• User Mode Linux - Installing a module error

  - by Zach

  I am trying to run 'make' on a module in User Mode Linux to install a simple makefile. Here is my make file: obj-m := hello.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules When I run this in User Mode Linux I get the following error: make[1]: Entering directory /lib/modules/2.6.28/build' make[1]: *** No rule to make targetmodules'. Stop. make[1]: Leaving directory `/lib/modules/2.6.28/build' make: * [default] Error 2 The problem is that no files are present under /lib/modules/. There's no directory for 2.6.28 or build. From what I've read, these should be symlinks to /usr/src, but under /usr/src, I don't see any files under that either.

• How to open window pop-up from Silverlight Out-of-Browser?

  - by Jeaffrey Gilbert

  I need to open window pop-up from Silverlight Out-of-Browser application. I've added parameter <param name="enablehtmlaccess" value="true" /> in Index.html, but executing this from code behind: HtmlPage.Window.Navigate(new Uri(myUrl), "_blank", myFeatures); still returns error: Silverlight OOB Error: The DOM/scripting bridge is disabled. I've read about this post, does it mean that I can't open pop-up from OOB? Why I need to do this, because actually I've shown the HTML page in OOB Silverlight by WebBrowser control within ChildWindow but when I click an anchor in HTML page, which linked to _blank page, it jumps to my default browser. It doesn't meet the requirement, except launch that HTML index page also in default browser at the first time, triggered from button control in OOB Silverlight. Is that possible? Please advice, thanks.

• Why does this break statement break not work?

  - by Roman

  I have the following code: public void post(String message) { final String mess = message; (new Thread() { public void run() { while (true) { try { if (status.equals("serviceResolved")) { output.println(mess); Game.log.fine("The following message was successfully sent: " + mess); break; } else { try {Thread.sleep(1000);} catch (InterruptedException ie) {} } } catch (NullPointerException e) { try {Thread.sleep(1000);} catch (InterruptedException ie) {} } } } }).start(); } In my log file I find a lot of lines like this: The following message was successfully sent: blablabla The following message was successfully sent: blablabla The following message was successfully sent: blablabla The following message was successfully sent: blablabla And my program is not responding. It seems to me that the break command does not work. What can be a possible reason for that. The interesting thing is that it happens not all the time. Sometimes my program works fine, sometimes the above described problem happens.

• Speech Recognition Server Does Not Stay Open

  - by Waffle

  I am trying to create a simple program that loops for user speech input using com.apple.speech.recognitionserver. My code thus far is as follows: set user_response to "start" repeat while user_response is not equal to "Exit" tell application id "com.apple.speech.recognitionserver" set user_response to listen for {"Time", "Weather", "Exit"} with prompt "Good Morning" end tell if user_response = "Time" then set curr_time to time string of (the current date) set curr_day to weekday of (the current date) say "It is" say curr_time say "on" say curr_day say "day" else if user_response = "Weather" then say "It is hot outside. What do you expect?" end if end repeat say "Have a good day" If the above is run on my system it says good morning and it then pops up with the speech input system and waits for either Time, Weather, or Exit. They all do what they say they are going to do, but instead of looping if I say Time and Weather and asking again until I say exit the speechserver times out and never pops up again. Is there a way of either keeping that application open until the program ends or is applescript not capable of looping for user speech input?

• 500 error on function call in Codeigniter

  - by Ilia Lev

  I am using just installed CI 2.1.3 Following phpacademy tutorial I wrote in the routes.php: $route['default_controller'] = "site"; (instead of: $route['default_controller'] = "welcome";) and in controllers/site.php: <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class Site extends CI_Controller { public function index() { echo "default function started.<br/>"; } public function hello(){ echo "hello function started.<br/>"; } } After uploading it to the server and going to the [www.mydomain.ext] it works ok (writes: "default function started.") BUT if I add 'this-hello();' to the index() function it throws a 500 error. Why does it happen and how can I resolve this? Thank you in advance.

• ORDER BY giving wrong order

  - by Cody Dull

  I have an SQL statement in my C# program that looks like: SELECT * FROM XXX.dbo.XXX WHERE Source = 'OH' AND partnum = '1231202085' ORDER BY partnum, Packaging, Quantity When running this query in SQL Server Management, the results are ordered as expected. My first 3 results have the same partnum and Packaging with Quantities of 32.0, 50.8, and 51.0. However, when I run the query from my program, the result set with quantity 50.8 is the first to be returned. The datatype of Quantity is decimal(18,9). I've tried cast, it doesn't appear to be a datatype problem. I cant figure out why its getting the middle quantity.

