- Add a blank slide.
- Add a text box.
- Set some text.
- Write the presentation.
VSTO
private void AddTextBox()
{
//Create a presentation
PowerPoint.Presentation pres = Globals.ThisAddIn.Application
.Presentations.Add(Microsoft.Office.Core.MsoTriState.msoFalse);
//Get the blank slide layout
PowerPoint.CustomLayout layout = pres.SlideMaster.
CustomLayouts[7];
//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
pres.SaveAs("outVSTOAddingText.ppt",
PowerPoint.PpSaveAsFileType.ppSaveAsPresentation,
Microsoft.Office.Core.MsoTriState.msoFalse);
}
Aspose.Slides
static void AddTextBox()
{
//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
Slide sld = pres.GetSlideByPosition(1);
//Get the font index for Arial
//It is always 0 if you create presentation from
//default constructor
int arialFontIndex = 0;
//Add a textbox
//To add it, we will first add a rectangle
Shape shp = sld.Shapes.AddRectangle(1200, 800, 3200, 370);
//Hide its line
shp.LineFormat.ShowLines = false;
//Then add a textframe inside it
TextFrame tf = shp.AddTextFrame("");
//Set a text
tf.Text = "Text added dynamically";
Portion port = tf.Paragraphs[0].Portions[0];
port.FontIndex = arialFontIndex;
port.FontBold = true;
port.FontHeight = 32;
//Write the output to disk
pres.Write("outAspose.ppt");
