Can't Get Automated Excel To Close Gracefully
Mar 3, 2010
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]...

I'm trying to automate writing some data to an Excel spreadsheet (Office 2010, VS 2010), save the spreadsheet, and then open the spreadsheet for the user to view and edit. When I save the spreadsheet, an instance Excel is left running in the Task manager. No matter how many spreadsheets I create, there is always instance in Task Manager left.[code]...

I have both Excel 2003 and Excel 2007 installed on my system. When I call oExcel = CreateObject("Excel.Application"), Excel 2003 is used in the context in my .NET code instead of Excel 2007 (which I need to be used). I have referenced the "Microsoft Excel 12.0 Object Library" but when the code runs, the 11.0 version is used.
Is it because I am using Visual Studio .Net 2003 that Excel 2007 cannot be correctly referenced or do I need to change a reference or setting?

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 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 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 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 have searched all the code here I can find. I have added a bunch of code that some said should fix the problem. but it persists.
Given the code below, I open a small .xml file and then try to save it as a .XLS file. Should work just fine. When I monitor Task manager, the instance of Excel shows up immediately. But despite all the code I have added, it still won't go away, even if I exit the application. And if I run the process twice, I get multiple copies of Excel in task manager.
If the instance of Excel in the task manager went away when I exited my app, I would assume that there was some reference that was instantiated (behind the scene maybe) that persists until then. But this is not the case.[code]...

I have a little program that I wrote to translate an Excel spreadsheet into a text file and pass it to another application. We found out Friday that if you give it a spreadsheet ina bad format, theprogram just hangs up: no errors and no more processing.It hangs and never finishes processing. If the format is correct, no problems.I wanted to add error logic to catch this condition.So after the try to open the spreadsheet, the first thing I do is check this one cell and if it is not right, it creates and error message, sets an indicator for the error,and closes the workbook.It hangs up on the close of the workbook.A spreadsheet with the expected format closes just fine. I even copied the close statement up to follow the detection of the error, but it hangs just like it did at a different point in the program.
I have been trying to copy the code here, but the question ends up either blank or doesn't get posted at all.The workbook is defined by oWB=oXL.Workbooks.Open("Excel.Application"). oWB.Close() is what hangs. That same code does not hang if the format is correct. How can the contents of the file affect the closing of it?

Here is the problem: I have written an application that opens an excel file, copys a chart to the clipboard, then closes the excel file. It works fine except under a very special condition. If the user has an excel file open and then runs my application, the open excel file closes. To make this more confusing, if the user then reopens an excel file and runs my application again, everything works fine. It will continue to work fine untill the user reboots his or her computer. Then it will occur again one time
Here is the section of code I found the problem is in:
Private Sub Get_R1C1_Image() 'Gets excel data to display
Dim objXLS As Object = CreateObject("Excel.Application")

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

This runs correctly, but Excel remains active after close.
If I don't create the range objects below, everything seems to work (with no output of course). Does anyone have any idea on how to keep Excel from staying in memory. Also... in the tests I'm running, I do not make the application visible.[code]...

I have VB.net code (2005) that updates an Excel (2003) file but on close I get a pop up from Excel when my code is trying to close it. How can I close and save changes and not get the pop up? ("Save Changes Made").
I tried this:
vb
xlWorkBook.SaveAs(Filename:=excelFileName2, FileFormat:=Excel.XlFileFormat.xlExcel3)
But it renamed the "Sheet1" tab and I got more pop ups from Excel.

I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.

I cannot get Excel 2010 to close by using VB on my Windows XP computer at work. I have what I thought would be able to close it, but it doesn't. I do not get any errors, it its just that after multiple times of the code running, I have multiple instances of EXCEL.EXE running in the task manager, which causes problems. I am going to post the code below:
Option Strict Off
Imports Excel = Microsoft.Office.Interop.Excel
Public Class CompareDataExcel\

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
