  • jQuery, checking to see if video has height/width

    - by Mark
    I have a <video> element that is generated by js, and I need to get the height and width of it. var v = $('video'); v.height() returns null, because when it's run, the video hasn't yet been loaded, so no dimensions in the DOM. How do I check to see if the video has received a dimension, and if it hasn't, wait till it has to get the height and width. Thanks.

  • How to debug issues with differing execution times in different contexts.

    - by Dave
    The following question seems to be haunting me more consistently than most other questions recently. What kinds of things would you suggest I suggest that they look for when trying to debug "performance issues" like this? ok, get this - running this in query analyzer takes < 1 second exec usp_MyAccount_Allowance_Activity '1/1/1900', null, 187128 debugging locally, this takes 10 seconds: DataSet allowanceBalance = SqlHelper.ExecuteDataset( WebApplication.SQLConn(), CommandType.StoredProcedure, "usp_MyAccount_Allowance_Activity", Params); same parameters

  • Blob object not working properly even though the class is seralized

    - by GustlyWind
    I have class which is seralized and does convert a very large amount of data object to blob to save it to database.In the same class there is decode method to convert blob to the actual object.Following is the code for encode and decode of the object. private byte[] encode(ScheduledReport schedSTDReport) { byte[] bytes = null; try { ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(bos); oos.writeObject(schedSTDReport); oos.flush(); oos.close(); bos.close(); //byte [] data = bos.toByteArray(); //ByteArrayOutputStream baos = new ByteArrayOutputStream(); //GZIPOutputStream out = new GZIPOutputStream(baos); //XMLEncoder encoder = new XMLEncoder(out); //encoder.writeObject(schedSTDReport); //encoder.close(); bytes = bos.toByteArray(); //GZIPOutputStream out = new GZIPOutputStream(bos); //out.write(bytes); //bytes = bos.toByteArray(); } catch (Exception e) { _log.error("Exception caught while encoding/zipping Scheduled STDReport", e); } decode(bytes); return bytes; } /* * Decode the report definition blob back to the * ScheduledReport object. */ private ScheduledReport decode(byte[] bytes) { ByteArrayInputStream bais = new ByteArrayInputStream(bytes); ScheduledReport sSTDR = null; try { ObjectInputStream ois = new ObjectInputStream(bais); //GZIPInputStream in = new GZIPInputStream(bais); //XMLDecoder decoder = new XMLDecoder(in); sSTDR = (ScheduledReport)ois.readObject();//decoder.readObject(); //decoder.close(); } catch (Exception e) { _log.error("IOException caught while decoding/unzipping Scheduled STDReport", e); } return sSTDR; } The problem here is whenver I change something else in this class means any other method,a new class version is created and so the new version the class is unable to decode the originally encoded blob object. The object which I am passing for encode is also seralized object but this problem exists. Any ideas thanks

  • Preferences bundle -- iPhone vs. Simulator

    - by trevrosen
    I have a preferences bundle that exhibits different behavior in the simulator vs the phone. The basic problem is that the default values of my preferences are getting read fine on the simulator but are coming up NULL on the iPhone. Is there some kind of special initialization I have to do for the device in order for these to be seen there? Thanks in advance for any insights!

