  • How can I write a power function myself?

    - by Koning WWWWWWWWWWWWWWWWWWWWWWW
    Since I was 12, I was always wondering how I can make a function which calculates the power (e.g. 23) myself. In most languages these are included in the standard library, mostly as pow(double x, double y), but how can I write it myself? I was thinking about for loops, but it think my brain got in a loop (when I wanted to do a power with a non-integer exponent, like 54.5 or negatives 2-21) and I went crazy ;) So, how can I write a function which calculates the power of a real number? Thanks

  • WPF/C#: How to simplify the use of codes when calling a function (Generating Images)

    - by eibhrum
    I created a function in one of my application that allows to generate an image (in WPF) by getting the 'source path' from the database that I am using: public void ShowImageThumb() { try { cn = new MySqlConnection(); cn.ConnectionString = ConfigurationManager.AppSettings["MyConnection"]; cn.Open(); MySqlCommand cmd = new MySqlCommand(); cmd.Connection = cn; cmd.CommandType = CommandType.Text; cmd.CommandText = "SELECT thumb FROM album WHERE thumbNo=1"; MySqlDataAdapter adp = new MySqlDataAdapter(); adp.SelectCommand = cmd; DataTable dt = new DataTable(); adp.Fill(dt); MySqlDataReader r = cmd.ExecuteReader(); while (r.Read()) { BitmapImage bmi1 = new BitmapImage(new Uri(r[0].ToString(), UriKind.Relative)); image1.Source = bmi1; } r.Close(); cn.Close(); } catch (Exception err){ System.Windows.MessageBox.Show(err.Message); } finally { } } Take a look on my SQL statement. I put a WHERE thumbNo=1 which allows the function to get 1 record. You see, I do have at least 10 records - file paths listed in that table. I just wanna ask if there's a possible way to make my SQL statement something like this: SELECT thumb FROM album; while having this piece of code inserted in my function: BitmapImage bmi2 = new BitmapImage(new Uri(r["second record?"].ToString(), UriKind.Relative)); image2.Source = bmi2; //something like this BitmapImage bmi3 = new BitmapImage(new Uri(r["third record?"].ToString(), UriKind.Relative)); image3.Source = bmi3; //something like this and so on and so forth, without ending up creating 10 different functions for 10 records. ShowImageThumb2(); . . // will not do this . ShowImageThumb10(); Sorry for the lengthy post. I hope somebody could answer back. Thanks!

  • Arrays become null after passing to function in PHP

    - by William
    So when I pass my filled arrays to the function createform the form is created with $max_avatars options, but they have no name or value. Why are my arrays becoming null? <?php $avatar_image_name = array('hacker','samurai','cool','happy','thatsnice','angry','tv','bang'); $avatar_name = array('Hacker','Samurai','Cool','Happy','That\'s nice','Angry','TV','Bang'); $max_avatars = 6; createform($max_avatars, $avatar_image_name, $avatar_name); ?> The function createform: function createform($max_avatars, $avatar_image_name, $avatar_name) { $string ='<table id="formtable"> <tr><td class="formtext">Name:</td><td><input type="text" name=name size=25 /></td></tr> <tr><td class="formtext">Trip:</td><td><input type="text" name=trip size=25 /> (<font style="color: #ff0000">Don\'t use your password</font>)</td></tr> <tr><td class="formtext">Comment</td><td><textarea name=post rows="4" cols="50"></textarea></td></tr> <tr><td class="formtext">Avatar:</td> <td> <select name=avatar>'; for($i = 0; $i < $max_avatars; $i++){ $string = ($string .

  • Keyboard doesn't function after Fedora 17 update

    - by mickburkejnr
    I updated my Fedora 16 installation to Fedora 17 on Saturday, and the update worked without reporting any errors. I carried on working on the machine in question and then switched the computer off. Last night I went back on the computer, I switched it on and got to the log in screen. At this point I tried to type in my password but the keyboard wouldn't work. I unplugged it (it's a PS/2 keyboard) and plugged it back in. The lights flashed for a split second but the keyboard still wouldn't work. I then plugged the keybaord in to a USB to PS/2 adapter, and the keyboard still wouldn't work. I restarted the computer and tried to access the BIOS and I was able to do so. So the keyboard doesn't seem to be faulty, it just doesn't work when Fedora boots in to the GUI interface. I did try to boot in to the "recovery mode" of Fedora, and the keyboard works here with no problem. As I still have access to Fedora via a terminal interface, is there anything I can do to fix the keyboard problem via the terminal without having to reinstall Fedora?

