  • Launching and Intent from file and mime type

    - by stonedonkey
    I've reviewed all the similar questions here, but I can't for the life of me figure out what I'm doing wrong. I've written an application that tries to launch various files, sort of a file browser, when a file is clicked it tries to launch the program based on it's associated MIME type or I want it to present the "Choose Application to Launch" dialog. Here's the code I'm using to launch: File file = new File(app.mediaPath() + "/" +_mediaFiles.get(position)); Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW); String extension = android.webkit.MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(file).toString()); String mimetype = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension); myIntent.setDataAndType(Uri.fromFile(file),mimetype); startActivity(myIntent); This fails and generates a: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=file:///file:/mnt/sdcard/roms/nes/Baseball_simulator.nes } Now if I install OI File Manager for instance, it opens instead of this error being thrown, and then if I click the same file from within in it, it launches the approriate dialogs. I have noticed that the MIME type for that particular file fails, but other mime types like .zip do return values. Am I missing something that when the MIME type is null to call a dialog that lets the user select? I've tried other variations of launching the app, including not setting the mime type and only using .setData with no success. The action I want to happen is, a user clicks a file, if it's associated with an application that app launches, if not, the user gets the "Complete action using" dialog with a list of apps. Thanks for any advice.

  • Making IE "forget" information entered in form when using back button.

    - by typoknig
    I have a page with a form where many of the fields are populated from variables passed in the URL. Those fields are disabled (NON-EDITABLE) and are only there for the user to view. The remaining fields require user input and are NOT disabled (EDITABLE). When the form is submitted a confirmation page comes up. It may be the case that the user needs to submit several of these forms where the NON-EDITABLE information is identical from form to form, so being able to go back to the form page from the confirmation page would save a lot of time. The way I want this to work is when a user presses the back button all the NON-EDITABLE fields are populated, but the EDITABLE fields are blank. This is what Firefox is doing, but IE8 is does not "forget" what has been entered in the EDITABLE fields. To disable the cache the following appears at the beginning of my page AND at the end of my page. <head> <meta http-equiv="Pragma" content="no-cache"/> <meta http-equiv="Cache-Control" content="no-store"/> <head/> What more must I do to make IE forget what was entered in the EDITABLE fields when the back button is pressed? All of my pages are generated with PHP if that matters. EDIT: It appears to me that this is a problem of IE caching my page even though I have told it not to. Are my meta tags correct? Do I need to do something else to prevent IE from caching my page?

  • progressbar not updating binding

    - by BoteRock
    I am trying to make a progress bar that updates when a property value changes I have followed other questions but i don't know what is wrong with it. This is XAML code: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" x:Class="WpfApplication1.MainWindow" Title="MainWindow"> <Grid Margin="0,0,-8,1"> <ProgressBar Value="{Binding Progreso, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:MainWindow}}}" Margin="105,95,207,350"/> <Button Content="Button" Click="Button_Click" Margin="218,232,333,217"/> </Grid> </Window> it is basically a progress bar with the binding and a button with a listener that increases Progreso by 10 this is the C# code: public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } public event PropertyChangedEventHandler PropertyChanged; protected void NotifyPropertyChanged(string sProp) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(sProp)); } } float progreso = 10; public float Progreso { get { return progreso; } set { progreso = value; NotifyPropertyChanged("Progreso"); } } private void Button_Click(object sender, RoutedEventArgs e) { this.Progreso = this.Progreso + 10; } } I tried to keep it simple but I couldn't get it to work, any help with this would be appreciated. edit: I've also tried UpdateSourceTrigger=PropertyChanged and that didn't work either

