I mean the .NET way. Does anybody know how to do it? :) Thanks

  • JSP Problem ussing implicit object (session) in a function

    - by user234666
    Can the object of type HttpSession called session be accessed from a function? In a simple jsp page I have a function(see below) defined in the header of the page, and set to an onclick handle of for a button. When I press this button, I'll never see the second alert message. If I do something in the body of the page (like Session ID: <%= session.getId() % ) I have no trouble accessing it. What newbie mistake am I making? function doTest() { alert('Preforming test 122333232'); String sessionId = session.getId(); alert('After access'); if(sessionId == null) { alert('session id is null?'); } Thanks

  • SQL Server 2000 - Filter by String Length

    - by user208662
    Hello, I have a database on a SQL Server 2000 server. This database has a table called "Person" that has a field call "FullName" that is a VARCHAR(100). I am trying to write a query that will allow me to get all records that have a name. Records that do not have a name have a FullName value of either null or an empty string. How do I get all of the Person records have a FullName? In other words, I want to ignore the records that do not have a FullName. Currently I am trying the following: SELECT * FROM Person p WHERE p.FullName IS NOT NULL AND LEN(p.FullName) > 0 Thank you

  • Split string in C every white space

    - by redsolja
    I want to write a program in C that displays each word of a whole sentence (taken as input) at a seperate line. This is what i have done so far: void manipulate(char *buffer); int get_words(char *buffer); int main(){ char buff[100]; printf("sizeof %d\nstrlen %d\n", sizeof(buff), strlen(buff)); // Debugging reasons bzero(buff, sizeof(buff)); printf("Give me the text:\n"); fgets(buff, sizeof(buff), stdin); manipulate(buff); return 0; } int get_words(char *buffer){ // Function that gets the word count, by counting the spaces. int count; int wordcount = 0; char ch; for (count = 0; count < strlen(buffer); count ++){ ch = buffer[count]; if((isblank(ch)) || (buffer[count] == '\0')){ // if the character is blank, or null byte add 1 to the wordcounter wordcount += 1; } } printf("%d\n\n", wordcount); return wordcount; } void manipulate(char *buffer){ int words = get_words(buffer); char *newbuff[words]; char *ptr; int count = 0; int count2 = 0; char ch = '\n'; ptr = buffer; bzero(newbuff, sizeof(newbuff)); for (count = 0; count < 100; count ++){ ch = buffer[count]; if (isblank(ch) || buffer[count] == '\0'){ buffer[count] = '\0'; if((newbuff[count2] = (char *)malloc(strlen(buffer))) == NULL) { printf("MALLOC ERROR!\n"); exit(-1); } strcpy(newbuff[count2], ptr); printf("\n%s\n",newbuff[count2]); ptr = &buffer[count + 1]; count2 ++; } } } Although the output is what i want, i have really many black spaces after the final word displayed, and the malloc() returns NULL so the MALLOC ERROR! is displayed in the end. I can understand that there is a mistake at my malloc() implementation but i do not know what it is. Is there another more elegant - generally better way to do it? Thanks in advance.

  • json data not rendered in backbone view

    - by user2535706
    I have been trying to render the json data to the view by calling the rest api and the code is as follows: var Profile = Backbone.Model.extend({ dataType:'jsonp', defaults: { intuitId: null, email: null, type: null }, }); var ProfileList = Backbone.Collection.extend({ model: Profile, url: '/v1/entities/6414256167329108895' }); var ProfileView = Backbone.View.extend({ el: "#profiles", template: _.template($('#profileTemplate').html()), render: function() { _.each(this.model.models, function(profile) { var profileTemplate = this.template(this.model.toJSON()); $(this.el).append(tprofileTemplate); }, this); return this; } }); var profiles = new ProfileList(); var profilesView = new ProfileView({model: profiles}); profiles.fetch(); profilesView.render(); and the html file is as follows: <!DOCTYPE html> <html> <head> <title>SPA Example</title> <!-- <link rel="stylesheet" type="text/css" href="src/css/reset.css" /> <link rel="stylesheet" type="text/css" href="src/css/harmony_compiled.css" /> --> </head> <body class="harmony"> <header> <div class="title">SPA Example</div> </header> <div id="profiles"></div> <script id="profileTemplate" type="text/template"> <div class="profile"> <div class="info"> <div class="intuitId"> <%= intuitId %> </div> <div class="email"> <%= email %> </div> <div class="type"> <%= type %> </div> </div> </div> </script> </body> </html> This gives me an error and the render function isn't invoking properly and the render function is called even before the REST API returns the JSON response. Could anyone please help me to figure out where I went wrong. Any help is highly appreciated Thank you

  • Getting ready for learn html5

    - by vtortola
    Hi, I'm a desktop application developer, and I plan learning html5, but as it's not released, there is no (almost) published books and no too much infomation from beginners on the web... I fell I should start with html4 and the current web development skills. I think, I should start with html4, css and javascript... but there are so many technologies related that I get lost :D So, what current technologies will be sill used when html5 be released? I mean, what about "jquery" and "ajax"? I know they are javascript under the hood, but will they still make sense in the future? What would you recommend me considering that I have just a little bit of html knowlegde, almost null CSS and completely null in javascript? Thanks in advance.

