbind another jQuery function on .click()?

    - by Mike Barwick
    I have this script that run to fix my menu bar to the browser on scroll. Nothing really needs to change here (works as it should). However, you may need it... var div = $('#wizMenuWrap'); var editor = $('#main_wrapper'); var start = $(div).offset().top; $(function fixedPackage(){ $.event.add(window, "scroll", function() { var p = $(window).scrollTop(); $(div).css('position',((p)>start) ? 'fixed' : 'static'); $(div).css('top',((p)>start) ? '0px' : ''); //Adds TOP margin to #main_wrapper (required) $(editor).css('position',((p)>start) ? 'relative' : 'static'); $(editor).css('top',((p)>start) ? '88px' : ''); }); }); Now for the issue at hand. I have another script function that calls a modal pop-up (which again works as it should). However, it's not slick from a UI perspective when I scroll the page when the modals open. So I want to disable the script above when the modal script below is called. In other words, when I click to open the modal pop-up, the script above shouldn't work. $(function () { var setUp = $('.setupButton'); // SHOWS SPECIFIED VIEW $(setUp).click(function () { $('#setupPanel').modal('show'); //PREVENTS PACKAGE SELECT FIXED POSITION ON SCROLL $(setUp).unbind('click',fixedPackage); }); }) As you can see above, I tried to unbind the scroll function (the first code snippet), but this is not correct. These two scripts are in two separate js libraries.

  • Using Gtk.TreeDragSource.drag_data_get()

    - by knutsondc
    I have a simple Gtk.TreeView with a Gtk.ListStore with four columns as the model. I want to be able to drag and drop rows within the TreeView and track row insertions, changes and deletions as they happen so I can implement undo/redo to drag and drop operations. I'm using PyGObject 3 and Python 3.2. I thought that using methods under the Gtk.TreeDragSource and Gtk.TreeDragDest interfaces would suit my needs perfectly, with Gtk.TreeDragSource.drag_data_get() in my drag_data_get handler and Gtk.TreeDragDest.drag_data_received() or Gtk.tree_get_row_drag_data() in my drag_data_received handler. Basically, what I've tried looks something like this: def drag_data_received(self, treeview, context, x, y, selection, info, time): treeselection = tv.get_selection() model, my_iter = treeselection.get_selected() path = model.get_path(my_iter) result = Gtk.TreeDragSource.drag_data_get(path, selection) def drag_data_received(self, tv, context, x, y, selection, info, time): result, model, row = Gtk.tree_get_row_drag_data(selection) my_iter = model.get_iter(row) data = [model.get_value(my_iter, i) for i in range(model.get_n_columns())] drop_info = tv.get_dest_row_at_pos(x, y) if drop_info: path, position = drop_info my_iter = model.get_iter(path) if (position == Gtk.TreeViewDropPosition.BEFORE or position == Gtk.TreeViewDropPosition.INTO_OR_BEFORE): model.insert_before(my_iter, [data]) else: model.insert_after(my_iter, [data]) else: model.append([data]) if context.get_actions() == Gdk.DragAction.MOVE|Gdk.DragAction.DEFAULT: context.finish(True, True, time) return This fails spectacularly - when Python hits the call to Gtk.TreeDragSource.drag_data_get(), Python crashes and my program window swiftly disappears. I don't even get to the drag_data_received handler. Can anyone point me to some example code showing how these methods using the TreeDragSource and TreeDragDest interfaces work? Any help much appreciated!

  • CSS Equivalent of Table Rowspan with Fluid Height

    - by Gabe
    I'm trying to accomplish the following using CSS: <table border="1" width="300px"> <tr> <td rowspan="2">This row should equal the height (no fixed-height allowed) of the 2 rows sitting to the right.</td> <td>Here is some sample text. And some additional sample text.</td> </tr> <tr> <td>Here is some sample text. And some additional sample text.</td> </tr> </table> The examples I've seen for accomplishing this utilize fixed heights or allow the content to wrap around the left column. Is there an elegant way to accomplish this using CSS?

