  • ASP.NET custom server control: nested items

    - by Dylan Lin
    Hi, In the aspx code view, we can code like this: <asp:ListBox runat="server"> <asp:ListItem Text="Item1" /> <asp:ListItem Text="Item2" /> </asp:ListBox> However, the ListItem class is not a server control. How could we do that? Is there some attributes being consumed by the visual studio? Thanks:)

  • Styling a result set

    - by aepheus
    Perhaps this is not the proper place to ask this question, if that is the case, please direct me to the correct venue. I'm looking for research, guides, any kind of information pertaining to the structuring and styling of results sets; data which comes back from a search, or when looking at content in a list view. Links would be appreciated, but opinion and commentary are also valued.

  • access static class from asp.net form

    - by Eden
    I am using <%# MyFormatClass(Eval("fieldname")) % to display data in a grid view on my page. MyFormatClass works fine, but now I want to move it to a central location that can be used by many pages. When I try to access the class <%# Utils.MyFormatClass(Eval("fieldname")) % it no longer works. Is this something we are allowed to do?

  • Make iPad app a Universal app

    - by Peter Hajas
    I have an iPad app that I would like to make Universal, however this seems alarmingly difficult. I've changed things around so that I support both builds, but when building, I get lots of errors about using UIPopOvers. Here're my questions: Why does UI_USER_INTERFACE_IDIOM() not compile or register on 3.1.3? Can I conditionally have variables in a class definition based on UI_USER_INTERFACE_IDIOM()? If not, should I make two different view controllers? Thanks!

  • Should an NSLock instance be "global"?

    - by Alex Reynolds
    Should I make a single NSLock instance in the application delegate, to be used by all classes? Or is it advisable to have each class instantiate its own NSLock instance as needed? Would the locking work in the second case, if I, for example, had access to a managed object context that is spread across two view controllers?

  • jQuery multiple running totals

    - by Benjamin Randal
    0I am using jQuery to calculate a running total on multiple textboxes. Just found an awesome response on how to get that working a few days ago, but now I am running into another problem. When using one selector, the total for GetTotal is calculated perfectly. However, when I include the second selector, the totals begin to conflict with one another, and no longer calculate properly. I have been searching for a solution to this for some time now, does anyone have any ideas? Here is the selector i am currently using: function GetTotal(txtBox) { var total = 0; $('input:text').each(function(index, value) { total += parseInt($(value).val() || 0); }); $("#chkTotal").html(total); } My view uses these txt boxes <div class="editor-field"> @Html.TextBox("Field1", String.Empty, new {InputType = "text", id = "field1", onchange = "GetTotal(this)" }) </div> <div class="editor-field"> @Html.TextBox("Field2", String.Empty, new {InputType = "text", id = "field2", onchange = "GetTotal(this)" }) </div> <div> <h3>Total Checked</h3> </div> <div id="chkTotal"></div> Now I am trying to implement another selector which will total two additional editor fields... function GetTotal1(txtBox) { var total1 = 0; $('input:text').each(function (index, value) { total1 += parseInt($(value).val() || 0); }); $("#disTotal").html(total1); } View: <div class="editor-field"> @Html.TextBox("Field3", String.Empty, new {InputType = "text", id = "field3", onchange = "GetTotal1(this)" }) </div> <div class="editor-field"> @Html.TextBox("Field4", String.Empty, new {InputType = "text", id = "field4", onchange = "GetTotal1(this)" }) </div> <div> <h3>Total Distributed</h3> </div> <div id="disTotal"></div>

  • ER Data Model - confused by diagram.

    - by Khou
    Hi im a little confused by this diagram http://www.b-eye-network.com/images/content/i030ht0104.gif (Last diagram in the article) 1 - In the "ACCOUNTING ENTRY" table it shows "DebitEntry" and "CreditEntry" i) is this two column or ii) is this two rows of data? or iii) is it two separate tables on its own, Acounting_entry_credit and Accounting_entry_debit? Same question with the "ACCOUNT" table, it shows asset account, livabilities account, equaity account? are they 3 columns or are they 3 rows? Source: http://www.tdan.com/view-articles/5227/

  • Are there existing web sites that use a photo as a electronic signature?

