Save Word Document from C# AddIN refuses to work

[karenina]

Hello there.

I try to develop an Office plugin (in C#, .NET Framework 1.0) which is
supposed to manage some documents. I am trying to save the custom
properties for an word document and then send this document via email.
I though the steps are:

- let the user select the document (therefore open the document)
- let the user write the properties (using some simple Windows Form
that allows the user to enter the name and the value of the properties)
- update the custom props on the document
- save the document
- close the document
- get the byte[] and use them however I want.

The problem is the Save method is not working. I found this out by
re-opening the document after it was closed. I can find all the new
props on my Document object, but after I close and load the document,
there are no props there.

Can someone please help me?

I am using C#, .NET framework 1.0 (the application is really big and
there is no time to transfer it to 1.1 or 2.0 at this moment, so I have
to use framework 1.0), Microsoft Office 2003 and I downloaded the
latest PIAs from Microsoft. I alse copied the dlls from the PIAs to my
own project and used that ones.

Thanks a lot for your time.

Hello

I'm using custom properties and document variables in my .NET1 addin for
Word2003.

Both are saved correclty

this.appWord.ActiveDocument.Save();

Maybe there's a problem with the update of your custom props

Here's my code, hope It will help you;

public void SetDocCustomProp(string propName, string propValue)
{

try
{
object customPropertiesObject =
this.appWord.ActiveDocument.CustomDocumentProperties;
Type propertyType = customPropertiesObject.GetType();

object[] oArgs =
{propName,false,MsoDocProperties.msoPropertyTypeString,propValue};
try
{
propertyType.InvokeMember("Add",System.Reflection.BindingFlags.Default
| System.Reflection.BindingFlags.InvokeMethod, null,customPropertiesObject,
oArgs );
}
catch(Exception)
{
propertyType.InvokeMember("Item",BindingFlags.Default |
BindingFlags.SetProperty,null,customPropertiesObject,new object[]
{propName,propValue} );
}

}
catch (Exception e)
{
Clipboard.SetDataObject(e.ToString(),true);
MessageBox.Show(e.ToString(),"Error",MessageBoxButtons.OK,MessageBoxIcon.Error);
}

}

I think I've seen this problem. It was a while back, but I think I remember
that if you open a Word doc, modify the value of an existing Custom Document
Property, and then call Save, nothing happens (your changes are not saved).
I think this is because Word doesn't consider the document to be changed
(which is clearly a bug). As I recall, I had to make a change to the body of
the document so that Word knows it has to be saved. You might be able to set
the Document.Saved propery to False instead.

Thanks for your reply. I believe there is indeed a bug since I set the
properties and the Saved property of the Word Document is true.
I managed to solve this by setting this property to false (which tells
Word Application that it should indeed save the changes).
After that it worked fine.

Thanks a lot,

Roxana.
