  • breaking datetime into constituent parts ASP.NET MVC form

    - by nick
    hi guys, i have searched the web relentlessly for this and have not found anything - which is surprising because i would think it is such a common scenario! Basically, on my model i have a DateTime field which i wish the user to populate through a form. I am using the Html helper to render all other parts of the form (along with validation) So this question is in two parts... Html Helper Firstly, is there any way to use the Html helper to split the DateTime field to be rendered as the three constituent parts of a date: day, month, year (since i do not care about the time part). This could be rendered as text boxes, drop down lists or a combination of both. Model Binding And then when the form is posted, what is the best approach for binding back up to the model? I have seen Scott Hanselmann's solution to this, but it seems a little bloated for what i need - i was hoping for a slightly more elegant solution. Is it recommended to extend DefaultModelBinder and set that as default binder (since all dates would be handled in this way) or write a class that implements IModelBionder and set it as the default binder for the DateTime type? Thanks for all the help in advance :-) i'm loving MVC but it's infuriating me that something so trivial is causing so much headaches!

  • Power outage during disk wipe. What do I do now?

    - by Mark Trexler
    I was using Roadkil Diskwipe on an external hard drive and the power went out. I had removed it from any outlet connection by the time power was restored to prevent power-spike damage (it's on a surge protector, but I didn't want to rely on that). My question is, where do I go from here? Obviously I don't care about preserving any data currently on it, I just want to make sure the drive itself is not terminally damaged. I'm running chkdsk (full), but I don't know if that's the correct step to assessing any damage. If it makes any difference, the hard drive was unallocated at the time of the outage, as Diskwipe requires that for it to run. Also, could something like this cause latent problems with the drive itself (i.e. serious issues that I won't be aware of when testing it now). I'd appreciate any program recommendations if chkdsk is not the most appropriate diagnostic route. Thank you.

  • How to use multiple identity numbers in one table?

    - by vincer
    I have an web application that creates printable forms, these forms have a unique number on them, the problem is I have 2 forms that separate numbers need to be created for them. ie) Form1- Numbered 2000000-2999999 Form2- Numbered 3000000-3999999 dbo.test2 - is my form information table Tsel - is my autoinc table for the 3000000 series numbers Tadv - is my autoinc table for the 2000000 series numbers What I have done is create 2 tables with just autoinc row (one for 2000000 series numbers and one for 3000000 series numbers), I then created a trigger to add a record to the coresponding table, read back the autoinc number and add it to my table that stores the form information including the just created autoinc number for the right series of forms. Although it does work, I'm concerned that the numbers will get messed up under load. I'm not sure the @@IDENTITY will always return the right value when many people are using the system. (I cannot have duplicates and I need to use the numbering form show above. See code below. ** TRIGGER ** CREATE TRIGGER MAKEANID2 ON dbo.test2 AFTER INSERT AS SET NOCOUNT ON declare @someid int declare @someid2 int declare @startfrom int declare @test1 varchar(10) select @someid=@@IDENTITY select @test1 = (Select name1 from test2 where sysid = @someid ) if @test1 = 'select' begin insert into Tsel Default values select @someid2 = @@IDENTITY end if @test1 = 'adv' begin insert into Tadv Default values select @someid2 = @@IDENTITY end update test2 set name2=(@someid2) where sysid = @someid SET NOCOUNT OFF

  • CSF Unresolved issue

    - by josephmarhee
    I began receiving service failures for CSF/LFD once the limit was reached in iptables preventing the service from working properly. I flushed all iptables rules, and redid by rules using CIDR rather than the individual IPs that were listed and the issue persists. Error: The VPS iptables rule limit (numiptent) is too low (1527/1536) - stopping firewall to prevent iptables blocking all connections, at line 1459 This is after restarting CSF, which gave me: You have an unresolved error when starting csf. You need to restart csf successfully to remove this warning CSF still seems to be trying to enforce rules that no longer exists (lists entire chains upon trying to be restarted,only to fail with that error). Any idea of what's going on?

