MessageDialog and Volume

[ bancika @ 27.11.2004. 21:40 ] @

1) probaj funkciju CreateMessageDialog iz dialogs unita...prekopiraj je celu u svoju formu i promeni red gde stoji

Code:

Windows.DrawText( canvas.handle,
            PChar(LoadResString(ButtonCaptions[B])), -1,
            TextRect, DT_CALCRECT or DT_LEFT or DT_SINGLELINE or
            DrawTextBiDiModeFlagsReadingOnly);

u nesto tipa

Code:

Windows.DrawText( canvas.handle,
            'Hello Fanta', -1,
            TextRect, DT_CALCRECT or DT_LEFT or DT_SINGLELINE or
            DrawTextBiDiModeFlagsReadingOnly);

i zameni jos na par mesta gde se javlja Caption za dugmice u ono sto ti treba

2) ne bih znao :)

pozdravi

Probaj ovo:

Code:

function SetMicrophoneVolume(bValue: Word): Boolean;
{ Private declarations }

function Tform1.SetMicrophoneVolume(bValue: Word): Boolean;
var                          {0..65535}
  hMix: HMIXER;
  mxlc: MIXERLINECONTROLS;
  mxcd: TMIXERCONTROLDETAILS;
  vol: TMIXERCONTROLDETAILS_UNSIGNED;
  mxc: MIXERCONTROL;
  mxl: TMixerLine;
  intRet: Integer;
  nMixerDevs: Integer;
begin
  // Check if Mixer is available
  nMixerDevs := mixerGetNumDevs();
  if (nMixerDevs < 1) then
  begin
    Exit;
  end;

  // open the mixer
  intRet := mixerOpen(@hMix, 0, 0, 0, 0);
  if intRet = MMSYSERR_NOERROR then
  begin
    mxl.dwComponentType := MIXERLINE_COMPONENTTYPE_SRC_MICROPHONE;
    mxl.cbStruct := SizeOf(mxl);

    // get line info
    intRet := mixerGetLineInfo(hMix, @mxl, MIXER_GETLINEINFOF_COMPONENTTYPE);

    if intRet = MMSYSERR_NOERROR then
    begin
      ZeroMemory(@mxlc, SizeOf(mxlc));
      mxlc.cbStruct := SizeOf(mxlc);
      mxlc.dwLineID := mxl.dwLineID;
      mxlc.dwControlType := MIXERCONTROL_CONTROLTYPE_VOLUME;
      mxlc.cControls := 1;
      mxlc.cbmxctrl := SizeOf(mxc);

      mxlc.pamxctrl := @mxc;
      intRet := mixerGetLineControls(hMix, @mxlc, MIXER_GETLINECONTROLSF_ONEBYTYPE);

      if intRet = MMSYSERR_NOERROR then
      begin
      {
       // Microphone Name
          Label1.Caption := mxlc.pamxctrl.szName;

        // Min/Max Volume
        Label2.Caption := IntToStr(mxc.Bounds.dwMinimum) + '->' + IntToStr(mxc.Bounds.dwMaximum);
      }
        ZeroMemory(@mxcd, SizeOf(mxcd));
        mxcd.dwControlID := mxc.dwControlID;
        mxcd.cbStruct := SizeOf(mxcd);
        mxcd.cMultipleItems := 0;
        mxcd.cbDetails := SizeOf(Vol);
        mxcd.paDetails := @vol;
        mxcd.cChannels := 1;

       vol.dwValue := mxlc.pamxctrl.Bounds.lMinimum;
       vol.dwValue := mxlc.pamxctrl.Bounds.lMaximum;
        vol.dwValue := bValue;
        intRet := mixerSetControlDetails(hMix, @mxcd,
          MIXER_SETCONTROLDETAILSF_VALUE);
        if intRet <> MMSYSERR_NOERROR then
          MessageBeep(16);
      end
      else
       MessageBeep(16);
    end;
    intRet := mixerClose(hMix);
  end;
end;
