How to create and use assemblies in .net? can anybody explain me how to use assemblies?
|
|
|
|
|
|
in .net .exe & .dll files are known as assemblies
and u can make .exe by creating a windows application or console application etc..
and u can make a .dll by creating a class library
|
|
|
|
|
Add the the Assembly you want to use as a reference to your application and include its namespace and use it .....
If you want to create a assembly it depends on which tyoe of application are you devloping

I have three pages: First.ascx, Second.ascx and Third.ascx
In First.ascx, im setting a session variable to some value
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Session("xyz")="SomeValue"
End Sub
In Second.ascx, i have a function to access the session value
Public Function RetrieveFromSession() As String
Dim str As String
str=Session("xyz")
return str
End Function
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim SessionValue As String
SessionValue = RetrieveFromSession()
End Sub
This is working perfectly fine. Im able to access the session this way.
But in Third.ascx, im creating an instance for Second
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim objSecond As New Second()
Dim strSessionValue As String
strSessionValue = objSecond.RetrieveFromSession()
End Sub
The function RetrieveFromSession() is called properly, but inside the function
the line str=Session("xyz") goes to error. It says "Object reference not set to an instance of an object."
But, im able to access the session directly. ie.,
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim strSessionValue As String
strSessionValue = Session("xyz")
End Sub
This is working fine.
But, i want third.ascx to access the session using objSecond.RetrieveFromSession() function.
How can this be rectified.
Can anybody help me in this regard???

Hi,
Your approach is not correct. and it won't work at all.
When u set session value it will be accessible from current objects of all the ascx.
Here u r creating new object of second. When u do this a new session will start for that instace and that new session will not have any value obviously and that's why it is giving you error.
Its better that you access your session value by conventional way.
and I dont understand why you want to go by "objSecond.RetrieveFromSession()" this way.
Is there any specific requirement?
Thanks and Regards,
Chetan Ranpariya

Hi Chetan,
Thanks for your quick reply.
The reason for me to use objSecond.RetrieveFromSession() method is,
i want Third.ascx to perform an operation which is already done in a function in Second.ascx.
I dont want to write the same function again in Third.ascx.
I want to use the function which is already there in Second.ascx.
Since the function is accessing Session, it throws error.
Can u suggest any other way to do this without copying the same function from Second.ascx to Third.ascx.
Thanks & Regards

Create a class to access your session objects if this is what you require and reference this class from your pages. It's not good practice to have your aspx pages referencing each other in this fashion.
|
|
|
|
|
why don't u make a base class and derive your second and third class from that class
and in your base class u write the code to read the session
|
|
|
|
|
When you create an instance of a page class yourself, it's just an instance of a class, it's not connected to anything. If you call any methods in the object, it won't be able to use anything that is normally available in a page.
Put any code that you want to reuse in a separate class, and use that from both pages.

Hi,
Thank you all for your valuable suggestions.
I used the following code in the function objSecond.RetrieveFromSession()
before accessing the session.
Dim Session As System.Web.SessionState.HttpSessionState
Session = HttpContext.Current.Session
It worked. Now im able to access the session value this way by referring the current session variable.
Now i got two more problems in the same function objSecond.RetrieveFromSession()
1) Im not able to access the viewstate values of the base page. How can i access the viewstate through this function?
2) In my Login page ,i have set
FormsAuthentication.SetAuthCookie(strUserID, False)
Now, im not able to access the value by using
Page.User.Identity.Name.ToString() in the function objSecond.RetrieveFromSession()
But in the base page im able to acces it directly.
Plz suggest some way to solve this.

Hi,
You can use <asp:HyperLink> and set its Target property to "_blank" and its NavigateUrl property to the file url and done!!!!!!!!!!!!!!!!!.
I hope this will help you.

Hi,
You r right. I m suggesting you to use hyperlink control.
Thanks and Regards,
Chetan Ranpariya

Add the target="_blank" attribute to the link.
|
|
|
|

Are you trying to do this after a postback or from a regular link?
Regular link:
<a href="http://www.codeproject.com" target="codeProjectWindow">The Code Project</a>
Code Behind:
You'll need to register a client startup script to open the new window once the page has loaded:
<code>
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Page.ClientScript.RegisterStartupScript(Me.GetType, "codeProjectRedirect", "window.open('http://www.codeproject.com')", True)
End Sub
<code>
Hope this helps
