  • <button type="submit"> compatibility?

    - by Mark
    I'd like to have a submit button that submits a different value than is displayed on the button. With <input type="submit"> you can't seem to do this. With <button type="submit"> however, these can be two different values. The question is, will it work in all browsers? Trying this test code here: <form method="get" action=""> <input type="text" name="txt"/> <button type="submit" name="btn" value="val">text</button> </form> In FF 3.6 it updates my address bar with both values appropriately (and responds to me pressing enter in the text box). In IE 8, it also accepts pressing enter, displays the text value in the address bar, but it show the button's value as a GET param at all... does that mean it's not submitting it?

  • C/C++ enums: Detect when multiple items map to same value

    - by Dan
    Is there a compile-time way to detect / prevent duplicate values within a C/C++ enumeration? The catch is that there are multiple items which are initialized to explicit values. Background: I've inherited some C code such as the following: #define BASE1_VAL (5) #define BASE2_VAL (7) typedef enum { MsgFoo1A = BASE1_VAL, // 5 MsgFoo1B, // 6 MsgFoo1C, // 7 MsgFoo1D, // 8 MsgFoo1E, // 9 MsgFoo2A = BASE2_VAL, // Uh oh! 7 again... MsgFoo2B // Uh oh! 8 again... } FOO; The problem is that as the code grows & as developers add more messages to the MsgFoo1x group, eventually it overruns BASE2_VAL. This code will eventually be migrated to C++, so if there is a C++-only solution (template magic?), that's OK -- but a solution that works with C and C++ is better.

  • sql - duplicates

    - by Sebastjan
    Hey guys I'm putting data from website (json) to sql base. In db i have these rows. ID | PostId | Name | Message Id is auto-increment primary key. PostId also has a unique values. Name and Message are nothing special. When I run my script / click on the button in form / ... , the program saves all the values into database (lets say there are 25). Next time I'm going to press the button there will be added 25 more records (all duplicates), and so on... Is there a way that the program can check through 'PostIds' if the value already exists before adding it to the db? Thanks

  • movedown method not saving new position - cakephp tree

    - by Ryan
    Hi everyone, I am experiencing a problem that has popped up recently and is causing quite a bit of trouble for our system. The app we have relies on using the movedown method to organize content, but as of late it has stopped working and began to generate the following warning: Warning (2): array_values() [<a href='function.array-values'>function.array-values</a>]: The argument should be an array in [/usr/local/home/cake/cake_0_2_9/cake/libs/model/behaviors/tree.php, line 459] The line being referenced: list($node) = array_values($Model->find('first', array( 'conditions' => array($scope, $Model->escapeField() => $id), 'fields' => array($Model->primaryKey, $left, $right, $parent), 'recursive' => $recursive ))); The line calling the method: $this->movedown($id,abs((int)$position)); I have exhausted every idea I could come up with. Has anyone else crossed this issue before? Any help, or pointing in a direction would be much appreciated!

  • Insert into select and update in single query

    - by Ossi
    I have 4 tables: tempTBL, linksTBL and categoryTBL, extra on my tempTBL I have: ID, name, url, cat, isinserted columns on my linksTBL I have: ID, name, alias columns on my categoryTBL I have: cl_id, link_id,cat_id on my extraTBL I have: id, link_id, value How do I do a single query to select from tempTBL all items where isinsrted = 0 then insert them to linksTBL and for each record inserted, pickup ID (which is primary) and then insert that ID to categoryTBL with cat_id = 88. after that insert extraTBL ID for link_id and url for value. I know this is so confusing, put I'll post this anyhow... This is what I have so far: INSERT IGNORE INTO linksTBL (link_id,link_name,alias) VALUES(NULL,'tex2','hello'); # generate ID by inserting NULL INSERT INTO categoryTBL (link_id,cat_id) VALUES(LAST_INSERT_ID(),'88'); # use ID in second table I would like to add here somewhere that it only selects items where isinserted = 0 and iserts those records, and onse inserted, will change isinserted to 1, so when next time it runs, it will not add them again.

  • Clear the form once form submitted

    - by zurna
    Once the form submitted, response from another page is printed to #GameStorySys. But values entered to the form still stays there. Is it possible for the form values to disappear (but the form should still stay) once the form submitted? $("[name='GameStoryForm']").click(function() { $.ajax({ type: "POST", data: $("#GameStoryForm").serialize(), url: "content/commentary/index.cs.asp?Process=EditLiveCommentaryStory&CommentaryID=<%=Request.QueryString("CommentaryID")%>", success: function(output) { $('#GameStorySys').html(output); }, error: function(output) { $('#GameStorySys').html(output); } }); });

  • Implementing a Risk-style board

    - by pouzzler
    I have two images of the same dimensions. One is represents the game board in a user-appealing way, the other represents it in a computer-friendly way where each game area is painted in a unique, uniform color. When the user clicks the board, we get the click coordinates, find the color of the pixel at the same coordinates in our second image, and that color is directly translatable to a game area, since each area is painted in its own color. Is that a good implementation? Can you suggest better, if it isn't? Best regards.

