QT + Problem + execute

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):eek:

Re: QT + Problem + execute

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.?

Re: QT + Problem + execute

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

Re: QT + Problem + execute

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

Re: QT + Problem + execute

Re: QT + Problem + execute

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

Re: QT + Problem + execute

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

Re: QT + Problem + execute

sorry didn't unserstand ??

Re: QT + Problem + execute

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

Re: QT + Problem + execute

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)

Re: QT + Problem + execute

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

Re: QT + Problem + execute

#ifndef DETAILS2_H
#define DETAILS2_H

#include <QDialog>

namespace Ui {
class details2;
#include <QtGui>

Re: QT + Problem + execute

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

Code:

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

Re: QT + Problem + execute

there is } :

Code:

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

Re: QT + Problem + execute

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

Re: QT + Problem + execute

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

Code:

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();
                            ui->lineEdit_2->clear();
                            ui->lineEdit_3->clear();}
                            ui->comboBox->setCurrentIndex(0);
 /*line 67*/             else {
 
                        QMessageBox::warning(this,"Erreur","L'operation d'ajout a rencontrÃ© un problÃ¨me !");

Re: QT + Problem + execute

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.
