  • ASP.Net master page scrollbar question

    - by Stephen Falken
    Like happens to all of us sometimes, I inherited some crappy code I have to fix. We need to center our pages on widescreen machines, so we have a master page layout div like so: .MasterLayout { width:1100px; height: 100%; position:absolute; left:50%; margin-left:-550px; vertical-align:top; } I removed most of the detailed attributes for readability here, but here's how the table for the master page is laid out: <table border="0" cellpadding="0" cellspacing="0" style="width: 100%;"> <tr> <td style="width: 100%" align="center" colspan="2"> </td> </tr> <tr> <td colspan="2" style="height: 20px; background-color: #333;"> <asp:SiteMapPath/> </td> </tr> <tr> <td style="width: 86px; height: 650px; background-color: #B5C7DE; margin: 6px;" valign="top"> <asp:Menu /> <asp:SiteMapDataSource /> </td> <td style="background-color:#ffffff; margin:5px; width:1000px;" valign="top"> <asp:contentplaceholder id="ContentPlaceHolder1" runat="server"/> </td> </tr> </table> When resizing the browser window, the horizontal scrollbar only reaches as far as the left edge of the <asp:contentplaceholder/> control, and the <asp:menu/> that's in the 86px wide <td> is hidden. How can I fix this problem? THANKS IN ADVANCE

  • Uses of a C++ Arithmetic Promotion Header

    - by OlduvaiHand
    I've been playing around with a set of templates for determining the correct promotion type given two primitive types in C++. The idea is that if you define a custom numeric template, you could use these to determine the return type of, say, the operator+ function based on the class passed to the templates. For example: // Custom numeric class template <class T> struct Complex { Complex(T real, T imag) : r(real), i(imag) {} T r, i; // Other implementation stuff }; // Generic arithmetic promotion template template <class T, class U> struct ArithmeticPromotion { typedef typename X type; // I realize this is incorrect, but the point is it would // figure out what X would be via trait testing, etc }; // Specialization of arithmetic promotion template template <> class ArithmeticPromotion<long long, unsigned long> { typedef typename unsigned long long type; } // Arithmetic promotion template actually being used template <class T, class U> Complex<typename ArithmeticPromotion<T, U>::type> operator+ (Complex<T>& lhs, Complex<U>& rhs) { return Complex<typename ArithmeticPromotion<T, U>::type>(lhs.r + rhs.r, lhs.i + rhs.i); } If you use these promotion templates, you can more or less treat your user defined types as if they're primitives with the same promotion rules being applied to them. So, I guess the question I have is would this be something that could be useful? And if so, what sorts of common tasks would you want templated out for ease of use? I'm working on the assumption that just having the promotion templates alone would be insufficient for practical adoption. Incidentally, Boost has something similar in its math/tools/promotion header, but it's really more for getting values ready to be passed to the standard C math functions (that expect either 2 ints or 2 doubles) and bypasses all of the integral types. Is something that simple preferable to having complete control over how your objects are being converted? TL;DR: What sorts of helper templates would you expect to find in an arithmetic promotion header beyond the machinery that does the promotion itself?

  • Button.MouseDown

    - by Gilad
    Hi Guys, I'm relatively new with WPF. I'm trying to understand the difference between MouseDownEvent and PreviewMouseDownEvent. I understand the WPF event strategies and i understand that the MouseDown event is a bubbling event and the PreviewMouseDown is a tunneling event. I also understand the order of which these events are being fired - according to this MSDN overview http://msdn.microsoft.com/en-us/library/ms742806.aspx#routing (there is a diagram with example there). So i tried to code some my self, check this for example: <Grid x:Name="grid" Width="250"> <StackPanel Mouse.MouseDown="StackPanel_MouseDown" PreviewMouseDown="StackPanel_PreviewMouseDown"> <WPFVisualizerExample:MyButton x:Name="B1" PreviewMouseDown="B1_PreviewMouseDown" MouseDown="B1_MouseDown" Margin="5,5,5,5"> <WPFVisualizerExample:MyButton x:Name="B2" PreviewMouseDown="B2_PreviewMouseDown" MouseDown="B2_MouseDown" Margin="5,5,5,5"> <WPFVisualizerExample:MyButton x:Name="B3" PreviewMouseDown="B3_PreviewMouseDown" MouseDown="B3_MouseDown" Margin="5,5,5,5">Click Me</WPFVisualizerExample:MyButton> </WPFVisualizerExample:MyButton> </WPFVisualizerExample:MyButton> </StackPanel> </Grid> I have an event handler for each of the events (the preview and non-preview) and i wanted to see what is happening, which of the event is being thrown (i have a message box shown for each event). The 'MyButton' user control simply extends the base Button and override the OnMouseDown and OnPreviewMouseDown to set the e.Handled false: protected override void OnMouseDown(System.Windows.Input.MouseButtonEventArgs e) { base.OnMouseDown(e); e.Handled = false; } protected override void OnPreviewMouseDown(System.Windows.Input.MouseButtonEventArgs e) { base.OnPreviewMouseDown(e); e.Handled = false; } (tried with this and without this). According to the MSDN overview (in the link above), if i have 3 elements then the events route should be as follows: PreviewMouseDown (tunnel) on root element. PreviewMouseDown (tunnel) on intermediate element #1. PreviewMouseDown (tunnel) on source element #2. MouseDown (bubble) on source element #2. MouseDown (bubble) on intermediate element #1. MouseDown (bubble) on root element. So I expected the the message boxes to be shown according to the above. From some reason - which I don't understand only the preview events are being thrown (according to what the MSDN says Preview_B1=Preview_B2=Preview_B3). My expectations were: Preview_B1=Preview_B2=Preview_B3=NonPreview_B3=NonPreview_B2=NonPreview_B1. But the non-preview events are not being thrown at all. So basically I don't understand the route of the events, from MSDN overview I understood that the route starts from the root element, goes down (tunnel) to the source element and then back up (bubble) to the root element, but this is not what happening in practice. It is really important for me to understand how this events are working, i probably miss-understand something basic here, your help will be appreciated. THANX!! -Gili

  • Why am I seeing a crash when trying to call CDHtmlDialog::OnInitDialog()

