  • NSXMLParser on the iPhone, how do i use it given a xml file (newb here :\)

    - by Kenneth
    Hey guys, was wondering how do i use the NSXML parser. so lets say given i have a simple xml file with elements like 1/1/1000 14:15:16 How could i use the NSXMLParser to parse the XML File(Its on locally btw, desktop), check through each element and store each of them in an array either to be displayed/used later?

  • C# equivalent of NaN or IsNumeric

    - by johnc
    This seems like a fairly simple question, and I'm surprised not to have required it before. What is the most efficient way of testing a string input is a numeric (or conversely Not A Number). I guess I can do a Double.Parse or a regex (see below) public static bool IsNumeric(this string value) { return Regex.IsMatch(value, "^\\d+$"); } but I was wondering if there was a implemented way to do it, such as javascript's NaN() or IsNumeric() (was that VB, I can't remember).

  • ASP.NET Repeater and DataBinder.Eval

    - by Fernando
    I've got a <asp:Repeater> in my webpage, which is bound to a programatically created dataset. The purpose of this repeater is to create an index from A-Z, which, when clicked, refreshes the information on the page. The repeater has a link button like so: <asp:LinkButton ID="indexLetter" Text='<%#DataBinder.Eval(Container.DataItem,"letter")%>' runat="server" CssClass='<%#DataBinder.Eval(Container.DataItem, "cssclass")%>' Enabled='<%#DataBinder.Eval(Container.DataItem,"enabled")%>'></asp:LinkButton> The dataset is created the following way: protected DataSet getIndex(String index) { DataSet ds = new DataSet(); ds.Tables.Add("index"); ds.Tables["index"].Columns.Add("letter"); ds.Tables["index"].Columns.Add("cssclass"); ds.Tables["index"].Columns.Add("enabled"); char alphaStart = Char.Parse("A"); char alphaEnd = Char.Parse("Z"); for (char i = alphaStart; i <= alphaEnd; i++) { String cssclass="", enabled="true"; if (index == i.ToString()) { cssclass = "selected"; enabled = "false"; } ds.Tables["index"].Rows.Add(new Object[3] {i.ToString(),cssclass,enabled }); } return ds; } However, when I run the page, a "Specified cast is not valid exception" is thrown in Text='<%#DataBinder.Eval(Container.DataItem,"letter")'. I have no idea why, I have tried manually casting to String with (String), I've tried a ToString() method, I've tried everything. Also, if in the debugger I add a watch for DataBinder.Eval(Container.DataItem,"letter"), the value it returns is "A", which according to me, should be fine for the Text Property. EDIT: Here is the exception: System.InvalidCastException was unhandled by user code Message="Specified cast is not valid." Source="App_Web_cmu9mtyc" StackTrace: at ASP.savecondition_aspx._DataBinding_control7(Object sender, EventArgs e) in e:\Documents and Settings\Fernando\My Documents\Visual Studio 2008\Projects\mediTrack\mediTrack\saveCondition.aspx:line 45 at System.Web.UI.Control.OnDataBinding(EventArgs e) at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBind() at System.Web.UI.Control.DataBindChildren() InnerException: Any advice will be greatly appreciated, thank you EDIT 2: Fixed! The problem was not in the Text or CSS tags, but in the Enabled tag, I had to cast it to a Boolean value. The problem was that the exception was signaled at the Text tag, I don't know why

  • Create a timer countdown using hours, minutes & seconds from a future date

    - by Tommy Coffee
    I am using some code I found on the internet that creates a countdown from a certain date. I am trying to edit the code so that it only gives me a countdown from an hour, minute, and second that I specify from a future date. I cannot just have code that counts down from a specified time, I need it to countdown to a specified date in the future. This is important so that if the browser is refreshed the countdown doesn't start over but continues where left off. I will be using cookies so the browser remembers what future date was specified when it was first run. Here is the HTML: <form name="count"> <input type="text" size="69" name="count2"> </form> And here is the javascript: window.onload = function() { //change the text below to reflect your own, var montharray=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec") function countdown(yr,m,d){ var theyear=yr; var themonth=m; var theday=d var today=new Date() var todayy=today.getYear() if (todayy < 1000) todayy+=1900; var todaym=today.getMonth() var todayd=today.getDate() var todayh=today.getHours() var todaymin=today.getMinutes() var todaysec=today.getSeconds() var todaystring=montharray[todaym]+" "+todayd+", "+todayy+" "+todayh+":"+todaymin+":"+todaysec futurestring=montharray[m-1]+" "+d+", "+yr var dd=Date.parse(futurestring)-Date.parse(todaystring) var dday=Math.floor(dd/(60*60*1000*24)*1) var dhour=Math.floor((dd%(60*60*1000*24))/(60*60*1000)*1) var dmin=Math.floor(((dd%(60*60*1000*24))%(60*60*1000))/(60*1000)*1) var dsec=Math.floor((((dd%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1) if(dday==0&&dhour==0&&dmin==0&&dsec==1){ document.forms.count.count2.value=current return } else document.forms.count.count2.value= dhour+":"+dmin+":"+dsec; setTimeout(function() {countdown(theyear,themonth,theday)},1000) } //enter the count down date using the format year/month/day countdown(2012,12,25) } I am sure there is superfluous code above since I only need an hour, minute, and second that I would like to pass to the countdown() function. The year, month and day is unimportant but as I said this is code I am trying to edit which I found on the internet. Any help would be very appreciated. Thank you!