  • T-SQL Getting duplicate rows returned

    - by cBlaine
    The following code section is returning multiple columns for a few records. SELECT a.ClientID,ltrim(rtrim(c.FirstName)) + ' ' + case when c.MiddleName <> '' then ltrim(rtrim(c.MiddleName)) + '. ' else '' end + ltrim(rtrim(c.LastName)) as ClientName, a.MISCode, b.Address, b.City, dbo.ClientGetEnrolledPrograms(CONVERT(int,a.ClientID)) as Abbreviation FROM ClientDetail a JOIN Address b on(a.PersonID = b.PersonID) JOIN Person c on(a.PersonID = c.PersonID) LEFT JOIN ProgramEnrollments d on(d.ClientID = a.ClientID and d.Status = 'Enrolled' and d.HistoricalPKID is null) LEFT JOIN Program e on(d.ProgramID = e.ProgramID and e.HistoricalPKID is null) WHERE a.MichiganWorksData=1 I've isolated the issue to the ProgramEnrollments table. This table holds one-to-many relationships where each ClientID can be enrolled in many programs. So for each program a client is enrolled in, there is a record in the table. The final result set is therefore returning a row for each row in the ProgramEnrollments table based on these joins. I presume my join is the issue but I don't see the problem. Thoughts/Suggestions? Thanks, Chuck

  • Binding to a List<object> in silverlight problem.

    - by cw
    Hello, Can someone suggest what I am doing wrong? Basically I have a List Items, when an item gets added to the list I am resetting the collection to the viewmodel property. The only way I can get it to work is if I null the member object out before reassigning the binding. Any suggestions on how to go about updating a UI when an item gets added to a List? public List<Item> RegisteredItems { get { return m_vRegisteredItems; } set { m_vRegisteredItems= null; NotifyPropertyChanged("RegisteredItems"); m_vRegisteredItems= value; NotifyPropertyChanged("RegisteredItems"); } }

    For brevity's sake in my code, i'd like to be able to do the following: having a collection, find the first element matching a lambda expression; if it exists, return the value of a property or function. If it doesn't exist, return null. var stuff = {"I", "am", "many", "strings", "obviously"}; var UpperValueOfAString = stuff.FirstOrDefault(s => s.contains("bvi")).ToUpper(); // would return "OBVIOUSLY" var UpperValueOfAStringWannabe = stuff.FirstOrDefault(s => s.contains("unknown token")).ToUpper(); // would return null Is it possible with some linq-syntax-fu or do i have to check explicitly for the return value before proceeding?

  • node.js - strange behavior of coffeescript compiler

    - by JimBob
    I noticed an unexplainable behavior of the coffeescript compiler for me :) For example: getImage: (req, res) => realty_id = req.query.id if (realty_id?) Result ImageController.prototype.getImage = function(req, res) { var realty_id, _this = this; realty_id = req.query.id; if ((realty_id != null) But actually the last line should be: if ((typeof realty_id !== "undefined" && realty_id !== null)) When I comment out "realty_id = req.query.id" it works well. Has anyone a explanation for that?

  • Problem with non data bound value in ASP.NET DropDownList.

    - by ProfK
    I'm trying to 'inject' an [All Regions] item into my regions dropdown, as follows: <asp:DropDownList ID="regionList" runat="server" AutoPostBack="true" AppendDataBoundItems="true" Width="200px" DataSourceID="regionDataSource" DataTextField="Desc" DataValueField="RegionId"> <asp:ListItem Selected="True" Value="">[All Regions]</asp:ListItem> </asp:DropDownList> I also have a rank dropdown, for taxi ranks in a region, with the following select parameter: <asp:ControlParameter ControlID="regionList" Name="RegionId" PropertyName="SelectedValue" Type="Int32" DefaultValue="" ConvertEmptyStringToNull="true" /> So the expected behaviour is that when [All Regions] is selected, the ranks dropdown should get a null parameter, and mt SQL selects all ranks, for all regions. I know my SQL works with a null parameter, but the ranks dropdown is not data binding when I select [All Regions] on the region list. It binds when I select a region from the DB, but keeps that binding when I select [All Regions] again. What am I doing wrong?

  • Two collections and a for loop. (Urgent help needed) Checking an object variable against an inputted

