  • UISegmentedControl Best Practice

    - by Neal L
    Hi all, I'm trying to work out the "best" way to use a UISegmentedControl for an iPhone application. I've read a few posts here on stackoverflow and seen a few people's ideas, but I can't quite sort out the best way to do this. The posts I'm referring to are: http://stackoverflow.com/questions/1559794/changing-views-from-uisegmentedcontrol and http://stackoverflow.com/questions/1047114/how-do-i-use-a-uisegmentedcontrol-to-switch-views It would seem that the options are: Add each of the views in IB and lay them out on top of each other then show/hide them Create each of the subviews separately in IB, then create a container in the main view to populate with the subview that you need Set up one really tall or really wide UIView and animate it left/right or up/down depending on the selected segment Use a UITabBarController to swap out the subviews - seems silly For tables, reload the table and in cellForRowAtIndex and populate the table from different data sources or sections based on the segment option selected (not the case for my app) So which approach is best for subview/non-table approaches? Which is the easiest to implement? Could you share some sample code to the approach? Thanks!

  • Dynamic controls not creating with RSS reader function

    - by TuxMeister
    Hello, I am working on a test project for an RSS reader. I am using Chilkat's module for .NET 3.5. What I am trying to do is this: For each item in the RSS feed, I want to dynamically create some controls (labels) that contain stuff like the title, the link and the publication date. The problem is that only the first control comes up "rssTitle", but not the rest and it's definitely not creating the rest, nor cycling through the RSS items. Any ideas where I'm wrong in my code? Imports Chilkat Public Class Form1 Dim rss As New Chilkat.Rss Dim success As Boolean Dim rssTitle As New Label Dim rssLink As New Label Dim rssPubDate As New Label Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click success = rss.DownloadRss("http://www.engadget.com/rss.xml") If success <> True Then MessageBox.Show(rss.LastErrorText) Exit Sub End If Dim rssChannel As Chilkat.Rss rssChannel = rss.GetChannel(0) If rssChannel Is Nothing Then MessageBox.Show("No channel found.") Exit Sub End If Dim numItems As Long numItems = rssChannel.NumItems Dim i As Long For i = 0 To numItems - 1 Dim rssItem As Chilkat.Rss rssItem = rssChannel.GetItem(i) Me.Controls.Add(rssTitle) With rssTitle .Name = "rssTitle" & Me.Controls.Count.ToString + 1 .Text = "Title: " & rssItem.GetString("title") .Left = 12 .Top = 12 End With Me.Controls.Add(rssLink) With rssLink .Name = "rssLink" & Me.Controls.Count.ToString + 1 .Text = "Link: " & rssItem.GetString("link") .Left = 12 .Top = 12 End With Me.Controls.Add(rssPubDate) With rssPubDate .Name = "rssPubDate" & Me.Controls.Count.ToString + 1 .Text = "Pub date: " & rssItem.GetString("pubDate") .Left = 12 .Top = 12 End With Next End Sub End Class I'm grateful for any help. Thanks!

  • IdHTTP XML, getting xml, help please

    - by user1748535
    Already some day I can not solve the problem. Help than you can. I'm using Delphi 2010, and I can not get through IdHTTP XML document from the site. I always had the answer 403 / HTTP 1.1 and text/html (need text/xml) When using MSXML all well and getting XML file. But I need a proxy, so need idhtop. When using the synapse does not change. Work with msxml: CoInitialize(nil); GetXML:={$IFDEF VER210}CoXMLHTTP{$ELSE}CoXMLHTTPRequest{$ENDIF}.Create; GetXML.open('POST', '***************', false, EmptyParam, EmptyParam); GetXML.setRequestHeader('Host', '***************'); GetXML.setRequestHeader('User-Agent', 'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13'); GetXML.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); GamesBody:='***************'; GetXML.send(GamesBody); Form1.Memo2.Lines.Text:=GetXML.responseText; ResultPage:=GetXML.responseText; if Pos('error code', ResultPage)=0 then begin CoUninitialize; how to set up IdHTTP? All settings have changed 100 times Or a connection to a proxy MSXML?

