To convert a char* to a QString you can use the QString constructor that takes a QLatin1String, e.g: QString string = QString(QLatin1String(c_str2)) ; 还有其他多种方法: 方法一 --- #define G2U(s) ( QTextCodec::codecForName("GBK")->...
// example for CString::CString CString s1; // Empty string CString s2( "cat" ); // From a C string literal CString s3 = s2; // Copy constructor CString s4( s2 + " " + s3 ); // From a string expression CString s5( 'x' ); // s5 = "x" CString s6( 'x', 6 ); // ...
Inside the CString constructor there is a call to MultiByteToWideChar as follows - And the _AtlGetConversionACP function does not return the CP-UTF8 code page - That is the reason the the CString conversion fails. Tuesday, July 9, 2019 9:19 AM Read this article on converting between UTF-...

function is written in C and doesn't support objects. In this case, coerce theCStringparameter toLPCTSTR, and the function will get a C-styleNULL-terminated string. You can also go the other direction and create aCStringobject by using theCStringconstructor that accepts a C-style string ...
