'This may be copied into the design code in it's entirety......
'Create a New Standard Exe and add the following objects to the Form:
'In Project select Componts and Check 'Microsoft Common Dialog Control 6.0' - Click Apply and OK
'Place it anywhere on the Form
'If desired, Set Form1 StartupPosition to 2 - Center Screen (This cannot be done during runtime)
'The placement and properties of the following will be set by the program (if indicated Names are used)
'Add Eight (8) CommandButtons to the Form with the following Names:
'cmdClearL
'cmdClearRGB
'cmdConvert - Index 0
'cmdConvert - Index 1
'cmdDisplayL
'cmdDisplayRGB
'cmdPickColor
'cmdResetAll
'Add a Label (Default Name Label1) and copy it into an array (0 to 11)
'Add Two (2) PictureBoxes (Default Names - Picture1 and Picture2)
'Add a TextBox (Default Name Text1) and copy it into an array (0 to 2)
'Add a TextBox (Default Name Text2)
'You're done! When the program runs the placement and properties will be set
'to useable values.
