  • sql server mdf file database attachment

    - by jnsohnumr
    hello all i'm having a bear of a time getting visual studio 2010 (ultimate i think) to properly attach to my database. it was moved from original spot to #MYAPP#/#MYAPP#.Web/App_Data/#MDF_FILE#.mdf. I have three instances of sql server running on this machine. i have tried to replace the old mdf file with my new one and cannot get the connectionstring right for it. what i'm really wanting to do is to just open some DB instance, run a DB create script. Then I can have a DB that was generated via my edmx (generate database from model) in silverlight business application (c#) right now, when i go to server explorer in VS, choose add new connection, choose MS SQL Server Database FIle (SqlClient), choose my file location (app_data directory), use windows authentication, and hit the Test Connection button I get the following error: Unable to open the physical file "". Operating system error 5: "5(Access Denied.)". An attempt to attach to an auto-named database for file"" failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. The mdf file was created on the same machine by connecting to (local) on the sql server management studio, getting a new query, pasting in the SQL from the generated ddl file, adding a CREATE DATABASE [NcrCarDatabase]; GO before the pasted SQL, and executing the query. I then disconnected from the DB in management studio, closed management studio, navigated to the DATA directory for that instance, and copying the mdf and ldf files to my application's app_data folder. I am then trying to connect to the same file inside visual studio. I hope that gives more clarity to my problems :). Connection string is: Data Source=.\SQLEXPRESS;AttachDbFilename=C:\SourceCode\NcrCarDatabase\NcrCarDatabase.Web\App_Data\NcrCarDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True

  • Flash CS 4 / AS 2 + Dynamic Text + Html + Embedded fonts...

    - by AndreMiranda
    I have this scenario: 1) I have a dynamic text that receives its data from a XML. 2) The texts showed get theirs style from a CSS file. 3) My dynamic text has a html 'span' tag and it's formatted according to the CSS class that it's passed via the XML file. Ok... so far so good. It's something like: _root.txt.txtDica = "<span class='"+ node.childNodes[_global.auxCont].attributes.myStyle +"'>" + node.childNodes[_global.auxCont].attributes.myText+ "</span>"; The problem is that the swf has a poor quality text. So, I've been looking around, found some things about embedded fonts, Flash TextField() and etc. But, nothing seems to work. Does anyone know how can I generate this html tag in a dynamic text with a good quality? It's worth to say that I'm using regular fonts, such as Verdana and Arial. Thanks a lot!

  • jquery show / hide div on click even in a slideshow?

    - by KnockKnockWhosThere
    Is it possible to combine a slideshow and show / hide div functionality? My html structure is below, and basically, I'm trying to get the tabs a links to open up the div with the corresponding class if a user clicks on it. If a user doesn't click on it, it should still just cycle through each image. So, if the images are rotating, and I click on <a class="t2"> then would open. The thing is, it's unknown how many divs / tabs there will be, but they'll always be named t{n}. <div id="tab-content"> <div class="t1">content</div> <div class="t2">lorem ipsum</div> <div class="t3">knock knock</div> </div> <div id="nav"> <div id="tabs"> <ul> <li class="t1"><a class="t1" href="#">tab 1</a></li> <li class="t2"><a class="t2" href="#">tab 2</a></li> <li class="t3"><a class="t3" href="#">tab 3</a></li> </ul> </div> </div>

  • Defining default value in combobox in CakePHP

    - by Keyur
    <?php echo $form->create('admin_merchant_form', array('action' => '#')); echo $form->input('company_name', array('label' => 'Company Name')); echo $form->input('ac_owner', array('label' => 'Account Owner', 'options' => array('a','b','b'), 'default' => $merchant_select)); echo $form->end('Update'); ?> This is CakePHP code to generate a form with one combobox containing the values "a,b,c" and assigning the default value as $merchant_select which is numerical data. Now the problem is when I assign like 'default'=1 it returns 'b' in the combobox as default value but when writing 'default' = $merchant_select the combobox shows only the first value which is 'a'. The $merchant_select variable is assigned a numeric value equal to merchant's id which 1,2 or 3 when I select any row in the grid. And I also have JavaScript code which alerts with the merchant value when I select any row in the grid so the numeric data is definitely assigned to the $merchant_select variable.

