• How to create a custom ADO Multi Dimensional Catalog with no database

  - by Alan Clark

  Does anyone know of an example of how to dynamically define and build ADO MD (ActiveX Data Objects Multidimensional) catalogs and cube definitions with a set of data other than a database? Background: we have a huge amount of data in our application that we export to a database and then query using the usual SQL joins, groups, sums etc to produce reports. The data in the application is originally in objects and arrays. The problem is the amount of data is so large the export can take 2 hours. So I am trying to figure out a good way of querying the objects in memory, either by a custom OLAP algorithm or library, or ADO MD. But I haven't been able to find an example of using ADO MD without a database behind it. We are using Delphi 2010 so would use ADO ActiveX but I imagine the ADO.NET MD is similar. I realize that if the application data was already stored in a database the problem would solve itself. Also if Delphi had LINQ capability I could query the objects and arrays that way.

• Good way to find duplicate files?

  - by OverTheRainbow

  Hello I don't know enough about VB.Net (2008, Express Edition) yet, so I wanted to ask if there were a better way to find files with different names but the same contents, ie. duplicates. In the following code, I use GetFiles() to retrieve all the files in a given directory, and for each file, use MD5 to hash its contents, check if this value already lives in a dictionary: If yes, it's a duplicate and I'll delete it; If not, I add this filename/hashvalue into the dictionary for later: 'Get all files from directory Dim currfile As String For Each currfile In Directory.GetFiles("C:\MyFiles\", "File.*") 'Check if hashing already found as value, ie. duplicate If StoreItem.ContainsValue(ReadFileMD5(currfile)) Then 'Delete duplicate 'This hashing not yet found in dictionary -> add it Else StoreItem.Add(currfile, ReadFileMD5(currfile)) End If Next Is this a good way to solve the issue of finding duplicates, or is there a better way I should know about? Thank you.

• Is there a Windows API to modify file type associations for an extension?

  - by JohnFx

  I'm looking for a way to programatically tweak the particulars of a file association on a Windows system. For example, the "Application User to Perform this Action" setting for the "Open" action for a particular file type. Clearly I could do this by modifying the registry directly, but if there is an API I'd prefer to use that as it would likely be more resilient to changes in the OS handling of mapping extensions to applications. For my purposes I'm needing to write this in VBScript (.VBS) file because it is part of a package to be used with VMWare ThinApp that mandates it. However, I'll port/wrap/whatever I need to make this week, so I am open to any solution (including using the .NET framework)

• jsTree causes that links on whole page are broken

  - by niao

  Greetings, I have the following problem. In my asp.net mvc page (which is a partial view) I create an instance of jsTree as follows: <script type="text/javascript"> $(function() { $("#industries").tree({ callback: { onselect: function(NODE, TREE_OBJ) { $("#SelectedIndustryROWGUID").val($(NODE).attr("id")); $("#resultMessage").append($(NODE).attr("rel")); } }, data: { type: "json", async: true, opts: { method: "GET", url: "/CreateMessage/GetIndustries/" } } }); }); this works fine but then, when I click on any link on the page, it does not work. The links are executed when I choose "open in new tab" option from context menu. Can someone please help me with this?

• How to allow users to customize a DAL

  - by rsteckly

  Hi, I'm working in ASP.NET in an application where often users want to add fields or change field names. I'd like to be able to have an xml schema in place that is parsed and a dynamic object model created from it that can be accessed throughout the application. My initial reaction is that this is not realistic. I think there is flexibility about the dynamic nature of it. I think the people I'm trying to build this for wouldn't mind recompiling. Even if the app recompiled, I don't know how to abstract away enough in my code access the data to allow for users changing property names, etc. How can you write LINQ when the properties might change? In short, there's two questions here: 1) is there a way to dynamically generate an object model of the database and 2) is there a way to abstract away enough so that code accessing the database doesn't break when properties change?

