• Help with string manipulation function

  - by MusiGenesis

  I have a set of strings that contain within them one or more question marks delimited by a comma, a comma plus one or more spaces, or potentially both. So these strings are all possible: BOB AND ? BOB AND ?,?,?,?,? BOB AND ?, ?, ? ,? BOB AND ?,? , ?,? ?, ? ,? AND BOB I need to replace the question marks with @P#, so that the above samples would become: BOB AND @P1 BOB AND @P1,@P2,@P3,@P4,@P5 BOB AND @P1,@P2,@P3,@P4 BOB AND @P1,@P2,@P3,@P4 @P1,@P2,@P3 AND BOB What's the best way to do this without regex or Linq?

• autocomplete dropdown in Infragistics ultrawebgrid cell

  - by Rama

  Hi, I want to an autocomplete dropdown control in the ultrawebgrid cell in edit mode, so user can type the data and value is filled in automatically if exists, invalid data should not be permitted. is this possible? I don't want to use webcombo, it is too heavy and I don't need a multi-column dropdown. I want a simple dropdownlist, but the ability for the user to type just like Google suggest, but all the values cached on the client, no roundtrip to server on each key stroke. the control should be like the following one http://www.asp.net/AJAX/AjaxControlToolkit/Samples/ComboBox/ComboBox.aspx thanks, RK

• Android - Barcode Scanning, Options? Zxing?

  - by Donal Rafferty

  I want to create an application for Android that will be able to scan barcodes, get the information contained within the barcode and then be able to use that information in some way. I have no idea how to create a barcode scanner so I went Googling and it seems Zxing is the most commonly used way to implement a barcode scanner in an app. Some Links: http://code.google.com/p/zxing/ http://awalkingcity.com/blog/2008/08/25/qr-codes-made-easy-in-android/ http://stackoverflow.com/questions/2050263/using-zxing-to-create-an-android-barcode-scanning-app However the samples I found on zxing involved having to prompt the user to go to the market and install the zxing barcode scanner so that my app can then call the barcode scanner when its needed and the barcode scanner will then return the info to my app. While this would be a good starting point for me I was wondering is there any other options that would allow me to have a barcode scanner embedded in my own application without having to prompt the user to download a secondary application?

• Looking for search syntax documentation for SharePoint UserProfileManager.Search Method

  - by gregenslow

  Greetings - I have a SharePoint 2010 server running with the User Profile service setup to synchronize to Active Directory. I'd like to use the UserProfileManager.Search() method to return user profiles based on specific criteria. MSDN documentation for this method is here. It states that the method will return user profiles that match the specified search pattern. This is exactly what I want. However, there is no documentation on what a valid search pattern is. I've made a few guesses like "Department = 'HR'" but haven't had any luck. I can't find any other documentation or sample code. Can anyone provide samples of valid "search patterns?" Another way to return user profiles is to do a query using the FullTextSqlQuery object. We don't yet have Search setup on this server so this isn't currently an option. Thanks, Greg

• How to programatically self delete? (C# WinMobile)

  - by Christian Almeida

  How to programatically self delete? C# / .NetCF2 / Windows Mobile 6 Please, I don't want to discuss WHY to do it, I just need to know HOW to do it! Important: The "second application" approach is NOT an option. (Unless that second application can be "extracted" from running app, but I don't know how to do it!). No problem in forced reboot, if windows do the trick at startup. (Is it possible? Nice! Show me how!). Code samples are welcome.

• How Do I Use WkHtmlToXSharp in C#

  - by Dizzy49

  I've read a lot about WkHtmlToXSharp (wrapper for wkhtmltopdf) so I downloaded it. The one page that appears to be the only documentation states you only need the wkhtmltosharp.dll, but I can't find it in the file I downloaded. It appears to be several projects, and the thing that looks like a DLL in the Libs/Win64 folder won't load into my project. I'd GREATLY appreciate it if someone could point me to some instructions, and maybe some basic samples. I need to know where the .DLL is, what namespace to use, and general usage syntax to convert a HTML file to PDF. THANK YOU!!

• NServiceBus FullDuplex sample compiled and debugging against .NET 4.0 framework throws exception

  - by Jim

  I just installed VS2010 RC and launched the FullDuplex sample from NServiceBus 2.0.0.1145 and it ran fine. I then changed the target framework of each project in the solution to ".NET Framework 4", recompiled and launched in the debugger and received the following exception: System.InvalidOperationException was unhandled Message=No endpoint configuration found in scanned assemblies. This usually happens when NServiceBus fails to load your assembly contaning IConfigureThisEndpoint. Try specifying the type explicitly in the NServiceBus.Host.exe.config using the appsetting key: EndpointConfigurationTypeScanned path: C:\Development\Personal\ThirdParty\NServiceBus\samples\FullDuplex\MyClient\bin\Debug\ Source=NServiceBus.Host StackTrace: at NServiceBus.Host.Program.ValidateEndpoints(IEnumerable`1 endpointConfigurationTypes) in d:\BuildAgent-02\work\672d81652eaca4e1\src\host\NServiceBus.Host\Program.cs:line 189 at NServiceBus.Host.Program.GetEndpointConfigurationType() in d:\BuildAgent-02\work\672d81652eaca4e1\src\host\NServiceBus.Host\Program.cs:line 171 at NServiceBus.Host.Program.Main(String[] args) in d:\BuildAgent-02\work\672d81652eaca4e1\src\host\NServiceBus.Host\Program.cs:line 32 InnerException:

• What software license to use for commercial software?

