  • Slow SQL Sync with Microsoft Sync Framework on Mobile Client

    - by Malkier
    Hello, we are developing an application which uses MS Sync Framework to sync data between Windows CE 6.0 with SQL CE 3.5 SP1 Clients and an SQL 2008 Database. Our major problem is a slow sync time up to 1 minute for 15 tables which are totally empty. Here's a break down of our components: Server: Sql Server 2008 15 tables with activated change tracking WCF Service with endpoint for the mobile sync (uses Sync Framework 2.0) Client (Mobile) Windows CE 6.0 NET Application using Sync Framework for Devices (CTP 1) which starts the sync As I mentioned above, the sync takes up to 1 minute without any changes and empty tables. The mobile device is in its dock. This is a deal breaker for a production environment. Does anybody have any experience in this field? Is there a way to improve things? Thanks for any responses.

  • Android installation in a mobile

    - by Sundar
    Is it possible to install Android in a normal mobile phone? I have Sony Ericsson Naite which has only key pad interface (No touch). I would like to install Android in my phone for experimenting with it. It will be great if its possible to dual boot Android with Symbian :-). Do we need any other special hardware to install operating system in a mobile phone? Will Android work on a key-pad mobile? Any pointer/suggestion is appreciated. Thank you in advance.

  • Facebook Connect - Mobile

    - by Jayrox
    I am currently in the process of creating a mobile version of my web app. The app is being developed with Facebook's PHP Client Library. The issue: I am using the following mobile url to allow users to log in using the mobile devices: http://m.facebook.com/tos.php?api_key=APIKEY&v=1.0&next=http%3A%2F%2Ftweelay.net%2Fm.php&cancel=http%3A%2F%2Ftweelay.net%2Fm.php APIKEY being my app's actual Facebook API key. In the url I am telling Facebook to redirect the user back to http://tweelay.net/m.php when the user signs in or clicks cancel on the log in screen. I am pulling my hair trying to figure out why it keeps sending the user to http://m.tweelay.net/m.php which is currently an invalid end point. I have gone through all of my app's settings on Facebook and I cant find any that reference http://m.tweelay.net and going through all of my source code I cant find any that reference the m. sub-domain either.

  • C# differences between Windows Mobile and regular Windows

    - by Matt
    Are there many differences between Windows and Windows Mobile as far as C# programming is concerned? I can write some moderately complicated programs in C#, but I'm not sure if it would just run perfectly on a Windows smartphone, or if something has to be done to port it. If so, is there a tool that will automatically revise code to make it mobile-compatible? The reason I ask is that the new Windows mobile 7 will only support a few methods of app development, one of which is C#. Also, do smartphones with non-windows operating systems have C# support available? Or can C# code be converted to Symbian or iPhone or whatever? Thanks for any help you can provide.

  • Persisting cookie for iPhone UIwebview mobile web app

    - by Brad Thomas
    I'm using MVC4 forms auth. My mobile web app runs in full screen UIwebview on iphone. I have a home screen icon for my mobile web app. The app needs to launch external links. Those launch in Safari, which works fine. However returning to the mobile web app by clicking again on the home screen icon, seems to have logged the user out. Ideally I want the user to remain logged into the web app after viewing the external links in Safari. Maybe the cookie got deleted? Can I persist the cookie?

  • CSS for mobile sometimes reverts back to original

    - by Jessie
    So most of the time my stylesheets appear properly. The standard/original one always works flawlessly, however it seems sometimes the mobile one is disregarded when looked at from a mobile device I have them designated as follows: <link runat="server" href="CustomStyleSheets/Menu.css" rel="stylesheet" type="text/css" /> <link href="CustomStyleSheets/mobile.css" rel="stylesheet" type="text/css" media="only screen and (max-device-width: 799px)" /> I'm using a Droid X to view the page, in portrait mode, so the device width shouldn't be exceeding the max-width specified above, but sometimes, randomly, it still reverts back to the original css page. Any way to keep it from doing so?

  • Examples of mobile frameworks that support AdSense for mobile content ads?

    - by David Sky
    I’ve tried, I really have, to find examples of serving up AdSense for mobile content ads in any of the popular mobile frameworks, but can’t find running webpages with ads, nor tutorials, etc.... I’ve done some iUI work, but would consider jQueryMobile, iWebKit, even sencha-touch if I could find an example that actually displays ads within the framework on an iPhone, iPod touch,etc... I realize there are issues with the HTML adSense generates, but hasn’t anyone found a work-around? Surely some mobile HTML sites must be serving up ads? Links to tutorials would be much appreciated!

