  • mysqli insert problem

    - by Simon
    Hello i have this error: Warning: mysqli_stmt::bind_param() [mysqli-stmt.bind-param]: Number of elements in type definition string doesn't match number of bind variables in E:\wamp\www\classes\UserLogin.php on line 31 and i dont know what it is :/ here is my code function createUser($username, $password) { $mysql = connect(); if($stmt = $mysql->prepare('INSERT INTO users (username, password, alder, hood, fornavn, efternavn, city, ip, level, email) VALUES (?,?,?,?,?,?,?,?,?,?)')) { $stmt->bind_param($username,$password, $alder, $hood, $fornavn, $efternavn, $city, $ip, $level, $email); $stmt->execute(); $stmt->close(); } else { echo 'error: ' . $mysql->error; } then my user create the user they only need to type username and password, and later they can edit the profile and edit, email,alder,hood and like that :).

  • SIGSEGV problem

    - by sickmate
    I'm designing a protocol (in C) to implement the layered OSI network structure, using cnet (http://www.csse.uwa.edu.au/cnet/). I'm getting a SIGSEGV error at runtime, however cnet compiles my source code files itself (I can't compile it through gcc) so I can't easily use any debugging tools such as gdb to find the error. Here's the structures used, and the code in question: typedef struct { char *data; } DATA; typedef struct { CnetAddr src_addr; CnetAddr dest_addr; PACKET_TYPE type; DATA data; } Packet; typedef struct { int length; int checksum; Packet datagram; } Frame; static void keyboard(CnetEvent ev, CnetTimerID timer, CnetData data) { char line[80]; int length; length = sizeof(line); CHECK(CNET_read_keyboard((void *)line, (unsigned int *)&length)); // Reads input from keyboard if(length > 1) { /* not just a blank line */ printf("\tsending %d bytes - \"%s\"\n", length, line); application_downto_transport(1, line, &length); } } void application_downto_transport(int link, char *msg, int *length) { transport_downto_network(link, msg, length); } void transport_downto_network(int link, char *msg, int *length) { Packet *p; DATA *d; p = (Packet *)malloc(sizeof(Packet)); d = (DATA *)malloc(sizeof(DATA)); d->data = msg; p->data = *d; network_downto_datalink(link, (void *)p, length); } void network_downto_datalink(int link, Packet *p, int *length) { Frame *f; // Encapsulate datagram and checksum into a Frame. f = (Frame *)malloc(sizeof(Frame)); f->checksum = CNET_crc32((unsigned char *)(p->data).data, *length); // Generate 32-bit CRC for the data. f->datagram = *p; f->length = sizeof(f); //Pass Frame to the CNET physical layer to send Frame to the require link. CHECK(CNET_write_physical(link, (void *)f, (size_t *)f->length)); free(p->data); free(p); free(f); } I managed to find that the line: CHECK(CNET_write_physical(link, (void *)f, (size_t *)f-length)); is causing the segfault but I can't work out why. Any help is greatly appreciated.

  • Problem when reading input in C

    - by gcx
    I've made a Linked List. Its elements keep both previous and next items' address. It gets commands from an input file. It detects the command and uses the following statement as a parameter. (text: add_to_front john - means: add_to_front(john)) Code: http://pastebin.com/KcAm1y3L When I try to give the commands from an input file it gives me same output over and over. However, if I write inputs in main() manually, it works. For ex input file: add_to_front john add_to_back jane add_to_back jane print (unfortunately) the output is: >add_to_front john >add_to_back jane >add_to_back jane >print jane jane jane Although, if I write add_to_front(john); add_to_back(jane); add_to_back(jane); print(); instead of this command check: while (scanf("%s",command)!=EOF) { if (strcmp(command,"add_to_front")==0) { gets(parameter); add_to_front(parameter); } else if (strcmp(command,"add_to_back")==0) { gets(parameter); add_to_back(parameter); } else if (strcmp(command,"remove_from_back")==0) remove_from_back(parameter); ... printf(" HUH?\n"); } } in main() it gives the correct output. I know it's a lot to ask but this thing is bothering me for 2 days. What do you think i'm doing wrong?

