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.
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 am a beginner using 2008 Express and I am trying to get my application to remember and restore some combobox values. It seems to work fine if the application is opened and closed normally but for some reason it loses the settings if it is opened from the startup folder.

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

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?
In my VbNET2008 window application I include a EXCEL Spreadsheet and it generate 2 error messages when I declared the WorkBook and Worksheet.
Here are the error message:
Error 3 Type 'objExcel.Workbook' is not defined.
Error 4 Type 'objExcel.Worksheet' is not defined.
Here are the coding that generated the error messages:Imports Microsoft.Office.Interop.Excel
Dim objExcel As Microsoft.Office.Interop.Excel.Application = CType(CreateObject("Excel.application"),Microsoft.Office.Interop.Excel.Application)
Dim objWorkBook As objExcel.Workbook = CType(objExcel.Workbooks.Add, objExcel.Workbook)
Dim objWorksheet As objExcel.Worksheet = CType(objExcel.Worksheets(1), objExcel.Worksheet)
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'm a VBA programmer and can do Office integration in Office applications.I'm programming in VB in VSTS 2008 and following these steps to create an Excell application at runtime: [URL] but it is not working.The issue I'm having is when I add the reference, the library is not recognized by VBE intellisense and compiler, so: the code doesn't run.When I use late binding technique and declare variables as objects, the code runs OK, but I don't want that way.I tried adding the references in two different ways:
1 - Menu Project / Add Reference / tab COM / Microsoft Excel 11.0 Object Library / OK
2 - Menu Project / VB Properties / References / Add / Microsoft Excel 11.0 Object Library
Both methods didn't work.
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'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file.