  - by GONeale

  Hey there, Under what license agreement should you release software under if it's closed-source and for commercial use only? Are there multiple license types? (such with open source you have BSD, GNU/GPL etc..) If so, which one do I choose, and are there samples out there to get you started? I have heard the term and seen documents named EULA.txt for an End User License Agreement, but can't seem to find a definitive guide on the net as to how to structure one but do see this included with nearly every commercial app I have installed and don't know if it's as simple just to "change to suit your business". Can anyone shed some more light on this? Thanks guys. For further details - our software is non-redistributable, non-modifiable and the user is charged yearly.

• Getting WIF to work with OpenSSO as STS

  - by Tyler

  Hi gang, Using OpenSSO as an identity provider, what should I do (i.e. with FedUtil.exe) to configure my .NET relying party so that it will do the STS dance? I've gotten OpenSSO's WS-Trust client samples running, so I think OSSO's in a good state and ready for the next step. I'm at the FedUtil.exe's "Use an existing STS" wall. Where do I get the STS WS-Federation metadata document for OpenSSO? I've tried: the.osso.server:port/opensso/sts the.osso.server:port/opensso/sts?wsdl the.osso.server:port/opensso/sts/mex the.osso.server:port/opensso/sts/mex?wsdl the.osso.server:port/opensso/sts/soap11 the.osso.server:port/opensso/sts/soap11?wsdl with no luck. Thanks for your help, Tyler

• Custom MediaStreamSource and MediaElement.Naturalduration property

  - by Tilo Skomudek

  i have written a custom mediastreamsource, that can play media from growing source files (mpeg transport streams). Once it reaches the end of its mediastream, it reads the new duration from the mediafile and continues to deliver samples. The MediaElement plays continously. Unfortunately i haven´t found a way to update the MediaElement.NaturalDuration property. Hence i cannot seek into the “reloaded” area, because ME doesn´t know about it and sets my position change to its NaturalDuration value. I tried to call ReportOpenMediaCompleted after getting the new stream length. Then Naturalduration get´s updated, but i cannot play anymore. Is there any other way to deal with it ?

• Python Naming Conventions for Dictionaries/Maps/Hashes

  - by pokstad

  While other questions have tackled the broader category of sequences and modules, I ask this very specific question: "What naming convention do you use for dictionaries and why?" Some naming convention samples I have been considering: # 'value' is the data type stored in the map, while 'key' is the type of key value_for_key={key1:value1, key2,value2} value_key={key1:value1, key2,value2} v_value_k_key={key1:value1, key2,value2} Don't bother answering the 'why' with "because my work tells me to", not very helpful. The reason driving the choice is more important. Are there any other good considerations for a dictionary naming convention aside from readability?

• Cassandra and asp.net (C#)

  - by Sergey Osypchuk

  I am interested to create portal on cassandra services, since I faced some performance and scale issues starting from 1 million of records. Definitely, it could be solved, but I am interested on other options. My main issues is cost of updating all necessary indexes, to make reading fast. First, is cassandra is good way for asp.net programmers? I mean, maybe there is some other projects, which worth to take a look And second, can you provide any documentation samples on how to start with cassandra programming from C#?

• Editing Data in Child Window with RIA Services and Silverlight 4

  - by Rick Arthur

  Is it possible to edit data in a SilverLight Child window when using RIA Services and Silverlight 4? It sounds like a simple enough question, but I have not been able to get any combination of scenarios to work. Simply put, I am viewing data in a grid that was populated through a DomainDataSource. Instead of editing the data on the same screen (this is the pattern that ALL of the Microsoft samples seem to use), I want to open a child window, edit the data and return. Surely this is a common design pattern. If anyone knows of a sample out there that uses this pattern, a link would be much appreciated. Thanks, Rick Arthur

• LibraryContainer in a ScatterViewItem: resizing and background rectangle...

