  • How to style just one type of input field without also affecting other input types with CSS

    - by James
    Is there a way to write style rules that will only influence text fields. Suppose I have the following: <div id="helloDiv"> <input type="text" name="something" /><br /> <input type="checkbox" name="somethingElse" /><br /> <input type="submit" name="go" /> </div> div#helloDiv input { border: 1px solid red; } The problem with the above CSS rule is that it will affect ALL input fields not just input text but also radio buttons, submit buttons, etc. So is there a cross browser solution to affect just one type of input field within a div or other page element (without resorting to assigning the input fields styles individually).

  • Alternatives to sign() in sqlite for custom order by

    - by Pentium10
    I have a string column which contains some numeric fields, but a lot are 0, empty string or null. The rest are numbers having different range, all positive. I tried to create a custom order by. The order would be done by two fields. First I would like to order the fields that have this number 0 and then sort by name. So something this would work: select * from table order by sign(referenceid) desc, name asc; But Sqlite lacks the sign() -1/0/1 function, and I am on Android and I can't create user defined functions. What other options I have to get this sort done.

  • Import Data from Excel Spreadsheet or CVS into MySQL

    - by Kelly Roper
    I have a spreadsheet which really has only one complicated table. I basically convert the spreadsheet to a cvs and use a groovy script to generate the INSERT scripts. However, I cannot do this with a table that has 28 fields with data within some of the fields on the spreadsheet that make importing into the CVS even more complicated. So the fields in the new CVS are not differentiated properly or my script has not accounted for it. Does anyone have any suggestions on a better approach to do this? Thanks.

  • JNAerator Unnamed Union Missing in Structure

    - by Nick
    I'm trying to get JNAerator to generate some JNA backed Java code from a C shared library and everything is fine except that it failed to generate an unnamed union nested inside a structure. Example: typedef struct MY_STRUCTURE { union { My_Type1 var1; My_Type2 var2; }; }MY_STRUCTURE; If I change the header to make the union have a name it will work. But for obvious reasons I can't just change the header without breaking the shared library I'm trying to use. Any solutions other than changing the header file and shared library to named union?

  • SQL validation!

    - by Filip
    I am pretty new in SQL so this may be a stupid question... I have a form in PHP which fills in few fields in my SQL table. I have this code: $sql="INSERT INTO $tbl_name (app_name, app_path, short_desc, full_desc) VALUES ('$_POST[app_name]', '$_POST[app_path]', '$_POST[short_desc]', '$_POST[full_desc]')"; But even app_name and app_path are NOT NULL columns, the query can be executed if there is no text in these fields in the form. So, my question is: How to stop the execution of the query if there is no text in the NOT NULL fields ?

  • How to use $.get data to replace certain elements in a webpage?

    - by Jack Ha
    I'm using jQuery 1.4.2 to navigate smoothly between similar webpages (in ff3). When clicking on a link, a javascript script should load the new html, filter out the right elements and replace them on the current page. It looks like the $(htmlcode) does not do the thing I expected. The actions below work when loading the page directly, but when using the $.get I have the following problems: the find function seems only to look inside a div element called id="page", which is inside the body element one of the elements has <script>...</script>, but the <script>...</script> is not present in the DOM of $(htmlcode). Anybody knows how to solve this? $.get( url, function(responseText, textStatus, xmlHttpRequest) { alert($(responseText).find("#header")); // works, #header is inside div#page alert($(responseText).find("#header").html()); // displays content, but WITHOUT the <script>...</script> alert($(responseText).find("title")); // does not work, title is outside div#page } );

  • strange behaviour of static method

    - by Cristian Boariu
    Hi, I load a js variable like this: var message = '<%= CAnunturi.CPLATA_RAMBURS_INFO %>'; where the static string CPLATA_RAMBURS_INFO i put like: public static string CPLATA_RAMBURS_INFO = "test"; I use it very well in this method. <script type="text/javascript"> var categoryParam = '<%= CQueryStringParameters.CATEGORY %>'; var subcategoryParam = '<%= CQueryStringParameters.SUBCATEGORY1_ID %>'; var message = '<%= CAnunturi.CPLATA_RAMBURS_INFO %>'; function timedInfo(header) { $.jGrowl(message, { header: header }); }; </script> so the message appears. I do not undersand, why, iso of "test", if i take the value from a static method, ths use of message js var is no longer succesfull (the message no longer appears). public static string CPLATA_RAMBURS_INFO = getRambursInfo(); public static string getRambursInfo() { return System.IO.File.ReadAllText(PathsUtil.getRambursPlataFilePath()); } Any help would be highly appreciated....