  • JasperReports reports access image via authenticated URL

    - by user363115
    Hi all, I am hoping that this is a simple issue with a simple solution and that I have missed something obvious. Let me explain the problem; We have an application that generates PDF reports (using Jasper). These reports contain data from our database, as well as imagery (photographs). These photographs are stored in S3. We use signed URLs to access these photographs. We link these photographs into our Jasper reports using these S3 URLs. Because the S3 URLs are signed and time-limited (by design), the process is as follows; User requests a report to be generated, Report is filled, and goes to our database (at which time UUIDs to any required images are retrieved), For each UUID an S3 signed URL must be generated, To do this the URL behind each report image is a call to an authenticated URL in our app (/get_img?uuid=foo), The controller behind this URL generates a signed S3 URL and returns it, Reports loads the image. The problem is with step (4) - the call to the authenticated URL fails because Jasper does not pass any authentication information with the request. Is there a solution here? Thanks all for your time. Ben

  • problem in handling menu - submenu based on spring security

    - by Nirmal
    Hi All... I have configured spring security core plugin using requestmap table inside the database.. Now inside requestmap table I have all the possible urls and it's equivalent roles who can access that url... Now I want to generate menus and submenus based on the urls stored in requestmap table... So my requirement is to check the urls of menu & submenus against the logged in users privileges... And if logged in user has any one privilege then I need to display that main menu and the available submenus.... For e.g. I have a menu in my project called user which has a following submenus : **Users (main menu)** Manage Users (sub menu) Import Users (sub menu) Now inside my header.gsp I have successfully achieved the above requirement using if else condition, like : if ( privs.contains("/users/manageUsers") || privs.contains("/users/importUsers")) here privs are the list of urls from requestmap table for logged in user. But I want to achieve these using spring security tag lib, so for comparing urls I have find following tag from spring security core documentation : <sec:access url="/users/manageUsers"> But i am bit confuse that how I can replace or condition using tag library.. Is there any tag available which checks from multiple urls and evaluate it to true or false ? Of course I can do using sec:access tag with some flag logic, but is there any tags available which can fulfill my requirement directly ? Thanks in advance...

  • XSLT, worth investing time in, any actual alternatives?

    - by Keeno
    I realise this has been a few other questions on this topic, and people are saying use your language of choice to manipulate the xml etc etc however, not quite fit my question exactly. Firstly, the scope of the project: We want to develop platform independant e-learning, currently, its a bunch of HTML pages but as they grow and develop they become hard to maintain. The idea: Generate up an XML file + Schema, then produce some XSLT files that process the XML into the eLearning modiles. XML to HTML via XSLT. Why: We would like the flexibily to be able to easy reformat the content (i realise CSS is a viable alternative here) If we decide to alter the pages layout or functionality in anyway, im guessing altering the "shared" XSLT files would be easier than updating the HTML files. So far, we have about 30 modules, with up to 10-30 pages each Depending on some "parameters" we could output drastically different page layouts/structures, above and beyond what CSS can do Now, all this has to be platform independant, and to be able to run "offline" i.e. without a server powering the HTML Negatives ive read so far for XSLT: Overheard? Not exactly sure why...is it the compute power need to convert to HTML? Difficult to learn Better alternatives Now, what I would like to know exactly is: are there actually any viable alternatives for this "offline"? Am I going about it in the correct manner, do you guys have any advice or alternatives. Thanks!

  • Image swap with a javascript onclick dropdown menu

    - by AzzyDude
    So I've got this code that has an image and when you click it a dropdown menu appears. Pretty simple. The code works fine but I'm trying to incorporate an image swap on click and I'm having difficulty. Here's the HTML and the JS (there's some CSS too, but I'll leave that out): HTML: <div id="header"> <dl class="dropdown"> <dt><a href="#"><img src="images/cogwheel_btn.png"/></a></dt> <dd> <ul> <li><a href="#">Favorites</a></li> <li><a href="#">History</a></li> </ul> </dd> </dl> </div> JS: $(document).ready(function() { $(".dropdown img.flag").addClass("flagvisibility"); $(".dropdown dt a").click(function() { $(".dropdown dd ul").toggle(); }); $(".dropdown dd ul li a").click(function() { var text = $(this).html(); $(".dropdown dt a span").html(text); $(".dropdown dd ul").hide(); $("#result").html("Selected value is: " + getSelectedValue("sample")); }); function getSelectedValue(id) { return $("#" + id).find("dt a span.value").html(); } $(document).bind('click', function(e) { var $clicked = $(e.target); if (!$clicked.parents().hasClass("dropdown")) $(".dropdown dd ul").hide(); }); $("#flagSwitcher").click(function() { $(".dropdown img.flag").toggleClass("flagvisibility"); }); });? I've tried adding lines like ("dt").empty(); and then ("dt").html("new_image") but it causes the dropdown functionality to stop working. Anyone any ideas?