  • MySQL left outer join is slow

    - by Ryan Doherty
    Hi, hoping to get some help with this query, I've worked at it for a while now and can't get it any faster: SELECT date, count(id) as 'visits' FROM dates LEFT OUTER JOIN visits ON (dates.date = DATE(visits.start) and account_id = 40 ) WHERE date >= '2010-12-13' AND date <= '2011-1-13' GROUP BY date ORDER BY date ASC That query takes about 8 seconds to run. I've added indexes on dates.date, visits.start, visits.account_id and visits.start+visits.account_id and can't get it to run any faster. Table structure (only showing relevant columns in visit table): create table visits ( `id` int(11) NOT NULL AUTO_INCREMENT, `account_id` int(11) NOT NULL, `start` DATETIME NOT NULL, `end` DATETIME NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; CREATE TABLE `dates` ( `date` date NOT NULL, PRIMARY KEY (`date`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; dates table contains all days from 2010-1-1 to 2020-1-1 (~3k rows). visits table contains about 400k rows dating from 2010-6-1 to yesterday. I'm using the date table so the join will return 0 visits for days there were no visits. Results I want for reference: +------------+--------+ | date | visits | +------------+--------+ | 2010-12-13 | 301 | | 2010-12-14 | 356 | | 2010-12-15 | 423 | | 2010-12-16 | 332 | | 2010-12-17 | 346 | | 2010-12-18 | 226 | | 2010-12-19 | 213 | | 2010-12-20 | 311 | | 2010-12-21 | 273 | | 2010-12-22 | 286 | | 2010-12-23 | 241 | | 2010-12-24 | 149 | | 2010-12-25 | 102 | | 2010-12-26 | 174 | | 2010-12-27 | 258 | | 2010-12-28 | 348 | | 2010-12-29 | 392 | | 2010-12-30 | 395 | | 2010-12-31 | 278 | | 2011-01-01 | 241 | | 2011-01-02 | 295 | | 2011-01-03 | 369 | | 2011-01-04 | 438 | | 2011-01-05 | 393 | | 2011-01-06 | 368 | | 2011-01-07 | 435 | | 2011-01-08 | 313 | | 2011-01-09 | 250 | | 2011-01-10 | 345 | | 2011-01-11 | 387 | | 2011-01-12 | 0 | | 2011-01-13 | 0 | +------------+--------+ Thanks in advance for any help!

  • How to set/keep directory permissions?

    - by Dylan
    I'm using CwRsync to connect from my Windows development machine to a linux webserver : rsync -avuz -e ./ssh --exclude=".svn" /cygdrive/c/xampp/htdocs/project123/ [email protected]:/home/user123/public_html This syncs my development project directory nicely and fast to the server. But after doing this, all directory properties are reset to the local user user123 only, so the website is not available anymore. I need to manually reset those properties. Why is this happening, and how to prevent it? PS. coming from a Windows environment I'm having a really hard time understanding rsync. I copied the above command from some examples... just need to get this one small thing working too...

  • AD Local Admins without password sharing

    - by Cocoabean
    My team is building out an Active Directory environment in a small grad school with support for general computer labs, and staff/faculty machine and account management. We have a team of student consultants that are hired to do general help desk work. As of now we have a local admin account on every machine. It has the same password and all of us know it. I know it's not best practice and I want to avoid this with the new setup. We want to have local admin accounts in case there are network issues that prevent AD authentication, but we do not want this account to be generic with a shared password. Is there a way we can get each machine to cache the necessary information to authenticate a group of local admins so that if AD is somehow inaccessible, student consultants can still login with their AD admin accounts?

  • How to delete ProgIDs from other user accounts when uninstalling from Windows?

    - by Mordachai
    I've been investigating "how should a modern windows c++ application register its file types" with Windows (see http://stackoverflow.com/questions/2828637/c-how-do-i-correctly-register-and-unregister-file-type-associations-for-our-ap). And having combed through the various MSDN articles on the subject, the summary appears to be as follows: The installer (elevated) should register the global ProgID HKLM\Software\Classes\my-app.my-doc[.version] (e.g. HKLM\Software\Classes\TextPad.text) The installer also configures default associations for its document types (e.g. .myext) and points this to the aforementioned global ProgID in HKLM. NOTE: a user interface should be provided here to allow the user to either accept all default associations, or to customize which associations should be set. The application, running standard (unelevated), should provide a UI for allowing the current user to set their personal associations as is available in the installer, except that these associations are stored in HKCU\Software\Classes (per user, not per machine). The UN-installer is then responsible for deleting all registered ProgIDs (but should leave the actual file associations alone, as Windows is smart enough to handle associations pointing to missing ProgIDs, and this is the specified desired behavior by MSDN). So that schema sounds reasonable to me, except when I consider #4: How does an uninstaller, running elevated for a given user account, delete any per-user ProgIDs created in step #3 for other users? As I understand things, even in elevated mode, an uninstaller cannot go into another user's registry hive and delete items? Or can it? Does it have to load each given user hive first? What are the rules here? Thanks for any insight you might have to offer! EDIT: See below for the solution (My question was founded in confusion)

