In a smart client application such as TaskVision
http://www.windowsforms.net/TaskVision/[^]
how does one implement single login?
In the current implementation, the application allows any number of logins using the same username and password. Could you please suggest how it can be modified to prevent login if there is a user already logged in with the same username and password? Or better still, to limit the number of simultaneous logins to a predefined number?
Keeping a login count in the database could be a solution, but is there a reliable way to know when a user stops using the program?
Can the constraint be defined in the stored procedure or in the web service(AuthService)?
Thanks.

i think u can use app.config file to add tag which hold the value of maximum user with same userID and password and if ur storing logged user info in DB then u can
check the user limit at the time of starting ur application.

I have two forms f1 and f2.
I have two buttons on f1, from button1 i am invoking f2 using the object of f2 and from button2 i am showing a simple message box.
My problem is, when i open f2 by cliking button1 and click on button2 to show message, when the message box is active i am unable to select f2, its understandable why f1 is not getting selected (message box is modal window), but why f2 is also not selectable?
I used another method to invoke f2, using threading concept, created new thread and invoked f2 in new thread in button1 click event. Now, i am able to select f2 even when message box is active. But when f1 is closed f2 should also get disposed?
Any ideas?
Thanks

I think you should create your own messagebox window (new form) and open that. I cannot think of another approach...

Thanks

I am creating application for controlling 8-channel Lightshow through LPT for a small club.
I want lightshow to work by sound input from soundcard. I don't know how can I create a function which would return current output power on the requested frequency(low,mid,high...).
I tried to do this with DirectX.DirectSound, but it seems to me too complicated.
So if anyone have a suggestion, i would be very grateful.;)
Thank you,
Miha

Hi
You can use xpath to query a specific node within a xml file.
Open a xml file in a XmlDocument object (System.Xml namespace) and then you can get its elements using xpath.XmlDocument has some methods that you can use to query a xml file for example you can use SelectNodes or SelectSingleNode or GetElementsByTagName.
You can use serialization to serialize and deserialize your xml file into an object model.You can use xsd utility to build this object model from your xml file the you can use XmlSerializer (System.Xml.Serialization namespace) to deserialize your xml file into your object model and use this object model to populate a treeview.
