  • Pass elements of a list as arguments to a function in python

    - by Wilduck
    I'm building a simple interpreter in python and I'm having trouble handling differing numbers of arguments to my functions. My current method is to get a list of the commands/arguments as follows. args = str(raw_input('>> ')).split() com = args.pop(0) Then to execute com, I check to see if it is in my dictionary of command- code mappings and if it is I call the function I have stored there. For a command with no arguments, this would look like: commands[com]() However, if a command had multiple arguments, I would want this: commands[com](args[0],args[1]) Is there some trick where I could pass some (or all) of the elements of my arg list to the function that I'm trying to call? Or is there a better way of implementing this without having to use python's cmd class?

  • C# - How to override GetHashCode with Lists in object

    - by Christian
    Hi, I am trying to create a "KeySet" to modify UIElement behaviour. The idea is to create a special function if, eg. the user clicks on an element while holding a. Or ctrl+a. My approach so far, first lets create a container for all possible modifiers. If I would simply allow a single key, it would be no problem. I could use a simple Dictionary, with Dictionary<Keys, Action> _specialActionList If the dictionary is empty, use the default action. If there are entries, check what action to use depending on current pressed keys And if I wasn't greedy, that would be it... Now of course, I want more. I want to allow multiple keys or modifiers. So I created a wrapper class, wich can be used as Key to my dictionary. There is an obvious problem when using a more complex class. Currently two different instances would create two different key, and thereby he would never find my function (see code to understand, really obvious) Now I checked this post: http://stackoverflow.com/questions/638761/c-gethashcode-override-of-object-containing-generic-array which helped a little. But my question is, is my basic design for the class ok. Should I use a hashset to store the modifier and normal keyboardkeys (instead of Lists). And If so, how would the GetHashCode function look like? I know, its a lot of code to write (boring hash functions), some tips would be sufficient to get me started. Will post tryouts here... And here comes the code so far, the Test obviously fails... public class KeyModifierSet { private readonly List<Key> _keys = new List<Key>(); private readonly List<ModifierKeys> _modifierKeys = new List<ModifierKeys>(); private static readonly Dictionary<KeyModifierSet, Action> _testDict = new Dictionary<KeyModifierSet, Action>(); public static void Test() { _testDict.Add(new KeyModifierSet(Key.A), () => Debug.WriteLine("nothing")); if (!_testDict.ContainsKey(new KeyModifierSet(Key.A))) throw new Exception("Not done yet, help :-)"); } public KeyModifierSet(IEnumerable<Key> keys, IEnumerable<ModifierKeys> modifierKeys) { foreach (var key in keys) _keys.Add(key); foreach (var key in modifierKeys) _modifierKeys.Add(key); } public KeyModifierSet(Key key, ModifierKeys modifierKey) { _keys.Add(key); _modifierKeys.Add(modifierKey); } public KeyModifierSet(Key key) { _keys.Add(key); } }

  • Problem with From field in contact form and mail() function

    - by Matthew
    I've got a contact form with 3 fields and a textarea... I use jQuery to validate it and then php to send emails. This contact form works fine but, when I receive an email, From field isn't correct. I'd like to want that From field shows text typed in the Name field of the contact form. Now I get a From field like this: <[email protected]> For example, if an user types "Matthew" in the name field, I'd like to want that this word "Matthew" appears in the From field. This is my code (XHTML, jQuery, PHP): <div id="contact"> <h3 id="formHeader">Send Us a Message!</h3> <form id="contactForm" method="post" action=""> <div id="risposta"></div> <!-- End Risposta Div --> <span>Name:</span> <input type="text" id="formName" value="" /><br /> <span>E-mail:</span> <input type="text" id="formEmail" value="" /><br /> <span>Subject:</span> <input type="text" id="formSubject" value="" /><br /> <span>Message:</span> <textarea id="formMessage" rows="9" cols="20"></textarea><br /> <input type="submit" id="formSend" value="Send" /> </form> </div> <script type="text/javascript"> $(document).ready(function(){ $("#formSend").click(function(){ var valid = ''; var nome = $("#formName").val(); var mail = $("#formEmail").val(); var oggetto = $("#formSubject").val(); var messaggio = $("#formMessage").val(); if (nome.length<1) { valid += '<span>Name field empty.</span><br />'; } if (!mail.match(/^([a-z0-9._-]+@[a-z0-9._-]+\.[a-z]{2,4}$)/i)) { valid += '<span>Email not valid or empty field.</span><br />'; } if (oggetto.length<1) { valid += '<span>Subject field empty.</span><br />'; } if (valid!='') { $("#risposta").fadeIn("slow"); $("#risposta").html("<span><b>Error:</b></span><br />"+valid); $("#risposta").css("background-color","#ffc0c0"); } else { var datastr ='nome=' + nome + '&mail=' + mail + '&oggetto=' + oggetto + '&messaggio=' + encodeURIComponent(messaggio); $("#risposta").css("display", "block"); $("#risposta").css("background-color","#FFFFA0"); $("#risposta").html("<span>Sending message...</span>"); $("#risposta").fadeIn("slow"); setTimeout("send('"+datastr+"')",2000); } return false; }); }); function send(datastr){ $.ajax({ type: "POST", url: "contactForm.php", data: datastr, cache: false, success: function(html) { $("#risposta").fadeIn("slow"); $("#risposta").html('<span>Message successfully sent.</span>'); $("#risposta").css("background-color","#e1ffc0"); setTimeout('$("#risposta").fadeOut("slow")',2000); } }); } </script> <?php $mail = $_POST['mail']; $nome = $_POST['nome']; $oggetto = $_POST['oggetto']; $text = $_POST['messaggio']; $ip = $_SERVER['REMOTE_ADDR']; $to = "[email protected]"; $message = $text."<br /><br />IP: ".$ip."<br />"; $headers = "From: $nome \n"; $headers .= "Reply-To: $mail \n"; $headers .= "MIME-Version: 1.0 \n"; $headers .= "Content-Type: text/html; charset=UTF-8 \n"; mail($to, $oggetto, $message, $headers); ?>

