  • Display fraction with numerator/denominator with empty fields for users to enter text

    - by Anil
    Hi all I have a scenario in which I need to design online keyboard with buttons implementing different mathematical functions in ASP.NET. For example 1) A button called "Fraction" Onclicking= should display A numerator and a denominator separated by '-' with empty fields. Just as we write fractions manually. Now when the user clicks on this button the cursor should focus on numerator displaying 'the division line' and then by pressing 'Down' arrow key(on computr keyboard) should focus on denominator allowing users to enter both fields. Keeping it simple the user should be able to toggle between numerator and denominator. Please help me with some sample code. I have got no idea. Thanks in advance

  • ASP.NET MVC Programming

    - by AlbertRosa
    So here's the deal I'm working on a project that I had originally focused on Zend Framework, But now I want to get into ASP.NET MVC and boy lets just say it's good and a great start though i'm still at the beginning stage of it. But I am having issues with passing Data From My Controller to the Master / Layout Page. Now in Zend I am able to determine which controller and which action I am in through a helper I created. Now I want to implement the same functionality in this ASP.NET MVC application. So my Master Layout Page knows which Controller I am in and hence highilighting the navigation for it. I am using a straight custom html li a structure navigation. Any help on this specific topic would be greatly appreciated.

  • Displaying an Image in an activity using URI

    - by evkwan
    Hi, I'm writing an application that uses Intent(MediaStore.ACTION_IMAGE_CAPTURE) to capture and image. On the process of capturing the image, I noted the output of the image's URI. Right after finishing the camera activity, I wish to display the image using this specific URI. The method I used to capture images is: private void saveFullImage() { Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); File file = new File(Environment.getExternalStorageDirectory(), "test.jpg"); outputFileUri = Uri.fromFile(file); intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); startActivityForResult(intent, TAKE_PICTURE); } Which is a method taken from Reto Meier's book Professional Android 2 Application Development. The method works fine, and I assume that the URI of the picture I just took is stored in the outputFileUri variable. Then at this point of the code is where I want to display the picture: @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == TAKE_PICTURE) { //I want to display the picture I just took here //using the URI } } I'm not sure how to do it. I tried creating a new layout object and a new ImageView object using the method setImageURI(outputFileUri). My main layout (xml) did not have a ImageView object. But even when I set the contentView to the new layout with the ImageView attached to it, it doesn't display anything. I tried creating a Bitmap object from the URI and set it to the ImageView, but I get an unexpected error and forced exit. I have seen examples from here here which creates a Bitmap from URI, but it's not displaying it? My question is just how to display an image in the middle of a running activity? Do I need to get the File Path (like this) in order to display it? If I make a Bitmap out of the URI, how do I display the Bitmap? I'm just probably missing something simple...so any help would be a greatly appreciated! Also additional question for thought: If I were to take multiple pictures, would you recommend me to use the SimpleCursorAdapter instead? Thanks!

