• Passing Data from Usercontrol to controller

  - by nitinkhanna

  Hi, I am new to MVC, and trying something and got stuck somewhere in between. I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like <input type="button" value="Search" onclick="location.href='<%= Url.Action("action", "controller") %>'" /> I have called this usercontrol on some view through <%= Html.Partial("ucName") %> Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid. I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.

• Improve this snippet from a prototype class

  - by seengee

  This is a snippet from a prototype class i am putting together. The scoping workaround feels a little hacky to me, can it be improved or done differently? var myClass = Class.create({ initialize: function() { $('formid').getElements().each(function(el){ $(el).observe("blur", function(){ this.validateEl(el); }.bind(this,el)); },this); }, validateEl: function(el){ // validate $(el) in here... } }); Also, it seems to me that i could be doing something like this for the event observers: $('formid').getElements().invoke("observe","blur" ... Not sure how i would pass the element references in though?

  - by Anish

  Hi , I have a button control in my wpf-mvvm application. I use an ICommand property (defined in viewmodel) to bind the button click event to viewmodel.

• how to get an instance of an XMLEventAllocator?

  - by kostja

  I am trying to follow the recommended way of parsing XML with StAX using sun's Cursor-to-Event Example for Java EE 5. You are supposed to traverse the XML via the Cursor API and allocate an XMLEventusing an XMLEventAllocator when necessary. Awkwardly, sun's own example does not compile (at least not with JDK 1.6, even with 1.5 code compliance). The example tries to instantiate an allocator via new, but the according implementation classes in the JDK are not accessible externally. After reading the JavaDocs and searching the web I have found literally nothing. One could implement the XMLEventAllocator interface from scratch, but it seems really wrong, when there are perfectly good implementations in the JDK, besides not being an expert in StAX makes it difficult to get it right.

• DropDownList selectedValue not changing display

  - by MemphisDeveloper

  I have a list of controls that I change based on an event. The controls are contained within a table that is created dynamically. I traverse through a set of controls and if it is a RadioButtonList or a DropDownList I do the following: CType(cntrl, ListControl).SelectedValue = val The radio buttons set just fine but the dropdown list doesn't reset. Can anyone tell me why. The initial table is created on the first Page Load and stored in memory. It's values are changed during the eventhandling and reposted to a MasterPage's content holder.

• Parse both symbols . and , as decimal digits delimiter in ASP.NET

  - by abatishchev

  I'm writing a banking system and my customer wants support both Russian and American numeric standards in decimal digits delimiter. Respectively . and ,. Now only , works properly. Perhaps because of web server's OS format (Russian is set). String like 2000.00 throws a FormatException: Input string was not in a correct format. How to fix that? Are there any other ideas except String.Replace('.', ',') on FormView.ItemInserting event?

• How to run an SQL stored procedure through C# at a specific time?

  - by yishai neeman

  I am building a website now for a library and i need to check every day at the same time if there are people who need to return their books in the next five days and to send them a reminder via email. My question is what will be the correct way to do that? What i need to accomplish is when the specific time of day comes i need to run an sql stored procedure and check either through visual studio 2010 or any other way if the stored procedure has returned any results to which i need to email. Is there a way to maybe check the system time constantly on C# and not as a triggered event?

• How do I close a form when the ESC key was hit, but only if no Control handled it?

  - by Gabriel

  I have a Form that closes itself when the ESC key is pressed, thanks to KeyPreview, ProcessKeyEventArgs, ProcessCmdKey or whatever. But I have a Control on that form that does very relevant things when ESC is pressed (it hides itself) and the Form should not be closed when that happens. The control uses the KeyDown event and sets the SuppressKeyPress flag to true, but that happens after the aforementioned form key preview, thus having no effect. Is there some sort KeyPostview ? How do I not close the form when a Control has a relevant use of a key hit ? Edit: The control handling ESC is a textbox embedded in a hand-maid ListView. The textbox appears when the user clicks a cell, enabling edition. To validate the new text, ENTER would be nice (that already works, as giving the focus to anything else). To cancel edition, ESC seems most natural.

• Why do my WPF UIElements NOT have OnPreview events?

