 |

Ok, I know how to take RGB and get to HEX with it, but for the life
of me, I can't figure out how to reverse it back to RGB.....
Anyone have any idea's or clue's for me on this one??
Thanks in advance,
-Garrett

Take each RGB hex value (individually), and do this:
@sum($%%value, 0)
This converts it back to decimal.

Depending on what you're trying to do, the following code will show useful things:
| Code: |
%%vdscolor = @sum($00123456,0)
%%hex = @hex(%%vdscolor,8)
%%blue = @sum($@substr(%%hex,3,4),0)
%%green = @sum($@substr(%%hex,5,6),0)
%%red = @sum($@substr(%%hex,7,8),0)
info VDS color: %%vdscolor@cr()Hex color: %%hex@cr()Red: %%red@cr()Green: %%green@cr()Blue: %%blue

Can someone tell me how to convert a color value from the registry (ex. 0 78 152) to HEX? (does VDS 3.51 understand HEX?)

Yes, you can use the @hex() function.
While @format() will limit numbers to the length supplied, it
will NOT add leading zeros if the string is shorter, so you
must modify string length to get 2 digit RGB hex values.
| Code: |
%%num1 = 0
if @greater(2, @len(@format(@hex(%%num1), 2.0)))
%%num1 = "0"@format(@hex(%%num1), 2.0)
else
%%num1 = @format(@hex(%%num1), 2.0)
end
%%num2 = 78
if @greater(2, @len(@format(@hex(%%num2), 2.0)))
%%num2 = "0"@format(@hex(%%num2), 2.0)
else
%%num2 = @format(@hex(%%num2), 2.0)
end
%%num3 = 152
if @greater(2, @len(@format(@hex(%%num3), 2.0)))
%%num3 = "0"@format(@hex(%%num3), 2.0)
else
%%num3 = @format(@hex(%%num3), 2.0)
end
INFO %%num1%%num2%%num3

But how can I divide a value in 3 numbers? bacause if I take it out of the registry (%%BackgroundColor = @REGREAD(CURUSER,Control Panel\Colors,Background) I get 0 78 152. Is it possible to divide that into 3 numbers?

Use the PARSE command. If your 0 78 152 is in %%NUMBER, it would look like:
OPTION FIELDSEP," "
PARSE "%A;%B;%C",%%NUMBER |

| Could you parse it using @chr(32) as the field sep? |

another question:
Can I set a style to a color with DIALOG SET,STYLE1,BLACK ? (I downloaded a color picker a while ago, but I can't find it anymore)

No.
Styles are not treated like other elements in VDS. You must
add all styles you expect to use when you create the dialog.
BTW, here's a VDS Color Picker for HTML compatible colors:
