.net - Excel Process Continues Running?

Apr 15, 2011

I'm calling the following method from a button click event to export a datatable to excel. After the export is completed, the excel application object is quit, released and assigned to nothing. But in reality it's not getting released and stays active unless the entire application is closed. So every time the button is clicked for export, a new excel application object keeps on running. How can I solve this?

The problem doesn't occur if two of the lines from the method below are not used. But I can't omit them as they are really needed. Check the * marked lines.

Using WSF (Windows Scripting File) To Retrieve Component Services Running Process ID's Using Running Process Name

May 7, 2009

I am trying to write a Windows Script that will allow me to monitor the following: That 2 x seperate but specific processes within Component Services "Running Processes" list are currently running and have not reset within the past hour. If I already know the PID, then I can retrieve the CreationDate (I assume which I can use to check for restarts? or is this the actual process creation/installation date) for each specific process, however if a restart occurs the PID will change and my script needs to know what the new PID is without me telling it!

Unable To Diligently Close The Excel Process Running In Memory

Apr 21, 2010

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

Releasing Excel COM Object Method?

Sep 23, 2011

Well, I've searched numerous threads and I'm stumped. Though my VB.net experience is newb status.I'm interacting with Excel Workbooks/worksheets with:

Imports Excel = Microsoft.Office.Interop.Excel

Now I'm fairly adept with getting data from the excel sheet with no problem.But each and every time I quit my widows form, or execute a new command_button click to repeat an operation, in the task manager, excel.exe then opens up a new instance.Releasing the the Excel COM object seems to offer a bit of head scratching.I realize that you can get your form to activate and retrieve data from whatever spreadsheet has been directed to be opened, but I can't seem to put it back and close it correctly.I have read about the Marshal. release object methods and garbage collection with no luck so far.Do I need to import another liberary that completes this operation? I would asssume this would be taken care of as apart of the:

Imports Excel = Microsoft.Office.Interop.Excel

close excel instances opened up by my windows form? Somethig like this:

Dim xlApp As Excel.Application
Dim xlWorkBook As Excel.Workbook
Dim xlWorkSheet As Excel.Worksheet

[code]....

(so that it is no longer looked at as "read only" when the spread sheet is opened up from directly from excel)As A minor work around, I've teminated it from the task Bar with proc.kill() but this does not help because my ultimate goal is to just simply realease the excel sheet when my windows form is finished getting its data.This following code does not seem to work.

releaseObject(xlApp)
releaseObject(xlWorkBook)
releaseObject(xlWorkSheet)

Excel Remains Running As A Background Process After Performing Mail Merge And Exiting?

Aug 26, 2009

I have a spreadsheet that contains details of change requests; one row per request. This information needs to be copied into a Word form for sending off to our customer who then completes the response section. To speed up this process I have written some code that utilises the mail merge feature of Word and merges the relevant info from the spreadsheet into a Word form. This runs from Excel when a button is pressed.The problem comes when I go to save the workbook and exit Excel; it stays running in the background as a process in task manager.

[URL]

I'm fairly sure it has something to do with the merge code itself but my knowledge of VB is enough to grasp what is happening but not why it is happening. If I open the Word doc that has the merge fields in it, then open the spreadsheet that houses the info Excel says the workbook is already open.

Hook Excel - The Process Excel.exe Doesn't Finish After Close Excel

Jul 20, 2010

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.

Force A .NET Dll Running In A 32 Bit Process To 'act' Like A 64 Bit Process?

Mar 2, 2011

I am almost sure this isn't possible but it's worth an ask... We have a .NET DLL that is being called from our VB6 application. The VB6 app runs in a 32 bit process so the DLL runs in the same process (it's compiled as any cpu) Therefore when I do my ODBC Database access in the DLL is will only use a 32 bit driver, as this is what it thinks it needs (for the record the DB is Pervasive PSQL)

My problem arises when the application runs on a 64 bit machine (when only the 64 bit ODBC driver is installed) as it can't find a suitable driver to use. So is there a way to force the .NET DLL to run in a 64 bit process (compiling as x64 doesn't work because register for COM Interop is not allowed) This isn't necessarily an issue at this point in time because I can install the 32 bit driver, but at some point in the future I can imagine that 32 bit driver may not be available so I will be up the proverbial creek.

If processA, ProcessB is running then END ProcessC. If however ProcessA, and ProcessB are not running then ProcessC can stay active. I have started the project and am able to kill the processes etc. This is shown below.

Checking If Certain Process Is Running

Jun 27, 2010

I need to create a program that checks to see if a certain process is running, but I need to check it at a predetermined interval, such as every 10 seconds. I also need it to relaunch the program if it disappears/crashes. I have no idea where to start, I'm assuming I'd have to use a timer and write a method that checks for this process and then another method to simply launch it.

But sometimes it already ended before I even get to this line of code, so it throws an exception that the process is not running. I don't want to catch this using a try catch, but using a if statement. How can I do this?

If Process.GetProcessByID(processID).IsRunning = true then
