  • Graph spacing algorithm

    - by David
    Hi, I am looking for an algorithm that would be useful for determining x y coordinates for a number objects to display on screen. Each object can be related to another object and there can be any number of relationships and there can be any number of these objects. There is no restriction on the overall size of area on which to display these object. I am writing this in php and would be looking to store the coordinates in an array.

  • JQuery Tooltip Plugin from Jorn

    - by Jeff Ancel
    I am thinking someone may have run across this one, but not sure. From a high level, I am trying to roll over a input [type=text] and display a tool tip (with the contained value) using the plugin available at http://bassitance.de. I have to use titles and classes for validation on the specific elements, so I put a blank div to hold the input [type=text] value for the roll over. Issue: It won't hold the value of 2 text boxes at once. Once I put a value in the box on the right, the tooltip on the left goes away. Same thing if I switch it aroun. I can't keep a tooltip on more than one element. Here is the code (Note: You will have to download the plugins in the source as I am not sure where the live versions are if there are any). <link rel="stylesheet" href="/scripts/jquery-tooltip/jquery.tooltip.css" /> <script type="text/javascript" src="/scripts/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="/scripts/jquery-tooltip/jquery.tooltip.min.js"></script> <script type="text/javascript"> $(function(){ $("input").change(function(){ var newTitle = $(this).val(); $(this).parent().attr("title",newTitle); // re-init tool tip reload(); }); // Init tooltip reload(); }); reload = function(){ $("div").tooltip(); } </script> <body> <table border="1px solid black"> <tr> <td title="hello"> <div> <input type="text" value=""/> </div> </td> <td> <div> <input type="text" value=""/> </div> </td> </tr> </table> <div id="debug"></div> </body> </html>

  • Passing array by ref.

    - by atch
    Ref. to my last post and sellibitze's comment to that post on passing array by ref rather than by value, why is it that when I'm passing array by value compiler can deduce arguments but it won't do it if I pass it by value? @Paul So just to make it clear when I'm declaring fnc: void f(int a[]);//I'm passing a pointer but when I'm declaring: void f(int &a[]);//I'm passing a ref? Do I understand this correctly now?

  • Is it fair for us to conclude XOR string encryption is less secure than well known encryption (Say Blowfish)

    - by Yan Cheng CHEOK
    I was wondering, is it fair to conclude, XOR string encryption is less secure than other encryption method, say Blowfish This is because for both methods, their input are Unencrypted string A secret key string XOR(string value,string key) { string retval(value); short unsigned int klen=key.length(); short unsigned int vlen=value.length(); short unsigned int k=0; short unsigned int v=0; for(v;v<vlen;v++) { retval[v]=value[v]^key[k]; k=(++k<klen?k:0); } return retval; } Is there any proof that XOR encryption method is more easy to be "broken" than Blowfish if the same key is being chosen?

  • mvvm - prismv2 - INotifyPropertyChanged

    - by depictureboy
    Since this is so long and prolapsed and really doesnt ask a coherent question: 1: what is the proper way to implement subproperties of a primary object in a viewmodel? 2: Has anyone found a way to fix the delegatecommand.RaiseCanExecuteChanged issue? or do I need to fix it myself until MS does? For the rest of the story...continue on. In my viewmodel i have a doctor object property that is tied to my Model.Doctor, which is an EF POCO object. I have onPropertyChanged("Doctor") in the setter as such: Private Property Doctor() As Model.Doctor Get Return _objDoctor End Get Set(ByVal Value As Model.Doctor) _objDoctor = Value OnPropertyChanged("Doctor") End Set End Property The only time OnPropertyChanged fires if the WHOLE object changes. This wouldnt be a problem except that I need to know when the properties of doctor changes, so that I can enable other controls on my form(save button for example). I have tried to implement it in this way: Public Property FirstName() As String Get Return _objDoctor.FirstName End Get Set(ByVal Value As String) _objDoctor.FirstName = Value OnPropertyChanged("Doctor") End Set End Property this is taken from the XAMLPowerToys controls from Karl Shifflet, so i have to assume that its correct. But for the life of me I cant get it to work. I have included PRISM in here because I am using a unity container to instantiate my view and it IS a singleton. I am getting change notification to the viewmodel via eventaggregator that then populates Doctor with the new value. The reason I am doing all this is because of PRISM's DelegateCommand. So maybe that is my real issue. It appears that there is a bug in DelegateCommand that does not fire the RaiseCanExecuteChanged method on the commands that implement it and therefore needs to be fired manually. I have the code for that in my onPropertyChangedEventHandler. Of course this isnt implemented through the ICommand interface either so I have to break and make my properties DelegateCommand(of X) so that I have access to RaiseCanExecuteChanged of each command.