  • POD global object initialization

    - by paercebal
    I've got bitten today by a bug. The following source can be copy/pasted (and then compiled) into a main.cpp file #include <iostream> // The point of SomeGlobalObject is for its // constructor to be launched before the main // ... struct SomeGlobalObject { SomeGlobalObject() ; } ; // ... // Which explains the global object SomeGlobalObject oSomeGlobalObject ; // A POD... I was hoping it would be constructed at // compile time when using an argument list struct MyPod { short m_short ; const char * const m_string ; } ; // declaration/Initialization of a MyPod array MyPod myArrayOfPod[] = { { 1, "Hello" }, { 2, "World" }, { 3, " !" } } ; // declaration/Initialization of an array of array of void * void * myArrayOfVoid[][2] = { { (void *)1, "Hello" }, { (void *)2, "World" }, { (void *)3, " !" } } ; // constructor of the global object... Launched BEFORE main SomeGlobalObject::SomeGlobalObject() { std::cout << "myArrayOfPod[0].m_short : " << myArrayOfPod[0].m_short << std::endl ; std::cout << "myArrayOfVoid[0][0] : " << myArrayOfVoid[0][0] << std::endl ; } // main... What else ? int main(int argc, char* argv[]) { return 0 ; } MyPod being a POD, I believed there would be no constructors. Only initialization at compile time. Thus, the global object SomeGlobalObject would have no problem to use the global array of PODs upon its construction. The problem is that in real life, nothing is so simple. On Visual C++ 2008 (I did not test on other compilers), upon execution myArrayOfPodis not initialized, even ifmyArrayOfVoid` is initialized. So my questions is: Are C++ compilers not supposed to initialize global PODs (including POD structures) at compilation time ? Note that I know global variable are evil, and I know that one can't be sure of the order of creation of global variables declared in different compilation units. The problem here is really the POD C-like initialization which seems to call a constructor (the default, compiler-generated one?). And to make everyone happy: This is on debug. On release, the global array of PODs is correctly initialized.

  • Import OLE Object from Access to MySQL

    - by SecretDeveloper
    I have a table in an access table which contains Product entries, one of the columns has a jpg image stored as an OLE Object. I am trying to import this table to MySQL but nothing seems to work. I have tried the MySQL migration tool but that has a known issue with Access and OLE Objects. (The issue being it doesnt work and leaves the fields blank) I also tried the suggestion on this site and while the data is imported it seems as though the image is getting corrupted in the transfer. When i try to preview the image i just get a binary view, if i save it on disk as a jpg image and try to open it i get an error stating the image is corrupt. The images in Access are fine and can be previewed. Access is storing the data as an OLE Object and when i import it to MySql it is saved in a MediumBlob field. Has anyone had this issue before and how did they resolve it ?

  • DataTable to Object collection

    - by Kenneth Cochran
    I'm working on a data import feature and I've been able to load an excel sheet into a DataTable using Ado.NET with the MSJet db engine. I created a simple one-to-one mapping dialog, in which the user drags column headings from their spreadsheet to a list of object properties. What's stumping me is how to turn each DataRow into a business object. Is there an easy way to do this? If there is a better way than using a DataTable as a middleman I'm open to suggestion? I use NHibernate extensively through out the rest of my program but I couldn't find any attempts to map to an excel spreadsheet. I went with a DataTable because the technique was well documented.

