error handling in vb.net

I am trying to capture errors specific to the floppy drive. I want to capture the error number for floppy not in drive, disk write protected and file not found, any help appreciated Thanks

Here is how to check if floppy is in

Imports System.IO
Public Class Form1
Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "
#End Region
Dim Retries As Short = 0

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Try
PictureBox1.Image = System.Drawing.Bitmap.FromFile("a:\fileopen.bmp")
Catch
Retries += 1
If Retries <= 2 Then
MsgBox("Please insert the disk in drive A!")
Else
MsgBox("File Load feature disabled")
Button1.Enabled = False
End If
End Try

End Sub
End Class
