Query Access Database and Display Data on New Form

[rhonda2010]

I have a program in which I want to have the user enter two percentages and display the data matching the criteria on a new form. The query would be:

Select *
From Corrosion
Where corrpct1 >= {column in database} OR
      corrpct2 >= {column in database}
 

The way I currently have it written is to display only one row of data. I need to display any number of rows that meet this criteria. My current code is:

Private Sub btnDetails_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDetails.Click
        Dim form As New frmDetails()
        Me.Hide()
        form.Show()
        Try
            cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\Corrosion.mdb;")
 
            cn.Open()
            cmd = New OleDbCommand("select * from Corrosion", cn)
            dr = cmd.ExecuteReader
            While dr.Read()
                form.txtID.Text = dr(0)
                form.txtCountry.Text = dr(1)
                form.txtCompany.Text = dr(2)
                form.txtAsset.Text = dr(3)
                form.txtBlock.Text = dr(4)
                form.txtFacility.Text = dr(5)
                form.txtAreaItem.Text = dr(6)
                form.txtCode.Text = dr(7)
            End While
        Catch
        End Try
        dr.Close()
        cn.Close()
    End Sub
 

This will open the new form and put the information in the textboxes I have. However, I never know how many textboxes I will need to display.

My questions are:

1. How can I do my query to incorporate the user entered criteria (in the where statement)?
2. How can I display ALL of the data instead of just one line?

Thank you for any help you can give.

#1. your sql query will be like....
Select * From Corrosion Where {column in database} <=corrpct1 OR {column in database}<=corr pct2

#2. If this query returns more than one row then instead of using datareader use dataset....

fill the dataset(say ds) with this sql query

take a datagridview or listview or datalist in the frmDetails form

now put........
Dim form As New frmDetails()
Me.Hide()
form.DataGridvi ew1.DataSource= ds
form.Show()
