• More outlook VSTO help...

  - by Jerry

  I posted an article here (http://stackoverflow.com/questions/1095195/how-do-i-set-permissions-on-my-vsto-outlook-add-in) and I was able to build my installer. I thought that once the installer built itself, everything would work fine. I was wrong. It works on about half of the PC's I've run the installer on. My problem is that the other half doesn't work. I'm trying to install an add-in to Outlook Office 2003. I've even gone so far as to create the steps manually by using a batch file. Nothing seems to work on these PCs and I can't find a common denominator that I can rule out or in that will make the VSTO Addin work. Here is the batch file I am using. What am I doing/not-doing wrong with this? I could really use a VSTO expert's help. Thanks!!!! EDIT I've changed the batch file and registry settings to reflect recent updates to them. I've also attached the error text that comes from the PCs that don't work. @echo off echo Installing Visual Studio for Office Runtime (SE 2005)... ..\VSTO\vstor.exe echo Creating Directories... mkdir "c:\program files\Project Archiver" echo Installying Add-In... echo Copying files... xcopy /Y *.dll "c:\program files\Project Archiver" xcopy /Y *.manifest "c:\program files\Project Archiver" echo Setting Security...

• AT91SAM7X512's SPI peripheral gets disabled on write to SPI_TDR

  - by Dor

  My AT91SAM7X512's SPI peripheral gets disabled on the X time (X varies) that I write to SPI_TDR. As a result, the processor hangs on the while loop that checks the TDRE flag in SPI_SR. This while loop is located in the function SPI_Write() that belongs to the software package/library provided by ATMEL. The problem occurs arbitrarily - sometimes everything works OK and sometimes it fails on repeated attempts (attemp = downloading the same binary to the MCU and running the program). Configurations are (defined in the order of writing): SPI_MR: MSTR = 1 PS = 0 PCSDEC = 0 PCS = 0111 DLYBCS = 0 SPI_CSR[3]: CPOL = 0 NCPHA = 1 CSAAT = 0 BITS = 0000 SCBR = 20 DLYBS = 0 DLYBCT = 0 SPI_CR: SPIEN = 1 After setting the configurations, the code verifies that the SPI is enabled, by checking the SPIENS flag. I perform a transmission of bytes as follows: const short int dataSize = 5; // Filling array with random data unsigned char data[dataSize] = {0xA5, 0x34, 0x12, 0x00, 0xFF}; short int i = 0; volatile unsigned short dummyRead; SetCS3(); // NPCS3 == PIOA15 while(i-- < dataSize) { mySPI_Write(data[i]); while((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TXEMPTY) == 0); dummyRead = SPI_Read(); // SPI_Read() from Atmel's library } ClearCS3(); /**********************************/ void mySPI_Write(unsigned char data) { while ((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TXEMPTY) == 0); AT91C_BASE_SPI0->SPI_TDR = data; while ((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TDRE) == 0); // <-- This is where // the processor hangs, because that the SPI peripheral is disabled // (SPIENS equals 0), which makes TDRE equal to 0 forever. } Questions: What's causing the SPI peripheral to become disabled on the write to SPI_TDR? Should I un-comment the line in SPI_Write() that reads the SPI_RDR register? Means, the 4th line in the following code: (The 4th line is originally marked as a comment) void SPI_Write(AT91S_SPI *spi, unsigned int npcs, unsigned short data) { // Discard contents of RDR register //volatile unsigned int discard = spi->SPI_RDR; /* Send data */ while ((spi->SPI_SR & AT91C_SPI_TXEMPTY) == 0); spi->SPI_TDR = data | SPI_PCS(npcs); while ((spi->SPI_SR & AT91C_SPI_TDRE) == 0); } Is there something wrong with the code above that transmits 5 bytes of data? Please note: The NPCS line num. 3 is a GPIO line (means, in PIO mode), and is not controlled by the SPI controller. I'm controlling this line by myself in the code, by de/asserting the ChipSelect#3 (NPCS3) pin when needed. The reason that I'm doing so is because that problems occurred while trying to let the SPI controller to control this pin. I didn't reset the SPI peripheral twice, because that the errata tells to reset it twice only if I perform a reset - which I don't do. Quoting the errata: If a software reset (SWRST in the SPI Control Register) is performed, the SPI may not work properly (the clock is enabled before the chip select.) Problem Fix/Workaround The SPI Control Register field, SWRST (Software Reset) needs to be written twice to be cor- rectly set. I noticed that sometimes, if I put a delay before the write to the SPI_TDR register (in SPI_Write()), then the code works perfectly and the communications succeeds. Useful links: AT91SAM7X Series Preliminary.pdf ATMEL software package/library spi.c from Atmel's library spi.h from Atmel's library An example of initializing the SPI and performing a transfer of 5 bytes is highly appreciated and helpful.

• Run javascript after form submission in update panel?

  - by AverageJoe719

  This is driving me crazy! I have read at least 5 questions on here closely related to my problem, and probably 5 or so more pages just from googling. I just don't get it. I am trying to have a jqueryui dialog come up after a user fills out a form saying 'registration submitted' and then redirecting to another page, but I cannot for the life of me get any javascript to work, not even a single alert. Here is my update panel: <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="upForm" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="False"> <ContentTemplate> 'Rest of form' <asp:Button ID="btnSubmit" runat="server" Text="Submit" /> <p>Did register Pass? <%= registrationComplete %></p> </ContentTemplate> </asp:UpdatePanel> The Jquery I want to execute: (Right now this is sitting in the head of the markup, with autoOpen set to false) <script type="text/javascript"> function pageLoad() { $('#registerComplete').dialog({ autoOpen: true, width: 270, resizable: false, modal: true, draggable: false, buttons: { "Ok": function() { window.location.href = "someUrl"; } } }); } </script> Finally my code behind: ( Commented out all the things I've tried) Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSubmit.Click 'Dim sbScript As New StringBuilder()' registrationComplete = True registrationUpdatePanel.Update() 'sbScript.Append("<script language='JavaScript' type='text/javascript'>" + ControlChars.Lf)' 'sbScript.Append("<!--" + ControlChars.Lf)' 'sbScript.Append("window.location.reload()" + ControlChars.Lf)' 'sbScript.Append("// -->" + ControlChars.Lf)' 'sbScript.Append("</")' 'sbScript.Append("script>" + ControlChars.Lf)' 'ScriptManager.RegisterClientScriptBlock(Me.Page, Me.GetType(), "AutoPostBack", sbScript.ToString(), False)' 'ClientScript.RegisterStartupScript("AutoPostBackScript", sbScript.ToString())' 'Response.Write("<script type='text/javascript'>alert('Test')</script>")' 'Response.Write("<script>windows.location.reload()</script>")' End Sub I've tried: Passing variables from server to client via inline <%= % in the javascript block of the head tag. Putting that same code in a script tag inside the updatePanel. Tried to use RegisterClientScriptBlock and RegisterStartUpScript Just doing a Response.Write with the script tag written in it. Tried various combinations of putting the entire jquery.dialog code in the registerstartup script, or just trying to change the autoOpen property, or just calling "open" on it. I can't even get a simple alert to work with any of these, so I am doing something wrong but I just don't know what it is. Here is what I know: The Jquery is binding properly even on async postbacks, because the div container that is the dialog box is always invisible, I saw a similiar post on here stating that was causing an issue, this isn't the case here. Using page_load instead of document.ready since that is supposed to run on both async and normal postbacks, so that isn't the issue. The update panel is updating correctly because <p>Did register Pass? <%= registrationComplete %></p> updates to true after I submit the form. So how can I make this work? All I want is - click submit button inside an update panel - run server side code to validate form and insert into db - if everything succeeded, have that jquery (modal) dialog pop up saying hey it worked.

