问题描述
我知道如何将CStringT变量的内容分配给BSTR或CComBSTR变量，但是我应该如何去做呢?我有一个包含BSTR参数的C ++ Com方法.我想将该参数的内容分配给CStringT，以便能够在转换回BSTR并返回之前使用CStringT的字符串操作方法.如何初始化此CString并进行赋值?如果有的话，请发送一个代码示例.
I know how to assign the contents of a CStringT variable to a BSTR or CComBSTR variable, but how do I go the other way? I have a C++ Com method that includes a BSTR argument. I want to assign the contents of that argument to CStringT, to be able to use CStringT''s string manipulation methods before converting back to BSTR and returning. How do I initialize this CString and make the assignment? Please send a code example, if you have one. Thanks!

CAtlString str(_T(这是我的字符串！"));
BSTR bstr = str.AllocSysString();
我认为这对您有帮助.
CAtlString str(_T("This is my string!"));
BSTR bstr = str.AllocSysString();
i think this will help u.
