PRB: 16-Bit Resource Table Limitation Under Win32s

   "OFFSETOF(pResWrite) < 0xfffc"   or   "OFFSETOF(pResWrite) < 0xfffe"
				

MORE INFORMATION

Note that the limitation discussed in this article is the size of the 16- bit resource table created by Win32s and not the size of the resource data section. In Win32s version 1.15a and earlier, there is a limitation on the resource data section to be less than 64K, but that limit is eliminated in Win32s versions 1.20 and later.

The size of the resource data section is determined by using the DUMPBIN tool on the 32-bit side. The following line appears:

where xxxx is the size of the resource data section. However, this does not provide any information on the 16-bit resource table described earlier.

The resource table size can be calculated as follows (in bytes):

      2 + (N1 * 8) + (N2 * 16) + N3 + N4

   N1 = Number of resource types (icon, menu, etc.)
   N2 = Number of resources (all resource types)
   N3 = Sum of the lengths of all string IDs (including resource types
                                              that have string IDs)
   N4 = Number of string IDs
				

The result of the calculation should be less than 32K. If a resource is specified in several languages, count it only once in N2.