  • Windows 7 slowing down during hard drive activity

    - by Iniquities of evil men
    Sometimes when normally using my PC, it will (seemingly) randomly slow down, and maybe sometimes even freeze for several seconds. During this slow down period, it looks like a (I don't know which drive it is) hard drive is constantly being written to. During the last slow down, I started Windows's Ressource Monitor and found out that the System process was writing up to 10MB/s to a drive (I suspect it's the system drive, C:\, but I don't know for sure). I'm not doing anything unusual (at least, I don't think I am), and most of the time, it will work normally, but, as I said, it just randomly slows down for some times. Any ideas on what might be causing this and how I can prevent this from happening again? (I have a triple-core processor and 4GB of RAM. My system drive is a WD Caviar Black 500GB, my secondary, 'data' drive is a Samsung drive, which I don't know the model number of, but I can look it up. I can also post my full PC specs if needed.)

  • Sharepoint 2007: Edit vs Read Only Mode

    - by user29116
    Sorry about the title, dont' really know what it should be. If I open a doc in read only mode I'm able to press save and then it opens up a save as box and the default directory is the directory on the sharepoint server and if you press save you save it to the server. This actually makes the whole process not really "read only" mode since I could actually update the document. Is there a way to prevent this from happening so that if someone chooses read only there is no way possible to updload any changes back to the sharepoint site? Also, it has been suggested as a solution to get rid of the edit/read only option so that people have to check out the document. Is there a way to remove the edit/read only option on documents?

  • How to use accessors within the same class in Objective C?

    - by Azeworai
    Hi, I have a few properties defined in my header file like so @property (assign) bool connectivity_N; @property (assign) bool isConnected_N; In my implementation file I have an init and the synthesized properties like so @implementation Map @synthesize connectivity_N; @synthesize isConnected_N; a init to set the initial values like so -(id) init { if( (self=[super init]) ) { //initialise default properties self.connectivity_N=NO; self.isConnected_N=NO; } return self; } I'm running into an error that states Error: accessing unknown 'connectivity_N' class method. In this public method within the class +(bool) isConnectable:(directions) theDirection{ bool isTheDirectionConnectable= NO; switch (theDirection) { case north: isTheDirectionConnectable= self.connectivity_N; break; I'm not sure why is this so as I'm trying to grab the value of the property. According to the apple developer documentation "The default names for the getter and setter methods associated with a property are propertyName and setPropertyName: respectively—for example, given a property “foo”, the accessors would be foo and setFoo:" That has given me a clue that I've done something wrong here, I'm fairly new to objective C so would appreciate anyone who spends the time to explain this to me. Thanks!

  • RoR routing problem. Calling custom action, but getting redirected to show action

  • WCF consumed as WebService adds a boolean parameter?

    - by Martín Marconcini
    I've created the default WCF Service in VS2008. It's called "Service1" public class Service1 : IService1 { public string GetData( int value ) { return string.Format("You entered: {0}", value); } public CompositeType GetDataUsingDataContract( CompositeType composite ) { if ( composite.BoolValue ) { composite.StringValue += "Suffix"; } return composite; } } It works fine, the interface is IService1: [ServiceContract] public interface IService1 { [OperationContract] string GetData( int value ); [OperationContract] CompositeType GetDataUsingDataContract( CompositeType composite ); // TODO: Add your service operations here } This is all by default; Visual Studio 2008 created all this. I then created a simple Winforms app to "test" this. I added the Service Reference to my the above mentioned service and it all works. I can instanciate and call myservice1.GetData(100); and I get the result. But I was told that this service will have to be consumed by a Winforms .NET 2.0 app via Web Services, so I proceeded to add the reference to a new Winforms .NET 2.0 application created from scratch (only one winform called form1). This time, when adding the "web reference", it added the typical "localhost" one belonging to webservices; the wizard saw the WCF Service (running on background) and added it. When I tried to consume this, I found out that the GetData(int) method, was now GetData(int, bool). Here's the code private void button1_Click( object sender, EventArgs e ) { localhost.Service1 s1 = new WindowsFormsApplication2.localhost.Service1(); Console.WriteLine(s1.GetData(100, false)); } Notice the false in the GetData call? I don't know what that parameter is or where did that come from, it is called "bool valueSpecified". Does anybody know where this is coming from? Anything else I should do to consume a WCF Service as a WebService from .NET 2.0? (winforms).

  • Page URL and database organization.

