  I have a png image in a byte array variable called sigFileImage.

  Me.ImageBox.ImageData = New IO.MemoryStream(sigFileImage)

  When I assign the stream of this byte array to the image control I get an error:
  
  Unknown type of image:137

  But it is not unknown because I can use this same stream elsewhere and the PNG shows fine.

  Hello,

  Could you share the exact version of ar that you are using? Because at my end,
  
  ImageData is “String” type property. Hence, it gives compile time error “Value of type ‘MemoryStream’ cannot be converted to ‘String’”. Also, it is very helpful for us, if you could share the project with us, so that we can replicate at our end.

  Thanks,

  Using ActiveReports v12. As you can see from the included screenshot, when I hover over the ImageData property it shows its type as IO.Stream which is just what I need.

  I included the report too although it won’t work by itself since it has many other dependencies in a very large project. But at least you can see that ImageData is indeed a stream.

  Hello,

  Sorry for delay response as I am on leave.

  Please use the following code to load the image in report:-

  
  	Dim data As Byte() = CType(objReader("SigFileImage"), Byte())
          Dim stream As MemoryStream = New MemoryStream(data)
          Me.Signature.Image = Image.FromStream(stream)
  
  

  Hope it helps.

  Thanks,
  
  Mohit