  • Problem with writing a hexadecimal string

    - by quilby
    Here is my code /* gcc -c -Wall -g main.c gcc -g -lm -o main main.o */ #include <stdlib.h> #include <stdio.h> #include <string.h> void stringToHex(const char* string, char* hex) { int i = 0; for(i = 0; i < strlen(string)/2; i++) { printf("s%x", string[2*i]); //for debugging sprintf(&hex[i], "%x", string[2*i]); printf("h%x\n", hex[i]); //for debugging } } void writeHex(char* hex, int length, FILE* file, long position) { fseek(file, position, SEEK_SET); fwrite(hex, sizeof(char), length, file); } int main(int argc, char** argv) { FILE* pic = fopen("hi.bmp", "w+b"); const char* string = "f2"; char hex[strlen(string)/2]; stringToHex(string, hex); writeHex(hex, strlen(string)/2, pic, 0); fclose(pic); return 0; } I want it to save the hexadecimal number 0xf2 to a file (later I will have to write bigger/longer numbers though). The program prints out - s66h36 And when I use hexedit to view the file I see the number '36' in it. Why is my code not working? Thanks!

  • Using Rails, problem testing has_many relationship

    - by east
    The summary is that I've code that works when manually testing, but isn't doing what I would think it should when trying to build an automated test. Here are the details: I've two models: Payment and PaymentTranscation. class Payment ... has_many :transactions, :class_name => 'PaymentTransaction' class PaymentTranscation ... belongs_to payment The PaymentTransaction is only created in a Payment model method, like so: def pay_up ... transactions.create!(params...) ... end I've manually tested this code, inspected the database, and everything works well. The failing automated test looks like this: def test_pay_up purchase = Payment.new(...) assert purchase.save assert_equal purchase.state, :initialized.to_s assert purchase.pay_up # this should create a new PaymentTransaction... assert_equal purchase.state, :succeeded.to_s assert_equal purchase.transactions.count, 1 # FAILS HERE; transactions is an empty array end If I step through the code, it's clear that the PaymentTransaction is getting created correctly (though I can't see it in the database because everything is in a testing transaction). What I can't figure out is why transactions is returning an empty array in the test when I know a valid PaymentTransaction is getting created. Anybody have some suggestions? Thanks in advance, east

  • Problem with filling dataset

    - by Brian
    This is a small portion of my code file. Each time my debugger reaches the line 'NewDA.Fill(NewDS);' at runtime it jumps to the catch. I'm positive the daynumber variable gets a value that's present in the database and I've tried the query outside of the codefile on my database and it works fine. I'm also using the connectionstring 'db' on more parts of the code with successful results. string QueryNew = "SELECT activityname AS [Name], activitycategorynumber AS [Category] " + "FROM ACTIVITY WHERE daynumber = @daynumber"; SqlCommand NewCmd = new SqlCommand(QueryNew, db); NewCmd.Parameters.Add("@daynumber", SqlDbType.Int).Value = daynumber; SqlDataAdapter NewDA = new SqlDataAdapter(NewCmd); DataSet NewDS = new DataSet(); NewDA.Fill(NewDS);

  • EF problem with entity re-ordering and uniqueness constraint

    - by wpfwannabe
    I am using Entity Framework and I've come to an interesting stumbling block. Let's say there is a db table "Item" with "sequence" column of type int (and others of course). Column "sequence" must be unique and it is used for (re)ordering of items. EF maps this table to "Item" class with "sequence" int property. Now let's say I want to swap position of two items by mutually exchanging each other's sequence number. Upon calling SaveChanges() EF throws an exception complaining about "sequence" uniqueness. It probably generates two UPDATEs and the first one probably fails. I assume that plain SQL solution to this issue is using a third UPDATE to introduce a unique sequence value in the process but I am stuck with EF. Any thoughts?

    Hi, I am able to display any data (numbers) in Flex AdvancedDataGrid except data with lot of digits after decimal places (0.000000000029103830456733704) or exponential numbers (293E-17). Grid is displaying -17 instead of 293E-17. Is it happening because of any limit to displaying data range in grid? If yes, what is the limit? Thanks in advance ... Atul

