ADO.NET :: String Array In Model Object - Store In Database?
Feb 6, 2011
I been working on a simple site today and when I found myself surprised about this. I got a object model that gone have like a lot of emails to it so I thought Ill do a string array to keep them, then I paused and tried to figure how do I save that to a database and how do I work with this? I always found myself working with collections of objects instead. So I'm kinda embaries to say this but how do I work with this? can I save a array to database
I would like to store an array of string or a List<string> in a Hiddenfield. You can c the code I am trying below :
public int[] ListEmails{ get { if (hdnEmailBody.Value.Length == 0)return new List<string>();return hdnEmailBody.Value.Split(); }set { hdnEmailBody.Value = ? } } value;
I want to pass the Array ( object[]) or Structure data type value to the store procedure through ibatis .net. I can do same by commandtext using SQLDBType.Structure. I am using Table value function in sql server 2008 and .Net 2010.
I am develping an application that integrates with an RFID kit. The problem is, the kit comes with an .cs class that accepts data stored in a byte array however, each information stored in the array respresents an int. I wanted to store String information in each array but, my research suggest that a String itself can be converted to a byte array and not a byte....here the code from the .cs class:
I am trying to get the FailedPasswordAttemptCount from the ASP.NET built in objects and I am not able to find one, is there any way I can get this value without creating a new storedProc?
I ask this because i'm using Partial classing to extend my db model, and in doing so some snags i've run into using inheritance and also snags i've run into declaring my db model in another class as a property and just using it like that ie: Public Property DBModelClass as DBModelClassType - however, doign direct partial classing has worked out the best, with no snags... except for an issue i seem to be running into now.
that is, i create new properties with half-page code in the 'Get' part of the property decleration, these are like virtual/new properties that the db or db model isn't supposed to know anything about, the sort of stuff you generate/use but without saving it in your db, as i'm sure all of you have these. every time i submit my DBModel through an action, somehow, one of these properties 'Get' section is running (being called) even though i'venever asked for it to. of course, because it aint ready to run (it shouldn't) errors like null errors get returned (however, they wouldn't error if it were to run only when i asked for it to).
edit:
so this second part of my question, are all properties in a model generated from a db (linq to sql) ran or called by the model state automatically? without being asked to do so?
an aside:
(i do do a modelstate.isvalid - however, this running occurs before isvalid is called as it errors out before i even see validation information). that being, is the auto calling of all properties on a db model object even when not used normal? i tried using bind(false) and scaffold off on the problemed properties. and the first part of my question, just as a reminder, is if i should or should not be using partial classing as a substitute to inheritance when extending db model's?
I'm building an MVC 2 RTM app, and I want to be able to share my model across applications. I'd *like* to be able to implement it like:ASP.NET MVC2 app (holds Views and Controllers)Class library to hold Model(s)WCF app to handle the data transactions with the models via different data stores across apps I had the MVC app working fine, but I wanted to abstract the data stuff and be able to work with the model across apps through the WCF site, so I created a class library project and moved all of the Models classes into that and set-up a WCF app, then added project references to the MVC and WCF apps that point at the class library. The idea was I can create services that take and return objects from the model via method calls across apps. It appears that everything's wired up correctly in the MVC project, so I'm passing the objects stored in the Models class library between controllers and views and everythig is compiling just fine, but for some reason the data is not being passed back from the views to the controller on POST -- all of the properties in the classes are null or empty.
When I debug the app, I can see that the values are stored in the model data dictionary but not the model object itself. What am I doing wrong? Am I on the wrong path, or missing something obvious (to some)?
Iam getting an array of list from database to client side(javascript array). Now my aim to place those values in a div one by one and that div should attach to the textbox similar to Autocomplete extender.
I have developed a website that allows users to upload office documents then uses the office object model to convert the document to an HTML file that it then displays in an iFrame. I have, of course, included references to Office.interop.word, and the site works fine on my development machine. When I uploaded it to my production server the site functions fine until I try to upload a document. I initially got a similar error that said "COM object not registered". I realized that Word wasn't installed on my production server. So I installed word and now when the server tries to access the word object model I receive the following error:
Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
I searched the registry for the corresponding CLSID and found a corresponding folder. I added full control to the IUSR_ account and due to the persistence of the error I eventually added full control to "everyone" and ensured these permissions inherited down to the rest of the folder. I then added full control to IUSR_ and again eventually added full control to "everyone" to my microsoft office folder. I don't know what other permissions to grant and where in order to make this "Access is denied" error go away. I must be granting them in the wrong place, because as far as I know I can't be any more permissive than "Everyone" "Full Control".

I am looking here to find a quick and easy way to bind a list of checkbox list items when the postback occurs in the model. Apparently the common way to do it now seems to do it like this form.GetValues("checkboxList")[0].Contains("true"); It seems painfull and not exactly safe. Is there a way to bind a list of checkbox (that are created with or without an helper in the view) or even an array of data for that matters during the UpdateModel(myViewModel, form.ToValueProvider()); phase which would populate an IList<string> or string[] inside of the model ?
