• ASP.NET MVC- Bizarre problem - suddennly lost all LINQTO SQL data context objects

  - by MikeD

  I was making an edit to a long existing project. Specifically I added some fields to a table and had to delete the table from the LINQTOSQL designer and re-add it. doesn't Also had to do the same for a view. Mode some other code changes and went to build . Now my project won't build because it can't resolve any of the data context objects (all tables and views) in my code. I don't know what I did or how this happeened. I have many tables and views in the project's L2S data context so I don't wont to try and do over. Please any suggestions on how to resolve this problem are greatly appreciated. Desparate! The error messages I am getting are the familiar The type or namespace name 'equipment' could not be found (are you missing a using directive or an assembly reference?)

• DragDrop registration did not succeed in Setup Project

  - by rodnower

  Hello, we have some installation project in Visual Studio solution (Other project types - Setup and deployment - Setup project). This project have other library type project with Installation class named InstallationCore like project output.

• Convert data retrieved from MySQL database into JSON object using Python/Django

  - by rohanbk

  I have a MySQL database called People which contains the following schema <id,name,foodchoice1,foodchoice2>. The database contains a list of people and the two choices of food they wish to have at a party (for example). I want to create some kind of Python web-service that will output a JSON object. An example of output should be like: { "guestlist": [ {"id":1,"name":"Bob","choice1":"chicken","choice2":"pasta"},{"id":2,"name":"Alice","choice1":"pasta","choice2":"chicken"} ], "partyname": "My awesome party", "day": "1", "month": "June", "2010": "null" } Basically every guest is stored into a dictionary 'guestlist' along with their choices of food. At the end of the JSON object is just some additional information that only needs to be mentioned once. The question that I have is regarding the method that I need to utilize to grab the data from my database, and create the JSON object. Do I need to use a standard Model/View structure of Django or can I get away with something that is much simpler since what I need to do is really simple?

• Change UIImagePicker Navigation Bar style to blue

  - by vodkhang

  All of my view has a blue navigation bar but when I want user to choose a photo, the UIImagePicker is black. I tried to set the navigation bar of UIImagePickerController to blue using UIBarStyleDefault but it does not work for me, the color is still black. I tried with other UIBarStyle like UIBarStyleBlack and UIBarStyleOpaque as well but it doesn't change the navigation bar of the picker anyway. Here is my code // Let the user choose a new photo. UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; imagePicker.navigationBar.barStyle = UIBarStyleDefault; [self presentModalViewController:imagePicker animated:YES]; [imagePicker release];

• Using accelerometer to detect iPad lock switch trigger?

  - by DevDevDev

  So for complicated reasons I am managing view rotations myself, and am only implementing UIDeviceOrientationPortrait as the autorotating orientation. Anyway, when one clicks the screen lock on the iPad, the device will rotate to UIDeviceOrientationPortrait, which will cause my code to rotate, which I do not want to happen. For instance of the user is holding the device in "landscape mode", i.e. I have already manually rotated the UI to landscape mode, and he/she clicks the screen lock, it will rotate the UI to portrait mode, even though the user did not move the device at all. So somehow I need a way to differentiate between rotations to portrait mode occuring from the screen lock, and those occuring from device rotation. As such, I would like somehow to use the accelerometer to detect whether or not the device was actually 'rotated' or whether the button was clicked. Thanks!

• concurrency in Java

  - by p1

  1]What is Non-blocking Concurrency and how is it different. 2] I have heard that this is available in Java. Are there any particular scenarios we should use this feature 3] Is there a difference/advantage of using one of these methods for a collection. What are the trade offs class List { private final ArrayList<String> list = new ArrayList<String>(); void add(String newValue) { synchronized (list) { list.add(newValue); } } } OR private final ArrayList<String> list = Collections.synchronizedMap(); The questions are more from a learning/understanding point of view. Thanks for attention.

• What could cause a button on a UIActionSheet to "miss" on touches?

  - by Alex Gosselin

  I have a UIActionSheet as follows: UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:[NSString stringWithFormat: @"Cancel New %@? Changes will be lost.", [creator propertyName]] delegate:self cancelButtonTitle:@"Stay Here" destructiveButtonTitle:@"Discard and Close" otherButtonTitles:@"Save and Close", nil]; [sheet showInView:self.view]; [sheet release]; It creates the action sheet, The buttons display, the Destructive button is on top, cancel button is on the bottom, other button (save and close) shows up in the middle, the top two buttons, (destructive and other) work fine, but the bottom button has a gap, so it is farther down than the other buttons. For some reason though, in order to press the button I need to touch where it would be if there was no gap. Touching the actual button doesn't work. Sorry if this isn't super clear, has anyone encountered something like this? I don't like to whip out the "I found a bug" card too fast, maybe I'm doing something wrong here.