  • Invert the 1bbp color under a rectangle.

    - by Scott Chamberlain
    I am working with GDI+, the image I am working with is a 1bbp image. What i would like to do is draw a rectangle on the image and everything under that rectangle will be inverted (white pixels will become black and black pixels become white). All of the sample code I have seen is for 8 bit RGB color scale images, and I don't think the techniques they use will work for me. Here is the code I have so far. This is the parent control, one of the Epl2.IDrawableCommand's will be the command that does the inverting. protected override void OnPaint(PaintEventArgs e) { base.OnPaint(e); if (Label != null) { using (Bitmap drawnLabel = new Bitmap((int)((float)Label.LabelHeight * _ImageScaleFactor), (int)((float)Label.LableLength *(int) _ImageScaleFactor), System.Drawing.Imaging.PixelFormat.Format1bppIndexed)) { using (Graphics drawBuffer = Graphics.FromImage(drawnLabel)) { drawBuffer.ScaleTransform(_ImageScaleFactor, _ImageScaleFactor); foreach (Epl2.IDrawableCommand cmd in Label.Collection) { cmd.Paint(drawBuffer); } drawBuffer.ResetTransform(); } drawnLabel.RotateFlip(Rotation); pbLabelDrawArea.Size = drawnLabel.Size; using (Graphics drawArea = pbLabelDrawArea.CreateGraphics()) { drawArea.Clear(Color.White); drawArea.DrawImage(drawnLabel, new Point(0, 0)); } } } } What should I put in the Paint(Graphic g) for this command?

  • setting write permissions on theme subdirectory?

    - by Scott B
    I've a theme which supports multiple templates, each with a header background image whose color can be set by the site owner via a colorpicker widget in my theme's options panel. This has the effect of opening the background image, recoloring it and resaving it back to the server. I've had zero issues with this routine until recently when a customer installed the theme on a web host whose default read/write permissions are apparently much more restrictive than the norm. In this case, the user was unable to alter the colors of the template images because of the permissions settings. I'm looking for a bit of understanding on what the permissions would need to be (assuming I purposefully set them via script) to allow the logged in wordpress user to write to files under my theme's styles directory. The code I'm using to write to the image file is below... $img = imagecreatefromgif("../wp-content/themes/mytheme/styles/".get_option('my_theme')."/image.gif"); $color = imagecolorallocate($img, $info["red"], $info["green"], $info["blue"]); imagecolorset($img, 0, $info["red"], $info["green"], $info["blue"]); imagegif($img, $path);

  • Why does my Android App crash when loading image from gallery the 2nd time?

    - by Sebastian
    Hi folks, I've written an app, thats loading images either using the android gallery app or by taking a photo using the cam. When I now load an image using the gallery, everything is fine. When the code is being executed a second time (for loading another image), the application crashes. try { Uri data = intent.getData(); ContentResolver cr = this.getContentResolver(); Bitmap mBitmap = null; mBitmap = Media.getBitmap(cr, data); imageView.setImageBitmap(mBitmap); } catch(Exception e){ showToast(this, "Failed loading image from gallery"); return; } The code crashes at the line mBimap = Media.getBitmap(cr, data);. Everything is initialized, there are no null values etc. The strange thing is: no exception is thrown, I don't get into the catch block to determine whats going wrong. Does anyone have an idea about this? Am I not allowed to "re-use" the content resolver? Do I have to free it after the first usage or something like this?