    - by Tim
    I added a helpAbout menu item to my mfc app. I decided to make the ddlg derive from CDHTMLDialog. I override the OnInitDialog() method in my derived class and the first thing I do is call the parent's OnInitDialog() method. I then put in code that sets the title. On some machines this works fine, but on others it crashes in the call to CDHtmlDialog::OnInitDialog() - Trying to read a null pointer. the call stack has nothing useful - it is in mfc90.dll Is this a potential problem with mismatches of mfc/win32 dlls? It works on my vista machines but crashes on a win2003 server box. BOOL HTMLAboutDlg::OnInitDialog() { // CRASHES on the following line CDHtmlDialog::OnInitDialog(); CString title = "my title"; // example of setting title // i try to get version info //set the title CModuleVersion ver; char filename[ _MAX_PATH ]; GetModuleFileName( AfxGetApp()->m_hInstance, filename, _MAX_PATH ); ver.GetFileVersionInfo(filename); // get version from VS_FIXEDFILEINFO struct CString s; s.Format("Version: %d.%d.%d.%d\n", HIWORD(ver.dwFileVersionMS), LOWORD(ver.dwFileVersionMS), HIWORD(ver.dwFileVersionLS), LOWORD(ver.dwFileVersionLS)); CString version = ver.GetValue(_T("ProductVersion")); version.Remove(' '); version.Replace(",", "."); title = "MyApp - Version " + version; SetWindowText(title); return TRUE; // return TRUE unless you set the focus to a control } And here is the relevant header file: class HTMLAboutDlg : public CDHtmlDialog { DECLARE_DYNCREATE(HTMLAboutDlg) public: HTMLAboutDlg(CWnd* pParent = NULL); // standard constructor virtual ~HTMLAboutDlg(); // Overrides HRESULT OnButtonOK(IHTMLElement *pElement); HRESULT OnButtonCancel(IHTMLElement *pElement); // Dialog Data enum { IDD = IDD_DIALOG_ABOUT, IDH = IDR_HTML_HTMLABOUTDLG }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support virtual BOOL OnInitDialog(); DECLARE_MESSAGE_MAP() DECLARE_DHTML_EVENT_MAP() }; I can't figure out what is going on - why it works on some machins and crashes on others. Both have VS2008 installed EDIT: VS versions VISTA - no crashes 9.0.30729.1 SP 2003 server: (crashes) 9.0.21022.8 RTM

  • How to merge an improperly created "branch" that isn't really a branch (wasn't created by an svn cop

    - by MatrixFrog
    I'm working on a team with lots of people who are pretty unfamiliar with the concepts of version control systems, and are just kind of doing whatever seems to work, by trial and error. Someone created a "branch" from the trunk that is not ancestrally related to the trunk. My guess is it went something like this: They created a folder in branches. They checked out all the code from the trunk to somewhere on their desktop. They added all that code to the newly created folder as though it was a bunch of brand new files. So the repository isn't aware that all that code is actually just a copy of the trunk. When I look at the history of that branch in TortoiseSVN, and uncheck the "Stop on copy/rename" box, there is no revision that has the trunk (or any other path) under the "Copy from path" column. Then they made lots of changes on their "branch". Meanwhile, others were making lots of changes on the trunk. We tried to do a merge and of course it doesn't work. Because, the trunk and the fake branch are not ancestrally related. I can see only two ways to resolve this: Go through the logs on the "branch", look at every change that was made, and manually apply each change to the trunk. Go through the logs on the trunk, look at every change that was made between revision 540 (when the "branch" was created) and HEAD, and manually apply each change to the "branch". This involves 7 revisions one way or 11 revisions the other way, so neither one is really that terrible. But is there any way to cause the repository to "realize" that the branch really IS ancestrally related even though it was created incorrectly, so that we can take advantage of the built-in merging functionality in Eclipse/TortoiseSVN? (You may be wondering: Why did your company hire these people and allow them to access the SVN repository without making sure they knew how to use it properly first?! We didn't -- this is a school assignment, which is a collaboration between two different classes -- the ones in the lower class were given a very quick hand-wavey "overview" of SVN which didn't really teach them anything. I've asked everyone in the group to please PLEASE read the svn book, and I'll make sure we (the slightly more experienced half of the team) keep a close eye on the repository to ensure this doesn't happen again.)

  • How can I call VC# webservice methods without ArgumentException?

    - by Zarius
    Currently, I'm trying to write a small tray application that will show the status and provide control of a server-side application exposed over webservice. The webservice only has 3 operations: start, stop and status. When I call any of these operations in code, they throw an ArgumentException citing "An item with the same key has already been added". I am compiling the webservice on Visual C# Express 2008, and .NET 3.5. The Code: private TelnetConnClient Conn { get { return new TelnetConnClient(); } } private bool Connected //call webservice operations { get { return Conn.Status(); } set { if(value) Conn.Start(); else Conn.Stop(); } } The Stacktrace: A first chance exception of type 'System.ArgumentException' occurred in mscorlib.dll at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) at System.ServiceModel.TransactionFlowAttribute.ApplyBehavior(OperationDescription description, BindingParameterCollection parameters) at System.ServiceModel.TransactionFlowAttribute.System.ServiceModel.Description.IOperationBehavior.AddBindingParameters(OperationDescription description, BindingParameterCollection parameters) at System.ServiceModel.Description.DispatcherBuilder.AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection parameters) at System.ServiceModel.Description.DispatcherBuilder.BuildProxyBehavior(ServiceEndpoint serviceEndpoint, BindingParameterCollection& parameters) at System.ServiceModel.Channels.ServiceChannelFactory.BuildChannelFactory(ServiceEndpoint serviceEndpoint) at System.ServiceModel.ChannelFactory.CreateFactory() at System.ServiceModel.ChannelFactory.OnOpening() at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.ChannelFactory.EnsureOpened() at System.ServiceModel.ChannelFactory`1.CreateChannel(EndpointAddress address, Uri via) at System.ServiceModel.ChannelFactory`1.CreateChannel() at System.ServiceModel.ClientBase`1.CreateChannel() at System.ServiceModel.ClientBase`1.CreateChannelInternal() at System.ServiceModel.ClientBase`1.get_Channel() at KordiaConnect.ferries.TelnetConnClient.Start() in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Service References\ferries\Reference.cs:line 86 at coldshark.ferries.Main.set_Connected(Boolean value) in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 22 at coldshark.ferries.Main.<.ctor>b__0(Object sender, EventArgs e) in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 43 at System.Windows.Forms.NotifyIcon.OnClick(EventArgs e) at System.Windows.Forms.NotifyIcon.WmMouseUp(Message& m, MouseButtons button) at System.Windows.Forms.NotifyIcon.WndProc(Message& msg) at System.Windows.Forms.NotifyIcon.NotifyIconNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.PeekMessage(MSG& msg, HandleRef hwnd, Int32 msgMin, Int32 msgMax, Int32 remove) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run() at coldshark.ferries.Main..ctor() in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 55 I can just call the webservice from the web interface, but this application will give me a handy status notification icon, and I'd really love to know why the out-of-the-box auto-generated code fails for no particular reason.

