Could not load file or assembly 'Microsoft.Data.SqlXml, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
Am encountering this problem in the web .config

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

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">

</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 .

Some security error showing when i am trying to upload the image. it is working fine in the source code(Localy), but after uploading the page and trying getting the following error. Error is showing in the System.Drawing.Image Part.

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.

Close your tags properly.As i look your code,you have not closed textbox ,label,template and gridview tags

himanshu

plzzzzzzzzzzz read carefully mr. Himanshu..............each and every tag is closed..........plz open ur eyes

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.

look mr j4amie..............there may be some problem...........code didnt copied in Project Code properly.....and thats not my fault...okkk......thats why u were not able to see

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.

Man where have you closed the label and template tag.
moreover,your gridview template is completely wrong.

himanshu

that i did man..................may be when i copied it..............its not showing......its something related to EVAL code line.........do u have any idea......eval should be in single quotes or double quotes

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") %>' />

no, your code is not ended properly in so many tags....
