using SoftArtisans.OfficeWriter.PowerPointWriter;

2. Instantiate the PowerPointTemplate object.

PowerPointTemplate PPTT = new PowerPointTemplate();

3. Open the template file with PowerPointTemplate.Open.
The PowerPointTemplate object corresponds to a single template file, so a given PowerPointTemplate instance can only have one template file open.

PPTT.Open(Page.MapPath("templates\\Hello World.pptx"));

4. Create a DataBindingProperties object

DataBindingProperties DataProps = PPTT.CreateDataBindingProperties();

The DataBindingProperties object can be used to change the behavior of how data is imported. For example, if we were importing multiple rows of data, we can use the DataBindingProperties.MaxRowsPerSlide property to limit the number of rows that are imported. In this sample, we won't be changing any of the import properties, but we still need the DataBindingProperties object to bind data.

...

string value = DataValueBox.Text.Trim();
string[] values = { value };
string[] colNames = { "DataValue" };

Dim value As String = DataValueBox.Text.Trim()
Dim values = New String() { value };
Dim colNames = New String() { "DataValue" };

6. Call PowerPointTemplate.BindData() to bind the data to the data marker. The data source name should match the value in your data marker.

{vbnet:6}
PPTT.BindData(values, colnames, "DataSource1", DataProps);

Note that we need to pass the DataBindingProperties object, even though none of the DataBindingProperties are active.

7. Call PowerPointTemplate.Process() to insert the data into the file

PPTT.Process();

PowerPointTemplate.Process() handles everything relating to inserting the data into the file.

...

PPTT.Save(Page.Response, "Output.pptx", false);

There are several options for PowerPointTemplate.Save including: save to disk, save to memory stream, stream back to the client inline, and stream back to the client as an attachment. In this case, we're streaming the presentation back to the client as an attachment.
Also, PowerPointWriter does not convert between file formats, so it is important that the file extension on the output file matches the file extension of the original template file.

...

using SoftArtisans.OfficeWriter.PowerPointWriter;
...
PowerPointTemplate PPTT = new PowerPointTemplate();
PPTT.Open(Page.MapPath("Hello World.pptx"));
DataBindingProperties DataProps = PPTT.CreateDataBindingProperties();
string value = DataValueBox.Text.Trim();
string[] values = { value };
string[] colNames = { "DataValue" };
PPTT.BindData(values, colNames, "DataSource1", DataProps);
PPTT.Process();
PPTT.Save(Page.Response, "Output.pptx", false);

Imports SoftArtisans.OfficeWriter.PowerPointWriter
...
Dim PPTT As New PowerPointTemplate()
PPTT.Open(Page.MapPath("templates\Hello World.pptx"))
Dim DataProps As DataBindingProperties = PPTT.CreateDataBindingProperties()
Dim value As String = DataValueBox.Text.Trim()
Dim values() As String = New String() { values }
Dim colNames = New String() { "DataValue" }
PPTT.BindData(values, colNames, "DataSource1", DataProps)
PPTT.Process()
PPTT.Save(Page.Response, "Output.pptx", False)
