Custom components issue n. 2

Hi all.

For one of the components mentioned in my other question (http://www.experts-exchange.com/Programming/Languages/Pascal/Delphi/Q_28348188.html), I can't have the icon correctly displayed.

I created a dcr file with ResourceBuilder. Here I added a bitmap 32x32 256 colors calling it with the same of the component in uppercase. The in the unit I use to register the component I wrote the directive

{$R name_of_resource_file.dcr}

For some component works well, for others not and I can't find the difference.

Thanks in advance for any advice.

Icon must have same name as class name: TMyClass  -->  TMYCLASS.
Use name notation depending on size of image:

TMYCLASS BITMAP "MyClassImg24x24.bmp"
TMYCLASS16 BITMAP "MyClassImg16x16.bmp"
TMYCLASS32 BITMAP "MyClassImg32x32.bmp"

Make sure that your bitmap is a real 256 colors (8bit).