  • Poll multiple desktops/servers on a network remotely to determine the IP Type: Static or DHCP

    - by Charles Laird
    Had a gentleman answer 90% of my original question, which is to say I now have the ability to poll a device that I am running the below script on. The end goal is to obtain IP type: Static or DHCP on all desktop/servers on a network I support. I have the list of servers that I will input in a batch file, just looking for the code to actually poll the other devices on the network from one location. Output to be viewed: Device name: IP Address: MAC Address: Type: Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller NULL 00:00:F3:44:C6:00 DHCP Generic Marvell Yukon 88E8056 based Ethernet Controller 192.168.1.102 00:00:F3:44:D0:00 DHCP ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection objMOC = objMC.GetInstances(); txtLaunch.Text = ("Name\tIP Address\tMAC Address\tType" +"\r\n"); foreach (ManagementObject objMO in objMOC) { StringBuilder builder = new StringBuilder(); object o = objMO.GetPropertyValue("IPAddress"); object m = objMO.GetPropertyValue("MACAddress"); if (o != null || m != null) { builder.Append(objMO["Description"].ToString()); builder.Append("\t"); if (o != null) builder.Append(((string[])(objMO["IPAddress"]))[0].ToString()); else builder.Append("NULL"); builder.Append("\t"); builder.Append(m.ToString()); builder.Append("\t"); builder.Append(Convert.ToBoolean(objMO["DHCPEnabled"]) ? "DHCP" : "Static"); builder.Append("\r\n"); } txtLaunch.Text = txtLaunch.Text + (builder.ToString()); I'm open to recommendations here.

    Hi i have a simple question. Ofcourse it has many answers but i cannt choose right keywords to google. How i can bind a subclass to my wpf control? for example: It's my class. public class SiteFieldInfo<T> { public string Name { get; set; } public T Value { get; set; } public List<string> PositiveXPathExpressions { get; set; } public List<string> NegativeXPathExpressions { get; set; } } public class SiteInfo { public SiteFieldInfo<string> Author { get; set; } public SiteFieldInfo<DateTime> Date { get; set; } public SiteFieldInfo<string> Source { get; set; } } And i want to bind property Value from SiteFieldInfo to Text property of TextBox control. c# code: stackPanel1.DataContext = SiteInfoInstance; xaml code: <StackPanel Name="stackPanel1"> <TextBlock Text="Author" Grid.Row="0" Grid.Column="0" /> <TextBox Grid.Row="0" Grid.Column="1" Text="{Binding Path=Author.Value}" /> </StackPanel> It's not working.

  • ACL actions tag cause 'roles resource tree' draw incorrectly in admin/system/permissions/roles

    - by latvian
    Hi, We created new action similar to 'hold', 'ship' and others in the 'sales_order/view' admin section that can be triggered by clicking at the button. Afterward, we added our new action to the ACL with the following code in config.xml: <acl> <resources> <admin> <children> <sales> <children> <order> <children> <actions translate="title"> <title>Actions</title> <children> <shipNew translate="title"><title>Ship Ups</title></shipNew> </children> </actions> </children> <sort_order>10</sort_order> </order> </children> </sales> </children> </admin> </resources> </acl> ACL functionality works, however, in the 'Resources Tree'(System/Permissions/Roles/Role Resources) our new action does never show up as selected(checked) even thou it is allowed for particular Role. I can see that from table 'admin_rule' with resource id for our new action that it is allowed, so it needs to be selected, but it is not. When trying to solve this issue i looked into the template(permissions/rolesedit.phtml) and I found that the 'resource tree' is draw with Javascript...thats where i got stock due to my limited knowledge in Javascript. Why the resource tree does not display our new ACL entry correctly, that is the check box is never checked? Thank You for helping margots

