plz help.

when u reply to post .. use advanced editor.

u will find attachment option there

attach the screen shot of your error there.

here is screen shot of my error,
thnx for help.
actually want to fetch data(eno,lname & fname) from emp table to payroll table payroll there i m getting error in lvName_SelectedIndexChanged function.

Dim cmdfill As New OleDbCommand("SELECT eno, lname & ', ' & fname as Name FROM EMP", Connection)

change this to

Dim cmdfill As New OleDbCommand("SELECT eno, lname + ' ' +fname as Name FROM EMP", Connection)  ' if you want space (' ') between lname and fname

or

Dim cmdfill As New OleDbCommand("SELECT eno, lname + ',' +fname as Name FROM EMP", Connection)  'if you want , between lname and fname

and i think this will solve the problem

thank u Sir for reply,
i did changes as u said bt still getting d same error,
when i run the project first this error get shown then form get display
and when i click on the item from list again error get shown(screen shot error1) on each click
and data didn't fetch from table

i have seen your project... there were so many errors in your sql queries...

first of all when you specify where and there are more than one criteria then use AND between them.. but u used , .

i have also change you access database..nothing more just

specified DefaultValue 0.00 for DailyRate,Allowance,Incentives in EMP table..
also change type of eno from number to string

and yes another thing is that you should use Parameters for passing values to sql queries.

i have used it in you GEtpayslip() method.. please see it...

ok.. paste your code

here is my crystal report code, it shows garbage values but its working on run time

Dim rpt As New CrystalReport1() 'The report you created.

        Dim ACCESS_CONNECTION_STRING As String = cnsettings()

        '  Dim myconnection As New OleDbConnection(ACCESS_CONNECTION_STRING)

        Dim mycommand As New OleDbCommand
        Dim myDA As New OleDbDataAdapter
        Dim ds As New DBDataSet3
        Try
            Dim myconnection As New OleDbConnection(ACCESS_CONNECTION_STRING)
            mycommand.Connection = myconnection
            mycommand.CommandText = "select * from payroll"
            mycommand.CommandType = CommandType.Text
            myDA.SelectCommand = mycommand
            myDA.Fill(ds, "payroll")
            rpt.SetDataSource(ds)
            CrystalReportViewer1.ReportSource = rpt

        Catch ex As Exception
