  • Setting up Django on an internal server (os.environ() not working as expected?)

    - by monkut
    I'm trying to setup Django on an internal company server. (No external connection to the Internet.) Looking over the server setup documentation it appears that the "Running Django on a shared-hosting provider with Apache" method seems to be the most-likely to work in this situation. Here's the server information: Can't install mod_python no root access Server is SunOs 5.6 Python 2.5 Apache/2.0.46 I've installed Django (and flup) using the --prefix option (reading again I probably should've used --home, but at the moment it doesn't seem to matter) I've added the .htaccess file and mysite.fcgi file to my root web directory as mentioned here. When I run the mysite.fcgi script from the server I get my expected output (the correct site HTML output). But, it won't when trying to access it from a browser. It seems that it may be a problem with the PYTHONPATH setting since I'm using the prefix option. I've noticed that if I run mysite.fcgi from the command-line without setting the PYTHONPATH enviornment variable it throws the following error: prompt$ python2.5 mysite.fcgi ERROR: No module named flup Unable to load the flup package. In order to run django as a FastCGI application, you will need to get flup from http://www.saddi.com/software/flup/ If you've already installed flup, then make sure you have it in your PYTHONPATH. I've added sys.path.append(prefixpath) and os.environ['PYTHONPATH'] = prefixpath to mysite.fcgi, but if I set the enviornment variable to be empty on the command-line then run mysite.fcgi, I still get the above error. Here are some command-line results: >>> os.environ['PYTHONPATH'] = 'Null' >>> >>> os.system('echo $PYTHONPATH') Null >>> os.environ['PYTHONPATH'] = '/prefix/path' >>> >>> os.system('echo $PYTHONPATH') /prefix/path >>> exit() prompt$ echo $PYTHONPATH Null It looks like Python is setting the variable OK, but the variable is only applicable inside of the script. Flup appears to be distributed as an .egg file, and my guess is that the egg implementation doesn't take into account variables added by os.environ['key'] = value (?) at least when installing via the --prefix option. I'm not that familiar with .pth files, but it seems that the easy-install.pth file is the one that points to flup: import sys; sys.__plen = len(sys.path) ./setuptools-0.6c6-py2.5.egg ./flup-1.0.1-py2.5.egg import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sy s.path[p:p]=new; sys.__egginsert = p+len(new) It looks like it's doing something funky, anyway to edit this or add something to my code so it will find flup?

    It doesnt find nor replaces the strings.. may be wrong regex? // ==UserScript== // @name CurConvertor // @namespace CurConvertor // @description noam smadja // @include http://www.zavvi.com/* // ==/UserScript== textNodes = document.evaluate( "//text()", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); var searchRE = new RegExp('\d\d.\d\d','gi'); var replace = searchRE*5.67; for (var i=0;i<textNodes.snapshotLength;i++) { var node = textNodes.snapshotItem(i); node.data = node.data.replace(searchRE, replace); i wrote this, but its not doing a think. even when i change the string in the regex to a string in the webpage it still does nothing.. what am i missing? :)

  • Strange PHP reference bug

    - by Roland Soós
    Hello, I have a really strange bug with my PHP code. I have a recursive code which build up a menu tree with object and one of my customers server can't make it work. Contructor: function Menu(&$menus, &$keys , &$parent, &$menu){ ... if($keys === NULL){ $keys = array_keys($menus); } ... for($x = 0; $x < count($keys); $x++) { var_dump($keys); $menu = $menus[$keys[$x]]; var_dump($keys); if($this->id == $menu->pid){ $keys[$x] = NULL; $this->submenus[] = new Menu($menus, $keys, $this, $menu); } } First var_dump give me back the array, the second give back the first element of $menus. Do you have any idea what causes this? PHP version 5.2.3

  • DbDataReader with DbTransactions

    - by Gustavo Paulillo
    Its the wrong way or lack of performance, using DbDataReader combinated with DbTransactions? An example of code: public DbDataReader ExecuteReader() { try { if (this._baseConnection.State == ConnectionState.Closed) this._baseConnection.Open(); if (this._baseCommand.Transaction != null) return this._baseCommand.ExecuteReader(); return this._baseCommand.ExecuteReader(CommandBehavior.CloseConnection); } catch (Exception excp) { if (this._baseCommand.Transaction != null) this._baseCommand.Transaction.Rollback(); this._baseCommand.CommandText = string.Empty; this._baseConnection.Close(); throw new Exception(excp.Message); } } Some methods call this operation. Sometimes openning a DbTransaction. Its using DbConnection and DbCommand. The real problem, is in production enviroment (like 5,000 access/day) the ADO operations start throwing exceptions

