Storing a Value

[vellaima]

Is there anyway of storing a value which is available thro' out the forms in VB.NET.

Yes, declare it at the form level rather than at the procedure level. Look up variable scope in the help files.

use a session state
the session state would look like this
Session("Name") = TextBox1.Text

then the other pages you would import the class

Imports SessionStates.WebForm1
SessionStates is the project
WebForm1 is the class

then you will call the session
Label2.Text = "Hello " & Session("Name")

wayko, I think he ment Windows Forms. (not sure)

 

[vellaima]

Yes. I meant Windows Forms.

 

[vellaima]

Can we implement SessionState in Window Form. Please do help me.

 

[divil]

A Session is an ASP thing. If you want to persist data across forms, you can do so with variables, as I said.

If you don't understand this, can you give us a broader understanding of what you're trying to do?

 

[Robby]

No you can't.

When the user logs into an application i would like to maintain his user_id thro' out the Window forms .

We do this with our own custom SessionToken object that we use to pass between forms and tiers. I suppose if you had some assembly that all your tiers reference, like a SystemFramework, you might be able to get away with it being all public shared properties of an object in that assembly.

I think you guys likely know what he's getting at. How do you maintain your session data across forms and tiers?

In this case I would just use a Public Property to Get/Set the UserID.
