  • Insert multiple records from a XML string differing on one parameter in SQL SERVER 2008

    - by Rohit
    Below in a query which inserts records to SimpleDictationProfileMapping table after reading it from a XML string. Now this query inserts a single record in which DictationCaptureProfileID is @dictationCaptureProfileId . Now i want to insert multiple rows in which @dictationCaptureProfileId is different and other 2 values are same. What i want to achieve by this is in case parent changes all child values should also change. INSERT INTO SimpleDictationProfileMapping ( DictationCaptureProfileID, DictationProfileMappingAttributeID, DictationProfileMappingAttributeValue ) SELECT @dictationCaptureProfileId, row.value('@attrId','varchar(max)'), row.value('@value', 'varchar(max)') FROM @simpleDictationCaptureProfileMappings.nodes('/simpleMappingAtribute/attribute') AS d ( row ) ; I want INSERT INTO SimpleDictationProfileMapping ( DictationCaptureProfileID OR (SELECT DictationCaptureProfileID FROM DictationCaptureProfile WHERE SystemDictationCaptureProfileID = @systemDictationCaptureProfileID), DictationProfileMappingAttributeID, DictationProfileMappingAttributeValue ) SELECT @dictationCaptureProfileId , row.value('@attrId','varchar(max)'), row.value('@value', 'varchar(max)') FROM @simpleDictationCaptureProfileMappings.nodes ('/simpleMappingAtribute/attribute') AS d ( row ) ; Please tell how to achieve this.

  • C# define string format of double/floats to be US english by default

    - by neil
    Hi, I have got several thousands of lines of a web application source code, initially written on a US development system, to maintain. It makes heavy use of SQL statement strings, which are combined on the fly, e.g. string SQL = "select * from table where double_value = " + Math.Round(double_value, 2); Don't comment on bad programming style, that doesn't help me in this case :) The cruix: My system uses a German locale, which in turn leads to wrong SQL statements, like this: "select * from table where double_value = 15,5" (Note the comma as decimal separator instead of a point). Question: What is the most "elegant" way to change the locale of the web app in this case) to US or UK in order to prevent being forced to change and inspect every single line of code? .net 3.5 is not an option (would give me the chance to overwrite ToString() in an extension class) Kind regards

  • How do we achieve "substring-match" under O(n) time?

    - by Pacerier
    I have an assignment that requires reading a huge file of random inputs, for example: Adana Izmir Adnan Menderes Apt Addis Ababa Aden ADIYAMAN ALDAN Amman Marka Intl Airport Adak Island Adelaide Airport ANURADHAPURA Kodiak Apt DALLAS/ADDISON Ardabil ANDREWS AFB etc.. If I specify a search term, the program is supposed to find the lines whereby a substring occurs. For example, if the search term is "uradha", the program is supposed to show ANURADHAPURA. If the search term is "airport", the program is supposed to show Amman Marka Intl Airport, Adelaide Airport A quote from the assignment specs: "You are to program this application taking efficiency into account as though large amounts of data and processing is involved.." I could easily achieve this functionality using a loop but the performance would be O(n). I was thinking of using a trie but it seems to only work if the substring starts from index 0. I was wondering what solutions are there which gives a performance better than O(n)?

    - by Deepak Konidena
    Hi, I run into the following errors when i try to store a large file into a string. Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2882) at java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:100) at java.lang.AbstractStringBuilder.append(AbstractStringBuilder.java:515) at java.lang.StringBuffer.append(StringBuffer.java:306) at rdr2str.ReaderToString.main(ReaderToString.java:52) As is evident, i am running out of heap space. Basically my pgm looks like something like this. FileReader fr = new FileReader(<filepath>); sb = new StringBuffer(); char[] b = new char[BLKSIZ]; while ((n = fr.read(b)) > 0) sb.append(b, 0, n); fileString = sb.toString(); Can someone suggest me why i am running into heap space error? Thanks.

    sTypeName = ... //do some string stuff here to get the name of the type /* The Assembly.CreateInstance function returns a type of System.object. I want to type cast it to the type whose name is sTypeName. assembly.CreateInstance(sTypeName) So, in effect I want to do something like: */ assembly.CreateInstance(sTypeName) as Type.GetType(sTypeName); How do I do that? And, what do I take on the left side of the assignment expression, assuming this is C# 2.0. I don't have the var keyword.