  • SQL UPDATE order of evaluation

    - by pilcrow
    What is the order of evaluation in the following query: UPDATE tbl SET q = q + 1, p = q; That is, will "tbl"."p" be set to q or q + 1? Is order of evaluation here governed by SQL standard? Thanks. UPDATE After considering Migs' answer, I ran some tests on all DBs I could find. While I don't know what the standard says, implementations vary. Given CREATE TABLE tbl (p INT NOT NULL, q INT NOT NULL); INSERT INTO tbl VALUES (1, 5); -- p := 1, q := 5 UPDATE tbl SET q = q + 1, p = q; I found the values of "p" and "q" were: database p q -----------------+---+--- Firebird 2.1.3 | 6 | 6 InterBase 2009 | 5 | 6 MySQL 5.0.77 | 6 | 6 Oracle XE (10g) | 5 | 6 PostgreSQL 8.4.2 | 5 | 6

  • How to write this Linq SQL as a Dynamic Query (using strings)?

    - by Dr. Zim
    Skip to the "specific question" as needed. Some background: The scenario: I have a set of products with a "drill down" filter (Query Object) populated with DDLs. Each progressive DDL selection will further limit the product list as well as what options are left for the DDLs. For example, selecting a hammer out of tools limits the Product Sizes to only show hammer sizes. Current setup: I created a query object, sent it to a repository, and fed each option to a SQL "table valued function" where null values represent "get all products". I consider this a good effort, but far from DDD acceptable. I want to avoid any "programming" in SQL, hopefully doing everything with a repository. Comments on this topic would be appreciated. Specific question: How would I rewrite this query as a Dynamic Query? A link to something like 101 Linq Examples would be fantastic, but with a Dynamic Query scope. I really want to pass to this method the field in quotes "" for which I want a list of options and how many products have that option. from p in db.Products group p by p.ProductSize into g select new Category { PropertyType = g.Key, Count = g.Count() } Each DDL option will have "The selection (21)" where the (21) is the quantity of products that have that attribute. Upon selecting an option, all other remaining DDLs will update with the remaining options and counts. Edit: Additional notes: .OrderBy("it.City") // "it" refers to the entire record .GroupBy("City", "new(City)") // This produces a unique list of City .Select("it.Count()") //This gives a list of counts... getting closer .Select("key") // Selects a list of unique City .Select("new (key, count() as string)") // +1 to me LOL. key is a row of group .GroupBy("new (City, Manufacturer)", "City") // New = list of fields to group by .GroupBy("City", "new (Manufacturer, Size)") // Second parameter is a projection Product .Where("ProductType == @0", "Maps") .GroupBy("new(City)", "new ( null as string)")// Projection not available later? .Select("new (key.City, it.count() as string)")// GroupBy new makes key an object Product .Where("ProductType == @0", "Maps") .GroupBy("new(City)", "new ( null as string)")// Projection not available later? .Select("new (key.City, it as object)")// the it object is the result of GroupBy var a = Product .Where("ProductType == @0", "Maps") .GroupBy("@0", "it", "City") // This fails to group Product at all .Select("new ( Key, it as Product )"); // "it" is property cast though What I have learned so far is LinqPad is fantastic, but still looking for an answer. Eventually, completely random research like this will prevail I guess. LOL. Edit:

  • Accessing the same service more than twice in the nick of time

    - by PointedC
    I have an application that will access interface service A which is to run from windows startup. This service is used by program B and my application functions on B's presence after getting a pointer to A. The scenario is translated as follows, public interface A{} ///my program public class MyProgram { public MyProgram() { ProgramB.DoA(); } public A GetA(){} } public class ProgramB { void DoA(){} } The translated source is not true, but that seems to be what I am looking for. In order to eliminate the overhead of allocating and realocating dynamic accesses to the same service used by other processes, would you please provide an actual solution to the problem ?(I am all out of any idea now)

  • How to resolve this very heavy query that slows down the application?