  • how to invoke function writen in a validation.php and stroe all function name in database.

    - by saint
    Respected all, i'm in trouble. I created a file with name validation.php and store all my validation functionality in this file with different function names like, check_textbox(parm1, pram2, pram3, pram4) { // Definition here } check_chkBox(parm1, pram2) { // Definition here } and so on.....! then i created a table in mysql with the name tbValidation and stored all the function name with parameters in a table. the record stored in table look like as: interfaceid---------- functionNameWithReturnValue 1 ------------ check_textbox(parm1, pram2, pram3, pram4) = 1 2 ------------ check_textbox(parm1, pram2, pram4) = 0 3 ------------ check_textbox(parm1, pram2, pram4) = 1) AND (check_chkBox(parm1, pram2)=0) when i fetch record from database i want to invoke those functions that store in validation.php $data = mysql_fetch_array($drow); if($db->row_count > 0) { // when i fetch row one from database. I used this one but not working // @ $data[0] have value "check_textbox(parm1, pram2, pram3, pram4) = 1" if($data[0]) { // Do this } } How i can do this task...? :(

  • Is this call to a function object inlined?

    - by dehmann
    In the following code, Foo::add calls a function via a function object: struct Plus { inline int operator()(int x, int y) const { return x + y; } }; template<class Fct> struct Foo { Fct fct; Foo(Fct f) : fct(f) {} inline int add(int x, int y) { return fct(x,y); // same efficiency adding directly? } }; Is this the same efficiency as calling x+y directly in Foo::add? In other words, does the compiler typically directly replace fct(x,y) with the actual call, inlining the code, when compiling with optimizations enabled?

  • Passing Variables Along in a Function

    - by John
    Hello, In the function show_commentbox() below, I would like to pass along the variables $_SESSION['loginid'], $submissionid, $submission, $url, $submittor, $submissiondate, $countcomments, $dispurl. With the setup below, it's not working. How could I change it to make show_commentbox() pass the variables along?

  • return false for parent javascript function

    - by jeerose
    $("#purchaser_contact").live('submit', function(){ $.ajax({ type: "POST", url: 'ajax/contactSearch.php', data: ({ fname: $("#fname").val(), lname: $("#lname").val(), city: $("#city").val(), state: $("#state").val() }), success: function(d) { var obj = JSON.parse( d ); if(obj.result != 0){ $("#contactSearch").remove(); $("#button-wrapper").before('<div id="contactSearch">' + obj.result + '</div>'); $("#contactSearch").slideToggle('slow'); //return false from submit!! }); }); I know there are other posts on this but I couldn't figure out how to apply them properly to my situation without making it messy. How do I return false on the submit event to prevent the form from submitting if I'm within the $.ajax and success functions? Thanks.

  • MYSQL: How do I set a date (makedate?) with month, day, and year

    - by chongman
    Hi? I have three columns, y, m, and d (year, month, and day) and want to store this as a date. What function would I use on mySQL to do this? Apparently makedate uses year and day of year (see below), but I have month. I know I can use STR_TO_DATE(str,format), by constructing the string from (y,m,d), but I would guess there is an easier way to do it. REFERENCES MAKEDATE(year,dayofyear) Returns a date, given year and day-of-year values. dayofyear must be greater than 0 or the result is NULL.

  • preg_replace pass match through function before replacing

    - by Martin
    This is what i want to do: $line = 'blabla translate("test") blabla'; $line = preg_replace("/(.*?)translate\((.*?)\)(.*?)/","$1".translate("$2")."$3",$line); So the result should be that translate("test") is replaced with the translation of "test". The problem is that translate("$2") passes the string "$2" to the translate function. So translate() tries to translate "$2" instead of "test". Is there some way to pass the value of the match to a function before replacing?

