• Would this rollback/stop all records from inserting?

  - by chobo2

  Hi I been going through this tutorial http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx and them make a SP like this CREATE PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO TBL_TEST_TEST(NAME) SELECT XMLProdTable.NAME FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable EXEC sp_xml_removedocument @hDoc Now my requirements require me to mass insert and mass update one after another. So first I am wondering can I merge those into one SP? I am not sure how it works with this OPENXML but I would think it would just be making sure that the XPath is right. Next what happens while it would be running this combined SP and something goes wrong. Would it roll back all the records or just stop and the records that happened before this event that crashed it would be inserted?

• Why are Java primitive types' modifiers `public`, `abstract`, & `final`?

  - by oconnor0

  In the process of doing some reflection on Java types, I came across an oddity that I do not understand. Inspecting int for its modifiers returns public, abstract, and final. I understand public and final, but the presence of abstract on a primitive type is non-obvious to me. Why is this the case? Edit: I am not reflecting on Integer but on int: import java.lang.reflect.Modifier; public class IntegerReflection { public static void main(final String[] args) { System.out.println(String.format("int.class == Integer.class -> %b", int.class == Integer.class)); System.out.println(String.format("int.class modifiers: %s", Modifier.toString(int.class.getModifiers()))); System.out.println(String.format("Integer.class modifiers: %s", Modifier.toString(Integer.class.getModifiers()))); } } The output when run: int.class == Integer.class -> false int.class modifiers: public abstract final Integer.class modifiers: public final

• Permutations in python 2.5.2

  - by flpgdt

  Hi, I have a list of numbers for input, e.g. 671.00 1,636.00 436.00 9,224.00 and I want to generate all possible sums with a way to id it for output, e.g.: 671.00 + 1,636.00 = 2,307.00 671.00 + 436.00 = 1,107.00 671.00 + 9,224.00 = 9,224.00 671.00 + 1,636.00 + 436.00 = 2,743.00 ... and I would like to do it in Python My current constrains are: a) I'm just learning python now (that's part of the idea) b) I will have to use Python 2.5.2 (no intertools) I think I have found a piece of code that may help: def all_perms(str): if len(str) <=1: yield str else: for perm in all_perms(str[1:]): for i in range(len(perm)+1): #nb str[0:1] works in both string and list contexts yield perm[:i] + str[0:1] + perm[i:] ( from these guys ) But I'm not sure how to use it in my propose. Could someone trow some tips and pieces of code of help? cheers, f.

• TypoScript: {field:uid} replacement not working | Different CSS class per menu item

  - by Alex

  I have a header menu and try to define different CSS classes for each item. This is what I have: 20 = HMENU 20 { special = directory special.value = 107 1 = TMENU 1 { wrap = <ul class="foo" id="mymenu">|</ul> expAll = 1 NO = 1 NO.allWrap = <li class="first menu_{field:uid}">|</li> || <li class="menu_{field:uid}">|</li> || <li class="last menu_{field:uid}">|</li> } } But in the HTML output I simply get class="first menu_{field:uid}" and nothing is replaced.

• Can't edit IORegistryEntry

  - by yangumi

  Hi, I am creating a software on Mac and I would like to change the value of an IORegistryEntry. I can view it on the IORegistryExplorer, but I can't edit it. So it's my understanding that I have to edit it via code. Here is my code: CFMutableDictionaryRef matchingDict = IOServiceNameMatching("AppleUSBMultitouchDriver"); io_service_t service = IOServiceGetMatchingService(kIOMasterPortDefault, matchingDict); if(service) { CFStringRef manufacturer = IORegistryEntryCreateCFProperty(service, CFSTR("Manufacturer"), kCFAllocatorDefault,0); NSLog(@"%@", (NSString*)manufacturer); kern_return_t err = IORegistryEntrySetCFProperty(service, CFSTR("Manufacturer"), CFSTR("test")); NSLog(@"error = %d", err); } This will output 2010-04-10 16:09:09.015 Test[41548:a0f] Apple Inc. 2010-04-10 16:09:09.015 Test[41548:a0f] error = 0 But after I check the value in the IORegistryExplorer, it still doesn't change. Does anybody have any suggestions? Thank you

• How do you manage web navigation info in your application?

