  • Best practice for setting Effect parameters in XNA

    - by hichaeretaqua
    I want to ask if there is a best practice for setting Effect parameters in XNA. Or in other words, what exactly happens when I call pass.Apply(). I can imagine multiple scenarios: Each time Apply is called, all effect parameters are transferred to the GPU and therefor it has no real influence how often I set a parameter. Each time Apply is called, only the parameters that got reset are transferred. So caching Set-operations that don't actually set a new value should be avoided. Each time Apply is called, only the parameters that got changed are transferred. So caching Set-operations is useless. This whole questions is bootless because no one of the mentions ways has any noteworthy impact on game performance. So the final question: Is it useful to implement some caching of set operation like: private Matrix _world; public Matrix World { get{ return _world; } set { if (value == world) return; _effect.Parameters["xWorld"].SetValue(value); _world = value; } } Thanking you in anticipation.

  • How to run the pixel shader effcet??

    - by Yashwinder
    Below stated is the code for my pixel shader which I am rendering after the vertex shader. I have set the wordViewProjection matrix in my program but I don't know to set the progress variable i.e in my pixel shader file which will make the image displayed by the help of a quad to give out transition effect. Here is the code for my pixel shader program::: As my pixel shader is giving a static effect and now I want to use it to give some effect. So for this I have to add a progress variable in my pixel shader and initialize to the Constant table function i.e constantTable.SetValue(D3DDevice,"progress",progress ); I am having the problem in using this function for progress in my program. Anybody know how to set this variable in my program. And my new pixel Shader code is float progress : register(C0); sampler2D implicitInput : register(s0); sampler2D oldInput : register(s1); struct VS_OUTPUT { float4 Position : POSITION; float4 Color : COLOR0; float2 UV : TEXCOORD 0; }; float4 Blinds(float2 uv) { if(frac(uv.y * 5) < progress) { return tex2D(implicitInput, uv); } else { return tex2D(oldInput, uv); } } // Pixel Shader { return Blinds(input.UV); }

  • Applying effects to an existing program that uses BasicEffect

    - by Fibericon
    Using the finished product from the tutorial here. Is it possible to apply the grayscale effect from here: Making entire scene fade to grayscale Or would you basically have to rewrite everything? EDIT: It's doing something now, but the whole grayscale seems extremely blue. It's like I'm looking at it through dark blue sunglasses. Here's my draw function: protected override void Draw(GameTime gameTime) { device.SetRenderTarget(renderTarget); graphics.GraphicsDevice.Clear(Color.CornflowerBlue); //Drawing models, bullets, etc. device.SetRenderTarget(null); spriteBatch.Begin(0, BlendState.Additive, SamplerState.PointWrap, DepthStencilState.Default, RasterizerState.CullNone, grayScale); Texture2D temp = (Texture2D)renderTarget; grayScale.Parameters["coloredTexture"].SetValue(temp); grayScale.CurrentTechnique = grayScale.Techniques["Grayscale"]; foreach (EffectPass pass in grayScale.CurrentTechnique.Passes) { pass.Apply(); } spriteBatch.Draw(temp, new Vector2(GraphicsDevice.PresentationParameters.BackBufferWidth/2, GraphicsDevice.PresentationParameters.BackBufferHeight/2), null, Color.White, 0f, new Vector2(renderTarget.Width/2, renderTarget.Height/2), 1.0f, SpriteEffects.None, 0f); spriteBatch.End(); base.Draw(gameTime); } Another edit: figured out what I was doing wrong. I have Blendstate.Additive in the spriteBatch.Draw() call. It should be Blendstate.Opaque, or it literally tries to add the blank blue image to the grayscale image.

  • Pixel Shader Issues :

    - by Morphex
    I have issues with a pixel shader, my issue is mostly that I get nothing draw on the screen. float4x4 MVP; // TODO: add effect parameters here. struct VertexShaderInput { float4 Position : POSITION; float4 normal : NORMAL; float2 TEXCOORD : TEXCOORD; }; struct VertexShaderOutput { float4 Position : POSITION; }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { input.Position.w = 0; VertexShaderOutput output; output.Position = mul(input.Position, MVP); // TODO: add your vertex shader code here. return output; } float4 PixelShaderFunction(VertexShaderOutput input) : SV_TARGET { return float4(1, 0, 0, 1); } technique { pass { Profile = 11.0; VertexShader = VertexShaderFunction; PixelShader = PixelShaderFunction; } } My matrix is calculated like this : Matrix MVP = Matrix.Multiply(Matrix.Multiply(Matrix.Identity, Matrix.LookAtLH(new Vector3(-10, 10, -10), new Vector3(0), new Vector3(0, 1, -0))), Camera.Projection); VoxelEffect.Parameters["MVP"].SetValue(MVP); Visual Studio Graphics Debug shows me that my vertex shader is actually working, but not the PixelShader. I striped the Shader to the bare minimums so that I was sure the shader was correct. But why is my screen still black?

  • preventing changes to a cell in google spreadsheet [migrated]

    - by A B
    I want to prevent changes to column K in google spreadsheet. Whatever value is there, I do not want it changed. I do not like the protection feature as it makes what I consider an ugly display. My code. Unfortunately, it does absolutely nothing. The intent was to take whatever the current value is in the cell, save it, and then write it back on exit of the cell instead of saving whatever changes might have been made to the cell. The cell will either be blank to start, or will already have been modified to contain a date & time. Whatever the current contents blank or not, it should retain the same value after leaving the cell. function onEdit() { var s = SpreadsheetApp.getActiveSheet(); var r = s.getActiveCell(); var columnNum=r.getColumn() // if column is K then prevent any changes if (columnNum == 11) { var dateCell = s.getRange(r.getRow(), 11); var v=dateCell.getValue(); dateCell.setValue(v); } };

