Take the following steps to create and run a program that implements non-automated
annotations, This program will let you create a Note and a button annotations, set
the user mode through a menu, and activate the annotations by left clicking on the
annotation.
Start Visual Studio .NET. Choose File->New->Project… from the menu. In the New Project dialog box, choose either "Visual C# Projects" - NET Framework 3.0 or "Visual Basic Projects" - NET Framework 3.0 in the Projects Type List, and choose "Windows Application (WPF) " in the Templates List. Type the project name as "Using Non Automated Annotations in Run Mode" in the Project Name field, and then choose OK. If desired, type a new location for your project or select a directory using the Browse button, and then choose OK . In the "Solution Explorer" window, right-click on the "References" folder (For a VB project, right-click on the project file in solution explorer), and select "Add Reference…" from the context menu. In the "Add Reference" dialog box, select the ".NET" tab and browse to Leadtools For .NET "\LEAD Technologies\LEADTOOLS 16\Bin\DotNet\Win32 " folder and select the following DLLs: Leadtools.Windows.Annotations.dll Leadtools.Windows.Controls.dll Leadtools.Windows.Media.Transitions.dll
Open Window1.xaml file and replace it by the following: [Visual Basic] <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Using_Non_Automated_Annotations_in_Run_Mode" Height="300" Width="300" Loaded="WindowLoaded" xmlns:Leadtools_Windows_Controls="clr-namespace:Leadtools.Windows.Controls;assembly=Leadtools.Windows.Controls" > <StackPanel> <RadioButton Name="rbDesignMode" GroupName="UserMode" Content="Design Mode" IsChecked="True" Checked="CheckedChanged"/> <RadioButton Name="rbRunMode" GroupName="UserMode" Content="Run Mode" Checked="CheckedChanged"/> <Separator/> <Leadtools_Windows_Controls:BitmapSourceViewer x:Name="imageViewer1" Width="NaN" Height="NaN"/> </StackPanel> </Window>
<Window x:Class="Using_Non_Automated_Annotations_in_Run_Mode.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Using_Non_Automated_Annotations_in_Run_Mode" Height="300" Width="300" Loaded="WindowLoaded" xmlns:Leadtools_Windows_Controls="clr-namespace:Leadtools.Windows.Controls;assembly=Leadtools.Windows.Controls" > <StackPanel> <RadioButton Name="rbDesignMode" GroupName="UserMode" Content="Design Mode" IsChecked="True" Checked="CheckedChanged"/> <RadioButton Name="rbRunMode" GroupName="UserMode" Content="Run Mode" Checked="CheckedChanged"/> <Separator/> <Leadtools_Windows_Controls:BitmapSourceViewer x:Name="imageViewer1" Width="NaN" Height="NaN"/> </StackPanel> </Window>
Switch to Window1 code view (for VB project right-click Window1 in the solution explorer then select View Code and for C# project open Window1.xaml.cs file) and add the following lines at the beginning of the file: [Visual Basic] Imports Leadtools.Windows.Annotations
using Leadtools.Windows.Annotations;
Declare the following private enumeration: [Visual Basic] ' user mode Private Enum UserModeEnum RunMode DesignMode End Enum
// user mode private enum UserModeEnum { RunMode, DesignMode }
Declare the following private variables: [Visual Basic] ' Annotation container object Private annContainerObj As AnnContainer ' Current user mode Private currentUserMode As UserModeEnum
// Annotation container object private AnnContainer annContainerObj; // Current user mode private UserModeEnum currentUserMode;
