• nested repeaters - how to sort

  - by Cristian Boariu

  Hi guys, I have a table: Category with some sort of categories category1 category2 category3 I have another table Subcategory which has a fk to Category. So, each category1 can have subcategoryB, subcategoryA, subcategoryZ. Well... i've made two repeaters. The first one is binded to a linq data source which takes the categories from the parent table. The children repeater is binded to that foreign key like: DataSource='<%# Eval("Subcategories_1s") %' So the result is: category1 subcategoryB subcategoryA subcategoryZ category2 etc. Well, the strange question is: how can i order the subcategories alphabetically? If i'd have binded the children repeater to a linq it would be easy. But in this case...?

• Github - what is it really?!

  - by Fiona

  ok.. this might seem like a strange question but my idea of Github and that of my boss is very different. From what I can tell its a version control tool. My boss seems to think that it will connect to the server where we're hosting our webapp and when changes are committed on github that these get applied to the server to... If this is the case how do I connect github to my server? Many thanks for helping me with what might seem like a stupid question but I've searched forums, articles and I'm more confused than ever!

• Debugging ASP.NET on a built-in web server suddenly stops

  - by Anton Gogolev

  I have Windows Server 2008 (64-bit), VS 2008 with its built-in webserver and an ASP.NET MVC 1.0 webapp. All I'm trying to do is to debug said app. I have a bunch of breakpoints, but they behave in a very strange way. When I fist start a debugging session with F5 and hit a breakpoint, the debugger stops just fine. However, after serveral F10s/F11s debugging suddenly "stops" (no exceptions at that time), but neither VS detaches from browsers' process, nor webapp execution stops: Visual Studio stays attached, and web request continues executing as usual. I tried various browsers (Chrome, Firefox, IE), but to no avail. What do I do to solve this? It really drives me insane.

• C# NotifyIcon behaviour on Windows 7 with MouseClick, MouseDoubleClick events

  - by binball

  Hi, I have strange behaviour with my app after run it on Windows 7. It's connected with NotifyIcon while app is minimized. What should happens: 1) Click once on icon with mouse left button then Balloon with some text should appears 2) Double click on icon will show again app window On Windows 7 MouseDoubleClick is also fired but window is not showing. I don't know why. The same code works good on Windows XP. private void notifyIcon_MouseClick(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { this.NotifyIconShowBalloonWithData(); } } private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e) { this.Show(); WindowState = FormWindowState.Normal; notifyIcon.Visible = false; } What did I wrong? :) Thanks in advance for your answer.

• "Dealing with uncertainty" - Entity Framework CodeOnly

  - by Simon Fox

  This is a bit of a strange one but I've just seen something on twitter which kind of baffled me and I'm interested to know more. Rob Conery tweeted the following a couple of hours ago: Class name of the day: "Maybe<T>". Method of the day: "ToMaybe<T>()". He then went on to offer a Tekpub coupon to anyone who could guess where it came from. He linked to a further tweet which had a clue and from that I worked out that it was Entity Framework Code-Only but while trying to determine the usage someone else answered to which Rob replied ...EF CodeOnly - dealing with uncertainty.... So my question boils down to what exactly is he referring to with uncertainty and how does this fit in to Entity Framework Code-Only?

• AesCryptoServiceProvider not part of SymmetricAlgorithm?

  - by user330006

  I have a quick little app that steps through the possible symmetric encryption methods. I get them with the following line: private static List<Type> GetAlgorithmTypes { get { return Assembly.GetAssembly(typeof(SymmetricAlgorithm)).GetTypes().Where( type => type.IsSubclassOf(typeof(SymmetricAlgorithm))).ToList(); } } As you can see when i run this, AesCryptoServiceProvider is not a member of this group, even though it inherits from AES, which does belong to SymmetricAlgorithm and shows up in my list. This wouldn't be so much of a problem, i can manually add the provider in the group if i have too, but then if i try to retrieve this type by its name: Type t = Type.GetType("System.Security.Cryptography.AesCryptoServiceProvider"); i get a null object for AesCryptoServiceProvider, but not for any of the other items in the group. This is really strange, and i'm wondering if anyone has any ideas. It's kinda making me need to use tripleDES because of this (since my machines are all running the FIPS compliance requirement). Thanks for any help!