  • should I ever put a major version number into a C#/Java namespace?

    - by Andrew Patterson
    I am designing a set of 'service' layer objects (data objects and interface definitions) for a WCF web service (that will be consumed by third party clients i.e. not in-house, so outside my direct control). I know that I am not going to get the interface definition exactly right - and am wanting to prepare for the time when I know that I will have to introduce a breaking set of new data objects. However, the reality of the world I am in is that I will also need to run my first version simultaneously for quite a while. The first version of my service will have URL of http://host/app/v1service.svc and when the times comes by new version will live at http://host/app/v2service.svc However, when it comes to the data objects and interfaces, I am toying with putting the 'major' version of the interface number into the actual namespace of the classes. namespace Company.Product.V1 { [DataContract(Namespace = "company-product-v1")] public class Widget { [DataMember] string widgetName; } public interface IFunction { Widget GetWidgetData(int code); } } When the time comes for a fundamental change to the service, I will introduce some classes like namespace Company.Product.V2 { [DataContract(Namespace = "company-product-v2")] public class Widget { [DataMember] int widgetCode; [DataMember] int widgetExpiry; } public interface IFunction { Widget GetWidgetData(int code); } } The advantages as I see it are that I will be able to have a single set of code serving both interface versions, sharing functionality where possible. This is because I will be able to reference both interface versions as a distinct set of C# objects. Similarly, clients may use both interface versions simultaneously, perhaps using V1.Widget in some legacy code whilst new bits move on to V2.Widget. Can anyone tell why this is a stupid idea? I have a nagging feeling that this is a bit smelly.. notes: I am obviously not proposing every single new version of the service would be in a new namespace. Presumably I will do as many non-breaking interface changes as possible, but I know that I will hit a point where all the data modelling will probably need a significant rewrite. I understand assembly versioning etc but I think this question is tangential to that type of versioning. But I could be wrong.

  • one page over 9 different urls

    - by Ali Demirtas
    Hi I am using prestashop as the cart for my website. I have a problem; the website used to be in dynamic urls. I enabled friendly url writing. The problem is that one page has more than one url. You can access a same page from the dynamic url and static url. In fact a single page has 9 different urls. This obviously creates problems for seo as search engines penalize my website for this. Here are examples of a page with more than 2 urls (http://www.turkishfootballstore.com/lang-nl/product.php?id_product=515) (http://www.turkishfootballstore.com/fenerbahce/515-fenerbahce-thuisshirt-20092010.html) (http://www.turkishfootballstore.com/lang-nl/fenerbahce/515-fenerbahce-thuisshirt-20092010.html) you can see even the static url's have 2 one with language defined and the other without. out fo the three urls above the correct one is the one at the bottom. What can I do to solve this problem? I have no knowledge of programming. Here is the htaccess for the website. Any sample code or help is really appreciated. There is 550 pages and every page is published in 17 different languages I want to use a 301 auto redirect. What is the simplest way to do it? I have no idea of coding. # URL rewriting module activation RewriteEngine on # URL rewriting rules RewriteRule ^([a-z0-9]+)\-([a-z0-9]+)(\-[_a-zA-Z0-9-]*)/([_a-zA-Z0-9-]*)\.jpg$ /img/p/$1-$2$3.jpg [L,E] RewriteRule ^([0-9]+)\-([0-9]+)/([_a-zA-Z0-9-]*)\.jpg$ /img/p/$1-$2.jpg [L,E] RewriteRule ^([0-9]+)(\-[_a-zA-Z0-9-]*)/([_a-zA-Z0-9-]*)\.jpg$ /img/c/$1$2.jpg [L,E] RewriteRule ^lang-([a-z]{2})/([a-zA-Z0-9-]*)/([0-9]+)\-([a-zA-Z0-9-]*)\.html(.*)$ /product.php?id_product=$3&isolang=$1$5 [L,E] RewriteRule ^lang-([a-z]{2})/([0-9]+)\-([a-zA-Z0-9-]*)\.html(.*)$ /product.php?id_product=$2&isolang=$1$4 [L,E] RewriteRule ^lang-([a-z]{2})/([0-9]+)\-([a-zA-Z0-9-]*)(.*)$ /category.php?id_category=$2&isolang=$1 [QSA,L,E] RewriteRule ^([a-zA-Z0-9-]*)/([0-9]+)\-([a-zA-Z0-9-]*)\.html(.*)$ /product.php?id_product=$2$4 [L,E] RewriteRule ^([0-9]+)\-([a-zA-Z0-9-]*)\.html(.*)$ /product.php?id_product=$1$3 [L,E] RewriteRule ^([0-9]+)\-([a-zA-Z0-9-]*)(.*)$ /category.php?id_category=$1 [QSA,L,E] RewriteRule ^content/([0-9]+)\-([a-zA-Z0-9-]*)(.*)$ /cms.php?id_cms=$1 [QSA,L,E] RewriteRule ^([0-9]+)__([a-zA-Z0-9-]*)(.*)$ /supplier.php?id_supplier=$1$3 [QSA,L,E] RewriteRule ^([0-9]+)_([a-zA-Z0-9-]*)(.*)$ /manufacturer.php?id_manufacturer=$1$3 [QSA,L,E] RewriteRule ^lang-([a-z]{2})/(.*)$ /$2?isolang=$1 [QSA,L,E] # Catch 404 errors ErrorDocument 404 /404.php Options +FollowSymLinks RewriteEngine on RewriteCond %{HTTP_HOST} ^***.com [NC] RewriteRule ^(.*)$ http://www.***.com/$1 [L,R=301] Options +FollowSymLinks RewriteEngine on # index.php to / RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*index\.php\ HTTP/ RewriteRule ^(.*)index\.php$ /$1 [R=301,L] Header set Cache-Control: "no-store, no-cache, must-revalidate, pre-check=0, post-check=0, max-age=0"

  • How can I include additional markup within a 'Content' inner property of an ASP.Net WebControl?