  • Developing web app, question for mobile developers

    - by Stephen Kellett
    I'm going to develop a web app that I expect some people will also end up wanting to view on their phones. The UI will be fairly straightforward (no frames, just CSS/HTML). May have a bit of Flash, but not for the first version. My question is, for testing viewing of the web app on mobile devices what devices would you recommend that I test on (and thus, most likely, have to purchase)? Windows Mobile iPhone Android Other? or can I use emulators for any/all of these? Note that I'm not developing a platform (android, iPhone) specific app, just a web application that I expect will also be accessed from a mobile phone. I apologise if this seems like a niave/stupid question, but this hobby project is totally away from my commercial experience and I just don't know the answers to these questions, hence asking here. Thanks for reading.

  • Mobile web development - how to?

    - by Adam Kiss
    Hello, I would like to start developing mobile-friendly versions of websites for my clients, however, I am baffled with options and google search wasn't very helpful - there is so many options and opinions, I've been reading for few days now and still have no idea how to start. What's your opinion/experience about/with it? My main points: mobile devices supported (in order of relevance): iPhone 3G, iPhone 2G, Blackberry, Droid powered mobiles, other phone friendly numbers, phone friendly emails contact/register form working on each (or the most possible) devices listed jQTouch seems superb (simple, quick, working), I'm not sure about it on blackberry/droid and I don't want to create 6 web versions for each mobile device - Makes even less sense if you consider, that I'm starting with small web (6-10 pages, 1 contact form, 3 register forms) to play with. Thank you

  • Crowdsourcing translation for mobile developers?

    - by superg
    I am developing applications for mobile phones with different operating systems (Android, Symbian, iPhone). Applications are sold internationally so they need to be translated to different languages in addition to english version. I assume most mobile developers do the translations using some paid external service each time. This approach does not look very cost-effective to me. Would it make sense to have a website where simple translations would be done using crowdsourcing (other developers)? Most strings in mobile applications are very simple and short, for example "OK, "Cancel", "Are you sure?", "Please enter your password". Also the same strings are used in hundreds of applications. Instead of paying for translating all strings, developers could save money by only buying their difficult application specific translations. Does anyone agree with this idea? I have seen many opensource projects doing the translations succesfully using volunteers.

  • Background task in mobile phone to access a secure element and a web server

    - by Splryxx
    Is it possible in a GSM mobile phone OS (e.g. Android, Win Mo, Symbian, etc.) to have some kind of background task or application able to exchange data at the same time with a web server and a secure element of the mobile? The purpose if for the web server to be able to push APDUs to the secure element (an retrieve response APDUs) without activating the IHM of the mobile. NB: I know that this is possible when the secure element is the one managing the GSM baseband, for example using BIP as described in Ulysse specifications. My question is only when using another secure element (e.g. Java Card in a microSD).

  • Uniquely identifying mobile devices over a network for webforms

    - by Eric
    I'm designing a system for mobile devices that can be assigned only to one job at a time. So I need to be able to know which mobile device is being used by accessing it's own unique static IP address or its device ID. I don't want to assign an ID myself for every machine that comes in which is why a static IP would work great. However, in trying to retrieve the client ip address I'm retrieving the wireless router's ip or some other ip which is not the mobile device's ip. I want to store that ip in a table and control which jobs are assigned to it. How can I accomplish this? I've tried the following but I'm getting the wireless ip: var hostEntry = Dns.GetHostEntry(Dns.GetHostName()); var ip = ( from addr in hostEntry.AddressList where addr.AddressFamily.ToString() == "InterNetwork" select addr.ToString() ).FirstOrDefault(); I'd rather not set a cookie if there exists a better alternative. TIA!

  • Excel 2010: dynamic update of drop down list based upon datasource validation worksheet changes

