I'm fairly new to VB, but I have some C, C++ background.
I'm trying to open an existing Excel Document, and add data in specific ranges from Text box inputs in my VB program. However I cannot seem to be able to do this.
The closest I've gotten was to Open the document, and save data, but it erases the items that were already in that document.
Can anyone help me out with this?
Here's what I have so far, haven't incorporated getting the data from the Text boxes yet - as I wanted to ensure the saved document would have the added information, along with the pre-existing data.
Dim oExcel As Excel.Application = New Excel.Application
Dim oBook As Object
Dim oSheet As Object
oBook = oExcel.Workbooks.Add
'Add data to cells of the first worksheet in the new workbook.
oSheet = oBook.Worksheets(1)
oSheet.Range("A1").Value = "Last Name"
oSheet.Range("B1").Value = "First Name"
oSheet.Range("A1:B1").Font.Bold = True
oSheet.Range("A2").Value = "Doe"
oSheet.Range("B2").Value = "John"
'Save the Workbook and quit Excel.
oSheet = Nothing
oBook = Nothing
oExcel = Nothing
Thank you for any help you can provide!
(it wouldn't surprise me if the above is completely wrong..)