    - by Juan Paredes
    Hi, We have a web application running in a production enviroment and at some point the client complained about how slow the application got. When we checked what was going on with the application and the database we discover this "precious" query that was being executed by several users at the same time (thus inflicting a extremely high load on the database server): SELECT NULL AS table_cat, o.owner AS table_schem, o.object_name AS table_name, o.object_type AS table_type, NULL AS remarks FROM all_objects o WHERE o.owner LIKE :1 ESCAPE :"SYS_B_0" AND o.object_name LIKE :2 ESCAPE :"SYS_B_1" AND o.object_type IN(:"SYS_B_2", :"SYS_B_3") ORDER BY table_type, table_schem, table_name Our application does not execute this query, I believe it is an Hibernate internal query. I've found little information on why Hibernate does this extremely heavy query, so any help is very much appreciated! The production enviroment information: Red Hat Enterprise Linux 5.3 (Tikanga), JDK 1.5, web container OC4J (whitin Oracle Application Server), Oracle Database 10g Release 10.0.0.1, JDBC Driver for JDK 1.2 and 1.3, Hibernate version 3.2.6.ga. Thank you.

  • Subclassing a window from a thread in c#

    - by user258651
    I'm creating a thread that looks for a window. When it finds the window, it overrides its windowproc, and handles WM_COMMAND and WM_CLOSE. Here's the code that looks for the window and subclasses it: public void DetectFileDialogProc() { Window fileDialog = null; // try to find the dialog twice, with a delay of 500 ms each time for (int attempts = 0; fileDialog == null && attempts < 2; attempts++) { // FindDialogs enumerates all windows of class #32770 via an EnumWindowProc foreach (Window wnd in FindDialogs(500)) { IntPtr parent = NativeMethods.User32.GetParent(wnd.Handle); if (parent != IntPtr.Zero) { // we're looking for a dialog whose parent is a dialog as well Window parentWindow = new Window(parent); if (parentWindow.ClassName == NativeMethods.SystemWindowClasses.Dialog) { fileDialog = wnd; break; } } } } // if we found the dialog if (fileDialog != null) { OldWinProc = NativeMethods.User32.GetWindowLong(fileDialog.Handle, NativeMethods.GWL_WNDPROC); NativeMethods.User32.SetWindowLong(fileDialog.Handle, NativeMethods.GWL_WNDPROC, Marshal.GetFunctionPointerForDelegate(new WindowProc(WndProc)).ToInt32()); } } And the windowproc: public IntPtr WndProc(IntPtr hWnd, uint msg, IntPtr wParam, IntPtr lParam) { lock (this) { if (!handled) { if (msg == NativeMethods.WM_COMMAND || msg == NativeMethods.WM_CLOSE) { // adding to a list. i never access the window via the hwnd from this list, i just treat it as a number _addDescriptor(hWnd); handled = true; } } } return NativeMethods.User32.CallWindowProc(OldWinProc, hWnd, msg, wParam, lParam); } This all works well under normal conditions. But I am seeing two instances of bad behavior in order of badness: If I do not close the dialog within a minute or so, the app crashes. Is this because the thread is getting garbage collected? This would kind of make sense, as far as GC can tell the thread is done? If this is the case, (and I don't know that it is), how can I make the thread stay around as long as the dialog is around? If I immediately close the dialog with the 'X' button (WM_CLOSE) the app crashes. I believe its crashing in the windowproc, but I can't get a breakpoint in there. I'm getting an AccessViolationException, The exception says "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." Its a race condition, but of what I don't know. FYI, I had been reseting the old windowproc once I processed the commands, but that was crashing even more often! Any ideas on how I can solve these issues?

  • Trying to Add Insert Row to Footer in GridView ASP.net

  • Postgresql 8.4 reading OID style BLOBs with Hibernate

    - by peter
    I am getting this weird case when querying Postgres 8.4 for some records with Blobs (of type OIDs) with Hibernate. The query does return all right but when my code wants to read the content of the BLOB with the simple code below, it gets 0 bytes back public static byte[] readBlob(Blob blob) throws Exception { InputStream is = null; try { is = blob.getBinaryStream(); return org.apache.commons.io.IOUtils.toByteArray(is); } finally { if (is != null) try { is.close(); } catch(Exception e) {} } } Funny think is that I am getting this behavior only since I've started adding more then one such records to the table. The underlying JDBC library is type 3 (postgresq 8.4-701). Can someone give me a hint as to how to solve this issue? Thanks Peter

  • Android - How to scan Access Points and select strongest signal?

