How To Shutdown Process After Closing Document
Aug 6, 2009
I'm using CreateObject(progId) in Vb to create a pdfDOcument. But the problem is that after I'm done and closing the document and release, How can I shutdown the process? How can I reference the process and know if it was already open by the user before I Created the object? And how can I kill the process if the process was not running before I created the object (pdfDocument)? Is there better strategies than to use CreateObject()?

I'm getting really really frustrated with Word's Document Recovery Pane everytime I launch Word - it is making me very mad! I'm busy with a program which assists me with all my exams, right, now, with this program I'm launching each program associated with each exam. After the document / spreadsheet etc. is shown, I mark what I need to, then, I have a button which closes the current process, and returns me to my default application interface.

I'm busy with a program which assists me with all my exams, right, now, with this program I'm launching each program associated with each exam. After the document / spreadsheet etc. is shown, I mark what I need to, then, I have a button which closes the current process, and returns me to my default application interface. All this is working, except for the .doc files, Word files.
Everytime I launch word, I get the Document recovery pane.
I've tried the following: [Code]
As a last resort ( and this doesn't work ), because WordDocument.close does not work, Word Application. Quit does not work! By, saying it doesn't work, means it closes everything, yes, but the Document Recovery PAne always shows up, and I can't understand why! Is there some way of disabling it completely
I know some will say it is not a good idea, I know, I know I really need to get rid of it.

I am working on a .NET console app which needs to clean up resources on exit. The problem I'm running into is that I don't get any notification if the cmd parent is closed via the console window [X], via Task Manager/Process Explorer or programmatically with WM_CLOSE. I can live with not being able to handle Kill Process from Task Mgr. or ProcExp. WM_CLOSE of the parent console is the most likely way that this application will be closed before it's finished processing.
Here are the events I've tried to register for so far:
AppDomain.CurrentDomain.ProcessExit += CurrentDomainProcessExit;
AppDomain.CurrentDomain.UnhandledException += CurrentDomainUnhandledException;
Console.CancelKeyPress += ConsoleCancelKeyPress;
Application.ApplicationExit += ApplicationApplicationExit;
[Code] .....
These events fire properly when I send a CTRL+C from the console or the application finishes uninterrupted. But none of them fire when the parent app (cmd console) is closed. (The parent/grandparent processes aren't CLR so I'm not sure I would ever receive those Disposed/Exited events. Those are just shots in the dark.) I've looked at some pInvoke stuff but I would rather not go down that road if .NET is an option. Is there a way to detect and handle a shutdown in these situations? I am open to any .NET, pInvoke/Win32/C/C++ solution. (Basically any way it can be done on the Windows platform.). I'm still working with .NET 2.0 so I can't use anything introduced in .NET 3.0+

I am writing an application that needs to be running all the time and I don't want the user to be able to close it. I don't want to hide the process from Task Manager. All I need is that when the user tries to terminate the process, he has to enter a password.

I am working on a program and for some reason when I run it as an executable outside of debug mode, if I run the main subroutine of the program, the process remains in memory after being closed. Even though the form is closed/gone, it will be in the process list and I have to ctl-alt-del to remove it. If I exit right after opening the form without doing anything, it closes like normal. I am closing and disposing everything I can think of, and I've never had this problem before. This is how I am exiting, but the problem also occurs if the user "X's" out.
Me.Close()
Application.Exit()
I have a couple web file requests in my program, which is the only thing out of the ordinary (code-wise) for me, don't know if those are the root of the problem. I can't imagine this is the first time this has happened to anyone, but I couldn't find anything helpful with my search terms. Any ideas/common solutions? I can post sections of my code if it will help, but the whole thing is pretty long and I couldn't narrow down any potential problem areas.

Okay so my program opens excel, reads a few cells, and closes excel. But, it does not fully close excel and after multiple runs, I have multiple EXCEL.EXE *32 in my process list. It also asks for a save when it's closing when there are no changes being made, is there any way to avoid this? And how do you get Excel to fully close?
[code...]
The program closes, without asking for a save, gets me the data I need, but remains in the process list.

