• Roles / Permissions framework for c#?

  - by mark smith

  Hi there, Does anyone know of a good framework to allow me design permission and roles against users. Basically allowing me to automatically check a user can do a certain thing, and then disabling or enabling menu items etc I am not really looking for asp.net security ... as i need to use it in my own service layer and clients both WEB and WPF will use it. I was hoping for something that allows me to create new roles and groups against users and then check what type of permissions a user has or a group has Any help really appreciated.. I am sure some kind of open source framework is available, well i was hoping not having to create my own Thanks

• Is it required to generate java classes to use spring-ws client

  - by vishnu

  Hi, I want to use spring ws to create the webservice client. I have seen some documentation. In all using jaxb marshalling and unmarshalling. But to start of need to create java classes from xsd. I tried to download the elcipse plugin for this. The location in java.net is not showing any thing to download. Sourceforce net showing the link to download. But that plugin is not working. I have tried wsimport, but it is generating only .classes? My question is if i want to use spring ws, is it required to generate .java classes? If so where can i find the elipse plugin or how to generate the classes? Is there any other way we can do without generating these classes?

• Nhibernate not tracking changes

  - by Lavinski

  I'm using nhibernate and it appears that changes to my new object are not persisted. After creating and saving an object I then modify it and commit the transaction. However none of the modifications are saved. The strange thing is this code was working previously and I have no idea what could cause this. Nothing was changed that's obviously related.. As an attempted work around I saved the object later in the procedure after all the changes where made however I was greeted with an Assertion Failure collection [] was not processed by flush. Any ideas?

• Understanding OpenGL Matrices

  - by Omega

  I'm starting to learn about 3D rendering and I've been making good progress. I've picked up a lot regarding matrices and the general operations that can be performed on them. One thing I'm still not quite following is OpenGL's use of matrices. I see this (and things like it) quite a lot: x y z n ------- 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 So my best understanding, is that it is a normalized (no magnitude) 4 dimensional, column-major matrix. Also that this matrix in particular is called the "identity matrix". Some questions: What is the "nth" dimension? How and when are these applied? My biggest confusion arises from how OpenGL makes use of this kind of data.

• Implicit casting Integer calculation to float in C++

  - by Ziddiri

  Is there any compiler that has a directive or a parameter to cast integer calculation to float implicitly. For example: float f = (1/3)*5; cout << f; the "f" is "0", because calculation's constants(1, 3, 10) are integer. I want to convert integer calculation with a compiler directive or parameter. I mean, I won't use explicit casting or ".f" prefix like that: float f = ((float)1/3)*5; or float f = (1.0f/3.0f)*5.0f; Do you know any c/c++ compiler which has any parameter to do this process without explicit casting or ".f" thing?

• Trying to run psexec to remote to server and recycle app pool

  - by James

  If I run this from my command prompt it works fine. psexec \ServerName cscript.exe iisapp.vbs /a AppName /r I'm trying to do the same thing with C# console app. I'm using the below code but most of the time the application hangs and doesn't complete, and the few times it does it throws an error code. Am I doing this wrong? Anyone know where I can look up the error or error code? static void RecycleAppPool(string sServer) { Console.Clear(); ProcessStartInfo p = new ProcessStartInfo("psexec.exe", "\\\\" + sServer + " cscript.exe iisapp.vbs /a <AppName> /r"); p.RedirectStandardInput = true; p.UseShellExecute = false; Process.Start(p); } When it completes with error, looks like this "cscript.exe exited with error code -2147024664"

• deselectRowAtIndexPath on an ABPeoplePickerNavigationController

  - by Josh Wright

  I'm showing an ABPeoplePickerNavigationController as a tab in my app. The user clicks a name, then email address, then I do something with the email address. Afterwards, I'd like for the person and property that they selected to fade out (not be highlighted). In a normal table, I'd call deselectRowAtIndexPath. But with the ABPeoplePickerNavCont I don't seem to have access to it's table, nor do I know what indexPath is selected, nor is there an api for deselecting the row. On most apps, ABPeoplePickerNavCont is used modally so it doesn't matter that the row is still highlighted 'cause the whole thing gets dismissed. But in my app it does not get dismissed (just like the contacts tab in the Phone app). Any ideas?

