Ok, finally it repeated. The problem is that the thread requires
a message pump if it owns a window. It is _neither_ a problem related
to ICS nor to Delphi! You'll see the same freeze when you create a window
by calling Classes.AllocateHwnd(). Uncomment the commented lines below
to make it working:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TForm1 = class(TForm)
Button1: TButton;
Edit1: TEdit;
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
TTestThread = class(TThread)
private
FHandle : HWND;
procedure WndProc(var MsgRec: TMessage);
protected
procedure Execute;override;
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
{ TTestThread }
procedure TTestThread.WndProc(var MsgRec: TMessage);
begin
MsgRec.Result := DefWindowProc(FHandle, MsgRec.Msg, MsgRec.wParam,
MsgRec.lParam);
end;
procedure TTestThread.Execute;
var
Msg: TMsg;
begin
// PeekMessage(Msg, 0, 0, 0, PM_NOREMOVE); // Initialize thread's message
queue
FHandle := Classes.AllocateHWnd(WndProc); // Create a hidden window
{while not Terminated do
begin
while PeekMessage(Msg, 0, 0, 0, PM_REMOVE) do
begin
if Msg.message = WM_QUIT then
Terminate
else begin
TranslateMessage(Msg);
DispatchMessage(Msg);
end;
end;}
Sleep(1000);
end;
end;
procedure TForm1.FormCreate(Sender: TObject);
begin
with TTestThread.Create(true) do Resume;
end;
end.
