  • Session is null when inherit from System.Web.UI.Page

    - by Andreas K.
    I want to extend the System.Web.UI.Page-class with some extra stuff. In the ctor I need the value of a session-variable. The problem is that the Session-object is null... public class ExtendedPage : System.Web.UI.Page { protected foo; public ExtendedPage() { this.foo = (int)HttpContext.Current.Session["foo"]; // NullReferenceException } } If I move the part with the session-object into the Load-Event everything works fine... public class ExtendedPage : System.Web.UI.Page { protected foo; public ExtendedPage() { this.Load += new EventHandler(ExtendedPage_Load); } void ExtendedPage_Load(object sender, EventArgs e) { this.foo = (int)HttpContext.Current.Session["foo"]; } } Why is the Session-object null in the first case??

  • Switching Javascript Function states

    - by webzide
    Dear experts, I would like to implement a API of Javascript that sort of resemble a light switch. For instance, there are two buttons on the actual HTML page act as the UI. Both of the buttons have event handlers that invokes a different function. Each function have codes that act like a state, for instance. button1.onclick=function (){ $("div").click( //code effects 2 ) } button2.onclick=function (){ $("div").click( //Code effects 2 ) } I the code works fine on the surface but the 2 state functions overlap. the effects is going to take place for the rest of the way until the next reload of the document. Basically what I want to achieve is that when 1 button is clicked, it will switch "OFF" the state of function invoked by the other button and vice versa. Thus, the effects achieved are unique are not overlapped. Is there anyway to achieve this or could any experts point me to the right direction. Thanks in advance.

  • jQuery Tools - Range Input with Mousewheel support

    - by pspahn
    I've got a nice looking horizontal scroller that uses the Range Input feature of jQ Tools. Mouse wheel scrolling support would be awesome, and I'm sure it can work, just not sure how to get it set up. I've got the generic setup: var scroll = jQuery('#scroll'); jQuery(':range').rangeinput({ speed: 0, progress: true, onSlide: function(ev, step) { scroll.css({left: -step}); }, change: function(e, i) { scroll.animate({left: -i}, "fast"); } }); The doc page ( http://jquerytools.org/documentation/toolbox/mousewheel.html ) for mousewheel gives an example: $("#myelement").mousewheel(function(event, delta) { }); But I'm not sure how this hooks in. Other tools in the package simply allow the option: mousewheel: true Unfortunately that doesn't work on range input. Any advice appreciated. Thank you.

  • concatenating results from SQL query and NULL columns

    - by Curtis
    I need to concatenate several columns of a table into a single value, then show that value in an asp dropdownlist. The SQL code I'm issuing is as follows: SELECT UserID, CustomerNum, UserName + ' - ' + UserAddress + ',' + UserCity + ' ' + UserState AS UserInfo FROM Users WHERE (CustomerNum = @CustomerNum) ORDER BY UserName I then set 'UserInfo' as the text field in the dropdownlist. This generally works, except occasionally one of the columns in the database is null (for example, UserState). When that happens, the entire concatenation is null, and I get an empty entry in the dropdownlist. Is there something in SQLServer that will allow me to ignore those NULL results, or will I have to code something up in the DataBind event? Thanks

  • How to design this simple database?

    - by Vafello
    I have 2 tables - one storing user information (id, username, password) and the second one storing information about events (id, name, description, date, username(represents the user who created the event)). I would like to implement 'favourite events' functionality. This would allow the user to store his favourite events and later display them in a list. I am not sure how to implement this in terms of design. I need a simple solution. Something like storing the IDs of favourite events in a field in the user table. I am using mysql and php. Can anyone point me to the right direction?

  • Sending message from one server to another in Twisted

    - by Casey Patton
    I've implemented my servers in the following way: def makeServer(application, port): factory = protocol.ServerFactory() factory.protocol = MyChat factory.clients = [] internet.TCPServer(port, factory).setServiceParent(application) application = service.Application("chatserver") server1 = makeServer(application, port=1025) server2 = makeServer(application, port=1026) server3 = makeServer(application, port=1027) Note that MyChat is an event handling class that has a "receiveMessage" action: def lineReceived(self, line): print "received", repr(line) for c in self.factory.clients: c.transport.write(message + '\n') I want server1 to be able to pass messages to server2. Rather, I want server1 to be treated as a client of server2. If server1 receives the message "hi" then I want it to send that same exact message to server2. How can I accomplish this?

  • Setting ID to a control inside repeater itemtemplate

    - by toraan
    Inside repeater's itemtemplate I have a Panel server control. I need to assign special Id for it, because I need to work with some javascript functions that use this Id. In repeater ItemDataBound event I have this: pnlButtonsPanel.ID = pnlButtonsPanel.ID + DataBinder.Eval(e.Item.DataItem, "ID"); But this solution is not good because after a postback the page is re -rendered and I lose the new ID. (And I don't want to rebind repeater after every postback) I tried to set the ID on aspx page like that: <asp:Panel id='<%# Eval("ID") %>' and some other variations but always get compile errors.

