    - by user287798
    Hi, i need someone to help me. I need a xaml with animated ellipses like the ones shown here:http://www.telerik.com/products/silverlight/chart.aspx They are to act as hotspot indicators on my map. What i have below is a xaml that i was trying to do but the circles don't center and have no fed-in/fade-out effect. May somebody help me please.

  • velocity vector

    - by wanderer
    Hi, I am trying to simulate a collision. The collision is shown here http://www.freeimagehosting.net/image.php?c5ae01b476.jpg A particle falls down on a sphere and a collision between sphere and particle takes place. The sphere always remain stationary and the collision itself is not elastic. So if the particle falls directly n top of sphere, the velocity of particle will become zero. I was trying to set the velocity of particle to be zero after the collision. But that does not give good simulation when the collision does not occur on top of sphere but along the side of sphere. So now after the collision i need to make sure that the particle has a velocity which is orthogonal to the vector of the point of collision from the center of sphere. The velocity along the vector from center of sphere to point of collision should become zero. How do i do that? I am a bit mathematically challenged but i think it has something to do with dot product of vectors. Or maybe i am wrong :) I have the initial velocity vector and 'radiusvector' say :- 1)velocity <-1.03054, -1.56563, 1.33341e-016 2) radius vector <2.04406, 2.19587, 1.0514 Pseudo code for the problem is: foreach( particle particle in particlesCollections) { //sphere.x, sphere.y sphere.z give the center of the sphere dist = particle.pos-vector(sphere.x,sphere.y,sphere.z); //detect if a collision has taken place. if (dist.mag < sphere.radius) { rVector=dist/dist.mag*sphere.radius; particle.pos=vector(sphere.x,sphere.y,sphere.z) + rVector; //particle.Velocity gives the velocity vector of the particle at the time of collision //i need to modify particle.Velocity so that the component of velocity that runs along // with the rvector becomes zero as i have a non elsatic collision. The remaining //velocity that the particle will have is the one which runs along with tangent to the //rVector. The sphere remains stationary. //example values: particle.Velocity == <-1.03054, -1.56563, .006> //and rVector = <2.04406, 2.19587, 1.0514> } } Thanks

  • How can I fill a rect with an alpha color using CoreGraphics?

    - by Rits Plasman
    In my drawRect method, I am drawing a PNG image. On top of that, I want to draw a rect with a 20% alpha color, like this: [[UIColor colorWithWhite:0.0 alpha:0.2] set]; UIRectFill(rect); The problem is, that the alpha property seems to get ignored. No alpha is applied at all, just a black rectangle is drawn. How can I fix this? Thanks in advance!

  • Silverlight: Set Items Widths in ItemsControl to Stretch

    - by Tom Allen
    I've got an ItemsControl which fills from top to bottom, but I can't get it's child items to occupy the whole width of the ItemsControl: I basically need to stretch the green bits to fill the width of the control (as shown by the blue bits). I've tried things like setting the HorizontalAlignment property of the template item to Stretch and I've even tried binding it's Width property to the ItemsControl Width, but neither worked. Should be a straight forward one, but it's something I just can't quite figure out...

  • Why html frame behave differently in Firefox and IE8 ?

    - by Frank
    I use html frame on my webiste, it's been running for I while, usually I only use Firefox to surf the net, my site looks and functions ok, but today I suddenly found IE8 has a problem with the frame on my site, if I click on the top menu items, it's supposed to display the content in the lower part of the frame, it does this correctly in Firefox, but in IE8, it displays the content in the upper part of the frame and replaces the menu items. In order to give more details, I'll include a simplified version of my html pages, at the top level there are two items, an index.html page and a file directory, all the pages except the index.html are in the directory, so it looks like this : index.html Dir_Docs 00_Home.html 00_Install_Java.html 00_Top_Menu.html 01_Home_Menu.html 01_Install_Java_Menu.html 10_Home_Welcome.html 10_How_To_Install_Java.html [ index.html ] <Html> <Head><Title>Java Applications : Tv_Panel, Java_Sound, Biz Manager and Web Academy</Title></Head> <Frameset Rows="36,*" Border=5 Bordercolor=#006B9F> <Frame Src=Dir_Docs/00_Top_Menu.html Frameborder=YES Scrolling=no Marginheight=1 Marginwidth=1> <Frame Src=Dir_Docs/00_Home.html Name=lower_frame Marginheight=1 Marginwidth=1> </Frameset> </Html> [ 00_Home.html ] <Html> <Head><Title>NMJava Application Development</Title></Head> <Frameset Cols="217,*" Align=center BorderColor="#006B9F"> <Frame Src=01_Home_Menu.html Frameborder=YES Name=side_menu Marginheight=1 Marginwidth=1> <Frame Src=10_Home_Welcome.html Name=content Marginheight=1 Marginwidth=1> </Frameset> </Html> [ 00_Install_Java.html ] <Html> <Head> <Title>Install Java</Title> </Head> <Frameset Cols="217,*" Align=center BorderColor="#006B9F"> <Frame Src=01_Install_Java_Menu.html Frameborder=YES Name=side_menu Marginheight=1 Marginwidth=1> <Frame Src=10_How_To_Install_Java.html Name=content Marginheight=1 Marginwidth=1> </Frameset> </Html> [ 00_Top_Menu.html ] <Html> <Head>Top Menu</Head> <Body> <Center> <Base target=lower_frame> <Table Border=1 Cellpadding=3 Width=100%> <Tr> <Td Align=Center Bgcolor=#3366FF><A Href=00_Home.html><Font Size=4 Color=White>Home</Font></A></Td> <Td Align=Center Bgcolor=#3366FF><A Href=00_Install_Java.html><Font Size=4 Color=White>Install Java</Font></A></Td> </Tr> </Table> </Center> </Body> </Html> [ 01_Home_Menu.html ] <Html> <Head><Title>Home Menu</Title></Head> <Base Target=content> <Body Bgcolor=#7799DD> <Center> <Table Border=1 Width=100%> <Tr><Td Align=center Bgcolor=#66AAFF><A Href=10_Home_Welcome.html>Welcome</A></Td></Tr> </Table> </Center> </Body> </Html> [ 01_Install_Java_Menu.html ] <Html> <Head><Title>Install Java</Title></Head> <Base Target=content> <Body Bgcolor=#7799DD> <Center> <Table Border=1 Width=100%> <Tr><Td Align=Center Bgcolor=#66AAFF><A Href=10_How_To_Install_Java.html>How To Install Java ?</A></Td></Tr> </Table> </Center> </Body> </Html> [ 10_Home_Welcome.html ] <Html> <Head><Title>NMJava For Software Development</Title></Head> <Body> <Center> <P> <Font Size=5 Color=blue>Welcome To NMJava For Software Development</Font> <P> </Center> </Body> </Html> [ 10_How_To_Install_Java.html ] <Html> <Head> <Title>Install Java</Title> </Head> <Body> <Center> <Br> <Font Size=5 Color=#0022AE><A Href=http://java.com/en/download/index.jsp>How To Install Java ?</A></Font> <Br> <P> <Table Width=90% Cellspacing=5 Cellpadding=5> <Tr><Td><Font Color=#0022AE> You need JRE 6 (Java Runtime Environment) to run the programs on this site.