  • Trying to zoom in on an arbitrary rect within a screen-aligned quad.

    - by mos
    I've got a screen-aligned quad, and I'd like to zoom into an arbitrary rectangle within that quad, but I'm not getting my math right. I think I've got the translate worked out, just not the scaling. Basically, my code is the following: // // render once zoomed in glPushMatrix(); glTranslatef(offX, offY, 0); glScalef(?wtf?, ?wtf?, 1.0f); RenderQuad(); glPopMatrix(); // // render PIP display glPushMatrix(); glTranslatef(0.7f, 0.7f, 0); glScalef(0.175f, 0.175f, 1.0f); RenderQuad(); glPopMatrix(); Anyone have any tips? The user selects a rect area, and then those values are passed to my rendering object as [x, y, w, h], where those values are percentages of the viewport's width and height.

  • Why is there garbage in my TCHAR, even after ZeroMemory()?

    - by samoz
    I have inherited the following line of code: TCHAR temp[300]; GetModuleFileName(NULL, temp, 300); However, this fails as the first 3 bytes are filled with garbage values (always the same ones though, -128, -13, 23, in that order). I said, well fine and changed it to: TCHAR temp[300]; ZeroMemory(temp, 300); GetModuleFileName(NULL, temp, 300); but the garbage values persisted! Can someone explain what is going on and how to fix it?

  • Python: What's a correct and good way to implement __hash__()?

    - by random-name
    What's a correct and good way to implement hash()? I am talking about the function that returns a hashcode that is then used to insert objects into hashtables aka dictionaries. As hash() returns an integer and is used for "binning" objects into hashtables I assume that the values of the returned integer should be uniformly distributed for common data (to minimize collisions). What's a good practice to get such values? Are collisions a problem? In my case I have a small class which acts as a container class holding some ints, some floats and a string.

  • Combining IN and NOT IN in SQL as single result

    - by UltraVi01
    I apologize for the vague title. I am attempting to write a query that returns an alias column with matching values (resulting from an IN) as well as an alias column with values that do not match (using NOT IN). I want the result set to have: userId | matches | nonmatches. I currently have the following query which returns the matches as expected. I am having trouble getting the nonmatches in the result set -- that is, from a NOT IN statement SET @userId = 9; SELECT ug.user_id, COUNT(DISTINCT goal_id) as matches FROM user_goal ug WHERE ug.user_id!=@userId AND goal_id IN (SELECT iug.goal_id FROM user_goal iug WHERE user_id=@userId) GROUP BY user_id ORDER BY matches DESC LIMIT 4 So, the NOT IN would look something like this: goal_id NOT IN(SELECT uggg.goal_id FROM user_goal uggg WHERE user_id=@userId) AS nonmatches I am just not sure how to incorporate the NOT IN statement in my query so I get all the results

  • Make a simulation using python

    - by user3727759
    I am new to programming and using python. What I am trying to do is create a simulation of a thermostat system by using python. Is there a way to create a program that I can input data, for example temperature and humidity values and then have python constantly plotting the data as I enter the values. This is to simulate a device gathering data and sending it to this program and having it being plotted. I have found ways to plot data by using matplotlib but I have not been able to find a way that I can input the data and have the plot upgrade constantly. Thanks any advise is appreciated.

  • Number 0 is not saving to database as a prefix in SQL Server of CHAR data type column

    - by gmhk
    I am trying to insert an value as '019393' into a table with a CHAR(10) column. It is inserting only '19393' into the database I am implementing this feature in a stored procedure, doing some manipulation like incrementing that number by 15 and saving it back with '0' as the prefix I am using SQL Server database Note: I tried CASTING that value as VARCHAR before saving to the database, but even that did not get the solution Code SELECT @fromBSB = fromBSB, @toBSB = toBSB, @type = Type FROM [dbo].[tbl_REF_SpecialBSBRanges] WHERE CAST(@inputFromBSB AS INT) BETWEEN fromBSB AND toBSB SET @RETURNVALUE = @fromBSB IF(@fromBSB = @inputFromBSB) BEGIN PRINT 'Starting Number is Equal'; DELETE FROM tbl_REF_SpecialBSBRanges WHERE Type = @type AND fromBSB = @fromBSB AND toBSB = @toBSB INSERT INTO [tbl_REF_SpecialBSBRanges] ([Type], [fromBSB], [toBSB]) VALUES(@type, CAST('0' + @fromBSB + 1 AS CHAR), @toBSB) INSERT INTO [tbl_REF_SpecialBSBRanges] ([Type], [fromBSB], [toBSB]) VALUES(@inputBSBName, @inputFromBSB, @inputToBSB) END

