Hi, i want to open word file in a rich text box with images,bullets and texts
and then i want line by line sentences.
I am using this code-

C#

Microsoft.Office.Interop.Word.ApplicationClass wordObject = new Microsoft.Office.Interop.Word.ApplicationClass(); 
object File = txtfilepath.Text; //this is the path
 object nullobject = System.Reflection.Missing.Value; Microsoft.Office.Interop.Word.Application wordobject = new Microsoft.Office.Interop.Word.Application();
 wordobject.DisplayAlerts = Microsoft.Office.Interop.Word.WdAlertLevel.wdAlertsNone; Microsoft.Office.Interop.Word._Document docs = wordObject.Documents.Open(ref File, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject); docs.ActiveWindow.Selection.WholeStory();
 docs.ActiveWindow.Selection.Copy(); 
IDataObject data = Clipboard.GetDataObject(); 
rtbgermanfile.Text = data.GetData(DataFormats.Rtf).ToString();
 string name = rtbgermanfile.Text.Trim(); name = String.Join(Environment.NewLine, name.Split(new char[] { '.' }, StringSplitOptions.RemoveEmptyEntries)); 
string newtext = name.Replace("\n\n", "\n");
 string newtext2 = newtext.Replace("\n\n", "\n");
 rtbgermanfile.Text = newtext2.ToString(); 
txtwriteingerman.Text = rtbgermanfile.Lines[0]; 
docs.Close(ref nullobject, ref nullobject, ref nullobject);
 wordobject.Quit(ref nullobject, ref nullobject, ref nullobject);
 //wordobject.Quit(SaveChanges:false, OriginalFormat: false, RouteDocument: false);

The class RichTextBox supports only RTF format, and pretty purely. There is a dirty way to insert a picture in it using clipboard:

For example:

C#

Image img = Image.FromFile("myImage.jpg");
Clipboard.SetImage(img);
myRichTextBox.SelectionStart = 0; //for example; you need some position to insert it
myRichTextBox.SelectionLength = 0;
myRichTextBox.Paste();

However, you can face too many problems with that.

I would advice you to use some alternative. Instead of Rich Text Format, you could use HTML. I would recommend this wonderful component offered in this CodeProject article:

A Professional HTML Renderer You Will Use[^].

The work I referenced above is excellent! Why do you need such brain damage as RTF is you can use very rich HTML? The author of this work developed such a wonderful thing as a support for special URL schema to include images and other resources from the resource embedded in the executable. This is a nearly perfect method of presentation of structured read-only documents without using of the WebBrowser control.

One more alternative: use WPF. It has excellent support for Rich documents and XPS. Please see my recent answer on XPS viewer:
The XPS Document Viewer Sample In Intersoft ClientUI[^].
