• Problem in calling Excel function

  - by Newbie

  I am facing a problem while making Excel's LinEST function. My program goes like MyExcel.Application xl = new MyExcel.Application(); MyExcel.WorksheetFunction wsf = xl.WorksheetFunction; List<int> x = new List<int> { 1, 2, 3, 4 }; List<int> y = new List<int> { 11, 12, 45, 42 }; object o = wsf.LinEst(x, y, true, true); And the namespace is using MyExcel = Microsoft.Office.Interop.Excel; The program is compiling smoothly but at runtime it is throwing an error {System.Runtime.InteropServices.COMException (0x80020005): Type mismatch. (Exception from HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH)) Actually this is the first time I am using Excel function .. so I am unable to proceed further. If any one has run thru this kind of situation and has solved, please help me. I am using C# 3.0 Thanks

• jQuery Validation errorPlacement

  - by Steve

  This works: $("[id$='_zzz']").rules( "add", { required: true, minlength: 8, messages: { required: "...", minlength: jQuery.format("...") } } ); The error message comes up. When I try to style the message, this doesn't work: $("[id$='_zzz']").rules( "add", { required: true, minlength: 8, messages: { required: "...", minlength: jQuery.format("...") }, errorElement: "span", errorPlacement: function(error, element) { error.insertAfter(element); error.css("margin", "0 0 0 5px"); } } ); When I style via the validate function, the styling is applied so it works: $('#aspnetForm').validate({ errorElement: "span", errorPlacement: function(error, element) { error.insertAfter(element); error.css("margin", "0 0 0 5px"); } }); Why can't I style using errorplacement in the rules add function?

• How to strink matrix using array mask in Matlab?

  - by Pyrolistical

  This seems to be a very common problem of mine. data = [1 2 3; 4 5 6]; mask = [true false true]; mask = repmat(mask, 2, 1); data(mask) ==> [1; 4; 3; 6] What I wanted was [1 3; 4 6] Yes I can just reshape it to the right size, but that seems the wrong way to do it. Is there a better way? Why doesn't data(mask) return a matrix when it is actually rectangular? I understand in the general case it may not be, but in my case since my original mask is an array it always will be.

• MouseLeftButtonUpEvent & Bubbling in Canvas

  - by Maxim

  Hi guys, I think I'm going crazy... I have Canvas with event handlers for MouseMove & MouseLeftButtonUp. However MouseLeftButtonUp is not being fired when it happens with cursor over TextBlock that is inside canvas. (it fires just fine when I release mouse button in empty space of the canvas) I tried attaching handler via AddHandler and using regular += syntax, nothing seems to work. I tried using Canvas.CaptureMouse() but it doesnt seem to work either (CaptureMouse returns true btw). MouseLeftButtonUp just doesnt want to propagate to it's parent when it happens over TextBlock (or any other element with IsHitTestVisible = true) inside Canvas. Please help.

• How to draw a smooth/dithered gradient on a canvas in Android

  - by André

  Several answers mention to use GradientDrawable.setDither(true) to draw smooth gradients in Android. That has no effect in my code. Any idea what I have to change to get a well looking gradient in my live wallpaper? GradientDrawable gradient = new GradientDrawable(Orientation.TL_BR, colors); gradient.setGradientType(GradientDrawable.RADIAL_GRADIENT); gradient.setGradientRadius(canvas.getWidth() * 2); gradient.setDither(true);g gradient.setGradientCenter(-0.1f, -0.1f); gradient.setBounds(cb); gradient.draw(canvas);

• Master Details and collectionViewSource in separate views cannot make it work.