    - by shurik2533
    I want that its name would be the page address. For example, if page has heading "Some Page", than its address should be http://somesite/some_page/. "some_page"-name generated by system automatically. "some_page" - is the unique identifier of page. The problem in that the user in the future can enter a name which already exists that will cause an error. It is necessary to find an optimum variant of the decision of a problem for great volumes of the data. I have solved a problem as follows: The page identifier in a database is the name of page and a suffix which is by default equal to zero. At page addition there is a check on existence. If such page does not exist, the suffix is equal 0 and its name is "some_page", if page is exist, than - search for the maximum number of a suffix and suffix=suffix+1 and page name become "some_page_1". For this I create in a database the compound key from fields "suffix" and "pageName": Table Pages suffix|pageName |pageTitle 0 |some_page |Some Page 1 |some_page |Some Page 0 |other_page|Other Page Addition of pages occurs through stored procedure: CREATE PROCEDURE addPage (pageNameVal VARCHAR(100), pageTitleVal VARCHAR(100)) BEGIN DECLARE v INT DEFAULT 0; SELECT MAX(suffix) FROM pages WHERE pageName=pageNameVal INTO v; IF v >= 0 THEN SET v = v + 1; ELSE SET v = 0; END IF; INSERT INTO pages (suffix, pageName) VALUES (pageNameVal, v, pageTitleVal); END; Whether there are more the best decisions?

  • Creating 1 page PDF of iPad Screen view - How?

    - by user314695
    Hi All, I've asked this question on a couple other forums and have had zero response, so I'm hoping someone here can help point me in the right direction. I have a pretty simple one screen application for my work. It's basically just a recreation of a 1 page paper report that has a company logo, some labels, a few text boxes and a scroll text box for the report. I need to be able to fill out the report then click a button to save it in a graphical form so I can fax, print or email it later. Currently, I'm just programmatically taking a screen capture and saving it to the photo's library (default for screen capture). Then I can just email it from photo's. This works ok, but is kind of hacky, at best. I've read through the new iPad 3.2 guide for creating PDF's (apparently it's supposed to be much easier than before) but I can not get it to work and I've spent countless hours on it now. I'm hoping someone has the answer for me. Alternatively, if anyone knows how I can redirect where the screen capture is stored (default is in the photo album) then maybe I can make that function work. If I could redirect the screen capture to store in my applications document folder, then I can use MFMailCompose to attach it to an email. Lastly, on a side note, does anyone know of a good way to capture a digital signature via touch. For instance, I'd love to have my users be able to just sign their name via touch at the bottom of the document before I convert to PDF or take a screen capture. Thanks in advance for your help. -Ray

  • Slow query. Wrong database structure?

  • WCF hosting: Can access svc file but cannot go to wsdl link

    - by Impulse
    Hello, I have a WCF service that is hosted in IIS 7.5. I have two servers, one for test and one for production. The service works fine on test server, but on the production server I have the following error. When I access the address http//..../service.svc I can see the default page that says: You have created a service. To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax: svcutil.exe http://..../service.svc?wsdl This will generate a configuration file and a code file that contains the client class. Add the two files to your client application and use the generated client class to call the Service. But when I click the wsdl link, I cannot go to the wsdl page. It returns me to this default web page without any errors. I am suspecting a network/firewall authorization error but does anybody have an experience like this one? All IIS settings are the same for test and production servers. Thank you, Best Regards.

  • Doing "text mode 'splash' game" during boot.

    Sometimes I want to do something (for example, playing a simple text-mode game) while the system is booting up. This is especially useful when lengthy reiserfs transaction replays are happening. Current hacky way of doing it is: Put the program on initramfs. Before running /sbin/init, "openvt 2 /my/program". Turn off messages from kernel (sysrq 0) Override /dev/console with /dev/null (to prevent boot messages). The problems are: There are STILL some messages interfering with program output. I can't see boot messages by switching to that virtual terminal back. After finishing the boot sequence, /dev/tty2 ends up being attached both to getty and my program. How to do it properly without of running graphical splashes? The system is Linux Debian Squeeze, no dependency based sysv scripts.

  • change postgres date format

    - by Jay
    Is there a way to change the default format of a date in Postgres? Normally when I query a Postgres database, dates come out as yyyy-mm-dd hh:mm:ss+tz, like 2011-02-21 11:30:00-05. But one particular program the dates come out yyyy-mm-dd hh:mm:ss.s, that is, there is no time zone and it shows tenths of a second. Apparently something is changing the default date format, but I don't know what or where. I don't think it's a server-side configuration parameter, because I can access the same database with a different program and I get the format with the timezone. I care because it appears to be ignoring my "set timezone" calls in addition to changing the format. All times come out EST. Additional info: If I write "select somedate from sometable" I get the "no timezone" format. But if I write "select to_char(somedate::timestamptz, 'yyyy-mm-dd hh24:mi:ss-tz')" then timezones work as I would expect. This really sounds to me like something is setting all timestamps to implicitly be "to_char(date::timestamp, 'yyyy-mm-dd hh24:mi:ss.m')". But I can't find anything in the documentation about how I would do this if I wanted to, nor can I find anything in the code that appears to do this. Though as I don't know what to look for, that doesn't prove much.

