• How to apply multiple filters to sharepoint list

  - by Juraj Hajek

  Hi all, I have sharepoint list with several columns - month, year and some custom data. I want to provide 2 dropdowns to allow user select month and year to filter rows. I added "Choice Filter" webpart for month and set connection to list (this works). I added second "Choice Filter" for year and I wanted to do the same. However, I cannot set connection to list, because mylist is disabled in webpart menu "Edit-Connections-Send filter values to". How can I apply 2 filtering criteria? Thanks, Juraj

• ASP.NET: What's the best way to validate 3 drop downs boxes that are used to select a date (month, d

  - by Josh

  I have two sets of drop downs for start date and end date. Each date is created by selecting a month, day, and year from 3 separate drop downs. I currently have RequiredFieldValidators on all the drop downs (which just shows a * if nothing has been selected yet), but I need to validate that the end date is greater than the start date. I can take care of the logic behind comparing the dates, but in terms of the validation method used, can someone help me out (I essentially need to validate 6 drop downs all at one time)? I tried a custom validation using client side javascript but couldn't get it to work. Can you even validate multiple drop downs using ASP.NET validation controls? (which is what I would like to do - I can always write the javascript, but was trying to stay away from this). Thanks.

• Active Index is not being persisted in jQuery accordion change event

  - by Xaisoft

  I have an asp.net aspx page and on that page I have a hidden input field with and id of paneIndex. However, when I load the page, the alert shows index 1 which is correct on the first load, but if I open up pane 3 for example, the alert shows 1 still. Am I doing something wrong? In a Custom.js file, I have the following code: $(document).ready(function() { $("#accordion").accordion({ active: 1, collapsible: true, autoHeight: false, change: function(event, ui) { var activeIndex = $("#accordion").accordion('option', 'active'); $("#paneIndex").val(activeIndex); //alert(activeIndex); } }); }); In my server side button click, I have the following code: string activeIndex = Request.Form["paneIndex"]; string script = string.Format(@"<script type=""text/javascript"">var paneIndex = {0};</script>", activeIndex); if(!ClientScript.IsStartupScriptRegistered("JSScript")) ClientScript.RegisterStartupScript(this.GetType(),"JSScript", script);

• Membership systems for MVC4 that support RavenDB

  - by brad oyler

  I create a lot of quick "proof of concept" MVC apps and I actually found the SimpleMembership provider that shipped with the MVC4 templates to be very handy since it gets me up and running with user registration & OAuth in a matter of minutes. But...I've started to use RavenDb (on RavenHQ for a lot for my projects). So, I starting trying to implement my own "custom membership provider" based on the ExtendedMembershipProvider and while doing that I realized that didn't make much sense. I later stumbled upon 2 interesting projects that try to solve this exact problem: WorldDomination.Web.Auth: https://github.com/PureKrome/WorldDomination.Web.Authentication MemFlex: https://github.com/OdeToCode/Memflex Both are pretty interesting recent efforts and was wondering if these are the only ones being built right now. I'm essentially looking for nuget pkg that I can drop into a MVC4 app, connect to my RavenDb and be done. I'm willing to build this thing but don't want to duplicate any efforts that are already in motion. Thx!

• What are some ways to identify a logged in user on the web?

  - by farinspace

  Here is the scenario: There are 5 websites (different domain names) that need to share a session. I am using a bit of code on each site which returns a "blank.gif" image and at the same time sets the session (syncing it up to the current session). Each of the sites calls a session-img from each of the other sites. Also, all sites have access to the same database (where the session is stored). This works great on FF and Chrome, but not on IE (or Safari PC)... I need to come up with an alternative method to keep a session active? The app is a small custom CMS, so really only 2-3 people will be using it. I can probably identify user logins by IP and then continue to check for the IP accross all sites... Is there something more granular such as a computer uuid that i can check for?

• Google App Engine - Is os.environ reset between requests?

