  • Converting 'x' value of a CGPoint ivar to NSTimeInterval?

    - by eco_bach
    Hi I have a velocity ivar defined as a CGPoint. I need to somehow extract just the 'x' value of velocity, and then use this to call-send a message to the following method signature -(void) adjustTimer:(NSTimeInterval*)newInterval How do I obtain just the 'x' value of a CGPoint? Do I then need to convert or cast this result before calling my adjustTimer method?

  • Is arithmetic overflow/underflow generally checked in .Net framework methods?

    - by YWE
    For example, let's use the Add method of the ArrayList class. If I am using the default compiler settings in Visual Studio C# project in which arithmetic overflow is not checked, would ArrayList.Add() throw an OverflowException if I added too many items? Would surrounding the method call with checked or unchecked make any difference? BTW, I would write a test program to determine the answer to this question if I had Visual Studio available to me right now.

  • Reset selection of wx.lib.calendar.Calendar control?

    - by Joseph
    I have a wx.lib.calendar.Calendar control (not wx.lib.calendar.CalendarCtrl!). I am selecting a number of days using the following function call: self.cal.AddSelect([days], 'green', 'white') This works, and draws the days highlighted. However, I cannot work out how to reverse this (i.e., clear the selection so the days go back to their normal colouring). Any hints, please?

  • How to find out if an object is of <type> or a decendant of <type>

    - by Vaccano
    I have the following code: foreach (var control in this.Controls) { } I want to do something like control.Hide() in there. But the items in the this.Controls collection are not of type Control (they are Object). I can't seem to remember the safe way to cast this to call hide if it is really of type Control and do nothing otherwise. (I am a transplanted delphi programmer and I keep thinking something like control is Control.)

  • Is there a way to accumulate a commit message with git while examing changes?

    - by carleeto
    I use "git add -p" to stage my changes. What I'd like to be able to do is to accumulate a commit message as I'm examining my changes and then when I call "git commit", it is already filled out for me and allows me to make changes before I commit. Now, its easy to do with git gui by simply examining the changes and editing the commit message text box accordingly, but I'm a command line guy and was wondering if this is possible at the command line.

  • Calling overridden method from within overriding method in OO PHP

    - by paddymcc
    Working in a symfony model, I want to override a function and call the overridden function from within the overriding one, along the lines of class MyClass extends BaseMyClass { function setMyProperty($p) { parent::setMyProperty($p); //do some other stuff } } This is resulting in a segmentation fault. I don't want to alter the parent class - it's been generated by symfony, and may feasibly be overwritten in the future if the model is rebuilt. This seems like something that should be straightforward, but I'm struggling to find the solution. Thanks for any advice

  • Difference between chart, plot and graph

    - by Pradyumna
    I'm thinking of what would be the right terms to use in the UI of my new program, when referring to graphical data representations - i.e., whether to call them "charts", "plots" or "graphs". I was wondering how these terms are different, and when is it appropriate to use each of them? Thanks, Pradyumna

  • Is ArrayList.size() method cached?

    - by Peterdk
    I was wondering, is the size() method that you can call on a existing ArrayList<T> cached? Or is it preferable in performance critical code that I just store the size() in a local int? I would expect that it is indeed cached, when you don't add/remove items between calls to size(). Am I right?

  • C++ array initialization without assignment

    - by david
    This question is related to the post here. Is it possible to initialize an array without assigning it? For example, class foo's constructor wants an array of size 3, so I want to call foo( { 0, 0, 0 } ). I've tried this, and it does not work. I'd like to be able to initialize objects of type foo in other objects' constructor initialization lists. Is this possible?

  • Cocoa : How do I catch drag operations initiated from an IKBrowserView?

    - by bucketmouse
    So I've got an IKBrowserView all wired up and happily dragging my custom datatype (provided lazily via PasteboardItem) from one window to another, but now I'm interested in detecting when the user drops some data onto the trashcan. Cocoa's documentation says to check the return type of the drag operation itself, but how exactly do I do this with an IKBrowserView? Once I call imageBrowser:writeItemsAtIndexes:toPasteboard: I don't seem to get any notifications other than the request for the pasteboard contents, which doesn't provide a pointer to the drag operation that invoked it.

