Hi
Is there a permission to allow one app to read the (private) data/data//files/... files of another application? If not, how do backup programs like MyBackup work?

Hello.
I develop application with Java.
I need to store some initial configuration data in some kind of file.
I want my app to be able to read this data, but I don't want user to do so.
Example : application loads IP from encrypted file. User sees like "dsda@#21da@" so he won't bother doing anything :)
How should I do such a thing?
Thanx!

How can I plot (a 3D plot) a matrix in Gnuplot having such data structure. I cannot find a way to use the first row and column as a x and y ticks (or to ignore them)
,5,6,7,8
1,-6.20,-6.35,-6.59,-6.02
2,-6.39,-6.52,-6.31,-6.00
3,-6.36,-6.48,-6.15,-5.90
4,-5.79,-5.91,-5.87,-5.46
Is the splot 'data.csv' matrix the correct parameter to use ?
Whats a better way to store textual data, such as comments, user profile fields that require them to type something in, etc? Store the escaped data right away (using htmlspecialchars in php for example), or put it thru the same function before its echoed out?

Hi
In my app I use a ListView to display data from the database. The data changes sometimes, for example when the user applies new filters or changes the sorting method. I use AsyncTask to get the databsase cursor that points to the new data set because sometimes data needs to be loaded from the net which can take some time.
What I do now looks something like this:
private class updateTask extends AsyncTask<Void, Void, Void> {
/*
* runs on the UI thread before doInBackground
*/
@Override
protected void onPreExecute(){
// prepare some stuff...
}
/*
* runs in a separate thread
* used for time-consuming loading operation
*/
@Override
protected Void doInBackground() {
//get new database cursor
mCursor = mDbAdapter.getCursor();
return null;
}
/*
* runs on the UI thread after doInBackground
*/
@Override
protected void onPostExecute(Void result){
if(mCursor!=null){
MyActivity.this.startManagingCursor(mCursor);
mCursorAdapter = new MyCustomCursorAdapter(MyActivity.this, mCursor);
mListView.setAdapter(mCursorAdapter);
}
}
}
This works so far but I realize that creating a new CursorAdapter and calling setAdapter on my ListView each time isn't the correct way to do it.
Also, after setAdapter the scroll position of the list is set back to the top. I found this post which describes how to do it properly. So now I want to do something like this:
onCreate(){
// ...
// create the CursorAdapter using null as the initial cursor
MyCustomCursorAdapter cursorAdapter = new MyCustomCursorAdapter(this, null);
mListView.setAdapter(cursorAdapter);
// ...
}
private class updateTask extends AsyncTask<Void, Void, Void> {
/*
* runs on the UI thread before doInBackground
*/
@Override
protected void onPreExecute(){
// prepare some stuff...
}
/*
* runs in a separate thread
* used for time-consuming loading operation
*/
@Override
protected Void doInBackground() {
//get new database cursor
mCursor = mDbAdapter.getCursor();
return null;
}
/*
* runs on the UI thread after doInBackground
*/
@Override
protected void onPostExecute(Void result){
// this returns null!
MyCustomCursorAdapter cursorAdapter = (MyCustomCursorAdapter)mListView.getAdapter();
Cursor oldCursor = cursorAdapter.getCursor();
if(oldCursor!=null){
MyActivity.this.stopManagingCursor(oldCursor);
oldCursor.close();
}
if(mCursor!=null){
MyActivity.this.startManagingCursor(mCursor);
cursorAdapter.changeCursor(mCursor);
}
}
}
This however doesn't work for me because
(MyCustomCursorAdapter)mListView.getAdapter();
always returns null.
Why does this happen? What am I doing wrong?
Edit:
Some additional information: my adapter implements SectionIndexer. I don't really think that this has anything to do with my problem but it has caused me some troubles before so I thought I'd mention it.
I'm trying to export data to a csv file. It should contain a header (from datastack) and restacked arrays with my data (from datastack). One line in datastack has the same length as dataset. The code below works but it removes parts of the first line from datastack. Any ideas why that could be?
s = ','.join(itertools.chain(dataset)) + '\n'
newfile = 'export.csv'
f = open(newfile,'w')
f.write(s)
numpy.savetxt(newfile, (numpy.transpose(datastack)), delimiter=', ')
f.close()

I'm building an iPhone app which needs a peice of meta data from a user's Google Spreadsheet. Unfortunately the meta data I need is not exposed by the API, so I will need to scrape it from the document's HTML source (it would not be present in any of the exported variants).
Is there anyway to include authentication parameters in a call such as:
http://spreadsheets.google.com/ccc?key=abc123&username=...&password=...

I have an Excel Spreadsheet that contains all my data that I need to put into an SQL Server database. I am fairly new o ASP.NET and have never had to export from Excel to SQL Server before.
My Excel spreadsheets looks like this
Trade Heading - ArtID - BusinessName - AdStyleCode - Address - Suburb
In SQL Server I have created a table named "Listings" which is in this format
intListingID - intCategoryID - BusinessName - ArtID - intAdCode -Address - Suburb
What would be the best way to export the data from Excel and then import it into SQLServer 2005.
Thanks...
Hi,
I have several files about 15k each of CSV data I need to import into SQL Server 2005.
What would be the simplest way to import the csv data into sql server? Ideally, the tool or method would create the table as well, since there are about 180 fields in it, this would simplify things.
I am trying to use jQuery AJAX. What my requirement is, i wish to load user names from DB in dataset, convert it to JSON format and store it in memory or using jQuery data for use while a user is browsing my site, i.e for a session. This way I can use autocomplete or my own code to display data to user.
Can anyone help me design such a scenario?
I've read like 10 or so "tutorials", and they all involve the same thing:
Pull a count of the data set
Pull the relevant data set (LIMIT, OFFSET)
IE:
SELECT COUNT(*)
FROM table
WHERE something = ?
SELECT *
FROM table
WHERE something =?
LIMIT ? offset ?`
Two very similar queries, no? There has to be a better way to do this, my dataset is 600,000+ rows and already sluggish (results are determined by over 30 where clauses, and vary from user to user, but are properly indexed of course).
I've read similar questions here but I'm still a little confused.
MyCollection extends ArrayList<MyClass>
MyClass implements Data
yet this gives me the "cannot convert from ArrayList to MyCollection"
MyCollection mycollection = somehandler.getCollection();
where getCollection looks like this
public ArrayList<Data> getCollection()
So my assumptions are obviously wrong. How can I make this work like I would like it to
I have an application that I want to represent a users session (just small pieces of data here and there) within a GUID. Its a 16 HEX characters (so 16^16 possible values) string and I want to 'encode' some data within that GUID.
How can I achieve this? I am really after any ideas and implementations here, Ive not yet decided on the best mechanism for it yet.
I would also like encryption to be involved if possible...
Thanks a lot
