  • mySQL not saving data?

    - by tony noriega
    i have a PHP contact form that submits data, and an email...: <?php $dbh=mysql_connect ("localhost", "username", "password") or die ('I cannot connect to the database because: ' . mysql_error()); mysql_select_db ("guest"); if (isset($_POST['submit'])) { if (!$_POST['name'] | !$_POST['email']) { echo"<div class='error'>Error<br />Please provide your Name and Email Address so we may properly contact you.</div>"; } else { $age = $_POST['age']; $name = $_POST['name']; $gender = $_POST['gender']; $email = $_POST['email']; $phone = $_POST['phone']; $comments = $_POST['comments']; $query = "INSERT INTO contact_us (age,name,gender,email,phone,comments) VALUES ('$age','$name','$gender','$email','$phone','$comments')"; mysql_query($query); mysql_close(); $yoursite = "Mysite "; $youremail = $email; $subject = "Website Guest Contact Us Form"; $message = "$name would like you to contact them Contact PH: $phone Email: $email Age: $age Gender: $gender Comments: $comments"; $email2 = "[email protected]"; mail($email2, $subject, $message, "From: $email"); echo"<div class='thankyou'>Thank you for contacting us,<br /> we will respond as soon as we can.</div>"; } } ?> The email is coming through fine, but the data is not storing the dbase... am i missing something? Its the same script as i use on another contact us page, only difference is instead of parsing the data on teh same page, i now send this data to a "thankyou.php" page... i tried changing $_POST to $_GET but that killed the page... what am i doing wrong?

  • Foreign/accented characters in sql query

    - by FromCanada
    I'm using Java and Spring's JdbcTemplate class to build an SQL query in Java that queries a Postgres database. However, I'm having trouble executing queries that contain foreign/accented characters. For example the (trimmed) code: JdbcTemplate select = new JdbcTemplate( postgresDatabase ); String query = "SELECT id FROM province WHERE name = 'Ontario';"; Integer id = select.queryForObject( query, Integer.class ); will retrieve the province id, but if instead I did name = 'Québec' then the query fails to return any results (this value is in the database so the problem isn't that it's missing). I believe the source of the problem is that the database I am required to use has the default client encoding set to SQL_ASCII, which according to this prevents automatic character set conversions. (The Java environments encoding is set to 'UTF-8' while I'm told the database uses 'LATIN1' / 'ISO-8859-1') I was able to manually indicate the encoding when the resultSets contained values with foreign characters as a solution to a previous problem with a similar nature. Ex: String provinceName = new String ( resultSet.getBytes( "name" ), "ISO-8859-1" ); But now that the foreign characters are part of the query itself this approach hasn't been successful. (I suppose since the query has to be saved in a String before being executed anyway, breaking it down into bytes and then changing the encoding only muddles the characters further.) Is there a way around this without having to change the properties of the database or reconstruct it? PostScript: I found this function on StackOverflow when making up a title, it didn't seem to work (I might not have used it correctly, but even if it did work it doesn't seem like it could be the best solution.):

  • Adding a Taxonomy Filter to a Custom Post Type

    - by ken
    There is an amazing conversation from about two years ago on the Wordpress Answer site where a number of people came up with good solutions for adding a taxonomy filter to the admin screen for your custom post types (see URL for screen I'm referring to): http://[yoursite.com]/wp-admin/edit.php?s&post_status=all&post_type=[post-type] Anyway, I loved Michael's awesome contribution but in the end used Somatic's implementation with the hierarchy option from Manny. I wrapped it in a class - cuz that's how I like to do things -- and it ALMOST works. The dropdown appears but the values in the dropdown are all looking in the $_GET property for the taxonomies slug-name that you are filtering by. For some reason I don't get anything. I looked at the HTML of the dropdown and it appears ok to me. Here's a quick screen shot for some context: You can tell from this that my post-type is called "exercise" and that the Taxonomy I'm trying to use as a filter is "actions". Here then is the HTML surrounding the dropdown list: <select name="actions" id="actions" class="postform"> <option value="">Show all Actions</option> <option value="ate-dinner">Ate dinner(1)</option> <option value="went-running">Went running(1)</option> </select> I have also confirmed that all of the form elements are within the part of the DOM. And yet if I choose "Went running" and click on the filter button the URL query string comes back without ANY reference to what i've picked. More explicitly, the page first loads with the following URL: /wp-admin/edit.php?post_type=exercise and after pressing the filter button while having picked "Went Running" as an option from the actions filter: /wp-admin/edit.php?s&post_status=all&post_type=exercise&action=-1&m=0&actions&paged=1&mode=list&action2=-1 actually you can see a reference to an "actions" variable but it's set to nothing and as I now look in detail it appears that the moment I hit "filter" on the page it resets the filter dropdown to the default "Show All Actions". Can anyone help me with this?

