  • Jeditable Datepicker onblur problem

    - by Shobha Deepthi
    Hi, I am using inline editing using Jeditable and datepicker. I have a column in my table which displays Date as a hyperlink. When I click on this it shows me the datepicker. And when a particular date is selected its updated in the backend and the cell now is updated with the changed value. However, am having problem with onblur event while changing month or years. This event gets triggered when I click on "Prev" or "Next" buttons on the datepicker control. This causes an exception when the date is selected. This works fine as long as the date selected is in the current month. I tried all possible solutions listed here: stackoverflow.com/questions/2007205/jeditable-datepicker-causing-blur-when-changing-month If settimeout the control does not change back to a normal hyperlink on closing the datepicker or on a true onblur event. Here's my code, $.editable.addInputType('datepicker', { element : function(settings, original) { var input = $(''); if (settings.width != 'none') { input.width(settings.width); } if (settings.height != 'none') { input.height(settings.height); } input.attr('autocomplete','off'); $(this).append(input); return(input); }, plugin : function(settings, original) { var form = this; settings.onblur = function(e) { t = setTimeout(function() { original.reset.apply(form, [settings, self]); }, 100); }; $(this).find('input').datepicker({ changeMonth: true, changeYear: true, dateFormat: 'dd-M-y', closeAtTop: true, onSelect: function(dateText) { $(this).hide(); $(form).trigger('submit'); } }); }, submit : function(settings, original) { } }); $(function() { $('.edit_eta').editable('update_must_fix_eta.php', { id: 'bugid', name: 'eta', type: 'datepicker', event: 'click', select : true, width: '50px', onblur:'cancel', cssclass : 'editable', indicator : 'Updating ETA, please wait.', style : 'inherit', submitdata:{version:'4.2(4)',tag:'REL_4_2_4',qstr:1} }); }); I tried hacking jeditable.js as mentioned on this link: http://groups.google.com/group/jquery-dev/browse_thread/thread/265340ea692a2f47 Even this does not help. Any help is appreciated.

  • Lisp Style question label local functions or not?

    - by Andrew Myers
    I was wondering if there is a standard practice regarding the use of labels in Lisp. I've been messing around with a Lisp implementation of the algorithm described in the first answer here http://stackoverflow.com/questions/352203/generating-permutations-lazily My current version uses labels to break out portions of functionality. (defun next-permutation (pmute) (declare (vector pmute)) (let ((len (length pmute))) (if (> len 2) (labels ((get-pivot () (do ((pivot (1- len) (1- pivot))) ((or (= pivot 0) (< (aref pmute (1- pivot)) (aref pmute pivot))) pivot))) (get-swap (pivot) (let ((swp (1- len))) (loop for i from (1- len) downto pivot do (if (or (and (> (aref pmute i) (aref pmute (1- pivot))) (< (aref pmute i) (aref pmute swp))) (< (aref pmute swp) (aref pmute (1- pivot)))) (setf swp i))) swp)) (next (swp pivot) (rotatef (aref pmute (1- pivot)) (aref pmute swp)) (reverse-vector pmute pivot (1- len)))) (let ((piv (get-pivot))) (if (> piv 0) (next (get-swap piv) piv) nil)))))) Since each label is only called once I was wondering if this is considered bad practice since the only reason to do it in this case is for aesthetic reasons. I would argue that the current version with labels is clearer but that may go against common wisdom that I'm not aware of, being new to Lisp.

  • Automatic INotifyPropertyChanged Implementation through T4 code generation?

    - by chrischu
    I'm currently working on setting up a new project of mine and was wondering how I could achieve that my ViewModel classes do have INotifyPropertyChanged support while not having to handcode all the properties myself. I looked into AOP frameworks but I think they would just blow up my project with another dependency. So I thought about generating the property implementations with T4. The setup would be this: I have a ViewModel class that declares just its Properties background variables and then I use T4 to generate the Property Implementations from it. For example this would be my ViewModel: public partial class ViewModel { private string p_SomeProperty; } Then T4 would go over the source file and look for member declarations named "p_" and generate a file like this: public partial class ViewModel { public string SomeProperty { get { return p_SomeProperty; } set { p_SomeProperty= value; NotifyPropertyChanged("SomeProperty"); } } } This approach has some advantages but I'm not sure if it can really work. So I wanted to post my idea here on StackOverflow as a question to get some feedback on it and maybe some advice how it can be done better/easier/safer.