• Sending BCC emails using a SMTP server?

  - by Alix Axel

  I've had this noted down on some of my code for a while: /** * Add a BCC. * * Note that according to the conventions of the SMTP protocol all * addresses, including BCC addresses, are included in every email as it * is sent over the Internet. The BCC addresses are stripped off blind * copy email only at the destination email server. * * @param string $email * @param string $name * @return object Email */ I don't remember where I got it from but that shouldn't be relevant to this question. Basically, whenever I try to send an email with BCCs via SMTP the BCC addresses are not hidden - I've read the whole RFC for the SMTP protocol (a couple years ago) and I don't think I'm missing anything. The strange thing is, if I send an email with BCCs using the built-in mail() function everything works just right and I've no idea why - I would like to roll my own email sender but I fail to understand this. Can someone please shed some light into this dark subject?

• LINQ-to-SQL and SQL Compact - database file sharing problem

  - by Eye of Hell

  Hello. I'm learing LINQ-to-SQL right now and i have wrote a simple application that define SQL data: [Table( Name = "items" )] public class Item { [ Column( IsPrimaryKey = true, IsDbGenerated = true ) ] public int Id; [ Column ] public string Name; } I have launched 2 copy of application connected to the same .sdf file and tested if all database modifications in one application affects another application. But strange thing arise. If i use InsertOnSubmit() and DeleteOnSubmit() in one application, added/removed items are instantly visible in other application via 'select' LINQ queue. But if i try to modify 'Name' field in one application, it is NOT visible in other applicaton until it reconnects the database :(. The test code i use: var Items = from c in db.Items where Id == c.Id select c; foreach( var Item in Items ) { Item.Name = "new name"; break; } db.SubmitChanges(); Can anyone suggest what i'm doing wrong and why InsertOnSubmit()/DeleteOnSubmit works and SubmitChanges() don't?

• drupal bootstrap script: how to get list of all nodes of type x?

  - by groovehunter

  hi. I create a custom import and export, at the moment as an external script (via bootstrap), i plan to create a module in a more generic fashion lateron. I am building a frontend for nagios and for our host management and nagios configuration btw. Maybe it might become useful for other environments (networkmanagement) Now i need to know how to get list of all nodes of type x? I want to avoid direct SQL. A suggestion i got was to make an rss and parse it but i acess the drupal db a dozen times to extract various nodes, so it feels strange to do a web request for one thing So what i am looking for as newbie drupal dev is just a pointer to basic search module api for this task TIA florian

• Error "E_UNEXPECTED(0x8000FFFF)" when using CDec/CInt/IsNumeric

  - by Marc vB

  I have encountered a strange problem, which I could solve but don't understand why it did occur. I have build a DLL with COM enabled. In this DLL I have classes that did use the functions CInt, CDec and IsNumeric. If I test these classes from a .NET application then it works ok. But when I called/run these classes from a Win32 application (with COM) then I did get an "E_UNEXPECTED(0x8000FFFF)" error. After some debugging I found out that the problem would go away if I: - replaced IsNumeric with Integer.TryParse or Decimal.TryParse - replaced CInt with Integer.Parse - replaced CDec with Decimal.Parse Can anyone explain this? Again, I could solve it by doing this but I would like to know why.

• crazy things with PHP array...

  - by user296516

  Hi, A very strange thing, I have an array where element 7 is '[1000137d]', but when I try to compare it by using if ( $array[7] == '[1000137d]' ) it will return a negative. echo $array[7]; echo '<br>'; echo '[1000137d]'; echo '<br>'; echo md5($array[7]); echo '<br>'; echo md5('[1000137d]'); this code would echo out: [1000137d] [1000137d] ca9983334e720042e3a6cbb1dd6b7fd2 3b1c21e661bd7d38deda1f4a45eaa23b as you can see $array[7] is identical to [1000137d], yet their md5's differ. what do you think might be the problem? Thanks!

• HttpContext User value changing on its own?

