  • C# : Number Conversion Problem

    - by Sayem Ahmed
    Today I faced a strange problem in C#. I have an ASP.NET page where user can enter certain price, quantity etc. I get the price value, convert it to double, then multiply it with 100 and then typecast it to an integer. When the price is "33.30", after converting it to double it remains 33.3 (obviously...), but after multiplying it with 100, it becomes 3329.9999999999995, and when I cast it to integer by applying simple cast operator "(int) (price * 100) ", it becomes 3329. Right now I have no idea why this is happening. So I thought may be you guys can help :) .

  • Wordpress show next 3 x number adjacent custom posts from existing

    - by user2463284
    On a single/detail Custom Post Page I would like to display a custom nav of li's or divs in a sidebar that displays both title, excerpt and permalink for the next 3 posts within the custom post series. So if we are on custom post 3 then it would show 4, 5, 6 in the sidebar. The closest I've found to this is :-= global $post; $current_post = $post; // remember the current post for($i = 1; $i <= 3; $i++){ $post = get_previous_post(); // this uses $post->ID setup_postdata($post); // do your stuff here the_title(); } $post = $current_post; // restore Problem is this only shows the first next post and I need to show 3. Thanks Glennyboy

  • Large number of UPDATE queries slowing down page

    - by Bryan Lewis
    I am reading and validating large fixed-width text files (range from 10-50K lines) that are submitted via our ASP.net website (coded in VB.Net). I do an initial scan of the file to check for basic issues (line length, etc). Then I import each row into a MS SQL table. Each DB rows basically consists of a record_ID (Primary, auto-incrementing) and about 50 varchar fields. After the insert is done, I run a validation function on the file that checks each field in each row based on a bunch of criteria (trimmed length, isnumeric, range checks, etc). If it finds an error in any field, it inserts a record into the Errors table, which has an error_ID, the record_ID and an error message. In addition, if the field fails in a particular way, I have to do a "reset" on that field. A reset might consist of blanking the entire field, or simply replacing the value with another value (e.g. replacing the string with a new one that has all illegals chars taken out). I have a 5,000 line test file. The upload, initial check, and import takes about 5-6 seconds. The detailed error check and insert into the Errors table takes about 5-8 seconds (this file has about 1200 errors in it). However, the "resets" part takes about 40-45 seconds for 750 fields that need to be reset. When I comment out the resets function (returning immediately without actually calling the UPDATE stored proc), the process is very fast. With the resets turned on, the pages take 50 seconds to return. My UPDATE stored proc is using some recommended code from http://sommarskog.se/dynamic_sql.html, whereby it uses CASE instead of dynamic SQL: UPDATE dbo.Records SET dbo.Records.file_ID = CASE @field_name WHEN 'file_ID' THEN @field_value ELSE file_ID END, . . (all 50 varchar field CASE statements here) . WHERE dbo.Records.record_ID = @record_ID Is there any way I can help my performance here. Can I somehow group all of these UPDATE calls into a single transaction? Should I be reworking the UPDATE query somehow? Or is it just sheer quantity of 750+ UPDATEs and things are just slow (it's a quad proc server with 8GB ram). Any suggestions appreciated.

  • Limit Annotation number in Mapkit

    - by teddafan
    Hi all, I want to stop my app from loading more annotations after they are all added ( they are added by the user one by one). How would you do that? the following code is what i think is important (void) loadAndSortPOIs { [poiArray release]; nextPoiIndex = 0; NSString *poiPath = [[NSBundle mainBundle] pathForResource:@"pois" ofType:@"plist"]; poiArray = [[NSMutableArray alloc] initWithContentsOfFile:poiPath]; CLLocation *homeLocation = [[CLLocation alloc] initWithLatitude:homeCoordinate.latitude longitude:homeCoordinate.longitude]; for (int i = 0; i < [poiArray count]; i++) { NSDictionary *dict = (NSDictionary*) [poiArray objectAtIndex: i]; CLLocationDegrees storeLatitude = [[dict objectForKey:@"workingCoordinate.latitude"] doubleValue]; CLLocationDegrees storeLongitude = [[dict objectForKey:@"workingCoordinate.longitude"] doubleValue]; CLLocation *storeLocation = [[CLLocation alloc] initWithLatitude:storeLatitude longitude:storeLongitude]; CLLocationDistance distanceFromHome = [storeLocation getDistanceFrom: homeLocation]; NSMutableDictionary *mutableDict = [[NSMutableDictionary alloc] initWithDictionary:dict]; [mutableDict setValue:[NSNumber numberWithDouble:distanceFromHome] forKey:@"distanceFromHome"]; [poiArray replaceObjectAtIndex:i withObject:mutableDict]; [mutableDict release]; } [homeLocation release]; // now sort by distanceFromHome NSArray *sortDescriptors = [NSArray arrayWithObject: [[NSSortDescriptor alloc] initWithKey: @"distanceFromHome" ascending: YES]]; [poiArray sortUsingDescriptors:sortDescriptors]; NSLog (@"poiArray: %@", poiArray); } Thank you for your help.