  - by Ian Charnas

  Hello I can't think of a way to test this and was hoping someone here knew the answer... I'm storing some request-specific data in os.environ, and was wondering if that data was going to leak to other requests. Does anyone know? Yes I realize that it's normal to use request.environ for this, and usually I do, but I want to store the currently authorized user ID (I'm using custom auth, not GAE auth) inside os.environ so that the models know the currently logged in user (remember, they don't have access to request.environ) without me having to pass the request object to just about every single model method. any help would be greatly appreciated Ian

• In C# is there a function that correlates sequential values on a IEnumerable

  - by Mike Q

  Hi all, I have a IEnumerable. I have a custom Interval class which just has two DateTimes inside it. I want to convert the IEnumerable to IEnumerable where n DateTimes would enumerate to n-1 Intervals. So if I had 1st Jan, 1st Feb and 1st Mar as the DateTime then I want two intervals out, 1st Jan/1st Feb and 1st Feb/1st March. Is there an existing C# Linq function that does this. Something like the below Correlate... IEnumerable<Interval> intervals = dttms.Correlate<DateTime, Interval>((dttm1, dttm2) => new Interval(dttm1, dttm2)); If not I'll just roll my own.

• Serialising and Deserialising Requests and Responses exactly as WCF does

  - by PeteAC

  I need to deserialise SOAP request XML to .Net request object and to serialise .Net response object to SOAP response XML. I need this to work exactly as WCF does, using the same XML element local names and namespace URIs. The .Net request and response classes were generated from WSDL using SVCUTIL. I have looked at XmlSerializer class, which does most of it, but doesn't take notice of certain WCF-specific custom attributes, like MessageBodyMemberAttribute. I also looked at DataContractSerializer, but that had exceedingly strange ideas about what element names and namespaces to use. Finally, I tried XmlSerializer with an XmlTypeMapping generated by a SoapReflectionImporter; this didn't seem to use any namespaces at all. I rather suspect that I need to be using one of the above techniques, but with some additional subtlety, of which I am unaware. But perhaps there is an entirely different approach? All suggestions welcome.

• When is it useful to define your own delegates instead of using the generics?

  - by Carlos

  I've been going through some old code, where I came across some custom defined delegates, which are used thus: private delegate void ListenDelegate(UdpClient listener, bool multicast); private void ListenOn(UdpClient listener, bool multicast) { new ListenDelegate(_ListenLoop).BeginInvoke(listener, multicast, null, null); } With some of the new .NET framework versions, you can do the following: private void ListenOn(UdpClient listener, bool multicast) { new Action<UdpClient, bool>(_ListenLoop).BeginInvoke(listener, multicast, null, null); } This ought to be exactly the same. Is there any point in defining your own delegates, when the generic delegates seem to do the same job with less space? Or have I missed something about the generics that makes them not equivalent?

• AJAX XMLHttpRequest POST X-Domain

  - by Tom

  Hi Guys, I am sending an AJAX request using POST over X-Domain for a widget we are producing for our website. The problem we are facing is that this is getting blocked. My question is - for "modern browsers" [Chrome, Safari, FF, IE8] - it is my understanding that setting "Access-Control" headers Access-Control-Allow-Origin: http://www.test.com Access-Control-Allow-Methods: POST, GET, OPTIONS Access-Control-Allow-Headers: * Access-Control-Max-Age: 1728000 Will allow these "POST" requests to work ? But for IE7 we need to implement some "custom" JSONP solution? Am I correct in this ?

• Is it possible to query a XML file with SQL?

  - by Monty

  Currently I'm working on a case where we don't want to change to much on a c#/wpf program, but like to add a feature. Currently we allow certain users to add sql queries to a database to retrieve customer data, hereby a custom connection string/ provider name must be specified. With this information it's possible to create the connection and obtain the data with c#. However we like to add the possibility to allow that user group to query XML files too, with a certain connection string/ provider name. I just had a look for possibities in .net to do that, but can't seem to find a decent way... Is something like this possible? (OleDb/ODBC way maybe?) Thanks in advance.