  • Silverlight 3.0 Custom Cursor in Chart

    - by Wonko the Sane
    Hello All, I'm probably overlooking something that will be obvious when I see the solution, but for now... I am attempting to use a custom cursor inside the chart area of a Toolkit chart. I have created a ControlTemplate for the chart, and a grid to contain the cursors. I show/hide the cursors, and attempt to move the containing Grid, using various Mouse events. The cursor is being displayed at the correct times, but I cannot get it to move to the correct position. Here is the ControlTemplate (the funky colors are just attempts to confirm what the different pieces of the template pertain to): <dataVisTK:Title Content="{TemplateBinding Title}" Style="{TemplateBinding TitleStyle}"/> <Grid Grid.Row="1"> <!-- Remove the Legend --> <!--<dataVisTK:Legend x:Name="Legend" Title="{TemplateBinding LegendTitle}" Style="{TemplateBinding LegendStyle}" Grid.Column="1"/>--> <chartingPrimitivesTK:EdgePanel x:Name="ChartArea" Background="#EDAEAE" Style="{TemplateBinding ChartAreaStyle}" Grid.Column="0"> <Grid Canvas.ZIndex="-1" Background="#2008AE" Style="{TemplateBinding PlotAreaStyle}"> </Grid> <Border Canvas.ZIndex="1" BorderBrush="#FF250010" BorderThickness="3" /> <Grid x:Name="gridHandCursors" Canvas.ZIndex="5" Width="32" Height="32" Visibility="Collapsed"> <Image x:Name="cursorGrab" Width="32" Source="Resources/grab.png" /> <Image x:Name="cursorGrabbing" Width="32" Source="Resources/grabbing.png" Visibility="Collapsed"/> </Grid> </chartingPrimitivesTK:EdgePanel> </Grid> </Grid> </Border> and here are the mouse events (in particular, the MouseMove): void TimelineChart_Loaded(object sender, RoutedEventArgs e) { chartTimeline.UpdateLayout(); List<FrameworkElement> chartChildren = GetLogicalChildrenBreadthFirst(chartTimeline).ToList(); mChartArea = chartChildren.Where(element => element.Name.Equals("ChartArea")).FirstOrDefault() as Panel; if (mChartArea != null) { grabCursor = chartChildren.Where(element => element.Name.Equals("cursorGrab")).FirstOrDefault() as Image; grabbingCursor = chartChildren.Where(element => element.Name.Equals("cursorGrabbing")).FirstOrDefault() as Image; mGridHandCursors = chartChildren.Where(element => element.Name.Equals("gridHandCursors")).FirstOrDefault() as Grid; mChartArea.Cursor = Cursors.None; mChartArea.MouseMove += new MouseEventHandler(mChartArea_MouseMove); mChartArea.MouseLeftButtonDown += new MouseButtonEventHandler(mChartArea_MouseLeftButtonDown); mChartArea.MouseLeftButtonUp += new MouseButtonEventHandler(mChartArea_MouseLeftButtonUp); if (mGridHandCursors != null) { mChartArea.MouseEnter += (s, e2) => mGridHandCursors.Visibility = Visibility.Visible; mChartArea.MouseLeave += (s, e2) => mGridHandCursors.Visibility = Visibility.Collapsed; } } } void mChartArea_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { if (grabCursor != null) grabCursor.Visibility = Visibility.Visible; if (grabbingCursor != null) grabbingCursor.Visibility = Visibility.Collapsed; } void mChartArea_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { if (grabCursor != null) grabCursor.Visibility = Visibility.Collapsed; if (grabbingCursor != null) grabbingCursor.Visibility = Visibility.Visible; } void mChartArea_MouseMove(object sender, MouseEventArgs e) { if (mGridHandCursors != null) { Point pt = e.GetPosition(null); mGridHandCursors.SetValue(Canvas.LeftProperty, pt.X); mGridHandCursors.SetValue(Canvas.TopProperty, pt.Y); } } Any help past this roadblock would be greatly appreciated!

  • ZendX_JQuery dialogContainer usage

    - by Kalle Johansson
    Hi ! I'm aming to make use of the ZendX_JQuery dialogContainer view helper, in order to produce a modal window, were users can input specified information(for example send a message). I'm trying to use the dialogContainer view helper in this fashion. First of, include the ZendX library in the applications library folder. Secondly, include the following row in the initViewHelper method within the Bootstrap.php file "$view-addHelperPath('ZendX/JQuery/View/Helper/', 'ZendX_JQuery_View_Helper');" third, adding the following conditional enabling of js in the layout.phtml "<?php if($this->jQuery()->isEnabled()){ $this->jQuery()->setLocalPath($this->baseUrl() .'/js/jquery/js/jquery-1.4.2.min.js') ->setUiLocalPath($this->baseUrl() .'/js/jquery/js/jquery-ui-1.8.custom.min.js') ->addStylesheet($this->baseUrl() .'/js/jquery/css/ui-lightness/jquery-ui-1.8.custom.css'); echo $this->jQuery(); } ?>" fourth, creating my Application_Form_JQueryForm extending ZendX_JQuery_Form "<?php class Application_Form_JQueryForm extends ZendX_JQuery_Form { private $form; public function init() { $this->form = $this->setAction(Zend_Controller_Front::getInstance()->getBaseUrl() . '/index/index') ->setMethod('post'); $this->form->setDecorators(array( 'FormElements', 'Form', array ('DialogContainer', array( 'id' => 'tabContainer', 'style' => 'width: 600px;', 'title' => 'Send a private message to Kalle', 'JQueryParams' => array( 'tabPosition' => 'top', ), )), )); $topic = new Zend_Form_Element_Text('topic'); $topic->setValue('topic') ->setRequired(true) ->setValidators(array('validators' => array( 'validator' => 'StringLength', 'options' => array(1,15) ))) ->setDecorators(array( 'ViewHelper', 'Description', 'Errors', array('HtmlTag', array('tag' => 'dl')))); $textarea = new Zend_Form_Element_Textarea('textarea'); $textarea->setValue('post a comment') ->setAttribs(array( 'rows' => 4, 'cols' => 20 )) ->setRequired(true) ->setValidators(array('validators' => array( 'validator' => 'StringLength', 'options' => array(1,15) ))) ->setDecorators(array( 'ViewHelper', 'Description', 'Errors', array('HtmlTag', array('tag' => 'dl')))); $submit = new Zend_Form_Element_Submit('submit'); $submit->setLabel('Send your comment') ->setDecorators(array( 'ViewHelper', 'Description', 'Errors', array('Description', array('escape' => false, 'tag' => 'span')), array('HtmlTag', array('tag' => 'dl')))) ->setDescription('or <a href="/index/index/send/false">Cancel</a>'); $this->form->addElements(array($topic, $textarea, $submit)); } }" This form is then instanciated in the controllers action method, and called in the view. And so to the problem of mine, no matter what i try, in order to for instance set, the width of the dialogContainer or any other parameter (color, css, height, so on and so forth), this being in the JQueryForm's setDecorator part for the form, i can't seem to get any change whatsoever in the resulting modal when called in the view, any help in the proper direction would be greatly appreciated Thanks in advance, Kalle Johansson

