  • Custom Validator with an OR Condition

    - by zSysop
    Hi all, Right now i have an asp.net 2.0 app which allows a user to search by the following fields Location (Required if there is nothing in idnumber field) Address (Required if there is nothing in idnumber field) Zip (Required if there is nothing in idnumber field) **OR** IDNumber. (Required if there is nothing in any of the other fields) What i'd like to be able to do is validate this client side on button click and display a summary of errors. i.e. if a user leaves every criteria blank. I'd like to display "You must enter a IDNumber or "Location, Address, and Zip to continue" I've never used the Custom Validation control so here are some questions. 1) Is it able to do this? 2) Does anyone have an example of how to do this? Thanks

  • Avoiding cookies while requesting static content

    - by Abdel Olakara
    I just did an audit of one of my web application page (built using ASP.Net and running on development server) using Google chrome's developer tool. One particular warning caught my eyes: Serve static content from a cookieless domain (5)! Here is my screen shot (http://yfrog.com/7eauditresultp) as well. I would like to know is it possible to avoid cookies for these kind of requests. I see that there is no cookie requests for javascript files as well. I it possible to avoid cookies in the header for these files as well? and why didn't the browser attach cookies for javascript files and attach for CSS and image? Any thoughts and suggestions are welcome

  • MSSQL Search Proper Names Full Text Index vs LIKE + SOUNDEX

    - by Matthew Talbert
    I have a database of names of people that has (currently) 35 million rows. I need to know what is the best method for quickly searching these names. The current system (not designed by me), simply has the first and last name columns indexed and uses "LIKE" queries with the additional option of using SOUNDEX (though I'm not sure this is actually used much). Performance has always been a problem with this system, and so currently the searches are limited to 200 results (which still takes too long to run). So, I have a few questions: Does full text index work well for proper names? If so, what is the best way to query proper names? (CONTAINS, FREETEXT, etc) Is there some other system (like Lucene.net) that would be better? Just for reference, I'm using Fluent NHibernate for data access, so methods that work will with that will be preferred. I'm using MS SQL 2008 currently.

  • Does the chunk of the System.Collections.Concurrent.Partitioner need to be thread safe?

    - by Scott Chamberlain
    I am working with the Parallel libraries in .net 4 and I am creating a Partitioner and the example shown in the MSDN only has a chunk size of 1 (every time a new result is retrieved it hits the data source instead of the local cache. The version I am writing will pull 10000 SQL rows at a time then feed the rows from the cache until it is empty then pull another batch. Each partition in the Partitioner has its own chunk. I know every time I call to the IEnumerator in from the SQL data-source that needs to be thread safe but for use in a Parallel.ForEach do I need to make every call to the cache for the chunking thread safe?

  • How to get Screen Shot / Screen Capture from Web user on MVC site?

    - by RSolberg
    I've seen a few different apps that allow users to take screen shots on their PC and then the utility will automatically upload the image to the web server. I'd like to incorporate this type of functionality into a new MVC site. I could certainly just allow the user to upload their own image, but it'd be cleaner if they could click Capture Screen Shot and the image would be uploaded automatically. My team is using ASP.NET MVC2 with a SQL back end database. We are certainly willing to look into 3rd party components (activeX based, etc.) that will allow us to achieve this.

  • Subscribing to MSMQ over the internet

    - by Nathan Palmer
    I haven't been able to find a clear answer to this problem. Is there a good way to subscribe to a MSMQ through the internet? Ideally I need security both in authentication and encryption for this connection. But I would like the subscriber to act just like any other client that would be subscribed on the local network. I believe I have a couple of options here Expose the MSMQ ports publicly Put the MSMQ behind some type of WCF service (not sure if that works for a subscriber) What other options do I have? We're sitting in a .NET environment and the main problem domain that is trying to be solved is to change the remote connections from a pulling system to an event based system to reduce the load on the main server.

  • Voting software with remote units - architectural questions

    - by David Neale
    I'm looking at designing some software that registers live votes (let's say A,B,C or D). The vote needs to be picked up and processed by a .NET engine. The remote voting units should be as small as possible. What form of data transmission should be used for the voting? The data is obviously very simple but there is a need to make sure each unit can only vote once per question. How would the data be received by the computer running the software?

