I', working on a program where there are several projects within a solution. The solution contains a forms application, a couple of class libraries, and a public interface.I'm running into a strange problem where I can access the system.drawing.bitmap namespace from the main form and from one of the class libraries, but when I try to access it from the other class library or the interface, it tells me it is not defined. I've tried importing it, and calling it directly with no luck.

I'm taking a screenshot as a System.Drawing.Bitmap and trying to send it through a network as a byte array.If I take the original screenshot and simply save it to disk, it's about 200Kb.Instead I'm saving it to a memorystream so I can write that back to a Byte Array and it's coming out over 6Mb.
I have a VB.NET Windows Forms app with a logo image on the form as a System.Drawing.Bitmap inside a PictureBox.I used the Visual Studio Designer to add the logo .bmp image so I don't currently have any VB code doing anything with it.I'd like to make the current logo a clickable object/button so when I click on it a file browser dialog opens and I can select a new image to replace the current image.The current image is a local resource and is set in a PictureBox as a System.Drawing.Bitmap.How would I replace that System.Drawing.Bitmap with a file selected from the file browser dialog?

I have a program that creates a Treeview from information procured through an ODBC query and dumped into a dataset. I have three such queries set up via radial buttons as well as a refresh button that triggers whatever radial button is active at the time it's clicked. The purpose of this program is to allow drag-and-drop of selected nodes, ending with a post to the database that officially makes that change of assignment to the new node.
I am writing some simple utility applications in VB.NET. I am using Visual Studio 2010 Express.I'm trying to throw a FileFormatException exception in my code if a user specifies a file that has the wrong extension. Documentation indicates that this exception has been around since .NET 3.0. See
[URL]
However, Visual Studio gives me an error saying that System.IO.FileFormatException is not defined. It's not a typo, either. FileFormatException appears in the object browser in System.IO, but doesn't appear in the Intellisense drop down when I type System.IO.File.
