Dear Colleagues,

I try modify SampleUaConsole example of UA_SDK

I try to return a return value of UaClient::read() method.


See code below (adapted from SimpleCient.cpp in Examples of UA_SDK)

string output;
...
readDataValue = readResponse->Results()[0];
WideString x = readDataValue.Value().ToString();
output= readDataValue.Value().ToString().c_str();

The last line cause a type converion error!

Can you help me?

Hi Roberto,

The compiler is telling you that WideString::c_str returns wchar_t* and std::string has no corresponding assignment operator.