  • ColdFusion Session issue - multiple users behind one proxy IP -- cftoken and cfid seems to be shared

    - by smoothoperator
    Hi Everyone, I have an application that uses coldfusion's session management (instead of the J2EE) session management. We have one client, who has recently switched their company's traffic to us to come viaa proxy server in their network. So, to our Coldfusion server, it appears that all traffic is coming from this one IP Address, for all of the accounts of this one company.. Of the session variables, Part 1 is kept in a cflock, and Part 2 is kept in editable session variables. I may be misundestanding, but we have done it this way as we modify some values as needed throughout the application's usage. We are now running into an issue of this client having their session variables mixed up (?). We have one case where we set a timestamp.. and when it comes time to look it up, it's empty. From the looks of it this is happening because of another user on the same token. My initial thoughts are to look into modifying our existing session management to somehow generate a unique cftoken/cfid, or to start using jsession_ID, if this solves the problem at all. I have done some basic research on this issue and couldn't find anything similar, so I thought I'd ask here. Thanks!

  • jQuery class selectors with nested div's

    - by mboles57
    This is part of some HTML from which I need to retrieve a piece of data. The HTML is assigned to a variable called fullDescription. <p>testing</p> <div class="field field-type-text field-field-video-short-desc"> <div class="field-label">Short Description:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Demonstrates the basics of using the Content section of App Cloud Studio </div> </div> </div> <div class="field field-type-text field-field-video-id"> <div class="field-label">Video ID:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> 1251462871001 </div> </div> </div> I wish to retrieve the video ID number (1251462871001). I was thinking something like this: var videoID = $(fullDescription).find(".field.field-type-text.field-field-video-id").find(".field-item.odd").html(); Although it does not generate any syntax errors, it does not retrieve the number. Thanks for helping out a jQuery noob! -Matt

  • Flex/Actionscript image display problem.

    - by IanH
    I'm trying to extend the Image class but hit a problem that I can't get past. I have a private image (img) that loads an image and a function that takes that image and copies it onto the parent. The debug function "copyit2" displays the image fine (so I know it's loaded OK). But the function "copyit" doesn't work - it just displays a white rectangle. I can't see how to make copyit work so that the original image is copied to the BitmapData and then subsequenty copied onto the parent? (The idea is to do some processing on the Bitmap data before it is displayed, although this isn't shown here to keep the example simple.) I suspect it is something to do with the security of loading images, but I'm loading it from the same server as the application is run from - so this shouldn't be a problem? Thanks for any help anyone can provide. Ian package zoomapackage { import flash.display.Bitmap; import flash.display.BitmapData; import flash.display.Sprite; import flash.events.MouseEvent; import flash.geom.Matrix; import flash.geom.Point; import flash.geom.Rectangle; import flash.net.*; import mx.controls.Image; import mx.events.FlexEvent; public dynamic class Zooma extends Image { private var img:Image; public function copyit():void { var imgObj:BitmapData = new BitmapData(img.content.width, img.content.height, false); imgObj.draw(img); var matrix:Matrix = new Matrix(); this.graphics.beginBitmapFill(imgObj, matrix, false,true); this.graphics.drawRect(0, 0, this.width , this.height); this.graphics.endFill(); } public function copyit2():void { this.source = img.source; } public function Zooma() { super(); img = new Image(); img.load("http://localhost/Koala.jpg"); } } }

  • jQuery and Ajax

    - by Banderdash
    Can anyone help with a jQuery snippet that would use Ajax to pull an XML file in on page load? Have really clunky way of doing it without jQuery here: <script type="text/javascript"> function loadXMLDoc() { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { xmlDoc=xmlhttp.responseXML; var txt=""; x=xmlDoc.getElementsByTagName("title"); for (i=0;i<x.length;i++) { txt=txt + x[i].childNodes[0].nodeValue + "<br />"; } document.getElementById("checkedIn").innerHTML=txt; } } xmlhttp.open("GET","ajax-response-data.xml",true); xmlhttp.send(); } </script> Ideally rather the having a click generate the list it would do so on page load, showing the fields from the XML (title, author, and whether it is checked in or not i.e. <book id="#" checked-in="0">) Would hug you for a solution.