  • Advanced tasks using Web.Config transformation

    - by dcadenas
    Does anyone know if there is a way to "transform" specific sections of values instead of replacing the whole value or an attribute? For example, I've got several appSettings entries that specify the Urls for different webservices. These entries are slightly different in the dev environment than the production environment. Some are less trivial than others <!-- DEV ENTRY --> <appSettings> <add key="serviceName1_WebsService_Url" value="http://wsServiceName1.dev.domain.com/v1.2.3.4/entryPoint.asmx" /> <add key="serviceName2_WebsService_Url" value="http://ma1-lab.lab1.domain.com/v1.2.3.4/entryPoint.asmx" /> </appSettings> <!-- PROD ENTRY --> <appSettings> <add key="serviceName1_WebsService_Url" value="http://wsServiceName1.prod.domain.com/v1.2.3.4/entryPoint.asmx" /> <add key="serviceName2_WebsService_Url" value="http://ws.ServiceName2.domain.com/v1.2.3.4/entryPoint.asmx" /> </appSettings> So far, I know I can do something like this in the Web.Release.Config: <add xdt:Locator="Match(key)" xdt:Transform="SetAttributes(value)" key="serviceName1_WebsService_Url" value="http://wsServiceName1.prod.domain.com/v1.2.3.4/entryPoint.asmx" /> <add xdt:Locator="Match(key)" xdt:Transform="SetAttributes(value)" key="serviceName2_WebsService_Url" value="http://ws.ServiceName2.domain.com/v1.2.3.4/entryPoint.asmx" /> However, everytime the Version for that webservice is updated, I would have to update the Web.Release.Config as well, which defeats the purpose of simplfying my web.config updates. I know I could also split that URL into different sections and update them independently, but I rather have it all in one key. I've looked through the available web.config Transforms but nothings seems to be geared towars what I am trying to accomplish. These are the websites I am using as a reference: Vishal Joshi's blog, MSDN Help, and Channel9 video Any help would be much appreciated! -D

  • Setting an Excel Range with an Array using Python and comtypes?

    - by technomalogical
    Using comtypes to drive Python, it seems some magic is happening behind the scenes that is not converting tuples and lists to VARIANT types: # RANGE(“C14:D21”) has values # Setting the Value on the Range with a Variant should work, but # list or tuple is not getting converted properly it seems >>>from comtypes.client import CreateObject >>>xl = CreateObject("Excel.application") >>>xl.Workbooks.Open(r'C:\temp\my_file.xlsx') >>>xl.Visible = True >>>vals=tuple([(x,y) for x,y in zip('abcdefgh',xrange(8))]) # creates: #(('a', 0), ('b', 1), ('c', 2), ('d', 3), ('e', 4), ('f', 5), ('g', 6), ('h', 7)) >>>sheet = xl.Workbooks[1].Sheets["Sheet1"] >>>sheet.Range["C14","D21"].Value() (('foo',1),('foo',2),('foo',3),('foo',4),('foo',6),('foo',6),('foo',7),('foo',8)) >>>sheet.Range["C14","D21"].Value[()] = vals # no error, this blanks out the cells in the Range According to the comtypes docs: When you pass simple sequences (lists or tuples) as VARIANT parameters, the COM server will receive a VARIANT containing a SAFEARRAY of VARIANTs with the typecode VT_ARRAY | VT_VARIANT. This seems to be inline with what MSDN says about passing an array to a Range's Value. I also found this page showing something similar in C#. Can anybody tell me what I'm doing wrong? EDIT I've come up with a simpler example that performs the same way (in that, it does not work): >>>from comtypes.client import CreateObject >>>xl = CreateObject("Excel.application") >>>xl.Workbooks.Add() >>>sheet = xl.Workbooks[1].Sheets["Sheet1"] # at this point, I manually typed into the range A1:B3 >>> sheet.Range("A1","B3").Value() ((u'AAA', 1.0), (u'BBB', 2.0), (u'CCC', 3.0)) >>>sheet.Range("A1","B3").Value[()] = [(x,y) for x,y in zip('xyz',xrange(3))] # Using a generator expression, per @Mike's comment # However, this still blanks out my range :(

