Dynamic list of formatting

• How to enumerate, and select in C++ in the list of formats PCM published by a recording device in Windows 7?

  I used the following to open a wave in the device (USB codec) under XP:

  waveInOpen ((HWAVEIN*) & hWaveIn, idWaveIn, (LPWAVEFORMATEX) & wfx, MainDlg (DWORD)-> handle, 0, CALLBACK_WINDOW);

  How could I do this in Windows 7?  The device is open with its default and no format approaches I tried to work.  Default format is listed in the applet sound like 1-channel, 16-bit, 44100 Hz (CD quality). What I need is listed as 2-channel, 16-bit, 32000 Hz (quality FM Radio).

  Method 1:
  the value input to the PCM format
  PropVariantInit(&varConfigBuf);
  HR = pProps-> GetValue (PKEY_AudioEngine_DeviceFormat & varConfigBuf);
  If ((hr == S_OK) & (varConfigBuf.vt == VT_BLOB))
  {
  if(varConfigBuf.blob.cbSize>0)
  {
  WAVEFORMATEX * pWaveFormatExBlob = (WAVEFORMATEX *) (varConfigBuf.blob.pBlobData);
  If (pWaveFormatExBlob-> nChannels! = wfx.nChannels |)
  pWaveFormatExBlob-> nSamplesPerSec! = wfx.nSamplesPerSec)
  {
  WAVEFORMATEXTENSIBLE * pWaveFormatExtensibleBlob =(WAVEFORMATEXTENSIBLE*) pWaveFormatExBlob;

  pWaveFormatExBlob-> wFormatTag = WAVE_FORMAT_EXTENSIBLE;
  pWaveFormatExBlob-> nChannels = wfx.nChannels;
  pWaveFormatExBlob-> nSamplesPerSec = wfx.nSamplesPerSec;
  pWaveFormatExBlob-> wBitsPerSample = wfx.wBitsPerSample;
  pWaveFormatExBlob-> which nBlockAlign = wfx.nBlockAlign;//pWaveFormatExBlob-> nChannels * pWaveFormatExBlob-> wBitsPerSample/8;
  pWaveFormatExBlob-> wfx.nAvgBytesPerSec;//pWaveFormatExBlob-> nSamplesPerSec = nAvgBytesPerSec * pWaveFormatExBlob-> which nBlockAlign;
  pWaveFormatExtensibleBlob-> Samples.wValidBitsPerSample = pWaveFormatExBlob-> wBitsPerSample;
  pWaveFormatExtensibleBlob-> dwChannelMask = 3;
  GUID sf = (GUID) pWaveFormatExtensibleBlob-> sous-format;
  pWaveFormatExtensibleBlob-> sous-format = KSDATAFORMAT_SUBTYPE_PCM;

  HR = pProps-> SetValue (PKEY_AudioEngine_DeviceFormat, varConfigBuf);
  if(hr == S_OK)
  {
  HR = pProps-> Commit();
  }
  on the other
  {
  ShowMessage (AudioError (hr));
  }
  }

  This method adds a new entry (2 channels, 16-bit, 32000 Hz) to the list of formats under the Advanced tab, but the camera is still recording mono.

  Method 2:
  IAudioClient * pAudioInterface = NULL;
  HR = pEndpoint-> Activate (__uuidof (IAudioClient), CLSCTX_ALL,(void**) & pAudioInterface);

  WAVEFORMATEX * pDeviceFormat;
  HR = pAudioInterface-> () IsFormatSupported
  AUDCLNT_SHAREMODE_EXCLUSIVE,
  AUDCLNT_SHAREMODE_SHARED,
  & wfx,
  & pDeviceFormat
  );
  CoTaskMemFree (pDeviceFormat);

  HR = pAudioInterface-> Initialize (AUDCLNT_SHAREMODE_EXCLUSIVE, 0, 5000000, 0, & wfx, NULL);
  SAFE_RELEASE (pAudioInterface)

  Initialize() returns 0, but no changes to the format of the device.

  Is it possible to enumerate the list of formats provided by the sound applet, and then select one of the people I know is supported by the device?  It's probably pretty clear from the above, but in case not, I am scratching around the dark here and any help is appreciated (even with disparaging remarks included!).