  • Getting ImageView dimensions before adding the image

    - by twk
    I've got a RelativeLayout that contains these items: LinearLayout ImageView (weight = 1) LinearLayout So, the ImageView should expand and pin the other layouts on the top/bottom of the screen. I'm loading the ImageView using an image stored on a web server. However, I can fetch images of any size from the server, so I'd rather just fetch the exact image size I need. Thus, I need to get the size of the ImageView before I actually fill it in. How can I do this?

    I have an XMLList 'Keywords', which consists of about 30 XML items. I want to count the number of unique keywords in the List, and how often they occur. Then display the top 3 most occuring keywords. There's probably a simple sorting/count function to carry this out, however, i'm quite new to as3 so please forgive my naivety. Cheers.

  • Using gcc compiler flag in Xcode

    Hi, Shark has identified a area of code to be improved - Unaligned loop start and recommends adding -falign-loops=16 (gcc compiler flag). I've added this to Other C flags in iphone Xcode both to the dependant project and top level project. However it still does not seem to affect the performance and Shark is still reporting the same problem so it appears it didn't work. Am i doing this correctly?

  • PagerView overlapping PagerTabStrip / PagerTitleStrip

    - by user1256169
    I've been trying for about a week to get my PagerView not to overlap the TitleStrip. I've tried absolutely everything I can think of, and one StackOverflow question that looked like the same question, had an answer that wasn't applicable. It appears that both the PagerTitleStrip and the TextView start at 0,0 (left,top) Any help would be appreciated. Note that I can't use any XML (inc Layout.xml) so it's all done programatically. Here's a full working example of my problem: package com.example.projname; import android.app.Activity; import android.os.Bundle; import android.support.v4.view.PagerAdapter; import android.support.v4.view.PagerTabStrip; import android.support.v4.view.ViewPager; import android.view.Gravity; import android.view.View; import android.view.ViewGroup; import android.view.ViewGroup.LayoutParams; import android.widget.TextView; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); MyPagerAdapter myPagerAdapter = new MyPagerAdapter(); PagerTabStrip myPagerTabStrip = new PagerTabStrip(this); myPagerTabStrip.setGravity(Gravity.TOP); ViewPager viewPager = new ViewPager(this); viewPager.addView(myPagerTabStrip, LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); viewPager.setAdapter(myPagerAdapter); setContentView(viewPager); } class MyPagerAdapter extends PagerAdapter { public final String[] Titles = { "Title One", "Title Two", "Title Three", "Title Four", "Title Five" }; @Override public int getCount() { return Titles.length; } @Override public boolean isViewFromObject(View view, Object object) { return (view == object); } @Override public CharSequence getPageTitle(int position) { return Titles[position]; } @Override public Object instantiateItem(ViewGroup container, int position) { TextView textView = new TextView(getApplicationContext()); String myString = new String("Page " + (position + 1) + "\r\n"); textView.setText(myString + myString + myString + myString + myString + myString); container.addView(textView); return textView; } @Override public void destroyItem(ViewGroup container, int position, Object object) { container.removeView((View) object); } } } Edit: Adding a screenshot of the problem:

  • GPL liscensed frameworks on eccommerce websites

    - by Adam McMahon
    Ok this may be a foolish question, but I just want some clarification on this. If you build a website on a GPL licensed web framework, let's say a browser based game or some kind of kind of sophisticated web application are you required to redistribute all the code? If this is so what licenses would allow you to build on top of an opensource project without requiring you to redistribute the code?

  • ColdFusion MVC frameworks & RESTful Service mismatch?

    - by Henry
    Most CF MVC Frameworks use the front controller pattern. Usually Search Engine Safe (SES) plugin together with URL Rewrite are used to construct friendly URLs. However, when it comes to implementing RESTful services, using a MVC framework seems like a layer of complexity added on top of another layer of complexity. How should one tame this beast? Any nice and clean approach of supporting RESTful services with ColdFusion? Any MVC framework out there that can expose RESTful services easily? Thanks