  • MySQL FULLTEXT not working

    - by Ross
    I'm attempting to add searching support for my PHP web app using MySQL's FULLTEXT indexes. I created a test table (using the MyISAM type, with a single text field a) and entered some sample data. Now if I'm right the following query should return both those rows: SELECT * FROM test WHERE MATCH(a) AGAINST('databases') However it returns none. I've done a bit of research and I'm doing everything right as far as I can tell - the table is a MyISAM table, the FULLTEXT indexes are set. I've tried running the query from the prompt and from phpMyAdmin, with no luck. Am I missing something crucial? UPDATE: Ok, while Cody's solution worked in my test case it doesn't seem to work on my actual table: CREATE TABLE IF NOT EXISTS `uploads` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` text NOT NULL, `size` int(11) NOT NULL, `type` text NOT NULL, `alias` text NOT NULL, `md5sum` text NOT NULL, `uploaded` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=6 ; And the data I'm using: INSERT INTO `uploads` (`id`, `name`, `size`, `type`, `alias`, `md5sum`, `uploaded`) VALUES (1, '04 Sickman.mp3', 5261182, 'audio/mp3', '1', 'df2eb6a360fbfa8e0c9893aadc2289de', '2009-07-14 16:08:02'), (2, '07 Dirt.mp3', 5056435, 'audio/mp3', '2', 'edcb873a75c94b5d0368681e4bd9ca41', '2009-07-14 16:08:08'), (3, 'header_bg2.png', 16765, 'image/png', '3', '5bc5cb5c45c7fa329dc881a8476a2af6', '2009-07-14 16:08:30'), (4, 'page_top_right2.png', 5299, 'image/png', '4', '53ea39f826b7c7aeba11060c0d8f4e81', '2009-07-14 16:08:37'), (5, 'todo.txt', 392, 'text/plain', '5', '7ee46db77d1b98b145c9a95444d8dc67', '2009-07-14 16:08:46'); The query I'm now running is: SELECT * FROM `uploads` WHERE MATCH(name) AGAINST ('header' IN BOOLEAN MODE) Which should return row 3, header_bg2.png. Instead I get another empty result set. My options for boolean searching are below: mysql> show variables like 'ft_%'; +--------------------------+----------------+ | Variable_name | Value | +--------------------------+----------------+ | ft_boolean_syntax | + -><()~*:""&| | | ft_max_word_len | 84 | | ft_min_word_len | 4 | | ft_query_expansion_limit | 20 | | ft_stopword_file | (built-in) | +--------------------------+----------------+ 5 rows in set (0.02 sec) "header" is within the word length restrictions and I doubt it's a stop word (I'm not sure how to get the list). Any ideas?

  • Wireshark Dissector: How to Identify Missing UDP Frames?

