QT + Problem + execute

**anouar2002** · 20th January 2012, 06:01

Hi,,
Please, I really need help as soon as possible.
I developed a Qt application that interacts with a SQL Server database. All goes well until today.
I did not like my base so I decided to create another. What prompts me to change several instructions in all files of my code.
When I run my code again, I found it full of errors (almost 45) and these are errors in files I've ever seen (no sources or headers or xml) I decided to dc drop the base change and I returned to the old version of my code (I ranking) but here: it's a surprise the same errors are dominated my own version (that one hour before it worked perfectly). I do not know what to do? I can not redo all the work because I have to drop this Saturday
Please please help me (I apologize for this long story but I'm really stuck)

Thank you for your long story. Would you care to share information that might actually tell us what sort of errors you are getting, where they are coming from etc.?

**anouar2002** · 20th January 2012, 06:12

There are 45 error :
most of them contains path
For example :
In file included

and more..

**ChrisW67** · 20th January 2012, 06:18

... and what line of your code triggers these error messages? What are the lines around that line?

**anouar2002** · 20th January 2012, 06:21

the problem is those error are not in files that's i wrote it. But in some file .h , that first time i see them.

**ChrisW67** · 20th January 2012, 06:28

Copy and paste the entire error message or at least the first 10 lines or so.

What is at or around line 8 of file ..\Gestion\/details2.h?

**anouar2002** · 20th January 2012, 06:41

sorry didn't unserstand ??

**ChrisW67** · 20th January 2012, 06:47

The error message contains two lines that reference your source code. The files are ..\Gestion\/details2.h and ..\Gestion\details2.cpp (on your D drive).
Your source code is the thing that changed... therefore we are looking for problems in that source that are cascading into other things that get included.

Also, do a clean build: Build menu, Clean All followed by Build menu, Build All

**anouar2002** · 20th January 2012, 06:55

for the files details.h and details2.h, the error are on line 1 : #include "details2.h"
and line 8 : #include <QtGui>

( i did a build and clean and nothing as result)

**ChrisW67** · 20th January 2012, 07:01

What is on lines 1 through 7 of details2.h?

**anouar2002** · 20th January 2012, 07:04

#ifndef DETAILS2_H
#define DETAILS2_H

#include <QDialog>

namespace Ui {
class details2;
#include <QtGui>

**ChrisW67** · 20th January 2012, 07:10

My best guess at this point is that you need to close the namespace:

Qt Code:

Switch view

#ifndef DETAILS2_H
#define DETAILS2_H
 
#include <QDialog>
 
namespace Ui {
class details2;
}  // <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< this line missing
 
#include <QtGui>

#ifndef DETAILS2_H
#define DETAILS2_H

#include <QDialog>

namespace Ui {
class details2;
}  // <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< this line missing

#include <QtGui>

there is } :

Qt Code:

Switch view

#ifndef DETAILS2_H
#define DETAILS2_H
 
#include <QDialog>
 
namespace Ui {
    class details2;
 
#include <QtGui>
#include <QtSql>
#include <QtCore>
 
}

#ifndef DETAILS2_H
#define DETAILS2_H

#include <QDialog>

namespace Ui {
    class details2;

#include <QtGui>
#include <QtSql>
#include <QtCore>

}

**ChrisW67** · 20th January 2012, 07:16

Move it unless you really want to try to put qt into the Ui namespace.

**anouar2002** · 20th January 2012, 07:21

I move it but another error comes at line 67 : else without a previous if
but there is a if ,,,???????????

Qt Code:

Switch view

qry.bindValue(":Code_Barre",numero);
                qry.bindValue(":Nom_Lot",nom);
                qry.bindValue(":Fiche_Allocation",fiche);
                qry.bindValue(":Id_Casier",valeur);
                if(qry.exec()){
 
                            QMessageBox::information(this,"Information","L'operation d'ajout a Ã©tÃ© rÃ©alisÃ©e avec succÃ¨ss !");
                            ui->lineEdit->clear();

Look harder at line 10!

**anouar2002** · 20th January 2012, 07:34

i correct many errors ( i don't know from where they comes ) but now : Error is
The program ended suddenly.

**ChrisW67** · 20th January 2012, 08:14

Run the program in a debugger. When it crashes look at the backtrace. I do not intend to hand hold you through fixing every little quirk in your code.
