  • XSL to show highest number of copies in catalog.xml file

    - by SANJAY RAO
    In this the catalog.xml file. I have two books who have the same inventory (i.e. 20). I want to write an XSL file that will display the highest number of copies of a book in a catalog. If there are two or more books of the same inventory then they have to be displayed. <catalog> <Book> <sku>12345</sku> <title>Beauty Secrets</title> <condition>New</condition> <current_inventory>20</current_inventory> <price>99.99</price> </Book> <Book> <sku>54321</sku> <title>Picturescapes</title> <current_inventory>20</current_inventory> <condition>New</condition> <price>50.00</price> </Book> <Book> <sku>33333</sku> <title>Tourist Perspectives</title> <condition>New</condition> <current_inventory>0</current_inventory> <price>75.00</price> </Book> <Book> <sku>10001</sku> <title>Fire in the Sky</title> <condition>Used</condition> <current_inventory>0</current_inventory> <price>10.00</price> </Book> </catalog> Below is my catalog3.xsl file which is able to display only one out of the two books: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" > <xsl:variable name="max"/> <xsl:template match="/"> <html> <body> <h2>Titles of Books for which Most Copies are Available</h2> <table border="2"> <tr bgcolor="#9acd32"> <th>Title</th> <th>No of Copies</th> </tr> <xsl:apply-templates/> </table> </body> </html> </xsl:template> <xsl:template match="catalog"> <xsl:for-each select="Book"> <xsl:sort select="current_inventory" data-type="number" order="descending"/> <tr> <xsl:if test="position()= 1"> <p><xsl:value-of select="$max = "/></p> <td><xsl:value-of select="title"/></td> <td><xsl:value-of select="current_inventory"/></td> </xsl:if> </tr> </xsl:for-each> </xsl:template> </xsl:stylesheet> Could anybody correct me to achieve my goal of displaying all the copies having the same maximum inventory in the catalog. Thanks.

  • Asp.net mvc application deployment / security issues

    - by WestDiscGolf
    I'll start with appologies; I wasn't sure if this was best posted here of Server Fault so if its in the wrong place then please move :-) Basic information I have written the first module of a new application at work. This is written using Visual Studio 2010, targetting .net 3.5 (at the moment) and asp.net mvc 2. This has been working fine during development running on the built in Development server from VS but however does not work once deployed to IIS 7/7.5. To deploy the application, I have built it in release mode and created a deployment package by right clicking on the project in the solution explorer (this will be done with an automated build in tfs once upgrade from the beta). This has then been imported into IIS on the server. The application is using windows/domain authentication. Issue #1 I can fire up internet explorer and browse to the application from a client computer as well as on a remote desktop connection. I can execute the code which reads/stores data in Session fine from the IE instance on the remote desktop but if I browse to it from the client pc it seems to lose the session state. I click on the form submit and the page refreshes and doesn't execute the required code. I've tried setting with; InProc, SQLServer and StateServer. but with no luck :-( Issue #2 As part of the application it views PDF and Tiff documents on the fly which are on a network share on the office network and creates thumbnails if the document hasn't been viewed before. This works if running on the machine the application is deployed to; however when browsing from a client pc I get an error saying: Access to the path '\\fileserver\folder\file.tif' is denied Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UnauthorizedAccessException: Access to the path '\\fileserver\folder\file.TIF' is denied. ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. As this is on a different server the user is not accessible. To get round this I have tried: 1 - setting the application pool to run as domain administrator (I know this is a security risk, but I'm just trying to get it to work at the moment!) 2 - to set the log on account for World Wide Web Publishing service to be the domain admin . When trying to restart the service I get ... Windows could not start the World Wide Web Publishing Service service on the Local Computer. Error 1079: The account specified for this service is different from the account specified fro the other services running in the same process. Any pointers/help would be much appriciated as I'm pulling my hair out (of what little I have left). Update I've been using this funky little tool I found - DelegConfig v2 beta (Delegation / Kerberos Configuration Tool). This has been really usefull. So I've got the accessing of the file share working (there is a test page which will read the files) so now I've just got the issue of passing through the users credentials through to the SQL Server (wans't my choice to do it this way!!) to execute the queries etc. but I can't get it to log on as the user. It tries to access it as "NT Authority\Network Service" which doesn't have a sql login (as should be the logged on user). My connection string is: <add name="User" connectionString="Data Source=.;Integrated Security=True" providerName="System.Data.SqlClient" /> No initial catalog is specified as the system is over multiple dbs (also wasn't my choice!!). I really appriciate all the help so far! :-) Any further hints?!

  • Domain Validation in a CQRS architecture

    - by Jupaol
    Basically I want to know if there is a better way to validate my domain entities. This is how I am planning to do it but I would like your opinion The first approach I considered was: class Customer : EntityBase<Customer> { public void ChangeEmail(string email) { if(string.IsNullOrWhitespace(email)) throw new DomainException(“...”); if(!email.IsEmail()) throw new DomainException(); if(email.Contains(“@mailinator.com”)) throw new DomainException(); } } I actually do not like this validation because even when I am encapsulating the validation logic in the correct entity, this is violating the Open/Close principle (Open for extension but Close for modification) and I have found that violating this principle, code maintenance becomes a real pain when the application grows up in complexity. Why? Because domain rules change more often than we would like to admit, and if the rules are hidden and embedded in an entity like this, they are hard to test, hard to read, hard to maintain but the real reason why I do not like this approach is: if the validation rules change, I have to come and edit my domain entity. This has been a really simple example but in RL the validation could be more complex So following the philosophy of Udi Dahan, making roles explicit, and the recommendation from Eric Evans in the blue book, the next try was to implement the specification pattern, something like this class EmailDomainIsAllowedSpecification : IDomainSpecification<Customer> { private INotAllowedEmailDomainsResolver invalidEmailDomainsResolver; public bool IsSatisfiedBy(Customer customer) { return !this.invalidEmailDomainsResolver.GetInvalidEmailDomains().Contains(customer.Email); } } But then I realize that in order to follow this approach I had to mutate my entities first in order to pass the value being valdiated, in this case the email, but mutating them would cause my domain events being fired which I wouldn’t like to happen until the new email is valid So after considering these approaches, I came out with this one, since I am going to implement a CQRS architecture: class EmailDomainIsAllowedValidator : IDomainInvariantValidator<Customer, ChangeEmailCommand> { public void IsValid(Customer entity, ChangeEmailCommand command) { if(!command.Email.HasValidDomain()) throw new DomainException(“...”); } } Well that’s the main idea, the entity is passed to the validator in case we need some value from the entity to perform the validation, the command contains the data coming from the user and since the validators are considered injectable objects they could have external dependencies injected if the validation requires it. Now the dilemma, I am happy with a design like this because my validation is encapsulated in individual objects which brings many advantages: easy unit test, easy to maintain, domain invariants are explicitly expressed using the Ubiquitous Language, easy to extend, validation logic is centralized and validators can be used together to enforce complex domain rules. And even when I know I am placing the validation of my entities outside of them (You could argue a code smell - Anemic Domain) but I think the trade-off is acceptable But there is one thing that I have not figured out how to implement it in a clean way. How should I use this components... Since they will be injected, they won’t fit naturally inside my domain entities, so basically I see two options: Pass the validators to each method of my entity Validate my objects externally (from the command handler) I am not happy with the option 1 so I would explain how I would do it with the option 2 class ChangeEmailCommandHandler : ICommandHandler<ChangeEmailCommand> { public void Execute(ChangeEmailCommand command) { private IEnumerable<IDomainInvariantValidator> validators; // here I would get the validators required for this command injected, and in here I would validate them, something like this using (var t = this.unitOfWork.BeginTransaction()) { var customer = this.unitOfWork.Get<Customer>(command.CustomerId); this.validators.ForEach(x =. x.IsValid(customer, command)); // here I know the command is valid // the call to ChangeEmail will fire domain events as needed customer.ChangeEmail(command.Email); t.Commit(); } } } Well this is it. Can you give me your thoughts about this or share your experiences with Domain entities validation EDIT I think it is not clear from my question, but the real problem is: Hiding the domain rules has serious implications in the future maintainability of the application, and also domain rules change often during the life-cycle of the app. Hence implementing them with this in mind would let us extend them easily. Now imagine in the future a rules engine is implemented, if the rules are encapsulated outside of the domain entities, this change would be easier to implement