    - by John Dibling
    How do you identify missing UDP frames in a custom Wireshark dissector? I have written a custom dissector for the CQS feed (reference page). One of our servers gaps when receiving this feed. According to Wireshark, some UDP frames are never received. I know that the frames were sent because all of our other servers are gap-free. A CQS frame consists of multiple messages, each having its own sequence number. My custom dissector provides the following data to Wireshark: cqs.frame_gaps - the number of gaps within a UDP frame (always zero) cqs.frame_first_seq - the first sequence number in a UDP frame cqs.frame_expected_seq - the first sequence number expected in the next UDP frame cqs.frame_msg_count - the number of messages in this UDP frame And I am displaying each of these values in custom columns, as shown in this screenshot: I tried adding code to my dissector that simply saves the last-processed sequence number (as a local static), and flags gaps when the dissector processes a frame where current_sequence != (previous_sequence + 1). This did not work because the dissector can be called in random-access order, depending on where you click in the GUI. So you could process frame 10, then frame 15, then frame 11, etc. Is there any way for my dissector to know if the frame that came before it (or the frame that follows) is missing? The dissector is written in C. (See also a companion post on serverfault.com)

  • Is a GWT app running on Google App Engine protected from CSRF

    - by gerdemb
    I'm developing a GWT app running on the Google App Engine and wondering if I need to worry about Cross-site request forgery or is that automatically taken care of for me? For every RPC request that requires authentication, I have the following code: public class BookServiceImpl extends RemoteServiceServlet implements BookService { public void deleteInventory(Key<Inventory> inventoryKey) throws NotLoggedInException, InvalidStateException, NotFoundException { DAO dao = new DAO(); // This will throw NotLoggedInException if user is not logged in User user = dao.getCurrentUser(); // Do deletion here } } public final class DAO extends DAOBase { public User getCurrentUser() throws NotLoggedInException { currentUser = UserServiceFactory.getUserService().getCurrentUser(); if(currentUser == null) { throw new NotLoggedInException(); } return currentUser; } I couldn't find any documentation on how the UserService checks authentication. Is it enough to rely on the code above or do I need to to more? I'm a beginner at this, but from what I understand to avoid CSRF attacks some of the strategies are: adding an authentication token in the request payload instead of just checking a cookie checking the HTTP Referer header I can see that I have cookies set from Google with what look like SID values, but I can't tell from the serialized Java objects in the payloads if tokens are being passed or not. I also don't know if the Referer header is being used or not. So, am I worrying about a non-issue? If not, what is the best strategy here? This is a common enough problem, that there must be standard solutions out there...

  • NULL-keys for key/value table

    - by user72185
    (Using Oracle) I have a table with key/value pairs like this: create table MESSAGE_INDEX ( KEY VARCHAR2(256) not null, VALUE VARCHAR2(4000) not null, MESSAGE_ID NUMBER not null ) I now want to find all the messages where key = 'someKey' and value is 'val1', 'val2' or 'val3' - OR value is null in which case there will be no entry in the table at all. This is to save space; there would be a large number of keys with null values if I stored them all. I think this works: SELECT message_id FROM message_index idx WHERE ((key = 'someKey' AND value IN ('val1', 'val2', 'val3')) OR NOT EXISTS (SELECT 1 FROM message_index WHERE key = 'someKey' AND idx.message_id = message_id)) But is is extremely slow. Takes 8 seconds with 700K records in message_index and there will be many more records and more search criteria when moving outside of my test environment. Primary key is key, value, message_id: add constraint PK_KEY_VALUE primary key (KEY, VALUE, MESSAGE_ID) And I added another index for message_id, to speed up searching for missing keys: create index IDX_MESSAGE_ID on MESSAGE_INDEX (MESSAGE_ID) I will be doing several of these key/value lookups in every search, not just one as shown above. So far I am doing them nested, where output id's of one level is the input to the next. E.g.: SELECT message_id from message_index WHERE (key/value compare) AND message_id IN ( SELECT ... and so on ) What can I do to speed this up?

