    - by I__
    i have this function: private string GetUSBComPort() { string[] sPorts = SerialPort.GetPortNames(); foreach (string port in sPorts) { if (port != "COM1" && port != "COM4") { return port; } } return null; } this function is being called from form load: private void Form1_Load(object sender, EventArgs e) { serialPort1 = new SerialPort(GetUSBComPort()); if (serialPort1.IsOpen) { serialPort1.Close(); } serialPort1.Open(); //ThreadStart myThreadDelegate = new ThreadStart(ReceiveAndOutput); //Thread myThread = new Thread(myThreadDelegate); //myThread.Start(); this.serialPort1.DataReceived += new SerialDataReceivedEventHandler(sp_DataReceived); } the function is unfortunately returning null how do i get the com port to which my phone is attached to via USB?

  • Java: How to make this Serializable?

    - by Hasslarn
    I dont know that much about Serializable, but i need this class to be. How to achieve it? package helpers; public class XY implements Comparable<XY> { public int x; public int y; public XY (int x, int y) { this.x = x; this.y = y; } public int compareTo( XY other ) { String compare1 = this.x + "-" + this.y; String compare2 = other.x + "-" + other.y; return compare1.compareTo( compare2 ); } public String toString() { return this.x + "-" + this.y; } } As of now i cant send it as an object with outputstream..I´ve tried just to implement Serializable but it doesnt do the trick!

  • How to use a function for every C# WinForm instead of pasting .

    - by nXqd
    protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { { if (keyData == Keys.Escape) this.Close(); return base.ProcessCmdKey(ref msg, keyData); } } I discovered this snippet to close windows form by esc. I really want to implement this to every windows form. I try to create a new abstract class which inherit from Form and another windows form will inherit from this one . But it doesn't work this way . abstract class AbsForm: Form { protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { { if (keyData == Keys.Escape) this.Close(); return base.ProcessCmdKey(ref msg, keyData); } } } public partial class HoaDonBanSach : AbsForm { public HoaDonBanSach() { InitializeComponent(); } Thanks for reading this :)

  • PHP: How do I access child properties from a method in a base object?

    - by Nick
    I'd like for all of my objects to be able to return a JSON string of themselves. So I created a base class for all of my objects to extend, with an AsJSON() method: class BaseObject { public function AsJSON() { $JSON=array(); foreach ($this as $key = $value) { if(is_null($value)) continue; $JSON[$key] = $value; } return json_encode($JSON); } } And then extend my child classes from that: class Package extends BaseObject { ... } So in my code, I expect to do this: $Box = new Package; $Box-SetID('123'); $Box-SetName('12x8x6'); $Box-SetBoxX('12'); $Box-SetBoxY('8'); $Box-SetBoxZ('6'); echo $Box-AsJSON(); But the JSON string it returns only contains the BaseClass's properties, not the child properties. How do I modify my AsJSON() function so that $this refers to the child's properties, not the parent's?

The above method lags in IE and most of our user base use IE. Can someone help me. I figure the find() method is very expensive because of the DOM traversal and I am thinking of optimizing. Any ideas anyone? Thanks in advance :D Been doing some profiling on the application and the following line seems to be causing alot of problems. help me please. is there any way I can optimize ? $('').append($('#cardDialogHelper').html()).addClass("card"); This is the ajax call that does the work. Is there a way to do some of this after the call. Please help me. (Added some functions I thought would be helpful in the diagnosis) GetAllPlansTemp = function() { $.getJSON("/SAMPLE/GetAllPlanItems",processData); } processData = function(data) { _throbber = showThrobber(); var sortedPlanItems = $(data.d).sort("Sequence", "asc"); // hideThrobber(_throbber); $(sortedPlanItems).each(createCardSkipTimelime); doCardStacks(); doTimelineFormat(); if (boolViewAblePlans == 'false') { $("p").show(); } hideThrobber(_throbber); } function createCardSkipTimelime() { boolViewAblePlans = 'false'; if (this.__Deleted == 'true' || IsPastPlanItem(this)) { return; } boolViewAblePlans = 'true'; fixer += "\n" + this.TempKey; // fixes what looks like a js threading issue. var value = CreatePlanCard2(this, GetPlanCardStackContainer(this.__type)); UpdatePlanCardNoTimeLine(value, this); } function CreatePlanCard2(carddata, sContainer) { var sCardclass = GetPlanCardClass(carddata.__type); var editdialog = getItemDialogContent(sCardclass); return $('<div/>').attr('id', carddata.TempKey).card({ 'container': $(sContainer), 'cardclass': sCardclass, 'editdialog': editdialog, 'readonly': GetCardMode(carddata) }); }

  • how to kill an older jsonp request?

