Took me a while to figure this one out.
The reason for the error was insufficient space in the Windows System Reserved partition. I had to shrink my C drive and expand the System Reserved partition. (I used GParted from Linux, you can use a boot CD like PartedMagic or whatever method works for you).
Windows boot might break because of this. You’ll get error 0xc0000225.
You’ll have to boot from a Windows 8(.1) installation media, get to the command line and then:
select disk 0 (0 is the number of the drive)
list partition to see make sure this is the right drive and to find the system reserved partition number.
select partition 1 (change 1 to the reserved partition number)
exit to close the tool
bcdboot C:\Windows (change C to the partition where Windows in installed).
Windows should boot now. You can use EasyBCD to remove the old unbootable BCD entry.
Hope it helps.
When programming for Android, you have to take into account that your application will be killed, paused and recreated without your consent. This is because of the nature of phones which have less memory and move from one task to another without the ability to support everything at the same time.
The example I’m going to take is screen rotation. When the screen rotates, the visible activity gets recreated. How do I know that? I have two
Spinners on it, one with an adapter that changes according to the other’s selection. With each rotation I lost the current selection of the second
Spinner. I added some Toasts to the code and found that
onCreate() is being called upon orientation change. The first thing that comes to mind is to save the selection somewhere and restore it after the recreation.
There is a facility for that. Have you seen the parameter that your
protected void onCreate(Bundle savedInstanceState)
savedInstanceState is a ‘bundle’ which means a space that Android gives your application to save some info between recreations of your activities. There are also two methods you can use to put the save and restore code in:
public void onSaveInstanceState(Bundle savedInstanceState)
public void onRestoreInstanceState(Bundle savedInstanceState)
num = savedInstanceState.getInt("numberOfThings");
numnum = savedInstanceState.getInt("anotherNumber");
This didn’t help me completely because it was only then that I realized that onCreate is called for every rotation and in onCreate I initialized my UI elements to their default values. I tried putting
num = savedInstanceState.getInt("numberOfThings") in onCreate to load the previous values but got a null reference exception on the first run because
savedInstanceState is not initialized if this is the first run. The complete solution was to ditch
onRestoreInstanceState and use only
onCreate(). I set the default values in variables, and then did:
if (savedInstanceState != null)
// Load variables here and overrite the default values
The rest of the initialization stayed as it was.
So the complete solution is:
- Save the values you need in class members using
onCreate() restore the values if
savedInstanceState != null and use them for initialization
That’s all folks.
Well, at least anything that can be printed. It’s quite easy.
- Create a string stream
- “Print” the value to the stream
- Get a string from the string stream
I like to wrap it in a template function like that:
template <typename T>
string to_string(T x)
You can make the function inline, and get the argument as a reference to const if you want.
Have you got a simpler generic solution?
