  • 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?

  • Assign bitset member to char

    - by RedX
    I have some code here that uses bitsets to store many 1 bit values into a char. Basically struct BITS_8 { char _1:1; (...) char _8:1; } Now i was trying to pass one of these bits as a parameter into a function void func(char bit){ if(bit){ // do something }else{ // do something else } // and the call was struct BITS_8 bits; // all bits were set to 0 before bits._7 = 1; bits._8 = 1; func(bits._8); The solution was to single the bit out when calling the function: func(bits._8 & 0x128); But i kept going into //do something because other bits were set. I was wondering if this is the correct behaviour or if my compiler is broken. The compiler is an embedded compiler that produces code for freescale ASICs.

    - by EvanRyan
    I have a winform with two data grids, and multiple text boxes. I want to give the user the option to export this data to a text document in a location of their choice on their drive. I also want the text document to be pre-formatted, and the values from the text boxes and datagrids to be plugged in. Is it possible to pre-format a txt document using StreamWriter? And how to I go about giving the user the option of where to save this exported file?

  • Execute VBA Macro via C# Interop?

    - by Jon Artus
    Hi all, just wondering if anyone could suggest why I might be getting an error? I'm currently trying to execute a macro in a workbook by calling the Application.Run method that the interop exposes. It's currently throwing the following COM Exception: {System.Runtime.InteropServices.COMException (0x800A03EC): Cannot run the macro Macro1'. The macro may not be available in this workbook or all macros may be disabled. I've put the containing workbook in a trusted location, set all of the security settings to their minimum values, and trusted programmatic access to my object model. I'm entirely out of ideas and Google's failed me so far! Has anyone done this, or can you suggest anything which I could try? Many thanks!

  • UIWebView: Media Player Rotates View Controller

    - by RileyE
    I'm encountering an issue while using a webview. My app is currently a portrait application, but when a media player loads in a webview within my app, the user can rotate the player, which rotates my view controller as well. I know I can get a notification for when the player comes up and disappears, but is there a way to prevent it from rotating the controller in the first place? It doesn't seem like anyone has an answer. I have all of the standard "don't rotate unless if I tell you to" methods and plist values, but its still rotating. Its only when I load up a webview and the media player loads over it. If I rotate my device, the media player rotates along with it, which feels natural, but when I go back to the webview view controller, its rotated, which isn't good.

  • [SEO] sitemap.xml What is the precision of the priority field?

    - by Christoph
    Unfortunately the specification does not tell anything about precision. The xml scheme definition states that it is of the type xsd:decimal: <xsd:restriction base="xsd:decimal"> <xsd:minInclusive value="0.0"/> <xsd:maxInclusive value="1.0"/> </xsd:restriction> I have a sitemap generator that uses up to 10 positions after decimal point. Where often only the last few positions differ. These numbers are perfectly right according to the xsd, but yet i found some pages(3,4) that state that only 0.0, 0.1, 0.2, .., 1.0 are valid values. How will the search engines react to such a sitemap? Will some just round the value? I know that it is unlikely that someone can provide an answer to that question, unless he works for that search engine, but i think experiences will also do.

  • Passing javascript form variables into jQuery function not working

    - by Chase
    I am trying to pass some JavaScript variables that I have assigned to form variables into a query string used by a jQuery plug in called fancybox. If I hard code in the string that I want lightbox works great, however I need it to pass some form values in there to make it work as desire. <script type="text/javascript"> $(document).ready(function(){ var item = document.itemFinder.item; var zip = document.itemFinder.zip; var radius = document.itemFinder.radius; var dataString = "item=" + item + "&zip=" + zip + "&radius=" + radius; $("#various3").fancybox({ ajax : { type : "POST", data : dataString}, 'scrolling' : 'auto', 'overlayOpacity' : '0' } ); }); </script> What am I doing wrong?

  • Problem with NHibernate and saving.

    - by Vilx-
    When I do this: Cat x = Session.Load<Cat>(123); x.Name = "fritz"; Session.Flush(); NHibernate detects the change and UPDATEs the DB. But, when I do this: Cat x = new Cat(); Session.Save(x); x.Name = "fritz"; Session.Flush(); I get NULL for name, because that's what was there when I called Session.Save(). Why doesn't NHibernate detect the changes - or better yet, take the values for the INSERT statement at the time of Flush()?