  • Implement python replace() function without using regexp

    - by jwesonga
    I'm trying to rewrite the equivalent of the python replace() function without using regexp. Using this code, i've managed to get it to work with single chars, but not with more than one character: def Replacer(self, find_char, replace_char): s = [] for char in self.base_string: if char == find_char: char = replace_char #print char s.append(char) s = ''.join(s) my_string.Replacer('a','E') Anybody have any pointers how to make this work with more than one character? example: my_string.Replacer('kl', 'lll')

  • Convert matched string of UTF-8 values to UTF-8 characters in Ruby

    - by user1475154
    Trying to convert output from a rest_client GET to the characters that are represented with escape sequences. Input: ..."sub_id":"\u0d9c\u8138\u8134\u3f30\u8139\u2b71"... (which I put in 'all_subs') Match: m = /sub_id\"\:\"([^\"]+)\"/.match(all_subs.to_str) [1] Print: puts m.force_encoding("UTF-8").unpack('U*').pack('U*') But it just comes out the same way I put it in. ie, "\u0d9c\u8138\u8134\u3f30\u8139\u2b71" However, if I convert a raw string of it: puts "\u0d9c\u8138\u8134\u3f30\u8139\u2b71".unpack('U*').pack('U*') The output is perfect as "??????"

  • How to prefix a positive number with plus sign in PHP

    - by user318466
    I need to design a function to return negative numbers unchanged but should add a + sign at the start of the number if its already no present. Example: Input Output ---------------- +1 +1 1 +1 -1 -1 It will get only numeric input. function formatNum($num) { # something here..perhaps a regex? } This function is going to be called several times in echo/print so the quicker the better.

  • What is the fastest way to trim blank lines from beginning and end of array?

    - by Edward Tanguay
    This script: <?php $lines[] = ''; $lines[] = 'first line '; $lines[] = 'second line '; $lines[] = ''; $lines[] = 'fourth line'; $lines[] = ''; $lines[] = ''; $lineCount = 1; foreach($lines as $line) { echo $lineCount . ': [' . trim($line) . ']<br/>'; $lineCount++; } ?> produces this output: 1: [] 2: [first line] 3: [second line] 4: [] 5: [fourth line] 6: [] 7: [] What is the fastest, most efficient way to change the above script so that it also deletes the preceding and trailing blank entries but not the interior blank entries so that it outputs this: 1: [first line] 2: [second line] 3: [] 4: [fourth line] I could use the foreach loop but I imagine there is a way with array_filter or something similar which is much more efficient.

  • Storing the HTML output from a local PHP file into a string using file_get_contents

    - by bobo
    There is a header.php file and it contains some php codes that return HTML. I know I can use require, include to echo the results, but what I want to do is to store its processed output string into a variable. In a page, I used: $headerHTML=file_get_contents('header.php'); Then I got the PHP code output rather than the processed HTML output. I know adding http:// would help. But I prefer to keep using relative path, how can I tell the function to treat the php file correctly?

  • error in mysql syntax in vb.net

  • update columns when value is numeric in tsql

    - by knittl
    i want to normalize date fields from an old badly designed db dump. i now need to update every row, where the datefield only contains the year. update table set date = '01.01.' + date where date like '____' and isnumeric(date) = 1 and date >= 1950 but this will not work, because sql does not do short circuit evaluation of boolean expressions. thus i get an error "error converting nvarchar '01.07.1989' to int" is there a way to work around this? the column also contains strings with a length of 4, which are not numbers (????, 5/96, 70/8, etc.) the table only has 60000 rows

Once it gets to the end of the $chars array (`~`) it should add on another charter. Run though those combinations ('! ', '" ', ... '~ ', ' !' ... '~~', ' ', ect). And then just keep on going ...

  • FF extension: displaying an array of string elements in a sidebar

    - by sujay-jain
    I am developing a ff extension which displays a list of elements from an array (dynamic) in the sidebar. The array is dynamic and needs to be constructed in a function everytime the sidebar is opened (or any other event handler). Later, i will need to implement link functionality on parts of the string. What is the best way to go about this? I have created an empty sidebar and just know the label element as of now. menu, and menuitem dont work. What other elements can i use to display text in a good way which supports dynamic contruction. Is there some good tutorial/sample extension which i can see and learn?

  • Get all email addresses in a string with JavaScript

    - by Mickel
    So, I have this JavaScript function: ME.Utils = { RxEmail: new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i), ValidateEmail: function(email) { return ME.Utils.RxEmail.test(email); }, GetEmailAddresses: function(text) { return text.match(ME.Utils.RxEmail); }, HasEmail: function(text) { return ME.Utils.GetEmailAddresses != null; } }; ValidateEmail works very well. However, HasEmail and GetEmailAddresses is not working properly. GetEmailAdresses always returns null, except for when the string only contains an email address. In this case, GetEmailAdresses returns an array not only containing the email address, but the email address ([email protected]), just the id (test) plus some unidentified etc. etc... Can you help me figure out what's wrong in my expression?

  • Question about memory allocation when initializing char arrays in C/C++.

