Adding Text Dynamically using VSTO and Aspose.Slides for .NET

Adding Text Dynamically

Both methods follow these steps:

  1. Create a presentation.
  2. Add a blank slide.
  3. Add a text box.
  4. Set some text.
  5. Write the presentation.

VSTO Code Example

The code snippets below results in a presentation with a plain slide and a string of text on it.

The presentation as created in VSTO


//Note: PowerPoint is a namespace which has been defined above like this
//using PowerPoint = Microsoft.Office.Interop.PowerPoint;

//Create a presentation
PowerPoint.Presentation pres = Globals.ThisAddIn.Application

//Get the blank slide layout
PowerPoint.CustomLayout layout = pres.SlideMaster.

//Add a blank slide
PowerPoint.Slide sld = pres.Slides.AddSlide(1, layout);

//Add a text
PowerPoint.Shape shp = sld.Shapes.AddTextbox(Microsoft.Office.Core.MsoTextOrientation.msoTextOrientationHorizontal, 150, 100, 400, 100);

//Set a text
PowerPoint.TextRange txtRange = shp.TextFrame.TextRange;
txtRange.Text = "Text added dynamically";
txtRange.Font.Name = "Arial";
txtRange.Font.Bold = Microsoft.Office.Core.MsoTriState.msoTrue;
txtRange.Font.Size = 32;

//Write the output to disk

Aspose.Slides for .NET Example

The code snippets below use Aspose.Slides to create a presentation with a plain slide and a string of text on it.

The presentation as created using Aspose.Slides for .NET


//Create a presentation
Presentation pres = new Presentation();

//Blank slide is added by default, when you create
//presentation from default constructor
//So, we don't need to add any blank slide
ISlide sld = pres.Slides[1];

//Add a textbox
//To add it, we will first add a rectangle
IShape shp = sld.Shapes.AddAutoShape(ShapeType.Rectangle, 1200, 800, 3200, 370);

//Hide its line
shp.LineFormat.Style = LineStyle.NotDefined;

//Then add a textframe inside it
ITextFrame tf = ((IAutoShape)shp).TextFrame;

//Set a text
tf.Text = "Text added dynamically";
IPortion port = tf.Paragraphs[0].Portions[0];

port.PortionFormat.FontBold = NullableBool.True;
port.PortionFormat.FontHeight = 32;

//Write the output to disk
pres.Save("c:\\outAspose.ppt", SaveFormat.Ppt);
