The error "Cannot Reuse String Constants" will be returned by the Resource Compiler if you have used the same ID value to define two different string constants.

For example, the following error is returned when compiling the resource file:

Cannot Reuse String Constants

MORE INFORMATION
The following sample code can be used to demonstrate the problem.

Sample Code
  StringTable begin 1, "one" 2, "two" 3, "three" 1, "four" end

Note that "one" and "four" have the same value. This error may be less noticeable if you are using both decimal and hexadecimal notation in your RC file. In the following example, 0x010 and 16 have the same value and generate the error:

0x010, "hex 10"

10, "ten"

11, "eleven"

15, "fifteen"

16, "sixteen"