  • MVC keeping the PartialView in its own context - ignore the main view holding the partial view

    - by Mike
    I'm looking at the partialview components of the MVC Framework. i want my partial view to be handled in its own action and for the rest of the view to handle itself, but i'm getting an exception because the main page is not getting its view fired. Am i going around this the wrong way? My Main View (Jobs/Index.aspx): <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication3.Models.JobViewModel>" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% Html.RenderPartial("JobListing", Model.Jobs); %> </asp:Content> The partialview (Jobs/JobListing.ascx): <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<MvcApplication3.Models.Job>>" %> <table> <tr> <td> Job Title </td> <td> Job Location</td> </tr> <% foreach (var job in Model) { %> <tr> <td> <%= job.Title %> </td> <td> <%= job.Location %> </td> </tr> <% } %> <% Html.BeginForm("DoSomeStuff", "Job", null, FormMethod.Post); %> <%= Html.TextBox("SomeInfo") %> <button type="submit" id="submit" /> <% Html.EndForm(); %> The main controller for both the main view (Index) and the partialview (DoSomeStuff()) public class JobController : Controller { public ActionResult Index() { JobProvider provider = new JobProvider(Session); JobViewModel vm = new JobViewModel(); vm.Jobs = provider.GetJobs(); return View(vm); } public PartialViewResult DoSomeStuff() { return PartialView("JobListing"); } } As you can see in the partial view, it has its own form that posts to the Action called DoSomeStuff(). i want this action to handle any data submitted from that form. but when the form is submitted the main action (Index) does not fire and then i get an exception as the Model (.Models.JobViewModel) is not passed to the view that the partialview (JobListings) lives in. basically what im saying is, if i have a myview.aspx with lots of html.RenderPartialView('apartialview') that have forms in them, can i get it so these forms post to their own actions and the main view (with what ever model it inherits) is handled as well. Rather then having all the form submitting code in the main action for the view. am i do this wrong?

  • UIView, UIScrollView and UITextFields problem calling Method

    - by Jeff Groby
    I have a view with several embedded UITextFields, this UIView is subordinated to a UIScrollView in IB. Each text field is supposed to invoke a method called updateText defined in the viewcontroller implementation file when the user is done editing the field. For some reason, the method updateText never gets invoked. Anyone have any ideas how to go about fixing this? The method fired off just fine when the UIScrollView was not present in the project but the keyboard would cover the text fields during input, which was annoying. Now my textfields move up above the keyboard when it appears, but won't fire off the method when done editing. Here is my implementation file: #import "MileMarkerViewController.h" @implementation MileMarkerViewController @synthesize scrollView,milemarkerLogDate,milemarkerDesc,milemarkerOdobeg,milemarkerOdoend,milemarkerBusiness,milemarkerPersonal,milemarker; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Initialization code } return self; } - (BOOL) textFieldShouldReturn: (UITextField*) theTextField { return [theTextField resignFirstResponder]; } - (void)viewDidLoad { [super viewDidLoad]; [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWasShown:) name: UIKeyboardDidShowNotification object: nil]; [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWasHidden:) name: UIKeyboardDidHideNotification object: nil]; keyboardShown = NO; // 1 [scrollView setContentSize: CGSizeMake( 320, 480)]; // 2 } - (void)keyboardWasShown:(NSNotification*)aNotification { if (keyboardShown) return; NSDictionary* info = [aNotification userInfo]; // Get the size of the keyboard. NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; // Resize the scroll view (which is the root view of the window) CGRect viewFrame = [scrollView frame]; viewFrame.size.height -= keyboardSize.height; scrollView.frame = viewFrame; // Scroll the active text field into view. CGRect textFieldRect = [activeField frame]; [scrollView scrollRectToVisible:textFieldRect animated:YES]; keyboardShown = YES; } - (void)keyboardWasHidden:(NSNotification*)aNotification { NSDictionary* info = [aNotification userInfo]; // Get the size of the keyboard. NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; // Reset the height of the scroll view to its original value CGRect viewFrame = [scrollView frame]; viewFrame.size.height += keyboardSize.height; [scrollView scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES]; scrollView.frame = viewFrame; keyboardShown = NO; } - (void)textFieldDidBeginEditing:(UITextField *)textField { activeField = textField; } - (void)textFieldDidEndEditing:(UITextField *)textField { activeField = nil; } - (IBAction)updateText:(id) sender { NSLog(@"You just entered: %@",self.milemarkerLogDate.text); self.milemarker.logdate = self.milemarkerLogDate.text; self.milemarker.desc = self.milemarkerDesc.text; self.milemarker.odobeg = self.milemarkerOdobeg.text; self.milemarker.odoend = self.milemarkerOdoend.text; self.milemarker.business = self.milemarkerBusiness.text; self.milemarker.personal = self.milemarkerPersonal.text; NSLog(@"Original textfield is set to: %@",self.milemarker.logdate); [self.milemarker updateText]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview.

  • Why does this valid Tkinter code crash when mixed with a bit of PyWin32?

    - by Erlog
    So I'm making a very small program for personal use in tkinter, and I've run into a really strange wall. I'm mixing tkinter with the pywin32 bindings because I really hate everything to do with the syntax and naming conventions of pywin32, and it feels like tkinter gets more done with far less code. The strangeness is happening in the transition between the pywin32 clipboard watching and my program's reaction to it in tkinter. My window and all its controls are being handled in tkinter. The pywin32 bindings are doing clipboard watching and clipboard access when the clipboard changes. From what I've gathered about the way the clipboard watching pieces of pywin32 work, you can make it work with anything you want as long as you provide pywin32 with the hwnd value of your window. I'm doing that part, and it works when the program first starts. It just doesn't seem to work when the clipboard changes. When the program launches, it grabs the clipboard and puts it into the search box and edit box just fine. When the clipboard is modified, the event I want to fire off is firing off...except that event that totally worked before when the program launched is now causing a weird hang instead of doing what it's supposed to do. I can print the clipboard contents to stdout all I want if the clipboard changes, but not put that same data into a tkinter widget. It only hangs like that if it starts to interact with any of my tkinter widgets after being fired off by a clipboard change notification. It feels like there's some pywin32 etiquette I've missed in adapting the clipboard-watching sample code I was using over to my tkinter-using program. Tkinter apparently doesn't like to produce stack traces or error messages, and I can't really even begin to know what to look for trying to debug it with pdb. Here's the code: #coding: utf-8 #Clipboard watching cribbed from ## {{{ http://code.activestate.com/recipes/355593/ (r1) import pdb from Tkinter import * import win32clipboard import win32api import win32gui import win32con import win32clipboard def force_unicode(object, encoding="utf-8"): if isinstance(object, basestring) and not isinstance(object, unicode): object = unicode(object, encoding) return object class Application(Frame): def __init__(self, master=None): self.master = master Frame.__init__(self, master) self.pack() self.createWidgets() self.hwnd = self.winfo_id() self.nextWnd = None self.first = True self.oldWndProc = win32gui.SetWindowLong(self.hwnd, win32con.GWL_WNDPROC, self.MyWndProc) try: self.nextWnd = win32clipboard.SetClipboardViewer(self.hwnd) except win32api.error: if win32api.GetLastError () == 0: # information that there is no other window in chain pass else: raise self.update_search_box() self.word_search() def word_search(self): #pdb.set_trace() term = self.searchbox.get() self.resultsbox.insert(END, term) def update_search_box(self): clipboardtext = "" if win32clipboard.IsClipboardFormatAvailable(win32clipboard.CF_TEXT): win32clipboard.OpenClipboard() clipboardtext = win32clipboard.GetClipboardData() win32clipboard.CloseClipboard() if clipboardtext != "": self.searchbox.delete(0,END) clipboardtext = force_unicode(clipboardtext) self.searchbox.insert(0, clipboardtext) def createWidgets(self): self.button = Button(self) self.button["text"] = "Search" self.button["command"] = self.word_search self.searchbox = Entry(self) self.resultsbox = Text(self) #Pack everything down here for "easy" layout changes later self.searchbox.pack() self.button.pack() self.resultsbox.pack() def MyWndProc (self, hWnd, msg, wParam, lParam): if msg == win32con.WM_CHANGECBCHAIN: self.OnChangeCBChain(msg, wParam, lParam) elif msg == win32con.WM_DRAWCLIPBOARD: self.OnDrawClipboard(msg, wParam, lParam) # Restore the old WndProc.