    - by GenericTypeTea
    I've searched the site and I cannot find a solution for my problem, so apologies if it's already been answered (I'm sure someone must have asked this before). I have written a jQuery Popup window that I've packaged up as a WebControl and IScriptControl. The last step is to be able to write the markup within the tags of my control. I've used the InnerProperty attribute a few times, but only for including lists of strongly typed classes. Here's my property on the WebControl: [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public something??? Content { get { if (_content == null) { _content = new something???(); } return _content; } } private something??? _content; Here's the HTML Markup of what I'm after: <ctr:WebPopup runat="server" ID="win_Test" Hidden="false" Width="100px" Height="100px" Modal="true" WindowCaption="Test Window" CssClass="window"> <Content> <div style="display:none;"> <asp:Button runat="server" ID="Button1" OnClick="Button1_Click" /> </div> <%--Etc--%> <%--Etc--%> </Content> </ctr:WebPopup> Unfortunately I don't know what type my Content property should be. I basically need to replicate the UpdatePanel's ContentTemplate. EDIT: So the following allows a Template container to be automatically created, but no controls show up, what's wrong with what I'm doing? [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public ITemplate Content { get { return _content; } set { _content = value; } } private ITemplate _content; EDIT2: Overriding the CreateChildControls allows the controls within the ITemplate to be rendered: protected override void CreateChildControls() { if (this.Content != null) { this.Controls.Clear(); this.Content.InstantiateIn(this); } base.CreateChildControls(); } Unfortunately I cannot now access the controls within the ITemplate from the codebehind file on the file. I.e. if I put a button within my mark as so: <ctr:WebPopup runat="server" ID="win_StatusFilter"> <Content> <asp:Button runat="server" ID="btn_Test" Text="Cannot access this from code behind?" /> </Content> </ctr:WebPopup> I then cannot access btn_Test from the code behind: protected void Page_Load(object sender, EventArgs e) { btn_Test.Text = "btn_Test is not present in Intellisense and is not accessible to the page. It does, however, render correctly."; }

  • how to read values from the remote OPC Server

    - by Shailesh Jaiswal
    I have created one asp.net web service. In this web service I am using the web method as follows. The web service is related to the OPC ( OLE for process control) public string ReadServerItems(string ServerName) { string txt = ""; ArrayList obj = new ArrayList(); XmlServer Srv = new XmlServer("XDAGW.CS.WCF.Eval.1"); RequestOptions opt = new RequestOptions(); ReadRequestItemList iList = new ReadRequestItemList(); iList.Items = new ReadRequestItem[3]; iList.Items[0] = new ReadRequestItem(); iList.Items[0].ItemName = "ServerInfo.ConnectedClients"; iList.Items[1] = new ReadRequestItem(); iList.Items[1].ItemName = "ServerInfo.TotalGroups"; iList.Items[2] = new ReadRequestItem(); iList.Items[2].ItemName = "EventSources.Area1.Tracking"; ReplyItemList rslt; OPCError[] err; ReplyBase reply = Srv.Read(opt, iList, out rslt, out err); if ((rslt == null)) txt += err[0].Text; else { foreach (xmldanet.xmlda.ItemValue iv in rslt.Items) { txt += iv.ItemName; if (iv.ResultID == null) // success { txt += " = " + iv.Value.ToString() + "\r\n"; obj.Add(txt); } else txt += " : Error: " + iv.ResultID.Name + "\r\n"; } } return txt; } I am using the namespaces as follows using xmldanet; using xmldanet.xmlda; I have installed XMLDA.NET client component evaluation. In this there is an in built Test client which successfully reads the values of these data items from the remote OPC server. I also provides the template through which we can build the OPC based applications. In the above code I am trying to read the values of the data items but i am not able to read the values. I have applied the breakpoint. In that I can see that the condition if (iv.ResultID == null) becomes false & also there is null values in the variable rslt. Please tell me where I am doing mistake ? how should I correct my mistake ? can provide me the correct code ?

  • No norwegian characters in LaTeX

    - by DreamCodeR
    Hi, I have translated a document from English to Norwegian in the LaTeX format, and while using norwegian special characters, I get an error using \usepackage[utf8x]{inputenc} to try and display the norwegian (scandinavian) special characters in PostScript/PDF/DVI format, saying Package utf8x Error: MalformedUTF-8sequence. So while that didn't work, I tried out another possible solution: \usepackage{ucs} \usepackage[norsk]babel And when I tried to save that in Emacs I get this message: These default coding systems were tried to encode text in the buffer `lol.tex': (utf-8-unix (905 . 4194277) (916 . 4194245) (945 . 4194278) (950 . 4194277) (954 . 4194296) (990 . 4194277) (1010 . 4194277) (1013 . 4194278) (1051 . 4194277) (1078 . 4194296) (1105 . 4194296)) However, each of them encountered characters it couldn't encode: utf-8-unix cannot encode these: \345 \305 \346 \345 \370 \345 \345 \346 \345 \370 ... Thanks to Emacs I have the possibility to check out the properties of those characters and the first one tells me: character: \345 (4194277, #o17777745, #x3fffe5) preferred charset: eight-bit (Raw bytes 128-255) code point: 0xE5 syntax: w which means: word buffer code: #xE5 file code: not encodable by coding system utf-8-unix display: not encodable for terminal Which doesn't tell me much. When I try to build this with texi2dvi --dvipdf filename.text I get a perfectly fine PDF, all without the special norwegian characters. When I am about to save Emacs also ask me: "Select coding system (default raw-text):" And I type in utf-8 to choose its coding system. I have also tried to choose default raw-text to see if I get some different result. But nothing. At last I tried \lstset{inputencoding=utf8x, extendedchars=\true} ... a code I came over while trying to google the solution to this problem. Which gives me this error: Undefined control sequence. So basically, I have tried every encoding option I have been able to find and nothing works. I am desperately trying to make this work since the norwegian translation must be published before the deadline. As an additional information I may add that I found out later on that I only had the en_US.UTF-8 in my locale, so I added nb_NO.UTF-8 and nb_NO.ISO-8859-15 and ran locale-gen + reboot without any changes. I hope I provided enough information to get some assistance, the characters in question is æ ø å.