  • Get data from aspx.cs page to aspx page.

    - by Brad8118
    So I am using a jquery plug in that allows me to change the order of things in a list by dragging and dropping them. So my goal is to be able to grab a list of my objects (AlertInfo) and using it in a javascript function. I was able to use a json webservice call in a test project to pass the data to the page. But we don't have a webservice page now so I tried to grab it from a aspx.cs page and it hasn't worked. ///Aspx page: $.ajax({ type: "POST", url: "~/Alerts/GetAlerts", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { var data = eval("(" + msg.d + ")"); jQuery.each(data, function (rec) { AlertList[AlertList.length] = new objAlert(this.id, this.title, this.details, JSONDateSerializationFix(this.startdate), JSONDateSerializationFix(this.enddate)); UpdateDisplayList(); }) }, error: function (msg) { alert("BRAD" + msg); } The issue is that the Alerts page in "URL /Alerts/GetAlerts" is Alerts.aspx.cs. I can't figure out if I can use this ajax command to call a method in a aspx.cs page. //Code behind page aspx.cs [WebMethod] //[ScriptMethod(ResponseFormat = ResponseFormat.Json)] public string GetAlerts() { List list = AlertInfo.GetTestAlerts(); return new JavaScriptSerializer().Serialize(list); } public List GetAlertsList() { List list = AlertInfo.GetTestAlerts(); return list; ; } So I was hoping that I could load data into an asp control (dataList) and then grab the data //code behind page protected void Page_Load(object sender, EventArgs e) { dataListAlertList.DataSource = GetAlertsList(); dataListAlertList.DataBind(); } public static List<AlertInfo> GetTestAlerts() { List<AlertInfo> list = new List<AlertInfo>(); list.Add(new AlertInfo("0", "Alert 1 Title", "Alert 1 Detail", "10/10/2010", "10/10/2011")); list.Add(new AlertInfo("1", "Alert 2 Title", "Alert 2 Detail", "10/10/2010", "10/10/2011")); return list; } //.aspx page $(document).ready(function () { var a1 = $("#dataListAlertList").val(); // do fun stuff now. } But I keep getting undefined....

  • magento _redirect with parameters that have + or /

    - by epeleg
    seems like a call to $this->_redirect('*/*/myaction',$myargs); does not properly escape the arguments so if $myargs=array(p1=>'string that has + or / within it') the created URL will be something like: ..../myaction/?p1/string%20that%20has%20+%20or%20/%20within%20it causing the getParams collection on the action to have p1 with value 'string that has or ' <- plus sign missing and value broken and ' within it' with no value or something similar. is there any standard way I should handle the arguments before passing them to _redirect ?

  • Parsing returned array in javascript

    - by Dan
    I'm making a call to PayPal's credit card processor, and after a successful/unsuccessful transaction it returns me a string that looks like this: DoDirectPayment failed: Array ( [TIMESTAMP] = 2010%2d05%2d02T23%3a33%3a28Z [CORRELATIONID] = 8c503f5c6c861 [ACK] = Failure [VERSION] = 51%2e0 [BUILD] = 1268624 [L_ERRORCODE0] = 10527 [L_SHORTMESSAGE0] = Invalid%20Data [L_LONGMESSAGE0] = This%20transaction%20cannot%20be%20processed%2e%20Please%20enter%20a%20valid%20credit%20card%20number%20and%20type%2e [L_SEVERITYCODE0] = Error [AMT] = 90%2e00 [CURRENCYCODE] = USD ) I'm not a javascript pro, but how exactly can I turn that into a parseable array? Thank you!

  • Android Google maps co-ordinates

    - by Scoobler
    I have an app which stores co-ordinates. I am using Google maps to show the location to allow full use of the maps app. I am using the intent call and placing the co-ordinates in the q=xxxxxxxxx,xxxxxxxxx part. This works, however when Google maps shows the location it often finds a point on the road, sometimes a little distance from the actual co-ordinates. Is there a way to get maps to show the actual point?
