I have this function from an old extension I wrote. It generates a single random ESRI color. I can't remember where I got it or how I came to this algorithm. Does anyone know if this is still valid with ArcGIS10 and VB2010.
Public Function RandomColor() As ESRI.ArcGIS.Display.IRgbColor Randomize() Dim pRGB As ESRI.ArcGIS.Display.IRgbColor = New ESRI.ArcGIS.Display.RgbColor pRGB.RGB = CInt(16777214 * Rnd() + 1) Return pRGB End Function
