• Matlab GUI: How to Save the Results of Functions (states of application)

  - by niko

  Hi, I would like to create an animation which enables the user to go backward and forward through the steps of simulation. An animation has to simulate the iterative process of channel decoding (a receiver receives a block of bits, performs an operation and then checks if the block corresponds to parity rules. If the block doesn't correspond the operation is performed again and the process finally ends when the code corresponds to a given rules). I have written the functions which perform the decoding process and return a m x n x i matrix where m x n is the block of data and i is the iteration index. So if it takes 3 iterations to decode the data the function returns a m x n x 3 matrix with each step is stired. In the GUI (.fig file) I put a "decode" button which runs the method for decoding and there are buttons "back" and "forward" which have to enable the user to switch between the data of recorded steps. I have stored the "decodedData" matrix and currentStep value as a global variable so by clicking "forward" and "next" buttons the indices have to change and point to appropriate step states. When I tried to debug the application the method returned the decoded data but when I tried to click "back" and "next" the decoded data appeared not to be declared. Does anyone know how is it possible to access (or store) the results of the functions in order to enable the described logic which I want to implement in Matlab GUI?

• Help renaming svn repository

  - by rascher

  Here is the deal: I created an SVN repository, say, foo. It is at http://www.example.com/foo. Then I did an svn checkout. I made some updates and changes to my local copy of the code over the week. I haven't committed yet. I realized that I wanted to rename the repository. So I did this: svn copy http://example.com/foo http://example.com/bar svn delete http://example.com/foo I finish my changes (and local svn still thinks I'm working under "foo".) svn commit fails because the repo has been renamed. I try to use svn switch --relocate but it yells at me because svn is awful. I try using the script here to replace "foo" with "bar" in my billion .svn/ folders. This replace is taking a long time. I wonder if something hung? Or maybe sshfs failed? I kill it. Ctrl-C. I look and see that half my files have "foo" and the others have "bar" in the URLs in the sundry .svn/ folders. All I want to do is commit my files with the new name. I could re-checkout the branch, but then I have no way to remember which files I changed, which is why I was using version control in the first place, and svn is so godawful at moving and renaming things. What do I need to do to: Have a "clean" copy of my "bar" svn branch? and, most importantly: Commit the changes I made?

• can bind successfully to the ldap server, but needs to know how to find user w/i AD

  - by Brad

  I create a login form to bind to the ldap server, if successful, it creates a session (which the user's username is stored within), then I go to another page that has session_start(); and it works fine. What I want to do now, is add code to test if that user is a member of a specific group. So in theory, this is what I want to do if(username session is valid) { search ldap for user -> get list of groups user is member of foreach(group they are member of) { switch(group) { case STAFF: print 'they are member of staff group'; $access = true; break; default: print 'not a member of STAFF group'; $access = false; break; } if(group == STAFF) { break; } } if($access == TRUE) { // you have access to the content on this page } else { // you do not have access to this page } } How do I do a ldap_search w/o binding? I don't want to keep asking for their password on each page, and I can't pass their password thru a session. Any help is appreciated.

• C++ variable to const expression

  - by user1344784

  template <typename Real> class A{ }; template <typename Real> class B{ }; //... a few dozen more similar template classes class Computer{ public slots: void setFrom(int from){ from_ = from; } void setTo(int to){ to_ = to; } private: template <int F, int T> void compute(){ using boost::fusion::vector; using boost::fusion::at_c; vector<A<float>, B<float>, ...> v; at_c<from_>(v).operator()(at_c<to_>(v)); //error; needs to be const-expression. }; This question isn't about Qt, but there is a line of Qt code in my example. The setFrom() and setTo() are functions that are called based on user selection via the GUI widget. The root of my problem is that 'from' and 'to' are variables. In my compute member function I need to pick a type (A, B, etc.) based on the values of 'from' and 'to'. The only way I know how to do what I need to do is to use switch statements, but that's extremely tedious in my case and I would like to avoid. Is there anyway to convert the error line to a constant-expression?

• javascript var assignment conversion to target type

  - by pbhd

  searching for a function, which converts rhs to the type of lhs. e.g. var x=false // x is boolean now; x=assign (x, "true"); //should convert "true" to boolean and return that x=assign (x, 1); // dto, convert 1 to true x=0 // x is number x=assign (x, "123"); // should convert "123" to 123; so such a function can be written, thats not the question. But: Is there somewhere a somehow complete implementation of such a thing? I started with something like that: function assign (v, x) { if (typeof v==typeof x) { return x; } switch (typeof v) { case 'boolean' : { return x=='true'?true:false; } case 'number' : { return parseFloat(x); } } return "xxx"; } var v=true; var x='true'; var r1=assign (v, x); console.log (typeof r1+ " "+r1); v=10; x="123"; var r1=assign (v, x); console.log (typeof r1+ " "+r1); which of course is not complete, but maybe shows what I'm goig for.

