• How to call 3 threads sequentially many times?

  - by Hello

  How to call 3 threads sequentially many times? For example: In iteration 1, execution order should be "Thread0-thread1-thread2" then in iteration 2 should be same i.e "Thread0 - thread1-thread2" and so on. The sample code is just executing 3 threads only once. It is not going to 2nd iteration. Thread0 = CreateThread( NULL,0,ThreadProc0, NULL, CREATE_SUSPENDED, &ThreadID); Thread1 = CreateThread( NULL,0,ThreadProc1, NULL, CREATE_SUSPENDED, &ThreadID); Thread2 = CreateThread( NULL,0,ThreadProc2, NULL, CREATE_SUSPENDED, &ThreadID); for(i=0;i<iterations;i++) //Iterations in calling threads { ResumeThread(Thread0); WaitForSingleObject(Thread0, INFINITE); ResumeThread(Thread1); WaitForSingleObject(Thread1, INFINITE); ResumeThread(Thread2); WaitForSingleObject(Thread2, INFINITE); } // Close thread and semaphore handles

• Linq to CSV select by column

  - by griegs

  If I have the following (sample) text file; year,2008,2009,2010 income,1000,1500,2000 dividends,100,200,300 net profit,1100,1700,2300 expenses,500,600,500 profit,600,1100,1800 Is there a way in Linq that I can select the expenses for 2010 only?

• Why hashCode() returns the same value for a object in all consecutive executions?

  - by Vijay Shanker

  Hi, I am trying some code around object equality in java. As I have read somewhere hashCode() is a number which is generated by applying the hash function. Hash Function can be different for each object but can also be same. At the object level, it returns the memory address of the object. Now, I have sample program, which I run 10 times, consecutively. Every time i run the program I get the same value as hash code. If hashCode() function returns the memory location for the object, how come the java(JVM) store the object at same memory address in the consecutive runs? Can you please give me some insight and your view over this issue?

• mktime and date questions..

  - by mjboggess

  Hello SO! I am working on a small project and am playing with date() and mktime() in PHP. Compare the two code blocks and their output, notice the second sample adds one to the month in it's first mktime. $monthis = 5; echo date('F', mktime(0,0,0,$monthis,0,0)) . " 1, 2010 is on a " . date("l F", mktime(0, 0, 0, $monthis, 1, 2010)); puts out April 1, 2010 is on a Saturday May but if I change it to $monthis = 5; echo date('F', mktime(0,0,0,$monthis + 1,0,0)) . " 1, 2010 is on a " . date("l F", mktime(0, 0, 0, $monthis, 1, 2010)); puts out May 1, 2010 is on a Saturday May Why do I have to add one to the month in the first mktime so that both emit the same month? Any help or clarity would be appreciated. Thanks :)

• ERROR: there is no parameter $1 when creating view

  - by idlemoments

  When we try to create a view within a funcion we get ERROR: there is no parameter $1. This is the sample code. Begin CREATE VIEW artikelnr AS SELECT datum, 'uitgifte' as "type", CASE WHEN 'test'='test' THEN 0 END as "aantal ontvangen", aantal as "aantal uitgegeven" FROM uitgifteregel JOIN artikel ON artikel.artikelnr = new.artikelnr JOIN uitgifte ON uitgifte.uitgiftenr = uitgifteregel.uitgiftenr UNION SELECT datum, 'ontvangst' as "type", aantal as "aantal ontvangen" , CASE WHEN 'test'='test' THEN 0 END as "aantal uitgegeven" FROM ontvangstregel JOIN artikel ON artikel.artikelnr = new.artikelnr JOIN ontvangst ON ontvangst.ontvangstnr = ontvangstregel.ontvangstnr; Return new; end; When we replace new.artikelnr on line 7 with value 1 it works like it should, but the function needs to work with different artikelnr's. example line 7: JOIN artikel ON artikel.artikelnr = new.artikelnr Please point us in the right direction.

• MySQL Multiple "AND" Query

  - by Mark J

  I have a table with 2 columns (see below). A member can have multiple responses to a question RESPONSES --------- member_id INT response_id INT SAMPLE DATA member_id -- response_id 1 -- 3 1 -- 5 2 -- 1 2 -- 5 2 -- 9 3 -- 1 3 -- 5 3 -- 6 What I need to do is query the table for member that meet ALL response criteria. For example I need to select all members that have a response_id of 1 AND 5. I am using the following query: SELECT DISTINCT member_id FROM responses WHERE response_id = 1 AND response_id = 5. I would expect to get back member_id's 2,3. However I am getting nothing returned. I used EXPLAIN and it shows there is an error in my where query. What am I doing wrong? Also, is there a function similar to IN where all the criteria must be met in order to return true? Thanks for your help.

