Embedding PowerPoint documents in WPF

Some instruction on how to embed a PowerPoint presentation within a WPF application by converting the file to a XPS format and displaying this using DocumentViewer. Step 1: Create a WPF Application embedpowerpoint Step 2. Include the necessary references Microsoft.Office.Interop.PowerPoint embedpowerpoint2 Office powerpoint1 ReachFramework powerpoint2 Step 3: Insert DocumentViewer control into MainWindow.xaml [code language="xml"] <Window x:Class="DocumentViewer.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" Title="MainWindow" Height="350" Width="525"> <Grid> <DocumentViewer Name="DocumentviewPowerPoint" VerticalAlignment="Top" HorizontalAlignment="Left" /> </Grid> </Window> [/code] Step 4: Convert the PowerPoint file to XPS format and point the DocumentView.Document to it As demonstrated in the following code snippet. For MVVM style applications it would be very similar, except we would need to bind the 'Document' to some object property in the ViewModel. [code language="csharp"] using System; using System.IO; using System.Windows; using System.Windows.Xps.Packaging; using Microsoft.Office.Core; using Microsoft.Office.Interop.PowerPoint; using Application = Microsoft.Office.Interop.PowerPoint.Application; namespace DocumentViewer { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); const string powerPointFile = @"E:\temp\powerpoint.pptx"; var xpsFile = Path.GetTempPath() + Guid.NewGuid() + ".xps"; var xpsDocument = ConvertPowerPointToXps(powerPointFile, xpsFile); DocumentviewPowerPoint.Document = xpsDocument.GetFixedDocumentSequence(); } private static XpsDocument ConvertPowerPointToXps(string pptFilename, string xpsFilename) { var pptApp = new Application(); var presentation = pptApp.Presentations.Open(pptFilename, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse); try { presentation.ExportAsFixedFormat(xpsFilename, PpFixedFormatType.ppFixedFormatTypeXPS); } catch (Exception ex) { MessageBox.Show("Failed to export to XPS format: " + ex); } finally { presentation.Close(); pptApp.Quit(); } return new XpsDocument(xpsFilename, FileAccess.Read); } } } [/code] Running the sample program using a sample PowerPoint file shows that the PowerPoint is indeed embedded in the WPF application as shown: embedpowerpoint3

Using the Supervisor Controller Pattern to access View controls in MVVM

As discussed on a StackOverflow post , this is considered bad practice, so only use this when necessary. Step 1: Create a new WPF project Step 2: Add event handling code A number of classes are needed for doing command bindings in MVVM. Create the following classes and add to your Visual Studio project: RelayCommand.cs [code language="csharp"] using System; using System.Windows.Input; namespace SupervisorControllingPattern { public class RelayCommand<T> : ICommand { private readonly Predicate<T> _canExecute; private readonly Action<T> _execute; public RelayCommand(Action<T> execute) : this(execute, null) { _execute = execute; } public RelayCommand(Action<T> execute, Predicate<T> canExecute) { if (execute == null) throw new ArgumentNullException(nameof(execute)); _execute = execute; _canExecute = canExecute; ...

Getting started with client-server applications in C++

Image
A demonstration of simple Internet client-server applications in C++ (Linux-based). The client application tries to connect to the remote server application using the IP address of the remote server ('localhost' or 127.0.0.1) and the server port number which defaulted to 1234. The server application listens to port number 1234 for a connection request. When the server application receives the connection request it sends the text message "Hello!\r\n" to the client.

How to send an e-mail via Google SMTP using C#

First things first, some useful StackOverflow links: https://stackoverflow.com/questions/9201239/send-e-mail-via-smtp-using-c-sharp https://stackoverflow.com/questions/17462628/the-server-response-was-5-7-0-must-issue-a-starttls-command-first-i16sm1806350 To demonstrate how this is done I first create a new Visual Studio project: Some example code for sending an email via a Google email account (smtp.goolgle.com) - obviously replace this with email / credentials of your own... I put the code within a try-catch block in order to capture any errors that may occur while attempting this. [code language="csharp"] using System; using System.Net; using System.Net.Mail; namespace EmailSmtp { class Program { static void Main(string[] args) { try { // Credentials var credentials = new NetworkCredential("someEmail@gmail.com", "somePassword"); // Mail message var ...