• ASP.NET MVC 2 Model encapsulated within ViewModel Validation

  - by Program.X

  I am trying to get validation to work in ASP.NET MVC 2, but without much success. I have a complex class containing a large number of fields. (Don't ask - this is oneo f those real-world situations best practices can't touch) This would normally be my Model and is a LINQ-to-SQL generated class. Because this is generated code, I have created a MetaData class as per http://davidhayden.com/blog/dave/archive/2009/08/10/AspNetMvc20BuddyClassesMetadataType.aspx. public class ConsultantRegistrationMetadata { [DisplayName("Title")] [Required(ErrorMessage = "Title is required")] [StringLength(10, ErrorMessage = "Title cannot contain more than 10 characters")] string Title { get; set; } [Required(ErrorMessage = "Forename(s) is required")] [StringLength(128, ErrorMessage = "Forename(s) cannot contain more than 128 characters")] [DisplayName("Forename(s)")] string Forenames { get; set; } // ... I've attached this to the partial class of my generated class: [MetadataType(typeof(ConsultantRegistrationMetadata))] public partial class ConsultantRegistration { // ... Because my form is complex, it has a number of dependencies, such as SelectLists, etc. which I have encapsulated in a ViewModel pattern - and included the ConsultantRegistration model as a property: public class ConsultantRegistrationFormViewModel { public Data.ConsultantRegistration ConsultantRegistration { get; private set; } public SelectList Titles { get; private set; } public SelectList Countries { get; private set; } // ... So it is essentially ViewModel=Model My View then has: <p> <%: Html.LabelFor(model => model.ConsultantRegistration.Title) %> <%: Html.DropDownListFor(model => model.ConsultantRegistration.Title, Model.Titles,"(select a Title)") %> <%: Html.ValidationMessage("Title","*") %> </p> <p> <%: Html.LabelFor(model => model.ConsultantRegistration.Forenames) %> <%: Html.TextBoxFor(model => model.ConsultantRegistration.Forenames) %> <%: Html.ValidationMessageFor(model=>model.ConsultantRegistration.Forenames) %> </p> The problem is, the validation attributes on the metadata class are having no effect. I tried doing it via an Interface, but also no effect. I'm beginning to think that the reason is because I am encapsulating my model within a ViewModel. My Controller (Create Action) is as follows: [HttpPost] public ActionResult Create(Data.ConsultantRegistration consultantRegistration) { if (ModelState.IsValid) // this is always true - which is wrong!! { try { consultantRegistration = ConsultantRegistrationRepository.SaveConsultantRegistration(consultantRegistration); return RedirectToAction("Edit", new { id = consultantRegistration.ID, sectionIndex = 2 }); } catch (Exception ex) { ModelState.AddModelError("CreateException",ex); } } return View(new ConsultantRegistrationFormViewModel(consultantRegistration)); } As outlined in the comment, the ModelState.IsValid property always returns true, despite fields with the Validaiton annotations not being valid. (Forenames being a key example). Am I missing something obvious - considering I am an MVC newbie? I'm after the mechanism demoed by Jon Galloway at http://www.asp.net/learn/mvc-videos/video-10082.aspx. (Am aware t is similar to http://stackoverflow.com/questions/1260562/asp-net-mvc-model-viewmodel-validation but that post seems to talk about xVal. I have no idea what that is and suspect it is for MVC 1)

• Most simple way to do holiday calculation?

  - by brainfrog

  I want to make a little free calendar program to help me and others calculate how much time we have got left in a project. I mean real working time, not just time. Time in a raw form is not saying much. Typically when my boss tells me that I have time until 05-05-2011 it doesn't tell me really how much time I have to do my job. You know...so many things stop me from work: A) beeing at home, not at work (so called "free time" or "spare time"). That is in my case I work exactly 8 hours a day and then the cleaning ladies throw me out of the office with their incredible loud industrial vacuum cleaners every evening (my boss accepts that as an excuse to go home in time, regularly). B) weekends, or more precisely saturdays and sundays C) official holiday rescuing me from having to go to work. what I want to do is make a little utility which tells me how many working hours I really have in a given time period. The first two things A and B are pretty easy to implement. But the last thing C scares my pants off. Holidays. OOOHHH man. You know what that means. Chaos. Pure chaos. The huge question is: HOW TO CALCULATE HOLIDAYS?! Since I want my program to be useful for anyone anywhere in the world, I can't just hardcode all holidays for my little town. So which options do I have? I) I could hand-craft downloadable lists of holidays. Users search them within the application and download them from an webserver. Or I ship all of them in the package. But I would get very, very old if I tried that by myself for every country, state and town. II) I make an initial data sheet with holidays for my town, and don't care about the rest. However, I make that sheet with an how-to public, so that everyone who feels like beeing very nice can provide holiday data for his country / region / whatever. Those are made public on a webserver and everyone can get the data packages he/she needs for the app. III) ? I care a lot about usability. I don't want to make an ugly linux hack style hard to use app that only computer freaks can use. So you need to tell me more about holiday science. I was never really clever at this. I assume every single country in the world has it's own set of holidays. In every country there may be several states. For example the US has some, and Germany has also some states. Holidays vary from state to state. But I know from an good programmer he told me never assume anything. So the questions about holiday science are: Which categories do I need to make holiday-data-packs searchable? A guy from India should find quickly his holiday data pack, and a guy from Sillicon Valley should find his pack as equally fast. It makes most sense to me to filter for COUNTRY STATE WHATEVER. Like a drill-down-search. Did I miss something? What would be the best data format to hold holiday information? A holiday has a start and end date and a name. That should be enough. Would I put all this stuff in thousands of XML files? How would you go about this? Any hint / help is highly welcome! Thanks to everyone!

• Accessing Python module fails although its package is imported

  - by codethief

  Hey Stackers! :) My Django project's directory hierarchy looks like this: + pybsd |---+ devices |---+ templates |---+ views |---+ interaction |---- __init__.py |---- geraete.py |---- geraetemodelle.py |---- geraetegruppen.py |---- __init__.py |---- ajax.py |---- html.py |---- misc.py |---- __init__.py |---- urls.py |---- __init__.py |---- urls.py (Please excuse the German names. I preferred not to replace them here since it would add yet another possible error source when trying out the solutions you'll hopefully suggest and answering your questions.) Every request to http://URL/devices/.* is dispatched to the urls.py file living in /devices: # ... from views import html, ajax, misc, interaction urlpatterns = patterns('', # ... (r'^ajax/update/(?P<table>[a-z_]+)$', ajax.update), (r'^ajax/delete/(?P<table>[a-z_]+)$', ajax.delete), (r'^ajax/select_options/(?P<table>[a-z_]+)$', ajax.select_options), (r'^interaction/geraete/info/(?P<geraet>\d+)$', interaction.geraete.info), (r'^interaction/geraete/delete/(?P<geraet>\d+)?$', interaction.geraete.delete), (r'^interaction/geraetemodelle/delete/(?P<geraetemodell>\d+)?$', interaction.geraetemodelle.delete), (r'^interaction/geraetegruppen/delete/(?P<geraetegruppe>\d+)?$', interaction.geraetegruppen.delete), # ... ) All URL definitions work except for those referencing the interaction package. I'm constantly getting the following error: File "/home/simon/projekte/pybsd/../pybsd/devices/urls.py", line 33, in `<module>` (r'^interaction/geraete/info/(?P<geraet>\d+)$', interaction.geraete.info), AttributeError: 'module' object has no attribute 'geraete' I double-checked that the __init__.py files don't contain anything. Maybe you've already found the (Python- or Django-related?) mistake I made and am apparently unable to see. If not, read on. In any case, thanks for reading this long post! Isolating the problem 1st test It works if I provide the view functions as strings: (r'^interaction/geraete/info/(?P<geraet>\d+)$', 'devices.views.interaction.geraete.info'), (r'^interaction/geraete/delete/(?P<geraet>\d+)?$', 'devices.views.interaction.geraete.delete'), (r'^interaction/geraetemodelle/delete/(?P<geraetemodell>\d+)?$', 'devices.views.interaction.geraetemodelle.delete'), (r'^interaction/geraetegruppen/delete/(?P<geraetegruppe>\d+)?$', 'devices.views.interaction.geraetegruppen.delete'), ... or add yet another line to the imports: from views.interaction import geraete, geraetemodelle, geraetegruppen Using from views.interaction import *, however, doesn't work either and results in the same error message. 2nd test I created a file test.py in /devices: from views import interaction print dir(interaction) Output: simon@bsd-simon:~/projekte/pybsd/devices$ python test.py ['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__'] Again, no sign of the modules I created in the interaction package (geraete.py, geraetemodelle.py, geraetegruppen.py). Unlike in urls.py, trying from view.interaction import geraete, geraetegruppen, geraetemodelle in test.py results in ImportError: No module named view.interaction this time. 3rd test I started the Django shell: $ python manage.py shell >>> import devices.views.interaction.geraete >>> dir(devices.views.interaction.geraete) ['Abteilung', 'Auftrag', 'Auftragsvorlage', 'Geraet', 'Geraetegruppe', 'Geraetemodell', 'HttpResponse', 'HttpResponseBadRequest', 'HttpResponseRedirect', 'Raum', 'Standort', '__builtins__', '__doc__', '__file__', '__name__', '__package__', 'delete', 'info', 'models', 'move', 'render_to_response'] >>> $ python manage.py shell >>> from devices.views.interaction import geraete >>> dir(geraete) ['Abteilung', 'Auftrag', 'Auftragsvorlage', 'Geraet', 'Geraetegruppe', 'Geraetemodell', 'HttpResponse', 'HttpResponseBadRequest', 'HttpResponseRedirect', 'Raum', 'Standort', '__builtins__', '__doc__', '__file__', '__name__', '__package__', 'delete', 'info', 'models', 'move', 'render_to_response'] >>> $ python manage.py shell >>> import devices.views.interaction >>> devices.views.interaction.geraete Traceback (most recent call last): File "<console>", line 1, in <module> AttributeError: 'module' object has no attribute 'geraete' >>> dir(devices.views.interaction) ['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__']

