Hi Aspose team,

I found how to add comment to comment to page (

http://www.aspose.com/docs/display/diagramnet/Add+Comments+to+Visio+Drawings)

Now question is how can I loop through existing comments and make their changes.

In attached document you have few comments (on page and on shape level) and then I am trying to read content of comment I am always getting "".

Code is very simple:

For Each page As Page In officeDocument.Pages
For Each shp As Shape In page.Shapes

oldText = shp.Misc.Comment.Value


Btw. this works for comments on shape but how to access existing comments on page level?

I found only Page.AddComment

How to access page comment?

How to change page and shape comments?

Thanks,
Oliver

Hi Imran,

I just saw that you released 6.1.0 with enhancement: DIAGRAMNET-50570-Add support to modify comments in the Visio diagram.

Now on page level I see that there is AddComment so I suppose that this was the change, right?
Can you give some example how I can loop through all comments and make from code comment text change?

Thanks in advance,
Oliver

Hi Oliver,


Thank you for being patient. Please use this sample code:

[.NET, C#]
// load Visio
Diagram diagram = new Diagram(“C:/temp/Drawing1.vsdx”);
// collection of the annotations
AnnotationCollection annotations = diagram.Pages.GetPage(“Page-1”).PageSheet.Annotations;

// iterate through the annottions
foreach (Annotation annotation in annotations)
{
Console.WriteLine(annotation.Comment.Value);
string comment = annotation.Comment.Value;
comment += “Updation mark”;
annotation.Comment.Value = comment;
}
// save Visio
diagram.Save(“C:/temp/result.vsdx”, SaveFileFormat.VSDX);
