[Solved]Program exited with code 0

gayu

no through editor i am entering the Ques and answer also
The xml file generates, from the xml file to database it is entering, bt the Ques is entering into the database correctly.
The options i.e Qt is a |cross platform\ appln framework is the Answer stmt.
Bt this enters the database as null value only not the stmt or phrase

AlekseyOk

My code is not processing statements with asterisk (*), so you should add this by yourself ;-)

gayu

No thats not my problem.

After replacing my code with the code wat u give me to replace with, the following is the table entries now.

The following table for Question entries

4724 | What is Qt? | NULL | Tamil Nadu | EnglishI | 1 | 1

4725 | Who is Sachin? | NULL | Tamil Nadu | EnglishI | 1 | 1

The table entries for Answers is,
More than one time it is entering like the following

APNo | Statement1 | Statement2 | Option1 | QNo

80563 | | NULL | | 4724

80564 | | NULL | | 4724

80565 | | NULL | | 4724

80566 | | NULL | | 4725

80567 | | NULL | | 4725

80568 | | NULL | | 4725

The actual Answer table should be like,

APNo | Statement1 | Statement2 | Option1 | QNo

80563 | Qt is a | NULL | cross platform application framework | 4724

80564 | | is sachin | A famous crickter | 4725

But i am not getting like this. I am just getting the empty values for stmt1,option.

gayu

Instead of the following code

@
int mainForm::parseOption(int ind,QString option, QString &stmt1, QString &phrase)
{
QTextStream cout(stdout, QIODevice::WriteOnly);
int j = 0;
int index = ind;
cout<<"index---\n"<<index<<endl;
cout<<"311 : parseOption : "<<option<<endl;
cout<<"option[index]--\n"<<option[index]<<endl;
while(option[index] != '|')
{
stmt1[j] = option[index];
cout<<"stmt1[j]\n"<<stmt1<<endl;
if(option[index]=='\0')
{
cout<<"option[index]-----\n"<<option[index]<<endl;
stmt1[j] = '\0';
option[0] = '\0';
return -1;
// return (index);
}
index++;
j++;
}
stmt1[j] = '\0';
stmt1=stmt1.replace( "{sub}","<sub>");
stmt1=stmt1.replace( "{/sub}","</sub>" );

while(option[index] != '\')
{
phrase[j] = option[index];
index++;
j++;
}

cout<<"425 : "<<stmt1<<endl;
j = 0;
index++;
cout<<"option[index]-->\n"<<option[index]<<endl;
phrase=phrase.replace( "{sub}","<sub>" );
phrase=phrase.replace( "{sub}","<sub>" );
cout<<"Phrase value"<<phrase<<endl;
phrase[j] = '\0';
cout<<"436 : "<<phrase<<endl;

return (index + 1);

}
@

I added the code u asked me to add

@

```
 int pos1 = option.indexOf('|');
```
```
 if (pos1 != -1)
```
```
 {
```
```
   stmt1 = option.left(pos1);
```

     int pos2 = option.indexOf('\\', pos1);

```
     if (pos2 != -1)
```
```
     {
```

         phrase = option.mid(pos1, pos2 - pos1);

```
     }
```
```
else
```
{
// there is no '|' symbol in option
```
 }
```

@

AlekseyOk

I've already checked my code and it works fine (actually, you can change line 9 with phrase = option.mid(pos1 + 1, pos2 - pos1); to remove leading '|').

Input: "Qt is a |cross platform application framework."
Output: stmt1 = "Qt is a "
phrase = ""cross platform application framework"

gayu

I tried by that too phrase = option.mid(pos1 + 1, pos2 – pos1); bt nw th answer table is not get updated.
i.e the Questions are entering to the database, but the answers are not entering to the database in answer table.

AlekseyOk

@
QString option = "Qt is a |cross platform application framework\.";
int pos1 = option.indexOf('|');
if (pos1 != -1)
{
stmt1 = option.left(pos1);

int pos2 = option.indexOf('\\', pos1);
if (pos2 != -1)
{
    phrase = option.mid(pos1, pos2 - pos1 + 1);
}

}
else
{
qDebug("there is no '|' symbol in option");
}

qDebug("stmt1=%s, phrase=%s", qPrintable(stmt1), qPrintable(phrase));
@

Output: "stmt1=Qt is a , phrase=|cross platform application framework"

Is this output correct for your task?

gayu

The '|' and '' should not seen in the database. Otherwise the output is correct.
But, the thing is i need the stmt2 also enter to the database.
for eg

|Lotus\ is our national flower.

In the above stmt, lotus is the phrase, and is our national flower is the stmt2.
That stmt2 is not entering in database.

And also tried with that code, also remain the same problem, the answers are not entering into the database.

AlekseyOk

try to replace '' with '\'

gayu

ya i tried by replacing '' with '\' Still it is not get inserting into the Answer table.

gayu

So in my code instead of return -1, i replaced it by returning the index as return index.

