• filter search results with another form

  - by Ygam

  so here's the problem I have one form, it outputs search results after submit, with this URL http://localhost/thi/search/results?keyword=barma&search=1&minprice=nomin&maxprice=nomax&minroom=nomin&maxroom=nomax&minyear=nomin&maxyear=2010 Now I have another form, which is supposed to filter the results from the previous form by getting the current url of the search results and appending to it the GET variables submitted by this form. I tried filtering before, but that is with anchor links. How am I supposed to do it with forms? Anny approaches?

• a variable in HTML

  - by PurplePilot

  in the form action i have the following line\ <form action="{URL}" method="post" target="_self" id="xxx" name="xxx"> when rendered in the browser it becomes action="/abc/17224_pb/HTTP/index.php" this is just HTML. I cannot see anywhere the {URL} has been defined and anyway you cannot have variables in HTML (can you?) i thought it might be jquery but it would need to be in a script ?? Where does it come from? How is it defined? This code is not really in a framework but we do have some Zend framework code around.

• Issue in exec method

  - by mukul sharma

  Hi all, I am a having two python files file1.py and file2.py. I am using exec() to get the method/Variables defined in the file2.py. file1.py have a class as given below class one: def init(self): self.HOOK = None exec(file2.py) self.HOOK = Generate ### call the hook method #### self.HOOK() file2.py looks like as (There is no class define in file2.py) def Generate() do 1 do 2 Hello() def hello() print "hello" Now the problem is as When i run script it is giving a error global name Hello not found. If i remove Hello() from Generate method in file2.py then its work fine. I cant use import file2.py in file1.py,because in file2.py the only one method name (Generate) is fix (its taken as requirement). So apart from Genarate method user can define any method and can call this in generate method, because this approach is not working so i have to write whole code into generate method only and code is also repetitive. Any help is really appreciable...

• Arithmetic operator confusion

  - by Dusk

  Why I'm getting two different values while using the arithmetic operators for the same value of variables. I've just altered little bit my second program, which is resulted in giving me the different output. Could anyone please tell me why? int number=113; int rot=0; rot=number%10; rot*=100+number/10; System.out.println(rot);//333 int number=113; int rot=0; rot=number%10; rot=rot*100+number/10; System.out.println(rot);//311

