• Understanding Flash SWC's imported into Flex Builder 3 and key framed animation

  - by Hank Scorpio

  I am trying to understand what is going on in a SWC that I am importing from Flash CS4 into Flex Builder 3. Specifically I am using a SWC supplied by a Designer as the animation for a custom preloader (a subclassed DownloadProgressBar). The issue I am trying to understand is, once the FlexEvent.INIT_COMPLETE is fired, I cleanup by removing the swc by running this : removeChild(myPreloader); myPreloader = null; though even after I have removed this (which is successful, as I have checked by comparing this.numChildren before and after the call) the key framed animation still continues to run (not visibly). This has been detected by the Designer placing a trace in the time line of the animation (in Flash). Can anyone tell me why is it, that even after I have removed the animation from the subclassed DownloadProgressBar, it still keeps running ? Also, is it standard practice when importing SWCs to manage the cleanup of resources from the Flash side of things (much like releasing memory in obj-c). I find it counter intuitive that removing the child from the Flex side does not stop the animation. Any clues to this would be greatly appreciated.

• How can I get PowerShell Added-Types to use Added References

  - by Scott Weinstein

  I'm working on a PoSh project that generates CSharp code, and then Add-Types it into memory. The new types use existing types in an on disk DLL, which is loaded via Add-Type. All is well and good untill I actualy try to invoke methods on the new types. Here's an example of what I'm doing: $PWD = "." rm -Force $PWD\TestClassOne* $code = " namespace TEST{ public class TestClassOne { public int DoNothing() { return 1; } } }" $code | Out-File tcone.cs Add-Type -OutputAssembly $PWD\TestClassOne.dll -OutputType Library -Path $PWD\tcone.cs Add-Type -Path $PWD\TestClassOne.dll $a = New-Object TEST.TestClassOne "Using TestClassOne" $a.DoNothing() "Compiling TestClassTwo" Add-Type -Language CSharpVersion3 -TypeDefinition " namespace TEST{ public class TestClassTwo { public int CallTestClassOne() { var a = new TEST.TestClassOne(); return a.DoNothing(); } } }" -ReferencedAssemblies $PWD\TestClassOne.dll "OK" $b = New-Object TEST.TestClassTwo "Using TestClassTwo" $b.CallTestClassOne() Running the above script gives the following error on the last line: Exception calling "CallTestClassOne" with "0" argument(s): "Could not load file or assembly 'TestClassOne,...' or one of its dependencies. The system cannot find the file specified." At AddTypeTest.ps1:39 char:20 + $b.CallTestClassOne <<<< () + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException What am I doing wrong?

• SQL 2005 indexed queries slower than unindexed queries

  - by uos??

  Adding a seemingly perfectly index is having an unexpectedly adverse affect on a query performance... -- [Data] has a predictable structure and a simple clustered index of the primary key: ALTER TABLE [dbo].[Data] ADD PRIMARY KEY CLUSTERED ( [ID] ) -- My query, joins on itself looking for a certain kind of "overlapping" records SELECT DISTINCT [Data].ID AS [ID] FROM dbo.[Data] AS [Data] JOIN dbo.[Data] AS [Compared] ON [Data].[A] = [Compared].[A] AND [Data].[B] = [Compared].[B] AND [Data].[C] = [Compared].[C] AND ([Data].[D] = [Compared].[D] OR [Data].[E] = [Compared].[E]) AND [Data].[F] <> [Compared].[F] WHERE 1=1 AND [Data].[A] = @A AND @CS <= [Data].[C] AND [Data].[C] < @CE -- Between a range [Data] has about a quarter-million records so far, 10% to 50% of the data satisfies the where clause depending on @A, @CS, and @CE. As is, the query takes 1 second to return about 300 rows when querying 10%, and 30 seconds to return 3000 rows when querying 50% of the data. Curiously, the estimated/actual execution plan indicates two parallel Clustered Index Scans, but the clustered index is only of the ID, which isn't part of the conditions of the query, only the output. ?? If I add this hand-crafted [IDX_A_B_C_D_E_F] index which I fully expected to improve performance, the query slows down by a factor of 8 (8 seconds for 10% & 4 minutes for 50%). The estimated/actual execution plans show an Index Seek, which seems like the right thing to be doing, but why so slow?? CREATE UNIQUE INDEX [IDX_A_B_C_D_E_F] ON [dbo].[Data] ([A], [B], [C], [D], [E], [F]) INCLUDE ([ID], [X], [Y], [Z]); The Data Engine Tuning wizard suggests a similar index with no noticeable difference in performance from this one. Moving AND [Data].[F] <> [Compared].[F] from the join condition to the where clause makes no difference in performance. I need these and other indexes for other queries. I'm sure I could hint that the query should refer to the Clustered Index, since that's currently winning - but we all know it is not as optimized as it could be, and without a proper index, I can expect the performance will get much worse with additional data. What gives?