• jQuery remove SELECT options based on another SELECT selected on change and on load

  - by John Sieber

  I'm using the following jQuery code to remove options from a select and it is working well. But instead of it only executing when the theOption2 select is changed I would also like it to work when the page is loaded depending on the selected item that is selected. I tried using the a copy of the script and changing the .change to .load and also tried using (window).load without the desired results. Essentially, I need the script to execute on change of the Options1 and on the loading of the page. Any help with this would be greatly appreciated. <script type="text/javascript"> $(document).ready(function() { //copy the second select, so we can easily reset it var selectClone = $('#theOptions2').clone(); $('#theOptions1').change(function() { var val = parseInt($(this).val()); //reset the second select on each change $('#theOptions2').html(selectClone.html()) switch(val) { //if 2 is selected remove C case 2 : $('#theOptions2').find('option:contains(c)').remove();break; //if 3 is selected remove A case 3 : $('#theOptions2').find('option:contains(a)').remove();break; } }); }); </script> <select id="theOptions1"> <option value="1">1</option> <option value="2" selected="selected">2</option> <option value="3">3</option> </select> <br /> <select id="theOptions2"> <option>a</option> <option>b</option> <option>c</option> </select>

• How do I deserialize a namespaced element to an object in .net?

  - by pc1oad1etter

  Given this XML snippet: ... <InSide:setHierarchyUpdates> <automaticUpdateInterval>5</automaticUpdateInterval> <shouldRunAutomaticUpdates>true<shouldRunAutomaticUpdates> </InSide:setHierarchyUpdates> ... I am attempting to serialize this object: Imports System.Xml.Serialization <XmlRoot(ElementName:="setHierarchyUpdates", namespace:="InSide")> _ Public Class HierarchyUpdate <XmlElement(ElementName:="shouldRunAutomaticUpdates")> _ Public shouldRunAutomaticUpdates As Boolean <XmlElement(ElementName:="automaticUpdateInterval")> _ Public automaticUpdateInterval As Integer End Class Like this: Dim hierarchyUpdater As New HierarchyUpdate Dim x As New XmlSerializer(hierarchyUpdater.GetType) Dim objReader As Xml.XmlNodeReader = New Xml.XmlNodeReader(myXMLNode) hierarchyUpdater = x.Deserialize(objReader) However, the object, after deserialization, has values of false and zero. If I switch the objReader to a streamreader and read this in as a file, with none of its parents and no namespaces, it works: <setHierarchyUpdates> <automaticUpdateInterval>5</automaticUpdateInterval> <shouldRunAutomaticUpdates>true<shouldRunAutomaticUpdates> </setHierarchyUpdates> What am I doing wrong? Should I use something other than XMLRoot in the class definition, because, as an XML node, it's not really the root? If so, what? Why are no errors returned when this fails?

• Why the compiler is not compiling a line in C++ Builder?

  - by MLB

  Hi boys: I was programming an application in C++ Builder 6, and I had encountered this rare problem: void RotateDice() { Graphics::TBitmap *MYbitmap = new Graphics::TBitmap(); Randomize(); int rn = random(6) + 1; switch (rn) { case 1: { //... break; } //... Some cases... } ShowDice(); //it's a function to show the dice delete MYbitmap; //the compiler don't get it!!!! } In the line "ShowDice()", the compiler jumps to the final of the RotateDice() method, it doesn't "see" the line "delete MYbitmap". When I compile the program, every compiled line shows a little blue point in its left side, but that line don't show the blue point... it's like the compiler don't "see" the line of code. What's happening with that???? Note: Some days ago, I was writing a program in Delphi and I was advice of that problematic issue. Some like that happened to me in Delphi 7... So, waht the problem with that? I am so sorry about my English. I am from Cuba.

