  • Internet explorer only executing function inside jQuery ajax success response once even though there

    - by user249950
    Hi, I have a function that uses jQuery.load() to call in 3 snippets of forms from different pages and then on the success text status it tries to load a colour picker: $(document).ready(function() { function ajax_form(putloadingboxhere, putsnippethere, snippeturl) { $(putsnippethere).load(snippeturl, function (responseText, textStatus, XMLHttpRequest, ) { if (textStatus == "success") { alert('One') $("input.pickcolor").ColorPicker({ onShow: function (colpkr) { $(colpkr).fadeIn(500); return false; }, onSubmit: function(hsb, hex, rgb, el) { $(el).val(hex); $(el).ColorPickerHide(); $(el).siblings('.colorpreview').css('background-color', '#' + hex); }, onBeforeShow: function () { $(this).ColorPickerSetColor(this.value); } }) .bind('keyup', function(){ $(this).ColorPickerSetColor(this.value); }); alert('Two') } if (textStatus == "error") { // Show error message } }); } ajax_form('tab_box', '#formone', 'snippet_one.htm #snippet'); ajax_form('tab_box', '#formtwo', 'snippet_two_copy.htm #snippet'); ajax_form('tab_box', '#formthree', 'snippet_three.htm #snippet'); }); It works fine in Firefox and Safari but (surprise, surprise) IE has a problem with it. I have added an alert to see what is going on before and after one of the functions. FF & Safari & IE8: Alert 'one' and Alert 'two' appear three times as expected and colour picker appears. IE6 & 7: Alert 'one' shows three times and colour picker does not appear. Any help would be great! Cheers. EDIT The line IE is referring to when it throws this error: 'Error: Object doesn't support this property or method.' is: $('input.pickcolor').ColorPicker Anyone got any insights? Thanks

  • Android - need UI help/advice

    - by Donal Rafferty
    I have been working on Android for the past couple of months getting to know how various components work. One area I am completely lacking in knowledge is any sort of User Interface or graphical interface creation. As an excercise I have been asked to break down the HTC call screen into what components it contains and rebuild as close as possible. Here is a picture of the HTC call screen: From my understanding the above UI has a custom title bar where "Meteor" and the call time appears. Then the main image in the middle block along with a text view showing the called party, in this case "Voice Mail" and the number. The bottom is then a custom view maybe with three custom buttons used within it. Would I be correct in my above assumptions? So the parts I should look into start programming are a custom title bar and a custom view with three custom buttons to place at the bottom? What layout would be reccomended? I hope this question is seen as relative to Stack Overflow, if it is not then I will delete it. Thanks in advance

  • How important is PhD research topic to getting a job?

    - by thornate
    EDIT: This has been closed and I realise that I may not have been specific enough with the original title. I ask two questions here: The general one (Does a PhD help get a job?) which has been asked elsewhere, and the specific one (Is it possible to get work outside of the specific research field?). Assume I've already decided going to do the phd. I'm just stressing about the research topic. Well, I'm one year out of university (Mechatronics engineering and Software Eng double bachelors), worked for a few months then got retrenched (yay economy!). It's looking less and less likely that I'll get a job worth having with the job market as it is, so I'm thinking about going back to uni to do a PhD. I figure that by the time I'm done, the job market will have improved and hopefully I'll have something on my resume that is more attractive than spending three years doing customer support for accounting software. So, my question is to people who've done PhD's. Would you say that they were worth the effort? How important is the research topic to future job-seeking success? The idea I have is a computer-sciencey/neural-networks/data-mining thing which I think is very interesting, but not a field I want to be in forever. My potential supervisor claims that employers don't care so much about the topic of the research but rather the peripheral skills that are developed through a PhD; time managment, self-restraint, planning and whatnot. How does this mesh with people's real world experience? I'd appreciate any advice before signing my life on the line for the next three years. See also: Should developers go to grad school? Best reason not to hire a PhD? How to find an entry-level job after you already have a graduate degree?