  • jquery onclick function not firing with rails link_to_remote

    - by RahTha
    In the js file of the page, inside $(document).ready(function() {} i have $(".school a").live("click", function (e){ e.preventDefault(); ....; jsFunc(param1, param2, param3); }); Now the div with the class school has tags generated by rails link_to_remote with :url, :action, :before, :html. On clicking on this link it does all that it should do with regards to link_to_remote, but somehow the onclick event in the document.ready does not attach to it. Why would this be happening? The jsFunc all it does is post to a url async-ly, i figured out that stuffing that post url in the :before of the link_to_remote would work - but is there a more elegant way of just being able to use the attach functionality

  • View a SYS.XMLTYPE returned from an Oracle function, using PL/SQL

    - by caerphilly
    I have an Oracle function that dynamically creates an XML document, and returns it in a SYS.XMLTYPE value. I want to run a query from SQL Developer that calls that function and prints the document (either via a select, or dbms_output - I don't care). But all the examples/documentation seem to refer to querying XML columns in tables, and I can't seem to get the syntax right for my particular usage. I'd like something like this: declare x SYS.XMLTYPE; begin x := my_package.my_function(); select x.getclobval() from x; -- doesn't work! end; How can I print out the value of the XML type variable 'x' in the above code?

  • Jquery: syntax for inserting a function

    - by kelly
    I'm trying to integrate an animation by using the bezier path plug-in and I can't seem to implement it right. Stripped down, here's what I have: $('#next2btn').live('click', function(){ $(this).attr('id','next3btn'); $('#content2').show(300, function() { $('#account').fadeTo(500,1.0) var arc_params = { center: [278,120], radius: 186, start: -90, end: 90, dir: -1 }; }); $("#account").animate({path : new $.path.arc(arc_params)},1000); }); So, I'm trying to add this piece of code into what I have: var arc_params = { center: [278,120], radius: 186, start: -90, end: 90, dir: -1 }; }); $("#account").animate({path : new $.path.arc(arc_params)},1000) which works on its own as does the other. I'm thinking it's something about declaring that variable and where I do that. I'm essentially chaining a few different animations/actions upon a button click. Thanks for any insight- kj

  • Compiler error when casting to function pointer

    - by detly
    I'm writing a bootloader for the PIC32MX, using HiTech's PICC32 compiler (similar to C90). At some point I need to jump to the real main routine, so somewhere in the bootloader I have void (*user_main) (void); user_main = (void (*) (void)) 0x9D003000; user_main(); (Note that in the actual code, the function signature is typedef'd and the address is a macro.) I would rather calculate that (virtual) address from the physical address, and have something like: void (*user_main) (void); user_main = (void (*) (void)) (0x1D003000 | 0x80000000); user_main(); ...but when I try that I get a compiler error: Error #474: ; 0: no psect specified for function variable/argument allocation Have I tripped over some vagarity of C syntax here? This error doesn't reference any particular line, but if I comment out the user_main() call, it goes away. (This might be the compiler removing a redundant code branch, but the HiTech PICC32 isn't particularly smart in Lite mode, so maybe not.)

  • Why is one Func valid and the other (almost identical) not.

    - by runrunraygun
    private static Dictionary<Type, Func<string, object>> _parseActions = new Dictionary<Type, Func<string, object>> { { typeof(bool), value => {Convert.ToBoolean(value) ;}} }; The above gives an error Error 14 Not all code paths return a value in lambda expression of type 'System.Func<string,object>' However this below is ok. private static Dictionary<Type, Func<string, object>> _parseActions = new Dictionary<Type, Func<string, object>> { { typeof(bool), value => Convert.ToBoolean(value) } }; I don't understand the difference between the two. I thought the extra braces in example1 are to allow us to use multiple lines in the anon function so why have they affected the meaning of the code?

  • Function testing on Netbeans 6.8

    - by ron
    While not a torrent, but some articles can be found on the net about function testing (particularly http://blogs.sun.com/geertjan/entry/gui_testing_on_the_netbeans). However the tools mentioned by them do not seem to be maintained, or don't have a plugin working with the most recent version of Netbeans (6.8). Do you have any function test setup for GUI? What is your level of integration into the development process (IDE integration, ant, etc). Additional candy is that Netbeans is not only the IDE, but the GUI app is also developed for Netbeans 6.8 Platform (so I'm mainly interested in GUI testing NB-platform apps, but tips for any Swing apps in general would be a help too).