  • Geolocation and jQuery - Can't post results using ajax

    - by etombaugh
    I'm currently working on a project to make a location-aware site. In essence, the user comes to the page, and their location is found using the HTML5 method and then using jQuery, the location is posted to a page which saves the location/address to a codeigniter session, but if they want to update their location, or change to a different location(IE they want to use their work address as the location instead of their present address), theres a jQuery colorbox that displays and lets them type in a custom address. Everything works flawlessly to get the initial location, but when I try and get the updated location saved, I receive the error "Uncaught TypeError: Object [object DOMWindow] has no method 'lat'" which then Google Chrome references as being an error not in jQuery, but in the file for Google Maps API. Any suggestions? jQuery('.inputsubmit').click(function() { //Takes values from user submitted fields and parses them into an address string var street = jQuery('.inputaddress').val(); var city = jQuery('.inputcity').val(); var state = jQuery('.inputstate').val(); var address = street +" "+ city +", " +state; geocoder = new google.maps.Geocoder(); var geocoderresult= geocoder.geocode({'address': address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { var newlocation = results[0].geometry.location; //Posts coordinates and address string to a CodeIgniter function to update users session information jQuery.post("somepage", {location: newlocation, address: address},function(data) { alert("Data Loaded: " + data); }); } else { alert("Geocoder failed due to: " + status); } }); }); I've tried everything I can think of to get the post to work. All of the code works up till the point, and I've commented out the post line and everything works correctly. This is one of our main website's features, to provide instant and quick results based off of location. Thanks!

  • Color picker does not give gradient appearance

    i added below codes. But it generates to me 16 color. but i need 16 color between "red" and "khaki". i don't need gradient flow. My colors look like gradient flow.

  • Lazy Sequences that "Look Ahead" for Project Euler Problem 14

    - by ivar
    I'm trying to solve Project Euler Problem 14 in a lazy way. Unfortunately, I may be trying to do the impossible: create a lazy sequence that is both lazy, yet also somehow 'looks ahead' for values it hasn't computed yet. The non-lazy version I wrote to test correctness was: (defn chain-length [num] (loop [len 1 n num] (cond (= n 1) len (odd? n) (recur (inc len) (+ 1 (* 3 n))) true (recur (inc len) (/ n 2))))) Which works, but is really slow. Of course I could memoize that: (def memoized-chain (memoize (fn [n] (cond (= n 1) 1 (odd? n) (+ 1 (memoized-chain (+ 1 (* 3 n)))) true (+ 1 (memoized-chain (/ n 2))))))) However, what I really wanted to do was scratch my itch for understanding the limits of lazy sequences, and write a function like this: (def lazy-chain (letfn [(chain [n] (lazy-seq (cons (if (odd? n) (+ 1 (nth lazy-chain (dec (+ 1 (* 3 n))))) (+ 1 (nth lazy-chain (dec (/ n 2))))) (chain (+ n 1)))))] (chain 1))) Pulling elements from this will cause a stack overflow for n2, which is understandable if you think about why it needs to look 'into the future' at n=3 to know the value of the tenth element in the lazy list because (+ 1 (* 3 n)) = 10. Since lazy lists have much less overhead than memoization, I would like to know if this kind of thing is possible somehow via even more delayed evaluation or queuing?

  • is it possible to write a method which creates a method?

    - by Alan Bennett
    hey guys, this might seem like a no brainer but hopefully after i explain my problem you might understand why i am asking this. is it possible to have a method which creates a method and its arguements? the problem: in my current project i have to many times call different sql statements which arent all that different. for example i have one where i inserts some new rows but only has 2 columns and another which also inserts new rows but has 12 columns. i have created a class called utils.cs and in there i have sorted many "handy" methods, such as validation methods which check for numeric input to text boxes etc. so i thought well instead of having sql writing methods everywhere ill make one in there and call it when i need to so i have but it currently looks like this: public static string getInsertSQL(string tablename, string colOne, string colTwo, string colThree, string colFour, string colFive, string colSix, string colSeven, string colEight, string colNine, string colTen, string colEleven, string colTwelve,bool active, string valueOne, string valueTwo, string valueThree, string valueFour, string valueFive, string valueSix, string valueSeven, string valueEight, string valueNine, string valueTen, string valueEleven) { string strSQL = ""; strSQL += "INSERT INTO " + tablename; strSQL += "(" + colOne + " " + colTwo + " " + colThree + " " + colFour + " " + colFive + " " + colSix + " " + colSeven + " " + colEight + " " + colNine + " " + colTen + " " + colEleven + " " + colTwelve + " )"; strSQL += " values ("+active+", " + valueOne + " " + valueTwo + " " + valueThree + " " + valueFour + " " + valueFive + " " + valueSix + " " + valueSeven + " " + valueEight + " " + valueNine + " " + valueTen + " " + valueEleven + " )"; return strSQL; } as you can see thats quite a mess so i wondered if it was at all possible to write a method which would take an arguement of how many colums needed to be inserted and then could create a method with that many arguements. i hope you can see what i am getting at and dont just sound like a plep! thanks in advance