  • My Dijit DateTimeCombo widget doesn't send selected value on form submission

    - by david bessire
    i need to create a Dojo widget that lets users specify date & time. i found a sample implementation attached to an entry in the Dojo bug tracker. It looks nice and mostly works, but when i submit the form, the value sent by the client is not the user-selected value but the value sent from the server. What changes do i need to make to get the widget to submit the date & time value? Sample usage is to render a JSP with basic HTML tags (form & input), then dojo.addOnLoad a function which selects the basic elements by ID, adds dojoType attribute, and dojo.parser.parse()-es the page. Thanks in advance. The widget is implemented in two files. The application uses Dojo 1.3. File 1: DateTimeCombo.js dojo.provide("dojox.form.DateTimeCombo"); dojo.require("dojox.form._DateTimeCombo"); dojo.require("dijit.form._DateTimeTextBox"); dojo.declare( "dojox.form.DateTimeCombo", dijit.form._DateTimeTextBox, { baseClass: "dojoxformDateTimeCombo dijitTextBox", popupClass: "dojox.form._DateTimeCombo", pickerPostOpen: "pickerPostOpen_fn", _selector: 'date', constructor: function (argv) {}, postMixInProperties: function() { dojo.mixin(this.constraints, { /* datePattern: 'MM/dd/yyyy HH:mm:ss', timePattern: 'HH:mm:ss', */ datePattern: 'MM/dd/yyyy HH:mm', timePattern: 'HH:mm', clickableIncrement:'T00:15:00', visibleIncrement:'T00:15:00', visibleRange:'T01:00:00' }); this.inherited(arguments); }, _open: function () { this.inherited(arguments); if (this._picker!==null && (this.pickerPostOpen!==null && this.pickerPostOpen!=="")) { if (this._picker.pickerPostOpen_fn!==null) { this._picker.pickerPostOpen_fn(this); } } } } ); File 2: _DateTimeCombo.js dojo.provide("dojox.form._DateTimeCombo"); dojo.require("dojo.date.stamp"); dojo.require("dijit._Widget"); dojo.require("dijit._Templated"); dojo.require("dijit._Calendar"); dojo.require("dijit.form.TimeTextBox"); dojo.require("dijit.form.Button"); dojo.declare("dojox.form._DateTimeCombo", [dijit._Widget, dijit._Templated], { // invoked only if time picker is empty defaultTime: function () { var res= new Date(); res.setHours(0,0,0); return res; }, // id of this table below is the same as this.id templateString: " <table class=\"dojoxDateTimeCombo\" waiRole=\"presentation\">\ <tr class=\"dojoxTDComboCalendarContainer\">\ <td>\ <center><input dojoAttachPoint=\"calendar\" dojoType=\"dijit._Calendar\"></input></center>\ </td>\ </tr>\ <tr class=\"dojoxTDComboTimeTextBoxContainer\">\ <td>\ <center><input dojoAttachPoint=\"timePicker\" dojoType=\"dijit.form.TimeTextBox\"></input></center>\ </td>\ </tr>\ <tr><td><center><button dojoAttachPoint=\"ctButton\" dojoType=\"dijit.form.Button\">Ok</button></center></td></tr>\ </table>\ ", widgetsInTemplate: true, constructor: function(arg) {}, postMixInProperties: function() { this.inherited(arguments); }, postCreate: function() { this.inherited(arguments); this.connect(this.ctButton, "onClick", "_onValueSelected"); }, // initialize pickers to calendar value pickerPostOpen_fn: function (parent_inst) { var parent_value = parent_inst.attr('value'); if (parent_value !== null) { this.setValue(parent_value); } }, // expects a valid date object setValue: function(value) { if (value!==null) { this.calendar.attr('value', value); this.timePicker.attr('value', value); } }, // return a Date constructed date in calendar & time in time picker. getValue: function() { var value = this.calendar.attr('value'); var result=value; if (this.timePicker.value !== null) { if ((this.timePicker.value instanceof Date) === true) { result.setHours(this.timePicker.value.getHours(), this.timePicker.value.getMinutes(), this.timePicker.value.getSeconds()); return result; } } else { var defTime=this.defaultTime(); result.setHours(defTime.getHours(), defTime.getMinutes(), defTime.getSeconds()); return result; } }, _onValueSelected: function() { var value = this.getValue(); this.onValueSelected(value); }, onValueSelected: function(value) {} });