    - by hornetbzz
    I have one worksheet for setting up the data sources of multiple data validation lists. in other words, I'm using this worksheet to provide drop down lists to multiple other worksheets. I need to dynamically update all worksheets upon any of a single or several changes on the data source worksheet. I may understand this should come with event macro over the entire workbook. My question is how to achieve this keeping the "OFFSET" formula across the whole workbook ? Thx To support my question, I put the piece of code that I'm trying to get it working : Provided the following informations : I'm using such a formula for a pseudo dynamic update of the drop down lists, for example : =OFFSET(MyDataSourceSheet!$O$2;0;0;COUNTA(MyDataSourceSheet!O:O)-1) I looked into the pearson book event chapter but I'm too noob for this. I understand this macro and implemented it successfully as a test with the drop down list on the same worksheet as the data source. My point is that I don't know how to deploy this over a complete workbook. Macro related to the datasource worksheet : Option Explicit Private Sub Worksheet_Change(ByVal Target As Range) ' Macro to update all worksheets with drop down list referenced upon ' this data source worksheet, base on ref names Dim cell As Range Dim isect As Range Dim vOldValue As Variant, vNewValue As Variant Dim dvLists(1 To 6) As String 'data validation area Dim OneValidationListName As Variant dvLists(1) = "mylist1" dvLists(2) = "mylist2" dvLists(3) = "mylist3" dvLists(4) = "mylist4" dvLists(5) = "mylist5" dvLists(6) = "mylist6" On Error GoTo errorHandler For Each OneValidationListName In dvLists 'Set isect = Application.Intersect(Target, ThisWorkbook.Names("STEP").RefersToRange) Set isect = Application.Intersect(Target, ThisWorkbook.Names(OneValidationListName).RefersToRange) ' If a change occured in the source data sheet If Not isect Is Nothing Then ' Prevent infinite loops Application.EnableEvents = False ' Get previous value of this cell With Target vNewValue = .Value Application.Undo vOldValue = .Value .Value = vNewValue End With ' LOCAL dropdown lists : For every cell with validation For Each cell In Me.UsedRange.SpecialCells(xlCellTypeAllValidation) With cell ' If it has list validation AND the validation formula matches AND the value is the old value If .Validation.Type = 3 And .Validation.Formula1 = "=" & OneValidationListName And .Value = vOldValue Then ' Debug ' MsgBox "Address: " & Target.Address ' Change the cell value cell.Value = vNewValue End If End With Next cell ' Call to other worksheets update macros Call Sheets(5).UpdateDropDownList(vOldValue, vNewValue) ' GoTo NowGetOut Application.EnableEvents = True End If Next OneValidationListName NowGetOut: Application.EnableEvents = True Exit Sub errorHandler: MsgBox "Err " & Err.Number & " : " & Err.Description Resume NowGetOut End Sub Macro UpdateDropDownList related to the destination worksheet : Sub UpdateDropDownList(Optional vOldValue As Variant, Optional vNewValue As Variant) ' Debug MsgBox "Received info for update : " & vNewValue ' For every cell with validation For Each cell In Me.UsedRange.SpecialCells(xlCellTypeAllValidation) With cell ' If it has list validation AND the validation formula matches AND the value is the old value ' If .Validation.Type = 3 And .Value = vOldValue Then If .Validation.Type = 3 And .Value = vOldValue Then ' Change the cell value cell.Value = vNewValue End If End With Next cell End Sub

  • Validate form fields from InfoPath custom code

    - by Alex Angas
    I'm developing an InfoPath form for Forms Services. It has these views: View 1 asks the user to input some basic initial data View 2 calls a web service based on data in View 1 and populates drop-downs accordingly At the bottom of View 1 I've added a Next > button to move to View 2. As part of clicking that button I would like the inputs in View 1 to be validated first. However, there don't appear to be any rules that validate a view or anything in the object model to execute validation rules. Is there code that can trigger a field's validation event?

  • Trouble with client side validation using Struts 2. Xml based validation rules not recognized.

    - by Kartik
    Hi, This is my first post to ask a question on stack overflow and my issue is that when I don't see a client side validation error message when I don't enter any values for that field even when it is configured as required. The input page is reloaded but no error message is seen. I am not sure what I am doing wrong. Any advice would be greatly appreciated.