  • GXT Performance Issues

    - by pearl
    Hi All, We are working on a rather complex system using GXT. While everything works great on FF, IE (especially IE6) is a different story (looking at more than 10 seconds until the browser renders the page). I understand that one of the main reasons is DOM manipulation which is a disaster under IE6 (See http://www.quirksmode.org/dom/innerhtml.html). This can be thought to be a generic problem of a front-end Javascript framework (i.e. GWT) but a simple code (see below) that executes the same functionality proofs otherwise. In fact, under IE6 - getSomeGWT() takes 400ms while getSomeGXT() takes 4 seconds. That's a x10 factor which makes a huge different for the user experience !!! private HorizontalPanel getSomeGWT() { HorizontalPanel pointsLogoPanel = new HorizontalPanel(); for (int i=0; i<350; i++) { HorizontalPanel innerContainer = new HorizontalPanel(); innerContainer.add(new Label("some GWT text")); pointsLogoPanel.add(innerContainer); } return pointsLogoPanel; } private LayoutContainer getSomeGXT() { LayoutContainer pointsLogoPanel = new LayoutContainer(); pointsLogoPanel.setLayoutOnChange(true); for (int i=0; i<350; i++) { LayoutContainer innerContainer = new LayoutContainer(); innerContainer.add(new Text("just some text")); pointsLogoPanel.add(innerContainer); } return pointsLogoPanel; } So to solve/mitigate the issue one would need to - a. Reduce the number of DOM manipulations; or b. Replace them with innerHTML. AFAIK, (a) is simply a side effect of using GXT and (b) is only possible with UiBinder which isn't supported yet by GXT. Any ideas? Thanks in advance!

  • HtmlHelper Getting the route name

    - by Simon G
    Hi, I've created a html helper that adds a css class property to a li item if the user is on the current page. The helper looks like this: public static string MenuItem( this HtmlHelper helper, string linkText, string actionName, string controllerName, object routeValues, object htmlAttributes ) { string currentControllerName = ( string )helper.ViewContext.RouteData.Values["controller"]; string currentActionName = ( string )helper.ViewContext.RouteData.Values["action"]; var builder = new TagBuilder( "li" ); // Add selected class if ( currentControllerName.Equals( controllerName, StringComparison.CurrentCultureIgnoreCase ) && currentActionName.Equals( actionName, StringComparison.CurrentCultureIgnoreCase ) ) builder.AddCssClass( "active" ); // Add link builder.InnerHtml = helper.ActionLink( linkText, actionName, controllerName, routeValues, htmlAttributes ); // Render Tag Builder return builder.ToString( TagRenderMode.Normal ); } I want to expand this class so I can pass a route name to the helper and if the user is on that route then it adds the css class to the li item. However I'm having difficulty finding the route the user is on. Is this possible? The code I have so far is: public static string MenuItem( this HtmlHelper helper, string linkText, string routeName, object routeValues, object htmlAttributes ) { string currentControllerName = ( string )helper.ViewContext.RouteData.Values["controller"]; string currentActionName = ( string )helper.ViewContext.RouteData.Values["action"]; var builder = new TagBuilder( "li" ); // Add selected class // Some code for here // if ( routeName == currentRoute ) AddCssClass; // Add link builder.InnerHtml = helper.RouteLink( linkText, routeName, routeValues, htmlAttributes ); // Render Tag Builder return builder.ToString( TagRenderMode.Normal ); } BTW I'm using MVC 1.0. Thanks

  • jQuery fadein fadeout divs over set interval

    - by theDawckta
    I want to fadeOut the first div in a collection and then fadeIn the next div. The fade in out would trigger at a set time. The number of items in the collection is 1 to n. Here is an example of the html; <div class="contentPanel"> <div class="content"> <div style="border: solid 2px black; text-align: center"> This is first content </div> </div> <div class="content"> <div style="border: solid 2px black; text-align: center"> This is second content </div> </div> <div class="content"> <div style="border: solid 2px black; text-align: center"> This is third content </div> </div> </div> So on page load the first "content" class would be visible, after x amount of time, the current "content" would fadeout and the next "content" would fade in. When it got to the nth "content" it would start over, fadeout the nth "content" and fadein the first "content". This behavior would loop continuously.

  • Silverlight performance with a large number of Objects Org Chart.