  • Trouble displaying an object in WPF

    - by Scott
    I'm so new to this that I can't even phrase the question right... Anyway, I'm trying to do something very simple and have been unable to figure it out. I have the following class: public class Day : Control, INotifyPropertyChanged { public static readonly DependencyProperty DateProperty = DependencyProperty.Register("Date", typeof(int), typeof(Day)); public int Date { get { return (int)GetValue(DateProperty); } set { SetValue(DateProperty, value); if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs("Date")); } } } public static readonly DependencyProperty DayNameProperty = DependencyProperty.Register("DayName", typeof(String), typeof(Day)); public String DayName { get { return (String)GetValue(DayNameProperty); } set { SetValue(DayNameProperty, value); if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs("DayName")); } } } static Day() { DefaultStyleKeyProperty.OverrideMetadata(typeof(Day), new FrameworkPropertyMetadata(typeof(Day))); } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion } I've learned that you can't call a constructor that has parameters in XAML so the only way to actually set some data for this class is through the two properties, DayName and Date. I created a ControlTemplate for Day which is as follows: <Style TargetType="{x:Type con:Day}"> <Setter Property="MinHeight" Value="20"/> <Setter Property="MinWidth" Value="80"/> <Setter Property="Height" Value="20"/> <Setter Property="Width" Value="80"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type con:Day}"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Rectangle Grid.ColumnSpan="2" x:Name="rectHasEntry" Fill="WhiteSmoke"/> <TextBlock Grid.Column="0" x:Name="textBlockDayName" Text="{TemplateBinding DayName}" FontFamily="Junction" FontSize="11" Background="Transparent" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,2,0,0"/> <TextBlock Grid.Column="1" x:Name="textBlockDate" Text="{TemplateBinding Date}" FontFamily="Junction" FontSize="11" Background="Transparent" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,2,0,0"/> <Rectangle Grid.ColumnSpan="2" x:Name="rectMouseOver" Fill="#A2C0DA" Opacity="0" Style="{StaticResource DayRectangleMouseOverStyle}"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> I then render it on screen in my MainWindow thusly: <Window x:Class="WPFControlLibrary.TestHarness.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:con="clr-namespace:WPFControlLibrary.Calendar;assembly=WPFControlLibrary" Title="MainWindow" Height="500" Width="525" WindowStartupLocation="CenterScreen"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="80"/> </Grid.ColumnDefinitions> <con:Day Grid.Column="1" Height="20" Width="80" DayName="Mon" Date="1"/> </Grid> And what I actually see is, well, nothing. If I put my cursor on the con:Day line of the XAML it'll highlight the correctly sized rectangle in the window but I don't see "Mon" on the left side of the rectangle and "1" on the right. What am I doing wrong? I suspect it's something simple but I'll be darned if I'm seeing it. My ultimate goal is to group a bunch of the Day controls within a Month control, which is then contained in a Year control as I'm trying to make a long Calendar Bar that lets you navigate through the months and years, while clicking on a Day would display any information saved on that date. But I can't even get the Day part to display independent of anything else so I'm a long way from the rest of the functionality. Any help would be greatly appreciated.

  • Help needed with drawRect:

    - by Andrew Coad
    Hi, I'm having a fundamental issue with use of drawRect: Any advice would be greatly appreciated. The application needs to draw a variety of .png images at different times, sometimes with animation, sometimes without. A design goal that I was hoping to adhere to is to have the code inside drawRect: very simple and "dumb" - i.e. just do drawing and no other application logic. To draw the image I am using the drawAtPoint: method of UIImage. Since this method does not take a CGContext as a parameter, it can only be called within the drawRect: method. So I have: - (void)drawRect:(CGRect)rect { [firstImage drawAtPoint:CGPointMake(firstOffsetX, firstOffsetY)]; } All fine and dandy for one image. To draw multiple images (over time) the approach I have taken is to maintain an array of dictionaries with each dictionary containing an image, the point location to draw at and a flag to enable/suppress drawing for that image. I add dictionaries to the array over time and trigger drawing via the setNeedsDisplay: method of UIView. Use of an array of dictionaries allows me to completely reconstruct the entire display at any time. drawRect: now becomes: - (void)drawRect:(CGRect)rect { for (NSMutableDictionary *imageDict in [self imageDisplayList]) { if ([[imageDict objectForKey:@"needsDisplay"] boolValue]) { [[imageDict objectForKey:@"image"] drawAtPoint:[[imageDict objectForKey:@"location"] CGPointValue]]; [imageDict setValue:[NSNumber numberWithBool:NO] forKey:@"needsDisplay"]; } } } Still OK. The code is simple and compact. Animating this is where I run into problems. The first problem is where do I put the animation code? Do I put it in UIView or UIViewController? If in UIView, do I put it in drawRect: or elsewhere? Because the actual animation depends on the overall state of the application, I would need nested switch statements which, if put in drawRect:, would look something like this: - (void)drawRect:(CGRect)rect { for (NSMutableDictionary *imageDict in [self imageDisplayList]) { if ([[imageDict objectForKey:@"needsDisplay"] boolValue]) { switch ([self currentState]) { case STATE_1: switch ([[imageDict objectForKey:@"animationID"] intValue]) { case ANIMATE_FADE_IN: [self setAlpha:0.0]; [UIView beginAnimations:[[imageDict objectForKey:@"animationID"] intValue] context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; [UIView setAnimationDuration:2]; [self setAlpha:1.0]; break; case ANIMATE_FADE_OUT: [self setAlpha:1.0]; [UIView beginAnimations:[[imageDict objectForKey:@"animationID"] intValue] context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; [UIView setAnimationDuration:2]; [self setAlpha:0.0]; break; case ANIMATE_OTHER: // similar code here break; default: break; } break; case STATE_2: // similar code here break; default: break; } [[imageDict objectForKey:@"image"] drawAtPoint:[[imageDict objectForKey:@"location"] CGPointValue]]; [imageDict setValue:[NSNumber numberWithBool:NO] forKey:@"needsDisplay"]; } } [UIView commitAnimations]; } In addition, to make multiple sequential animations work correctly, there would need to be an outer controlling mechanism involving the animation delegate animationDidStop: callback that would set the needsDisplay entries in the dictionaries to allow/suppress drawing (and animation). The point that we are at now is that it all starts to look very ugly. More specifically: drawRect: starts to bloat quickly and contain code that is not "just drawing" code the UIView needs implicit awareness of the application state the overall process of drawing is now spread across three methods at a minimum And on to the point of this post: how can I do this better? What would the experts out there recommend in terms of overall structure? How can I keep application state information out of the view? Am I looking at this problem from the wrong direction. Is there some completely different approach that I should consider?