  • HTML, CSS: overbar matching square root symbol

    - by Pindatjuh
    Is there a way in HTML and/or CSS to do the following, but then correctly: √¯¯¯¯¯¯φ·(2π−γ) Such that there is an overbar above the expression, which neatly aligns with the &radic;? I know there is the Unicode &macr;, that looks like the overbar I need (as used in the above example, though as you can see – it doesn't align well with the root symbol). The solution I'm looking for works at least for one standard font, on most sizes, and all modern browsers. I can't use images; I'd like to have a pure HTML4/CSS way, without client scripting. Here is my current code, thank you Matthew Jones (+1) for the text-decoration: overline! Still some problems <div style="font-family: Georgia; font-size: 200%"> <span style="vertical-align: -15%;">&radic;</span><span style="text-decoration: overline;">&nbsp;x&nbsp;+&nbsp;1&nbsp;</span> </div> The line doesn't match the &radic; because I lowered it with 15% baseline height. (Because the default placement is not nice) The line thickness doesn't match the thickness of the &radic;. Thanks!

  • Finding the width of a directed acyclic graph... with only the ability to find parents

    - by Platinum Azure
    Hi guys, I'm trying to find the width of a directed acyclic graph... as represented by an arbitrarily ordered list of nodes, without even an adjacency list. The graph/list is for a parallel GNU Make-like workflow manager that uses files as its criteria for execution order. Each node has a list of source files and target files. We have a hash table in place so that, given a file name, the node which produces it can be determined. In this way, we can figure out a node's parents by examining the nodes which generate each of its source files using this table. That is the ONLY ability I have at this point, without changing the code severely. The code has been in public use for a while, and the last thing we want to do is to change the structure significantly and have a bad release. And no, we don't have time to test rigorously (I am in an academic environment). Ideally we're hoping we can do this without doing anything more dangerous than adding fields to the node. I'll be posting a community-wiki answer outlining my current approach and its flaws. If anyone wants to edit that, or use it as a starting point, feel free. If there's anything I can do to clarify things, I can answer questions or post code if needed. Thanks! EDIT: For anyone who cares, this will be in C. Yes, I know my pseudocode is in some horribly botched Python look-alike. I'm sort of hoping the language doesn't really matter.

Can I achieve this in a for loop or i need to use some thing else. Regards

  • Best way to migrate export/import from SQL Server to oracle

    - by matao
    Hi guys! I'm faced with needing access for reporting to some data that lives in Oracle and other data that lives in a SQL Server 2000 database. For various reasons these live on different sides of a firewall. Now we're looking at doing an export/import from sql server to oracle and I'd like some advice on the best way to go about it... The procedure will need to be fully automated and run nightly, so that excludes using the SQL developer tools. I also can't make a live link between databases from our (oracle) side as the firewall is in the way. The data needs to be transformed in the process from a star schema to a de-normalised table ready for reporting. What I'm thinking about is writing a monster query for SQL Server (which I mostly have already) that will denormalise and read out the data from SQL Server into a flat file using the sql server equivalent of sqlplus as a scheduled task, dump into a Well Known Location, then on the oracle side have a cron job that copies down the file and loads it with sql loader and rebuilds indexes etc. This is all doable, but very manual. Is there one or a combination of FOSS or standard oracle/SQL Server tools that could automate this for me? the Irreducible complexity is the query on one side and building indexes on the other, but I would love to not have to write the CSV dumping detail or the SQL loader script, just say dump this view out to CSV on one side, and on the other truncate and insert into this table from CSV and not worry about mapping column names and all other arcane sqlldr voodoo... best practices? thoughts? comments? edit: I have about 50+ columns all of varying types and lengths in my dataset, which is why I'd prefer to not have to write out how to generate and map each single column...