• How to load different XIBs for different device orientations for same viewcontroller?

  - by Jaanus

  The documentation says that if I want to support both portrait and landscape, I basically have two ways of doing that: Set up the viewcontroller's view so that the subviews autoresize correctly and make smaller changes programmatically at runtime If the changes are more substantial, create an alternative landscape interface and push/pop the alternative modal viewcontroller at runtime I would like to present the info where the layout is substantially different, but logic is the same. Ideally, I would load another XIB for the same viewcontroller, but it does not seem to be an option. Sounds like #2 is what I need to do, but my problem with that is that it sounds like it would use the standard modalviewcontroller animations that are nothing like the device rotation animation. (Of course, being the lazywebber that I am, I did not test this hypothesis.) So, how do I load an alternative layout for landscape with the same viewcontroller but different XIB? Should I use the method #2 above and is the rotation animation natural? Or is there some other way?

• PHP variable passed to JasperServer for reports

  - by Ronedog

  Is it possible to pass a variable from php to a report in JasperServer? For example, in my php application I keep the department_id stored in a session variable. I would like to pass the department_id over to my reports running on JasperServer and display the information appropriate for that department. in the iReport I have a query like: "SELECT * FROM employees WHERE department_id = $P{dept_id_from_php}", but I have to build a dropdown select list to pass the dept_id parameter. The end result is I would like the user logged into my PHP application to view the employee information that is related to the department the logged-in-user belongs to. I don't want to pass this over using the querystring because the user could just change the id in the querystring and have access to other departments information. Ideally I would like to only pass that parameter once, then reuse it in all the reports, like a global variable. Is this possible?

• FBML in Rails views using Facebooker

  - by ewakened

  Hi all, I have successfully wired up a Facebook Connect application and everything is working fine. I can sign new users up with Facebook, or I can link existing users with Facebook. No problems there. However, now I am trying to add an Invite page, where a user can see which of their Friends have the application, and then show them a Facebook FMBL Multi Select form to invite friends into it. Here is the documentation for that FBML tag. http://wiki.developers.facebook.com/index.php/Connect/Integrating_an_Invite_Form_into_Your_Website#Creating_a_Full_Multi-friend_Selector_Request_or_Invite However, I cannot get this to work within my Rails view. Do I need to setup something special to use FBML in my Rails views? THIS IS NOT A CANVAS Application, meaning I want people to come to my site and not visit the page through facebook, but I feel like I am missing something. Thank you! Kent

• Reused UIWebView showing previous loaded content for a brief second on iPhone

  - by Roi

  In one of my apps I reuse a webview. Each time the user enters a certain view on reload cached data to the webview using the method - (void)loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)encodingName baseURL:(NSURL *)baseURL and I wait for the callback call - (void) webViewDidFinishLoad:(UIWebView *)webView. In the mean time I hide the webview and show a 'loading' label. Only when I receive webViewDidFinishLoad do I show the webview. Many times what happens is I see the previous data that was loaded to the webview for a brief second before the new data I loaded kicks in. I already added a delay of 0.2 seconds before showing the webview but it didn't help. Instead of solving this by adding more time to the delay does anyone know how to solve this issue or maybe clear old data from a webview without release and allocating it every time?

• How do I use Zend Cache on this particular problem

  - by davykiash

  I have an action that renders two different view scripts based on whether the user is logged in or not. class IndexController extends Zend_Controller_Action { .... public function indexAction() { $auth = Zend_Auth::getInstance(); if($auth->hasIdentity()) { $this->render('indexregistered'); return; } else { $this->render('indexpublic'); return; } } .... } I have seen quite some useful examples on how to use the Zend Cache and they seem to be based on the fact that the action renders one particular script. What am really looking at is the best approach to cache the the indexpublic script does get quite some hits and I would live to avoid the Zend MVC overhead if possible.

• iPad title bars. Navbars or toolbars?

  - by Squeegy

  I see a bunch of apps for iPad with really cool title bars. These seem to be a combination of a navigation bar and a toolbar. They usually have a back button and a title as well as men other buttons. And a navbar only supports a left item, a right item and and title view. And the toolbar does not really support back buttons or titles. So how do I implement these rich navbars with many buttons on my UINavigationController driven application?