  • LWJGL Circle program create's an oval-like shape

    - by N1ghtk1n9
    I'm trying to draw a circle in LWJGL, but when I draw I try to draw it, it makes a shape that's more like an oval rather than a circle. Also, when I change my circleVertexCount 350+, the shape like flips out. I'm really not sure how the code works that creates the vertices(I have taken Geometry and I know the basic trig ratios). I haven't really found that good of tutorials on creating circles. Here's my code: public class Circles { // Setup variables private int WIDTH = 800; private int HEIGHT = 600; private String title = "Circle"; private float fXOffset; private int vbo = 0; private int vao = 0; int circleVertexCount = 300; float[] vertexData = new float[(circleVertexCount + 1) * 4]; public Circles() { setupOpenGL(); setupQuad(); while (!Display.isCloseRequested()) { loop(); adjustVertexData(); Display.update(); Display.sync(60); } Display.destroy(); } public void setupOpenGL() { try { Display.setDisplayMode(new DisplayMode(WIDTH, HEIGHT)); Display.setTitle(title); Display.create(); } catch (LWJGLException e) { e.printStackTrace(); System.exit(-1); } glClearColor(0.0f, 0.0f, 0.0f, 0.0f); } public void setupQuad() { float r = 0.1f; float x; float y; float offSetX = 0f; float offSetY = 0f; double theta = 2.0 * Math.PI; vertexData[0] = (float) Math.sin(theta / circleVertexCount) * r + offSetX; vertexData[1] = (float) Math.cos(theta / circleVertexCount) * r + offSetY; for (int i = 2; i < 400; i += 2) { double angle = theta * i / circleVertexCount; x = (float) Math.cos(angle) * r; vertexData[i] = x + offSetX; } for (int i = 3; i < 404; i += 2) { double angle = Math.PI * 2 * i / circleVertexCount; y = (float) Math.sin(angle) * r; vertexData[i] = y + offSetY; } FloatBuffer vertexBuffer = BufferUtils.createFloatBuffer(vertexData.length); vertexBuffer.put(vertexData); vertexBuffer.flip(); vao = glGenVertexArrays(); glBindVertexArray(vao); vbo = glGenBuffers(); glBindBuffer(GL_ARRAY_BUFFER, vbo); glBufferData(GL_ARRAY_BUFFER,vertexBuffer, GL_STATIC_DRAW); glVertexAttribPointer(0, 2, GL_FLOAT, false, 0, 0); glBindBuffer(GL_ARRAY_BUFFER, 0); glBindVertexArray(0); } public void loop() { glClear(GL_COLOR_BUFFER_BIT); glBindVertexArray(vao); glEnableVertexAttribArray(0); glDrawArrays(GL_TRIANGLE_FAN, 0, vertexData.length / 2); glDisableVertexAttribArray(0); glBindVertexArray(0); } public static void main(String[] args) { new Circles(); } private void adjustVertexData() { float newData[] = new float[vertexData.length]; System.arraycopy(vertexData, 0, newData, 0, vertexData.length); if(Keyboard.isKeyDown(Keyboard.KEY_W)) { fXOffset += 0.05f; } else if(Keyboard.isKeyDown(Keyboard.KEY_S)) { fXOffset -= 0.05f; } for(int i = 0; i < vertexData.length; i += 2) { newData[i] += fXOffset; } FloatBuffer newDataBuffer = BufferUtils.createFloatBuffer(newData.length); newDataBuffer.put(newData); newDataBuffer.flip(); glBindBuffer(GL_ARRAY_BUFFER, vbo); glBufferSubData(GL_ARRAY_BUFFER, 0, newDataBuffer); glBindBuffer(GL_ARRAY_BUFFER, 0); } } 300 Vertex Count(This is my main problem) 400 Vertex Count - I removed this image, it's bugged out, should be a tiny sliver cut out from the right, like a secant 500 Vertex Count Each 100, it removes more and more of the circle, and so on.

  • Best practices for displaying large number of images as thumbnails in c#

    - by andySF
    I got to a point where it's very difficult to get answers by debugging and tracing object, so i need some help. What I'm trying to do: A history form for my screen capture pet project. The history must list all images as thumbnails (ex: picasa). What I've done: I created a HistoryItem:UserControl. This history item has a few buttons, a check box, a label and a picture box. The buttons are for delete/edit/copy image. The check box is used for selecting one or more images and the label is for some info text. The picture box is getting the image from a public property that is a path and a method creates a proportional thumbnail to display it when the control has been loaded. This user control has two public events. One for deleting the image and one for bubbling the events for mouse enter and mouse leave trough all controls. For this I use EventBroadcastProvider. The bubbling is useful because wherever I move the mouse over the control, the buttons appear. The dispose method has been extended and I manually remove the events. All images are loaded by looping a xml file that contains the path of all images. For each image in this XML I create a new HitoryItem that is added (after a little coding to sort and limit the amount of images loaded) to a flow layout panel. The problem: When I lunch the history form, and the flow layout panel is populated with my HistoryItem custom control, my memory usage increases drastically.From 14Mb to around 100MB with 100 images loaded. By closing the history form and disposing whatever I could dispose and even trying to call GC.Collect() the memory increase remain. I search for any object that could not be disposed properly like an image or event but wherever I used them they are disposed. The problem seams to be from multiple sources. One is that the events for bubbling are not disposing properly, and the other is from the picture box itself. All of this i could see by commenting all the code to a limited version when only the custom control without any image processing and even events is loaded. Without the events the memory consumption is reduced by axiomatically 20%. So my real question is if this logic, flow layout panels and custom controls with picture boxes, is the best solution for displaying large amounts of images as thumbnails. Thank you!

  • why don't more programming languages have builtin interfaces to the window manager?