• Error displaying a WinForm in Design mode with a custom control on it.

  - by George

  I have a UserControl that is part of a Class library. I reference this project from my solution. This adds a control from the referenced project to my toolbox. I add tghe control to a form. Everything looks good, I compile all and run. Perfect... But when I close the .frm with the control on it and re-open it, I get this error. The code continues to run. It may have something to do with namespaces. The original namespace was simply "Design" and this was ambiguous and conflicting so i decided to rename it. I think that's when my problems began.

• Webservice returning 403 error

  - by user48408

  I'm wondering whether I'm receiving the 403 errors because there are too many attempted connections being made to the webservice. If this is the case how do I get around it? I've tried creating a new instance of InternalWebService each time and disposing of the old one but I get the same problem. I've disabled the firewall and the webservice is located locally at the moment. I beginning to think it may be a problem with the credentials but the control tree is populated via the webservice at some stage. If I browse to the webmethods in my browser I can run them all. I return an instance of the webservice from my login handler loginsession.cs: static LoginSession() { ... g_NavigatorWebService = new InternalWebService(); g_NavigatorWebService.Credentials = System.Net.CredentialCache.DefaultCredentials; ... } public static InternalWebService NavigatorWebService { get { return g_NavigatorWebService; } } I have a tree view control which uses the webservice to populate itself. IncidentTreeViewControl.cs: public IncidentTreeView() { InitializeComponent(); m_WebService = LoginSession.NavigatorWebService; ... } public void Populate() { m_WebService.BeginGetIncidentSummaryByCompany(new AsyncCallback(IncidentSummaryByClientComplete), null); m_WebService.BeginGetIncidentSummaryByDepartment(new AsyncCallback(IncidentSummaryByDepartmentComplete), null); ... } private void IncidentSummaryByClientComplete(IAsyncResult ar) { MyTypedDataSet data = m_WebService.EndGetIncidentSummaryByCompany(ar); //403 ..cont... } I'm getting the 403 on the last line.

• Custom CheckBoxList in ASP.NET

  - by Rick

  Since ASP.NET's CheckBoxList control does not allow itself to be validated with one of the standard validation controls (i.e., RequiredFieldValidator), I would like to create a UserControl that I can use in my project whenever I need a checkbox list that requires one or more boxes to be checked. The standard CheckBoxList can be dragged onto a page, and then you can manually add <asp:ListItem> controls if you want. Is there any way I can create a UserControl that lets me manually (in the markup, not programmatically) insert ListItems from my page in a similar manner? In other words, can I insert a UserControl onto a page, and then from the Designer view of the Page (i.e., not the designer view of the UserControl), can I manually add my ListItems like so: <uc1:RequiredCheckBoxList> <asp:ListItem Text="A" value="B"></asp:ListItem> <asp:ListItem Text="X" value="Y"></asp:ListItem> </uc1:RequiredCheckBoxList> If a UserControl is not the appropriate choice for the end result I'm looking for, I'm open to other suggestions. Please note that I am aware of the CustomValidator control (which is how I plan to validate within my UserControl). It's just a pain to write the same basic code each time I need one of these required checkbox lists, which is why I want to create a re-usable control.