• Print ms access data in vb.net

  - by user225269

  How do I print the ms access data(.mdb) in vb.net? Here is the code that I'm using to view the data in the form. What I want to do is to be able to print what is currently being viewed. Perhaps automatically save the .pdf file and the pdf viewer installed on the system will open that newly generated pdf file Dim cn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\search.mdb") Dim cmd As OleDbCommand = New OleDbCommand("Select * from GH where NAME= '" & TextBox6.Text & "' ", cn) cn.Open() Dim rdr As OleDbDataReader rdr = cmd.ExecuteReader If rdr.HasRows Then rdr.Read() NoAcc = rdr("NAME") If (TextBox6.Text = NoAcc) Then TextBox1.Text = rdr("IDNUMBER") If (TextBox6.Text = NoAcc) Then TextBox7.Text = rdr("DEPARTMENT") If (TextBox6.Text = NoAcc) Then TextBox8.Text = rdr("COURSE") End If -some sites for beginners regarding this topic would help a lot:)

• Updating a TableView with a WebService and Saving to CoreData

  - by jcady

  I am working on a project where I have a table view that is currently updated via a web request that returns XML. I implemented -(int)numberOfRowsInTableView:(NSTableView*)tv and -(id)tableView:(NSTableView *)tv objectValueForTableColumn:(NSTableColumn*)tableColumn row:(int)row in my XML parsing class, and have the table updated with the data that is pulled down from the server. I want to save the data that is pulled down using Core Data, so that the table can be saved/loaded. Then later on application start when the web request is made, it will only add data that is not already present. (The XML is sorted by release date, so later I will check to see which release dates are not loaded up from the Core Data store, and only load newer entries.) How would I go about implementing this? I am a very new Cocoa developer, but have gone through the entire Hillegass book. Thanks so much.

• Obey the MediaBox/CropBox in PDF when using ghostscript to render a PDF to a png

  - by gordonwatts

  I've been using ghostscript to convert my single figure plots rendered in PDF to png: gswin32c -sDEVICE=png16m -r300x300 -sOutputFile=junk.png -dBATCH -dNOPAUSE Figure_001-a.pdf This works in the sense I get a png out and it contians the plot. But it contains a huge amount of white space as well (an example source image: http://cdsweb.cern.ch/record/1258681/files/Figure_001-a.pdf). If you view it in Acrobat you'll note there is no white space around the plot. If you use the above command line you'll find the plot is only about 1/3 of the space. When doing the same thing with an eps file I run into the same problem. However, there is the command-line parameter -dEPSCrop that one can pass to get the PS rendering engine to pay attention to the BoundingBox. I need the similar argument for rendering PDF's. I was not able to find it in docs (nor even the EPSCrop, actually).

• Overflow on UILabels

  - by jkeesh

  I have a table view that I am customizing and I am adding a UILabel as a subview of the contentView, and I want the number of lines to be relatively consistent. I set the numberOfLines property to be 3 so it can't go more than that, but there are still some that overflow onto the 4th line. If it overflows, I want to add a a trailing ... How can I figure out if it overflows? I've tried truncating at different character counts of my string, but since I am using lineBreakMode = UILineBreakModeWordWrap the number of characters doesn't really predict the number of lines. Is there a way to find out the number of lines your UILabel is using?

• What is a typical scenario for and end-user reports design?

  - by Sebastian

  Hello! I'm wondering what would be the typical scenario for using an end-user report designer. What I'm thinking of is to have a base report with all the columns that I can have, also with a basic view of the report (formatting, order of columns, etc.) and then let the user to change that format and order, take out or add (from the available columns) data to it, etc. Is that a common way to address what is called end-user designer for reports or I'm off track? I know it depends on the user (if it's someone that can handle SQL or not for example), but is it common to have a scenario where the user can build everthing from the sql query to the formatting? Thanks! Sebastian

• Drop shadow coordinate different from iPhone OS 3.2?

  - by Axel

  I'm trying to draw a custom view with a drop shadow. I'm having different results from iPhone OS 3.2. Has the coordinate system changed for CGContextSetShadowWithColor from 3.2? Here is the code I'm using: CGContextRef graphicContext = UIGraphicsGetCurrentContext(); CGColorSpaceRef colorspace = CGColorSpaceCreateDeviceRGB(); CGFloat values1[4] = { 0, 0, 0, 1}; CGColorRef blackColor = CGColorCreate (colorspace, values1); CGContextSetShadowWithColor(graphicContext, CGSizeMake(0, -1), 3, blackColor); CGColorRelease(blackColor); CGFloat values2[4] = { .5, .5, 1, 1}; CGColorRef fillColor = CGColorCreate (colorspace, values2); CGContextSetFillColorWithColor(graphicContext, fillColor); CGColorRelease(fillColor); CGContextFillRect(graphicContext,CGRectMake(40, 40, 100, 100)); Here is how it looks on 3.1 and from 3.2. All my views using drop shadow look different depending on the version of iPhone OS. Am I missing something?