  • ntpd on Fedora Core 6 with high negative time rest values

    - by Mark White
    The basic problem is we have a FC6 server instance running on a virtual machine, and the system time seems to have been slowly varying until it is now causing a problem. The server runs 24/7 and has been up for 155 days. It has been changed to show GMT, and reports the time as (example) 00:15:15 GMT whereas the actual time is 00:00:00 GMT. This is an offset of 915 seconds. selinux has been changed to 'setenforce 0' for testing and I am running as root. I stop the ntpd service and change the time in System|Administration|Date & Time. The time still shows the same with 'date' in bash. There are no error logs. I change the date with 'date --set' in bash. The response confirms the changed date. I run 'date' and the incorrect date is shown. There are no error logs. I start the ntpd service and /var/log/messages shows success with 'time reset -915.720139s'. The date remains unchanged. ntpq -p shows three three time servers all have offsets of around -915 seconds. I stop ntpd service and try 'ntpd -gqx' and get the same result as above - success, but a large negative time reset. I've tried varying combinations of the above, and a few more settings in System|Administration|Date & Time - no change. I just need to reset the system time to GMT. No offset. But I can't wait for ntpd to slew the time over the next few weeks. Any advice is welcome, cheers! Sure this shouldn't be this difficult... Mark...

  • Why can't I use WCF DataContract and ISerializable on the same class?

    - by Dave
    Hi all, I have a class that I need to be able to serialize to a SQLServer session variable and be available over a WCF Service. I have declared it as follows namespace MyNM { [Serializable] [DataContract(Name = "Foo", Namespace = "http://www.mydomain.co.uk")] public class Foo : IEntity, ISafeCopy<Foo> { [DataMember(Order = 0)] public virtual Guid Id { get; set; } [DataMember(Order = 1)] public virtual string a { get; set; } DataMember(Order = 2)] public virtual Bar c { get; set; } /* ISafeCopy implementation */ } [Serializable] [DataContract(Name = "Bar ", Namespace = "http://www.mydomain.co.uk")] public class Bar : IEntity, ISafeCopy<Bar> { #region Implementation of IEntity DataMember(Order = 0)] public virtual Guid Id { get; set; } [DataMember(Order = 1)] public virtual Baz y { get; set; } #endregion /* ISafeCopy implementation*/ } [Serializable] [DataContract] public enum Baz { [EnumMember(Value = "one")] one, [EnumMember(Value = "two")] two, [EnumMember(Value = "three")] three } But when I try and call this service, I get the following error in the trace log. "System.Runtime.Serialization.InvalidDataContractException: Type 'BarProxybcb100e8617f40ceaa832fe4bb94533c' cannot be ISerializable and have DataContractAttribute attribute." If I take out the Serializable attribute, the WCF service works, but when the object can't be serialized to session. If I remove the DataContract attribute from class Bar, the WCF service fails saying Type 'BarProxy3bb05a31167f4ba492909ec941a54533' with data contract name 'BarProxy3bb05a31167f4ba492909ec941a54533:http://schemas.datacontract.org/2004/07/' is not expected. Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer I've tried adding a KnownType attribute to the foo class [KnownType(typeof(Bar))] But I still get the same error. Can anyone help me out with this? Many thanks Dave

  • jquery creating stacked bar chart with flot?

    - by KittyYoung
    I'm using jquery flot and I'm trying to create a stacked bar chart, but I'm having some syntax issues... I'll post my code at the end of this, but I'm quite certain it's wrong. I do get a stacked bar chart, but there's only three columns... Basically, here is the data that I'm working with and what I want to accomplish... The first group (Focus Group 1) on each line is the bottom bar of the stacked bar, the second group (Focus Group 2) is the second, and the third group (Focus Group 3) is the top group. The "Responses" are what I want to use on the x-axis, the first number in each set is x, and the second number is y. Response1, [0, 0], [0,0], [0,9] Response2, [1, 5], [1,5], [1,11] Response3, [2, 2], [2,0], [2,8] Response4, [3, 1], [3,2], [3,6] Response5, [4, 0], [4,0], [4,7] I should also mention, that I'm not sure if a stacked chart is the best way to go... Admittedly, I'm not a very visual person, and generally find charts annoying... If there's a better way to present this data, then I am so totally open to suggestions... Essentially... I have a series of questions. Each of these questions were presented to three focus groups. Members of the focus groups selected a response. I'm trying to present the count per response, per focus group, for each question. I thought that a stacked chart would be the best way to go, but again, I'm open to other ways of doing this. The only thing is, I definitely need a visual representation of the data....

  • should this database table be normalized?