The simple intent here is to make a list of station, then make a list of detectors at a station. This is a small piece of the XML. It would have multiple StationInventory elements. I'm using the data as the source for an asp:xml control and the xslt file as the transformsource. var service = new InternalService(); var result = service.StationInventory(); invXml.DocumentContent = result; invXml.TransformSource = "StationInventory.xslt"; invXml.DataBind(); Any tips are of course appreciated. Have a terrific weekend. Cheers, ~ck

  • WPF Linear Fill

    Hi, I have found some example code that creates a gradient fill in a WPF rectangle control: <Rectangle Height="{Binding ElementName=txtName}" Width="{Binding ElementName=txtName}"> <Rectangle.Fill> <LinearGradientBrush> <GradientStop Color="Silver" Offset="0.0" /> <GradientStop Color="Black" Offset="0.5" /> <GradientStop Color="white" Offset="1.0" /> </LinearGradientBrush> </Rectangle.Fill> </Rectangle> I have some written some code that displays a collection of ListBox's that contain details from MyObject: <UserControl.Resources> <DataTemplate x:Key="CustomerTemplate"> <Border BorderThickness="2" BorderBrush="Silver" CornerRadius="5" Padding="1" Height="50"> <Grid x:Name="thisGrid"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <StackPanel Orientation="Horizontal" > <Image Source="C:\MyImage.jpg" Height="50" Width="100" ></Image> </StackPanel> <Border Grid.Column="1" Margin="0" Padding="0"> <StackPanel Orientation="Vertical"> <TextBlock Name="txtName" Text="{Binding Name}" Background="Silver" Foreground="Black" FontSize="16" FontWeight="Bold" Height="25"/> </StackPanel> </Border> </Grid> </Border> </DataTemplate> </UserControl.Resources> <ListBox ItemsSource="{Binding}" ItemTemplate="{StaticResource CustomerTemplate}" Name="grdList" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" > </ListBox> I would like to apply the same stlye of fill that i get with the first example, in each of my ListBox's. I can't quite figure out how to do this. Can anyone help? Thanks

  • DependencyProperty binding not happening on initial load

    - by Ari Roth
    I'm trying to do something simple -- make a DependencyProperty and then bind to it. However, the getter doesn't appear to fire when I start up the app. (I'm guessing the solution will make me smack my head and go "Doh!", but still. :) ) Any ideas? Code-behind code: public static readonly DependencyProperty PriorityProperty = DependencyProperty.Register("Priority", typeof (Priority), typeof (PriorityControl), null); public Priority Priority { get { return (Priority)GetValue(PriorityProperty); } set { SetValue(PriorityProperty, value); } } Control XAML: <ListBox Background="Transparent" BorderThickness="0" ItemsSource="{Binding Path=Priorities}" Name="PriorityList" SelectedItem="{Binding Path=Priority, Mode=TwoWay}"> <ListBox.ItemTemplate> <DataTemplate> <Grid Height="16" Width="16"> <Border BorderBrush="Black" BorderThickness="2" CornerRadius="3" Visibility="{Binding RelativeSource= {RelativeSource Mode=FindAncestor, AncestorType=ListBoxItem}, Path=IsSelected, Converter={StaticResource boolToVisibilityConverter}}" /> <Border CornerRadius="3" Height="12" Width="12"> <Border.Background> <SolidColorBrush Color="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListBoxItem}, Path=Content, Converter={StaticResource priorityToColorConverter}}" /> </Border.Background> </Border> </Grid> </DataTemplate> </ListBox.ItemTemplate> <ListBox.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal"/> </ItemsPanelTemplate> </ListBox.ItemsPanel> </ListBox> Binding statement: <UI:PriorityControl Grid.Column="8" Priority="{Binding Path=Priority}" VerticalAlignment="Center"/> Some other notes: Binding is in a UserControl UserControl contains the PriorityControl PriorityControl contains the DependencyProperty I've checked that the data the UserControl is getting the appropriate data -- every other binding works. If I change the selection on the PriorityControl via the mouse, everything fires as appropriate. It's just that initial setting of the value that isn't working. Priority is an enum.

  • Stack Overflow Exploit in C

    - by Fernando Gonzalez
    Hey there guys, the question is actually about stack overflows in C. I have an assigment that I can not get done for the life of me, i've looked at everything in the gdb and I just cant figure it. The question is the following: int i,n; void confused() { printf("who called me"); exit(0); } void shell_call(char *c) { printf(" ***Now calling \"%s\" shell command *** \n",c); system(c); exit(0); } void victim_func() { int a[4]; printf("[8]:%x\n", &a[8]); printf("Enter n: "); scanf("%d",&n); printf("Enter %d HEX Values \n",n); for(i=0;i<n;i++) scanf("%x",&a[i]); printf("Done reading junk numbers\n"); } int main() { printf("ls=736c --- ps = 7370 --- cal = 6c6163\n"); printf("location of confused %x \n", confused); printf("location of shell_call %x \n", shell_call); victim_func(); printf("Done, thank you\n"); } Ok, so I managed to get the first question correctly, which is to arbitrarily call one of the two functions not explicitly called in the main path. By the way, this has to be done while running the program without any modifications. I did this by running the program, setting N to 7, which gets me to the Function Pointer of the victim_func frame, I write a[7] with the memory address of confused or shell_call, and it works. (I have a 64 bit machine, thats why I have to get it to 7, since the EBI pointer is 2 ints wide, instead of 1) My question is the following, how could I control which argument gets passed to the shell_code funcion? ie. how do i write a string to char* c. The whole point is executing unix commands like "ps" etc, by running only the program. I figured writing the EBI pointer with the hex representation of "ps" and setting the arg list of shell_call to that, but that didn't work. I also tried inputing argsv arguments and setting the arg list of shell_call to the arg_list of main, but didnt work either. I think the second version should work, but i believe im not setting the arg list of the new stack frame correctly ( I did it by writing a[8] to 0, since its the first part of the functin pointer, and writing a[9]=736c and a[10]=0000, but its probably not right since those are the parameters of victim_func. So how do i access the parameters of shell_call?