  • How to avoid reallocation using the STL (C++)

    - by Tue Christensen
    This question is derived of the topic: http://stackoverflow.com/questions/2280655/vector-reserve-c I am using a datastructur of the type vector<vector<vector<double> > >. It is not possible to know the size of each of these vector (except the outer one) before items (doubles) are added. I can get an approximate size (upper bound) on the number of items in each "dimension". A solution with the shared pointers might be the way to go, but I would like to try a solution where the vector<vector<vector<double> > > simply has .reserve()'ed enough space (or in some other way has allocated enough memory). Will A.reserve(500) (assumming 500 is the size or, alternatively an upper bound on the size) be enough to hold "2D" vectors of large size, say [1000][10000]? The reason for my question is mainly because I cannot see any way of reasonably estimating the size of the interior of A at the time of .reserve(500). An example of my question: vector A; A.reserve(500+1); vector temp2; vector temp1 (666,666); for(int i=0;i<500;i++) { A.push_back(temp2); for(int j=0; j< 10000;j++) { A.back().push_back(temp1); } } Will this ensure that no reallocation is done for A? If temp2.reserve(100000) and temp1.reserve(1000) where added at creation will this ensure no reallocation at all will occur at all? In the above please disregard the fact that memory could be wasted due to conservative .reserve() calls. Thank you all in advance!

  • How to print data form C#

    - by Hybryd
    I've searched Stackoverflow and google and found many ways how I can print stuff in C#. The best way for me would be to populate blank white windows form with some label, textbox and picturebox elements and print it as a windows form. This way is very poor because it prints in 72 DPI, and is not flexible for multiple pages print. Next way that I found that would be good is using iTextSharp, but there is a problem that iTextSharp only generates PDF-s, and you have to open it in PDF viewer and print from there. I love this way of thinking where I create a paragraph, and then fill it with text and graphic, so I found this thread http://www.devarticles.com/c/a/C-Sharp/Printing-Using-C-sharp/ where it discusses how to create your own printing engine in C#, something like iTextSharp, but very lightweight... Now that I've said that, I want to know is there any ready to use printing engine that would be like iTextSharp, made for printing, not for PDF generation? What is the best way to print something, without using reporting services like CrystalReports. I think Crystal Reports wouldn't work for my case cause I don't want to print generic reports, but some text and graphics that I need to dynamicaly generate every time I need to print.

  • Excluding a script from the general UrlRewrite rules

    - by Steven
    Hi, I have following rewrite rules for a website: RewriteEngine On # Stop reading config files RewriteCond %{REQUEST_FILENAME} .*/web.config$ [NC,OR] RewriteCond %{REQUEST_FILENAME} .*/\.htaccess$ [NC] RewriteRule ^(.+)$ - [F] # Rewrite to url RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !^(/bilder_losning/|/bilder/|/gfx/|/js/|/css/|/doc/).* RewriteRule ^(.+)$ index.cfm?smartLinkKey=%{REQUEST_URI} [L] Now I have to exclude a script including its eventually querystrings from the above rules, so that I can access and execute it on the normal way, at the moment the whole url is being ignored and forwarded to the index page. I need to have access to the script shoplink.cfm in the root which takes variables tduid and url (shoplink.cfm?tduid=1&url=) I have tried to resolve it using this: # maybe?: RewriteRule !(^/shoplink.cfm [QSA] but to be honest, I have not much of a clue of urlrewriting and have no idea what I am supposed to write. I just know that above will generate a nice 500 error. I have been looking around a lot on stackoverflow and other websites on the same subject, but all I see is people trying to exclude directories, not files. In the worst case I could add the script to a seperate directory and exclude the directory from the rewriterules, but rather not since the script should really remain in the root. Just also tried: RewriteRule ^/shoplink.cfm$ $0 [L] but that didn't do anything either. Anyone who can help me out on this subject? Thanks in advance. Steven Esser ColdFusion programmer

