• Secure to store an ID in an ASP.NET control ID?

  - by Curtis White

  I'm auto-generating a form in my ASP.NET page. This is already tested and working. I want to know if: If there are any security problems with storing the database ID as part of my controls ID? I can see think of 2 issues: the id will be visible in page source (not really important in this case), and the possibility someone could change the name of the control somehow? This second possibility is more serious. Is this a potential problem and how to void it? If there would be a better preferred way to associate a unique data with any type of control? Is it possible to store a custom item in the viewstate for the control?

• python len calculation

  - by n00bz0r

  I'm currently trying to build a RDP client in python and I came across the following issue with a len check; From: http://msdn.microsoft.com/en-us/library/cc240836%28v=prot.10%29.aspx "81 2a - ConnectData::connectPDU length = 298 bytes Since the most significant bit of the first byte (0x81) is set to 1 and the following bit is set to 0, the length is given by the low six bits of the first byte and the second byte. Hence, the value is 0x12a, which is 298 bytes." This sounds weird. For normal len checks, I'm simply using : struct.pack("h",len(str(PacketLen))) but in this case, I really don't see how I can calculate the len as described above. Any help on this would be greatly appreciated !

• Optional URL fragment in Codeigniter?

  - by DA

  This is maybe a simple syntax question or possibly a best-practices question in terms of codeigniter. I should start by saying I'm not a PHP or Codeigniter person so trying to get up to speed on helping on a project. I've found the CI documentation fairly good. The one question I can't find an answer to is how to make part of a URL optional. An example the CI documentation uses is this: example.com/index.php/products/shoes/sandals/123 and then the function used to parse the URI: function shoes($sandals, $id) For my example, I'd like to be able to modify the URL as such: example.com/index.php/products/shoes/all So, if no ID is passed, it's just ignored. Can that be done? Should that be done? A second question unrelated to my problem but pertaining to the example above, why would the variable $sandals be used as in the example, the value is 'sandals'? Shouldn't that variable be something like $shoetype?

• C++ arrays select square number and make new vector

  - by John Smith

  I have to see which of the following from a vector is a square number then make another vector with only the square numbers For example: (4,15,6,25,7,81) the second will be (4,25,81) 4,25,81 because 2x2=4 5x5=25 and 9x9=81 I started like this: { int A[100],n,r,i; cout<<"Number of elements="; cin>>n; for(i=1;i<=n;i++) { cout<<"A["<<i<<"]="; cin>>A[i]; } for(i=1;i<=n;i++) { r=sqrt(A[i]); if(r*r==A[i]) } return 0; } but I am not really sure how to continue

• Assign the results of a stored procedure into a variable in another stored procedure

  - by RHPT

  The title of this question is a bit misleading, but I couldn't summarize this very well. I have two stored procedures. The first stored procedure (s_proc1) calls a second stored procedure (s_proc2). I want to assign the value returned from s_proc2 to a variable in s_proc1. Currently, I'm calling s_proc2 (inside s_proc1) in this manner: EXEC s_proc2 @SiteID, @count = @PagingCount OUTPUT s_proc2 contains a dynamic query statement (for reasons I will not outline here). CREATE dbo.s_proc2 ( @siteID int, @count int OUTPUT ) AS DECLARE @sSQL nvarchar(100) DECLARE @xCount int SELECT @sSQL = 'SELECT COUNT(ID) FROM Authors' EXEC sp_ExecuteSQL @sSQL, N'@xCount int output', @xCount output SET @count = @xCount RETURN @count Will this result in @PagingCount having the value of @count? I ask because the result I am getting from s_proc1 is wonky. In fact, what I do get is two results. The first being @count, then the result of s_proc1 (which is incorrect). So, it makes me wonder if @PagingCount isn't being set properly. Thank you.

• How do I attach an event handler to the document or window in GWT?

  - by Raph Levien

  In a GWT app centered around a canvas, I'm having trouble keeping focus directed in the right place - particularly for keyboard shortcuts. For now, I've wrapped the canvas in a FocusPanel, but that causes the canvas to not respond to the RequiresResize protocol, because FocusPanel does not plumb that. A second (related, I think) problem is that the FocusPanel is not getting Ctrl-A keypress events at all (tested on Mac Chrome). I can get Ctrl-Z and other keys (such as arrows) just fine. In a pure JavaScript world, I think the best answer to this would be to attach mouse and key handlers to the document or window object (I'm not positive which is better). However, I don't see an obvious way to do this in GWT - in particular, the Document and Window classes lack methods for attaching these kind of event handlers? Anyone know how to do it, or, perhaps, to solve the more general problem of keeping focus on an appropriate widget able to handle keyboard shortcuts?