  • Merging multiple docx files to one

    - by coding
    I am developing a desktop application in C#. I have coded a function to merge multiple docx files but it does not work as expected. I don't get the content exactly as how it was in the source files. A few blank lines are added in between. The content extends to the next pages, header and footer information is lost, page margins gets changed, etc.. How can I concatenate docs as it is without and change in it.Any suggestions will be helpful. This is my code. public bool CombineDocx(string[] filesToMerge, string destFilepath) { Application wordApp = null; Document wordDoc = null; object outputFile = destFilepath; object missing = Type.Missing; object pageBreak = WdBreakType.wdPageBreak; try { wordApp = new Application { DisplayAlerts = WdAlertLevel.wdAlertsNone, Visible = false }; wordDoc = wordApp.Documents.Add(ref missing, ref missing, ref missing, ref missing); Selection selection = wordApp.Selection; foreach (string file in filesToMerge) { selection.InsertFile(file, ref missing, ref missing, ref missing, ref missing); selection.InsertBreak(ref pageBreak); } wordDoc.SaveAs( ref outputFile, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); return true; } catch (Exception ex) { Msg.Log(ex); return false; } finally { if (wordDoc != null) { wordDoc.Close(); } if (wordApp != null) { wordApp.DisplayAlerts = WdAlertLevel.wdAlertsAll; wordApp.Quit(); Marshal.FinalReleaseComObject(wordApp); } } }

  • Prevent WPF control from expanding beyond viewable area

    - by Dan dot net
    I have an Items Control in my user control with a scroll viewer around it for when it gets too big (Too big being content is larger than the viewable area of the user control). The problem is that the grid that it is all in just keeps expanding so that the scroll viewer never kicks in (unless I specify an exact height for the grid). See code below and thanks in advance. <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Height="300px"> <Grid.RowDefinitions> <RowDefinition Height="*" /> </Grid.RowDefinitions> <GroupBox FontWeight="Bold" Header="Tables" Padding="2"> <ScrollViewer> <ItemsControl FontWeight="Normal" ItemsSource="{Binding Path=AvailableTables}"> <ItemsControl.ItemTemplate> <DataTemplate> <CheckBox Content="{Binding Path=DisplayName}" IsChecked="{Binding Path=IsSelected}" Margin="2,3.5" /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </ScrollViewer> </GroupBox> </Grid> I would like to not specify the height.

  • UTF-8 support in java application

    I'm having trouble with UTF-8. common.jsp <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> typical.jsp <%@ include file="common.jsp" %> Page Head <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> Form <form id="screenObject" accept-charset="UTF-8" action="/SiteAdmin/articleHeaderEdit?articleId=15" method="post"> I enter non latin1 characters into a text field and click Save. Validator complains about another field and stops the submission. This never gets to the database, so database ability to handle UTF-8 is not in this picture. The page redisplays with appropriate error but the text that had been entered is all messed up. All non latin1 characters are converted to some gibberish. I'm using Spring 3 MVC, in case that matters... Attempts Adding this to my view resolver didn't help: <property name="contentType" value="text/html;charset=UTF-8" />

    i am not sure if my design have flaw but would like to know what others have to say, i am in a situation where i am trying to acheive two things in one click. using : asp.net web form i have a web form with few textbox and a gridview control and a button. if i click on the button i am executing two things 1) asynchronously get data from server to client (working great) and able to display the data in the textboxes. 2) same click i want to bind the gridview. <asp:Content ID="Content2" ContentPlaceHolderID="cphMaster" runat="server"> <asp:Label runat="server" ID='Label1' >Id:</asp:Label> <asp:TextBox ID="txtId" runat='server'></asp:TextBox> <asp:Button ID="btnSubmit" OnClientClick="LoadDataById();" runat="server" Text="Submit" onclick="btnSubmit_Click" /> <br /> <br /> <asp:TextBox ID="txtName" runat='server'></asp:TextBox> <br /> <asp:TextBox ID="txtPurpose" runat='server'></asp:TextBox> <br /> <br /> <asp:GridView ID="GridView1" runat="server"> </asp:GridView> </asp:Content> server side protected void btnSubmit_Click(object sender, EventArgs e) { GridView1.DataSource = laodData(int.Parse(txtId.Text)); GridView1.DataBind(); } Jquery: function LoadVisitBasicByVisitId() { ContactServiceProxy.invoke({ serviceMethod: "GetDataById", data: { request: request }, callback: function(response) { processCompletedContactStore(response); }, error: function(xhr, errorMsg, thrown) { postErrorAndUnBlockUI(xhr, errorMsg, thrown); } }); return false; } recap: 1) jquery script execute asynchronously to get data from server to client and display in the textboxes 2) server side code to bind the gridview.

