Where To Put Custom Object Formatter In MVC Application

Jan 12, 2011

I'm teaching myself ASP.NET MVC, and am trying to figure out where best to put a function which takes in an Models.Address instance and returns an IHtmlString instance which reads something like:

Line 1<br />
Line 2<br />
City, State

The string could be used in many places throughout my project, so I don't want to write it in one view and have to keep copy-pasting it or attaching that view: By the same logic attaching it to ViewData seems like a bad idea. However, the HtmlEncode method requires an instance of server, which means I can't add the function to the model class either.

Is there a right place to put this - some sort of shared view? (does this belong in the master?) Or am I going about this all wrong?

My current best idea is to create a ViewModel with the method public IHtmlString FormatAddress(Address address, HttpServerUtility server), but I don't know if that's the ASP.NET MVC way to do it.

C# - Cannot Find Suitable Formatter For Custom Class Object

Apr 13, 2010

I'm writing messages to a Message Queue in C# as follows:

ObjectMsg objMsg = new ObjMsg(1,"ascii",20090807);
Message m = new Message();
m.Formatter = new BinaryMessageFormatter();
m.body = objMsg;
queue.Send(m);

and I'm trying to read the messages as follows:

Message m = new Message()
m.Formatter = new BinaryMessageFormatter();
MessageQueue mq = new MessageQueue("./pqueue");
m = mq.Recieve();
ObjMsg msg = (ObjMsg )m.Body;

However I'm getting an error message which says: "Cannot find a formatter capable of reading this message."

How To Bind Form Collection Back To Custom Model Object That Uses 2 Custom Objects

Mar 23, 2010

What I'm trying to do is rather basic, but I might have my facts mixed up. I have a details page that has a custom class as it's Model. The custom class uses 2 custom objects with yet another custom object a property of one of the 2. The details page outputs a fair amount of information, but allows the user to post a comment. When the user clicks the post button, the page gets posted to a Details action that looks something like this:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Details(VideoDetailModel vidAndComment) { ....}
[Code]....

The only fields on the form that is posted are CommentText and VideoId. Here is what the VideoDetailModel looks like.

public class VideoDetailModel
{
public VideoDetailModel()
{
[Code]....
I suppose if I added more form fields for the properties I need, they would get posted, but I only need 1 form entry field for the CommentText. If I could get the same Model objects value that were sent to the page to post with the page, it looks like the solution is rather simple. I think using the RenderPartial in the middle of a form is problematic somehow to how the form gets written in html. I can't really put my finger on why things went bonkers, but if I do my RenderPartials before my form and then begin my form with the text entry field and the hidden VideoId, the default ModelBinder works just fine. I was beginning the form, writing the hidden VideoId, rendering several partial views, create my CommentText field, and then closed the form out. The CommentText field would get bound just fine. The hidden VideoId would not. Maybe I missed a rule somewhere about using RenderPartial.

For completeness, the partial view I was rendering took a Comment object and just wrote out it's CommentText data. Several of these objects would exist for a single Video object. All of this data was in a custom type and passed into the View (the main view) as it's Model. This partial view did not have a form and did not have any data entry fields.

C# - Dispose Of Custom Object From Within Custom Membership Provider?

Apr 16, 2010

I have created my custom MembershipProvider. I have used an instance of the class DBConnect within this provider to handle database functions. Please look at the code below:

public class SGIMembershipProvider : MembershipProvider
{
#region "[ Property Variables ]"
private int newPasswordLength = 8;
private string connectionString;
private string applicationName;
private bool enablePasswordReset;
private bool enablePasswordRetrieval;
private bool requiresQuestionAndAnswer;
private bool requiresUniqueEmail;
private int maxInvalidPasswordAttempts;
private int passwordAttemptWindow;
private MembershipPasswordFormat passwordFormat;
private int minRequiredNonAlphanumericCharacters;
private int minRequiredPasswordLength;
private string passwordStrengthRegularExpression;
private MachineKeySection machineKey;
**private DBConnect dbConn;**
#endregion
.......
public override bool ChangePassword(string username, string oldPassword, string newPassword)
{
if (!ValidateUser(username, oldPassword))
return false;
ValidatePasswordEventArgs args = new ValidatePasswordEventArgs(username, newPassword, true);
OnValidatingPassword(args);
if (args.Cancel)
{
if (args.FailureInformation != null)
{
throw args.FailureInformation;
}
else
{
throw new Exception("Change password canceled due to new password validation failure.");
}
}
SqlParameter[] p = new SqlParameter[3];
p[0] = new SqlParameter("@applicationName", applicationName);
p[1] = new SqlParameter("@username", username);
p[2] = new SqlParameter("@password", EncodePassword(newPassword));
bool retval = **dbConn.ExecuteSP("User_ChangePassword", p);**
return retval;
} //ChangePassword
public override void Initialize(string name, NameValueCollection config)
{
if (config == null)
{
throw new ArgumentNullException("config");
}
......
ConnectionStringSettings ConnectionStringSettings = ConfigurationManager.ConnectionStrings[config["connectionStringName"]];
if ((ConnectionStringSettings == null) || (ConnectionStringSettings.ConnectionString.Trim() == String.Empty))
{
throw new ProviderException("Connection string cannot be blank.");
}
connectionString = ConnectionStringSettings.ConnectionString;
**dbConn = new DBConnect(connectionString);
dbConn.ConnectToDB();**
......
} //Initialize
......
} // SGIMembershipProvider

I have instantiated dbConn object within Initialize() event. My problem is that how could i dispose off this object when object of SGIMembershipProvider is disposed off. I know the GC will do this all for me, but I need to explicitly dispose off that object. Even I tried to override Finalize() but there is no such overridable method. I have also tried to create destructor for SGIMembershipProvider.