  - by Dave

  I’m building an application where different users will have different menu items available to them depending on what they’ve paid for. There will also be multiple levels to the menu hierarchy. What’s the best approach to this problem? I’m assuming I need a database table that represents the menu hierarchy, including the parent-child relationships of the nodes in the navigation as well as the sorting of the items. Then another table which I use to manage whether a user is authorized to access a particular item in that table. When I render the view, I’d reference the menus, and the access rights of the user to output the menu, and I’d also need a function to check that same authorization from each controller in case a user manually types in a URL of a controller they’re not supposed to have access to. Is this the right approach? Any suggestions for caching this to prevent the constant look-ups of this type of info? I’m open to any suggestions on how you may have approached this type of requirement.

• Bash intercepting wildcard in script

  - by MrRoth

  I am using Bash script to read line by line from a text file, which has special characters in it (regular expression). When I use echo "${SOME_VAR}" it does not display the text as is. I am familiar with Prevent * to be expanded in the bash script. How can I display and use the text as is? UPDATE The text (TSV) file holds tuples similar to (the last entry is a psql query) bathroom bathroom select name from photos where name ~* '\mbathroom((s)?|(''s)?)\M'; I am reading the CSV as follows: tail -n+2 text.file | while IFS=$'\t' read x y z do echo "${z}" done which gives the output select name from photos where name ~* 'mbathroom((s)?|(''s)?)M'); note that the '\' is missing

• Scraping non-absolute URL

  - by cooldude

  I am trying to scrape www.weather.bm. I want all 10 radar images, but I can only get one (the image updates regularly) and it's not a absolute image url. I was hoping I could use the image as a image slideshow like the link but dont know how. Also, how can I remove images/Radarlegend.png? I just need the radar images. Here is my code: include('simple_html_dom.php'); $html = file_get_html('http://www.weather.bm/radarMobile.asp'); foreach($html->find('img') as $element) echo $element->src . '<br>' My output is: <div id="main"> images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1556.jpg<br>images/Radarlegend.png<br></div> </div>

• How to update a library in my application

  - by andho

  I have used a library like ZendFramework in my project which I have put in Subversion. Now I want to update the version that I have put in Subversion. What's the best way to do this? Copying, taking a svn diff and patching the working copy or just copying the new files over the old files? I have tried svn diff with svn diff but this doesn't output anything. Normal diff outputs some stuff but it also considers the .svn directories.

• How do I implement an higher lower game algorithm?

  - by lazorde

  The computer will guess a player’s number between 1 and 100. After each guess the human player should respond “higher”, “lower” or “correct”. Your program should be able to guess the player’s number in no more than 7 tries. Begin by explaining the game to the player, telling him/her to think of a number between 1 and 100. Make the computer do what you would normally do to guess a number in a certain range. Allow the user to respond with “higher”, “lower”, or “correct” after each computer guess. Output the number of tries it took the computer to guess the number. Make the game as user friendly as you can.

• Is it possible to open a pipe-based filehandle which prints to a variable in perl?

  - by blackkettle

  Hi, I know I can do this, ------ open(F,"",\$var); print F "something cool"; close(F); print $var; ------ or this, open(F, "| ./prog1 | ./prog2 tmp.file"); print F "something cool"; close(F); but is it possible to combine these? The semantics of what I'd like to do should be clear from the following, open(F,"|./prog1 | ./prog2", \$var); print F "something cool"; close(F); print $var; however the above clearly won't work. A few minutes of experimenting and googling seems to indicate that this is not possible, but I'd like to know if I'm stuck with using the `` to capture the output.

