[SOLVED] Fast search method

[Jyang772]

Does Qt provide a fast way to search specific strings through multiple files containing hex data? If not, what algorithm is best suited for this kind of search?

Right now I am using indexof.

       if(temp.toHex().indexOf("564952555300") != -1){

       return item.name;
       qDebug() << "FOUND";
       qDebug() << filetoOpen;
        file.close();
       }

       if(temp.toHex().indexOf("563252555300") != -1){
        qDebug() << "FOUND";
        qDebug() << filetoOpen;
        file.close();
       }

       if(temp.toHex().indexOf("5642324555300") != -1){
        qDebug() << "FOUND";
        qDebug() << filetoOpen;
        file.close();
       }

Hi,

Not directly no. You can have a look at the Qt Concurrent module. With it you can run your function several times in parallel.
