อันนี้โค้ต ComboBox Code (VB.NET)
Private Function ComboBoxCnn()
con.ConnectionString = cnnStr
Dim sql As String = "SELECT * FROM Product"
Try
con.Open()
cmd.Connection = con
cmd.CommandText = sql
Dim dt As New DataTable
With ComboBox1
da.SelectCommand = cmd
da.Fill(dt)
.DataSource = dt
.DisplayMember = Pro_ID
.ValueMember = Pro_ID
End With
Catch ex As Exception
MsgBox(ex.Message)
End Try
con.Close()
Return tmp
End Function
ลองแบบนี้แล้วแต่ยังไม่ได้ค่ะ

Dim a as string = "a0002"
