Color shining

Hello

I made form with option to change color with CommonDialog (.ShowColor).

After the user press OK I get the color from: CommonDialog.Color property.

Is any body know how can I get the Shining of that color. (the number that represented by Lum in the CommonDialog) ???

Thanks for any help.

Use the ColorRGBToHLS() API function to convert your RGB value into HLS.

If this function is not available to you, but are familiar with C, the MSDN contains a source code for the conversion. Search for "RGB to HLS" (without the quotes) in MSDN and you'll get it. You can either put this code in a DLL and call it from your VB program or convert the code to VB.
