Excel color picker tool to be used with ExcelCOM_UDF

[GreenCan 55]

For the ExcelCOM_UDF users amongst you.

This color pickup tool will allow you to select a color from the standard Excel color palette (same as the Excel color pane).

I think that this could be useful if you plan to develop Excel outputs in AutoIt.

PS. I didn't find a way to implement the color option 2 of the ExcelCOM_UDF where

$iColorIndex > 254 and $hColor Hex value of color is used.

The colors are always different between Excel and Windows. I was tired of trying to understand the differences so this udf only functions with the interior color index

With a little bit of modification, this udf could be used for other means.

Edit: March 6, 21:50 Corrected a bug and color panel now displays the default color.

Thanks ptrex,

I found a bug Corrected it and enhanced a bit The color panel now makes the default color visible.

To make the button visible I had to create a label under it, I couldn't find a better method.

I added a 5th parameter, the default return for the font was white but it needed to be black, so I had to pass 'foreground/background' to the function .

I worked too hard on this thing, costed me 3 evenings... Excel is so weird with the color use, not very Windows standard if you ask me. I would have prefered to use the _ChooseColor function but that was way too easy... Neither possible to create something to make the full 3136 Excel colors selectable. Thanks Bill !
