[Solved]Program exited with code 0

gayu

I used some cout stmts to check wat the option of index is.
The option[index] is printing as the "|" symbol.
After the stmt1 the "|" is seen and return the option[index] as "|" and returning the index value as +ve value.
Then when coming to the stmt2 it checks the condition, "|" . The condition is not get satisfied returning "-1".

And I also tried wat u said,
@
1.
while(option[index] != '|' &&
2.
option[index] != '\0')
@
It is not taking the phrase value,only it reads the stmt1, and exit from the editor.

AlekseyOk

try to add you check

@
if(option[index]=='\0')
{
stmt1[j] = '\0';
option[0] = '\0';
return -1; //here it returns '-1'
}
@

after the loop if you want to exit with code -1.

Why are you using this loop instead of "QString::indexOf":http://qt-project.org/doc/qt-4.8/qstring.html#indexOf

gayu

Ya i checked by adding the "if" after the loop.
But it doesn't exit from the loop, runs until i stop the execution.

AlekseyOk

Is option a QString?
Is option ends with '\0'?

If 1 and 2 are true than this loop shouldn't be infinite.

gayu

ya the option is QString only.
You asked me to check the "if" by adding it after the loop. By adding it after the loop only becomes infinite.

AlekseyOk

Should this help?

@
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
}
@

gayu

Ya i tried tis by replacing tat, bt it is still the same not exiting from the loop, also printing the stmt as null.

AlekseyOk

You shouldn't use a single backslash in option string, because it will be processed as '.' in second case.
So, before processing, replace single backslashes with doubled or select another symbol

gayu

This means whether you are asking me to use double backslash in the phrase itself or at the end of last stmt i've to put double backslash.

gayu

By trying with this code,

@
1.int pos1 = option.indexOf('|');
2.if (pos1 != -1)
3. {
4. stmt1 = option.left(pos1);
5. int pos2 = option.indexOf('\', pos1);
7. if (pos2 != -1)
8. {
9. phrase = option.mid(pos1, pos2 - pos1);
10 }
11. else
12. {
13. // there is no '|' symbol in option
14. }
@
I am getting this error "commitdb.cpp:1219: error: a function-definition is not allowed here before ‘{’ token" in some other functions.
so i removed this code and compile with the the original code itself.@@

AlekseyOk

add } before else

gayu

Ya i added }
Now it is not exiting from the editor and its working.
But, the question is entering into database finely, the answer is not entering to the database (i.e options) printing the null values for option,stmt1 and stmt2 . Also the null values are entering to database more than once

AlekseyOk

Sorry, I don't understand what you do you want.

Insert some values into some db?
something else?

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?