• jQuery dialog box, php form.

  - by tony noriega

  i have a dialog box that opens on pageload for a site. script type="text/javascript"> $(function() { $('#dialog-message').dialog({ modal: 'true', width: '400' }); }); </script> this pulls up an include: <div id="dialog-message" title="Free Jiu Jitsu Session at Alliance"> <!--#include virtual="/includes/guest.php" --> guest.php has a very small form that is processed by the page itself: <?php $dbh=mysql_connect //login stuff here if (isset($_POST['submit'])) { if (!$_POST['name'] | !$_POST['email']) { echo"<div class='error'>Error<br />Please provide your Name and Email Address so we may properly contact you.</div>"; } else { $age = $_POST['age']; $name = $_POST['name']; $gender = $_POST['gender']; $email = $_POST['email']; $phone = $_POST['phone']; $comments = $_POST['comments']; $query = "INSERT INTO table here (age,name,gender,email,phone,comments) VALUES ('$age','$name','$gender','$email','$phone','$comments')"; mysql_query($query); mysql_close(); $yoursite = "my site here"; $youremail = $email; $subject = "Website Guest Contact Us Form"; $message = "message here"; $email2 = "send to email address"; mail($email2, $subject, $message, "From: $email"); echo"<div class='thankyou'>Thank you for contacting us,<br /> we will respond as soon as we can.</div>"; } } ?> <form id="contact_us" class="guest" method="post" action="/guest.php" > <fieldset> <legend>Personal Info</legend> <label for="name" class="guest">Name:</label> <input type="text" name="name" id="name" value="" /><br> <label for="phone" class="guest">Phone:</label> <input type="text" name="phone" id="phone" value="" /><br> <label for="email" class="guest">Email Address:</label> <input type="text" name="email" id="email" value="" /><br> <label for="age" class="guest">Age:</label> <input type="text" name="age" id="age" value="" size="2" /><br> <label for="gender" class="guest">Sex:</label> <input type="radio" name="gender" value="male" /> Male <input type="radio" name="gender" value="female" /> Female<br /> </fieldset> <fieldset> <legend>Comments</legend> <label for="comments" class="guest">Comments / Questions:</label> <textarea id="comments" name="comments" rows="4" cols="22"></textarea><br> <input type="submit" value="Submit" name="submit" /> <input type="Reset" value="Reset" /> </fieldset> </form> Problem is, that the path of the form action does not work, becasue this dialog box is on the index.html page of the site, and if i put the absolute path, it doesnt process... i have this functioning on another contact us page, so i know it works, but wit the dialog box, it seems to have stumped me... what should i do?

• Asp.net MVC/Silverlight and Sharepoint 2010 integration

  - by Robert Koritnik

  Just a sidenote: I'm not sure whether I should post this to serverfault as well, because some MOSS admin may have some info for me as well? Additional note 1: I've found this document (Asp.net MVC 2 & Sharepoint integration) if anybody with sufficient expirience is willing to comment on its content whether this can be used in my described scenario or not. Additional note 2: I've discovered (later) that Silverlight is supported in Sharepoint 2010 so I'm considering it as well. So if anyone would comment on silverlight integration as well. A bit of explanation first (without Asp.net MVC/Silverlight) Is it possible to integrate the two? Is it possible to write an application that would share at least credential information with MOSS? I have to write a MOSS application that has to do with these technologies: MOSS 2010 Personal client certificates authentication (most probably on USB keys) Active Directory Federation Services Separate SQL DB that would serve application specific data (separate as not being part of MOSS DB) How should it work? Users should authenticate using personal certificates into MOSS 2010 There would be a certain part of MOSS that would be related to my custom application This application should only authorize certain users via AD FS - I guess these users should have a certain security claim attached to them This application should manage users (that have access to this app) with additional (app specific) security claims related to this application (as additional application level authorization rights for individual application parts) This application should use custom SQL 2008 DB heavily with its own data This application should have the possibility to integrate with external systems as well (Exchange for instance to inject calendar entries, ERP systems etc) This application should be able to export its data (from its DB) to files. I don't know if it's possible, but it would be nice if the app could add these files to MOSS and attach authorization info to them so only users with sufficient rights would be able to view/open these files. Why Asp.net MVC/Silverlight then? I'm very well versed in Asp.net MVC (also with the latest version) and I haven't done anything on Sharepoint since version 2003 (which doesn't do me no good or prepare me for the latest version in any way shape or form). This project will most probably be a death march project so I would rather write my application as a UI rich Asp.net MVC application and somehow integrate it into MOSS. But not only via a link, because I would like to at least share credentials, so users wouldn't need to re-login when accessing my app. Using Asp.net MVC I would at least have the possibility to finish on time or be less death marching. Is this at all possible? I haven't done any serious project using SIlverlight, but I will sooner or later have to. So I'm also considering a jump into it at this moment, because it still might make this application development easier than strict Sharepoint 2010. Questions Is it possible to integrate Asp.net MVC/Silverlight into MOSS as described above? If integration is not possible, would it be possible to create a completely MOSS based application that would work as described? Which parts of MOSS 2010 should I use to accomplish what I need?