  • Reading multiple instances of a tag or element using XSLT

    - by shashank saket
    My RDF xml file is something like this.. <rdf:RDF> <rdf:Description rdf:about="........"> <j.0:property rdf:resource="....."/> <j.0:property rdf:resource=....."/> <j.0:property rdf:resource="........"/> </rdf:Description> </rdf:RDF> Now in my XSLT stylesheet I need to retrieve the values of all the j.0:property tags.

The value being the value of the first property encountered. Kindly help as to how I can get the value for each property.

  • WPF designer gives exception when databinding a label to a checkbox

    - by John
    I'm sure it's something stupid, but I'm playing around with databinding. I have a checkbox and a label on a form. What I'm trying to do is simply bind the Content of the label to the checkbox's IsChecked value. What I've done runs fine (no compilation errors and acts as expected), but if I touch the label in the XAML, the designer trows an exception: System.NullReferenceException Object reference not set to an instance of an object. at MS.Internal.Designer.PropertyEditing.Editors.MarkupExtensionInlineEditorControl.BuildBindingString(Boolean modeSupported, PropertyEntry propertyEntry) at <Window x:Class="UnitTestHelper.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:FileSysCtls="clr-namespace:WPFFileSystemUserControls;assembly=WPFFileSystemUserControls" xmlns:HelperClasses="clr-namespace:UnitTestHelper" Title="MainWindow" Height="406" Width="531"> <Window.Resources> <HelperClasses:ThreestateToBinary x:Key="CheckConverter" /> </Window.Resources> <Grid Height="367" Width="509"> <CheckBox Content="Step into subfolders" Height="16" HorizontalAlignment="Left" Margin="17,254,0,0" Name="chkSubfolders" VerticalAlignment="Top" Width="130" IsThreeState="False" /> <Label Height="28" HorizontalAlignment="Left" Margin="376,254,0,0" Name="lblStepResult" VerticalAlignment="Top" Width="120" IsEnabled="True" Content="{Binding IsChecked, ElementName=chkSubfolders, Mode=OneWay, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource CheckConverter}}" /> </Grid> The ThreeStateToBinary class is as follows: class ThreestateToBinary : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if ((bool)value) return "Checked"; else return "Not checked"; //throw new NotImplementedException(); } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { return ((string)value == "Checked"); //throw new NotImplementedException(); } #endregion } Quite honestly, I'm playing around with it at this point. It was originally simpler (not using the ValueConverter) but was displaying similar behavior when I simply had the content set to: Content="{Binding IsChecked, ElementName=chkSubfolders, UpdateSourceTrigger=PropertyChanged}" Any ideas? Thanks, John

  • Jquery: Datalink - Data linking

    - by Pickels
    I was trying out the Jquery Data linking proposal from Microsoft and noticed something strange. My objects get this extra property and I was wondering what the reason for that is. I first thought it was a mistake I made but I noticed their demo page does the same thing This is the json result of my objects: [{ "propertyName":"ProductNamese", "controlType":"Text", "jQuery1274021322131":6 }, { "propertyName":"Price", "controlType":"Number", "jQuery1274021322131":9 }, { "propertyName":"Description", "controlType":"TextArea", "jQuery1274021322131":12 } ] The property I am talking about is "jQuery1274021322131".

  • Sharepoint listsService.updateList method clarification

    - by cyrix86
    I've seen an example here: msdn but it's a little confusing. So if I have a list definition with a field called "CustomField" and I want to update the "ShowField" attribute of this field to be true then I would do this: XmlNode listNode = listService.GetList("MyList"); string version = listNode.Attributes["Version"].Value; string guid = listNode.Attributes["Name"].Value; XmlDocument xmlDoc = new XmlDocument(); XmlElement updateFields = xmlDoc.CreateElement("Fields"); string fieldXml = @"<Method ID="1"><Field Name="CustomField" ShowField="true" /></Method>"; updateFields.InnerXml = fieldXml; XmlNode result = listService.UpdateList(guid, null, null, updateFields, null, version); I'm confused because it would seem that you would need to provide a field element to indicate what field to update and then a value element to specify the new value. Could someone clarify this please?

  • jQuery Set Selected Option Using Next

    - by Dodinas
    Hello, How can I, using jQuery, set the "next" item of an already selected item as "selected." For example, if I have: <select> <option value="1" >Number 1</option> <option value="2" selected="selected">Number 2</option> <option value="3" >Number 3</option> <option value="4" >Number 4</option> </select> We can see that "Number 2" is selected, and using jQuery, I'd like to set "Number 3" as selected, and remove the selected "attribute" from "Number 2". I'm assuming I need to use the next selector, but I'm not quite sure how to implement. Any ideas? Thanks!

    I have an ObservableCollection bound to a list box and a boolean property bound to a button. I then defined two converters, one that operates on the collection and the other operates on the boolean property.