• Can't set background colour for UIView from ViewController

  - by Curyous

  I have the following code in the view controller: - (void)viewDidLoad { [super viewDidLoad]; ThemeManager *themer = [ThemeManager sharedInstance]; UIView *theView = self.view; UIColor *forBackground = [themer backgroundColour]; [theView setBackgroundColor:forBackground]; } but when execution gets to the setBackgroundColor line, I get the following error: *** -[NSCFNumber CGColor]: unrecognized selector sent to instance 0x1237c40 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFNumber CGColor]: unrecognized selector sent to instance 0x1237c40' There's got to be something simple that I'm doing wrong, how do I set the background colour? Do I have to subclass the view and do it in there? I'd prefer not to have the extra class, even though that is better separation of the whole model/view/controller thing. Update: value returned by [themer backgroundColour] is constructed using colorWithPatternImage:, could this make a difference?

• Who Knows AppWeb HTTP Server And It's Embedded PHP?

  - by Andi

  Hi all, on my search for a fast but comfortable web server I dropped into the homepage of EmbedThis(TM) AppWeb(TM) HTTP server. This one has 2 licencse models, GPLv2 and a commercial one with support. On the first view it looks good: the footprint is not too big, it is fast and it has a lot of configuration otions. The most important thing would be a fast PHP execution using a built-in PHP library. Unfortunately this PHP library doesn't include every option, especially "gettext" which one I need for I18N. My target platform is Linux on an embedded device with an ARM based CPU. Does anybody have experiences with the issues mentioned above? Kind regards, Andi

• small javascript problem

  - by dfg

  Hi, I have this little function that opens modal window type thing. The problem is that it doesnt work on IE. All other browser its fine, but on IE, nothing happends: function showOverlayBox() { if( isOpen == false ) return; $('#full').css({ display:'block', left: ( $(window).width() - $('#full').width() )/2, top: ( $(window).height() - $('#full').height() )/2, position:'absolute' }); $('.BgCover').css({ display:'block', width: $(window).width(), height: $(window).height() }); } function doOverlayOpen() { isOpen = true; showOverlayBox(); $('.BgCover').css({opacity:0}).animate( {opacity:0.8} ); return false; } function doOverlayClose() { $('#full').css( 'display', 'none' ); $('.BgCover').animate( {opacity:0}, null, null, function() { $(this).hide(); } ); } Maybe something to do with isOpen == false?

• Win32 call order

  - by DD

  Hi all, I have two windows that I send scripted input to. The procedure goes as this BringWindowToTop( window1 ); i = Build input structures( window1 ); SendInput(i); BringWindowToTop( window2 ); i = Build input structures( window2 ); SendInput(i); I was having trouble with inputs not being sent and the correct time. I put delays after each call and saw that input from the first SendInput() was processed after window2 is brought to top. Same thing at the end of the loop as well. Are SendInput calls buffered? If so, how can I make sure of a serial execution of this code? Thanks

• Handling over-long UTF-8 sequences

  - by Grant McLean

  I've just been reworking my Encoding::FixLatin Perl module to handle over-long utf8 byte sequences and convert them to the shortest normal form. My question is quite simply "is this a bad idea"? A number of sources (including this RFC) suggest that any over-long utf8 should be treated as an error and rejected. They caution against "naive implementations" and leave me with the impression that these things are inherently unsafe. Since the whole purpose of my module is to clean up messy data files with mixed encodings and convert them to nice clean utf8, this seems like just one more thing I can clean up so the application layer doesn't have to deal with it. My code does not concern itself with any semantic meaning the resulting characters might have, it simply converts them into a normalised form. Am I missing something. Is there a hidden danger I haven't considered?

• Creating multiple markers in Google Maps using XML

  - by Jessica Stanley

  I'm almost sure this question has been asked before, but for the love of me I just can't find the answer anywhere. Basically what I want to do is create multiple markers on a custom Google Map I'm building. I already have an XML file with the coordinates (lat/lng) and title of each item. I'd like to take the data from the XML file and use it to create markers on the map. I've found how to do this using KML files and MySQL/PHP, but I need to know how to do it in Javascript. One more thing: I have a .xml file of my own, so it won't be like I'll be getting the data from a webpage because I believe (from research I've done today) that the code for that may be different. If anyone knows if this has been posted somewhere else before, could you please direct me there? I've literally been searching all day, this is my last resort. Thanks a ton!!!