  • OutOfMemoryException, large Private Data

    - by Captain Comic
    Hello, In previous series: http://stackoverflow.com/questions/2543648/outofmemoryexception-stack-size-is-huge-large-number-of-threads I have a .net windows service that consumes a lot of memory. The GC heap is not big. Also the stack size is not big. What is big is something called a private data. Also I can see in task manager that my application consumes a lot something that taskmanager calls a handle. My application consumes 2326 handles. I believe that these handles are some windows handles that occupy private data. I can see that this private data is occupied by blocks marked as Thread Environment Block. What is that? Screenshot of my application memory usage by VMMap Screenshot of my application memory usage by Task Manager UPDATE I run ProcessExplorer. I have two instances of my service running at the moment. I can see that they consume a lot of virtual memory for Gen2 GC. This look suspicios. Also total reserved for GC Heap size is the same for two processes.

  • AutoMapper a viable alternative to two way databinding using a FormView?

    - by tbone
    I've started using the FormView control to enable two way databinding in asp.net webforms. I liked that it saved me the trouble of writing loadForm and unloadForm routines on every page. So it seemed to work nicely at the start when I was just using textboxes everywhere....but when it came time to start converting some to DropDownLists, all hell broke lose. For example, see: http://stackoverflow.com/questions/2435185/not-possible-to-load-dropdownlist-on-formview-from-code-behind ....and I had many additional problems after that. So I happened upon an article on AutoMapper, which I know very little about yet, but from the sounds of it, this might be a viable alternative to two-way databinding a form to an domain entity object? From what I understand, AutoMapper basically operates on naming convention, so, it will look for matched names properties(?) on the source and destination objects. So, basically, I have all my domain entities (ie: Person) with properties (FirstName, LastName, Address, etc)....what I would like to be able to do is declare my asp controls with those exact same names, and have automapper do the loading and unloading. One obvious caveat is that AutoMapper would have to know the proper property name for each control type, ie: Person.FirstName -- form.FirstName*.Text* Person.Country -- form.Country.SelectedValue Person.IsVerified -- form.IsVerified.Checked ....so it would have to have the smarts to find the control on the form, determine its type, and then load/unload between the domain object and the webform control into the proper property of the control. So if this worked, a person could just get rid of the cursed FormView control entirely, and it would be just one line of code each for binding and unbinding a webform. Possible?

  • Can someone please explain this lazy evaluation code?

    - by Tejs
    So, this question was just asked on SO: http://stackoverflow.com/questions/2740001/how-to-handle-an-infinite-ienumerable My sample code: public static void Main(string[] args) { foreach (var item in Numbers().Take(10)) Console.WriteLine(item); Console.ReadKey(); } public static IEnumerable<int> Numbers() { int x = 0; while (true) yield return x++; } Can someone please explain why this is lazy evaluated? I've looked up this code in Reflector, and I'm more confused than when I began. Reflector outputs: public static IEnumerable<int> Numbers() { return new <Numbers>d__0(-2); } For the numbers method, and looks to have generated a new type for that expression: [DebuggerHidden] public <Numbers>d__0(int <>1__state) { this.<>1__state = <>1__state; this.<>l__initialThreadId = Thread.CurrentThread.ManagedThreadId; } This makes no sense to me. I would have assumed it was an infinite loop until I put that code together and executed it myself.

  • GNU Make: How to call $(wildcard) within $(eval)

    - by bengineerd
    I'm trying to create a generic build template for my Makefiles, kind of like they discuss in the eval documentation. I can't seem to get the wildcard function to work within an eval. The basic code I'm having issues with looks like this. SRC_DIR = ./src/ PROG_NAME = test define PROGRAM_template $(1)_SRC_DIR = $(join $(SRC_DIR), $(1)/) $(1)_SRC_FILES = $(wildcard $$($(1)_SRC_DIR)*.c) endef $(eval $(call PROGRAM_template, $(PROG_NAME))) all: @echo $(test_SRC_DIR) @echo $(test_SRC_FILES) @echo $(wildcard $(wildcard $(test_SRC_DIR)*.c) When I run make with this, the output is ./src/test [correct list of all .c files in ./src/test/] Basically, the wildcard call within PROGRAM_template is not being eval'd as I expect it. The call results in an empty list. The join call is being eval'd correctly though. So, what am I doing wrong? My guess is that $$($(1)_SRC_DIR) is not correct, but I can't figure out the right way to do it. EDIT Once this was solved, it didn't take long for me to hit another issue with eval. I posted it as a new question at http://stackoverflow.com/questions/2428506/workaround-for-gnu-make-3-80-eval-bug