    - by Elliott
    Hi there, I'm relatively new to java, I'm certain the error is trivial. But can't for the life of me spot it. I have an end of term exam on monday and currently trying to get to grips with past papers! Anyway heregoes, in another method (ALGO_1) I search over elements of and check the value H_NAME equals a value entered in the main. When I attempt to run the code I get a null pointer exception, also upon trying to print (with System.out.println etc) the H_NAME value after each for loop in the snippet I also get a null statement returned to me. I am fairly certain that the collection is simply not storing the data gathered up by the Scanner. But then again when I check the collection size with size() it is about the right size. Either way I'm pretty lost and would appreciate the help. Main questions I guess to ask are: from the readBackground method is the data.add in the wrong place? is the snippet simply structured wrongly? oh and another point when I use System.out.println to check the Background object values name, starttime, increment etc they print out fine. Thanks in advance.(PS im guessing the formatting is terrible, apologies.) snippet of code: for(Hydro hd: hydros){ System.out.println(hd.H_NAME); for(Background back : backgs){ System.out.println(back.H_NAME); if(back.H_NAME.equals(hydroName)){ //get error here public static Collection<Background> readBackground(String url) throws IOException { URL u = new URL(url); InputStream is = u.openStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader b = new BufferedReader(isr); String line =""; Vector<Background> data = new Vector<Background>(); while((line = b.readLine())!= null){ Scanner s = new Scanner(line); String name = s.next(); double starttime = Double.parseDouble(s.next()); double increment = Double.parseDouble(s.next()); double sum = 0; double p = 0; double nterms = 0; while((s.hasNextDouble())){ p = Double.parseDouble(s.next()); nterms++; sum += p; } double pbmean = sum/nterms; Background SAMP = new Background(name, starttime, increment, pbmean); data.add(SAMP); } return data; } Edit/Delete Message

  • Translating this query in LINQ ? (list of like)

    - by Erick
    I would like to translate this query in LINQ ... it is very easy to construct if we do it in pure SQL but in dynamically created LINQ query (building a search query based on user input) it's a whole new story. SELECT * FROM MyTable WHERE 1=1 AND Column2 IN (1,2,3) AND ( Column1 LIKE '%a%' OR Column1 LIKE '%b%' ) Now to try to construct this we tried it this way : if(myOjb.Column2Collection != null) query = query.where(f => f.Column2.Contains(myOjb.Column2Collection)); if(myObj.Column1Collection != null) { // tough part here ? //query = query.Where(); ... } So what would be the best aproach to this normally ? Note that I am aware of the SqlMethod.Like, tho I can't figure a way to implement it here ...

  • Unlock device, display a text, then lock again

    - by Waza_Be
    For the need of my application, I need to display a message on the screen even if the lockscreen is enabled, then wait 3 seconds, than I have to lock again the phone as I don't want it to make unwanted phone calls in your pockets. First part is easy: if (PreferenceManager.getDefaultSharedPreferences( getBaseContext()).getBoolean("wake", false)) { KeyguardManager kgm = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE); boolean isKeyguardUp = kgm.inKeyguardRestrictedInputMode(); WakeLocker.acquire(ProtoBenService.this); Intent myIntent = new Intent(ProtoBenService.this,LockActivity.class); myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); if (isKeyguardUp) { ProtoBenService.this.startActivity(myIntent); } else Toast.makeText(ProtoBenService.this.getBaseContext(), intention, Toast.LENGTH_LONG).show(); WakeLocker.release(); } With this class: public abstract class WakeLocker { private static PowerManager.WakeLock wakeLock; public static void acquire(Context ctx) { if (wakeLock != null) wakeLock.release(); PowerManager pm = (PowerManager) ctx.getSystemService(Context.POWER_SERVICE); wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "CobeIm"); wakeLock.acquire(); } public static void release() { if (wakeLock != null) wakeLock.release(); wakeLock = null; } } And the Activity: public class LockActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Window window = getWindow(); window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); TextView tv = new TextView(this); tv.setText("This is working!"); tv.setTextSize(45); setContentView(tv); Runnable mRunnable; Handler mHandler = new Handler(); mRunnable = new Runnable() { @Override public void run() { LockActivity.this.finish(); } }; mHandler.postDelayed(mRunnable, 3 * 1000); } } So, this is nice, the phone can display my text! The only problem comes when I want to lock again the phone, it seems that locking the phone is protected by the system... Programmatically turning off the screen and locking the phone how to lock the android programatically I think that my users won't understand the Device Admin and won't be able to activate it. Is there any workaround to lock the screen without the Device Admin stuff?

I fill this dictionary temporarily to test some things.. public void FillTemp(Dictionary<int, Item> itemInfo) { Random r = new Random(); for(int i =0; i < mapSize.Width; i++) { for(int j=0; j<mapSize.Height; j++) { Location temp = new Location(i, j, 0); int rint = r.Next(0, (itemInfo.Count - 1)); Tile t = new Tile(new Item(rint, rint)); tiles[temp] = t; } } } and in my main program code Map m = new Map(10, 10); m.FillTemp(iInfo); Tile t = m.GetTile(new Location(2, 2, 0)); //The problem line now, if I add a breakpoint in my code, I can clearly see that my instance (m) of the map class is filled with pairs via the function above, but when I try to access a value with the GetTile function: public Tile GetTile(Location location) { if(this.tiles.ContainsKey(location)) { return this.tiles[location]; } else { return null; } } it ALWAYS returns null. Again, if I view inside the Map object and find the Location key where x=2,y=2,z=0 , I clearly see the value being a Tile that FillTemp generated.. Why is it doing this? I've had no problems with a Dictionary such as this so far. I have no idea why it's returning null. and again, when debugging, I can CLEARLY see that the Map instance contains the Location key it says it does not... very frustrating. Any clues? Need any more info? Help would be greatly appreciated :)