    - by Alessandro Vernet
    The use case: to sign a electronic document, users view the document, and if they agree take a picture of themselves with their webcam (done through Flash from the browser). Then a PDF is generated containing the document and the picture in place of signature. This is a biometric signature, which is not as strong as a digital (cryptographic) signature, but stronger than having users draw their signature, as a photo is harder to forge than a drawn signature. Has anyone seen this technique being used on an existing web site?

  • How to locally test Django's Sites Framework

    - by Off Rhoden
    Django has the sites framework to support multiple web site hosting from a single Django installation. EDIT (below is an incorrect assumption of the system) I understand that middleware sets the settings.SITE_ID value based on a lookup/cache of the request domain. ENDEDIT But when testing locally, I'm at http://127.0.0.1:8000/, not http://my-actual-domain.com/ How do I locally view my different sites during development?

  • iPhone noob - setting NSMutableDictionary entry inside Singleton?

    - by codemonkey
    Yet another iPhone/Objective-C noob question. I'm using a singleton to store app state information. I'm including the singleton in a Utilities class that holds it (and eventually other stuff). This utilities class is in turn included and used from various view controllers, etc. The utilities class is set up like this: // Utilities.h #import <Foundation/Foundation.h> @interface Utilities : NSObject { } + (id)GetAppState; - (id)GetAppDelegate; @end // Utilities.m #import "Utilities.h" #import "CHAPPAppDelegate.h" #import "AppState.h" @implementation Utilities CHAPPAppDelegate* GetAppDelegate() { return (CHAPPAppDelegate *)[UIApplication sharedApplication].delegate; } AppState* GetAppState() { return [GetAppDelegate() appState]; } @end ... and the AppState singleton looks like this: // AppState.h #import <Foundation/Foundation.h> @interface AppState : NSObject { NSMutableDictionary *challenge; NSString *challengeID; } @property (nonatomic, retain) NSMutableDictionary *challenge; @property (nonatomic, retain) NSString *challengeID; + (id)appState; @end // AppState.m #import "AppState.h" static AppState *neoAppState = nil; @implementation AppState @synthesize challengeID; @synthesize challenge; # pragma mark Singleton methods + (id)appState { @synchronized(self) { if (neoAppState == nil) [[self alloc] init]; } return neoAppState; } + (id)allocWithZone:(NSZone *)zone { @synchronized(self) { if (neoAppState == nil) { neoAppState = [super allocWithZone:zone]; return neoAppState; } } return nil; } - (id)copyWithZone:(NSZone *)zone { return self; } - (id)retain { return self; } - (unsigned)retainCount { return UINT_MAX; //denotes an object that cannot be released } - (void)release { // never release } - (id)init { if (self = [super init]) { challengeID = [[NSString alloc] initWithString:@"0"]; challenge = [NSMutableDictionary dictionary]; } return self; } - (void)dealloc { // should never be called, but just here for clarity [super dealloc]; } @end ... then, from a view controller I'm able to set the singleton's "challengeID" property like this: [GetAppState() setValue:@"wassup" forKey:@"challengeID"]; ... but when I try to set one of the "challenge" dictionary entry values like this: [[GetAppState() challenge] setObject:@"wassup" forKey:@"wassup"]; ... it fails giving me an "unrecognized selector sent..." error. I'm probably doing something really obviously dumb? Any insights/suggestions will be appreciated.

  • How do I save an object that contains and EntitySet?

    - by Pete
    Say I have an User (mapped to a User table) and the Edit view (in MVC) displays a multiselectlist of Modules (mapped to a Modules table) that user can access, with the Modules pre-selected based on the User's EntitySet of Modules. I have tried saving the User then deleting all User_Modules manually and adding them back based on what's selected on submit, but the User has a null EntitySet for User.User_Modules. I cannot find the correct way to handle this scenario anywhere online. Can anyone help?
