Making a blacklist for an user-mode MIDI Driver - driver

EDIT
I've actually found a way to get around this, by comparing the name of the main process with text. (_T does the trick)
Now, I want _tcscmp to compare the main process name with other names in a text file (which contains blacklisted programs). How can I do that?
BOOL ProcessBlackList() {
TCHAR modulename[MAX_PATH];
GetModuleFileName(NULL, modulename, MAX_PATH);
PathStripPath(modulename);
if (_tcscmp(modulename, _T("bannedfile.exe")) != 1) {
return 0;
}
else {
return 0x2;
}
}

How do I use SimpleFileVisitor in Java to find a file name whose encoding may vary?

I'm using SimpleFileVisitor to search for a file. It works fine on Windows and Linux. However when I try using it on Unix like operating systems It doesn't work as expected. I would get errors like this:
java.nio.file.NoSuchFileException:
/File/Location/MyFolder/\u0082\u0096\u0096âĜu0099\u0081\u0097K
\u0097\u0099\u0096\u0097\u0085\u0099Ĝu0089\u0085
It looks like the obtained name is in different character encoding and maybe that is what causing the issue. It looks like in between the obtaining the name and trying to obtain the access to the file, the encoding is getting missed up. This result in calling preVisitDirectory once then visitFileFailed for every file it tries to visit. I'm not sure why the walkFileTree method is doing that. Any idea?
My using for SimpleFileVisitor code looks like this:
Files.walkFileTree(serverLocation, finder);
My SimpleFileVisitor class:
public class Finder extends SimpleFileVisitor<Path> {
private final PathMatcher matcher;
private final List<Path> matchedPaths = new ArrayList<Path>();
private String usedPattern = null;
Finder(String pattern) {
this.usedPattern = pattern;
matcher = FileSystems.getDefault().getPathMatcher("glob:" + pattern);
}
void match(Path file) { //Compare pattern against file or dir
Path name = file.getFileName();
if (name != null && matcher.matches(name))
matchedPaths.add(file);
}
// Check each file.
#Override
public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) {
match(file);
return CONTINUE;
}
// Check each directory.
#Override
public FileVisitResult preVisitDirectory(Path dir, BasicFileAttributes attrs) {
match(dir);
return CONTINUE;
}
#Override
public FileVisitResult visitFileFailed(Path file, IOException e) {
System.out.println("Issue: " + e );
return CONTINUE;
}
Try using "Charset.defaultCharset()" when you create those "file" and "dir" strings you pass around. Otherwise, you could very likely mangle the names in the process of creating those strings to pass them to your visit methods.
You might also check your default encoding on the JVM your are running, if it is out of sync with the file system you are reading, your results will be, err, unpredictable.

where in the breeze entity materialization pipeline can i set a non entity object's prototype?

this question is basically the same question I asked a few weeks ago... how to tap into mappingcontext.processAnonType... I marked the question as answered by mistake and since then have not been able to get any follow up.
Basically what I am trying to figure out is a location within the breeze pipeline that i can set a non entity object's prototype when the object is materialized from server results... when breeze processes results from the servers that are not entities, it ends up calling the method below of the helper MappingContext class... this method is as follows:
function processAnonType(mc, node) {
// node is guaranteed to be an object by this point, i.e. not a scalar
var keyFn = mc.metadataStore.namingConvention.serverPropertyNameToClient;
var result = {};
__objectForEach(node, function (key, value) {
var newKey = keyFn(key);
var nodeContext = { nodeType: "anonProp", propertyName: newKey };
visitNode(value, mc, nodeContext, result, newKey);
});
return result;
}
up above the value of "results" is what the client ends up receiving from breeze... this is a perfect place that I could do what it is i want to do just because i have access to the final object ("results") AND the node.$type property... i basically want to parse the node.$type property in order to figure out the prototype of the non entity object... unfortunately it does not appear processAnonType is an interception point within the pipeline... in the previous question i asked, i was directed to look at a custom jsonresultsadapter... i did that but i don't think it will work simply because the jsonresultsadapter does not ever appear to be in the position of changing the value of "results" (the final object returned)... so even if i implement a custom jsonresulsadapter and return new nodes, the value of "results" up above continues to be the same... can anyone please clue me in? thank you
EDIT #1: I already tried using a custom jsonresultsadapter… but this does NOT work for what I am SPECIFICALLY trying to do, UNLESS I am using a very old version of breeze (unlikely) or am missing something really obvious (more likely)... down below I have provided two snippets of breeze code that will hopefully help me explain my conclusion... the first snippet is the “visitandmerge” method of the mappingcontext… towards the bottom of that method you’ll see a call made to “jra.visitnode”… that’s great… it calls my custom jra implementation which returns a “node” property in the result such that the following line will use that node rather than the original one… so far so good… then at the end you’ll see that a call is made to “processmeta” that passes in my custom node… ok fine… but then if you look the “processmeta” code in my case the last “else” block ends up being invoked and a call is made to “processanontype”… this is where the problem is… at this point my custom node is discarded for purposes of creating/instantiating the final object returned to the client… I understand my custom node will be used to create properties for the final object but that's not what I am after... instead I need to manipulate the final object myself by setting its prototype… as I mentioned previously, if you look at the “processanontype” method it creates a new object (var result = {};) and that object is returned to the client, NOT my custom node, which is inline with what the documentation says… please see all the comments I left in the previous post... do you understand what my problem is? I am probably missing something here really obvious… can you please clue me in? thanks again

