gha custom component - no icon just a transparent hole

Hi Guys,

I am starting to create a custom 0.7 grasshopper component with Visual Basic 2010 Express following the guide from Ben Sitler.

Most stuff is working fine but my custom Icon is not properly showing up in Grasshopper. There is just a transparent hole where it should be (in tab menu & on the component box & etc).

I listed a schematic/simplified version of my component below. The icon was added to the project resource file and with the name 'ICON'.

The mentioned guide is supposed to be for 0.6 ... might that be the problem and i have to register the custom icon differently?

Thank you for your help

Ciao

Hi KT,

this looks correct. Can you upload the image file that is ICON to this thread as an attachment?

Hi David,

Thank you for your quick response. I attached the icon to my original post. I added this to the resource file of my project and gave it the name ICON. Its a 24x24 pixel png file with transparent background but i also tried it with the same file saved as bmp and gif.

So probably the problem is hidden somewhere else... in some visual studio setting or settings file I am going to check now.

Anyway. I was actually surprised that its so easy to write own components for GH and have an own gha file to incorporate this custom functionality. Great work! :)

Ciao
KT

ps: No the id was changed before posting so no one else takes it :)

Hi KT,

very strange indeed. I'd like to get to the bottom of this. Can you email me the entire project + resource files via email? ( david@mcneel.com )