  • Problem with PHP localeconv() - Maybe UTF-8

    - by Chuck Ugwuh
    I'm having an issue with the localeconv() in PHP. I'm using a Windows PC. I set my locale to France using setLocale(LC_ALL, 'fra_fra') function. Then I call the localeconv() function to a variable. When I output that variable, below is what I get. Array ( [decimal_point] = , [thousands_sep] = ? [int_curr_symbol] = EUR [currency_symbol] = ? [mon_decimal_point] = , [mon_thousands_sep] = ?

I've done the following: Set my default_charset in PHP.ini to UTF-8 The Content-type on my page is UTF-8 I've also called same in a header i.e. header('Content-type: text/html; charset=utf-8') I'm using firefox and changed the charset there too, still no luck I also updated my http.conf file with AddDefaultCharset, but still no cigar I'm completely stumped and not sure what next to do. Can anyone help out? Thanks.

  • What am I doing wrong with my ItemsControl & databinding?

    - by Joel
    I'm reworking my simple hex editor to practice using what I've recently learned about data binding in WPF. I'm not sure what I'm doing wrong here. As I understand it, for each byte in the collection "backend" (inherits from ObservableCollection), my ItemsControl should apply the DataTemplate under resources. This template is just a textbox with a binding to a value converter. So I'm expecting to see a row of textboxes, each containing a string representation of one byte. When I use this XAML, all I get is a single line of uneditable text, which as far as I can tell doesn't use a textbox. What am I doing wrong? I've pasted my XAML in below, with the irrelevant parts (Menu declaration, schema, etc) removed. <Window ...> <Window.Resources> <local:Backend x:Key="backend" /> <local:ByteConverter x:Key="byteConverter" /> <DataTemplate DataType="byte"> <TextBox Text="{Binding Converter={StaticResource byteConverter}}" /> </DataTemplate> </Window.Resources> <StackPanel> <ItemsControl ItemsSource="{Binding Source={StaticResource backend}}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapPanel /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </StackPanel> </Window>

  • How to get the recently viewed pictures on the web browser?

    - by quantity
    I want to retrieve the recently viewed pictures from IE. I know that all the files from IE exist in the internet temporary directory, commonly with the path like "C:\Documents and Settings[account]\Local Settings\Temporary Internet Files". Here something strange for me comes. I wrote a program of C++ to retrieve the directory above, and the result says it contains three subdirectories and one file. These subdirectories are Content.IE5, OIS, and OLK145, each contains lots of pictures, which I think are the ones I browsed recently on the web. The only file is desktop.ini, which is not my concern. However, when I open the directory in the file system, there are no subdirectories at all, but a lot of files, different from the ones in the subdirectories retrieved by the program. I have several questions. Frist of all, why the content of the temorary internet files seems different? Which is the actual situation about the directory? Second, I found that in filesystem explorer, the files in the directory seem like some link to the ones on the web, not physically exist on my computer, is this true? Finally, how can I get the pictures viewed from IE recently with C++, as well as their original url?

  • How to create two columns on a web page?

    - by Roman
    I want to have two columns on my web page. For me the simples way to do that is to use a table: <table> <tr> <td> Content of the first column. </td> <td> Content of the second column. </td> </tr> </table> I like this solution because, first of all, it works (it gives exactly what I want), it is also really simple and stable (I will always have two columns, no matter how big is my window). It is easy to control the size and position of the table. However, I know that people do not like the table-layout and, as far as I know, they use div and css instead. So, I would like also to try this approach. Can anybody help me with that? I would like to have a simple solution (without tricks) that is easy to remember. It also needs to be stable (so that it will not accidentally happen that one column is under another one or they overlap or something like that).

