• IDENTITY_INSERT is set to off error

  - by kingrichard2005

  I have a MVC web application with a table in the model that I would like to add to. I have the primary key set along with the other data fields, but every time I try to add to the table, I get the following error: "Cannot insert explicit value for identity column in table 'TABLE_NAME' when IDENTITY_INSERT is set to OFF." I'm not sure why this problem is coming up, I have the primary key set as the identity and it is also set to auto increment in the Visual Studio table designer. Is there any way I can adjust the IDENTITY_INSERT parameter in the table designer in Visual Studio?? Or is there some other issue that might be causing this.

• Solution: Android INSTALL_FAILED_INSUFFICIENT_STORAGE error.

  - by Andrew Smith

  The INSTALL_FAILED_INSUFFICIENT_STORAGE error is the bane of every Android developer's life. It happens regardless of app size, or how much storage is available. Rebooting the target device fixes the problem briefly, but it soon comes back. There are hundreds (if not thousands) of message board posts from people asking why the problem occurs, but the folks at Google are frustratingly silent on the issue. There is a simple workaround. If your test device is running Android 2.2 or later then add the android:installLocation attribute to your application's manifest file, with the value "preferExternal". This will force the app to be installed on the device's external storage, such as a phone's SD card. For example: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.andrewsmith.android.darkness" android:installLocation="preferExternal" This is more of a band-aid than a fix, and it may not be ideal if you want your finished app to install on the device's internal memory. But it will at least make the development process a lot less frustrating.

• Expression.Call() to String.Equals() throws error

  - by Sam

  The following code: var constant = Expression.Constant("find me", typeof(string)); // memberExpression evaluates to a string var predicate = Expression.Call(memberExpression, "Equals", null, constant); is throwing the error More than one method 'Equals' on type 'System.String' is compatible with the supplied arguments. I'm guessing that's because there's Equals(Object) and Equals(String) - is there any way for me to specify which method I mean to use via the overload of Expression.Call() that takes an instance method name as a string? Or do I have to make a special case for calls to Equals() to take a MethodInfo instead?

• Fully custom validation error message with Rails

  - by marcgg

  Using Rails I'm trying to get an error message like "The song field can't be empty" on save. Doing the following: validates_presence_of :song_rep_xyz, :message => "can't be empty" ... only displays "Song Rep XYW can't be empty", which is not good because the title of the field is not user friendly. How can I change the title of the field itself ? I could change the actual name of the field in the database, but I have multiple "song" fields and I do need to have specific field names. I don't want to hack around rails' validation process and I feel there should be a way of fixing that.

• Jquery .Ajax error when trying to POST data in ASP.NET MVC

  - by GB

  I am unable to access an action in my controller using .ajax. The code works on my development machine but as soon as I place it on the server it gives the error 401 Unauthorized. Here is a snippet of the code in the .aspx file... var encoded = $.toJSON(courseItem); $.ajax({ url: '<%= Url.Action("ViewCourseByID", "Home") %>/', type: "POST", dataType: 'json', data: encoded, //contentType: "application/json; charset=utf-8", success: function(result) { Update: The only time this doesn't work is when I pass json data to the Ajax call, it works fine with HTML data.

• Django "Page not found" error page shows only one of two expected urls

  - by Frank V

  I'm working with Django, admittedly for the first time doing anything real. The URL config looks like the following: urlpatterns = patterns('my_site.core_prototype.views', (r'^newpost/$', 'newPost'), (r'^$', 'NewPostAndDisplayList'), # capture nothing... #more here... - perhaps the perma-links? ) This is in an app's url.py which is loaded from the project's url.py via: urlpatterns = patterns('', # only app for now. (r'^$', include('my_site.core_prototype.urls')), ) The problem is, when I receive a 404 attempting to utilize newpost, the error page only shows the ^$ -- it seems to ignore the newpost pattern... I'm sure the solution is probably stupid-simple but right now I'm missing it. Can someone help get me on the right track...