• C# WPF XAML Problem with icon in GridViewColumn

  - by Alex

  I've created a ListView with a GridView component in it. Now trying to fill one of the cells with an icon (PNG) like in the code sample below (save_icon.png): <ListView.View> <GridView> <GridViewColumn Header="Date" Width="Auto" DisplayMemberBinding="{Binding Date}" /> <GridViewColumn Header="Time" Width="Auto" DisplayMemberBinding="{Binding Time}" /> <GridViewColumn Header="FriendlyName" Width="Auto" DisplayMemberBinding="{Binding FriendlyName}" /> <GridViewColumn Width="Auto"> <Image Source="save_icon.png" /> </GridViewColumn> </GridView> </ListView.View> Visual Studio gives me an error on the line, where i put the icon into the column (ERROR: "Error 35: The file save_icon.png is not part of the project or its 'Build Action' property is not set to 'Resource'.") I added the icon to the project as a resource and when i start the app, everything works (the icon appears at the right place). But the WPF designer window can't be reloaded and i'm not able to see changes in the designer, when i change the XAML code. Can somebody explain this error or am i doing something wrong? Thanks for every hint in advance!

• c# (wcf) architecture file and directory structure (and instantiation)

  - by stevenrosscampbell

  Hello and thanks for any assistance. I have a wcf service that I'm trying to properly modularize. I'm interested in finding out if there is a better way or implementing the file and directory structure along with instanciatation, is there a more appropriate way of abstraction that I may be missing? Is this the best approach? especially if performance and the ability to handle thousands of simultanious request? Currently I have this following structure: -Root\Service.cs public class Service : IService { public void CreateCustomer(Customer customer) { CustomerService customerService = new CustomerService(); customerService.Create(customer); } public void UpdateCustomer(Customer customer) { CustomerService customerService = new CustomerService(); customerService.Update(customer); } } -Root\Customer\CustomerService.cs pulbic class CustomerService { public void Create(Customer customer) { //DO SOMETHING } public void Update(Customer customer) { //DO SOMETHING } public void Delete(int customerId) { //DO SOMETHING } public Customer Retrieve(int customerId) { //DO SOMETHING } } Note: I do not include the Customer Object or the DataAccess libraries in this example as I am only concerned about the service. If you could either let me know what you think, if you know a better way, or a resource that could help out. Thanks Kindly. Steven

• Why user control with code behind file doesn't want to compile under MVC2?

  - by kyrisu

  I have user control in my MVC2 app placed in the Content folder (it's not supposed to be a view, just reusable part of the app). UserControl1.ascx looks like: <@ Control AutoEventWireup="true" Language="C#" CodeFile="~/Content/UserControl1.ascx.cs" Inherits="MVCDrill.Content.UserControl1" %> <div runat="server" id="mydiv"> <asp:LinkButton id="lb_text" runat="server"></asp:LinkButton> </div> UserControl1.ascx.cs looks like: using System; using System.Web; using System.Web.UI; namespace MVCDrill.Content { public class UserControl1 : UserControl { public string Text { get { return this.lb_text.Text; } set { this.lb_text.Text = value; } } } } I'm pretty sure this kind of stuff compiled under webforms but I'm getting compilation error: 'MVCDrill.Content.UserControl1' does not contain a definition for 'lb_text' and no extension method 'lb_text' accepting a first argument of type 'MVCDrill.Content.UserControl1' could be found (are you missing a using directive or an assembly reference?) Am I missing something? How to change it (what is the alternative) in MVC2 ? p.s. Intellisense sees lb_text with no problem. I've tried with different controls with the same outcome.

