  • Tmp issues with java service on windows 2008 service

    - by Mans
    Hello! I am having a rather nasty problem with windows 2008 server. We have a java application that is running as a service using the local services user. The problem is this user does not have access to read/write to the specified java tmp directory (specified by the system). This means that every time the application tries to create a tmp file an IOException is thrown. Is there any way to make a java application that need access to the tmp directory run as a service without: Creating a new user specifically for the purspose Specifying a new tmp directory (which you will have to clean up yourself)

  • c# - clear surface when resizing

    - by dhh
    Hello, I'm trying to build my own custom control for a windows forms application in C#.Net. Currently I paint some rectangles and other graphic elements using the paint event. When I now resize the app form to fit the desktop size, all elements are repainted (which is exactly the behaviour I need) but the old one's are shown in the background. Here's what I'm doing by now: Pen penDefaultBorder = new Pen(Color.Wheat, 1); int margin = 5; private void CustomControl_Paint(object sender, PaintEventArgs e) { CustomControl calendar = (CustomControl)sender; Graphics graphics = e.Graphics; graphics.Clear(Color.WhiteSmoke); graphics.DrawRectangle(penDefaultBorder, margin, margin, calendar.Width - margin * 2, calendar.Height - margin * 2); //... } Neither the graphics.Clear, nor adding a graphics.FillRectangle(...) will hide the old rectangle from the surface. Ideas? Thank you all.

  • C# custom control to get internal text as string

    - by Ed Woodcock
    ok, I'm working on a custom control that can contain some javascript, and read this out of the page into a string field. This is a workaround for dynamic javascript inside an updatepanel. At the moment, I've got it working, but if I try to put a server tag inside the block: <custom:control ID="Custom" runat="server"> <%= ControlName.ClientID %> </custom:control> The compiler does not like it. I know these are generated at runtime, and so might not be compatible with what I'm doing, but does anyone have any idea how I can get that working? EDIT Error message is: Code blocks are not supported in this context EDIT 2 The control: [DataBindingHandler("System.Web.UI.Design.TextDataBindingHandler, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"), ControlValueProperty("Text"), DefaultProperty("Text"), ParseChildren(true, "Text"), AspNetHostingPermission(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal), AspNetHostingPermission(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)] public class CustomControl : Control, ITextControl { [DefaultValue(""), Bindable(true), Localizable(true)] public string Text { get { return (string)(ViewState["Text"] ?? string.Empty); } set { ViewState["Text"] = value; } } }

  • RectangleGeometry with relative dimensions... how?

    - by Padu Merloti
    I'm trying to replicate the nowadays so fashionable "reflex" effect on a controltemplate for buttons I'm creating. The basic idea is to create a rectangle with a gradient fill from white to transparent and then clip some of that semi-transparent rectangle with a rectanglegeometry. The problem is that I don't know how to define a relative rectangle geometry. I kind of worked around width by defining a large value (1000), but height is a problem. For example, it works good for buttons that have a 200 height, but doesn't do anything for smaller buttons. Any ideas? <Rectangle RadiusX="5" RadiusY="5" StrokeThickness="1" Stroke="Transparent"> <Rectangle.Fill> <LinearGradientBrush StartPoint="0,0" EndPoint="0,0.55"> <GradientStop Color="#66ffffff" Offset="0.0" /> <GradientStop Color="Transparent" Offset="1.0" /> </LinearGradientBrush> </Rectangle.Fill> <Rectangle.Clip> <RectangleGeometry Rect="0,0,1000,60" /> </Rectangle.Clip> </Rectangle>

  • how to create Custom Server control for GridView using C#.net

    - by Dhanapal
    Hi, I want to created a Custom Server Control (Inherited from GridView). On the page, the GridView is DataBound to a DataSet, so I do not know at design time what columns will be present in my GridView. Now, what I want to do is, to add a textbox in every Cell for the GridView Header row, and those textboxes will control column filtering.