  • Ado.net Fill method not throwing error on running a Stored Procedure that does not exist.

    - by Mike
    I am using a combination of the Enterprise library and the original Fill method of ADO. This is because I need to open and close the command connection myself as I am capture the event Info Message Here is my code so far // Set Up Command SqlDatabase db = new SqlDatabase(ConfigurationManager.ConnectionStrings[ConnectionName].ConnectionString); SqlCommand command = db.GetStoredProcCommand(StoredProcName) as SqlCommand; command.Connection = db.CreateConnection() as SqlConnection; // Set Up Events for Logging command.StatementCompleted += new StatementCompletedEventHandler(command_StatementCompleted); command.Connection.FireInfoMessageEventOnUserErrors = true; command.Connection.InfoMessage += new SqlInfoMessageEventHandler(Connection_InfoMessage); // Add Parameters foreach (Parameter parameter in Parameters) { db.AddInParameter(command, parameter.Name, (System.Data.DbType)Enum.Parse(typeof(System.Data.DbType), parameter.Type), parameter.Value); } // Use the Old Style fill to keep the connection Open througout the population // and manage the Statement Complete and InfoMessage events SqlDataAdapter da = new SqlDataAdapter(command); DataSet ds = new DataSet(); // Open Connection command.Connection.Open(); // Populate da.Fill(ds); // Dispose of the adapter if (da != null) { da.Dispose(); } // If you do not explicitly close the connection here, it will leak! if (command.Connection.State == ConnectionState.Open) { command.Connection.Close(); } ... Now if I pass into the variable StoredProcName = "ThisProcDoesNotExists" And run this peice of code. The CreateCommand nor da.Fill through an error message. Why is this. The only way I can tell it did not run was that it returns a dataset with 0 tables in it. But when investigating the error it is not appearant that the procedure does not exist. EDIT Upon further investigation command.Connection.FireInfoMessageEventOnUserErrors = true; is causeing the error to be surpressed into the InfoMessage Event From BOL When you set FireInfoMessageEventOnUserErrors to true, errors that were previously treated as exceptions are now handled as InfoMessage events. All events fire immediately and are handled by the event handler. If is FireInfoMessageEventOnUserErrors is set to false, then InfoMessage events are handled at the end of the procedure. What I want is each print statement from Sql to create a new log record. Setting this property to false combines it as one big string. So if I leave the property set to true, now the question is can I discern a print message from an Error ANOTHER EDIT So now I have the code so that the flag is set to true and checking the error number in the method void Connection_InfoMessage(object sender, SqlInfoMessageEventArgs e) { // These are not really errors unless the Number >0 // if Number = 0 that is a print message foreach (SqlError sql in e.Errors) { if (sql.Number == 0) { Logger.WriteInfo("Sql Message",sql.Message); } else { // Whatever this was it was an error throw new DataException(String.Format("Message={0},Line={1},Number={2},State{3}", sql.Message, sql.LineNumber, sql.Number, sql.State)); } } } The issue now that when I throw the error it does not bubble up to the statement that made the call or even the error handler that is above that. It just bombs out on that line The populate looks like // Populate try { da.Fill(ds); } catch (Exception e) { throw new Exception(e.Message, e); } Now even though I see the calling codes and methods still in the Call Stack, this exception does not seem to bubble up?

  • Editing a Gridview row with drop-down lists gets too wide - how can I use popup panels instead?

    - by David
    I have a series of GridViews in a Tab Panel - databound to a generic List of Business Objects. The columns in the Gridview are all similar to the following: <asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName"> <ItemTemplate> <asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:DropDownList ID="ddlCompany" runat="server"></asp:DropDownList> </EditItemTemplate> </asp:TemplateField> The GridView generates the "Edit" link at the beginning of the row, all the events fire ok. The problem is that the data is getting long. When in 'display mode', it's fine because the GridView control is smart enough to break some text into multiple lines (in particular Project, Title and Worker names can get pretty long). The problem come in editing mode. Drop-down lists DON'T break entries into multiple lines (for obvious reasons). Going into Edit ode on a row in the Gridview can make the Griview expand horizontally to twice the screen size (blowing through the width limits in the Master page and CSS but that's only a related problem). What I need is something like the ModalPopup - but trying to tie it to an ID in an EditItemTemplate gives me errors when the page renders (because the 'ddlXXXX' doesn't exist at the time). In addition I don't know how to dynamically populate the panel so that I can get a response from it (like the ID of the Company they selected). I'm also trying to avoid javascript and would like this to be a 'pure' aspx/code-behind solution (for simplicity's sake among others). All the examples I find are of Modal Popups with the panels pre-defined. Even if it (the popup panel) were something like a list of checkboxes, it could be databound to the SortedList I have ready to go and an OK/Cancel button combination to accept or ignore things. I'm just not sure of what goes where. I'm open to suggestions. Thanks in advance. EDIT: Final solution looks as follows: <asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName"> <ItemTemplate> <asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:LinkButton ID="lnkCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:LinkButton> <asp:Panel ID="pnlCompany" runat="server" style="display:none"> <div> <asp:DropDownList ID="ddlCompany" runat="server" ></asp:DropDownList> <br/> <asp:ImageButton ID="btnOKCo" runat="server" ImageUrl="~/Images/greencheck.gif" OnCommand="PopupButton_Command" CommandName="SelectCO" /> <asp:ImageButton ID="btnCxlCo" runat="server" ImageUrl="~/Images/RedX.gif" /> </div> </asp:Panel> <cc1:ModalPopupExtender ID="mpeCompany" runat="server" TargetControlID="lnkCompany" PopupControlID="pnlCompany" BackgroundCssClass="modalBackground" CancelControlID="btnCxlCo" DropShadow="true" PopupDragHandleControlID="pnlCompany" /> </EditItemTemplate> </asp:TemplateField> And in the code-behind, lstIDLabor is the generic List of data lines (of which Company is one of the properties that is also a business object) that is bound to the GridView: Sub PopupButton_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Dim intRow As Integer Dim intVal As Integer RestoreFromSessionVariables() Select Case e.CommandName Case "SelectCO" intRow = grdIDCostLabor.EditIndex Dim ddlCo As DropDownList = CType(grdIDCost.Rows(intRow).FindControl("ddlCompany"), DropDownList) intVal = ddlCo.SelectedValue lstIDLabor(intRow).CompanyID = intVal lstIDLabor(intRow).Company = Company.Read(intVal) Case Else ' End Select MakeSessionVariables() BindGrids() End Sub

  • Php template caching design

    - by Thomas
    Hello to all, I want to include caching in my app design. Caching templates for starters. The design I have used so far is very modular. I have created an ORM implementation for all my tables and each table is represented by the corresponding class. All the requests are handled by one controller which routes them to the appropriate webmethod functions. I am using a template class for handling UI parts. What I have in mind for caching includes the implementation of a separate Cache class for handling caching with the flexibility to either store in files, apc or memcache. Right now I am testing with file caching. Some thoughts Should I include the logic of checking for cached versions in the Template class or in the webmethods which handle the incoming requests and which eventually call the Template class. In the first case, things are pretty simple as I will not have to change anything more than pass the template class an extra argument (whether to load from cache or not). In the second case however, I am thinking of checking for a cached version immediately in the webmethod and if found return it. This will save all the processing done until the logic reaches the template (first case senario). Both senarios however, rely on an accurate mechanism of invalidating caches, which brings as to Invalidating caches As I see it (and you can add your input freely) a template cached file, becomes invalidate if: a. the expiration set, is reached. b. the template file itself is updated (ie by the developer when adding a new line) c. the webmethod that handles the request changes (ie the developer adds/deletes something in the code) d. content coming from the db and ending in the template file is modified I am thinking of storing a json encoded array inside the cached file. The first value will be the expiration timestamp of the cache. The second value will be the modification time of the php file with the code handling the request (to cope with option c above) The third will be the content itself The validation process I am considering, according to the above senarios, is: a. If the expiration of the cached file (stored in the array) is reached, delete the cache file b. if the cached file's mod time is smaller than the template's skeleton file mod time, delete the cached file c. if the mod time of the php file is greated than the one stored in the cache, delete the cached file. d. This is tricky. In the ORM implementation I ahve added event handlers (which fire when adding, updating, deleting objects). I could delete the cache file every time an object thatprovides content to the template, is modified. The problem is how to keep track which cached files correpond to each schema object. Take this example, a user has his shortprofile page and a full profile page (2 templates) These templates can be cached. Now, every time the user modifies his profile, the event handler would need to know which templates or cached files correspond to the User, so that these files can be deleted. I could store them in the db but I am looking for a beter approach