  - by larryq

  Hi everyone, I'm working on an ASP.Net 2.0 application and am having a strange issue involving the HttpContext User. It appears to be changing on its own when I go to a particular page/directory. All of our pages inherit from a base page. In that base page's Page_Load() method we run an authorization check to see if the user can see the page they're going to. We retrieve the user to check against with this code: GenericPrincipal objPrincipal = (GenericPrincipal)Context.User; When I go to this unusual directory the User value isn't me, it's some other username I've never heard of. This username isn't authorized to see these pages, so authorization fails. This mysterious directory isn't a virtual web, just a regular directory in our website, however I've noticed it has its own Web.Config file. I'm guessing that's a cause of the trouble here. My question is, how can I investigate this further, in determining what's changing the User value when I go to this directory?

• Java regex basic usage problem

  - by Ernelli

  The following code works: String str= "test with foo hoo"; Pattern pattern = Pattern.compile("foo"); Matcher matcher = pattern.matcher(str); if(matcher.find()) { ... } But this example does not: if(Pattern.matches("foo", str)) { ... } And neither this version: if(str.matches("foo")) { ... } In the real code, str is a chunk of text with multiple lines if that is treated differently by the matcher, also in the real code, replace will be used to replace a string of text. Anyway, it is strange that it works in the first version but not the other two versions.

• How to determine what in my script is blocking my HTML rendering?

  - by Vicki

  I have a web application that uses quite a bit of JavaScript. When the page loads, it's very clear visually that something is blocking the rendering of a particular portion of the web site. This portion is generated by a Tabber Tabify JavaScript library. How can I determine what's blocking the HTML rendering specifically so that I can modify my code to prevent this blocking? Can I use Firebug, or some other tool, to walk through my HTML/JavaScript to determine where the HTML rendering is being blocked and if so, how? UPDATE: YSlow gives my web-application a score of "A" and Page Speed give a score of 94/100. UPDATE 2: The live site is linked below. http://www.uptownelite.com/index.uncompressed.html?city=Dallas,TX What I'm specifically referring too is the actual Tabs themselves being rendering (and NOT the panel content inside the tab panes). It seems strange to me that the Tab headings themselves are taking so long to generate on the first (empty cache) page load.

• How to solve the performance decay of a VB.NET 1.1 application?

  - by marco.ragogna

  I have single-thread windows form application written with VB.NET and targeting Framework 1.1. The software communicates with external boards through a serial interface, and it mainly consist of a state machine that run some tests, driven in a loop done with a Timer and an Interval of 50ms. The feedback on the user interface is done through some custom events raised during the tests. The problem that is driving me crazy is that the performance slightly decrease over time, and in particular after 1200/1300 test operations. The memory occupied does not increase over time, it is only the CPU that seems interested by this problem. The strange thing is that, targeting framework 2.0 and using the same identical code, I do not have this problem. I know that is difficult without looking at the code, but do you have suggestions how can I approach the problem?

• What are the common issues that can cause slow boot times of Windows CE6 Images?

  - by Psychic

  I am relatively new to Platform Builder, and whilst I am able to produce nk.bin files, they boot very slowly, 80-100 seconds, so I think there may be some checkbox somewhere that I need to set (or clear)! I've already removed kitl, profiling, etc in the project settings, and set the project to 'release build' & 'ship'. When I looked at the startup event log (in debug), there doesn't appear to be any specific point where it is slow. The log pretty much scrolls all the way through with no major pauses. One thing I found strange was that although the nk.bin file was a lot smaller in release build (just under 12Mb), the boot time didn't noticeably change from the debug build... The board is a Vortex86DX_60A and I'm building CE6. Are there any 'common builder mistakes' that I may be missing here, or is this going to be something a little deeper?

• PEP8: conflict between W292 and W391

  - by seler

  As far as I know in unix it's a good practice to always have blank line at the end of file - or to put it in other words: every line should end with \n. While checking my python code with PEP8 I noticed that it also states that there should be \n at end of file: W292 no newline at end of file JCR: The last line should have a newline. What's strange, it conflicts with W391: W391 blank line at end of file JCR: Trailing blank lines are superfluous. Okay: spam(1) W391: spam(1)\n How it should be? Should I have blank line at the end of file or not?

