[SOLVED] SQLite3 in a C::B GUI
« on: April 20, 2018, 03:53:28 am »
There are a LOT of tutorials on youtube showing how to use SQLite3 with a C::B console program. ONE shows a GUI through the use of wxSQLite3, but this guy doesn't speak or explain anything. And some of what he does is obscure as hell! Will someone puhleeeez point me to a link that goes step by step on how I can implement SQLite3 in a C::B GUI program? I'm doing this right now using Qt (they have the SQL drivers built in and accessing them is a breeze), but I detest using their hybrid C++! I want pure C++ through C::B to build my SQLite3 programs.

I've tried adding the sqlite3.c and sqlite3.h to a C::PB GUI and immediately get a mile of errors in the buffer.h file:

Am I getting all of these errors because I'm adding sqlite3.c to mix in with the *.cpp files?

I just want to know how to use SQLite3 with a C::B GUI. That's all! Help me get this sorted out and I'll get out of your hair for life. I've been fighting this for over a month. Haven't said a word here because those here who know how to do things are already stretched thin as hell. And I'm not talking abt queries and stuff like that. I can do sql. I just want to know how to access SQLite3 in a C::B GUI.

Post an link to wxSQLite sample code; and, I might get a chance in  the next week to figure it out.

Hi stahta01:

I run Linux. I think wxSQLite3 might just be a wrapper for Windows. When I tried to use it, I recall it used *.dll files. But I might be wrong on it being strictly for Windows. I hope I am. Anyway, here are a few links:

https://www.youtube.com/watch?v=KHjSiVQbvX0

https://github.com/utelle/wxsqlite3

https://en.wikipedia.org/wiki/WxSQLite3

https://forums.wxwidgets.org/viewtopic.php?t=37675

If wxSQLite3 is a Windows-only SQLite3 wrapper for C++, then how can SQLite3 be used in a C::B GUI on Linux? I use SQLite3 in C::B console programs. That's easy. But when I try to use the same SQLite3 files in a C::B GUI, all hell breaks loose!

I hope you can figure this out. I sure can't. And thank you for trying. Than you very much for that.

I'm pretty sure wxSqlite has been dead for over a decade.  Use wxSqlite3 instead.

Just build and install the library according to the instructions.

Here's a minimal example that only opens a database (or creates one if it doesn't exist).  Create an empty wxWidgets project, add an empty cpp source file and paste this into it:

Code
// For compilers that support precompilation, includes "wx/wx.h".
#include "wx/wxprec.h"

#ifdef __BORLANDC__
    #pragma hdrstop
#endif

// for all others, include the necessary headers (this file is usually all you
// need because it includes almost all "standard" wxWidgets headers)
#ifndef WX_PRECOMP
    #include "wx/wx.h"
#endif

#include <wx/wxsqlite3.h>

class MyFrame : public wxFrame
{
    public:
        MyFrame( wxWindow* parent, int id = wxID_ANY, wxString title = "Demo",
                 wxPoint pos = wxDefaultPosition, wxSize size = wxDefaultSize,
                 int style = wxDEFAULT_FRAME_STYLE|wxTAB_TRAVERSAL );
        ~MyFrame();
    private:
        wxSQLite3Database db;
};

MyFrame::MyFrame( wxWindow* parent, int id, wxString title, wxPoint pos,
                  wxSize size, int style )
        :wxFrame( parent, id, title, pos, size, style )
{
    db.Open("data.db");

    if(db.IsOpen())
    {
        SetTitle("db opened");
    }
}

MyFrame::~MyFrame()
{
    if(db.IsOpen())
    {
        db.Close();
    }
}

class MyApp : public wxApp
{
    public:
        virtual bool OnInit()
        {
            MyFrame* frame = new MyFrame(NULL);
            frame->Show();
            return true;
        }
};

wxIMPLEMENT_APP(MyApp);

Add the wxSqlite3 library to the code::blocks projects link libraries the build and run.

Hi New Pagodi:

Works like a charm! A million thanks for your help.
