[Bug 27927] New: Winhttprequest WaitForResponse should process messages

http://bugs.winehq.org/show_bug.cgi?id=27927

           Summary: Winhttprequest WaitForResponse should process messages
           Product: Wine
           Version: 1.3.25
          Platform: x86
               URL: http://netikka.net/dev/winhttpwait.exe
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winhttp
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: ocean04(a)suomi24.fi


Allows application to respond user action while waiting. For example cancel
button.

Example: http://netikka.net/dev/winhttpwait.exe

Click "download". There is time counter, but counter doesn't work. Same thing
with cancel button. Also request should timeout in 30 seconds, but it doesn't?

(Url is just some large exe-file, easier to reproduce problem also using fast
internet connection)

begin
 cancel:=false;
 fhttp:=createoleobject('WinHttp.WinHttpRequest.5.1');
 fhttp.open('GET', edit1.text, true);
 fhttp.send();
 // waiting 30 seconds or user cancel.
 for i:=1 to 30 do
 begin
  if fhttp.WaitForResponse(1) then break;
  application.processmessages;
  label6.caption:='Time: '+inttostr(i);
  if (i=30) or (cancel=true) then
  begin
   if i=30 then showmessage('Timeout') else showmessage('User cancel');
   fhttp.Abort;
   fhttp:=unassigned;
   exit;
  end;
 end;
 memo1.text:=fhttp.Responsetext;
 ...
 ...
end;

procedure TForm1.Button3Click(Sender: TObject);
begin
  cancel:=true;
end;