• Separate groups of objects based on their properties

  - by Bevin

  I want to separate an array of my custom object into several arrays, based on the values of their two properties. The struct looks like this: struct MyStruct { public string Person { get; set; } public string Command { get; set; } } Now, if I have an array with a few objects: {Person1, cmd1} {Person1, cmd3} {Person2, cmd3} {Person3, cmd2} {Person2, cmd4} I want to be able to place them into one array for each person, that lists all of the commands for that person: {Person1: cmd1, cmd3} {Person2: cmd3, cmd4} {Person3: cmd2} I hope I've made it clear with my descriptions. I would assume that there is an elegant way to do this with LINQ, but I have no idea where to start.

• When to rewrite vs. upgrade?

  - by MrGumbe

  All custom legacy software needs changing, or so say our users. Sometimes they want a feature or two added and all that is necessary to change a bit of code, add a control, or some other minor upgrade task. Sometimes they want to ditch their error-prone VB5 desktop solution and rewrite the whole thing as a rich Web 2.0 ASP.NET MVC application. More often, however, the scope of changes to legacy functionality lies somewhere between these two extremes. What rules of thumb to you use to decide whether you should upgrade an existing application or start from scratch?

• iphone getting hours/min/seconds app crashes.

  - by coure06

  i have this code in my overridden drawRect method NSDate *date = [NSDate date]; NSCalendar *calendar = [NSCalendar currentCalendar]; unsigned int unitFlags = NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit; NSDateComponents *comp = [calendar components:unitFlags fromDate:date]; NSInteger h = [comp hour]; NSInteger m = [comp minute]; NSInteger s = [comp second]; NSLog(@"%i,%i,%i", h,m,s); NSLog(@"test"); [date release]; [calendar release]; [comp release]; I am calling drawRect using setNeedsDisplay from my custom method (timer based after each 1 secon). It runs only once and then app exit automatically. If i comment out all the code and just write NSLog(@"test"); then application works ok, it logs "test" after each 1 sec.

• GoogleMaps API v3 - Need help with two "click" event scenarios. Need similar functionality to v2 AP

  - by Nathan Raley

  In version 2 of the API the map click event returned an Overlay, LatLng, Overlaylatlng. I used this to create a generic map event that would either retrieve the coordinates of the Map click event, or return the coordinates of a Marker or other type of Overlay. Now that API v3 doesn't return the Overlay or Overlaylatlng during the map click event, how can I go about creating a generic "click" event for the map that works if the user clicks on a marker or overlay? I really don't want to create a click event for each marker I have on my page as I am creating anywhere from a handful to a couple thousand markers. Also, I had to create a custom ImageMapType in order to display the StreetViewOverlay like we could do in v2 of the API because I couldn't find anywhere that told me how to add the StreetViewOverlay without the pegman icon. How can I go about retrieving the LatLng coordinates of a click on this overlay type as well?

• How to use Visual Studio and IIS7 together?

  - by Pure.Krome

  Hi folks, i'm trying to use Visual Studio 2010 (but this also happens with VS2008) as my web server for all locahost development. When i go into the properties for my web application (sigh, it's a legacy web FORMS app) and check the Web tab .. then check the Use Local IIS Web Server option ... it only allows me to create a virtual directory against a website. Why?! this is not what I want :( I wanted to have my own IIS7 website (no virtual directory) and debug against that. Can anyone help me? As a side note, i tried to use the third option Use Custom Web Server .. which ends up pointing to my localhost iis7 server. Now, this works ... but when i wish to Start Debugging .. it errors :( (it's not sure how to attach to that process or something?) So - can anyone out there please help?

• Python 3-compatibe HTML to text converter preserving basic structure under permissive licence?

  - by hawk64

  I am looking for a relatively simple HTML to text converter which displays links and works on strings. So far I have tried lynx but performance is too bad, html2text which gives weird and verbose markdown output and is under GPLv3 which is too restrictive for my (BSD-licensed) project, http://effbot.org/librarybook/formatter-example-3.py using htmllib.HTMLParser with formatter.AbstractFormatter and a custom writer, however htmllib.HTMLParser is drpeceated and has been removed from Python 3. So is there any simple, performant, Python 3-compatible HTML to text converter under a permissive license such as MIT/BSD/Apache and the like? Edit: I dont just need something to strip HTML-Tags but also to preserve the basic structure of the HTML, that is output that somewhat resembles that of Lynx.

