How to get a picture into a byte array

[Rasmus Teglgaard]

Hi

I'm trying to get a picture uploaded to the picture attribute in Active Directory. I've got most of it working, the only thing I need now, is to convert this picture to a byte array, so that I can save it in the AD

Does anyone know how to do this

Thank you VERY much in advance

Re: How to get a picture into a byte array

Hi Rasmus,

Try this

Dim ms As New MemoryStream
Dim arrImage() As Byte
originalImage.S ave(ms, ImageFormat.Jpe g)
arrImage = ms.GetBuffer

I thought ImageFormat.Bmp is better but I needed this for something extra

I hope this helps,

Cor

I am not familiar with AD, but that do you want to say with "uploaded to
the picture attribute"? In what format does the picture get uploaded?

Re: How to get a picture into a byte array

Hi Cor

Your my man! It worked - apparently

The reason for the "apparently " is that, I get no errors (which is usually a good thing :0)
The thing is, that I am not able see if this worked, before I can get the binary data back from the active directory and convert them back to an image and display it

So, I was wondering if you (or others) could help me with this - to get the binary data back and convert them back to the picture again

I can't express how much help you've been, thanks again

It should be uploaded in a byte array (binary).

Re: How to get a picture into a byte array

Hi Herfried,

Thank you very much for your apply.
I've already gotten a solution from Cor though, and I've tried that, and it appears to be working. In this case, I'm using a memorystream rather than the filestream.

I've got one last question though.
I've now managed to get the picture into the active directory (I think). Now I need to get it back. So now it's the other way around.

How do I make a byte array to a memorystream, that I can then import to a picturebox in VB?

Thanks in advance,
Rasmus

\\ Dim fs As FileStream = New FileStream( _

Dim br As BinaryReader = New BinaryReader(fs )
Dim abyt() As Byte = br.ReadBytes(fs .Length)

Keep the 'MemoryStream' alive as long as you use the image.