• Is it posible to Build & Run on TWO iPhones/iPods at once?

  - by Dimitris

  When I connect two iPhones at the same time to my computer and Build and Run a project the app only installs and plays on one of the devices. Now, with the iPhone 3.0, that supports bluetooth peer-to-peer connectivity, to test a multiplayer project you have to install and run it on two devices at the same time. It would be very helpful to be able to do that with one click instead of: install on one phone, disconnect, connect the other, wait a 10 seconds to recognize the phone and install again and run... Is anyone aware of a method to do such a thing? Thanks

• AutoCompleteExtender positioning menu incorrectly when scrolled

  - by Colin

  We have an AutoCompleteExtender linked to a TextBox. Both controls are placed inside an UpdatePanel, and the UpdatePanel is displayed as a pop-up dialog using a Javascript library (Ext.BasicDialog). The pop-up is a div on the page, not a separate window. The problem is that when the user scrolls inside the pop-up, the AutoCompleteExtender shows its menu in the wrong place. It looks like it is taking the visible distance from the top of the popup and positioning the menu from the top of the inner html of the popup (which is not visible) We are using Version 1.0.20229.20821 of the AjaxControlToolkit, and we are targetting ASP.NET Framework vewrsion 2.0. I have tried to fix the menu by attaching the following Javascript to the OnClientShown event, but it pretty much does the same thing: function resetPosition(object, args) { var tb = object._element; // tb is the associated textbox. var offset = $('#' + tb.id).offset(); var ex = object._completionListElement; if (ex) { $('#' + ex.id).offset(offset); } }

• DynamicMethod NullReferenceException

  - by Jeff

  Can anyone tell me what's wrong with my IL code here? IL_0000: nop IL_0001: ldarg.1 IL_0002: isinst MyXmlWriter IL_0007: stloc.0 IL_0008: ldloc.0 IL_0009: ldarg.2 IL_000a: ldind.ref IL_000b: unbox.any TestEnum IL_0010: ldfld Int64 value__/FastSerializer.TestEnum IL_0015: callvirt Void WriteValue(Int64)/System.Xml.XmlWriter IL_001a: nop IL_001b: ret I'm going crazy here, since I've written a test app which does the same thing as above, but in C#, and in reflector the IL code from that looks just like my DynamicMethod's IL code above (except my test C# app uses a TestStruct with a public field instead of the private value field on the enum above, but I have skipVisibility set to true)... I get a NullReferenceException. My DynamicMethod's signature is: public delegate void DynamicWrite(IMyXmlWriter writer, ref object value, MyContract contract); And I'm definitely not passing in anything null. Thanks in advance!

• UIView subclass draws background despite completely empty drawRect: - why?

  - by Pascal

  So, I have a custom UIView subclass which enables drawing of rounded edges. The thing draws perfectly, however the background always fills the whole bounds, despite clipping to a path first. The border also draws above the rectangular background, despite the fact that I draw the border in drawRect: before the background. So I removed the whole content of drawRect:, which is now virtually empty - nevertheless the background gets drawn! Anybody an explanation for this? I set the backgroundColor in Interface Builder. Thanks!

• How do I get Tycho?

  - by Jens Schauder

  Tycho is supposed to be a plug-in for maven for building eclipse plug-ins. I have found various blogs and other articles about it, but the contained links to Tycho are all dead or not accessible for the general public, for example: http://www.sonatype.com/people/2009/04/tycho-040-roadmap/ The only thing I found is a project proposal on the eclipse site, but it doesn't reference any downloads: http://www.eclipse.org/proposals/tycho/ I found a svn repository, but it seems to be extremely dated: http://svn.codehaus.org/m2eclipse/tycho/trunk/ So my question is: where do I get tycho from? Or is it dead and I should stop bothering? I doubt it's dead, since I found out there is a talk about it on JAX2010 ...

• What does class_eval <<-"end_eval", __FILE__, __LINE__ mean in Ruby?

