I am deploying the batch process on a production server and need to have the excel libraries loaded. The process runs at 6am and creates an excel spreadsheet that is ftp'd elsewhere. Anyhow - I cannot seem to find a way to load the libraries I need without loading Office on the production server which for obvious reasons we do not want to do. So how do I deploy this application?
View 1 RepliesI'm looking to add reference object libraries relating to excel and none are available to select from my directory. I have Microsoft Office Excel 2010 Express installed. Where can I retrieve this object library (and others?). Looking to import and export data to/from excel.
View 7 RepliesI'm having different results when running openfiles.exe manually than when I run it with Process.start() Below is the portion of code making the call. I have read in several places that using the "runas" verb might make a difference since I am running on Win 7 x64, however I am still experiencing different results.

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.
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?
Private Sub ReadExcel(ByVal childform As Fone_Builder_Delux.frmData, ByVal FileName As String)
' In progress
childform.sampleloaded = False

I designed 7 class libraries for 1 project.The project references all 7 libraries.3 of the 7 libraries make references to the other 4 libraries.I thought of just duplicating the code that's referenced in the other 4 libraries, but thats a lot of code.
Example:
PrjctA makes reference to LibA, LibB, LibC, & LibD.If LibA references LibB & LibC also will this fail?
i m trying to get excel sheet-name of a excel file from vb.net 3.5 however it opens but excel.exe still remains in the process. How do i stop the process without killing the excel.exe from task manager?i realise new excel.application starts new process.i tried to use quit, close and dispose.....nothing worked
Below is my code
Dim sheetName As New Excel.XlSheetType
Dim newExcell As New Excel.Application
Dim newWorkBook As Excel.Workbook = app.Workbooks.Open(MyFileName)
[code]....
I cannot use kill because there are other excel application running, so how do i close this particular excel.exe from processor.
When I create an instance of an Excel Application class and then quit the app and release the object (like below) the EXCEL process is still running in the the task manager. I have built an algorithm to find the process id and kill the process through that but I shouldn't have to.
xlApp = New Excel.ApplicationClass
'do stuff with excel app class instance
xlApp.Quit()

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 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.

There to all gurus,I'm trying to build an Excel generation aplication using VS 2008 and Microsoft Excel 2003, but some how the Excel process that i create it's stuck in the computers memory, and it's only removed when I END the VB Application.

View 4 RepliesI have written Code for Excel File Create via ASP.Net with VB Code, I want Kill the process Explictly..I already used GC.Collect(), But it takes more time.
View 4 RepliesI am currently building a vb windows form application (.net 3.5 framework). For the next part of the application I want to be able to use an existing excel process which will have been checked out from sharepoint and manipulate the worksheet with my app.
View 1 RepliesI would like to learn, to view the excel file from our vb.net. When I try to display the Excel file through the process, suppose if there is no process for excell.exe, [means not opened any excel file or excel.exe is not running in task manager] then that file can be viewable smoothly from following code.
But supoose previously any excel file is opened means, then its giving error like "Object reference Not set to an instance, use New Key word....." Also when i try to kill the process for excel.exe, it will kill the other opened excel files also.

I'm using VB to create Excel templates and everything appeared to be working fine until I was stepping though some code today with my Task Manager open. I noticed that I had numerous instances of Excel open that should not be. This is the code that is being called to close the process:

When stepping through this code I am hitting the exception after the execution of the GC but the message box does not appear so the the using thinks that everything is fine. When I close my applicataion all of the Excel processes shown by the Task Manager close as well.
I'm trying to kill excel process opened by my tool.I found following working

I'm trying to create an excel file and load headers into the first row and then save the file to the local computer for later use. All of that works fine, but for some reason the "EXCEL" process won't quit. I have read through the tutorial written by Mike R and I have even tried just copying and pasting the code from the tutorial into my project, but to no avail. I should also note that I have not yet tried the "Extreme Measures" listed in the post, though at this point I am tempted to.
Code:
Dim ExcelApp As Excel.Application
Dim ExcelWorkBook As Excel.Workbook

I got exactly the same situation as the following link. I need to end the excel process after calling it in Visual Basic. But it did not and I have to use task manager to kill EXCEL process manually.

I'm developing app in VB.NET 2008.
I have one prob that i'm creating excel sheet runtime, loading data and printing excel sheet through my application. Actually it has 150 sheets to print.
i'm printing by using this code
xla.Sheets.PrintOut(Copies:=1, Collate:=True)
To print 150 sheets , its taking around 17 min. so now the user is waiting until printing process finish(ie 17 min ) .
actually i don't want to make him wait, i want to execute this printing process in backgroud. so the user can work on other process in my app.
how to print this in background ?
Im opening an excel document with vb.net and i dont want vb.net to close it but to release excel so that when the user closes excel it does not remain as a running process... which it currently is doing here is the code i was using
[Code]....
Okay so my program opens excel, reads a few cells, and closes excel. But, it does not fully close excel and after multiple runs, I have multiple EXCEL.EXE *32 in my process list. It also asks for a save when it's closing when there are no changes being made, is there any way to avoid this? And how do you get Excel to fully close?
[code...]
The program closes, without asking for a save, gets me the data I need, but remains in the process list.
Using this for my Imports

This is simple to explain, i need to track the process id from the files I execute. So lets look at the code.For this example just create 2 files in the C: and call it 1.xlsx and 2.xlsxNow open the firts file ...
Dim objFileExecute As New System.Diagnostics.Process
objFileExecute = Process.Start("C:1.xlsx")
MsgBox(objFileExecute.Id)

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 need to open a .xlt for editing, like so:
System.Diagnostics.Process.Start("Template.xlt", "Editable=True")
But I don't know the correct switch in Excel. This is the same as right-clicking on an .xlt and choosing "Open", whereas the default action is "New".
I want to upload a large file of tracking numbers and process them into our ordering system.
I used to use Server.ScriptTimeout = 3000
It worked until we upgraded our servers and now it crashes.
I'm Getting This webpage is not available The connection to www.YourSite.com was interrupted.
I could see the .csv file has been uploaded, but many tracking numbers do not get processed.
I'm thinking of maybe switching to a asynchronous update. But I cannot find any good source for it.
If you have any good ideas, please let me know.
Issue: The .xls file has about 800 records but it's only importing about 480 records. I step through each row and find out that some rows have null values.After spending some time I believe I figured out why this is happening. My first field is a SKU value. The first x rows have all numeric values. Then it gets to a SKU like '1234-SE' and this row doesn't have data. So it's like it takes on the field type of the first data type.Question: Is there a way to order the data before I populate the dataset? I tried to do an order by but didn't work.My current code that is not working as I want.**NOTE: I have tried 'ORDER BY SKU ASC' and didn't work as well.
Sub FillDataSet(ByVal sFile As String, ByVal sTab As String)
Dim containsHDR As String = "Yes" 'Change to "No" if it doesn't
Dim strConn As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='" & _

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 have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).
