通过以上步骤,你可以成功地将std::string转换为LPCWSTR,并在Windows API中使用它。请注意,静态变量在stringToLPCWSTR函数中的使用可能会导致线程安全问题,因此在实际应用中需要谨慎处理。
LPCWSTR stringToLPCWSTR(std::string orig) { size_t origsize = orig.length() + 1; const size_t newsize = 100; size_t convertedChars = 0; wchar_t *wcstring = (wchar_t *)malloc(sizeof(wchar_t)*(orig.length() - 1)); mbstowcs_s(&convertedChars, wcstring, origsize, orig.c_str(...