  • Diffrernce between BackgroundWorker.ReportProgress() and Control.Invoke()

    - by ohadsc
    What is the difference between options 1 and 2 in the following? private void BGW_DoWork(object sender, DoWorkEventArgs e) { for (int i=1; i<=100; i++) { string txt = i.ToString(); if (Test_Check.Checked) //OPTION 1 Test_BackgroundWorker.ReportProgress(i, txt); else //OPTION 2 this.Invoke((Action<int, string>)UpdateGUI, new object[] {i, txt}); } } private void BGW_ProgressChanged(object sender, ProgressChangedEventArgs e) { UpdateGUI(e.ProgressPercentage, (string)e.UserState); } private void UpdateGUI(int percent, string txt) { Test_ProgressBar.Value = percent; Test_RichTextBox.AppendText(txt + Environment.NewLine); } Looking at reflector, the Control.Invoke() appears to use: this.FindMarshalingControl().MarshaledInvoke(this, method, args, 1); whereas BackgroundWorker.Invoke() appears to use: this.asyncOperation.Post(this.progressReporter, args); (I'm just guessing these are the relevant function calls.) If I understand correctly, BGW Posts to the WinForms window its progress report request, whereas Control.Invoke uses a CLR mechanism to invoke on the right thread. Am I close? And if so, what are the repercussions of using either ? Thanks

  • JQuery validation not working for checkbox group

    - by Chris Halcrow
    I'm having trouble getting JQuery validation to work with a set of checkboxes. I'm generating the checkboxes using an ASP.NET checkboxlist, and I've used JQuery to set the 'name' attribute to the same thing for each checkbox in the list. Here's the code that gets written to the browser. I'm setting the 'validate' attribute on the 1st checkbox to set the rule that at least one checkbox must be selected. The JQuery validation works for all other elements on the form, but not for the checkbox list. I'm also using a JQuery form wizard on the page which triggers validation for each 'page' of the form, so I don't have control over how the validation is called. <input id="ContentPlaceHolder1_MainContent_AreaOfInterest_0" class="ui-wizard-content ui-helper-reset ui-state-default" type="checkbox" value="Famine" name="hello[]" validate="required:true, minlength:1"> <label for="ContentPlaceHolder1_MainContent_AreaOfInterest_0">Famine</label> <br> <input id="ContentPlaceHolder1_MainContent_AreaOfInterest_1" class="ui-wizard-content ui-helper-reset ui-state-default" type="checkbox" value="Events Volunteer" name="hello[]"> <label for="ContentPlaceHolder1_MainContent_AreaOfInterest_1">Events Volunteer</label> Any ideas on what's going wrong? There are lots of examples of JQuery scripts that will do the validation, however I'm trying to avoid this as I'm generating the checkboxlist server side by a custom control so that it can be re-used across different pages that may or may not have JQuery enabled. I'm trying to enable the JQuery validation whilst being as unobtrusive as possible, so that pages will still work even if JQuery is disabled. Here are the relevant JQuery inclusions and JQuery initialisation script for the form wizard. I'm not using any initialisation code for JQuery validation: <script type="text/javascript" src="../js/formwizard/js/bbq.js"></script> <script type="text/javascript" src="../js/formwizard/js/jquery.form.js"></script> <script type="text/javascript" src="../js/formwizard/js/jquery.form.wizard.js"></script> <script type="text/javascript" src="../js/formwizard/js/jquery.validate.js"></script> <script type="text/javascript"> $(document).ready(function () { $("#form1").formwizard({ validationEnabled: true, focusFirstInput: true }); }); </script>

  • How to listen for AffectsParentArrange events when you're not the parent

    - by Jeff B
    There is an attribute "AffectsParentArrange" that implicitly invalidates the parent's layout - but I want to attach an event handler to the "event" triggered by that attribute. When a child property with the attribute changes, the parent's arrangement is invalidated. I have a custom control (which is not the immediate parent) that needs to receive an event. Does anyone know of an event that can be used here? Do I need to provide a custom parent that overrides a method and fires an event?

  • How to give a custom ASP.NET control the ability to parse XML markup to a collection?

    - by Vilx-
    I'm writing a custom ASP.NET webcontrol and would like it to have a collection of custom items which can also be specified in the XML markup. Something like this: class MyControl: WebControl { public IList<MyItemType> MyItems { get; private set; } } And in the markup: <asd:MyControl runat="server" id="mc1"> <MyItems> <MyDerivedCustomItem asd="dsa"/> <MyOtherDerivedCustomItem asd="dsa"/> </MyItems> </asd:MyControl> How do I do this? I though this was all about implementing some interface on the collection or adding some special attributes to the property, but nothing I do seems to work.