  • Unable to convert from Julian INT date to regular TSQL Datetime

    - by Bluehiro
    Help me Stackoverflow, I'm close to going all "HULK SMASH" on my keyboard over this issue. I have researched carefully but I'm obviously not getting something right. I am working with a Julian dates referenced from a proprietary tool (Platinum SQL?), though I'm working in SQL 2005. I can convert their "special" version of Julian into datetime when I run a select statement. Unfortunately it will not insert into a datetime column, I get the following error when I try: The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value. So I can't setup datetime criteria for running a report off of the Stored Procedure. Original Value: 733416 Equivalent Calendar Value: 01-09-2009 Below is my code... I'm so close but I can't quite see what's wrong, I need my convert statement to actually convert the Julian value (733416) into a compatible TSQL DATETIME value. SELECT org_id, CASE WHEN date_applied = 0 THEN '00-00-00' ELSE convert(char(50),dateadd(day,date_applied-729960,convert(datetime, '07-25-99')),101) END AS date_applied, CASE WHEN date_posted = 0 THEN '00-00-00' ELSE convert(char(50),dateadd(day,date_posted-729960,convert(datetime, '07-25-99')),101) END AS date_posted from general_vw

  • ASP.NET MVC and ViewState

    - by nickyt
    Now I've seen some questions like this, but it's not exactly what I want to ask, so for all those screaming duplicate, I apologize :). I've barely touched ASP.NET MVC but from what I understand there is no ViewState/ControlState... fine. So my question is what is the alternative to retaining a control's state? Do we go back to old school ASP where we might simulate what ASP.NET ViewState/ControlState does by creating hidden form inputs with the control's state, or with MVC, do we just assume AJAX always and retain all state client-side and make AJAX calls to update? This question has some answers, http://stackoverflow.com/questions/1285547/maintaining-viewstate-in-asp-net-mvc, but not exactly what I'm looking for in an answer. UPDATE: Thanks for all the answers so far. Just to clear up what I'm not looking for and what I'm looking for: Not looking for: Session solution Cookie solution Not looking to mimic WebForms in MVC What I am/was looking for: A method that only retains the state on postback if data is not rebound to a control. Think WebForms with the scenario of only binding a grid on the initial page load, i.e. only rebinding the data when necessary. As I mentioned, I'm not trying to mimic WebForms, just wondering what mechanisms MVC offers.

  • Inheriting from ViewPage forces explicit casting of model in view

    - by Martin Hansen
    I try to inhering from ViewPage as shown in this question http://stackoverflow.com/questions/370500/inheriting-from-viewpage But I get a Compiler Error Message: CS1061: 'object' does not contain a definition for 'Spot' and no extension method 'Spot' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) My viewpage, normally I can do Model.ChildProperty(Spot) when I inherit from ViewPage directly, so I do that here too. But it fails. <%@ Page Language="C#" Inherits="Company.Site.ViewPageBase<WebSite.Models.SpotEntity>" %> <h1><%= Html.Encode(Model.Spot.Title) %></h1> To get it working correctly I have to do like this: <%@ Page Language="C#" Inherits="Company.Site.ViewPageBase<WebSite.Models.SpotEntity>" %> <h1><%= Html.Encode(((WebSite.Models.SpotEntity)Model).Spot.Title) %></h1> Here is my classes: namespace Company.Site { public class ViewPageBase<TModel> : Company.Site.ViewPageBase where TModel:class { private ViewDataDictionary<TModel> _viewData; [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")] public new ViewDataDictionary<TModel> ViewData { get { if (_viewData == null) { SetViewData(new ViewDataDictionary<TModel>()); } return _viewData; } set { SetViewData(value); } } protected override void SetViewData(ViewDataDictionary viewData) { _viewData = new ViewDataDictionary<TModel>(viewData); base.SetViewData(_viewData); } } public class ViewPageBase : System.Web.Mvc.ViewPage { } } So how do I get it to work without the explicit cast?