• how to set breakpoint on function in a shared library which has not been loaded in gdb

  - by pierr

  Hi, I have a shared library libtest.so which will be loaded into the the main program using dlopen. Function test() reside in libtest.so and will be called in the main program through dlsym. Is there any way I could set up a break point on test? Please note that the main programm has not been linked to libtest.so during linking time. Otherwise , I should be able to set the break point although it is a pending action. In my case, when I do b test, gdb will tell me Function "test" not defined.

• Expression Encoder SDK - WMA Pro Codec Issues with Windows Server 2003

  - by PortageMonkey

  I am using the Expression Encoder SDK to encode .avi and Flash files to a .wmv format suitable for Silverlight. By default, EE encodes files with audio using the the WMA PRO codec. If you are running Windows Server 2003, this is a problem as it doesn't support the WMA PRO codec and produces and error message similar to the following. Error Message: The Audio Profile settings do not match a valid system profile. Error Source: Microsoft.Expression.Encoder Error Target Site: System.String GetProfileString() I am looking for a way to change the default audio codec to something suitable for WS 2003. I am aware that although not supported natively, there is a highly invasive way to install Windows Media Player 11 and it's codecs on WS 2003 but this involves registry tinkering and other hacks not suitable for our production environments so that solution is out.

• how to remove a few lines from a Unicode registry file using batch commands in Windows?

  - by Cosmin

  Hi. I have a program who's generating some data in registry. I save it with "reg export HKCU\Software\ProgramName\Data data.reg" (Unicode format). I need to take it to other computer and import it there so the program from that computer could use the data. But I have to remove some text lines from data.reg. The text lines are easy to find because they contain some strings. Now I'm doing this manually (using Wordpad) every few days but maybe there is another way... Oh and I can't install other programs on these computers (the access is restricted) so I have to use batch/cmd files. What I tried so far: - redirecting the export to "con" but is visual only not in a variable; - using "for /F ..." but this works only with ANSI and removes blank lines. Can somebody please help me...? Thank you.

• create a list of threads in C

  - by Hristo

  My implementation (in C) isn't working... the first node is always NULL so I can't free the memory. I'm doing: thread_node_t *thread_list_head = NULL; // done in the beginning of the program ... // later on in the program thread_node_t *thread = (thread_node_t*) malloc(sizeof(thread_node_t)); pthread_create(&(thread->thread), NULL, client_thread, &csFD); thread->next = thread_list_head; thread_list_head = thread; So when I try to free this memory, thread_list_head is NULL. while (thread_list_head != NULL) { thread_node_t *temp = thread_list_head; thread_list_head = thread_list_head->next; free(temp); temp = NULL; } Any advice on how to fix this or just a new way to create this list that would work better? Thanks, Hristo

• Does this mySQL Stored Procedure Work?

  - by Laxmidi

  Hi, I got the following stored procedure from http://dev.mysql.com/doc/refman/5.1/en/functions-that-test-spatial-relationships-between-geometries.html Does this work?

If this one works, then I'll try to figure out how to call it in php instead. Thanks, Laxmidi

• SQL "JOIN" vs. "INNER JOIN"?

  - by froadie

  I recently came across a query that implements a join using just the "JOIN" keyword. On researching I saw that when using a join in SQL without specifying INNER or OUTER, the default is an INNER JOIN. I've never come across this syntax before; all the SQL I've written/read/worked with specifies INNER or some sort of OUTER (LEFT, RIGHT, FULL...). Is there any reason not to rely on the default? Is the plain JOIN widely used? What are the coding standards regarding JOIN vs. INNER JOIN?

• python optparse, how to include additional info in usage output?

  - by CarpeNoctem

  Using python's optparse module I would like to add extra example lines below the regular usage output. My current help_print() output looks like this: usage: check_dell.py [options] options: -h, --help show this help message and exit -s, --storage checks virtual and physical disks -c, --chassis checks specified chassis components I would like it to include usage examples for the less *nix literate users at my work. Something like this: usage: check_dell.py [options] options: -h, --help show this help message and exit -s, --storage checks virtual and physical disks -c, --chassis checks specified chassis components Examples: check_dell -c all check_dell -c fans memory voltage check_dell -s How would I accomplish this? What optparse options allow for such? Current code: import optparse def main(): parser = optparse.OptionParser() parser.add_option('-s', '--storage', action='store_true', default=False, help='checks virtual and physical disks') parser.add_option('-c', '--chassis', action='store_true', default=False, help='checks specified chassis components') (opts, args) = parser.parse_args()

