# Retrieving the Decoded String (Safe)

This code snippet shows how to read a QR code and retrieve the decoded string.

## C++

```cpp
#include <eVision/EasyQRCode/EQRCodeReader.h>
```

```cpp
using namespace eVision;

// Image constructor
EImageBW8 srcImage;

// QR code reader constructor
EQRCodeReader reader;

// ...

// Read
std::vector<EQRCode> qrCodes = reader.Read(srcImage);

// Retrieve the data of the first QR code found
std::string decodedString = "";
try
{
  // The QR Code can be fully decoded without user input
  decodedString = qrCodes[0].GetDecodedString();
}
catch (EException exc)
{
  // Handle the exception

  // The QR Code cannot be fully decoded without user input
  // use hexadecimal byte interpretation
  decodedString = qrCodes[0].GetDecodedString(EByteInterpretationMode_Hexadecimal);
}
```