• How can I loop through all the open instances of a particular form?

  - by raz3r

  I need to update a ListBox of a Form2 created dinamically. Let's say that in the event where I have to update this ListBox (in Form1 of course) I don't have a reference of this Form2 so I can't call the UpdateList method (and no, I can't make it static). I don't even know if there is a Form2 opened, it could be or not. What do you suggest? Is there a way to loop through all the open istances of Form2? Code Sample: //Form1 public void event() { //UPDATE FORM2 LISTBOX } //SOMEWHERE IN FORM1 Form2 runTime = new Form2(); //Form2 public void UpdateList() { //UPDATE LISTBOX }

• Can typeid() be used to pass a function?

  - by Kerb_z

  I tried this and got the output as: void Please explain the following Code: #include <cstdio> #include <typeinfo> using namespace std ; void foo() { } int main(void) { printf("%s", typeid(foo()).name());// Please notice this line, is it same as typeid( ).name() ? return 0; } AFAIK: The typeid operator allows the type of an object to be determined at run time. So, does this sample code tell us that a function that returns void is of *type void*. I mean a function is a method and has no type. Correct?

• how do I disable options based on the previous selection?

  - by 3r1c

  I have three drop-down menus for each sample shirt; product, colour and grade. Not all products are available in all colours and/or grades.

Unfortunately, I can't get it to work with an option-selected input. This is what I'm working on - quartus.ca/select-options.html Any guidance would be appreciated.

• Removing words from a file

  - by user1765792

  I'm trying to take a regular text file and remove words identified in a separate file (stopwords) containing the words to be removed separated by carriage returns ("\n"). Right now I'm converting both files into lists so that the elements of each list can be compared. I got this function to work, but it doesn't remove all of the words I have specified in the stopwords file. Any help is greatly appreciated. def elimstops(file_str): #takes as input a string for the stopwords file location stop_f = open(file_str, 'r') stopw = stop_f.read() stopw = stopw.split('\n') text_file = open('sample.txt') #Opens the file whose stop words will be eliminated prime = text_file.read() prime = prime.split(' ') #Splits the string into a list separated by a space tot_str = "" #total string i = 0 while i < (len(stopw)): if stopw[i] in prime: prime.remove(stopw[i]) #removes the stopword from the text else: pass i += 1 # Creates a new string from the compilation of list elements # with the stop words removed for v in prime: tot_str = tot_str + str(v) + " " return tot_str

• Structs and pointers

  - by user1763861

  I have a few questions about structs and pointers For this struct: typedef struct tNode_t { char *w; } tNode; How come if I want to change/know the value of *w I need to use t.w = "asdfsd" instead of t->w = "asdfasd"? And I compiled this successfully without having t.w = (char *) malloc(28*sizeof(char)); in my testing code, is there a reason why tt's not needed? Sample main: int main() { tNode t; char w[] = "abcd"; //t.word = (char *) malloc(28*sizeof(char)); t.word = w; printf("%s", t.word); } Thanks.

• Clojure: find repetition

  - by demi

  Let we have a list of integers: 1, 2, 5, 13, 6, 5, 7 and I want to find the first number has a duplicate before it and return a vector of two indices, In my sample, it's 5 at [2, 5]. What I did so far is loop, but can I do it more elegant, short way? (defn get-cycle [xs] (loop [[x & xs_rest] xs, indices {}, i 0] (if (nil? x) [0 i] ; Sequence is over before we found a duplicate. (if-let [x_index (indices x)] [x_index i] (recur xs_rest (assoc indices x i) (inc i)))))) No need to return number itself, because I can get it by index and, second, it may be not always there.

• One input file to multiple output files

  - by user1265669

  I found some helpful stuff on this site but my input file is different from the examples already posted and I cannot make the leap in an efficient manner. My input file looks like this: sample_dude data1 data2 data3 data4 sample_lady data5 data6 data7 data8 sample_dude data9 data10 data11 data12 sample_child data13 data14 data15 data16 I want to create a separate file for each sample with all the data columns. For example, one file would be called sample_dude.txt and look like this: data1 data2 data3 data4 data9 data10 data11 data12 There is an unknown number of samples but always just four data columns. Any help greatly appreciated. Thank you. PS: I'm trying to do this in python.

