Question

I know this is a very basic question but sometimes it happens that you loose your basic concept 🙂
Tried Goggling but not enough support on that too.

I am using predefined library from one of our device owner. They have a declaration as :

unsigned char FamilySerialNum[0][8]

This variable gets the serial number of the device in hexadecimal. Now i am using this library in Qt to display the serial number in QLineEdit. For that I need to convert it to QString.

Tried using QString::UTF8, strcpy(), sprintf() etc. but getting garbage data.

So can anyone suggest me some way to get it done.

Hello Try the function below…

QString getStringFromUnsignedChar(unsigned char *str)
{

    QString s;
    QString result = "";
    int rev = strlen(str); 

    // Print String in Reverse order....
    for ( int i = 0; i<rev; i++)
        {
           s = QString("%1").arg(str[i],0,16);

           if(s == "0"){
              s="00";
             }
         result.append(s);

         }
   return result;
}