  • Doing a SetLength on an array passed into a proc by reference

    - by csharpdefector
    Hi All, Sure, even I can do this... var testarray : array of string; setlength(testarray, 5); but if I want to get clever and have a procedure into which I pass the array by referance like this I cant do it! procedure DoStuffWithArray(var passedarray : array of string); begin setlength(passedarray, 5); end; compiler says 'incompatible types' on the single line of code in my proc. I can do other stuff on the array like set set element values if i do a setlength before i call the proc, but I cannot do the setlength in my proc, which is what I want to do. Any help much appreciated, thanks all.

  • Mod_rewrite with multiple variables

    - by Andrei
    Hello, I'm using a PHP script that dynamically generates transparent PNGs for use as CSS backgrounds from a query string that takes RGBa and HSLa values. The original script can be found here, I've only added HSLa support. Because background URLs with PHP query strings aren't very pretty, and because it seems to break the IE 6 transparent PNG hack, I thought of using mod_rewrite to allow the script to be called when a .png with this syntax is called : /assets/colors/h[0-360 value]_s[0-100 value]_l[0-100 value]_a[0-100 value].png which would be rewritten to : /assets/colors.php?h=[0-360 value]&s=[0-100 value]&l=[0-100 value]&a=[0-100 value] Here's the issues I'm encountering : passing multiple variables with mod_rewrite using an underscore as a delimiter I know this could be done by passing a single variable and then exploding it in the PHP script, however I would prefer it to be done by Apache. Thanks in advance and if anyone wants my HSLa enabled version of the script just ask. Anyway I recommend you check it out on it's author's website.

  • How can i pass a single additional argument to array_map callback in PHP?

    - by Gremo
    How can i pass a single additional argument to array_map callback? In my example i'd like to pass $smsPattern (as a second argument, after current element in $featureNames) to the function array_map with $getLimit closure: $features = $usage->getSubscription()->getUser()->getRoles(); // SMS regular expression in the form of ROLE_SEND_SMS_X $smsPattern = '/^ROLE_SEND_SMS_(?P<l>\d+)$/i'; // Function to get roles names and X from a role name $getNames = function($r) { return trim($r->getRole()); }; $getLimit = function($name, $pattern) { if(preg_match($pattern, $name, $m)) return $m['l']; }; // Get roles names and their limits ignoring null values with array_filter $featuresNames = array_map($getNames, $features); $smsLimits = array_filter(array_map($getLimit, $featureNames, $smsPattern)); With this code i'm getting a weird warning: Warning: array_map() [function.array-map]: Argument #3 should be an array. Of course di reason is for reusing $getLimit closure with another regular expression like $smsPattern. Thanks.

  • Use JS to add characters into textfield

    - by Thomas
    I want to add a $ symbol before a users entry into a text field without actually submitting the $ when the user clicks submit. Additionally, I need to prohibit the user from entering anything but numerical values in to the text input. I know about the JQuery input mask (http://www.conetrees.com/2009/03/blog/jquery-masked-input-plugin-increase-usability-for-masked-format-input-fields) but this plugin requires you to set the exact number of digits/letters that the user is supposed to enter, which is no good for my current project. Can anyone think of a way to accomplish what I have described above?

  • Emulating a transaction-safe SEQUENCE in MySQL

    - by Michael Pliskin
    We're using MySQL with InnoDB storage engine and transactions a lot, and we've run into a problem: we need a nice way to emulate Oracle's SEQUENCEs in MySQL. The requirements are: - concurrency support - transaction safety - max performance (meaning minimizing locks and deadlocks) We don't care if some of the values won't be used, i.e. gaps in sequence are ok. There is an easy way to archieve that by creating a separate InnoDB table with a counter, however this means it will take part in transaction and will introduce locks and waiting. I am thinking to try a MyISAM table with manual locks, any other ideas or best practices?

  • I need a small parser (jquery) that knows if an input is URL:PORT format

    - by Johua
    You have a user input string from a textbox for example var strInput = $("#txtBox").val(); strInput has some string now. I need to now if it is of this format: IP:PORT Basically a user can input something like this: http://192.168.300.22:20000 1) Frist part (protocol): http:// always needs to be replaced by: https:// 2) Second part (everything until the ":" sign): 192.168.200.22 (or www.google.com) 3) Third part (port): everyhing after ":" (example: 9999, 100000) I step): TAKE THE INPUT var strInput = $("#txtBox").val(); II) step): PARSE THE INPUT III) results): var strProtocol = "https//"; var strIP = parsedIP; var strPORT = parsedPORT; So i need 2 know how to get the values (parsedIP and parsedPORT).