• Why can't my main class see the array in my calender class

  - by Rocky Celltick Eadie

  This is a homework problem. I'm already 5 days late and can't figure out what I'm doing wrong.. this is my 1st semester in Java and my first post on this site Here is the assignment.. Create a class called Calendar. The class should contain a variable called events that is a String array. The array should be created to hold 5 elements. Use a constant value to specify the array size. Do not hard code the array size. Initialize the array in the class constructor so that each element contains the string “ – No event planned – “. The class should contain a method called CreateEvent. This method should accept a String argument that contains a one-word user event and an integer argument that represents the day of the week. Monday should be represented by the number 1 and Friday should be represented by the number 5. Populate the events array with the event info passed into the method. Although the user will input one-word events, each event string should prepend the following string to each event: event_dayAppoinment: (where event_day is the day of the week) For example, if the user enters 1 and “doctor” , the first array element should read: Monday Appointment: doctor If the user enters 2 and “PTA” , the second array element should read: Tuesday Appointment: PTA Write a driver program (in a separate class) that creates and calls your Calendar class. Then use a loop to gather user input. Ask for the day (as an integer) and then ask for the event (as a one word string). Pass the integer and string to the Calendar object’s CreateEvent method. The user should be able enter 0 – 5 events. If the user enters -1, the loop should exit and your application should print out all the events in a tabular format. Your program should not allow the user to enter invalid values for the day of the week. Any input other than 1 – 5 or -1 for the day of the week would be considered invalid. Notes: When obtaining an integer from the user, you will need to use the nextInt() method on your Scanner object. When obtaining a string from a user, you will need to use the next() method on your Scanner object. Here is my code so far.. //DRIVER CLASS /** * * @author Rocky */ //imports scanner import java.util.Scanner; //begin class driver public class driver { /** * @paramargs the command line arguments */ //begin main method public static void main(String[] args) { //initiates scanner Scanner userInput = new Scanner (System.in); //declare variables int dayOfWeek; String userEvent; //creates object for calender class calendercalenderObject = new calender(); //user prompt System.out.println("Enter day of week for your event in the following format:"); System.out.println("Enter 1 for Monday"); System.out.println("Enter 2 for Tuesday"); System.out.println("Enter 3 for Wednsday"); System.out.println("Enter 4 for Thursday"); System.out.println("Enter 5 for Friday"); System.out.println("Enter -1 to quit"); //collect user input dayOfWeek = userInput.nextInt(); //user prompt System.out.println("Please type in the name of your event"); //collect user input userEvent = userInput.next(); //begin while loop while (dayOfWeek != -1) { //test for valid day of week if ((dayOfWeek>=1) && (dayOfWeek<=5)){ //calls createEvent method in calender class and passes 2 variables calenderObject.createEvent(userEvent,dayOfWeek); } else { //error message System.out.println("You have entered an invalid number"); //user prompts System.out.println("Press -1 to quit or enter another day"); System.out.println("Enter 1 for Monday"); System.out.println("Enter 2 for Tuesday"); System.out.println("Enter 3 for Wednsday"); System.out.println("Enter 4 for Thursday"); System.out.println("Enter 5 for Friday"); System.out.println("Enter -1 to quit"); //collect user input dayOfWeek = userInput.nextInt(); //end data validity test } //end while loop } //prints array to screen int i=0; for (i=0;i<events.length;i++){ System.out.println(events[i]); } //end main method } } /** * * @author Rocky */ //imports scanner import java.util.Scanner; //begin calender class public class calender { //creates events array String[] events = new String[5]; //begin calender class constructor public calender() { //Initializes array String[] events = {"-No event planned-","-No event planned-","-No event planned-","-No event planned-","-No event planned-"}; //end calender class constructor } //begin createEvent method public String[] createEvent (String userEvent, int dayOfWeek){ //Start switch test switch (dayOfWeek){ case 1: events[0] = ("Monday Appoinment:") + userEvent; break; case 2: events[1] = ("Tuesday Appoinment:") + userEvent; break; case 3: events[2] = ("WednsdayAppoinment:") + userEvent; break; case 4: events[3] = ("Thursday Appoinment:") + userEvent; break; case 5: events[4] = ("Friday Appoinment:") + userEvent; break; default: break; //End switch test } //returns events array return events; //end create event method } //end calender class }

• GetDiskFreeSpaceEx reports wrong number of free bytes

  - by rboorgapally

  __int64 i64FreeBytes unsigned __int64 lpFreeBytesAvailableToCaller, lpTotalNumberOfBytes, lpTotalNumberOfFreeBytes; // variables used to obtain // the free space on the drive GetDiskFreeSpaceEx (Manager.capDir, (PULARGE_INTEGER)&lpFreeBytesAvailableToCaller, (PULARGE_INTEGER)&lpTotalNumberOfBytes, (PULARGE_INTEGER)&lpTotalNumberOfFreeBytes); i64FreeBytes = lpTotalNumberOfFreeBytes; _tprintf(_T ("Number of bytes free on the drive:%I64u \n"), lpTotalNumberOfFreeBytes); I am working on a data management routine which is a Windows CE command line application. The above code shows how I get the number of free bytes on a particular drive which contains the folder Manager.capdir (it is the variable containing the full path name of the directory). My question is, the number of free bytes reported by the above code (the _tprintf statement) doesn't match with the number of free bytes of the drive (which i check by doing a right click on the drive). I wish to know if the reason for this difference?