The user can then select an object from the first list, click an button which moves it to the 'selected' list. Then when the form is saved the objects in the selected list are saved in the manytomany field. Thanks

  • Whats the KeyCode for overwriting a text in TextBox in winforms

    - by Ragha J
    I have a custom control which extends from TextBox. In the KeyDown event of the control I have access to the KeyCode property of keyEventArgs If the text in the textbox is selected and some other text is typed on top of it, the keyCodes that I am getting in the KeyDown event are different each time and in the KeyPress event I get the actual value. For ex: If the textbox has value 1234 and now I select 1234 and type 5 on top of it, I want to to be able to know in any of the events by some key combination that the old value 1234 is gone and the new value of the textbox is 5.

  • Success function not being called when form is submitted. jQuery / validationEngine / PHP form proce

    Hi, I've been trying to figure out why the following script's success function isn't running.

  • Is it possible to create a generic Util Function to be used in Eval Page

    - by Nassign
    I am currently binding a Nullable bit column to a listview control. When you declare a list view item I need to handle the case when the null value is used instead of just true or false. <asp:Checkbox ID="Chk1" runat="server" Checked='<%# HandleNullableBool(Eval("IsUsed")) %>' /> Then in the page I add a HandleNullableBool() function inside the ASPX page. protected static bool HandleNullableBool(object value) { return (value == null) ? false : (bool)value; } This works fine but I need to use this in several pages so I tried creating a utility class with a static HandleNullableBool. But using it in the asp page does not work. Is there a way to do this in another class instead of the ASPX page? <asp:Checkbox ID="Chk1" runat="server" Checked='<%# Util.HandleNullableBool(Eval("IsUsed")) %>' />

  • Loops inside loops

    - by cozzy
    Hi, I'd like to find easier way to write loops inside loops. Here is example code of 3 levels of 'for' loops: int level = 0; int value = 0; bool next = false; for (int i0 = 0; i0 < 6; i0++) { level = 0; value = i0; method(); if (next) for (int i1 = 0; i1 < 6; i1++) { level = 1; value = i1; method(); if (next) for (int i2 = 0; i2 < 6; i2++) { level = 2; value = i2; method(); if (next) { //Do somethnig } } } } private void method() { //use int 'level' and 'value' //determine bool 'next' } I wonder if it's possible to write the same thing different way. To set number of levels(number of loops) and loop repeats. In this case levels = 3; repeats = 6;. I need it because I am using more than 20 loops inside themselves and than the code is not comprehensible. I hope my explanation was ok and thanks for help.

  • Eclipselink read complex object model in an ordered way

    - by Raven
    Hi, I need to read a complex model in an ordered way with eclipselink. The order is mandantory because it is a huge database and I want to have an output of a small portion of the database in a jface tableview. Trying to reorder it in the loading/quering thread takes too long and ordering it in the LabelProvider blocks the UI thread too much time, so I thought if Eclipselink could be used that way, that the database will order it, it might give me the performance I need. Unfortunately the object model can not be changed :-( The model is something like: @SuppressWarnings("serial") @Entity public class Thing implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; @OneToMany(cascade=CascadeType.ALL) @PrivateOwned private List<Property> properties = new ArrayList<Property>(); ... // getter and setter following here } public class Property implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; @OneToOne private Item item; private String value; ... // getter and setter following here } public class Item implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; .... // getter and setter following here } // Code end In the table view the y-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Thing m ORDER BY m.name ASC"); using the "name" attribute from the Thing objects as label. In the table view the x-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Item m ORDER BY m.name ASC"); using the "name" attribute from the Item objects as label. Each cell has the value Things.getProperties().get[x].getValue() Unfortunately the list "properties" is not ordered, so the combination of cell value and x-axis column number (x) is not necessarily correct. Therefore I need to order the list "properties" in the same way as I ordered the labeling of the x-axis. And exactly this is the thing I dont know how it is done. So querying for the Thing objects should return the list "properties" "ORDER BY name ASC" but of the "Item"s objects. My ideas are something like having a query with two JOINs. Joing Things with Property and with Item but somehow I was unable to get it to work yet. Thank you for your help and your ideas to solve this riddle.