  • A ResetBindings on a BindingSource of a Grid also resets ComboBox

    - by Tetsuo
    Hi there, I have a DataGridView with a BindingSource of products. This products have an enum (Producer). For the most text fields (to edit the product) below the DataGridView I have a method RefreshProduct which does a ResetBindings in the end to refresh the DataGridView. There is a ComboBox (cboProducer), too. If I run over the _orderBs.ResetBindings(false) it will reset my cboProducer outside the DataGridView, too. Could you please help me to avoid this? Here follows some code; maybe it is then better to understand. public partial class SelectProducts : UserControl { private AutoCompleteStringCollection _productCollection; private ProductBL _productBL; private OrderBL _orderBL; private SortableBindingList<ProductBE> _listProducts; private ProductBE _selectedProduct; private OrderBE _order; BindingSource _orderBs = new BindingSource(); public SelectProducts() { InitializeComponent(); if (_productBL == null) _productBL = new ProductBL(); if (_orderBL == null) _orderBL = new OrderBL(); if (_productCollection == null) _productCollection = new AutoCompleteStringCollection(); if (_order == null) _order = new OrderBE(); if (_listProducts == null) { _listProducts = _order.ProductList; _orderBs.DataSource = _order; grdOrder.DataSource = _orderBs; grdOrder.DataMember = "ProductList"; } } private void cmdGetProduct_Click(object sender, EventArgs e) { ProductBE product = _productBL.Load(txtProductNumber.Text); _listProducts.Add(product); _orderBs.ResetBindings(false); } private void grdOrder_SelectionChanged(object sender, EventArgs e) { if (grdOrder.SelectedRows.Count > 0) { _selectedProduct = (ProductBE)((DataGridView)(sender)).CurrentRow.DataBoundItem; if (_selectedProduct != null) { txtArticleNumber.Text = _selectedProduct.Article; txtPrice.Text = _selectedProduct.Price.ToString("C"); txtProducerNew.Text = _selectedProduct.ProducerText; cboProducer.DataSource = Enum.GetValues(typeof(Producer)); cboProducer.SelectedItem = _selectedProduct.Producer; } } } private void txtProducerNew_Leave(object sender, EventArgs e) { string property = CommonMethods.GetPropertyName(() => new ProductBE().ProducerText); RefreshProduct(((TextBoxBase)sender).Text, property); } private void RefreshProduct(object value, string property) { if (_selectedProduct != null) { double valueOfDouble; if (double.TryParse(value.ToString(), out valueOfDouble)) { value = valueOfDouble; } Type type = _selectedProduct.GetType(); PropertyInfo info = type.GetProperty(property); if (info.PropertyType.BaseType == typeof(Enum)) { value = Enum.Parse(info.PropertyType, value.ToString()); } try { Convert.ChangeType(value, info.PropertyType, new CultureInfo("de-DE")); info.SetValue(_selectedProduct, value, null); } catch (Exception ex) { throw new WrongFormatException("\"" + value.ToString() + "\" is not a valid value.", ex); } var produktFromList = _listProducts.Single(p => p.Position == _selectedProduct.Position); info.SetValue(produktFromList, value, null); _orderBs.ResetBindings(false); } } private void cboProducer_SelectedIndexChanged(object sender, EventArgs e) { var selectedIndex = ((ComboBox)(sender)).SelectedIndex; switch ((Producer)selectedIndex) { case Producer.ABC: txtProducerNew.Text = Constants.ABC; break; case Producer.DEF: txtProducerNew.Text = Constants.DEF; break; case Producer.GHI: txtProducerNew.Text = Constants.GHI; break; case Producer.Another: txtProducerNew.Text = String.Empty; break; default: break; } string property = CommonMethods.GetPropertyName(() => new ProductBE().Producer); RefreshProduct(selectedIndex, property); } }

