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

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 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

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.

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 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!

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.

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.

Trying to create a button that when clicked will check to see if a certain process image is running and if that process is running give the process focus. If the process is not running then start the application.

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.

I am working on a project for a friend. It loads all php files in a specified folder and looks for text in them and if it finds a text it replaces it, then it saves the file and moves on to the next.
so it is like
txt = txt.Replace("j", "from")
there are around 13,000 lines like this that it searches the files with, it always runs out of memory at the same line. I need a way to cut down on the memory usage, it is already running on a background worker, but didnt seem to help any.

With my new client which is linked with an IP Board forum. Once they log into the client the people who donated or bought VIP on my forums will have access to all my applications I have made. It will most likely show a list of all my applications in a listbox/listview. I currently do not have the code to be able to do this nor do I know how to do this at all. I basically need to download a program into memory and run it from memory so my application will never touch the users hard drive. I would also need this connection to be encrypted by either packet encryption or SSL. If packet encryption is possible I would like to know as I can't find any examples of it in VB.net

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.

I need to create a way to dump the memory of a process to a file. And I don't mean a crash dump, I mean dumping the memory. In C++ you can use the function MiniDumpWriteDump.
Here is my code so far:
Public Declare Function MiniDumpWriteDump Lib "dbghelp.dll" (ByVal hProcess _
As IntPtr, ByVal ProcessId As Int32, ByVal hFile As IntPtr, ByVal DumpType _
As mydumptypes, ByVal ExceptionParam As IntPtr, ByVal UserStreamParam As _
IntPtr, ByVal CallackParam As IntPtr) As Boolean
Enum mydumptypes
[Code] .....
A file is created, however when I looked inside the file with a hex editor, it was complete garbage. For a test, I opened notepad, typed in "Hello!", and dumped the notepad process. I could not find any strings in it, let alone the "Hello!" string.
mydumptypes.normal =
MiniDumpWithDataSegs= 0x00000001,
in c++. It wasn't what I wanted. Anyways, I fixed it.