  - by devnet247

  Hi all, I really cannot seem to make/understand how it works with separate views It all works fine if a bundle all together in a single window. I have a list of Countries-Cities-etc... When you select a country it should load it's cities. Works So I bind 3 listboxes successfully using collection sources and no codebehind more or less (just code to set the datacontext and selectionChanged). you can download the project here http://cid-9db5ae91a2948485.skydrive.live.com/self.aspx/PublicFolder/2MasterDetails.zip <Window.Resources> <CollectionViewSource Source="{Binding}" x:Key="cvsCountryList"/> <CollectionViewSource Source="{Binding Source={StaticResource cvsCountryList},Path=Cities}" x:Key="cvsCityList"/> <CollectionViewSource Source="{Binding Source={StaticResource cvsCityList},Path=Hotels}" x:Key="cvsHotelList"/> </Window.Resources> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition/> </Grid.RowDefinitions> <TextBlock Grid.Column="0" Grid.Row="0" Text="Countries"/> <TextBlock Grid.Column="1" Grid.Row="0" Text="Cities"/> <TextBlock Grid.Column="2" Grid.Row="0" Text="Hotels"/> <ListBox Grid.Column="0" Grid.Row="1" Name="lstCountries" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding Source={StaticResource cvsCountryList}}" DisplayMemberPath="Name" SelectionChanged="OnSelectionChanged"/> <ListBox Grid.Column="1" Grid.Row="1" Name="lstCities" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding Source={StaticResource cvsCityList}}" DisplayMemberPath="Name" SelectionChanged="OnSelectionChanged"/> <ListBox Grid.Column="2" Grid.Row="1" Name="lstHotels" ItemsSource="{Binding Source={StaticResource cvsHotelList}}" DisplayMemberPath="Name" SelectionChanged="OnSelectionChanged"/> </Grid> Does not work I am trying to implement the same using a view for each eg(LeftSideMasterControl -RightSideDetailsControls) However I cannot seem to make them bind.

• Specify an inline callback function as an argument.

  - by Matthias Vance

  LS, Let me first explain what I'm trying to achieve using some pseudo-code (JavaScript). // Declare our function that takes a callback as as an argument, and calls the callback with true. B(func) { func(true); } // Call the function B(function(bool success) { /* code that uses success */ }); I hope this says it all. If not, please comment on my question so I can write a little more to clarify my issue. What I want is to have code like this in C++. I have tried to use lambda functions, but I was unable to specify a parameter type for those. Kind regards, Matthias Vance

• Link to open jQuery Accordion

  - by pioneer

  I'm trying to open an accordion div from an external link. I see the "navigation: true" option but I'm not sure how to implement it. Do you give each div an id and call the link like this? http://domain.com/link#anchorid I'm new to jQuery so bear with me. Here is the code I'm using if it helps. <script type="text/javascript"> $(function(){ $("#accordion").accordion({ header: "h2", autoHeight: false, animated: false, navigation: true }); }); </script> <div id="accordion"> <div> <h2><a href="#">Services</a></h2> <div class="services"> <p>More information about all of these services</p> </div> </div>

• How can I set partial text color in JTextArea

  - by ComputerJy

  I want to set color for specific lines in the text area. What I've found so far, was the following // Declarations private final DefaultStyledDocument document; private final MutableAttributeSet homeAttributeSet; private final MutableAttributeSet awayAttributeSet; // Usage in the form constructor jTextAreaLog.setDocument(document); homeAttributeSet = new SimpleAttributeSet(); StyleConstants.setForeground(homeAttributeSet, Color.blue); StyleConstants.setItalic(homeAttributeSet, true); awayAttributeSet = new SimpleAttributeSet(); StyleConstants.setForeground(awayAttributeSet, Color.red); // Setting the style of the last line final int start = jTextAreaLog.getLineStartOffset(jTextAreaLog.getLineCount() - 2); final int length = jTextAreaLog.getLineEndOffset(jTextAreaLog.getLineCount() - 1) - start; document.setCharacterAttributes(start, length, awayAttributeSet, true); But this is not working. What am I doing wrong?

• PHP preg_replace function returns different values with the same data set

  - by patryk

  I need to use preg_match PHP function. I have a simple pattern to check the string and the thing is as follows: when I run the script at first, it gives me no match (it is supposed to match though) but when I hold F5 in my browser for a while, out of a sudden it says there's a match within the string. As I keep pushing F5, it gives either true or false. Say the pattern is /^(.*)\/[A-Za-z0-9]*$/ (I guess it's not the best way but still) and the subject is galeria/zdjecia/. I believe preg_match should return true with this set of data. Note that the data does not change when pressing F5. Why is that?

When I go to compare ListA and ListB, should I get true? ListA.Equals(ListB)==true; //???

