[python-win32] Question on .pyw extension in Python

2005-11-28 Thread flame burns 
I've installed Python 2.4 on my pc which runs Windows xp. I downloaded scripts from some sites which uses .pyw extension. When I use them the script runs without popping up a console. But when I try to write my own script with pyw extension it doesn't work. Can any one help me?

[python-win32] mciSendCommand from win32 ???

2005-11-28 Thread [EMAIL PROTECTED] 
Hi !

I want to call mciSendCommand to record a music in Windows.

I want to do same thing like in this code (Delphi):

procedure TForm1.OpenMedia;
var
  MyOpenParms: TMCI_Open_Parms;
begin
  Flags:=mci_Wait or mci_Open_Element or mci_Open_Type;
  with MyOpenParms do
begin
  dwCallback:=Handle; // TForm1.Handle
  lpstrDeviceType:=PChar('WaveAudio');
  lpstrElementName:=PChar('');
end;
  MyError:=mciSendCommand(0, mci_Open, Flags,Cardinal(@MyOpenParms));
  if MyError = 0 then FDeviceID:=MyOpenParms.wDeviceID;
end;

procedure TForm1.RecordMedia;
var
  MyRecordParms: TMCI_Record_Parms;
  set_parms: MCI_WAVE_SET_PARMS;
begin
  set_parms.wFormatTag  := WAVE_FORMAT_PCM;
  set_parms.wBitsPerSample  := 16;
  set_parms.nChannels   := 1;
  set_parms.nBlockAlign := 
(set_parms.nChannels*set_parms.wBitsPerSample) div 8;
  set_parms.nSamplesPerSec  := 44100;
  set_parms.nAvgBytesPerSec := ((set_parms.wBitsPerSample) *
set_parms.nChannels *
set_parms.nSamplesPerSec) div 8;
  MyError:=mciSendCommand(FDeviceID,MCI_SET,
   MCI_WAIT
   or MCI_WAVE_SET_FORMATTAG
   or MCI_WAVE_SET_BITSPERSAMPLE
   or MCI_WAVE_SET_CHANNELS
   or MCI_WAVE_SET_SAMPLESPERSEC
   or MCI_WAVE_SET_AVGBYTESPERSEC
   or MCI_WAVE_SET_BLOCKALIGN,
   Cardinal(@set_parms));
  Flags:=mci_Notify;
  with MyRecordParms do
  begin
dwCallback:=Handle;  // TForm1.Handle
dwFrom:=0;
dwTo:=1;
  end;
  MyError:=mciSendCommand(FDeviceID, mci_Record, Flags, 
Longint(@MyRecordParms));
end;

procedure TForm1.StopMedia;
var
  MyGenParms: TMCI_Generic_Parms;
begin
if FDeviceID <> 0 then
  begin
Flags:=mci_Wait;
MyGenParms.dwCallback:=Handle;  // TForm1.Handle
MyError:=mciSendCommand(FDeviceID, mci_Stop, Flags,Longint(MyGenParms));
  end;
end;

procedure TForm1.SaveMedia(OrgFileName,FileName:string);
  type// not implemented by Delphi
PMCI_Save_Parms = ^TMCI_Save_Parms;
TMCI_Save_Parms = record
dwCallback: DWord;
lpstrFileName: PAnsiChar;  // name of file to save
  end;
var
  MySaveParms: TMCI_Save_Parms;
begin
  if FDeviceID <> 0 then
  begin
  // save the file...
Flags:=mci_Save_File or mci_Wait;
with MySaveParms do
  begin
dwCallback:=Handle;
lpstrFileName:=PChar(FileName);
  end;
MyError:=mciSendCommand(FDeviceID, mci_Save, Flags,
Longint(@MySaveParms));
  end;
end;

procedure TForm1.CloseMedia;
var
  MyGenParms: TMCI_Generic_Parms;
begin
  if FDeviceID <> 0 then
  begin
Flags:=0;
MyGenParms.dwCallback:=Handle; // TForm1.Handle
MyError:=mciSendCommand(FDeviceID, mci_Close, Flags, 
Longint(MyGenParms));
if MyError = 0 then
  FDeviceID:=0;
  end;
end;


1. Can I do it ?
2. If not, what is the solution (I haven't Delphi... I have only 
freeware things)


Thanx for help: dd

Just to clarify: the .pyw extension simply means: run this
Python script without creating a console window. This is
generally what you want if you have a program which is
GUI-based. You can run *exactly* the same program with a
console window simply by renaming it to .py.

In general, you'll want to name your scripts .py until
you've debugged everything, That way, any errors will
appear on your console window.

If you haven't already, have a look at the FAQ:

http://www.python.org/doc/faq/

and in particular the Python Windows FAQ:

http://www.python.org/doc/faq/windows.html

Try http://www.freepascal.org/ and Lazarus.
Or, there is a small DirectSound example, see the PyWin32 help.

Re: [python-win32] Error calling win32pdh.EnumObjectItems

2005-11-28 Thread Mark Hammond 
It looks like you have an old win32all version (it looks like it was fixed
in win32all-154).  This should be fixed in all pywin32 versions available
from sourceforge.