  • Showing items as images in a WPF ListView

    - by Joan Venge
    So I have binded a List to a ListView where the List has items of type Album, where it has lots of properties including .Cover, which I is an image on disk. Well since I don't know what type of image is needed and how they have to be loaded (I only know using Image types for Winforms), I don't know the type yet. Can someone show or post me a quick sample where it shows this sort of items being shown as images of a certain fixed size using their .Cover property? In essence this would show: What type .Cover should be How to open images from disk for WFP (assuming it's different than Winforms image loading) How to show them on a ListView as images of a certain fixed size, scaling the images if necessary

  • Resolving MSB3247 - Found conflicts between different versions of the same dependent assembly

    - by David Gardiner
    A .NET 3.5 solution ended up with this warning when compiling with msbuild. Sometimes NDepend might help out but in this case it didn't give any further details. Like Bob I ended up having to resort to opening each assembly in ILDASM until I found the one that was referencing an older version of the dependant assembly. I did try using MSBUILD from VS 2010 Beta 2 (as the Connect article indicated this was fixed in the next version of the CLR) but that didn't provide any more detail either (maybe fixed post Beta 2) Is there a better (more automated) approach?

  • minimum height problem

    - by Hellnar
    Hello, assume I have a such html order <div id="header">>Header(logo, navigation menus etc)will be here, fixed height </div> <div id="content"> Dynamic content with different length will be here. </div> <div id="footer"> Footer of the page here, fixed height </div> Now as you can see, it is only the content div which will be changing in size as the length changes. I want to make sure the screen is used even if the height of the content is less than to fill the whole. (in other words minimum height of the content will be screen (height in pixel) - ( (height of header) + (height of footer) ) Now I can see that min-widht can be used but it is not supported with IE, how can I achieve this issue ?

  • UIToolbar UIBarButtonItem Alignment question

    - by Luther Baker
    I need to create a UIToolbar that has two UIBarButtonItems. The 1st button must be centered and the 2nd item must be right aligned. I understand and use Flexible spacing and it works great when I need to balance buttons across the UIToolbar, but with only two buttons, I can't seem to perfectly center the middle button. I've even initialized the view.toolbarItems array with NSArray *items = [[NSArray alloc] initWithObjects:fixed, flex, center_button, flex, right_button, nil]; and set fixed.width = right_button.width ... but still, the center_button is never perfectly centered.

  • converting between struct and byte array

    - by chonch
    his question is about converting between a struct and a byte array. Many solutions are based around GCHandle.Alloc() and Marshal.StructureToPtr(). The problem is these calls generate garbage. For example, under Windows CE 6 R3 about 400 bytes of garbarge is made with a small structure. If the code below could be made to work the solution could be considered cleaner. It appears the sizeof() happens too late in the compile to work. public struct Data { public double a; public int b; public double c; } [StructLayout(LayoutKind.Explicit)] public unsafe struct DataWrapper { private static readonly int val = sizeof(Data); [FieldOffset(0)] public fixed byte Arr[val]; // "fixed" is to embed array instead of ref [FieldOffset(0)] public Data; // based on a C++ union }

