Cannot Close Excel - Process Active In Task Manager
Nov 1, 2010
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
[Code] .....
I tried to build my project but it failed and said the exe was already in use by another process. So I looked in the Task Manager and saw several instances of this exe and several instances of another exe that I wrote. Why wouldn't the processes be stopped after I close the programs I wrote. Is there something I can do so that the processes end after I close the program?
At my school people use the keyboard shortcut (CTRL+Shift+ESC) to open Task Manager. We are not allowed to use it so we get a message box saying that we do not have permission to do that. People hold down the buttons, so that a long line of hundreds of popups open. What code do i need to close all of the popups when a button is pressed?
How would I Make a program that would detect running process in the taskmanger: Info on my program +Like I want it to load the process name's in a Rich textbox or label or textbox (if that's possible XD). + And I will Have a Button that once I see all the process and then the button1 will kill the processes I Pick.
When I go to Debug my program (F5), the program will load, until I click on the form with the main part of code in it, and then the program freezes, although it doesn't lock up because as soon as I press stop debugging/ task manager end process, it closes fine.
I will attach the zip of the program here. The form that it freezes on is "Black Ops". Edit Due to the forum not accepting my .Zip file (Invalid file type), I will upload it to MediaFire. Download link (445kb): Click Here
i dont no much about vb.net ..i am php developer i have just developed a mini application in vb.net i wanted to know how to hide our application from appearing in task manager...
Need help removing a copy of my program shown on the Task Manager after I close.
I must kill a conflicting program that cannot share the COM port and then reinstate when myprogram ends. To reinstate I use: System.Diagnostics.Process.Start(conflictingPath & conflictingProgram)
In the last line of my Form1.Closed I try to end all with:System.Windows.Forms.Application.Exit()
Not working - each time I run this program it does kill the conflicting program, can do its dialing function and upon closing reinstates the conflicting program. But each time another copy shows under Task Manager.
When multithreading in VB, if you close the form while different threads are running, the process itself will not end. Is there a way I can force all threads to end, or end the process like in the Task Manager, when the form is closed?
Even though I issue the commands, the EXCEL.exe still appear in the TASK MANAGER -> PROCESS after the Excel application is quit, closed and terminated.
i got vb.net application when i debug in task menager the EXCEL.EXE is closing correctly after all operations. When i scheduled it the excel.exe is running. What can be a reason of that?Sample of code :
Imports Excel = Microsoft.Office.Interop.Excel Module Main Public objApp = New Excel.Application
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 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\ \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
how can i close a hid form without make "end process " in the task manger.how to save a textbox.text inside text file if the form closed be "end process " in the task manger?
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 am currently creating a task manager. But there is a problem : After killing the processes, it still remains in my list box (list of processes).I don't want to use a timer to clear the list and add the list of processes again because this will cause the list to blink.[code]
How do I make my app have a description in the Processes tab of the Task Manager? Changing the assembly description doesn't do it apparently. Right now the description is just it's name.