• Callbacks on GUI Thread

  - by miguel

  We have an external data provider which, in its construtor, takes a callback thread for returning data upon. There are some issues in the system which I am suspicious are related to threading, however, in theory they cannot be, due to the fact that the callbacks should all be returned on the same thread. My question is, does code like this require thread synchronisation? class Foo { ExternalDataProvider _provider; public Foo() { // This is the c'tor for the xternal data provider, taking a callback loop as param _provider = new ExternalDataProvider(UILoop); _provider.DataArrived += ExternalProviderCallbackMethod; } public ExternalProviderCallbackMethod() { var itemArray[] = new String[4] { "item1", "item2", "item3", "item4" }; for (int i = 0; i < itemArray.Length; i++) { string s = itemArray[i]; switch(s) { case "item1": DoItem1Action(); break; case "item2": DoItem2Action(); break; default: DoDefaultAction(); break; } } } } The issue is that, very infrequently, DoItem2Action is executingwhen DoItem1Action should be exectuing. Is it at all possible threading is at fault here? In theory, as all callbacks are arriving on the same thread, they should be serialized, right? So there should be no need for thread sync here?

• Serving .docx files through Php

  - by user275074

  Hi, I'm having issues when attempting to serve a .docx file using Php. When uploading the file I detect the file mime type and upload the file using the file with the correct extension based on the mime type; e.g. below: application/msword - doc application/vnd.openxmlformats-officedocument.wordprocessingml.document - docx When attempting to serve the files for download, I do the reverse in detecting the extension and serving based on the mime type e.g. public static function fileMimeType($extention) { if(!is_null($extention)) { switch($extention) { case 'txt': return 'text/plain'; break; case 'odt': return 'application/vnd.oasis.opendocument.text'; break; case 'doc': return 'application/msword'; break; case 'docx': return 'application/vnd.openxmlformats-officedocument.wordprocessingml.document'; break; case ('jpg' || 'jpeg'): return 'image/jpeg'; break; case 'png': return 'image/png'; break; case 'pdf': return 'application/pdf'; break; default: break; } } } All files appear to download correctly and open fine but when attempting to open a docx file, Word (on multiple files) throws a error stating the file is corrupt. Any ideas would be great, thanks.

• C++ NetUserAdd() not working?

  - by Brett Powell

  I posted earlier about how to do this, and got some great replies, and have managed to get the code written based off the MSDN example. However, it does not seem to be working properly. Its printing out the ERROR_ACCESS_DENIED message, but im not sure why as I am running it as a full admin. I was initially trying to create a USER_PRIV_ADMIN, but the MSDN said it can only use USER_PRIV_USER, but sadly neither work. Im hoping someone can spot a mistake or has an idea.

• Deal with update location for click-once.

  - by Assimilater

  I'm not sure how many people here are experts with visual studios, but I'd imagine a handful (not to raise expectations but to appeal to your egos :P). I'm working primarily in visual basic for now (though I hope to switch to c# in the near future and maybe a java or web app). Basically I'm trying to create an update feature that will work similarly to how common programs such as firefox or itunes update automatically. There is supposed to be provided functionality for this in what is called click once. I carry out the following procedures and get the following errors when trying to change the update url of my program to a password-protected ftp location. Go to project properties Go to publish click updates click browse click FTP Site Under Server put: web###.opentransfer.com Under Port: 21 Under Directory put: CMSOFT Passive mode is selected (which is what filezilla tells me the server is accessed with) Anonymous User is unselected and a username and password are typed in Push Ok Under Update location it shows: ftp://web###.opentransfer.com/CMSOFT I push Ok I see a message box titled Microsoft Visual Basic 2010 Express with an x icon Publish.UpdateUrl: The string must be a fully qualified URL or UNC path, for example "http://www.microsoft.com/myapplication" or "\server\myapplication". I've tried changing the directory to "CMSOFT/PQCM.exe" and the results are the same...hope this was descriptive enough.

• C++ Dynamic object construction

  - by Rajesh Subramanian

  I have a base class, class Msg { ParseMsg() { ParseMsgData(); ParseTrailer(); } virtual void ParseMsgData() = 0; ParseTrailer(); }; and derived classes, class InitiateMsg { void ParseMsgData() { ... } }; class ReadOperationMsg { void ParseMsgData() { ... } }; class WriteOperationMsg { void ParseMsgData() { ... } }; and the scenario is below, void UsageFunction(string data) { Msg* msg = ParseHeader(data); ParseMsg } Msg* ParseHeader(string data) { Msg *msg = NULL; .... switch() { case 1: msg = new InitiateMsg(); break; case 2: msg = new ReadOperationMsg{(); break; case 3: msg = new WriteOperationMsg{(); break; .... } return msg; } based on the data ParseHeader method will decide which object has to be created, So I have implemented ParseHeader function outside the class where I am using. How can I make the ParseHeader function inside the Msg class and then use it? In C# the same is achieved by defining ParseHeader method as static with in class and use it from outside,

