VS 2010 Closing Excel Process List?
May 23, 2012
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.
Using this for my Imports

I'm trying to kill excel process opened by my tool.I found following working
Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Int32
Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Int32, ByVal wMsg As Int32, ByVal wParam As Int32, ByVal lParam As Int32) As Int32
[code]....
Anyway I would like to close ONLY EXCEL process opened by my tool and I don't want close other EXCEL files opened before tool.

Issue: The .xls file has about 800 records but it's only importing about 480 records. I step through each row and find out that some rows have null values.After spending some time I believe I figured out why this is happening. My first field is a SKU value. The first x rows have all numeric values. Then it gets to a SKU like '1234-SE' and this row doesn't have data. So it's like it takes on the field type of the first data type.Question: Is there a way to order the data before I populate the dataset? I tried to do an order by but didn't work.My current code that is not working as I want.**NOTE: I have tried 'ORDER BY SKU ASC' and didn't work as well.
Sub FillDataSet(ByVal sFile As String, ByVal sTab As String)
Dim containsHDR As String = "Yes" 'Change to "No" if it doesn't
Dim strConn As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='" & _

I need to access the current instance of MS Excel. To do that, I wrote the following code:
Imports Excel = Microsoft.Office.Interop.Excel
Imports System.Diagnostics
Private _ExcelApp As Excel.Application
[Code].....
The code runs nice, but it has a problem: After the user close the Excel application (click button X - note: no other instance of Excel exists), if you open the Windows's task manager, its possible to see the process Excel.exe.
If I open and close the Excel application, there is no process Excel.exe, but if I run my code with the Excel application openned, after the user close the Excel application, the process Excel.exe isn't finished.

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'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 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.

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.
[code]...
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 am extracting a column with 8760 cells from an excel file to my graph in my vb application. I managed to open and close the excell sheet from my program. However, when I try to run my application I receive this message:
There is a large amount of information on the clipboard do you want to be able to paste this into to another program later?
Is there a way that I can avoid receiving this message when calling the data from the excell file?

What I wanted to do is close all opened workbooks. This code does the work IF there is at least one or more opened workbooks. My problem is IF there is NO opened workbook at all; It goes around unendlessly in the WHILE Loop. How do I not process the closing IF there is no any opened workbook at all?

I am using visual studio to create an application that opens an excel file and then for each entry in the first column the entry in the second column is stored in an array. Then excel opens two other workbooks and for each entry in the first column it searches for a match in these other two workbooks and stores the corresponding value in an array.
Anyway, the problem is closing excel afterwards. I have used the thread: [URL] to work through the basics of cleaning up. I used the cleanup code provided and added the WithEvents caveat. I do not have strict option on.
I believe the problem is the fact that I have three workbooks open.
This is my cleanup code: (wrkbk, wrkbk2, wrkbk3 are the workbooks; datasheet, datasheet2, datasheet 3 are the worksheets; excel is the application)
Code:
GC.Collect()
GC.WaitForPendingFinalizers()
GC.Collect()
[Code]....
I got the impression that order was important in the cleanup procedure so I have tried some variations of moving the workbooks and worksheets around.

I am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")

I may be the only person still automating excel this way and I am looking at doing it in ways that better handle COM objects and such, but for now I just importMicrosoft.Office.Interop.Excel and go for it. Something that gave me a lot of grief at first was hanging excel.exe processes, but there are tons of resources online for fixing that. At this point I am pretty confident in my abilities to handle it.One thing I did notice and was wondering about is how does closing a windows forms application interact with excel.exe running in the background and likely more specifically the garbage collector. I have written quite a few excel automation projects and noticed that after I run my program .exe and it has completed there is an excel.exe process that hangs on until I close the pop up window from the windows forms application. Why is that happening?