  • Border in DrawRectangle

    - by undsoft
    Well, I'm coding the OnPaint event for my own control and it is very nescessary for me to make it pixel-accurate. I've got a little problem with borders of rectangles. See picture: These two rectangles were drawn with the same location and size parameters, but using different size of the pen. See what happend? When border became larger it has eaten the free space before the rectangle (on the left). I wonder if there is some kind of property which makes border be drawn inside of the rectangle, so that the distance to rectangle will always be the same. Thanks.

  • .net Attributes that handle exceptions - usage on a property accessor

    - by Mr AH
    Hi, well I know from my asp.net mvc experience that you can have attributes that handle exceptions (HandleErrorAttribute). As far as I can tell the Controller class has some OnException event which may be integral to this behaviour. However, I want to do something similar in my own code: dream example: public String MyProperty { [ExceptionBehaviour(typeof(FormatException), MyExEnum.ClearValue)] set { _thing.prop = Convert.ToThing(value); } } .... The code above obviously makes very little sense, but is close to the kind of thing I wish to do. I want the attribute on the property set accessor to catch some type of exception and then deal with this in some custom way (or even just swallow it). Any ideas guys?

  • How can I use spinner setOnItemLongClickListener

    - by elCarda
    Hi, I am trying to make the Spinner behave different way when the user clicked on an item for a long time. I have spinner with some project and I want two things. When the user simple click on an item I want to normal select it. When the user have long clicked on an item I want to show dialog, with options like "Edit item", "Delete item". The first step works well (ofcourse), but when I am trying to do the second task I can not make spinner to generate longClicked event. Here is my code: this.projectSpinner = (Spinner) this.findViewById(R.id.SpinnerProjects); this.projectSpinner.setLongClickable(true); this.projectSpinner.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener(){ public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { Toast.makeText( AndroidTimeTrackerMainActivity.this, "Long click", Toast.LENGTH_SHORT).show(); // This toast doesn't show up. return false; } });

  • How can a Delphi TPersistent object calculate its own deserialization time?

    - by mjustin
    For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions.

  • When to use Vanilla Javascript vs. jQuery?

    - by jondavidjohn
    I have noticed while monitoring/attempting to answer common jQuery questions, that there are certain practices using javascript, instead of jQuery, that actually enable you to write less and do ... well the same amount. And may also yield performance benefits. A specific example $(this) vs this Inside a click event referencing the clicked objects id jQuery $(this).attr("id"); Javascript this.id; Are there any other common practices like this? Where certain Javascript operations could be accomplished easier, without bringing jQuery into the mix. Or is this a rare case? (of a jQuery "shortcut" actually requiring more code) EDIT : While I appreciate the answers regarding jQuery vs. plain javascript performance, I am actually looking for much more quantitative answers. While using jQuery, instances where one would actually be better off (readability/compactness) to use plain javascript instead of using $(). In addition to the example I gave in my original question.

  • Is there a standard format string in ASP.NET to convert 1/2/3/... to 1st/2nd/3rd...?

    - by Dr. Monkey
    I have an integer in an Access database, which is being displayed in ASP.NET. The integer represents the position achieved by a competitor in a sporting event (1st, 2nd, 3rd, etc.), and I'd like to display it with a standard suffix like 'st', 'nd', 'rd' as appropriate, rather than just a naked number. An important limitation is that this is for an assignment which specifies that no VB or C# code be written (in fact it instructs code behind files to be deleted entirely). Ideally I'd like to use a standard format string if available, otherwise perhaps a custom string (I haven't worked with format strings much, and this isn't high enough priority to dedicate significant time to*, but I am very curious about whether there's a standard string for this). (* The assignment is due tonight, and I've learned the hard way that I can't afford to spend time on things that don't get the marks, even if they irk me significantly.)

  • C# Custom Control Properties load before Load and arrays are empties

    - by Wildhorn
    Hello, I made a custom control with custom properties. When I modify these properties in the "Form.cs [Design]", I need stuff to happens (it fill some arrays and modify the look of the control), so I call a function within the "set" of the property. All of this works good. My problem is that when I run the program with my custom control, it seems that properties "set" is called, which will call the function, but then, my arrays seems now to have lost all their values and the function use these arrays, but now because they are all empty, it crashes due to NullException blahblahblah. It also seems that properties "set" is called before the control Load (which I guess is called only when it is added to my Form, and not when the Form load). So question is, why does my arrays become empty once I try to run the Form and is there an event that is called before that when the Form load? Thanks

  • Saving WPF WIndow and Position

    - by moogs
    What would be the best way to save the window position and size in a WPF app? Currently, I'm saving the window size and position of a WPF App. Here are the events I handle: SourceInitialized : The saved info is loaded on to the window WindowClosing : The current info is saved to the backing store (I copied this from an example). The problem is, when the window is minimized and restored, the settings from the last WindowClosing is retrieved. Now, the StateChanged event fire AFTER the window has minimized, so it does not seem to be what i need. Thanks
