Infinate Loop Problem
 
Hi Folks,

I'm trying to loop through my query results using datareader.

I want to create a submenu by checking the subtitle exists then concatenate the values.

  1. while (reader.Item("subtitle").tostring() <> "")
  2. submenu &= "<p>" & reader.Item("subtitle") & "</p>"
  3. end while

The page wont seem to load though, it must be a problem with the loop, do you know how I can read the next item?

Here is my comlpete code:

Code:

While reader.Read()

' set title

sitename =  reader.Item("sitename")


mydata &= "<p>" &  reader.Item("pagetitle") & "</p>"


'check for subpages then create submenu

    if  (reader.Item("subtitle").tostring() <> "")


    while  (reader.Item("subtitle").tostring() <> "")

    submenu  &= "<p>" & reader.Item("subtitle") & "</p>"

    end while

'concatenate submenu to main data

    mydata &= submenu

    End if
       
End while