  • Difficulty creating a paging function with MySQL and ColdFusion

    - by Mel
    I'm trying to create pagination for search results using MySQL and ColdFusion. My intention is to only retrieve the queries that can be displayed on a single page, thus making the process efficient. I tried using two queries in my function, but I could not return two variables to the cfinvoke. The following code does not paginate, but it displays the result search results using a CFC: <!---DEFINE DEFAULT STATE---> <cfparam name="variables.searchResponse" default=""> <cfparam name="URL.titleName" default=""> <cfparam name="URL.genreID" default=""> <cfparam name="URL.platformID" default=""> <!---TitleName can only be blank if one or both genre and platform are selected---> <cfif StructKeyExists(URL, "searchQuery") AND (Len(Trim(URL.titleName)) LTE 2 AND Len(URL.genreID) IS 0 AND Len(URL.platformID) IS 0)> <cfset variables.searchResponse = "invalidString"> <cfelseif StructKeyExists(URL, "searchQuery")> <cfinvoke component="gz.cfcomp.test" method="searchGames" returnvariable="resultData" argumentcollection="#URL#"> <cfset variables.searchResponse = "hasResult"> </cfif> <cfif searchResponse EQ "hasResult" AND resultData.RecordCount EQ 0> <cfset variables.searchResponse = "noResult"> </cfif> Using this logic, I can display what I need to display on the page: <cfif searchResponse EQ "invalidString"> <cfoutput>Invalid search</cfoutput> </cfif> <cfif searchResponse EQ "noResult"> <cfoutput>No results found</cfoutput> </cfif> <cfif searchResponse EQ "hasResult"> <cfoutput>Display Results</cfoutput> </cfif> If I were executing the queries on the same page, it would be easy to follow the many tutorials out there. But the queries are executing in a function. Displaying the data is easy, but paginating it has become a nightmare for me. Here is my function: <cffunction name="searchGames" access="public" output="false"> <cfargument name="titleName" required="no" type="string"> <cfargument name="genreID" required="no" type="string"> <cfargument name="platformID" required="no" type="string"> <!--- DEFINE LOCAL VARIABLES---> <cfset var resultData = ""> <!---GET DATA---> <cfquery name="resultData" datasource="myDSN"> SELECT * <!---JOINS FOR GENRE/PLATFORM GO HERE---> WHERE <!---CONDITIONS GO HERE---> </cfquery> <!---RETURN VARIABLE---> <cfreturn resultData> </cffunction> To paginate, I thought about modifying my function to the following (a new query using a count statement): <!--- DEFINE LOCAL VARIABLES---> <cfset var resultCount = ""> <!---GET DATA---> <cfquery name="resultCount" datasource="myDSN"> SELECT COUNT(gameID) AS rowsFound FROM GAMES <!---JOINS FOR GENRE/PLATFORM GO HERE---> WHERE <!---CONDITIONS GO HERE---> </cfquery> <!---RETURN VARIABLE---> <cfreturn resultCount> Then I figured if there is a result to return, I would execute a nested query and create the pagination variables: <cfif resultCount.rowsFound GTE 0> <cfparam name="pageNumber" default="1"> <cfset var recordsPerPage = 5> <cfset var numberOfPages = Int(resultCount.RecordCount / recordsPerPage)> <cfset var recordsToSkip = pageNumber * recordsPerPage - recordsPerPage> <!---DEFINE LOCAL VARIABLE---> <cfset var resultData = ""> <cfquery name="resultData" datasource="myDSN"> <!---GET DATA AND SEND IT BACK USING LIMIT WITH #recordsToSkip# and #RecordsPerPage#---> </cfquery> <!---RETURN VARIABLE---> <cfreturn resultData> </cffunction> I figured I would return two variables: resultCount and resultData. I would use #resultCount# to build my pagination, and #resultData# to display the output. The problem is I can't return two variables in the same cfinvoke tag. Any ideas of how to approach the the right way? I'm totally lost as to the logic I need to follow.