• Why doesn't Visual Studio show an exception message when my exception occurs in a static constructor

  - by Tim Goodman

  I'm running this C# code in Visual Studio in debug mode: public class MyHandlerFactory : IHttpHandlerFactory { private static Dictionary<string, bool> myDictionary = new Dictionary<string, bool>(); static MyHandlerFactory() { myDictionary.Add("someKey",true); myDictionary.Add("someKey",true); // fails due to duplicate key } } Outside of the static constructor, when I get to the line with the error Visual Studio highlights it and pops up a message about the exception. But in the static constructor I get no such message. I am stepping through line-by-line, so I know that I'm getting to that line and no further. Why is this? (I have no idea if that fact that my class implements IHttpHandlerFactory matters, but I included it just in case.) This is VS2005, .Net 2.0

• Are there any real benefits to including javascript dynamically rather than as script tags at the bo

  - by SB

  I've read that including the scripts dynamically may provide some better performance, however i'm not really seeing that on the small local tests I'm doing. I created a jquery plugin to dynamically load other plugins as necessary and am curious as to if this is actually a good idea. The following would be called onready or at the bottom of the page(I can provide the source for the plugin if anyone is interested): $.fn.executePlugin( 'qtip', // looks in default folder { required: '/javascript/plugin/easing.js', // not really required for qtip just testing it version: 1, //used for versioning and caching checkelement: '#thumbnail', // will not include plugin if $(element).length==0 css: 'page.css', // include this css file as well with plugin cache:true, // $.ajax will use cache:true success:function() { // success function to be called after the plugin loads - apply qtip to an element $('#thumbnail').qtip( { content: 'Some basic content for the tooltip', // Give it some content, in this case a simple string style: {name:'cream'}, }); } });

• DataBinding: ComboBox.Text not updating when SelectedValue changes?

  - by Rob

  This is the relevant designer code for the ComboBox: Me.ProbationComboBox.DataBindings.Add(New System.Windows.Forms.Binding("Enabled", Me.RegistrationBindingSource, "IsRegistered", True)) Me.ProbationComboBox.DataBindings.Add(New System.Windows.Forms.Binding("SelectedValue", Me.RegistrationBindingSource, "ProbationID", True)) Me.ProbationComboBox.DataSource = Me.ProbationBindingSource Me.ProbationComboBox.DisplayMember = "probation" Me.ProbationComboBox.ValueMember = "id" The problem is that when I call RegistrationBindingSource.ResetCurrentItem(), the SelectedValue property is refreshed with the correct value from RegistrationBindingSource.ProbationID(). However, the Text property is not updated. Until I can figure out the problem with my binding, I've been doing this as a fix: Me.ProbationComboBox.Text = CType(CType(Me.ProbationBindingSource.Current, DataRowView).Row, RootNamespace.DataSet.probationRow).probation Any ideas? Your assistance is appreciated!

• How use applicationSettings in the new web.config configuration in VS2010?

  - by citronas

  I'm used to use web deployment projects. Currently I am developing a new web application with VS2010 and want to try to get along with the new web.config principle and deployment issues. How can I replace a simple setting like <applicationSettings> <NAMESPACE> <setting name="Testenvironment" serializeAs="String"> <value>True</value> </setting> </NAMESPACE> </applicationSettings> I want to have this setting to be set to True in Debug, and false in Release. How must the entries in the Web.Debug.config and Web.Release.Config look like? And by the way: Is there some documentation about the new web.config issue? Can't seem to google for the correct keywords.

• Drupal FAPI: Add form elements on nodeform after validation

  - by ManuelBS

  Hi, I use Drupal 6.x. In my own module I alter each node form an add my own validation handler to it using $form['#validate'][] = 'my_own_validation_function'; Then I have the function function my_own_validation_function($form, &$form_state) { //if validation fails, i would like to rebuild the form to add additional form elements in hook_form_alter $form_state['rebuild'] = True; } My problem ist, that the validation functions does not respect my 'rebuild' = True becaus the form is never processed by hook_form_alter after validation. But I need hook_form_alter to add my additional form element. Is there a solution for my problem? Or are form_state changes in an own validation handler not respected even if I set &$form_state as a "pointer"? Thanks and cheers.

