If you are working with a web app I'm not sure a global dataset is the solution. You are going to have all kinds of problems when multiple users access it at the same time. A global variable in a web project is a single variable for everyone who uses it...not a variable for a single user on a single session. I would suggest that instead you make a global method to run queries/procedures to your database. In these global methods you can include the code to open and close a single connection so you will always be sure to only have one open and you will not leave it open when you are not using it.
I hope this helps.

Hi to everyone,
I'm writing, maintaining and deploying some applications: every aplication is made up by an executable (winexe) and some dlls (class library). To distribute them, I generate a Setup program for each application using the standard Setup project included in Visual Studio 2003.
Everything used to work fine but, a couple of weeks ago, the generated Setup for one application "lost" one library: it was simply missing from the .msi file and I had to include manually into the project to force the installation. Last week another Setup "forgot" three assemblies.
I also wrote a little vb.net program to scan - through reflection - all the referenced assemblies in the winexe and copy these assemblies in another folder and actually I found out that the same assemblies were missing from the new destination folder (but still there in the bin directory)
Given that:
- each application has all the references to the assemblies, with LocalCopy=True (indeed, I can find them in the bin directory)
- each Setup project is in a different solution than the application
- each Setup project is SourceSafe'd
- each assembly (winexe and library) is obfuscated and strong-named
- I checked version and date properties for the missing assemblies and they were coherent with the application (same version and date/time)
am I doing something wrong (or missing something important) or did?
Thanks in advance to anyone will help.

System.IO.Directory.GetDirectories
takes a search pattern as a parameter.
System.IO.Directory.Delete
takes a path to delete. You don't need the DirectoryInfo class.

Give this a try
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim folderDate As Date 'Holds the date the folder name represents
'Loop through each folder under a given directory
For Each dir As String In IO.Directory.GetDirectories("c:\test")
'Try to parse folder name to valid date
Date.TryParse(IO.Path.GetFileName(dir), folderDate)
'If folderDate is less then Date selected, then remove it
If folderDate <> Nothing AndAlso Date.Compare(folderDate, DateTimePicker1.Value.Date) < 0 Then
IO.Directory.Delete(dir, True)
End If
Next
End Sub

I would like to, by example, choose the network I connect to by SSID, be able to know the WiFI stength signal, ...
Is there any existing object on the ConpactFramework giving me this ability ?
Thanks for your help,

When You send any item to right list box then remove it from left listbox
and move it right to left then remove it from right listbox
with this code
listbox2.items.remove(listbox2.selecteditem)
Thanks & Regards
