  • get data from online once and then viewable offline

    - by user313100
    Okay, I want to have an app that takes phone numbers from an online database and displays them in a table view. When the user is not online, I want them to still be able to see the numbers they already got from the database in the table view. If the user manages to go back online, the database updates the view. My question is, is this possible to do and if so, what's the best way to approach it? (bit of a newbie, please help me out)

  • Password protect web service

    - by Henrik
    Hi! Is it possible to require user name and password for a web service without changing the code for existing web service? Adding a DLL and configuration would be OK, but I rather not change the web service.

  • 398 row datalist slowing down modal open????

    - by Jreeter
    Hey guys I got a weird issue.. I have a datalist that's only loaded on pageload it contains 2 columns a name and date and has 398 rows.. In IE 7 and above(and prob previous version) when I open a modal via a button click it takes almost 5 seconds to open. HOWEVER, if I do not bind this datalist it's MUCH faster.. Also this is only happening in IE, Chrome, Firefox and opera both open the modal instantly with the datalist binded... Josh

  • How to dynamically change fields in an .NET ORM

    - by rsteckly
    I'm working in ASP.NET in an application where often users want to add fields or change field names. I'd like to be able to have an xml schema in place that is parsed and a dynamic object model created from it that can be accessed throughout the application. My initial reaction is that this is not realistic. I think there is flexibility about the dynamic nature of it. I think the people I'm trying to build this for wouldn't mind recompiling. Even if the app recompiled, I don't know how to abstract away enough in my code access the data to allow for users changing property names, etc. How can you write LINQ when the properties might change? In short, there's two questions here: 1) is there a way to dynamically generate an object model of the database and 2) is there a way to abstract away enough so that code accessing the database doesn't break when properties change?

  • Redirect in Application_Error redundant if using customErrors?

    - by Ek0nomik
    If I have a customErrors section in my Web.config that says to redirect to Error.html, then putting code in the Application_Error method in the Global.asax to redirect to Error.html is redundant is it not? Technically, I could bypass the Web.config by redirecting to a different page in the Application_Error method if I wanted to, but since I don't want to go to a separate page I don't think I need the code.

  • I need help solving a rather weird error in a WCF service.

    - by Moulde
    Hi.. I have a solution that contains three projects. A main project with my MVC app, a silverlight application and a (silverlight enabled) WCF service project. In my silverlight project i have made a Service Reference to my WCF service. And i pretty much got that working. In my WCF service i have a method that returns an Book object, which got some random fields like title, date etc. In the book class, i have a ICollection field that contains a list of events. The book class is generated using entity framework 4.0, and Lazy Loading is enabled. If i in my getBook(int id) method return a book with the events field not initialized, it works as a charm. But if i initialize the field, i'm getting this error. The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error. I have a few ideas why that is happening, and while writing this i just got another one. The wcf service somehow threw away the reference to the event class. That would be very weird since i have a reference between my main mvc app (with the models) and my WCF service. Since i have enabled lazy loading in EF 4.0, i suspect that it may be the thing generating the error. But i'm not sure why that would be, because i'm not in any way accessing that field. I could understand that i may not be able to access the events field after i recive the object in my silverlight application since the connection between the book object and the entity framework is like broken. Did i mention that Lazy Loading is enabled on my EF instance? And there is no inner exception in the thrown exception. Thanks in advance. Malte Baden Hansen

  • "Cannot use fixed local inside lambda expression"

    - by JulianR
    I have an XNA 3.0 project that compiled just fine in VS2008, but that gives compile errors in VS2010 (with XNA 4.0 CTP). The error: Cannot use fixed local 'depthPtr' inside an anonymous method, lambda expression, or query expression depthPtr is a fixed float* into an array, that is used inside a Parallel.For lambda expression from System.Threading. As I said, this compiled and ran just fine on VS2008, but it does not on VS2010, even when targeting .NET 3.5. Has this changed in .NET 4.0, and even so, shouldn't it still compile when I choose .NET 3.5 as the target framework? Searching for the term "Cannot use fixed local" yields exactly one (useless) result, both in Google and Bing. If this has changed, what is the reason for this? I can imagine capturing a fixed pointer-type in a closure could get a bit weird, is that why? So I'm guessing this is bad practice? And before anyone asks: no, the use of pointers is not absolutely critical here. I would still like to know though :)