  • Google Sites API - File Cabinets: Spaces and extension separator (.) are removed from file names

    - by user1299447
    We have a series of internal reports that we update regularly from our internal databases. We built an application in C# that uploads these reports to a Google Site. Everything works fine, except that the name of the file shown to the final user in the File Cabinet does not include the original spaces nor the extension separator (.) For example, Stock per warehouse.pdf is shown as : Stockperwarehousepdf Below is a simplified version of the code. private AtomEntry UploadAttachment(string filename, AtomEntry parent, string title, string description) { SiteEntry entry = new SiteEntry(); AtomCategory category = new AtomCategory(SitesService.ATTACHMENT_TERM, SitesService.KIND_SCHEME); category.Label = "attachment"; entry.Categories.Add(category); AtomLink parentLink = new AtomLink(AtomLink.ATOM_TYPE, SitesService.PARENT_REL); parentLink.HRef = parent.SelfUri; entry.Links.Add(parentLink); entry.MediaSource = new MediaFileSource(filename, MediaFileSource.GetContentTypeForFileName(filename)); entry.Content.Type = MediaFileSource.GetContentTypeForFileName(filename); entry.Title.Text= title; entry.Summary.Text = description; AtomEntry newEntry = null; newEntry = service.Insert(new Uri(makeFeedUri("content")), entry); } The key line is where the MediaFileSource object is created. Any idea of what we are missing? I've tried all sort of changes :(

    Hello. I need to recalculate body's main div height, than wait while all content (images) loads and only than show it to site visitor. To achieve this i used jQuery and CSS //CSS looks like body {display: none;} /* div block height calculator */ function recalculateHeight(id, add){ var height = $(id).height(); if (height < 650) height = 650; if (add) height = height + add; $('#left_div').height(height); $('#center_div').height(height); $('#right_div').height(height); } //recalculate height when page is fully loaded $(document).ready(function(){ $(window).load(function(){ $('body').show(); recalculateHeight("#center_div"); }); }); Everything works fine in IE, Firefox, Safari. In Chrome height calculation works, but seems that body doesn't hides, because all images loads as usual they should. In Opera, both functions doesn't work. Not page is showed when all content is loaded, not page calculation works. You would better understand what I am talking about: Site where this problem is Thanks for Your response, brgds

  • Should I really use a UITableView in this situation?

    - by mystify
    Imagine you have a view like this: At the top, there is an UISegmentedControl with two segments. It functions like a tab. Pressing one segment will activate this particular content below that UISegmentedControl. Below the UISegmentedControl are some switches. These modify the way how the content should be rendered. And finally, below those switches, there's a table. Imagine a table not in sense of UITableView, but just what it really is: A table. It shows little messages like twitter messages or chat messages for example, one below the other. Like you know it from skype and other chats. Basically they're just rows with some formatting. A label, some image views, some lines, a background. Pretty basic. The data comes from an array. No core data. The whole thing including the segmented control and setup switches must be scrollable. So what I did is: I put all this stuff in an UIScrollView. Now I have to make the decision if I would use a UITableView inside there for that table part, or if I would just print a lot of rows on to the scroll view (with -drawRect:). But some problems stick in my head: Can I put a UITableView inside a UIScrollView? I assume this makes a lot of problems. I don't want that the table part is separately scrollable. Again imagine that view: First there are some basic choice things (segmented control, switches). Then there comes the table. When you scroll, the whole thing scrolls. That's mainly because this first part with the settings can be pretty big, so you would want to scroll it away. The next thing is: Can I customize UITableView in such a way, that it consists of two parts? One for that settings part, and one for the actual data to display?