    - by KC
    Hello, I’m working on a org chart project(SL 3) and I’m seeing the UI thread hang when the chart is building around 2,000 nodes and when it renders it takes about a min and then FPS drop to a crawl. Here is the code flow. Page.xaml.cs calls a wcf service that returns a list of AD users. Then we use Linq to build a collection of nodes to bind to the Orgchart.cs OrgChart.cs is a canvas and displays a collection of nodes and connecting lines. Node.cs is a canvas and has user data can contain children nodes. NodeContent.xaml is a user control that has borders so I can set the background, textblocks to display user's data, Events that handle the selected and expaned nodes, and storyboards that resize the nodes when they are selected or expanded.I noticed during hours of debugging , here in the InitializeComponent(); section where it loads the xaml it seems to be where the preformance hit is happening. System.Windows.Application.LoadComponent(this, new System.Uri("/Silverlight.Custom;component/NodeContent.xaml", System.UriKind.Relative)); So I guess I have two questions. Can threading help in any way with the UI thread hanging while drawing the nodes? How can I avoid the hit when calling this user control? Any advice or direction anyone can lend would be greatly appreciated. Thanks, KC

  • Character Encoding: â??

    - by akaphenom
    I am trying to piece together the mysterious string of characters â?? I am seeing quite a bit of in our database - I am fairly sure this is a result of conversion between character encodings, but I am not completely positive. The users are able to enter text (or cut and paste) into a Ext-Js rich text editor. The data is posted to a severlet which persists it to the database, and when I view it in the database i see those strange characters... is there any way to decode these back to their original meaning, if I was able to discover the correct encoding - or is there a loss of bits or bytes that has occured through the conversion process? Users are cutting and pasting from multiple versions of MS Word and PDF. Does the encoding follow where the user copied from? Thank you website is UTF-8 We are using ms sql server 2005; SELECT serverproperty('Collation') -- Server default collation. Latin1_General_CI_AS SELECT databasepropertyex('xxxx', 'Collation') -- Database default SQL_Latin1_General_CP1_CI_AS and the column: Column_name Type Computed Length Prec Scale Nullable TrimTrailingBlanks FixedLenNullInSource Collation text varchar no -1 yes no yes SQL_Latin1_General_CP1_CI_AS The non-Unicode equivalents of the nchar, nvarchar, and ntext data types in SQL Server 2000 are listed below. When Unicode data is inserted into one of these non-Unicode data type columns through a command string (otherwise known as a "language event"), SQL Server converts the data to the data type using the code page associated with the collation of the column. When a character cannot be represented on a code page, it is replaced by a question mark (?), indicating the data has been lost. Appearance of unexpected characters or question marks in your data indicates your data has been converted from Unicode to non-Unicode at some layer, and this conversion resulted in lost characters. So this may be the root cause of the problem... and not an easy one to solve on our end.

  • Are web-safe colors still relevant?

    - by Gavin Miller
    Since the vast majority of monitors are 16-bit color or more, including mobile devices, does it make sense to even consider web-safe colors when choosing color schemes? Or is it something that ought to be relegated to history as a piece of trivia? For those of you that don't know what web-safe colors are: Another set of 216 color values is commonly considered to be the "web-safe" color palette, developed at a time when many computer displays were only capable of displaying 256 colors. A set of colors was needed that could be shown without dithering on 256-color displays; the number 216 was chosen partly because computer operating systems customarily reserved sixteen to twenty colors for their own use; it was also selected because it allows exactly six shades each of red, green, and blue (6 × 6 × 6 = 216). The list of colors is often presented as if it has special properties that render them immune to dithering. In fact, on 256-color displays applications can set a palette of any selection of colors that they choose, dithering the rest. These colors were chosen specifically because they matched the palettes selected by the then leading browser applications. [Wikipedia]

  • Before data is entered, is there a way to make a grouped table graphic placeholder?

    - by Matt Winters
    I have a grouped table with 3 sections, each section with a title. The 1st and 3rd sections always have only 1 row of information so before any user data is entered, I just put some words like "Enter Data Here..." as placeholder text. This text is edited (replaced) by the user with their own actual data. No problem. The 2nd section however will contain several rows of information entered by user and I'd prefer not to enter placeholder data in row 0, having the user Edit the first row of data then Add subsequent rows. If the numberOfRowsInSection is set to 0, the title for the 3rd section comes close to the title for the 2nd section and it looks ugly. The best that I could come with, and I don't know to do it, is to have a fake graphic placeholder on the striped background (between the 2nd and third titles) that looks like a single row in the 2nd section, put "Enter Data Here..." text in the graphic, and then the first row of actual data entered and all subsequent rows will cover it up. Can anyone tell me how to do this or offer a better suggestion. Thanks.

