Copy MS Word Paragraph to RichTextBox with formatting

[Guest]

Hi

Is there a way thru automation to extract a paragraph from a word document
and put into a RichTextBox with the original Word formatting.

Roght now I only get the plain text from para.Range.Text

Thanks

Hello sippyuconn,

From your post, my understanding on this issue is: you want to copy a
certain paragraph of a word document to a rich text box. If I'm off base,
please feel free to let me know.

I think you may use the Copy method to copy the paragraph into clipboard
first, then paste it into the RichTextBox control. Please refer to the
following sample code which is for a winform project.

Dim app As Word.Application
app = CreateObject("Word.Application")
app.DisplayAlerts = Word.WdAlertLevel.wdAlertsNone

Dim doc As Word.Document
doc = app.Documents.Open("d:\test.docx")
doc.Paragraphs(1).Range.Copy()
Me.RichTextBox1.Paste()
doc.Close()
app.DisplayAlerts = Word.WdAlertLevel.wdAlertsAll

Please let me know if you have any other concerns, or need anything else.

Sincerely,

Hi

That is what I need - one more question

If I do this process using VBA thru Word it takes about 10 seconds

If I run this code thru DotNet C# calling word it takes 15 minutes to process
30,000 paragraphs. Is the way I am doing this in DotNet correct or is there a
faster way???

Thanks

ApplicationClass WordApp;

public WordDoc(string sFileName)
{
WordApp = new ApplicationClass();
WordApp.Visible = false;
FileName = sFileName;
}

public void Process()
{


object read_only = false;
object visible = true;
object ofalse = false;
object otrue = true;
object dynamic = 2;
object missing = System.Reflection.Missing.Value;
object oFileName = FileName;

Document Doc = WordApp.Documents.Open(ref oFileName, ref
missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref
missing, ref missing,
ref missing, ref missing, ref missing, ref
missing, ref missing);


for(int i = 1; i <= Doc.Paragraphs.Count; i++)
{
string sLine = Doc.Paragraphs.Range.Text;


.....

}

Hello sippyuconn

Yes, the way you are doing this in .Net is correct.

The performance of a ".NET-COM interop" application does lag behind VBA and
COM approaches. There are several factors that influence the performance:
1. The .net start up cost is inherently expensive. Applications written
with .net must incur the overhead of JIT compilation. JIT compilation is a
necessary evil and cannot be avoided. However, steps may be taken to reduce
the performance expense of JIT compilation. One approach is to use the
NGEN.exe which forces a JIT compilation of all the methods in the assembly.
Since the methods are Jitted, JIT compilation is no longer necessary when
the application first starts up.
2. Another performance factor influencing the process time is the expense
of calling through the thick layers of automation skin that wrap the
Microsoft office com objects. VBA, built and optimized to interact with
Microsoft office, has a shorter distance to travel than .NET.

Please let me know if you have any other concerns, or need anything else.
