  • Not getting response using SOAP and PHP.

    - by Nitish
    I'm using PHP5 and NuSOAP - SOAP Toolkit for PHP. I created the server using the code below: <?php function getStockQuote($symbol) { mysql_connect('localhost','user','pass'); mysql_select_db('test'); $query = "SELECT stock_price FROM stockprices WHERE stock_symbol = '$symbol'"; $result = mysql_query($query); $row = mysql_fetch_assoc($result); echo $row['stock_price']; } $a=require('lib/nusoap.php'); $server = new soap_server(); $server->configureWSDL('stockserver', 'urn:stockquote'); $server->register("getStockQuote", array('symbol' => 'xsd:string'), array('return' => 'xsd:decimal'), 'urn:stockquote', 'urn:stockquote#getStockQuote'); $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server->service($HTTP_RAW_POST_DATA); ?> The client has the following code: <?php require_once('lib/nusoap.php'); $c = new soapclientNusoap('http://localhost/stockserver.php?wsdl'); $stockprice = $c->call('getStockQuote', array('symbol' => 'ABC')); echo "The stock price for 'ABC' is $stockprice."; ?> The database was created using the code below: CREATE TABLE `stockprices` ( `stock_id` INT UNSIGNED NOT NULL AUTO_INCREMENT , `stock_symbol` CHAR( 3 ) NOT NULL , `stock_price` DECIMAL(8,2) NOT NULL , PRIMARY KEY ( `stock_id` ) ); INSERT INTO `stockprices` VALUES (1, 'ABC', '75.00'); INSERT INTO `stockprices` VALUES (2, 'DEF', '45.00'); INSERT INTO `stockprices` VALUES (3, 'GHI', '12.00'); INSERT INTO `stockprices` VALUES (4, 'JKL', '34.00'); When I run the client the result I get is this: The stock price for 'ABC' is . 75.00 is not being printed as the price.

  • Why is this an invalid Turing machine?

    - by Danny King
    Whilst doing exam revision I am having trouble answering the following question from the book, "An Introduction to the Theory of Computation" by Sipser. Unfortunately there's no solution to this question in the book. Explain why the following is not a legitimate Turing machine. M = { The input is a polynomial p over variables x1, ..., xn Try all possible settings of x1, ..., xn to integer values Evaluate p on all of these settings If any of these settings evaluates to 0, accept; otherwise reject. } This is driving me crazy! I suspect it is because the set of integers is infinite? Does this somehow exceed the alphabet's allowable size? Thanks!

  • Extracting text from a file where date -time is the index

    - by Soham
    I have got around 800 files of maximum 55KB-100KB each where the data is in this format Date/Time/Float1/Float2/Float3/Float4/Integer Date is in DD/MM/YYYY format and Time is in the format of HH:MM Here the date ranges from say 1st May to 1June and each day, the Time varies from 09:00 to 15:30. I want to run a program so that, for each file, it extracts the data pertaining to a particular given date and writes to a file. I will not face any problem in writing into directory operations. I am trying to get around, to form a to do a search and extract operation. I dont know, how to do it, would like to have some idea. Thanks Soham

  • IEnumerable.Cast<>

    - by Renato Person
    If I can implicitly cast an integer value to a double (and vice versa), like: int a = 4; double b = a; // now b holds 4.0 Why can I not do this: int[] intNumbers = {10, 6, 1, 9}; double[] doubleNumbers2 = intNumbers.Cast<double>().ToArray<double>(); I get an "Specified cast is not valid" error message. Doing the opposite (casting from double to int) results in the same error. What am I doing wrong?

  • Round prices up to nearest 5 after conversion in oscommerce

    - by Rhyso
    Hi there, A conversion question relating to prices in oscommerce: I am needing for a custom currency conversion to round the USD prices up to the nearest 5$ to avoid prices being displayed at silly prices such as $263. I am trying to convert to an int and round the following line : $curr-display_price($listing['products_price'], tep_get_tax_rate($listing['products_tax_class_id'])); ( as for some reason the price is displayed as a string, im guessing to include the currency sign) However not having much luck. Does anybody know where the root conversion takes place as it might be easier for me to round() or ceil() from there when it is a raw integer Or any other ideas of how I can round the conversion? Thanks for any help Rhys Thomas

