I have a global variable that is of type Image. I set this to different
images in different routins using BitBlt to copy from the screen. If I
dispose of the variable image after I'm thru with each image, not only the
image is disposed but also the variable and I can't reference it again.
Question is do I need to dispose of the old image...

I don't think I clearly stated my problem in my prior question so let me try
again. I have the following:
Private myobject as Bitmap
myobject = mybitmap (created from a part of the screen)
How do I dispose of the instance of mybitmap object yet retain myobject so I
can use it again like:

I'm using TCP/IP to send a Bitmap object over Sockets. This is my first
time using C# at all so I don't know if this is the "right" way to do
it. I've already found out several times the way I was doing something
was really inefficient and could reduce 10 lines of code with 2, etc.

Suppose I have
Dim bm As New Bitmap(16, 16,Imaging.PixelFormat.Format8bppIndexed)
I cannot use
Dim g As Graphics = Graphics.FromImage(bmdest)
Dim hdc As IntPtr = g.GetHdc()
as the FromImage call will fail for indexed bitmaps.

I'm rather confused as to whether something should be disposed of, or not.
