  • Changing function parameters for onkeypress event according to source id

    - by DarRay
    I want to assign a function according to their id to all the input fields in a webpage. To do i wrote below code but all the input fields are running keyPress with same parameter.. :( ///////////////////Checks all available 'text' 'input's//////////////////// var inputs = document.getElementsByTagName('input'); var cnvtrInput = new Array(); for (var index = 0; index < inputs.length; index++) { if (inputs[index].type == 'text') { cnvtrInput[index] = new converter(inputs[index]); inputs[index].onkeypress = function() {return keyPess(cnvtrInput[index])}; } } //index--; With the last commented statement i found that the passing element of keyPress is the last value of index; Finally i tried same with textareas but failed...

  • Write a function in c that includes the following sequence of statements [Wont Compile]

    - by Cody
    There is a question in my programming languages textbook that is as follows: Write a C function that includes the following sequence of statements: x = 21; int x; x = 42; Run the program and explain the results. Rewrite the same code in C++ and Java and compare the results. I have written code, and played with it in all three languages but I can not even get it to compile. This includes declaring x above the three lines as well as in the calling function (as this question is obviously attempting to illustrate scoping issues) I'd like to explain the results and do the comparisons on my own, as it is an assignment question but I was wondering if anyone had any insight as to how to get this code to compile? Thanks

  • While loop within Javascript function

    - by JM4
    I have the following basic function: <script type="text/javascript"> function Form_Data(theForm) { var t=1; while (t<=5) { if (theForm.F[t]FirstName.value == "") { alert("Please enter Fighter 1's First Name."); theForm.F[t]FirstName.focus(); return (false); } t++; } return (true); } </script> The script (js validation) fails using this code. If I remove the [t] and replace with a number (1,2,3,4,etc), the validation works on the appropriate fields. What am I doing wrong?

  • Jquery click function does not load ajax tabs

    - by user342391
    I have some tabs that load ajax content. When I click on the tabs it loads the ajax content perfectly no issues works exactly like it does in the Jqueryui demos. But when I try and change tab using an onclick function it opens the tab but doesn't do the ajax. Is this a known issue can it be done?? Do ajax tabs rely on the user clicking the href to know what to load. This is the code: $(".step2next").click(function() $('#signuptabs').tabs("select" , 1));

  • Custom SQL function for NHibernate dialect

    - by Kristoffer Ahl
    I want to be able to call a custom function called "recent_date" as part of my HQL. Like this: [Date] >= recent_date() I created a new dialect, inheriting from MsSql2000Dialect and specified the dialect for my configuration. public class NordicMsSql2000Dialect : MsSql2000Dialect { public NordicMsSql2000Dialect() { RegisterFunction( "recent_date", new SQLFunctionTemplate( NHibernateUtil.Date, "dateadd(day, -15, getdate())" ) ); } } var configuration = Fluently.Configure() .Database( MsSqlConfiguration.MsSql2000 .ConnectionString(c => .... ) .Cache(c => c.UseQueryCache().ProviderClass<HashtableCacheProvider>()) .Dialect<NordicMsSql2000Dialect>() ) .Mappings(m => ....) .BuildConfiguration(); When calling recent_date() I get the following error: System.Data.SqlClient.SqlException: 'recent_date' is not a recognized function name I'm using it in a where statement for a HasMany-mapping like below. HasMany(x => x.RecentValues) .Access.CamelCaseField(Prefix.Underscore) .Cascade.SaveUpdate() .Where("Date >= recent_date()"); What am I missing here?

  • JNI: Passing multiple parameters in the function signature for GetMethodID

    - by Jary
    I am trying to execute a function in Java (from C) that has the following signature: public void execute(int x, int y, int action); My problem is to define the function signature in GetMethodID: env->GetMethodID(hostClass, "execute", "(I;I;I;)V"); The problem I ma getting is: W/dalvikvm( 1849): Bogus method descriptor: (I;I;I;)V W/dalvikvm( 1849): Bogus method descriptor: (I;I;I;)V D/dalvikvm( 1849): GetMethodID: method not found: Lcom/device/client/HostConnection;.execute:(I;I;I;)V I am not sure how to specify the method signature in GetMethodID (for 3 integers as parameters). I saw people use the ";" to separate parameters in other posts for the String and File class, but nothing with primitives like integer. What would be the correct way to do this please? Thank you.