  • Apache/PHP serving file multiple times

    - by easement
    I have a system with a download.php page. The page takes and id and loads a file based on from the DB Record and then serves it up. I've noticed a couple instances where files are requested multiple times in short time spans (20ms). Times that are too quick for human input. There are plenty of instances where the downloader functions fine. However, in taking a closer look at the downloader’s usage, I did see some interesting behavior. For instance, the IP address xxx.xxx.xxx.xxx (which is one in a range owned by xxxxxx.de in Germany) came to the site through Google. They browsed around and then came to the page http://site.com/xxxx/press+125.php There they issued a request for /download.php?id=/ZZ/n+aH55Y= (a PDF) at 9:04:23AM. That alone is not a big deal. However, what is interesting is that the server seems to have been quite preoccupied with serving that request. In the logs the request first completes between 9:09:48 and 9:10:00. It looks like the user must have gotten tired of waiting during that time and requested the document two more times. Between 09:14:47 and 09:15:00 the same request appears again, except it is from 9:04:43AM, 20ms later than the first request. Then it pops up a third time, with a request that started at 09:05:06 completing between 09:19:55 and 09:19:58! I’m suspicious of that document. In looking through the logs I see other instances where it takes the server a little while to handle that specific file. Check out this list of requests from zzz.zzz.zzz.zzz[different than above] for the file /download.php?id=/ZZ/n+aH55Y= (the same docuemnt as before): Request time Complete Time 04:32:43 04:33:36 04:32:50 04:33:36 04:32:51 04:33:38 04:33:05 04:33:38 04:33:34 04:33:42 04:33:05 04:33:42 So something is definitely going on. Whether it has to do with this specific document tripping up the server, the download.php page’s code, or if we’re just seeing the evidence of some server level overload as it plays out in real time I’m not yet sure. In fairness, there are other instances of people downloading /download.php?id=/ZZ/n+aH55Y= (the same PDF) without error. However, it is interesting that the multiple processes only seem to happen with this one file, and then only when it is accessed through the page http://site.com/press+125.php . It bears further investigation if there’s something amiss inside the code that causes the system to fire off multiple download requests that occupy the server. I don't know if this press+125.php is a rabbit hole, but there is weird consicence. Any ideas? I'm totally out of ideas. Apache maxed out? Things like that. ///DOWNLOAD.php $file = new files(); $file->comparison_filter("id", "=", $id); //sql to load if ($file->load()) { $file->serve(); } //FILES function serve() { if ($this->is_loaded) { if (file_exists($this->get_value("filename"))) { if ($this->get_value("content_type") != "") { header("Content-Type: " . $this->get_value("content_type")); } header("Content-Length: " . filesize($this->get_value("filename"))); if ($this->get_value("flag_image") == 0 || $this->get_value("flag_image") == false) { header("Cache-Control: private"); header("Content-Disposition: attachment; filename=" . urlencode($this->get_value("original_filename"))); } set_time_limit(0); @readfile($this->get_value("filename")); exit; } } }

  • window.requestFileSystem fails/events firing multiple times in PhoneGap Cordova 3

    - by ezycheez
    cordova 3.1.0-0.2.0 Droid Razr M Android 4.1.2 Windows 7 New to PhoneGap/Cordova. Running one of the filesystem demos from http://docs.phonegap.com/en/3.1.0/cordova_file_file.md.html#File. Using "cordova run android" to compile the code and run it on the phone attached via USB. Problem #1: When the app first starts I get alert("1") twice and then nothing else. Problem #2: When I kick of the code via the button onclick I get the following alert pattern: 1, 2, 2, 3, 3, 4, 6, 5, 7, 4, 6, 5, 7. Some of that makes sense based on the code flow but most of them are firing twice. I'm suspecting problem #2 is being caused by some asynchronous calls hanging out from the first attempt but no matter how long I wait those events don't fire until I kick of the code via the button. So why is the requestFileSystem call failing even though it is waiting for deviceready and why is the other code getting intermingled? Any thoughts are appreciated. <!DOCTYPE html> <html> <head> <title>FileReader Example</title> <script type="text/javascript" charset="utf-8" src="cordova.js"></script> <script type="text/javascript" charset="utf-8"> // Wait for device API libraries to load // document.addEventListener("deviceready", onDeviceReady, false); // device APIs are available // function onDeviceReady() { alert("1"); window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail); } function gotFS(fileSystem) { alert("2"); fileSystem.root.getFile("readme.txt", null, gotFileEntry, fail); } function gotFileEntry(fileEntry) { alert("3"); fileEntry.file(gotFile, fail); } function gotFile(file) { alert("4"); readDataUrl(file); alert("5"); readAsText(file); } function readDataUrl(file) { alert("6"); var reader = new FileReader(); reader.onloadend = function (evt) { console.log("Read as data URL"); console.log(evt.target.result); }; reader.readAsDataURL(file); } function readAsText(file) { alert("7"); var reader = new FileReader(); reader.onloadend = function (evt) { console.log("Read as text"); console.log(evt.target.result); }; reader.readAsText(file); } function fail(error) { alert("8"); console.log(error.code); } </script> </head> <body> <h1>Example</h1> <p>Read File</p> <button onclick="onDeviceReady();">Read File</button> </body> </html>

  • onCommand on button not firing inside gridView??

    - by sah302
    This is really driving me crazy. I've got a button inside a gridview to remove that item from the gridview (its datasource is a list). I've got the list being saved to session anytime a change is being made to it, and on page_load check if that session variable is empty, if not, then set that list to bind to the gridview. Code Behind: Public accomplishmentTypeDao As New AccomplishmentTypeDao() Public accomplishmentDao As New AccomplishmentDao() Public userDao As New UserDao() Public facultyDictionary As New Dictionary(Of Guid, String) Public facultyList As New List(Of User) Public associatedFaculty As New List(Of User) Public facultyId As New Guid Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'If Not Session("associatedFaculty") Is Nothing Then' ' Dim associatedFacultyArray As User() = DirectCast(Session("associatedFaculty"), User())' ' associatedFaculty = associatedFacultyArray.ToList()' 'End If' Page.Title = "Add a New Faculty Accomplishment" ddlAccomplishmentType.DataSource = accomplishmentTypeDao.getEntireTable() ddlAccomplishmentType.DataTextField = "Name" ddlAccomplishmentType.DataValueField = "Id" ddlAccomplishmentType.DataBind() facultyList = userDao.getListOfUsersByUserGroupName("Faculty") For Each faculty As User In facultyList facultyDictionary.Add(faculty.Id, faculty.LastName & ", " & faculty.FirstName) Next If Not Page.IsPostBack Then ddlFacultyList.DataSource = facultyDictionary ddlFacultyList.DataTextField = "Value" ddlFacultyList.DataValueField = "Key" ddlFacultyList.DataBind() End If gvAssociatedUsers.DataSource = associatedFaculty gvAssociatedUsers.DataBind() End Sub Protected Sub deleteUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) facultyId = New Guid(e.CommandArgument.ToString()) associatedFaculty.Remove(associatedFaculty.Find(Function(user) user.Id = facultyId)) Session("associatedFaculty") = associatedFaculty.ToArray() gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub btnAddUser_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddUser.Click facultyId = New Guid(ddlFacultyList.SelectedValue) associatedFaculty.Add(facultyList.Find(Function(user) user.Id = facultyId)) Session.Add("associatedFaculty", associatedFaculty.ToArray()) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub Delete(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) End Sub End Class Markup: <asp:UpdatePanel ID="upAssociatedFaculty" runat="server" UpdateMode="Conditional"> <ContentTemplate> <p><b>Created By:</b> <asp:Label ID="lblCreatedBy" runat="server"></asp:Label></p> <p><b>Accomplishment Type: </b><asp:DropDownList ID="ddlAccomplishmentType" runat="server"></asp:DropDownList></p> <p><b>Accomplishment Applies To: </b><asp:DropDownList ID="ddlFacultyList" runat="server"></asp:DropDownList> &nbsp;<asp:Button ID="btnAddUser" runat="server" Text="Add Faculty" OnClientClick="incrementCounter();" /></p> <p> <asp:GridView ID="gvAssociatedUsers" runat="server" AutoGenerateColumns="false" GridLines="None" ShowHeader="false"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" Visible="False" /> <asp:TemplateField ShowHeader="False"> <ItemTemplate> <span style="margin-left: 15px;"> <p><%#Eval("LastName")%>, <%#Eval("FirstName")%> <asp:Button ID="btnUnassignUser" runat="server" CausesValidation="false" CommandArgument='<%# Eval("Id") %>' CommandName="Delete" OnCommand="deleteUser" Text='Remove' /></p> </span> </ItemTemplate> </asp:TemplateField> </Columns> <EmptyDataTemplate> <em>There are currently no faculty associated with this accomplishment.</em> </EmptyDataTemplate> </asp:GridView> </p> </ContentTemplate> </asp:UpdatePanel> Now here is the crazy part I am simply boggled by, if I uncomment the If Not Session... block of page_load, then deleteUser will never fire when btnUnassignUser is clicked. If I keep it commented out...it fires no problem, but then of course my list can never have more than one item since I am not loading the saved list from session into the gridview but just a fresh one. But the button click is being registered, because page_load is being stepped through again when I am viewing in debug mode, just deleteUser never fires. Why is this happening?? And how can I fix it??