    - by pfg
    I have a cross-domain long polling request using getJSON with a callback that looks something like this: $.getJSON("http://long-polling.com/some.fcgi?jsoncallback=?" function(data){ if(data.items[0].rval == 1) { // update data in page } }); The problem is the request to the long-polling service might take a while to return, and another getJSON request might be made in the meantime and update the page even though it is a stale response. Req1: h**p://long-polling.com/some.fcgi at 10:00 AM Req2: h**p://long-polling.com/some.fcgi? at 10:01 AM Req1 returns and updates the data on the page 10:02 AM I want a way to invalidate the return from Req1 if Req2 has already been made. Thanks!

  • averaging matrix efficiently

    - by user248237
    in Python, given an n x p matrix, e.g. 4 x 4, how can I return a matrix that's 4 x 2 that simply averages the first two columns and the last two columns for all 4 rows of the matrix? e.g. given: a = array([[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], [13, 14, 15, 16]]) return a matrix that has the average of a[:, 0] and a[:, 1] and the average of a[:, 2] and a[:, 3]. I want this to work for an arbitrary matrix of n x p assuming that the number of columns I am averaging of n is obviously evenly divisible by n. let me clarify: for each row, I want to take the average of the first two columns, then the average of the last two columns. So it would be: 1 + 2 / 2, 3 + 4 / 2 <- row 1 of new matrix 5 + 6 / 2, 7 + 8 / 2 <- row 2 of new matrix, etc. which should yield a 4 by 2 matrix rather than 4 x 4. thanks.

  • Passing URIs as URL arguments in Drupal 6

    - by wynz
    I'm running into problems trying to pass absolute URIs as parameters with clean URLs enabled. I've got hook_menu() set up like this: function mymodule_menu() { return array( 'page/%' = array( 'title' = 'DBpedia Display Test', 'page callback' = 'mymodule_dbpedia_display', 'page arguments' = array(1), ), ); } and in the page callback: function mymodule_dbpedia_display($uri) { // Make an HTTP request for this URI // and then render some things return $output; } What I'm hoping to do is somehow pass full URIs (e.g. "http://dbpedia.org/resource/Coffee") to my page callback. I've tried a few things and nothing's worked so far... http://mysite.com/page/http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Completely breaks Drupal's rewriting http://mysite.com/page/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Gives a 404 http://mysite.com/page/http://dbpedia.org/resource/Coffee Returns just "http:", which makes sense I could probably use $_GET to pull out the whole query string, but I guess I'm hoping for a more 'Drupal' solution. Any suggestions?

  • Returning and instance of a Class given its .class (MyClass.class)

    - by jax
    I have an enum that will hold my algorithms. I cannot instantiate these classes because I need the application context which is only available once the application has started. I want to load the class at runtime when I choose by calling getAlgorithm(Context cnx). How do I easily instantiate a class at runtime given its .class (and my constructor takes arguments)? All my classes are subclasses of Algorithm. public enum AlgorithmTypes { ALL_FROM_9_AND_LAST_FROM_10_ID(AlgorithmFactory.AlgorithmAllFrom9AndLastFrom10Impl.class), ALL_FROM_9_AND_LAST_FROM_10_CURRENCY_ID(AlgorithmFactory.AlgorithmAllFrom9AndLastFrom10Impl.class), DIVIDE_BY_9_LESS_THAN_100(AlgorithmFactory.AlgorithmAllFrom9AndLastFrom10Impl.class), TABLES_BEYOND_5_BY_5(AlgorithmFactory.AlgorithmAllFrom9AndLastFrom10Impl.class); private Class<? extends Algorithm> algorithm; AlgorithmTypes(Class<? extends Algorithm> c) { algorithm = c; } public Algorithm getAlgorithm(Context cnx) { return //needs to return the current algoriths constructor which takes the Context Algorithm(Context cnx); } }

  • Problem with optional arguments in C #defines

    - by imikedaman
    Hi, I'm having a problem with optional arguments in #define statements in C, or more specifically with gcc 4.2: bool func1(bool tmp) { return false; } void func2(bool tmp, bool tmp2) {} #define CALL(func, tmp, ...) func(tmp, ##__VA_ARGS__) int main() { // this compiles CALL(func2, CALL(func1, false), false); // this fails with: Implicit declaration of function 'CALL' CALL(func2, false, CALL(func1, false)); } That's obviously a contrived example, but does show the problem. Does anyone know how I can get the optional arguments to "resolve" correctly? Additional information: If I remove the ## before _VA_ARGS_, and do something like this: bool func2(bool tmp, bool tmp2) { return false; } #define CALL(func, tmp, ...) func(tmp, __VA_ARGS__) int main() { CALL(func2, false, CALL(func2, false, false)); } That compiles, but it no longer works with zero arguments since it would resolve to func(tmp, )

  • Shortcut to get all private field names combined with && operator as a generated line of code?

