4,151,447 | 4,151,448 | AlarmManager not set from Bootreceiver | <p>because of the fact that the AlarmManager is being cleared when the phone is booted, I created a BootReceiver class that should reset the alarms in this case.
But even though the other code form this class is executed somehow the AlarmManager doesn't get set, so the AlarmReceiver class is never called. Here is part of my code from the BootReceiver class:</p>
<pre><code> Calendar Od = Calendar.getInstance();
Od.set(yearOd, monthOd, dayOd, hourOd, minuteOd);
</code></pre>
<p>AlarmManager am = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);</p>
<pre><code> int id= rebootCursor.getInt(ToDoDBAdapter.ID_COLUMN);
Intent i = new Intent(context, AlarmReceiver.class);
i.putExtra("alarm_message", "stavi_vibracii");
i.putExtra("doVreme",vremeDo);
i.putExtra("doDatum",dateDo);
PendingIntent sender = PendingIntent.getBroadcast(context, id, i, PendingIntent.FLAG_UPDATE_CURRENT);
am.set(AlarmManager.RTC_WAKEUP, Od.getTimeInMillis(), sender);
</code></pre>
<p>I should note that I have registered the BootReceiver and AlarmManger in the Manifest file, and everyhting worked fine when setting the alarms within my app. If somebody had similar problems or have the answer to my question, please let me know..

<pre><code>keybSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
</code></pre>
<p>but this will just be available when the keyboard shows.</p>
<p>but the problem is this: I have a window that has to adjust itself to a new position when the keyboard is visible and when iPhone rotates. When I rotate the iPhone both delegates method <strong>willRotateToInterfaceOrientation</strong> and <strong>didRotateFromInterfaceOrientation</strong> run and handle the rotation. Inside these methods I need to know the current keyboard height, so I can position the view properly. The problem is that the method fired by the UIKeyboardWillShowNotification notification runs after the rotation was handled by the delegate methods.</p>
<p>The order the methods run is:</p>
<ol>
<li>willRotateToInterfaceOrientation</li>
<li>didRotateFromInterfaceOrientation</li>
<li>UIKeyboardWillShowNotification method</li>
</ol>
<p>In other words, the keyboard height is just read at the end, what means both methods 1 and 2 will use the old keyboard height.</p>
<p>My question is: is there a way to read the keyboard height of a visible keyboard directly instead of relying in methods fired by notifications?</p>

<p>They both return the same value, so why there are two ways to obtain header information?
Looking at the .NET sources, if found the implementation for both in HttpWebReponse:</p>
<pre><code> // retreives response header object

/// <para>
/// Gets
/// the headers associated with this response from the server.

/// </devdoc>

string headerValue = m_HttpResponseHeaders[headerName];
return ( (headerValue==null) ? String.Empty : headerValue );

<p>Only thing i can see is, that with the Headers property i can enumerate through all availiable headers. Any ideas?</p>
