22.7 How can I load an embedded rich text file into a richtextbox?

You use the LoadFile method of the RichTextBox, passing it a streamreader based on the resource. So include your RTF file as an embedded resource in your project, say RTFText.rtf. Then load your richtextbox with code such as

Stream stream = this.GetType().Assembly.GetManifestResourceStream("MyNameSpace.RTFText.rtf");

if (stream != null)

{

StreamReader sr = new StreamReader(stream);

richTextBox1.LoadFile(stream, RichTextBoxStreamType.RichText);

sr.Close();

}

Here is a VB snippet. Depending on your default namespace settings, you may not need explicit reference to the namespace in the GetManifestResourceStream argument.

Dim stream As Stream = Me.GetType().Assembly.GetManifestResourceStream("MyNameSpace.RTFText.rtf")

If Not (stream Is Nothing) Then

Dim sr As New StreamReader(stream)

richTextBox1.LoadFile(stream, RichTextBoxStreamType.RichText)

sr.Close()

End If