The plugin i'm currently stuck on is for monitoring bandwidth usage, and is as follows: /etc/munin/plugins/bandwidth2 #!/bin/sh if [ "$1" = "config" ]; then echo 'graph_title Bandwidth Usage 2' echo 'graph_vlabel Bandwidth' echo 'graph_scale no' echo 'graph_category network' echo 'graph_info Bandwidth usage.' echo 'used.label Used' echo 'used.info Bandwidth used so far this month.' echo 'used.type DERIVE' echo 'used.min 0' echo 'remain.label Remaining' echo 'remain.info Bandwidth remaining this month.' echo 'remain.type DERIVE' echo 'remain.min 0' exit 0 fi cat /var/log/zen.log The contents of /var/log/zen.log are: used.value 61.3251953125 remain.value 20.0146484375 And the resulting database is: <!-- Round Robin Database Dump --><rrd> <version> 0003 </version> <step> 300 </step> <!-- Seconds --> <lastupdate> 1269936605 </lastupdate> <!-- 2010-03-30 09:10:05 BST --> <ds> <name> 42 </name> <type> DERIVE </type> <minimal_heartbeat> 600 </minimal_heartbeat> <min> 0.0000000000e+00 </min> <max> NaN </max> <!-- PDP Status --> <last_ds> 61.3251953125 </last_ds> <value> NaN </value> <unknown_sec> 5 </unknown_sec> </ds> <!-- Round Robin Archives --> <rra> <cf> AVERAGE </cf> <pdp_per_row> 1 </pdp_per_row> <!-- 300 seconds --> <params> <xff> 5.0000000000e-01 </xff> </params> <cdp_prep> <ds> <primary_value> NaN </primary_value> <secondary_value> NaN </secondary_value> <value> NaN </value> <unknown_datapoints> 0 </unknown_datapoints> </ds> </cdp_prep> <database> <!-- 2010-03-28 09:15:00 BST / 1269764100 --> <row><v> NaN </v></row> <!-- 2010-03-28 09:20:00 BST / 1269764400 --> <row><v> NaN </v></row> <!-- 2010-03-28 09:25:00 BST / 1269764700 --> <row><v> NaN </v></row> <snip> The value for last_ds is correct, it just doesn't seem to make it into the actual database. If I change DERIVE to GAUGE, it works as expected. munin-run bandwidth2 outputs the contents of /var/log/zen.log I've been all over the (sparse) docs for munin plugins, and can't find my mistake. Modifying an existing plugin didn't work for me either.

  • My Windows Service crashes with "the key does not exist in the appSettings configuration section"

    - by Greg
    There is the same question listed under http://stackoverflow.com/questions/427007/the-key-userid-does-not-exist-in-the-appsettings-configuration-section, but unfortunately none of the answers worked in my case. All was working fine, I checked everything in and when I opened the solution again, it started crashing on the above. I cannot find any hint of what I am doing wrong. Any ideas? <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="URI" value="http://123.123.123.123:8080/smsxml/collector" /> <add key="Provider" value="123" /> <add key="LongCode" value="+123" /> <add key="PassWord" value="123" /> </appSettings> </configuration>

  • Binary Tree in C Insertion Error

    - by Paul
    I'm quite new to C and I'm trying to implement a Binary Tree in C which will store a number and a string and then print them off e.g. 1 : Bread 2 : WashingUpLiquid etc. The code I have so far is: #include <stdio.h> #include <stdlib.h> #define LENGTH 300 struct node { int data; char * definition; struct node *left; struct node *right; }; struct node *node_insert(struct node *p, int value, char * word); void print_preorder(struct node *p); int main(void) { int i = 0; int d = 0; char def[LENGTH]; struct node *root = NULL; for(i = 0; i < 2; i++) { printf("Please enter a number: \n"); scanf("%d", &d); printf("Please enter a definition for this word:\n"); scanf("%s", def); root = node_insert(root, d, def); printf("%s\n", def); } printf("preorder : "); print_preorder(root); printf("\n"); return 0; } struct node *node_insert(struct node *p, int value, char * word) { struct node *tmp_one = NULL; struct node *tmp_two = NULL; if(p == NULL) { p = (struct node *)malloc(sizeof(struct node)); p->data = value; p->definition = word; p->left = p->right = NULL; } else { tmp_one = p; while(tmp_one != NULL) { tmp_two = tmp_one; if(tmp_one->data > value) tmp_one = tmp_one->left; else tmp_one = tmp_one->right; } if(tmp_two->data > value) { tmp_two->left = (struct node *)malloc(sizeof(struct node)); tmp_two = tmp_two->left; tmp_two->data = value; tmp_two->definition = word; tmp_two->left = tmp_two->right = NULL; } else { tmp_two->right = (struct node *)malloc(sizeof(struct node)); tmp_two = tmp_two->right; tmp_two->data = value; tmp_two->definition = word; tmp_two->left = tmp_two->right = NULL; } } return(p); } void print_preorder(struct node *p) { if(p != NULL) { printf("%d : %s\n", p->data, p->definition); print_preorder(p->left); print_preorder(p->right); } } At the moment it seems to work for the ints but the description part only prints out for the last one entered. I assume it has something to do with pointers on the char array but I had no luck getting it to work. Any ideas or advice? Thanks