  • Is it safe to set MySQL isolation to "Read Uncommitted" (dirty reads) for typical Web usage? Even with replication?

    - by Continuation
    I'm working on a website with typical CRUD web usage pattern: similar to blogs or forums where users create/update contents and other users read the content. Seems like it's OK to set the database's isolation level to "Read Uncommitted" (dirty reads) in this case. My understanding of the general drawback of "Read Uncommitted" is that a reader may read uncommitted data that will later be rollbacked. In a CRUD blog/forum usage pattern, will there ever be any rollback? And even if there is, is there any major problem with reading uncommitted data? Right now I'm not using any replication, but in the future if I want to use replication (row-based, not statement-based) will a "Read Uncommitted" isolation level prevent me from doing so? What do you think? Has anyone tried using "Read Uncommitted" on their RDBMS?

  • Problems with Window Functions Wndproc and about

    - by BrianHuangverinem
    I really having problems with this problem ,it would be nice if someone help me on this. Every time I try to build my source file the same errors occur every time for the two window functions CALLBACK Wndproc and CALLBACK About. error: "local function definitions are illegal" Can you tell me what mistake I made? LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) { int wmId, wmEvent; PAINTSTRUCT ps; HDC hdc; wmId = LOWORD(wParam); wmEvent = HIWORD(wParam); switch (message) { case WM_COMMAND: // Parse the menu selections: switch (wmId) { case IDM_ABOUT: DialogBox(hInst, MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, About); break; case IDM_EXIT: DestroyWindow(hWnd); break; default: return DefWindowProc(hWnd, message, wParam, lParam); } break; case WM_PAINT: hdc = BeginPaint(hWnd, &ps); CaptureImage(hWnd); EndPaint(hWnd, &ps); break; case WM_DESTROY: PostQuitMessage(0); break; default: return DefWindowProc(hWnd, message, wParam, lParam); } return 0; } // Message handler for about box. INT_PTR CALLBACK About(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam) { UNREFERENCED_PARAMETER(lParam); switch (message) { case WM_INITDIALOG: return (INT_PTR)TRUE; case WM_COMMAND: if (LOWORD(wParam) == IDOK || LOWORD(wParam) == IDCANCEL) { EndDialog(hDlg, LOWORD(wParam)); return (INT_PTR)TRUE; } break; } return (INT_PTR)FALSE; }

  • If Statements Skipping or Evaluating Strangely, JavaScript and jquery

    - by tlm2021
    So in jQuery, I have a global variable "currentSubNav" that stores a current visible element. The following code executes on "mouseenter". I need it to get store element's ID, check to see if there was one. If there wasn't, set the new visible element to the default. $('#mainMenu a').mouseenter(function() { var newName = $(this).attr("id"); if(newName == ''){ var newName = "default"; } Then it checks to see if the new element matches the current one. If so, it returns. If not, it performs the animations to bring in the new one. if(newName == currentSubNav){ return; }else{ $("div[name=" + currentSubNav + "]").animate({"left": "+=600px", "opacity": "toggle"}, "slow"); $("div[name=" + newName + "]").css({"margin-top": "0"}); $("div[name=" + newName + "]").fadeIn(2000); $("div[name=" + currentSubNav + "]").animate({"left": "-=600px"}, 0); currentSubNav = newName; return; } }); I'm using Chrome at the moment, and according to the dev tools that isn't what happens. Problem #1 "$(this).attr("id");" isn't returning undefined as the documentation claims. It seems to be returning "". BUT, when I have the if statement as I do above, it skips over the statement entirely. I set a breakpoint, but it never pauses execuation, so the statement is never evaluated. Problem #2 After the animations occur, instead of using the return at the end of the statements it goes back and uses the return for the "newName == currentSubNav" if statement. I guess that not a big deal, but it's not the intended behavior. I'm fairly new to JavaScript, and it appears I'm missing something about how JavaScript works. But I can't find what anywhere. Any help? Blockquote

  • Preventing apps to access info from wifi device?

    - by heaosax
    Browsers like Chrome and Firefox can use my wifi device to get information about the surrounded APs and pin point my physical location using Google Location Services, I know these browser always ask for permissions to do this, and that these features can also be "turned off". But I was wondering if there's a better way to prevent ANY application to access this information from my wifi device. I don't like anyone on the internet knowing where I live, and I am worried some software could do the same as these browsers but without asking for permissions. I am using Ubuntu 10.04.