  • Vbscript - Creating a script that mirrors several sets of folders

    - by Kenny Bones
    Ok, this is my problem. I'm doing a logonscript that basically copies Microsoft Word templates from a serverpath on to a local path of each computer. This is done using a check for group membership. If MemberOf(ObjGroupDict, "g_group1") Then oShell.Run "%comspec% /c %LOGONSERVER%\SYSVOL\mydomain.com\scripts\ROBOCOPY \\server\Templates\Group1\OFFICE2003\ " & TemplateFolder & "\" & " * /E /XO", 0, True End If Previously I used the /MIR switch of robocopy, which is exellent. But, if a user is member of more than one group, the /MIR switch removes the content from the first group, since it's mirroring the content from the second group. Meaning, I can't have both contents. This is "solved" by not using the /MIR switch and just let the content get copied anyway. BUT the whole idea of having the templates on a server is so that I can control the content the users receive through the script. So if I delete a file or folder from the server path, this doesn't replicate on the local computer. Since I don't use the /MIR switch anymore. Comprende? So, what do I do? I did a small script that basically checks the folders and files and then removes them accordingly, but this actually ended up being the same functionality as the /MIR switch anyway. How do I solve this problem? Edit: I've found that what I actually need is a routine that scans my local template folder for files and folders and checks if the same structure exists in any of the source template folders. The server template folders are set up like this: \\fileserver\templates\group1\ \\fileserver\templates\group2\ \\fileserver\templates\group3\ \\fileserver\templates\group4\ \\fileserver\templates\group5\ \\fileserver\templates\group6\ And the script that does the copying is structures like this (pseudo): If User is MemberOf (group1) Then RoboCopy.exe \\fileserver\templates\group1\ c:\templates\workgroup *.* /E /XO End if If User is MemberOf (group2) Then RoboCopy.exe \\fileserver\templates\group2\ c:\templates\workgroup *.* /E /XO End if If User is MemberOf (group3) Then RoboCopy.exe \\fileserver\templates\group3\ c:\templates\workgroup *.* /E /XO End if Etc etc With the /E switch, I make sure it copies subfolders as well. And the /XO switch only copies files and folders that are newer than those in my local path. But it doesn't consider if the local path contains files or folders that doesn't exist on the server template path. So after the copying is done, I would like to check if any of the files or folders on my c:\templates\workgroup actually exists in either of the sources. And if they don't, delete them from my local path. Something that could be combined in these memberchecks perhaps?

  • Lifetime issue of IDisposable unmanaged resources in a complex object graph?

    - by stakx
    This question is about dealing with unmanaged resources (COM interop) and making sure there won't be any resource leaks. I'd appreciate feedback on whether I seem to do things the right way. Background: Let's say I've got two classes: A class LimitedComResource which is a wrapper around a COM object (received via some API). There can only be a limited number of those COM objects, therefore my class implements the IDisposable interface which will be responsible for releasing a COM object when it's no longer needed. Objects of another type ManagedObject are temporarily created to perform some work on a LimitedComResource. They are not IDisposable. To summarize the above in a diagram, my classes might look like this: +---------------+ +--------------------+ | ManagedObject | <>------> | LimitedComResource | +---------------+ +--------------------+ | o IDisposable (I'll provide example code for these two classes in just a moment.) Question: Since my temporary ManagedObject objects are not disposable, I obviously have no control over how long they'll be around. However, in the meantime I might have Disposed the LimitedComObject that a ManagedObject is referring to. How can I make sure that a ManagedObject won't access a LimitedComResource that's no longer there? +---------------+ +--------------------+ | managedObject | <>------> | (dead object) | +---------------+ +--------------------+ I've currently implemented this with a mix of weak references and a flag in LimitedResource which signals whether an object has already been disposed. Is there any better way? Example code (what I've currently got): LimitedComResource: class LimitedComResource : IDisposable { private readonly IUnknown comObject; // <-- set in constructor ... void Dispose(bool notFromFinalizer) { if (!this.isDisposed) { Marshal.FinalReleaseComObject(comObject); } this.isDisposed = true; } internal bool isDisposed = false; } ManagedObject: class ManagedObject { private readonly WeakReference limitedComResource; // <-- set in constructor ... public void DoSomeWork() { if (!limitedComResource.IsAlive()) { throw new ObjectDisposedException(); // ^^^^^^^^^^^^^^^^^^^^^^^ // is there a more suitable exception class? } var ur = (LimitedComResource)limitedComResource.Target; if (ur.isDisposed) { throw new ObjectDisposedException(); } ... // <-- do something sensible here! } }