• NSMutableString leaks on append or replaceOccurrencesOfString

  - by John

  Hello Folks, I know similar questions have been asked time and time again but I ask that you please bear with me as I cannot seem to find an answer that helps. My application has leaks that are driving me out of my mind. Actually, they are not reported as leaks using Leaks, but my net bytes in ObjectAlloc goes up and up and up and never stops, eventually leading to a crash if it goes on long enough (not very long). The problem occurs with NSMutableStrings. I think there is either something fundamental I don't understand about them, or I am facing another problem that I am having difficulty tracking down but keeps hiding behind the NSMutableStrings. Specifically, I am noticing that whenever I append to or perform a replace on a NSMutableString, ObjectAlloc reports what appear to be mismatches in malloc/frees behind the scene when resizing the NSMutableString. I'm sorry to say this is the second time I'm facing this problem - the first time I messed around for hours and hours and finally the problem went away (magic!) but I don't really know why. When I look at the code below (and believe me, I've stared at it for hours) I cannot see the problem. I look at the code and think to myself that I should be fine because I'm releasing the only object for which I am responsible (aString) and that NSMutableString should be taking care of cleaning up after any resizing it does. In the second example, just so you know in case it helps, the string being passed in comes from an ASIHTTPRequest object (it's the responseString) and I don't do anything at all with it. It's being called simply like so ([self DoStuff2:[request responseString]]) and I don't free the request myself either (I'm using a ASINetworkQueue and I assume that the requests are destroyed for me (I tried and caused errors because the request was already being release somewhere else). Also, I know it shouldn't do anything, but I even tried wrapping the code in autorelease pools, which of course did nothing. I should mention that this code is being run inside of an NSOperation. I thought that perhaps I am experiencing problems because NSOperations should create an autorelease pool for themselves, but I've tried that to no avail. Not related to NSMutableString, but I find I also have similar problems using the NSString componentsSeparatedByString method. Sometimes the memory used by the array that gets the separated components is never released. Hmmm...strings in general seem to be somewhat problematic for me it seems. I would appreciate ANY help anyone can provide. If you require more info, I'll be glad to add it. I do promise you that I've struggled with this (and other problems) for weeks and every problem I encounter I research hard and long until I find a solution - this is not an idle request, but a true cry for help! I've written so much code and now I'm trying to seal some small leaks etc and I notice this problem. Honestly, I cannot believe how memory management in Objective C can stump me so at times...I've read Apple's memory mgmt docs many times and I thought I thoroughly understood it and I try to be diligent about releasing objects I own, but sometimes I find myself wondering if I truly understand...I would like to put this to bed once and make sure I understand all this fully - to have this sort of question/problem after writing thousands of lines of code is more than a little scary/embarrassing/annoying. So again, if anybody has any insight, I'd be grateful. Thanks for your time and efforts. -(void)DoStuff { NSString *aString [ [[NSString alloc] initWithFormat:@"text %@ more text", self.strVariable]; [self.someMutableStringVar replaceOccurrencesOfString:@"replace" withString:aString options:NSCaseInsensitiveSearch range:NSMakeRange(0, [self.someMutableStringVar length])]; [aString release]; } -(void)DoStuff2:(NSString *)aString { [self.someMutableStringVar appendString:aString]; }

• How do I use connect to DB2 with DBI and mod_perl?

  - by Matthew

  I'm having issues with getting DBI's IBM DB2 driver to work with mod_perl. My test script is: #!/usr/bin/perl use strict; use CGI; use Data::Dumper; use DBI; { my $q; my $dsn; my $username; my $password; my $sth; my $dbc; my $row; $q = CGI->new; print $q->header; print $q->start_html(); $dsn = "DBI:DB2:SAMPLE"; $username = "username"; $password = "password"; print "<pre>".$q->escapeHTML(Dumper(\%ENV))."</pre>"; $dbc = DBI->connect($dsn, $username, $password); $sth = $dbc->prepare("SELECT * FROM SOME_TABLE WHERE FIELD='SOMETHING'"); $sth->execute(); $row = $sth->fetchrow_hashref(); print "<pre>".$q->escapeHTML(Dumper($row))."</pre>"; print $q->end_html; } This script works as CGI but not under mod_perl. I get this error in apache's error log: DBD::DB2::dr connect warning: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /usr/lib/perl5/site_perl/5.8.8/Apache/DBI.pm line 190. DBI connect('SAMPLE','username',...) failed: [unixODBC][Driver Manager]Data source name not found, and no default driver specified at /data/www/perl/test.pl line 15 First of all, why is it using ODBC? The native DB2 driver is installed (hence it works as CGI). Running Apache 2.2.3, mod_perl 2.0.4 under RHEL5. This guy had the same problem as me: http://www.mail-archive.com/[email protected]/msg22909.html But I have no idea how he fixed it. What does mod_php4 have to do with mod_perl? Any help would be greatly appreciated, I'm having no luck with google. Update: As james2vegas pointed out, the problem has something to do with PHP: I disable PHP all together I get the a different error: Total Environment allocation failure! Did you set up your DB2 client environment? I believe this error is to do with environment variables not being set up correctly, namely DB2INSTANCE. However, I'm not able to turn off PHP to resolve this problem (I need it for some legacy applications). So I now have 2 questions: How can I fix the original issue without disabling PHP all together? How can I fix the environment issue? I've set DB2INSTANCE, DB2_PATH and SQLLIB variables correctly using SetEnv and PerlSetEnv in httpd.conf, but with no luck. Note: I've edited the code to determine if the problem was to do with Global Variable Persistence.

• JQuery SelectToUISlider Issues

  - by David Savage

  Hopefully this hasn't been asked before as just a slider question, but I couldn't find an answer when already browsing questions. So, here goes: I have a SelectToUISlider (http://www.filamentgroup.com/lab/update_jquery_ui_slider_from_a_select_element_now_with_aria_support/) which is basically a modified JQuery UI Slider, and I'm using a range value. So, I start with one handle at 60, and another at 100 (scale from 0 to 100). What I want to do is click a radio button so that the 100 changes to a 0, and be able to change back to 100. I have been unsuccessful at changing it via JQuery selectors/javascript. However, when changing the selects to move the handles, this works, but the range appears not to follow if the second handle (at 100) moves to 0 behind the first handle (at 60). I'm thinking I might have to destroy the slider and rebuild it with the second handle (that starts as 100) become the first handle at 0 in this scenario (although I've tried destroying it and it doesn't seem to respond to that either.) Here's what I've tried so far that doesn't work: <script type="text/javascript"> {literal} $(function(){ $('select').selectToUISlider({ labels: 10 }); }); function event_occurs(does) { if (does == 1) { $('.ui-slider').slider('option', 'values', [60,100]); } else { $('.ui-slider').slider('option', 'values', [0,60]); } } </script> <style type="text/css"> form {font-size: 62.5%; font-family:"Segoe UI","Helvetica Neue",Helvetica,Arial,sans-serif; } fieldset { border:0; margin: 1em; height: 12em;} label {font-weight: normal; float: left; margin-right: .5em; font-size: 1.1em;} select {margin-right: 1em; float: left;} .ui-slider {clear: both; top: 5em;} .ui-slider-tooltip {white-space: nowrap;} </style> {/literal} <form action="#"> <fieldset> <select name="valueA" id="my_estimate"> {section name="estimates" loop=101} <option value="{$smarty.section.estimates.index}"{if $smarty.section.estimates.index == 60} selected{/if}>{$smarty.section.estimates.index}</option> {/section} </select> <select name="valueB" id="payout"> {section name="estimates" loop=101} <option value="{$smarty.section.estimates.index}"{if $smarty.section.estimates.index == 100} selected{/if}>{$smarty.section.estimates.index}</option> {/section} </select> </fieldset> </form> <input type="radio" onclick="event_occurs(1)" name="Event" checked="checked"> Event Occurs<br /> <input type="radio" onclick="event_occurs(0)" name="Event"> Event Does Not Occur As it is now, nothing happens when clicking the radio buttons, but I'm also not getting any Javascript errors. After I get this working, I would also like to find some way to disable one of the handles through changing the slider property. Ie leave the handle where its at but not allow it to be dragged. Any help is greatly appreciated.