    - by Donal Rafferty
    I am currently trying to write a class in Android that will Scan for access points, calculate which access point has the best signal and then connect to that access point. So the application will be able to scan on the move and attach to new access points on the go. I have the scanning and calculation of the best signal working. But when it comes to attaching to the best access point I am having trouble. It appears that enableNetwork(netid, othersTrueFalse) is the only method for attaching to an Access point but this causes problems as from my Scan Results I am not able to get the id of the access point with the strongest signal. This is my code: public void doWifiScan(){ scanTask = new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { sResults = wifiManager.scan(getBaseContext()); if(sResults!=null) Log.d("TIMER", "sResults count" + sResults.size()); ScanResult scan = wifiManager.calculateBestAP(sResults); wifiManager.addNewAccessPoint(scan); } }); }}; t.schedule(scanTask, 3000, 30000); } public ScanResult calculateBestAP(List<ScanResult> sResults){ ScanResult bestSignal = null; for (ScanResult result : sResults) { if (bestSignal == null || WifiManager.compareSignalLevel(bestSignal.level, result.level) < 0) bestSignal = result; } String message = String.format("%s networks found. %s is the strongest. %s is the bsid", sResults.size(), bestSignal.SSID, bestSignal.BSSID); Log.d("sResult", message); return bestSignal; } public void addNewAccessPoint(ScanResult scanResult){ WifiConfiguration wc = new WifiConfiguration(); wc.SSID = '\"' + scanResult.SSID + '\"'; //wc.preSharedKey = "\"password\""; wc.hiddenSSID = true; wc.status = WifiConfiguration.Status.ENABLED; wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK); wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP); wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP); wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN); int res = mainWifi.addNetwork(wc); Log.d("WifiPreference", "add Network returned " + res ); boolean b = mainWifi.enableNetwork(res, false); Log.d("WifiPreference", "enableNetwork returned " + b ); } When I try to use addNewAccessPoint(ScanResult scanResult) it just adds another AP to the list in the settings application with the same name as the one with the best signal, so I end up with loads of duplicates and not actually attaching to them. Can anyone point me in the direction of a better solution?

  • Making an Ajax request to a page method in ASP.NET MVC 2

    - by JLago
    I'm trying to call a page method belonging to a MVC Controller from another site, by means of: $.ajax({ type: "GET", url: "http://localhost:54953/Home/ola", data: "", contentType: "application/json; charset=utf-8", dataType: "json", success: function(data) { console.log(data.Name); } }); the method code is as follows, really simple, just to test: public ActionResult ola() { return Json(new ActionInfo() { Name = "ola" },JsonRequestBehavior.AllowGet); } I've seen this aproach being suggested here, and I actually like it a lot, should it work... When I run this, firebug gets a 200 OK, but the data received is null. I've tried a lot of different approaches, like having the data in text (wish grants me "(an empty string)" instead of just "null") or returning string in the server method... Can you tell me what am I doing wrong? Thank you in advance, João

    I use two computers, a Linux one for coding and building and a Windows one which has the programming application to load the built program onto the hardware. Both computers have access to a network drive which I use to pass the files from Linux to Windows. My problem is, that every time I build I have to copy the files from where the are created to the network drive. How can I make some sort of file in the network drive on Ubuntu that always mirrors the file which is built in the different location, like a pointer? Thanks!

  • Pass data from one form to another on a seperate page

    - by Micanio
    I am building a price/distance calculator with Google Maps API and am trying to pass the info from the calculator to a booking form on a separate page. My first form has 2 submit buttons - one to make the calculation, and one to submit the relevant data to the booking form. I'm stuck trying to make the 2nd button work. Once the API calculation has been made, I get 4 values - From, To, Cost, Distance. I am trying to pass the From, To and Cost values into my booking form by clicking the second button. But I can;t seem to get it to work. I've tried POST and GET but I think I may have been doing something wrong with both. Any help is appreciated.

  • Racket list in struct

    - by Tim
    I just started programming with Racket and now I have the following problem. I have a struct with a list and I have to add up all prices in the list. (define-struct item (name category price)) (define some-items (list (make-item "Book1" 'Book 40.97) (make-item "Book2" 'Book 5.99) (make-item "Book3" 'Book 20.60) (make-item "Item" 'KitchenAccessory 2669.90))) I know that I can return the price with: (item-price (first some-items)) or (item-price (car some-items)). The problem is, that I dont know how I can add up all Items prices with this. Answer to Óscar López: May i filled the blanks not correctly, but Racket mark the code black when I press start and don't return anything. (define (add-prices items) (if (null? items) (+ 0 items) ; Here I don't really know what to write for a 0. ; I tried differnt thnigs like null and this version. (+ (item-price (first some-items)) (add-prices (item-price (rest some-items))))))

  • Dataset field DBNull -> int?