    - by Carlos Nunez
    Before anything, I apologize if this question has been asked before. I am programming a simple packet sniffer for a class project. For a little while, I ran into the issue where the source and destination of a packet appeared to be the same. For example, the source and destination of an Ethernet frame would be the same MAC address all of the time. I custom-made ether_ntoa(char *) because Windows does not seem to have ethernet.h like Linux does. Code snippet is below: char *ether_ntoa(u_char etheraddr[ETHER_ADDR_LEN]) { int i, j; char eout[32]; for(i = 0, j = 0; i < 5; i++) { eout[j++] = etheraddr[i] >> 4; eout[j++] = etheraddr[i] & 0xF; eout[j++] = ':'; } eout[j++] = etheraddr[i] >> 4; eout[j++] = etheraddr[i] & 0xF; eout[j++] = '\0'; for(i = 0; i < 17; i++) { if(eout[i] < 10) eout[i] += 0x30; else if(eout[i] < 16) eout[i] += 0x57; } return(eout); } I solved the problem by using malloc() to have the compiler assign memory (i.e. instead of char eout[32], I used char * eout; eout = (char *) malloc (32);). However, I thought that the compiler assigned different memory locations when one sized a char-array at compile time. Is this incorrect? Thanks! Carlos Nunez

  • Good reasons to pass paths as strings instead of using DirectoryInfo/FileInfo

    - by neodymium
    In my new code I am not using strings to pass directory paths or file names. Instead I am using DirectoryInfo and FileInfo as they seem to encapsulate a lot of information. I have seen a lot of code that uses strings to pass directory information then they "split" and "mid" and "instr" in long incomprehensible statements until they get the part of the directory they are looking for. Is there any good reason to pass paths as strings?

  • Haskell: variant of `show` that doesn't wrap String and Char in quotes

    - by Joey Adams
    I'd like a variant of show (let's call it label) that acts just like show, except that it doesn't wrap Strings in " " or Chars in ' '. Examples: > label 5 "5" > label "hello" "hello" > label 'c' "c" I tried implementing this manually, but I ran into some walls. Here is what I tried: {-# LANGUAGE FlexibleInstances #-} {-# LANGUAGE UndecidableInstances #-} module Label where class (Show a) => Label a where label :: a -> String instance Label [Char] where label str = str instance Label Char where label c = [c] -- Default case instance Show a => Label a where label x = show x However, because the default case's class overlaps instance Label [Char] and instance Label Char, those types don't work with the label function. Is there a library function that provides this functionality? If not, is there a workaround to get the above code to work?

  • Having an @ inside of a string - PHP

    - by Msencenb
    So I know that you use a backslash to escape most things in php however the @ symbol is an operator that suppresses error messages. I'm trying to put an email string like this inside of an array "[email protected]", however php is throwing an error. How do you escape the @ sign? EDIT: Here is the code example that was throwing the error: $arr = array(3=> "[email protected]",4=> "[email protected]"); However replacing the double quotes with single quotes fixes the error as answered below.... why is that true?

  • Given a Member Access lambda expression, convert it to a specific string representation with full ac

    - by Nathan
    Given an Expression<Func<T, object>> (e.g. x = x.Prop1.SubProp), I want to create a string "Prop1.SubProp" for as deep as necessary. In the case of a single access (e.g. x = x.Prop1), I can easily do this with: MemberExpression body = (expression.Body.NodeType == ExpressionType.Convert) ? (MemberExpression)((UnaryExpression)expression.Body).Operand : (MemberExpression)expression.Body; return body.Member.Name; However, if there is deeper nesting, e.g. x = x.Prop1.SubProp1, this only gets the most deeply nested name, e.g. "SubProp1" instead of "Prop1.SubProp1" Is there anyway to access the full property path of a lambda expression?

  • XSD string pattern independent of leading/trailing space

    - by AndiDog
    I have a XSD simple type that should match UUIDs: <simpleType name="UuidT"> <restriction base="string"> <pattern value="[a-f0-9]{8}-[a-f0-9]{4}-[a-f0-9]{4}-[a-f0-9]{4}-[a-f0-9]{12}" /> </restriction> </simpleType> It correctly matches the following content: <!-- valid --> <Uuid>12345678-1234-5678-9012-123456789012</Uuid> But it doesn't match content that contains excess whitespace: <!-- not valid --> <Uuid> 2de25a81-b117-4b2a-b910-50f0878884f7 </Uuid> Sure, I could add \s* to both sides of the regex, but isn't there a simpler solution in XSD?

  • Sending an array of complex objects in the get string in C# ASP.NET MVC

    - by Mr Snuffle
    Hi, I want to send an array of objects in the get request string. I know this isn't the optimal solution, but I really just want to get this up and running. If I have a class, something like this public class Data { public int a { get; set; } public int b { get; set; } } public class RequestViewData { public IList<Data> MyData { get; set; } } I thought I could bind the MVC route to a web request like this http://localhost:8080/Request?MyData[0].a=1&MyData[0].b=2&MyData[1].a=3&[MyData[1].b=4 But all this does is create an array of two data objects without populating the values 1,2, 3 or 4. Is there a way to bind complex objects arrays?
