  • Android: Playing an audio clip onClick

    - by fordays
    How do I set up an audiofile to play when a user touches an image. Where should I store the audio file and what code should I use to actually play the file? I don't want to bring up the MediaPlayer interface or anything like that. I was thinking of doing it like this: foo = (ImageView)this.findViewById(R.id.foo); foo.setOnClickListener(this); public void onClick(View v) { if (foo.isTouched()) { playAudioFile(); } } Thanks

  • Displaying xaml resources dynamically?

    - by Robert
    I used Mike Swanson's illustrator to xaml converter to convert some of my images to xaml. The convert creates a viewbox that contains the image. These viewboxes I made resource files in my program. The code below shows what I'm trying to do: I have a viewmodel that has an enum variable called PrimaryWinding of type Windings. The values PrimD and PrimY of the enum select the respective PrimD and PrimY xaml files in the resources. <UserControl.Resources> <DataTemplate x:Key="PrimTrafo" DataType="{x:Type l:Windings}"> <Frame Source="{Binding}" x:Name="PART_Image" NavigationUIVisibility="Hidden"> <Frame.LayoutTransform> <ScaleTransform ScaleX="0.5" ScaleY="0.5"/> </Frame.LayoutTransform> </Frame> <DataTemplate.Triggers> <DataTrigger Binding="{Binding}" Value="PrimD"> <Setter TargetName="PART_Image" Property="Source" Value="Resources\PrimD.xaml" /> </DataTrigger> <DataTrigger Binding="{Binding}" Value="PrimY"> <Setter TargetName="PART_Image" Property="Source" Value="Resources\PrimY.xaml" /> </DataTrigger> </DataTemplate.Triggers> </DataTemplate> </UserControl.Resources> <!--The contentcontrol that holds the datatemplate defined above--> <Grid > <Grid.ColumnDefinitions> <ColumnDefinition Width="2*"></ColumnDefinition> <ColumnDefinition Width="2*"></ColumnDefinition> <ColumnDefinition Width="1*"></ColumnDefinition> </Grid.ColumnDefinitions> <ContentControl Grid.Column="0" Content="{Binding PrimaryWinding}" ContentTemplate="{StaticResource PrimTrafo}"/> </Grid> This code works. Only I can't resize the drawings to the size of the grid cell. I added the ScaleTransform class to resize the image. Is a Frame the wrong class to hold the drawings? Should I use the ScaleTransform class to resize the drawing to the size of the cell? And how can I do that dynamically?

  • How can I stop Flash from changing indent when user Clicks on hyperlink in TextField?

    - by Paul Chernoch
    I have a TextField which I initialize by setting htmlText. The text has anchor tags (hyperlinks). When a user clicks on the hyperlink, the indentation of the second and subsequent lines in the paragraph changes. Why? How do I stop it? My html has an image at the beginning of the line, followed by the tag, followed by more text. To style the hyper links to look blue always and underlined when the mouse is over them, I do this: var css:StyleSheet = new StyleSheet(); css.parseCSS("a {color: #0000FF;} a:hover {text-decoration: underline;}"); stepText.styleSheet = css; stepText.htmlText = textToUse; stepText.visible = true; Here is a fragment of the html text (with newlines and exrta whitespace added to improve readability - originally it was one long line): <textformat indent="-37" blockindent="37" > <img src="media/interface/level-1-bullets/solid-circle.png" align="left" hspace="8" vspace="1"/> American Dental Association. (n.d.). <i>Cleaning your teeth and gums (oral hygiene)</i>. Retrieved 11/24/08, from <a href="http://www.ada.org/public/topics/cleaning_faq.asp" target="_blank">http://www.ada.org/public/topics/cleaning_faq.asp </a> </textformat> <br/> As it turns out, the text field is of a width such that it wraps and the second line starts with "Retrieved 11/24/08". Clicking on the hyper link causes this particular line to be indented. Subsequent paragraphs are not affected. ASIDE: The image is a list bullet about 37 pixels wide. (I used images instead of li tags because Flash does not allow nested lists, so I faked it using a series of images with varying amounts of whitespace to simulate three levels of indentation.) IDEA: I was thinking of changing all hyperlinks to use "event:" as the URL protocol, which causes a TextEvent.LINK event to be triggered instead of following the link. Then I would have to open the browser in a second call. I could use this event handler to set the html text to itself, which might clear the problem. (When I switch pages in my application and then come back to the page, everything is OKAY again.) PROBLEM: If I use the "event:" protocol and user tries the right-mouse button click, they will get an error, or so I am told. (See http://www.blog.lessrain.com/as3-texteventlink-and-contextmenu-incompatibilities/ ) I do not like this trade-off.

