hi,
can anyone explain if it is normal for the session variable to disappear after writing to a file. if yes what can i do (work around?) to make them persist even after writing to a file.
thanks.

No there is no reason why this should happen.
|
|
|
|
|
This should not happen
Might be session timeout or you are closing the session (unknownly)
Can you post the code What you have done while writing to file ?
<l>Thanks and Regards

here is the code:
when the user clicks the login button the following code gets executed:
Private Sub cmdLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdLogin.Click
' Attempt to Validate User Credentials using UsersDB from XML file
Dim accountSystem As New ProcessNowUser
if accountSystem.AuthenticateUser(txtUserID.Text, txtPassword.Text) Then
Session("UserID") = accountSystem.UserID
Session("DisplayName") = accountSystem.UserName
FormsAuthentication.RedirectFromLoginPage(accountSystem.UserName, False)
Else
Message.InnerText = "Sorry ! Login Failed. Please try again."
End If
End Sub
when the user clicks the change password button the function below is called and the new password is saved in the XML file. But when the page reloads the all session variables lose their value.
Private Sub btnChangePassword_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnChangePassword.Click
If isPageValid() Then
Dim changePwd As New ProcessNowUser
Dim sResults As String = changePwd.ChangePassword(Session("DisplayName").ToString.Trim, txtCurrentPassword.Text.Trim, txtNewPassword.Text.Trim)
If sResults.Equals("No Password") Then
ShowMessage("Password doesnot match!", Me)
Else
ShowMessage("Password changed successfully!", Me)
End If
End If
End Sub
Public Function ChangePassword(ByVal userName As String, ByVal OldPassword As String, ByVal NewPassword As String) As String
Dim returnValue As String = ""
Dim dvUsers As DataView = _dsDataStore.Tables("Users").DefaultView
dvUsers.RowFilter = "username='" & userName & "'"
If dvUsers.Count > 0 Then
Dim sPublicKey As String = dvUsers(0)("key")
Dim sEncryptedPassword As String = dvUsers(0)("password")
Dim sDecryptedPassword As String = Utility.DecryptTripleDES(sEncryptedPassword, sPublicKey)
If sDecryptedPassword = OldPassword Then
dvUsers(0)("password") = Utility.EncryptTripleDES(NewPassword, sPublicKey)
dvUsers(0)("key") = sPublicKey
updatexmlOnly(_dsDataStore)
returnValue = "OK"
Else
returnValue = "No Password"
End If
Else
returnValue = "No User"
End If
Return returnValue
End Function
Private Sub updatexmlOnly(ByVal ds As DataSet)
If IO.File.Exists(_sTargetDirectory & XML_DATA_DIRECTORY & "adminuser.xml") Then
IO.File.Delete(_sTargetDirectory & XML_DATA_DIRECTORY & "adminuser.xml")
End If
ds.WriteXml(_sTargetDirectory & XML_DATA_DIRECTORY & "adminuser.xml")
End Sub

Is this process taking longer than the session timeout (default 20 minutes)?

no, completes as soon as the button is clicked and the page reloads. but unfortunately, the session variables = Nothing

I'm really sorry for asking this as I'm sure it's something that has been solved many times before, but I must just not be using the right search terms to find the info.
I'm using ASP.NET 2.0 and C#. I'm using the treeview control and have it connected to a database and it works fine. It's kind of a FAQ page and the items in the treeview are links to an ID # of the topic that is passed to the page as an argument (page.aspx?id=3). The problem is that I can not figure out how to make the tree expand to the item. When the user visits the page, the menu is always collapsed. I would like to make the tree expanded to the item in the argument (id=3).
Hopefully I'm making sense. 
TIA!

hi
I too need the same functionality.
Is there any way to design/code an editable textbox without AJAX?
i need in ASP.NET 1.1 alone
|
|
|
|
|
You would need to write this functionality around the Javscript OnKeyUp event triggered by the search text box. This event would then need to process the textboxes content and perform the call event to get the data to be shown below the textbox.

Thanks Sam!
But i need to design/code it for a Dropdownlist in web application using Visual Studio .NET 2003

foreach (DriveInfo d in allDrives)
{
Console.WriteLine("Drive {0}", d.Name);
Console.WriteLine(" File type: {0}", d.DriveType);
if (d.IsReady == true)
{
Console.WriteLine(" Volume label: {0}", d.VolumeLabel);
Console.WriteLine(" File system: {0}", d.DriveFormat);
Console.WriteLine(
" Available space to current user:{0, 15} bytes",
d.AvailableFreeSpace);
Console.WriteLine(
" Total available space: {0, 15} bytes",
d.TotalFreeSpace);
Console.WriteLine(
" Total size of drive: {0, 15} bytes ",
