Load VS.NET class files in RTB pertaining syntax color?

I tried this but it throw an error saying : "Invalid file format" .

VB Code:

Me.RichTextBox1.LoadFile("c:\a.cs", RichTextBoxStreamType.RichText)

but

when I try this , it works WITHOUT keywords color

VB Code:

Me.RichTextBox1.LoadFile("c:\a.cs", RichTextBoxStreamType.PlainText)

I need to load the file in RTB pertaining syntax coloring .

Anybody knows why it making that error ??

Thanks

The data in the file is not Rich Text its just plain text hence the error. The IDE itself is doing the coloring, its not in the file itself. Rich Text is like a language all its own. You can find specs for the Rich Text format on the web here is one: http://www.microsoft.com/downloads/d...displaylang=en

You mean , I should handle keywords coloring after loading the file as plain text format?

Yes because the file doesn't have any information about coloring in it. You can open it in Notepad to see what it has and it'll be just the plain text. If you want to see what rtf looks like then save a word document as RTF then open it in Notepad. You'll see a bunch of stuff mixed in with the text.

Thanks Edneeis . I'll spend some time reading some stuff in that document .