  • Switch activity from a AlertDialog button

    - by Fahim Ahmed
    Let's say , I have three classes : MapsActivity , MyItemizedOverlay & GetDirectionActivity . In MyItemizedOverlay , I want to switch to GetDirectionActivity after the positive dialog button is clicked . ActiveDialog is placed under onTap method , so that I can get the GeoPoint. For this , what I've done : In ItemizedOverlay class : @Override public boolean onTap(GeoPoint p, MapView mapView) { // TODO Auto-generated method stub int lat = p.getLatitudeE6(); int lot = p.getLongitudeE6(); AlertDialog.Builder dialog = new AlertDialog.Builder(mContext); dialog.setTitle("Confirmation"); dialog.setMessage("Confirm this as end point ?"); dialog.setPositiveButton("Yes", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int arg1) { // TODO Auto-generated method stub Intent intent = new Intent(mContext, GetDestination.class); startActivity(intent); } }); dialog.setNegativeButton("No", null); dialog.show(); return true ; } here IDE shows that I have a error in startActivity(intent) line . I've tried that also : In MyItemizedOverlay class : @Override public boolean onTap(GeoPoint p, MapView mapView) { return super.onTap(p, mapView); } In MapsActivity class : GeoPoint point2 = null ; confirmationOverlay.onTap(point2, mapView) ; int latt = point.getLatitudeE6() ; int longt = point.getLongitudeE6(); final int endpointArray [] = {latt , longt}; if(some condition to show the alert dialog after tapping) { AlertDialog.Builder dialog = new AlertDialog.Builder(MapsActivity.this); dialog.setTitle("Confirmation"); dialog.setMessage("Confirm this location as end point ?"); dialog.setPositiveButton("Yes", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int arg1) { // TODO Auto-generated method stub Intent intent = new Intent(MapsActivity.this,GetDestination.class); intent.putExtra("geopoint" , endpointArray); startActivity(intent); } }); dialog.setNegativeButton("No", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int arg1) { } }); dialog.show(); } For the if statement what sort of condition I can use ? If I set it just like lat0 then the alertdialog appears without tapping on the map. I know this is very silly , but since I am new in both android & java , I hope you guys will consider it. Please help !

  • ELMAH - Using custom error pages to collecting user feedback

    - by vdh_ant
    Hey guys I'm looking at using ELMAH for the first time but have a requirement that needs to be met that I'm not sure how to go about achieving... Basically, I am going to configure ELMAH to work under asp.net MVC and get it to log errors to the database when they occur. On top of this I be using customErrors to direct the user to a friendly message page when an error occurs. Fairly standard stuff... The requirement is that on this custom error page I have a form which enables to user to provide extra information if they wish. Now the problem arises due to the fact that at this point the error is already logged and I need to associate the loged error with the users feedback. Normally, if I was using my own custom implementation, after I log the error I would pass through the ID of the error to the custom error page so that an association can be made. But because of the way that ELMAH works, I don't think the same is quite possible. Hence I was wondering how people thought that one might go about doing this.... Cheers UPDATE: My solution to the problem is as follows: public class UserCurrentConextUsingWebContext : IUserCurrentConext { private const string _StoredExceptionName = "System.StoredException."; private const string _StoredExceptionIdName = "System.StoredExceptionId."; public virtual string UniqueAddress { get { return HttpContext.Current.Request.UserHostAddress; } } public Exception StoredException { get { return HttpContext.Current.Application[_StoredExceptionName + this.UniqueAddress] as Exception; } set { HttpContext.Current.Application[_StoredExceptionName + this.UniqueAddress] = value; } } public string StoredExceptionId { get { return HttpContext.Current.Application[_StoredExceptionIdName + this.UniqueAddress] as string; } set { HttpContext.Current.Application[_StoredExceptionIdName + this.UniqueAddress] = value; } } } Then when the error occurs, I have something like this in my Global.asax: public void ErrorLog_Logged(object sender, ErrorLoggedEventArgs args) { var item = new UserCurrentConextUsingWebContext(); item.StoredException = args.Entry.Error.Exception; item.StoredExceptionId = args.Entry.Id; } Then where ever you are later you can pull out the details by var item = new UserCurrentConextUsingWebContext(); var error = item.StoredException; var errorId = item.StoredExceptionId; item.StoredException = null; item.StoredExceptionId = null; Note this isn't 100% perfect as its possible for the same IP to have multiple requests to have errors at the same time. But the likely hood of that happening is remote. And this solution is independent of the session, which in our case is important, also some errors can cause sessions to be terminated, etc. Hence why this approach has worked nicely for us.

  • JVM missing Rhino

    - by Andrei
    I have a project that uses the ScriptEngine to process some javascript, and worked well on my machine, but when i send the projects's jar to the server, i had discovered that the server's JVM doesn't have Rhino built-in, returning null when the code calls a new ScriptEngineManager().getEngineByName("javascript"); I went to the rhino's download page, get the most recent version, and extracted the js.jar from it, added the jar on the project, but still have the same problem.