  • Implementing parts of rfc4226 (HOTP) in mysql

    - by Moose Morals
    Like the title says, I'm trying to implement the programmatic parts of RFC4226 "HOTP: An HMAC-Based One-Time Password Algorithm" in SQL. I think I've got a version that works (in that for a small test sample, it produces the same result as the Java version in the code), but it contains a nested pair of hex(unhex()) calls, which I feel can be done better. I am constrained by a) needing to do this algorithm, and b) needing to do it in mysql, otherwise I'm happy to look at other ways of doing this. What I've got so far: -- From the inside out... -- Concatinate the users secret, and the number of time its been used -- find the SHA1 hash of that string -- Turn a 40 byte hex encoding into a 20 byte binary string -- keep the first 4 bytes -- turn those back into a hex represnetation -- convert that into an integer -- Throw away the most-significant bit (solves signed/unsigned problems) -- Truncate to 6 digits -- store into otp -- from the otpsecrets table select (conv(hex(substr(unhex(sha1(concat(secret, uses))), 1, 4)), 16, 10) & 0x7fffffff) % 1000000 into otp from otpsecrets; Is there a better (more efficient) way of doing this?

  • mysql fulltext search as level2 index

    - by Nir
    lets say I have a table with product details. one of the fields is category (integer). I want to do fulltext search on product name in specific category. Unfortunately Mysql does not allow me to specify index that includes category and product name as fulltext. It looks like I can use fulltext only on product_name and theefore any fulltext search will search product names in all categories. Is there any way to solve this (allow fulltext search/index only on products in category)?

  • Enum in Hibernate, persisting as an enum

    - by niklassaers
    In my MySQL database, there's the column "gender enum('male','female')" I've created my enum "com.mydomain.myapp.enums.Gender", and in my Person entity I'm defined "Gender gender". Now I'd want to keep the enum type in my MySQL database, but when I launch my application I get: Wrong column type in MyApp.Person for column Gender. Found: enum, expected: integer Why is this? This would be the equivalent as if I'd annotated my "Gender gender" with "@Enumerated(EnumType.ORDINAL)", which I haven't. EnumType seems only to be able to be either ORDINAL or STRING, so how do I specify that it should treat the field as an enum, not as an int? (not that there's much difference, but enough for it to get upset about it.)

  • Automating Visual Studio 2010 from a console app

    - by JoelFan
    I am trying to run the following code (which I got from here). The code just creates a new "Output" pane in Visual Studio and writes a few lines to it. Public Sub WriteToMyNewPane() Dim win As Window = _ DTE.Windows.Item(EnvDTE.Constants.vsWindowKindOutput) Dim ow As OutputWindow = win.Object Dim owPane As OutputWindowPane Dim cnt As Integer = ow.OutputWindowPanes.Count owPane = ow.OutputWindowPanes.Add("My New Output Pane") owPane.Activate() owPane.OutputString("My text1" & vbCrLf) owPane.OutputString("My text2" & vbCrLf) owPane.OutputString("My text3" & vbCrLf) End Sub Instead of running it as a Macro, I want to run it as an independent console application that connects to a currently running instance of Visual Studio 2010. I'm having a hard time figuring out how to set the value of DTE. I think I may need to call GetActiveObject, but I'm not sure how. Any pointers?