  - by Matt.M

  I'm building a custom Silverlight UserControl which needs to listen to events using Preview/Tunneling, but for some reason the compiler is telling me they are not recognized or accessible. For example, I can add an event handler to MouseLeftButtonDown, but not PreviewMouseLeftButtonDown. This doesn't make sense because according to Microsoft (http://msdn.microsoft.com/en-us/library/system.windows.uielement_members(v=VS.100).aspx) all UIElements should have Preview events attached. Any ideas as to why this is happening? I'm using Visual Studio 2010 Trial, Blend 4 RC and .Net 4, if that makes a difference.

• OpenSSH connection trouble

  - by gnostical

  Hi, I'm trying to use Putty 0.60 to log in to an OpenSSH 5.3 server. Connections with openssh from another Linux server are possible, but Putty fails. Putty's event log tells me "software caused connection abort" right after the DH key exchange, the server log doesn't report anything (set to INFO). I analyzed the traffic with Wireshark and got a whole bunch of "TCP retransmission" and "TCP DUP ACK" after said key exchange. Sometimes I was able to log in, but at some point (usually < 2 min.) the connection froze without any logged messages. Sadly, I didn't capture a trace. The server is my own (Funtoo with genkernel and gentoo-sources 2.6.34), so I may tweak it, but I'd still like to know what causes the error. Any suggestions? Thank you!

• Auto save changed text in richtextbox to database

  - by user2519407

  I have created one simple note taking application in jquery & php. Current functionality is like when user clicks save button it sends a ajax request with complete data to update it in db(mysql). All works well. But now I want to auto save only changed text while user typing. I don't want to send entire text to server again and again in text change event. It should send only text which has changed. For Ex: This is saved text. When user continues typing. This is saved text. Unsaved text.. It should be able to send only "Unsaved text.." to server to update in db. How can i implement this in jquery & server side script.? Any Idea..?

  - by Rahat

  Is there any way to capture the time interval between mouse wheel scroll start and stop? Actually I want to capture the interval between the scrolling start and stop when I very quickly scroll the mouse wheel. I have already looked at MouseWheel event but it don't fulfill my requirement. In senes that it always gives a value of Delta 120 or -120 but i want to call a function depending on the speed of the mouse scroll for example when i scroll the mouse normally i want to perform function 1 and when i scrolled the mouse very quickly i want to perform the function 2. In other words is there any way to distinguish between the mouse scroll high and normal speed. Any advice will be appreciated.

• assistance with fxcop

  - by amateur

  I am at present developing a mvc4 project that comunicates to a set of wcf services. I am setting such up in tfs build for a team of developers. I am very much a newbie to fxcop and code analysis in general. I am currently researching it and have some questions following this: Is it recommended to use the rules that come with fxcop? Should it be included as a build task during builds? What is the value from it? Are there guidelines to what rules to abide by or is it best to go with the default? Is it correct to run the analysis as a post build event? I am a newbie to fxcop and would like some feedback. I am as it is integrating stylecop in to my build.

• Bind jQuery UI autocomplete using .live()

  - by seth.vargo

  I've searched everywhere, but I can't seem to find any help... I have some textboxes that are created dynamically via JS, so I need to bind all of their classes to an autocomplete. As a result, I need to use the new .live() option. As an example, to bind all items with a class of .foo now and future created: $('.foo').live('click', function(){ alert('clicked'); }); It takes (and behaves) the same as .bind(). However, I want to bind an autocomplete... This doesn't work: $('.foo').live('autocomplete', function(event, ui){ source: 'url.php' // (surpressed other arguments) }); How can I use .live() to bind autocomplete? UPDATE Figured it out with Framer: $(function(){ $('.search').live('keyup.autocomplete', function(){ $(this).autocomplete({ source : 'url.php' }); }); });

• Creating C# form fields with events based off of a text file

  - by evolve

  I need to generate windows form fields based off of a text file that I am parsing. I also want to automatically generate validation event handlers which all will be basically the same only the form field and the regular expression which is used to validate the field will change. I'm having a difficult time figuring out the quickest and easiest method to go about doing this. Any pointers in the right direction would really be great, maybe even some keywords that I'm missing. I can only imagine this type of question has been covered before, I just don't know what I'm searching for really.

