How To Write Content To The Already Opened EXCEL?
Sep 28, 2009
I need some code which checks if excel is open or not, if excel is not open then opens it (that code is fine)
else try to write some content/cellvalues to the already opened excel, basically I am creating windows application, which has been scheduled to run numbers of time in a day, when ever application executed, the application has something to write to the excel. one more thing is i don't want excel to save and close every time i execute the application, Its like transparent processing of EXCEL writing, a file is already opened, just write some content, and after writing it exit the application without either closing or saving the excel

I use the following code snippet
Dim exlapp As New Microsoft.Office.Interop.Excel.Application
Dim xlWorkBook_new As Microsoft.Office.Interop.Excel.Workbook
Dim strOriginal As String
strOriginal = Server.MapPath(Request.ApplicationPath & "/Attachments/") & "abc.xls"
xlWorkBook_new = exlapp.Workbooks.Open(strOriginal)
The code hangs in the last line. It works fine in the development environment. i deployed in windows server 2000 ,where I get this issue. the browser goes half way and throws the below exception after some time

I need to write one line at a time (user iterative process) to a command prompt that is already open.
I'd like to use VB or VBA. I know there is AppActivate, but then how do you write to it?
The command prompt is run by another program (that I can't touch).

I'm exporting my Dataset to an excel file, and I want to make sure I keep any file errors under control. One in particular that I'm concerned about is accessing a file that's already open. A general IOException occurs that says:
"The process cannot access the file 'C:Reports eport300.csv' because it is being used by another process."
Here is the line in which the error will occur:
Dim output As New IO.StreamWriter(path, False, UnicodeEncoding.Default)
I guess I could just throw a try catch around it, but what if an IOException happens that isnt related to this particular incident? Is there a way I can check to see if the file is already open before allowing this code to run? Especially when I'm using excel.

I have the code below:
Dim i As Integer
Dim objExcel As New Excel.Application
Dim objWorkbook As Excel.Workbook
objExcel.Workbooks.Add()
[code]....
At the end of this routine, eventhough the data was correctly saved to my Data.xlsx file, this routine also opened 15 EXCEL.EXE tasks in task manager.I thought that I had cleaned up before quitting. By the way, whether I write to 1 or 5 or 10 cells in Data.xlsx, 15 EXCEL.EXE tasks would be opened regardless.Is there a way to (easily and) completely close all EXCEL.EXE in task manager before leaving my application?

The problem I have is that I have a 3rd party add-in working in excel to convert certain info into a barcode.
When I open excel normally, the add in works without a problem, but when I open it through excel it just doesnt work until I manually go into the add-in option, disable the add-in and the reenable it.

My program opens 4 excel spreadsheets updating info. I update one at a time and then close it before opening the next one.I want to add code to my program to test if the file is already open, before trying to open it. Occasionally someone will have one of the files opened and it causes a crash. If I test to ensure it is not open, then I can avoid this.

What I wanted to do is close all opened workbooks. This code does the work IF there is at least one or more opened workbooks. My problem is IF there is NO opened workbook at all; It goes around unendlessly in the WHILE Loop. How do I not process the closing IF there is no any opened workbook at all? (NOTE: I found this code from somewhere else.)

I already know the basic procedure of how to read specific cells of an .xls file using VB.NET but I can't figure out how to automatically get all the data from such a file.Basically, I'm obtaining the data like this:
Dim xlApp As Excel.Application
Dim wb As Workbook
Dim ws As Worksheet
xlApp = New Excel.Application
[code]....
In this case, I know that there will be content in the first 10 rows of the columns A, B and C but what would I have to do if I had a huge document whose size and content might even change from time to time? I know that there is also an attribute ws.rows.count but this always returns a big value like 60000 even if only a few rows are occupied.So basically, I'm looking for a simple way to loop through all the used rows of an Excel file with the possibility of accessing each cell in that row.

I have imported a sheet from Excel. It grabs the first row as the column names saves it in a dataset, and displays it in a grid view.
here is my code to do so:
Try
'Dim MyConnection As System.Data.OleDb.OleDbConnection
Dim DtSet As System.Data.DataSet
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
[code]....
The gridview is editable, so when the user edits a cell I want to have a button so they can save the new values back to the excel sheet.
The code above cant be that dissimilar for writing from a dataset instead of reading to, but cant work it out.I want to keep the same Column headings.
