I am trying to display selected file to a user right after he selects. Which means I have to save it to a temp location and change image src (or ImageUrl if we are talking about asp:Image).
And I am trying to use AsyncFileUpload (from Ajax Toolkit) for that. Apparently it has "OnUploadedComplete" server event, but sadly it isn't working.
I have following code in code behind:

I have a really weird problem that I've been investigating for at least one week now. I deliver a website hosting both ASP classic and .NET 3.5 content in IIS6 on a Windows 2003 server environment with MySQL db backend. The solution has been installed on several servers (some hosted in WMWare) with no problems. On one specific server, also hosted in WMWare, the user experience great performance issues on the website. The problems are most seen when using database resources and is not limited to either .net or asp classic, but I am still not sure that the problem is only related to database calls.
Following components are involved:
IIS6 .NET FW 3.5 MyODBC 3.51 / 5.1 MySQL 4.x
Code executed on the server using all resources above runs smoothly when the IIS is not involved. The website shows times up to 2 minutes to execute code that takes 2 seconds outside the IIS. The exact same code is executed. Using profiling tools, I've seen that the great loss comes within calls to unmanaged code, for example when System.Data.ODBC namespace to calls into myodbc.dll.
The tricky part is: If at least one console user is logged in to the server, the performace problems are not seen anymore. When the user logs out, the problem appears again.I have tried to reinstall all components above, tried different versions of MyODBC, tried different website authentication methods, tried to run website under administrator privilegies, installed various MS KB's with no success.

I need to display the contents of a file selected from a ListBox into a text box. When I populate the ListBoxItems, I set the Text property to the name of the file and its full path to the Value property.
When I click the item, the page refreshes because AutoPostBack is on, but nothing happens. I then tried this:
VB.NET Code:
Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged Me.txtServiceTag.Text = Me.lbLogs.SelectedItem.TextEnd Sub
But it still didn't work.
after i can copy my file to another folder i realised that if this webapplication is used by multiple users at once, then some users are going to get locked out because each one is trying to copy those files.
so how do i tell the user thats trying to use a file to wait untill the file is available.
StreamWriter WriterTotxt = new StreamWriter("date.txt", false);
DateTime LastAccess = File.GetLastWriteTime("path.dbf");
WriterTotxt.Write(LastAccess);
WriterTotxt.Flush();
WriterTotxt.Close();
string ReadTextFile = File.ReadAllText(txtFile);
DateTime test = Convert.ToDateTime(ReadTextFile);
if (File.GetLastWriteTime(LatestUpdatedTime).CompareTo(test) > 0)
{
File.Copy(Path.Combine(sourcefile, fName), Path.Combine(destinationfile, fName), true);
}
I want to get full path which user selected in file upload control.
how can we do it.
I'm attempting to change my select statement when a selection of "Other" is detected. The problem is that the select that executes on the page is always the original selection from the datasource definition. I've found an example where the "SelectCommand" value is changed in the code behind, but it is for a case where the dropdownlist is not in a template. I'm thinking that I have to bind to the template, but I'm not getting it to work. (see the last couple of lines in the Page_Load code)
asp code:
<div>
<asp:DetailsView AutoGenerateRows="False" DataKeyNames="EmployeeTimeId" DataSourceID="sdsEmpTimeDetailsView"
DefaultMode="Insert" HeaderText="Add EmployeeTime"
runat="server"
AutoGenerateInsertButton="True"

using vs2008, asp.net, c# .net3.5 In this control;s ActiveTabChanged event, the ActiveTabIndex property stays 0 no matter which of the 3 tabs I select. Why is that? I want to keep track of which tab the user has selected and store this in the seesion variable so when refresh or bookmark by the user is would done properly. I was advised to possibly do this by saving the ActTab instead of the ActiveTabIndex. The problem then is how do I set the ActiveTab of the Tabcontainer, I mean how do I cast the Seesion variable so I can assign it like tabScien.ActiveTab = (castType)(Session["SavedActiveTab"]);

Question:
I have a web interface where a user can upload an XML file, which then gets imported into a SQL database.
Import works fine, interface works fine, logfile works fine. The problem: The user doesn't get any progress report until the entire file has been processed... Is there any way the server can output logfile messages to the user page while processing? I mean AJAX doesn't work for server side calls to the client, only vice-versa, or is there a workaround ?
Is there any possibility to remove the message "no file selected" from the AsyncFileUpload control ?
My users are confused by this message, because it shows after they succesfully uploaded a file.