  • Can I use Cassandra to store objects?

  • How to Create C++ Project Filter/Folder in Visual Studio?

    - by BSalita
    Using Visual Studio 2012, I'd like to create a C++ project folder called "Include Files", which has the same characteristics as the well known folder "Header Files". That is, the files in Include Files have a cpi extenson and will be parsed out for use with InteliSense, and also can be precompiled. I'm able to create the folder but files within it aren't parsed. I've tried setting the type to C++ Header file. Nothing seems to work. The files work fine when given a hpp extension and put into Header Files folder.

  • SQL Query: Using IF statement in defining new field

    - by Tofig Hasanov
    I have a table with many fields and additionally several boolean fields (ex: BField1, BField2, BField3 etc.). I need to make a Select Query, which will select all fields except for boolean ones, and a new virtual field (ex: FirstTrueBool) whose value will equal to the name of the first TRUE Boolean Field. For ex: Say I have BField1 = False, BField2 = True, BField3 = true, BField4=false, in that case SQL Query should set [FirstTrueBool] to "BField2". Is that possible? Thank you in advance. P.S. I use Microsoft Access (MDB) Database and Jet Engine.

  • MySQL Rating system (calculating average from two tables).

    - by MussuR
    I have two tables, videos and videos_ratings. The videos table has an int videoid field (and many others but those fields are not important I think) and many records. The videos_ratings table has 3 int fields: videoid, rating, rated_by which has many records (multiple records for each fields from the videos table) but not for all records from the videos table. Currently I have the following mysql query: SELECT `videos`.*, avg(`videos_ratings`.`vote`) FROM `videos`, `videos_ratings` WHERE `videos_ratings`.`videoid` = `videos`.`videoid` GROUP BY `videos_ratings`.`videoid` ORDER BY RAND() LIMIT 0, 12 It selects all the records from table videos that have a rating in table video_ratings and calculates the average correctly. But what I need is to select all records from the videos table, no matter if there is a rating for that record or not. And if there aren't any records in the videos_ratings table for that particular videos record, the average function should show 0. Hope someone could understand what I want... :) Thanks!

  • Gridview inside UpdatePanel refresh

    - by Attilah
    I use a GridView to represent data from a table in my DB. the GridView has some template fields whose content are determined before displaying the Grid ( I use the RowDataBound event to determine content of template fields before displaying the GridView). The page displays a list of records from the table records and then, the recording process starts. after the process is over, the template fields should be updated. how do I automatically refresh the GridView after the process is finished ? it should be noted that the GridView is contained within an control and that I continuously poll the server using a Timer control that executes "GridView1.DataBind()" at the server level every 60 seconds. since the GridView is inside an UpdatePanel, calling DataBind() method on it doesn't seem to call the RowDataBound event. How can I solve this ?

  • Function defined but not used warning in C

    - by thetna
    I have a number of C source files(both .c and .h files). header files contains a number of functions. Out of those functions, only partially are used in a source .C file.Suppose a.h,b.h are header files and a.c and b.c are .c files. a.h is included in a.c. But only a number of functions those are in a. h are used and rest are not used. After compilation I find following warnings: function XXXX defined but not used. But those XXXX functions which are not used in a.c are used in b.c. So, i can't completely remove those functions too. So , i decided to make a separate file containing only those XXXX functions and included it wherever it is used.Doing this is creating multiple number of header files. Can anybody please suggest me to some effective way to solve this problem.

  • What is the proper way to check the previous value of a field before saving an object? (Using Django

    - by anonymous coward
    I have a Django Model with updated_by and an approved_by fields, both are ForeignKey fields to the built-in (auth) User models. I am aware that with updated_by, it's easy enough to simply over-ride the .save() method on the Model, and shove the request.user in that field before saving. However, for approved_by, this field should only ever be filled in when a related field (date_approved) is first filled in. I'm somewhat certain that I can check this logically, and fill in the field if the previous value was empty. What is the proper way to check the previous value of a field before saving an object? I do not anticipate that date_approved will ever be changed or updated, nor should there be any reason to ever update the approved_by entry. UPDATE: Regarding forms/validation, I should have mentioned that none of the fields in question are seen by or editable by users of the site. If I have misunderstood, I'm sorry, but I'm not sure how forms and validation apply to my question.