  • Parameterized Queries /Without/ using queries.

    - by Aren B
    I've got a bit of a poor situation here. I'm stuck working with commerce server, which doesn't do a whole lot of sanitization/parameterization. I'm trying to build up my queries to prevent SQL Injection, however some things like the searches / where clause on the search object need to be built up, and there's no parameterized interface. Basically, I cannot parameterize, however I was hoping to be able to use the same engine to BUILD my query text if possible. Is there a way to do this, aside from writing my own parameterizing engine which will probably still not be as good as parameterized queries? Update: Example The where clause has to be built up as a sql query where clause essentially: CatalogSearch search = /// Create Search object from commerce server search.WhereClause = string.Format("[cy_list_price] > {0} AND [Hide] is not NULL AND [DateOfIntroduction] BETWEEN '{1}' AND '{2}'", 12.99m, DateTime.Now.AddDays(-2), DateTime.Now); *Above Example is how you refine the search, however we've done some testing, this string is NOT SANITIZED. This is where my problem lies, because any of those inputs in the .Format could be user input, and while i can clean up my input from text-boxes easily, I'm going to miss edge cases, it's just the nature of things. I do not have the option here to use a parameterized query because Commerce Server has some insane backwards logic in how it handles the extensible set of fields (schema) & the free-text search words are pre-compiled somewhere. This means I cannot go directly to the sql tables What i'd /love/ to see is something along the lines of: SqlCommand cmd = new SqlCommand("[cy_list_price] > @MinPrice AND [DateOfIntroduction] BETWEEN @StartDate AND @EndDate"); cmd.Parameters.AddWithValue("@MinPrice", 12.99m); cmd.Parameters.AddWithValue("@StartDate", DateTime.Now.AddDays(-2)); cmd.Parameters.AddWithValue("@EndDate", DateTime.Now); CatalogSearch search = /// constructor search.WhereClause = cmd.ToSqlString();

  • template engine implementation

    - by qwerty
    I am currently building this small template engine. It takes a string containing the template in parameter, and a dictionary of "tags,values" to fill in the template. In the engine, I have no idea of the tags that will be in the template and the ones that won't. I am currently iterating (foreach) on the dictionnary, parsing my string that I have put in a string builder, and replacing the tags in the template by their corresponding value. Is there a more efficient/convenient way of doing this? I know the main drawback here is that the stringbuilder is parsed everytime entirely for each tag, which is quite bad... (I am also checking, though not included in the sample, after the process that my template does not contain any tag anymore. They are all formated in the same way: @@tag@@) //Dictionary<string, string> tagsValueCorrespondence; //string template; StringBuilder outputBuilder = new StringBuilder(template); foreach (string tag in tagsValueCorrespondence.Keys) { outputBuilder.Replace(tag, tagsValueCorrespondence[tag]); } template = outputBuilder.ToString(); Responses: @Marc: string template = "Some @@foobar@@ text in a @@bar@@ template"; StringDictionary data = new StringDictionary(); data.Add("foo", "value1"); data.Add("bar", "value2"); data.Add("foo2bar", "value3"); Output: "Some text in a value2 template" instead of: "Some @@foobar@@ text in a value2 template"

  • VB.NET invalid cast exception

    - by user127147
    Hi there, I have a simple application to store address details and edit them. I have been away from VB for a few years now and need to refreash my knowledge while working to a tight deadline. I have a general Sub responsible for displaying a form where user can add contact details (by pressing button add) and edit them (by pressing button edit). This sub is stored in a class Contact. The way it is supposed to work is that there is a list with all the contacts and when new contact is added a new entry is displayed. If user wants to edit given entry he or she selects it and presses edit button Public Sub Display() Dim C As New Contact C.Cont = InputBox("Enter a title for this contact.") C.Fname = frmAddCont.txtFName.Text C.Surname = frmAddCont.txtSName.Text C.Address = frmAddCont.txtAddress.Text frmStart.lstContact.Items.Add(C.Cont.ToString) End Sub I call it from the form responsible for adding new contacts by Dim C As New Contact C.Display() and it works just fine. However when I try to do something similar using the edit button I get errors - "Unable to cast object of type 'System.String' to type 'AddressBook.Contact'." Dim C As Contact If lstContact.SelectedItem IsNot Nothing Then C = lstContact.SelectedItem() C.Display() End If I think it may be something simple however I wasn't able to fix it and given short time I have I decided to ask for help here. Thank you