  • MySQL FULLTEXT aggravation

    - by southof40
    Hi - I'm having problems with case-sensitivity in MySQL FULLTEXT searches. I've just followed the FULLTEXT example in the MySQL doco at http://dev.mysql.com/doc/refman/5.1/en/fulltext-boolean.html . I'll post it here for ease of reference ... CREATE TABLE articles ( id INT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY, title VARCHAR(200), body TEXT, FULLTEXT (title,body) ); INSERT INTO articles (title,body) VALUES ('MySQL Tutorial','DBMS stands for DataBase ...'), ('How To Use MySQL Well','After you went through a ...'), ('Optimizing MySQL','In this tutorial we will show ...'), ('1001 MySQL Tricks','1. Never run mysqld as root. 2. ...'), ('MySQL vs. YourSQL','In the following database comparison ...'), ('MySQL Security','When configured properly, MySQL ...'); SELECT * FROM articles WHERE MATCH (title,body) AGAINST ('database' IN NATURAL LANGUAGE MODE); ... my problem is that the example shows that SELECT returning the first and fifth rows ('..DataBase..' and '..database..') but I only get one row ('database') ! The example doesn't demonstrate what collation the table in the example had but I have ended up with latin1_general_cs on the title and body columns of my example table. My version of MySQL is 5.1.39-log and the connection collation is utf8_unicode_ci . I'd be really grateful is someone could suggest why my experience differs from the example in the manual ! Be grateful for any advice.

  • How to prevent external translation of a movieclip object on stage in AS3?

    - by Aaron H.
    I have a MovieClip object, which is exported for actionscript (AS3) in an .swc file. When I place an instance of the clip on the stage without any modifications, it appears in the upper left corner, about half off stage (i.e. only the lower right quadrant of the object is visible). I understand that this is because the clip has a registration point which is not the upper left corner. If you call getBounds() on the movieclip you can get the bounds of the clip (presumably from the "point" that it's aligned on) which looks something like (left: -303, top: -100, right: 303, bottom: 100), you can subtract the left and top values from the clip x and y: clip.x -= bounds.left; clip.y -= bounds.top; This seems to properly align the clip fully on stage with the top left of the clip squarely in the corner of the stage. But! Following that logic doesn't seem to work when aligning it on the center of the stage! clip.x = (stage.stageWidth / 2); etc... This creates the crazy parallel universe where the clip is now down in the lower right corner of the stage. The only clue I have is that looking at: clip.transform.matrix and clip.transform.concatenatedMatrix matrix has a tx value of 748 (half of stage height) ty value of 426 (Half of stage height) concatenatedMatrix has a tx value of 1699.5 and ty value of 967.75 That's also obviously where the movieclip is getting positioned, but why? Where is this additional translation coming from?

  • Using Partitions for a large MySQL table

    - by user293594
    An update on my attempts to implement a 505,000,000-row table on MySQL on my MacBook Pro: Following the advice given, I have partitioned my table, tr: i UNSIGNED INT NOT NULL, j UNSIGNED INT NOT NULL, A FLOAT(12,8) NOT NULL, nu BIGINT NOT NULL, KEY (nu), key (A) with a range on nu. nu ought to be a real number, but because I only have 6-d.p. accuracy and the maximum value of nu is 30000. I multiplied it by 10^8 made it a BIGINT - I gather one can't use FLOAT or DOUBLE values to PARTITION a MySQL table. Anyway, I have 15 partitions (p0: nu<25,000,000,000, p1: nu<50,000,000,000, etc.). I was thinking that this should speed up a typical to SELECT: SELECT * FROM tr WHERE nu>95000000000 AND nu<100000000000 AND A.>1. to something of the order of the same query on a table consisting of only the data in the relevant partition (<30 secs). But it's taking 30mins+ to return rows for queries within a partition and double that if the query is for rows spanning two (contiguous) partitions. I realise I could just have 15 different tables, and query them separately, but is there a way to do this 'automatically' with partitions? Has anyone got any suggestions?