• Effects of the `extern` keyword on C functions

  - by Elazar Leibovich

  In C I did not notice any effect of the extern keyword used before function declaration. At first I thougth that when defining extern int f(); in a single file forces you to implement it outside of the files scope, however I found out that both extern int f(); int f() {return 0;} And extern int f() {return 0;} Compiles just fine, with no warnings from gcc. I used gcc -Wall -ansi, he wouldn't even accept // comments. Are there any effects for using extern before function definitions? Or is it just an optional keyword with no side effects for functions. In the latter case I don't understand why did the standard designers chose to litter the grammar with superfluous keywords. EDIT: to clarify, I know there's usage for extern in variables, but I'm only asking about extern in functions.

• Fully automated SQL Server Restore

  - by hasen j

  I'm not very fluent with SQL Server commands. I need a script to restore a database from a .bak file and move the logical_data and logical_log files to a specific path. I can do: restore filelistonly from disk='D:\backups\my_backup.bak' This will give me a result set with a column LogicalName, next I need to use the logical names from the result set in the restore command: restore database my_db_name from disk='d:\backups\my_backups.bak' with file=1, move 'logical_data_file' to 'd:\data\mydb.mdf', move 'logical_log_file' to 'd:\data\mylog.ldf' How do I capture the logical names from the first result set into variables that can be supplied to the "move" command? I think the solution might be trivial, but I'm pretty new to SQL Server.

• How to Install two library CGNS for Fortran under WIndows XP

  - by user317368

  Hello, I have to install two libraries CGNS to use it in Fortan, but I don't understand how, the basic instructions are: To compile under MS Windows: configure.bat [options] then gmake if using GNU make, or nmake if using nmake. NOTE: This assumes that the cl compiler is in your path, and that the INCLUDE and LIB environment variables are set to include the directories containing the MSC include files and libraries. If not, you will need to use full path names to cl and link, and define INCLUDE and LIB in make.win32. You may also execute VCVARS32.BAT in the BIN directory of your VC installation to set these up prior to running nmake. so what i did was to: tape configure.bat it creates the rights files I set the news paths and lib, include for the cl.exe and link.exe but now the warning and error messages are about the clui.dll. cl -nologo -I. -Iadf -FoWIN32\cgns_error.obj -c cgns_error.c Cannot load language resource clui.dll what can i do now? I'm a beginner user in this field. Thankx Manal

• C: Expanding an array with malloc

  - by Mal Ock

  I'm a bit new to malloc and C in general. I wanted to know how I can, if needed, extend the size of an otherwise fixed-size array with malloc. Example: #define SIZE 1000 struct mystruct { int a; int b; char c; }; mystruct myarray[ SIZE ]; int myarrayMaxSize = SIZE; .... if ( i > myarrayMaxSize ) { // malloc another SIZE (1000) elements myarrayMaxSize += SIZE; } The above example should make clear what I want to accomplish. (By the way: I need this for an interpreter I write: Work with a fixed amount of variables and in case more are needed, just allocate them dynamically)

• ASP.NET 1.0 site error after upgrade to VS.NET 2010

  - by Keith

  Help. I installed VS.NET 2010 and now my existing ASP.NET MVC application won't run. I checked that the 1.0 version of System.Web.Mvc is still referenced but when I browse my application, I get an error like this: "Compiler Error Message: CS1579: foreach statement cannot operate on variables of type 'object' because 'object' does not contain a public definition for 'GetEnumerator'". My partial view has this declaration: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<ProductModel" %> //various import statements <div <% foreach (var category in Model.Categories) { % <span<%= category.Name %</span <span<%= category.Market%</span <% } % </div For what it's worth, the source view shows ViewUserControl in red and gives a tool tip reading "Cannot resolve symbol 'ViewUserControl'". My working code didn't change, the only delta is that I upgraded to VS.NET 2010 (which includes MVC 2.0); I'm sure something is not referenced correctly but I cannot figure out what's going on.

