VB Net error - Access Denied while saving PNG to Documents folder.

Jeff Rowe 96

I am trying to save/copy a png file to the Documents folder from my Vb Net application. I can save any other type of file but an image. I can save the image to Pictures but I need to include it with other files as part of a report so I need them all in the same location. Why will it not let me put an image in the Documents folder? I can put them in there manually, I can save practically any other file there. I can save the .png as .pn_ but then it won't let me rename it. WHY????

    Public logofile As String = IO.Path.Combine(GetFolderPath(SpecialFolder.MyDocuments), "YT-Chaps\bin\logo.png")

This works

        If IO.File.Exists(logofile) = False Then
            Dim logotmp As String = logofile
            logotmp = logotmp.Substring(0, logotmp.Length - 1) & "_"
            Try
                IO.File.Copy("logo.png", logotmp, True)
            Catch ex As Exception
                MsgBox(ex.Message.ToString)
            End Try
        End If

This doesn't - "Copy Error

        If IO.File.Exists(logofile) = False Then
            Try
                IO.File.Copy("logo.png", logofile, True)
            Catch ex As Exception
                MsgBox(ex.Message.ToString)
            End Try
        End If

I have also tried to load it to a BMP and save it using bitmap.save, I get a Generic GDI+ error when I do that.

Did you try to keep the .png extension, but to change the name: logo2.png, for example.

Yes, it's not trying to overwrite and even if it was, that is what the ", true" is for.

Does it work in case of logo2.png, or the same Access Denied error is shown regardless the target name?

No, it doesn't work with any image extension, .PNG, .BMP, .JPG, there is some crazy limitation stopping me from saving an image file to the documents folder.

If I do a random test, I can save a .png to Documents folder on my OS :

        Dim logofile As String = IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "logo.png")
        Using bmp = New Bitmap(Me.Width, Me.Height)
            Me.DrawToBitmap(bmp, New Rectangle(0, 0, bmp.Width, bmp.Height))
            bmp.Save(logofile, System.Drawing.Imaging.ImageFormat.Png)
        End Using
