I am using the XMLSerializer to create an XML Schema. In one part of the XML, I have an element called 'parameters', which returns a collection of strings. The output is supposed to look like this:

How do I create a .xsd Schema file from a given .xml file programatically?
Is there a .NET class representing XSD.exe ?
i have to create a class that creates an xml file using a schema.i created a "Component class in vb.net and setted his properties with the tag xmlelement("nameofthexmlnode").i did the creation of the xml.Now i have to use the xml schema but i didn't found an easy to use/understand example.i know that i have to serialize the object but i can't still create an xml using a valid schema.

View 3 RepliesI need to have some of my columns in an integer value not string.So from I can tell so far and I am extremely limited, if I use WriteXml this should write the schema and the data and the readxml will read the schema and the data, although I dont see the schema in my xml file that gets created from my oDS.WriteXml/if I use oDs.WriteSchema I can view the schema file that is created. Thats how I determined the schema is creating all string vlaues for each column..All the fields are of String value as was pointed out, so how do i create my own schema file? or rewrite the one that is created.[code]

I have not yet tested this..but before I do that, I am just wondering, let's say you have a byte stream, and you want to deserialize that into an object?[code]...
View 3 Replies0I Have a vb6 application that uses .net objects via COM. When one of this objects calls code which instantiates XmlSerializer vb6 aplication crashes.Just this line fails: Dim x as new XmlSerializer(GetType(CustomClass))I agregate that these objects load assemblies dinamically but only it crashes over vb6 aplication. In .net 100% aplication this not happens.

I have a custom class that has one property as a collection.For some reason XmlSerializer doesnt like the class having a collection property and the Serialize Fails!If I remove the collection property it works! Is there a special way of getting the collection in the class to work?
View 1 RepliesI've been having problems with following code on some computers, while it's worked super on others (most):
Dim xmlSer As New System.Xml.Serialization.XmlSerializer(GetType(XMLContext))
which produces the stacktrace:
System.ArgumentNullException: Value cannot be null.
Parameter name: type
at System.Xml.Serialization.XmlSerializer..ctor(Type type, String defaultNamespace)
How can that code throw that exception, when the argument is drawn from a gettype call, and note that it doesn't happen when debugging on my own PC, only when it's installed on some of the client PC's???
I am trying to deserialize an Xml file content into a specific object. Everything runs fine but when I include empty tag of type date or time in my xml(having xsd that describes my xml structure) the deserialization fails. What can I do to make deserialization working when empty date tags are appear?
View 1 RepliesIs there any way to create an XmlSerializer that stores along with the serialized data the data type, then when deserializing, it automatically identifies the type of the serialized object and creates an object of that type (returned as object).
View 1 RepliesI have the following class which I want to serialize to XML:
[Code]...
I wish to put the XMLSerializer behind a 'facade' class of mine so that user wont have to supply type info to the constructor. But doing this has a problem. Consider this class:
Class XmlFormatter
Private Shared xs As XmlSerializer
Public Function Deserialize(ByVal serializationStream As Stream) As Object
Dim o As Object = Nothing
[code]....
The problem is that the user of this class cannot use Deserialize without first using Serialize because the XMLSerializer instance is created in Serialize and it is shared. But using Deserialize without this instance will simply return Nothing.
the schema is created using VS, but when I try creating the schema using XSD.exe, the validation works, am I missing something here, like namespace or anything?
SCHEMA:
<?xml version="1.0" encoding="utf-8"?>

elementFormDefault="qualified" xmlns="http://tempuri.org/EmployeeXML.xsd"

I have an imported sql database using pa as the schema instead of the default dboThe problem is when I go into vs 2008 and create a gridview control, it won't recognize the from table object. I get "invalid object name" unless I go directly into the code and put the database name and schema name in front of it.

I have an .XSD that is made from a class so that I can pass to a webservice. It got it over to the webservice as an XMLSchema object and now I need to make it into a class so that I can make objects out of it on the webservice side. I know that XSD.exe is the answer but I'll be darned if I can puzzle out exactly how to implement this thing. I need it to do this conversion at run time so I need to put the code for it into my project and all the references I've seen to using XSD.exe talk about calling it from the command line.
My .XSD is below.
<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="[URL]">

I'm a little stuck here and maybe some of you can point me in the right direction ... maybe even get me a solution. Well, I do query a table but before everything I need to get the SQL Query to create the Table (like you get, when you select to option "Create to" in SQL Server Management Studio).

There is an old timesheet application being used in my company and i am going to rewrite it in asp.net.There are other tables which can be linked to new Timesheet table like employee table but my main concern here is the Project and Project_Activity table.In the current system, there is a one project and a activity table which are linked to the timesheet table seperatly and user has to spend alot of time on selecting activities code they worked on for specific project.I have came up with the new idea; Project manager will have to fill up a project template and link all the activities code with the one project before starting this project. This way user will have to select the project only and it will automatically bring the associate codes for them.I like to know if this design will work okay? and is it okay to link Project_Activity table with timesheet?
