Hi, I have some eventhandling written in VB.NET that I have trouble translating to C#. Anyone out there that can help me with this?
** UIController class **********************************************************
-- event --
Public Event ExitApplication()
-- function --
Public Sub ExitApp(ByVal sender As System.Object, ByVal e As System.EventArgs)
RaiseEvent ExitApplication()
End Sub
**************************************************************************
** WinForm class ************************************************************
-- field --
Private controller As UIController
-- in Form load --
Me.controller = New UIController(Me)
AddHandler controller.ExitTheApp, AddressOf Me.FormMainExit
-- function --
Private Sub FormMainExit()
Me.Close()
End Sub
**************************************************************************

Hopefully the site you found is good.
Otherwise, here's the conversion produced by Instant C# (I added class headers, etc. to get it into somewhat compilable VB format first):
internal class UIController
{
public delegate void ExitApplicationEventHandler();
public event ExitApplicationEventHandler ExitApplication;
public void ExitApp(object sender, System.EventArgs e)
{
if (ExitApplication != null)
ExitApplication();
}
}
internal class WinForm
{
private UIController controller;
private void FormLoad()
{
this.controller = new UIController(this);
controller.ExitTheApp += new System.EventHandler(this.FormMainExit);
}
private void FormMainExit()
{
this.Close();
}
}

Dear All,
i have developed a desktop based application using C#.NET, which require access to some USB based devices.
I have to use this application on target PCs in which the USB port is disabled by the system administrator.
From the application, i wants to enable & disable the USB drives programatically, so that no other application can use the USB ports, as per configured by the system administrator.
ie, enable the USB port before the application require access to the USB port it & disable it after the use.
I need to achieve the same when the application is running in a login, who doesn't have administrative rights.
Is it possible to achieve the same using .NET framework?
Do any one knows how to implement the same. If so, please inform me.
Best Regards,
Abhilash Chandran

Thank you for ur reply.
But, my requirement is slightly different.
My application has to run on a system in which the USB ports are disabled by the system administrator.
From my application i have to enable the USB drive, so that only a particular USB device must be able to use the USB drive. My application uses this USB device & finally when the application finishes using the USB device, i have to disable the USB drive again from the application.
All the above actions i have to perform in a non adminisrator login.
If you have any information regarding the same, plz let me know
Best Regards,
Abhilash

I am doing a project in .net c# 2.0 with sqlserver2005
i have a listbox in the form in which i need to display some data from database.
i need to get the loginnames of those clients who have levelid= 2 and 3, and who r logged in.
For levelid and logindatetime are stored in 2 different tables 'login' and 'dealerlogin' respectively.
Now to get his data i queried (in sqlserveranalyzer):
select loginname from login as a, dealerlogin as b where ((b.levelid = 2) or (b.levelid = 3)) AND ((a.logindatetime is not null) and (a.logoutdatetime is null))
But there is some error. There is some problem in joining the 2 diff. clauses of 2 diff. tables.
How can i do this?
Hope to get a reply.
regards nekshan.

How are the two tables related? You are missing a part of your where clause, the part where you must specify a.[Some Column] = b.[Some Column]

Can you please give me a regular expression in c# to remove single line comments from a string and its urgent
Criteria
a. // text --- Should be removed
b. file:///text.txt -- should be retained
c }//abc -- hear //abc should be removed
Thanks in Advance
Thanks and Regards
