  errmm..  guess I/we were wrong.   it turns out the code sample shown above doesn't work.  It is because the Red and Blue were switched between RGB and ARGB

  Visual Studio 6.0 RGB numeric format: BBBBBBBBGGGGGGGGRRRRRRRR

  Visual Studio .NET 2005 ARGB numeric format: AAAAAAARRRRRRRRGGGGGGGGBBBBBBBB

  where A=alpha, R=red, G=green, B=blue.

  So you must actually flip around the red and blue components.

  Code to convert old RGB into new ARGB:

  Color clr = Color.FromArgb(Convert.ToInt32(pRGBColor));
  clr = Color.FromArgb(255, (int)clr.B, (int)clr.G, (int)clr.R);

  Code to convert new ARGB back into old RGB

  Color clr = cmdButton.BackColor;
  clr = Color.FromArgb(0, clr.B, clr.G, clr.R);

  Hope this helps someone down the road!

  It appears that the problem is because in VB6 we stored the colors as RGB - and we are working with ARGB in .NET.

  The code is not working because the Alpha Level is not being set. One solution for this is

  button1.BackColor = Color.FromArgb(255,Color.FromArgb(Convert.ToInt32(strColor)));

  strColor = "16776960";
  cmdReadyColor.BackColor = Color.FromArgb(Convert.ToInt32(strColor));

  Is the code I use to set the BackColor. I read the color as a text string (as represented in first line) - then I try to set the back color using the integer value.

  Thanks Nitin - yes, that is a very good way to fix the issue. Better than what I came up with.
