Code:
    Private Sub SaveResized_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveResized.Click

        Dim bm As New Bitmap(PictureBox1.Image)
        Dim myX As Integer

        Dim myY As Integer

        myX = Val(txtX.Text)

        myY = Val(txtY.Text)

        If Val(txtY.Text) = 0 Or Val(txtX.Text) = 0 Then Exit Sub Else 

        Dim thumb As New Bitmap(myX, myY)

        Dim g As Graphics = Graphics.FromImage(thumb)

        g.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic

        g.DrawImage(bm, New Rectangle(0, 0, myX, myY), New Rectangle(0, 0, bm.Width,
        bm.Height), GraphicsUnit.Pixel)

        g.Dispose()

        Dim message, title, defaultValue As String

        Dim myValue As String

        message = "Enter File Name:" ' Set prompt.

        title = "Save Resized Photo" ' Set title.

        defaultValue = "" ' Set default value.

        'get name to save resized image, using Inputbox

        myValue = InputBox(message, title, defaultValue)

        If myValue = "" Then bm.Dispose() : thumb.Dispose() : Exit Sub Else 

        thumb.Save("C:\" + myValue + ".jpg",
        System.Drawing.Imaging.ImageFormat.Jpeg)

        bm.Dispose()

        thumb.Dispose()

        Dim caption As String = "Save Resized Photo"

        MessageBox.Show("The Resized Photo has been saved as: " & myValue, caption,
        MessageBoxButtons.OK, MessageBoxIcon.Exclamation)

    End Sub

I am using this code to resize my image in Picturebox1 to the dimensions I set in txtX.text and txtY.text .....

However I get a generic GDI+ error code when I hit

Code:
        thumb.Save("C:\" + myValue + ".jpg",
        System.Drawing.Imaging.ImageFormat.Jpeg)
Do you know if i am doing something wrong??

Thanks in advance!
