Hello EveryBody.
I am new in Nhibernate with Asp .Net.

MyFolder Structer is
in D Drive :
D:\online\OES
in this some folder like
OES.DAO---it is a Class libabrary
OnlineExam---It Is website in Asp .Net
and My solution File OES.sln

Tecnology used is VS2005,Nhibernate,Asp .Net,AJAX
I develope A Arcitectuer in which two layer .
One is website layer and one is my Class libarary whic name is OES.DAO.
OES.DAO CONTAION ALL BUSINESS logic.

OES.DAO CLASS LIABARY CONTAION SOME FOLDER

ONE OF THEM IS
1.dblayer: it contaion one class
which code is

Code:
using System;
using System.Collections;

}
}

Here I Got Error sessionFactory = new Configuration().Configure().BuildSessionFactory();

2.Thesecond FOLDER in OES.DAO IS businessobjects
WHICH CONTAION the all classes which map the database Tables.

Now In My Fisrt Layer whic name is OnlineExam [It is website] and My Solution File name is OES.

The Mapping hb.xml Files in dbmappings Folderls which map Database tables one of then is
AnswerToMCQuestion.hbm.xml

Code:
<?xml version="1.0" encoding="utf-8" ?>

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
namespace=" OES.DAO.businessobjects" assembly="OES.DAO" >
<class name="AnswerToMCQuestion" table="tAnswerToMCQuestion">
<id name="Id">
<column name="cId"/>
<generator class="uuid.hex" />
</id>
<property name="CreationDateTicks">
<column name="cCreationDateTicks"/>
</property>
<property name="IsRightAsInt">
<column name="cIsRight"/>
</property>
<property name="AnswerText">
<column name="cAnswerText"/>
</property>
<property name="NumInOrder">
<column name="cNumInOrder"/>
</property>
<many-to-one
name="Question"
class="MultipleChoiceExamQuestion"
column="cQuestionId"
not-null="true"/>

</class>
</hibernate-mapping>

Now The main Thing is Web.Config file setting where I got Error bz i dont know how to Map these .HBM.XML File here and how i give The Path bz My Business logic table which map the database tables in OES.DAO layesr .

This looks messy. VERY messy.

Why don't you build the image from a memory stream constructed from the bytes that you can access from the upload control ? As for the rest, I'm not sure what to suggest.

Can we create a new image with the uploaded image using with memory stream. i want to create a new image, with new size and add watermark in this image. if we can do these things with memory stream can i get some ideas(sample codes)

MemoryStream ms = new MemoryStream(upload.Bytes); // Whatever it is, intellisense will tell you
Bitmap bm = Bitmap.FromStream(ms);

That's it. You have a bitmap and you can do what you like to it.

Also,My eyes are wide open and u need to open your mind little bit.

if you want to use template field in gridview do something like

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="Test1">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Test2"></asp:TemplateField>
</Columns>
</asp:GridView>

Thats a pretty dumb thing to say, considering if you read your original post carefully you cn clearly see that a bunch of asp: tags are missing their closing tag.

And the moron of the day goes to the guy who can't work out what a 'server tag is not well formed' error means, and who goes on to abuse people who try to give him free help. Congratulations. I suggest a career change.

The Label,text box are not properly closed

First you should post your complete code, don't tell "its not showing...".

The Eval Code is like the below one

<asp:Label ID="lblCategoryName" runat="server"
Text='<%# Eval("CategoryName") %>' />
