How to get current volume of iphone

I want to get the current volume of iphone. I did some searches and found MPVolumeView which is used to adjust the volume. But it can't be used to get the current volume.
Is there a way to get that value? I don't want to adjust the volume, just want to get the value and display it.

Have you tried the method here: [http://blog.stormyprods.com/2008/09/proper-usage-of-mpvolumeview-class.html]?

    I recently purchased songs from itunes via my pc and I dont know how to get them onto my iphone? When I click the sync button it says I will lose all the music currently on my iphone.. Help

    If you're syncing with a different iTunes library than the one you previously synced with, then there is no way around it. You're gonna loose the old data. The only way round it would be to make sure that all the music files on your iPhone is also in your iTunes library. If you still have access to the computer with the old library, you could copy the files on to an external harddrive, and then import them into your new iTunes library.
    If it is in fact the same library, then the music currently on your iphone, is also in your itunes library. Just make sure that the artists/albums/playlists, or whatever you sync contains these tracks, that you allready have on your phone and don't want deleted. What i do is, i create a playlist specifically for my iPhone, and i set it up to only sync with this playlist. Whenever i hear a track from my iTunes library or buy a new track that i want on my phone, i just drag it to this playlist and next time i synchronize, it's there without deleting anything else.

  • How to get current rowindex of clicked object in cr2008 preview control

    hi
    i want to get selected raw data when user click on crystal report 2008 preview control.
    i can achieve using following code for particular row no.
    Dim repReport as new ReportDocument
    repReport.Rows(RowIndex).Item(ColumnIndex)
    how to get current rowindex ? 
    Thanks
    Sanjiv Sharma

    Only way I can think of is to use the rowset controller from the InProc RAS SDK. Here is a snippet of a sample code on how to:
    //Load the report
    if (clientDoc != null) {
    //create metadata structure
    RowsetMetaData rowSetMetaData = new RowsetMetaData();  rowSetMetaData.setDataFields
    (clientDoc.getDataDefinition().getResultFields());
           Fields fields = rowSetMetaData.getDataFields();
           String colName,colTypeName;
           int colType, len;
           Field field;
           HashMap colNames = new HashMap();
           HashMap colTypes = new HashMap();
           for (int i = 0; i < fields.size(); i++) {
                   field = (Field) fields.get(i);
                   colName =field.getDisplayName(FieldDisplayNameType.description, Locale
    .ENGLISH);
                   colNames.put("COL"+i,colName);
           colType = getColTypeFromVariant(field.getType().toVariantTypeString());
           len=field.getLength();
                  //Placeholder
            //add column metadata to data structure or XML
            Object colValue;
            int rowCount=0;
            if (getMaxRows() != 0) {
                   RowsetCursor rowsetCursor = clientDoc.getRowsetController(). createCursor
    (null, rowSetMetaData);
                  //Setting the batch size to make sure that you get back all the
                  //rows by setting the batch size.
                        clientDoc.getRowsetController().setRowsetBatchSize (rowsetCursor
    .getRowset().getTotalRecordCount());
               //Getting the Results back starting from the first row
               RowsetCursor resultCursor = clientDoc.getRowsetController(). createCursor(null,
    rowSetMetaData);
               resultCursor.moveTo(0);
                  while (!resultCursor.isEOF()) {
                      for (int i = 0; i < fields.size(); i++) {
                               colName=(String)colNames.get("COL"+i);
                               colTypeName=(String)colTypes.get("COL"+i);
    colValue=record.getValue(i);
                                //Placeholder
    //add row data to data structure or XML
    resultCursor.moveNext();

    Hi all
    I have two ViewObject EmplyesView and DeptView
    How to get Current row of ViewObject DeptView in the DoDML methode of EmplyesView

    OK, we can play this game on and on...
    I'll ask for a use case (http://en.wikipedia.org/wiki/Use_case) and you don't give any info we don't already know. After an other 10 posts we probably know what you real problem is and can give you the advice which you could have gotten in the fist place.
    So please take some time and describe the problem as if you would ask your mother for help. Tell us how the data model is build and how the VO are related. Is there any input from an user involved? Which information from the other view do you need? How do you get to the doDML method? Is there a button in the ui involved?

  • How to get current assigned participant id?

    Hi mates,
    This might be a basic questions, but useful for me :)
    How to get current assigned participant id from screenflow? Or How to pass it as an argument from interactive activity?
    Below is what I tried.
    Participant.id or Instance.participant.id - returns login user id
    Thanks

    Hi,
    Please correct me if I understood wrong.
    You want to know whether an instance is assigned or not and if assigned then you want to fetch the assigned participant id.
    If this is your requirement then please find the code below and make the necessary changes into it.
    Write the following code in screen flow automatic activity but before that you need to pass the instanceid as argument to the screen flow.
    In the process as well as screen flow layer make an instance variable instanceid as Int.
    Then make an argument variable instanceidArg as Int in both the screenflow and process layer and map accordingly so that it will take the instanceid from process layer to the screen flow layer.
    Assign instanceid = id.number; in process layer automatic activity but before the global interactive activity where you have maped the screen flow.
    Write the following code in screen flow automatic activity.
    logMessage("============= instanceid ==============" + instanceid); //instanceid is the id of the instance that you have passed from process layer.
    ProcessService ps;
    InstanceFilter instF = InstanceFilter();
    ps.connectTo(url : Fuego.Server.directoryURL, user : "<userid>", password : "<password>"); //In studio the userid and password will be same
    logMessage("Connected");
    instF.create(processService : ps);
    instF.searchScope = SearchScope(participantScope : ParticipantScope.ALL, statusScope : StatusScope.ONLY_INPROCESS);
    //<ProessId Name> is the id of the process where you want to know the assighed participant id
    instF.addAttributeTo(variable : VarDefinition.processid, comparator : Comparison.CONTAINS, value : "/" + "<ProessId>");
    instF.addAttributeTo(variable : VarDefinition.INSTANCE_NUMBER, comparator : Comparison.IS, value : Int(instanceid));
    Fuego.Papi.Instance[] instances = getInstancesByFilter(ps, filter : instF);
    foreach (instance in instances) {
    logMessage("Assigned ?: " + instance.participantId.empty);
    logMessage("instance.participantId: " + instance.participantId);
    ps.disconnectFrom();