  • How do I get a delete trigger working using fluent API in CTP5?

    - by user668472
    I am having trouble getting referential integrity dialled down enough to allow my delete trigger to fire. I have a dependent entity with three FKs. I want it to be deleted when any of the principal entities is deleted. For principal entities Role and OrgUnit (see below) I can rely on conventions to create the required one-many relationship and cascade delete does what I want, ie: Association is removed when either principal is deleted. For Member, however, I have multiple cascade delete paths (not shown here) which SQL Server doesn't like, so I need to use fluent API to disable cascade deletes. Here is my (simplified) model: public class Association { public int id { get; set; } public int roleid { get; set; } public virtual Role role { get; set; } public int? memberid { get; set; } public virtual Member member { get; set; } public int orgunitid { get; set; } public int OrgUnit orgunit { get; set; } } public class Role { public int id { get; set; } public virtual ICollection<Association> associations { get; set; } } public class Member { public int id { get; set; } public virtual ICollection<Association> associations { get; set; } } public class Organization { public int id { get; set; } public virtual ICollection<Association> associations { get; set; } } My first run at fluent API code looks like this: protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder) { DbDatabase.SetInitializer<ConfDB_Model>(new ConfDBInitializer()); modelBuilder.Entity<Member>() .HasMany(m=>m.assocations) .WithOptional(a=>a.member) .HasForeignKey(a=>a.memberId) .WillCascadeOnDelete(false); } My seed function creates the delete trigger: protected override void Seed(ConfDB_Model context) { context.Database.SqlCommand("CREATE TRIGGER MemberAssocTrigger ON dbo.Members FOR DELETE AS DELETE Assocations FROM Associations, deleted WHERE Associations.memberId = deleted.id"); } PROBLEM: When I run this, create a Role, a Member, an OrgUnit, and an Association tying the three together all is fine. When I delete the Role, the Association gets cascade deleted as I expect. HOWEVER when I delete the Member I get an exception with a referential integrity error. I have tried setting ON CASCADE SET NULL because my memberid FK is nullable but SQL complains again about multiple cascade paths, so apparently I can cascade nothing in the Member-Association relationship. To get this to work I must add the following code to Seed(): context.Database.SqlCommand("ALTER TABLE dbo.ACLEntries DROP CONSTRAINT member_aclentries"); As you can see, this drops the constraint created by the model builder. QUESTION: this feels like a complete hack. Is there a way using fluent API for me to say that referential integrity should NOT be checked, or otherwise to get it to relax enough for the Member delete to work and allow the trigger to be fired? Thanks in advance for any help you can offer. Although fluent APIs may be "fluent" I find them far from intuitive.

  • JSF2 - Problems with Composite Components and Validatiors

    - by Shadowman
    I've created some Facelets to make developing our pages easier. Particularly, I've created a series of Facelets for input components. I have 1 Facelet, <xxx:input /> that displays a label around the input field. Beyond that, I have Facelets like <xxx:inputText /> and <xxx:inputSecret /> that render the actual input field. Each of these makes use of <xxx:input /> to display the label. The Facelet looks something like this: <html ...> <composite:interface> ... </composite:interface> <composite:implementation> <label><h:outputText value="#{cc.attrs.labelText}" /></label> <composite:insertChildren /> </composite:implementation> </html> The <xxx:inputText /> Facelet would then look like this... <html ...> <composite:interface> ... </composite:interface> <composite:implementation> <xxx:input labelText=...> <h:inputText id="myinput" ... /> </xxx:input> </composite:implementation> </html> Everything renders just fine, but I am having troubles when trying to add <f:validator /> or other validation tags. From what I've read, I have to add a tag to my Facelet. So, I added <composite:editableValueHolder name="myinput" targets="myinput" /> line in the interface section. However, I still do not see my validator being fired. I have something like this in my .xhtml file... ... <xxx:inputText value="..."> <f:validateLength minimum="10" /> </xxx:inputText> ... Regardless of the input I enter, the validator never seems to fire and I never get an error message. A coworker suggested that it is due to the target ID I am using and the fact that it is wrapped by the <xxx:input /> Facelet. Do I need to incorporate the parent component ID in my target definition? Is there something else that I'm missing? It works just fine if I exclude the <xxx:input /> Facelet, so I'm assuming it's something related to that, but don't know how to solve it. Any help you can provide is GREATLY appreciated.

  • How to create a dynamically built Context Menu clickEvent

    - by Chris
    C#, winform I have a DataGridView and a context menu that opens when you right click a specific column. What shows up in the context menu is dependant on what's in the field clicked on - paths to multiple files (the paths are manipulated to create a full UNC path to the correct file). The only problem is that I can't get the click working. I did not drag and drop the context menu from the toolbar, I created it programmically. I figured that if I can get the path (let's call it ContextMenuChosen) to show up in MessageBox.Show(ContextMenuChosen); I could set the same to System.Diagnostics.Process.Start(ContextMenuChosen); The Mydgv_MouseUp event below actually works to the point where I can get it to fire off MessageBox.Show("foo!"); when something in the context menu is selected but that's where it ends. I left in a bunch of comments below showing what I've tried when it one of the paths are clicked. Some result in empty strings, others error (Object not set to an instance...). I searched code all day yesterday but couldn't find another way to hook up a dynamically built Context Menu clickEvent. Code and comments: ContextMenu m = new ContextMenu(); // SHOW THE RIGHT CLICK MENU private void Mydgv_MouseClick(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Right) { int currentMouseOverCol = Mydgv.HitTest(e.X, e.Y).ColumnIndex; int currentMouseOverRow = Mydgv.HitTest(e.X, e.Y).RowIndex; if (currentMouseOverRow >= 0 && currentMouseOverCol == 6) { string[] paths = myPaths.Split(';'); foreach (string path in paths) { string UNCPath = "\\\\1.1.1.1\\c$\\MyPath\\"; string FilePath = path.Replace("c:\\MyPath\\", @""); m.MenuItems.Add(new MenuItem(UNCPath + FilePath)); } } m.Show(Mydgv, new Point(e.X, e.Y)); } } // SELECTING SOMETHING IN THE RIGHT CLICK MENU private void Mydgv_MouseUp(object sender, MouseEventArgs e) { DataGridView.HitTestInfo hitTestInfo; if (e.Button == MouseButtons.Right) { hitTestInfo = Mydgv.HitTest(e.X, e.Y); // If column is first column if (hitTestInfo.Type == DataGridViewHitTestType.Cell && hitTestInfo.ColumnIndex == 6) { //MessageBox.Show(m.ToString()); ////MessageBox.Show(m.Tag.ToString()); //MessageBox.Show(m.Name.ToString()); //MessageBox.Show(m.MenuItems.ToString()); ////MessageBox.Show(m.MdiListItem.ToString()); // MessageBox.Show(m.Name); //if (m.MenuItems.Count > 0) //MessageBox.Show(m.MdiListItem.Text); //MessageBox.Show(m.ToString()); //MessageBox.Show(m.MenuItems.ToString()); //Mydgv.ContextMenu.Show(m.Name.ToString()); //MessageBox.Show(ContextMenu.ToString()); //MessageBox.Show(ContextMenu.MenuItems.ToString()); //MenuItem.text //MessageBox.Show(this.ContextMenu.MenuItems.ToString()); } m.MenuItems.Clear(); } } I'm very close to completing this so any help would be much appreciated.

