saving rich text box data!

[Lee]

Hi,

I have a rich text box that can have hyperlinks ect within the text!

when I save this data to file how should I do it? that is can I just save it
as text?

or do I need to serialize it beforehand to preserve the hyperlink info?

thanks in advance

If your rich text box is called "richTextBox1", you can load a file like
this:

this.richTextBox1.LoadFile("C:\\Document.rtf");

and save the content with this line:

this.richTextBox1.SaveFile("C:\\newFile.rtf");

sorry I wasn't very clear,

I am saving the rich text box data as part of an xml file.

thanks

You get the raw rtf from the "Rtf" method (this.richTextBox1.Rtf).
You would have to code this rtf formatted text into characters that XML can
store. XML can not store all charaters.

Format the rtf as Base64.

this.richTextBox1.LoadFile("C:\\Document.rtf");
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
string StoreMe =
System.Convert.ToBase64String(enc.GetBytes(this.richTextBox1.Rtf));
System.Windows.Forms.MessageBox.Show(StoreMe);

thanks.. but!

how on earth do I read the Base64 data back into a string?

thanks

Like this:

this.richTextBox1.LoadFile("C:\\Document.rtf");

// From RTF to Base64
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
string StoreMe =
System.Convert.ToBase64String(enc.GetBytes(this.richTextBox1.Rtf));
System.Windows.Forms.MessageBox.Show(StoreMe);

// Back from Base64 to RTF
byte[] result = System.Convert.FromBase64String(StoreMe);
string RTFString = enc.GetString(result);
System.Windows.Forms.MessageBox.Show(RTFString);