  • Problem with memory leaks

    - by user191723
    Sorry, having difficulty formattin code to appear correct here??? I am trying to understand the readings I get from running instruments on my app which are telling me I am leaking memory. There are a number, quite a few in fact, that get reported from inside the Foundation, AVFoundation CoreGraphics etc that I assume I have no control over and so should ignore such as: Malloc 32 bytes: 96 bytes, AVFoundation, prepareToRecordQueue or Malloc 128 bytes: 128 bytes, CoreGraphics, open_handle_to_dylib_path Am I correct in assuming these are something the system will resolve? But then there are leaks that are reported that I believe I am responsible for, such as: This call reports against this line leaks 2.31KB [self createAVAudioRecorder:frameAudioFile]; Immediately followed by this: -(NSError*) createAVAudioRecorder: (NSString *)fileName { // flush recorder to start afresh [audioRecorder release]; audioRecorder = nil; // delete existing file to ensure we have clean start [self deleteFile: fileName]; VariableStore *singleton = [VariableStore sharedInstance]; // get full path to target file to create NSString *destinationString = [singleton.docsPath stringByAppendingPathComponent: fileName]; NSURL *destinationURL = [NSURL fileURLWithPath: destinationString]; // configure the recording settings NSMutableDictionary *recordSettings = [[NSMutableDictionary alloc] initWithCapacity:6]; //****** LEAKING 384 BYTES [recordSettings setObject:[NSNumber numberWithInt:kAudioFormatLinearPCM] forKey: AVFormatIDKey]; //***** LEAKING 32 BYTES float sampleRate = 44100.0; [recordSettings setObject:[NSNumber numberWithFloat: sampleRate] forKey: AVSampleRateKey]; //***** LEAKING 48 BYTES [recordSettings setObject:[NSNumber numberWithInt:2] forKey:AVNumberOfChannelsKey]; int bitDepth = 16; [recordSettings setObject: [NSNumber numberWithInt:bitDepth] forKey:AVLinearPCMBitDepthKey]; //***** LEAKING 48 BYTES [recordSettings setObject:[NSNumber numberWithBool:YES] forKey:AVLinearPCMIsBigEndianKey]; [recordSettings setObject:[NSNumber numberWithBool: NO]forKey:AVLinearPCMIsFloatKey]; NSError *recorderSetupError = nil; // create the new recorder with target file audioRecorder = [[AVAudioRecorder alloc] initWithURL: destinationURL settings: recordSettings error: &recorderSetupError]; //***** LEAKING 1.31KB [recordSettings release]; recordSettings = nil; // check for erros if (recorderSetupError) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"Can't record" message: [recorderSetupError localizedDescription] delegate: nil cancelButtonTitle: @"OK" otherButtonTitles: nil]; [alert show]; [alert release]; alert = nil; return recorderSetupError; } [audioRecorder prepareToRecord]; //***** LEAKING 512 BYTES audioRecorder.delegate = self; return recorderSetupError; } I do not understand why there is a leak as I release audioRecorder at the start and set to nil and I release recordSettings and set to nil?

  • C#: Windows Forms: What could cause Invalidate() to not redraw?

    - by Rosarch
    I'm using Windows Forms. For a long time, pictureBox.Invalidate(); worked to make the screen be redrawn. However, it now doesn't work and I'm not sure why. this.worldBox = new System.Windows.Forms.PictureBox(); this.worldBox.BackColor = System.Drawing.SystemColors.Control; this.worldBox.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle; this.worldBox.Location = new System.Drawing.Point(170, 82); this.worldBox.Name = "worldBox"; this.worldBox.Size = new System.Drawing.Size(261, 250); this.worldBox.TabIndex = 0; this.worldBox.TabStop = false; this.worldBox.MouseMove += new System.Windows.Forms.MouseEventHandler(this.worldBox_MouseMove); this.worldBox.MouseDown += new System.Windows.Forms.MouseEventHandler(this.worldBox_MouseDown); this.worldBox.MouseUp += new System.Windows.Forms.MouseEventHandler(this.worldBox_MouseUp); Called in my code to draw the world appropriately: view.DrawWorldBox(worldBox, canvas, gameEngine.GameObjectManager.Controllers, selectedGameObjects, LevelEditorUtils.PREVIEWS); View.DrawWorldBox: public void DrawWorldBox(PictureBox worldBox, Panel canvas, ICollection<IGameObjectController> controllers, ICollection<IGameObjectController> selectedGameObjects, IDictionary<string, Image> previews) { int left = Math.Abs(worldBox.Location.X); int top = Math.Abs(worldBox.Location.Y); Rectangle screenRect = new Rectangle(left, top, canvas.Width, canvas.Height); IDictionary<float, ICollection<IGameObjectController>> layers = LevelEditorUtils.LayersOfControllers(controllers); IOrderedEnumerable<KeyValuePair<float, ICollection<IGameObjectController>>> sortedLayers = from item in layers orderby item.Key descending select item; using (Graphics g = Graphics.FromImage(worldBox.Image)) { foreach (KeyValuePair<float, ICollection<IGameObjectController>> kv in sortedLayers) { foreach (IGameObjectController controller in kv.Value) { // ... float scale = controller.View.Scale; float width = controller.View.Width; float height = controller.View.Height; Rectangle controllerRect = new Rectangle((int)controller.Model.Position.X, (int)controller.Model.Position.Y, (int)(width * scale), (int)(height * scale)); // cull objects that aren't intersecting with the canvas if (controllerRect.IntersectsWith(screenRect)) { Image img = previews[controller.Model.HumanReadableName]; g.DrawImage(img, controllerRect); } if (selectedGameObjects.Contains(controller)) { selectionRectangles.Add(controllerRect); } } } foreach (Rectangle rect in selectionRectangles) { g.DrawRectangle(drawingPen, rect); } selectionRectangles.Clear(); } worldBox.Invalidate(); } What could I be doing wrong here?

  • Auto-scaffolding Index views in ASP.NET MVC

    - by DanM
    I'm trying to write an auto-scaffolder for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IQueryable<MyViewModel>) and get back an HTML table that uses the DisplayName attribute for the headings (th elements) and Html.Display(propertyName) for the cells (td elements). Each row should correspond to one item in the collection. Here's what I have so far: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <% var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; // Should be generic! var properties = items.First().GetMetadata().Properties .Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm)); %> <table> <tr> <% foreach(var property in properties) { %> <th> <%= property.DisplayName %> </th> <% } %> </tr> <% foreach(var item in items) { %> <tr> <% foreach(var property in properties) { %> <td> <%= Html.Display(property.DisplayName) %> // This doesn't work! </td> <% } %> </tr> <% } %> </table> Two problems with this: I'd like it to be generic. So, I'd like to replace var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; with var items = (IQueryable<T>)Model; or something to that effect. The <td> elements are not working because the Html in <%= Html.Display(property.DisplayName) %> contains the model for the view, which is a collection of items, not the item itself. Somehow, I need to obtain an HtmlHelper object whose Model property is the current item, but I'm not sure how to do that. How do I solve these two problems?