I have an MDI form as the app start object.I don't think is related, but in the Form closing event, I check for some condition, and if it's true, I ask for confirmation before closing:
Private Sub FormBackground_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
If (e.CloseReason = CloseReason.UserClosing) Then[code].....
So long, everything works fine in my development machine, which runs windows XP.However, when deploying the application in a windows 7 machine, the message box works correctly, showing itself whenever it should, but after the form is closed the application keeps running in the background. This happens whether the form closes directly or asks the user first.I have fixed it putting an End instruction in the FormBackground.FormClosed event, but it doesn't feel good.

I'm developing Applications in VB.NET 2008.
I have MDI Parent Form and i'm going load all form as MDI child. Here i'm going to give option to "Close All" toolstripbutton in top of MDI Parent to close All mdi child forms.
Now i would like to check that On click of Close All Toolstripbutton , i have to close all mdi child form but except those form is on process, example, I have opened/Loaded 5 MDI child forms within MDI Parent Form.
Child forms are ( just for example ) ,
1. Customer details Form
2. Item Details Form
3. Import Orders Form
4. Stock Details Form
5. Production Entry Form
Here 3.Import Orders form is importing from Excel with 5000 records and 4. Stock details form exporting to excel.
So now if i click "Close All" button then i have close only Idle form i.e 1,2 and 5 but i should not close 3 and 4 since its on some process.
So Is there any .NET option to check that form in process/idle or do I have to check manually by having any Flags ?

Am trying to achieve a couple of things: merge a bunch of individual text files into a combined file, move the files that were combined into a new folder. I have assigned each of these tasks to a method. Something in the first method is hanging on to the file, even though I am closing and disposing the stream reader - but I can't figure out what. I know that a process from the first method is hanging on to the file because when I comment out the first method, the second method moves the files without a problem.
EDIT The first method is returning a value for new big file. This is passed as a parameter to the second method. When the second method tries to reference this file, that is when the program throws the error (5th line from bottom) Most posts on SO advise closing/disposing IO objects, but I am already doing that. They also advise using a third party tool to investigate what process is hanging on to a file, but I already know that it is the first merge method (because when it is commented out the program runs).

I'm reading a file and then closing it with the following code, but my problem is later when I start a batch process it says the file is still in use. Am I doing something wrong in closing it? The process was working fine prior to my adding this code to read the file.

This rexx exec is trying to write to the file that I read from in the prior step before creating a PowerPoint presentation, but fails becuase of the lock.I'm at a loss. I should qualify and say the process actually starts, but fails in the rexxexec after it starts, it isn't failing on the process start the rexx exec issues a message that it can't write to the file becuase it is in use.

I'm having a problem with closing Acrobat. I'm using vb.net to sign a PDF file in running Acrobat. After I'm done I close Acrobat and try to delete the currently signed PDF file, but I get an error message telling me that file is being used by another process. I tried closing and setting to Nothing AcroApp, AcroAVDoc, AcroPDDoc JSO, but still that doesn't work. I tried releasing them with Marshal.ReleaseComObject(...) still no effect.[code]

Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?

Dim frm As Form
For Each frm In Forms
Set frm = Nothing
Next frm
The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?

I have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).

I've written a program which I propose to give a local club, which sadly may be'attractive' to pirates so I propose to build in some sort of anti-copying feature.My idea is to hide a file in a folder somewhere in the club's laptop, then on program start up I'll check to see if that file exists and if it's not there, which it's unlikely to be on a pirates machine, I'll flag up a message box saying that if they have a legitimate reason to install the program on a different machine they'll have to contact myself.By way of nuisance value, pressing the 'OK' button on the message box will cause the machine running, what I'm assuming is a pirated copy, to shut down.I've been looking at the VB.NET forum and MSDN for ideas as to how to achieve this and the general opinion seems to be:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Process.Start("shutdown", "-s")