• DropdownList autoposback after client confirmation

  - by Aamir

  I have a dropdownlist with the autopostback set to true. I want the user to confirm if they really want to change the value, which on post back fires a server side event (selectedindexchanged). I have tried adding an onchange attribute "return confirm('Please click OK to change. Otherwise click CANCEL?';") but it will not postback regardless of the confirm result and the value in the list does not revert back if cancel selected. When I remove the onchange attribute from the DropdownList tag, the page does postback. It does not when the onchange attribute is added. Do I still need to wire the event handler (I'm on C# .Net 2.0 ). Any leads will be helpful. Thanks!

• Secondary Domain Adds Extra Folder in URL during Postbacks

  - by Joshua

  My ASP.NET Website (C#, 3.5 framework, IIS7) is hosted at GoDaddy. There are multiple sites on the account. Currently when I perform postbacks or Response.Redirects on a secondary web site, the following URL appears in the address bar: www.mywebsite.com/webfolder/default.aspx Where the "webfolder" is the sub-directory on the server where the web site is hosted (i.e. SeverRoot/webfolder). The site seems to work with or without the folder in the URL. Is there a way to remove the folder from the URLs during postback? I think I have to use URL Rewriting (which GoDaddy supports using Microsoft's Rewrite Module) but I'm not sure how.

• WCF - Dynamically Change WebResponseFormat

  - by Brandon

  Is there a way to dynamically change the WebResponseFormat on a method given a parameter passed by the client? I default my WebResponseFormat to XML, but I want to give the client the opportunity to specify a format as JSON or XML and if none is specified, default to XML. Currently I am doing the following: [WebGet(UriTemplate = "objects", BodyStyle = WebMessageBodyStyle.Bare)] [OperationContract] List<SampleObject> GetObjects(); The user can call it via: http://localhost/rest/myservice/objects They then can specify a format by doing: http://localhost/rest/myservice/objects?format=json The problem is that when I try to set the response content type via: WebOperationContext.Current.OutgoingResponse.ContentType = "application/json"; That just returns the XML but the browser attempts to process it like a JSON object instead of serializing the response as JSON. Is this even possible with .NET 3.5 outside of using a Stream as the return value and serializing the response myself? If not, is there a better solution?

• IIS 7: Redirect all request to Default.aspx

  - by EtienneT

  We want to redirect all request in an ASP.NET site to ~/Default.aspx to close the site. We are using IIS7. The site has paths like this that return a page: http://test.com/operating We are using url rewriting. We want requests similar to those to be redirected to ~/Default.aspx http://test.com// http://test.com/.aspx http://test.com//.aspx We would normaly use something like this in web.config: <customErrors mode="On" defaultRedirect="Default.aspx"> <error statusCode="404" redirect="Default.aspx" /> </customErrors> The problem with this is that it won't redirect folder url like this http://test.com/*/ Thanks!

• Http 404: Not Found (WebException)

  - by Rajeev

  Hi, I am using a console app/class library to invoke a asp.net web service. The class library queries the database and sends the data to the web service. What I notice is that when the amount of data is huge (with 20 columns and 18K records), i get a HTTP 404: Not Found exception from the web service. I have tried increasing the maxReqeustLength and executionTimeout properties in the httpRuntime tag in the web.config of the web service. Is there any thing that I can do to overcome this? Thanks, Rajeev

• Default login popup for web sites

  - by John Quest

  Hi. I am trying to build a web site with ASP.NET MVC, I'm new to this. My question is: how can I display the default login dialog? I am not referring to a custom dialog, like the jQuery Dialog, there is a default pop-up for credentials, which looks different depending on browser, same as with javascript alert(), but I don't know how to display it. To know what I mean, go to http://fit.c2.com/wiki.cgi?WelcomeVisitors, there is a Login button at the bottom of the page, when you click it a pop-up appears. That is what I want to display. Any ideas?

• In-Proc SxS opens for shell extension in managed code?