  • IronPython and Nodebox in C#

    - by proxylittle
    My plan: I'm trying to setup my C# project to communicate with Nodebox to call a certain function which populates a graph and draws it in a new window. Current situation: [fixed... see Update2] I have already included all python-modules needed, but im still getting a Library 'GL' not found it seems that the pyglet module needs a reference to GL/gl.h, but can't find it due to IronPython behaviour. Requirement: The project needs to stay as small as possible without installing new packages. Thats why i have copied all my modules into the project-folder and would like to keep it that or a similar way. My question: Is there a certain workaround for my problem or a fix for the library-folder missmatch. Have read some articles about Tao-Opengl and OpenTK but can't find a good solution. Update1: Updated my sourcecode with a small pyglet window-rendering example. Problem is in pyglet and referenced c-Objects. How do i include them in my c# project to be called? No idea so far... experimenting alittle now. Keeping you updated. SampleCode C#: ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null); ScriptRuntime runtime = new ScriptRuntime(setup); ScriptEngine engine = Python.GetEngine(runtime); ScriptSource source = engine.CreateScriptSourceFromFile("test.py"); ScriptScope scope = engine.CreateScope(); source.Execute(scope); SampleCode Python (test.py): from nodebox.graphics import * from nodebox.graphics.physics import Vector, Boid, Flock, Obstacle flock = Flock(50, x=-50, y=-50, width=700, height=400) flock.sight(80) def draw(canvas): canvas.clear() flock.update(separation=0.4, cohesion=0.6, alignment=0.1, teleport=True) for boid in flock: push() translate(boid.x, boid.y) scale(0.5 + boid.depth) rotate(boid.heading) arrow(0, 0, 15) pop() canvas.size = 600, 300 def main(canvas): canvas.run(draw) Update2: Line 139 [pyglet/lib.py] sys.platform is not win32... there was the error. Fixed it by just using the line: from pyglet.gl.lib_wgl import link_GL, link_GLU, link_WGL Now the following Error: 'module' object has no attribute '_getframe' Kind of a pain to fix it. Updating with results... Update3: Fixed by adding following line right after first line in C#-Code: setup.Options["Frames"] = true; Current Problem: No module named unicodedata, but in Python26/DLLs is only a *.pyd file`. So.. how do i implement it now?!

  • Assign binding path at runtime in WPF DataTemplate

    - by Abiel
    I am writing a WPF program in C# in which I have a ListView for which the columns will be populated at runtime. I would like to use a custom DataTemplate for the GridViewColumn objects in the ListView. In the examples I have seen where the number of columns is fixed in advance, a custom DataTemplate is often created using something like the XAML below. <DataTemplate x:Key="someKey"> <TextBlock Text="{Binding Path=FirstName}" /> </DataTemplate> This DataTemplate could also later be assigned to GridViewColumn.CellTemplate in the code-behind by calling FindResource("someKey"). However, this alone is of no use to me, because in this example the Path element is fixed to FirstName. Really I need something where I can set the Path in code. It is my impression that something along these lines may be possible if XamlReader is used, but I'm not sure how in practice I would do this. Any solutions are greatly appreciated.

  • Microphone audio streaming from Cocoa mac app to iPhone

    - by Benzamin
    Hi devs, I'm trying to build a microphone audio streamer to iPhone. The server software will be a mac desktop app and the client will be iPhone, and they are connected via tcp port. I've successfully connected the mac app and iPhone, and tried to send a fixed test.m4a audio file first. But at the iPhone i grabbed the data well, when tried to play it i used AVAudioPlayer and its returning OSStatus error. I played around with the audio queue service but its very tricky and i only got some example for fixed length audio playing like http://cocoawithlove.com/2009/06/revisiting-old-post-streaming-and.html Now i need help on two things, how can i continuously grab audio data from Mac desktop microphone? And then after grabbing the data how i can play this unfixed length audio data in the iPhone. What exactly i need to do? Please please help me on this......

  • gwt rounded panel (standards based widget akin to DecoratorPanel)

    - by brad
    I'm trying to write an app that uses rounded corners for framing the app. I've found a package on google code that has a RoundedLinePanel and it seems to work... kind of. I'm wondering a few things. Is this what people are using for creating divs with round corners in GWT? The release notes say it hasn't changed in almost a year. Also, I can't seem to set a fixed height of this div (setHeight sets it on the wrapper div, not the inner one). so it's not useful to me as I have a fixed height app. Finally, if anyone can suggest a better mechanism for creating rounded corner divs in GWT I'm all ears.