    - by Naveen
    Programming is at the heart about automating tasks on a computer. Presumably those tasks would normally be done manually by a human. Humans use the computer through the keyboard, mouse, and interaction with the console or the window manager. But very few languages have built in functions that provide an interface to these basic computing objects. A notable exception is autohotkey, an open source language on windows, providing builtin functions that allow the following simple tasks: * Get Pixel Information * Get mouse position * Keyboard macros * Simulate key strokes * Simulate mouse click * Window management See examples on rosettacode. There have been various attempts on linux, many of which were stopped without explanation. One is the inactive tcl library: android. Search google code for android, lang:tcl

  • How to highlight ListView item on touch?

    - by AndroidNoob
    I have a simple ListView and I want each of it items to be highlighted on user's touch. I thought this should happen by default but it isn't. Can you advice? ListView xml: <ListView android:id="@+id/list_view" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:divider="#206600" android:dividerHeight="2dp" android:smoothScrollbar="true" android:background="#ffffff" > </ListView> And code of my Adapter: private class MyAdapter extends ArrayAdapter<Task> { private LayoutInflater mInflater; public MyAdapter(Context context, int resource, List<Task> list) { super(context, resource, list); mInflater = LayoutInflater.from(context); } @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { v = mInflater.inflate(R.layout.list_item, null); } Task task = taskList.get(position); /* Setup views from your layout using data in Object here */ return v; }

  • filter lists that are split by easylistsplitter.js?

    - by Jason
    Hi Everyone, At my site - jasondaydesign.com. I'm using easylistsplitter.js. I designed it this way, because I actually wanted a masonry.js style layout but I couldn't find a way to filter divs. So I made the switch to lists, and found a plugin that allowed me to have a masonry style layout. Unfortunately, I have tried several list filters including: filterprojects.js and a netuts tutorial on a filterable portfolio. Unfortunately, both work, but only on the first column. I can't seem to figure out a way to have a filter plugin work on all list items that have been split by easylistsplitter.js Thoughts?

I have baked the model lecturer (file) I have baked the controller lecturers_controller (file) I have baked the view lecturers (folder) I need to override the default layout but I want to add YUI 3 accordion sothat the table name lecturers will be on top, after clicking on the top division it will slidedown and will show me the column name of lecturer table. Is there anyone who could suggest me how to integrate the YUI 3 accordion - Do I have to write a helper for this or simply after copying the YUI 3 library I could code this in the default.ctp file. I am really confused as I could hardly get a full tutorial on this topic. Thank you in advance ................

  • IntelliJ Split Window Navigation

    - by jmquigley
    If I split the editor window (horizontal or vertical) into N tab groups, how do I switch/toggle from one tab group to another via the keyboard? If all of the tabs are in the same group you can switch from each tab easily (CTRL + right/left arrow), but when they're in separate tab groups I can't. I've searched through the key mappings and have not found one that seems to accomplish this. I know I can use the mouse, but I'm trying to find ways to avoid the mouse and stay with the keyboard. TIA for any help on this.

  • How to hide action bar before activity is created, and then show it again?

    - by Ilya Izhovkin
    I need to implements splash screen in my honeycomb app. I use this code in activity's onCreate to show splash: setContentView(R.layout.splash); getActionBar().hide(); and this code to show main UI after some time: setContentView(R.layout.main); getActionBar().show(); But before onCreate is called and splash appears, there is small amount of time when action bar shown. How can I made it not to show? I tried to apply theme to activity without action bar: <item name="android:windowActionBar">false</item> but in that case getActionBar() always returns null and I found no way to show it again.

  • How do I attach an event handler to the document or window in GWT?

    - by Raph Levien
    In a GWT app centered around a canvas, I'm having trouble keeping focus directed in the right place - particularly for keyboard shortcuts. For now, I've wrapped the canvas in a FocusPanel, but that causes the canvas to not respond to the RequiresResize protocol, because FocusPanel does not plumb that. A second (related, I think) problem is that the FocusPanel is not getting Ctrl-A keypress events at all (tested on Mac Chrome). I can get Ctrl-Z and other keys (such as arrows) just fine. In a pure JavaScript world, I think the best answer to this would be to attach mouse and key handlers to the document or window object (I'm not positive which is better). However, I don't see an obvious way to do this in GWT - in particular, the Document and Window classes lack methods for attaching these kind of event handlers? Anyone know how to do it, or, perhaps, to solve the more general problem of keeping focus on an appropriate widget able to handle keyboard shortcuts?

  • How can I run an android frame animation without it skewing?

