Apparently you haven't, because not only does it work, but it's the ONLY thing that works. What makes you think it doesn't work ?

Hi!
Hmmm... I think I know what you mean. Try using ShowDialog() instead of Show() when you are opening your window in your code. That Should work.
Forgive me if I misunderstood your question.
Thanks!

As suggested by The JZ, use the TopMost property.

I am Using Vb.net 3.5 as Frontend
I am creating a Windows Application.
I am Using a thread 'ThradSend' that do some work, I am starting thread as 'ThreadSend.Start()' and ending the thread ThreadSend.Abort()
It will work fine in my application but Throws an exception that 'Thread was being aborted. at System.Windows.Forms.dll ...'
This will no hampered my code but still a error a message displayed.
How can I Stop this Problem Or How can I Stop a running Tread . I can't use Thread.suspend() because it says Obsolute.....

The Abort method stops the thread by throwing a ThreadAbortException in the thread. For this to work properly your thread has to be written to support this. As it doesn't catch the exception and handle the situation, it isn't supporting this.
The easiest way to stop a thread is to make it stop itself. Use a synchronised variable that the thread checks periodically. When you change the variable, the thread should just end it's loop and exit.
Despite everything, the person most likely to be fooling you next is yourself.

What do you want your program to do when a plug and play device is detected?
|

Hey,
You could count the number of logical drives (using a timer), store that value in a variable and keep comparing the new and the old situation. When it's different, you know a swappable drive was plugged in. Note that this won't work in all situations and that many things cán go wrong
Motivation is the key to software development.

I don't think anyone here wants to do your project or homework for you. How about starting with a Google search: detect a network sniffer[^]

That is what your graduate adviser is for. Ask him or her for help.

Hai all,
if your program store a user password, where you normally tore them?
i.e. registry, ini, text files etc.
|
|
|
|
|
if your program have multiple user then i prefer to store it in database( like MSAccess, SQL Server etc.) or if your program have only single user then you can store in any way like in text file, XML file, registry , database or even in code(bad option). you can also store user name and password in registry in encrypted form
|

Hai swami,
Thanks a lot. so i preferre to store it in the registry under my programs key. i have only two other values for my programs. so with the password, then only 3 values. so is it ok to store the password in a value call "user_password" and the data is the 31bit encrypted password.
will this value name "user_password" ok or still i need to put a junk name for the value?

choose some different name for key so it seems like the key of Windows OS key

I'm not sure this is the correct place to post but since I wrote the code in vb I figured I would start here. I have a service that I created that writes to a text file, but it only writes 16 times and then stops. I have not asked it to stop it just does it on it's own. I am using this for testing because I have a bigger project that I need to create as a Window service and the timer wasn't working in it. So I created this small testing project and still can't get the timer to work correctly. Could some one please give me some clues as to what might be wrong with the code? I copied below what I am using.
Public Class AuthorLog
Protected Overrides Sub OnStart(ByVal args() As String)
' Add code here to start your service. This method should set things
' in motion so your service can do its work.
Const iTIME_INTERVAL As Integer = 15000 ' 15 seconds.
Dim oTimer As System.Threading.Timer
Dim strline = vbCrLf
System.IO.File.AppendAllText("C:\AuthorLog.txt", "AuthorLogService has been started at " & Now.ToString() & vbCrLf)
Dim tDelegate As Threading.TimerCallback = AddressOf EventAction
oTimer = New System.Threading.Timer(tDelegate, Me, 0, iTIME_INTERVAL)
End Sub
Protected Overrides Sub OnStop()
' Add code here to perform any tear-down necessary to stop your service.
End Sub
Public Sub EventAction(ByVal sender As Object)
System.IO.File.AppendAllText("C:\AuthorLog.txt", "AuthorLogService fires EventAction at " & Now.ToString() & vbCrLf)
End Sub
End Class
Thanks for your assistance in advance.

It probably stops when the oTimer object get's garbage collected, since it's no longer in scope when your OnStart method gets to End Sub. Using a Timer to run a service is pretty much bad practice. You normally use the OnStart method to setup and start a new Thread containing your service code.

I am really not understanding the reply. I thought timers were used in services to set how often it should run. Could you explain how a service would be set up? Everything I have researched and looked up on services shows the setup like I have in the code snippet above.
Thank you.