• CakePHP - radio button not showing error message

  - by teepusink

  Hi, I'm unable to get the error message to show up when creating a radio form using the CakePHP form helper. This is what I have now. $options=array('active'=>'Active','inactive'=>'Inactive'); echo $form->input('Status', array( 'type' => 'radio', 'id' => 'EntryStatus', 'name' => 'data[Entry][status]', 'options' => $options )); What am I missing? I'm using CakePHP 1.2.7 and this is what I have in the validation 'status' = array( 'notempty' = array( 'rule' = 'notempty', 'required' = true, 'message' = 'yo' ) ) Tried the answer from http://stackoverflow.com/questions/1388823/form-helper-for-creating-radio-button-in-cakephp and it's giving me a select option form instead. Thanks, Tee

• error: polymorphic expression with default arguments

  - by 0__

  This following bugs me: trait Foo[ A ] class Bar[ A ]( set: Set[ Foo[ A ]] = Set.empty ) This yields <console>:8: error: polymorphic expression cannot be instantiated to expected type; found : [A]scala.collection.immutable.Set[A] required: Set[Foo[?]] class Bar[ A ]( set: Set[ Foo[ A ]] = Set.empty ) ^ It is quite annoying that I have to repeat the type parameter in Set.empty. Why does the type inference fail with this default argument? The following works: class Bar[ A ]( set: Set[ Foo[ A ]] = { Set.empty: Set[ Foo[ A ]]}) Please note that this has nothing to do with Set in particular: case class Hallo[ A ]() class Bar[ A ]( hallo: Hallo[ A ] = Hallo.apply ) // nope Strangely not only this works: class Bar[ A ]( hallo: Hallo[ A ] = Hallo.apply[ A ]) ...but also this: class Bar[ A ]( hallo: Hallo[ A ] = Hallo() ) // ???

• Error in Decompression?

  - by user595606

  I am writing a crawler for a website. Its response is gzip encoded. I am not able to parse correctly a particular field, though the decompression is successful. I am also using htmlagilitypack to parse it, the parsed value of the field is only a part of the original value as an example : I am getting only /wEWAwKc04vTCQKb86mzBwKln/PuCg== whereas the firebug shows the actual value as much longer: /wEWBgKj7IuJCgKb86mzBwKln/PuCgLT250qAtC0+8cMAvimiNYD what does the '==' at the end means? I am assuming it that its a error on decompressors behalf?

• Is this an UITableView -beginUpdates documentation error?

  - by mystify

  I can't wrap my head around what they tried to say here in the docs for -beginUpdate: Call this method if you want subsequent insertions, deletion, and selection operations (for example, cellForRowAtIndexPath: and indexPathsForVisibleRows) to be animated simultaneously. Let's see... cellForRowAtIndexPath: and indexPathsForVisibleRows are both GETTER methods. They do not update anything and do not change anything. So why should I call -beginUpdates before calling these? And what's animated regarding these? Well, nothing, huh? Just want to make sure this is really an error in the docs and I didn't miss something.

• MySQL parameter resource error

  - by Derek

  Here is my error: Warning: mysql_query() expects parameter 2 to be resource, null given... This refers to line 23 of my code which is: $result = mysql_query($sql, $connection) My entire query code looks like this: $query = "SELECT * from users WHERE userid='".intval( $_SESSION['SESS_USERID'] )."'"; $result = mysql_query($query, $connection) or die ("Couldn't perform query $query <br />".mysql_error()); $row = mysql_fetch_array($result); I don't have a clue what has happpened here. All I wanted to do was to have the value of the users 'fullname' displayed in the header section of my web page. So I am outputting this code immediately after to try and achieve this: echo 'Hello '; echo $row['fullname']; Before this change, I had it working perfectly, where the session variable of fullname was echoed $_SESSION['SESS_NAME']. However, because my user can update their information (including their name), I wanted the name displayed in the header to be updated accordingly, and not displaying the session value.

• Visual studio deployment project error when writing to registry

  - by Rekreativc

  Hello I have a setup for an application that was recently converted to be a framework 4.0 project (don't know if it's relevant). The setup has to write to registry (Local Machine) and until now this has always worked perfectly, however now it fails to write to registry on a clean machine (running Windows 7, 64 bit). The setup does not fail, does not show a warning of any kind, however it does not write to the registry (I even set AlwaysCreate property to true on every key, just in case) which of course causes the application to terminate on startup. What could be the cause of this? I have never encountered such an error before. Edit: I have tried running the installer as administrator, didn't change anything.

• Catching an error for a child resource in Ruby on Rails

  - by randombits

  What is the best way to add errors to render if a child resource is really what's having issues and not the parent resource? In english what I mean is the following.. imagine the following code: @foo = Foo.new foochild = Foochild.new // break foochild somehow @foo << foochild @foo.save now when I do: format.xml { render :xml => @foo.errors } I don't get anything about how foochild broke, meaning the error message is useless to the user. How does one go about fixing this?