  • Rails Google Maps integration Javascript problem

    - by JZ
    I'm working on Rails 3.0.0.beta2, following Advanced Rails Recipes "Recipe #32, Mark locations on a Google Map" and I hit a road block: I do not see a google map. My @adds view uses @adds.to_json to connect the google maps api with my model. My database contains "latitude" "longitude", as floating points. And the entire project can be accessed at github. Can you see where I'm not connecting the to_json output with the javascript correctly? Can you see other glairing errors in my javascript? Thanks in advance! My application.js file: function initialize() { if (GBrowserIsCompatible() && typeof adds != 'undefined') { var map = new GMap2(document.getElementById("map")); map.setCenter(new GLatLng(37.4419, -122.1419), 13); map.addControl(new GLargeMapControl()); function createMarker(latlng, add) { var marker = new GMarker(latlng); var html="<strong>"+add.first_name+"</strong><br />"+add.address; GEvent.addListener(marker,"click", function() { map.openInfoWindowHtml(latlng, html); }); return marker; } var bounds = new GLatLngBounds; for (var i = 0; i < adds.length; i++) { var latlng=new GLatLng(adds[i].latitude,adds[i].longitude) bounds.extend(latlng); map.addOverlay(createMarker(latlng, adds[i])); } map.setCenter(bounds.getCenter(),map.getBoundsZoomLevel(bounds)); } } window.onload=initialize; window.onunload=GUnload; Layouts/adds.html.erb: <script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=true_or_false&amp;key=ABQIAAAAeH4ThRuftWNHlwYdvcK1QBTJQa0g3IQ9GZqIMmInSLzwtGDKaBQvZChl_y5OHf0juslJRNx7TbxK3Q" type="text/javascript"></script> <% if @adds -%> <script type="text/javascript"> var maps = <%= @adds.to_json %>; </script> <% end -%>

  • GWT Date Picker Format problem when saving a java date through hibernate in postgresql

    - by Noor
    Hi, I am using Java Date and Hibernate which is then being saved in the database (Postgresql). I am not that good in hibernate Part of the Mapping File <property name="DateOfBirth" type="java.util.Date"> <column name="DATEOFBIRTH" /> </property> I am using GWT Date picker Short date format i.e. yyyy-MM-dd. I am getting the value from the date picker using View.getUserDateOfBirth().getValue() But when I am saving the date 2010-11-30 into the datebase it is saving it as 2010-11-30 00:00:00 instead of 2010-11-30 So, I want it to be saved in the database as in this format 2010-11-30?? I have many things such timestamp but i not being able to configure it.

  • NHibernate stored procedure problem

    - by Calvin
    I'm having a hard time trying to get my stored procedure works with NHibernate. The data returned from the SP does not correspond to any database table. This is my mapping file: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="DomainModel" namespace="DomainModel.Entities"> <sql-query name="DoSomething"> <return class="SomeClass"> <return-property name="ID" column="ID"/> </return> exec [dbo].[sp_doSomething] </sql-query> </hibernate-mapping> Here is my domain class: namespace DomainModel.Entities { public class SomeClass { public SomeClass() { } public virtual Guid ID { get; set; } } } When I run the code, it fails with Exception Details: NHibernate.HibernateException: Errors in named queries: {DoSomething} at line 80 Line 78: config.Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "NHibernate.config")); Line 79: Line 80: g_sessionFactory = config.BuildSessionFactory(); When I debug into NHibernate code, it seems that SomeClass is not added to the persister dictionary because there isn't a class mapping (only sql-query) defined in hbm.xml. And later on in CheckNamedQueries function, it is not able to find the persistor for SomeClass. I've checked all the obvious things (e.g. make hbm as an embedded resource) and my code isn't too much different from other samples I found on the web, but somehow I just can't get it working. Any idea how I can resolve this issue?

  • Include Problem with Objective-C++ and OpenGL

    - by Stephen Furlani
    Hello, I feel silly asking this but I've searched for 'include problems' and have only come up with basic stuff. I'm working with an API that includes/imports in their header files (ARGH! HATE ANGER DESTRUCTION). One of these Obj-C files #import "OpenGL/CGLMacros.h" which #define's things like glMatrixMode(...); In my code I need the glMatrixMode(...); from #include "OpenGL/gl.h" but it won't access it! I can't edit the headers from the (poorly) coded API to put the includes in their definition files. What can I do? If the CGLMacros.h file starts out like /* Copyright: (c) 1999 by Apple Computer, Inc., all rights reserved. */ #ifndef _CGLMACRO_H #define _CGLMACRO_H Can I put a #define _CGLMACRO_H before I include the offending API header file? -Stephen