• LINQ Datacontext Disposal Issues

  - by Refracted Paladin

  I am getting a Cannot access object: DataContext after it's been disposed in the below DAL method. I thought that I would be okay calling dispose there. result is an IEnumurable and I thought it was IQueryable that caused these kinds of problems. What am I doing wrong? How SHOULD I be disposing of my DataContext. Is there something better to be returning then a DataTable? This is a Desktop app that points at SQL 2005. Example method that causes this error -- public static DataTable GetEnrolledMembers(Guid workerID) { var DB = CmoDataContext.Create(); var AllEnrollees = from enrollment in DB.tblCMOEnrollments where enrollment.CMOSocialWorkerID == workerID || enrollment.CMONurseID == workerID join supportWorker in DB.tblSupportWorkers on enrollment.EconomicSupportWorkerID equals supportWorker.SupportWorkerID into workerGroup from worker in workerGroup.DefaultIfEmpty() select new { enrollment.ClientID, enrollment.CMONurseID, enrollment.CMOSocialWorkerID, enrollment.EnrollmentDate, enrollment.DisenrollmentDate, ESFirstName = worker.FirstName, ESLastName = worker.LastName, ESPhone = worker.Phone }; var result = from enrollee in AllEnrollees.AsEnumerable() where (enrollee.DisenrollmentDate == null || enrollee.DisenrollmentDate > DateTime.Now) //let memberName = BLLConnect.MemberName(enrollee.ClientID) let lastName = BLLConnect.MemberLastName(enrollee.ClientID) let firstName = BLLConnect.MemberFirstName(enrollee.ClientID) orderby enrollee.DisenrollmentDate ascending, lastName ascending select new { enrollee.ClientID, //MemberName = memberName, LastName = lastName, FirstName = firstName, NurseName = BLLAspnetdb.NurseName(enrollee.CMONurseID), SocialWorkerName = BLLAspnetdb.SocialWorkerName(enrollee.CMOSocialWorkerID), enrollee.EnrollmentDate, enrollee.DisenrollmentDate, ESWorkerName = enrollee.ESFirstName + " " + enrollee.ESLastName, enrollee.ESPhone }; DB.Dispose(); return result.CopyLinqToDataTable(); } partial class where I create the DataContext -- partial class CmoDataContext { public static bool IsDisconnectedUser { get { return Settings.Default.IsDisconnectedUser; } } public static CmoDataContext Create() { var cs = IsDisconnectedUser ?

• AContext.data can be nil?

  - by waza123

  In this code, as you see on Connect, AContext.Data is filled with something TmyTThreadList = class(TThreadList) id: integer; end; var unique_id:integer; procedure TfrmTestIdTCPServer.IdTCPServerConnect(AContext: TIdContext); begin CS.Enter; try inc(unique_id); finally CS.Leave; end; AContext.Data := myTThreadList.Create; list := myTThreadList(AContext.Data).LockList; try myTThreadList(AContext.Data).id := my_unique_id; list.Add(myTThreadList(AContext.Data)); finally myTThreadList(AContext.Data).UnlockList; end; end; then on disconnect, coder is checking here for Acontext.Data < nil procedure TfrmTestIdTCPServer.IdTCPServerDisconnect(AContext: TIdContext); var begin if AContext.Data <> nil then begin The question is, why he is checking for nil ? Thanks. EDIT: I'm asking this, because when I do the same, onExecute I access AContext.Data , and sometimes (when in same time is connecting many clients) AContext.Data is empty, access violation appears.

• jQuery ajax call doesn't seem to do anything at all

  - by icemanind

  I am having a problem with making an ajax call in jQuery. Having done this a million times, I know I am missing something really silly here. Here is my javascript code for making the ajax call: function editEmployee(id) { $('#<%= imgNewEmployeeWait.ClientID %>').hide(); $('#divAddNewEmployeeDialog input[type=text]').val(''); $('#divAddNewEmployeeDialog select option:first-child').attr("selected", "selected"); $('#divAddNewEmployeeDialog').dialog('open'); $('#createEditEmployeeId').text(id); var inputEmp = {}; inputEmp.id = id; var jsonInputEmp = JSON.stringify(inputEmp); debugger; alert('Before Ajax Call!'); $.ajax({ type: "POST", url: "Configuration.aspx/GetEmployee", data: jsonInputEmp, contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { alert('success'); }, error: function (msg) { alert('failure'); } }); } Here is my CS code that is trying to be called: [WebMethod] public static string GetEmployee(int id) { var employee = new Employee(id); return Newtonsoft.Json.JsonConvert.SerializeObject(employee, Newtonsoft.Json.Formatting.Indented); } When I try to run this, I do get the alert that says Before Ajax Call!. However, I never get an alert back that says success or an alert that says failure. I did go into my CS code and put a breakpoint on the GetEmployee method. The breakpoint did hit, so I know jQuery is successfully calling the method. I stepped through the method and it executed just fine with no errors. I can only assume the error is happening when the jQuery ajax call is returning from the call. Also, I looked in my event logs just to make sure there wasn't an ASPX error occurring. There is no error in the logs. I also looked at the console. There are no script errors. Anyone have any ideas what I am missing here? `