  • Are programming languages and methods ineffective? (assembler and C knowledge needed)

    - by b-gen-jack-o-neill
    Hi, for a long time, I am thinking and studying output of C language compiler in asemlber form, as well as CPU architecture. I know this may be silly to you, but it seems to me that something is very ineffective. Please, don´t be angry if I am wrong, and there is some reason I do not see for all these principles. I will be very glad if you tell me why is it designed this way. I actually trully believe I am wrong, I know the genius minds of people which get PCs together knew a reason to do so. What exactly, do you ask? I´ll tell you right away, I use C as a example: 1, Stack local scope memory allocation: So, typical local memory allocation uses stack. Just copy esp to ebp and than allocate all the memory via ebp. OK, I would understand this if you explicitly need allocate RAM by default stack values, but if I do understand it correctly, modern OS use paging as a translation layer between application and physical RAM, when adress you desire is further translated before reaching actuall RAM byte. So why don´t just say 0x00000000 is int a,0x00000004 is int b and so? And access them just by mov 0x00000000,#10? Becouse you wont actually access memory blocks 0x00000000 and 0x00000004 but those your OS set the paging tables to. Actually, since memory allocation by ebp and esp use indirect adressing, "my" way would be even faster. 2, Variable allocation duplicitly: When you run aaplication, Loader load its code into RAM. When you create variable, or string, compiler generates code that pushes these values on the top o stack when created in main. So there is actuall instruction for do so, and that actuall number in memory. So, there are 2 entries of the same value in RAM. One in fomr of instruction, second in form of actuall bytes in the RAM. But why? Why not to just when declaring variable count at which memory block it would be, than when used, just insert this memory location?

  • sending address of a variable declared on the stack?

    - by kobac
    I have a doubt concerning declaring variables, their scope, and if their address could be sent to other functions even if they are declared on the stack? class A{ AA a; void f1(){ B b; aa.f2(&b); } }; class AA{ B* mb; f2(B* b){ mb = b; //... } }; Afterwards, I use my AA::mb pointer in the code. So things I would like to know are following. When the program exits A::f1() function, b variable since declared as a local variable and placed on the stack, can't be used anymore afterwards. What happens with the validity of the AA::mb pointer? It contains the address of the local variable which could not be available anymore, so the pointer isn't valid anymore? If B class is a std::<vector>, and AA::mb is not a pointer anymore to that vector, but a vector collection itself for example. I would like to avoid copying all of it's contents in AA::f2() to a member AA::mb in line mb = b. Which solution would you recommend since I can't assign a pointer to it, because it'll be destroyed when the program exits AA::f2()

We need to get all <a href=""></a> tags which DO NOT contain img tag inside it. <a href="http://domain1.com"><span>Here is link</span></a> <a href="http://domain2.com" title="">Hello</a> <a href="http://domain3.com" title=""><img src="" /></a> <a href="http://domain4" title=""> I'm the image <img src="" /> yeah</a> I'm using this regular expression to find out all links preg_match_all("!<a[^>]+href=\"?'?([^ \"'>]+)\"?'?[^>]*>(.*?)</a>!is", $content, $out); I can modify it preg_match_all("!<a[^>]+href=\"?'?([^ \"'>]+)\"?'?[^>]*>([^<>]+?)</a>!is", $content, $out); But how can I tell to exclude results containing <img substring inside of <a href=""></a>? Thank you

    I did exactly the same thing, but still the same error is occurring: "The tag 'CenterToolTipConverter' does not exist in XML namespace 'clr-namespace:WpfApplication1;assembly=WpfApplication1'. Line 12 Position 10." CenterToolTipConverter.cs namespace WpfApplication1 { public class CenterToolTipConverter : IMultiValueConverter { public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture) { if (values.FirstOrDefault(v => v == DependencyProperty.UnsetValue) != null) { return double.NaN; } double placementTargetWidth = (double)values[0]; double toolTipWidth = (double)values[1]; return (placementTargetWidth / 2.0) - (toolTipWidth / 2.0); } public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture) { throw new NotSupportedException(); } } } MainWindow.xaml <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1;assembly=WpfApplication1" Title="MainWindow" Height="350" Width="525"> <Window.Resources> <local:CenterToolTipConverter x:Key="myCenterToolTipConverter"/> </Window.Resources> </Window> What am I doing wrong? Thanks in advance!!!