  • How do you send a named pipe string from umnanaged to managed code space?

    - by billmcf
    I appear to have a named pipes 101 issue. I have a very simple set up to connect a simplex named pipe transmitting from a C++ unmanaged app to a C# managed app. The pipe connects, but I cannot send a "message" through the pipe unless I close the handle which appears to flush the buffer and pass the message through. It's like the message is blocked. I have tried reversing the roles of client/server and invoking them with different Flag combinations without any luck. I can easily send messages in the other direction from C# managed to C++ unmanaged. Does anyone have any insight. Can any of you guys successfully send messages from C++ unmanaged to C# managed? I can find plenty of examples of intra amanged or unmanaged pipes but not inter managed to/from unamanged - just claims to be able to do it. In the listings, I have omitted much of the wrapper stuff for clarity. The key bits I believe that are relevant are the pipe connection/creation/read and write methods. Don't worry too much about blocking/threading here. C# Server side // This runs in its own thread and so it is OK to block private void ConnectToClient() { // This server will listen to the sending client if (m_InPipeStream == null) { m_InPipeStream = new NamedPipeServerStream("TestPipe", PipeDirection.In, 1); } // Wait for client to connect to our server m_InPipeStream.WaitForConnection(); // Verify client is running if (!m_InPipeStream.IsConnected) { return; } // Start listening for messages on the client stream if (m_InPipeStream != null && m_InPipeStream.CanRead) { ReadThread = new Thread(new ParameterizedThreadStart(Read)); ReadThread.Start(m_InPipeStream); } } // This runs in its own thread and so it is OK to block private void Read(object serverObj) { NamedPipeServerStream pipeStream = (NamedPipeServerStream)serverObj; using (StreamReader sr = new StreamReader(pipeStream)) { while (true) { string buffer = "" ; try { // Blocks here until the handle is closed by the client-side!! buffer = sr.ReadLine(); // <<<<<<<<<<<<<< Sticks here } catch { // Read error break; } // Client has disconnected? if (buffer == null || buffer.Length == 0) break; // Fire message received event if message is non-empty if (MessageReceived != null && buffer != "") { MessageReceived(buffer); } } } } C++ client side // Static - running in its own thread. DWORD CNamedPipe::ListenForServer(LPVOID arg) { // The calling app (this) is passed as the parameter CNamedPipe* app = (CNamedPipe*)arg; // Out-Pipe: connect as a client to a waiting server app->m_hOutPipeHandle = CreateFile("\\\\.\\pipe\\TestPipe", GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); // Could not create handle if (app->m_hInPipeHandle == NULL || app->m_hInPipeHandle == INVALID_HANDLE_VALUE) { return 1; } return 0; } // Sends a message to the server BOOL CNamedPipe::SendMessage(CString message) { DWORD dwSent; if (m_hOutPipeHandle == NULL || m_hOutPipeHandle == INVALID_HANDLE_VALUE) { return FALSE; } else { BOOL bOK = WriteFile(m_hOutPipeHandle, message, message.GetLength()+1, &dwSent, NULL); //FlushFileBuffers(m_hOutPipeHandle); // <<<<<<< Tried this return (!bOK || (message.GetLength()+1) != dwSent) ?

  • Using resize to getScript if above x pixels (jQuery)

    - by user1065573
    So I have an issue with this script. It basically is loading the script on any resize event. I have it working if lets say... - User has window size above 768 (getScipt() and content by .load() in that script) - Script will load (and content) - User for some reason window size goes below 768 (css hides #div) - User re-sizes again above 768, And does not load the script again! (css displays the div) Great. Works right. Now.. (for some cray reason) - User has window size below 768 (Does NOT getScript() or nothing) - User re-sizes above 768 and stops at any px (getScript and content) - User re-sizes again anything above 768 (It getScript AGAIN) I need it to only get script once. Ive used some code from here jQuery: How to detect window width on the fly? (edit - i found this, which he has the same issue of loading a script once.) Problem with function within $(window).resize - using jQuery And others i lost the links to :/ When i first found this problem I was using something like this, then i added the allcheckWidth() to solve problem. But it does not. var $window = $(window); function checkWidth() { var windowsize = $window.width(); ////// LETS GET SOME THINGS IF IS DESKTOP var $desktop_load = 0; if (windowsize >= 768) { if (!$desktop_load) { // GET DESKTOP SCRIPT TO KEEP THINGS QUICK $.getScript("js/desktop.js", function() { $desktop_load = 1; }); } else { } } ////// LETS GET SOME THINGS IF IS MOBILE if (windowsize < 768) { } } checkWidth(); function allcheckWidth () { var windowsize = $window.width(); //// IF WINDOW SIZE LOADS < 768 THEN CHANGES >= 768 LOAD ONCE var $desktop_load = 0; if (!$desktop_load) { if (windowsize < 768) { if ( $(window).width() >= 768) { $.getScript("js/desktop.js", function() { $desktop_load = 1; }); } } } } $(window).resize(allcheckWidth); Now im using something like this which makes more sense? $(function() { $(window).resize(function() { var $desktop_load = 0; //Dekstop if (window.innerWidth >= 768) { if (!$desktop_load) { // GET DESKTOP SCRIPT TO KEEP THINGS QUICK $.getScript("js/desktop.js", function() { $desktop_load + 1; }); } else { } } if (window.innerWidth < 768) { if (window.innerWidth >= 768) { if (!$desktop_load) { // GET DESKTOP SCRIPT TO KEEP THINGS QUICK $.getScript("js/desktop.js", function() { $desktop_load + 1; }); } else { } } } }) .resize(); // trigger resize event }) Ty for future response. Edit - To give an example, in desktop.js i have a gif that loads before "abc" content, that gets inserted by .load(). On resize this gif will show up and the .load() in desktop.js will fire again. So if getScript was only being called once, it should not be doing anything again in desktop.js. Confusing?

  • Flash Mouse.hide() cmd+tab(alt+tab) bring the mouse back

    - by DickieBoy
    Having a bit of trouble with Mouse.show() and losing focus of the swf This isn't my demo: but its showing the same bug http://www.foundation-flash.com/tutorials/as3customcursors/ What i do to recreate it is: mouse over the swf, hit cmd+tab to highlight another window, result is that the mouse is not brought back and is still invisible, (to get it back go to the window bar at the top of the screen and click something). I have an area in which movement is detected and an image Things I have tried package { import flash.display.Sprite; import flash.display.MovieClip; import com.greensock.*; import flash.events.*; import flash.utils.Timer; import flash.events.TimerEvent; import flash.utils.*; import flash.ui.Mouse; public class mousey_movey extends MovieClip { public var middle_of_the_flash; //pixels per second public var speeds = [0,1,3,5,10]; public var speed; public var percentage_the_mouse_is_across_the_screen; public var mouse_over_scrollable_area:Boolean; public var image_move_interval; public function mousey_movey() { middle_of_the_flash = stage.stageWidth/2; hot_area_for_movement.addEventListener(MouseEvent.MOUSE_OVER, mouseEnter); hot_area_for_movement.addEventListener(MouseEvent.MOUSE_OUT, mouseLeave); hot_area_for_movement.addEventListener(MouseEvent.MOUSE_MOVE, mouseMove); stage.addEventListener(Event.MOUSE_LEAVE, show_mouse); stage.addEventListener(MouseEvent.MOUSE_OUT, show_mouse); stage.addEventListener(Event.DEACTIVATE,show_mouse); hot_area_for_movement.alpha=0; hot_area_for_movement.x=0; hot_area_for_movement.y=34; } public function show_mouse(e) { trace(e.type) trace('show_mouse') Mouse.show(); } public function onActivate(e) { trace('activate'); Mouse.show(); } public function onDeactivate(e) { trace('deactivate'); } public function get_speed(percantage_from_middle):int { if(percantage_from_middle > 80) { return speeds[4] } else { if(percantage_from_middle > 60) { return speeds[3] } else { if(percantage_from_middle > 40) { return speeds[2] } else { if(percantage_from_middle > 20) { return speeds[1] } else { return 0; } } } } } public function mouseLeave(e:Event):void{ Mouse.show(); clearInterval(image_move_interval); } public function mouseEnter(e:Event):void{ Mouse.hide(); image_move_interval = setInterval(moveImage,1); } public function mouseMove(e:Event):void { percentage_the_mouse_is_across_the_screen = Math.round(((middle_of_the_flash-stage.mouseX)/middle_of_the_flash)*100); speed = get_speed(Math.abs(percentage_the_mouse_is_across_the_screen)); airplane_icon.x = stage.mouseX; airplane_icon.y = stage.mouseY; } public function stageMouseMove(e:Event):void{ Mouse.show(); } public function moveImage():void { if(percentage_the_mouse_is_across_the_screen > 0) { moving_image.x+=speed; airplane_icon.scaleX = -1; } else { moving_image.x-=speed; airplane_icon.scaleX = 1; } } } } Nothing too fancy, im just scrolling an image left of right at a speed which is generated by how far you are from the middle of the stage, and making an airplane moveclip follow the mouse. The events: stage.addEventListener(Event.MOUSE_LEAVE, show_mouse); stage.addEventListener(MouseEvent.MOUSE_OUT, show_mouse); stage.addEventListener(Event.DEACTIVATE,show_mouse); All fire and work correctly when in the browser, seem a little buggy when running a test through flash, was expecting this as ive experienced it before. The deactivate call even runs when testing and cmd+tabbing but shows no mouse. Any help on the matter is appreciated Thanks, Dickie

