I'm trying to edit an existing xls and just overwrite it without a prompt to overwrite. I thought it was something like Excel.DisplayAlerts = False but that's erroring with 'DisplayAlerts' is not a member of excel.
So this is my current closing code that doesn't work.
oBook.SaveAs(ExcelFilename)
Excel.DisplayAlerts = False
oBook.close()
oExcel.Quit()

I currently have two applications. The main app and the updater app. When the main app checks his version with the webservice and it is out of date, it will download a zip archive and then start the updater. The updater will extract the zip archive overwriting the old files of the main app.
Is it possible to do this without the need of a 2nd app, in this case the updater? Can you like, store your application in the computers memory and overwrite the files?

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. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

I have a dataGridView and tied it to a button that saves every time you click it. and every time you click it, I want to write a line to a txtfile that displays how many records were changed and the date that they were changed. Everything works fine but every time a save has been made it over write the previous entry on the text file. Here is some of the code.
If changes > 0 Then
MessageBox.Show(changes & " changed rows were stored in the database.") ' changes shows how many entries were changed
swDate.WriteLine(changes & " record changes on " & entryDate) 'entryDate is formated as date with value of "Now"
Else

Looking at my problem I cant really justify or implement a For Each..Next or a Do While..Loop. My vb knowledge is limited so go easy on me.

I am trying to import a bunch of excel 2003 files all with A:H columns and they are under the same headings etc. into a table in access 2003 database. This is a module in access im making. Im using a file search to look for every file that begins with Format (which they all do ) to get at all the files in the folder path. is there a more efficient way to do this? somehow select all files in a folder? and import each to the same table in access? The DoCmd.TransferSpreadsheet seeems to take each file path individually so I'm not sure how to get each file name in the folder to import it.
I have this at the moment:
Sub Import()

Set db = CurrentDb