    - by BobClegg
    SQLServer int field. Value sometimes null. DataAdapter fills dataset OK and can display data in DatagridView OK. When trying to retrieve the data programmatically from the dataset the Dataset field retrieval code throws a StronglyTypedException error. [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] public int curr_reading { get { try { return ((int)(this[this.tableHistory.curr_readingColumn])); } catch (global::System.InvalidCastException e) { throw new global::System.Data.StrongTypingException("The value for column \'curr_reading\' in table \'History\' is DBNull.", e); } Got past this by checking for DBNull in the get accessor and returning null but... When the dataset structure is modified (Still developing) my changes (unsurprisingly) are gone. What is the best way to handle this situation? It seems I am stuck with dealing with it at the dataset level. Is there some sort of attribute that can tell the auto code generator to leave the changes in place?

  • Setting a value through reflection is not working.

    - by Scott Chamberlain
    I am trying to set a value through reflection. I created this little test program struct headerIndexes { public int AccountNum{ get; set; } public int other { get; set; } public int items { get; set; } } static void Main(string[] args) { headerIndexes headers = new headerIndexes(); headers.AccountNum = 1; Console.WriteLine("Old val: {0}", headers.AccountNum); foreach (var s in headers.GetType().GetProperties()) { if (s.Name == "AccountNum") s.SetValue(headers, 99, null); } Console.WriteLine("New val: {0}", headers.AccountNum); Console.ReadKey(); } Steping thorugh the program i see it correctly does the command s.SetValue(headers, 99, null); however the value of headers.AccountNum stays at 1 when setValue is run. Am I missing a obvious step?

  • How do I create a foreign key in SQL Server?

    - by mmattax
    I have never "hand coded" creation code for SQL Server and foreign key deceleration is seemingly different from SQL Server and Postgres...here is my sql so far: drop table exams; drop table question_bank; drop table anwser_bank; create table exams ( exam_id uniqueidentifier primary key, exam_name varchar(50), ); create table question_bank ( question_id uniqueidentifier primary key, question_exam_id uniqueidentifier not null, question_text varchar(1024) not null, question_point_value decimal, constraint question_exam_id foreign key references exams(exam_id) ); create table anwser_bank ( anwser_id uniqueidentifier primary key, anwser_question_id uniqueidentifier, anwser_text varchar(1024), anwser_is_correct bit ); when I run the query I get this error: Msg 8139, Level 16, State 0, Line 9 Number of referencing columns in foreign key differs from number of referenced columns, table 'question_bank'. Can you spot the error? thanks.