  - by Jens Granlund

  The recommendation used to be "Do not write in-process shell extensions in managed code." But with .NET Framework 4 and In-Process Side-by-Side the main reason not to write shell extensions in managed code should be resolved. With that said, I have three questions. Is it now okay to write shell extensions in managed code? Which problems, if any might there be with writing shell extensions in managed code? What reasons might there be to write shell extensions in unmanaged code?

• Encrypting Files with AES, Encrypting Key with RSA - Am I on the right track?

  - by Shawn Steward

  Overview: I'm trying to design an application that will encrypt files to safely send through the mail. I'm planning on using AES/RijndaelManaged encryption from .Net to encrypt the files initially, using a randomly generated key using RNGCryptoServiceProvider. I'm then encrypting this random AES key with a RSA Public key. The receiver of the data is the only one with the RSA Private key to decrypt it. My question: Is this the proper way to do something like this? If so, is it safe to send this RSA-Encrypted key with the data since it requires the private key to decrypt? Also - when having the end user generate their Public/Private key pair, what is the best way to save the Private key? I do not want it to be only accessible from one machine, so I am trying to avoid using the user's key store. But MSDN says it is not safe to save the key to a file, so how else can you accomplish this?

• Capture and display console output at the same time

  - by Patrick

  Hi, MSDN states that it is possible in .NET to capture the output of a process and display it in the console window at the same time. Normally when you set StartInfo.RedirectStandardOutput = true; the console window stays blank. As the MSDN site doesn't provide a sample for this I was wondering if anyone would have a sample or could point me to a sample? When a Process writes text to its standard stream, that text is normally displayed on the console. By redirecting the StandardOutput stream, you can manipulate or suppress the output of a process. For example, you can filter the text, format it differently, or write the output to both the console and a designated log file. MSDN This post is similar to http://stackoverflow.com/questions/786726/capture-standard-output-and-still-display-it-in-the-console-window by the way. But that post didn't end up with a working sample. Thanks a lot, Patrick

• Filling data in FormView from different tables

  - by wacky_coder

  Hi, I am using a FormView in an online quiz page for displaying the questions and RadioButtons (for answers) http://stackoverflow.com/questions/2438219/online-quiz-using-asp-dot-net Now, I need to pick the questions according to a TestID and a particular Set of that Test. The testid and the set_number would be passed using Session variables. I'm having 3 testIDs and 3 Sets per TestID and, thus, am using 9 tables to store the Questions, the Options and the correct answer. I need help on how to set the FormView so that it extracts the questions from a particular table only. Do I need to use a StoredProcedure ? If yes, how? PS: If I use only one table to store all the questions from each Set and for each TestID, I can do that, but I'd prefer using separate tables.

• MVC DateTime binding with incorrect date format

  - by Sam Wessel

  Asp.net-MVC now allows for implicit binding of DateTime objects. I have an action along the lines of public ActionResult DoSomething(DateTime startDate) { ... } This successfully converts a string from an ajax call into a DateTime. However, we use the date format dd/MM/yyyy; MVC is converting to MM/dd/yyyy. For example, submitting a call to the action with a string '09/02/2009' results in a DateTime of '02/09/2009 00:00:00', or September 2nd in our local settings. I don't want to roll my own model binder for the sake of a date format. But it seems needless to have to change the action to accept a string and then use DateTime.Parse if MVC is capable of doing this for me. Is there any way to alter the date format used in the default model binder for DateTime? Shouldn't the default model binder use your localisation settings anyway?

• Google Checkout, OpenId, and downloadable products

  - by craigmoliver

  I going to use Google Checkout to process orders to purchase downloadable content. When the order process is completed via Google Checkout I'd like for the user to be able come back to my site, authenticate using their Google credentials (OpenID?) that they purchased the item with linked back end, and download the goods. The site is written using C# and ASP.NET MVC. Is this possible or how should I rethink this? Are there open-source libraries to get me started?

• Using Mapped Memory Files in C# to store reference types

  - by Khash

  I need to store a dictionary to a file as fast as possible. Both key and value are objects and not guaranteed to be marked as Serializable. Also I prefer a method faster than serializing thousands of objects. So I looked into Mapped Memory Files support in .NET 4. However, it seems MemoryMappedViewAccessor only allows storage of structs and not reference types. Is there a way of storing the memory used by a reference type of a file and reconstructing the object from that blob of memory (without binary serialization)?