    Hi guys, has anyone come across any scenario wherein you needed to merge one object with another object of same type, merging the complete object graph. for e.g. If i have a person object and one person object is having first name and other the last name, some way to merge both the objects into a single object. public class Person { public Int32 Id { get; set; } public string FirstName { get; set; } public string LastName { get; set; } } public class MyClass { //both instances refer to the same person, probably coming from different sources Person obj1 = new Person(); obj1.Id=1; obj1.FirstName = "Tiju"; Person obj2 = new Person(); ojb2.Id=1; obj2.LastName = "John"; //some way of merging both the object obj1.MergeObject(obj2); //?? //obj1.Id // = 1 //obj1.FirstName // = "Tiju" //obj1.LastName // = "John" } I had come across such type of requirement and I wrote an extension method to do the same. public static class ExtensionMethods { private const string Key = "Id"; public static IList MergeList(this IList source, IList target) { Dictionary itemData = new Dictionary(); //fill the dictionary for existing list string temp = null; foreach (object item in source) { temp = GetKeyOfRecord(item); if (!String.IsNullOrEmpty(temp)) itemData[temp] = item; } //if the same id exists, merge the object, otherwise add to the existing list. foreach (object item in target) { temp = GetKeyOfRecord(item); if (!String.IsNullOrEmpty(temp) && itemData.ContainsKey(temp)) itemData[temp].MergeObject(item); else source.Add(item); } return source; } private static string GetKeyOfRecord(object o) { string keyValue = null; Type pointType = o.GetType(); if (pointType != null) foreach (PropertyInfo propertyItem in pointType.GetProperties()) { if (propertyItem.Name == Key) { keyValue = (string)propertyItem.GetValue(o, null); } } return keyValue; } public static object MergeObject(this object source, object target) { if (source != null && target != null) { Type typeSource = source.GetType(); Type typeTarget = target.GetType(); //if both types are same, try to merge if (typeSource != null && typeTarget != null && typeSource.FullName == typeTarget.FullName) if (typeSource.IsClass && !typeSource.Namespace.Equals("System", StringComparison.InvariantCulture)) { PropertyInfo[] propertyList = typeSource.GetProperties(); for (int index = 0; index < propertyList.Length; index++) { Type tempPropertySourceValueType = null; object tempPropertySourceValue = null; Type tempPropertyTargetValueType = null; object tempPropertyTargetValue = null; //get rid of indexers if (propertyList[index].GetIndexParameters().Length == 0) { tempPropertySourceValue = propertyList[index].GetValue(source, null); tempPropertyTargetValue = propertyList[index].GetValue(target, null); } if (tempPropertySourceValue != null) tempPropertySourceValueType = tempPropertySourceValue.GetType(); if (tempPropertyTargetValue != null) tempPropertyTargetValueType = tempPropertyTargetValue.GetType(); //if the property is a list IList ilistSource = tempPropertySourceValue as IList; IList ilistTarget = tempPropertyTargetValue as IList; if (ilistSource != null || ilistTarget != null) { if (ilistSource != null) ilistSource.MergeList(ilistTarget); else propertyList[index].SetValue(source, ilistTarget, null); } //if the property is a Dto else if (tempPropertySourceValue != null || tempPropertyTargetValue != null) { if (tempPropertySourceValue != null) tempPropertySourceValue.MergeObject(tempPropertyTargetValue); else propertyList[index].SetValue(source, tempPropertyTargetValue, null); } } } } return source; } } However, this works when the source property is null, if target has it, it will copy that to source. IT can still be improved to merge when inconsistencies are there e.g. if FirstName="Tiju" and FirstName="John" Any commments appreciated. Thanks TJ

  • Change form field options dynamically (and restore previously selected options) using jQuery

    - by Martin
    I'm fairly new to both jQuery and JavaScript so can anyone please point out what I'm missing here? I have a form with multiple pairs of select fields, where the content of the second field relies on the selection of the first one. Once a value is chosen from the first one then a piece of jQuery code empties the corresponding second select options, gets new values as JSON and inserts them as new select values. All of this works with the code I've written. However if a user has chosen a second value, I'd like to restore it if possible (meaning if the new values also include the one previously selected). I tried to do this by first saving the second value and then trying to set it once the new options have been inserted. This did not work. However when trying to debug I inserted an alert() just before restoring the second value and with that in there it does work... Am I missing something very basic here? Any help would be appreciated. HTML: <select name="party-0-first" id="id_party-0-first"> <option value="" selected="selected">---------</option> <option value="1">first_value1</option> <option value="2">first_value2</option> <option value="3">first_value3</option> <option value="4">first_value4</option> </select> <select name="party-0-second" id="id_party-0-second"> <option value="" selected="selected">---------</option> <option value="1">second_value1</option> <option value="2">second_value2</option> <option value="3">second_value3</option> <option value="4">second_value4</option> </select> <select name="party-1-first" id="id_party-1-first"> ... JavaScript: $.fn.setSecond = function() { var divName = $(this).attr("name"); divName = divName.replace('-first', ''); divName = divName.replace('party-', ''); // Save the currently selected value of the "second" select box // This seems to work properly setValue = $('#id_party-' + divName + '-second').val(); // Get the new values $.getJSON("/json_opsys/", { client: $(this).val() }, function(data){ $('#id_party-' + divName + '-second').empty(); $('#id_party-' + divName + '-second').append('<option value="" selected="selected">---------</option>'); $.each(data, function(i, item){ $('#id_party-' + divName + '-second').append('<option value="' + item.pk + '">' + item.fields.name + '</option>'); }); }); // Here I try to restore the selected value // This does not work normally, however if I place a javascript alert() before // this for some reason it does work $('#id_party-' + divName + '-second').val(setValue); $(document).ready(function(){ $('[id*=first]').change(function() { $(this).setSecond(); }); });

  • Configurable Values in Enum

    - by Omer Akhter
    I often use this design in my code to maintain configurable values. Consider this code: public enum Options { REGEX_STRING("Some Regex"), REGEX_PATTERN(Pattern.compile(REGEX_STRING.getString()), false), THREAD_COUNT(2), OPTIONS_PATH("options.config", false), DEBUG(true), ALWAYS_SAVE_OPTIONS(true), THREAD_WAIT_MILLIS(1000); Object value; boolean saveValue = true; private Options(Object value) { this.value = value; } private Options(Object value, boolean saveValue) { this.value = value; this.saveValue = saveValue; } public void setValue(Object value) { this.value = value; } public Object getValue() { return value; } public String getString() { return value.toString(); } public boolean getBoolean() { Boolean booleanValue = (value instanceof Boolean) ? (Boolean) value : null; if (value == null) { try { booleanValue = Boolean.valueOf(value.toString()); } catch (Throwable t) { } } // We want a NullPointerException here return booleanValue.booleanValue(); } public int getInteger() { Integer integerValue = (value instanceof Number) ? ((Number) value).intValue() : null; if (integerValue == null) { try { integerValue = Integer.valueOf(value.toString()); } catch (Throwable t) { } } return integerValue.intValue(); } public float getFloat() { Float floatValue = (value instanceof Number) ? ((Number) value).floatValue() : null; if (floatValue == null) { try { floatValue = Float.valueOf(value.toString()); } catch (Throwable t) { } } return floatValue.floatValue(); } public static void saveToFile(String path) throws IOException { FileWriter fw = new FileWriter(path); Properties properties = new Properties(); for (Options option : Options.values()) { if (option.saveValue) { properties.setProperty(option.name(), option.getString()); } } if (DEBUG.getBoolean()) { properties.list(System.out); } properties.store(fw, null); } public static void loadFromFile(String path) throws IOException { FileReader fr = new FileReader(path); Properties properties = new Properties(); properties.load(fr); if (DEBUG.getBoolean()) { properties.list(System.out); } Object value = null; for (Options option : Options.values()) { if (option.saveValue) { Class<?> clazz = option.value.getClass(); try { if (String.class.equals(clazz)) { value = properties.getProperty(option.name()); } else { value = clazz.getConstructor(String.class).newInstance(properties.getProperty(option.name())); } } catch (NoSuchMethodException ex) { Debug.log(ex); } catch (InstantiationException ex) { Debug.log(ex); } catch (IllegalAccessException ex) { Debug.log(ex); } catch (IllegalArgumentException ex) { Debug.log(ex); } catch (InvocationTargetException ex) { Debug.log(ex); } if (value != null) { option.setValue(value); } } } } } This way, I can save and retrieve values from files easily. The problem is that I don't want to repeat this code everywhere. Like as we know, enums can't be extended; so wherever I use this, I have to put all these methods there. I want only to declare the values and that if they should be persisted. No method definitions each time; any ideas?

