IBX component in thread

So just go to File -> New -> Other -> Thread Object and put the application code into the Execute procedure, being certain that you use Synchronize to make ANY references to GUI components.

Oh, and yes, within your button's OnClick event, you could do the creation (dynamically).

I've tried doing that, but it just does nothing. I get no error messages either.

Would you mind posting your code?

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, DB, IBDatabase;


type  TForm1 = class(TForm)
    Label1: TLabel;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end; { of class declaration }

type
  mythread = class(TThread)
  private
    { Private declarations }
  procedure opendatabase;
  protected
    procedure Execute; override;
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.Button1Click(Sender: TObject);
begin
mythread.Create(false);
end; { of procedure }

procedure mythread.Execute;
begin
  { Place thread code here }
synchronize(opendatabase);
  end;

procedure mythread.opendatabase;
var db:tibdatabase;
begin
db:=tibdatabase.Create(db);
db.DatabaseName:='z:\track.gdb';
db.Params.add('user_name=sysdba');
db.params.add('password=masterkey');
db.Open;
if db.connected then form1.label1.caption:='connected';
end;

end.

The problem is in the ButtonClick.

procedure TForm1.Button1Click(Sender: TObject);
var
  this MyThread : mythread;
begin
  thismythread := mythread.Create(false);
end; { of procedure }

still dosnt work. the label changes to 'starting' and stays like that

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, DB, IBDatabase;


type  TForm1 = class(TForm)
    Label1: TLabel;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end; { of class declaration }

type
  mythread = class(TThread)
  private
    { Private declarations }
  procedure opendatabase;
  protected
    procedure Execute; override;
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.Button1Click(Sender: TObject);
var f:mythread;
begin
f:=mythread.Create(false);
end; { of procedure }

procedure mythread.Execute;
begin
  { Place thread code here }
synchronize(opendatabase);
  end;

procedure mythread.opendatabase;
var db:tibdatabase;
begin
form1.label1.caption:='starting';
db:=tibdatabase.Create(db);
db.DatabaseName:='z:\track\protrack.gdb';
db.Params.add('user_name=sysdba');
db.params.add('password=masterkey');
form1.label1.caption:='about to open';
db.Open;
if db.connected then form1.label1.caption:='connected' else form1.Label1.caption:='disconnected';

end;

end.

Does the same code work successfully in a non-thread procedure?

yes. works fine if its not in a thread

Hmm. This will take some experimenting. But not today I'm afraid.

Okay not to worry, i've sorted it out.
I've upgraded to the latest IBX, and also found an example of how to use IBconnectionbroker in a thread.

As the only responder, I have no objection, so don't bother waiting on my behalf.

My pleasure. But I would appreciate some attention being given to https://www.experts-exchange.com/questions/20912205/Handled-Abandoned-question.html
