  • Flash ActiveX: How to Load Movie from memory or resource or stream?

    - by yuku
    I'm embedding a Flash ActiveX control in my C++ app (Flash.ocx, Flash10a.ocx, etc depending on your Flash version). I can load an SWF file by calling LoadMovie(0, filename), but the file needs to physically reside in the disk. How to load the SWF from memory (or resource, or stream)? I'm sure there must be a way, because commercial solutions like f-in-box's feature Load flash movies from memory directly also uses Flash ActiveX control.

  • Android OnClick in ListView calling parent function

    - by user1321683
    I have an Android application with a ListView in it, the ListView will setup fine but now I want a image in the ListView to be clickable. I do this by using 2 classes, the Activity class (parent) and an ArrayAdapter to fill the list. In the ArrayAdapter I implement a OnClickListener for the image in the list that I want to be clickable. So far it all works. But now I want to run a function from the activity class when the onClick, for the image in the list, is run but I do not know how. Below are the 2 classes that I use. First the Activity class: public class parent_class extends Activity implements OnClickListener, OnItemClickListener { child_class_list myList; ListView myListView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // setup the Homelist data myList = new child_class_list (this, Group_Names, Group_Dates); myListView = (ListView) findViewById(R.id.list); // set the HomeList myListView.setAdapter( myList ); myListView.setOnItemClickListener(this); } void function_to_run() { // I want to run this function from the LiscView Onclick } public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // do something } } And the ArrayAdapter from where I want to call a function from the Activity class: public class child_class_list extends ArrayAdapter<String> { // private private final Context context; private String[] mName; private String[] mDate; public child_class_list (Context context, String[] Name, String[] Date) { super(context, R.layout.l_home, GroupName); this.context = context; this.mName = Name; this.mDate = Date; } @Override public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); View rowView = inflater.inflate(R.layout.l_home, parent, false); ImageView selectable_image = (ImageView) rowView.findViewById(R.id.l_selectable_image); selectable_image.setOnClickListener(new OnClickListener() { public void onClick(View v) { // I want to run the function_to_run() function from the parant class here } } ); // get the textID's TextView tvName = (TextView) rowView.findViewById(R.id.l_name); TextView tvDate = (TextView) rowView.findViewById(R.id.l_date); // set the text tvName.setText (mName[position]); tvDate.setText (mDate[position]); return rowView; } } If anyone knows how to run the function in the activity class from the arrayadapter or how to set the image onClickListener in the Activity Class I would greatly apriciate the help.

  • How can I speed up the rendering of my WPF ListBox?

    - by Justin Bozonier
    I have a WPF ListBox control (view code) and I am keeping maybe like 100-200 items in it. Every time the ObservableCollection it is bound to changes though it takes it a split second to update and it freezes the whole UI. Is there a way to add elements incrementally or something I can do to improve the performance of this control?

  • How to measure a canvas that has auto height and with

    - by Wymmeroo
    Hi Folks, I'm a beginner in silverlight so i hope i can get an answer that brings me some more light in the measure process of silverlight. I found an interessting flap out control from silverlight slide control and now I try to use it in my project. So that the slide out is working proper, I have to place the user control on a canvas. The user control then uses for itself the height of its content. I just wanna change that behavior so that the height is set to the available space from the parent canvas. You see the uxBorder where the height is set. How can I measure the actual height and set it to the border? I tried it with Height={Binding ElementName=notificationCanvas, Path=ActualHeight} but this dependency property has no callback, so the actualHeight is never set. What I want to achieve is a usercontrol like the tweetboard per example on Jesse Liberty's blog Sorry for my English writing, I hope you understand my question. <Canvas x:Name="notificationCanvas" Background="Red"> <SlideEffectEx:SimpleSlideControl GripWidth="20" GripTitle="Task" GripHeight="100"> <Border x:Name="uxBorder" BorderThickness="2" CornerRadius="5" BorderBrush="DarkGray" Background="DarkGray" Padding="5" Width="300" Height="700" > <StackPanel> <TextBlock Text="Tasks"></TextBlock> <Button x:Name="btn1" Margin="5" Content="{Binding ElementName=MainBorder, Path=Height}"></Button> <Button x:Name="btn2" Margin="5" Content="Second Button"></Button> <Button x:Name="btn3" Margin="5" Content="Third Button"></Button> <Button x:Name="btn1_Copy" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy1" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy2" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy3" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy4" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy5" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy6" Margin="5" Content="First Button"/> </StackPanel> </Border> </SlideEffectEx:SimpleSlideControl>

  • How can I include an external JavaScript file exactly once per partial view?

    - by AaronSieb
    I have a partial view (UserControl) that implements a simple pager in my Asp.Net MVC project. This pager needs access to a .js file that needs to be included exactly once, regardless of how many instances of the pager control are present on the parent page. I've tried to use Page.ClientScript.RegisterClientScriptInclude, but it had no effect (I assume because the code nugget was evaluated too late to impact the head control). Is there any simple alternative?