  • Using data binding on value which is a FrameworkElement

    One of my data sources produces a collection of values which are typed to the following interface public interface IData { string Name { get; } FrameworkElement VisualElement { get; } } I'd like to use data binding in WPF to display a collection of IData instances in a TabControl where the Name value becomes the header of the tab and the VisualElement value is displayed as the content of the corresponding tab. Binding the header is straight forward. I'm stuck though on how to define a template which allows me to display the VisualElement value. I've tried a number of solutions with little success. My best attempt is as follows. <TabControl ItemsSource="{Binding}"> <TabControl.ItemTemplate> <DataTemplate> <Label Content="{Binding Name}"/> </DataTemplate> </TabControl.ItemTemplate> <TabControl.ContentTemplate> <DataTemplate> How do I display VisualElement here? </DataTemplate> </TabControl.ContentTemplate> </TabControl> I'm still very new to WPF so I could be missing the obvious here.

  • How to check if JavaScript object is JSON

    - by Wei Hao
    I have a nested JSON object that I need to loop through, and the value of each key could be a String, JSON array or another JSON object. Depending on the type of object, I need to carry out different operations. Is there any way I can check the type of the object to see if it is a String, JSON object or JSON array? I tried using typeof and instanceof but both didn't seem to work, as typeof will return an object for both JSON object and array, and instanceof gives an error when I do obj instanceof JSON. To be more specific, after parsing the JSON into a JS object, is there any way I can check if it is a normal string, or an object with keys and values (from a JSON object), or an array (from a JSON array)? For example: JSON var data = {"hi": {"hello": ["hi1","hi2"] }, "hey":"words" } JavaScript var jsonObj = JSON.parse(data); var level1 = jsonObj.hi; var text = jsonObj.hey; var arr = level1.hello; //how to check if level1 was formerly a JSON object? //how to check if arr was formerly a JSON array? //how to check if text is a string?

  • Pass a range into a custom function from within a cell

    - by Luis
    Hi I'm using VBA in Excel and need to pass in the values from two ranges into a custom function from within a cell's formula. The function looks like this: Public Function multByElement(range1 As String, range2 As String) As Variant Dim arr1() As Variant, arr2() As Variant arr1 = Range(range1).value arr2 = Range(range2).value If UBound(arr1) = UBound(arr2) Then Dim arrayA() As Variant ReDim arrayA(LBound(arr1) To UBound(arr1)) For i = LBound(arr1) To UBound(arr1) arrayA(i) = arr1(i) * arr2(i) Next i multByElement = arrayA End If End Function As you can see, I'm trying to pass the string representation of the ranges. In the debugger I can see that they are properly passed in and the first visible problem occurs when it tries to read arr1(i) and shows as "subscript out of range". I have also tried passing in the range itself (ie range1 as Range...) but with no success. My best suspicion was that it has to do with the Active Sheet since it was called from a different sheet from the one with the formula (the sheet name is part of the string) but that was dispelled since I tried it both from within the same sheet and by specifying the sheet in the code. BTW, the formula in the cell looks like this: =AVERAGE(multByElement("A1:A3","B1:B3")) or =AVERAGE(multByElement("My Sheet1!A1:A3","My Sheet1!B1:B3")) for when I call it from a different sheet.

