Interop.Word print preview dialog for office 2010/2013

Question

In my application I have word template with tags which are later replaced using interop.word (find/replace) and then sent to print using print preview dialog: Interop.Word.Application.Dialogs[WdWordDialog.wdDialogFilePrint]

On a result of a dialog I am printing or closing the document.

For office 2003 and 2007 this is working absolutely fine, but in office 2010 later print preview dialog is absolutely different.

I've found related post here but I need to grab dialog result so that i could further do print or close the doc.

Is there any workaround or soultions for that?

Answer 1

Just for the future reference posting answer to my own question. Finally I could figure it out.

Following code is working with any version of Word fine. While dialog is open application freezes and waits for a result just as another dialogs.

The only moment is it allows to choose appropriate printer only, but does not show preview.

             _doc.Activate();
             _wordApp.Visible = true;

             var dialogResult = _wordApp.Dialogs[WdWordDialog.wdDialogFilePrint].Show();

             if (dialogResult == 1)
                 _doc.PrintOut();

Here is some code that will hopefully help you get closer that I wrote for Interop for Office 2000 years ago. I tested it with Office 2007 and it works, but don't have 2010 to test atm.

I'm assuming you already have the Interop references.

using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace printdialog
{
    public partial class Form1 : Form
    {
        Word.ApplicationClass WordApp;

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //Create Word Instance
            WordApp = OpenWordApplication();

             //Show Word
            WordApp.Visible = true;

            //Open a Word Doc
            OpenWordDocument(WordApp, "c:\\test.docx");


            DialogResult result = MessageBox.Show("Would you like to Print?", "PrintPreview", MessageBoxButtons.OKCancel);
            switch (result)
            {
                case DialogResult.OK:
                    {
                        WordApp.PrintPreview = true;
                        //if preview call above doesn't work try the call below 
                        //WordApp.ActiveWindow.View.Type = Word.WdViewType.wdPrintPreview;
                        break;
                    }
                case DialogResult.Cancel:
                    {
                        CloseWordApplication(WordApp);
                        break;
                    }
            }
        }
