LAST VERSION - 1.1
07-Dec-10

This library provides a dialog box to select a color in three color models - RGB (Red, Green, Blue), HSL (Hue, Saturation, Lightness), and HSB (Hue, Saturation, Brightness). This is not a program, this is a function that you can use in your scripts. This function is similar to the _ChooseColor() from Misc.au3 library that is included in the AutoIt package. UDF is fully compatible with the ColorPicker.au3 (v1.5) and can be used as a custom function for a "Color Chooser" dialog box (see examples). Also there is a tool (pipette) to get the color from the screen. I recommend to first read description inside the library. Please play with this UDF and post any comments and suggestions. Enjoy.

Yashid, I get the following errors when running example 1:

F:\AutoIt\Other People Projects and Examples\Yasheid\Color Choser UDF\ColorChooser.au3(1295,47) : ERROR: CP_WM_COMMAND(): undefined function.
        CP_WM_COMMAND($hWnd, $iMsg, $wParam, $lParam)
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^
F:\AutoIt\Other People Projects and Examples\Yasheid\Color Choser UDF\ColorChooser.au3(1469,59) : ERROR: CP_WM_SETCURSOR(): undefined function.
        $Result = CP_WM_SETCURSOR($hWnd, $iMsg, $wParam, $lParam)

Yashid, I get the following errors when running example 1...

With this code you also get an error, but the code is absolutely correct. Do not pay any attention to it.

If (IsDeclared('A')) And ($A = 1) Then
    MyFunc()
EndIf

[Yashied]

Small update.

This requires really hard work. Thanks Yashied. I appreciate it...

when R = 250, G = 250, B = 250, return value of ColorChooser function is H = 160, S = 0, L = 240

why here H = 160, instead of　Ｈ = 0 ?

why here H = 160, instead of　Ｈ = 0 ?

When Saturation is 0 it really doesnt matter what the Hue is because its still going to be grey/black/white and its very common in this instance for the hue to be set to the center of the colour wheel which is 160 in this case.

EDIT: Freakn great UDF....the color picker tool is just gravy!