  • How to register mouse_down on backpanel?

    - by ikky
    Hi. Here is an image to illustrate what i mean: http://img21.imageshack.us/img21/497/windowsmobilee.png I have one backpanel that listens to mouse_down event. Infront of that backpanel i have another panel(Overlaying panel), and a label in top. If i push the mousebutton on the label or the "Overlaying panel", nothing is registered. Is it possible to just make the backpanel listen for mouse actions, or do i have to create listeners for the other panel and label to? Thanks in advance

(I'm not a Flash programmer myself and it is rather hard to find out about what kind of unit Flash uses by googling for something like "flash font size"...) Ekeforshus

    Hi all, How do I programatically upload an XSLT file to an SSRS server database? I would like exactly the same functionality as the 'Upload File', preferably using the 'rs' command. I have tried rs.CreateResource, but it doesn't seem to work for XML/XSLT files (though it works for Excel and image files) I understand that manipulating the SSRS db is not supported. Thanks

    Hello Stack Anon, I have X number of image objects that I need to loop through in a view and want to create a new div every 6 objects or so (for a gallery). I have looked at cycle but it seems to change every other record. Does anyone know of a way to insert code into a view every 6 times? I could probably do it with nested loops but I am kinda stumped on this one. Thanks!

  • drupal (CMS) or codeigniter (MVC) for creating a new web application?

    - by ajsie
    im going to create a new web application that is very customized. it will contain images, that are fully searchable - in a very, very customized way. when you click on the pictures you can add comments and so on. it requires users to be registered, but the registration/login process will be highly customized too. at the moment im using CodeIgniter for this. But i've read a lot of posts about CMS like Drupal and it sounds like i could let it handle basic stuff, maybe design and other front end work. i have no experience with CMS, in fact, i just started to use a MVC framework like CI and was impressed of how much easier it gets to start developing. so i wonder, if i'm going to create this kind of application, could i use drupal and then add the usual stuff, as i was going to do with CodeIgniter, like controllers, views, models, config files, my own libraries and so on? how does it work on a system like Drupal. how do you code PHP with it as with any MVC framework. it sounds like it has a lot of modules, i just wonder, if i can use it as a MVC framework but have the benefit of having all these basic stuff and design ready to use? cause then it sounds like the best "library" to provide for a web application from scratch. or is it difficult to create a customized app with it? i guess it has modules like images and users, but then how could i customize these so that every image has tags on it and country information, or have every user subscribing to changes to an image, that email will be sent to users and so on? cause i guess its easy to install a module. the question is, how do i customize it. maybe i don't need all that table columns. maybe i want to add/remove business logic. what are the pros and cons with using Drupal for this? is it even the right way to go? can you make a Stackoverflow with Drupal? Facebook? Twitter? Youtube? assuming that you know php of course. share your thoughts cause im totally new on creating a web application! thanks

  • Custom cell in list in Flash AS3

    - by Stian Flatby
    I am no expert in Flash, and I need some quick help here, without needing to learn everything from scratch. Short story, I have to make a list where each cell contains an image, two labels, and a button. List/Cell example: img - label - label - button img - label - label - button As a Java-programmer, I have tried to quicly learn the syntax and visualness of Flash and AS3, but with no luck so far. I have fairly understood the basics of movie clips etc. I saw a tutorial on how to add a list, and add some text to it. So I dragged in a list, and in the code went list.addItem({label:"hello"}); , and that worked ofc. So i thought if I double-clicked the MC of the list, i would get to tweak some things. In there I have been wandering around different halls of cell-renderers etc. I have now come to the point that I entered the CellRenderer_skinUp or something, and customized it to my liking. When this was done, I expected i could use list.addItem(); and get an empty "version" of my cell, with the img, labels and the button. But AS3 expects an input in addItem. From my object-oriented view, I am thinking that i have to create an object of the cell i have made, but i have no luck reaching it.. I tried to go var test:CellRenderer = list.listItem; list.addItem(test); ..But with no luck. This is just for funsies, but I really want to make this work, however not so much that I am willing to read up on ALOT of Flash and AS3. I felt that I was closing in on the prize, but the compiler expected a semicolon after the variable (list.addItem({test:something});). Note: If possible, I do NOT want this: list.addItem({image:"src",label:"text",label"text",button:"text"}); Well.. It actually is what I want, but I would really like to custom-draw everything. Does anyone get what I am trying to do, and has any answers for me? Am I approaching this the wrong way? I have searched the interwebs for custom list-cells, but with no luck. Please, any guiding here is appreciated! Sti