  • Rails 3.1 text_field form helper and jQuery datepicker date format

    - by DanyW
    I have a form field in my Rails view like this: <%= f.text_field :date, :class => "datepicker" %> A javascript function converts all input fields of that class to a jQueryUI datepicker. $(".datepicker").datepicker({ dateFormat : "dd MM yy", buttonImageOnly : true, buttonImage : "<%= asset_path('iconDatePicker.gif') %>", showOn : "both", changeMonth : true, changeYear : true, yearRange : "c-20:c+5" }) So far so good. I can edit the record and it persists the date correctly all the way to the DB. My problem is when I want to edit the record again. When the form is pre-populated from the record it displays in 'yyyy-mm-dd' format. The javascript only formats dates which are selected in the datepicker control. Is there any way I can format the date retrieved from the database? At which stage can I do this? Thanks, Dany. Some more details following the discussion below, my form is spread across two files, a view and a partial. Here's the view: <%= form_tag("/shows/update_individual", :method => "put") do %> <% for show in @shows %> <%= fields_for "shows[]", show do |f| %> <%= render "fields", :f => f %> <% end %> <% end %> <%= submit_tag "Submit"%> <% end %> And here's the _fields partial view: <p> <%= f.label :name %> <%= f.text_field :name %> </p> <p> <%= f.date %> <%= f.label :date %> <%= f.text_field :date, :class => "datepicker" %> </p> Controller code: def edit_individual @shows = Show.find(params[:show_ids]) end

  • How do I add a custom view to iPhone app's UI?

    - by Dr Dork
    I'm diving into iPad development and I'm still learning how everything works together. I understand how to add standard view (i.e. buttons, tableviews, datepicker, etc.) to my UI using both Xcode and Interface Builder, but now I'm trying to add a custom calendar control (TapkuLibrary) to the left window in my UISplitView application. My question is, if I have a custom view (in this case, the TKCalendarMonthView), how do I programmatically add it to one of the views in my UI (in this case, the RootViewController)? Below are some relevant code snippets from my project... RootViewController interface @interface RootViewController : UITableViewController <NSFetchedResultsControllerDelegate> { DetailViewController *detailViewController; NSFetchedResultsController *fetchedResultsController; NSManagedObjectContext *managedObjectContext; } @property (nonatomic, retain) IBOutlet DetailViewController *detailViewController; @property (nonatomic, retain) NSFetchedResultsController *fetchedResultsController; @property (nonatomic, retain) NSManagedObjectContext *managedObjectContext; - (void)insertNewObject:(id)sender; TKCalendarMonthView interface @class TKMonthGridView,TKCalendarDayView; @protocol TKCalendarMonthViewDelegate, TKCalendarMonthViewDataSource; @interface TKCalendarMonthView : UIView { id <TKCalendarMonthViewDelegate> delegate; id <TKCalendarMonthViewDataSource> dataSource; NSDate *currentMonth; NSDate *selectedMonth; NSMutableArray *deck; UIButton *left; NSString *monthYear; UIButton *right; UIImageView *shadow; UIScrollView *scrollView; } @property (readonly,nonatomic) NSString *monthYear; @property (readonly,nonatomic) NSDate *monthDate; @property (assign,nonatomic) id <TKCalendarMonthViewDataSource> dataSource; @property (assign,nonatomic) id <TKCalendarMonthViewDelegate> delegate; - (id) init; - (void) reload; - (void) selectDate:(NSDate *)date; Thanks in advance for all your help! I still have a ton to learn, so I apologize if the question is absurd in any way. I'm going to continue researching this question right now!

  • When using delegates, need better way to do sequential processing

    - by Padawan
    I have a class WebServiceCaller that uses NSURLConnection to make asynchronous calls to a web service. The class provides a delegate property and when the web service call is done, it calls a method webServiceDoneWithXXX on the delegate. There are several web service methods that can be called, two of which are say GetSummary and GetList. The classes that use WebServiceCaller initially need both the summary and list so they are written like this: -(void)getAllData { [webServiceCaller getSummary]; } -(void)webServiceDoneWithGetSummary { [webServiceCaller getList]; } -(void)webServiceDoneWithGetList { ... } This works but there are at least two problems: The calls are split across delegate methods so it's hard to see the sequence at a glance but more important it's hard to control or modify the sequence. Sometimes I want to call just GetSummary and not also GetList so I would then have to use an ugly class-level state variable that tells webServiceDoneWithGetSummary whether to call GetList or not. Assume that GetList cannot be done until GetSummary completes and returns some data which is used as input to GetList. Is there a better way to handle this and still get asynchronous calls? Update based on Matt Long's answer: Using notifications instead of a delegate, it looks like I can solve problem #2 by setting a different selector depending on whether I want the full sequence (GetSummary+GetList) or just GetSummary. Both observers would still use the same notification name when calling GetSummary. I would have to write two separate methods to handle GetSummaryDone instead of using a single delegate method (where I would have needed some class-level variable to tell whether to then call GetList). -(void)getAllData { [[NSNotificationCenter defaultCenter] addObserver:self              selector:@selector(getSummaryDoneAndCallGetList:)                  name:kGetSummaryDidFinish object:nil];     [webServiceCaller getSummary]; } -(void)getSummaryDoneAndCallGetList { [NSNotificationCenter removeObserver] //process summary data [[NSNotificationCenter defaultCenter] addObserver:self              selector:@selector(getListDone:)                  name:kGetListDidFinish object:nil];     [webServiceCaller getList]; } -(void)getListDone { [NSNotificationCenter removeObserver] //process list data } -(void)getJustSummaryData { [[NSNotificationCenter defaultCenter] addObserver:self              selector:@selector(getJustSummaryDone:) //different selector but                  name:kGetSummaryDidFinish object:nil]; //same notification name     [webServiceCaller getSummary]; } -(void)getJustSummaryDone { [NSNotificationCenter removeObserver] //process summary data } I haven't actually tried this yet. It seems better than having state variables and if-then statements but you have to write more methods. I still don't see a solution for problem 1.

  • Would someone mind giving suggestions for this new assembly language?

    - by Noctis Skytower
    Greetings! Last semester in college, my teacher in the Computer Languages class taught us the esoteric language named Whitespace. In the interest of learning the language better with a very busy schedule (midterms), I wrote an interpreter and assembler in Python. An assembly language was designed to facilitate writing programs easily, and a sample program was written with the given assembly mnemonics. Now that it is summer, a new project has begun with the objective being to rewrite the interpreter and assembler for Whitespace 0.3, with further developments coming afterwards. Since there is so much extra time than before to work on its design, you are presented here with an outline that provides a revised set of mnemonics for the assembly language. This post is marked as a wiki for their discussion. Have you ever had any experience with assembly languages in the past? Were there some instructions that you thought should have been renamed to something different? Did you find yourself thinking outside the box and with a different paradigm than in which the mnemonics were named? If you can answer yes to any of those questions, you are most welcome here.