• iphone view controller class - how to

  - by Brodie4598

  Hello - I need to create my own UIView class and it is not something I have had to do. I created the class, then laid out the small view in IB (it's just a few labels that i will later need to add data to ). but now im stuck on how to actually put an instance of it in my main view. Can someone point me in the direction of a good tutorial? The closest thing I have done to this is creating a custom tableViewCell. DataTagViewController *dataTag = [[DataTagViewController alloc]init]; [theMap addSubView: dataTag];

• Getting text after URL in asp.net / URL Rewriting (sort of!)

  - by alex

  My app is a very simple "one page" type app- It has Default.aspx I'm basically trying to get, for example: www.myappurl.com/this is my text I want to get hold of "this is my text" from the above example. This will be displayed on the page (for now) I didn't really want to have to use any complext url rewriting things for this... (My hosting provider uses IIS6) I tried using a 404 handler, but this is a bit long winded, and i'm using shared hosting, that can't set the "execute url" on custom 404 pages. Any other ideas?

• Mask image does not appear on the screen

  - by Ponty

  I have imported to the library two images and have given them the custom class names MaskImage and MaskedImage. Then i write the code: package { import flash.display.*; public class MaskDemo extends Sprite { // Properties private var sprMaskedImage:Sprite; private var sprMaskImage:Sprite; private var bmMaskedImage:Bitmap; private var bmMaskImage:Bitmap; // Constructor public function MaskDemo() { do_magic(); } // Methods private function do_magic():void { bmMaskedImage = new Bitmap(new MaskedImage(0, 0)); bmMaskImage = new Bitmap(new MaskImage(0, 0)); sprMaskedImage = new Sprite(); sprMaskedImage.addChild(bmMaskedImage); sprMaskImage = new Sprite(); sprMaskImage.addChild(bmMaskImage); sprMaskedImage.mask = sprMaskImage; this.addChild(sprMaskImage); } } } But it does not appear anything on the display. Any ideas why is happening that?

• What can you do in the ant Task.init() method?

  - by skiphoppy

  I'm developing a few custom ant tasks that all need to initialize the same objects. I wanted to initialize those object's in a common superclass that extends from Task, in the init() method. But I see from the lifecycle of an ant task that init() gets called before the tasks child elements and attributes are set. So all of the data I need for initializing those objects is unavailable during init(), if I am reading right. So, why is init() called at this point? What do you even know that you could use in init()? What could it be used for? (And is there some other method that I can rely on to be called before execute(), but after my data is available?)

• Override l() function in Drupal

  - by Marco

  I'm currently working on a Drupal site (6.*), which when in production mode will be accessed through some kind of http proxy, which means I will have to rewrite all the links for my custom theme if the $_SERVER['HTTP_X_FORWARDED_SERVER'] variable is set to the domain people will access the site from. The site has a lot of internal linking, mostly through Views. My thought is that the easiest way to solve this would be to hook into the url() and/or the l() functions and post process the url before returning it if HTTP_X_FORWARDED_SERVER is set. My problem is that I can't figure out how to hook into these functions, or if it's even possible without touching the core, has anyone had to do this? How did you solve it?

• Reporting system for organization. Architecture advise required

  - by Andrew Florko

  We have several legacy & 3'd-party systems in organization that use several RDBMS vendors (& more specific data storages). Cross-system data reporting (as well as extra-reports that are not implemented in 3'd-party systems) is required with charts and population of templates (winword, excel). Reporting system is visioned as intranet web-site with custom user access to reports. We expect ~50 reports per day. Would you suggest to use BizTalk or any other integration software if commercial-department doesn't plan to buy anything expensive. Would you suggest to create centralized data storage for reporting that is populated regularly or rely on on-demand services that providers always up-to-request data. Thank you in advance!
