[bhadram r. <bha...@ya...>]

 
 
Dear friends, 
       I'd problem in vc++. The problem is i want to call the static method of a class in another header file. But if im calling it is giving linking error
error LNK2001: unresolved external symbol 
 
The program is as under. I want to call the static word_map method of UserQuery class present in UserQuery.h file from TextQuery class present in TextQuery.h header file. But it is giving linking error.I also tried including UserQuery. h in TextQuery header file, but it is saying redeclaration.How to solve the problem. Please help me.
 
Thanking you,
yours sincerely,
bhadram