Add the following functions code to class Window1: [Visual Basic] Private Sub WindowLoaded(ByVal sender As Object, ByVal e As RoutedEventArgs) ' load the main image into our viewer imageViewer1.Source = New BitmapImage(New Uri("C:\Users\Public\Documents\LEADTOOLS Images\eye.gif")) ' we are in design mode now currentUserMode = UserModeEnum.DesignMode If (Not imageViewer1.Source Is Nothing) Then ' initialize the AnnContainer object and associate it with rasterImageViewer1 image annContainerObj = New AnnContainer() annContainerObj.Width = imageViewer1.Source.Width annContainerObj.Height = imageViewer1.Source.Height ' set the annContainerObj as a content of BitmapSourceViewer. imageViewer1.Content = annContainerObj ' create Annotation Button Object and add it to the container annContainerObj.Children.Add(CreateAnnButtonObject(New Rect(1, 1, annContainerObj.Width / 4, annContainerObj.Height / 4))) ' create Annotation Note Object and add it to the container annContainerObj.Children.Add(CreateAnnNoteObject(New Rect(annContainerObj.Width / 2, annContainerObj.Height / 2, (annContainerObj.Width / 4) - 1, (annContainerObj.Height / 4) - 1))) 'handle the container MouseLeftButtonDown event AddHandler annContainerObj.MouseLeftButtonDown, New MouseButtonEventHandler(AddressOf annContainerObj_MouseLeftButtonDown) End If End Sub Sub annContainerObj_MouseLeftButtonDown(ByVal sender As Object, ByVal e As MouseButtonEventArgs) If (imageViewer1.Source Is Nothing) Then Return End If If (currentUserMode = UserModeEnum.RunMode) Then Dim obj As AnnObjectBase = annContainerObj.HitTest(e.GetPosition(annContainerObj)) If ((Not obj Is Nothing) AndAlso ((TypeOf obj Is AnnButtonObject) Or (TypeOf obj Is AnnNoteObject))) Then If (TypeOf obj Is AnnButtonObject) Then Dim buttonObj As AnnButtonObject = obj buttonObj.IsPushed = True HandleHyperLink(buttonObj) buttonObj.IsPushed = False Else Dim annNoteObj As AnnNoteObject = obj HandleHyperLink(annNoteObj) End If End If End If End Sub Private Sub CheckedChanged(ByVal sender As Object, ByVal e As RoutedEventArgs) UserModeChanged(sender) End Sub Private Sub UserModeChanged(ByVal sender As Object) currentUserMode = IIf(sender Is rbDesignMode, UserModeEnum.DesignMode, UserModeEnum.RunMode) End Sub Private Function CreateAnnButtonObject(ByVal boundingRect As Rect) As AnnObjectBase Dim annButtonObj As AnnButtonObject = New AnnButtonObject() annButtonObj.Text = "Click me" annButtonObj.TextBrush = Brushes.Red annButtonObj.Stroke = Brushes.Red annButtonObj.StrokeThickness = 3 annButtonObj.Fill = Brushes.Yellow annButtonObj.FontFamily = New FontFamily("Arial") annButtonObj.FontSize = 14 annButtonObj.FontWeight = FontWeights.Bold annButtonObj.Hyperlink = "www.leadtools.com" annButtonObj.Left = boundingRect.Left annButtonObj.Top = boundingRect.Top annButtonObj.Width = boundingRect.Width annButtonObj.Height = boundingRect.Height Return annButtonObj End Function Private Function CreateAnnNoteObject(ByVal boundingRect As Rect) As AnnObjectBase Dim annNoteObj As AnnNoteObject = New AnnNoteObject() annNoteObj.Text = "This is my Text" annNoteObj.TextBrush = Brushes.Red annNoteObj.Stroke = Brushes.Red annNoteObj.StrokeThickness = 3 annNoteObj.Fill = Brushes.Yellow annNoteObj.FontFamily = New FontFamily("Arial") annNoteObj.FontSize = 14 annNoteObj.FontWeight = FontWeights.Bold annNoteObj.Hyperlink = "Notepad.exe" annNoteObj.Left = boundingRect.Left annNoteObj.Top = boundingRect.Top annNoteObj.Width = boundingRect.Width annNoteObj.Height = boundingRect.Height Return annNoteObj End Function Private Sub HandleHyperLink(ByVal obj As AnnObjectBase) If (Not obj.Hyperlink = String.Empty) Then Try System.Diagnostics.Process.Start(obj.Hyperlink) Catch ex As Exception MessageBox.Show(ex.Message, "Error", MessageBoxButton.OK, MessageBoxImage.Exclamation) End Try End If End Sub

Build, and Run the program to test it. Click on the Note and Button annotations. Since the User Mode is Design Mode, nothing happens. Select Run Mode Radio button then click on each annotation.