• Errors in UILabel

  - by Todd Davies

  I'm trying to use the FXlabel when following this (Adding a gradient label section) tutorial. This is some of the code inside my viewDidLoad method: self.logoLabel = [[FXLabel alloc] initWithFrame:CGRectMake(14, 11, 280, 87)]; [logoLabel setFont:[UIFont boldSystemFontOfSize:45]]; [logoLabel setTextColor:[UIColor whiteColor]]; [logoLabel setShadowColor:[UIColor blackColor]]; [logoLabel setShadowOffset:CGSizeMake(0, 2)]; [logoLabel setTextAlignment:UITextAlignmentCenter]; [logoLabel setBackgroundColor:[UIColor clearColor]]; [logoLabel setText:@"Attorney Biz"]; [logoLabel setGradientStartColor:[UIColor colorWithRed:163.0/255 green:203.0/255 blue:222.0/255 alpha:1.0]]; [logoLabel setGradientEndColor:[UIColor whiteColor]]; Unfortnuately, I get an error "No visible @interface for 'UILabel' declares the selector 'setGradientStartColor'" at the second-to-last line and "No visible @interface for 'UILabel' declares the selector 'setGradientEndColor'" Can somebody explain how to remove these errors?

• Rails + RSpec problem

  - by FancyDancy

  I have just installed Rspec and Rspec-rails. When i try to run the test, it says: rake aborted! Command /opt/local/bin/ruby -I"lib" "/opt/local/lib/ruby/gems/1.8/gems/rspec-1.3.0/bin/spec" "spec/controllers/free_controller_spec.rb" --options "/Volumes/Trash/dev/app/trunk/spec/spec.opts" failed Full log here: http://pastie.org/939211 However, my second "test" application with sqlite works with it. I think the problem is in my DB. My ruby version is 1.8.7, i use mysql as database. My files: specs/spec_helper.rb config/environment.rb config/environments/test.rb List of my gems My test is just: require 'spec_helper' describe FreeController do it "should respond with success" do get 'index' response.should be_success end end I really can't understand the error, so i don't know how to fix it.. Additional question: should i use a fixtures and ActiveRecord, if i going to use Machinist for creating test data? What should i do to disable them?

• How does compiling circular dependencies work?

  - by Fabio F.

  I've made the example in Java but I think (not tested) that it works in other (all?) languages. You have 2 files. First, M.java: public class MType { XType x; MType() {x = null;} } Second, another file (in the same directory), XType.java: public class XType { MType m; public XType(MType m) {this.m = m;} } Ok it's bad programming, but if you run javac XType it compiles: compiles even MType because XType needs it. But ... MType needs XType ... how does that work? How does the compiler know what is happening? Probably this is a stupid question, but I would like to know how the compiler (javac or any other compilers you know) manages that situation, not how to avoid it. I'm asking because i'm writing a precompiler and I would like to manage that situation.

• perl: added hash entry in a subroutine is lost

• STL deque accessing by index is O(1)?

  - by jasonline

  I've read that accessing elements by position index can be done in constant time in a STL deque. As far as I know, elements in a deque may be stored in several non-contiguous locations, eliminating safe access through pointer arithmetic. For example: abc-defghi-jkl-mnop The elements of the deque above consists of a single character. The set of characters in one group indicate it is allocated in contiguous memory (e.g. abc is in a single block of memory, defhi is located in another block of memory, etc.). Can anyone explain how accessing by position index can be done in constant time, especially if the element to be accessed is in the second block? Or does a deque have a pointer to the group of blocks? Update: Or is there any other common implementation for a deque?

• UITabBarController Modify [More ...] Appearance

  - by Mark

  Hello everyone, I would like to know if there is a way to change the text in the [More ...] tab. With the code below I am able to change the text in the view, however the text in the tab remains the same. Is there a way to access it and change it's appearance. tabBarController.moreNavigationController.topViewController.navigationItem.title = NSLocalizedString(@"Meer", ""); My second question is about the [Edit] button in the More view. The code below does not work. tabBarController.moreNavigationController.topViewController.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Wijzigen" style:UIBarButtonItemStyleDone target:nil action:nil]; Does anyone have an idea? Cheers.

• Writing the code by dividing it into more files in cocoatouch.

  - by srikanth rongali

  My problem is, I need a background image, a sprite(with animation) on left edge, another sprite(with animation) at other edge, a number count animation 1-2-3 at middle. I got all these when I wrote all in same file.(like [self addChild:label], [self addChild:sprite].., But in this it needs touch enables for both sprites separately, and touchDisabled to the remaining screen. So thought of writing in different files. But now it is not working. I kept one sprite, background image, numbercount in one file and another spritr in other file. Either I am getting the second sprite or the (sprite+background+numberCount) is displayed. This is my problem. plz give me solution. Thank You

• How to use a value from one stored procedure in another?

  - by RoguePlanetoid

  I have the following statement in a Stored Procedure: DECLARE @Count INT EXEC @Count = GetItemCount 123 SELECT @Count Which calls another stored procedure with the following statement inside: SELECT COUNT(Item) FROM tblItem WHERE ID = @ID However when I test the call the EXEC outputs the value correctly but it is not assigned to the @Count Variable correctly. I've seen examples or stored procedures used like this, including here but none had a parameter and a return value used (that I could find). The ID Parameter is passed into the second statement which returns a count value used by the first StoredProcedure - all the info I have read seems to indicate this should work - but it doesn't the @Count value is aways zero, even when the GetItemCount returns always the correct value. This is in Microsoft SQL Server 2008 if that helps.