  • Vertically center CSS techniques don't work in Chrome

    - by at.
    I've gone through stackoverflow questions and a whole bunch of articles on vertically centering text like the following: http://blog.themeforest.net/tutorials/vertical-centering-with-css/ None of the techniques seem to work with the latest version of Chrome. Is that just the nature of Chrome? My text just always appears at the top. It seems that whenever I use 50% or 100% as values for CSS's height or top, nothing happens. I just need a single line of text vertically centered. line-height isn't helpful because I want it centered in the middle of the browser window... I don't know how tall the browser window is going to be. UPDATE: The problem is apparently Foundation 4. Once I delete the following everything works as expected: <link href="/assets/foundation_and_overrides.css?body=1" media="screen" rel="stylesheet" /> Any idea on how to make it work with Foundation 4?

  • Is it possible for a Grails Domain to have no 'id'?

    - by firnnauriel
    Is it possible to create a table that has no 'id'? For example, this is my domain: class SnbrActVector { int nid String term double weight static mapping = { version false id generator: 'identity' } static constraints = { } } When I run this SQL statement, it fails: insert into snbr_act_vector values (5, 'term', 0.5) I checked the table and 'id' is already set to autoincrement. I'm thinking that another option is to remove the 'id' itself. Or is there another workaround for this? Please assume that it is not an option to change the givent SQL statement.

  • How can I (both) create a row and accessing that row in the same 'Stored Procedure'?

    - by Richard77
    Hello, I'd like to get the value of the id column for an object just after I've created it. But I don't want to run another query for that. My book for beginner (SQL Server 2008 for Dummies) says that there are 2 tables (inserted and deleted) that hold the last row(s) that have been inserted, updated, or deleted. Unfortunately, only Triggers (says the book) can access those tables. But, if I use triggers, they will go off each time I "insert" a row even when I don't need them that functionality. Can I obtain the same effect with a Store Procedure (without having to run a separate query?) This is what I'm trying to do CREATE PROCEDURE myProcedure DECLARE @OrganizationName @ColumnID OUTPUT AS INSERT INTO Organization (OrganizationName) VALUES (@OrganizationName) SET @ColumnID = (// Please, I need Help here ...) Thanks for helping

  • Python: why does str() on some text from a UTF-8 file give a UnicodeDecodeError?

    - by AP257
    I'm processing a UTF-8 file in Python, and have used simplejson to load it into a dictionary. However, I'm getting a UnicodeDecodeError when I try to turn one of the dictionary values into a string: f = open('my_json.json', 'r') master_dictionary = json.load(f) #some json wrangling, then it fails on this line... mysql_string += " ('" + str(v_dict['code']) Traceback (most recent call last): File "my_file.py", line 25, in <module> str(v_dict['code']) + "'), " UnicodeEncodeError: 'ascii' codec can't encode character u'\xf4' in position 35: ordinal not in range(128) Why is Python even using ASCII? I thought it used UTF-8 by default, and this is a UTF-8 file. What is the problem?

  • Hibernate / MySQL Bulk insert problem

    - by Marty Pitt
    I'm having trouble getting Hibernate to perform a bulk insert on MySQL. I'm using Hibernate 3.3 and MySQL 5.1 At a high level, this is what's happening: @Transactional public Set<Long> doUpdate(Project project, IRepository externalSource) { List<IEntity> entities = externalSource.loadEntites(); buildEntities(entities, project); persistEntities(project); } public void persistEntities(Project project) { projectDAO.update(project); } This results in n log entries (1 for every row) as follows: Hibernate: insert into ProjectEntity (name, parent_id, path, project_id, state, type) values (?, ?, ?, ?, ?, ?) I'd like to see this get batched, so the update is more performant. It's possible that this routine could result in tens-of-thousands of rows generated, and a db trip per row is a killer. Why isn't this getting batched? (It's my understanding that batch inserts are supposed to be default where appropriate by hibernate).

  • How to convert Beautiful Soup Unicode into a decimal value?

    - by MikeTheCoder
    I'm trying to Use python's Beautiful Soup Library to grab a bunch of divs from an html file, and from there get the string - which is a money value - that's inside the div. Then remove the dollar sign and convert it to a decimal so that I can use a greater than and less than conditional statement to compare values. I have googled the heck out of it and can't seem to come up with a way to convert this unicode string into a decimal value. I really could use some help here. How do I convert unicode into a decimal value? This was my last attempt: import unicodedata from bs4 import BeautifulSoup soup = BeautifulSoup(open("/Users/sm/Documents/python/htmldemo.html")) for tag in soup.findAll("div",attrs={"itemprop":"price"}) : val = tag.string new_val = val[8:] workable = int(new_val) if workable > 250: print(type(workable)) else: print(type(workable)) Edit: When I print the type of new_val I get : print(type(new_val))