• css & horizontal scrolling

  - by zen

  One of my most favorite websites is that of the Oxford Hotel in Romania. I like the simplicity of the site and how it flows. I am trying to create a similar scrolling effect using jquery and I've been somewhat successful to a point. My trouble is with css... I am not a wizard in that department. Anyway,...my questions! 1. How can I first make sure that the ".box" class will be in the center of the page when the corresponding link is clicked? Right now it positions itself on the left. 2. Then, how can I tweak this code so that the user only can see the width of the screen and not the browser scroller/the rest of my ".box" divs? Refer to the oxford link if you need to see an example of what I'd like to achieve. This is a portion of my current CSS. body { background: #f2f2f2; text-align:left; color:#666; font-size:14px; font-family:georgia, 'time new romans', serif; margin:0 auto; padding:0; } #menu { background: #333333; position: fixed; top: 0px; left: 0; border: 1px solid #000; clear: both; float: left; font-family: helvetica, sans-serif; font-size: 18px; text-transform: uppercase; margin: 0; padding: 18px; z-index: 500; filter: alpha(opacity=75); opacity: .75; } #menu ul{ list-style-type: none; margin: 0; padding: 0; } #menu ul li{ list-style-type: none; color: #777; display: inline; margin: 0; padding: 0 10px 0 10px; } #menu ul li a{ text-decoration: none; list-style-type: none; color: #777; display: inline; margin: 0; padding: 0; } #menu ul li a:hover{ text-decoration: none; list-style-type: none; color: #fff; display: inline; margin: 0; padding: 0; } #container { position: absolute; top: 120px; width: 70000px; margin: 0; padding: 0; } .box { background: white; border: 3px dashed #f2f2f2; width: 600px; float: left; font-size: 10px; line-height: 15px; margin: 0; padding: 5px 30px 30px 30px; }

• Use JAXB unmarshalling in Weblogic Server

  - by Leo

  Especifications: - Server: Weblogic 9.2 fixed by customer. - Webservices defined by wsdl and xsd files fixed by customer; not modifications allowed. Hi, In the project we need to develope a mail system. This must do common work with the webservice. We create a Bean who recieves an auto-generated class from non-root xsd element (not wsdl); this bean do this common work. The mail system recieves a xml with elements defined in xsd file and we need to drop this elements info to wsdlc generated classes. With this objects we can use this common bean. Is not possible to redirect the mail request to the webservice. We've looking for the code to do this with WL9.2 resources but we don't found anything. At the moment we've tried to use JAXB for this unmarshalling: JAXBContext c = JAXBContext.newInstance(new Class[]{WasteDCSType.class}); Unmarshaller u = c.createUnmarshaller(); WasteDCSType w = u.unmarshal(waste, WasteDCSType.class).getValue(); waste variable is an DOM Element object. It isn't the root element 'cause the root isn't included in XSD First we needed to add no-arg constructor in some autogenerated classes. No problem, we solved this and finally we unmarshalled the xml without error Exceptions. But we had problems with the attributes. The unmarshalling didn't set attributes; none of them in any class, not simple attributes, not large or short enumeration attributes. No problem with xml elements of any type. We can't create the unmarshaller from "context string" (the package name) 'cause not ObjectFactory has been create by wsldc. If we set the schema no element descriptions are founded and unmarshall crashes. This is the build content: <taskdef name="jwsc" classname="weblogic.wsee.tools.anttasks.JwscTask" /> <taskdef name="wsdlc" classname="weblogic.wsee.tools.anttasks.WsdlcTask"/> <target name="generate-from-wsdl"> <wsdlc srcWsdl="${src.dir}/wsdls/e3s-environmentalMasterData.wsdl" destJwsDir="${src.dir}/webservices" destImplDir="${src.dir}/webservices" packageName="org.arc.eterws.generated" /> <wsdlc srcWsdl="${src.dir}/wsdls/e3s-waste.wsdl" destJwsDir="${src.dir}/webservices" destImplDir="${src.dir}/webservices" packageName="org.arc.eterws.generated" /> </target> <target name="webservices" description=""> <jwsc srcdir="${src.dir}/webservices" destdir="${dest.dir}" classpathref="wspath"> <module contextPath="E3S" name="webservices"> <jws file="org/arc/eterws/impl/IE3SEnvironmentalMasterDataImpl.java" compiledWsdl="${src.dir}/webservices/e3s-environmentalMasterData_wsdl.jar"/> <jws file="org/arc/eterws/impl/Ie3SWasteImpl.java" compiledWsdl="${src.dir}/webservices/e3s-waste_wsdl.jar"/> <descriptor file="${src.dir}/webservices/META-INF/web.xml"/> </module> </jwsc> </target> My questions are: How Weblogic "unmarshall" the xml with the JAX-RPC tech and can we do the same with a xsd element? How can we do this if yes? If not, Exists any not complex solution to this problem? If not, must we use XMLBean tech. or regenerate the XSD with JAXB tech.? What is the best solution? NOTE: There are not one single xsd but a complex xsd structure in fact.

• Image displays when clicked with multiple radio button groups

  - by Jean

  I'm creating a form that has seven different selection groups, most with radio buttons (ie: buns, cheese), a couple with check boxes (toppings). I need jQuery to differentiate the groups and display images when clicked.

• Managing highly repetitive code and documentation in Java

  - by polygenelubricants

  Highly repetitive code is generally a bad thing, and there are design patterns that can help minimize this. However, sometimes it's simply inevitable due to the constraints of the language itself. Take the following example from java.util.Arrays: /** * Assigns the specified long value to each element of the specified * range of the specified array of longs. The range to be filled * extends from index <tt>fromIndex</tt>, inclusive, to index * <tt>toIndex</tt>, exclusive. (If <tt>fromIndex==toIndex</tt>, the * range to be filled is empty.) * * @param a the array to be filled * @param fromIndex the index of the first element (inclusive) to be * filled with the specified value * @param toIndex the index of the last element (exclusive) to be * filled with the specified value * @param val the value to be stored in all elements of the array * @throws IllegalArgumentException if <tt>fromIndex &gt; toIndex</tt> * @throws ArrayIndexOutOfBoundsException if <tt>fromIndex &lt; 0</tt> or * <tt>toIndex &gt; a.length</tt> */ public static void fill(long[] a, int fromIndex, int toIndex, long val) { rangeCheck(a.length, fromIndex, toIndex); for (int i=fromIndex; i<toIndex; i++) a[i] = val; } The above snippet appears in the source code 8 times, with very little variation in the documentation/method signature but exactly the same method body, one for each of the root array types int[], short[], char[], byte[], boolean[], double[], float[], and Object[]. I believe that unless one resorts to reflection (which is an entirely different subject in itself), this repetition is inevitable. I understand that as a utility class, such high concentration of repetitive Java code is highly atypical, but even with the best practice, repetition does happen! Refactoring doesn't always work because it's not always possible (the obvious case is when the repetition is in the documentation). Obviously maintaining this source code is a nightmare. A slight typo in the documentation, or a minor bug in the implementation, is multiplied by however many repetitions was made. In fact, the best example happens to involve this exact class: Google Research Blog - Extra, Extra - Read All About It: Nearly All Binary Searches and Mergesorts are Broken (by Joshua Bloch, Software Engineer) The bug is a surprisingly subtle one, occurring in what many thought to be just a simple and straightforward algorithm. // int mid =(low + high) / 2; // the bug int mid = (low + high) >>> 1; // the fix The above line appears 11 times in the source code! So my questions are: How are these kinds of repetitive Java code/documentation handled in practice? How are they developed, maintained, and tested? Do you start with "the original", and make it as mature as possible, and then copy and paste as necessary and hope you didn't make a mistake? And if you did make a mistake in the original, then just fix it everywhere, unless you're comfortable with deleting the copies and repeating the whole replication process? And you apply this same process for the testing code as well? Would Java benefit from some sort of limited-use source code preprocessing for this kind of thing? Perhaps Sun has their own preprocessor to help write, maintain, document and test these kind of repetitive library code? A comment requested another example, so I pulled this one from Google Collections: com.google.common.base.Predicates lines 276-310 (AndPredicate) vs lines 312-346 (OrPredicate). The source for these two classes are identical, except for: AndPredicate vs OrPredicate (each appears 5 times in its class) "And(" vs Or(" (in the respective toString() methods) #and vs #or (in the @see Javadoc comments) true vs false (in apply; ! can be rewritten out of the expression) -1 /* all bits on */ vs 0 /* all bits off */ in hashCode() &= vs |= in hashCode()

• Should we develop a custom membership provider in this case?

