from where i get dsofile supports 64 bit?

i am struggling to add new custom properties in Excel from my vb.net app. me have 64 bit machine and Office 2013 installed. i believe this issues is because of my dsofile will not work in 64 bit machine.

me already have code which work for 32 bit machine + Office 2007

Hi Rosh,

Here is a blog article regarding using Dsofile on 64 bit OS:

http://blogs.msdn.com/b/vsod/archive/2012/10/20/considerations-when-using-dsofile-on-64-bit-operating-systems.aspx

For Office 2010 and Office 2007, there are hotfix available to fix the problem. And so far I haven't found the hotfix for Office 2013.

As it mentioned int he blog article:

If you wish to use DSOFile from a 64 bit program, then you should recompile the DSOFile to target for 64 bit.

An alternative approach to using Dsofile would be to use Open Xml SDK (or System.IO.Packaging). A sample that demonstrates this is given below:

 CoreFilePropertiesPart coreFileProperties = package.CoreFilePropertiesPart;
 
 System.IO.Stream stream = coreFileProperties.GetStream();
 
 XDocument xdoc = XDocument.Load(coreFileProperties.GetStream());
 
 // Display default properties 
 IEnumerable<XElement> awElements = from el in xdoc.Descendants()
 where el.Name.Namespace == "http://schemas.openxmlformats.org/package/2006/metadata/core-properties"
 select el;
 foreach (XElement el in awElements)
 
 Console.WriteLine(el.Name.LocalName + " = " + el.Value.ToString());
 
 Console.ReadLine();
 }
 }
 catch (Exception ex)
 {
 System.Windows.Forms.MessageBox.Show(ex.Message);
 }
 }
 }
 }