  Thank you

• creating a dynamic list within a static list

  Hello

  I use 5 APEX with universal theme and so I have the static navigation on the left side menu.

  I have the following in the list:

  Orders

  Admin

  View profile

  It is a static so each link to a page of the list.

  However I want to have it so that when I click on the controls bind it then displays a dynamic list of the commands in the menu, then it should look like this,

  Orders

  Order 1

  Order 2

  Order 3

  Admin

  View profile

  So I have a dynamic list that creates the list commands. How can I "attach" it in the static so that the parent is the link of orders in the static list?

  Thanks for your help.

  If none of the entries in the list are dynamic, then the entire list must be dynamic. See using lists/Navigation Menu to universal theme APEX5 for a similar scenario.

• Dynamic lists for recommendation using CSElement

  Hello

  I want to know what should be in CSElement to create dynamic lists for recommendation.

  If I create just a list with two columns as asset Id and the type of assets that will suffice?

  Dynamic list recommendations requires a list named " AssetList " and 2 columns 'assetid' and 'assettype.

  We can use any method to generate this list.

  Looks like my CSElement

  I used the most basic that is hard coding as

  And it works.

  Thanks nice to point me the finger in the right direction.

• Using #WORKSPACE_IMAGES # with the names of dynamic list of Image, not to hardcode

  I hope someone can help me with this request.

  I am developing an Apex application but I am learning as I go along by examples of Google search and read the tutorials, etc.  I am trying to create a slideshow based on a dynamic list of Image names. First, I created an apex_collection in a header containing the names of the image process, I need (view/column APEX_COLLECTIONS. C001) I then created a Page called P81_IMAGE_NAME element. I'm trying to loop through the collection and display the pictures in a slide show.   I have a HTML Page with the following code in the Source of the region (found the code in an example online)... Please can someone tell me where I can add the following PL/SQL code so that #WORKSPACE_IMAGES # nom_image may contain the names of images dynamically recoveries rather then hard-coded image names as in the < div Section of the Source region - Code I want to add somewhere, don't know where it add or even if it will work

  Declare cursor c1 is

  Select c001

  of apex_collections

  where collection_name = "CO_IMAGES";

  Start

  A1 to c1 loop

  : P81_IMAGE_NAME: = c1. C001;

  < img src = "#WORKSPACE_IMAGES & P81_IMAGE_NAME" alt = "Slideshow Image" / >

  end loop;

  end;

  -End

  -The code which displays images, I found (Harcoded in the < div section)

  < script type = "text/javascript" >

  function slideSwitch() {}

  var $active = $("#slideshow IMG.active");

  If ($active.length == 0) $active = $("#slideshow IMG:last");

  This allows to take images in their order of appearance in the tag

  var $next = $active.next () .length? $active.next)

  : $('#slideshow IMG:first');

  Uncomment the 3 lines below to shoot images in random order

  var $sibs = $active.siblings ();

  var rndNum = Math.floor (Math.random () * $sibs.length);

  var $next = $($sibs [rndNum]);

  $active.addClass('last-active');

  $next.css ({opacity: 0.0})

  .addClass ('active')

  . Animate ({opacity: 1.0}, 3000, function() {})

  $active.removeClass ('active last active');

  });

  }

  {$(function()}

  setInterval ('slideSwitch()', 3000);

  });

  < /script >

  < style type = "text/css" >

  / * the value width and height to match your images * /.

  {#slideshow}

  position: relative;

  height: 400px;

  }

  Depends on the number of images. How are they involved?

  With a small number (e.g. 10-20), you can simply use a page element to register the handset img reference items and she as a substitution string in the region existing HTML. For more information, it would be preferable to use a report.

  On the approach of page element:

  1. create the point P81_IMAGES of the page as an element of the display only. The value of the Condition Never element so it is not included in the rendered page and the security attribute point escape special characters No.

  2. create a page process before header (sequenced to run once the collection created if that is done at this point in the process):

  begin
  
    :p81_images := null;
  
    for img in (
      select c001 src
      from apex_collections
      where collection_name = 'CO_IMAGES')
    loop
      :p81_images := :p81_images || ' '
    end loop;
  
  end;
  

  3 refer to the value of the element in the HTML source of the region

  
  
  
  
  
    &P81_IMAGES.