    - by oo
    i have taken over a database that stores fitness information and we were having a debate about a certain table and whether it should stay as one table or get broken up into three tables. Today, there is one table called: workouts that has the following fields id, exercise_id, reps, weight, date, person_id So if i did 2 sets of 3 different exercises on one day, i would have 6 records in that table for that day. for example: id, exercise_id, reps, weight, date, person_id 1, 1, 10, 100, 1/1/2010, 10 2, 1, 10, 100, 1/1/2010, 10 3, 1, 10, 100, 1/1/2010, 10 4, 2, 10, 100, 1/1/2010, 10 5, 2, 10, 100, 1/1/2010, 10 6, 2, 10, 100, 1/1/2010, 10 So the question is, given that there is some redundant data (date, personid, exercise_id) in multiple records, should this be normalized to three tables WorkoutSummary: - id - date - person_id WorkoutExercise: - id - workout_id (foreign key into WorkoutSummary) - exercise_id WorkoutSets: - id - workout_exercise_id (foreign key into WorkoutExercise) - reps - weight I would guess the downside is that the queries would be slower after this refactoring as now we would need to join 3 tables to do the same query that had no joins before. The benefit of the refactoring allows up in the future to add new fields at the workout summary level or the exercise level with out adding in more duplication. any feedback on this debate?

  • CSS background image being downloaded more than once

    - by Nick Clarke
    I noticed in my current project that Firefox (3.5.4) downloads the background image (set in CSS) for my divs more than once. I've checked with both firebug and wireshark and it really does appear that it does not wait for the first request to finish and then simply use the cached version. Wireshark also confirms that Chrome and IE8 do as expected and only request the image once. Any ideas what might be causing this? Here is a small test: Sample Page or <html> <head> <style> #one { height: 300px; width:100%; background: #FFF url('random.jpg'); } #two { height: 300px; width:100%; background: #FFF url('random.jpg'); } #three { height: 300px; width:100%; background: #FFF url('random.jpg'); } </style> </head> <body> <div id="one"></div> <div id="two"></div> <div id="three"></div> </body> EDIT I opened up a bug request as I could not find one already on bugzilla, but it turns out to be an old bug with 3.5. https://bugzilla.mozilla.org/show_bug.cgi?id=497665

  • Help with C puzzle

    - by Javier Badia
    I found a site with some complicated C puzzles. Right now I'm dealing with this: The following is a piece of C code, whose intention was to print a minus sign 20 times. But you can notice that, it doesn't work. #include <stdio.h> int main() { int i; int n = 20; for( i = 0; i < n; i-- ) printf("-"); return 0; } Well fixing the above code is straight-forward. To make the problem interesting, you have to fix the above code, by changing exactly one character. There are three known solutions. See if you can get all those three. I cannot figure out how to solve. I know that it can be fixed by changing -- to ++, but I can't figure out what single character to change to make it work.

  • How to dispatch a new property value in an object to the same property of two other objects

    - by WPFadvocate
    In WPF, I've three objects exposing the same DependencyProperty (let's say it's an integer). I want all three property values to remain synchronized, i.e. that whenever the int value changes in an object, this value is propagated to the two other objects. I think of multibinding to do the job, but I don't know how to detect which object changed, thus which value should be used and propagated to the other objects. Edited: here is my tentative code for multibinding, with the false hope that it would work without additional code: // create the multibinding MultiBinding mb = new MultiBinding() { Mode = BindingMode.TwoWay, UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged }; // create individual bindings to associate object_2 and object_3 to object_1 Binding b2 = new Binding() { Source = object_2, Path = new PropertyPath("X") }; Binding b3 = new Binding() { Source = object_3, Path = new PropertyPath("X") }; // add individual bindings to multibinding mb.Bindings.Add(b2); mb.Bindings.Add(b3); // bind object_2 and _3 to object_1 BindingOperations.SetBinding(object_1, TypeObject_1.XProperty, mb); But actually, there is a runtime error, saying the binding set by the last instruction is lacking a converter. But again I don't know how to write this converter (there is nothing to convert (as this is the case in the related MS sample of code linking 3 rgb properties to a color property), only to forward the value of the property changed to the two other properties). I understand I could solve the problem by creating an X_Changed event in the 3 types and then have each object registering to the two other objects event. I don't like this "manual" way and would prefer to bind the 3 properties together.