  • numberOfSectionsInTable isn't called when [arr count] is returned

    - by user315471
    When I try returning the count of my newsItems array it breaks my application. I used NSLog to find out what the value of the newsItems count was when I returned 1. Here is from NSLog 2010-04-13 07:48:40.656 RSS Feed[453:207] Values of num items 31 2010-04-13 07:48:40.656 RSS Feed[453:207] Number of items 31 Does anyone know why returning [newsItems count] would cause my application to break? - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { NSLog(@"Values of num items %d",[newsItems count]); NSInteger *length = (NSInteger *)[newsItems count]; NSLog(@"Number of items %d",length); return 1; //return [newsItems count]; //This keeps breaking it for some reason }

  • Using jquery, what is the simplest function to post some json data and process a returned json respo

    - by Chris Boesch
    When users click on an element in my webpage, I would like to call a javascript function that reads the values of a few text boxes on the page, wraps their contents as json where the keys are the ids for the text boxes and the values are the contents of each text box, and then posts the resulting json to a url. I would then like the same function to expect back a json response and call another javascript function with the returned json data. Question: What is the best way to write the javascript function to create a json structure from html elements, post the json with jquery, and call another javascript function with the resulting json response from the server?

  • Can't figure out what's wrong with my php/sql statement

    - by Olegious
    So this is probably a dumb beginner question, but I've been looking at it and can't figure it out. A bit of background: just practicing making a web app, a form on page 1 takes in some values from the user, posts them to the next page which contains the code to connect to the DB and populate the relevant tables. I establish the DB connection successfully, here's the code that contains the query: $conn->query("SET NAMES 'utf9'"); $query_str = "INSERT INTO 'qa'.'users' ('id', 'user_name','password' ,'email' ,'dob' ,'sx') VALUES (NULL, $username, $password, $email, $dob, $sx);"; $result = @$conn->query($query_str); Here's the error that is returned:Insert query failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''qa'.'users' ('id', 'user_name' ,'password' ,'email' ,'dob' ,'s' at line 1 Thanks in advance!

  • Outer select column value in joined subquery?

    - by Michael DePetrillo
    Is it possible to use a column value from an outer select within a joined subquery? SELECT table1.id, table2.cnt FROM table1 LEFT JOIN (SELECT COUNT(*) as `cnt` FROM table2 where table2.lt > table1.lt and table2.rt < table1.rt) as table2 ON 1; This results in "Unknown column 'table1.lt' in 'where clause'". Here is the db dump. CREATE TABLE IF NOT EXISTS `table1` ( `id` int(1) NOT NULL, `lt` int(1) NOT NULL, `rt` int(4) NOT NULL) ENGINE=MyISAM DEFAULT CHARSET=latin1; CREATE TABLE IF NOT EXISTS `table2` ( `id` int(1) NOT NULL, `lt` int(1) NOT NULL, `rt` int(4) NOT NULL) ENGINE=MyISAM DEFAULT CHARSET=latin1; INSERT INTO `table1` (`id`, `lt`, `rt`) VALUES (1, 1, 4); INSERT INTO `table2` (`id`, `lt`, `rt`) VALUES (2, 2, 3);

  • writing terminal output to file

    - by user1551817
    On my machine, I have some software which takes commands in the terminal and returns a list of values. To run it, I have to type something like: pdv -t filename I am trying to run it as part of a python programme. When I run the following: os.system('pdv -t %s' % (epoch_name)) then I get the values that I desire returned to my terminal (where epoch_name is the variable name for the filename). But when I try to write the result to a file: os.system('pdv -t %s % "(epoch_name)" > 123.txt') the file 123.txt is produced but it is empty. I know that I am misplacing the " and/or ' characters, but I can't figure out where they should go. Any help would be gratefully received!

  • ASP.net PreInit() Vs Init()

    - by ASP.netBeginner
    From local forum i understood that PreInit can be used to handle the following PreInit() >Master pages can be called dynamically >Themes can be set dynamically >Programatically add controls to controls collection and i read Init() is for Init() In this event, we can read the controls properties (set at design time). We cannot read control values changed by the user because that changed value will get loaded after LoadPostData() event fires. Question I am not getting the point "We cannot read control values changed by the user".Where do users change the value of control?.Example would help me to understand the point.

  • how-to initialize 'const std::vector<T>' like a c array

    - by vscharf
    Is there an elegant way to create and initialize a const std::vector<const T> like const T a[] = { ... } to a fixed (and small) number of values? I need to call a function frequently which expects a vector<T>, but these values will never change in my case. In principle I thought of something like namespace { const std::vector<const T> v(??); } since v won't be used outside of this compilation unit.
