.net - Unable To Close Excel Process From App
Apr 20, 2011
I created the class below to open and gather the names of worksheets in an excel file. It does as it should in opening the file and returning the names of the each individual worksheet. Unfortunatly, I'm unable to close the file. This keeps the Excel.exe process hanging. Even after I attempt to close it at the bottom of this class the process still hangs. I have to manually goto Windows Task Manager and kill the process before I can use the file again. Even if I exit out of the application it still is out there.

I have developed a VB.Net code for retrieving data from excel file .I load this data in one form and update it back in excel after making necessary modifications in data. This complete flow works fine but most of the times I have observed that even if I close the form; the already loaded excel process does not get closed properly. I tried all possible ways to close it but could not be able to resolve the issue.
Find below code which I am using for connecting to excel and let me know if any other approach I may need to follow to resolve this issue. Note: I do not want to kill the excel process as it will kill other instances of the excel

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.

In the code below, I open excel file, when I try to enter some values into excel cells, and close it afterwards. For some reasons excel process is still active in task manager. I am releasing objects, quiting application like for other excel files in my program, but in this specific example can't do this. The code below is written in Visual Studio 2010, windows 7.
Imports Microsoft.Office.Interop
Public Class Form1
Public MainPath As String = System.IO.Directory.GetCurrentDirectory()
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

The code below checks to see if there are any spaces in the Username. The problem I have is when there is text in this field with a space in it, this procedure is run and I can not close the form.
Private Sub txtUserName_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtUserName.LostFocus
For i = 0 To txtUserName.TextLength - 1
If txtUserName.Text.Substring(i, 1) = Chr(32) Then
[code]....
What I want to happen is when the form is being closed, it ignores this procedure altogether. I could delete the text in the field first and then close the form, or I could not allow a space to be entered in this field.

The following code works fine but seems to leave instances of excel.exe running in the background. How do I go about closing out this sub properly?

' In progress

When I load my solution and compile it after first starting the IDE, everything works as expected. After changing source and recompiling, I get the following compile error:
Error 11 Unable to copy file "objDebugCAMDRS.Library.dll" to "binCAMDRS.Library.dll". The process cannot access the file 'binCAMDRS.Library.dll' because it is being used by another process. CAMDRS.Library.
After closing Visual Studio 2005 and reopening the solution I can compile again successfully. This is an old solution that has been fine for a long time. I just recently changed computers and reinstalled everything.I am running win XP Pro sp2, Visual Studio 2005 sp1.

I've been doing some research on controlling another exe without Process.Kill() .
The reason why is that I want to have a main controller program that starts and terminates my other exes . I can't use Process.Kill() it just kills my exe without giving it a chance to save data or handle the form closing event . I want to separate my program to multiple exes to prevent a scenario which is if one of the exe hangs , all the other exe hangs .
When the termination event or signal is received , then the exe would do a rollback or handle the closing part to prevent data loss etc .
So far , I've only found some methods of doing that .
1) using TxT files to communicate between exes.
2) Inter-Process Communication (IPC) using name pipes .

I have a vb application(1) which is made to launch another software(2) with specified parameters, but i wanna keep my application opened as long as the 2nd one is opened too, and I also want to close the second one automatically if mine has been force closed by the user in windows taskmanager, on the desktop, or in any way.
So I need something which detects if windows is closing the program and kill the second application auto.
I would like to avoid the task manager block, because that isn't necessary for this i guess.

I've created a very basic WF Shell project which runs an EXE (xyz.exe) in the WF Shell project's Resource folder. I can get a command line working from the Shell to open the other EXE (xyz.exe). But, I can't get code to close the Shell project's other EXE (xyz.exe) once it is opened. The xyz.exe windows called by the Shell continues to stay open even if I pass a "close" command line to the Shell.
The following code (which Paul suggested in another posting) will not close the other (xyz.exe) EXE's running process (when called by the Shell). While the Shell seems to be able to return it's called subordinate EXE's (xyz.exe) ID, not sure how to use such an ID to close its process.
Imports System.Diagnostics
Module Module1
Dim resourceFolder As String = Application.StartupPath & "Resources"

I wrote a program using VB 2008 Express Edition and noticed that when I close the program (by clicking the "X" top right corner), sometimes the program is still showing in processes within Task Manager.What do I need to include in my programming to make sure this does not occur - i.e. make sure the process ends when I exit the program?

I run a process (ffmpeg) in a backgroundworker and need it's output to calcute remaining time, estimated filesize etc. but I don't get any output from it. Here's the code used in the DoWork sub
Dim p As New Process
pback.WorkerReportsProgress = True
pback.WorkerSupportsCancellation = True
Dim tmpopts As MyOpts = DirectCast(e.Argument, MyOpts)
[code].....
The process runs and creates the file I'm expecting. I just don't get any output from it while doing it's work. The debug MsgBox shows one time and contains nothing but if I run ffmpeg without redirection in a shell it's outputting a new line every second.

When i push the close button on the top right of the exe i made, the process still runs. How can i make it to where when i close the exe it closes the process too? Also, (this is for shits and giggles) if i wanted to make a button that closed certain processes, what would the code be? For example, the button would close explorer.exe, googledesktop.exe, ect.

I've created a very simple form with one button on. I need it so when the form runs, it opens in the bottom right hand corner of the screen regardless of the resolution. It also needs to be always on top of all other applications.
When the buttons pressed, i need it to close all iexplore instances and reopen a fresh instance.
I've tried to search for the answer but to no avail.

I have a Windows Service that needs to start other processes under a user context other than that used by the service. I've seen other posts related to this but have seen no resolutionI've tried many things and have been unsuccessful in starting the process from a Windows Service when a username, password is supplied. orking as it's a requirement of our system to do this and it worked fine until recently and only fails on Vista and Windows 7 (works on XP).
The following code is used to start the process.
Dim P As New Process
P.StartInfo.Domain = Domain

I have an application that allows the user to upload information from and Excel sheet. Since the user is more familiar with Excel, they prefer to do it this way. My software will close the workbook with Me.exApp.Workbooks.Close() , but if you have the task manager running, you can see the Excel application continues. I know the workbook is closed, b/c it asks if you would like to save changes. One instance of Excel will close when the program is exited, but the user normally builds a folder of Excel files and does them all at once. If 8 instances of Excel exist, only one will close with the program.

I don't know if this is a VB2005 or MS Excel issue so I will start with VB2005.
This is how I open an Excel file in VB2005[code]...
The problem is MS Excel always open a Book1.xlsx in addition to my Data.xlsx. As such closing Data.xlsx only closes Data.xlsx but not Book1.xlsx. Over time, as I continue to develope and debug my program, Task Manager would collect "countless" Book1.xlsx. Wth EXCEL.EXE still opened, I noticed that my VB2005 doesn't work "completely" right.
If this is a VB2005 issue then how do I "completely" close everything that is Excel? If this is a Windows issue, and if you could offer a solution as well

I am trying for the first time to automate Excel 2007 using VB.Net. I have VS 2008 Pro running on a machine with Windows XP 64-bit. All updates have been applied.
Like other posters, my problem started out with Excel.exe hanging up in the task manager, even after calling the Quit method. I have tried to recreate the suggestions of using the Garbage Collector and Marshal.FinalReleaseCOMObject methods. The problem that I get now is that after about 20 seconds during which I can still see EXCEL.EXE in the task manager, I always get the Microsoft message box stating: "Microsoft Office Excel has encountered a problem and needs to close." asking me if I want to send or not send a report.[code]...
