VM crash when returning unicode

Question

in my native method i have (LPWSTR)pCryptKeyProvInfo->pwszContainerName in UNICODE when i try to return it to the java application using
return (*jEnv)->NewStringUTF(jEnv, pCryptKeyProvInfo->pwszContainerName ), the system crashes.
i verify it my native code using
printf("the contyainer name is %S",pCryptKeyProvInfo-> pwszContainerName)

Answer 1

Try copying the string to a temporary buffer, and use NewString (NewStringUTF is meant to be used with UTF-8 strings; for container names, that have usually no special characters, UTF-8 is ANSI).
int len = wcslen (pCryptKeyProvInfo->pwszContainerName);
wchar_t *buf = new wchar_t[len+1];
wcscpy (buf, pCryptKeyProvInfo->pwszContainerName);
jstring js = jEnv->NewString (buf);
delete[] buf;