  • How to draw complex shape from code behind for custom control in resource dictionary

    - by HopelessCoder
    Hi I am new to wpf and am having a problem which may or may not be trivial. I have defined a custom control as follows in the resource dictionary: <ResourceDictionary x:Class="SyringeSlider.Themes.Generic" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:SyringeSlider"> <Style TargetType="{x:Type local:CustomControl1}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:CustomControl1}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> <Canvas Height="{TemplateBinding Height}" Width="{TemplateBinding Width}" Name="syringeCanvas"> </Canvas> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary> Unfortunately I cannot go beyond this because I would like to draw a geometry onto the canvas consisting of a set of multiple line geometries whose dimensions are calculated as a function of the space available in the canvas. I believe that I need a code behind method to do this, but have not been able to determine how to link the xaml definition to a code behind method. Note that I have set up a class x:Class="SyringeSlider.Themes.Generic" for specifically this purpose, but can't figure out which Canvas property to link the drawing method to. My drawing method looks like this private void CalculateSyringe() { int adjHeight = (int) Height - 1; int adjWidth = (int) Width - 1; // Calculate some very useful values based on the chart above. int borderOffset = (int)Math.Floor(m_borderWidth / 2.0f); int flangeLength = (int)(adjHeight * .05f); int barrelLeftCol = (int)(adjWidth * .10f); int barrelLength = (int)(adjHeight * .80); int barrelRightCol = adjWidth - barrelLeftCol; int coneLength = (int)(adjHeight * .10); int tipLeftCol = (int)(adjWidth * .45); int tipRightCol = adjWidth - tipLeftCol; int tipBotCol = adjWidth - borderOffset; Path mySyringePath = new Path(); PathGeometry mySyringeGeometry = new PathGeometry(); PathFigure mySyringeFigure = new PathFigure(); mySyringeFigure.StartPoint = new Point(0, 0); Point pointA = new Point(0, flangeLength); mySyringeFigure.Segments.Add(new LineSegment(pointA, true)); Point pointB = new Point(); pointB.Y = pointA.Y + barrelLength; pointB.X = 0; mySyringeFigure.Segments.Add(new LineSegment(pointB, true)); // You get the idea....Add more points in this way mySyringeGeometry.Figures.Add(mySyringeFigure); mySyringePath.Data = mySyringeGeometry; } SO my question is: 1) Does what I am trying to do make any sense? 2) Can a use a canvas for this purpose? If not, what are my other options? Thanks!

  • Stretch panel with splitter

    - by user1153896
    I want to implement a basic WPF layout with three panels and two splitters (Horizontal and Vertical splitter). Two panels on the left and on the bottom has to be callapsable and one panel has to stretch accordingly. Here is a simple XAML: <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="5"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <StackPanel Background="Aqua" Grid.Column="0" Name="leftPanel" > <TextBlock FontSize="35" Foreground="#58290A" TextWrapping="Wrap">Left Hand Side</TextBlock> </StackPanel> <GridSplitter Grid.Column="1" HorizontalAlignment="Stretch"/> <Grid Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="5" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Label Content="... Clien Area .. Has to Stretch vertically and horizontally" Margin="10"></Label> <Button Click="LeftButton_Click" Margin="10">Close Left Panel</Button> <Button Click="BottomButton_Click" Margin="10">Close Bottom Panel</Button> </StackPanel> <GridSplitter Grid.Row="1" Background="Gray" HorizontalAlignment="Stretch"/> <ListBox Grid.Row="2" Background="Violet" Name="bottomPanel"> <ListBoxItem>Hello</ListBoxItem> <ListBoxItem>World</ListBoxItem> </ListBox> </Grid> </Grid> and codebehind: private void LeftButton_Click(object sender, RoutedEventArgs e) { leftPanel.Visibility = (leftPanel.Visibility == System.Windows.Visibility.Visible)? System.Windows.Visibility.Collapsed : System.Windows.Visibility.Visible; } private void BottomButton_Click(object sender, RoutedEventArgs e) { bottomPanel.Visibility = (bottomPanel.Visibility == System.Windows.Visibility.Visible) ? System.Windows.Visibility.Collapsed : System.Windows.Visibility.Visible; } This code doesn't work as expected :(. Any WPF experts around? to suggest a solution for having Client Area (stretched) and splitter at the same time? DockPanel will work perfectly, but I need splitter! Thanks.

