I am tring to shift enter chararter by 2 . That mean char "A" to "c".

How it should work:
1> I collect QString from LineEdit.
2>Than get each ASCII value of SQtring
3> Add 2 to ASCII Value
4> Convert it to QString
5> Show it to Thru LineEdit2

QString pass3;
    QChar ch;
    int i,chValue;
 
 
    // Get Data
    QString str = ui->lineEdit->text();
 
    // QString to char array;
    for(i=0; i<=str.size();i++)
    {
        // converted to number
        ch=str.at(i).toAscii();
        chValue = ch.toAscii();
 
        chValue=chValue + 2;
 
        // Number to Charecter and string in QSTRING
        pass3 += QChar(chVale);
 
    }
 
    ui->lineEdit_2->setText(pass3);

QString pass3;
    QChar ch;
    int i,chValue;


    // Get Data
    QString str = ui->lineEdit->text();

    // QString to char array;
    for(i=0; i<=str.size();i++)
    {
        // converted to number
        ch=str.at(i).toAscii();
        chValue = ch.toAscii();

        chValue=chValue + 2;

        // Number to Charecter and string in QSTRING
        pass3 += QChar(chVale);

    }

    ui->lineEdit_2->setText(pass3);

So what is the problem exactly? If you make 'chVale' a char, it should work fine.

[askrina]

These problem are showen on building:

1>'QChar::QChar(char)' is private
2>within this context
3>'chVal' was not declared in this scope

[aamer4yu]

what happens if you change chValue a char, instead of int ? as wysota said ?
Also the code and error doesnt match,, in error u say 'chaVal' but in code I dont see any such variable
Also in pass3 += QChar(chVale); is chVale declared ?

[askrina]

Ok, It was my typing mistake.

I changed chVale to chValue and again compiled it and i got following error :


1>'QChar::QChar(char)' is private
2>within this context

And please tell what does 1 and 2 means.

[wysota]

It means you need to learn C++.

Are you using Qt4 or Qt3? Qt4 (which is what your profile suggests you are using) surely has a public constructor taking a char so you shouldn't be getting that error.

Yes, I am new to C++ and I m using QT4 with sdk.

Can u show how to do that.

[wysota]

How to do what? Please provide the exact code you have now because right now we are chasing ghosts.

This is what I want:

And what is the error? With lines and everything, please.

BTW. You are modifying the value of the character by 2 but then you are not using it anywhere.

[askrina]

I have changed it.
AND I am getting following error
1>'QChar::QChar(char)' is private
2>within this context