  • Android WebView viewport

    - by alex2k8
    With html below I expected that the green rectangle would occupy only half of the screen, but on practice it occupies the whole screen width. I tried other values for viewport width, no luck. Any ideas why it does not work? Html <html> <head> <meta name="viewport" content="width=640" /> </head> <body> <div style="width: 300px; height: 50px; background: green;">300px</div> <div style="width: 600px; height: 50px; background: yellow;">600px</div> </body> </html> Xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <WebView android:id="@+id/web_view" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>

  • NSDictionary, NSArray, NSSet and efficiency

    - by ryyst
    Hi, I've got a text file, with about 200,000 lines. Each line represents an object with multiple properties. I only search through one of the properties (the unique ID) of the objects. If the unique ID I'm looking for is the same as the current object's unique ID, I'm gonna read the rest of the object's values. Right now, each time I search for an object, I just read the whole text file line by line, create an object for each line and see if it's the object I'm looking for - which is basically the most inefficient way to do the search. I would like to read all those objects into memory, so I can later search through them more efficiently. The question is, what's the most efficient way to perform such a search? Is a 200,000-entries NSArray a good way to do this (I doubt it)? How about an NSSet? With an NSSet, is it possible to only search for one property of the objects? Thanks for any help! -- Ry

  • Dimension Mismatch MatLab; cant figure out why it is mismatching

    - by Abid
    I think it may be a syntax issue, here is the code. load ([ 'C:\Users\Abid\Desktop\Inquiry Runs\dtS' ]) dtS((dtS==0))=nan; for j=2:9; maxS=max(dtS(j,:)); minS=min(dtS(j,:)); maxval(j,:)=dtS((dtS>(maxS-.1*maxS))); minval(j,:)=dtS((dtS<(minS+.1*minS))); avmax(j)=mean(maxval(j,:)); avmin(j)=mean(minval(j,:)); avs(j,:)=[avmax(j) avmin(j)] end So I know the the row matrices are different sizes every loop. For example maxval(j,:) will change depending one row it is looking through for certain values. I did this manually and I see that on the first loop the matrices are size (1,1), however, if I set the loop to run for only j=2, the row length is 13. Usually if a matrix is changing size on the loop, I only get a warning, but this time I think it is due to a reason I don't understand.

  • array or list into Oracle using cfprocparam

    - by Travis
    I have a list of values I want to insert into a table via a stored procedure. I figured I would pass an array to oracle and loop through the array but I don't see how to pass an array into Oracle. I'd pass a list but I don't see how to work with the list to turn it into an array using PL/SQL (I'm fairly new to PL/SQL). Am I approaching this the wrong way? Using Oracle 9i and CF8. TIA! EDIT Perhaps I'm thinking about this the wrong way? I'm sure I'm not doing anything new here... I figured I'd convert the list to an associative array then loop the array because Oracle doesn't seem to work well with lists (in my limited observation). I'm trying to add a product, then add records for the management team. -- product table productName = 'foo' productDescription = 'bar' ... ... etc -- The managementteam table just has the id of the product and id of the users selected from a drop down. The user IDs are passed in via a list like "1,3,6,20" How should I go about adding the records to the management team table?

  • Android ExpandableListView From Database

    - by SterAllures
    I want to create a two level ExpandableListView from a local database. The group level I want to get the names from the database Category table category_id | name ------------------- 1 | NameOfCategory the children level I want to get the names from the List table list_id | name | foreign_category_id -------------------------------- 1 | Listname | 1 I've got a method in DatabaseDAO to get all the values from the table public List<Category> getAllCategories() { database = dbHelper.getReadableDatabase(); List<Category> categories = new ArrayList<Category>(); Cursor cursor = database.query(SQLiteHelper.TABLE_CATEGORY, null, null, null, null, null, null); cursor.moveToFirst(); while(!cursor.isAfterLast()) { Category category = cursorToCategory(cursor); categories.add(category); cursor.moveToNext(); } cursor.close(); return categories; } Now adding the names to the group level is easy I do it the following way: ArrayList<String> groups; for(Category c : databaseDao.getAllCategories()) { groups.add(c.getName()); } Now I want to add the children to the ExpandableListView in the following array ArrayList<ArrayList<ArrayList<String>>> children;. How do I get the children under the correct group name? I think it has to do somenthing with groups.indexOf() but in the list table I only have a foreign category_id and not the actual name.