  • PHP's DOMXPath is stripping out my tags inside the matched text.

    - by Mint
    I asked this question yesterday, and at the time it was just what I needed, but while working with some live data I discovered that is wasn't quite doing what I expected. http://stackoverflow.com/questions/2571232/parse-html-with-phps-html-domdocument I gets the data from the HTML page, but then it also strips out all the HTML tags inside the captured block of text, which isn't what I want. (I might wan't to take some of the tags out, but not all, and this can be done later)

  • COM library for Explorer-like system views

    - by chrisd
    To provide a Windows Explorer-like view of the user's system, we have been using the shell controls from LogicNP (formerly Sky Software), but these have deficiencies, e.g., no support for Win7 libraries. The vendor has not responded to our inquiries about updates, so we're looking to replace the package. Requirements: ActiveX (no managed code or MFC) Tree and list views of the system Per-item checkboxes 32- and 64-bit versions Any recommendations for a replacement product? TIA.

  • Java IDE - find all INDIRECT usages/references of a function or class?

    - by GreenieMeanie
    In Netbeans or in Eclipse, you can use "Find Usages" or "References" from the right click context menu. If a() calls b(), using the functionality from b() will show you a(). However, what I want is to be able to see some kind of tree or have an option to see all usages of a given/class or method, such that if z() calls a() that using the functionality will show both z() and a(). Any IDE plugins or external tools that can do this?

  • How to calculate the time difference between two time fields , with respect to the date changes

    - by Tiru
    I want to calculate the time difference.I have three EditTexts , I want to input the times in the first two edittexts in HH:MM format. And then calculate the time difference and the result will show on third edittext field in same format. If the date changes, the time difference will calculate according that, i.e If first time = 23:00 and second time = 01:00 then, the time difference = 02:00 hours public class TimeCalculate extends Activity { private String mBlock; private String mBlockoff; private String mBlockon ; // String mHours, mMinutes; Date date1, date2; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); EditText blockoff = (EditText) findViewById(R.id.blockoff); mBlockoff = blockoff.getText().toString(); EditText blockon = (EditText) findViewById(R.id.blockon); mBlockon = blockon.getText().toString(); SimpleDateFormat simpleDateFormat = new SimpleDateFormat("hh:mm"); try { date1 = simpleDateFormat.parse(mBlockoff); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { date2 = simpleDateFormat.parse(mBlockon); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } mBlock = getDifference(date1, date2); EditText block = (EditText) findViewById(R.id.block); block.setText(mBlock.toString()); } public static String getDifference(Date startTime, Date endTime) { if (startTime == null) return "corrupted"; Calendar startDateTime = Calendar.getInstance(); startDateTime.setTime(startTime); Calendar endDateTime = Calendar.getInstance(); endDateTime.setTime(endTime); long milliseconds1 = startDateTime.getTimeInMillis(); long milliseconds2 = endDateTime.getTimeInMillis(); long diff = milliseconds2 - milliseconds1; /*int hours = (int)diff / (60 * 60 * 1000); int minutes = (int) (diff / (60 * 1000)); minutes = minutes - 60 * hours; long seconds = diff / (1000); */ //timeDiff = DateUtils.formatElapsedTime(seconds); SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:MM"); Date date = new Date(diff); return simpleDateFormat.format(date); } } I executed this code ,but gives error as Source not found.I think error at getDifference method.Please give any other logic

  • OpenGL: Implementing transformation matrix stack

    - by Jakub M.
    In a newer OpenGL there is no matrix stack. I am working on a simple display engine, and I am going to implement the transformation stack. What is a common strategy here? Should I build a push/pop stack, and use it with a tree representing my model? I suppose this is the "old" approach, that was deprecated in the newer OpenGL versions. Maybe then it is not the best solution (it was removed for some reason)

  • Basic Google search using a shell script

    Something like this but using just basic shell scripting: #!/usr/bin/env python import urllib import json base = 'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&' query = urllib.urlencode({'q' : "something"}) response = urllib.urlopen(base + query).read() data = json.loads(response) print data['responseData']['results'][0]['url'] Any more convenient alternatives to ajax.googleapis.com? If not, how should you encode the URL and parse JSON?
