Consider the following code below. This code stores the filename the user returns inthe public variable Fname. If the file is already open, then the sub will not open the

file again and if the user cancels the filename procedure then the sub exits

Code:

Public Fname

Sub OpenF()

Dim wb As Workbook

Fname = Application.GetOpenFilename("Excel-files,*.xls", , "Please

open your file")

'no file selected

If Fname = False Then Exit Sub

For Each wb In Application.Workbooks

If wb.Path & "\" & wb.Name = Fname Then

MsgBox "File " & wb.Name & " is already open"

Exit Sub

End If

Next

Workbooks.Open (Fname)

End Sub

The code is totally self explanatory, In the load event we're going to open the new instance of the excellibrary and our excel file book1.xls will be accessible from our code. Then we'll use Command1 to retrievedata from book1, please note that you must have some data in the excel file. Similarly Command2 is used toput/replace the data in the excel sheet cells.

'do declare these vari ables you need to add a refe rence

'to the microsoft excel 'xx' object l ib rary.

'you need two text boxes and two command buttons

'on the form, an excel fi le in c: \book1.xls

Dim xl As New Excel.Appli cat ion

Dim xlsheet As Excel .Worksheet

Dim xlwbook As Excel .Workbook

Pr ivate Sub Command1_Click ( )

'the benif i t of placing numbers in (row, col) is that you

'can loop through different directions if required. I could

'have used column names l ik e "A1" 'et c .

Text1.Text = xlsheet.Cel l s (2 , 1) ' row 2 col 1

Text2.Text = xlsheet.Cell s( 2, 2) ' row 2 col 2
