Question

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 = '[e-mail]' 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.

Answer 1

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') = '[e-mail]' End Sub 

Then:

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