  • I need help with Widget and PendingIntents

    - by YaW
    Hi, I've asked here a question about Task Killers and widgets stop working (SO Question) but now, I have reports of user that they don't use any Task Killer and the widgets didn't work after a while. I have a Nexus One and I don't have this problem. I don't know if this is a problem of memory or something. Based on the API: A PendingIntent itself is simply a reference to a token maintained by the system describing the original data used to retrieve it. This means that, even if its owning application's process is killed, the PendingIntent itself will remain usable from other processes that have been given it. So, I don't know why widget stop working, if Android doesn't kill the PendingIntent by itself, what's the problem? This is my manifest code: <receiver android:name=".widget.InstantWidget" android:label="@string/app_name"> <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE" /> </intent-filter> <meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_provider" /> </receiver> And the widget code: public class InstantWidget extends AppWidgetProvider { public static ArrayList<Integer> alWidgetsId = new ArrayList<Integer>(); private static final String PREFS_NAME = "com.cremagames.instant.InstantWidget"; private static final String PREF_PREFIX_NOM = "nom_"; private static final String PREF_PREFIX_RAW = "raw_"; /** * Esto se llama cuando se crea el widget. Metemos en las preferencias los valores de nombre y raw para tenerlos en proximos reboot. * @param context * @param appWidgetManager * @param appWidgetId * @param nombreSound * @param rawSound */ static void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId, String nombreSound, int rawSound){ //Guardamos en las prefs los valores SharedPreferences.Editor prefs = context.getSharedPreferences(PREFS_NAME, 0).edit(); prefs.putString(PREF_PREFIX_NOM + appWidgetId, nombreSound); prefs.putInt(PREF_PREFIX_RAW + appWidgetId, rawSound); prefs.commit(); //Actualizamos la interfaz updateWidgetGrafico(context, appWidgetManager, appWidgetId, nombreSound, rawSound); } /** * Actualiza la interfaz gráfica del widget (pone el nombre y crea el intent con el raw) * @param context * @param appWidgetManager * @param appWidgetId * @param nombreSound * @param rawSound */ private static void updateWidgetGrafico(Context context, AppWidgetManager appWidgetManager, int appWidgetId, String nombreSound, int rawSound){ RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget); //Nombre del Button remoteViews.setTextViewText(R.id.tvWidget, nombreSound); //Creamos el PendingIntent para el onclik del boton Intent active = new Intent(context, InstantWidget.class); active.setAction(String.valueOf(appWidgetId)); active.putExtra("sonido", rawSound); PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0); actionPendingIntent.cancel(); actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0); remoteViews.setOnClickPendingIntent(R.id.btWidget, actionPendingIntent); appWidgetManager.updateAppWidget(appWidgetId, remoteViews); } public void onReceive(Context context, Intent intent) { final String action = intent.getAction(); //Esto se usa en la 1.5 para que se borre bien el widget if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) { final int appWidgetId = intent.getExtras().getInt( AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) { this.onDeleted(context, new int[] { appWidgetId }); } } else { //Listener de los botones for(int i=0; i<alWidgetsId.size(); i++){ if (intent.getAction().equals(String.valueOf(alWidgetsId.get(i)))) { int sonidoRaw = 0; try { sonidoRaw = intent.getIntExtra("sonido", 0); } catch (NullPointerException e) { } MediaPlayer mp = MediaPlayer.create(context, sonidoRaw); mp.start(); mp.setOnCompletionListener(completionListener); } } super.onReceive(context, intent); } } /** Al borrar el widget, borramos también las preferencias **/ public void onDeleted(Context context, int[] appWidgetIds) { for(int i=0; i<appWidgetIds.length; i++){ //Recogemos las preferencias SharedPreferences.Editor prefs = context.getSharedPreferences(PREFS_NAME, 0).edit(); prefs.remove(PREF_PREFIX_NOM + appWidgetIds[i]); prefs.remove(PREF_PREFIX_RAW + appWidgetIds[i]); prefs.commit(); } super.onDeleted(context, appWidgetIds); } /**Este método se llama cada vez que se refresca un widget.

I have the possibility to put differents widgets on the desktop, that's why I use the widgetId as the "unique id" for the PendingIntent. Any ideas please? The 70% of the functionality of my app is the widgets, and it isn't working for some users :( Thanks in advance and sorry for my English.

  • Terminate long running thread in thread pool that was created using QueueUserWorkItem(win 32/nt5).

    - by Jake
    I am programming in a win32 nt5 environment. I have a function that is going to be called many times. Each call is atomic. I would like to use QueueUserWorkItem to take advantage of multicore processors. The problem I am having is I only want to give the function 3 seconds to complete. If it has not completed in 3 seconds I want to terminate the thread. Currently I am doing something like this: HANDLE newThreadFuncCall= CreateThread(NULL,0,funcCall,&func_params,0,NULL); DWORD result = WaitForSingleObject(newThreadFuncCall, 3000); if(result == WAIT_TIMEOUT) { TerminateThread(newThreadFuncCall,WAIT_TIMEOUT); } I just spawn a single thread and wait for 3 seconds or it to complete. Is there anyway to do something similar to but using QueueUserWorkItem to queue up the work? Thanks!

  • How to run PowerShell scripts via automation without running into Host issues

    - by Scott Weinstein
    I'm looking to run some powershell scripts via automation. Something like: IList errors; Collection<PSObject> res = null; using (RunspaceInvoke rsi = new RunspaceInvoke()) { try { res = rsi.Invoke(commandline, null, out errors); } catch (Exception ex) { LastErrorMessage = ex.ToString(); Debug.WriteLine(LastErrorMessage); return 1; } } the problem I'm facing is that if my script uses cmdlets such as write-host the above throws an System.Management.Automation.CmdletInvocationException - Cannot invoke this function because the current host does not implement it. What are some good options for getting around this problem?