• Actionscript Receiving Mouse Events For Lower Indexed And Partially Covered Display Objects?

  - by Chunk1978

  i have 2 sprites on stage. bottomSprite is added to the display list first, followed by topSprite. topSprite partially covers bottomSprite. i've added an event listener to bottomSprite for MouseEvent.MOUSE_MOVED notifications to simply trace the mouseX and mouseY coordinates. however, the notification doesn't work for the parts of bottomSprite that are covered by topSprite. var bottomSprite:Sprite = new Sprite(); bottomSprite.graphics.beginFill(0x666666, 0.5); bottomSprite.graphics.drawRect(150,150, 150, 150); bottomSprite.graphics.endFill(); addChild(bottomSprite); var topSprite:Sprite = new Sprite(); topSprite.graphics.beginFill(0x00FFFF, 0.5); topSprite.graphics.drawRect(250,50, 150, 150); topSprite.graphics.endFill(); addChild(topSprite); bottomSprite.addEventListener(MouseEvent.MOUSE_MOVE, traceCoords); function traceCoords(evt:MouseEvent):void { trace ("Coord = X:" + bottomSprite.mouseX + ", Y:" + bottomSprite.mouseY); }

• Downloading HTTP URLs asynchronously in C++

  - by Joey Adams

  What's a good way to download HTTP URLs (e.g. such as http://0.0.0.0/foo.htm ) in C++ on Linux ? I strongly prefer something asynchronous. My program will have an event loop that repeatedly initiates multiple (very small) downloads and acts on them when they finish (either by polling or being notified somehow). I would rather not have to spawn multiple threads/processes to accomplish this. That shouldn't be necessary. Should I look into libraries like libcurl? I suppose I could implement it manually with non-blocking TCP sockets and select() calls, but that would likely be less convenient.

• How to get original url after HttpContext.RewritePath() has been called.

  - by jessegavin

  I am working on a web app which makes use of a 3rd party HttpModule that performs url rewriting. I want to know if there's any way to determine the original url later on in Application_BeginRequest event. For example... Original url: http://domain.com/products/cool-hat.aspx Re-written url (from 3rd party httpmodule): http://domain.com/products.aspx?productId=123 In the past I have written HttpModules that store the original url in HttpContext.Items but, this is a 3rd party app and I have no way of doing that. Any ideas would be appreciated.

• Rsspnse.redirect will not redirect on Internet explorer

  - by Amit

  Hi, I am using Response.Redirect("someurl",true); in the page_preInit event to redirect all the requests that come to a page. It works fine on Firexox, but if i access the page from internet explorer 7/8, it says page can not be found and will not redirect to new URL. Any idea why this happens?? Update: I tried giving a radom URL in the redirect such as google.com and it works fine. Actually the URL I am trying to redirect is not accessible on my machine, it is on another VPN. I guess IE will not change the URL on the addressbar if it can not access the URL. Firefox on the other hand changes the address on the address bar.

• Tree View / File View Control for C#

I don't always want to start at a "default" top directory level. The ability to grab an event when the user double clicks on a file in the tree. I want to handle opening the file within my application. I have been looking at this C# File Browser. Unfortunately, I have not been able to figure out how to do meet my second need. (If anybody can clear that up for me, I would like that even better.) Thanks for any help.

• Breakpoint when variable takes on a certain value.

  - by Mick

  I have something analogous to the following code... void function(int x) { // complicated operation on x blah blah } It all appears to be working fine except when x happens to be a particular value, say "273". But x being 273 is a rare event, 99.999% of the time it is some other value. Now I wish to observe the events when this function is called with x=273, so I would like to insert a breakpoint that gets hit only with x is that value. Perhaps I could do it like this: void function(int x) { if (x == 273) { // put breakpoint on this line. } // complicated operation on x blah blah } The problem is that presumably the compiler will optimise away this "if" statement because it doesn't do anything. So my question is what should I put within the "if" statement to to make sure it gets compiled in to something... or should I be tracing the x==273 case in some completely different way.
