Excel Report in VB.NET

[krallabandi]

Hi,

I am trying to generate Excel sheet using
Provider=Microsoft.Jet.OLEDB.4.0;

I am always getting the error while inserting data into any cell other
than A.

An unhandled exception of type 'System.Data.OleDb.OleDbException'
occurred in system.data.dll

I am greatful to you if anyone could correct this. Also appreciate if
you can give me info about this kind of excel report generation in
VB.NET.

My OS id windows XP pro, using Excel 2000.

Here is my code:
I am using c:\temp\show.xml which is blank excel file with excel sheet
name iPOS. And also created a folder c:\temp\iPOSReports

Pls help to resolve this issue.

Imports System.IO

Now.Hour & Now.Minute & Now.Second & ".xls"
desPath = "c:\temp\iPOSReports\" & des
fso.Copy("c:\temp\show.xls", desPath)
fso = Nothing
Dim cnt As Integer
For cnt = 0 To 10
sqlStr = "Insert Into [iPOS$A" & cnt & ":A" & cnt & "]
Values ('Kiran here');"