    - by Abu Hamzah
    i have a strange situation may its a easy fix or something i may be missing but here is the question. i have a asp.net form with master page and my validation works great without any problem but the problems starts when i try to hook my click event to the server side, here is what i meant: i have a form with few fields on it and if the form is empty than it should STOP submitting, otherwise allow me to execute the server side script but its not happening, even my form is in invalid state (i do get error message saying i have to enter the required fileds) but still executing my server side script. i would like to execute my server side script only if the form is in valid state. here is my code: my master page <%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>jQuery Validation in ASP.NET Master Page</title> <script src="Scripts/jquery-1.3.2.js" type="text/javascript"></script> <script src="Scripts/jquery-1.3.2-vsdoc2.js" type="text/javascript"></script> <script src="Scripts/jquery.validate.js" type="text/javascript"></script> <asp:ContentPlaceHolder id="head" runat="server"> </asp:ContentPlaceHolder> </head> <body> <form id="form1" runat="server"> <div> <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> </div> </form> </body> </html> my content page: <%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"> <script type="text/javascript"> $(document).ready(function() { $("#aspnetForm").validate({ rules: { <%=txtName.UniqueID %>: { minlength: 2, required: true }, <%=txtEmail.UniqueID %>: { required: true, email:true } }, messages: { <%=txtName.UniqueID %>:{ required: "* Required Field *", minlength: "* Please enter atleast 2 characters *" } } }); }); </script> Name: <asp:TextBox ID="txtName" MaxLength="30" runat="server" /><br /> Email: <asp:TextBox ID="txtEmail" runat="server"></asp:TextBox><br /> <asp:Button ID="btnSubmit" runat="server" onclick="SubmitTheForm();" Text="Submit" /> </asp:Content> function SubmitTheForm() { SaveTheForm(); } function SaveTheForm() { debugger; var request = buildNewContactRequest(); ContactServiceProxy.invoke({ serviceMethod: "PostNewContact", data: { request: request }, callback: function(response) { processCompletedContactStore(response); }, error: function(xhr, errorMsg, thrown) { postErrorAndUnBlockUI(xhr, errorMsg, thrown); } }); return false; }

  • ASP.NET MVC DropDownList Validation

    - by Andrew Florko
    Hello everybody, I have [DisplayName("Country")] public List<SelectListItem> Countries { get; set; } property in Model class for DropDownList. When I try to check if the ModelState.IsValid on form postback it's always false & error for Countries tells "Can't convert [value] to SelectListItem" or some of a kind. I figured out there is no straight-forward mapping for drop down selected value (looks like I'll have to read value from Form value collection), but how can I ignore binding and validation for List property? I just want to make ModelState.IsValid attribute to be true if all the other fields are populated properly. Thank you in advance

  • X.509 Certificate validation with Java and Bouncycastle

    - by Rob
    Hi, through the bouncycastle wiki page I was able to understand how to create a X.509 root certificate and a certification request, but I do not quite understand how to proceed concept- and programming wise after that. Lets assume party A does a cert request and gets his client certificate from the CA. How can some party B validate A's certificate? What kind of certificate does A need? A root certificate? A 'normal' client certificate? And how does the validation work on programming level, if we assume that A has successfully send his certificate in DER or PEM format to B? Any help is much appreciated. Best Regards, Rob

  • problem with jsf / icefaces depended form fields and validation

    - by hubertg
    Hi, I have a form with 3 fields (simplyfied example). The first one is a checkbox. <ice:selectBooleanCheckBox value=#{backingBean.bean.visible} ID=checkbox1 partialSubmit=true> The second one is a <ice:inputText ID=text1> The third one is also a <ice:inputText ID=text2> text1 should only be visible when checkbox1 is checked. text2 is a required field. So my first approach with just using #{backingBean.bean.visible} failed because text2 has is required and a validation message appeared (after the checkbox was clicked) when the text2 field is empty. Because of ths valdation error the form was never completely submitted such that the visible property is set (update model phase was never reached). So my question: how can I make sure text1 is only visible when checkbox1 is clicked? Thanks.

  • jQuery, insertBefore, validation, Placement of error message

    - by Steve
    I am using insertBefore under errorplacement to add validation messages, each one below each other as I want the order of the messages to go from top to bottom. I am using a hidden input at the very bottom of a parent element in order to supply an element for the insertBefore argument. Is there a way to insert from the bottom without using the dummy hidden element? If I use absolute positioning, there is a possibility for white space, for example 3 stacked messages, the middle one missing since there is no collapsing with absolute positioning.

  • Django Formset validation with an optional ForeignKey field

    - by Camilo Díaz
    Having a ModelFormSet built with modelformset_factory and using a model with an optional ForeignKey, how can I make empty (null) associations to validate on that form? Here is a sample code: ### model class Prueba(models.Model): cliente = models.ForeignKey(Cliente, null = True) valor = models.CharField(max_length = 20) ### view def test(request): PruebaFormSet = modelformset_factory(model = Prueba, extra = 1) if request.method == 'GET': formset = PruebaFormSet() return render_to_response('tpls/test.html', {'formset' : formset}, context_instance = RequestContext(request)) else: formset = PruebaFormSet(request.POST) # dumb tests, just to know if validating if formset.is_valid(): return HttpResponse('0') else: return HttpResponse('1') In my template, i'm just calling the {{ form.cliente }} method which renders the combo field, however, I want to be able to choose an empty (labeled "------") value, as the FK is optional... but when the form gets submitted it doesn't validate. Is this normal behaviour? How can i make this field to skip required validation?