• PyGTK: dynamic label wrapping

  - by detly

  It's a known bug/issue that a label in GTK will not dynamically resize when the parent changes. It's one of those really annoying small details, and I want to hack around it if possible. I followed the approach at 16 software, but as per the disclaimer you cannot then resize it smaller. So I attempted a trick mentioned in one of the comments (the set_size_request call in the signal callback), but this results in some sort of infinite loop (try it and see). Does anyone have any other ideas? (You can't block the signal just for the duration of the call, since as the print statements seem to indicate, the problem starts after the function is left.) The code is below. You can see what I mean if you run it and try to resize the window larger and then smaller. (If you want to see the original problem, comment out the line after "Connect to the size-allocate signal", run it, and resize the window bigger.) The Glade file ("example.glade"): <?xml version="1.0"?> <glade-interface> <!-- interface-requires gtk+ 2.16 --> <!-- interface-naming-policy project-wide --> <widget class="GtkWindow" id="window1"> <property name="visible">True</property> <signal name="destroy" handler="on_destroy"/> <child> <widget class="GtkLabel" id="label1"> <property name="visible">True</property> <property name="label" translatable="yes">In publishing and graphic design, lorem ipsum[p][1][2] is the name given to commonly used placeholder text (filler text) to demonstrate the graphic elements of a document or visual presentation, such as font, typography, and layout. The lorem ipsum text, which is typically a nonsensical list of semi-Latin words, is a hacked version of a Latin text by Cicero, with words/letters omitted and others inserted, but not proper Latin[1][2] (see below: History and discovery). The closest English translation would be "pain itself" (dolorem = pain, grief, misery, suffering; ipsum = itself).</property> <property name="wrap">True</property> </widget> </child> </widget> </glade-interface> The Python code: #!/usr/bin/python import pygtk import gobject import gtk.glade def wrapped_label_hack(gtklabel, allocation): print "In wrapped_label_hack" gtklabel.set_size_request(allocation.width, -1) # If you uncomment this, we get INFINITE LOOPING! # gtklabel.set_size_request(-1, -1) print "Leaving wrapped_label_hack" class ExampleGTK: def __init__(self, filename): self.tree = gtk.glade.XML(filename, "window1", "Example") self.id = "window1" self.tree.signal_autoconnect(self) # Connect to the size-allocate signal self.get_widget("label1").connect("size-allocate", wrapped_label_hack) def on_destroy(self, widget): self.close() def get_widget(self, id): return self.tree.get_widget(id) def close(self): window = self.get_widget(self.id) if window is not None: window.destroy() gtk.main_quit() if __name__ == "__main__": window = ExampleGTK("example.glade") gtk.main()

• Adding an item to an existent window

  - by farhad

  Hello! How can i add an item to an existent window? I tried win.add() but it does not seem to work. Why? This is my piece of code: function combo_service(winTitle,desc,input_param) { /* parametri */ param=input_param.split(","); /* della forma: param[0]="doc1:text", quindi da splittare di nuovo */ /* cosi' non la creo più volte */ win; if (!win) var win = new Ext.Window({ //title:Ext.get('page-title').dom.innerHTML renderTo:Ext.getBody() ,iconCls:'icon-bulb' ,width:420 ,height:240 ,title:winTitle ,border:false ,layout:'fit' ,items:[{ // form as the only item in window xtype:'form' ,labelWidth:60 ,html:desc ,frame:true ,items:[{ // textfield fieldLabel:desc ,xtype:'textfield' ,anchor:'-18' }] }] }); win.add({ // form as the only item in window xtype:'form' ,labelWidth:60 ,html:desc ,frame:true ,items:[{ // textfield fieldLabel:desc ,xtype:'textfield' ,anchor:'-18' }]}); win.show(); }; What's wrong with my code? Thank you very much.

• log4net logging problem

  - by Dotnet_user

  Hello everyone, I'm not sure if this is the right forum to post this question. But I'm just hoping someone here might have used log4net in the past, so hoping to get some help. I'm using log4net to log my exceptions. The configuration settings look like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net debug="false"> <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="C:\Logs\sample.log" /> <appendToFile value="true"/> <rollingStyle value="Size"/> <maxSizeRollBackups value="10"/> <maximumFileSize value="10MB"/> <staticLogFileName value="true"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%-5level %date %logger.%method[line %line] - %message%newline"/> </layout> </appender> <root> <level value="INFO"/> <appender-ref ref="RollingLogFileAppender"/> </root> </log4net> </configuration> I started out by adding this configuration to web.config, but I got an error (VS studio could not find a schema for log4net-"Could not find schema information for the element log4net"). So I followed this link (http://stackoverflow.com/questions/174430/log4net-could-not-find-schema-information-messages) and configured my settings in a separate xml file and added the following line of code in my AssemblyInfo.cs: [assembly: log4net.Config.XmlConfigurator(ConfigFile = "xmlfile.xml", Watch = true)] And in the actual code, I placed this line: public void CreateUser(String username, String password) { try { log.Info("Inside createuser"); //code for creating user } catch(exception e) { log.Info("something happened in create user", e); } } The problem is that the log file is not being created. I can't see anything inside C:\Logs. Can anybody tell me what I'm doing wrong here? Any suggestions/inputs will be very helpful. Thank you all in advance.