  - by Allen

  I'll be adding a bounty to this, probably 200, more if you guys think its appropriate. I wont accept an answer until I can add a bounty so feel free to go ahead and answer now Summary Long story short, we've been tasked with gutting the authentication and authorization parts of a fairly old and bloated asp.net application that previously had all of these components written from scratch. Since our application isn't a typical one, and none of us have experience in asp.net's built in membership provider stuff, we're not sure if we should roll our own authentication and authorization again or if we should try to work within the asp.net membership provider mindset and develop our own membership provider. Our Application We have a fairly old asp.net application that gets installed at customer locations to service clients on a LAN. Admins create users (users do not sign up) and depending on the install, we may have the software integrated with LDAP. Currently, the LDAP integration bulk-imports the users to our database and when they login, it authenticates against LDAP so we dont have to manage their passwords. Nothing amazing there. Admins can assign users to 1 group and they can change the authorization of that group to manage access to various parts of the software. Groups are maintained by Admins (web based UI) and as said earlier, granted / denied permissions to certain functionality within the application. All this was completely written from the ground up without using any of the built in .net authorization or authentication. We literally have IsLoggedIn() methods that check for login and redirect to our login page if they aren't. Our Rewrite We've been tasked to integrate more tightly with LDAP, they want us to tie groups in our application to groups (or whatever types of containers that LDAP uses) in LDAP so that when a customer opt's to use our LDAP integration, they dont have to manage their users in LDAP AND in our application. The new way, they will simply create users in LDAP, add them to Groups in LDAP and our application will see that they belong to the appropriate LDAP group and authenticate and authorize them. In addition, we've been granted the go ahead to completely rip out the User authentication and authorization code and completely re-do it. Our Problem The problem is that none of us have any experience with asp.net membership provider functionality. The little bit of exposure I have to it makes me worry that it was not intended to be used for an application such as ours. Though, developing our own ASP.NET Membership Provider and Role Manager sounds like it would be a great experience and most likely the appropriate thing to do. Basically, I'm looking for advice, should we be using the ASP.NET Membership provider & Role Management API or should we continue to roll our own? I know this decision will be influenced by our requirements so I'm going over them below Our Requirements Just a quick n dirty list Maintain the ability to have a db of users and authenticate them and give admins (only, not users) the ability to CRUD users Allow the site to integrate with LDAP, when this is chosen, they don't want any users stored in the DB, only the relationship between Groups as they exist in our app / db and the Groups/Containers as they exist in LDAP. .net 3.5 is being used (mix of asp.net webforms and asp.net mvc) Has to work in ASP.NET and ASP.NET MVC (shouldn't be a problem I'm guessing) This can't be user centric, administrators need to be the only ones that CRUD (or import via ldap) users and groups We have to be able to Auth via LDAP when its configured to do so I always try to monitor my questions closely so feel free to ask for more info. Also, as a general summary of what I'm looking for in an answer is just. "You should/shouldn't use xyz, here's why". Links regarding asp.net membership provider and role management stuff are very welcome, most of the stuff I'm finding is 5+ years old. Edit: Added some stuff to "Our Rewrite"

• How do I solve an unresolved external when using C++ Builder packages?

  - by David M

  I'm experimenting with reconfiguring my application to make heaving use of packages. Both I and another developer running a similar experiment are running into a bit of trouble when linking using several different packages. We're probably both doing something wrong, but goodness knows what :) The situation is this: The first package, PackageA.bpl, contains C++ class FooA. The class is declared with the PACKAGE directive. The second package, PackageB.bpl, contains a class inheriting from FooA, called FooB. It includes FooB.h, and the package is built using runtime packages, and links to PackageA by adding a reference to PackageA.bpi. When building PackageB, it compiles fine but linking fails with a number of unresolved externals, the first few of which are: [ILINK32 Error] Error: Unresolved external '__tpdsc__ FooA' referenced from C:\blah\FooB.OBJ [ILINK32 Error] Error: Unresolved external 'FooA::' referenced from C:\blah\FooB.OBJ [ILINK32 Error] Error: Unresolved external '__fastcall FooA::~FooA()' referenced from blah\FooB.OBJ etc. Running TDump on PackageA.bpl shows: Exports from PackageA.bpl 14 exported name(s), 14 export addresse(s). Ordinal base is 1. Sorted by Name: RVA Ord. Hint Name -------- ---- ---- ---- 00002A0C 8 0000 __tpdsc__ FooA 00002AD8 10 0001 __linkproc__ FooA::Finalize 00002AC8 9 0002 __linkproc__ FooA::Initialize 00002E4C 12 0003 __linkproc__ PackageA::Finalize 00002E3C 11 0004 __linkproc__ PackageA::Initialize 00006510 14 0007 FooA:: 00002860 5 0008 FooA::FooA(FooA&) 000027E4 4 0009 FooA::FooA() 00002770 3 000A __fastcall FooA::~FooA() 000028DC 6 000B __fastcall FooA::Method1() const 000028F4 7 000C __fastcall FooA::Method2() const 00001375 2 000D Finalize 00001368 1 000E Initialize 0000610C 13 000F ___CPPdebugHook So the class definitely seems to be exported and available to link. I can see entries for the specific things ILink32 says it's looking for and not finding. Running TDump on the BPI file shows similar entries. Other info The class does descend from TObject, though originally before refactoring into packages it was a normal C++ class. (More detail below. It seems "safer" using VCL-style classes when trying to solve problems with a very Delphi-ish thing like this anyway. Changing this only changes the order of unresolved externals to first not find Method1 and Method2, then others.) Declaration for FooA: class PACKAGE FooA: public TObject { public: FooA(); virtual __fastcall ~FooA(); FooA(const FooA&); virtual __fastcall long Method1() const; virtual __fastcall long Method2() const; }; and FooB: class FooB: public FooA { public: FooB(); virtual __fastcall ~FooB(); ... other methods... }; All methods definitely are implemented in the .cpp files, so it's not not finding them because they don't exist! The .cpp files also contain #pragma package(smart_init) near the top, under the includes. Questions that might help... Are packages reliable using C++, or are they only useable with Delphi code? Is linking to the first package by adding a reference to its BPI correct - is that how you're supposed to do it? I could use a LIB but it seems to make the second package much larger, and I suspect it's statically linking in the contents of the first. Can we use the PACKAGE directive only on TObject-derived classes? There is no compiler warning using it on standard C++ classes. Is splitting code into packages the best way to achieve the goal of isolating code and communicating through defined layers / interfaces? I've been investigating this path because it seems to be the C++Builder / Delphi Way, and if it worked it looks attractive. But are there better alternatives? I'm very new to using packages and have only known about them through using components before. Any general words of advice would be great! We're using C++Builder 2010. I've fabricated the class and method names in the above code examples, but other than that the details are exactly what we're seeing. Cheers, David

• Is SQL Server DRI (ON DELETE CASCADE) slow?