  • ASP.NET Call Another Element's DoPostBack Function

    - by blu
    I have an ASP.NET control that has an onclick event handler rendered inline on the element. I would like to call that function and have it raise the target control's server side event handler. <asp:CheckBox ID="Foo" runat="server" AutoPostBack="true" Text="Foo" /> <a href="#" onclick="javascript:setTimeout('__doPostBack(\'Foo\',\'\')', 0)">Test </a> I created the checkbox, looked at the rendered function on the field, and then copied that into the onclick on the anchor element. The anchor will raise a postback, but the event handler for the check box is not raised. protected override void OnLoad(EventArgs e) { // fires for checkbox // fires for anchor (the anchor does cause a postback) } void Foo_CheckedChanged(object sender, EventArgs e) { // fires for checkbox // does not fire for anchor } protected override void OnInit(EventArgs e) { this.Foo.CheckedChanged += new EventHandler(Foo_CheckedChanged); } Is it possible to do this?

  • Background problem of opengl 3d object over iphone camera view

    - by user292127
    Hi, I'm loading opengl 3d objects over the iphone camera view. When opengl view is loaded it's loading with a opengl 3d object with black background. The black background color will block the camera view.I just want to clear background color of opengl view so that I could load only the 3d object to the camera view. I had tried glclearcolor(1.0,1.0,1.0,0.0); but no change to background color. I had also tried to clear background color opengl view using [glview setbackgroundColor:[UIColor clearColor]];. No change in back ground color. Can any one help me with this stuff ? I'm new to opengl. Thanks in advance

  • Accessing the Custom Object Return type from ojdbc6 JDBC Thin Drivers

    - by Andrew Harmel-Law
    I'm writing some JDBC code which calls a Oracle 11g PL/SQL procdedure which has a Custom Object return type. I can get the code to call the procedure, but how do I access the returned Custom Object to obtain it's contained values?. An example of my code calling the procedure is below: PLSQL Code: Procedure GetDataSummary (p_my_key IN KEYS.MY_KEY%TYPE, p_recordset OUT data_summary_tab, p_status OUT VARCHAR2); Java Code: String query = "begin manageroleviewdata.getdatasummary(?, ?, ?); end;"); CallableStatement stmt = conn.prepareCall(query); stmt.setInt(1, 83); stmt.registerOutParameter(2, OracleTypes.ARRAY, "DATA_SUMMARY_TAB"); stmt.registerOutParameter(3, OracleTypes.VARCHAR); stmt.execute(stmt); How do I get the result back fron this?

  • Python Vector Class

    - by sfjedi
    I'm coming from a C# background where this stuff is super easy—trying to translate into Python for Maya. There's gotta' be a better way to do this. Basically, I'm looking to create a Vector class that will simply have x, y and z coordinates, but it would be ideal if this class returned a tuple with all 3 coordinates and if you could edit the values of this tuple through x, y and z properties, somehow. This is what I have so far, but there must be a better way to do this than using an exec statement, right? I hate using exec statements. class Vector(object): '''Creates a Maya vector/triple, having x, y and z coordinates as float values''' def __init__(self, x=0, y=0, z=0): self.x, self.y, self.z = x, y, z def attrsetter(attr): def set_float(self, value): setattr(self, attr, float(value)) return set_float for xyz in 'xyz': exec("%s = property(fget=attrgetter('_%s'), fset=attrsetter('_%s'))" % (xyz, xyz, xyz))

  • Object Dump JavaScript

    - by Jessy Houle
    Is there a 3rd party add-on/application or some way to perform object map dumping in script debugger for a JavaScript object? Here is the situation... I have a method being called twice, and during each time something is different. I'm not sure what is different, but something is. So, if I could dump all the properties of window (or at least window.document) into a text editor, I could compare the state between the two calls with a simple file diff. Thoughts? Thank you in advance. -Jessy Houle

  • Like Html.RenderAction() but without reinstantiating the controller object

    - by Jørn Schou-Rode
    I like to use the RenderAction extension method on the HtmlHelper object to render sidebars and the like in pages, as it allows me to keep the data access code for each such part in separate methods on the controller. Using an abstract controller base, I can define a default "sidebar strategy", which can then be refined by overriding the method in a concrete controller, when needed. The only "problem" I have with this approach, is that the RenderAction is built in a way where it always creates a news instance of the controller class, even when rendering actions from the controller already in action. Some of my controllers does some data lookup in their Initialize method, and using the RenderAction method in the view causes this to occur several times in the same request. Is there some alternative to RenderAction which will reuse the controller object if the action method to be invoked is on the same controller class as the "parent" action?

