字符串。 TCHAR LPWCS LPCTSTR CString。什么是这里，简单快速 [英] Strings. TCHAR LPWCS LPCTSTR CString. Whats what here, simple quick

问题描述

TCHAR szExeFileName[MAX_PATH]; 
GetModuleFileName(NULL, szExeFileName, MAX_PATH);

CString tmp;
lstrcpy(szExeFileName, tmp);
CString out;
out.Format("\nInstall32 at %s\n", tmp);
TRACE(tmp);

错误（格式化）：

error C2664: 'void ATL::CStringT<BaseType,StringTraits>::Format(const wchar_t 
*,...)' : cannot convert parameter 1 from 'const char [15]' to 'const wchar_t

我只想得到当前路径从它启动并复制到一个CString，所以我可以在其他地方使用它。我目前只是试图通过TRACE'ing它看到的路径。但字符串，字符，字符数组，我不能得到所有的海峡。

I'd just like to get the current path that this program was launched from and copy it into a CString so I can use it elsewhere. I am currently just try to get to see the path by TRACE'ing it out. But strings, chars, char arrays, I can't ever get all the strait. Could someone give me a pointer?

推荐答案

我的猜测是在Unicode模式下编译。

My guess is you are compiling in Unicode mode.

尝试在_T宏中包含您的格式字符串，这是为了提供始终正确的提供常量字符串参数的方法，而不管您是以Unicode还是ANSI模式编译：

Try enclosing your format string in the _T macro, which is designed to provide an always-correct method of providing constant string parameters, regardless of whether you're compiling in Unicode or ANSI mode:

out.Format(_T("\nInstall32 at %s\n"), tmp);
