If you create a graphic file Resource like this:
1. context-click on your
Project Name in the Solution Explorer treeview
2. select the
Properties menu item at the bottom of the menu
3. click on the
Resources item in the menu at left
4. open the
Add Resource drop-down
5. select
Add Existing File item
6. select your graphic file
Then, anytime you want to use the resource in code, you'll do something like:
button1.BackgroundImage = Properties.Resources.ResourceName;
Intellisense should show you the names of available resources as soon as you have typed "Properties.Resources."
If that's not working for you, then please respond with details on exactly how you have added the graphic file resource to your Project.
