Error C2664 Cannot Convert Argument

Join them; it only takes a minute: Sign up C2664 error c++ Visual Studio up vote 0 down vote favorite I am trying to modify an old MFC program. After opening the project in https://msdn.microsoft.com/en-us/library/s5b150wd.aspx Visual Studio 2013 there are many errors of the type below. In AviPlay.cpp #include "stdafx.h" #include "AviPlay.h" #define OPEN_AVI_VIDEO "open avivideo" BOOL initAVI() { return mciSendString(OPEN_AVI_VIDEO, NULL, 0, NULL) == 0; } The error thrown is error C2664: 'MCIERROR mciSendStringW(LPCWSTR,LPWSTR,UINT,HWND)' : cannot convert argument 1 from 'const char [14]' to 'LPCWSTR' Should setting the compiler option for Strict to off, or some other compiler option, resolve this error? If not, I can modify the many lines http://stackoverflow.com/questions/25254938/c2664-error-c-visual-studio of code manually. In that case, what might have changed in the last 15 years that would make code like this OK before but not OK now? Thank you in advance. c++ visual-studio-2013 c2664 share|improve this question asked Aug 12 '14 at 1:44 user3931552 11 1 You could try setting the project type to multibyte rather than unicode, but I do not know if that is a valid option when using MFC. –Retired Ninja Aug 12 '14 at 1:48 The project might be set to unicode character set. This would cause your program to link to the wide version of mciSendStringW rather than the multibyte version mciSendStringA. –Beed Aug 12 '14 at 1:49 Setting to multibyte in project properties, general, character set fixed my problem. Thank you very much! –user3931552 Aug 14 '14 at 17:14 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote LPCWSTR tells you it is expecting a wchar_t string, not a char string. By default, all Windows APIs now accept wchar_t strings (unicode). You can change it back to char strings in the project properties, General page, Character Set. Setting it to 'Use Multibyte char set' will get it working as it used to. share|improve this answer answered Aug 12 '14 at 1:54 ScottMcP-MVP 8,9592613 add a comment| Your Answer dr
Verbs Diet Index 2010-03-28 Error C2664 https://bytes.com/topic/c/answers/63040-compile-error-c2664-why LoadLibraryW cannot convert parameter to LPCWSTR I recently used Microsoft Visual Studio 2008 to write a simple program to load a dynamic link library error c2664 (DLL) module and invoke some of its entry points. I did not expect to get the error message C2664 from the simple LoadLibrary statement:HINSTANCE hinstLib = LoadLibrary("azspellaid.dll"); Error C2664: 'LoadLibraryW': error c2664 cannot cannot convert parameter 1 from 'const char [15]' to 'LPCWSTR' There are two ways of fixing this problem. The first one is to cast the quoted string with a Long Pointer to Const Wide String (LPCWSTR):HINSTANCE hinstLib = LoadLibrary((LPCWSTR)L"azspellaid.dll"); The C2664 error can also be resolved by keeping the original code and changing the character set of the project defaults from "unicode character set" to "multi-byte character set" as shown in this image: © Copyright2012 - Antonio Zamora

P: n/a David Hoffman When I compile it, I get a "error C2664: 'ExtractID' : cannot convert parameter 1 from 'char' to 'char []'" error and I don't understand why. I am just learning C++, so keep it simple. One more note, I have the program compiled using strings instead of char[]; however, I should be able to convert all my strings to char[] and get the program to compile. Right? Here is my code. Thanks. // Written by David Hoffman // Sept 30, 2003 #include