• asp.net gridview bind dateformat not working with update

  - by Brabbeldas

  I have a GridView with a TemplateField column which shows a DateTime from a DataSource. <Columns> <asp:CommandField ShowEditButton="True" /> <asp:TemplateField HeaderText="Start Date"> <EditItemTemplate> <asp:TextBox ID="txtDateStart" runat="server" Text='<%# Bind("dtDateStart", "{0:dd/MM/yyyy}") %>'</asp:TextBox> </EditItemTemplate> <ItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%# Bind("dtDateStart", "{0:dd/MM/yyyy}") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> </Columns> Displaying the date in the correct format works as it should. Note that the format starts with DAY followed by MONTH. When I switch to edit mode, change the date in the TextBox to '31-01-2013' and press the GridView's update-link i get an error: Cannot convert value of parameter 'dtDateStart' from 'System.String' to 'System.DateTime' The error is generated by the GridView not my own code. It happens before the UpdateMethod of my DataSource is called. When i type '01-31-2012' the data is processed correctly and the value is updated into the database. Somehow when the date is displayed it uses format dd-MM-yyyy (just as I need it to) But when it reads the new value form the TextBox it uses MM-dd-yyyy Can somebody please help me?

• How to get JTree expanded?

  - by Dzmitry Zhaleznichenka

  I have a wizard with several screens where user has to fill his/her details for further processing. At the second screen I have a radio group with three radio buttons that enable additional elements. To proceed, user has to choose one of them. When user selects third button, single-selection JTree filled in with data enables and user has to select an option from it. Then user has to press "Next" to get to next screen. The option he\she had selected is stored as a TreePath. So far so good. My problem is the following. If the user wants to come back from the following screen to the screen with a JTree, I want to provide him\her with the JTree expanded to the option that had been selected and to highlight the option. However, whatsoever I try to do for that (any combinations of expandPath, scrollPathToVisible, addSelectionPath, makeVisible) always provides me with a collapsed tree. I try to expand both leaves and nodes. My code looks like this: rbProcessJTree.setSelected(isProcessJTree()); if (null != getSelectedTablePath()){ trTables.addSelectionPath(getSelectedTablePath()); trTables.expandPath(getSelectedTablePath()); trTables.scrollPathToVisible(getSelectedTablePath()); } When setSelected() is called, state change listener is invoked that enables JTree. The model is loaded during the form initialization. Each time I switch between screens, I save the input data from previous screen and dispose it. Then, when I need to open previous screen back, I save data from the following screen, dispose it, load data to this screen and show it. So each time the screen is generating from scratch. Could you please explain, what sequence of operations has to be done to get JTree expanded in a newly created form,with data model loaded and selection path provided?

• Problems with starting an activity in onStart

  - by Fizz

  Hello everyone. I'm trying to start a floating activity from onStart to retrieve some info from the user right when the initial activity begins. I have the following: @Override public void onStart(){ super.onStart(); callProfileDialog(); } And callProfileDialog() is just: private void callProfileDialog(){ Intent i = new Intent(this, com.utility.ProfileDialog.class); startActivityForResult(i, PROFDIALOG); } ProfileDialog.class returns a String from an input box. If the result returned is RESULT_CANCELED then I restart the activity. The problem I'm having is that when the program starts, the screen is just black. If I hit the Back button a RESULT_CANCELED is returned then the initial activity shows as well as the floating activity (since it recalled itself when it got a RESULT_CANCELED). Why can't I get the activities show by calling ProfileDialog.class from onStart()? I got the same result when I called it at the end of onCreate() which is way I switch over to use onStart(). Thanks for the help.

• Is Subversion's 'Lazy Copy' still lazy when overwriting a previously deleted file?

  - by JW

  Is Subversion's 'Lazy Copy' still lazy when overwriting a previously deleted file? I store my externals in a separate folder for each version: i.e say for dojo I'd have: webroot\ scripts\ dojo-v-1.0.0\ dojo-v-1.1.0\ etc. By doing this, for me at least, I feel it makes it easier to switch over to a new version. By only adding each new version i am not really giving svn the history it needs to do lazy copies. So one tactic I have used is to svn copy over the old version over to where the new one will be then svn delete that whole folder then unpack my newer version into that place then svn add them The idea is to avoid having a massive amount of duplicated data in my repo. I hope svn is looking at the new files and saying, "hey, i already had this once, copied, then deleted...so i am only going to be lazy store the changes". That was my theory - but does that happen in practice? p.s. Yes I know an alternative is to set the 'externals properties on the folder' - but that's another question.