You should NOT need to modify the processAnonType method.
The parameters to the visitNode method in the jsonResultsAdapter have all of the information regarding the node being visited that you say you need. (See the link at the bottom of this post). The result from the visitNode is an object with the following properties:
entityType: you should return null for an anonymous type
nodeId and nodeRefId: ( probably not needed for an anonymous objects unless you plan to return multiple refs to the same object)
ignore: boolean - (if you want to completely ignore the node).
node: This is where you can take the incoming node ( the first parameter in the visitNode parameter list) and modify it, or return a completely new node object that represents your anonType instance. This object will be returned to the client unchanged, so you can create an new instance of your object with whatever prototype you want. If you don't set this property then the original incoming node will be used.
passThru: (avail in breeze versions > v 1.5.4) boolean - you should return true to return the node (above) intact without ANY further processing.
So your visitNode will look something like this:
visitNode: function(node, mappingContext, nodeContext) {
// 'isAnonType' is your method that determines if this is an anon type
var isAnon = isAnonType(node.$type);
if (isAnonType) {
// 'createCustomAnonNode' is your method where you create a copy of the node with whatever prototype you want.
// prototype you want.
var newNode = createCustomAnonNode(node);
return {
return { passThru: true, node: newNode };
}
} else {
// assuming that you kept track of the default JsonResultsAdapter;
return defaultAdapter.visitNode(node, mappingContext, nodeContext);
}
}

how to remove a node from linked list using recursion?

I need to remove a node from a linked list using recursion. this is the code that I have so far...
public class SortedSetNode implements Set {
protected String value;
protected SortedSetNode next;
public boolean remove(String element) {
if (value.equals(element))
{
next = next.getNext();
return true;
}
else
{
return next.remove(element);
}
}
Well, without knowing what the problem is that you are facing, you would need a clause in there to check whether the item you are removing is actually in the linked list, i.e.
if(next == null){
return false;
}
Other than that your code looks fine. What is the issue you are encountering?
If the value attribute is the value of the current node, then you'll need to delete itself when value equals element, rather than delete the next. Unless it's the value of next node.
You might need a start point, so when you compare value, you compare the next node's value with the string, and if found, do your next = next.getNext();. Of course a check of null is needed.

java.lang.IllegalStateException: trying to requery an already closed cursor android.database.sqlite.SQLiteCursor#