  - by Aaronaught

  I've been analyzing a recurring "bug report" (perf issue) in one of our systems related to a particularly slow delete operation. Long story short: It seems that the CASCADE DELETE keys were largely responsible, and I'd like to know (a) if this makes sense, and (b) why it's the case. We have a schema of, let's say, widgets, those being at the root of a large graph of related tables and related-to-related tables and so on. To be perfectly clear, deleting from this table is actively discouraged; it is the "nuclear option" and users are under no illusions to the contrary. Nevertheless, it sometimes just has to be done. The schema looks something like this: Widgets | +--- Anvils (1:1) | | | +--- AnvilTestData (1:N) | +--- WidgetHistory (1:N) | +--- WidgetHistoryDetails (1:N) Nothing too scary, really. A Widget can be different types, an Anvil is a special type, so that relationship is 1:1 (or more accurately 1:0..1). Then there's a large amount of data - perhaps thousands of rows of AnvilTestData per Anvil collected over time, dealing with hardness, corrosion, exact weight, hammer compatibility, usability issues, and impact tests with cartoon heads. Then every Widget has a long, boring history of various types of transactions - production, inventory moves, sales, defect investigations, RMAs, repairs, customer complaints, etc. There might be 10-20k details for a single widget, or none at all, depending on its age. So, unsurprisingly, there's a CASCADE DELETE relationship at every level here. If a Widget needs to be deleted, it means something's gone terribly wrong and we need to erase any records of that widget ever existing, including its history, test data, etc. Again, nuclear option. Relations are all indexed, statistics are up to date. Normal queries are fast. The system tends to hum along pretty smoothly for everything except deletes. Getting to the point here, finally, for various reasons we only allow deleting one widget at a time, so a delete statement would look like this: DELETE FROM Widgets WHERE WidgetID = @WidgetID Pretty simple, innocuous looking delete... that takes over 2 minutes to run, for a widget with no data! After slogging through execution plans I was finally able to pick out the AnvilTestData and WidgetHistoryDetails deletes as the sub-operations with the highest cost. So I experimented with turning off the CASCADE (but keeping the actual FK, just setting it to NO ACTION) and rewriting the script as something very much like the following: DECLARE @AnvilID int SELECT @AnvilID = AnvilID FROM Anvils WHERE WidgetID = @WidgetID DELETE FROM AnvilTestData WHERE AnvilID = @AnvilID DELETE FROM WidgetHistory WHERE HistoryID IN ( SELECT HistoryID FROM WidgetHistory WHERE WidgetID = @WidgetID) DELETE FROM Widgets WHERE WidgetID = @WidgetID Both of these "optimizations" resulted in significant speedups, each one shaving nearly a full minute off the execution time, so that the original 2-minute deletion now takes about 5-10 seconds - at least for new widgets, without much history or test data. Just to be absolutely clear, there is still a CASCADE from WidgetHistory to WidgetHistoryDetails, where the fanout is highest, I only removed the one originating from Widgets. Further "flattening" of the cascade relationships resulted in progressively less dramatic but still noticeable speedups, to the point where deleting a new widget was almost instantaneous once all of the cascade deletes to larger tables were removed and replaced with explicit deletes. I'm using DBCC DROPCLEANBUFFERS and DBCC FREEPROCCACHE before each test. I've disabled all triggers that might be causing further slowdowns (although those would show up in the execution plan anyway). And I'm testing against older widgets, too, and noticing a significant speedup there as well; deletes that used to take 5 minutes now take 20-40 seconds. Now I'm an ardent supporter of the "SELECT ain't broken" philosophy, but there just doesn't seem to be any logical explanation for this behaviour other than crushing, mind-boggling inefficiency of the CASCADE DELETE relationships. So, my questions are: Is this a known issue with DRI in SQL Server? (I couldn't seem to find any references to this sort of thing on Google or here in SO; I suspect the answer is no.) If not, is there another explanation for the behaviour I'm seeing? If it is a known issue, why is it an issue, and are there better workarounds I could be using?

• boost::function & boost::lambda again

  - by John Dibling

  Follow-up to post: http://stackoverflow.com/questions/2978096/using-width-precision-specifiers-with-boostformat I'm trying to use boost::function to create a function that uses lambdas to format a string with boost::format. Ultimately what I'm trying to achieve is using width & precision specifiers for strings with format. boost::format does not support the use of the * width & precision specifiers, as indicated in the docs: Width or precision set to asterisk (*) are used by printf to read this field from an argument. e.g. printf("%1$d:%2$.*3$d:%4$.*3$d\n", hour, min, precision, sec); This class does not support this mechanism for now. so such precision or width fields are quietly ignored by the parsing. so I'm trying to find other ways to accomplish the same goal. Here is what I have so far, which isn't working: #include <string> #include <boost\function.hpp> #include <boost\lambda\lambda.hpp> #include <iostream> #include <boost\format.hpp> #include <iomanip> #include <boost\bind.hpp> int main() { using namespace boost::lambda; using namespace std; boost::function<std::string(int, std::string)> f = (boost::format("%s") % boost::io::group(setw(_1*2), setprecision(_2*2), _3)).str(); std::string s = (boost::format("%s") % f(15, "Hello")).str(); return 0; } This generates many compiler errors: 1>------ Build started: Project: hacks, Configuration: Debug x64 ------ 1>Compiling... 1>main.cpp 1>.\main.cpp(15) : error C2872: '_1' : ambiguous symbol 1> could be 'D:\Program Files (x86)\boost\boost_1_42\boost/lambda/core.hpp(69) : boost::lambda::placeholder1_type &boost::lambda::`anonymous-namespace'::_1' 1> or 'D:\Program Files (x86)\boost\boost_1_42\boost/bind/placeholders.hpp(43) : boost::arg<I> `anonymous-namespace'::_1' 1> with 1> [ 1> I=1 1> ] 1>.\main.cpp(15) : error C2664: 'std::setw' : cannot convert parameter 1 from 'boost::lambda::placeholder1_type' to 'std::streamsize' 1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called 1>.\main.cpp(15) : error C2872: '_2' : ambiguous symbol 1> could be 'D:\Program Files (x86)\boost\boost_1_42\boost/lambda/core.hpp(70) : boost::lambda::placeholder2_type &boost::lambda::`anonymous-namespace'::_2' 1> or 'D:\Program Files (x86)\boost\boost_1_42\boost/bind/placeholders.hpp(44) : boost::arg<I> `anonymous-namespace'::_2' 1> with 1> [ 1> I=2 1> ] 1>.\main.cpp(15) : error C2664: 'std::setprecision' : cannot convert parameter 1 from 'boost::lambda::placeholder2_type' to 'std::streamsize' 1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called 1>.\main.cpp(15) : error C2872: '_3' : ambiguous symbol 1> could be 'D:\Program Files (x86)\boost\boost_1_42\boost/lambda/core.hpp(71) : boost::lambda::placeholder3_type &boost::lambda::`anonymous-namespace'::_3' 1> or 'D:\Program Files (x86)\boost\boost_1_42\boost/bind/placeholders.hpp(45) : boost::arg<I> `anonymous-namespace'::_3' 1> with 1> [ 1> I=3 1> ] 1>.\main.cpp(15) : error C2660: 'boost::io::group' : function does not take 3 arguments 1>.\main.cpp(15) : error C2228: left of '.str' must have class/struct/union 1>Build log was saved at "file://c:\Users\john\Documents\Visual Studio 2005\Projects\hacks\x64\Debug\BuildLog.htm" 1>hacks - 7 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== My fundamental understanding of boost's lambdas and functions is probably lacking.

• LINQ Generic Query with inherited base class?