• ria entity remove bug

  - by Greg

I am creating a new entity of type "House" and add it to context without saving the context so the id of the new entity is 0, after i remove this entity and add another new entity of type "House" again and again without saving the context, here comes the weird part, now I have an entity of type "City" which holds entityset of all "Houses" in that city, so to put the newly created entity "House" into the city i do something like this - house.City = city, where house is type "House" and city is type "City", afte this step a check the context and suddenly there are 2 entities of type "House" with id 0, one of them is the one I have deleted at the beginning. Any idea what is causing this and how to fix it?? thank you Greg

• Prototype Ajax.Updater Response OK, but not showing up in FF. working in Safari!

  - by koko

  Hi, I've got a quite strange problem here. I'm calling some simple code via Ajax.Updater: new Ajax.Updater('load','http://myurl.com/demo.pl?key=demokey&param1=xyz&param2=abc',{ method:'get', onComplete:function(transport){ alert(transport.responseText) } }); which gets some code like this: <img id="2009_04_15_1239786246" src='../pv/100/2009_04_15_1239786246-01.jpg' border="1"> <img id="2009_04_15_1239786066" src='../pv/100/2009_04_15_1239786066-01.jpg' border="1"> ... and so on This code shows up in my firebug console as my server response, so everything should be fine. No errors here at all. Works fine in Safari. Firefox, according to Firebug, knows there is a response, but it won't show a thing in my div 'load' and the alert(transport.responseText) is also empty. I have no idea what could be the problem here.

• Problem with images in upload directory after upgrading WordPress to 3.0

  - by Volmar

  I've developed a WordPress plugin and it wordked well from WP 2.0 and up to WP 3.0rc1 (haven't tried rc2) but now with rc3 and milestone 3.0 a strange and irritating error appeared. If you check out my demo page you will se that none of the cover-images is working. they are in the same place as before but they can not be hotlinked or show up when i enter the correct url. if i move the img-directory from /wp-content/uploads/my-record-collection/ to /wp-content/uploads/ the images show up if i enter the url, but not if i move it back inside my "my-record-collection"-folder. anyone know what change in rc3(or maybe rc2) that made this bug appear and what can be done to fix it?

• Declaring a function inside a function?

  - by nunos

  I have came across the following code, and being a c beginner, I came here for your help. This function is from a c implmentation of a queue. Bool queuePut(Queue *q, char c) { void beep(); if (queueFull(q)) { beep(); return false; } //do stuff return true; } So, I am getting a strange error with gcc on the void beep(). Can someone please explain me what is this, declaring a function inside a function. Or is it the void beep() simply out of place? I was given this code and there's always the possibility that it isn't correct. Thanks.

• Changing the namespace for a Web Reference in a Project to be Made Into a VS Project Template

  - by kdmurray

  When I add a web reference to a project, it comes up with a default namespace of: com.wpdevs.myservice. This is the namespace I'd have expected it to use in the application. When I add the using statement to the project, I have to add: using MyProject.com.wpdevs.myservice; I'd like to find a way to eliminate having to reference the project name in the using statement. The project I'm putting together now is destined to be converted into a VS Project template and having that rather strange reference in there, or even having a per-project reference, isn't something I'd like to have in the project.

• @font-face and CSS3 working locally but not on hosting

  - by iamfriendly

  Hello chaps and chapettes, I've got a bit of a strange one for you (so to speak). I've devised a little 'coming soon' page for my site which, locally, (on a WAMP setup) is working flawlessly - in capable browsers (i.e. Chrome and Safari), the page looks fine and has a nice little CSS3 transition effect upon hover. And in other browsers, the page visibly looks (practically) identical and the hover effect still works, just without the transition. After uploading to my hosting, the site still looks fine and works fine in Chrome and Safari, but for some reason in Firefox, the @font-face declarations don't seem to have worked and in IE the layout is slightly different. I'm massively puzzled! The files are identical on my hosting to what I have locally. The URL is http://iamfriendly.com/ The CSS Files are visible at: http://iamfriendly.com/wp-content/themes/iamfriendly_comingsoon/css/screen.css and http://iamfriendly.com/wp-content/themes/iamfriendly_comingsoon/css/typography.css Any suggestions would be greatly appreciated! Richard
