Creating custom components - how to add a small icon representing a component in the tool palette?

Please keep in mind that I read all the instructions that I could find about adding a component icon to my custom component. And I can do this when we talk about the size of the icon, which is 24x24 pixels. I see an icon when a component is dropped on a form. However, I do not see a small 16x16 icon that should be displayed when viewing the tool palette.

I read that I should name two other BMP files that are contained in the DCR file, for example:

MyComponentName16 [for BMP 16x16 file]

MyComponentName32 [for BMP 32x32 file]

Unfortunately, this does not seem to work, I tried to restart Delphi several times in the hope that this might be the case when you are not updating anything, but without any success.

Any ideas?

You can try to clear the cache of the IDE package:

  • remove the component package from your Delphi development environment
  • in the registry, go to the next key
    HKEY_CURRENT_USER\Software\CodeGear\BDS\6.0\Package Cache\
  • find and delete the key corresponding to the name of your package (for example, MyPackage.bpl )
  • now the browser for the next key
    HKEY_CURRENT_USER\Software\CodeGear\BDS\6.0\Palette\Cache\
  • find and delete the key corresponding to the name of your package (for example, MyPackage.bpl )
  • Finally, try installing the package back; it should now appear with the corresponding icons

As another workaround, you can try running the Delphi IDE with an undocumented command line parameter:

 c:\Program Files (x86)\CodeGear\RAD Studio\6.0\bin\bds.exe -nocache
