I have a button on my form with the property Image set to closeImage.bmp.
But I want to make this undone so i can set the property again but then to closeImage.jpg.
I could delete the value of the property Image but then it still exists in the dialogscreen
And there is no button to delete this resource. Also I have noticed that a folder will
be automaticly created in the Solution Explorer with my image.
What is the proper way to erase the image that is set in the property Image.