As in the switch case, in if condition i'm checking the condition as

@
if(option[index]=='\0')
{
cout<<"option[index]-----\n"<<option[index]<<endl;
stmt1[j] = '\0';
option[0] = '\0';
//return -1; instead of this
return (index); added this
}
@

instead of this condition i replaced it as,

@
if(index!=-1) instead of this

if((((Short *)object)->options[i])[index]!='\0') added this
{
query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values ("" + stmt1 + "", NULL,"" + phrase + ""," + temp2.setNum(qNo) + "," + temp2.setNum(((Short *)object)->ptno[i+1])+",1)");
}
@

With the above condition what i've added it working fine.

It is inserting into the Ques table and also in Ans table now. whether it is right or nt. Do you have any idea about this. Please tell me

AlekseyOk

What is an "Answer table"?! We didn't speak about any insertion of data to Answer table. Check your SQL-queries for correctness.

gayu

The answer table is where the options and stmt get parsed i.e Qt is a |Cross platform appln framework. is to be in the answer table.
Surely i'll check the SQL-queries where i've to do the corrections.

AlekseyOk

First of all - print all values on the screen
Second - change SQL-query builder to the next:

@
query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values (?, ?, ?, ?, ?, ?)");
query.addBindValue(stmt1);
query.addBindValue(QVariant(QVariant::String)); // NULL string
query.addBindValue(phrase);
query.addBindValue(temp2.setNum(qNo));
query.addBindValue(temp2.setNum(((Short *)object)->ptno[i+1]));
query.addBindValue(1);
@

gayu

Sorry for asking you again and again, please tell me
Instead of the following code
@
query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values ("" + stmt1 + "", NULL,"" + phrase + ""," + temp2.setNum(qNo) + "," + temp2.setNum(((Short *)object)->ptno[i+1])+",1)");
@

I've to add this code
@
query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values (?, ?, ?, ?, ?, ?)");
query.addBindValue(stmt1);
query.addBindValue(QVariant(QVariant::String)); // NULL string
query.addBindValue(phrase);
query.addBindValue(temp2.setNum(qNo));
query.addBindValue(temp2.setNum(((Short *)object)->ptno[i+1]));
query.addBindValue(1);
@

If means by adding this code it is showing the error as request for member ‘addBindValue’ in ‘query’, which is of non-class type ‘QSqlQuery

For printing the values on screen i already added the following code.

@index = parseOption(index,((Short *)object)->options[i],stmt1,phrase);
cout<<"index : "<<index<<"\n"<<stmt1<<"\n"<<phrase<<endl;
QString text11;
stmt1temp=stmt1;
cout<<"stmt1temp\n"<<stmt1<<endl;
stmt1=stmt1temp;
cout<<"stmt1\n"<<stmt1<<endl;
phrasetemp=phrase;
cout<<"phrasetemp\n"<<phrasetemp<<endl;
phrase=phrasetemp;
cout<<"phrase\n"<<phrase<<endl;@

AlekseyOk

change '.' to '->'
What is an output of cout << *?

gayu

index : 41
Qt is a
cross platform appln framework
stmt1temp
.
stmt1
.
phrasetemp
cross platform appln framework
phrase
cross platform appln framework

AlekseyOk

As I can see your output doesn't contain any NULL-value. So, I think you have errors somewere else... Possibly, in SQL-table (e.g. wrong field type).
For what are you make such assignments:

@
...
stmt1temp=stmt1;
cout<<"stmt1temp\n"<<stmt1<<endl;
stmt1=stmt1temp;
...
@
?

gayu

For eg if i am entering the answer like this.
Android is a |Linux-based operating system\ designed primarily for touchscreen mobile devices.

In the following code,
@
index = parseOption(index,((Short *)object)->options[i],stmt1,phrase);
cout<<"index : "<<index<<"\n"<<stmt1<<"\n"<<phrase<<endl;
@
The stmt1temp,stmt1 is considered as Android is a
As you know, the phrasetemp,phrase is the same Linux-based operating system
By the following code,

@
stmt1=parseQuestion(stmt1); // function called for replacing tilde,cape symbol to angluar brackets
cout<<"stmt1--\n"<<stmt1<<endl;
stmt2temp=parseStepNo(stmt1,i,aPNo);
cout<<"stmt2temp\n"<<stmt2temp<<endl;
cout<<"\nThis is the apno value required"<<aPNo<<endl;
stmt2=stmt2temp;
cout<<"This is STatement2 value"<<stmt2<<endl;
@

The stmt1 is taken for stmt2 i.e designed primarily for touchscreen mobile devices.
The assignments are mainly made for parsing the options.

gayu

Actually i missed some thing in the previous post

index : 40
Qt is a
cross platform appln framework

stmt1temp
Qt is a
stmt1
Qt is a
phrasetemp
cross platform appln framework
phrase
cross platform appln framework

After this
text11insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values ("Qt is a ", NULL,"cross platform appln framework",4816,4816,1)

Then,

index : 41
Qt is a
cross platform appln framework
stmt1temp
.
stmt1
.
phrasetemp
cross platform appln framework
phrase