  • How to write to a varchar(max) column using ODBC

    - by andyjohnson
    Summary: I'm trying to write a text string to a column of type varchar(max) using ODBC and SQL Server 2005. It fails if the length of the string is greater than 8000. Help! I have some C++ code that uses ODBC (SQL Native Client) to write a text string to a table. If I change the column from, say, varchar(100) to varchar(max) and try to write a string with length greater than 8000, the write fails with the following error [Microsoft][ODBC SQL Server Driver]String data, right truncation So, can anyone advise me on if this can be done, and how? Some example (not production) code that shows what I'm trying to do: SQLHENV hEnv = NULL; SQLRETURN iError = SQLAllocEnv(&hEnv); HDBC hDbc = NULL; SQLAllocConnect(hEnv, &hDbc); const char* pszConnStr = "Driver={SQL Server};Server=127.0.0.1;Database=MyTestDB"; UCHAR szConnectOut[SQL_MAX_MESSAGE_LENGTH]; SWORD iConnectOutLen = 0; iError = SQLDriverConnect(hDbc, NULL, (unsigned char*)pszConnStr, SQL_NTS, szConnectOut, (SQL_MAX_MESSAGE_LENGTH-1), &iConnectOutLen, SQL_DRIVER_COMPLETE); HSTMT hStmt = NULL; iError = SQLAllocStmt(hDbc, &hStmt); const char* pszSQL = "INSERT INTO MyTestTable (LongStr) VALUES (?)"; iError = SQLPrepare(hStmt, (SQLCHAR*)pszSQL, SQL_NTS); char* pszBigString = AllocBigString(8001); iError = SQLSetParam(hStmt, 1, SQL_C_CHAR, SQL_VARCHAR, 0, 0, (SQLPOINTER)pszBigString, NULL); iError = SQLExecute(hStmt); // Returns SQL_ERROR if pszBigString len > 8000 The table MyTestTable contains a single colum defined as varchar(max). The function AllocBigString (not shown) creates a string of arbitrary length. I understand that previous versions of SQL Server had an 8000 character limit to varchars, but not why is this happening in SQL 2005? Thanks, Andy

  • How to prevent "Local transaction already has 1 non-XA Resource" exception?

    - by Zeratul
    Hi, I'm using 2 PU in stateless EJB and each of them is invoked on one method: @PersistenceContext(unitName="PU") private EntityManager em; @PersistenceContext(unitName="PU2") private EntityManager em2; @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW ) public void getCandidates(final Integer eventId) throws ControllerException { ElectionEvent electionEvent = em.find(ElectionEvent.class, eventId); ... Person person = getPerson(candidate.getLogin()); ... } @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW ) private Person getPerson(String login) throws ControllerException { Person person = em2.find(Person.class, login); return person; } Those methods are annotated with REQUIRES_NEW transcaction to avoid this exception. When I was calling these method from javaFX applet, all worked as expected. Now I'm trying to call them from JAX-RS webservice (I don't see any logical difference as in both cases ejb was looked up in initial context) and I keep getting this exception. When I set up XADatasource in glassfish 2.1 connection pools, I got nullpointer exception on em2. Any ideas what to try next? Regards

  • How to determine the data type of a CvMat

    - by Chris
    When using the CvMat type, the type of data is crucial to keeping your program running. For example, depending on whether your data is type float or unsigned char, you would choose one of these two commands: cvmGet(mat, row, col); cvGetReal2D(mat, row, col); Is there a universal approach to this? If the wrong data type matrix is passed to these calls, they crash at runtime. This is becoming an issue, since a function I have defined is getting passed several different types of matrices. How do you determine the data type of a matrix so you can always access its data? I tried using the "type()" function as such. CvMat* tmp_ptr = cvCreateMat(t_height,t_width,CV_8U); std::cout << "type = " << tmp_ptr->type() << std::endl; This does not compile, saying "term does not evaluate to a function taking 0 arguments". If I remove the brackets after the word type, I get a type of 1111638032 EDIT minimal application that reproduces this... int main( int argc, char** argv ) { CvMat *tmp2 = cvCreateMat(10,10, CV_32FC1); std::cout << "tmp2 type = " << tmp2->type << " and CV_32FC1 = " << CV_32FC1 << " and " << (tmp2->type == CV_32FC1) << std::endl; } Output: tmp2 type = 1111638021 and CV_32FC1 = 5 and 0

  • Why is it assumed that send may return with less than requested data transmitted on a blocking socke

