What the ****, memorystream question.

Here is my code, the Pos1 - Pos6 objects are Pictureboxes. They all contain pictures that I want to send to a dataset, before I can do that I have to save them to memorystream variables...

When I run this code I get the following error...

An unhandled exception of type 'System.ArgumentNullException' occurred in system.drawing.dll

Additional information: Value cannot be null.

I don't know what to do because the value of the pictureboxes is definately not null. I can verfiy that through the command window in debug mode. It tells me that it is a valid bitmap object. Any advice would be much appreciated.

Code:

---

        Dim Image1 As IO.MemoryStream
        Dim Image2 As IO.MemoryStream
        Dim Image3 As IO.MemoryStream
        Dim Image4 As IO.MemoryStream
        Dim Image5 As IO.MemoryStream
        Dim Image6 As IO.MemoryStream

        Pos1.Image.Save(Image1, System.Drawing.Imaging.ImageFormat.Bmp)
        Pos2.Image.Save(Image2, System.Drawing.Imaging.ImageFormat.Bmp)
        Pos3.Image.Save(Image3, System.Drawing.Imaging.ImageFormat.Bmp)
        Pos4.Image.Save(Image4, System.Drawing.Imaging.ImageFormat.Bmp)
        Pos5.Image.Save(Image5, System.Drawing.Imaging.ImageFormat.Bmp)
        Pos6.Image.Save(Image6, System.Drawing.Imaging.ImageFormat.Bmp)

Hmm. Not sure, but I think you need to change you Dim statement.

Try Dim ImageX As NEW IO.MemoryStream

Well, that was embarassing. One of those days when you have been working too long to catch the obvious. Thanks for the second set of eyes.

Is there still an issue with late binding like that in VB.net?

VB6 used to be slower with late binding.

dim x as thingy = new thingy 'early binding good :)
dim x as new thingy 'late binding bad :(