  • How to convert "0" and "1" to false and true

    - by Chris
    I have a method which is connecting to a database via Odbc. The stored procedure which I'm calling has a return value which from the database side is a 'Char'. Right now I'm grabbing that return value as a string and using it in a simple if statement. I really don't like the idea of comparing a string like this when only two values can come back from the database, 0 and 1. OdbcCommand fetchCommand = new OdbcCommand(storedProc, conn); fetchCommand.CommandType = CommandType.StoredProcedure; fetchCommand.Parameters.AddWithValue("@column ", myCustomParameter); fetchCommand.Parameters.Add("@myReturnValue", OdbcType.Char, 1). Direction = ParameterDirection.Output; fetchCommand.ExecuteNonQuery(); string returnValue = fetchCommand.Parameters["@myReturnValue"].Value.ToString(); if (returnValue == "1") { return true; } What would be the proper way to handle this situation. I've tried 'Convert.ToBoolean()' which seemed like the obvious answer but I ran into the 'String was not recognized as a valid Boolean. ' exception being thrown. Am I missing something here, or is there another way to make '1' and '0' act like true and false? Thanks!

  • What is the pros and cons in using FormsAuthentication to persist login cookie?

    - by stacker
    What is the pros and cons in using FormsAuthentication to persist a login cookie? I see that StackOverflow ignore FormsAuthentication and instead implemented a different strategy to persist a login cookie. Pros Out of the box implementation for persistent login feature. Cons The login feature depends on the machine key which mean that I need to make sure that the machine key is the same on all the servers in the farm. The cookie contains wired encrypted values that don't really make sense to store in the cookie.

  • Approach to data wrapping

    - by Mikhail
    I'm developing in PHP and MySQL. The information about the currently logged in user is stored in many different tables. The information that I need on each page, I preload. However if something is needed from a rarely accessed table - then I do $newdata = $db->Query('SELECT * FROM rare_table WHERE user_id='.$user->id); I would like to simplify the above to a point where I don't have to specify that the query should be limited to this particular user. An ideal function call would be: $newdata = $user->Query('SELECT * FROM rare_table'); Obviously I'd have to parse the SQL and add a WHERE clause. Or add to the already existing clause. Questions: are there tools to do this? How can I develop this? Is this even a good idea?

  • How can I get the assembly last modified date?

    - by Juan Manuel Formoso
    I want to render (for internal debugging/info) the last modified date of an assembly, so I know when was a certain website deployed. Is it possible to get it though reflection? I get the version like this, I'm looking for something similar: Assembly.GetExecutingAssembly().GetName().Version.ToString(); ie: I don't want to open the physical file, get its properties, or something like that, as I'll be rendering it in the master page, and don't want that kind of overhead.

  • Adding Controls Programatically

    - by Mike Keller
    I have a page I need to build out where depending on the selection the user made on a form on the page prior it displays a different set of questions for them to answer. So say the user selects Reason A from the form on page edit, then it needs to display Questions 1 and 2 on page edit_confirmation. But if they select Reason B then it needs to display Questions 3 and 4. I'm grabbing the reason code from the query string and have a switch statement set up, but I can't find anywhere how to output different controls. If Questions 1 and 2 are supposed to show up, one could be a text box and the other a checkbox, but if questions 3 and 4 are supposed to show up one may need to be a dropdown list and a checkbox.

  • C++ union data-structure, easy acccess of bits within a DWORD

    - by TK
    Im running through a set of DirectX tutorials online and I have the following structure: struct CUSTOMVERTEX { FLOAT x, y, z, rhw; // from the D3DFVF_XYZRHW flag DWORD color; // from the D3DFVF_DIFFUSE flag } My basic understanding of directX leads me to thing tha color is made up of 8-bit alpha, red, green and blue channels. I am attempting to get east access to these channels. Rather than write the following code numerous times (within the CUSTOMVERTEX structure): public: int red() { return (color & 0x00FF0000) >> 16; } I could write a more elegant somution with a combination of a union and a structure e.g. struct CUSTOMVERTEX { FLOAT x, y, z, rhw; // from the D3DFVF_XYZRHW flag #pragma pack(2) union { DWORD color; // from the D3DFVF_DIFFUSE flag struct { char a; char r; char g; char b; }; }; } However this does not appear to function as expected, the values in r, g, & b almost appear the reverse of whats in color e.g. if color is 0x12345678 a = 0x78, r = 0x56. Is this an endieness issue? Also what other problems could I be expecting from this solution? e.g. overflow from the color members? I guess what Im asking is ... is there a better way to do this?!

  • Is it possible get the functionality of namespaces inside a class?

    - by CowKingDeluxe
    I have the following code: Public Class Form1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Class What I would like to do is be able to separate the code, similar to the following (which obviously doesn't work): Public Class Form1 Namespace Step1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function End Namespace Namespace Step2 Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Namespace End Class I would like the functionality of namespaces inside of a class, as in something that would let me call Step2.Execute() instead of having to put Step2_ in front of a whole bunch of functions. I don't want to have to create separate classes / modules for step1, step2, etc. Is there a way that I can accomplish namespace functionality from inside a class?