    - by Ernelli
    The standard method to send data on a stream socket has always been to call send with a chunk of data to write, check the return value to see if all data was sent and then keep calling send again until the whole message has been accepted. For example this is a simple example of a common scheme: int send_all(int sock, unsigned char *buffer, int len) { int nsent; while(len 0) { nsent = send(sock, buffer, len, 0); if(nsent == -1) // error return -1; buffer += nsent; len -= nsent; } return 0; // ok, all data sent } Even the BSD manpage mentions that ...If no messages space is available at the socket to hold the message to be transmitted, then send() normally blocks... Which indicates that we should assume that send may return without sending all data. Now I find this rather broken but even W. Richard Stevens assumes this in his standard reference book about network programming, not in the beginning chapters, but the more advanced examples uses his own writen (write all data) function instead of calling write. Now I consider this still to be more or less broken, since if send is not able to transmit all data or accept the data in the underlying buffer and the socket is blocking, then send should block and return when the whole send request has been accepted. I mean, in the code example above, what will happen if send returns with less data sent is that it will be called right again with a new request. What has changed since last call? At max a few hundred CPU cycles have passed so the buffer is still full. If send now accepts the data why could'nt it accept it before? Otherwise we will end upp with an inefficient loop where we are trying to send data on a socket that cannot accept data and keep trying, or else? So it seems like the workaround, if needed, results in heavily inefficient code and in those circumstances blocking sockets should be avoided at all an non blocking sockets together with select should be used instead.

  • Querying a Single Column with LINQ

    - by Hossein Margani
    Hi Every one! I want to fetch array of values of a single column in a table, for example, I have a table named Customer(ID,Name), and want to fetch ids of all customers. my query in LINQ is: var ids = db.Customers.Select(c=>c.ID).ToList(); The answer of this query is correct, but I ran SQL Server Profiler, and saw the query which was like this: SELECT [t0].[ID], [t0].[Name] FROM [dbo].[Customer] AS [t0] I understood that LINQ selects all columns and then creates the integer array of ID fields. How can I write a LINQ query which generates this query in SQL Server: SELECT [t0].[ID] FROM [dbo].[Customer] AS [t0] Thank you.

  • How is joystick axis information formatted from a USB Joystick?

    - by aquanar
    I actually just have a rather small question, but I have had the HARDEST time finding information about it. For the application I am programming for, there will be a 3-axis joystick being connected via USB to a Windows XP computer, and it is being handled by directx. That information will then be sent elsewhere to an embedded controller. I don't need to know too much of the intricacies of how directx handles it, but I want to know, how is the data for the axes formatted? Nearest I can tell, most joysticks nowadays have 12 bits of resolution, so is the data output as a 12-bit 2's compliment number? And after that, is it represented as a signed 16-bit integer when it is captured from directx? I'd like to know this so I know how I will work with the data at the embedded platform side, such as how to format the packets sending data to the embedded side, as well ashow to use the information once it is on the embedded side.

  • How to make Databinding type safe and support refactoring

    - by Ian Ringrose
    When I wish to bind a control to a property of my object, I have to provide the name of the property as a string. This is not very good because: If the property is removed or renamed, I don’t get a compiler warning. If a rename the property with a refactoring tool, it is likely the data binding will not be updated. I don’t get an error until runtime if the type of the property is wrong, e.g. binding an integer to a date chooser. Is there a design-paten that gets round this, but still has the ease of use of data-binding? (This is a problem in WinForm, Asp.net and WPF and most likely lots of other systems) I have now found "workarounds for nameof() operator in C#: typesafe databinding" that also has a good starting point for a solution.

  • Hibernate Subquery and DetachedCriteria

Tried to use .add.Subqueries.geAll(.... But cannot make it work properly. I could not find proper documentation on the Subqueries in Hibernate. Tips are welcomed.

  • Unable to reverse seemingly simple rails migration - getting "altered_table.column may not be NULL"

    - by brad
    I have a table 'invoices' in my development database (sqlite3) populated with a small amount of test data. I wanted to add a column 'invoice_number' to it and set up a migration like so: class AddInvoiceNumberColumnToInvoices < ActiveRecord::Migration def self.up add_column :invoices, :invoice_number, :integer end def self.down remove_column :invoices, :invoice_number end end I ran rake db:migrate and it seemed to migrate just fine. However, when I tried to access this column through ActiveRecord it didn't seem to be there. I decided to undo this migration and try again (not sure what I was going to try but I thought I'd start by undoing it) with rake db:migrate VERSION='whatever_the_migration_before_this_one_was_called'. This failed with the error message == AddInvoiceNumberColumnToInvoices: reverting =============================== -- remove_column(:invoices, :invoice_number) rake aborted! An error has occurred, this and all later migrations canceled: altered_invoices.invoice_number may not be NULL I can't find any documentation of this error. Is anyone able to explain what I have done wrong, and more importantly how I can fix this?
