Thread: Help with error

I am not a C programmer, but needed to modify a line on a 'C' source file. When I try to compile this file, I get errors relating to a header file (sqltypes.h) thats included and supplied by the compiler. Can anyone help? Here are the errors:

sqltypes.h(114) : error C2061: syntax error : identifier 'SQLHWND'
sqltypes.h(114) : error C2059: syntax error : ';'
sqltypes.h(252) : error C2061: syntax error : identifier 'DWORD'
sqltypes.h(253) : error C2061: syntax error : identifier 'Data2'
sqltypes.h(253) : error C2059: syntax error : ';'
sqltypes.h(254) : error C2061: syntax error : identifier 'Data3'
sqltypes.h(254) : error C2059: syntax error : ';'
sqltypes.h(255) : error C2061: syntax error : identifier 'Data4'
sqltypes.h(255) : error C2059: syntax error : ';'
sqltypes.h(255) : error C2059: syntax error : '['
sqltypes.h(256) : error C2059: syntax error : '}'

Thanks!!!