  • Foreign key not stored in child entity (one-to-many)

    - by Kamil Los
    Hi, I'm quite new to hibernate and have stumbled on this problem, which I can't find solution for. When persisting parent object (with one-to-many relationship with child), the foreign-key to this parent is not stored in child's table. My classes: Parent.java @javax.persistence.Table(name = "PARENT") @Entity public class PARENT { private Integer id; @javax.persistence.Column(name = "ID") @Id @GeneratedValue(strategy=GenerationType.AUTO) public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } private Collection<Child> children; @OneToMany(mappedBy = "parent", fetch = FetchType.EAGER, cascade = {CascadeType.ALL}) @Cascade({org.hibernate.annotations.CascadeType.ALL}) public Collection<Child> getChildren() { return children; } public void setChildren(Collection<Child> children) { this.children = children; } } Child.java @javax.persistence.Table(name = "CHILD") @Entity @IdClass(Child.ChildId.class) public class Child { private String childId1; @Id public String getChildId1() { return childId1; } public void setChildId1(String childId1) { this.childId1 = childId1; } private String childId2; @Id public String getChildId2() { return childId2; } public void setChildId2(String childId2) { this.childId2 = childId2; } private Parent parent; @ManyToOne @javax.persistence.JoinColumn(name = "PARENT_ID", referencedColumnName = "ID") public Parent getParent() { return parent; } public void setParent(Operation parent) { this.parent = parent; } public static class ChildId implements Serializable { private String childId1; @javax.persistence.Column(name = "CHILD_ID1") public String getChildId1() { return childId1; } public void setChildId1(String childId1) { this.childId1 = childId1; } private String childId2; @javax.persistence.Column(name = "CHIILD_ID2") public String getChildId2() { return childId2; } public void setChildId2(String childId2) { this.childId2 = childId2; } public ChildId() { } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; ChildId that = (ChildId) o; if (childId1 != null ? !childId1.equals(that.childId1) : that.childId1 != null) return false; if (childId2 != null ? !childId2.equals(that.childId2) : that.childId2 != null) return false; return true; } @Override public int hashCode() { int result = childId1 != null ? childId1.hashCode() : 0; result = 31 * result + (childId2 != null ? childId2.hashCode() : 0); return result; } } } Test.java public class Test() { private ParentDao parentDao; public void setParentDao(ParentDao parentDao) { this.parentDao = parentDao; } private ChildDao childDao; public void setChildDao(ChildDao childDao) { this.childDao = parentDao; } test1() { Parent parent = new Parent(); Child child = new Child(); child.setChildId1("a"); child.setChildId2("b"); ArrayList<Child> children = new ArrayList<Child>(); children.add(child); parent.setChildren(children); parent.setValue("value"); parentDao.save(parent); //calls hibernate's currentSession.saveOrUpdate(entity) } test2() { Parent parent = new Parent(); parent.setValue("value"); parentDao.save(parent); //calls hibernate's currentSession.saveOrUpdate(entity) Child child = new Child(); child.setChildId1("a"); child.setChildId2("b"); child.setParent(parent); childDao.save(); //calls hibernate's currentSession.saveOrUpdate(entity) } } When calling test1(), both entities get written to database, but field PARENT_ID in CHILD table stays empty. The only workaround I have so far is test2() - persisting parent first, and then the child. My goal is to persist parent and its children in one call to save() on Parent. Any ideas?

  • ZF: Form array field - how to display values in the view correctly

    - by Wojciech Fracz
    Let's say I have a Zend_Form form that has a few text fields, e.g: $form = new Zend_Form(); $form->addElement('text', 'name', array( 'required' => true, 'isArray' => true, 'filters' => array( /* ... */ ), 'validators' => array( /* ... */ ), )); $form->addElement('text', 'surname', array( 'required' => true, 'isArray' => true, 'filters' => array( /* ... */ ), 'validators' => array( /* ... */ ), )); After rendering it I have following HTML markup (simplified): <div id="people"> <div class="person"> <input type="text" name="name[]" /> <input type="text" name="surname[]" /> </div> </div> Now I want to have the ability to add as many people as I want. I create a "+" button that in Javascript appends next div.person to the container. Before I submit the form, I have for example 5 names and 5 surnames, posted to the server as arrays. Everything is fine unless somebody puts the value in the field that does not validate. Then the whole form validation fails and when I want to display the form again (with errors) I see the PHP Warning: htmlspecialchars() expects parameter 1 to be string, array given Which is more or less described in ticket: http://framework.zend.com/issues/browse/ZF-8112 However, I came up with a not-very-elegant solution. What I wanted to achieve: have all fields and values rendered again in the view have error messages only next to the fields that contained bad values Here is my solution (view script): <div id="people"> <?php $names = $form->name->getValue(); // will have an array here if the form were submitted $surnames= $form->surname->getValue(); // only if the form were submitted we need to validate fields' values // and display errors next to them; otherwise when user enter the page // and render the form for the first time - he would see Required validator // errors $needsValidation = is_array($names) || is_array($surnames); // print empty fields when the form is displayed the first time if(!is_array($names))$names= array(''); if(!is_array($surnames))$surnames= array(''); // display all fields! foreach($names as $index => $name): $surname = $surnames[$index]; // validate value if needed if($needsValidation){ $form->name->isValid($name); $form->surname->isValid($surname); } ?> <div class="person"> <?=$form->name->setValue($name); // display field with error if did not pass the validation ?> <?=$form->surname->setValue($surname);?> </div> <?php endforeach; ?> </div> The code work, but I want to know if there is an appropriate, more comfortable way to do this? I often hit this problem when there is a need for a more dynamic - multivalue forms and have not find better solution for a long time.