• Passing contextual info to Views in ASP.NET MVC

  - by Andrey

  I wonder - what is the best way to supply contextual (i.e. not related to any particular view, but to all views at the same time) info to a view (or to master page)? Consider the following scenario. Suppose we have an app that supports multiple UI languages. User can switch them via UI's widgets (something like tabs at the top of the page). Each language is rendered as a separate tab. Tab for the current language should not be rendered. To address these requirements I'm planning to have a javascript piece that will hide current's language tab on the client. To do this, I need current's language tab Id on the client. So, I need some way of passing the Id to master page (for it to be 'fused' into the js script). The best thing I can think of is that all my ViewModels should inherit some ViewModeBase that has a field to hold current language tab Id. Then, whatever View I'm rendering, this Id will always be available for the master page's hiding script. However, I'm concerned that this ViewModelBase can potentially grow in an uncontrolled fashion as number of such pieces of contextual info (like current language) will grow.. Any ideas?

• reset TextView scroll to top

  - by JayAvon

  Okay well I apologize for how sloppy this code is, but I still cant figure out how to post a code tag on here correctly. So I am making an Android application (Java) and i have a scrolling text field. If the user scrolls a long row down and stays at the end when they click the next row and if it is short, it will be scrolled down on that element too even though it may be a 1 line(and non scrollable) row. I was wondering if there is any way I can call something to right after txtLvlInfo.setText to reset the x-scroll value to 0 or something so it is always reset to the top of the content, long or short. Thanks for any help with this and please let me know if I need to clarify more. TextView txtLvlInfo = (TextView) findViewById(R.id.txtLevelInfo); txtLvlInfo.setMovementMethod(new ScrollingMovementMethod()); switch (v.getId()){ case R.id.row1: txtLvlInfo.setText("1: My text view is only two lines max and so I set it to scroll, if the user clicks row2 to load that text while having me scrolled down they have to click and pull to drag back down to the top of text view 2 row."); break; case R.id.row2: txtLvlInfo.setText("I only fill line 1 of the two."); break; android:textColor="#052027" android:text="" android:id="@+id/txtLevelInfo" android:scrollbars="vertical" android:layout_alignParentLeft="true" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_toRightOf="@+id/minimizeBtn" android:layout_marginRight="38dip"

  Hi, I have a few properties defined in my header file like so @property (assign) bool connectivity_N; @property (assign) bool isConnected_N; In my implementation file I have an init and the synthesized properties like so @implementation Map @synthesize connectivity_N; @synthesize isConnected_N; a init to set the initial values like so -(id) init { if( (self=[super init]) ) { //initialise default properties self.connectivity_N=NO; self.isConnected_N=NO; } return self; } I'm running into an error that states Error: accessing unknown 'connectivity_N' class method. In this public method within the class +(bool) isConnectable:(directions) theDirection{ bool isTheDirectionConnectable= NO; switch (theDirection) { case north: isTheDirectionConnectable= self.connectivity_N; break; I'm not sure why is this so as I'm trying to grab the value of the property. According to the apple developer documentation "The default names for the getter and setter methods associated with a property are propertyName and setPropertyName: respectively—for example, given a property “foo”, the accessors would be foo and setFoo:" That has given me a clue that I've done something wrong here, I'm fairly new to objective C so would appreciate anyone who spends the time to explain this to me. Thanks!

• Using Mercurial in a Large Organization

  - by Kristopher Johnson

  I've been using Mercurial for my own personal projects for a while, and I love it. My employer is considering a switch from CVS to SVN, but I'm wondering whether I should push for Mercurial (or some other DVCS) instead. One wrinkle with Mercurial is that it seems to be designed around the idea of having a single repository per "project". In this organization, there are dozens of different executables, DLLs, and other components in the current CVS repository, hierarchically organized. There are a lot of generic reusable components, but also some customer-specific components, and customer-specific configurations. The current build procedures generally get some set of subtrees out of the CVS repository. If we move from CVS to Mercurial, what is the best way to organize the repository/repositories? Should we have one huge Mercurial repository containing everything? If not, how fine-grained should the smaller repositories be? I think people will find it very annoying if they have to pull and push updates from a lot of different places, but they will also find it annoying if they have to pull/push the entire company codebase. Anybody have experience with this, or advice?