  • Does DataType DataAnnotation Check the Expression?

    - by Jason
    I am currently using DataAnnotations within my ASP.NET MVC website to ensure data is properly validated. One question I wanted to verify (I think I know the answer, but I can't find verification online) - does the DataType DataAnnotation perform regular expression checks to ensure that you have received a valid e-mail/phone/currency/etc? [Required(ErrorMessage = "Price required")] [DataType(DataType.Currency, ErrorMessage = "Not a valid price")] [Range(0, double.MaxValue, ErrorMessage = "Price must be greater than 0.")] public decimal Price { get; set; } I believe the answer is no (meaning I have to provide my own, custom, RegularExpressionAttribute), but I wanted to double check before I do that for various field types.

  • Run JavaScript after a DropDownList is DataBound

    - by Daniel Coffman
    I need to trigger a JavaScript function to be called AFTER a DropDownList on my ASP.NET WebForms page is DataBound, because the SelectedIndex of this DropDownList is the parameter to the JavaScript function. I've tried this various ways, but it seems that if I do it with pure JavaScript onload by using ClientScript.RegisterStartUpScript, the control can be found (because it hasn't been assigned a clientID yet?). If I use jQuery (document).ready { } it says that the DropDownList has no selectedIndex.value. So I need some JavaScript to run AFTER the control has a value set by the DataBind. How can I accomplish this? onChanged won't work because I need the function to fire on the first page load, with no user input. DataBinding the SelectedIndex of the DropDownList doesn't cause the JavaScript onChanged event to fire.

  • Are there any small scale, durable document/object databases?

    - by Joe Doyle
    I have a few .Net projects that would benefit from using a document/object database opposed to a relational one. I think that db4o would be a good choice, but we're not sure how much the cost is. I'd love to use MongoDB but it's design isn't for small scale, single server applications. Are there other options out there that I just haven't run across for small scale applications? EDIT: So is this a space that doesn't have a good solution, yet? Are there no small scale & durable document databases? Would my best choice be to use MongoDB and set the --syncdelay option set to 1?

  • Build Machine Configuration Recommendations?

    - by IPX Ares
    We have a new build machine to start using for our programming team. We are still trying to figure out how we want to organize everything to get the best configuration for building EXEs and DLLs. We are using VB6 and VB.Net 2005, and VSS2005. We were thinking of making working folders set for each project, release and support tickets. Does anyone have experience with a similar set up? What were your likes/dislikes? Any recommendations (New VSS IDs, folder configuration, setting working folder, updating/building files)?

  • Can managed and unmanaged C++/MFC be mixed in one dll?

    - by Walter Williams
    Previously we had software in MFC (VC6), VB6 and C# applications that needed to call the same engine written in C++ (and MFC). The engine required C++ for speed. At the time we decided to use COM as the interface because all three could use it with the least issues in marshalling, etc. Our MFC application is now deprecated and we have recently decided to dump VB6, so what we've got left is C#. We can just leave the COM engine as-is, but it would be nice to get away from COM registration, etc., and have a managed interface to work with. COM registration occasionally causes support issues if there is something wrong with the person's machine. Is it possible to have a dll with the existing unmanaged C++/MFC, and a .NET front end interface?

  • Prevent query string manipulation by adding a hash?

    - by saille
    To protect a web application from query string manipulation, I was considering adding a query string parameter to every url which stores a SHA1 hash of all the other query string parameters & values, then validating against the hash on every request. Does this method provide strong protection against user manipulation of query string values? Are there any other downsides/side-effects to doing this? I am not particularly concerned about the 'ugly' urls for this private web application. Url's will still be 'bookmarkable' as the hash will always be the same for the same query string arguments. This is an ASP.NET application.