I've read several related posts and even posted and answer here but it seems like I was not able to solve the problem.
I have 3 Activities:
Act1 (main)
Act2
Act3
When going back and forth Act1->Act2 and Act2->Act1 I get no issues
When going Act2->Act3 I get no issues
When going Act3->Act2 I get occasional crashes with the following error: java.lang.IllegalStateException: trying to requery an already closed cursor android.database.sqlite.SQLiteCursor#.... This is a ListView cursor.
What I tried:
1. Adding stopManagingCursor(currentCursor);to the onPause() of Act2 so I stop managing the cursor when leaving Act2 to Act3
protected void onPause()
{
Log.i(getClass().getName() + ".onPause", "Hi!");
super.onPause();
saveState();
//Make sure you get rid of the cursor when leaving to another Activity
//Prevents: ...Unable to resume activity... trying to requery an already closed cursor
Cursor currentCursor = ((SimpleCursorAdapter)getListAdapter()).getCursor();
stopManagingCursor(currentCursor);
}
When returning back from Act3 to Act2 I do the following:
private void populateCompetitorsListView()
{
ListAdapter currentListAdapter = getListAdapter();
Cursor currentCursor = null;
Cursor tournamentStocksCursor = null;
if(currentListAdapter != null)
{
currentCursor = ((SimpleCursorAdapter)currentListAdapter).getCursor();
if(currentCursor != null)
{
//might be redundant, not sure
stopManagingCursor(currentCursor);
// Get all of the stocks from the database and create the item list
tournamentStocksCursor = mDbHelper.retrieveTrounamentStocks(mTournamentRowId);
((SimpleCursorAdapter)currentListAdapter).changeCursor(tournamentStocksCursor);
}
else
{
tournamentStocksCursor = mDbHelper.retrieveTrounamentStocks(mTournamentRowId);
}
}
else
{
tournamentStocksCursor = mDbHelper.retrieveTrounamentStocks(mTournamentRowId);
}
startManagingCursor(tournamentStocksCursor);
//Create an array to specify the fields we want to display in the list (only name)
String[] from = new String[] {StournamentConstants.TblStocks.COLUMN_NAME, StournamentConstants.TblTournamentsStocks.COLUMN_SCORE};
// and an array of the fields we want to bind those fields to (in this case just name)
int[] to = new int[]{R.id.competitor_name, R.id.competitor_score};
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter tournamentStocks = new SimpleCursorAdapter(this, R.layout.competitor_row, tournamentStocksCursor, from, to);
//tournamentStocks.convertToString(tournamentStocksCursor);
setListAdapter(tournamentStocks);
}
So I make sure I invalidate the cursor and use a different one. I found out that when I go Act3->Act2 the system will sometimes use the same cursor for the List View and sometimes it will have a different one.
This is hard to debug and I was never able to catch a crashing system while debugging. I suspect this has to do with the time it takes to debug (long) and the time it takes to run the app (much shorter, no pause due to breakpoints).
In Act2 I use the following Intent and expect no result:
protected void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
Intent intent = new Intent(this, ActivityCompetitorDetails.class);
intent.putExtra(StournamentConstants.App.competitorId, id);
intent.putExtra(StournamentConstants.App.tournamentId, mTournamentRowId);
startActivity(intent);
}
Moving Act1->Act2 Act2->Act1 never gives me trouble. There I use startActivityForResult(intent, ACTIVITY_EDIT); and I am not sure - could this be the source of my trouble?
I would be grateful if anyone could shed some light on this subject. I am interested in learning some more about this subject.
Thanks,D.
I call this a 2 dimensional problem: two things were responsible for this crash:
1. I used startManagingCursor(mItemCursor); where I shouldn't have.
2. I forgot to initCursorAdapter() (for autocomplete) on onResume()
//#SuppressWarnings("deprecation")
private void initCursorAdapter()
{
mItemCursor = mDbHelper.getCompetitorsCursor("");
startManagingCursor(mItemCursor); //<= this is bad!
mCursorAdapter = new CompetitorAdapter(getApplicationContext(), mItemCursor);
initItemFilter();
}
Now it seems to work fine. I hope so...
Put this it may work for you:
#Override
protected void onRestart() {
// TODO Auto-generated method stub
super.onRestart();
orderCursor.requery();
}
This also works
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
startManagingCursor(Cursor);
}

SPWeb.Fields is empty when iterating through SPWebCollection

I'm writing a command line application that checks the SPFieldCollection returned by the SPWeb.Fields property, but it's not behaving as I'd like. I have hundreds of SPWebs and it's definitely touching them all, but for all but the initial SPWeb, it's returning an empty Fields property. What am I doing wrong?
string siteUrl = "http://webroot/sitecoll";
using (SPSite siteCol = new SPSite(siteUrl))
{
using(SPWeb outerWeb = siteCol.OpenWeb())
{
foreach (SPWeb innerWeb in siteCol.AllWebs)
{
LogMessageToFile(String.Format("Checking {0}", innerWeb.Url)); //executed for each of the hundreds of innerWebs
if (innerWeb.Fields.ContainsField("Year"))
{
// Never accessed after the first time through because innerWeb.Fields is empty
}
}
}
}
SPweb.Fields live at the site collection level.
Unless you specifically create the fields at the subsite levels you will get 0 returned.