• quickflip + slideshow animation

  - by user288231

  I have been trying to integrate quickflip and a slideshow animation. So everytime when the user hovers over the image, it would pause the animation and "flip to the other side". When the user hovers out, it would then replace its normal state. The problem is here is I do not know how to handle the quickflip code (http://jonraasch.com/blog/quickflip-2-jquery-plugin). I have looked at the sample code and tried to replace it, but at the end the animations would get messed up... Javascript: var interval = setInterval( "slideSwitch()", 3000 ); $('.quickFlip').quickFlip(); $('#slideshow').hover(function () { clearInterval(interval); }, function () { interval = setInterval("slideSwitch()", 3000); });

• Humanizing time

  - by keruilin

  I have a number of products that are perishable. Therefore, each product has an attribute called hours_expiration that tells how many hours the product can be used before it goes bad. For ex, apple expires in 168 hours; nut expires in 4320 hours. Given, the product's hours-to-expiration and the current time (Time.now or Date.now), how can I humanize the time-to-expiration in some of the following sample ways? Your item is set to expire in about: 6 months and 14 days 1 month and 13 days 1 month and 1 day 27 days 1 day 23 hours 1 hour 50 minutes 1 minute Looking for something robust and simple!

• Codeigniter: how do I select count when `$query->num_rows()` doesn't work for me?

  - by mOrloff

  I have a query which is returning a sum, so naturally it returns one row. I need to count the number of records in the DB which made that sum. Here's a sample of the type of query I am talking about (MySQL): SELECT i.id, i.vendor_quote_id, i.product_id_requested, SUM(i.quantity_on_hand) AS qty, COUNT(i.quantity_on_hand) AS count FROM vendor_quote_item AS i JOIN vendor_quote_container AS c ON i.vendor_quote_id = c.id LEFT JOIN company_types ON company_types.company_id = c.company_id WHERE company_types.company_type = 'f' AND i.product_id_requested = 12345678 I have found and am now using the select_min(), select_max(), and select_sum() functions, but my COUNT() is still hard-coded in. The main problem is that I am having to specify the table name in a tightly coupled manner with something like $this->$db->select( 'COUNT(myDbPrefix_vendor_quote_item.quantity_on_hand) AS count' ) which kills portability and makes switching environments a PIA. How can/should I get my the count values I am after with CI in an uncoupled way??

• GWT 100% height panel with scroll

  - by Andrey

  Hello! Could anyone help me make normal layout in GWT. I need a main panel which: fills all the browser space (100% height); if being collapsed too much shows scroll bars (autoscroll). When I use old layout (RootPanel, VerticalPanel) I have scroll, but can't get 100% height. When I use new layout (RootLayoutPanel, DockLayoutPanel) I get 100% height, but I don't get any scroll. And also I have some troubles in IE. Is there any sample showing how to achieve both goals? Thanks in advance!

• Determining smallest number of samples for 99% accuracy

  - by test

  I'm trying to compare 100,000 records on a local database (L) with 100,000 records on a remote database (R). Basically I want to know if an elment in L exusts in R. To determine that, I have to make a request against the R for each L, which takes a long time (I know, there should be a better way, there isn't, that's the API I've got). So I would like to test a small sample of L against R, and then infer with some level of confidence how many are present in the whole R. How many do I have to test to have a 99% confidence level?

• The Oracle Enterprise Linux Software and Hardware Ecosystem

  - by sergio.leunissen

  It's been nearly four years since we launched the Unbreakable Linux support program and with it the free Oracle Enterprise Linux software. Since then, we've built up an extensive ecosystem of hardware and software partners. Oracle works directly with these vendors to ensure joint customers can run Oracle Enterprise Linux. As Oracle Enterprise Linux is fully--both source and binary--compatible with Red Hat Enterprise Linux (RHEL), there is minimal work involved for software and hardware vendors to test their products with it. We develop our software on Oracle Enterprise Linux and perform full certification testing on Oracle Enterprise Linux as well. Due to the compatibility between Oracle Enterprise Linux and RHEL, Oracle also certifies its software for use on RHEL, without any additional testing. Oracle Enterprise Linux tracks RHEL by publishing freely downloadable installation media on edelivery.oracle.com/linux and updates, bug fixes and security errata on Unbreakable Linux Network (ULN). At the same time, Oracle's Linux kernel team is shaping the future of enterprise Linux distributions by developing technologies and features that matter to customers who deploy Linux in the data center, including file systems, memory management, high performance computing, data integrity and virtualization. All this work is contributed to the Linux and Xen communities. The list below is a sample of the partners who have certified their products with Oracle Enterprise Linux.