  • Installing UCMA 3.0 and Creating a Communications Server "14"Trusted Application Pool

    A lot of setup and administration tasks have gotten a lot easier in Communications Server 14; one of them is building an application server to develop and run your UCMA 3.0 applications on. In this post, Ill walk you through installing the UCMA 3.0 Core SDK and creating a Trusted Application Pool on the server, thus adding it to the Communications Server 14 topology and allowing you to host and run UCMA 3.0 applications on it. Note: These instructions will change slightly as the bits get updated for the eventual Beta release I will update this post as soon as I get a chance to run this setup on a more recent build. Im doing the install on a simple Communications Server 14 topology consisting of the following Windows Server 2008 R2 Hyper-V images: DC Domain Controller ExchangeUM Exchange Server 2010 CS-SE Microsoft Communications Server 2010 Standard Edition TS Development machine Ill walk through setting up UCMA 3.0 on the TS VM, which is a fully patched Windows Server 2008 R2 machine that is joined to the Fabrikam domain.   Im also running Visual Studio 2010 on this VM because I intend to use it as a development machine.  In a future post, Ill walk through installing just the UCMA 3.0 run time to build a true production UCMA application server. Im making a couple of assumptions here: You have an existing CS 2010 site and cluster configured(well look at this in a future post) Youre starting with a fully patched Windows Server 2008 R2 machine The machine is joined to your domain This walkthrough was done in my Fabrikam VM environment but can easily be modified for your own environment. Installing the UCMA 3.0 SDK Lets start by installing the UCMA 3.0 SDK.  Run UcmaSdkWebDownload.msi to kick off the SDK installer package extract process. The installed package is extracted to C: >> Program Files >> Microsoft UCMA 3.0 >> SDK Installer Package.  Browse there and run setup.exe. Click Install to install the UCMA 3.0 Core SDK and Workflow SDK. Install Communications Server Core Components UCMA 3.0 introduces a new concept called Auto-provisioning, which is most easily explained from the developer point of view.  Remember what your app.config looked it in UCMA 2.0?  You had to store the application GRUU, the trusted contact SIP Uri, the port for your application, and the name of the certificate authority. Thats all gone with auto-provisioning all you need in your app.config is your ApplicationId, e.g.: urn:application:MyApplication. How does CS 2010 do this? All of the applications configuration data is associated with the applications id.  UCMA also queries a replicated copy of the Central Management Database to retrieve the applications configuration data and also the configuration data for any endpoints. In this step, well run Bootstrapper.exe to install the CS Core components, this checked for the following components and installs them if they are not already present: VcRedist Sqlexpress Sqlnativeclient Sqlbackcompat Ucmaredist OcsCore.msi Open a command window at C: >> Program Files >> Microsoft Communications Server 2010 >> Deployment and run the following command: Bootstrapper.exe /BootstrapReplica /MinCache /SourceDirectory:"%ProgramFiles%\Microsoft UCMA 3.0\SDK Installer Package\Prereq\BootstrapperCache" Create a New Trusted Application Pool The next step is to create a new trusted application pool for the new server.  Fire up the Communications Server Management Shell from Start >> Microsoft Communications Server 2010 >> Communications Server Management Shell and enter the following PowerShell command: New-CsTrustedApplicationPool -Identity <FQDN of Server> -Registrar <FQDN of CS Server> -Site <CS Site Name> Verify that the new server was added to the CS topology by running the following PowerShell command: (Get-CsTopology -AsXml).ToString() > Topology.xml This created a file called Topology.xml in the directory that you ran the command from.  Open the file and find the Clusters section and look for a node for the new server. The Cluster Fqdn is the name of your server, and note the name of the Site that this Cluster is a part of. <Cluster Fqdn="appsrv.fabrikam.com" RequiresReplication="true" RequiresSetup="true"> <ClusterId SiteId="UcMarketing2" Number="5" /> <Machine OrdinalInCluster="1" Fqdn="appsrv.fabrikam.com"> <NetInterface InterfaceSide="Primary" InterfaceNumber="1" IPAddress="0.0.0.0" /> </Machine> </Cluster> Configure CS Management Store Replication At this point, we have the CS Core components installed and the server configured as a trusted application pool.  We now need to set up replication so that the Central Management Store replicates down to the new server. From the Communications Server Management Shell, run the following PowerShell command to enable the Replica service on the new server: Enable-CSReplica The Replica service is enabled, but hasn't done anything yet. This can be verified by running the following PowerShell command to check the replication status for the various servers in the topology: Get-CSManagementStoreReplicationStatus You can see in the screenshot below that the UpToDate property of the new server is still False Run the following PowerShell command to force the replication to run: Invoke-CSManagementStoreReplicationStatus Run Get-CSManagementStoreReplicationStatus again to verify that the new service is now up to date Request and Set a New Certificate The last step in the process is to request a new certificate from the certificate authority on the domain and assign it to the new server. From the Communications Server Management Shell, run the following PowerShell command to request a new certificate: Request-CSCertificate -Action new -Type default -CA <Domain Controller FQDN>\<Certificate Authority> Setting the -Verbose switch on the cmdlet creates an Xml file with its output. Open the Xml file and copy the thumbprint of the generated certificate. <?xml version="1.0" encoding="utf-8"?> <Action Name="Request-CsCertificate" Time="20100512T212258"> <Action Name="Request-CsCertificate" Time="20100512T212258"> <Info Title="Connection" Time="20100512T212258">Data Source=(local)\rtclocal;Initial Catalog=xds;Integrated Security=True</Info> <Action Time="20100512T212258"> <Info Title="Certificate use" Time="20100512T212258">urn:certref:default</Info> <Info Title="Subject distinguished name" Time="20100512T212258">CN="appsrv2.fabrikam.com"</Info> <Info Time="20100512T212259">The certificate request is submitted to the Certification Authority dc.fabrikam.com\FabrikamCA.</Info> <Info Time="20100512T212259">The certificate was issued.</Info> <Info Time="20100512T212259">The certificate was imported with thumbprint AFC3C46E459C1A39AD06247676F3555826DBF705.</Info> <Complete Time="20100512T212259" /> </Action> <Info Title="command status" Time="20100512T212259">Command execution processing completed</Info> <Action Name="DeploymentXdsCmdlet.SaveCachedItems" Time="20100512T212259"> <Info Time="20100512T212259">0 updates</Info> <Complete Time="20100512T212259" /> </Action> <Info Title="command status" Time="20100512T212259">Command has completed</Info> </Action> </Action> Run the following PowerShell command to set the certificate: Set-CsCertificate -Type Default -Thumbprint <Thumbprint> Wrapping Up You now have a new UCMA 3.0 application server in your Communications Server 2010 server topology.  You can provision trusted applications and trusted application endpoints on the new server using the Communications Server 2010 Management Shell.  Well take a look at how to do that in another post. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Upgrading Team Foundation Server 2008 to 2010

