compiling error in exhostappservices.cpp using unicode?
compiling error in exhostappservices.cpp using unicode?
for application using dwgdirect 2.1 in vc6.0, when we set unicode for the project, there will be a compiling error in the .cpp file, "exhostappservices.cpp", which is included in the dwgdirect pack(see below):
compiling...
exhostappservices.cpp
d:\dwgdirect2.10_vc6\ddnonlibs\extensions\exservic es\exhostappservices.cpp(286) : error c2664: 'regenumvaluea' : cannot convert parameter 3 from 'unsigned short *' to 'char *'
types pointed to are unrelated; conversion requires reinterpret_cast, c-style cast or function-style cast
error executing cl.exe.
this error is due to the following code segment(to read a system register item) in the member function "ttffilenamebydescriptor(const odttfdescriptor& descr, odstring& filename)":
tchar* lpvalname = new tchar[nvalnamesize];
lpbyte lpdata = new byte[ndatasize];
nres = ::regenumvalue(hfonts, nindex, lpvalname, &nvalnamesize, null, null, lpdata, &ndatasize);
we note that windows versions of dwgdirect are unconditionally unicode, why does this happen?
then, how to resolve it?

perhaps you did define only _unicode or unicode.
both these symbols should be defined.