  • Defining a static array into a C or C++ source file.

    - by VansFannel
    Hello. I know this is a question that every programmer should know, but I do not know. Long time no C programming and I've forgotten a lot of things. My question is: I have three huge static arrays defined inside a header file. Someone told me that It's much better to declare them as extern in the header file, and define them in a single C or C++ source file. How can I do that? Here is my header file: #ifndef _TEMPLE_OBJECT_H_ #define _TEMPLE_OBJECT_H_ #define NUM_TEMPLE_OBJECT_VERTEX 10818 static const float TEMPLEVertices[NUM_TEMPLE_OBJECT_VERTEX * 3] = {...}; static const float TEMPLENormals[NUM_TEMPLE_OBJECT_VERTEX * 3] = {...}; static const float TEMPLETexCoords[NUM_TEMPLE_OBJECT_VERTEX * 3] = {...}; #endif If a use a C++ source file, may I need to define a class? Thank you.

  • How do I make a multiple file upload?

    - by Bluemagica
    I am trying to make a multiple image uploader. The file upload fields are being added in the form dynamically using jquery. I tried making an array of the fields since I don't want to have a hidden field. so my generated upload fields look like <input type="file" id="img0" name="img[]"/> <input type="file" id="img1" name="img[]"/> <input type="file" id="img2" name="img[]"/> ..... .. And on the php side I did something like if(isset($_FILES['img'])) { foreach($_FILES['img'] as $k=>$v) { if($v!="") { uploadImage($k,0,0,0,"content/gallery/"); } } } Now I know I am way too wrong, since in that code I am looping through the 'img' file's properties instead of all images....but I have no idea how to fix this. PS: uploadImage is a function I wrote which expects the file input field's name as the first parameter.

  • SWIG interface file questions

    - by morpheous
    I am writing a C/C++ extension module for other languages and I am using SWIG to generate the bindings. I have two questions Can I include more than 1 header file in the declaration part of the interface file e.g.: /* Declarations exposed to wrapper: */ > %{ > #define SWIG_FILE_WITH_INIT > #include "a.h" > #include "b.h" > #include "c.h" %} In all of the examples I have seen so far, after the header include declaration (as shown above), the functions declared in the header are then declared again in the interface file. Is this really necessary, as it means there are two copies of the function declarations that need to be maintained. Note: I can appreciate that some functions/methods declaration may need to be 'decorated' with the 'newobject' declaration so these obviously need to be in the interface file, to avoid memory leaks - however, I would have though that it would be sufficient to include the headers and then ONLY the declarations of the functions/methods that need to be declared with 'newobject' - is this recommended way of doing things?

  • How to make large List & Label template?

    - by codymanix
    We want to have a form which contains lots of fields one over another. All of them are passed as parameters to the form. There are many condition formulas which determine whether one element is shown or not. Depending on how many fields are shown the result will get a different number of pages. The problem is, that the designer will only allow us to design on on single page with a fixed height. But we need more space to place fields there, because they are too many of them. Is there a way to enlarge the designer working area? Sure, a possible workaround is to choose a large paper format when in dessiger which will enlarge the working area and then reset it to A4 (Standard paper format), but even this will not be enough for us in some cases. Does nobody know an answer?

  • C: theory on how to extract files from an archived file

    - by donok
    In C I have created a program which can archive multiple files into an archive file via the command line. e.g. $echo 'file1/2' > file1/2.txt $./archive file1.txt file2.txt arhivedfile $cat archivedfile file1 file2 How do I create a process so that in my archivedfile I have: header file1 end header file2 end They are all stored in the archive file one after another after another. I know that perhaps a header file is needed(containing filename, size of filename, start and end of file) for extracting these files back out into their original form, but how would I go about doing this. I am stuck on where and how to start. Please could someone help me on some logic as to how to approach extracting files back out of an archived file.