  • C++ Storing variables and inheritance

    - by Kaa
    Hello Everyone, Here is my situation: I have an event driven system, where all my handlers are derived from IHandler class, and implement an onEvent(const Event &event) method. Now, Event is a base class for all events and contains only the enumerated event type. All actual events are derived from it, including the EventKey event, which has 2 fields: (uchar) keyCode and (bool)isDown. Here's the interesting part: I generate an EventKey event using the following syntax: Event evt = EventKey(15, true); and I ship it to the handlers: EventDispatch::sendEvent(evt); // void EventDispatch::sendEvent(const Event &event); (EventDispatch contains a linked list of IHandlers and calls their onEvent(const Event &event) method with the parameter containing the sent event. Now the actual question: Say I want my handlers to poll the events in a queue of type Event, how do I do that? x Dynamic pointers with reference counting sound like too big of a solution. x Making copies is more difficult than it sounds, since I'm only receiving a reference to a base type, therefore each time I would need to check the type of event, upcast to EventKey and then make a copy to store in a queue. Sounds like the only solution - but is unpleasant since I would need to know every single type of event and would have to check that for every event received - sounds like a bad plan. x I could allocate the events dynamically and then send around pointers to those events, enqueue them in the array if wanted - but other than having reference counting - how would I be able to keep track of that memory? Do you know any way to implement a very light reference counter that wouldn't interfere with the user? What do you think would be a good solution to this design? I thank everyone in advance for your time. Sincerely, Kaa

It works fine in IE8 but Firefox and Chrome generate an error of 'sections.each is not a function' Here is the code: function getGroupOrder() { var sections = document.getElementsByClassName('section'); var alerttext = ''; sections.each(function(section) { var sectionID = section.id; var order = Sortable.serialize(sectionID); var mySectionID = Right(section.id); var myLen = String(Sortable.sequence(section)).length; var StuCode = ""; if (myLen ==8) {var StuCode = String(Sortable.sequence(section)).substring(myLen, 2);} else if (myLen ==9) {var StuCode = String(Sortable.sequence(section)).substring(myLen, 3);} alerttext += mySectionID + ': ' + StuCode + '\n'; alerttextb = sectionID + ': ' + StuCode + '\n'; } } One solution suggested on a forum "I was able to resolve this issue by wrapping the call to document.getElementsByClassName('section'); with $A()" but I don't have a clue what that means! I asked what it meant but the post was made in 2008 and no reply as yet. Thanks for any help provided. Regards

  • Call .NET Webservice with Android

    - by Lasse P
    Hi, I know this question has been asked here before, but I don't think those answers were adequate for my needs. We have a SOAP webservice that is used for an iPhone application, but it is possible that we need an Android specific version or a proxy of the service, so we have the option to go with either SOAP or JSON. I have a few concerns about both methods: SOAP solution: Is it possible to generate java source code from a WSDL file, if so, will it include some kind of proxy class to invoke the webservice and will it work in the Android environment at all? Google has not provided any SOAP library in Android, so i need to use 3rd party, any suggestion? What about the performance/overhead with parsing and transmitting SOAP xml over the wire versus the JSON solution? JSON solution: There is a few classes in the Android sdk that will let me parse JSON, but does it support generic parsing, like if I want the result to be parsed as a complex type? Or would I need to implement that myself? I have read about 2 libraries before here on Stackoverflow, GSON an Jackson. What is the difference performance and usability (from a developers perspective) wise? Do you guys have any experince with either of those libraries? So i guess the big question is, what method to go with? I hope you can help me out. Thanks in advance :-)

  • Dice Emulation - ImageView

    - by Michelle Harris
    I am trying to emulate dice using ImageView. When I click the button, nothing seems to happen. I have hard coded this example to replace the image with imageView4 for debugging purposes (I was making sure the random wasn't fail). Can anyone point out what I am doing wrong? I am new to Java, Eclipse and Android so I'm sure I've probably made more than one mistake. Java: import java.util.Random; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ImageView; import android.widget.Spinner; import android.widget.Toast; public class Yahtzee4Activity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Spinner s = (Spinner) findViewById(R.id.spinner); ArrayAdapter adapter = ArrayAdapter.createFromResource( this, R.array.score_types, android.R.layout.simple_spinner_dropdown_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); s.setAdapter(adapter); } public void onMyButtonClick(View view) { ImageView imageView1 = new ImageView(this); Random rand = new Random(); int rndInt = 4; //rand.nextInt(6) + 1; // n = the number of images, that start at index 1 String imgName = "die" + rndInt; int id = getResources().getIdentifier(imgName, "drawable", getPackageName()); imageView1.setImageResource(id); } } XML for the button: <Button android:id="@+id/button_roll" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/roll" android:onClick="onMyButtonClick" />