Enterprise Library 3.1 Logging Formatter Template - Include URL Request

Feb 9, 2011

We have a custom web app built using Ektron v8.0 which uses EL 3.1 and the format template in the logging config is configured as such:

<add
name="Text Formatter"
type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, Microsoft.Practices.EnterpriseLibrary.Logging"
template="Timestamp: {timestamp}
Message: {message}
Category: {category}
Priority: {priority}
EventId: {eventid}
Severity: {severity}
Title:{title}
Extended Properties: {dictionary({key} - {value}
)}"
/>

Is there a template item for Request URL? Without the request url with querystring parameters, it's difficult to debug errors.

How To Bind A GridView To A Custom Object

Apr 1, 2011

If I have the following ASP.NET code (it's not complete - obviously there's a lot missing, but none of it matters):

<asp:GridView>
<Columns>
<asp:TemplateField>
<ItemTemplate>
My Label: <asp:Label />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
My Text Box: <asp:TextBox />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

And if I have something like this in the CodeBehind:

Private MyListOfObjects As List(Of MyObject)
...
Public Class MyObject
Public MyTextBoxString as String
Public MyLabelString as String
End Class

How can I bind the GridView so that one row is equivalent to one item in my MyListOfObjects list, and so that the data will populate and persist across page loads or postbacks? I've never done custom databinding like this before. All the tutorials I've come across so far only talk about using GridViews directly with Database query results, and that's not what I need.

How To Add Some Custom Instance Properties To User Object

Nov 29, 2010

I'd like to add some custom instance properties to an ASP.Net User object. for example, I'd like to log every user's login and have something like: User.LoginTimes or calculate the User Profile's Completion percentage and be able to access it like: User.ProfileInfoPercentage, etc.

Now What I'd like to know is what would be the best approach to do this?

Forget about user instances? (e.g. define a database table with userid and ProfilePercentage info and retrieve data from profile like: DB.GetProfilePercentage(Context.Current.User.UserID) )
Override the ASP.Net User class and add my own functionalities.
Use Extension methods for the user class.

How To Expose Custom Object (with Sub Objects) In Web Service

Feb 11, 2010

I'm kinda new to web services and want to make sure I am doing things correctly.

I have a custom object which has sub objects as well. (let's say Company object, sub object is collection of Employee objects)

I want the web service to return a collection of Company objects. Do I make the service return a Dataset and custom generate a dataset with datatables representing the different objects?

What is the best way to do this? I tried to just serialize it, but that doesn't seem to work either.

I tried this dll

[URL]

But the output XML doesn't seem to include the sub object.

WCF / ASMX :: Custom Object Types And Empty WSDL

Dec 28, 2010

Using C#, ODP.NET and ASP.NET Web Services:

ClassA is a custom class generated from a "type" in oracle database.
ClassB is a custom class generated from a "table of type ClassA" in Oracle database.

The exposed service includes a login procedure which gets a username as input parameter and returns object B. Debugging the login procedure I can see that the data is retrieved from the database but not printed in the wsdl..

[Code]....

My ClassB definition is as follows:

[XmlInclude(typeof(ClassB))]
public class ClassB : INullable, IOracleCustomType, IXmlSerializable
...

similar definition holds for ClassA as well. the generated wsdl is :

<? xml version="1.0" encoding="utf-8" ?>
<ClassB xmlns="http://tempuri/org" />

and no data printed out. What may be the problem?

WCF / ASMX :: Web Service - WebMethod Accepting Custom Object?

May 11, 2010

I have a custom class declared as follows (in vb.net)

<Serializable()> _
Public Class NumInfo
Public n As String
Public f As Integer
Public fc As char()
Public t As Integer
Public tc As char()
Private validFlag As Boolean = True
Public Sub New()
End Sub

I also have public properties(read/write) for all the public variables

End Class
In my service.asmx codebehind class I have a webmethod as follows:
<WebMethod> _
<XmlInclude(GetType(NumInfo))>
Public Function ConvertTo(ByVal info As NumInfo) As String
Return mbc(info)
'mbc is another function defined in my service.asmx "service" class
End Function

The problem is that when I start debugging it to test it, the page that I get does not contain any fields where I could input the values for the public fields of numInfo. How do I initialise the class? There is no "Invoke" button either. All I see are soap details as below:

ConvertTo
Test
The test form is only available for methods with primitive types as parameters. SOAP 1.1 The following is a sample SOAP 1.1 request and response. The placeholders shown need to be replaced with actual values.
POST /BaseConverter/BaseCon.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://RohitServices.in/ConvertTo"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ConvertTo xmlns="http://RohitServices.in/">
<info>
<n>string</n>
<f>int</f>
<fc>
<char>char</char>
<char>char</char>
</fc>

What am I doing wrong? For the record I tried replacing char() with string to see if it was the array causing problems but that didn't help either. I'm fairly new to web services. I tried replacing the custom object parameter with a primitive parameter just to check how things worked and it rendered a page with an input field and invoke button. I just can't seem to get it working with custom object.