• PHP: find 2 or more numbers from a list of N numbers that can add up towards a given ammount

  - by Splash

  Hi Guys, I am trying to create a little php script that can make my life a bit easier. Basically, I am going to have 21 text fields on a page where I am going to input 20 different numbers. In the last field I will enter a number let's call it the TOTAL AMMOUNT. All I want the script to do is to point out which numbers from the 20 fields added up will come up to TOTAL AMMOUNT. Example: field1= 25.23 field2= 34.45 field3= 56.67 field4= 63.54 field5= 87.54 .... field20= 4.2 Total Ammount= 81.90 Output: field1+fields3=81.90 Some of the fields might have 0 as value because sometimes I only need to enter 5-15 fields and the maximum will be 20. If someone can help me out with the php code for this, will be greatly appreciated.

• PHP getting a bunch of weird code \u0644\u064a\u0646\u0643 \u0627\u0644

  Hello I'm getting a bunch of weird html output in users messages e.g. \u0644\u064a\u0646\u0643 \u0627\u0644 \u0639\u0627\u0645\u0644 I assume their aribic characters decoded? How can I perhaps preg replace all these codes with something a little more useful? because search results are filled with pages and pages of this stuff Perhaps even display them as they're supposed to be? Any advice what to do with such strings and how to implement them appreciated.. Please keep in mind this stuff is mixed in been common language letters / numbers many thanks

• Programmatically check whether a linux kernel module exists or not at runtime

  - by dgraziotin

  I am writing a C daemon, which depends on the existence of two kernel modules in order to do its job. The program does not directly use these (or any other) modules. It only needs them to exist. Therefore, I would like to programmatically check whether these modules are already loaded or not, in order to warn the user at runtime. Before I start to do things like parsing /proc/modules or lsmod output, does a utility function already exist somewhere? Something like is_module_loaded(const char* name); I am pretty sure this has been asked before. However, I think I am missing the correct terms to search for this. Thanks!

• How can I compute the average cost for this solution of the element uniqueness problem?

  - by Alceu Costa

  In the book Introduction to the Design & Analysis of Algorithms, the following solution is proposed to the element uniqueness problem: ALGORITHM UniqueElements(A[0 .. n-1]) // Determines whether all the elements in a given array are distinct // Input: An array A[0 .. n-1] // Output: Returns "true" if all the elements in A are distinct // and false otherwise. for i := 0 to n - 2 do for j := i + 1 to n - 1 do if A[i] = A[j] return false return true How can I compute the average cost (i.e. number of comparisons for a given n) for this algorithm? What is a reasonable assumption about the input?

• why C clock() returns 0

  - by eddy ed

  I've got something like this: clock_t start, end; start=clock(); something_else(); end=clock(); printf("\nClock cycles are: %d - %d\n",start,end); and I always get as an output "Clock cycles are: 0 - 0" Any idea why this happens? (Just to give little detail, the something_else() function performs a left-to-right exponentiation using montgomery represantation, moreover I don't know for certain that the something_else() function does indeed take some not negligible time.) This is on Linux. The result of uname -a is: Linux snowy.*****.ac.uk 2.6.32-71.el6.x86_64 #1 SMP Fri May 20 03:51:51 BST 2011 x86_64 x86_64 x86_64 GNU/Linux

• created persisted computed columns when the user defined scalar function appears to be non-determini

  - by Ralph Shillington

  I have a scalar UDF that I know to be deterministic, however SQL doesn't. Is there a way to declare it as deterministic so that I can then use it in a persisted computed column definition? further clarification: The purpose of this exercise is that I need to harvest out specific values from an XML column on the row. I can't use the value method of the xml column in my computed column definition, but I can use it in a UDF. I know the xpath query in the value method will produce the same output give the same input so while I certainly understand that not all calls to value will be deterministic I want to assert that mine is.

• C struct print, decode this code?

  - by pauliwago

  I am in the process of studying for a test, and I'm trying to work through some practice problems. I've been working on this a while now..but can't figure it out. Please take a look at the code fragment: union { int i; short x; unsigned short u; float f; } testout; testout.i=0xC0208000; Before I ask the question, can someone please explain to me how the above code works?? My guess is that testout.i=0xC0208000 puts either an int, short, unsigned short, or float and puts the result in that address. (?) The question is what prints out if we write printf("%d", testout.x)? I know we should expect digits....but I have no idea where they are getting the digits from....there is no output. Any explanation would be greatly appreciated. Thanks!