• Lamp with mod_fastcgi

  - by Jonathan

  Hi! I am building a cgi application, and now I would like it to be like an application that stands and parses each connection, with this, I can have all session variables saved in memory instead of saving them to file(or anyother place) and loading them again on a new connection I am using lamp within a linux vmware but I can't seem to find how to install the module for it to work and what to change in the httpd.conf. I tried to compile the module, but I couldn't because my apache isn't a regular instalation, its a lamp already built one, and it seems that the mod needs the apache directory to be compiled. I saw some coding examples out there, so I guess is not that hard once its runing ok with Apache Can you help me with this please? Thanks, Joe

• How can I use a variable as a module name in Perl?

  - by mjn12

  I know it is possible to use a variable as a variable name for package variables in Perl. I would like to use the contents of a variable as a module name. For instance: package Foo; our @names =("blah1", "blah2"); 1; And in another file I want to be able be able to set the contents of a scalar to "foo" and then access the names array in Foo through that scalar. my $packageName = "Foo"; Essentially I want to do something along the lines of: @{$packageName}::names; #This obviously doesn't work. I know I can use my $names = eval '$'. $packageName . "::names" But only if Foo::names is a scalar. Is there another way to do this without the eval statement?

• IOS where to put the configuration of facebook sdk

  - by Carol Smith

  I am trying to integrated my IOS 7 application with Facebook SDK I following this official tutorial https://developers.facebook.com/docs/ios/getting-started which states Configure the .plist Follow these three steps: Create a key called FacebookAppID with a string value, and add the app ID there. Create a key called FacebookDisplayName with a string value, and add the Display Name you configured in the App Dashboard. Create an array key called URL types with a single array sub-item called URL Schemes. Give this a single item with your app ID prefixed with fb. This is used to ensure the application will receive the callback URL of the web-based OAuth flow. The finished .plist should look something like this: My question is where to put these values? They already put this image, maybe it helps you to answer me Edit The problem that I don't have any plist file in my framework in xcode and I can't add a new one because if i did, I would have to add all the variables that you see in the image but the tutorial just stated about some of them

• How to compile a program which needs a newer version of glib

  - by michael

  Hi, I am trying to compile Webkit on Ubuntu 8.04. But when i run autogen.sh, I get the following error saying it needs a newer version of glib. So what is the safest way to install glib without screwing up the rest of my OS (since the rest needs 2.16 while webkit compile needs 2.21)? checking for GLIB... configure: error: Package requirements (glib-2.0 >= 2.21.3 gobject-2.0 >= 2.0 gthread-2.0 >= 2.0) were not met: Requested 'glib-2.0 >= 2.21.3' but version of GLib is 2.16.6 Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GLIB_CFLAGS and GLIB_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.

• Problem running gems in OS X

  I'm running Snow Leopard, and installed a custom built Ruby according to the guide here: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard . My ruby binary lives in usr/local/bin/ruby and my gems are installed in /usr/local/bin/gem . My gem env looks like so: RUBY VERSION: 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0] - INSTALLATION DIRECTORY: /Library/Ruby/Gems/1.8 - RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby - EXECUTABLE DIRECTORY: /usr/bin I think I may have borked the install since all actions taked on gems give the error: ERROR: While executing gem ...

• Searching Database by Arbitrary Date in PHP

  - by jverdi

  Suppose you have a messaging system built in PHP with a MySQL database backend, and you would like to support searching for messages using arbitrary date strings. The database includes a messages table, with a 'date_created' field represented as a datetime. Examples of the arbitrary date strings that would be accepted by the user should mirror those accepted by strtotime. For the following examples, searches performed on March 21, 2010: "January 26, 2009" would return all messages between 2009-01-26 00:00:00 and 2009-01-27 00:00:00 "March 8" would return all messages between 2010-03-08 00:00:00 and 2010-01-26 00:00:00 "Last week" would return all messages between 2010-03-14 00:00:00 and 2010-03-21 018:25:00 "2008" would return all messages between 2008-01-01 00:00:00 and 2008-12-31 00:00:00 I began working with date_parse, but the number of variables grew quickly. I wonder if I am re-inventing the wheel. Does anyone have a suggestion that would work either as a general solution or one that would capture most of the possible input strings?