  • How to Determine the Size of MSADO Command Parameters

    - by Adam
    I am new to MS ADO and trying to understand how to set the size on command parameters as created by the command.CreateParameter (Name, Type, Direction, Size, Value) The documentation says the following: Size Optional. A Long value that specifies the maximum length for the parameter value in characters or bytes. ... If you specify a variable-length data type in the Type argument, you must either pass a Size argument or set the Size property of the Parameter object before appending it to the Parameters collection; otherwise, an error occurs. 1.) What should one pass for fixed-size parameters? Is it a "don't care"? I was a bit confused by the example found here, in which they set size to 3 for an adInteger parameter with Value set to a variant of type VT_I2 pPrmByRoyalty->Type = adInteger; pPrmByRoyalty->Size = 3; pPrmByRoyalty->Direction = adParamInput; pPrmByRoyalty->Value = vtroyal; VT_I2 implies two bytes. A tagVARIANT struct is 16 bytes. How did they land on three? I see that the enum value for adInteger happens to be three, but I suspect that is just a coincidence. So it's a bit confusing what to pass for fixed-size parameters. The team I'm working with has always passed sizeof(int) for adInteger, and it seems to work. Is that correct? Now, for "variable-length" parameters: we are instructed by the documentation to pass "the maximum length .. in characters or bytes". 2.) For adVarChar, is it sufficient to pass the max width as defined in the database? 3.) What about the Wide types (e.g. adVarWChar)? Is it characters or bytes? 4.) How about adVariant, which could contain fixed- or variable-length data? 5.) Do arrays ever come into play here? (we don't pass them as parameters, just curious) Any references or personal insights are welcome.

  • Converting C# void* to byte[]

    - by Yurik
    In C#, I need to write T[] to a stream, ideally without any additional buffers. I have a dynamic code that converts T[] (where T is a no-objects struct) to a void* and fixes it in memory, and that works great. When the stream was a file, I could use native Windows API to pass the void * directly, but now I need to write to a generic Stream object that takes byte[]. Can anyone suggest a hack way to create a dummy array object which does not actually have any heap allocations, but rather points to an already existing (and fixed) heap location. This is the pseudo-code that I need: void Write(Stream stream, T[] buffer) { fixed( void* ptr = &buffer ) // done with dynamic code generation { int typeSize = sizeof(T); // done as well byte[] dummy = (byte[]) ptr; // <-- how do I create this fake array? stream.Write( dummy, 0, buffer.Length*typeSize ); } }

  • Incorrectly formatted html inconsistencies between DOM and what's displayed in firefox plugin

    - by deadalnix
    I'm currently developing a firefox plugin. This plugin has to handle very crappy website that is really incorrectly formatted. I cannot modify these websites, so I have to handle them. I reduced the bug I'm facing to a short sample of html (if this appellation is appropriate for an horror like this) : <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <title>Some title.</title> <!-- Oh fuck yes ! --> <div style="visability:hidden;"> <a href="//example.com"> </a> </div> <!-- If meta are reduced, then the bug disapears ! --> <meta name="description" content="Homepage of Company.com, Company's corporate Web site" /> <meta name="keywords" content="Company, Company & Co., Inc., blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla" /> <meta http-equiv="Content-Language" content="en-US" /> <meta http-equiv="content-type" content="text/html; charset=utf-8"/> </head> <body class="homePage"> <div class="globalWrapper"><a href="/page.html">My gorgeous link !</a></div> </body> </html> When opening the webpage, « My gorgeous link ! » if displayed and clickable. However, when I'm exploring the DOM with Javascript into my plugin, everything behaves (DOM exploration and innerHTML property) like the code was this one : <html> <head> <title>Some title.</title> <!-- Oh fuck yes ! --> </head><body><div style="visability:hidden;"> <a href="//example.com"> </a> </div> <!-- If meta are reduced, then the bug disapears ! --> <meta name="description" content="Homepage of Company.com, Company's corporate Web site"> <meta name="keywords" content="Company, Company &amp; Co., Inc., blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla, blablabla"> <meta http-equiv="Content-Language" content="en-US"> </body> </html> So, when exploring the DOM within the plugin, the document is somehow fixed by firefox. But this fixed DOM is inconsistent with what is in the webpage. Thus, my plugin doesn't behave as expected. I'm really puzzled with that issue. The problem exists in both firefox 3.6 and firefox 4 (didn't tested firefox 5 yet). For example, reducing the meta, will fix the issue. Where does this discrepancy come from ? How can I handle it ? EDIT: With the answer I get, I think I should be a little more precise. I do know what firefow is doing when modifying the webpage in the second code snippet. The problem is the following one : « In the fixed DOM that I get into my plugin, the gorgeous link doesn't appear anywhere, but this link is actually visible on the webpage, and works. So the DOM I'm manipulating, and the DOM in the webpage are different - they are fixed in a different manner. » . So where does the difference come in the fixing behaviour, and how can I handle that, or, in other terms, how can I be aware, in my plugin, of the existance of the gorgeous link ?

