The Problem is you are not setting the connection or command type of your select command. Add these two lines right before you execure the reader
<br />
selectCommand.Connection = conn<br />
selectCommand.CommandText = CommandType.Text<br />
Hope this works

Well, we have no idea what you can handle. Have you done any study ? Read any books ?
Do you know how to work with a database ? If so, how about a CD list web app ? That's nice and simple.

A guestbook is a good beginner project. It contains the simplest form of the basic principles for most web applications; data entry, storage and retrieval.

Hi TC,
Your problem description is a bit vague. Do you just need confirmation from the user before the process can continue, or do you want to run two processes at the same time, one of which should ask for confirmation while the other one just continues?
Regards,
Johan

NO - if you want a message box on the client, Jscript is the language that runs on the client.

hi all:
how the bold code suppose to check if the fsi(FileSystemInfo object)
contain file or directory ??
its working fine but i want to understand how ??
Sub DisplayFileSystemInfoAttributes(ByVal fsi As IO.FileSystemInfo)
' Assume that this entry is a file.
Dim entryType As String = "File"
' Determine if this entry is really a directory.
If (fsi.Attributes And FileAttributes.Directory) <> 0 Then
entryType = "Directory"
End If
End Sub

The And operator ( && in real programming languages ) returns true if the value on the right is also contained in the value on the left. In other words, if Directory is 0010 in binary, then 0011 and 0010 will both return true, 0001 will not.

If Directory is a number ( and, as an enum, it is ), and it's binary representation is 0010, then the collection of values represented by 0010 and 0011 will both contain the Directory value, and will so both return true when Anded with Directory.

ok... but why the coder choose to add the value of the file attributes
to FileAttribute.Directory(10000)
example of directory
10110 and
10000
------
10000
example of file
100000 and
010000
------
000000
why is both cases we have to add the value(10000)

You're not adding, you're comparing. The AND operator returns true if a flag is present on both sides.
