Calling a &quot;Final&quot; routine when application is ended by machine closing. HollenG22-Nov-04 7:32 HollenG 22-Nov-04 7:32  Does anyone know if you can have a routine run when your VB.NET or C# application is shut-down from the "Task Manager" or when the user shuts down their machine before they have closed your application? In other words is there a spot in a .NET application that runs no matter how the application is closed? I tried the "Closing" method of the "Default" form which I believe is the last thing to close when a C# or VB.NET appliation ends. My app has a "logon" status flag that I'd like to be able to reset for the user if they forget to close the app the normal way and just exit the machine from the "Start" menu with my application still running.

Have a look at the Application.ApplicationExit Event[^]. However as far as I know using then Process.Kill Method[^] on your application will abnormally terminate your process instantly without previously raising any events.

I'll let you know how the "ApplicationExit" event works. Scott Re: Calling a &quot;Final&quot; routine when application is ended by machine closing. HollenG23-Nov-04 6:59 HollenG 23-Nov-04 6:59  Dennis, Unfortunately "ApplicationExit" doesn't do the trick. Setting an EventHandler to it and having that event call my "log-out" code works if the application is killed through the "End Task" method of the "Task Manager" but it's not called through "End Process" of the "Task Manager" or when the machine shuts down from the "Start" menu. The same affect is also accomplished by putting the call to the "log-out" routine in the "Disposed" event of my "Default" form. I've looked into the "Environment" object but it doesn't have an "EnvironmentExit" event. Just and "Exit" method which obviously closes everything immediately. Any other ideas? Thanks for your suggestion. It looked like the way to go. Scott Re: Calling a &quot;Final&quot; routine when application is ended by machine closing. Dennis C. Dietrich23-Nov-04 15:09 Dennis C.

You couldn't expect that. When you click on "End Process" in Task-Manager it calls TerminateProcess[^]. That function forces all threads to terminate (for details on the different ways to end a process see also Terminating a process[^]). ...or when the machine shuts down from the "Start" menu. I can confirm that however I don't really understand why it behaves like that. Anyway, check out the Form.Closing Event[^]. Maybe that will help you to solve your problem.

What i have is a machine with SQLXML Virtual directories which created my WSDL for me. I access the storedprocedures through a soap call, once upon a time everything worked lovely jubbly. When service pack 2 politely installed itself it screwwed everything... IIS, SQL Server, anything else it could really. Now soap doesn't work at all get this error Run-time error '-2147024809(80070057) WSDLReader:XML Parser Failed at linenumber 0, lineposition 0, reason is: the system cannot locate the resource specified. HRESULT=0x1:Incorrect Function - WSDLReader:Loading of the WSDL file failed HRESULT=0x80070057: The parameter is incorrect. -CLient: One of the parameters supplied is invalid. HRESULT=0x80070057 The parameter is incorrect. Nuts, nothing has changed in anyway apart from SP2, i have tried re-installing SOAP Toolkit, SQLXML and porting it over to SOAP Toolkit 3.0. But NO!!!!! The last thing i should mention is i can't access the WSDL file through IE from this machine but from the machine it is on, it's fine, however i can access the other machine for everything else like files, etc..... Thanks for any assistance as i have been looking into this for days on end and i'm trying to avoid a re-install of windows. Thanks Purple "If i was king cigarettes would be free."

If it works after it, then you might consider setting your firewall configuration so that IIS & SQL will work with it... Good luck ! Registry Keys cwayman22-Nov-04 3:31 cwayman 22-Nov-04 3:31  Hey, I was wondering what registry keys are set when you right click on a printer and say 'Set as default printer' Thanks for your help Chris Re: Registry Keys Dave Kreskowiak22-Nov-04 3:37 Dave Kreskowiak 22-Nov-04 3:37  A simple search for "Setting default printer registry" on MSDN resulted in a nice little KB article: Setting the Default Printer in Windows 2000 by Using the Registry[^] RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome Re: Registry Keys cwayman22-Nov-04 4:42 cwayman 22-Nov-04 4:42  Hey dave, Thanks for the help, i am currently using that said method to set the default printer but some applications mainly MS Word and MS Excel do not recognise the new printer as default and use the previous one. I was wondering if any other registry keys where set on making a printer default as i think there must be a location that these applications are still looking to use the printer that they are. Any suggestions? Thanks again chris Re: Registry Keys Dave Kreskowiak22-Nov-04 6:51 Dave Kreskowiak 22-Nov-04 6:51  Actually, they both ask the system what the default printer is (Platform SDK: GetDefaultPrinter), not the registry. Both apps get the default printer only when they start or when they receive a WM_SETTINGCHANGE message. You might want to read this[^] and this[^] for a little more info.

It is one of many great tools offered by Sysinternals.

Your best bet is picking up a bunch of books, most of which are not going to target VB/VB.NET. Learn DirectX first, you might even learn a new language in the process.

So far I don't know much about DirectX but a good start is to make the Visual Studio recognize the DirectX libraries like. imports Microsoft.DirectX imports Microsoft.DirextX3D http://msdn.microsoft.com/en-us/library/ee416327%28v=vs.85%29.aspx[^] Re: Newbies Question :How to use DirectX in VB Dave Kreskowiak18-May-11 6:50 Dave Kreskowiak 18-May-11 6:50  Why are you replying to a post that's almost 7 years old??

I found a solution and I will share it here. It is very simple and worked with the DirectX11 ------------------------------------------------------------------------ Imports Microsoft.DirectX.AudioVideoPlayback Private dff as Audio dff = New Audio("c:/3.mp3", False) dff.Play() ------------------------------------------------------------------------ Re: Newbies Question :How to use DirectX in VB Dave Kreskowiak21-May-11 13:21 Dave Kreskowiak 21-May-11 13:21  Yeah, it'll work with just about any version of Direct 8 or 9, but the capabilities exposed by the Managed SDK only cover through DirectX 9. Anything beyond that and you won't be able to use it without writing a ton of interop code yourself.

I have created a custom trace Listener class, called "DBTraceListener" it works fine when i add it manually in code : (eg. Trace.listeners.add(new DBTraceListener("myDBListener", TraceLevel.Verbose, getDBConnection) ) What I'm trying to achieve now is to add this listener via the MyApplication.exe.config file Here is my configuration file: <configuration> <system.diagnostics> <trace autoflush="true" indentsize="4"> <listeners> <remove name="Default"> <add name="myDBListener" type="DBTraceListener"> Unfortunately, when im executing the application the DefaultTraceListener is removed BUT my DBTraceListener is not added!!! and I dont get any exceptions!

G. highlighting after datagrid sort in vb.net sierra_ven21-Nov-04 21:20 sierra_ven 21-Nov-04 21:20  Hi all, I just have a question regarding the datagrid's column header sort function. See, i wish to loop through the sorted table and then highlighted the required rows. So i inserted my highlighting code in the datagrid mouseup function. However, this function is done BEFORE the datagrid sorting is done, so in the end, the wrong rows end up being highlighted. Is there anyway for me to add my highlighting code AFTER the sorting of the datagrid is done? This problem has me stumped for awhile, hope help arrives soon! Thanx, Sierra Re: highlighting after datagrid sort in vb.net cwayman23-Nov-04 3:34 cwayman 23-Nov-04 3:34  Hey you could use the Private Sub DataGrid1_ItemDataBound(ByVal sender As Object, ByVal e As DataGridItemEventArgs) End Sub event as it is called for ever record in the datagrid during the databind.