  • Learning Objective-C: Need advice on populating NSMutableDictionary

    - by Zigrivers
    I am teaching myself Objective-C utilizing a number of resources, one of which is the Stanford iPhone Dev class available via iTunes U (past 2010 class). One of the home work assignments asked that I populate a mutable dictionary with a predefined list of keys and values (URLs). I was able to put the code together, but as I look at it, I keep thinking there is probably a much better way for me to approach what I'm trying to do: Populate a NSMutableDictionary with the predefined keys and values Enumerate through the keys of the dictionary and check each key to see if it starts with "Stanford" If it meets the criteria, log both the key and the value I would really appreciate any feedback on how I might improve on what I've put together. I'm the very definition of a beginner, but I'm really enjoying the challenge of learning Objective-C. void bookmarkDictionary () { NSMutableDictionary* bookmarks = [NSMutableDictionary dictionary]; NSString* one = @"Stanford University", *two = @"Apple", *three = @"CS193P", *four = @"Stanford on iTunes U", *five = @"Stanford Mall"; NSString* urlOne = @"http://www.stanford.edu", *urlTwo = @"http://www.apple.com", *urlThree = @"http://cs193p.stanford.edu", *urlFour = @"http://itunes.stanford.edu", *urlFive = @"http://stanfordshop.com"; NSURL* oneURL = [NSURL URLWithString:urlOne]; NSURL* twoURL = [NSURL URLWithString:urlTwo]; NSURL* threeURL = [NSURL URLWithString:urlThree]; NSURL* fourURL = [NSURL URLWithString:urlFour]; NSURL* fiveURL = [NSURL URLWithString:urlFive]; [bookmarks setObject:oneURL forKey:one]; [bookmarks setObject:twoURL forKey:two]; [bookmarks setObject:threeURL forKey:three]; [bookmarks setObject:fourURL forKey:four]; [bookmarks setObject:fiveURL forKey:five]; NSString* akey; NSString* testString = @"Stanford"; for (akey in bookmarks) { if ([akey hasPrefix:testString]) { NSLog(@"Key: %@ URL: %@", akey, [bookmarks objectForKey:akey]); } } } Thanks for your help!

  • CIE XYZ colorspace: is it RGBA or XYZA?

    - by Tronic
    I plan to write a painting program based on linear combinations of xy plane points (0,1), (1,0 ) and (0,0). Such system works identically to RGB, except that the primaries are not within the gamut but at the corners of a triangle that encloses the entire gamut, therefore allowing for all colors to be reproduced. I have seen the three points being referred to as X, Y and Z (upper case) somewhere, but I cannot find the page anymore. My pixel format stores the intensity of each of those three components the same way as RGB does, together with alpha value. This allows using pretty much any image manipulation operation designed for RGBA without modifying the code. What is my format called? Is it XYZA, RGBA or something else? Google doesn't seem to know of XYZA and RGBA will get confused with sRGB + alpha (which I also need to use in the same program). Notice that the primaries X, Y and Z and their intensities have little to do with the x, y and z coordinates (lower case) that are more commonly used.

  • Monotouch.dialog and story board apps?

    - by Robin Diederen
    I'm trying to use mt.d; I've "drawn" an app using the storyboard feature of Xcode. My app consists of a tabbar which displays one of three viewcontrollers. Two out of three are simple viewcontrollers (single screens) and one is a splitviewcontroller. The splitview is tricky; using the stock xcode components I've drawn a master / table and a detail view. The table works as expected, but now I want to use mt.d to fill the detailview (later I need it to depend on the selection of the master, but not for now). I've subclassed the splitviewcontroller; in the viewdidload event I've created a mt.d dialogviewcontroller. Now I'm trying to push the dialogviewcontroller to the detailview, using the splitviewcontroller.viewcontrollers array. Doesn't seem to work; when running the app it still some an empty screen for the detail view (as drawn in xcode). Any clues for doing what I want? Thanx!