  • WPF: How to properly override the methods when creating custom control

    - by EV
    Hi, I am creating a custom control Toolbox that is derived from ItemsControl. This toolbox is supposed to be filled with icons coming from the database. The definition looks like this: public class Toolbox : ItemsControl { protected override DependencyObject GetContainerForItemOverride() { return new ToolboxItem(); } protected override bool IsItemItsOwnContainerOverride(object item) { return (item is ToolboxItem); } } Toolboxitem is derived from ContentControl. public class ToolboxItem : ContentControl { static ToolboxItem() { FrameworkElement.DefaultStyleKeyProperty.OverrideMetadata(typeof(ToolboxItem), new FrameworkPropertyMetadata(typeof(ToolboxItem))); } } Since the number of icons stored in a database is not known I want to use the data template: <DataTemplate x:Key="ToolBoxTemplate"> <StackPanel> <Image Source="{Binding Path=url}" /> </StackPanel> </DataTemplate> Then I want the Toolbox to use the template. <Toolbox x:Name="NewLibrary" ItemsSource="{Binding}" ItemTemplate="ToolBoxtemplate"> </Toolbox> I'm using ADO.NET entity framework to connect to a database. The code behind: SystemicsAnalystDBEntities db = new SystemicsAnalystDBEntities(); private void Window_Loaded(object sender, RoutedEventArgs e) { NewLibrary.ItemsSource = from c in db.Components select c; } However, there is a problem. When the code is executed, it displays the object from the database (as the ItemSource property is set to the object from the database) and not the images. It does not use the template. When I use the static images source it works in the right way I found out that I need to override the PrepareContainerForItemOverride method.But I don't know how to add the template to it. Thanks a lot for any comments. Additional Information Here is the ControlTemplate for ToolboxItem: <ControlTemplate TargetType="{x:Type s:ToolboxItem}"> <Grid> <Rectangle Name="Border" StrokeThickness="1" StrokeDashArray="2" Fill="Transparent" SnapsToDevicePixels="true" /> <ContentPresenter Content="{TemplateBinding ContentControl.Content}" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" /> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="true"> <Setter TargetName="Border" Property="Stroke" Value="Gray" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate>

  • Reading an embedded file from an ASP.NET Custom Server Control an rendering it

    I currently have a file "abc.htm" in my Custom Server Control Project and it's Build Action is set to Embedded Resource.

  • UISegemnted COntrol - selecting 3rd segment activates second segment

    - by diggers25
    I have a segmented control with 3 defined segments. i am looking to capture the segment index so I can use it in an if statement to update variables accordingly as such: -(IBAction)numPlayers:(id)sender; { numPlayersSegment = [(UISegmentedControl *)sender retain]; if (numPlayersSegment.selectedSegmentIndex == 0) { numOfPlayers = 2; } else if (numPlayersSegment.selectedSegmentIndex = 1) { numOfPlayers = 3; } else if (numPlayersSegment.selectedSegmentIndex = 2) { numOfPlayers = 4; } else if (numPlayersSegment.selectedSegmentIndex = -1) { numOfPlayers = 0; } NSLog(@"Players selected = %d", numPlayersSegment.selectedSegmentIndex); However whenever I press the third segment (index 2) it returns the value of the second segment (index 1) and also highlights the 2nd segment. I can see nothing untoward in IB. Has anybody seen this and have any suggestions. I am using xcode 3.2.1 on snow leopard thanks

  • Windows media player control with .NET

    - by brovar
    What I want to do is to read media files (pics and videos) from a directory and display them one by one using the WMP control (AxWMPLib.AxWindowsMediaPlayer). In its older version it was enough to check the file's duration to distinguish images from videos, the new one randomly shows movies' duration properly or as zero. Does anyone know any other way of finding out what file is being proceeded withouth checking its extension (as a file can have an extension of .abc or so)? I'll be very grateful for any help. (Sorry for my lousy English.)
