Read Write Hyperlinks Microsoft.Office.Interop.Word

[SurferJoe]

Trying to read the hyperlink(s) from Word 2007 documents, make changes and
write them back. Being new to C#, I am not sure how to address the
Microsoft.Office.Interop.Word.Hyperlinks collection correctly.


Thanx in adavnce,

Hello Greg,

From your post, my understanding on this issue is: you want to know how to
manipulate Microsoft.Office.Interop.Word.Hyperlinks to read and edit
hyperlinks with C# in a Word 2007 document. If I'm off base, please feel
free to let me know.

Suppose that you have a C# project, first you need to confirm that the
Office PIA has been installed
(http://www.microsoft.com/downloads/details.aspx?familyid=59daebaa-bed4-4282
-a28c-b864d8bfa513&displaylang=en ) and the reference to
Microsoft.Office.Interop.Word has been added. (To add reference to
Microsoft.Office.Interop.Word, you need to right click the project in
Solution Explorer, choose 'Add Reference' and select 'COM' in 'Add
Reference' dialog, then find the 'Microsoft Word 12.0 Object Library' and
click OK.)

Secondly, the following codes get an instance of
Microsoft.Office.Interop.Word.Hyperlinks collection:
Word.Application applicationObject = new Word.Application();
object missing = Type.Missing;
object fileName = @"d:\test.docx";
object False = false;
applicationObject.DisplayAlerts = Word.WdAlertLevel.wdAlertsNone;
Word.Document documentObject = applicationObject.Documents.Open(
ref fileName, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref False, ref missing, ref missing,
ref missing, ref missing);
Word.Hyperlinks links = documentObject.Hyperlinks;

To read the links one by one, you can use the get_Item method of Hyperlinks
collection
for (int i = 1; i <= links.Count; i++)
{
object index = (object)i;
Word.Hyperlink link = links.get_Item(ref index);
}

The page
http://msdn2.microsoft.com/fr-fr/library/microsoft.office.interop.word.hyper
link_members(VS.80).aspx gives a detailed description of Hyperlink object.
Suppose that you want to edit the text and URL of a link, you can refer to
the following sample code:
Word.Hyperlink link = links.get_Item(ref index);
link.Address = "http://www.microsoft.com";
link.TextToDisplay = "Microsoft Home Page";

Finally, you may save the document and quit the Word.
documentObject.Save();
applicationObject.Quit(ref missing, ref missing, ref missing);

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

Sincerely,
Jialiang Ge ([email protected], remove 'online.')

Oh boy, I really appreciate your help with this.
Following code listing is what I worked out from your example.

We have recently purchased (50) Office 2007 upgrades, what I really need is
to expose the actual link address string like;
@"file://C:\Temp\Source Folder\Test Document #1.doc"

Evaluate the link(s) then write them back like this;

@"file://C:\Temp\Source Folder\Test Document #1.docx" // Please Note .DOCX

This excerpt from the code listing and many other variations I have tried
only returns only "Test Document" not @"file://C:\Temp\Source Folder\Test
Document #1.doc"

for (int i = 1; i <= links.Count; i++)
{
object index = (object)i;
Word.Hyperlink link = links.get_Item(ref index);
MessageBox.Show(link.Address);
Console.WriteLine(link.AddressOld);
}


//Code Listing
namespace WordReadHyperLinks
{
public partial class frmWordReadHyperlinks : Form
{
public frmWordReadHyperlinks()
{
InitializeComponent();
}

private void btnReadHyperlink_Click(object sender, EventArgs e)
{
Microsoft.Office.Interop.Word.Hyperlinks collection;
Word.Application applicationObject = new Word.Application();
object missing = Type.Missing;
object fileName = @"C:\Temp\Source Folder\Test Document #1.doc";
object False = false;
applicationObject.DisplayAlerts =
Word.WdAlertLevel.wdAlertsNone;
Word.Document documentObject = applicationObject.Documents.Open(
ref fileName, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref
missing,
ref missing, ref missing, ref False, ref missing, ref
missing,
ref missing, ref missing);
Word.Hyperlinks links = documentObject.Hyperlinks;

try
{

//To read the links one by one, you can use the get_Item
method of Hyperlinks
// collection
for (int i = 1; i <= links.Count; i++)
{
object index = (object)i;
Word.Hyperlink link = links.get_Item(ref index);
MessageBox.Show(link.Address);
Console.WriteLine(link.Address);
}
}
catch (Exception ex)
{
// Respond to the error
}
finally
{
// Close and release the Document object.
if (documentObject != null)
{
documentObject.Close(ref missing, ref missing,
ref missing);
documentObject = null;
}

// Quit Word and release the ApplicationClass object.
if (applicationObject != null)
{
applicationObject.Quit(ref missing, ref missing,
ref missing);
applicationObject = null;
}

GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
}
}

private void btnExit_Click(object sender, EventArgs e)
{
this.Close();

}
}
}
