Arno confirmed your message.
I looked at the code.
You are probably right. But I think the cure is to fix XSocketDeallocateHWnd
(in wsocket.pas) so that all other unit using it is fixed at once:
function XSocketDeallocateHWnd(Wnd: HWND): boolean;
begin
SetWindowLong(Wnd, 0, 0); // <== ADDED
Result := DestroyWindow(Wnd);
end;
With this fix, the line "SetWindowLong(FWindowHandle, 0, 0);" can be removed
from DeallocateSocketHWnd:
procedure TCustomWSocket.DeallocateSocketHWnd;
begin
{$IFDEF DELPHI1}
DeallocateHWnd(FWindowHandle);
{$ELSE}
{ Wilfried added check for existing window }
if FWindowHandle = 0 then
Exit;
{ Remove the object reference from the window }
// SetWindowLong(FWindowHandle, 0, 0); <=== REMOVED
{
}
{ if Destructor call's here and it is wrong thread it will not
}
{ so no need to check Thread Id here, it is done in the
eadDetach }
{ method
ndowHandle); }
if XSocketDeallocateHWnd(FWindowHandle) then
FWindowHandle := 0;
{$ENDIF}
end;
Can you verify it works with your test case ?
Thanks !
