[RESOLVED] Question about Using PenSoandSo ... End Using

[EntityX]

I have a large application that has numerous places where I define pens using code like this :

 MyPen = New Pen(Color.FromArgb(Red , Green, Blue), ws)

If I define the pens in one place and then afterward use :

 
  Using MyPen 
     Graphics.FromImage(bmp).DrawLine(MyPen, p1, p2)
  End Using

is that ok or should I instead define the pen right where I have Using like this :

  Using MyPen = New Pen(Color.FromArgb(Red , Green, Blue), ws)
     Graphics.FromImage(bmp).DrawLine(MyPen, p1, p2)
  End Using

If it doesn't make any difference then I can save myself an enormous amount of work but if there is a very good reason to do it like the code immediately above shows then I can make the conversion. My application is working just fine the way it is now and I'm not using "Using ... End Using" at all but I'm guessing that my application may be using up more system resources if I'm not using "Using ... End Using". It would be nice if the code :

  Using MyPen 
     Graphics.FromImage(bmp).DrawLine(MyPen, p1, p2)
  End Using

is just as efficient where I first define the pen in one place and then draw with the Using ...End Using block.
