Access to file used in picturebox

Beautiful Scott! 

I actually was going down that road initially, as the dll that generated the temp file had a function that wrote to file stream, but it had compatability problems with VB filenumber, it required a filehandle. 

Thanks very much. 

Open it from a memory stream rather than from the file; once you dispose of the memory stream and can delete the source file at will (here is an example with a form, picturebox, and a button, the image is loaded at form load, the button click event deletes the file after setting the picturebox image to nothing (which is not required, you can leave the image showing and still delete the image file):

Imports System.IO

 

Public Class Form1

 

 

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

 

        Try

 

            Dim fsImage As System.IO.FileStream = Nothing

            fsImage = System.IO.File.Open("c:/Temp/junk.bmp", FileMode.Open, FileAccess.Read)

            Dim bArrImage(fsImage.Length) As Byte

            fsImage.Read(bArrImage, 0, Convert.ToInt32(fsImage.Length))

            fsImage.Close()

 

            Dim ms As New MemoryStream(bArrImage)

            PictureBox1.Image = Image.FromStream(ms)

            ms.Dispose()

 

        Catch ex As IOException

 

            MessageBox.Show(ex.Message, "Error Opening Image")

 

        Catch ex As Exception

 

            MessageBox.Show(ex.Message, "Error Opening Image")

 

        End Try

 

    End Sub

 

 

    ' clear the picturebox and delete the source image

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

 

        Try

            ' you don't have to clear the image first but if you

            'want to, just set the image to nothing

            PictureBox1.Image = Nothing

 

            ' delete the source file used to

            ' populate the picture box image

            System.IO.File.Delete("c:/Temp/junk.bmp")

 

            ' disable the button after the image

            ' is gone

            Button1.Enabled = False

 

        Catch ex As IOException

 

            MessageBox.Show(ex.Message, "Error Disposing of Image")

 

        Catch ex As Exception

 

            MessageBox.Show(ex.Message, "Error Disposing of Image")

 

        End Try

 

    End Sub

 

End Class