  • Java error starting with "log4j:WARN No appenders could be found for logger" in ZuckerReports SugarC

    - by Tom McDonnell
    Greetings all. I apologise for posting this problem here, but I do so in desperation after receiving no response on the SugarCRM forums. Even if a reader is unfamiliar with ZuckerReports or SugarCRM some general advice on Java may be of use to me. I have installed ZuckerReports v1.12 in SugarCRM 5.5.1. When I attempt to run a report I get the following error message. cmdline: javaw -classpath

The installation in which the report runs correctly is of the same version, and has the same version of the ZuckerReports module. The report previously ran correctly on both installations. I think that the only changes that have been made on the installation in which the report now does not work since the report was last successfully run are the additions of a few custom fields in the Contacts module. These changes should have nothing to do with ZuckerReports. I have tried uninstalling and reinstalling the ZuckerReports module, but the problem remains. A google search for the warnings given in the error message ie. * log4j:WARN No appenders could be found for logger (net.sf.jasperreports.extensions.ExtensionsEnviron ment). * log4j:WARN Please initialize the log4j system properly. Returns a few links (not specific to ZuckerReports) with tips similar to the following: * log4j.properties or log4j.xml needs to be on the classpath where log4j can find it. I cannot find a file with either of those names anywhere on my server, and yet the report can be run successfully on one of my SugarCRM installations. So I figure log4j must be being configured another way. Can anyone suggest a way to solve this problem? Or explain how I might discover how log4j is configured in ZuckerReports? Or explain how I might compare the working with the non-working installation in order to help find a solution? (I have tried searching for files containing "log4j" in both installations and comparing but all I can find are .jar files (nothing I can read with a text editor), and the .jar files found in each installation appear to be the same.)

  • C# Using Reflection to copy base class properties

    - by David Liddle
    I would like to update all properties from MyObject to another using Reflection. The problem I am coming into is that the particular object is inherited from a base class and those base class property values are not updated. The below code copies over top level property values. public void Update(MyObject o) { MyObject copyObject = ... FieldInfo[] myObjectFields = o.GetType().GetFields( BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance); foreach (FieldInfo fi in myObjectFields) { fi.SetValue(copyObject, fi.GetValue(o)); } } I was looking to see if there were any more BindingFlags attributes I could use to help but to no avail.

  • NSUserDefaults in monotouch

    - by Ali Shafai
    I'm very impressed with MonoTouch.Dialog by Miguel. inspired by his simple approach I thought it would be very nice to have a reflection based NSUserDefaults class that works seamlessly by marking certain properties as "persistable in user defaults" and forget about the rest. something like this: public class SomeController { [PersistInUserSettings] public string LastPostUserRead { get; set; } } I don't like the LastPostUserRead to be of type "UserSetting", I like it to be a normal property so that later I can assign to it like: LastPostUserRead = "Post 1"; and not like: LastPostUserRead.SetValue("Post 1"); Any idea on how to implement it (without Reflection.Emit) in monotouch?

  • .NET How can i set field value on value type using reflection

    .NET I want to clone a value type's fields. How can i set a field value on a value type using reflection (or something else dynamically)? This works for reference types but not for value types. I understand why but I don't know an alternative. shared function clone(of t)(original as t) as t dim cloned as t 'if class then execute parameterless constructor if getType(t).isClass then cloned = reflector.construct(of t)() dim public_fields = original.getType.getFields() for each field in public_fields dim original_value = field.getValue(original) 'this won't work for value type, but it does work for reference type ??? field.setValue(cloned, original_value) next return cloned end function

    Hi All, I've got the next code: listModel = new DefaultListModel(); listModel.addElement(dateFormat.format(new Date()) + ": Msg1"); messageList = new JList(listModel); messageList.setLayoutOrientation(JList.VERTICAL); messageScrollList = new JScrollPane(messageList); messageScrollList.setPreferredSize(new Dimension(500, 200)); messageScrollList.getVerticalScrollBar().addAdjustmentListener(new AdjustmentListener() { public void adjustmentValueChanged(AdjustmentEvent e) { e.getAdjustable().setValue(e.getAdjustable().getMaximum()); } }); It auto scrolls down. But, if I try to scroll back up to re-read a message, it forces a scroll down. How can I fix this?

  • WPF TypeConverter ConvertTo not firing

    - by JFoulkes
    Hi, I have a dependency property in a class which I need to be converted to a string. I have added the TypeConverty attribute on the property. The type I am converting is the .net Style class. [TypeConverter(typeof(BulletStyleTypeConverter))] public Style BulletStyle { get { return (Style)GetValue(BulletStyleProperty); } set { this.SetValue(BulletStyleProperty, value); } } When I put the string "Rectangle" in for BulletStyle in xaml it hits the ConvertFrom method in my converter. However, when I use XamlWriter.Save() to serialise this, the property does not appear as an attribute in the string which is produced. I have implemented ConvertTo and put a breakpoint on, which is never hit. I have implemented CanConvertTo and put a breakpoint on, which IS hit and returns true. So i'm stumped as to why ConvertTo never fires.