• Bulkinsert from CSV into db (C#) -> max number of rows in a web application?

  - by Swoosh

  Web application - C#, .Net, SQL 2k5. I recently used bulkinsert on an other application and I thought I would like to give it a try. I am going to receive a CSV file with 1000 rows, which will most likely add 500 000 (that is five hundred thousand) records in the database. I don't have any idea yet about this huge amount if it's going to work out well. I am afraid that it will time out. I didn't do any testing yet, but I am pretty sure it would time out eventually. Is there a way to make it not time out (I don't know ... split the bulkinsert into 1000 pieces :D) or I should try to do something like BCP, with a SQL job ...

• Lucene search taking TOOO long.

  - by Josh Handel

  I;m using Lucene.net (2.9.2.2) on a (currently) 70Gig index.. I can do a fairly complicated search and get all the document IDs back in 1 ~ 2 seconds.. But to actually load up all the hits (about 700 thousand in my test queries) takes 5+ minutes. We aren't using lucene for UI, this is a datastore between processes where we have hundreds of millions of pre-cached data elements, and the part I am working on exports a few specific fields from each found document. (ergo, pagination doesn't make since as this is an export between processes). My question is what is the best way to get all of the documents in a search result? currently I am using a custom collector that does a get on the document (with a MapFieldSelector) as its collecting.. I've also tried iterating through the list after the collector has finished.. but that was even worse. I'm open to ideas :-). Thanks in advance.

• MC75 using symbol.imaging.device libraries for program

  - by Christy

  UPDATE: I found another library in the Windows Mobile - CameraCaptureDialog - this did the job - never did figure out the zero length available devices... Hi all, I have a .net application running on a symbol mc75 (motorola) using the scanner. I am now trying to add functionality for the camera and I am running into issues. To find the 'devices' you are supposed to use the library's 'available devices' function. With the barcode it is symbol.barcode.devices.availabledevices and it returns two items (you can scan from the scanner or using the camera device) However, when I do the camera library it does not find any devices - symbol.imaging.devices.availabledevices returns 0 I can take a picture using the software on the mc75, so I know the functionality is there, I just can't figure out how to get to it programmatically.... Does anyone have any ideas? Thanks for any help!

• Dynamically setting a log4net property using common.logging

  - by Kyle LeNeau

  Does anyone know if there is an equivalent in Common.Logging (for .Net) to set properties for the log4net factory adapter? I have had great success when just using log4net by doing: <appender name="FileAppender" type="log4net.Appender.RollingFileAppender"> <file type="log4net.Util.PatternString" value="logs\Log_%property{BrokerID}.txt"/> <appendToFile value="false"/> <rollingStyle value="Size"/> <maxSizeRollBackups value="-1"/> <maximumFileSize value="50GB"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date %-5level %logger - %message%newline"/> </layout> </appender> and setting the property like:log4net.GlobalContext.Properties["BrokerID"] = 10 The file I end up with the looks like this: Log_(null).txt when using the common.logging to wire up log4net on the fly.

• Neither IE or Firefox respects the control values that are output

  - by Luke Rohde

  I'm writing a survey designer asp.net mvc. It has buttons to move questions up and down. The buttons post the whole form back and the affected questions are swapped on the server. When the form returns the only thing that is changed are the values for each survey question. Both firefox and IE seem to ignore this change. Nothing is persisted to the database (until save) and url doesn't change so the post just returns the same view but I've stepped through my code to ensure the sequence of values being rendered in the view reflects the swap which is ok. However "view - source" doesn't show the change suggesting caching issue (maybe auto complete). I've tried autocomplete="off" in my form. Response.Cache.SetNoStore(); in my global.asax [System.Web.Mvc.OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")] before my controller and the following in my page header NOTHING!!! This must be real common. Anyone got a clue?