  • Starting a new business with former colleagues, advice needed

    - by Sparafusile
    I was recently contacted by a former boss of mine who is thinking of starting a new business. The business will be online only it will by my job to design, build, and maintain the software going into it. I will also have to maintain the server it's running on, being the only technical person on the team. I will be one of four members of the business, the other three being the actual business know-hows and salesmen. The other three are shouldering the cost of getting the business going (incorporation, attorney fees, etc) and we will be splitting the cost of the server. I have no business knowledge at all, and don't want any part of it, I am only interested in the technical aspects. Now that we are finalizing our plans, determining roles, and getting ready to start actual work, we have come to the point where we have to determine what percentage stake each of us has. Since I have never done anything like this before, or met anyone that has, I don't know what I should expect. Can anyone give me some pointers on what to ask for in this deal?

  • Application Architect vs. Systems Architect vs. Enterprise Architect?

    - by iaman00b
    So many buzzwords. Not sure if I need to start playing BS Bingo or not. And I'm not trying to be cynical. But I've heard many people with these various titles. There never seems to be a clear delineation between the three. Or there's a lot of domain crossover between the three. Actually, another I've seen while looking around here on Stackoverflow has been "Solutions Architect" as well. But that one doesn't seem to be so prevalent in other places. There are questions here and there with vague answers. But I'd like definative answers to this. Please assume I'm still relatively new to software stuff and that I'm trying to map out a career path. Oh, and please be gentle folks; this most definitely is not a duplicate question. Neither is it an aggregate. So kindly leave it alone. Xp

  • Getting the size of the window WITHOUT title/notification bars

    - by Anidamo
    Hi there, I've been playing around with Android development and one of the things I'd like to be able to do is dynamically create a background image for my windows, similar to the one below. This is from my BlackBerry app. It consists of three separate parts, the bottom right logo, the top left watermark, and the bottom right name. It works independent of screen size because the BlackBerry app just gets all three parts and generates an appropriately sized bitmap using the screen width and height. Since Android has quite a bit more screen resolution possibilities I need to be able to generate backgrounds on the fly like this. However, I have not found any way to get the height/width of the window in Android. I can get the screen resolution, but that includes the application title bar and the notification bar, which is unacceptable. I'd like to know how to get the size of my window, or screen resolution minus the title and notification bars. I think this might be possible using the dimensions of my layout managers but I cannot get the height/width of them in the onCreate method so I'm at a little bit of a loss. Thanks.

  • Functional way to get a matrix from text

    - by Elazar Leibovich
    I'm trying to solve some Google Code Jam problems, where an input matrix is typically given in this form: 2 3 #matrix dimensions 1 2 3 4 5 6 7 8 9 # all 3 elements in the first row 2 3 4 5 6 7 8 9 0 # each element is composed of three integers where each element of the matrix is composed of, say, three integers. So this example should be converted to #!scala Array( Array(A(1,2,3),A(4,5,6),A(7,8,9), Array(A(2,3,4),A(5,6,7),A(8,9,0), ) An imperative solution would be of the form #!python input = """2 3 1 2 3 4 5 6 7 8 9 2 3 4 5 6 7 8 9 0 """ lines = input.split('\n') print lines[0] m,n = (int(x) for x in lines[0].split()) array = [] row = [] A = [] for line in lines[1:]: for elt in line.split(): A.append(elt) if len(A)== 3: row.append(A) A = [] array.append(row) row = [] from pprint import pprint pprint(array) A functional solution I've thought of is #!scala def splitList[A](l:List[A],i:Int):List[List[A]] = { if (l.isEmpty) return List[List[A]]() val (head,tail) = l.splitAt(i) return head :: splitList(tail,i) } def readMatrix(src:Iterator[String]):Array[Array[TrafficLight]] = { val Array(x,y) = src.next.split(" +").map(_.trim.toInt) val mat = src.take(x).toList.map(_.split(" "). map(_.trim.toInt)). map(a => splitList(a.toList,3). map(b => TrafficLight(b(0),b(1),b(2)) ).toArray ).toArray return mat } But I really feel it's the wrong way to go because: I'm using the functional List structure for each line, and then convert it to an array. The whole code seems much less efficeint I find it longer less elegant and much less readable than the python solution. It is harder to which of the map functions operates on what, as they all use the same semantics. What is the right functional way to do that?