  - by Rob Fleming

  Simple one: Want to add a LibraryContainer to a Surface ScatterView. Know I have to add the container inside a ScatterViewItem to get the rotate/move features.. but the SVI adds a rectangle box around the control, and it does not size correctly. Think I'm missing something simple but can't figure it... My current XAML is as follows: Background="{StaticResource WindowBackground}" AllowDrop="True" . . . Any thoughts are appreciated... I've been looking at the how-to samples but the library controls that are shown are static item. (ie they are not movable)... Rob

• x264 IDR access unit with a SPS and a PPS

  - by Gcoop

  Hi All, I am trying to encode video in h.264 that when split with Apples HTTP Live Streaming tools media file segmenter will pass the media file validator I am getting two errors on the split MPEG-TS file WARNING: Media segment contains a video track but does not contain any IDR access unit with a SPS and a PPS. WARNING: 7 samples (17.073 %) do not have timestamps in track 257 (avc1). After hours of research I think the "IDR" warning relates to not having keyframes in the right place on the segmented MPEG-TS file so in my ffmpeg command I set -keyint_min 1 to ensure keyframes where at every frame, but this didn't work. Although it would be great to get an answer, if anyone can shed any light on what a "IDR access unit with a SPS and a PPS" is or what the timestamps warning means I would be very grateful, thanks.

• Store and retrieve images from file system instead of database

  - by Karsten

  Hi I need a place to store images. My first thought was to use the database, but many seems to recommend using the filesystem. This seems to fit my case, but how do I implement it? The filenames need to be unique, how to do that. Should I use a guid? How to retrieve the files, should I go directly to the database using the filename, make a aspx page and passing either filename or primary key as a querystring and then read the file. What about client side caching, is that enabled when using a page like image.aspx?id=123 ? How do I delete the files, when the associated record is deleted? I guess there are many other things that I still haven't thought about. Links, samples and guidelines are very welcome!

• .NET ThreadPool QueueUserWorkItem Synchronization

  - by ikurtz

  I am employing ThreadPool.QueueUserWorkItem to play some sound files and not hanging up the GUI while doing so. It is working but has an undesirable side effect. While the QueueUserWorkItem CallBack Proc is being executed there is nothing to stop it from starting a new thread. This causes the samples in the threads to overlap. How can I make it so that it waits for the already running thread to finish running and only then run the next request? EDIT: I did: Thread t = new Thread(FireAttackProc(fireResult)); t.Start(); but it gave me some errors. How do I specify a thread method with parameters?

• WF4 - Display workflow design in asp.net and highlight an activity

  - by jikan_the_useless

  i need to display current status of a document approval workflow task in asp.net web page with a specific activity highlighted. i have seen the visual workflow tracker example (in wf&wcf samples) but i have two issues, 1-i have to render workflow in asp.net not in a wpf app. 2-i don't need to display current status with workflow running, all activities that need to highlighted are the one that require user input. e.g. "waiting for approval from department head" etc. if i could just convert the workflow xaml to jpg after highlighting a specific activity by activity id that created a bookmark and waiting to resume the bookmark it would do the work.

• Figuring if a link is clicked on a webView - iPhone

  - by Uygar

  Hi, I am using a custom webview to show a tabbar when user touches on the webview. But when I clicked on a link in a webview, tabbar is shown for a little time and then page loads. I am using this custom webview to detect touch: http://github.com/psychs/iphone-samples/blob/b772b963f2acf18d478b41b44555992fcd8d4f31/WebViewTappingHack/Classes/PSWebView.m Can I detect if a link clicked or not? Because a link stands on the webview, webview detects the touch and also it loads the page... I want to prevent it. Thanks in advance.

• Interacting with google docs after logging into my google market apps - how

  - by Ali

  Hi guys I have a google apps account set up and even set up a simple hello world application from the available samples on the tutorial however I need to set it so I am able to interact with the google docs account associated with the account which has added my application. To interact with google docs I am aware that a token is requested from google upon authentication and verification of the account however that is in a situation where you code specifically for interacting with google docs - I'm talking about having access to the google docs of the account which has added my application so my application can be used to upload documents to the google docs and make references to them - basically my application is a resource management application and it needs to be able to store references to google docs.

• java enterprise project

  - by darko petreski

  Hi All, All the time we are hearing that java is enterprise. We have read many books about jpa, entity beans and other stuff. All this books explain this technology with some dummy examples. I have not seen a book that explains real problems with enterprise beans, java clients and security! I mean real book not some imaginated stupid examples . Is there any book that describes completely some enterprise system, Its architecture, communication, security, of course the client that uses the distributed components ? I need a book that will cover the flowing: server side components (ejb, jpa) client side java desktop application security (authentication and authorization) web services with complete authentication clustering (we can find for all of this a book, but there is no book that covers all this things in one piece. Also all the books are with dummy samples.) Or may be some project that is documented. Regards, Darko

• Lua pattern matching vs. regular expressions

  - by harald

  hello, i'm currently learning lua. regarding pattern-matching in lua i found the following sentence in the lua documentation on lua.org: Nevertheless, pattern matching in Lua is a powerful tool and includes some features that are difficult to match with standard POSIX implementations. as i'm familiar with posix regular expressions i would like to know if there are any common samples where lua pattern matching is "better" compared to regular expression -- or did i misinterpret the sentence? and if there are any common examples: why is any of pattern-matching vs. regular expressions better suited? thanks very much, harald
