我必须将两个CString
变量和两个long
变量连接在一起
CString
。我找到了一个我用过的格式函数:
CString str = "Some Data";
str.Format("%s%d", str, 123);
但它给出了错误。这是错误日志:
\AudWinSockXCtrl.cpp(410) : error C2440: 'initializing' : cannot convert from 'const char [10]' to 'ATL::CStringT'
with
[
BaseType=wchar_t,
StringTraits=StrTraitMFC
]

Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or
function-style cast

我们在Java中使用像toString()
这样的函数吗?
答案 0 :(得分:1)
CString str = _T("Some Data");
str.Format(_T("%s%d"), str, 123);
在此处阅读_T
和<tchar.h>
:Generic-Text Mappings in Tchar.h 。

sprintf(OutputBuffer,“%s%d”,str,123);
强制CString被评估为CStringA :: Goto,Project-&gt; Properties-&gt; Configuration Properties-&gt; General。 在右侧,您将获得“字符集”行,将其更改为“未设置”
