Convert resource path to relative path

• Use pre-processor symbols and create kind of "compile time-constant"
• Under your property settings to go: Resource -> General -> Preprocessor Definitions -> Edit
• Add your compile time symbol and use VS macros to get relative path, for example: SOLUTION=$(SolutionDir)
• Right click on your .rc file and choose view code
• Use the symbol instead of using relative paths
• For more info check my props folder -> .props file and .rc file
