Thread: Segmentation fault

I don't know which ones are good, but here are some C++ wrappers:
SQLite CVSTrac

You forget things when you deal with low-level stuff like C, and it also leads to more bugs, which is exactly why you are recommended to use a C++ wrapper, and not the C library directly.

In that case, remove the strcmp code and whatever else you don't need to demonstrate the problem. If they are wrong, you are going to get comments about them. Hence, they just distract from your problem. Either get them right or remove them until you are ready to add them in.

There appears to be a CompareTo method that uses the same concept in C#.

Anyway, you have yet to do what Salem stated: check the actual error code (also, the extended error codes).

Here I go for what you all have advised to me. I found a wxSQLite3 Library which is a C++ + wx wrapper of SQLite.

Code:

#include "DataBase.h"
#include <string>
#include <wx/wxsqlite3.h>
#include <wx/msgdlg.h>

bool CanClose(void)
{
    wxSQLite3Database DB;
    wxSQLite3ResultSet RS;
    DB.Open(_("SysConfig"),_(""),WXSQLITE_OPEN_READWRITE);
    if(DB.IsOpen())
    {
        RS=DB.ExecuteQuery("SELECT config_value from configuration WHERE config_id = 1;");
        if(RS.IsOk())
        {
            wxString WS;
            WS=RS.GetAsString(_("config_value"));
            //wxMessageBox(WS);
            if(WS.IsSameAs(_("YES")))
            {
                DB.Close();
              //  wxMessageBox(_("Returning True"));
                return true;
            }
            else
            {
                DB.Close();
                return false;
            }
        }
    }
    else
    {
        wxMessageBox(_("Can not Open System Files"),_("Error!"));
        DB.Close();
        return false;
    }
    DB.Close();
    return false;
}

But still that myth is unsolved that why sqlite3_prepare_v2 was not working

Well, what does the doc say about how to find out what error occurred when a function fails?