  • C#, weird optimization

    - by Snake
    Hi, I'm trying to read my compiled C# code. this is my code: using(OleDbCommand insertCommand = new OleDbCommand("...", connection)) { // do super stuff } But! We all know that a using gets translated to this: { OleDbCommand insertCommand = new OleDbCommand("...", connection) try { //do super stuff } finally { if(insertCommand != null) ((IDisposable)insertCommand).Dispose(); } } (since OleDbCommand is a reference type). But when I decompile my assembly (compiled with .NET 2.0) I get this in Resharper: try { insertCommand = new OleDbCommand("", connection); Label_0017: try { //do super stuff } finally { Label_0111: if ((insertCommand == null) != null) { goto Label_0122; } insertCommand.Dispose(); Label_0122:; } I'm talking about this line: if ((insertCommand == null) != null). True is not null, it never is, nor is false. So how is my object disposed properly? WTF? Thanks! -Kristof

  • C# Proxy using Sockets, how should I do this?

    - by Kin
    I'm writing a proxy using .NET and C#. I haven't done much Socket programming, and I am not sure the best way to go about it. What would be the best way to implement this? Should I use Synchronous Sockets, Asynchronous sockets? Please help! It must... Accept Connections from the client on two different ports, and be able to receive data on both ports at the same time. Connect to the server on two different ports, and be able to send data on both ports as the same time. Immediately connect to the server and start forwarding packets as soon as a client connection is made. Forward packets in the same order they were received. Be as low latency as possible. I don't need the ability for multiple clients to connect to the proxy, but it would be a nice feature if its easy to implement. Client --------- Proxy ------- Server ---|-----------------|----------------| Port <-------- Port <------- Port Port <-------- Port <------- Port

  • See if any application has a DLL from the GAC loaded

    - by rwmnau
    I'm trying to deploy new copies of my DLL to the GAC on remote servers, but I need to identify if any processes currently running have a loaded copy of the DLL I'm replacing - I'd like to restart them, or at least tell the user. For example, Biztalk seems to load the DLLs it needs the first time they're used, and then replacing them keeps the old copy in memory until the Host Instances are restarted - something I could easily do as part of my deployment. Is there a way to tell using .NET which processes have loaded a particular DLL from the GAC? UPDATE: Some further investigation shows that both Process Explorer has this functionality, and another Sysinternals tool, ListDLL, does exactly what I want to be able to do. I'd like to know how they do it, since I'd love to replicate this functionality in my application without having to include and screen-scrape ListDLL (if that's even allowed inside the license).

  • I don't understand Application Domains

    - by Jeremy Edwards
    .NET has this concept of Application Domains which from what I understand can be used to load an assembly into memory. I've done some research on Application Domains as well as go to my local book store for some additional knowledge on this subject matter but it seems very scarce. All I know that I can do with Application Domains is to load assemblies in memory and I can unload them when I want. What are the capabilities other that I have mentioned of Application Domains? Do Threads respect Application Domains boundaries? Are there any drawbacks from loading Assemblies in different Application Domains other than the main Application Domains beyond performance of communication? Links to resources that discuss Application Domains would be nice as well. I've already checked out MSDN which doesn't have that much information about them.

    hey all, I have to make a SMS sending application in .NET, which uses the attached Blackberry handset(blackberry tour 9630 to be precise) to send SMS. I have never worked on smartphone application development, so want help in doing this. I searched SO for an answer and found one question, but its in java and i think that code would run on blackberry itself and not on desktop, correct me if i am wrong. So if someone could point me in the right direction I would be very grateful. Thanks in advance to all those who reply.

  • What is the equivalent to IScriptControl for Web.UI.Page?

    - by Jeff Dege
    We've been using IScriptControl to tie javascript objects to our UserControls and ServerControls, and it's worked fine. The problem is that ASP.NET seems to provide no method to tie a javascript object to a Page. Up to now, we've been putting plain functions in the global namespace, but I am developing a serious allergy to that practice. It'd be easy enough to wrap our functions into a javascript class, and to include the javascript file on the page, but how to instantiate the object, how to reference it from callback events, and how to pass data to it from the code-behind, I haven't figured out. Or rather, the methods we've been using up to now (hidden fields, emitted javascript strings, etc.), really bug me. Anyone have better ideas?