  • Reading a POP3 server with only TcpClient and StreamWriter/StreamReader

    - by WebDevHobo
    I'm trying to read mails from my live.com account, via the POP3 protocol. I've found the the server is pop3.live.com and the port if 587. I'm not planning on using a pre-made library, I'm using NetworkStream and StreamReader/StreamWriter for the job. I need to figure this out. So, any of the answers given here: http://stackoverflow.com/questions/44383/reading-email-using-pop3-in-c are not usefull. It's part of a larger program, but I made a small test to see if it works. Eitherway, i'm not getting anything. Here's the code I'm using, which I think should be correct. public Program() { string temp = ""; using(TcpClient tc = new TcpClient(new IPEndPoint(IPAddress.Parse("127.0.0.1"),8000))) { tc.Connect("pop3.live.com",587); using(NetworkStream nws = tc.GetStream()) { using(StreamReader sr = new StreamReader(nws)) { using(StreamWriter sw = new StreamWriter(nws)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); while(temp != ".") { temp += sr.ReadLine(); } } } } } Console.WriteLine(temp); } So, I'm sending from port 8000 on my machine to port 587, the hotmail pop3 port. And I'm getting nothing, and I'm out of ideas.

  • Get paperclip to crop the image without validating

    - by Micke
    Hello fellow stackoverflow members. I have been following this guide to enable users to have their own avatar. But i have bumped in to a litle problem. When the user is cropping the image the model tries to validate all my validations. My user model looks like this: class User < ActiveRecord::Base has_attached_file :avatar, :styles => { :small => "100x100>", :large => "500x500>" }, :processors => [:cropper] attr_accessor :password, :crop_x, :crop_y, :crop_w, :crop_h attr_accessible :crop_x, :crop_y, :crop_w, :crop_h validates_confirmation_of :password validates_presence_of :password And when the user runs the crop updating script the user model tries to validate the password. But because i have no password field on the cropping page it can't validate it. Here is the updating of the crop: @user = User.find(current_user.id) if @user.update_attributes(params[:user]) flash[:notice] = "Successfully updated user." end How can i bypass this in a easy and clean way?

  • String assembly by StringBuilder vs StringWriter and PrintWriter

    - by CPerkins
    I recently encountered an idiom I haven't seen before: string assembly by StringWriter and PrintWriter. I mean, I know how to use them, but I've always used StringBuilder. Is there a concrete reason for preferring one over the other? The StringBuilder method seems much more natural to me, but is it just style? I've looked at several questions here (including this one which comes closest: http://stackoverflow.com/questions/602279/stringwriter-or-stringbuilder ), but none in which the answers actually address the question of whether there's a reason to prefer one over the other for simple string assembly. This is the idiom I've seen and used many many times: string assembly by StringBuilder: public static String newline = System.getProperty("line.separator"); public String viaStringBuilder () { StringBuilder builder = new StringBuilder(); builder.append("first thing" + newline); builder.append("second thing" + newline); // ... several things builder.append("last thing" + newline); return builder.toString(); } And this is the new idiom: string assembly by StringWriter and PrintWriter: public String viaWriters() { StringWriter stringWriter = new StringWriter(); PrintWriter printWriter = new PrintWriter(stringWriter); printWriter.println("first thing"); printWriter.println("second thing"); // ... several things printWriter.println("last thing"); printWriter.flush(); printWriter.close(); return stringWriter.toString(); }