• Using the "naked" attribute for functions in GCC

  - by Art Spasky

  GCC documentation (http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html) states in 6.29 Declaring Attributes of Functions "naked Use this attribute on the ARM, AVR, IP2K, RX and SPU ports to indicate that the specified function does not need prologue/epilogue sequences generated by the compiler. It is up to the programmer to provide these sequences. The only statements that can be safely included in naked functions are asm statements that do not have operands. All other statements, including declarations of local variables, if statements, and so forth, should be avoided. Naked functions should be used to implement the body of an assembly function, while allowing the compiler to construct the requisite function declaration for the assembler." Can I safely call functions using C syntax from naked functions, or only by using asm?

• optional search parameters in sql query and rows with null values

  - by glenn.danthi

  Ok here is my problem : Before i start the description, let me to tell you that I have googled up a lot and I am posting this question for a good optimal solution :) i am building a rest service on WCF to get userProfiles... the user can filter userProfiles by giving something like userProfiles?location=London now i have the following method GetUserProfiles(string firstname, string lastname, string age, string location) the sql query string i built is: select firstname, lastname, .... from profiles where (firstName like '%{firstname}%') AND (lastName like '%{lastName}%') ....and so on with all variables being replaced by string formatter. Problem with this is that it filters any row having firstname, lastname, age or location having a null value.... doing something like (firstName like '%{firstName}%' OR firstName IS NULL) would be tedious and the statement would become unmaintanable! (in this example there are only 4 arguments, but in my actual method there are 10) What would be the best solution for this?....How is this situation usually handled? Database used : MySql

• Why will this code compile using ifort compiler and not when using gfortran compiler? Help!

  I'm rewriting some code to make a program compile with the gfortran compiler as opposed to ifort compiler I usually use. The code follows: _Subroutine SlideBits (WORD, BITS, ADDR) Implicit None Integer(4) WORD Integer(4) BITS Integer(4) ADDR Integer(4) ADDR1 ADDR1 = 32 - ADDR WORD = (WORD .And. (.Not.ISHFT(1,ADDR1))) .Or. ISHFT(BITS,ADDR1) End_ When I compile the above code using the gfortran compiler, I recieve this error: WORD = (WORD .And. (.Not.ISHFT(1,ADDR1))) .Or. ISHFT(BITS,ADDR1) Error: Operand of .NOT. operator at (1) is INTEGER(4) All three of the variables coming into the subroutine are integers. I've looked around a bit and the gfortran wiki states that the gfortran compiler should be able to handle logical statments being applied to integer values. Several other sites I've visited either quote from the gnu wiki or agree with it. This is the first time I've seen this error as the Intel Fortran compiler (ifort) I normally use compiles cleanly.

• Port C's fread(&struct,....) to Python

  - by user287669

  Hey, I'm really struggling with this one. I'am trying to port a small piece of someone else's code to Python and this is what I have: typedef struct { uint8_t Y[LUMA_HEIGHT][LUMA_WIDTH]; uint8_t Cb[CHROMA_HEIGHT][CHROMA_WIDTH]; uint8_t Cr[CHROMA_HEIGHT][CHROMA_WIDTH]; } __attribute__((__packed__)) frame_t; frame_t frame; while (! feof(stdin)) { fread(&frame, 1, sizeof(frame), stdin); // DO SOME STUFF } Later I need to access the data like so: frame.Y[x][y] So I made a Class 'frame' in Python and inserted the corresponding variables(frame.Y, frame.Cb, frame.Cr). I have tried to sequentially map the data from Y[0][0] to Cr[MAX][MAX], even printed out the C struct in action but didn't manage to wrap my head around the method used to put the data in there. I've been struggling overnight with this and have to get back to the army tonight, so any immediate help is very welcome and appreciated. Thanks
