Asp – How to share a variable from sub routine to sub routine

asp.netvb.net

I have a sub routine where I pull in information from a database. I want to use variables from this sub routine in another sub routine. I tried making everything public but it doesn't want to be friendly and share. 

Dim strEmail as String
Public Sub readDB()
strEmail = "whatever@doohikcy.com"
End Sub

Public Sub submit_btn(ByVal sender As Object, ByVal e As EventArgs)
Response.Write(strEmail)
End Sub

The readDB would read the database and set the variables and do whatever it needs to do. Then when they submit the form it would e-mail the form to whatever the email address was.

Best Solution

Every time an asp.net page loads, the global variables are wiped out. You can avoid this by using Session variables.

Public Sub readDB()
   Session("strEmail") = "whatever@doohikcy.com"
End Sub

Then:

Public Sub submit_btn(ByVal sender As Object, ByVal e As EventArgs)
    Response.Write(CStr(Session("strEmail")))
End Sub
