i have created a small application to store files in particular folders using drag and drop. (i am not very experienced so please help)
i now able to search through the main folder and its sub folders, everything ok so far. My search lists the found items in a list box (say all word docs)i use the following code and it opens the main interface but will not allow me to open the word doc. i am doing this modularly so it is a single form.

i have included the whole form the area for concern is:
private void button2_Click_1(object sender, System.EventArgs e)
thank you.

Word Documents you cannot open liek this, See the following code to open, read and display the contents in text box.

First add a reference to Microsoft.Office.Core in the project
Make the TextBox multi line property to True, then add the execute the following code to load a word document to the text box.


object fileName = @"test.DOC";
object readOnly = false;
object isVisible = true;
object missing = System.Reflection.Missing.Value;
Word.ApplicationClass oWordApp = new Word.ApplicationClass();

Word.Document oWordDoc = oWordApp.Documents.Open(ref fileName, ref missing,ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref isVisible, ref missing,ref missing,ref missing, ref missing);

Word._Document WordAppDoc = new Word.DocumentClass ();
WordAppDoc.Application = oWordApp;

textBox1.Text = oWordDoc.Content.Text.ToString ();
