  • Insert record into mysql db with Entity Framework

    - by sanfra1983
    Hi, the problem is that it will insert a new record in a mysql table, I have already done the mapping of the mysql db and I have already done tests returning data and everything works. Now I read from a file, where there are queries written, I have them run me back and the result of true or false based on the final outcome of single query written to the file. Txt; I did this: using (var w = new demotestEntities ()) ( foreach (var l listaqueri) ( var p = we.CreateQuery <category> (l); we.SaveChanges (); result = true; ) ) but it does not work, I sense that it returns no errors, but neither the result given written in the query. txt file is as follows: INSERT INTO category (id, name) VALUES (null, 'test2') anyone can help me?

  • error handling in asp.net

    - by user98454
    Hi How can i pass the different types of errors from Data access layer to presentation layer? suppose if we take the northwind database scenario I want to delete the customer, so i selected one customer in ui and clicked the "delete" button.It internally calls the "delete" in data access layer. The prerequisite for deleting the customer is that the customer doesn't have any orders.So in data access layer we wil check whether that customer has any orders.If the customer has orders how can we pass the message from dal to presentation layer that the customer has orders and we don't delete. Am i doing right?is there any other ways to deal with this type? Thanks in advance

  • SQL returns non-array value in PHP

    - by DeadMG
    $request = 'SELECT * FROM flight WHERE Id = \''.$_SESSION['LFLightRadio'].'\''; $data = mysql_fetch_array(mysql_query($request, $SQL)); echo '<table class="table">'; foreach($data as $key => $value) { echo '<th class="head" align="center" height="19">'.$key.'</th>'; } echo '<tr>'; foreach($data as $key => $value) { echo '<td class="cell" align="center" height="19">'.$value.'</td>'; } echo '</tr></table>'; I know that the LFlightRadio value is set, and is a value returned by the Id value of a previously returned row from the flight database. So within "flight", a record definitely exists with this Id. But, this still gives me a non-array result, so that when I try to use foreach on it, it errors out. Suggestions?

  • Sorting top votes in a timeframe using "Vote it up" and wordpress

    - by Mathias
    I'm building a digg-like voting site for christmas greetings. I'm using wordpress and the "Vote it up" plugin. I am having alot of troubles being able to sort the vop votes within a timeframe. You can see what I mean on this site; http://wordtaps.com/ Look at the timeframe on the top right, that's exactly what I want. The site also uses the "Vote it up" plugin along with wordpress. There are a couple of fuctions on the "vote it up" plugin page which I assume would work, but I just keep on getting errors when I try to use them as I know very little php. My site is; www.dinjulehilsen.no (it's on norwegian) All help is greatly appreciated, thank you :)

  • ADO.NET - DataRead Error

    - by user560706
    Hi, I am trying to display data from a column in my database onto my rich textbox, but I am getting mixed up between DataSet and DataReader - I know the majority of the code below is correct, I just get two lines containing errors, and I'm not sure why: // Create a connection string string ConnectionString = ("Provider=Microsoft.ACE.OLEDB.12.0;Data Source= C:\\Documents and Settings\\Harley\\Desktop\\Test.accdb"); string SQL = "SELECT * FROM Paragraph"; // create a connection object SqlConnection conn = new SqlConnection(ConnectionString); // Create a command object SqlCommand cmd = new SqlCommand(SQL, conn); conn.Open(); DataTable dt = new DataTable(); da.Fill(dt); //ERROR // Call ExecuteReader to return a DataReader SqlDataReader reader = cmd.ExecuteReader(); foreach(DataRow reader in dsRtn) //ERROR { richTextBox = richTextBox.Text + reader[0].ToString(); } //Release resources reader.Close(); conn.Close(); }

  • Why does OSX document atoi/atof as not being threadsafe?

    - by Larry Gritz
    I understand that strtol and strtof are preferred to atoi/atof, since the former detect errors, and also strtol is much more flexible than atoi when it comes to non-base-10. But I'm still curious about something: 'man atoi' (or atof) on OS X (though not on Linux!) mentions that atoi/atof are not threadsafe. I frankly have a hard time imagining a possible implementation of atoi or atof that would not be threadsafe. Does anybody know why the man page says this? Are these functions actually unsafe on OS X or any other platform? And if they are, why on earth wouldn't the library just define atoi in terms of strtol, and therefore be safe?

Here goes some of them, 1)Just try to install it in VisualStudio, you will got enough for the day. 2)After you installed it as a separate qt(without embedding it inside visual studio).Open a c++ file in qt, = then you won't get any option to compile it. 3)Create a empty qt4 project like below #include<iostream> using namespace std; int main(int a,char * argv[]) { } Then build it, you will get a error like this C:\qt-greenhouse\Trolltech\Code_less_create_more\Trolltech\Code_less_create_more\Troll\4.6\qt\src\winmain/qtmain_win.cpp:131: undefined reference to `qMain(int, char**)' Can anybody clear any of these problems to me.