    - by Martin Hinshelwood
    I am sure you will have seen my posts on upgrading our internal Team Foundation Server from TFS2008 to TFS2010 Beta 2, RC and RTM, but what about a fresh upgrade of TFS2008 to TFS2010 using the RTM version of TFS. One of our clients is taking the plunge with TFS2010, so I have the job of doing the upgrade. It is sometimes very useful to have a team member that starts work when most of the Sydney workers are heading home as I can do the upgrade without impacting them. The down side is that if you have any blockers then you can be pretty sure that everyone that can deal with your problem is asleep I am starting with an existing blank installation of TFS 2010, but Adam Cogan let slip that he was the one that did the install so I thought it prudent to make sure that it was OK. Verifying Team Foundation Server 2010 We need to check that TFS 2010 has been installed correctly. First, check the Admin console and have a root about for any errors. Figure: Even the SQL Setup looks good. I don’t know how Adam did it! Backing up the Team Foundation Server 2008 Databases As we are moving from one server to another (recommended method) we will be taking a backup of our TFS2008 databases and resorting them to the SQL Server for the new TFS2010 Server. Do not just detach and reattach. This will cause problems with the version of the database. If you are running a test migration you just need to create a backup of the TFS 2008 databases, but if you are doing the live migration then you should stop IIS on the TFS 2008 server before you backup the databases. This will stop any inadvertent check-ins or changes to TFS 2008. Figure: Stop IIS before you take a backup to prevent any TFS 2008 changes being written to the database. It is good to leave a little time between taking the TFS 2008 server offline and commencing the upgrade as there is always one developer who has not finished and starts screaming. This time it was John Liu that needed 10 more minutes to make his changes and check-in, so I always give it 30 minutes and see if anyone screams. John Liu [SSW] said:   are you doing something to TFS :-O MrHinsh [SSW UK][VS ALM MVP] said:   I have stopped TFS 2008 as per my emails John Liu [SSW] said:   haven't finish check in @_@   can we have it for 10mins? :) MrHinsh [SSW UK][VS ALM MVP] said:   TFS 2008 has been started John Liu [SSW] said:   I love you! -IM conversation at TFS Upgrade +25 minutes After John confirmed that he had everything done I turned IIS off again and made a cup of tea. There were no more screams so the upgrade can continue. Figure: Backup all of the databases for TFS and include the Reporting Services, just in case.   Figure: Check that all the backups have been taken Once you have your backups, you need to copy them to your new TFS2010 server and restore them. This is a good way to proceed as if we have any problems, or just plain run out of time, then you just turn the TFS 2008 server back on and all you have lost is one upgrade day, and not 10 developer days. As per the rules, you should record the number of files and the total number of areas and iterations before the upgrade so you have something to compare to: TFS2008 File count: Type Count 1 1845 2 15770 Areas & Iterations: 139 You can use this to verify that the upgrade was successful. it should however be noted that the numbers in TFS 2010 will be bigger. This is due to some of the sorting out that TFS does during the upgrade process. Restore Team Foundation Server 2008 Databases Restoring the databases is much more time consuming than just attaching them as you need to do them one at a time. But you may be taking a backup of an operational database and need to restore all your databases to a particular point in time instead of to the latest. I am doing latest unless I encounter any problems. Figure: Restore each of the databases to either a latest or specific point in time.     Figure: Restore all of the required databases Now that all of your databases are restored you now need to upgrade them to Team Foundation Server 2010. Upgrade Team Foundation Server 2008 Databases This is probably the easiest part of the process. You need to call a fire and forget command that will go off to the database specified, find the TFS 2008 databases and upgrade them to 2010. During this process all of the 6 main TFS 2008 databases are merged into the TfsVersionControl database, upgraded and then the database is renamed to TFS_[CollectionName]. The rename is only the database and not the physical files, so it is worth going back and renaming the physical file as well. This keeps everything neat and tidy. If you plan to keep the old TFS 2008 server around, for example if you are doing a test migration first, then you will need to change the TFS GUID. This GUID is unique to each TFS instance and is preserved when you upgrade. This GUID is used by the clients and they can get a little confused if there are two servers with the same one. To kick of the upgrade you need to open a command prompt and change the path to “C:\Program Files\Microsoft Team Foundation Server 2010\Tools” and run the “import” command in  “tfsconfig”. TfsConfig import /sqlinstance:<Previous TFS Data Tier>                  /collectionName:<Collection Name>                  /confirmed Imports a TFS 2005 or 2008 data tier as a new project collection. Important: This command should only be executed after adequate backups have been performed. After you import, you will need to configure portal and reporting settings via the administration console. EXAMPLES -------- TfsConfig import /sqlinstance:tfs2008sql /collectionName:imported /confirmed TfsConfig import /sqlinstance:tfs2008sql\Instance /collectionName:imported /confirmed OPTIONS: -------- sqlinstance         The sql instance of the TFS 2005 or 2008 data tier. The TFS databases at that location will be modified directly and will no longer be usable as previous version databases.  Ensure you have back-ups. collectionName      The name of the new Team Project Collection. confirmed           Confirm that you have backed-up databases before importing. This command will automatically look for the TfsIntegration database and verify that all the other required databases exist. In this case it took around 5 minutes to complete the upgrade as the total database size was under 700MB. This was unlike the upgrade of SSW’s production database with over 17GB of data which took a few hours. At the end of the process you should get no errors and no warnings. The Upgrade operation on the ApplicationTier feature has completed. There were 0 errors and 0 warnings. As this is a new server and not a pure upgrade there should not be a problem with the GUID. If you think at any point you will be doing this more than once, for example doing a test migration, or merging many TFS 2008 instances into a single one, then you should go back and rename the physical TfsVersionControl.mdf file to the same as the new collection. This will avoid confusion later down the line. To do this, detach the new collection from the server and rename the physical files. Then reattach and change the physical file locations to match the new name. You can follow http://www.mssqltips.com/tip.asp?tip=1122 for a more detailed explanation of how to do this. Figure: Stop the collection so TFS does not take a wobbly when we detach the database. When you try to start the new collection again you will get a conflict with project names and will require to remove the Test Upgrade collection. This is fine and it just needs detached. Figure: Detaching the test upgrade from the new Team Foundation Server 2010 so we can start the new Collection again. You will now be able to start the new upgraded collection and you are ready for testing. Do you remember the stats we took off the TFS 2008 server? TFS2008 File count: Type Count 1 1845 2 15770 Areas & Iterations: 139 Well, now we need to compare them to the TFS 2010 stats, remembering that there will probably be more files under source control. TFS2010 File count: Type Count 1 19288 Areas & Iterations: 139 Lovely, the number of iterations are the same, and the number of files is bigger. Just what we were looking for. Testing the upgraded Team Foundation Server 2010 Project Collection Can we connect to the new collection and project? Figure: We can connect to the new collection and project.   Figure: make sure you can connect to The upgraded projects and that you can see all of the files. Figure: Team Web Access is there and working. Note that for Team Web Access you now use the same port and URL as for TFS 2010. So in this case as I am running on the local box you need to use http://localhost:8080/tfs which will redirect you to http://localhost:8080/tfs/web for the web access. If you need to connect with a Visual Studio 2008 client you will need to use the full path of the new collection, http://[servername]/tfs/[collectionname] and this will work with all of your collections. With Visual Studio 2005 you will only be able to connect to the Default collection and in both VS2008 and VS2005 you will need to install the forward compatibility updates. Visual Studio Team System 2005 Service Pack 1 Forward Compatibility Update for Team Foundation Server 2010 Visual Studio Team System 2008 Service Pack 1 Forward Compatibility Update for Team Foundation Server 2010 To make sure that you have everything up to date, make sure that you run SSW Diagnostics and get all green ticks. Upgrade Done! At this point you can send out a notice to everyone that the upgrade is complete and and give them the connection details. You need to remember that at this stage we have 2008 project upgraded to run under TFS 2010 but it is still running under that same process template that it was running before. You can only “enable” 2010 features in a process template you can’t upgrade. So what to do? Well, you need to create a new project and migrate things you want to keep across. Souse code is easy, you can move or Branch, but Work Items are more difficult as you can’t move them between projects. This instance is complicated more as the old project uses the Conchango/EMC Scrum for Team System template and I will need to write a script/application to get the work items across with their attachments in tact. That is my next task! Technorati Tags: TFS 2010,TFS 2008,VS ALM
