Hello

Is it possible to save richtextbox-text so, that the page is in landscape format ?

Rtf-file contains parameters of page settings and I have tried to modify those parameters, but with no success.

I have not been able to set those parameters at all. Is it so that richtextbox does not allow to set Richtextbox.rtf - value ?

I have tried to modify rtf-code by setting the "\landscape" or "\lndscpsxn" parameters into rtf-code by:

MyRtb.rtf = "{\rtf1\...
or
MyRtb.selectedrtf = "{\rtf1\...

Those lines don't change MyRTb.rtf value. What's wrong ?

you're using windows form richtextbox?

Yes, Windows form RichTextBox.

You managed to spell "RTF" wrong.

What if the end user does not have Microsoft Word ?
Is there a way to set the rtf-code without using Microsoft Word ?

Can it be done trough RichTextBox-object ?

I'm sorry I don't understand. You say you want to save a RTF file and set its page settings to landscape, and you have some links to resolve that. Obviously any user that wants to read the file will need some program that accepts RTF, either MS Word or similar.

Yes. The user, who opens the file must have Word or similar program to read the rtf-file.

But, the user (end user), who creates the rtf-file with my application does not necessarily have MS Word.

In that case your code needs to ensure that the file is fully compliant with the RTF specification.

Could You explain what you mean?

Richard MacCutchan16-Dec-11 0:16

What more can I say? You are saving a file as RTF so you need to ensure that its content follows the RTF format specification. If you still don't understand then I suggest taking a look here[^].

Yes you are right, the file must follow rtf-format specification.
As I mentioned earlier, I have tried to make the file to follow rtf format by following way:

Rtf-file contains parameters of page settings and I have tried to modify those parameters, but with no success. I have not been able to set those parameters at all. Is it so that richtextbox does not allow to set Richtextbox.rtf - value ?

I have tried to modify rtf-code by setting the "\landscape" or "\lndscpsxn" parameters into rtf-code by:

or
MyRtb.selectedrtf = "{\rtf1\...

Those lines don't change MyRTb.rtf value.

Sorry but this makes no sense. Explain clearly what your program is trying to do, show the actual lines of code (surrounded by <pre> tags so it's readable) and what results you get.

OK
There is RichTextBox (MyRtb), which content is saved as rtf-file.
Rtf-file contains page formatting data, which I have tried to modify so that the page orientation is Landscape.

I have tried to set Document Formatting Property "\landscape" and
Section Text Property "\lndscpsxn".

Those properties are documented in rtf specification.

Code lines, which I used for setting those properties:

<pre lang="vb">Myrtb.Rtf = "{\rtf1\landscape}"</pre>
<pre lang="vb">Myrtb.Rtf = "{\rtf1\lndscpsxn}"</pre>

Well, it might be that those parameters are not in the right place in rtf-code.
But anyway, it seems that those lines do not affect rtf code at all.

And the main question is: Is it possible at all (in code) to modify rtf-file so that the page orientation is in Landscape mode ?

Myrtb.Rtf = "{\rtf1\landscape}
Myrtb.Rtf = "{\rtf1\lndscpsxn}

If that is all the code you have I don't see how it can affect anything. Where do you modify the contents of your RTF file before saving it?

sText is String, which contains text and linefeeds

<pre lang="vb">Myrtb.SelectionColor = Color.Black</pre>
<pre lang="vb">Myrtb.SelectionFont = New Font("Microsoft Sans Serif", 14, FontStyle.Bold, GraphicsUnit.Point)</pre>
<pre lang="vb">Myrtb.SelectedText = sText </pre>

<pre lang="vb">Myrtb.Rtf = "{\rtf1\landscape}</pre>
<pre lang="vb">Myrtb.Rtf = "{\rtf1\lndscpsxn}</pre>

<pre lang="vb">Myrtb.SaveFile(Me.SaveFileDialog.FileName, RichTextBoxStreamType.RichText)</pre>

Richard MacCutchan16-Dec-11 2:29

Please format your code properly, it only needs one set of tags around it and should appear thus:

Myrtb.SelectionColor = Color.Black
Myrtb.SelectionFont = New Font("Microsoft Sans Serif", 14, FontStyle.Bold, GraphicsUnit.Point)

You also probably need to uncheck the box titled "Treat my content as plain text, not as HTML ".

See here[^] for some suggestions as to formatting; it suggests your \landscape command comes before your text.

Ok, thank you.

The only solution offered for this problem in the web is this MS Word solution, and it is quite "rough" programming.

So I wonder if it's possible at all (in code) to set/modify rtf-code part of the rtf-file.

AFAIK every Windows version includes a copy of WordPad, which natively uses the RTF format. It also is the application associated with the RTF extension until you install something that replaces that association (such as MS Word).

I use RTF a lot, I have classes to generate RTF documents, then open them in WordPad for the user to inspect, modify if necessary, print, etc.

RTF is a complex language, its manual is hundreds of pages. Generating a valid document is quite doable, altering an existing one can be a real challenge.

The RTF specification is extensive, and programs that accept and/or generate RTF documents pick and choose what subset of commands they use.

I performed a little test using Wordpad 6.0 (on Vista), creating, printing, storing and inspecting a simple RTF file both in portrait and in landscape. My observations include:

- margin information was not stored in the document itself.
- paper orientation was not stored in the document itself.
- both are settings for Wordpad, not for the document; when you open Wordpad, you get what you had last time in Wordpad.

As Wordpad seems to consider these app settings rather than document settings, I expect it will ignore the relevant commands if they were present in the file (I haven't tested this).

FYI: Wordpad can show much more complex RTF documents than it allows the user to create; as an example, it can show tables, graphs, and images; things it doesn't offer the means for to insert in an empty document.

Thanks for clarifying WordPad behaviour.
So, the WordPad does not care about document page setting.

But, if the user opens document for example with MS Word, then these settings coul be used.

I managed to set the rtf-code by following way. I dont know whether it's clever way or not, but MS Word understood it and opened document in landscape.

The created and saved rtf-file is reopened, page settings are inserted into rtf-code, and finally file is saved again.

Me.rtbPrint.SaveFile(Me.SaveFileDialog.FileName, RichTextBoxStreamType.RichText)
Dim FILE_NAME As String = Me.SaveFileDialog.FileName
Dim objReader As New System.IO.StreamReader(FILE_NAME)
Dim sString = objReader.ReadToEnd
objReader.Close()
sString = sString.Insert(6, "\paperw15840\paperh12240\margl720\margr144\margt720\margb288\lndscpsxn")
Dim objWriter As New System.IO.StreamWriter(FILE_NAME)
objWriter.Write(sString)
objWriter.Close()

Hope, that the code is seen properly.