But, when I try to create from testcase, I am getting the following error: java.lang.NoClassDefFoundError: org/apache/poi/hssf/usermodel/HSSFWorkbook I have added required jar file into lib folder and added to build-path. Why its working from normal java program, but not working from WindowTester generated testcase. Could anyone help me.

  • Input string was not in correct format.

    - by jawahar-sync
    Hi Experts, I had a Ribbon like custom control. I created an application using this control. These applications work fine until I change the system number format. They crashes if I change the system number format like below: Current Format = English (United State) Decimal symbol = ',' Digit group symbol = '.' When I run applications, they throw an exception "Input string not in Correct format". . Some other applications specify the Exception's message = "Input string '0,2,0,2' was not a correct format", so I think in Wpf ES's xaml files, we may declare some properties i.e Padding, Margin like "0,2,0,2" = that will cause errors with the system number format above. I have note that this error only occurs in Windows Vista, it does not occurs on Windows XP. I do not know why? I have also look at this link, But it not helps for Vista. http://support.microsoft.com/kb/968227/en-us

    - by Hazar
    I have a ~300.000 row table; which includes technical terms; queried using PHP and MySQL + FULLTEXT indexes. But when I searching a wrong typed term; for example "hyperpext"; naturally giving no results. I need to "compansate" little writing errors and getting nearest record from database. How I can accomplish such feaure? I know (actually, learned today) about Levenshtein distance, Soundex and Metaphone algorithms but currently not having a solid idea to implement this to querying against database. Best regards. (Sorry about my poor English, I'm trying to do my best)

  • I'm an idiot/blind and I can't find why I'm getting a list index error. Care to take a look at these 20 or so lines?

    - by Meff
    Basically it's supposed to take a set of coordinates and return a list of coordinates of it's neighbors. However, when it hits here:if result[i][0] < 0 or result[i][0] >= board.dimensions: result.pop(i) when i is 2, it gives me an out of index error. I can manage to have it print result[2][0] but at the if statement it throws the errors. I have no clue how this is happening and if anyone could shed any light on this problem I'd be forever in debt. def neighborGen(row,col,board): """ returns lists of coords of neighbors, in order of up, down, left, right """ result = [] result.append([row-1 , col]) result.append([row+1 , col]) result.append([row , col-1]) result.append([row , col+1]) #prune off invalid neighbors (such as (0,-1), etc etc) for i in range(len(result)): if result[i][0] < 0 or result[i][0] >= board.dimensions: result.pop(i) if result[i][1] < 0 or result[i][1] >= board.dimensions: result.pop(i) return result

  • Putting $$s in the middle of an `equation` environment: why doesn't Latex complain?

    - by Charles Stewart
    I was surprised that the Latex code from a recent question didn't throw up any errors, and even more surprised on further investigation, that Crowley's explanation seems to be true. My intuition about the \begin{equation} ... \end{equation} code is clearly off, what's really going on? Consider this, slightly adapted code: \begin{equation} 1: e^{i\pi}+1=0 $$ 2: B\"ob $$ 3: e=mc^2 \end{equation} This seems to prove that Crowley's explanation of such code, namely that "What that code says to LaTeX is begin equation, end it, begin it again, typeset definition of tangens and end the equation" is right: lines 1&3 can only be typeset in maths mode, line 2 only in text mode. Shouldn't Latex see that the \end{equation} is ending a display math that wasn't started by the \begin{equation}?

  • How does R treat positional arguments

    - by inspectorG4dget
    I'm a python guy and very new to R (so far, all I've done is copy-paste code and screen-shot the resulting, graph). I would now like to actually learn the language so that I can draw useful plots (right now, I am trying to plot this). In attempting my first plot, I came across this function call: sets_options("universe", seq(from = 0, to = 25, by = 0.1)) Now, I would like to know if I can achieve the same result by calling sets_options("universe", seq(0, 25, 0.1)) The help page for seq doesn't speak to this specifically (or I'm not reading it correctly), so I was hoping someone could shed some light on how R handles positional arguments I tried calling the function that way in R and it worked (no syntax errors, etc), but I don't know how to test the output of that function, so I'm forced to ask here

  • How to issue SQL Server lock hints in WCF Entity Framework?

    - by TMN
    I'm just learning the WCF entity framework (and .net in general), and I'm running into a problem specifying lock hints in an embedded SQL query. I'm trying to specify a query that has lock hints in it (e.g., "SELECT * FROM xyz WITH(XLOCK, ROWLOCK)") and I keep getting errors from the runtime that the query syntax is not valid. The query works if I enter it directly into SQL Server. Is there some special syntax for lock hints when creating IQueryable result sets, or do I have to somehow mess with the transaction isolation level (probably not possible, as I need to specify different lock hints on a subquery within the main query).