  • Monotouch/C# version of "stringWithContentsOfUrl"

    - by Pselus
    I'm trying to convert a piece of Objective-C code into C# for use with Monotouch and I have no idea what to use to replace stringWithContentsOfUrl Should I use something like: HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://www.helephant.com"); HttpWebResponse response = (HttpWebResponse) request.GetResponse(); if (response.StatusCode == HttpStatusCode.OK && response.ContentLength > 0){ TextReader reader = new StreamReader(response.GetResponseStream()); string text = reader.ReadToEnd(); Console.Write(text); } Is that even safe to use in MonoTouch? Will it work for the iPhone?

  • Accepts Nested Attributes For - edit form displays incorrect number of items ( + !map:ActiveSupport:

    - by Brightbyte8
    Hi, I have a teacher profile model which has many subjects (separate model). I want to add subjects to the profile on the same form for creating/editing a profile. I'm using accepts_nested_attributes for and this works fine for creation. However on the edit page I am getting a very strange error - instead of seeing 3 subjects (I added three at create and a look into the console confirms this), I see 12 subjects(!). #Profile model class Profile < ActiveRecord::Base has_many :subjects accepts_nested_attributes_for :subjects end #Subject Model class Subject < ActiveRecord::Base belongs_to :profile end #Profile Controller (only showing deviations from normal RESTFUL setup) def new @profile = Profile.new 3.times do @profile.subjects.build end end #Here's 1 of three parts of the subject output of = debug @profile errors: !ruby/object:ActiveRecord::Errors base: *id004 errors: !map:ActiveSupport::OrderedHash {} subjects: - &id001 !ruby/object:Subject attributes: exam: Either name: "7" created_at: 2010-04-15 10:38:13 updated_at: 2010-04-15 10:38:13 level: Either id: "31" profile_id: "3" attributes_cache: {} # Note that 3 of these attributes are displayed despite me seeing 12 subjects on screen Other info in case it's relevant.

  • PHP and MS Access: Number of Records returned by SELECT query

    - by VarunGupta
    I am running following PHP code to interact with a MS Access database. $odbc_con = new COM("ADODB.Connection"); $constr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" . $db_path . ";"; $odbc_con -> open($constr); $rs_select = $odbc_con -> execute ("SELECT * FROM Main"); Using ($rs_select - RecordCount) gives -1 though the query is returning non-zero records. (a) What can be the reason? (b) Is there any way out? I have also tried using count($rs_select -> GetRows()). This satisfies the need but looks inefficient as it will involve copying of all the records into an array first.

  • Rails wiki highlight/strikethrough version differences between article versions

    - by mark
    Hi I'm wondering how to implement highlighting of changes to user edited articles on a wiki style rails project. Since articles may be fairly lengthy I'd ideally like strikethrough and highlighting, similar to github and wikipedia for example. Despite searching around the net I've not really come up with much, apart from instiki which is a complete wiki application. Thanks in advance for any advice.

  • Standalone jQuery or MooTools version of YooTools YOOcarousel

    - by R33BOOT
    I was wondering if anyone knows of a jQuery or MooTools script that will do the exact same thing as YOOcarousel (http://tools.yootheme.com/extensions/yoocarousel). I'm looking to emulate the 'List Styling' setup they have where on the left you have the tabbed navigation and on the right it fades in/out thru each of the tabbed items as they are clicked. Thanks, Ryan

