From: David F on 16 Jun 2005 04:55 I am getting the following 2 error messages from the compiler: f:\development\projects 2005\fc\fc.cpp(296) : error C2664: 'wsprintfW' : cannot convert parameter 1 from 'LPSTR' to 'LPWSTR' Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast f:\development\projects 2005\fc\fc.cpp(373) : error C2664: 'FindFirstFileW' : cannot convert parameter 1 from 'const char *' to 'LPCWSTR' Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast My code does not have "wsprintfW" & "FindFirstFileW" ! What I do have is "wsprintf" & "FindFirstFile". Anybody heard about such behavior of the C++ compiler? Thanks, David

There is *no* function "wsprintf" and "FindFirstFile"! There is either an ANSI- or UNICODE-Version, and therefor either "wsprintfA" or "wsprintfW" ("FindFirstFileA" or "FindFirstFileW"). What you see is just a define which will be set to one of the abouve depending on the "character set". By default in VC2005 the default is UNICODE. To be flexible you should include "tchar.h" and pass your strings in the following way: _T("") Then your string will be correctly passed, regardless of ANSI/UNICODE setting... -- Greetings Jochen My blog about Win32 and .NET http://blog.kalmbachnet.de/
From: David McCabe on 16 Jun 2005 05:12 You have UNICODE defined. When you compile with Unicode, Windows API functions that take strings resolve to their Unicode variants, which have a 'W' suffix. They then require Unicode strings as parameters. Either change your strings to be Unicode strings (constants should have an L prefix), or change your compile options to use "multi-byte character sets". -- David "David F" <David-White(a)earthlink.net> wrote in message news:uRns%23ElcFHA.2696(a)TK2MSFTNGP09.phx.gbl... >I am getting the following 2 error messages from the compiler: > > f:\development\projects 2005\fc\fc.cpp(296) : error C2664: 'wsprintfW' : > cannot convert parameter 1 from 'LPSTR' to 'LPWSTR' > > Types pointed to are unrelated; conversion requires > reinterpret_cast, C-style cast or function-style cast > > > > f:\development\projects 2005\fc\fc.cpp(373) : error C2664: > 'FindFirstFileW' > : cannot convert parameter 1 from 'const char *' to 'LPCWSTR' > > Types pointed to are unrelated; conversion requires > reinterpret_cast, C-style cast or function-style cast > > > My code does not have "wsprintfW" & "FindFirstFileW" ! > What I do have is "wsprintf" & "FindFirstFile". > > Anybody heard about such behavior of the C++ compiler? > > Thanks, > David > >
From: Nishant Sivakumar on 16 Jun 2005 05:13 You've got UNICODE defined. Remove the definition or convert all your string literals to Unicode compliant ones. -- Regards, Nish [VC++ MVP] http://www.voidnish.com http://blog.voidnish.com "David F" <David-White(a)earthlink.net> wrote in message news:uRns%23ElcFHA.2696(a)TK2MSFTNGP09.phx.gbl... >I am getting the following 2 error messages from the compiler: > > f:\development\projects 2005\fc\fc.cpp(296) : error C2664: 'wsprintfW' : > cannot convert parameter 1 from 'LPSTR' to 'LPWSTR' > > Types pointed to are unrelated; conversion requires > reinterpret_cast, C-style cast or function-style cast > > > > f:\development\projects 2005\fc\fc.cpp(373) : error C2664: > 'FindFirstFileW' > : cannot convert parameter 1 from 'const char *' to 'LPCWSTR' > > Types pointed to are unrelated; conversion requires > reinterpret_cast, C-style cast or function-style cast > > > My code does not have "wsprintfW" & "FindFirstFileW" ! > What I do have is "wsprintf" & "FindFirstFile". > > Anybody heard about such behavior of the C++ compiler? > > Thanks, > David > >

Does your project use Unicode. This is a snippet from winuser.h where wsprintf is defined WINUSERAPI int WINAPIV wsprintfA( OUT LPSTR, IN LPCSTR, ...); WINUSERAPI int WINAPIV wsprintfW( OUT LPWSTR, IN LPCWSTR, ...); #ifdef UNICODE #define wsprintf wsprintfW #else #define wsprintf wsprintfA #endif // !UNICODE As you can see wsprintf is defined as a macro for wsprintfW och wsprintfA depending on UNICODE or not. /David David F wrote: > I am getting the following 2 error messages from the compiler: > > f:\development\projects 2005\fc\fc.cpp(296) : error C2664: 'wsprintfW' : > cannot convert parameter 1 from 'LPSTR' to 'LPWSTR' > > Types pointed to are unrelated; conversion requires > reinterpret_cast, C-style cast or function-style cast > > > > f:\development\projects 2005\fc\fc.cpp(373) : error C2664: 'FindFirstFileW' > : cannot convert parameter 1 from 'const char *' to 'LPCWSTR' > > Types pointed to are unrelated; conversion requires > reinterpret_cast, C-style cast or function-style cast > > > My code does not have "wsprintfW" & "FindFirstFileW" ! > What I do have is "wsprintf" & "FindFirstFile". > > Anybody heard about such behavior of the C++ compiler? > > Thanks, > David > > |