  - by sah302

  I am trying to write some generic LINQ queries for my entities, but am having issue doing the more complex things. Right now I am using an EntityDao class that has all my generics and each of my object class Daos (such as Accomplishments Dao) inherit it, am example: using LCFVB.ObjectsNS; using LCFVB.EntityNS; namespace AccomplishmentNS { public class AccomplishmentDao : EntityDao<Accomplishment>{} } Now my entityDao has the following code: using LCFVB.ObjectsNS; using LCFVB.LinqDataContextNS; namespace EntityNS { public abstract class EntityDao<ImplementationType> where ImplementationType : Entity { public ImplementationType getOneByValueOfProperty(string getProperty, object getValue) { ImplementationType entity = null; if (getProperty != null && getValue != null) { //Nhibernate Example: //ImplementationType entity = default(ImplementationType); //entity = Me.session.CreateCriteria(Of ImplementationType)().Add(Expression.Eq(getProperty, getValue)).UniqueResult(Of InterfaceType)() LCFDataContext lcfdatacontext = new LCFDataContext(); //Generic LINQ Query Here lcfdatacontext.GetTable<ImplementationType>(); lcfdatacontext.SubmitChanges(); lcfdatacontext.Dispose(); } return entity; } public bool insertRow(ImplementationType entity) { if (entity != null) { //Nhibernate Example: //Me.session.Save(entity, entity.Id) //Me.session.Flush() LCFDataContext lcfdatacontext = new LCFDataContext(); //Generic LINQ Query Here lcfdatacontext.GetTable<ImplementationType>().InsertOnSubmit(entity); lcfdatacontext.SubmitChanges(); lcfdatacontext.Dispose(); return true; } else { return false; } } } }             I have gotten the insertRow function working, however I am not even sure how to go about doing getOnebyValueOfProperty, the closest thing I could find on this site was: http://stackoverflow.com/questions/2157560/generic-linq-to-sql-query How can I pass in the column name and the value I am checking against generically using my current set-up? It seems like from that link it's impossible since using a where predicate because entity class doesn't know what any of the properties are until I pass them in. Lastly, I need some way of setting a new object as the return type set to the implementation type, in nhibernate (what I am trying to convert from) it was simply this line that did it: ImplentationType entity = default(ImplentationType); However default is an nhibernate command, how would I do this for LINQ? EDIT: getOne doesn't seem to work even when just going off the base class (this is a partial class of the auto generated LINQ classes). I even removed the generics. I tried: namespace ObjectsNS { public partial class Accomplishment { public Accomplishment getOneByWhereClause(Expression<Action<Accomplishment, bool>> singleOrDefaultClause) { Accomplishment entity = new Accomplishment(); if (singleOrDefaultClause != null) { LCFDataContext lcfdatacontext = new LCFDataContext(); //Generic LINQ Query Here entity = lcfdatacontext.Accomplishments.SingleOrDefault(singleOrDefaultClause); lcfdatacontext.Dispose(); } return entity; } } } Get the following error: Error 1 Overload resolution failed because no accessible 'SingleOrDefault' can be called with these arguments: Extension method 'Public Function SingleOrDefault(predicate As System.Linq.Expressions.Expression(Of System.Func(Of Accomplishment, Boolean))) As Accomplishment' defined in 'System.Linq.Queryable': Value of type 'System.Action(Of System.Func(Of LCFVB.ObjectsNS.Accomplishment, Boolean))' cannot be converted to 'System.Linq.Expressions.Expression(Of System.Func(Of LCFVB.ObjectsNS.Accomplishment, Boolean))'. Extension method 'Public Function SingleOrDefault(predicate As System.Func(Of Accomplishment, Boolean)) As Accomplishment' defined in 'System.Linq.Enumerable': Value of type 'System.Action(Of System.Func(Of LCFVB.ObjectsNS.Accomplishment, Boolean))' cannot be converted to 'System.Func(Of LCFVB.ObjectsNS.Accomplishment, Boolean)'. 14 LCF Okay no problem I changed: public Accomplishment getOneByWhereClause(Expression<Action<Accomplishment, bool>> singleOrDefaultClause) to: public Accomplishment getOneByWhereClause(Expression<Func<Accomplishment, bool>> singleOrDefaultClause) Error goes away. Alright, but now when I try to call the method via: Accomplishment accomplishment = new Accomplishment(); var result = accomplishment.getOneByWhereClause(x=>x.Id = 4) It doesn't work it says x is not declared. I also tried getOne, and various other Expression =(

• Allocation algorithm help, using Python.

  - by Az

  Hi there, I've been working on this general allocation algorithm for students. The pseudocode for it (a Python implementation) is: for a student in a dictionary of students: for student's preference in a set of preferences (ordered from 1 to 10): let temp_project be the first preferred project check if temp_project is available if so, allocate it to them and make the project UNavailable to others Quite simply this will try to allocate projects by starting from their most preferred. The way it works, out of a set of say 100 projects, you list 10 you would want to do. So the 10th project wouldn't be the "least preferred overall" but rather the least preferred in their chosen set, which isn't so bad. Obviously if it can't allocate a project, a student just reverts to the base case which is an allocation of None, with a rank of 11. What I'm doing is calculating the allocation "quality" based on a weighted sum of the ranks. So the lower the numbers (i.e. more highly preferred projects), the better the allocation quality (i.e. more students have highly preferred projects). That's basically what I've currently got. Simple and it works. Now I'm working on this algorithm that tries to minimise the allocation weight locally (this pseudocode is a bit messy, sorry). The only reason this will probably work is because my "search space" as it is, isn't particularly large (just a very general, anecdotal observation, mind you). Since the project is only specific to my Department, we have their own limits imposed. So the number of students can't exceed 100 and the number of preferences won't exceed 10. for student in a dictionary/list/whatever of students: where i = 0 take the (i)st student, (i+1)nd student for their ranks: allocate the projects and set local_weighting to be sum(student_i.alloc_proj_rank, student_i+1.alloc_proj_rank) these are the cases: if local_weighting is 2 (i.e. both ranks are 1): then i += 1 and and continue above if local weighting is = N>2 (i.e. one or more ranks are greater than 1): let temp_local_weighting be N: pick student with lowest rank and then move him to his next rank and pick the other student and reallocate his project after this if temp_local_weighting is < N: then allocate those projects to the students move student with lowest rank to the next rank and reallocate other if temp_local_weighting < previous_temp_allocation: let these be the new allocated projects try moving for the lowest rank and reallocate other else: if this weighting => previous_weighting let these be the allocated projects i += 1 and move on for the rest of the students So, questions: This is sort of a modification of simulated annealing, but any sort of comments on this would be appreciated. How would I keep track of which student is (i) and which student is (i+1) If my overall list of students is 100, then the thing would mess up on (i+1) = 101 since there is none. How can I circumvent that? Any immediate flaws that can be spotted? Extra info: My students dictionary is designed as such: students[student_id] = Student(student_id, student_name, alloc_proj, alloc_proj_rank, preferences) where preferences is in the form of a dictionary such that preferences[rank] = {project_id}

The error is this: /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/dependencies.rb:131:in `const_missing': uninitialized constant Rails::Plugin::OpenID (NameError) from /Users/kimptoc/Documents/ruby/borisbikes/borisbikestats.pre3/vendor/plugins/open_id_authentication/init.rb:16:in `evaluate_init_rb' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:182:in `call' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:182:in `evaluate_method' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:166:in `call' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:90:in `run' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:90:in `each' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:90:in `send' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:90:in `run' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:276:in `run_callbacks' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/actionpack-2.3.9/lib/action_controller/dispatcher.rb:51:in `send' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/actionpack-2.3.9/lib/action_controller/dispatcher.rb:51:in `run_prepare_callbacks' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/rails-2.3.9/lib/initializer.rb:631:in `prepare_dispatcher' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/rails-2.3.9/lib/initializer.rb:185:in `process' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/rails-2.3.9/lib/initializer.rb:113:in `send' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/rails-2.3.9/lib/initializer.rb:113:in `run' from /Users/kimptoc/Documents/ruby/borisbikes/borisbikestats.pre3/config/environment.rb:9 from ./test/test_helper.rb:2:in `require' from ./test/test_helper.rb:2 I have these gems installed: $ gem list *** LOCAL GEMS *** actionmailer (2.3.9) actionpack (2.3.9) activerecord (2.3.9) activeresource (2.3.9) activesupport (2.3.9) authlogic (2.1.3) bundler (1.0.7) gravtastic (2.2.0) linecache (0.43) mocha (0.9.10) newrelic_rpm (2.13.4) parseexcel (0.5.2) rack (1.1.0) rack-openid (1.1.1) rails (2.3.9) rake (0.8.7) ruby-debug-base (0.10.5.jb2, 0.10.4) ruby-debug-ide (0.4.15) ruby-openid (2.1.8, 2.1.7, 2.0.4) sqlite3-ruby (1.3.2) The bundler Gemfile is as follows: source 'http://rubygems.org' #gem 'rails', '3.0.3' gem "rails", "2.3.9" gem "activesupport", "2.3.9" gem "ruby-openid", "2.1.7", :require => "openid" #gem "authlogic-oid", "1.0.4" # Bundle edge Rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git' gem 'sqlite3-ruby', :require => 'sqlite3' gem "authlogic", "= 2.1.3" gem "newrelic_rpm" # gem "facebooker" gem "parseexcel" gem 'gravtastic', '= 2.2.0' gem "rack-openid", '=1.1.1', :require => 'rack/openid' # not sure what this does... gem "mocha" I have these plugins installed: 2dc_jqgrid authlogic_openid open_id_authentication squirrel I see these similar questions: Missing a constant on load.. how can i get around this? and Requiring gem in Rails 3 Controller failing with "Constant Missing" But their solutions dont seem to work for my situation. I am guessing the issue is around the plugins, but my ruby-foo is too weak. Thanks in advance, Chris