  - by viatropos

  I'm learning how to use class_eval in modules (I'm somewhat familiar with class_eval) and came across this helpful class in resource_controller. In there they have things like this: class_eval <<-"end_eval", __FILE__, __LINE__ def #{block_accessor}(*args, &block) unless args.empty? && block.nil? args.push block if block_given? @#{block_accessor} = [args].flatten end @#{block_accessor} end end_eval What does __FILE__ and __LINE__ do in that context? I know __FILE__ references the current file, but what does that whole thing do exactly? Don't really know how to search for that :).

• How to browse a Matrix returned by the OpenCV2.0 Canny() function ?

  - by user290613

  Hi all, I've been browsing the web to get an answer but no way to put my hand on it. I call the Canny function that fills me a matrix Canny(src, dst, 220, 299, 3 ); the dst variable is now a Matrix that is according to me of type CV_8UC1, 8bit, 1channel. Now I would like to browse this matrix according to rows and columns, so there was a trick that I've seen on stackoverflow dst.at<uchar*>(3, 5) In my case it crashes. (Assertion Failed, unknown function, cxmat.hpp line 450) My matrix information are myMatrix.width() = 181 myMatrix.height() = 65 One more thing, when I do std::cout << dst.depth() << std::endl; It always retrieves me 0 and not 8 (which I guess Im suppose to get) Thank you very much for all who will reply,

• Maven: Unofficial artifact naming scheme?

  - by Sophistifunk

  I'm creating some Maven artifacts for various dependencies for our projects, and while I'm taking my best guess at group / artifact IDs, I'd like to add something to flag them as "unofficial" and created by us for compilation, so that should we find official sources for the same thing in the future there's no confusion and we can simply change to point to the identifiers. Is there a best/common/reccomended practice for doing so? I was just thinking something like setting groupId="org.providername.unofficial", but since Maven's all about "doing it our way" I just want to see if there's a precedent for something different already...

• Accurate Timings with Oscilloscopes on PC

  - by Paul Bullough

  In the world of embedded software (firmware) it is fairly common to observe the order of events, take timings and optimise a program by getting it to waggle PIO lines and capturing their behavior on an oscilloscope. In days gone by it was possible to toggle pins on the serial and parallel ports to achieve much the same thing on PC-based software. This made it possible to capture host PC-based software events and firmware events on the same trace and examine host software/firmware interactions. Now, my new laptop ... no serial or parallel ports! This is increasingly the case. So, does anyone have any suggestions as to go about emitting accurate timing signals off a "modern" PC? It strikes me that we don't have any immediately programmable, lag-free output pins left. The solution needs to run off a laptop, so using add-on cards that only plug into desktops are not permitted.

• Wordpress + VMware CSS path problem

  - by Stephen Meehan

  I posted a similar question earlier today but this question is clearer. I want to locally develop my Wordpress websites (on my Mac) and test them in Internet Explorer (6,7,8) on Windows XP. I can get the MAMP welcome screen to show in Windows XP, so I know VMWare is doing it's thing. The local URL for my site (on my Mac) is: URL (http://d3creative:8888/) But the local URL under VMware/Internet Explorer is: URL (http://192.168.2.1:8888/d3creative/) This is the only way I can get it to show up, problem is all the CSS styles are referencing the local Mac URL (http://d3creative:8888/) So understandably the CSS isn't showing up. Is there a way to tell Windows that "http://192.168.2.1:8888/d3creative/" should equal "http://d3creative:8888/" I've tried editing the "hosts" file within in Windows XP and I've rebooted after making any changes, but nothing is working. My software: MAMP Pro (v1.8.2) Wordpress (v2.8.6) Windows XP (SP3) Internet Explorer (6, 7, 8) Any help would be much appreciated. Stephen Meehan

• LocationMatch and DAV svn

  - by Homes2001

  Hi, I am trying to make our subversion repository accessible via multiple URLs. To do so, I was thinking to use the LocationMatch directive. My configuration is: <Location ~ "/(svn|repository)"> DAV svn SVNPath /opt/svn AuthzSVNAccessFile /etc/subversion/access </Location> The above configuration does NOT work ... Strange thing is that if i use for example this configuration, it works well for both URLs: <Location ~ "/(svn|repository)"> SetHandler server-status </Location> For me it looks like the combination of DAV svn and LocationMatch does not really work... or am I doing something wrong here?
