Question

Using VSTO, I’ve created a custom tab in the Ribbon designer and added some groups and button controls there. When user clicks one of the buttons, I’d like to connect to a SharePoint site and open a word document from it in Word (an instance is already open). I’m able to connect to the SharePoint site already and have the URLs to the documents I want to open.

But how can I actually load these documents into Word? I’m already in the code-behind in Word, so how can I target the Word instance I’m in and open a file there?

Thanks in advance.

You would have to use the Word API to open a document. See this link for a reference. You may have to update it based on the API version you use.

private void button1_Click(object sender, System.EventArgs e) {     // Use the open file dialog to choose a word document     if (this.openFileDialog1.ShowDialog() == DialogResult.OK)     {         // set the file name from the open file dialog         object fileName = openFileDialog1.FileName;         object readOnly = false;         object isVisible = true;         // Here is the way to handle parameters you don't care about in .NET         object missing = System.Reflection.Missing.Value;         // Make word visible, so you can see what's happening         WordApp.Visible = true;         // Open the document that was chosen by the dialog         Word.Document aDoc = WordApp.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);         // Activate the document so it shows up in front         aDoc.Activate();         // Add the copyright text and a line break         WordApp.Selection.TypeText('Copyright C# Corner');         WordApp.Selection.TypeParagraph();     } }