  • C# Active Directory - Check username / password

    - by Michael G
    I'm using the following code on Windows Vista Ultimate SP1 to query our active directory server to check the user name and password of a user on a domain. public Object IsAuthenticated() { String domainAndUsername = strDomain + @"\" + strUser; DirectoryEntry entry = new DirectoryEntry(_path, domainAndUsername, strPass); SearchResult result; try { //Bind to the native AdsObject to force authentication. DirectorySearcher search = new DirectorySearcher(entry) { Filter = ("(SAMAccountName=" + strUser + ")") }; search.PropertiesToLoad.Add("givenName"); // First Name search.PropertiesToLoad.Add("sn"); // Last Name search.PropertiesToLoad.Add("cn"); // Last Name result = search.FindOne(); if (null == result) { return null; } //Update the new path to the user in the directory. _path = result.Path; _filterAttribute = (String)result.Properties["cn"][0]; } catch (Exception ex) { return new Exception("Error authenticating user. " + ex.Message); } return user; } the target is using .NET 3.5, and compiled with VS 2008 standard I'm logged in under a domain account that is a domain admin where the application is running. The code works perfectly on windows XP; but i get the following exception when running it on Vista: System.DirectoryServices.DirectoryServicesCOMException (0x8007052E): Logon failure: unknown user name or bad password. at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail) at System.DirectoryServices.DirectoryEntry.Bind() at System.DirectoryServices.DirectoryEntry.get_AdsObject() at System.DirectoryServices.DirectorySearcher.FindAll(Boolean findMoreThanOne) at System.DirectoryServices.DirectorySearcher.FindOne() at Chain_Of_Custody.Classes.Authentication.LdapAuthentication.IsAuthenticated() at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail) at System.DirectoryServices.DirectoryEntry.Bind() at System.DirectoryServices.DirectoryEntry.get_AdsObject() at System.DirectoryServices.DirectorySearcher.FindAll(Boolean findMoreThanOne) at System.DirectoryServices.DirectorySearcher.FindOne() at Chain_Of_Custody.Classes.Authentication.LdapAuthentication.IsAuthenticated() I've tried changing the authentication types, I'm not sure what's going on.

  • How to dynamically set control IDs inside a repeater template?

    - by Bryan
    Here is a perplexing issue I have not seen a good answer to on StackOverflow, although there a couple stabs at it... I have a situation where I'd like to do this: <asp:Repeater ID="MyRepeater" runat="server" OnItemDataBound="MyRepeater_ItemDataBound"> <ItemTemplate> <li id="id?"> All the other stuff </li> </ItemTemplate> </asp:Repeater> The question... is how do I get the ID of my <li> elements to be id1, id2, id3, etc., based on the ItemIndex they are bound to? So far the most... er..."elegant" solution I've come up with is to replace the <li> with an asp:Literal and dump the <li...>' text. But that just feels... so wrong. And no, I'm not using ASP.NET 4.0, which I've read will provide this functionality.

  • TypeConverter prevents ApplyPropertyChanges in EntityFramework

    - by Felix
    I ran into an interesting problem (hopefully, interesting not just for me :) I am running Entity Framework 1 (.NET 3.5) and ASP.NET MVC 2. I have a Customer class that has many-to-one relationship with Country class (in other words, Country is a lookup table for customers - I described more in this post: http://stackoverflow.com/questions/2404801/explicit-casting-doesnt-work-in-default-model-binding ) I got TypeConverter to work; so I am getting a perfect object into controller's Post method. Create works fine; however, in Edit I am getting the following error when I call ApplyPropertyChanges: The existing object in the ObjectContext is in the Added state. Changes can only be applied when the existing object is in an unchanged or modified state. The controller code is fairly trivial: public ActionResult Edit(Customer customerToEdit) { if (ModelState.IsValid) { Customer cust = (Customer)context.GetObjectByKey( new EntityKey("BAEntities.Customers", "CustomerID", customerToEdit.CustomerID)); context.ApplyPropertyChanges(cust.EntityKey.EntitySetName, customerToEdit); context.SaveChanges(); } return View(...); } If I remove country from the form, it works fine; and if I assign dropdown value to EntityReference "manually" - it works as well. TypeConverter code is also fairly simple, but I've never used TypeConverter before, so I may be missing something here: public override object ConvertFrom(ITypeDescriptorContext typeContext, CultureInfo culture, object value) { if (value is string) { int countryID = Int16.Parse((string)value); Country country = (Country)context.GetObjectByKey( new EntityKey("BAEntities.Countries", "CountryID", countryID)); return country; } return base.ConvertFrom(typeContext, culture, value); }