• How can I stop an auto-generated Linq to SQL class from loading ALL data?

  - by Gary McGill

  DUPLICATE of http://stackoverflow.com/questions/2433422/how-can-i-stop-an-auto-generated-linq-to-sql-class-from-loading-all-data post answers there! I have an ASP.NET MVC project, much like the NerdDinner tutorial example. (I'm using MVC 2, but followed the NerdDinner tutorial in order to create it). As per the instructions in part 3 of the tutorial, I've created a Linq-to-SQL model of my database by creating a "Linq to SQL Classes" (.dbml) surface, and dropping my database tables onto it. The designer has automatically added relationships between the generated classes based on my database tables. Let's say that my classes are as per the NerdDinner example, so I have Dinner and RSVP tables, where each Dinner record is associated with many RSVP records - hence in the generated classes, the Dinner object has a RSVPs property which is a list of RSVP objects. My problem is this: it appears (and I'd be gladly proved wrong on this) that as soon as I access a Dinner object, it's loading all of the corresponding RSVP objects, even if I don't use the RSVPs member. First question: is this really the default behavior for the generated classes? In my particular situation, the object graph contains many more tables (which have an order of magnitude more records), and so this is disastrous behaviour - I'd be loading tons of data when all I want to do is show the details of a single parent record. Second question: are there any properties exposed through the designer UI that would let me modify this behavior? (I can't find any). Third question: I've seen a description of how to control the loading of related records in a DataContext by using a DataShape object associated with the DataContext. Is that what I'm meant to do, and if so are there any tutorials like the NerdDinner one that would show not only how to do it, but also suggest a 'pattern' for normal use?

• d:DesignData issue, Visual Studio 2010 cant build after adding sample design data with Expression Bl

  - by Valko

  Hi, VS 2010 solution and Silverlight project builds fine, then: I open MyView.xaml view in Expression Blend 4 Add sample data from class (I use my class defined in the same project) after I add new sample design data with Expression blend 4, everything looks fine, you see the added sample data in the EB 4 fine, you also see the data in VS 2010 designer too. Close the EB 4, and next VS 2010 build is giving me this errors: Error 7 XAML Namespace http://schemas.microsoft.com/expression/blend/2008 is not resolved. C:\Code\source\...myview.xaml and: Error 12 Object reference not set to an instance of an object. ... TestSampleData.xaml when I open the TestSampleData.xaml I see that namespace for my class used to define sample data is not recognized. However this namespace and the class itself exist in the same project! If I remove the design data from the MyView.xaml: d:DataContext="{d:DesignData /SampleData/TestSampleData.xaml}" it builds fine and the namespace in TestSampleData.xaml is recognized this time?? and then if add: d:DataContext="{d:DesignData /SampleData/TestSampleData.xaml}" I again see in the VS 2010 designer sample data, but the next build fails and again I see studio cant find the namespace in my TestSampleData.xaml containing sample data. That cycle is driving me crazy. Am I missing something here, is it not possible to have your class defining sample design data in the same project you have the MyView.xaml view?? cheers Valko

• Investigating the root cause behind SharePoint's "request not found in the TrackedRequests"