  • R- delete rows in multiple columns by unique number

    - by Vincent Moriarty
    Given data like this C1<-c(3,-999.000,4,4,5) C2<-c(3,7,3,4,5) C3<-c(5,4,3,6,-999.000) DF<-data.frame(ID=c("A","B","C","D","E"),C1=C1,C2=C2,C3=C3) How do I go about removing the -999.000 data in all of the columns I know this works per column DF2<-DF[!(DF$C1==-999.000 | DF$C2==-999.000 | DF$C3==-999.000),] But I'd like to avoid referencing each column. I am thinking there is an easy way to reference all of the columns in a particular data frame aka: DF3<-DF[!(DF[,]==-999.000),] or DF3<-DF[!(DF[,(2:4)]==-999.000),] but obviously these do not work And out of curiosity, bonus points if you can me why I need that last comma before the ending square bracket as in: ==-999.000),]

  • Can't insert a number into a C++ custom streambuf/ostream

    - by 0xbe5077ed
    I have written a custom std::basic_streambuf and std::basic_ostream because I want an output stream that I can get a JNI string from in a manner similar to how you can call std::ostringstream::str(). These classes are quite simple. namespace myns { class jni_utf16_streambuf : public std::basic_streambuf<char16_t> { JNIEnv * d_env; std::vector<char16_t> d_buf; virtual int_type overflow(int_type); public: jni_utf16_streambuf(JNIEnv *); jstring jstr() const; }; typedef std::basic_ostream<char16_t, std::char_traits<char16_t>> utf16_ostream; class jni_utf16_ostream : public utf16_ostream { jni_utf16_streambuf d_buf; public: jni_utf16_ostream(JNIEnv *); jstring jstr() const; }; // ... } // namespace myns In addition, I have made four overloads of operator<<, all in the same namespace: namespace myns { // ... utf16_ostream& operator<<(utf16_ostream&, jstring) throw(std::bad_cast); utf16_ostream& operator<<(utf16_ostream&, const char *); utf16_ostream& operator<<(utf16_ostream&, const jni_utf16_string_region&); jni_utf16_ostream& operator<<(jni_utf16_ostream&, jstring); // ... } // namespace myns The implementation of jni_utf16_streambuf::overflow(int_type) is trivial. It just doubles the buffer width, puts the requested character, and sets the base, put, and end pointers correctly. It is tested and I am quite sure it works. The jni_utf16_ostream works fine inserting unicode characters. For example, this works fine and results in the stream containing "hello, world": myns::jni_utf16_ostream o(env); o << u"hello, wor" << u'l' << u'd'; My problem is as soon as I try to insert an integer value, the stream's bad bit gets set, for example: myns::jni_utf16_ostream o(env); if (o.badbit()) throw "bad bit before"; // does not throw int32_t x(5); o << x; if (o.badbit()) throw "bad bit after"; // throws :( I don't understand why this is happening! Is there some other method on std::basic_streambuf I need to be implementing????

  • Python calling class methods with the wrong number of parameters

    - by Hussain
    I'm just beginning to learn python. I wrote an example script to test OOP in python, but something very odd has happened. When I call a class method, Python is calling the function with one more parameter than given. Here is the code: 1. class Bar: 2. num1,num2 = 0,0 3. def __init__(num1,num2): 4. num1,num2 = num1,num2 5. def foo(): 6. if num1 num2: 7. print num1,'is greater than ',num2,'!' 8. elif num1 is num2: 9. print num1,' is equal to ',num2,'!' 10. else: 11. print num1,' is less than ',num2,'!' 12. a,b,t = 42,84,bar(a,b) 13. t.foo 14. 15. t.num1 = t.num1^t.num2 16. t.num2 = t.num2^t.num1 17. t.num1 = t.num1^t.num2 18. 19. t.foo 20. And the error message I get: python test.py Traceback (most recent call last): File "test.py", line 12, in a,b,t = 42,84,bar(a,b) NameError: name 'bar' is not defined Can anyone help? Thanks in advance

  • Internet Explorer not incrementing number for non-sibling <li> elements

    - by biagidp
    I've got some html that looks like this: <ol> <div> <li>one</li> </div> <div> <li>two</li> </div> <div> <li>three</li> </div> </ol> Which looks like this in Chrome/Firefox: 1. one 2. two 3. three But looks like this in IE: 1. one 1. two 1. three If I change the code so that the li element is the parent of the div element instead of the other way around (so that all the li elements are siblings) IE renders it correctly. Anyone know what causes this or if this is the intended working behavior of IE? Furthermore is one way technically more correct than the other? <div><li></li></div> VS. <li><div></div></li> Thanks, David