  • php mail function cannot send to [email protected] ??i

    - by user333216
    I'm having trouble when sending emails thorough the mail() function. I have a script that works perfectly fine for an email address like [email protected] but when the first part of the email is something with a dot like [email protected] it doesn't work and returns this error : Warning: mail() [function.mail ]: SMTP server response: 554 : Recipient address rejected: Relay access denied in confirmed.php on line 119 I am using real email address but have changed it in the above example. Any thoughts - I'm not a php master but surely there is an easy way to send emails to address with a 2 part first section?? Thanks in advance Ali

  • Forked Function not assigning pointer

    - by Luke Mcneice
    In the code below I have a function int GetTempString(char Query[]); calling it in main works fine. However, when calling the function from a fork the fork hangs (stops running, no errors, no output) before this line: pch = strtok (Query," ,"); the printf shows that the pointer to pch is null. Again this only happens when the fork is executing it. What am I doing doing wrong? int main() { if((Timer =fork())==-1) printf("Timer Fork Failed"); else if(Timer==0) { while(1) { sleep(2); GetTempString("ch 1,2,3,4"); } } else { //CODE GetTempString("ch 1,2,3,4"); } } int GetTempString(char Query[]) { char * pch; printf("DEBUG: '%s'-'%d'\n",Query,pch); pch = strtok (Query," ,");//* PROBLEM HERE* //while loop for strtok... return 1; }

  • Force external function to be const

    - by vanna
    Here is my problem. I made a class with a member function declared as const that uses an external function that I cannot modify (declared in someone else's code) and that is not declared const. More precisely Someone else's code class B { public: void foo(); }; My code class A : public B { public: void bar() const { this->foo(); } }; I know that for member data we can force const-correctness by using mutable or const_cast. How can I 'hack' foo such that my compiler understands that I would like to use it as if it was const even if it is not declared in someone else's code ?

  • Haskell: Pattern Matching with Lists

    - by user1670032
    I'm trying to make a function that takes in a list, and if one of the elements is negative, then any elements in that list that are equal to its positive counterpart should be changed to 0. Eg, if there is a -2 in a list, then all 2's in that list should be changed to 0. Any ideas why it only works for some cases and not others? I'm not understanding why this is, I've looked it over several times. changeToZero [] = [] changeToZero [x] = [x] changeToZero (x:zs:y:ws) | (x < 0) && ((-1)*(x) == y) = x : zs : 0 : changeToZero ws changeToZero (x:xs) = x : changeToZero xs *Main changeToZero [-1,1,-2,2,-3,3] [-1,1,-2,2,-3,3] *Main changeToZero [-2,1,2,3] [-2,1,0,3] *Main changeToZero [-2,1,2,3,2] [-2,1,0,3,2] *Main changeToZero [1,-2,2,2,1] [1,-2,2,0,1]

  • The function of service principal names in Active Directory

    - by boxerbucks
    I am thinking about taking a service that runs on multiple servers in my domain currently as "NETWORK SERVICE" and configuring it to run as an AD domain account for various reasons. If I have this one account running the same service under multiple servers, do I need to create SPN's for each of the machines and services it runs? Would I need to worry about creating SPN's at all? If the answer is no, then what is the proper role of an SPN?

I am trying to access the value of getArr%a(1) as: double precision function my_func(R) use getArr double precision x x = getArr%a(1) return end But I am getting errors at the compile time. It says it is unable to access the module getArr. How should I declare it?? Thanks

Can anyone suggest something which works for both IE and Mozilla?

  • [PHP] strtr function OS-reltated problem

    - by Casidiablo
    Hello there! I have this funtion that converts all special chars to uppercase: function uc_latin1($str) { if(!defined("LATIN1_UC_CHARS")) define("LATIN1_UC_CHARS", "ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝ"); if(!defined("LATIN1_LC_CHARS")) define("LATIN1_LC_CHARS", "àáâãäåæçèéêëìíîïðñòóôõöøùúûüý"); $str = strtoupper ( strtr ( $str, LATIN1_LC_CHARS, LATIN1_UC_CHARS ) ); return $str; } This function works fine in my development PC (which runs Windows XP)... but, when I test it in the production server (running Redhat Linux) it does not uppercase the string. The string is ISO-8859-1 encoded. How can I make it work in Linux too? Thanks for reading.