    - by GameDev123
    I have a small state machine that runs a series of frame by frame animations in an ImageView, in a nested hierarchy of layouts. There is more than adequate space to display each frame of the animation. Each frame of the animation is cropped to fit the minimum amount of area, in order to save memory. If a frame only contains 50x50 worth of pixels then the png is 50x50. There is no transparent padding to keep them the same size. The ImageView is directly within a RelativeLayout, and is anchored to the bottom left with some padding. The general idea being that the character in the animation performs some action, which results in individual frames of the animation growing or shrinking. The issue is that individual frames of animation are skewed, and there does not appear to be any way of preventing this. If I set the source of the imageview directly to one of the frames of animation, it displays fine in the layout manager. I have tried this with Adjust View Bounds set to true, false, and undefined. I have tried using the background and the src attribute of imageview to set the animation drawable, I have tried every configuration of layout manager and setting minimum/maximum size that I can think of, and it still stretches the character on various frames depending on the size of the source png. In essence, all I want to do is say "I want this ImageView to anchor in the bottom left and then display any frame that happens to be in it without stretching or skewing it in any way aside from that which occurred when the frame png's were loaded." Seems simple, but I have yet to come across any way of doing it. Here is the layout of the imageview as of my last test, I had to remove bits of the XML to get it to display but nothing pertinent: RelativeLayout android:orientation="horizontal" android:layout_above="@+id/MenuOptions" android:layout_width="fill_parent" android:id="@+id/AnimationLayout" android:clipChildren="false" android:minHeight="180dp" android:layout_height="fill_parent" android:layout_below="@+id/GameBarLayout" ImageView android:id="@+id/animatedImg" android:layout_height="wrap_content" android:layout_width="wrap_content" android:visibility="visible" android:baselineAlignBottom="true" android:minHeight="180dp" android:minWidth="200dp" android:adjustViewBounds="true" android:layout_alignParentBottom="true" android:paddingLeft="30dp" android:paddingBottom="10dp" android:src="@drawable/idle01"/ImageView /RelativeLayout Here is how an animation is set up: animationDrawable = new AnimationDrawable(); animationDrawable.addFrame(res.getDrawable(R.drawable.idle01), 16); animationDrawable.addFrame(res.getDrawable(R.drawable.idle02), 16); animationDrawable.addFrame(res.getDrawable(R.drawable.idle03), 16);

  • git-svn clone checkouts wrong repo?

    - by hyperboreean
    So I am trying to switch to git, by using git-svn. I am having a svn repo called myrepo from which I want to clone just the project called myproject. The thing is that by running the following command: git svn clone path-to-repo/myrepo/myproject --stdlayout --prefix=svn myproject the whole repo myrepo is cloned rather than just myproject. I tried using -T, -t, -b as well to let git know about the layout of the project, but without any success. I always get the following output: Using higher level of URL: path-to-repo/myrepo/myproject => path-to-repo/myrepo and tries to clone that one. Am I doing something wrong? It might be that the svn repo layout could be broken or git incompatible ?

  • Problem with Refreshing data in ExpandableListView

    - by -providerivan.longin1
    Hi! My problem is when I want to refresh data in ExpandableListView while being in that current activity. I create adapter and when I want to add new data to list I call again constructor of that adapter(it is my private variable) with all new data....and then I call onContentChanged() method to redraw my list. But what happens is that I cant expand my list any more...like it is blocked or something and logcat isn't saying anything... This is the code that i call after setting new data in arraylists and maps: mAdapter = new MyExpandableListAdapter( this, groupData, R.layout.contact_list_parent, new String[] { NAME ,NUM_PHOTOS},//NUM_PHOTOS new int[] { R.id.rowText1, R.id.rowText2, R.id.photoAlbumImg }, childData, R.layout.contact_list_child, new String[] { NAME,NUM_PHOTOS}, //NUM_PHOTOS new int[] { R.id.rowText1, R.id.rowText2, R.id.photoAlbumImg } ); this.onContentChanged(); If anyone knows answer to this question please help me:) Thanks.

  • textFieldShouldBeginEditing + UIKeyboardWillShowNotification + OS 3.2

    - by user193545
    I have multiple textfields on a UIView. I resign for a previous textField in textFieldShouldBeginEditing method, where following sequence of events are performed UIKeyboardWillHideNotification is received corresponding to that field where the keyboard for the previous field is hidden. the method textFieldShouldBeginEditing returns a YES and then UIKeyboardWillShowNotification is received where the keyboard for the current field is displayed. However, in OS 3.2 even though textFieldShouldBeginEditing returns a YES, UIKeyboardWillShowNotification for the current field is not received. The logic works for OS < 3.2 Any ideas where I might be doing wrong?