  • How to handle media kept on a separate server (PHP)

    - by Sandman
    So, I have three server, and the idea was to keep all media (images, files, movies) on a media server. I never got around to do it but I think I probably should. So these are the three servers: WWW server DB server Media server Visitors obviously connect to the WWW server and currently image resizing and cache:ing is done on the WWW servers as the original files are kept there. So the idea for me is for image functions I have, that does all the image compositioning, resizing and cahceing would just pie the command over to the media server that would return ther path to the finnished file. What I don't know is how to handle functions such as file_exists() and figuring out image dimensions when needed before even any image management comes into play. Do I pipe all these commands to the other server, via HTTP? I was thinking along the ways of doing it this way: function image(##ARGS##){ if ($GLOBALS["media_host"] != "localhost"){ list ($src, $width, height) = file('http://$GLOBALS[media_host]/imgfunc.php?args=##ARGS##'); return "<img src='$src' height and width >"; } .... do other stuff here } Am I approaching this the wrong way? Is there a better way to do this?

  • Doing large updates against indexed view

    - by user217136
    We have an indexed view that runs across three large tables. Two of these tables (A & B) are constantly getting updated with user transactions and the other table (C) contains data product info that is needs to be updated once a week. This product table contains over 6 million records. We need this view across these three tables for our core business process and unfortunately we cannot change this aspect. We even had a sql server MVP come in to help test under load to make sure we have the most efficient configuration. There is one column in the product table that gets utilized in the view and has to be updated each week. The problem we are now encountering is that as volume is increasing on our transactions against tables A & B, the update to Table C is causing deadlocks. I have tried several different methods to no avail: 1) I was hoping that we could change the view so that table C could be a dirty read "WITH (NOLOCK)" but apparently that functionality is not available with indexes views. 2) I thought about updating a new column in Table C and then just renaming it when the process is done but you cannot do that due to the dependency in the view. 3) I also entertained the idea of writing this value to a temporary product table, and then running an ALTER statement against the view to have it point to my new table. however when i did that the indexes on my view were dropped and it took quite a bit of time to recreate them. 4) we tried to do the weekly update in small chunks (as small as 100 records at a time) but we still run into dead locks. questions: a) we are using sql server 2005. Does sql server 2008 have a new functionality with their indexed views that would help us? Is there now a way to do dirty reads w/ an indexed view? b) a better approach to altering an existing view to point to a new table? thanks!

Given text : "Twenty-three" The main trick the having some html tags tags need to keep that tag with this content only the words from 10before - 10after content is bellow : <div id="hpFeatureBoxInt"><h2><span class="dy">Top News Story</span></h2><h3><a href="/go/homepage/i/int/news/world/1/-/news/1/hi/world/europe/8592190.stm">Suicide bombings hit Moscow Metro</a></h3><p>Past suicide bombings in Moscow have been blamed on Islamist rebels At least 35 people have been killed after two female suicide bombers blew themselves up on Moscow Metro trains in the morning rush hour, officials say.<img height="150" width="201" alt="Emergency services carry a body from a Metro station in Moscow (29 March 2010)" src="http://wwwimg.bbc.co.uk/feedengine/homepage/images/_47550689_moscowap203_201x150.jpg">Twenty-three died in the first blast at 0756 (0356 GMT) as a<a href="#"> train stood </a>at the central Lubyanka station, beneath the offices of the FSB intelligence agency.About 40 minutes later, a second explosion ripped through a train at Park Kultury, leaving another 12 dead.No-one has said they carried out the worst attack in the capital since 2004. </p><p id="fbilisten"><a href="/go/homepage/i/int/news/heading/-/news/">More from BBC News</a></p></div> Thank you

  • Call by Reference Function in C

    - by Chad
    Hello everyone, I would just like a push in the right direction here with my homework assignment. Here is the question: (1) Write a C function called input which returns void, this function prompts the user for input of two integers followed by a double precision value. This function reads these values from the keyboard and finds the product of the two integers entered. The function uses call by reference to communicate the values of the three values read and the product calculated back to the main program. The main program then prints the three values read and the product calculated. Provide test results for the input: 3 5 23.5. Do not use arrays or global variables in your program. And here is my code: #include <stdio.h> #include <stdlib.h> void input(int *day, int *month, double *k, double *pro); int main(void){ int i,j; double k, pro; input(&i, &j, &k, &pro); printf("%f\n", pro); return 0; } void input(int *i, int *j, double *k, double *pro){ int x,y; double z; double product; scanf("%d", &x); scanf("%d", &y); scanf("%f", &z); *pro += (x * y * z); } I can't figure out how to reference the variables with pointers really, it is just not working out for me. Any help would be great!

