I need to convert .NET data to XML types and viceversa and I wonder if there is any class already on the .NET framework to do it. UPDATE I want to perform a data type conversion.

I have an application that allows admins to add types such as document types and training types that are in seperate tables with a foreign key in a transaction table.
When structuring my class I decided to go with an abstract-like pattern (without the factory methods though). So I have a Type abstract class that defines my Save, Delete, and GetList methods. I have a training type class that inherits this class. The thing is all types have 3 main properties - defined in the abstract base - but have different source tables and thus different store procedures in my DbCommand object. So basically I repeat setting up the same parameters on all the derived classes. I would like to implement the common stuff in the base but I am getting thrown off by the difference in data sources.
I am confused that predefined datatypes like String,Integer Int32 etc. are Class or something else? Since there symbols that appears through intellicence are different than other classes. The predefined datatypes have different Symbols than Classes. What could have been written inside those datatypes?
View 14 RepliesUsing the following Webservice definition using aClientArgs as a complex type:
[System.Web.Script.Services.ScriptService]
public class Controller : System.Web.Services.WebService {
[WebMethod]
public void save_client(aClientArgs client)
{
// Save client data
}
}
Then defining aClientArgs as a sub-class:
public class aArgs
{
public string id = null;
public string name = null;
}
public class aClientArgs : aArgs
{
public string address = null;
public string website = null;
}
Returns the following WSDL fragment for the save_client args:
<save_client xmlns="http://tempuri.org/">
<client>
<address>string</address>
<website>string</website>
</client>
</save_client>
When I'm expecting the following:
<save_client xmlns="http://tempuri.org/">
<client>
<id>string</id>
<name>string</name>
<address>string</address>
<website>string</website>
</client>
</save_client>
So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?
I need help writing a class that will contain three values per item. I'll be passing parameters to a report: Parameter Name, Data type (int, string, date, etc), and Value. When I pass those values to the report using the class they should be in original form (i.e. an integer should be a numeric, a string should be a string, etc.).
I can do it converting the data's value to strings on one end, and reconverting to the original data type on the other, which seems like a lot of runaround. Is there a simple way? Also, if I'm able to store & retrieve the data in it's native format I don't need the "Data type" stored.
This is the error i'm getting while try to view class diagram,any suggestion.Some of the seleced types cannot be added to the class diagram.Checks the code for errors and ensure that all required assemblies are referenced.

I have a Solution that has two class libraries. I'm trying to convert the whole solution from asp.net 3.5 to 4.
Right now the libraries are in my Visual Studio 2008 projects folder. I've installed VS 2010. Should I just copy the libraries from the 2008 project folder to my 2010 project folder and open them in VS 2010?
What is the best practices for this? The entire solution is in a single folder in my VS 2008 Project folder, and each application and class library is in their own subfolder.
Without having to use logic to do this, I would like to store the names of Classes as Strings in one of my Database tables. When I retrieve the String from the table, I would like to some how use the string to make reference to the Class?
For example.
I store "Class1" as a string in my table.
I retrieve "Class1" as a string from my table.
I (somehow) convert the string "Class1" so it is usable in such an instance as...

I m Using a GridView: Columns: "Ser_type" tells what type of data is it i.e. VC for Varchar, NU for Numeric, DT for DateTime etc, for the time being i m using datavalidation controlls at design time. this is not a good approach. I just wan to do is that, DataValidationControlls should be created at RunTime and TextBox should validate data at runtime only. i.e. if Data required in the TextBox is of Type VC then it should validate only at runtime, if DT then validate DateTime only at Runtime similarly for all dataType:

I have IEnumerable object with value1 and value2. value2 is an array and value1 is string. I want to databind this object to Listview like that. So both value1 and value2[0] (always first item in array) could be accessed via <%# Eval("value1") %> and <%# Eval("value2") %> .
How to write expression to handle both items ?
ListViewItems.DataSource = f.Items.Select(t => t.value1, t.value2[0]);
ListViewItems.DataBind();
Both of these used same function. So why these two have been provided?
Secondly Why there is Not a constructor like:
String abc=new String("Hello");
Well i am just trying to test interoperability between ASP.net And Java web services, wanted to know what are the INTEROPERABILITY issues concering DATA TYPES that are there between the 2?

View 2 RepliesI've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert.

Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.

In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?

View 1 RepliesI am getting ready to just write my own, but I have a need for some regular expressions that will validate strings to make sure they are in an acceptable format to be inserted/updated into a database field.

View 3 RepliesIn my ASP.NET MVC 2 web application, I allow users to create custom input fields of different data types to extend our basic input form. While tricky, building the input form from a collection of custom fields is straight-forward enough.However, I'm now to the point where I want to handle the posting of this form and I'm not certain what the best way to handle this would be. Normally, we'd use strongly-typed input models that get bound from the various statically-typed inputs available on the form. However, I'm at a loss for how to do this with a variable number of input fields that represent different data types.A representative input form might look something like:
My date field: [ date time input
control ]
My text field: [ text input
field ]
My file field: [ file upload
control ]
My number field: [ numerical input control ]
My text field 2: [text input field ]
etc...
Ideas I've thought about are:Sending everything as strings (except for the file inputs, which would need to be handled specially).Using a model with an "object" property and attempting to bind to that (if this is even possible).Sending a json request to my controller with the data encoded properly and attempting to parse that.Manually processing the form collection in my controller post action - certainly an option, but I'd love to avoid this.Has anyone tackled an issue like this before? If so, how did you solve it?Update:My "base" form is handled on another input area all together, so a solution doesn't need to account for any sort of inheritence magic for this. I'm just interested in handling the custom fields on this interface, not my "base" ones.Update 2:Thank you to ARM and smartcaveman; both of you provided good guidance for how this could be done. I will update this question with my final solution once its been implemented.
have a table that keeps track of customer data that is beyond the scope of the Membership Class, this table I am also using the Membership.CreateUser() generated user ID.When I use my INSERT statement however to create a new row in my table I keep getting the Specified cast is not valid error.This is my SQL Command (The ...refer to other fields)