  - by Muhimbi

  We have a long standing issue in our bug tracking system about the dreaded "ERROR: request not found in the TrackedRequests. We might be creating and closing webs on different threads." message in SharePoint's trace log. As we develop Workflow software for the SharePoint market, we look into this issue from time to time to make sure it is not caused by our products. I have personally come to the conclusion that this is a problem in SharePoint, but perhaps someone else can prove me wrong. Here is what I know: According to the hundreds of search results returned by Google on this topic, this issue appears to be mainly related to SharePoint Workflows, both SharePoint Designer and Visual Studio based workflows. Assuming ULS logging is set to Monitorable, the easiest way to reproduce this problem is to create a new SharePoint Designer Workflow, attach it to a document library, set it to auto start on add/update, don't add any actions, save the workflow and upload a file to the document library. The error is only visible in the SharePoint trace log, it does not appear to impact the execution of the workflow at hand. I have verified that the problem occurs on 32 bit as well as 64 bit systems, Win2K3 and 2K8, WSS and MOSS with SharePoint versions up to the December 2009 Cumulative Update (6524). The problem does not occur when a workflow is started manually. There are dozens of related posts on MSDN Forums, hundreds on Google, one on StackOverflow and none on SharePoint Overflow. There appears to be no answer. Does anyone have any idea about what is going on, what is causing this and if we should worry or file this under 'Red Herrings'.

• Properly changing Ajax MultiHandle Slider parameters on postbacks

  - by Matthew PK

  Hi all, In VS2010 I have VB.NET codebehind aspx pages and I'm using Ajax multihandleslider extensions to filter search results on numerical values. Fistly, the multihandle sliders don't display in the designer... I have to remove the slider targets tag: In order to make it display in the designer... this isn't so much a big issue but an annoyance. I am displaying items in a given category. So I get the max and min prices for all items in that category and assign the sliderextension max/min values appropriately. This works fine until... I change the item category and go get a new max/min value for the slider control. I set the max/min values, then I set the target textbox values each to the corresponding max/min values. The slider handles don't repaint (or init?) properly Like say for example my initial min/max is 1/100 if I do a full postback and change the max value to 1000 then the slider bar (correctly) stays the same size but the handle appears WAYYYY to the right off the page and I have to scroll to it. When I click it, it shoots back onto the slider bar. I'm pulling my hair out... why do the slider handles only appear properly when I first set the min/max values?

• How to access a method on a generic datacontext which is only created at runtime

  - by Jeremy Holt

  I'm creating my generic DataContext using only the connectionString in the ctor. I have no issues in retrieving the table using DataContext.GetTable(). However, I need to also be able to retrieve entities of inline table functions. The dbml designer generates public IQueryable<testFunctionResult> testFunction() { return this.CreateMethodCallQuery<testFunctionResult>(this, ((MethodInfo)(MethodInfo.GetCurrentMethod()))); } The question is how do I get the MethodInfo.GetCurrentMethod() when the DataContext has no method called "testFunction", i.e.typeof(DataContext).GetMethod("testFunction") returns null? What I'm trying to achieve is something like: public class UnitofWork<T> { public UnitofWork(string connectionString) { this.DataContext = new DataContext(connectionString); } public UnitofWork(IQueryable<T> tableEntity) { _tableEntity = tableEntity; } public IQueryable<T> TableEntity { get { if (DataContext == null) return _tableEntity; var metaType = DataContext.Mapping.GetMetaType(typeof (T)); if (metaType.IsEntity) _tableEntity = DataContext.GetTable<T>(); else { var s = typeof(T).Name; string methodName = s.Substring(0, s.IndexOf("Result")) + "()"; // the designer automatically affixes "Result" to the type name // Make a method from methodName // _tableEntity = DataContext.CreateMethodCallQuery(DataContext, method, new object[]{}); } return _tableEntity; } set { _tableEntity = value; } } ) Thanks in advance for any insight Jeremy

• Set Server Side OnClick() event Programmatically

  - by Corey O.