  • Convert JSON String to Java Object or HashMap

    - by Priyank
    Hi. I am writing an android app. I want to pass some data across the intents/activities and I feel that a conversion to and from JSON is probably a more optimal way at this point. I am able to convert a java hashmap to a json string successfully using JSONObject support. However i need to convert back this JSON string to a java object or a hashmap. What is the best way to go about it. Is parcelable really a change worth doing; if I have simple 5 field object? What are the other ways to transfer data between intents. Cheers

  • linker error in simple program: multiple definition of function

    - by BillyJean
    My function test is added to two different .cpp-files and the functions are private to their respective files as shown below test1.cpp #include <iostream> using namespace std; void test() { cout << "test" << endl; } test2.cpp #include <iostream> using namespace std; void test() { cout << "test" << endl; } main.cpp #include <iostream> using namespace std; int main() { return 0; } During linking I get the error multiple definition of test() - but how is that possible, considering that the two files have their own private scope!? I could understand it if I included the function prototype in each .cpp-files' corresponding header, but there is no such thing in this example.

  • Windows Store App Visual Basic Rotate Object with code

    - by Ajay Raghav
    How to rotate an ellipse (or any other object) with VB code? In XAML, I designed an ellipse and easily rotated it from the properties (Transform - Rotate - Angle). When I am trying to do it with VB code, I cannot locate the rotate/angle property of that ellipse. So, I tried this: Dim Rotator As RotateTransform Rotator.Angle = 90 Ellipse1.RenderTransform = Rotator It didn’t work. It says: Unable to cast object of type 'Windows.UI.Xaml.Media.MatrixTransform' to type 'Windows.UI.Xaml.Media.RotateTransform'. I think I’m close to the right way. Please give me a push. Thanks

  • Restlet/Jackson works differently when object implements Serializable

    - by ravyoli
    I am sending an object with some primitive fields using Restlet with Jackson converter. Up until now it worked great. But then I needed my object to implement Serializable, because I need to store it in memcache of GAE. For some reason - when the class implements Serializable, things stop working. Restlet sends a different string representation from before, and I can't even print that string in the server. I tried printing its byte value, char-by-char and the first numbers are: 0xfffd 0xfffd 0x0000 0x0005 0x0073 0x0072 Thanks a lot!

  • R how to find NA values after using addNA function

    - by screechOwl
    I have a data frame with a bunch of categorical variables. Some of them contain NA's and I use the addNA function to convert them to an explicit factor level. My problem comes when I try to treat them as NA's they don't seem to register. Here's my example data set and attempts to 'find' NA's: df1 <- data.frame(id = 1:200, y =rbinom(200, 1, .5), var1 = factor(rep(c('abc','def','ghi','jkl'),50))) df1$var2 <- factor(rep(c('ab c','ghi','jkl','def'),50)) df1$var3 <- factor(rep(c('abc','ghi','nop','xyz'),50)) df1[df1$var1 == 'abc','var1'] <- NA df1$var1 <- addNA(df1$var1) df1$isNaCol <- ifelse(df1$var1 == NA, 1, 0);summary(df1$isNaCol) df1$isNaCol <- ifelse(is.na(df1$var1), 1, 0);summary(df1$isNaCol) df1$isNaCol <- ifelse(df1$var1 == 'NA', 1, 0);summary(df1$isNaCol) df1$isNaCol <- ifelse(df1$var1 == '<NA>', 1, 0);summary(df1$isNaCol) Also when I type ??addNA I don't get any matches. Is this a gray-market function or something? Any suggestions would be appreciated.

  • Django view function design

    - by dragoon
    Hi, I have the view function in django that written like a dispatcher calling other functions depending on the variable in request.GET, like this: action = '' for act in ('view1', 'view2', 'view3', 'view4', ... ): if act in request.GET: action = act break ... if action == '': response = view0(request, ...) elif action == 'view1': response = view1(request, ...) elif action == 'view2': response = view2(request, ...) ... The global dispatcher function contains many variable initialization routines and these variables are then used in viewXX functions. So I feed that this is bad view design but I don't know how I can rewrite it?

  • Date javascript object from IE cannot be automatically bound to Datetime in ASP.NET MVC

    - by Sergio
    Hi There, I have a site that uses a jquery calendar to display events. I have noticed than when using the system from within IE (all versions) ASP.NET MVC will fail to bind the datetime to the action that send back the correct events. The sequence of events goes as follows. Calendar posts to server to get events Server ActionMethod accepts start and end date, automatically bound to datetime objects In every browser other than IE the start and end date come through as: Mon, 10 Jan 2011 00:00:00 GMT When IE posts the date, it comes through as Mon, 10 Jan 2011 00:00:00 UTC ASP.NET MVC 2 will then fail to automatically bind this to the action method parameter. Is there a reason why this is happening? The code that posts to the server is as follows: data: function (start, end, callback) { $.post('/tracker/GetTrackerEvents', { start: start.toUTCString(), end: end.toUTCString() }, function (result) { callback(result); }); },