  • ComboBox exception caused in winforms FormClosing event

    - by Spooky2010
    Using c# vs2008 winforms I have an application with a bunch of child winforms. Each time a form is closed I need to store the current selected value of a combobox that is on each form to a Global application variable so that I can track it and use it in new forms. The combobox is populated on form start via a method to set its datasource to an ArrayList of items What I have found is if the combobox is populated with items in the designer, and you try to get the combobox value in the form closing event, I always get a NullReferenceException. However if the comboBox has an datasource like I DO have in my application and I try to get the combobox value in the form closing event then I would say 95% of the time I DO NOT get the NullReferenceException, but I do get it 5% of the time. That ratio can even vary depending on what computer I run the application on. for example I have 1 computer where the exception always occurs. My question is therefore what is (the best) way to get the value of the combobox, last thing before the form closes without causing the exception. I would def prefer to do it last thing before the form closes rather than track it with every selected index change event. Any advice appreciated.

  • Set predefine form value (webbrowser control)

    - by Khou
    Hi I want to load my windows form: web browser thats using the webbrowser control, It would load a web page, and load my defination and search for elements that has been define, it will then assign the default values and these values can not be changed by the end user. Example If my application finds "FirstName" it would always assign the value "John" If my application finds "LastName" it would always assign the value "Smith" (these values should not be changed by the end user). Here's how to do it in HTML/JAVASCRIPT, but how do i do this in a windows form? HTML <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title>page title</title> <script script type="text/javascript" src="demo1.js"></script> </head> <body onload="def(document.someform, 'name', 'my default name value');"> <h2 style="color: #8e9182">test form title</h2> <form name="someform" id="someform_frm" action="#"> <table cellspacing="1"> <tr><td><label for="name">NameX: </label></td><td><input type="text" size="30" maxlength="155" name="name" onchange="def(document.someform, 'name', 'my default name value');"></td></tr> <tr><td><label for="name2">NameY: </label></td><td><input type="text" size="30" maxlength="155" name="name2"></td></tr> <tr><td colspan="2"><input type="button" name="submit" value="Submit" onclick="showFormData(this.form);" ></td></table> </form> </body> </html> JAVASCRIPT function def(oForm, element_name, def_txt) { oForm.elements[element_name].value = def_txt; }

  • Binding Data to a TextBlock using Domain Data Source

    - by TFisher
    I have a map with hotspots for each state (done in Expression Blend). I capture each MouseEnter of the state (1 thru 50). I pass that into my Domain Data Source: Dim activebox As Path = TryCast(sender, Path) activebox.Fill = mouseOverColor Dim StateID As Integer = CInt(Right(activebox.Name, 2)) Dim _StateContext As New StateContext myDataGrid.ItemsSource = _StateContext.States _StateContext.Load(_StateContext.GetStateByStateIDQuery(StateID.Text)) The above works fine for a datagrid, listbox and even a dataform. But I created a popup with a stackpanel that has textblocks. popupStatesBox.DataContext = ?????????????? popupStatesBox.IsOpen = True 'popup does open but has no data -- popupStatesBox.xaml <Popup x:Name="popupStatsBox" Margin="8,35,0,8" DataContext="{Binding}" IsOpen="false" Width="268" HorizontalAlignment="Left"> <StackPanel x:Name="Layout" Background="Black"> <TextBlock x:Name="tbState" Text="{Binding StateName /> <TextBlock x:Name="tbAbbrev" Text="{Binding Abbreviation}" /> </StackPanel> </Popup> How do I get the textblocks to display the values from the _StateContext. StackPanel has DataContext but no ItemsSource. What am I missing?