  • BitBlting multiple images to buffer

    - by Anonymous
    So I've made a class which draws a transparant image to a buffer. the buffer is a HDC which has been used blackness on. What I am trying to do is draw three images to this buffer. Which means I am using this function three times. After that's done, I output it to the screen (using SRCCOPYing the buffer). But what I get to see is just the third image and blackness. void draw_buffer(HDC buffer, int draw_x, int draw_y) { BitBlt(this-main, draw_x, draw_y, this-img_width, this-img_height, this-image, this-mask_x, this-mask_y, SRCAND); BitBlt(this-main, draw_x, draw_y, this-img_width, this-img_height, this-image, this-img_x, this-img_y, SRCPAINT); BitBlt(buffer, 0, 0, 800, 600, this-main, 0, 0, SRCCOPY); } At initiation, this-main becomes this: this->main = CreateCompatibleDC(GetDC(0)); this->bitmap = CreateCompatibleBitmap(GetDC(0),800,600); SelectObject(this->main, this->bitmap); What is wrong with my code?

  • Django: Named URLs / Same Template, Different Named URL

    - by TheLizardKing
    I have a webapp that lists all of my artists, albums and songs when the appropriate link is clicked. I make extensive use of generic views (object_list/detail) and named urls but I am coming across an annoyance. I have three templates that pretty much output the exact same html that look just like this: {% extends "base.html" %} {% block content %} <div id="content"> <ul id="starts-with"> {% for starts_with in starts_with_list %} <li><a href="{% url song_list_x starts_with %}">{{ starts_with|upper }}</a></li> {% endfor %} </ul> <ul> {% for song in songs_list %} <li>{{ song.title }}</li> {% endfor %} </ul> </div> {% endblock content %} My artist and album template look pretty much the same and I'd like to combine the three template's into one. The fact that my variables start with song can easily be changed to the default obj. It's my <ul id="starts-with"> named url I don't know how to correct. Obviously I want it to link to a specific album/artist/song using the named urls in my urls.py but I don't know how to make it context aware. Any suggestions? urlpatterns = patterns('tlkmusic.apps.tlkmusic_base.views', # (r'^$', index), url(r'^artists/$', artist_list, name='artist_list'), url(r'^artists/(?P<starts_with>\w)/$', artist_list, name='artist_list_x'), url(r'^artist/(?P<artist_id>\d+)/$', artist_detail, name='artist_detail'), url(r'^albums/$', album_list, name='album_list'), url(r'^albums/(?P<starts_with>\w)/$', album_list, name='album_list_x'), url(r'^songs/$', song_list, name='song_list'), url(r'^songs/(?P<starts_with>\w)/$', song_list, name='song_list_x'), )

  • Duplicate Items Using Join in NHibernate Map

    - by Colin Bowern
    I am trying to retrieve the individual detail rows without having to create an object for the parent. I have a map which joins a parent table with the detail to achieve this: Table("UdfTemplate"); Id(x => x.Id, "Template_Id"); Map(x => x.FieldCode, "Field_Code"); Map(x => x.ClientId, "Client_Id"); Join("UdfFields", join => { join.KeyColumn("Template_Id"); join.Map(x => x.Name, "COLUMN_NAME"); join.Map(x => x.Label, "DISPLAY_NAME"); join.Map(x => x.IsRequired, "MANDATORY_FLAG") .CustomType<YesNoType>(); join.Map(x => x.MaxLength, "DATA_LENGTH"); join.Map(x => x.Scale, "DATA_SCALE"); join.Map(x => x.Precision, "DATA_PRECISION"); join.Map(x => x.MinValue, "MIN_VALUE"); join.Map(x => x.MaxValue, "MAX_VALUE"); }); When I run the query in NH using: Session.CreateCriteria(typeof(UserDefinedField)) .Add(Restrictions.Eq("FieldCode", code)).List<UserDefinedField>(); I get back the first row three times as opposed to the three individual rows it should return. Looking at the SQL trace in NH Profiler the query appears to be correct. The problem feels like it is in the mapping but I am unsure how to troubleshoot that process. I am about to turn on logging to see what I can find but I thought I would post here in case someone with experience mapping joins knows where I am going wrong.