• Are large include files like iostream efficient? (C++)

  - by Keand64

  Iostream, when all of the files it includes, the files that those include, and so on and so forth, adds up to about 3000 lines. Consider the hello world program, which needs no more functionality than to print something to the screen: #include <iostream> //+3000 lines right there. int main() { std::cout << "Hello, World!"; return 0; } this should be a very simple piece of code, but iostream adds 3000+ lines to a marginal piece of code. So, are these 3000+ lines of code really needed to simply display a single line to the screen, and if not, do they create a less efficient program than if I simply copied the relevant lines into the code?

• UITableViewCellStyleDefault label width

  - by Rob Bonner

  Hello all, I am getting some odd behavior from stock table cells, or maybe not odd, maybe I am making some assumptions. I create the cells as follows: cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; Then I assign an image to the default imageView property. My image usually comes in from a user, so it might be larger than the default size. To take care of this I: [cell.imageView setContentMode:UIViewContentModeScaleAspectFit]; which I expected to scale the image for me within the control, but in reality, the images are all over the map. So, is there a proper way to constrain the image in stock cell types? Thanks in advance!

• GUI freezing after datagridviews have been updated using backgroundworkers

  - by Jhon

  I have made an application which runs three backgroundworkers simultaneously. It basically updates three datagridviews, which it is doing spot on. My problem is if I press maximizebox button or anywhere in any of the datagridview the program hangs for quite a long time. I am able to use the horizontal scroll but not vertical scrolls. I have tried Backgroundworker_runworkercompleted and it fires as required after threads have updated their respective datagridviews. Is it a normal behaviour or am i doing something wrong any suggestions would be helpful. P.S: I have run the whole program using step method and their is no infinite loop in the code. Thanks in advance Jhon

• Parsing language for both binary and character files

  - by Thorsten S.

  The problem: You have some data and your program needs specified input. For example strings which are numbers. You are searching for a way to transform the original data in a format you need. And the problem is: The source can be anything. It can be XML, property lists, binary which contains the needed data deeply embedded in binary junk. And your output format may vary also: It can be number strings, float, doubles.... You don't want to program. You want routines which gives you commands capable to transform the data in a form you wish. Surely it contains regular expressions, but it is very good designed and it offers capabilities which are sometimes much more easier and more powerful. Something like a super-grep which you can access (!) as program routines, not only as tool. It allows: joining/grouping/merging of results inserting/deleting/finding/replacing write macros which allows to execute a command chain repeatedly meta-grouping (lists-tables-hypertables) Example (No, I am not looking for a solution to this, it is just an example): You want to read xml strings embedded in a binary file with variable length records. Your tool reads the record length and deletes the junk surrounding your text. Now it splits open the xml and extracts the strings. Being Indian number glyphs and containing decimal commas instead of decimal points, your tool transforms it into ASCII and replaces commas with points. Now the results must be stored into matrices of variable length....etc. etc. I am searching for a good language / language-design and if possible, an implementation. Which design do you like or even, if it does not fulfill the conditions, wouldn't you want to miss ? EDIT: The question is if a solution for the problem exists and if yes, which implementations are available. You DO NOT implement your own sorting algorithm if Quicksort, Mergesort and Heapsort is available. You DO NOT invent your own text parsing method if you have regular expressions. You DO NOT invent your own 3D language for graphics if OpenGL/Direct3D is available. There are existing solutions or at least papers describing the problem and giving suggestions. And there are people who may have worked and experienced such problems and who can give ideas and suggestions. The idea that this problem is totally new and I should work out and implement it myself without background knowledge seems for me, I must admit, totally off the mark.

I have found the average but I can't seem to figure out how to find the lowest and highest grade. Can you please show me pr tell me what to do?

• How can I re-size and re-position a shadowbox/greybox window to display in a certain div element?

  - by kielie

  Hi guys, I would like to know if it is possible to re-size and re-position a greybox or shadowbox window to display in a certain div element? I am creating a template for a wordpress site, and I am using the default calendar, but when you click on a date inside of the calendar, the default action is to open it up in a new window. Would it be possible to mod greybox or shadowbox in such a way that when you click on a date, the box opens up over the calendar displaying the contents in it, instead of a new page? Or is there another way of achieving the desired result, maybe with jQuery or Javascript? Any help would be greatly appreciated, thanx in advance!