  • C# Path Ellipsis without Win32 API call revisited

    - by casterle
    I was searching for a way to insert an ellipsis in a C# path, and found an answer here on stackoverflow: http://tinyurl.com/y6rmdfr Using the RTM versions of VS2010 and .Net 4.0, I was unable to get the suggested method to work. I searched the 'Net and found example code that uses the same method, but it failed in the same way. You can see the string I'm trying to shorten in my code below. After calling the MeasureText method, both the input string (OriginalName) and the output string (ellipsisedName) look like this: d:\abcd\efgh\ijkl\mnop\qrst\...\test.txt\0F\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt Two problems: 1) The resulting string is narfed (the path is truncated as expected, but is followed by what looks like a C-style terminating null and a chunk of the original path). 2) My original string is changed to be identical to the output string. Am I doing something wrong? namespace WindowsFormsApplication2 { public partial class Form1 : Form { public Form1() { InitializeComponent(); string OriginalPath = @"d:\abcd\efgh\ijkl\mnop\qrst\uvwx\yzAB\CDEF\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt"; string ellipsisedPath = OriginalPath; Size proposedSize = new Size(label1.Width, label1.Height); TextRenderer.MeasureText(ellipsisedPath, label1.Font, proposedSize, TextFormatFlags.ModifyString | TextFormatFlags.PathEllipsis); } } }

  • Formatting and pretty printing dates with jquery

    - by Tauren
    I need to display dates in a couple different ways in an app built with jquery. In some situations, I need the typical "yyyy-mm-dd hh:mma" type of formatting, with all of it's different permutations. In other cases, I need to show dates "pretty printed" similar to how StackOverflow does them: 5 seconds ago 12 minutes ago 3 hours ago yesterday 2 days ago My application already uses JQuery UI DatePicker which includes a formatDate() function, but as far as I can tell, there is no way to use it outside of the datepicker. I want to format dates that aren't associated with a datepicker. Is it possible to do this using DatePicker? The DateJS library can parse dates like "12 minutes ago", but as far as I can tell, it cannot take a Date object and format strings like this. It can format the typical "yyyy-mm-dd" types of formats. This library seems pretty heavy as well. John Resig's Pretty Dates looks like it can provide the pretty printing ("2 hours ago"), but it doesn't do the standard formatting. Is there not a single plugin that can do all of this? Is there a way to leverage the DatePicker code so I don't have to load multiple codebases that do the same things?

  • BN_hex2bn magicaly segfaults in openSSL

    - by xunil154
    Greetings, this is my first post on stackoverflow, and i'm sorry if its a bit long. I'm trying to build a handshake protocol for my own project and am having issues with the server converting the clients RSA's public key to a Bignum. It works in my clent code, but the server segfaults when attempting to convert the hex value of the clients public RSA to a bignum. I have already checked that there is no garbidge before or after the RSA data, and have looked online, but i'm stuck. header segment: typedef struct KEYS { RSA *serv; char* serv_pub; int pub_size; RSA *clnt; } KEYS; KEYS keys; Initializing function: // Generates and validates the servers key /* code for generating server RSA left out, it's working */ //Set client exponent keys.clnt = 0; keys.clnt = RSA_new(); BN_dec2bn(&keys.clnt->e, RSA_E_S); // RSA_E_S contains the public exponent Problem code (in Network::server_handshake): // *Recieved an encrypted message from the network and decrypt into 'buffer' (1024 byte long)* cout << "Assigning clients RSA" << endl; // I have verified that 'buffer' contains the proper key if (BN_hex2bn(&keys.clnt->n, buffer) < 0) { Error("ERROR reading server RSA"); } cout << "clients RSA has been assigned" << endl; The program segfaults at BN_hex2bn(&keys.clnt->n, buffer) with the error (valgrind output) Invalid read of size 8 at 0x50DBF9F: BN_hex2bn (in /usr/lib/libcrypto.so.0.9.8) by 0x40F23E: Network::server_handshake() (Network.cpp:177) by 0x40EF42: Network::startNet() (Network.cpp:126) by 0x403C38: main (server.cpp:51) Address 0x20 is not stack'd, malloc'd or (recently) free'd Process terminating with default action of signal 11 (SIGSEGV) Access not within mapped region at address 0x20 at 0x50DBF9F: BN_hex2bn (in /usr/lib/libcrypto.so.0.9.8) And I don't know why it is, Im using the exact same code in the client program, and it works just fine. Any input is greatly appriciated!