• JSON Object XHR and closures

  - by Sara Chipps

  Hi all, I have a JSON object that is populated by an XHR. I then need to update that object with values from a separate XHR call. The issue I am running into is the second call isn't being made at the correct time and I think it's an issue with how I structured my object. Here is what I have: function Proprietary() { var proprietary= this; this.Groups = {}; this.getGroups = function() { $.getJSON(group_url, function(data){proprietary.callReturned(data);}); } this.callReturned = function(data) { //Do stuff for(var i=0; i< data.groups.length; i++) { insparq.Groups[i] = data.groups[i]; $.getJSON(participant_url, function(p){proprietary.Groups[i].participants = p;}); } //the function call below is the action I want to occur after the object is populated. PopulateGroups(); } };

• How to make this jpeg compression faster

  - by Richard Knop

  I am using OpenCV to compress binary images from a camera: vector<int> p; p.push_back(CV_IMWRITE_JPEG_QUALITY); p.push_back(75); // JPG quality vector<unsigned char> jpegBuf; cv::imencode(".jpg", fIplImageHeader, jpegBuf, p); The code above compresses a binary RGB image stored in fIplImageHeader to a JPEG image. For a 640*480 image it takes about 0.25 seconds to execute the five lines above. Is there any way I could make it faster? I really need to repeat the compression more than 4 times a second.

• Dowloading a bunch of files asynchronous wait till last finished

  - by Casper Broeren

  I'm trying to download a lot of files after downloading a sql statement must insert a record. I'm using System.Net.Client to download each file synchronously, still it could be done asynchronous. There's no relation or dependency between each download. At first I just tried to use WebClient.DownloadFileAsync but that shutted the program down and killed all the download processes/threads. Second I tried to create a wait routine something like this; while (processedFiles < totalFiles) Thread.Sleep(1000) This freezed everything. So could someone tell me which aproach to take to implement this Async?

• javascript: getting two sibling windows communicate

  - by romuwild

  i have 2 windows: window A and window B. -window A and window B have same domain -window A and window B doesn't have any parent window. first question: -is it possible for window A to get a reference of window B? second question: -what is the most elegant way to make window A notify something to window B? (modern browser supporting HTML5 restriction is not a problem) 2 ways i am aware of doing this: -messaging by server: where window B regulary asks the server if window A has notified something -messaging by local data (HTML5): when window A wants to notify something it changes the local data, window B regulary checks the local data for any change. but the 2 ways are not so elegant. for example it would be nice to get an reference of window B and using window.postMessage() (HTML5) ultimate goal is to make something like facebook where if you open 4 facebook tabs, and chat in one tab, the chat is actualized on every facebook tab, which is neat! thanks folks!

• APNS Sending Frequent Notifications to Device

  - by user564447

  I'm trying to mimic a pager with my app by sending push notifications to the user until he or she responds. My thought was to send a push every few seconds and play the default sound on arrival. Not perfect, but better than nothing. It's working all right. However, I am finding that the sound starts to stutter/interrupt a bit after a few notifications have been sent -- as if it's trying to play the sound more than once. This happens even if I only send the push every 10 seconds. I just tested it at 20 second intervals and even then it starts to sound interrupted after about 10 times. Any idea how to resolve this so each message plays the sound crisply? p.s. Testing performed on an iPad.

• Slow first page load on asp.net site

  - by Tabloo Quijico

  Hi, Every now and then (always after a long period of idle-time, e.g. overnight) when I access a site built using asp.net - it takes around 15 seconds to load the page (15 seconds before I see any progress whatsoever, then the page comes up fast). Further pages on that site, or refreshes, are quick as usual - they are also fast on other machines, only the first one seems to take the 'hit'. Page tracing never through anything up (whole cycle was a fraction of a second) So my question is where else should I be looking? Perhaps IIS? Or could it still be my asp.net app and I'm just looking in the wrong place (the trace) for clues? As I don't have much control over the IIS server, anything I can check through asp.net would be more helpful, before I go ask that particular admin. cheers :D

• Why in Objective-C, we use self = [super init] instead of just [super init]?

  - by ????

  In a book, I saw that if a subclass is overriding a superclass's method, we may have self = [super init]; First, is this supposed to be done in the subclass's init method? Second, I wonder why the call is not just [super init]; ? I mean, at the time of calling init, the memory is allocated by alloc already (I think by [Foobar alloc] where Foobar is the subclass's name. So can't we just call [super init] to initialize the member variables? Why do we have to get the return value of init and assign to self? I mean, before calling [super init], self should be pointing to a valid memory allocation chuck... so why assigning something to self again? (if assigning, won't [super init] just return self's existing value?)

• Excel can't remember how to copy/paste

  - by wootscootinboogie

  So, maybe someone else has an idea why this happens. I have a full-fledged version of Office 2007, works fine and all that jazz. However, if I try to copy and paste query results from SSMS, or anywhere else for that matter, I have to have an instance of Excel open and then paste. I can't copy, open Excel, and then paste. The little 'wait' circle pops up for a split second but nothing is pasted. I have never ran across this with any other program. Any good explanation for this? FFIW, it's Excel 2007 running in compatibility mode.