  • Hibernate deletion issue

    - by muffytyrone
    I'm trying to write a Java app that imports a data file. The process is as follows Create Transaction Delete all rows from datatable Load data file into datatable Commit OR Rollback if any errors were encountered. The data loaded in step 3 is mostly the same as the data deleted in step3. The deletion is performed using the following DetachedCriteria criteria = DetachedCriteria.forClass(myObject.class); List<myObject> myObjects = hibernateTemplate.findByCriteria(criteria); hibernateTemplate.deleteAll(myObjects); When I then load the datafile, i get the following exception nested exception is org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: The whole process needs to take place in transaction. And I don't really want to have to compare the import file / data table and then perform an insert/update/delete to get them into sync. Any help would be appreciated.

  • Ninject caching an injected DataContext? Lifecycle Management?

    - by awrigley
    I had a series of very bizarre errors being thrown in my repositories. Row not found or changed, 1 of 2 updates failed... Nothing made sense. It was as if my DataContext instance was being cached... Nothing made sense and I was considering a career move. I then noticed that the DataContext instance was passed in using dependency injection, using Ninject (this is the first time I have used DI...). I ripped out the Dependency Injection, and all went back to normal. Instantly. So dependency injection was the issue, but I still don't know why. I am speculating that Ninject was caching the injected DataContext. Is this correct? Is there a way of configuring the lifecycle management of injected parameters? If so, what would be the best configuration to use to have the DataContext behave like a normal DataContext, ie, no caching across requests?

  • Mod_rewrite works on local, not on remote, version?

    - by TylerT
    I have this site. Let's call it htp://www.mysite.com I have a rewrite rule to change htp://www.mysite.com/?q=words%20etc/0/10 into http://www.mysite.com/words%20etc/0/10 (or http://www.mysite.com//0/10 or http://www.mysite.com/0/10) .htaccess:ErrorDocument 404 htp://www.mysite.com/404.html options +FollowSymlinks rewriteEngine on rewriteCond %{REQUEST_URI} !-f rewriteCond %{REQUEST_URI} !-d rewriteCond %{REQUEST_URI} !index\.php rewriteRule ^/?([^/]+?)?/?([0-9]+?)/([0-9]+?)$ index.php/%{THE_REQUEST} [NC] Now, this works on my local apache 2.2.11 server, no errors. However on my host's apache 1.3.41 server, I get the following error: [Sat Mar 5 21:42:14 2011] [alert] [client [ip]] /home/_/public_html/mysite.com/.htaccess: RewriteRule: cannot compile regular expression '^/?([^/]+?)?/?([0-9]+?)/([0-9]+?)$'\n I imagine it's something quirky about the apache version as other sites on this host use mod_rewrite without a hitch. I've tried removing the +followSymlinks line, even the rewrite engine line. I haven't tried removing the conditions cause I don't think I should have to, I'm probably wrong.

  • Session sharing

    - by GeoXYZ
    Hello, i have a problem with Session sharing... I have a single web application hosted on a server. I created in IIS 2 different domains for the same application (thus each pointing to same physical path). The first domain is used as main interface, and the second domain is used to change settings (kind of like an admin). If the user logs in (login information is stored in session) the first domain, and then goes to the second one, he is also logged in there, which is OK. but when i try to change something in the session (like email address) from the second domain, the data is changed OK but only in the first domain; in the second one i still have the old data... also what i've noticed is that when redirecting from first domain to second domain, every postback control posts back to the first domain even though i am on the second one - this causes encryption errors with the viewstate... If anyone has any ideas, i would appreciate it... Thank you.

  • Why does System.Threading.Timer callback successfully update UI?

    - by Geo P
    I have several System.Threading.Timers on my form application with callbacks that update the UI...successfully - i.e. without throwing errors. I had built these earlier, before I knew that UI should not be updated on any thread other than the UI thread. Now I am confused as to why it does not throw cross-thread exceptions when I am updating UI on these separate threading.timer threads? I will be changing these callbacks so that the UI updates are invoked on UI thread, but I am curious as to why this works. Edit: My application is a WinForms Application.

  • How to make flyspell bypass some words by context?

    - by manu
    Hi, I use Emacs for writing most of my writings. I write using reStructuredText, and then transform them to LaTeX after some preprocessing since I write my citations á-la LaTeX. This is an excerpt of one of my texts (in Spanish): En \cite[pp.~XXVIII--XXIX]{Crnkovic2002} se brindan algunos riesgos que se pueden asumir con el desarrollo basado en componentes, los This text is processed by some custom scripts that deals with the \cite part so rst2latex can do its job. When I activate flyspell-mode it signals most of the citation keys as spelling errors. How can I tell flyspell not to spellcheck things within \cite commands. Furthermore, how can I combine rst-mode and flyspell, so that rst-mode would keep flyspell from spellchecking the following? reST comments reST code literal reST directive parameters and arguments reST raw directive contents Any ideas?