Let's say, I will enter "getAllPrivates&&" (or press a shortcut key) in the VS editor and it will return me something like this: private bool _privateFiel1 = false; private bool _privateFiel2 = true; private bool _privateFiel3 = false; private bool _privateFiel4 = false; private bool _privateFiel5 = true; // Here I press the shortcut or call the code-template and get his: _privateFiel1 && _privateFiel2 && _privateFiel3 && _privateFiel4 && _privateFiel5

I have some data types (classes) defined in Model B. I want to use them as return types for operations in Model A. However, I cannot figure out how to make the types defined in Model B show up in Model A when attempting to set return type on an operation. Any help/suggestions would be greatly appreciated!

  • Is throwing an exception a healthy way to exit?

    - by ramaseshan
    I have a setup that looks like this. class Checker { // member data Results m_results; // see below public: bool Check(); private: bool Check1(); bool Check2(); // .. so on }; Checker is a class that performs lengthy check computations for engineering analysis. Each type of check has a resultant double that the checker stores. (see below) bool Checker::Check() { // initilisations etc. Check1(); Check2(); // ... so on } A typical Check function would look like this: bool Checker::Check1() { double result; // lots of code m_results.SetCheck1Result(result); } And the results class looks something like this: class Results { double m_check1Result; double m_check2Result; // ... public: void SetCheck1Result(double d); double GetOverallResult() { return max(m_check1Result, m_check2Result, ...); } }; Note: all code is oversimplified. The Checker and Result classes were initially written to perform all checks and return an overall double result. There is now a new requirement where I only need to know if any of the results exceeds 1. If it does, subsequent checks need not be carried out(it's an optimisation). To achieve this, I could either: Modify every CheckN function to keep check for result and return. The parent Check function would keep checking m_results. OR In the Results::SetCheckNResults(), throw an exception if the value exceeds 1 and catch it at the end of Checker::Check(). The first is tedious, error prone and sub-optimal because every CheckN function further branches out into sub-checks etc. The second is non-intrusive and quick. One disadvantage is I can think of is that the Checker code may not necessarily be exception-safe(although there is no other exception being thrown anywhere else). Is there anything else that's obvious that I'm overlooking? What about the cost of throwing exceptions and stack unwinding? Is there a better 3rd option?

  • Dictionary w/ null key?

    - by Ralph
    Firstly, why doesn't Dictionary<TKey, TValue> support a single null key? Secondly, is there an existing dictionary-like collection that does? I want to store an "empty" or "missing" or "default" System.Type, thought null would work well for this. More specifically, I've written this class: class Switch { private Dictionary<Type, Action<object>> _dict; public Switch(params KeyValuePair<Type, Action<object>>[] cases) { _dict = new Dictionary<Type, Action<object>>(cases.Length); foreach (var entry in cases) _dict.Add(entry.Key, entry.Value); } public void Execute(object obj) { var type = obj.GetType(); if (_dict.ContainsKey(type)) _dict[type](obj); } public static void Execute(object obj, params KeyValuePair<Type, Action<object>>[] cases) { var type = obj.GetType(); foreach (var entry in cases) { if (entry.Key == null || type.IsAssignableFrom(entry.Key)) { entry.Value(obj); break; } } } public static KeyValuePair<Type, Action<object>> Case<T>(Action action) { return new KeyValuePair<Type, Action<object>>(typeof(T), x => action()); } public static KeyValuePair<Type, Action<object>> Case<T>(Action<T> action) { return new KeyValuePair<Type, Action<object>>(typeof(T), x => action((T)x)); } public static KeyValuePair<Type, Action<object>> Default(Action action) { return new KeyValuePair<Type, Action<object>>(null, x => action()); } } For switching on types. There are two ways to use it: Statically. Just call Switch.Execute(yourObject, Switch.Case<YourType>(x => x.Action())) Precompiled. Create a switch, and then use it later with switchInstance.Execute(yourObject) Works great except when you try to add a default case to the "precompiled" version (null argument exception).

  • Regular Expression to get the size value of a CSS property?

    - by thiesdiggity
    I wrote a regular expression to get the size from a CSS property: /(([+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i but for some reason its not working as intended. For example, when I run the following: preg_match_all('/(([+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i', "border-bottom:1px solid #99999;", $matches); It outputs: 1px 99999; But I only want the 1px value returned. I understand why its returning the above but can't seem to figure out how to only return the size and not the color value. I tried using the following negative lookbehind but it's not working either: /(((?<!#\d{3}|#\d{6})[+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i I want to use preg_match_all for those CSS properties that can have multiple size values (i.e. margin). Anyone have any ideas how to get this regex to return only the size values? Thanks for your help!