  • Do you still limit line length in code?

    - by Noldorin
    This is a matter on which I would like to gauge the opinion of the community: Do you still limit the length of lines of code to a fixed maximum? This was certainly a convention of the past for many languages; one would typically cap the number of characters per line to a value such as 80 (and more recnetly 100 or 120 I believe). As far as I understand, the primary reasons for limiting line length are: Readability - You don't have to scroll over horizontally when you want to see the end of some lines. Printing - Admittedly (at least in my experience), most code that you are working on does not get printed out on paper, but by limiting the number of characters you can insure that formatting doesn't get messed up when printed. Past editors (?) - Not sure about this one, but I suspect that at some point in the distant past of programming, (at least some) text editors may have been based on a fixed-width buffer. I'm sure there are points that I am still missing out, so feel free to add to these... Now, when I tend to observe C or C# code nowadays, I often see a number of different styles, the main ones being: Line length capped to 80, 100, or even 120 characters. As far as I understand, 80 is the traditional length, but the longer ones of 100 and 120 have appeared because of the widespread use of high resolutions and widescreen monitors nowadays. No line length capping at all. This tends to be pretty horrible to read, and I don't see it too often, though it's certainly not too rare either. Inconsistent capping of line length. The length of some lines are limited to a fixed maximum (or even a maximum that changes depending on the file/location in code), while others (possibly comments) are not at all. My personal preference here (at least recently) has been to cap the line length to 100 in the Visual Studio editor. This means that in a decently sized window (on a non-widescreen monitor), the ends of lines are still fully visible. I can however see a few disadvantages in this, especially when you end up writing code that's indented 3 or 4 levels and then having to include a long string literal - though I often take this as a sign to refactor my code! In particular, I am curious what the C and C# coders (or anyone who uses Visual Studio for that matter) think about this point, though I would be interested in hearing anyone's thoughts on the subject. Edit Thanks for the all answers - I appreciate the variety of opinions here, all presenting sound reasons. Consensus does seem to be tipping in the direction of always (or almost always) limit the line length. Interestingly, it seems to be in various coding standards to limit the line length. Judging by some of the answers, both the Python and Google CPP guidelines set the limit at 80 chars. I haven't seen anything similar regarding C# or VB.NET, but I would be curious to see if there are ones anywhere.

  • How can I stop my "headerSticky" and "content" divs from overlapping?

    - by danielle
    I'm making a page that has three main components: a "headerSticky" header div, "sidenav" left navigation div, and "content" div. The side navigation is fixed and does not move; but the content div should be scrollable on its own. However, the top of the content div is always overlapped by the header div. Here is the CSS for the header: #headerSticky{ float:top; position:fixed; padding:6px; width: 100%;} and the content div: #content { padding-top: 100px; float:right; overflow: auto; height: 90%; width: 840px; padding: 0 20px 20px;} Any help would be appreciated. Thank you!

  • How to leverage concurrency checking with EF 4.0 POCO Self Tracking Entities in a N-Tier scenario?

    - by Mark Lindell
    I'm using VS1010RC with the POCO self tracking T4 templates. In my WCF update service method I am using something similar to the following: using (var context = new MyContext()) { context.MyObjects.ApplyChanges(myObject); context.SaveChanges(); } This works fine until I set ConcurrencyMode=Fixed on the entity and then I get an exception. It appears as if the context does not know about the previous values as the SQL statement is using the changed entities value in the WHERE clause. What is the correct approach when using ConcurrencyMode=Fixed?

  • Perl "Day too big" - root cause

    - by azp74
    I have been helping someone debug some code where the error message was "Day too big". I know that this springs from localtime and the Y2038 bug (most google results appear to be people dealing with cookies expiring well into the future). We appear to have 'fixed' the problem by using time to get the current date. However, given that none of our original dates should have hit the 2038 issue I'm sceptical that we've actually fixed the problem ... Are there other instances that anyone knows of where one would hit "day too big"?
