You've been extremely helpful, and I thank you for your patience with me =)
I will give the code a run and let you know.

One simple solution to this is have the SessionClosing event be static to the class. The class could simply maintain a static variable that indicates if it's ok to shut down, which the instance class can set to true/false (and of course you can get as complex here as you like, including other variables to explain what's going on, etc.).
Then, the handler can be wired and unwired in the main application code where Application.Run is called, instead of needing to do it inside the form. This way, you don't need to worry about the form's lifetime, only your application's.

And you can go back to the original requirement and scrap all this SessionEnding crap and maintain database consistency with transactions. So what if Windows shuts down before the app is done?? What if the power fails??

... What are you on about? You seem to be upset about something and I'm not sure what you're actually saying/asking here.

No, it's just another situation I thought of at the very last minute. My brain has been fried all day...

No problem.. I know the feeling. I've been battling a stupid databinding problem all day..

Well, the code worked. Thank you!
However, I found what was causing me mass frustration. The code works perfect in XP (which is the platform I need it for), but on Vista, it always brings up that End Task box. Apparently MSDN says Microsoft added that on purpose for Vista...
I hate Vista.
Thanks for all your help

Is it possible to copy the data in a DataGridView column into an array without using a loop? I was hoping that there was, and that it might be perhaps faster than a loop.
Thanks in advance

No. You have no choice but to enumerate the cells you need from wherever the data is being kept and copy them to any array.

I have to execute an application (ie: c:\applications\task1.exe). I have to send some different commands and wait for the responses. Some responses are fast and has only few lines, some will take long time to execute but response every second with a dot until it completed
I would line to send command line through VB environment (might be with Shell (...) command?), but able to capture the responses without waiting it completed (to monitor its processes)
Anyone can show me how to do it?
Many thanks

There's a bunch of code behind that. But, you're launching the process with the Process class, then redirecting the StandardInput and StandardOutput streams so your code can capture the output of the console app.
I don't have an example handy because I'm walking out the door right now...

Here is an example, which executes the "cmd.exe" (command line executable), gets a directory listing, and displays the result in a messagebox:
Dim ps1 As New Process
ps1.StartInfo.FileName = "cmd.exe"
ps1.StartInfo.WindowStyle = ProcessWindowStyle.Normal
ps1.StartInfo.CreateNoWindow = False
ps1.StartInfo.UseShellExecute = False
ps1.StartInfo.RedirectStandardOutput = True
ps1.StartInfo.RedirectStandardInput = True
ps1.Start()
Dim s As String
Dim sIn As StreamWriter = ps1.StandardInput
Dim sOut As StreamReader = ps1.StandardOutput
sIn.AutoFlush = True
sIn.Write("dir /p" & System.Environment.NewLine)
s = sOut.ReadToEnd()
MessageBox.Show(s)
Don't forget to "Imports System.IO" for this. I hope this helps.

Thanks, I also hope so, but I got errors on Dim sIn As StreamWriter (not defined). might be I need add some kind of Import?

Correct. At the very "TOP" of your Windows Form, type "Imports System.IO". That should fix your problem.

Hi Pete,
Thanks for the reply, however when I try to run as it is (without compiling error), it launches cmd (ms-dos window) empty then stays there forever until I close the ms-dos window then it shows the responses ( MessageBox.Show(s) )
I do not know why I have to close the ms-dos window manually, can we close it automatically?
Thanks

Its because of this statement:
s = sOut.ReadToEnd()
Take that line out and it will close the DOS screen on its own.

What you can do is to either compile the C++ project into a DLL and add a reference to it in VB.NET, or you can convert your C++ project to VC++ .NET project and add a reference to the whole project.

Hi,
I made my download manager in VB.Net but I don't konw how to set it as default for IE 6 and also for IE7 ?
Any idaes?
Thanks,
Dan

There is no Download Manager in IE, so no way to set one.
|
|
|
|

I think I need to explain more. I have created the download manager like flashget,freedownloadmanager,Getright and the other ones... They all have the option to set them in ie as default so when a download begins the ie show thier interface instead of its' orignal.I want to do same thing.
|

I don't know how it does it, but IE doesn't have this "option". Maybe if it was written as a AddOn to IE you get this ability. I can't tell you because I've never written anything for IE.

Hi,
Yes IE doesn't have any options but we can do it using some registry help.I think I found the perfect answer from this link : http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2154635&SiteID=1
Thanks,