  I am looking for a way to programmatically set the OnClick event handler for a TableCell object. The ASP equivalent of what I'm trying to do will look like this: <asp:TableCell OnClick="clickHandler" runat="server">Click Me!</asp:TableCell> In the above example, "clickHandler" is a server-side function defined in the .cs CodeBehind. public virtual void clickHandler(object sender, EventArgs args) {...} However, for my situation, this TableCell object needs to be created dynamically, so setting it in an ASP tag is not an option. I am trying to do something like the following in the CodeBehind: System.Web.UI.WebControls.TableRow row = new System.Web.UI.WebControls.TableRow(); System.Web.UI.WebControls.TableCell cell = new System.Web.UI.WebControls.TableCell(); cell.Text = "Click Me!"; cell.Attributes.Add("onClick", "clickHandler"); row.Cells.Add(cell); Unfortunately, in this situation: cell.Attributes.Add("onClick", "clickHandler"); the "clickHandler" only works as a client-side javascript function. What I'm looking for is a way to link the server-side clickHandler() function, defined in the .cs CodeBehind, to this table cell. After an afternoon of searching, I have been unable to come up with a working solution. Thanks in advance for any help.

• Explaining the need to avoid horizontal scroll

  - by Bradley Herman

  I need help explaining to my boss why her design is poor on a client's website. She has no knowledge of the web, and it can be difficult as a web developer working with a woman who is a graphic designer (not even a web designer really). On a current site she has designed, an image bar "needs" to be ~1200px according to her, though it isn't necessary with the content. A quick sketch to illustrate what's going on: As you see, the banner spills out past the 960px of the content and as wide as 1200px. This creates a horizontal scroll when all the content is viewable within the 960px wide viewport. I need to make this an <img and not a CSS background because it's a jQuery slideshow that fades from image to image. I think this is a big problem because a lot of people are going to get a horizontal scroll bar imposed in their browser when they're still able to see all the relevant content. She thinks no one will notice and it'll be fine; I think it's very bad practice and confusing to the end user. How do I explain the problem to her?

• Strange behaviour using Drag and Drop in word 2003 automation in headers

  - by Oliver Hanappi

  Hi! I am developing a template based addin for Word 2003 which allows the user to drag and drop elements from a listbox into the word document. Unfortunately I'm getting a really strange behaviour when trying to drop elements in the document's header. Open the template and type something in the header Close the header and insert some content on the page Add a page break. Switch to page layout mode where and set zoom level to "Two Pages" Open the header Slowly Drag and Drop an list item from the list box to the header. See multiple Page Setups dialogs occur which cause Word to crash. Here is my code: // in ThisDocument.cs public MyUserControl _control; public void Init() { _control = new MyUserControl(); ActionsPane.Controls.Add(_control); ActionsPane.Visible = true; } // in MyUserControl.cs public void listBox1_MouseDown(object sender, MouseEventArgs e) { DoDragDrop("something", DragDropEffects.Copy); } Have I done somethinkg wrong with implementing Drag and Drop? Is there a workaround for this strange behaviour? Thanks in advance, Oliver Hanappi

• How to use delegate to perform callback between caller and web service helper class?

  - by codemonkie

  I have 2 classes A and B, where they belongs to the same namespace but resides in seperate files namely a.cs and b.cs, where class B essentially is a helper wrapping a web service call as follow: public class A { public A() // constructor { protected static B b = new B(); } private void processResult1(string result) { // come here when result is successful } private void processResult2(string result) { // come here when result is failed } static void main() { b.DoJobHelper(...); } } public class B { private com.nowhere.somewebservice ws; public B() { this.ws = new com.nowhere.somewebservice(); ws.JobCompleted += new JobCompletedEventHandler(OnCompleted); } void OnCompleted(object sender, JobCompletedEventArgs e) { string s = e.Result; Guid taskID = (Guid)e.UserState; switch (s) { case "Success": // Call processResult1(); break; case "Failed": // Call processResult2(); break; default: break; } } public void DoJobHelper() { Object userState = Guid.NewGuid(); ws.DoJob(..., userState); } } (1) I have seen texts on the net on using delegates for callbacks but failed to apply that to my case. All I want to do is to call the appropriate processResult() method upon OnCompleted() event, but dunno how to and where to declare the delegate: public delegate void CallBack(string s); (2) There is a sender object passed in to OnCompleted() but never used, did I miss anything there? Or how can I make good use of sender? Any helps appreciated.
